DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cassette type fire hydrant system.

[0002]

2. Description of the Related Art Conventionally, a fire hydrant, for example, an easy-to-operate fire hydrant No. 2 is provided in a corridor or the like. Opening it released water and extinguished the fire.

[0003]

However, this indoor hydrant naturally has a limited hose length, which limits the area where fire can be extinguished, and the area usually has an effective radius of 15 to 2 mm.
5 m. Therefore, when a fire occurs in a large space such as an exhibition hall or an atrium, the hose may not reach and the fire may not be extinguished. Attempts have also been made to increase the water discharge distance by changing the elevation angle of the fire extinguishing nozzle with the hose fully extended, but water does not hit the fire efficiently. A water gun equipped with a monitor is installed in such a large space, but the operation is difficult and cumbersome, and it is very expensive. In view of the above circumstances, the present invention
An object of the present invention is to enable a fire extinguishing nozzle to be always located within a fire extinguishing range even in a fire in a room with a large floor.

[0004]

According to the present invention, there are provided a water supply box provided on a floor at a plurality of intervals, a cassette type fire hydrant having a hose with a fire extinguishing nozzle mounted on a truck, the water supply box and the fire hydrant. cassette provided with connecting means for connecting the
A fire hydrant system, wherein the water supply box is
It is characterized by being a concave accommodation part for inserting the fitting part of the car
A cassette type fire hydrant system to achieve the above object.

[0005]

[Function] In case of fire, push the cassette hydrant and move to the water supply box closest to the fire place. Then, after connecting the water supply box to the cassette type fire hydrant, the fire extinguishing nozzle is grasped and the hose is pulled out, and the fire extinguishing nozzle is positioned within the fire extinguishing range to extinguish the fire.

[0006]

An embodiment of the present invention will be described with reference to the accompanying drawings. The hose box 8 is placed on the trolley 10, and the hose box 8 is provided with the inner winding type shape retaining hose 5. The tip of the hose 5 is connected to the fire extinguishing nozzle 22,
The rear end is connected to the male coupling 6 via the hydrant valve 3. The coupling 6 is a quick coupling as shown in FIG. The leg portion 24 of the carriage 10 is a fitting portion 25 to be inserted into a water supply box 30 described later, and is formed vertically and the outside thereof constitutes a guide portion 24a.

[0007] A plurality of water supply boxes 30 are provided at a predetermined interval on a wide floor R such as an exhibition hall. The water supply box 30 is formed in a shape into which the fitting portion 25 of the cart 10 can be fitted, for example, a rectangular concave receiving portion, and its surface is flush with the surface of the floor R as shown in FIG. Is provided. At the center of the water supply box 30, a female coupling 31 connected to a water supply pipe 32 is provided to protrude. The female coupling 31 is a quick coupling configured as shown in FIG. 6, and the fitting portion 25 of the carriage 10 is fitted to the water supply box 30 and the male coupling 6 is automatically fitted when pushed down. It is pre-positioned so that it can be done.

Next, the operation of this embodiment will be described.
When a fire occurs, the fire extinguishing worker A opens the door 36 of the fire hydrant box 35, grasps the handle 37 of the cassette type fire hydrant 1, and moves the cart 10 toward the water supply box 30 closest to the fire place F. When the water supply box 30 is reached, the lid 26 is opened and the guide portion 2 of the fitting portion 25 of the cart 10 is opened.
4a is lowered while sliding along the side wall of the water supply box 30.

Then, the male coupling 6 shown in FIG.
Abuts on the female coupling 31 which is moved in the direction of arrow A6 and aligned. At this time, the handle 37 is moved to the arrow A6.
When pushed in the direction, the fitting portion 25 is fitted in the water supply box 30 as shown in FIGS. At this time, the male coupling 6 is fitted into the female coupling 31, the ball 38 enters the ball hole 39, and the valve body 16 is pressed by the projection 17 and moves in the direction of arrow A31 to separate from the valve seat 18 to open the valve. I do.
Then, the water in the water supply pipe 32 is coupled to the coupling 6, 31.
Flows into the shape-retaining hose 5 via the. In this state, the fire-extinguishing operator A opens the fire hydrant valve 3, grasps the fire extinguishing nozzle 22, pulls the hose, heads for the fire place F, positions the nozzle 22 within the fire extinguishing range, and extinguishes the fire.

After the fire extinguishing operation, when the fire hydrant valve 3 is closed and the handle 37 is pulled up in the direction opposite to the arrow A6, the male coupling 6 comes off from the female coupling 31. In this state, the carriage 10 is moved to the original position, and the lid 26 of the water supply box 30 is closed to make the floor R a smooth surface.

The embodiment of the present invention is not limited to the above. For example, not only an indoor fire hydrant system,
It can be used outdoors, for example, in a tunnel.
In addition, it is a matter of course that the water supply box may be provided not only on the floor of a building or the like but also on the surface of an outdoor sports ground or the like. Furthermore, in places where fire hydrants only need to be provided for a short period of time (in other words, places where indoor fire hydrants are not necessarily provided), that is, in exhibition halls where there are many exhibition booths, several fire hydrants are connected to the water supply box in advance. May be. In this case, in order to prevent mischief, a fire hydrant can be stored and a box provided with a door may be placed over the fire hydrant. If so, there is no need to go to the fire hydrant installed in the corridor etc., so it is suitable for initial firefighting. When the exhibition is over, it is very convenient to remove the indoor hydrant from the water supply box and put it in a warehouse or the like.

[0012]

According to the present invention, the fire hydrant can be connected to the water supply box located closest to the fire place when a fire occurs. Therefore, the fire extinguishing nozzle can be positioned within the fire extinguishing range, and the fire extinguishing effect can be significantly improved. Therefore, a fire that has occurred on a large floor can be quickly and efficiently extinguished by one cassette-type fire hydrant.
