[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a fire hydrant device having a nozzle sensor.

[0002]

2. Description of the Related Art As shown in FIG. 10, a fire hydrant device 3 is provided on a side wall of an inspection path 2 of a tunnel 1. FIG. The foam fire hydrant 8 and the like of the fire hydrant device 3 are accommodated in a housing 4 with a forward-sloping door. A nozzle holder for supporting the nozzle is provided on the back surface of the door. When a fire occurs in the tunnel 1, the driver 7 descends on the road 6 to approach the fire hydrant device 3, opens the forward-sloping door, opens the main valve of the fire hydrant, and removes the nozzle attached to the nozzle holder. Take out and extinguish fire.

[0003]

In the conventional fire hydrant device, for example, when the door is opened, the nozzle holder stands up and the nozzle is easily taken out. And this nozzle holder
When the nozzle is pulled out from the nozzle, the hose is fed out while meandering on the back surface of the front tilting door.

[0004] In view of the above circumstances, it is an object of the present invention to detect whether or not a nozzle is held in a nozzle holder.

[0005]

According to a first aspect of the present invention, there is provided a fire hydrant device having a nozzle holder provided on a door of a housing, the nozzle holder having a nozzle sensor for detecting the presence or absence of a nozzle , and the nozzle sensor being provided with a nozzle sensor. Drive in conjunction with the nozzle sensor
A fire sensor device connected to a fire-controlled hydrant device.
In a fire hydrant device provided with a nozzle holder on the back surface of a door of a housing, the nozzle holder includes a flat base, and a nozzle holding hole formed from a front end to a rear end of the base. in addition, the nozzle sensor fire hydrant apparatus characterized by a distal end facing the nozzle holding hole, and means for urging the tip portions toward the center of the hole, a nozzle sensor consisting provided in, is there.

[0006]

When the door is opened and the nozzle is pulled out from the nozzle halter in the event of a fire or the like, the front end of the nozzle sensor moves toward the center of the nozzle holding hole due to the urging of the rear end of the nozzle sensor. Therefore, it is possible to detect that the nozzle is not held. Further, when the nozzle is pushed toward the entrance of the nozzle holding hole, the front end of the nozzle sensor moves away from the center against the bias of the rear end. Therefore, it can be detected that the nozzle is held.

The spring 145 interposed between the spring 21 and the wire guide 146 is a spring interposed between the wire guide 146 and the interlocking latch 123. The spring 145 has a smaller spring constant than the spring 140.

Next, the operation of this embodiment will be described.
When a driver or the like approaches the inspection path and pulls the flat handle 113 when a fire or the like occurs, the latch 112 is pulled via the latch cable 109.
14 and the door 111 opens. At this time, the crank arm 117 is connected to the tension bar 130 via the interlocking latch 123.
Arrow A by the tension holder 125 fixed to
117 and rotate.
17 becomes the state of the chain line 117A. At this time, as shown in FIG. 1, the sliding lot 105 of the nozzle arm 118 moves on the guide rail 106, engages with the stopper 107 and stops, and the tip 118b of the nozzle arm 118 is indicated by a chain line in FIG. As shown, the nozzle holder 12
0 becomes the state of the chain line 120A. That is, the nozzle holder 1
20 moves in the direction of arrow A120 and changes from the state shown in FIG. 3 to the state shown in FIG. 4, so that the nozzle 20 can be easily taken. In this state, the nozzle 41 is connected to the holder 12
While pulling out from zero, pull out the inner-wound hose 42 and carry it to the fire spot to start fire fighting.

As shown in FIGS. 5 and 6, when the nozzle 41 comes off from the nozzle holding hole 120a of the nozzle holder 120, the nozzle sensor 121 rotates by the bias of the spring 140, and as shown in FIG. Since the distal end portion 121a is lowered and moves toward the center of the nozzle holding hole 120a, the interlocking latch 123 is rotated via the interlocking wire 122, and the engagement between the tension holder 125 and the tension bar 130 is released. Therefore, the tension holder 125
Can move irrespective of the tension bar 130, so that the crank arm 117 rotates in the opposite direction to the above. At this time, the nozzle arm 118 is
2 slowly returns to the original state under the action of FIG.
State. The above operation has been described for the case where the door is tilted forward, but a door that opens sideways may be used as long as means for urging the nozzle arm 118 is provided.

After the fire extinguishing operation, when the nozzle 41 is inserted into the holding hole 120a of the nozzle holder 120, the outer periphery of the nozzle 41 comes into close contact with the inner surface of the nozzle holding hole 120a, and the tip 121a of the nozzle sensor 121 is pushed up. The portion 121b rotates against the elasticity of the spring 140. Therefore, the interlocking wire 122 is loosened and the interlocking latch 123 is rotated by being pressed by the spring 145, and the key portion 123A is engaged with a latch hole (not shown) of the tension holder 125 and the tension bar 130 to fix both. In this state, the front tilting door 111 is slowly raised, and the door of the fire hydrant device 110 is closed. What
, In the same manner as in the above nozzle arm 118, fire plug the main valve 3
7 is also controlled in conjunction with the nozzle sensor 121.
It may be controlled. The embodiment of the present invention is not limited to the above. For example, a normal fire hydrant device may be used instead of the foam hydrant device.

[0014]

According to the present invention, as described above, the nozzle sensor is provided on the nozzle holder , and the nozzle sensor is further provided with the nozzle sensor.
Connected a device that is driven and controlled in conjunction with the
In, it is possible to detect whether the nozzle in the nozzle holding hole is held, apparatus for driving and controlling the nozzle sensor the presence or absence of the nozzle, for example, undulating freely nozzle arm and hydrant switches the main valve It can be used as control.
