Description

[Detailed Description of the Invention] The present invention relates to a fire hydrant incorporating an audio guidance device.

Fire hydrants installed in buildings, etc. generally have operating instructions written on the back side of the door, etc., and those involved in extinguishing fires must read the operating instructions before using the hydrant. However, in the event of a fire, it is not desirable to take out a fire hose while reading the operating instructions, as this is an emergency job where every second counts, and there is a risk of misreading.

Therefore, a prior art technique (Utility Model Application Publication No. 56-93256) in which the operating method of a fire hydrant is recorded in advance on a magnetic tape or the like and is activated at the same time as the door of the fire hydrant is opened.
There is. However, since such prior art is not a fire hydrant that can be operated by one person,
The operation itself is not difficult; multiple fire extinguishers simply follow the voice commands. In other words, the fire hydrant itself cannot be operated by one person because the person must open the valve and hold the nozzle at the end of the hose at the same time. Therefore, the person closest to the fire hydrant must operate the fire hydrant. In other words, even if a voice command is given on how to operate a fire hydrant, if a plurality of fire extinguishers do not communicate with each other and follow the operating procedures, it will not be possible to extinguish the fire. Furthermore, since the prior art only provides audio instructions on how to operate a fire hydrant, it is not clear where in the fire scene or how to evacuate the fire.

This invention was made in view of the above circumstances,
To provide a fire hydrant incorporating a voice guidance device which enables even a single firefighter to carry out fire extinguishing activities quickly and informs other places of the situation at the scene.

Hereinafter, the present invention will be described in detail with reference to illustrated embodiments.

Fig. 1 shows an embodiment in which the present invention is applied to a fire hydrant of the type in which a hose is wound around a reel and stored in a storage box. It is a hose holder that can be changed to a predetermined direction. This hose holder 3 has a connecting rod 5 whose lower end is pivotally connected to the wall surface of the box 1.
and a support shaft 6 supported by the tip of the connecting rod 5.
and a plate member 7 whose base portion is rotatably supported by the shaft 6. Reference numeral 8 denotes a plucked strip provided on the support shaft 6, which allows the plate member 7 to be elastically opened with respect to the connecting rod 5. 9 is the above hose 4
The hose 4 is a reel that is wrapped around the reel, and two hoses 4, each of which is folded in half, are wound around each reel separately. Reference numeral 10 denotes a connecting portion that connects two hoses 4. A water discharge nozzle 11 is attached to the tip of one hose 4, and the rear end of the other hose 4 is connected to a piston-type fire hydrant valve 12.

As shown in FIGS. 2 and 3, this fire hydrant valve 12 has an L-shaped outer pipe 1 connected to a water supply port 13.
4 and an inner tube 16 which is partially slidably fitted into the cylindrical portion 15 of the outer tube 14, and is opened and closed by sliding the inner tube 16. The outer tube 14 has a claw portion 17 biased by a spring (not shown) on the inner surface of the opening end on the side of the water supply port 13, and is rotatably fitted into the water supply port 13 via the claw portion 17. There is. On the other hand, the inner tube 16 fitted into the outer tube 14 via the O-ring 18 has its tip connected to the base of the hose 4, so that when the hose 4 is pulled, it slides and opens the valve. . 19 is a pump start button.

Reference numeral 20 denotes a switching element such as a limit switch that is activated by the opening/closing operation of the door 2. When the door 2 is opened, the switching element 20 connects a sound generating device 21 (described later) to a power source such as a battery. By closing the door 2, the sound generating device 21 is cut off from the power source.

The sound generating device 21 has instructions for operating a fire hydrant recorded in advance on a magnetic tape or the like, and is configured to repeat the operating instructions, for example, about seven times, at the same time as the door 2 is opened.

For example, as shown in Figure 4, the operation method is as follows: A "Press the start button" → B "Take the water nozzle and pull out the hose holder" → C "Extend and pull the hose" in advance. It's been recorded. The operating method shall be determined as appropriate depending on the type of fire hydrant.

In addition to operating the fire hydrant, the sound generating device has a built-in means for notifying other places of the location of the fire scene, the location of evacuation equipment, and measures to be taken after a fire occurs. .

For example, if a fire breaks out near the site where a fire hydrant is being used, the location of evacuation equipment near the fire hydrant will be notified and subsequent instructions will be given.

FIG. 5 is an electrical circuit diagram of the sound generating device 21 and the switching element 20. The switching element 20 is closed when the door 2 is opened, and opened when the door 2 is closed. A sound generating device 21 is connected to a power source 22 such as a battery through this switching element 20.

Next, a case in which the above-mentioned fire hydrant is used will be explained.

When a fire occurs, when the door 2 is first opened, the switching element 20 is closed and the sound generating device 21 is connected to the power source 22. And the sound generator 2
From step 1, the operating instructions are displayed by voice, and the steps of ``Press the start button'' → ``Take the water nozzle and pull out the hose holder'' → ``Extend and pull the hose'' are repeated about 7 times. Accordingly, when the start button 19 is pressed, the pump starts to start. Next, remove the water spray nozzle 11,
When the hose holder 3 is pulled out and directed toward the fire point, the hose holder 3 faces in the direction in which the hose 4 is pulled out, and the hose 4 is unwound from the reel 9. When the hose 4 is pulled out, the fire hydrant valve 12 changes direction following the extending direction of the hose 4.
When the hose 4 is fully extended and pulled, the inner pipe 16 connected to the base of the hose 4 slides as shown in FIG. 3, and the fire hydrant valve 12 opens. Thereby, water is passed toward the water spraying nozzle 11, and water spraying work can begin.

When the fire extinguishing work is completed, the hose 4 is wound around the reel 9, the water nozzle 11 is housed in the box 1, and the door 2 is closed, the switching element 20 is opened and the power source 22 is cut off. At this time, the audio generator 21 returns to the beginning of the magnetic tape and stops. The magnetic tape may be automatically rewound after repeating the operation method about seven times, or may be rewound by closing the door 2.

Furthermore, in addition to the magnetic tape showing how to operate the fire hydrant, another magnetic tape is activated to notify other locations of the occurrence of a fire. For example, "A fire has broken out at ○○○○", "There is evacuation equipment at ○○○○",
``Please follow the instructions from the central control room'' will be broadcast from microphones on each floor.

On the other hand, microphones installed on each floor display the location of the fire site and notify the location of evacuation equipment, and guide the evacuation of ordinary people who are not involved in firefighting activities. Furthermore, for people who have difficulty understanding the fire situation, a sign will be displayed to indicate that instructions from the central control office will be followed.

As mentioned above, according to the fire hydrant of the present invention that incorporates a device that guides people by voice, water can be started by pulling out the hose, going to the fire scene, and pulling the end of the hose, so that one person can Firefighters can easily perform everything from opening the valve to discharging water. In addition, when the door opens, instructions on how to operate the fire hydrant can be displayed audibly, and at other locations, the location of the fire scene, the location of evacuation equipment, and subsequent measures can be displayed audibly. I'll come. Therefore, when carrying out fire extinguishing activities alone, there is no risk of causing anxiety to fire extinguishers at the fire site, and there is no need to cause unnecessary anxiety to people in other places. Therefore, the possibility of erroneous operation can be prevented.
