Description

  The present invention relates to a water storage device capable of always securing fresh water by directly connecting tap water to a water storage container.

  Conventionally, in order to secure drinking water in case of a disaster, it has been common to store water in a container or a water receiving tank. However, conventional tanks and containers are spoiled by the generation of algae and bacteria, so that there is a problem that the water stored in the tanks and containers must be periodically replaced and the tanks must be cleaned.

  As a technique for solving such a problem, for example, there is an emergency water storage tank disclosed in Patent Document 1. In this technology, circular and polygonal pipes or hoses with a diameter larger than the diameter of the current water pipes are placed in the middle of the installed water pipes, folded back to an arbitrary length, or arranged in a spiral shape. In one or more stages, tap water flows in one direction from the main pipe inlet at the top of the device to the faucet outlet at the bottom of the device, from upstream to downstream (direct current). ). A pump is provided at the faucet side outlet at the lower part of the apparatus, and water stored in the tank pipe is taken out by this pump.

According to the technique disclosed in Patent Document 1, each time tap water is used, the water flows through the tank pipe connected in series from the inlet on the main pipe side, flows toward the faucet side, Since the water always moves, fresh water can be always stored, and the water in the tank pipe does not come into contact with air containing germs, so that the water can be prevented from decaying.
Japanese Patent Laid-Open No. 9-310383

  However, since the technique disclosed in Patent Document 1 is based on the premise that water is forcibly circulated or taken by a pump, electric power for driving the apparatus is required, and the cost for storing water is low. There is a problem that occurs. Moreover, since power is required for water intake, there is a possibility that sufficient water intake may be difficult in an emergency such as a disaster.

  Then, this invention solves the above problems, and it aims at providing the water storage apparatus which can always ensure fresh water and can take in water, without requiring electric power etc. .

  In order to solve the above-described problems, the present invention provides a storage body having a hollow inside, a hose portion that is stored in a state of being wound around in the storage body, and stores water therein, and from the outside of the storage body to the inside. In addition to the inflow port connected to one end of the hose part accommodated inside the storage body and the hose part disposed through the interior from the outside of the storage body and stored inside the storage body An outlet connected to the end, a check valve that is provided at the inlet and suppresses the backflow of water by the water pressure in the hose part, and a water intake that is provided on the hose part side of the check valve and causes the water in the hose part to flow out With mouth.

  According to the present invention as described above, the normal water storage is performed by flowing water from the inlet to the outlet due to the pressure of the tap water, and in an emergency, the water stored in the apparatus can be taken out from the water inlet. Can be supplied even in the event of a disaster. Further, since a check valve is provided upstream of the water intake, fresh water is always stored in the apparatus without backflow of water in the hose portion.

  In the said invention, it is preferable that the mortar-shaped recessed part corresponding to the rolling diameter of a hose part is formed in the bottom face of a storage body. In this case, by winding the hose along the mortar-shaped recess, the hose portion can be efficiently stored in the storage body, and a dynamic water gradient for water intake can be easily ensured.

  Moreover, in the said invention, it is preferable that the said inflow port is arrange | positioned in the lower part of a storage body, and the said outflow port is arrange | positioned in the upper part of a storage body. In this case, the normal storage water flows from the inlet at the bottom of the device to the outlet at the top of the device due to the pressure of the tap water. Water can be taken from the water intake, and water can be reliably supplied even in the event of a disaster.

  In this case, it is preferable to further provide an emergency water stop valve that stops water when the water pressure on the downstream side of the outflow port fluctuates at the outflow port arranged at the upper part of the storage body. According to this emergency stop valve, water in the device can be prevented from being ejected from the outlet when the piping is damaged at the downstream side of the device (in-building piping) and the water pressure drops. On the other hand, when the water pressure on the downstream side rises during a disaster, it is possible to prevent sewage and the like from flowing back into the apparatus. And even if the downstream side is stopped by the emergency stop valve in this way, a check valve is provided at the inlet below the housing body, and further, the water flows downward (the inlet) due to the water head difference in the apparatus. Therefore, even in the event of a disaster, water can be taken out from the lower water intake without power while preventing outflow of stored water and inflow of sewage.

  The emergency stop valve is preferably composed of a pair of connectable valves and has a structure that allows water to flow when connected, and stops when an unchecked valve on the upstream side disconnects. According to this, in normal times, when a pair of valves are connected and become water-permeable, and a sudden change in water pressure occurs on the downstream side in the event of a disaster, the downstream valve will come off and sewage from the outside Is blocked, and the upstream check valve can prevent the water in the apparatus from being ejected.

  Furthermore, such an emergency stop valve may be provided on the inflow side (arranged above or below the storage body). In this case, the emergency stop valve is provided on the upstream side of the check valve, and the water is stopped by fluctuation of the upstream water pressure. According to this, it is possible to prevent the sewage generated on the upstream side from flowing into the apparatus by stopping the water when the upstream side of the water pipe is damaged and the water pressure fluctuates during a disaster.

  As described above, according to the present invention, it is possible to provide a water storage device that can always ensure fresh water and reliably take water even when a disaster occurs without requiring electric power or the like.

The hose portion 6 can be formed of, for example, a soft vinyl chloride material or a polyethylene resin.

  A check valve 7 is provided inside the inflow port 4 to prevent water from flowing back from the inflow port 4 due to water pressure in the hose portion 6. By this check valve 7, the tap water flowing into the hose part 6 through the inlet 4 is stored in the hose part 6 without flowing back from the inlet 4.

  Further, a branch pipe 41 is provided in the inflow port 4 outside the side surface of the storage body. The branch pipe 41 is located on the hose part 6 side (housing body side) of the check valve 7, and the water intake 8 through which water in the hose part 6 flows out is branched from the branch pipe 41. The intake port 8 is opened and closed by a valve 81, and the valve 81 is closed in a normal state, whereby the check valve 7 prevents back flow and the water is stored in the hose portion 6. On the other hand, by opening the valve 81 in an emergency, water in the hose part 6 can be taken out from the water outlet 8 due to a water head difference in the hose part 6.

  A valve 51 is provided at the outflow port 5 outside the side surface of the storage body so that the water flow at the outflow port 5 can be blocked. The valve 51 is opened during normal times, and the tap water supplied from the water pipe 12 through the hose portion 6 flows out to the pipe 11 side in the house 10. In the event of a disaster, the valve 51 can be closed to prevent the sewage generated on the house 10 side due to the disaster from flowing into the hose portion 6 from the outlet 5. In the present embodiment, a vent 53 that opens and closes in conjunction with the valve 51 is provided on the hose portion 6 side of the valve 51. That is, it is possible to ventilate the hose portion 6 with the valve 51 closed through the vent 53, promote water flow in the hose portion 6, and promote water intake from the lower water intake 8. .

  In the present embodiment, an emergency stop valve 52 that stops water when the water pressure on the downstream side of the outlet 5 fluctuates is provided at the outlet 5 disposed at the top of the housing 2. According to the emergency stop valve 52, the water in the apparatus can be prevented from being ejected from the outlet 5 when the piping 11 is damaged on the apparatus downstream (inside of the building) side and the water pressure drops in the event of a disaster. On the other hand, when the water pressure on the downstream side rises at the time of a disaster, it is possible to prevent sewage and the like from flowing back into the apparatus. And even if the downstream side is stopped by the emergency stop valve 52 in this way, in this embodiment, the check valve 7 is provided at the inflow port below the housing 2, and further, the water head in the apparatus Since water tends to flow downward (inlet 4 side) due to the difference, water can be taken out from the lower water intake 8 without power while preventing outflow of stored water and sewage even in the event of a disaster. it can.
