Description

  The present invention relates to a rainwater intake device that is attached to a downpipe that collects rainwater that falls mainly on the roof or rooftop of a building and flows down.

  In order to avoid the recent increase in environmental problems and local heavy rain damage, there has been an active movement to reuse rainwater. In some buildings, a dedicated tank is provided to reuse rainwater that has fallen on the roof and reused for flushing toilets and watering plants.

  However, it has not spread widely including ordinary households. The reason for this is that, unlike the water supply system, the switching device for draining rainwater and sand etc. that flows together will not function properly, so it automatically automatically filters only the amount of rainwater that falls down the downpipe. The amount of water intake is small compared to the amount of rain that falls with most of the water intake equipment, and there are many types that store the collected rainwater in a large tank, so it can be used as a dedicated tank including installation costs or water supply equipment for reuse. This may be due to the fact that the amount of water intake is small for the cost of installation. Also, in the city center, the area of the site is small and there is no place to put a dedicated tank, which is the reason why reuse of rainwater cannot be widely spread along with the amount of water intake and cost.

  The amount of rainwater filtered through a simple operation to remove rainwater can be taken through the downpipe, and when it is not necessary, it can be drained as it is, draining it as it is, equipment and installation costs are low, and a large tank for water storage is required If there is a water intake device that can use a commercially available plastic tank or bucket, more people will be able to store and reuse rainwater.

  Conventionally, there has been no water intake device that can be switched by a simple operation that can drain all rainwater without leaking from a vertical shaft through which rainwater flows in the building, and can be drained as it is when not needed. See Patent Documents 1 and 2

Patent Publication No. 10-306561

Patent Publication 2002-70086

  The rainwater intake joint described in the above-mentioned Patent Document 1 is such that the intake plate that forms part of the vertical rod attached to the vertical shaft is installed so that it can be opened and closed, and the rainwater flowing through the vertical rod is applied to the side by opening the intake plate. The rainwater that hits the intake plate bounces and part of it scatters around. In addition, this intake joint does not have a filtration function to remove sand and dirt flowing along with rainwater. In addition, it is possible that the intake plate cannot be opened and closed smoothly due to sand and garbage flowing along the fence.

  The rainwater intake joint described in Patent Document 2 passes through the filtration member to remove dust contained in the rainwater, so that even if the filtration member is clogged with dust, the rainwater will flow directly through drainage into the drainage. Yes. The filtration device can be easily removed and maintained, but when this fitting is installed, there is a filtering member in the vertical shaft that drains rainwater, so it is not possible to extract all rainwater while filtering it. I don't know how much water can be taken with respect to the amount of rainwater coming. Also, it is not a device that switches between taking rainwater or draining it.

  As described above, there was no device that could easily operate whether the rainwater flowing in the vertical shaft was drained or filtered without being leaked outside.

  As for the use of rainwater, it can be used for watering plants in gardens and flowerpots, vegetables in home gardens, and watering in hot summer, etc. If it is used in such a way, there is no problem in the above-mentioned use as long as a device that can quickly take in more rain is necessary and sand is removed. Furthermore, if purified rainwater is needed, it is possible to change the function and size of the filtration device and to take in the filtered rainwater by attaching it to the outlet from which the rainwater comes out. it can.

  Since the present invention allows rainwater to be stored and reused by more people, it is cheap and easy to install even in a private house, and the equipment does not break down due to garbage or dust flowing along with rainwater. It can also separate heavy debris such as sand, can take water in the required amount when it is needed without leaking it to the outside, and can install even more clean rainwater by installing removable filter media. We will provide rainwater intake equipment that is expected to increase.

In order to solve the above-mentioned problems, the first characteristic configuration of the rainwater intake apparatus according to the present invention is as described in claim 1, and a part of the vertical gutter is attached to the vertical gutter for flowing rain that falls on a building.

According to a fourth feature of the present invention, as described in claim 4, the filtration device 118 can be disassembled by removing the fixed band 122 and can be cleaned and replaced by removing the filtration net 119 and the water purification material 120 contained therein. It is in the point to.

The rainwater intake device of the present invention according to claim 1 is composed of four parts: a rainwater intake device main body, a rainwater receiving slide pipe, a vertical pipe mounting slide pipe, and a removable filtration apparatus. Because parts other than the water purification material can be made of steel, synthetic resin, vinyl chloride, etc., it can be made in large quantities at low cost, and the rainwater flowing through the vertical shaft is filtered without leaking to the outside by moving the rainwater receiving slide pipe. and the rainwater that Ya it is possible to flow the wastewater accumulated within the amount and tanks for rain withdrawn by an amount can be performed with a simple operation while viewing the rainwater received a cylinder with a rain water outlet of the slide pipe rainwater slide pipe By attaching it one step higher from the bottom part, heavy objects such as sand that flowed with the rainwater are settled on the bottom of the rainwater slide pipe and separated from the rainwater. After filtering the filter material, it is hard to cause clogging of the filter material, and a large amount of rainwater flows at a time unlike the case of installing the filter material in the downpipe by installing the filtration device after taking rainwater. It is possible to increase the filtration capacity and the filtration performance by increasing the surface area of the filter medium part where the rain water hits in the filtration device so as not to be lost. In addition, an overflow hole is prepared in the filtering device in case a large amount of garbage such as leaves flows at once and is clogged with a filtering net.

By removing the fixing pin attached to the rainwater intake device main body according to claim 2, the rainwater receiving slide pipe can be removed from the water supply device main body to remove sand, dirt, etc. deposited in the rainwater receiving slide pipe, and the holes removed. Since the inside of the water intake device can be cleaned by draining water, etc., cleaning and inspection are performed so that the rainwater intake device can operate without any abnormalities by removing small sand and debris that has flowed along with the rainwater and stuck in the piping. Is possible.

A rainwater intake device body according to claim 3 is attached to the inner wall surface of the rainwater intake device so that the rainwater flows well without leaking into the rainwater receiving slide pipe, and the sand and garbage flowing together with the rainwater are the inner wall of the rainwater intake device. It is possible to prevent the rainwater receiving slide pipe from moving smoothly and prevent the apparatus from malfunctioning .

The filtration device according to claim 4 can inspect and replace the filtration net and water purification material contained therein by removing the fixed band, and the water purification material can be made of shells, carbon fibers, ceramics, etc. It becomes possible to widen the use range of the rainwater taken out by using a thing with high filtration ability .
