Description

[0001]
BACKGROUND OF THE INVENTION
The present invention dissolves red rust generated inside water supply pipes arranged in various buildings, and supplies chemicals that form a thin film on the surface of black rust and the like that cannot be completely dissolved into the water supply pipes. The present invention relates to a rust prevention device in a water supply pipe that prevents the progress of rust and the generation of new rust and maintains the life of the water supply pipe over a long period of time.
[0002]
[Prior art]
Various methods have been put to practical use in order to prevent and suppress rust generated in the water pipes laid in the building. A method of changing the hydrogen ion concentration and oxidation-reduction potential through high-speed flowing water in a ceramic ball container subjected to special processing so that water and iron do not cause a corrosion reaction (see, for example, Patent No. 1740331), A method for melting a rust-preventing chemical (for example, see Patent Nos. 1912411, 1912412, and 1920278), a method for applying magnetic lines of force to water (for example, see Japanese Patent Publication No. 31-5341), and a combination thereof It is a system (for example, refer to Japanese Utility Model Laid-Open No. 4-27596).
[0003]
However, all of them have advantages and disadvantages in equipment installation costs, running costs, certainty of effects, etc. When applied to actual buildings based on experimental results in the laboratory, the effects as expected are not achieved. There are many examples. Here, the following description will be given focusing on a method of melting a drug, which is highly evaluated in terms of certainty.
[0004]
An anti-corrosion agent called “Sirifos” approved by the Ministry of Health and Welfare is known as a rust-preventing agent that is melted in water. In general, a configuration as shown in FIG. 1 is adopted.
[0005]
That is, the city water purchased through the water meter is accumulated in the water receiving tank 101 and pushed up to the top floor by the pumping pump 102. If there is an elevated water tank on the roof, the water is once stored here, and water is supplied to the water supply pipes and faucets on each floor by gravity. Moreover, when there is no elevated water tank, the pushed-up water will come out of a faucet directly through the water supply pipe of each floor. In the conventional technique, a pipe immediately after the pumping pump 102 is cut, and a pipe to the sealed drug container 103 is connected to the pipe, and a valve is attached to the cut existing pipe for use as a bypass when supplying medicine. Leave it. An opening / closing valve for stopping water at the time of drug replenishment is attached to the medicine container in front and back, and a pipe for returning the solution to the water receiving tank and a reflux amount adjusting valve 104 are attached. The solution concentration is controlled by adjusting the size of the drug container and the reflux amount, and a solution having a substantially constant concentration is constantly supplied.
[0006]
This method has the advantage that it does not require a pump for melting the rust preventive agent in water because it uses an existing push-up pump, but it has many disadvantages in the following aspects. Have both.
[0007]
First, in order to replenish rust-preventing chemicals, water must be prevented from passing through the container during replenishment, and a shunt circuit that bypasses the container is required. Must be installed.
[0008]
Secondly, since a solution having a sufficient concentration cannot be obtained only by passing water once through the drug container, it is necessary to repeat the treatment of returning some of the solution after passing through the container to the water receiving tank. For this reason, the piping for recirculation | reflux and the flow volume adjustment valve which adjusts a recirculation | reflux ratio are needed.
[0009]
Third, since the capacity of the container varies greatly depending on the size of the building and the amount of water used, it is necessary to prepare various types of containers. If you try to standardize various types of large and small containers and keep the number of types below a certain level, you will need to combine a plurality of containers together, and you will have to use multiple pipes depending on the number of containers. In accordance with “0007” and “0008” respectively indicated as first or second, large-scale waterworks must be performed.
[0010]
Fourth, the drug container is subjected to the backflow pressure of many tons of water filled in the water supply pipe leading up to the rooftop. In order to withstand this pressure and to prevent water leakage or damage to the container, the container must be made of strong stainless steel, etc., and to prevent water leakage. The lid of the medicine supply port through the packing must be tightened with a large number of bolts.
[0011]
Fifth, in order to make the remaining amount of medicine filled in the container visible from the outside, open a window in a part of the container such as stainless steel and put a transparent acrylic board etc. I must. This acrylic plate is also subjected to several tons of backflow pressure, so an extremely thick acrylic plate is required to maintain anti-destructive properties, and strict measures are taken to prevent water from leaking through the gap with the window frame. Sealing is required. This and the fact that it is indicated as the fourth in the above “0010” makes the container extremely expensive.
[0012]
Sixth, the pump that pushes up the water from the water receiving tank operates every time the user opens the faucet or whenever the float for detecting the water level provided in the elevated water tank installed on the roof falls below a certain position. . As a result, no matter what purpose the user uses, the solution of the drug is constantly flowing, not only the drug is wasted, but even if the user wants tap water without the drug, the faucet Only provides a drug solution.
[0013]
Seventh, the chemical approved by the Ministry of Health and Welfare (corrosion inhibitor for water supply) is colorless, tasteless and odorless, and the concentration required for normal rust prevention is about 5 to 6 ppm. It is indistinguishable that the drug is dissolved even if it is taken. This means that if you turn it over, it will be impossible to identify even if the medicine container is empty, and it will continue to run for months unless the remaining amount of medicine in the container is strictly controlled. There is a risk. In many cases, it takes several months for the medicine in the container to be completely consumed, so that it is easy to forget to replenish it, and if it is forgotten once, the period of idling tends to be long.
[0014]
Eighth, when replenishing medicines, open and close many valves in order, remove the bolts that firmly fix the lid of the container, refill the medicine and fix the lid again, and various valves It is not easy for anyone to do so in the reverse order. In order to avoid this trouble and the danger of idling, it will be necessary to entrust regular check-ups and drug replenishment to a contractor who has implemented the equipment work. I must.
[0015]
Ninth, since the rust inhibitor is always dissolved in tap water at a constant concentration, it is inevitable that the rust inhibitor will be ingested by the human body through boiled food, miso soup, rice cooking, etc. in addition to direct drinking. Some people just told me to mix the drug with tap water and showed an excessive rejection, explaining that "the safe drug approved by the Ministry of Health and Welfare is used below the specified concentration, so it does not affect the human body." However, it is not satisfactory and becomes a big obstacle to the spread of the device. Also, the question remains whether it can be said that there is really no effect.
[0016]
The reason why the rust preventive device in the water supply pipe using the rust preventive agent shown in the prior art is widely used in various buildings while having many of these drawbacks is as follows.
[0017]
First, when the phenomenon of red water or choro water begins to appear, the first "tube cleaning" that can be considered can remove the slime inside the tube, but it can hardly be expected to remove rust. This is to avoid damaging the rubber packing in the connection part of the piping, and in the case of an accident that accidentally swallows the cleaning liquid with tap water, can not use a very strong chemical? In addition, the time during which water is shut off for cleaning is limited to about half a day.
[0018]
Second, there is a method in which rust is removed by spraying high-pressure sand into the water supply pipe, and then the inner wall of the pipe is coated with vinyl chloride, but this is because vinyl chloride adheres to the bent part of the pipe. It has a limited life span of only about 5 years and can only be implemented once.
[0019]
Thirdly, since pure water is very stable, it can be temporarily altered in the form of separating negative ions or increasing the activity of water by the influence of electricity or magnetism from the outside. Even if it is possible, it is difficult to sustain the state, and it is easy to return to the original state in a short time, so after a long time to reach the end of the water supply pipe, existing rust is removed or new It is difficult to leave a force that suppresses the occurrence of rust.
[0020]
Fourthly, a device that generates electric potential by using the flow rate of water without using external power and thereby suppresses rust has been put into practical use, but the delivery results are biased toward chemical factories and the like. At the same time, it is expected that a considerable flow rate and amount of water are required, and it is unlikely that the same effect can be achieved with the amount of water used in ordinary homes and offices and the flow rate flowing through the water supply pipe.
[0021]
Fifth, devices based on a complicated theory of increasing the oxidation-reduction potential by the flow rate of water and the action of the catalyst have been on the market, and the strength was that there was no running cost. However, there have been a number of reports of ineffectiveness.
[0022]
Sixth, a method of degassing dissolved oxygen dissolved in water with a vacuum pump has been developed, and it is thought that generation and growth of rust can surely be suppressed, but the apparatus becomes large. Therefore, it has the disadvantage that it is not suitable for small and medium buildings.
[0023]
Seventh, chemicals can be demonstrating rust prevention effects in a simple experimental set, but they are difficult to understand, such as oxidation-reduction potential, negative ions, or passive regions based on a combination of pH and potential. It is difficult to understand what is based on it, and water treated based on these theories can only maintain its properties for a short time, so the effect cannot be confirmed in advance.
[0024]
Finally, if the pipes are changed, the indoor landscape will be significantly disturbed, and this will greatly reduce the asset value of the entire building and some condominiums of the building. In addition, it is necessary to take rust prevention measures as preventive maintenance, and if neglected, piping replacement costs ranging from 10 million yen to 30 million yen will be forced.
[0025]
Therefore, if it can be avoided with upfront investment of about 1.2 million yen to 3 million yen, the investment efficiency is not bad, but it is really effective as long as it aims to stop the decline in the asset value of the building Noh was the primary reason, and there was no choice but to worry about the effects on the human body. In this respect, the drug system is supported by over 50 years of use in various countries around the world, and no phytotoxicity was reported. It can be said.
[0026]
On the other hand, even if the need for preventive maintenance is known in the mind, the cost of 1.2 million yen to 3 million yen can be paid with the building owner at the stage where there is no visible damage such as red water or choro water. However, the burden is heavy and it is difficult to obtain cooperation from residents living in the building, so it tends to be left unimportant.
[0027]
For this reason, development of a cheap, safe and effective preventive maintenance method is strongly desired. The thin pipes that are prone to rust due to the loose flow of water have a thin steel pipe, so when red water begins to appear, more than half of the pipe is rusted. It may be as thin as paper, resulting in a limited life span. If the water supply pipe is corroded from the outside due to the intrusion of rainwater, it is necessary to rely on repairing cracks on the rooftop and outer walls and waterproofing construction covering the entire rooftop, but this must be done early and early. It's not a big burden.
[0028]
[Problems to be solved by the invention]
When using the rust preventive device in the water supply pipe that uses the rust preventive agent shown as the conventional technology as described above, all of the equipment cost, construction cost, consumables cost, and management cost are expensive. It is necessary to reduce it as a total or as a total. The main equipment cost is the chemical container fee and the dedicated stainless steel pipe attached to the container, and the main construction cost is the waterworks fee. In addition, the consumables cost is a medicine fee, and the management cost is a cost when the operation management of the facility is outsourced.
[0029]
The reason for the high cost of waterworks is as follows.
[0030]
The type and size of the receiving tank room and receiving tank designed at the stage of building the building are gusseted, and the pipe diameter used for the piping is determined by the size of the building, the instantaneous maximum amount of water used, etc. Since it is an individual design, what will be installed later must be an individual design that matches the existing equipment. In addition, it is not considered at the design stage to attach anything later to the water pipe of the water receiving tank, and since there is often only space for maintenance of existing equipment, drug containers are installed. The pipe must be pulled out to the place where it can be done, and the pipe after passing through the container must be put back again. Because of these, the work conditions are all different for each building, so first check the existing equipment and piping dimensions and piping route, etc., then check the location where the new equipment will be installed, the thickness of the piping to be drawn out, the joints used It is necessary to draw a schematic drawing by designing etc. Necessary parts will be gathered based on this drawing, but it cannot be said that pre-processing and assembling on-site will suffice.
[0031]
Since most water supply pipes are fastened with screws, removing unnecessary pipes and screwing in new pipes can make a difference of several millimeters just by turning one extra turn. If this slight difference is piled up, the tube that was to be fixed in contact with the wall will float 10 mm from the wall. Therefore, cutting and threading of new pipes are often performed at the site by matching the actual products, and it is often necessary to carry a set of processing equipment such as a cutting machine and a threading machine to the vehicle and transport them to the site.
[0032]
When existing piping is made in each direction of the XYZ axes, if a specific screw to be loosened is rusted, other screws may be loosened, and piping in other directions may be twisted. . Because of this and the small work space, at least two workers are required to carry out waterworks work. If safety managers and on-site supervisors are added to this, it will be affected by high labor cost levels. It will be.
[0033]
On the other hand, in the case of electrical work, it is sufficient that there is only one worker unless the installation board is too heavy or the work spans multiple floors. In addition, even if the situation at the work site changes each time, the thickness and length of the wires used will change slightly, so it is possible to respond flexibly in uniform work with tools that can be carried by hand. Therefore, the construction cost is not so high.
[0034]
The reason why the chemical container is expensive is that the container is arranged immediately after the pumping pump in which the backflow pressure of several tons of water is applied. In short, since it is only necessary to dissolve a rust preventive agent in the tap water supplied to each floor of the building, the effect will not change even if it is dissolved at the stage of the water receiving tank before being pressurized by the pump. If the medicine container is to be submerged in the water receiving tank, if the container is open so that many small holes are made and the solution can circulate with external water, pressure will not be applied to the container. A simple container with a processed pipe or the like is sufficient.
[0035]
In order to dissolve the drug by applying a water flow to the drug in the container, a separate dissolution pump is required, but there is no need for a powerful pump that pushes a large amount of water up to the roof of a high-rise building. It is only necessary to have one simple submersible pump that moves at a depth of about 2.5 m, and the price is not so high. Then, if a system in which these submersible pumps and simple containers are integrated is thrown into the water receiving tank and the power supply and control of the submersible pump is performed from the outside, no waterworks work is required.
[0036]
The expendable chemicals cause a chemical reaction with the rust on the inner wall of the water supply pipe, and have the function of decomposing and melting the rust and forming a film on the surface of the rust. In order for this chemical reaction to proceed sufficiently, it is necessary that the chemical solution and the rust of the iron pipe remain in contact for a certain period of time, and if the precious solution is passed through the iron pipe at a high speed, it is effective. Absent. From this point of view, the most effective method is to fill the water supply pipe with the solution at night when water is not used much and does not move.
[0037]
In the conventional technology, because of the structure of the equipment, the solution was always supplied when the faucet was twisted, so the solution was always supplied to cleaning, washing, car washing, garden watering, bath water, Moreover, since these waters pass through the iron pipe at a high speed, there was no time for chemical reaction against rust. In this case, it is natural that the cost of the drug as a consumables cost is high, and it is not so effective for the high cost, but overdose to the human body and a solution containing high nutrients is passed to the sewage The impact on the global environment is also a concern. So, if you can't expect any effect, it is possible to keep the drug consumption to less than half if you do not run the solution in the daytime but only in the evening to the night with the timer control. Environmental impacts can be mitigated. Regardless of the consumption of tap water, it is only necessary that the rust preventive device has the function of creating a solution with its own mechanism, and one dissolution pump is responsible for this important function.
[0038]
Management costs can be significantly reduced if it is not necessary to outsource the operation management of the equipment to an outside contractor. There are two reasons for this, because it is assumed that the operation management of the equipment attached to the building owned by the company is outsourced to an outside contractor. One is that there is a risk of leaking a large amount of water if the lid is not tightened firmly after filling the container in which high pressure is applied. This is because the supply of medicines at a slow cycle of once every two months is due to the lack of confidence in not forgetting, which can lead to serious damage.
[0039]
However, these concerns are based on conventional technology and are not unavoidable. First of all, regarding the case of water leakage, as long as the drug container is installed in the water receiving tank, even if the container breaks, there is no possibility of water leakage. In addition, as long as the medicine container is submerged in the water receiving tank, the remaining amount of the rust preventive drug must be detected and displayed externally. If the remaining amount can be displayed, the remaining amount is zero. It is fully possible to issue an out-of-drug alarm signal when Accordingly, it is not necessary to entrust the operation management of the equipment to an outside contractor unless neglected to respond when an alarm signal is issued. These are the basic concepts of the apparatus according to the present invention.
[0040]
On the other hand, if the basic method is completely changed from the conventional method, the problem to be solved by the invention is also changed, and it is not enough to improve the drawbacks of the conventional technology, and a new problem is generated. It will be. Given the basic concept described above, the problems to be solved by the invention are as follows. First, the problem is how to easily replenish a rust preventive agent into a container submerged in a water receiving tank. Second, there is a problem of how to display the remaining amount of the rust preventive agent without lifting the heavy device from the water. The third problem is how to supply a solution having a specified concentration when necessary and fill the water supply pipe at night. The fourth problem is how to suppress the amount of phosphorus that is likely to be excessively absorbed by the human body. Fifth, there is a problem of how to detect an out-of-drug and issue an alarm to a manager who works or resides in a building. Sixth, there is a problem of how to relay a signal when an alarm signal does not reach one set of transceivers. Finally, when the alarm starts to sound at night or during the visitor, how to stop the alarm and forget to replenish the medicine.
[0041]
When all of these various problems have been solved at a certain level or higher, owners of many buildings that have passed the age of construction apply for the purchase and installation of this equipment, and the equipment supplier supplies submersible pumps, electrical and electronic components, Orders for switchboards, rust prevention chemicals, etc. will be placed at various locations, and new work will be generated for equipment distributors, producers, electrical contractors, etc., thus contributing to industrial development.
[0042]
Therefore, the present invention is able to introduce the apparatus with low equipment costs and construction costs, suppresses the running cost and the influence on the human body, and prevents self-management from causing adverse effects due to idle operation etc. The purpose is to provide.
[0043]
[Means for Solving the Problems]
  In order to achieve the above object, a water pipe rust preventive device according to the present invention temporarily stores water that can be used in daily life, and this water operates a first pump through the water pipe. Receiving water tanks supplied to multiple locations,A drop lid that is installed in the water receiving tank and stores a water-soluble solid rust preventive agent and is placed on the stored rust preventive agent and moves downward as the rust preventive agent decreases. A medicine container provided on the side surface with a hole that allows water to enter and exit from the water receiving tank, and an opening provided in the medicine container, and is installed to directly feed water into the medicine container. The rust preventive agent is dissolved in water by stirring to form a solution of the rust preventive agent, and a solution for supplying the solution of the rust preventive agent into the water receiving tank from the hole of the drug container. And at least a rust preventive drug remaining amount detecting device for detecting the remaining amount of the rust preventive drug by detecting the position of the drop lid.
Here, the remaining amount detecting device includes a magnet provided on the drop lid, a plurality of reed switches juxtaposed in the vertical direction, and a plurality of LEDs turned on and off by the plurality of reed switches. Is preferred.
In addition, the time zone for supplying the rust preventive chemical solution is defined by controlling the operation and stop of the second pump, and the rust preventive chemical solution is supplied when the rust preventive chemical solution is supplied. It is preferable to provide a timer for controlling the concentration of the drug solution by controlling the operation time zone of the second pump.
[0044]
More specifically, an underwater pump that dissolves the rust preventive agent and allows the dissolved fine drug powder to flow horizontally without being deposited on the bottom of the water receiving tank, and the remaining amount of the agent is detected. To make it easier to lift, a drop lid with a magnet that is joined by a rope, a plurality of reed switches that detect the position of the drop lid, a sensor cylinder filled with plastic to make a watertight structure, and a water tank chamber A device that is placed in the main control panel installed on the wall and displays the remaining amount in the drug container; With the remaining capacity of the submersible pump that dissolves the drug, the water flow branching device and the branch water flow control valve that stirs and refluxes the bottom of the water receiving tank, and when the dropping lid falls to the emergency refill point, it easily becomes common external noise. Identify A device that emits a warning signal, a signal transmission device that informs the building manager of a warning signal for emergency drug replenishment at a remote location in the same building, and a building manager that uses a single means of warning signal Signal relay device for connecting a plurality of transmission means, a light receiving element or a small microphone for detecting light and sound generated by the operation of the n-th receiver, and a binding for fixing and connecting these to the receiver A fixing device such as a band, a pseudo battery that supplies power for operating the (n + 1) -th stage transmitter, and a fixing device such as a binding band that locks the signal transmission button of the transmitter in advance, and a solution are supplied. A 24-hour timer that controls the operation / stop of the submersible pump by specifying the time zone, and controls the concentration of the solution according to the operating time, and power control that finely adjusts the solution concentration by controlling the rotation speed of the submersible pump It is characterized in that it is composed of a location.
[0045]
With this structure, if the average resident dinner time zone of the building resident is 19: 30-20: 30 and the dinner wash ends at 21:00, dinner preparations are made. Until 19:30, the rust preventive solution is not supplied to the faucet, and by 21:00 or by bedtime, a solution close to the specified concentration of 5 ppm is supplied to the faucet to fill the water supply pipe. It is possible to control to determine the operation start time of the chemical dissolution pump by calculating the time lag that the water in the water receiving tank reaches the faucet.
[0046]
Then, after 21:00, it is possible to switch to intermittent operation of about 15 minutes per hour, maintain the solution concentration of 5 ppm in the water supply pipe, and control to end the operation of the pump at 24:00.
[0047]
As a result, the water used for eating and drinking in the morning was used up to 2-4 liters that had been stored in the refrigerator by 19:30 the day before and was used to fill the night water supply pipe. The solution can be used for cleaning, washing, garden watering, bath water, etc.
[0048]
In addition, when going home late at night and preparing dinner after 21:00, 5-6 liters of tap water filled in the daytime water supply pipe should be reserved for direct eating and drinking. That's fine.
[0049]
In addition, if there is a water supply pipe that is not used every day due to a 24-hour bath, etc., about 2 cups of water are pumped out before going to bed after 21:00, and the inside of the water supply pipe is filled with a solution of an anticorrosive agent. It only has to be satisfied.
[0050]
If the situation differs depending on the building, it can be dealt with by referring to the above-mentioned standard operation form and changing the setting of the timer by the building administrator to find the optimum operation time.
[0051]
On the other hand, when a drug out alarm starts to sound at night or during a visitor, the alarm can be unplugged from the outlet and moved to a prominent place such as the entrance or study.
[0052]
Since the water tank of a building needs to be cleaned approximately once a year, there is always a doorway for people to enter and exit, no matter how small the water tank is. The water receiving tank is usually a large box-type container installed indoors, and the entrance / exit cover provided at the top of this container is not a person on top of it, nor is a vehicle passing through it. Most cases are made of a light cylindrical lid made of plastic rather than a heavy one. Therefore, it is easy to lift up the cylindrical lid, pull up the drop lid anchored by the rope from the drug container protruding from the water surface directly below, and replenish the drug. After the medicine is replenished and the drop lid is placed on the top of the medicine, if the reset switch on the main control panel is pressed, the emergency refill alarm signal transmission is canceled and the control circuit is set to the initial state. Accordingly, there is no need for complicated operations such as opening and closing a plurality of valves, and even an amateur can easily operate.
[0053]
The anti-corrosive agent for water supply “Sirifos” is a colorless, tasteless, odorless, translucent, hardly soluble solid, and its pH value is not different from that of tap water, so it is very difficult to detect the presence or absence thereof. Therefore, a method devised to display the remaining amount of medicine in the container and issue an alarm signal at the emergency replenishment point, put the medicine in an upright cylindrical medicine container, place a cylindrical drop lid filled with magnets, It is intended to detect the position of a drop lid that falls with wear with a sensor cylinder with a large number of reed switches attached to the side or center of the drug container. The remaining amount of the medicine is detected step by step depending on which reed switch has entered the magnet and the lid is responsive, and can be confirmed with a medicine remaining amount indicator installed in the control panel. If the medicine is appropriately replenished by looking at this indicator during the regular patrol, the emergency replenishment alarm signal is less likely to be rushed. Also, if the reed switch at the final stage for outputting an alarm signal is installed at a position slightly higher than the bottom, it is possible to maintain a safety stock until replenishment is performed.
[0054]
Needless to say, the water pipe rust preventive agent is a chemical, and therefore it is necessary to cause a chemical reaction by contacting the rust in the water pipe for a long time. From this point of view, even if the solution is run during the daytime when water is used frequently, it is not very effective, and it is better to fill the water supply pipe with a solution having a concentration just below the specified concentration at night when there is little movement.
[0055]
However, there is a long pipe between the water receiving tank where the solution is made and the faucet of the house or office, and the solution will not flow unless the water in the pipe is consumed. It is unexpectedly difficult to supply the solution to the faucet in a timely manner until the last use of water.
[0056]
Therefore, in the present invention, attention is paid to the fact that there is a time of about 1 hour from the end of the dinner preparation to the end of the clean-up cleaning, and during this time, the solution starts to come out of the faucet. Since a lot of water is used even after the washing is over, the solution supplied at this stage does not have to be so concentrated, and continues to replenish the water used after that with a certain concentration of concentrated solution. It is taking shape.
[0057]
When there is an administrator room for the purpose of monitoring suspicious persons entering and leaving the building and responding to visitors, it is usually installed on the first floor. On the other hand, a receiving tank that receives supply of city water is often provided on the first floor or the first basement floor because of water pressure. In such a general case, since the distance from the water tank room to the manager room is short, the medicine out warning signal is managed by a signal transmitter / receiver using radio waves or a set of carrier transmitter / receiver using an AC line. There are many cases that can reach the human room.
[0058]
However, in buildings and small buildings mainly composed of stores, there is often no manager room, and even if there is a manager room, there are many cases where managers are not full-time. In such a case, the actual manager may be the owner of the building that lives on the top floor or the management union director who lives on the higher floor. On the other hand, transceivers using radio waves often reach only about the 4th floor in the vertical direction within a building even if the radio waves reach up to about 100 m at a visible distance. This is because the rebars are laid like a mesh on the concrete floor, blocking the radio waves. The carrier wave transmitter / receiver using the AC line may reach up to the 10th floor depending on conditions, but this is also limited, and there is a restriction that it can reach only within the jurisdiction range of one integrating wattmeter. Since it is not allowed to increase the intensity of the radio wave, in such a case, it is necessary to connect a plurality of sets of transmitters / receivers by a relay device and relay and transmit signals.
[0059]
In the present invention, using a repeater having a function of discriminating between normal signals and noise, a plurality of sets of various transceivers are connected so that signals can be transmitted to higher floors. Transmitters and receivers that transmit signals from remote locations always have a function that emits a audible alarm, and some LEDs turn on when the receiver is activated. Can detect the operation of the receiver. In addition, the latter transmitters that should relay the signal are mostly push button type powered by dry batteries, so lock the push button in advance by tying the push button with a binding band and replace the dry batteries. A signal can be transmitted by supplying power through a pseudo battery inserted in the battery. If this procedure is repeated several times, in principle, signals can be transmitted to the top floor of a skyscraper.
[0060]
A pseudo battery is one in which an electrode is attached to a plastic rod having the same diameter and size as the original battery and power is supplied from the outside of the device. This is a result of considering that an end user can connect an arbitrary transceiver without modifying a commercially available transceiver. However, in some transmitters of some manufacturers, if the transmission button is locked ON, there is a case where transmission is not performed even if power is supplied later. If this type of transmitter / receiver cannot be connected, or if you really want to connect it, you must always connect the main power supply and take measures to short-circuit the send button at the relay contacts etc. Therefore, it is necessary to add a circuit.
[0061]

A fifth embodiment which is installed and operated outside will be described with reference to the drawings.
[0062]
First, a first embodiment will be described based on FIGS. 2, 3, 4, and 5. FIG.
[0063]
FIG. 2 shows an outline of the positional relationship between the apparatus submerged in the water receiving tank, the water receiving tank water surface, and the water receiving tank entrance. When the water tank inlet / outlet lid 106 is removed, an open type drug container 223 appears immediately below, so the drop lid locking cord 227 connected to the drop lid 225 is pulled to raise the drop lid. Thereafter, a spherical solid medicine is put in, a drop lid is put on, the main control panel 210 is turned on, and the reset switch is pressed. In this way, the medicine remaining amount indicator in the main control panel displays the remaining amount full, and when the time specified in advance by the timer comes, the submersible pump 222 starts rotating, blowing up a strong water flow, The solution is ejected laterally from the drilled hole. On the other hand, the remaining water flow of the pump flows through the bottom of the water receiving tank by opening and subtracting the branch water flow rate adjusting valve 224 and adjusting the jetting direction of the branch water flow, and the solution is refluxed at the bottom of the water receiving tank, thereby producing a concentrated solution.
[0064]
When the medicine is exhausted, the drop lid 225 is gradually dropped due to the gravity due to the internal weight, and is attached to the center of the container when the inner diameter of the medicine container is large, and to the side of the container when the medicine container is thin. The plurality of reed switches arranged in the sensor cylinder 226 sequentially react and transmit the result to the master control panel 210 through the signal cable 229, whereby the remaining amount of the medicine is displayed on the display in the master control panel. Is displayed.
[0065]
FIG. 3 explains in detail the relationship among the open-type medicine container 223, the rust prevention medicine 312, the drop lid 225, and the sensor cylinder 226. A joint 314 is fixed to the bottom of the medicine container with a screw, and a medicine fall prevention net 311 is press-fitted into the joint 314, so that the medicine remains in the submersible pump 222 even when the rust prevention medicine 312 is introduced. There is no such thing as falling down. Now, when the medicine is put in a full container and the drop lid 225 is placed thereon, the drop lid 225 and the first stage of the reed switch 341 are in the positional relationship as shown in the figure, and the magnet 322 in the drop lid affects the reed switch. There is nothing. The drop lid and the sensor cylinder are filled with a waterproof mold resin for forming a waterproof structure and are hardened, so that they are not affected even if they are covered with water. When a strong water flow is applied from below in the figure by the submersible pump, the water flow scrapes off the surface of the rust preventive agent 312 and the solution is ejected laterally from the solution discharge hole 313. Although it is a thin solution at first, the jetted solution is again sucked into the submersible pump and sprayed onto the medicine, so that the solution becomes gradually thicker.
[0066]
This solution is supplied into the water supply pipe to prevent rust, but if this treatment is repeated for a long period of time, the solid sphere of the rust preventive agent 312 becomes gradually smaller. On the other hand, since the drop lid 225 has a built-in iron weight 321, the drop lid 225 gradually falls downward as the medicine is consumed. When this approaches the reed switch, the reed switch circuit is closed by the magnetic force of the magnet 322, and an electrical signal is sent to the master control panel through this closed circuit. Each of the five reed switches shown in FIG. 3 is grounded separately, and the LED corresponding to each reed switch blinks so that the remaining amount of medicine can be identified. The reed switch at the final stage is connected to a special circuit for issuing a medicine out alarm, and when the medicine is low and the lid is dropped to this position, an emergency medicine replenishment alarm is issued.
[0067]
When the drop lid is dropped down, it is difficult to take out the drop lid. Therefore, the drop lid is tied to the drug container by the drop lid anchoring cable 227 and the anchoring cable tying bands 331 and 333. The rope 227 may be pulled up.
[0068]
FIG. 4 shows how to connect an electric / electronic circuit in the main control panel and a communication device for transmitting a medicine out alarm signal. When the power switch 411 in the master control panel power supply unit 410 is turned ON, the pump operation control unit 420, the DC power supply for the control circuit, and the alarm signal output power supply are energized. A 24-hour timer 421 is connected to the pump operation control unit, and can be arbitrarily designated ON / OFF several tens of times a day in about 15 minutes. Further, a power controller 422 is connected to the subsequent stage so that the rotation speed of the submersible pump 222 for dissolving and refluxing the drug can be controlled. This adjusts the chemical | medical agent density | concentration at the time of submersible pump driving | operation with the valve | bulb 224 for branch water flow rate adjustment.
[0069]
Initially, when the medicine is filled in a full container, the magnet built in the drop lid in the form shown in FIG. 3 has no effect on the reed switch. When the reset switch 431 shown in FIG. 4 is pressed in this state, a direct current flows through the resistor R1 and the diodes D1 to D5 and flows into the gates of the thyristors SR1 to SR5, thereby triggering each thyristor. The anodes of these thyristors are connected to LE1 to LE5, which are LEDs for displaying the remaining amount of medicine connected to the power source, respectively, and the reed switches RS1 to RS5 connected to the anode are all in an open state. All triggered thyristors are turned on, and LE1 to LE5 are all lit to indicate that the remaining amount of medicine is full.
[0070]
At this time, since the voltage divided by the internal resistance of SR5 and LE5 is applied to the base of the transistor Tr1 of the alarm signal holding unit 450, the collector voltage is close to 0V, and the thyristor SR6 is OFF. Since the NC contact of the reset switch 431 supplies driving power to the alarm signal holding unit 450 and the intermittent power supply unit 460, even if these circuits are activated, the reset switch is pressed to drive the NC contact. Since all power is cut off, these circuits stop operating and return to the OFF state.
[0071]
When the time programmed in the 24-hour timer 421 comes and the submersible pump 222 is activated, a strong water flow is applied to the rust preventive drug 312 in the open drug container 223, and the drug is dissolved little by little. A solution will be created. If this is repeated every day, the spherical solid medicine will gradually become smaller, but since the drop lid 225 with a built-in weight and magnet is placed on the top of the medicine, the drop lid 225 will fall little by little due to gravity. Then, it approaches the uppermost reed switch RS1 and turns it on. As a result, the anode of SR1 is short-circuited to the ground. At this time, the reset switch is turned off and no trigger signal is applied to the gate, so SR1 is turned off.
[0072]
While the reed switch RS1 is in the ON state by the magnet, a current flows through the LE1 through the RS1, so the LE1 continues to be lit, but the drop lid eventually falls further to turn off the RS1, so at that time the LE1 Indicates that the remaining amount of the medicine has been reduced by 1/5. Similarly, the lights up to LE5 are sequentially turned off, and the consumption of the remaining amount of medicine is displayed. However, a slightly different movement starts when the last-stage reed switch RS5 is turned on. Since RS5 drops the base of Tr1 to the ground together with the anode of thyristor SR5, the state where the collector and the emitter have been short-circuited until then is released, and a trigger current flows into the gate of thyristor SR6 through diode D6. At this time, since the current flows through the NC contact of the reset switch 431 to the multivibrator connected to the anode of SR6, SR6 is turned ON, and thereafter, the magnet of the drop lid is separated from the reed switch RS5. The self-holding is continued and the alarm signal is continuously transmitted.
[0073]
On the other hand, when SR6 is turned on, the capacitor C1 is charged by the resistor, and during this time, the alarm buzzer 461 and the phototriac PT1 are turned on by the current flowing through the transistor Tr2. When the voltage of C1 gradually rises and reaches a voltage determined by the voltage dividing ratio of the resistor connected to the PUT, the PUT is turned on to discharge the charge accumulated in the capacitor C1 and connected to the cathode side of the PUT. The current flowing through the alarm buzzer 461 and PT1 is cut off by reversely biasing the base and emitter of Tr2 for a time determined by the resistance value and the capacitance of C1. When the charge of C1 is completely discharged, the PUT is turned off and returns to the initial state. Since this is repeated, the circuit based on this PUT functions as a multivibrator. In the embodiment, ON / OFF is repeated at intervals of about 20 seconds. The photo triac PT1 is connected with a triac capable of flowing a large current, and this controls the energization and shut-off of the AC 100V from the main control panel power supply unit 410. Therefore, the alarm signal output power outlet 463 has an AC power supply. Will be supplied intermittently.
[0074]
Therefore, if a buzzer or red light that operates at 100 VAC is connected to this outlet and the wiring is extended to a place immediately noticed by the building manager, it is possible to automatically report that the rust preventive device has run out of chemicals. On the other hand, in a building unlike a wooden house, it is not easy to route the wiring over a long distance, especially when the floor of the water tank room and the manager room are different, it is impossible to route the wiring. It will be close to. In preparation for such a case, the main control panel according to the present invention can incorporate a carrier wave transmitter using an AC line or a radio wave transmitter for transmitting a weak radio wave.
[0075]
In the first embodiment, after connecting a desk lamp in place of a red lamp and confirming blinking, a commercially available remote bell that carries a signal through an AC power line was connected. Since this device has a mechanism for locking signal transmission on the transmitter side, the receiver connected to the same power line can be simply plugged into an AC power supply outlet with the switch locked to ON. Can be operated to turn on the LED and sound an alarm.
[0076]
Fig. 5 shows a circuit in which an alarm signal power supply / disconnection device installed on the master control panel is connected to a carrier wave transmitter using an AC line, which can transmit an alarm signal from the first floor to the fifth floor. It was. However, the signal transmission range is limited to the management area of the integrating wattmeters installed in each home, etc., and only a very weak signal is carried so as not to adversely affect other devices. When other equipment (charger, computer, AV equipment, etc.) is connected to the outlet, the receiver may not operate, and it is necessary to select an appropriate outlet within the signal reach.
[0077]
Next, a second embodiment will be described based on FIG.
[0078]
In the second embodiment, various commercially available remote bells that transmit weak radio waves permitted by the Radio Law are selected and connected. An AC adapter is connected to an AC power output outlet of the master control panel, and DC power converted thereby is supplied as power for the radio wave transmitter. There are two types of radio wave transmitters to be connected at this time. Some types transmit radio waves when a signal transmission switch is secured in advance and power is supplied, and others do not. In the former case, connection can be made without modification by using a pseudo battery, but in the latter case, a photocoupler or relay contact is connected to the electronic circuit of the transmission switch, or power is applied by a resistor or capacitor. You have to adjust the timing. The radio wave transmitter that was first connected in the second embodiment happened to be the latter form, so that the connection in the circuit shown in FIG. 6 was made, and wiring was inevitably added. Later, when the former type radio wave transmitter was connected, the signal transmission button was secured with a binding band in advance and always turned on, and the DC power was supplied via a pseudo battery. .
[0079]
Although equipment using dry batteries as a power source on the receiver side was also found, the device according to the present invention monitors the out-of-drug for over a decade or more until the building is demolished. Since it was necessary to be able to send and receive signals at any time, we chose not to use batteries that automatically discharged over time and used up their lifetime. However, no radio wave transmitter using an AC power source is found on the transmitter side, and all of them are of the dry cell type. Since this transmitter must be able to guarantee reliable operation for a long period of use, we took measures to remove the dry battery, insert a pseudo battery, and supply power using a general-purpose AC adapter. . From this point of view, even if the receiver side is of a dry cell type, it is only necessary to increase the number of AC adapters and supply power via a pseudo battery, and this is not impossible.
[0080]
Generally, in this type of equipment, when the voltage at the dry battery is 3V, for example, it should be made to operate even when the voltage drops to about 2V. In this case, since the IC or the like used should be based on C-MOS instead of TTL, it can be considered that it corresponds to a wide range of voltages from about 1.5V to 12V. Therefore, as a result of dealing with a 3V transmitter and a 4.5V transmitter with a 5V AC adapter, there is no particular difference from the operation with a dry cell, and operation over a long period of time. No abnormalities occurred during the test.
[0081]
In the building, the number of floors in which the radio waves reach in the vertical direction is the highest class, where radio waves can reach up to 100 meters at a visible distance. There was no particular difference in performance even when the distance was 40 m. In this respect, the carrier wave transmitter / receiver using the AC line is stronger in the vertical direction, and the signal reaches a distance about twice that of the radio wave transmitter / receiver depending on the environmental conditions of the building. This may be due to the signal being transmitted through the FC cable for the AC line arranged in the wall of the building. Therefore, it is a good idea to effectively use the carrier wave transmitter / receiver utilizing the AC line in order to reach the high-level floor of the medicine out warning signal.
[0082]
On the other hand, among the transceivers using radio waves, there are devices in which the receiver continuously sounds a chime when the transmission button is continuously pressed, and there is a device that responds only once even if the transmission button is continuously pressed. Depending on the setting of the selection button, “one time” means that the chime is sounded once or three times, and there is no “continuous” option. Because situations that require emergency drug replenishment may occur at night or when you are out of the office, even if you refill the drug after the next day, someone will notice and take some action. The alarm must continue to sound until it is taken. Therefore, something that stops and chimes three times while you are away cannot achieve the intended purpose. In order to cope with such a situation, the electronic control circuit according to the present invention does not continue to supply power to the transmitter when the medicine needs to be replenished urgently. Thus, the transmitter is turned on / off. As a result, the building manager can select a means for transmitting a signal from a wider range, and can reliably receive the alarm signal. Determining whether or not the device can be connected is not difficult if the operation test is carried out at the store where the device is sold, and if the receiver operates by inserting and removing the dry battery while holding down the send button. Connectable.
[0083]
Furthermore, a third embodiment will be described based on FIGS. 7, 8, and 9. FIG.
[0084]
The carrier signal through the AC line can only reach within the range of the same integrated wattmeter, and the signal by radio waves reaches only about 4 floors in the building floor, so the building manager or owner is the same as the water tank room Attempts were made to deal with cases where the place does not meet any of these conditions while working or living in the building. Regardless of whether the carrier wave uses an AC line or a radio wave, it is out of the question to increase the strength of the transmitted signal. In either case, it is a violation of various laws and regulations, and there is a great risk of adverse effects on computers, AV equipment, etc. installed in the same building. .
[0085]
Therefore, we made a prototype of a repeater that connects several types of remote bells with one set of transmitter and receiver to extend the signal transmission distance. An example is shown in FIG. The various types of remote bells that are on the market carry signals from a distance, so they are designed to produce a fairly loud sound so that the signal recipients will immediately notice, and from multiple transmitters It is also necessary to change the timbre in order to identify the signal, so speakers are usually connected. Some of them turn on the LED or flash strong light along with the sound from the speaker. In order to operate these sound and light signal sources with a strength that humans can be surely aware of, it is necessary to supply a certain amount of power, and since a drive circuit is normally configured by transistors, signals such as photocouplers and relays are required. It is also possible to connect transmission parts. Therefore, if the input side of the photocoupler is connected to the signal source drive circuit located at the end of the transmitter / receiver that transmits the alarm signal, the output side is connected to the signal transmission switch of the transmitter / receiver in the next stage. An alarm signal can be transmitted by relay between a plurality of transceiver systems. If this relay is repeated, an alarm signal can be transmitted to a remote place in the same building within a weak signal range that does not affect others. However, if this type of multi-stage connection is used, the stability of the system will deteriorate, and it will be easy to cause malfunctions by picking up external noise. In the experiment of the embodiment, this tendency also appears. Therefore, a capacitor is inserted on the input side of the photocoupler to absorb and remove external noise for a short time. In anticipation of this, the normal alarm signal is assumed to be longer than 10 seconds as described above. This out-of-drug automatic alarm system is very convenient, and you don't have to feel the heavy burden of operating a critical system that affects the life of your building.
[0086]
Now, in the method of connecting a plurality of transmission / reception systems listed in the previous section, the drive circuit for the actuator for output signal, which is inherently possessed by the carrier wave transmitter / receiver or the radio wave transmitter / receiver, is utilized. Commercial devices used in the embodiment are generally called “remote bells” and are devices that have the purpose of transmitting some signal from a remote location. There was always a function to arouse. Therefore, using the drive circuit, which is indispensable for realizing these functions, was a natural treatment, but there are cases where the drive circuit attached to the communication device cannot be used for some reason. I have to think about it. In such a case, there is no method other than automatically detecting the alarm sound or flashing light that is the original function of the “remote bell” and transmitting it to the transmitter at the next stage. In such a case, if a audible alarm is picked up by a microphone, or if blinking of light is detected by a CdS light receiving element, the signal will be much smaller than the signal flowing in the drive circuit, and ambient noise will be generated. It must be prepared that it will be difficult to distinguish it from noise caused by external light. Therefore, as a part of the embodiment, it was confirmed that it was possible to cope with such a case.
[0087]
FIG. 8 detects and amplifies the alarm sound with a small microphone and activates the relay, and FIG. 9 detects and amplifies the blinking of the LED and the change in emission color, and similarly activates the relay. In either case, it is necessary to eliminate malfunctions due to external noise, and it is necessary to devise such that the relay side remains on for a certain period of time even if the sound level or light flashes. This is because it is difficult to discriminate noise from signals that are repeatedly turned on and off in a short time when a transceiver is additionally connected at a later stage.
[0088]
FIG. 8 shows a case where sound is detected and relayed by an ultra-small microphone 821 that is closely fixed to the front surface of the speaker 811 of the receiver 810 in the previous stage. After the signal level is adjusted by the variable resistor VR1, the capacitor C1 is connected. The passing AC signal is amplified by transistors Tr1 and Tr2. When this amplified signal is applied to the base of the transistor Tr3 for driving the relay through the resistor R1, an electrolytic capacitor C2 for absorbing noise is connected, so that this capacitor absorbs noise for a short time of about 0.2 seconds. Then it does not work. If the regular signal sound is a series of short sounds, the first 2 to 3 pulses are treated as noise, but when the capacitor is charged and the potential rises, no more is absorbed and the normal pulse is It is treated as a signal sound. In most cases, noise is generated at short intervals in a discontinuous manner, so that the electric charge stored in the capacitor is also spontaneously discharged and no malfunction occurs. Also, because it was stored in the box of the repeater, it was hardly possible to pick up external sound as noise from the microminiature microphone 821.
[0089]
When Tr3 is turned ON by a normal signal sound and the relay RL1 is activated, the charge of the capacitor C3 that has been charged through the NC contact is applied to the base of the Tr3 through the NO contact and the resistor R2, and at the time of C3 and R2. The relay self-holds for about 20 seconds by a constant. If the signal transmission switch 831 of the transmitter at the next stage is tied in advance with a binding band or the like, and power is supplied through the pseudo battery 832, a regular signal can be automatically relayed.
[0090]
FIG. 9 is a diagram in which light is detected and relayed by a light receiving element 921 that is closely fixed to the front surface of the light emission signal source 911 of the receiver 910 in the preceding stage. Since the resistance value of the light receiving element 921 varies greatly between when the LED of the receiver at the previous stage is turned on and when it is turned off, initially, an experiment was performed with a simple circuit of about two-stage amplification of the transistor. The circuit was unexpectedly complicated. The variable resistor VR1 and the Zener diode ZD make a light / dark reference, and the input signal is compared with this to determine whether the operational amplifier OP1 is ON / OFF, and OP2 / OP3 amplifies the signal to drive the relay. The transistor TR1 is controlled. Noise absorption and self-holding for a fixed time are the same as in FIG.
[0091]
8 and 9, DC power is supplied to the pseudo battery. However, as long as the relay contacts are used, it is easy to supply AC power to the transmitter in the next stage. There is no problem even if it is a carrier transceiver using an AC line. However, in that case, the AC power supplied to the transmitter must be within the jurisdiction of the integrating wattmeter that has jurisdiction over the power source in which the receiver is installed.
[0092]
In principle, the pseudo battery is the same as connecting the output of the AC adapter with a crocodile clip instead of the battery, but it does not know when the crocodile clip will come off, so it can be used for an alarm device, etc. Because it is inappropriate, it is designed to fit in the existing battery box even if it takes a lot of trouble. When a plastic round bar with the same thickness as a dry cell is cut to the same length as the dry cell and inserted into the battery box, it is firmly fixed by the power of the battery spring. It becomes a permanent power supply that cannot be easily removed.
[0093]
8 and 9, a relay is used to make the circuit easy to understand. However, if you want to reduce the size and power consumption, use a photocoupler or phototriac instead of a relay and replace the transistor or triac. A circuit that performs the same function can be configured by using both of them.
[0094]
Since the AC line carrier wave receiver connected in the first embodiment was provided with both a speaker sounding and LED lighting, the repeater shown in FIGS. As a result of connecting various types of radio wave transmitters to those outputs, all worked without problems. However, the transmitter connected to the output side of the repeater must not operate the receiver on the input side by the signal output. Some commercially available devices can switch between three or more channels at the output frequency. This is important when multistage connection is used. Different communication device manufacturers usually have different signal frequencies, so when using a communication device with only one channel, it is also possible to connect communication devices from different manufacturers. The input signal of the repeater may be sound or light, and it does not matter whether it is a continuous signal or only an intermittent signal.
[0095]
In addition, the repeater is designed to output DC power, but if the relay wiring is changed, AC power can also be output, so a receiver that emits sound or light and a transmitter that operates with DC or AC are free. Can be connected to. As a result, it was confirmed that many combinations of transceivers could be connected to transmit alarm signals to long distances in the building.
[0096]
As described above, the circuits shown in FIGS. 8 and 9 have a function of absorbing noise. However, there are various types of noise, and some of them are rarely possible in ordinary residential buildings. May be mixed. For example, it may be a case where lightning has fallen nearby, or night work has been carried out in the vicinity, and a night light switch that consumes a large amount of power is turned on or off. In fact, when a welder was used near a repeater, an alarm sound could be heard. Trying to cut this kind of exceptional noise can make your circuit extremely complex and completely eliminate the possibility of false alarms with unexpected noise. I can't do it. Fortunately, if an alarm is issued due to abnormal noise that cannot be completely removed by the noise filter, the alarm sound automatically stops when the noise disappears. On the other hand, a regular alarm signal will never stop unless some action is taken on the receiver or transmitter, so if an alarm sounds but it stops for a short time, You can think of it as a false alarm due to special noise.
[0097]
In the fourth embodiment, a set of devices according to the present invention is attached to an existing building and operated for about three months to confirm the operation of the entire system and determine the standard operation method. is there. The observed phenomena and the hypothesized matters are as follows.
[0098]
(1) When waiting for some visible abnormality to appear, it was discovered that faint red water came out from the water supply faucet of the 24-hour bath, the least frequently used.
[0099]
(2) It was 5 ppm when the density | concentration of the total iron contained in the water supply at this time was measured. Therefore, preventive maintenance measures should be taken when the total iron concentration reaches at least 5 ppm.
[0100]
(3) Immediately after the discovery of red water, the operation of the rust preventive device in the water supply pipe according to the present invention was started, and it completely disappeared in 3 months. Since then, there has been no recurrence.
[0101]
(4) It takes an unexpected amount of time to adjust the concentration of the lower half of the water in the water receiving tank to 5 ppm, and when the solution starts to be used, the consumption speed is high and the concentration is difficult to increase.
[0102]
(5) According to the measured individual data, the bath water is 200 liters, the washing machine is used 60 liters once, and the toilet tank is 10 liters per serving.
[0103]
(6) The amount of water used for direct eating and drinking is around 2 liters for breakfast, 2 liters for lunch, and 4 liters for dinner. The amount of water used to wash vegetables and fish is estimated to be about twice that of each.
[0104]
(7) As a result of actually measuring the amount of water used for the dinner washing, it was 36 liters. Backcounting from the ratio of time required for meal preparation, the amount of water required for breakfast and lunch washing is about 18 liters each.
[0105]
(8) The amount of water used at night is unexpectedly large. About 60 liters of water is used by a family of four, and dishes such as tea cakes and fruits are often washed again. It seems that most of the water used in toilet tanks is occupied.
[0106]
(9) The amount of water stored in the water supply pipe is important in designing the standard operation method. The variation is large, but 20 liters for a thin tube dedicated to each household, 20 liters per household with a common thick tube, and a total of 40 liters is considered standard.
[0107]
In addition to these, although it is fragmentary, based on the average value of various collected actual measurement data, etc., the standard operation time of the dissolution pump is 17:00 to 22:00, and then intermittent operation every 15 minutes for 1 hour. We decided to continue until 2am. The original idea was to create a 5ppm solution in a short time just before the dinner washes were finished, and when the wash was over and the faucet was closed, it was intended that the narrow water pipe was completely filled with the required solution. However, this is because various investigations and experiments according to the fourth embodiment have revealed that this is not always necessary. However, it is necessary to accumulate more actual measurement data to find a more appropriate standard operating time.
[0108]
If you use 60 liters of water at night and have another wash, it is enough that the solution reaches the middle of the thin tube at the end of the dinner wash, and the concentration reaches 5 ppm. There is no need. There is no harm to the solution being delivered during the wash because it is too early to reach, and it is unlikely that 20 liters of water will be used for dinner. Absent. Therefore, rather than making the pump powerful and expensive, it was a form that slowly took time to make a medium concentration solution from the time of going out for dinner, and replenished the water solution used at night with a thick solution. It is. This has the effect that even if multiple residents have dinner at different times, a wide range of responses can be taken.
[0109]
FIG. 10 schematically shows the amount of medicine taken into the human body when a solution with a constant concentration is always supplied from a water supply pipe according to the conventional technique. It should be noted that the amount corresponding to the area filled with black is the standard that has been regarded as “safe” in the past.
[0110]
FIG. 11 shows the transition of the concentration of the solution supplied from the faucet and the amount of medicine taken into the human body when the water supply according to the present invention is performed and the water supply is used as usual. The water coming out of the faucet at breakfast is a 5ppm solution, and it is a busy time, so it is difficult to take time to fill the bath water or turn the washing machine. Therefore, 2 liters for direct eating and drinking can be either drawn in the afternoon of the previous day and stored in the refrigerator, or if it is about 0.5 liters per person, the harm can be ignored. For those who do not want to spend a lot of time. Even if harm is ignored, the amount of medicine taken into the human body is 1/3 of the amount that has been considered safe in the past. In the figure, the reason why the minimum value of the faucet concentration does not fall below 0.5 ppm is that a thin solution diffused in the water receiving tank or the water supply pipe remains, and is based on an actual measurement value.
[0111]
FIG. 12 shows the transition of the solution concentration of the water supplied from the faucet and the amount of medicine taken into the human body when the water supply according to the present invention is used and the afternoon water supply is used for breakfast preparation. . The intake of the drug to the human body will be reduced to about 1/10 of the standard that has been regarded as safe.
[0112]
When a warning sound is sent from the receiver prompting an emergency replenishment of a drug at night or during a visitor, it may not be possible to immediately go to the replenishment, nor does it have to be replenished so quickly. In such a case, you will usually stop the sound by pressing the button that stops the alarm sound, but if you do not hear the sound, it tends to forget to replenish the medicine. is there. However, in the device according to the present invention, the emergency medicine replenishment alarm continuously outputs a signal at regular intervals. Therefore, even if the sound is stopped by pressing the alarm sound stop button, the alarm sounds again after 20 seconds. It is not possible to stop the sound easily until it is replenished and the reset button is pressed. Even if the alarm sounds when you are away, it is the same even if the receiver automatically chimes 3 times and automatically stops the alarm. Unless you refill the medicine or take special measures, can not stop. As a special measure, if the drug cannot be refilled immediately, a rule such as “unplug the receiver's power plug and move the receiver to the entrance” should be established. If an alarm sounds, you can never forget to replenish the drug if you only follow these rules.

Next, a fifth embodiment will be described with reference to FIG.
[0114]
The size, shape, installation status, etc. of the receiving tank vary depending on the size of the building and the purpose of utilization. Generally, it is a box-shaped container with a water depth of about 1.5m to 2.5m, but there are also those whose water depth exceeds 3m, and instead of installing a box-shaped container, a water-resistant tank is installed in the basement with a waterproof measure. There are also examples. Even in the latter case, a strict lid is provided to prevent the entry of mice and insects, and there are many manholes where people can enter and exit. For these large water tanks, installing a rust preventive device in the water supply pipe at the manhole entrance to replenish chemicals creates the risk of falling from a high place or falling from the manhole on the floor. .
[0015]
In addition to these dangers, it may not be desirable to install a device at the entrance and exit of the manhole for purposes such as water quality inspection and water tank cleaning. I made a prototype and tested it. The drug container 107 is of course a closed type rather than an open type with a hole in the side wall, but it is only for recirculating the water near the water surface of the water receiving tank to supply the solution, so it needs to be a very sturdy structure. Absent.
[0016]
Therefore, a transparent window can be easily provided in the container so that the remaining amount of the medicine can be visually recognized. However, since a medicine out alarm device is necessary anyway, the back of the cap 108 of the medicine container is provided. A drop lid with a magnet secured by a rope was inserted, the remaining amount of the medicine was detected by the sensor tube 226, and an alarm signal indicating that the medicine was out was transmitted. Although it was a short-term test operation, there was no difference in freshness compared to the case where the rust preventive device in the water supply pipe was installed in the water receiving tank.

【The invention's effect】
As described above, according to the present invention, it is possible to provide a system that eliminates rust in the water supply pipe due to aging, oxygen, chlorine, etc., and prevents the generation and growth of new rust at low cost, and is limited to night operation. Since the running cost can be suppressed by making it possible and self-management, it is possible to greatly extend the useful life of the building by introducing it as an early preventive maintenance measure. The reason why the anti-corrosion equipment using conventional chemicals was recognized in terms of the certainty of the effect and had a large demand, but the spread number did not increase for that reason was to eliminate concerns about the influence on the human body. It is thought that it was not cut. According to the present invention, even if water supply is used as usual, the amount of medicine taken into the human body can be reduced to about 1/3 of the conventional method (mainly only for breakfast), and water used for breakfast preparation. If you take a little time, for example, you can keep it in the afternoon of the previous day, you can reduce the intake to about 1/10 or less. The number of old buildings that have passed since the construction of the building has been rapidly increasing, and it has been able to boost the spread of rust prevention devices in water supply pipes that have been stagnant in the past, so that not only submersible pumps, electrical parts, electronic parts, A wide range of demands for various communication devices and rust preventives occur, and the effect of activating industrial production and distribution economy is achieved.
