Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency water storage device capable of supplying water even when water is cut off.

[0002]

2. Description of the Related Art An emergency water storage tank that can supply water even when water is cut off is an actual water tank which was previously filed by the applicant of the present invention.
No. 5 publication.

As shown in FIG. 4, the water tank described in the above publication has an inlet port 7 for connecting a water stopper 75 to a water container 1.
6 is provided, an outlet 59 is provided for allowing the water in the water retention container 1 to flow out from above the water retention container 1 due to the water pressure of the water filled in the water retention container 1, and the outlet plug 53 is provided at the bottom of the water retention container 1. Is provided.

[0004]

The water storage tank shown in FIG.
During normal times without water interruption, etc., open the water tap 75 and open the inflow port 7
6 is used to cause water to flow into the water retention container 1 and to cause the water stored in the water retention container 1 to flow out from the outlet 59 to replace the water in the water retention container 1 for use.

When the water is cut off, the spout 53 can be opened to use the water stored in the water container 1. The water storage tank is convenient because it can be used while the water in the water storage container 1 is being replaced during normal times to prevent water from spoiling and the like, and the water in the water storage container 1 can be used when water is cut off.

However, after the water in the water retention container 1 is used when the water is cut off, the water supply plug 75 must be opened to fill the water retention container 1 with water during the subsequent passage of water. Therefore, a manpower for operating the water tap 75 at the time of water flow is required. Therefore, if the water passage time is short and no person operates the water tap 75 during the short time, the water retaining container 1 cannot be filled with water.

Therefore, the applicant of the present application previously filed a Japanese Patent Application No. 6-272356 for a water storage tank having the above-mentioned drawbacks improved. Then, the improved invention is a water pouring circuit shown in FIG. 4 in which the water tap 75 is opened to allow water to flow into the water retention container 1 through the inflow port 76 so that the water flows out from the outflow port 59. In addition, as shown in FIG. 5, an inflow circuit for filling water after water is cut off is provided.

That is, a second inflow pipe 9 is provided in the water retention container 1 at a distance from the water pouring circuit, and the second inflow pipe 9 is
A valve mechanism 10 for closing the second inflow pipe 9 when the water retention container 1 is filled with water is provided, and the second inflow pipe 9 is connected to the second water tap 47 through the flow path 44.

The second water tap 47 is always open. Then, after the water supply is cut off and the water in the water retention container 1 is used, when the tap water is passed, the water retention container 1 is filled with water from the second inflow pipe 9, and the water retention container 1 is filled with water. When the water is filled, the valve mechanism 10 causes the second inflow pipe 9
Is to be closed.

However, in the improved water storage tank, when the joint 45 is separated due to vibration or the like, the second inflow pipe 9
Water will leak from. The present invention has been made in view of the above matters, and a device that can be used while replacing the water in a water storage device in normal times, when water is passed after water is cut off, it is possible to fill water without manpower required. ,
A technical issue is to prevent water leakage when abnormal force is applied.

Unless the force is large, the valve 28 and the outer end portion 17 do not separate.

In the invention in which the valve 28 and the outer end portion 17 are formed so as to be connected to each other by a conical cylindrical portion that closely contacts the conical cylindrical inner surface,
Even if a small force acts between the valve 28 and the outer end 17, the valve 2
8 and the outer end 17 are separated.

In the invention in which the valves 28 are connected in parallel by the tightening band 39, the valve 28 and the outer end portion 17 can be connected quickly.

Is closed.

When the first water tap 46 is opened in this state, the first
The water that has passed through the water tap 46 is supplied from the first inflow pipe 8 to the water storage container 1
Flows into. Then, the same amount of water as the inflowing water is extruded from the outflow port 59 to the outside above the water retention container 1 and flows out. Therefore, this water is used during normal times. And the first
When the water tap 46 is closed, the outflow of water from the outflow port 59 is also stopped.

If tap water runs out, tap 5
3 is opened or the pump device 54 is operated to extract the water in the water retention container 1 for use. Then, the water container 1
The water level inside falls. Then, the check valve 64 opens the air passage 65, sucks air into the water retention container 1, and releases the tap 5
Water can be poured out from the pump device 54 or the pump device 54 without any trouble.

Then, when the running of the tap water which has been cut off is restarted with the first water tap 46 closed and the second water tap 47 opened, the water passes through the second water tap 47 and 2 Automatically flows into the water retention container 1 from the inflow pipe 9.

When the water retaining container 1 is filled with water,
The valve mechanism 10 is closed, and the inflow of water into the water retention container 1 is automatically stopped. Therefore, at the time of water flow after the water is cut off, the water retention container 1 can be operated without manually operating the second water tap 47.
Can be filled with water.

Then, due to an earthquake or other accident, a force is applied between the first inflow pipe 8 and the second inflow pipe 9 and the valve 28,
When the valve 28 separates from the outer end 17, the valve 28 closes. Therefore, even if the first water tap 46 and the second water tap 47 are open, water does not flow out from the first water tap 46 and the second water tap 47.

Then, the valve 28 and the outer end portion 17 are connected to each other by the screw 30.
The valve 28 and the outer end portion 17 do not separate unless a large force is applied in the case of fixing and connecting with 24. The valve 28 and the outer end portion 17 are formed so as to be connected to each other by the conical tubular portion that is in close contact with the inner surface of the conical tubular member. Even if a small force acts between the valve 28 and the outer end portion 17, The valve 28 and the outer end 17 are disengaged.

When the valves 28 are connected in parallel with each other by the tightening band 38, the valve 28 and the outer end portion 17 can be connected quickly.
