Description

   The present invention relates to an apparatus for sending a liquid by rotating a pump or the like with potential energy of its own weight such as water to be sent.

It is common to drive a pump with an electric motor to supply water. Of course, it doesn't work without electric energy. In case of an emergency, if you are unlucky and a power failure occurs, you will need to prepare a large capacity battery or engine generator, which is cumbersome and not cost effective. Therefore, the gas is confined to the tank at a high pressure, and the pump is rotated by the expansion force when it is opened, but the tank must be pressure resistant, and the cost is not reasonable and the amount of water delivered is limited. When injecting, there is a risk of explosion, which requires another high energy commensurate with it. There is a water storage tank at a high place, but the height must be determined according to the water supply pressure. In the case of a high place, when storing water in the tank, another pumping high energy is required.

Patent publication 2004-3521 The electric motor of another drive source is used to drive a pump.

In order to release water and liquid under pressure, another energy corresponding to the pressure is required.

The liquid weighs, for example, water if a specific gravity of 1, reservoir by way of example, water storage tank, weigh if volume 1 cubic meters of reservoir is 1 tons. If the force of 1 ton, 1000 kg weight is added to the water supply piston area of 20 square centimeters, it will receive 50 kg weight per unit area. Since the position pressure at a height of 10 m of water is 1 kg weight, this corresponds to a position pressure at a height of 500 m. If water is actually discharged, it will be lower due to the efficiency of the pump and the loss of the hose. If the difference between the upper and lower movement positions of the water storage tank is 1 m, the water storage capacity at the upper limit is 1 cubic m, and the water storage capacity at the lower limit is 0 (zero) cubic m, the height difference is 500 m with a position difference of only 1 m. The water will be used up. If the hose water is discharged with this position pressure energy, the discharge speed is about 100m / second at the start of discharge, but if the efficiency is 30%, the speed is about 30m / second, but at the end of the discharge, it becomes almost 0 (zero) m / second. End up. The discharge pressure is reduced according to the position difference. If the weight of the water storage tank is intentionally increased, a desired pressure can be obtained even immediately before the water storage capacity is 0 (zero). You may leave a part of the water storage or place a weight to intentionally make it heavier. In the event of an emergency, a human may ride or hang on the water tank . If it breaks down, it can be pumped out with a bucket.
Although anything good if those water-impermeable as a material of the water storage tank, easily moved folded in when not in use if light weight cloth. For outdoor and underwater, stainless steel, synthetic resin, etc. that are resistant to rust are desirable. The shape of the plane and elevation of the water storage tank may be any shape such as a circle, a cylinder, a triangle, and an inverted triangle. In addition, if the vertical length of the vertical surface of the water tank is shortened and flattened so that the horizontal length is increased accordingly, the position difference can be easily obtained. At least a part of the ceiling portion of the water storage tank is opened so that the water in the water storage tank flows out and flows in easily. I would like to prevent the occurrence of boufra, etc. by installing an insect screen or putting chemicals in the open part. In cold regions, it may be antifreeze.

Chain, such as transmission of reservoir and one end of the traction was lifted as suspended connected to a container such as a storage tank, the other end of the liquid, such as a pump to provide changing the potential energy to kinetic energy in the water, the fluid delivery device The rotation shaft may be rotated via a transmission so as to increase the number of rotations of the pump that is hung on the drive wheel of the rotation shaft. When the rotation speed of the pump is too early, the speed may be reduced. As a method of suspending a water tank , there is a structure in which a base is assembled, and a structure is built in the structure, a hole is dug in the ground, and a part or all of the water tank is inserted into the hole and suspended. Place the pump suction port at the bottom of the storage tank or storage tank, store the water in the tank, store it as it is, wait for it, or lower the storage tank, the rotation axis of the pump rotates by the weight of the storage tank, and the discharge port of the pump The water is drained vigorously. When the tank is lifted, a rotating tooth of an electric motor is connected to a pulling object such as a chain, and when water is stored in the tank, water may be supplied to the water storage port of the tank by an electric pump. In addition to suspending the water tank , the water tank may be supported and lifted by a column that moves up and down. If the rack teeth are installed on the support column and the pinion gear meshing with the rack teeth is installed on the pump rotating shaft or via the transmission, the pump can be driven. In addition, a water storage tank may be installed at the end of the seesaw, like a seesaw of a playground equipment, and a weight with a convenient weight may be installed at the other end so that it can be lifted lightly when the water storage tank becomes empty. In short, anything is acceptable as long as it falls by its own weight. With the seesaw type, the turning moment can be changed according to the angle between the horizon and the seesaw. Even if the liquid in the water reservoir decreases, the horizontal plane length of the seesaw increases, and the decrease in moment can be compensated to some extent. Depending on the location and installation conditions, the water tank may be placed on a cart and moved on an inclined surface. If the pump suction port is placed at a desired position away from the bottom of the water storage tank, the amount of residual water can be adjusted, and as a preliminary storage, the pump can be submerged in the residual water so that the pump does not absorb air Can also be used. A ball tap may be installed in the suction port in the opposite direction so that air is not surely sucked, and the suction port may be tightened when the buoyancy of the ball decreases and reaches a set water level. Adjust the descent speed of the water storage tank and attach a braking and locking device so that it can be stopped safely and reliably. In addition, assuming that the water tank falls due to cutting of a towed object that lifts the water tank, it is desirable to enter the fence with a fence such as a wire mesh to prevent accidents.
Other energy such as electric motors may be used to lift the water tank . I can do it easily. Other energy such as a supplementary electric motor may be used in combination with the self-weight energy for the fall. Water discharge pressure increases.

This device has a simple structure, and a large discharge pressure can be obtained with a slight positional difference, installation volume and area. A drive source that uses water storage and its own weight can be secured at the same time, and can be used anytime and anywhere. There is no noise. It takes a little energy to store water. If rainwater collected on the roof is used for water storage, it will fall naturally and energy and water costs will be free, and it will be nice and eco-friendly, and it will be useful for watering gardens, watering plants and washing cars. The water can be returned to its original position after it has been stored, but if the storage tank is used up and the water tank is empty, the water tank is lightweight and can be easily returned to its original position. It can be used in the event of a power failure because of its own weight and its own drive source, and can also be used as an emergency pump for fire fighting. A hole is made around the nozzle, and a negative pressure is created by the spraying effect, and liquids and gases such as drugs can be sucked and mixed from the hole. Bubbles can be easily obtained with air. Existing drums can also be used as water storage tanks .

Inexpensive, general-purpose parts, the minimum number of parts, and simple structure realize easy operation.

FIG. 1 is an external perspective view of the apparatus. The water tank , the water tank, and the water storage container 1 are hung on the mount 3 by the chain 2 and the common handle of the nozzle 5 of the hand hose 4 and the lever 6 are turned so that the water tank 1 is dropped by the water stop valve 7 and the brake wire 8. At the same time, the pump in the water storage tank 1 is driven to discharge water from the nozzle 5. The fall speed and water discharge amount of the water storage tank 1 can be adjusted by adjusting the handle and lever 6. The water stop valve 7 and the brake wire 8 may be operated separately. The lengths of the hose 4, the chain 2, and the brake wire 8 are sufficiently long even at the upper and lower limit positions of the water tank. The water tank 1 is lifted with the chain 2-1.

FIG. 2 is a diagram in which the pump 9 is installed outside the water tank 1. Connect the animal 1 such as the gear 10 that changes the linear motion to the rotational motion with the water tank 1 that stores water via the towed object such as the chain 2, and any other rope, friction wheel, etc. of the chain 2 can be used without slipping. A chain or a gear is preferably transmitted to the gear, and the gear 10 is engaged with the drive wheel of the rotary drive shaft of the pump 9 and the gear 11. When the number of rotations of the gear 11 is insufficient, a gear 12 that is coaxial with the gear 10 and is larger than the diameter of the gear 10 is installed and meshed with the gear 11 that is smaller than the diameter of the gear 12 on the rotation shaft of the pump. A belt may be hung between the gears 10, 11 or 12, 11 as in the continuously variable transmission CVT. Anything that can change gears is acceptable. When the water tank 1 descends, the rotary shaft of the pump turns and discharges water through the suction hose 13, the pump 9, and the water discharge hose 4. The rotational speed of the gear 12 is braked and controlled by a frictional resistance such as a brake so that it can be stopped halfway or the rotational speed can be adjusted. In order to raise the water tank with a small force, a gear 14 smaller than the diameter of the gear 12 may be engaged and the handle 15 may be rotated. If the disk plate 14-1 is installed on the gear 14 and is sandwiched by the brake 16 or the like, the rotational speed of the gear 12 can be braked and controlled with a smaller frictional resistance. The disk plate 14-1 may be installed coaxially with the gear 10 in addition to the coaxial with the gear 14. Thus, any axis that rotates when the water tank is lowered may be used. A chain 2-1 is hung on the gear 14 that rotates when the water tank rises. The disk plate 14-1 may be installed on the shaft so that the force is transmitted only in one direction and idles in the opposite direction. The water tank can be raised while the brake 16 is applied. The gear 11 may also be installed on the shaft so that the force is transmitted only in one-way rotation and idles in the reverse direction. Pump does not drive when lifting aquarium. The connection point of the towed object with the water tank can be any position that can support the water tank at the bottom, top, or ceiling. In the case of the bottom, the upper part 17 is held so that the water tank does not tilt. Also with a check valve 18 ahead of the hose 13 so as not to air enters functions impossible to suction hose 13, it established a priming tank 19 to a pump 9 to fill always water. The length of the hose 13 is set to a length sufficient to suck the bottom water even when the water tank 1 is fully lowered. Since pumps are outside the water, it is difficult to rust and has a long life, but it is troublesome to keep the suction hose 13 full.
When the pump input is excessive or desired to be a desired size, the weight sharing of the water storage tank 1 may be reduced by using the constant driving wheel 20 and the dynamic driving wheel 21. One end of the towed object such as the chain 2 is connected to a fixed object such as a gantry, and the other end is wound around the constant driving wheel 20 and the dynamic driving wheel 21 once or a plurality of times, and hung on the gear 10. The force to lift the aquarium is light and small. The rotational speed of the constant drive wheel 20 and the dynamic drive wheel 21 can also be changed.

FIG. 3 is a diagram in which pumps and transmissions are installed on the water storage tank . The weight of pumps can be used as potential energy.
Pumps and transmissions are installed on the water tank . If the drive shaft of the pump is connected to the dynamic drive wheel 21 using the constant drive wheel 20 and the dynamic drive wheel 21, and the number of turns between them or the diameter of the constant drive wheel 20 or the dynamic drive wheel 21 is changed, the rotation speed of the pump is adjusted. I can do it. The drive shaft of the pump may be connected to the constant drive wheel 20. When the handle 15 and the brake 16 are not reachable, the water tank 1 is moved up and down by turning the handle 22 pulled or engaged with the chain 2-1. In addition, a weight is attached so that the towed object such as the chain 2 is lowered by gravity, or it is installed obliquely. Moreover, you may wind around the drum 23 so that it may be easy to arrange. Install the drain valve 24 at the bottom for cleaning and inspection.
The pump 9 and the transmissions are installed in the bottom of the water storage tank and in the water. Priming tank 19 so to always pump 9 water is filled may not be attached. The tank upper part is inserted and held in a pipe 17 having a through hole so that the water storage tank does not tilt. Discharge pipe 4 of the pump may be passed through the bath bottom. In this case, a water stop valve 7 is attached to the nozzle 5. The water stop valve 7 may be attached even if the discharge pipe 4 does not penetrate the tank bottom. The rotational speed of the disk 14-1 installed on the gear 14 is braked and controlled by the brake 16. Water storage tank 1 of the lowering speed of the adjustment also safety may be reliably brought brake 16 of the braking apparatus capable of stopping the rotation of the shaft movement and water shut-off valve 7 is interlocked with the brake wire 8, falling water tank Water discharge is 1 action, and it is easy to use at the same time ...

If the rack teeth 26 are installed on the support column 25 of the water storage tank 1, the pinion gear 27 meshing with the rack teeth 26 is installed on the pump rotation shaft or via the transmission, and the support tank 25 is held by the presser wheel 28, the water tank The column 25 moves downward with the weight of 1 to drive the pump 9...
The support column 25 may be installed on the upper part of the water tank 1 and may be hung instead of a towed object such as a chain as indicated by a circled number 1 in FIG.

FIG. 5 shows, as an example, a propeller, a screw and a piston, and a centrifugal pump that are used in the present apparatus. In addition, any non-volumetric pump, volumetric pump, etc. that can supply water by changing the positional energy to kinetic energy may be used. .
Turn the propeller and screw 29 to push out the water. The outlet may be constricted to increase the flow velocity.
It pushes out water with a piston. When the piston 30-1 moves in the direction of pushing out the water, the piston 31-1 of the suction port pressed by the compression spring is closed, and the piston 32-1 pressed by the compression spring is pushed over the force of the compression spring. Pour water. The other piston 32-2 is pushed and does not open. When the piston 30-2 moves in the suction direction, the piston 32-2 closes, and the suction spring piston 31-2 opens and fills the cylinder 33 by overcoming the force of the compression spring. The piston is connected by the link 34 and the rod 35 shifted by about 180 degrees, and the gears 11 are rotated to move the pistons 30-1 and 30-2 simultaneously. If the discharge port is closed, the pistons 30-1 and 30-2 are stopped, so that the falling of the water storage tank can be controlled at hand. In this case, it is desirable to prevent the pump from being driven when the water tank is lifted as shown in FIG.

The inner cable 8-1 of the brake wire 8 is connected to one end of a V-shaped arm grip and the outer skin 8-2 is connected to one end of another V-shaped arm grip so that it can be operated remotely. If the compression spring 39 is installed between the grips of the two arms, the wire is pulled only when the grip is held, and if it is released, it returns to the original state by the spring force, so only one brake wire is required. When the grip 40 at one end of the arm pivotally supported at the intermediate point is pushed so that the wire can be pulled at the hand of the hose, the other end of the grip arm is opened, and the wire is connected to the other end. Further, as shown by the circled numeral 2 in FIG. 3, a male screw is cut into the extension shaft of the water stop valve 7 and a female screw is cut into the grip 40, and the handle and lever 41 are turned to open and close the water stop valve 7 and the inner cable 8-1.

When a water storage tank is placed at the tip of the seesaw 51 and lowered by its weight, the pump is driven by the generated torque to discharge the liquid. As the water storage tank is lowered, the weight of the water storage tank is reduced. However, since the horizontal projection length L1 of the seesaw 51 is increased, the decrease in torque can be compensated to some extent. If the decrease in the weight of the water storage tank is smaller than the increase in the horizontal projection length of the seesaw 51, it can be increased. The rotation angle θ1 of the seesaw 51 is preferably within 90 degrees, but may be within 180 degrees of the rotation angle θ2 of 90 degrees below. The moment can be increased or decreased by the relationship between the decrease in the weight of the water tank and the increase or decrease in the horizontal projection length of the seesaw 51. At least the rotation angle θ1 and θ2 of the seesaw 51 is a gear 12, and the disk plate 14-1 is fixed to the same shaft, and the shaft is pivotally supported so that it can be rotated on a support column. Is to turn. The rotation of the disk plate 14-1 is braked and controlled by a brake 16 or the like held on a column or the like. The torque may be adjusted by the weight 52 so that the empty water tank can be easily lifted. The weight 52 may be omitted. In addition to holding the weight 52 and the seesaw 51 to move the water tank up and down, the handle 15 meshed with the gear 12 may be rotated.
