(Effect of slide opening / closing mechanism that slides to the front side of the fixed door)
In addition, the front door is arranged at a position to close the front opening formed at the upper part of the fixed door arranged at the lower front part of the fire hydrant box, and is closed by locking the opening / closing operation unit arranged at the front edge side of the upper door. The slide opening / closing mechanism is slid down to open the front side of the fixed door when the front door is unlocked in conjunction with the opening operation of the upper door by the opening / closing operation unit. Therefore, even if the front door slides to the front side of the fixed door, the front door is opened and closed by a slide opening / closing mechanism located on the back side of the door, not the guides on both sides of the door. Therefore, the problem that dust adheres to the slide opening / closing mechanism does not occur.

  In addition, since the handle of the opening / closing operation part that uses the front door for opening operation is arranged on the upper front side of the fire hydrant storage box, when the user operates from the road side, it is on the road surface of the supervisor passage. Since the handle is at a close position, the user can easily and easily open the upper door.

  Here, the front door slide opening / closing mechanism that slides to the front side of the fixed door is, for example, a cylinder that is erected on the back side of the fixed door, and is fixed to the upper end of the back surface of the front door and is supported in a state extending downward from the back side The guide rod and the front door guide rod are arranged at the tip of the piston and slidably fitted into the cylinder.The mechanism is arranged in the casing on the back side of the door and exposed to the outside. Therefore, the front door can be opened reliably over a long period of time without dust adhering to the atmosphere in the tunnel.

(Effects of front door opening shock absorber)
In addition, when the front door slides and falls due to its own weight, a shock absorber is provided to loosen the movement of the front door to the open position. By providing the device, it is possible to open smoothly without causing an impact due to dropping.

(Effects of low friction contact on the door surface)
In addition, a low-friction contact member that moves in contact with low friction is provided on the opposite door surface of the front door that is opened and closed and the fixed door. Therefore, when the front door is unlocked, the front door is fixed by its own weight. Friction when sliding and falling while sliding on the door surface of the door is reduced, and the front door can be smoothly slid down and opened.

(Effects of front door opening and rear opening)
In addition, the upper door is arranged so that it can be opened and closed with the rear edge as an axis and can be opened and opened with the front edge as an axis. By opening the front door facing to the front and opening the upper door in the depth direction, the front upper part and upper surface of the fire hydrant storage box are greatly opened, and the hose with the nozzle can be easily and easily pulled out from the hose storage part. Can be extinguished.

  In addition, when the vehicle stops in front of the fire hydrant device and the user cannot operate from the road side, the user goes up to the surveillance staff passage and performs the opening operation after folding the upper door to the road side. Thus, the fire can be extinguished by easily and easily pulling out the hose with the nozzle from the hose housing portion without being obstructed by the stopped vehicle.

  In addition, since it functions as a fence when the upper door opens to the road side, when pulling out a hose with a nozzle from the upper opening, the danger of the user falling to the road side is avoided, and it is taken out from the inside It is also possible to prevent the nozzle from dropping on the road side.
