DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 is a fire extinguisher (fire extinguishing and water supply apparatus), and fire extinguishing apparatus (fire extinguishing and water supply apparatus) 1 is a schematic. Specifically, a tank 2 for storing water, a pump 3 installed below the water surface of the tank 2 and outside the tank 2, an engine 4 for driving the pump 3, a suction side of the pump 3 and the tank 2 And a discharge pipe 7 having one end connected to the discharge side of the pump 3 and the other end serving as a connection port 71 for connecting the fire extinguishing hose 8.

The inner wall of the tank 2 is made of, for example, polished stainless steel. Reference numeral 21 denotes a water supply port, and tap water (not shown) is supplied to the tank 2 via the water supply port 21. twenty two
Is a discharge pipe for the overflow.

The pump 3 is, for example, an automatic water absorption type pump, more specifically, NK-50B manufactured by Nagata Co., Ltd.

The swirl chamber (not shown) in the pump 3 is positioned below the water surface of the tank 2 so that the swirl chamber (not shown) is filled with water so that water can be quickly pumped. In this embodiment, in particular, the automatic water absorption type pump is used as the pump 3 when the water in the water supply hose S is automatically supplied when water is supplied into the tank 2 from the water tank truck 100 described later. This is to remove it.

The pump 3 is driven by the engine 4 via a belt 31.

The engine 4 is, for example, a NF19 diesel engine manufactured by Yanmar Co., Ltd.
A spare tank 41 for preliminarily storing fuel in a fuel tank (not shown) is arranged in water in the tank 2, and the spare tank 41 and the fuel tank (not shown) are connected by a fuel supply passage 42.

Although the auxiliary tank 41 and the fuel tank (not shown) are connected by the fuel supply passage 42,
Even if it is not connected with, at least the spare tank 41 is placed in the water in the tank 2 so that the fuel supply port to the spare tank 41 and the connection port to the fuel tank (not shown) can be connected later. It may be provided outside the tank 2.

Further, E is a drain for discharging the water in the tank 2 to the outside, and F is a fourth opening / closing valve.

Therefore, in the event of a disaster such as a fire, the water previously stored in the tank 2 can be used as it is without having to search for a fire hydrant, a river, a water tank or the like. As shown, the connection port 71 of the discharge pipe 7
If the fire extinguishing hose 8 is connected to and the engine 4 is driven to operate the pump 3, the fire extinguishing activity can be dealt with easily and quickly in the event of a disaster such as a fire.

In particular, if the fire hose 8 is connected to the connection port 71 in advance, in the event of a disaster such as a fire, the engine 4 is driven to operate the pump 3 and the first pipe provided in the middle of the discharge pipe 7. By opening the opening / closing valve A1 (opening / closing valve) No. 1, water can be discharged from the tip of the fire-extinguishing hose 8, and fire extinguishing activities (especially effective for initial fire extinguishing) can be dealt with more easily and more quickly. .

Further, the fire extinguisher 1 has a drawback that it cannot be moved and cannot be transported to a fire site as compared with a portable pump, but the output of the pump 3 is increased due to the fact that the pump cannot be moved.
It is possible to install an engine having good startability, lengthen the connected fire hose 8, and eliminate the need for a vacuum pump to compensate for the drawback.

Further, tap water is stored in the tank 2 through the water supply port 21, but in some cases, as shown in FIG. 3, a rainwater tank 101 is provided side by side on the side of the tank 2.

And a second opening / closing valve A2 provided in the middle of the water supply pipe 9, and normally closes the first opening / closing valve A1 and the second opening / closing valve A2 to extinguish the tank 2 in case of fire. In the case of a waterproof tank, the second opening / closing valve A2 is closed, and the first opening / closing valve A1 is manually opened. In the case of using the tank 2 as a tank for water supply, the first opening / closing valve is opened. The valve A1 is closed, and the second opening / closing valve A2 is manually opened.

The first switching means A may be a three-way valve for selectively connecting the discharge pipe 7 and the water supply pipe 9 and the discharge pipe 7 and the connection port 71 as shown in FIG. ,
A method of opening and closing the first opening / closing valve A1 (opening / closing valve) is excellent in order to easily and quickly respond to fire fighting activities in the event of a disaster such as a fire.

The second switching means B is, for example,
Third on-off valve B3 provided on the side close to the connection port 11
And a fourth opening / closing valve B4 provided in the middle of the suction side connecting pipe 5, and normally, the third opening / closing valve B4.
3 is closed and the fourth opening / closing valve B4 is opened to prepare for a fire and the tank 2 is used as a tank for water supply, the fourth opening / closing valve B4 is closed and the third opening / closing valve B3 is manually operated. To open.

The second switching means B connects the suction side connecting pipe 5 as shown in FIG. 5, or is a three-way valve for selectively connecting the suction side connecting pipe 5 and the water supply connecting pipe 10. Is also good.

Therefore, when supplying water, as shown in FIG. 6, the water supply hose S of the water supply vehicle 100 is connected to the connection port 11,
The first opening / closing valve A1 and the fourth opening / closing valve B4 are closed, the second opening / closing valve A2 and the third opening / closing valve B3 are opened, the engine 4 is driven, and the pump 3 is operated.
Water is supplied into the tank 2.

When a predetermined amount of water is accumulated in the tank 2, the handle C2 can be opened to distribute the water to the individual containers D as shown in FIG.

Although the above-described fire extinguishing apparatus 1 is of a fixed type, as shown in FIG. 6, a fire extinguishing apparatus (fire extinguishing and water supply apparatus) 1 may be provided on the movable base X so as to be movable.
