Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a fire extinguishing device suitable for extinguishing fires in passageways such as tunnels, and in particular, to a fire extinguishing device suitable for extinguishing fires in passageways such as tunnels, and in particular, to reduce the amount of protrusion from the device box when in use. This project proposes an innovative forward-tilting reel type fire extinguishing system.

[Conventional technology]

It is important that the fire extinguishing system is constructed so that the hose reel, etc. does not protrude as much as possible from the equipment box even when in use. In addition, the inner walls of the tunnel are placed as close as possible to each other, so the fire extinguishing equipment installed inside the tunnel for use by passage users should be designed to protrude as little as possible from the inner wall to facilitate extinguishing operations. Vehicles, etc. must be able to evacuate without any hindrance even inside the fire, and since the fire is caused by the combustion of gasoline, it is especially important to be able to operate quickly, and drivers who are not familiar with fire extinguishing operations must be able to do so. Even if there is, for example, the structure must allow for easy operations such as pulling out the hose.

As a fire extinguishing device suitable for tunnels, etc., a hose reel is attached to a forward-tiling door whose lower part is pivoted by a horizontal undulating pin, and the door, which is in an upright storage position, can be folded forward and rotated. Jikosho developed a device that was designed so that the center of rotation of the hose reel is vertical and the direction of hose reel rotation coincides with the direction of rotation of the hose reel when the hose is in the operating position. Known as No. 52-41279.

Therefore, in this device, when the hose reel is in the operating position, the central axis of rotation rotates from a horizontal position to a vertical position, and the hose reel falls greatly toward the front.
The amount of protrusion toward the front from the equipment box is large, so this is not a problem when used in tunnels with wide monitoring passages, but if the width of the monitoring passage is narrow or there is no one, the position of use may change. sometimes,
There is a problem that the movement of automobiles etc. is obstructed.

[Problems to be Solved by the Invention] This invention has the lower door opened in a forward tilted position in which the upper part of the hose reel protrudes forward from the equipment box to the extent that the hose can be pulled out.
It is designed to minimize the amount of protrusion in the usage position.
