BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a water storage facility according to the present invention (hereinafter, referred to as "water storage facility of the present invention") will be described based on an embodiment shown in the drawings.

(First Embodiment) FIG. 1 is a schematic view showing a first embodiment of the water storage facility of the present invention. The water storage equipment 1 of the present invention according to the present embodiment includes a sealed water storage device 2 formed of a pipe and provided with an inflow port 3 and an outflow port 4, and for discharging air inside the water storage device 2 with the storage of water. An air bleeding device 5 and an air supply device 6 for applying air pressure for water supply to the inside of the water storage device 2 are provided.

The water storage device 2 is formed by stacking a plurality of divided water storage portions 7 that are long in the horizontal direction, and the vertically separated divided water storage portions 7 and 7 communicate with each other through a water pipe 8. 5 is joined to the divided water storage part 7, the inlet 3 is provided in the uppermost divided water storage part 7, and the outlet 4 is provided below the lowermost divided water storage part 7.
Is provided. Each of the divided water storage portions 7 includes a main body 7b formed of a pipe as a pipe member, and lids 7a and 7a formed of caps as pipe members covering both ends of the main body 7b. 8 and the ventilation pipe 9 are joined. The water pipe 8 connects the lower portions of the upper and lower divided water storage portions 7 and 7 so that the flow direction of water passing through the upper and lower divided water storage portions 7 and 7 is alternately changed. Vent pipe 9
Joins the upper parts of the upper and lower divided water storage parts 7, 7,
Each divided water storage portion 7 can be stored in a substantially full state. The pipes and caps, which are the pipe members, can be made of synthetic resin or metal manufactured and sold for water pipes, so that material cost can be reduced.

Since the water storage device 2 is of a closed type formed from a pipe, it can be configured from a small capacity to a large capacity by using existing piping members, and can be formed into a conventional panel type. The cost can be reduced in comparison. Each of the divided water storage portions 7 has a lid 7a, 7a on the main body 7b.
Can be fitted and assembled, so that there is no need to provide a working port for assembly. As a result, the water storage device 2 does not need to provide a work port with a cover which is indispensable in the conventional panel-type water storage tank, and is sanitary because there is no work port that causes ingress of dust. It should be noted that the water storage device 2 can be constituted by one device in which caps are joined to both ends of one pipe.

In the water storage device 2, the divided water storage portions 7 are connected to the supports 10, 10, and the whole of the casing 1 is provided.

It is preferable that the water storage device 2 has a heat insulating material made of urethane foam resin adhered to each of the divided water storage portions 7 to increase the overall rigidity and make the water storage device hardly broken even by an earthquake or the like. The water storage device 2 is installed under the floor outdoors or indoors, for example, by utilizing the legs of the supports 10, 10. The water storage device 2 includes a plurality of divided water storage portions 7 that are long in the lateral direction.
By stacking, the height can be increased and the water storage amount can be increased with a small installation area. In addition, the water storage device 2 may be configured (not shown) by stacking a plurality of divided water storage portions 7 into one row and further arranging a plurality of rows in front and rear.

The air is allowed to escape to the outside. It is preferable that the air release device 5 is provided above the water storage device 2 from the viewpoint of operability and the like. The on-off valve 13 is for preventing the water for water sent from the air supply device 6 to the inside of the water storage device 2 from escaping to the outside, and is closed after the water storage device 2 is full. The open / close valve 13 may be configured to be opened / closed by a dry battery type solenoid operating tool in addition to manual open / close operation. The reason for using the dry battery type solenoid operating tool is to consider a power failure due to a disaster or the like. In addition, the on-off valve 13 is operated by a timer-equipped operating tool that operates to open the water storage device 2 only for a set time that allows the water storage device 2 to be filled with water, and may be a normally closed type. In addition, the air bleeding device 5 can be configured only with the on-off valve 13 without using the automatic air bleed valve 12 such as a float type. In this case, the end of the air release can be confirmed by the transfer of the air discharged from the on-off valve 13 to the water.

The air supply device 6 includes a manually driven air pump 14 for applying air pressure for water supply to the water storage tank 21.
And a check valve 15 for preventing backflow toward the air pump 14. The air supply device 6 supplies compressed air generated by driving the air pump 14 manually or by manually stepping on the legs into the water storage device 2, thereby adding water stored in the water storage device 2. It is designed to be able to send water under pressure. The reason that the air pump 14 is driven manually is selected in consideration of a power failure due to a disaster or the like. The air pump 14 can be changed to a type driven by a dry battery. The air supply device 6 and the air release device 5 are generally installed indoors in consideration of operability. Since the structure of the air pump 14 is much simpler than that of the electric pump provided in the conventional water storage facility, the air pump 14 is inexpensive and can be easily maintained and inspected. The air supply device 6 may be configured so that a cylinder storing a gaseous substance such as compressed air or compressed carbon dioxide gas can be connected to the upstream side of the check valve 15 instead of the air pump 14. It is.

The water storage device 2 has a check valve 17 at the inlet 3.
The water pipe 16 is connected via the. Check valve 17
When the inside of the water storage device 2 is pressurized by the air supply device 6,
This is to prevent the water from flowing back to the water pipe 16. The water storage device 2 has a water pipe 18 extending from the outlet 4 via an on-off valve 19. The water pipe 18 is
In order to be able to cope with damage to the downstream side of the on-off valve 19 due to an earthquake or the like,
The first bypass pipe 22 with the on-off valve 21 and / or the second bypass pipe 24 with the on-off valve 23 may be joined. The first bypass pipe 22 opens the on-off valve 21 to take out water using the head pressure of the water stored in the water storage device 2. The second bypass pipe 24 is provided at a downstream side of the on-off valve 21 with a suction pump (not shown).
Is connected, the water stored in the water storage device 2 can be pumped up.

The water storage equipment 1 of the present invention can store water while evacuating the air inside the water storage device 2 with the air release device 5, and in the normal state after storing the water, the open / close valve 13 of the air release device 5 is closed and the inflow port 3 is closed. The water flowing from the water storage device 2 passes through the inside of the water storage device 2 and is sent to the outside from the outlet 4. When the water supply is cut off, the on-off valve 13 of the air release device 5 is kept closed, so that By applying air pressure for water supply with the air pump 14 of the air supply device 6, water can be supplied from the outlet 4 to the water supply pipe 18. Water storage device 2
In normal time after the water storage, the water flowing into the uppermost divided water storage part 7 from the inflow port 3 passes through the water pipe 8 and the lower divided water storage part 7 and flows out from the outlet 4 of the lowermost divided water storage part 7. Since the water is sent out, fresh water can be stored in each of the divided water storage portions 7 without forming a water stagnation portion.
