Description

  The present invention relates to a fire hydrant storage box that draws out a hose with a nozzle and discharges fire-fighting water or fire-fighting foam.

  Conventionally, fire hydrant devices have been provided as emergency equipment for tunnels installed in tunnels such as expressways and automobile roads. The fire hydrant device has an openable fire hydrant door, and has a hose with a nozzle at the tip and a fire hydrant valve. Contains valves.

  The fire hydrant apparatus is generally embedded in the tunnel wall surface at intervals of, for example, 50 meters along the tunnel side wall. In the event of a vehicle accident involving a fire, in a tunnel with a supervisory passage, road users such as the driver of the accidental vehicle climb up to the supervisory passage by using steps installed on the side of the supervisory passage. A fire hydrant door of a fire hydrant device installed on a wall surface is opened forward, and a hose with a nozzle is taken out to perform fire extinguishing work.

  The observer passage is provided as a side wall passage that is raised with respect to the road surface, and it is possible to inspect various devices including fire hydrants installed safely in the tunnel without obstructing vehicle traffic in the tunnel. .

  Also, in a tunnel without a supervisor passage, a user such as a driver of an accident vehicle approaches a fire hydrant device installed on the wall of the tunnel, and similarly opens a fire hydrant door forward and a hose with a nozzle. The fire extinguishing work is done by taking out the water.

[Internal structure of fire hydrant storage box]
FIG. 7 is an explanatory view showing the internal structure of the fire hydrant storage box, FIG. 7 (A) shows the front, and FIG. 7 (B) shows a plane viewed from the YY cross section of FIG. 7 (A).

  As shown in FIG. 7, the inside lower side of the casing 31 in the fire hydrant storage box 30 is a hose storage portion 74, and a hose 76 having a shape retaining structure is overlapped in the horizontal direction and wound internally.

  Since the rectangle viewed from the plane of the housing 31 has a width of about 1.4 meters and a depth of about 0.35 meters, when the hose 76 is wound inside the hose storage portion 74, the inner winding of the hose 76 is performed. The shape is a rounded rectangle composed of two parallel lines and two semicircles. The length of one turn of the hose 76 wound inside the flat rectangular casing 31 is about 3.5 meters. Since the length of 30 meters or more is required, the hose 76 may be wound by 9 turns or more.

  Here, the hose 76 that is wound in a rounded rectangle inside the casing 31 is indicated by parallel line hose portions 76a and 76c and semicircular hose portions 76b and 76d.

  A hose guide structure 80 for deforming inward the parallel line portion 76a on the front side of the hose 76 that is wound in a rounded rectangle inside the casing 31 is provided on the center front side of the casing 31.

  In the hose guide structure 80, four guide pipes 80a, 80b, 80c, 80d using metal pipes are erected on the bottom plate 81, and the guide pipes 80a, 80d at both ends are erected along the inner surface of the housing 31, The central guide pipes 80b and 80c are erected apart from each other by a predetermined length, and the hose 76 is wound inward along the guide pipes 80a, 80b, 80c and 80d of the hose guide structure 80. The parallel line hose portion 76a is deformed inward to have a shape close to a gourd shape. Due to this deformation, a repulsive force is generated in the deformed parallel line hose portion 76a of the hose 76 to spread outward.

  By providing the hose guide structure 80 as described above, the hose 76 that is wound inwardly in the casing 31 is deformed inward by the hose guide structure 80 in the rounded oval parallel line hose portion 76a. Thus, even if the parallel line hose portions 76a and 76c of the hose 76 that are overlapped and wound internally become longer due to a repulsive force that tends to spread outward and a force that presses against the inner wall side of the casing 31, It is possible to reliably prevent the inside from collapsing.

  Here, the hose guide structure 80 deforms the parallel hose portion 76a on the front side of the hose 76 inward and the parallel hose portion 76c on the back side does not deform inward, but deforms inward of the parallel hose portion 76a. As a result, the force of spreading the hose 76 as a whole increases, and the parallel hose portion 76c on the back side that is not deformed inward can be reliably prevented from collapsing inward.

  Further, when the front door 32 and the second upper door 36 or the first upper door 34 are opened and the hose 76 is pulled out, the force for pushing out the hose due to the deformation of the radius hose portions 76b and 76d of the hose 76. In addition, the parallel line hose portion 76a of the hose 76 generates a force for pushing the hose 76 due to the inward deformation by the hose guide structure 80, and the pulling force of the hose 60 can be reduced.

  In the upper part of the hose guide structure 80, guide pipes 82a to 82d and guide pipes are provided so as to surround the inside of the front door opening 33, the first upper surface door opening 35 and the second upper surface door opening 37 shown in FIGS. 84a and 84b are disposed, and when the hose 76 is pulled out, it is brought into sliding contact with the guide pipes 82a to 82 or the guide pipes 84a and 84b, thereby preventing the hose 76 from being worn and reducing the hose pulling force.

  A foam nozzle 78 connected to the tip of the hose 76 is detachably locked to the back surface of the second upper door 36 by a nozzle holder 86. The nozzle holder 86 of the present embodiment locks the foam nozzle 78 by pivotally supporting the foam nozzle 78 on the back surface of the second upper door 36 and suspending it in a suspended state. When the first upper door 34 is opened rearward as shown by the first upper door 34a in FIG. 4 together with the second upper door 36, as shown in FIG. The nozzle holder 86 is locked to the back surface of the door in a state where the foam nozzle 78 is suspended.

  Therefore, when the second upper door 36 is opened forward or the first upper door 34 is opened rearward together with the second upper door 36, the foam nozzle 78 held in a suspended state on the back surface of the door appears at the upper part of the fire hydrant storage box 30. become.

  The position at which the foam nozzle 78 held on the back surface of the second upper door 36 is opened is approximately 0.9 to 1.3 meters from the road surface 15, which stands on the road surface 15. It corresponds to the range from the user's waist to the shoulder, and the foam nozzle 78 appears in front of the eyes, so that the foam nozzle 78 can be easily taken out.

  Moreover, the position where the foam nozzle 62 held on the back surface of the door appears by opening the first upper door 34 is approximately within a range of 0.2 to 0.4 meters from the road surface of the supervisor passage 14. The bubble nozzle 78 appears in front of the user who is bending the body in the member passage 14 and operating the rear opening handle 40, and the user can easily take out the nozzle 78 from the monitoring member passage 14 side.

  In addition, the nozzle holder 86 may be a split ring-shaped nozzle holder that is fixed to the rear surface of the door and opened to the detachable side for detachably locking the foam nozzle 78 in addition to the suspended type.

  In addition, an operation box is disposed inside the right side of the upper surface opening of the casing 31, and a fire hydrant valve opening / closing lever is provided on the operation box so that a manual pilot valve provided inside the operation box can be opened and closed. Although not shown in the figure. When the hydrant valve opening / closing lever is operated to open, the manual pilot valve is opened, and the hydrant valve separately disposed in the water discharge control mechanism storage unit 26 shown in FIG. 1 can be remotely opened.
