An embodiment of the present invention will be described with reference to FIGS.
A simple fire hydrant device 5 is provided on the side wall 3 of the road tunnel 1, and a fire detector 7 is disposed at the center of the ceiling (see FIG. 5).

A plurality of fire detectors 7 are arranged at predetermined intervals right above the center of the roadway 10 (just above the center line 12), and each fire detector 7 monitors its own fire monitoring area ( (See FIG. 6).
In the present embodiment, the fire is monitored by the fire detector 7, but a flame detector may be provided on the tunnel wall surface and the fire monitoring area may be monitored by the flame detector.

  A plurality of the fire hydrant devices 5 are arranged at predetermined intervals along the longitudinal direction of the roadway 10 (see FIG. 6). A main body 14, a hose housing portion 16, a hose 17, a fire extinguisher 18, and the like are housed in the cabinet body 13 of the simple fire hydrant device 5. A forward tilt door 20 and a fire extinguisher door 22 are provided on the front surface of the cabinet body 13. A nozzle 24 connected to the tip of the hose 17 and a lever 26 for opening and closing the main valve 14 are provided on the back surface of the forward tilting door 20 (see FIGS. 1 and 2).

  The forwardly inclined door 20 is kept closed by an electromagnetic opening / closing unit 30 which is an electromagnetic opening / closing means. The electromagnetic switching unit 30 includes an electromagnet 31, a hook 33, and a hook metal fitting 35 (see FIGS. 3 and 4).

  The electromagnet 31 is formed in a U-shape, and the upper base end thereof is fixed to the cabinet body 13. The electromagnet 31 is controlled by a control unit (not shown) provided in the cabinet body 13. The control unit causes the electromagnet 31 to become magnetized when a receiving unit (not shown) receives a fire signal from the monitoring center (control panel) 37 or a push button type notification device (not shown). Is generated.

  The hook 33 is disposed on the lower inner wall of the U-shaped groove 31 a of the electromagnet 31 so as to be able to rise and fall, and is normally erected and engaged with the hook metal fitting 35. When the magnetic force is generated in the electromagnet 31, the hook 33 falls down, so that the engagement with the hook metal fitting 35 is released.

  The hook fitting 35 is a bowl-shaped or U-shaped metal body, is inserted into the U-shaped groove 31 a of the electromagnet 31, and engages with the hook 33. Since the metal fitting 35 slides toward the front tilt door 20 when a magnetic force is generated in the electromagnet 31, the front tilt door 20 is opened.

Each fire detector 7 is connected to a monitoring center (control panel) 37, and a fire signal of each fire detector 7 is transmitted to the monitoring center 37.
The fire monitoring area of each fire detector 7 and the fire extinguishing area of each simple fire hydrant device 5 are designed to correspond to each other. For example, the first fire detector 7a detects a fire. In this case, the first fire hydrant device 5a having the corresponding fire extinguishing region is selected as the fire hydrant device arranged at the most appropriate position.

Next, the operation of the present embodiment will be described. First, the fire monitoring time (normal time) will be described.
Each fire detector 7 constantly monitors the fire, and the forward tilting door 20 of each fire hydrant device 5 is kept closed by the electromagnetic opening / closing unit 30.
At this time, since the hook metal fitting 35 is locked to the hook 33 in the standing state, the hook metal fitting 35 cannot slide (see FIG. 3).

Next, a description will be given of when a fire occurs (when an abnormality occurs).
Usually, fires that occur in the road tunnel 1 are often caused by car accidents or breakdowns. Thus, when a fire occurs due to a car accident or the like, each fire detector 7 that detects the fire sends a fire signal to the monitoring center 37. Then, the monitoring center 37 selects the nearest fire sensor (first fire sensor) 7a closest to the fire source 40 based on the received fire signal from each fire sensor 7 and A fire signal (command signal) is transmitted to the receiving unit of the nearest fire hydrant device (first fire hydrant device) 5a corresponding to the fire detector 7a.

  The reception unit of the latest fire hydrant device 5 a drives the control unit to generate a magnetic force in the electromagnet 31. As a result, the hook 33 falls and the engagement with the hook metal fitting 35 is released, and the metal fitting 35 slides toward the front tilt door 20 and rotates the front tilt door 20 in the direction of arrow A20. The forward tilting door 20 is opened, and the tip portion thereof protrudes on the inspection path 42 (see FIG. 5).

At this time, when the driver of the accident vehicle that caused the fire source 40 escapes from the vehicle safely, the forward tilting door 20 of the latest fire hydrant device 5a is open. Can start activities.
Even if the driver of the accident vehicle cannot escape, the following automobile 45 is traveling in the direction of the arrow A1 in the road tunnel 1, so that the driver of the automobile 45 is in front of the open latest fire hydrant device 5a. Close to the fire source 40 while noticing the tilted door 20. And the said driver stops the motor vehicle 45 in the vicinity of the said immediately previous fire hydrant apparatus 5a, and starts fire fighting activity using the said latest fire hydrant apparatus 5a, without getting lost.

  That is, the driver pulls the lever 26 disposed on the back surface of the forward tilt door 20 to open the main valve 14, removes the nozzle 24 from the nozzle holder, and pulls the hose 17 while pulling the nozzle 24 to the fire source. Water discharge to 40 is started.

In the embodiment, only the forward tilting door 20 of the latest fire hydrant device 5a corresponding to the latest fire detector 7a is opened. However, the forward tilt of the fire hydrant device corresponding to the fire detector in the order closer to the fire source 40 is opened. The doors may be opened sequentially.
For example, in addition to the latest fire hydrant device 5a, the forward tilting door 20 of the second fire hydrant device 7 corresponding to the second fire detector 7 closest to the fire source 40 may be opened.
In this way, the person who first uses the fire hydrant device closest to the fire source and later comes to the fire extinguisher easily becomes aware of the fire hydrant device next to the fire source, so that the fire can be efficiently extinguished.

Furthermore, as described above, instead of deciding the order of the fire hydrant devices to be opened at the monitoring center and sending a fire signal to the receiver, the front tilt doors of each fire hydrant device corresponding to each fire detector that has detected a fire are provided. You may make it open all.
In the embodiment, the electromagnet 31 and the hook 33 may be provided on the forward tilting door 20, and the hook metal fitting 35 may be provided on the cabinet body 13.
Further, when the forwardly inclined door 20 is divided into upper and lower parts, either one may be provided on the upper door and the other may be provided on the lower door.

  In addition to the fire signal from the fire detector, the door can be opened by a fire signal from a push button type notification device. Moreover, you may make it open the door by the fire signal of both the said fire detector and the said notification apparatus.

A second embodiment of the present invention will be described with reference to FIG.
The difference between this embodiment and the first embodiment is that the simplified fire hydrant apparatus 5 is provided with an initial motion assisting means.
This initial motion assisting means is a solenoid 47 and is disposed in the contact portion 49. The abutting portion 49 is located at a portion of the cabinet body 13 where the upper end side of the forward tilting door 20 abuts.

  The solenoid 47 uses a movable iron core (plunger) 50, which is a ferromagnetic material, and a fixed iron core as an axial core, winds an insulating wire around a bobbin formed of an insulating material, and generates magnetism by passing an electric current. The frame 51 is made up of a coil and an electromagnetic circuit that efficiently passes the magnetism generated by the coil, and includes a non-magnetic pipe that serves as a guide for smoothly operating the movable iron core 50. The solenoid 47 is provided with a receiving unit that receives a fire signal and a control unit that controls an electromagnet based on the receiving unit.

In the second embodiment, the monitoring center simultaneously sends a fire signal to the simplified fire hydrant device and the solenoid receiver when an abnormality occurs.
When the receiving unit of the solenoid receives the fire signal, the receiving unit drives the control unit to cause a current to flow through the coil to generate a magnetic force. Therefore, the movable iron core 50 slides, and the tip 50a of the movable iron core 50 presses the upper end portion of the front tilt door 20 forward, so that the front tilt door 20 is fixed by exhaust gas, dust, or the like. Even if it is difficult to open, the door can be opened reliably. In the second embodiment, the initial auxiliary means is provided on the cabinet body 13, but it goes without saying that it may be provided on the front tilt door 20 side.

A third embodiment of the present invention will be described with reference to FIG.
The difference between this embodiment and the second embodiment is that a hydraulic cylinder mechanism 57 is used as the initial motion assisting means.

  The hydraulic cylinder mechanism 57 includes a cylinder 59 that houses a piston 58 and a spring 61, a rod 60 that connects the piston 58 and a connecting portion 20d of the forward tilt door 20, and the cylinder 59 and a water supply main pipe (not shown). A water pipe 62 to be connected, an electromagnetic valve 64 disposed in the water pipe 62, and an orifice 65 connected to the cylinder 59 are provided. The connecting portion 20d is located below the rotating shaft 20f of the forward tilting door 20.

In the third embodiment, the monitoring center simultaneously sends a fire signal to the simplified fire hydrant device and the receiving unit of the hydraulic cylinder mechanism.
When the receiving unit of the hydraulic cylinder mechanism receives the fire signal, the control unit is driven and the electromagnetic valve 64 is opened.

  If it does so, since fire extinguishing water is supplied in the cylinder 59 from a water supply main pipe, the piston 58 will slide and the connection part 20d of the front leaning door 20 will be pulled up. Therefore, since the upper end part of the forward tilting door 20 rotates forward, the forward tilting door 20 can be reliably opened even if the forward tilting door 20 is stuck with exhaust gas or dust and is not easily opened.

  Further, after the end of the water discharge, after confirming that the hose is accommodated in the hose accommodating portion 16 with an ITV camera (not shown) or the like, a restoration signal is transmitted from the monitoring center. When the receiving unit of the hydraulic cylinder mechanism receives the restoration signal, the control unit is driven and the electromagnetic valve 64 is sealed. Then, the fire extinguishing water in the cylinder is drained outside the container through the orifice 65 by the restoring force of the spring 61 in the cylinder.

  Furthermore, the piston 58 slides and pushes down the connecting portion 20d of the forward tilt door 20. Therefore, since the upper end part of the forward leaning door 20 rotates in the direction of the cabinet 13, the forward leaning door 20 can be automatically closed.
