Abstract

PURPOSE:To expand a moving range, namely, an extinguishing range while facilitating the movement of an extension hose by placing at least the extension hole on a caster in a fire hydrant which has a base hose connected to the extension hole through a hand valve fixed on the caster. CONSTITUTION:A water supply pipe 2 of a fire hydrant 1 is connected to a shaping hose 4 through a fire hydrant valve 3. The shaping hose 4 is made up of an inwardly winding type base hose 5 and an extension hole 6. Here, the base hose 5 is housed into a fixed type hose box 8 fixed on a wall surface 7. On the other hand, the extension hose 6 is housed in a mobile type hose box 11 set on a caster. Further, on the top of the mobile type hose box 11, a hand valve 13 is arranged to connect the base hose 5 to the extension hose 6. Thus. when a need arises, the caster 10 is moved to a place where a fire breaks out together with the extension hose 6 to get an extinguishing water jetted out of a nozzle 22. This constitution enables the expansion of an extinguishing range while achieving a quick fire extinguishing operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire hydrant with a truck.

[0002]

2. Description of the Related Art Conventionally, a fire hydrant, such as a No. 2 fire hydrant that can be easily operated, has conventionally been installed in a corridor. When a fire is discovered, the lever of the fire hydrant valve is tilted down, the hose is pulled to the fire area, and the fire extinguishing nozzle is installed. When opened, it released water and extinguished the fire.

[0003]

However, this indoor fire hydrant naturally has a limited hose length. Therefore, the area where the fire can be extinguished is limited, and the area usually has an effective radius of 15-
It is 25m. 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. It is also attempted to increase the water discharge distance by changing the elevation angle of the fire extinguishing nozzle with the hose extended to the maximum, but the water is not hit efficiently against the fire. Therefore, a water spray gun with a monitor is installed in such a large space, but it is difficult to operate and difficult to handle, and it is very expensive. Further, in the conventional fire hydrant, the hose is pulled to a fire place and transported while sliding on the floor surface, but the hose filled with fire extinguishing water is heavy. Therefore, when the hose slides on the floor surface, a large frictional resistance is generated, so that the hose cannot be easily transported. Therefore, the start time of fire-fighting activities may be delayed and initial fire-fighting may be difficult.

In view of the above circumstances, it is an object of the present invention to expand the fire extinguishing area and facilitate the transportation of hoses.

[0005]

The present invention is a fire hydrant in which a basic hose and an extension hose are connected via a hand valve fixed to a truck, and at least the extension hose is mounted on the truck. Therefore, the above-mentioned object is achieved.

[0006]

[Operation] When a fire occurs, the fire hydrant valve is opened to supply fire extinguishing water into the basic hose while moving the truck toward the fire. Then, the basic hose filled with water is supported by the carriage and conveyed to a predetermined position while extending. Next, open the hand valve and pull the extension hose to convey it to the vicinity of the fire area and direct the nozzle to the fire area to extinguish the fire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. A water supply pipe 2 of the fire hydrant 1 is connected to a shape retaining hose 4 via a fire hydrant valve 3. The hose 4 is composed of an inner winding type basic hose 5 and an inner winding type extension hose 6. The basic hose 5 is housed in a fixed hose box 8 fixed to a wall surface 7, and the extension hose 6 is housed in a hose box 11 with a carriage 10. At the top of the box 11, a basic hose 5 and an extension hose 6
A hand valve 13 for connecting to and is provided, and a weight plate 1 for stabilizing the hose box 11 is provided under the hand valve 13.
4 are provided.

Next, the operation of this embodiment will be described.
The fire-extinguishing worker A opens the door 12 of the fire hydrant 1, opens the fire hydrant valve 3, and moves the carriage 10 toward the fire place F. At this time, fire extinguishing water supplied from the water supply pipe 2 is filled and overlapped in the basic hose 5, but since the hose 5 is supported by the carriage 10, it can be easily transported to a predetermined place. Since this basic hose 5 is a shape-retaining hose, it will not be crushed by external force and will not twist. Also, when sending water, the water can be sent in a rolled state. Further, by inserting the universal joint 23 between the fire hydrant valve 3 and the basic hose 5 or in the middle of the basic hose 25, the kinking of the hose can be further prevented.
Furthermore, since the hand valve 10 is closed and the truck 10 is moved, the extension hose 6 on the truck 10 is not supplied with water. Therefore, since the extension hose is empty, the carriage can be moved in a light state.

As shown in FIG. 3, after the carriage 10 is moved to a predetermined position and the basic hose 5 is extended, the fire extinguishing worker A opens the hand valve 13, removes the nozzle 22 from the hose box 11, and removes the tip thereof. Extinguish the fire toward fire place F. At this time, if the distance between the carriage 10 and the fire place F is not within the fire extinguishing range of the nozzle 22, the nozzle 22
To pull the extension hose 6 until it is within that distance. If the extension hose 6 is formed to have a smaller diameter than the basic hose 5, the weight inside the carriage can be further reduced.

In the above embodiment, the carriage 22 is moved to a predetermined position and then the nozzle 22 is pulled out to extinguish the fire. However, when the fire hydrant 1 and the fire site F are close to each other, or where the floor surface is unstable or stairs, etc. In this case, without moving the carriage 10, the nozzle is pulled to extend only the extension hose 6,
May be located within the fire extinguishing range. In addition, a plurality of trolley-equipped hose boxes for storing the extension hoses 6 are provided,
The hose length of the shape-retaining hose 4 can be further extended by connecting the extension hose in each box.

The embodiment of the present invention is not limited to the above, and instead of housing the basic hose 5 and the extension hose 6 in separate hose boxes, for example, FIGS.
Place the hose box 31 on the carriage 30 as shown in
The central portion of the box 31 is partitioned by a partition plate 32 to form a basic hose box portion 31a and an extension hose box portion 31b, and the shape-retaining hose 4 is provided in each of the box portions 31a and 31b.
Can also be stored. In this case, the hand valve 33 that connects the basic hose 5 and the extension hose 6 is the partition plate 32.
Fixed on the top of. It goes without saying that this fire hydrant can be used not only indoors but also inside a tunnel or the like.

[0012]

Since the present invention is configured as described above, when the carriage is moved and the extension hose is extended, the total length of the hose becomes longer than that of the conventional example. Therefore, the fire extinguishing area is expanded as compared with the conventional example, so that even if a fire occurs in a large space such as an exhibition hall or an atrium, the fire extinguishing work can be quickly performed. Since the hand valve and the extension hose are mounted on the trolley, it is easy to transport the extension hose and operate the hand valve. Also, if you keep the hand valve closed, the inside of the extension hose will be light to maintain an empty condition.
The truck can be moved very easily, and fire extinguishing work can be performed quickly.
