Description

[Detailed Description of the Invention] The present invention relates to a water spray repeater for firefighting that allows fire extinguishing work to be carried out in good condition at all times in any fire scene.

Generally, in firefighting operations using pump vehicles, two to four hoses are drawn out from one pump vehicle and each hose is extended to the fire site to spray water. Therefore, when the number of pump trucks in use increases, or when the pump trucks cannot get close to the fire site, there is a problem that a large number of hoses become congested, making it difficult to carry out fire extinguishing operations smoothly.

Further, the number of water inlets provided in one pump truck is 2 to 4 at most, and if the number of pump trucks is insufficient, the number of water discharge points cannot be increased arbitrarily. As a result, in the case of a surface fire that requires a large number of water spray points, it becomes difficult to quickly extinguish the fire, and there is a problem in that damage cannot be minimized.

This invention was devised to solve the above-mentioned problems in fire extinguishing operations using conventional pump trucks, and its purpose is to always extinguish the fire in the best possible condition, regardless of the fire or the situation at the fire site. To provide a water spray repeater for firefighting which enables work to be carried out.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

The firefighting water relay device 1 of the present invention includes a pair of wheels 2 facing each other as shown in FIGS. 1 and 2,
A closed tank 3 of an appropriate shape disposed at the center of these, a support 4 for fixing the rings 2 and 2 and the closed tank 3 to each other, and a plurality of valves attached to the surface of the closed tank 3. The main part consists of 5.

Specifically, the rings 2, 2 are formed into ring shapes having the same diameter by bending pipes, and are arranged so as to face each other.
The sealed tank 3 is formed in an appropriate shape, for example, a hexagonal column with a hollow interior, and its size is within the three-dimensional space S formed by the outer periphery of the two wheels 2 (as shown in FIG. 2). A hole 3a is formed in each hexagonal surface of the hexagonal surface.
Further, this sealed tank 3 is disposed at a central portion between the two wheels 2, 2, and these are fixed to each other by supports 4, 4, . . .

Ball valves 5 are attached to the holes 3a formed in the surface of the sealed tank 3, and each valve 5 is arranged so as to fit within the three-dimensional space S.

In the above embodiment, the wheels 2, 2 of the firefighting water relay device 1 are formed in the shape of a ring, but the rings 2, 2 are not limited to this, and may be formed into a disk. Further, the external shape of the sealed tank 3 is not limited to a hexagonal prism, but may be a cube, a rectangular parallelepiped, an octagonal prism, a cylinder, a sphere, or any other shape.
Further, the valve 5 is not limited to a ball valve, but may be a gate type valve or a globe type valve.

Next, the case of using the water spray repeater 1 for fire fighting according to the present invention will be explained.

The firefighting water relay device 1 is dropped from the pump vehicle 6 and rolled on the ground 7 in the state shown in FIG. When the firefighting water spray repeater 1 is rolled to the point where it is to be used, it is folded down to the state shown in FIG. After that, connect the water supply port 8 of the pump of the pump car 6 and any valve 5 of the firefighting water spray repeater 1 via the connecting hose 9, and connect the nozzle 10 to the connection part 5a on the outlet side of the other valve 5. Connect the provided water hose 11. Generally, the firefighting water relay device 1 is used in this manner.

To extinguish a fire, it is sufficient to open and close each valve 5 of the firefighting water relay 1. That is, by opening each valve 5 of the firefighting water spray relay 1, water is sent out from the water inlet 8 of the pump of the pump vehicle 6 through the connecting hose 9, each valve 5, and the closed tank 3 and water discharge hose. Water is discharged from the nozzle 10 through the nozzle 11.

FIGS. 3 to 5 show how the water spray repeater 1 for firefighting is used depending on the situation at a fire scene.

In other words, when there are many fires,
As shown in FIG. 3, the pump water supply port 8 of the pump vehicle 6 and one valve 5 of the firefighting water spray repeater 1 are connected by a connecting hose 9, and the other valves 5 are equipped with nozzles 10 for water spray. The hoses 11 may be connected to each other. In this way, even if the number of water supply ports 8 of the pump of the pump car 6 is limited, a large number of water discharge hoses 11 can be used, so that fires in several places can be extinguished at the same time.

In addition, in the event of a large fire, several pump cars 6 and 6 are used as shown in Figure 4, and the water supply port 8 of the pump is
and the valve 5 of the firefighting water relay device 1 may be connected by a connecting hose 9. In this way, the amount of water discharged from the nozzle 10 will increase, so even a large fire can be extinguished immediately. Furthermore, as shown in FIG. 5, a firefighting water relay 1 can be interposed between two pump cars 6 and 6, and this can be used as a relay base.

Since the water spray repeater for fire fighting according to the present invention has the above-described configuration, it has many excellent practical effects.

(1) The firefighting water relay system can be installed near the location of the fire, and the water hose can be pulled out from here, and a large amount of high-pressure water can be sent from a large fire engine to the relay system using a small number of connecting hoses. To extinguish a fire extremely smoothly at a fire extinguishing site without causing water hoses to become congested.

(2) Even if the number of water inlet ports on the pump of a pump vehicle is limited, a large number of water hoses can be used by using a firefighting water relay. As a result, even if many fires occur, the fires can be extinguished at the same time and damage can be minimized. It is also possible to supply water to the repeater from multiple pump trucks, making it easy to obtain the amount of water to be sprayed depending on the scale of the fire.

(3) If there is no water source near the fire site, the firefighting water relay can be installed between two pump vehicles and used as a relay point.

(4) Fire water relays can be rolled on the ground, so they can be transported quickly and easily. What's more, when the firefighting water relay is knocked down, its wheels serve as fixed legs, making it extremely convenient.
