Description

The present invention relates to a fire hydrant device installed in a tunnel or the like.

For example, Patent Document 1 discloses a fire hydrant device including a hose accommodating portion for accommodating a fire extinguishing hose by winding it inward in a housing.
The hose accommodating portion of Patent Document 1 is described as follows: "Two rod-shaped bodies provided in the housing from the upper surface of the inner wall to the lower surface of the inner wall, and each of the two rod-shaped bodies, from the rod-shaped body to the rod-shaped body. It is formed by a hose bucket composed of strips bent in a substantially L shape provided so as to reach the back surface of the inner wall of the housing, and a central opening is provided between two rod-shaped bodies of the hose bucket, and the hose is provided. A corner opening is provided between the substantially L-shaped strip of the bucket and the upper surface of the inner wall and the lower surface of the inner wall of the housing "(see claim 1 of Patent Document 1).

The fire extinguishing hose accommodated in the hose accommodating portion is a shape-retaining hose having a hollow circular cross section and strong shape-retaining property, and is internally wound and accommodated in the hose accommodating portion.
As shown in FIG. 8, the inward winding is a winding method in which the fire extinguishing hose 43 is pressed against the frame from the inside of the frame called the hose accommodating portion 41, and the hose 43 is wound around the fire extinguishing hose 43. It is wound in the order of the numbers listed. That is, as shown in FIG. 8, the fire extinguishing hose 43 winds the outermost circumference in order from the rear toward the front (circled numbers 1 to 6), and when it comes to the frontmost, then one step from the outermost circumference. Go inside and wind from front to back (circled numbers 7-12). Further, when it reaches the rearmost side, it goes further inward and winds from the rear side toward the front (circled numbers 13 to 18), and so on.

When pulling out the fire extinguishing hose 43 housed in the hose accommodating portion 41, the fire extinguishing hose 43 (the 5th and 6th hoses shown in black in FIG. 8) located at the innermost part of the front row is shown, for example. When pulling out in the direction indicated by the white arrow in No. 8, the fire extinguishing hose 43 bends at a steep angle at the strip 45, and a large pulling force is required.
In order to prevent this, as shown in FIG. 8, a gap S is provided between the fire extinguishing hose 43 in the front row and the strip 45 at a predetermined interval, and the fire extinguishing hoses 43 located at Nos. 5 and 6 are provided. Even when the hose is pulled out, the fire extinguishing hose 43 does not bend at a steep angle, and a certain hose feeding radius can be secured.

Japanese Unexamined Patent Publication No. 2001-095943

In a tunnel, a fire hydrant device is generally installed in a box on the wall surface of a guard passage, for example.
However, in a tunnel whose wall surface is constructed of steel segments, such as a shield tunnel, it is not possible to remove the box, and other installation locations and installation methods are being studied. In that case, the most important thing is to make the housing of the fire hydrant device thinner.

Even if the housing is made thinner, the length of the fire extinguishing hose 43 accommodated in the hose accommodating portion 41 has a predetermined length, so that the diameter of one roll of the fire extinguishing hose 43 is increased. It is conceivable to reduce the number of steps in the front-rear direction by reducing the number of turns of the hose.
Then, the contact area between the fire extinguishing hose 43 in one roll and the surrounding wall or the outer fire extinguishing hose 43 increases. In this state, when the fire extinguishing hose 43 is filled with fire extinguishing water, the force for straightening the fire extinguishing hose 43 is large, and the frictional force is large because the contact area is large, so that the fire extinguishing hose 43 is used. Greater pulling force is required to pull out.

At this time, the most difficult to pull out is the fire extinguishing hose 43 (Nos. 5 and 6 in FIG. 8) located at the innermost side of the front row as described above, and the fire extinguishing hose 43 at this position can be pulled out smoothly. In order to do so, a gap S is required as described above. On the other hand, the need for this gap S has been one of the factors that hinder the thinning of the housing of the fire hydrant device.

The present invention has been made to solve such a problem, the diameter of one winding of the fire extinguishing hose to the hose accommodating portion can be increased, and the pulling out of the fire extinguishing hose is not hindered. An object of the present invention is to provide a fire extinguishing plug device capable of reducing the thickness of a housing.

The gap S between the front row of the inwardly wound fire extinguishing hose and the strip is required when the fire extinguishing hose is pulled out, and is not particularly required when the fire extinguishing hose is not pulled out.
Focusing on this point, the inventor thinks that the gap S can be secured only at the time of pulling out, and the housing of the fire hydrant device can be made thinner by eliminating this gap S when the fire extinguishing activity is not performed. rice field.
