Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher installed on a passage wall of a building, a bridge, a tunnel, a public facility, etc., and more particularly to a fire extinguisher suitable for a fire extinguishing activity when a fire occurs in a tunnel. .

[0002]

2. Description of the Related Art In a relatively small place such as a tunnel, a fire extinguisher is required to be installed in a small fire extinguisher because the installation place is limited. There is a demand for a fire extinguisher that can perform a quick fire extinguishing activity because of its high burning speed. In order to satisfy such demands, conventionally, an inspection path is provided on both sides of a road in a tunnel, and a fire extinguisher as shown in FIG. 5 is installed in a side wall facing the inspection path in an embedded state.

The structure of this fire extinguisher is such that a lid B is attached to the front of a device box A so as to be able to undulate and rotate forward, and the front end of a hollow shaft C is fixed to the lid B. C
The reel D is rotatably supported, and the base end of a hose E wound around the reel D is connected to a water supply pipe (not shown) via a rotary joint F connected to the hollow shaft C and a water tap valve G. In the event of a fire, the reel D mounted on the rear surface of the door B is rotated by tilting the door B forward and tilting the door B down.
Is exposed forward from the device box A, and the hose E wound around the reel D is pulled out to perform a fire extinguishing operation.

[0004]

However, since the fire extinguisher uses a rotary reel wound with a hose E, the hose E is smoothly supplied with water regardless of the rotation mechanism of the reel D and its rotation. There is a problem that it requires a complicated mechanism for making it possible and is expensive. Furthermore, the hose E is an elastic hose having a circular cross section and is wound around the reel D in multiple rows and multiple layers from the inner peripheral side to the outer peripheral side. E spreads due to its elastic restoring force, and it is difficult to keep the reel D in orderly wound due to its shape collapse. In addition, when the fire is extinguished, the hydrant valve G is opened and the hose E is opened.
When the fire extinguishing water is allowed to flow in, the hose E on the inner layer expands in the radially expanding direction due to the water pressure and bites between the hoses on the outer layer,
There is a problem that the feeding of the hose E may not be performed smoothly, which may hinder fire extinguishing activities that require quickness.

Further, if the hose E is wound on the reel D in multiple rows and multiple layers after the fire extinguishing operation is completed, the fire extinguishing water remaining in the hose E stays in the hose and water cannot be drained. This causes a problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object the simple structure, the compact installation in a narrow space such as the wall of a tunnel, and the installation in a hose storage box. The hose can be stored so that the storage of the hose is orderly and stable, and at the time of fire extinguishing activity, the hose can be smoothly pulled out of the storage box by a constant pull-out force, and quick fire extinguishing activity is possible,
