Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency water tank which serves as both emergency water used when water is cut off or fire and water for daily life.

[0002]

2. Description of the Related Art The damage caused by an earthquake is not only caused by physical collapse of a house due to shaking but also caused by a fire caused by a collapsed house. The most important thing in such a fire is the so-called initial fire extinguishing before the arrival of the fire engine, and by doing this early fire extinguishing properly, most of the fires stop the damage to a minimum. be able to.

In order to properly carry out such an initial fire extinguishing, it is most effective to have a water tank for extinguishing fire in each house, and therefore, in the law concerning buildings in recent years such as the Fire Defense Law, Fire extinguishing equipment must be installed on objects.

The most common fire extinguishing equipment is to provide a water tank in the underground of the room, etc., and further, to provide a pressurized water supply device (pump) for pumping water in the water tank, a pipe to a predetermined location, and It is provided with a fire hydrant or sprinkler having a fire hose connection port provided at the tip of the pipe.

In the event of a fire, a fire alarm device installed on the ceiling of the living room detects heat or smoke, the sprinkler automatically operates, and high-pressure water for fire extinguishing can be jetted from the fire hydrant.

However, in the case of an indoor fire extinguishing facility installed underground, it is effective in the case of a normal fire,
In the case of a large-scale earthquake, the fire extinguishing equipment itself is often buried along with the collapse of the house, making it unusable.

[0007] On the other hand, as a solution to such a problem to some extent, there is known a so-called outdoor fire hydrant facility in which a water storage tank is provided outdoors underground and a pipe for extinguishing a fire is provided indoors from the water storage tank.

With this outdoor fire hydrant equipment, the water tank is rarely buried even when the house collapses, and it can be said that it is relatively strong against earthquakes.

[0009]

However, in the conventional outdoor fire hydrant equipment, since the water tank to be buried underground is made of concrete, concrete which is particularly vulnerable to pulling force due to shaking during an earthquake is adopted. There is a problem that the wall is cracked and the water in the stored water tank leaks to the outside. Furthermore, since the conventional equipment is operated by a power source device such as a general power source or an in-house power generator, when the power outage or the in-house power generator is broken, the equipment is completely up.

On the other hand, in a general house that does not have a water tank, not only is there no provision for water for extinguishing water in the event of a fire, but also when water is cut off due to an accident in water supply equipment or piping due to an earthquake or typhoon. , There is a problem of being in need of immediate living.

The present invention solves the above-mentioned problems in the conventional fire extinguishing equipment and the problem when water is cut off in a general house, is not easily affected by the collapse of a house during an earthquake, and is a power source such as a general power source and a private power source. It is an object of the present invention to provide an emergency water tank that can be used even in the event of an emergency.

[0012]

In order to achieve the above object, an emergency water tank of the present invention is connected to a water tank main body made of a synthetic resin buried in the ground outdoors and the other end is connected to a water supply source. The water supply pipe and the water pipe whose other end is connected to the home pipe and the water pipe for sending the water in the water tank body to the outside are respectively connected, and the other end of the water pipe is connected to the home pipe. Further, an electric pump and a manual pump for pumping the water in the water storage tank to the in-home pipe are provided in the middle of the water supply pipe.

Here, the main body of the water tank is FRP.
It is possible to use synthetic resin having a strong tensile force such as (fiber reinforced plastics), but a corrugated flexible tube having excellent strength is particularly preferable.

Further, it is possible to provide a water discharge pipe having a connection port for a fire extinguishing hose at a tip end, which is branched from the water supply pipe, or a hose connection port for connecting a fire hose to the water tank body.

Furthermore, by housing the water tank body in an outer container buried in the ground, the strength against rolling can be improved particularly during an earthquake.

[0016]

[Advantage] By adopting a synthetic resin tank as the main body of the water tank buried in the open ground, it is possible to greatly reduce the occurrence of cracks that cause water leakage as compared with the conventional concrete tank.

Further, since the water pipe whose other end is connected to the in-home pipe is connected to the main body of the water tank, the water for domestic use is always supplied by this water pipe, and the electric pump or the manual pump is supplied at the time of water interruption or fire. With this, the water in the water tank body can be sent. At this time, since the electric pump and the manual pump are provided as the pressure feeding pump, the pump can be operated regardless of energization or power failure.
