Description

  TECHNICAL FIELD The present invention relates to a tunnel emergency facility that performs evacuation guidance using a speaker provided in a fire hydrant facility that allows a hose to be removed by raising a hose storage portion.

  Conventionally, fire hydrant equipment has been provided as emergency equipment for tunnels installed in tunnels such as expressways and motorway roads. The fire hydrant equipment has a nozzle at the tip of the fire hydrant storage part of the housing with a fire hydrant door that can be opened freely. For example, two fire extinguishers are housed in a fire extinguisher housing section having a fire extinguisher door that can be freely opened and closed.

  Such a fire hydrant installation is installed at intervals of, for example, 50 meters along the side wall facing the observer passage provided in the tunnel. The supervisor passage is provided as a side wall passage that is about 1 meter higher than the road surface, and it is possible to inspect various devices including fire hydrants installed safely in the tunnel without hindering vehicle traffic in the tunnel. It is said.

  When a vehicle accident involving a fire occurs, users such as the driver of the accident vehicle open the fire hydrant door of the fire hydrant equipment, pull out the hose with a nozzle, and operate the fire hydrant valve opening / closing lever to operate the fire pump equipment. Fire extinguishing work can be performed by starting and discharging water.

  In addition, in order to protect humans and vehicles from fire accidents that occur in the tunnel, a fire detector for monitoring fire is installed and connected to a signal line drawn from the disaster prevention reception board.

  The fire detector has monitoring areas in both the left and right directions, and, for example, 25 m intervals or 50 m so that the monitoring areas with the adjacent fire detectors overlap each other along the longitudinal direction of the tunnel. It is arranged continuously at intervals.

  In addition, a guidance facility is installed which has a guidance display board showing the direction and distance of the tunnel exit and the evacuation communication entrance.

  However, in such a conventional hydrant installation installed in the tunnel, it was installed along the tunnel side wall facing the observer passage. It is necessary to reach out to the fire hydrant equipment installed on the side wall of the tunnel beyond the passage, open the fire hydrant door, pull out the hose to perform fire extinguishing work, and the fire hydrant equipment is installed at a high position away from the road surface Some people may have to go up and operate the guard passage without reaching their hands, and some guard passages are equipped with handrails that interfere with fire fighting operations and are difficult to handle. There was a case.

  In order to solve this problem, the present applicant has proposed a lift-type fire hydrant facility that can be easily and easily handled from the road side and the supervisor passage side. The elevating type fire hydrant equipment has a hose housing part in which a hose with a nozzle is housed so that it can be moved up and down by an elevating mechanism in the surveillance passage. When a vehicle accident involving a fire occurs in the tunnel, a predetermined switch When the operation is performed, the hose storage part is lifted and held at the exposed position on the supervisor passage by the operation of the lifting mechanism, and the hose storage part exposed on the supervisor passage is not required to open the fire hydrant door. The fire can be extinguished simply and easily by pulling out the hose with a nozzle.

  In addition, the lift-type fire hydrant equipment is equipped with a speaker, and when the hose storage part is lifted by the lift mechanism and exposed on the supervisor passage, an alarm sound is output from the speaker to alert the people around it. I try to let them.

  On the other hand, the guidance equipment installed in the conventional tunnel only has a guide display plate installed to indicate the direction and number of distances of the exit and evacuation connection mine, and a fire has occurred in the tunnel. In this case, for example, if the visibility inside the tunnel becomes poor due to smoke generated by a fire, it may be difficult to visually recognize the guidance display plate, and it may be difficult to perform quick and appropriate evacuation guidance.

  The present invention makes it possible to promptly and safely evacuate by accurately transmitting information such as the direction and distance of the evacuation site in the tunnel by using a voice alarm function by a speaker provided in a lift-type fire hydrant facility. It aims to provide the emergency equipment for tunnels.

(Tunnel emergency equipment)

(Warning sound when hose compartment rises)
The evacuation guidance control unit outputs a predetermined warning sound or warning message from the directional speaker when the hose storage unit of the fire hydrant equipment is raised by the lifting mechanism.

(Basic effect)
The present invention relates to a tunnel emergency facility, in which a hose storage portion containing a hose with a nozzle that is installed at a predetermined interval in the longitudinal direction of the tunnel and is stored in a supervisor passage is used when a fire hydrant is used. Fire hydrant equipment that is raised and held at an exposed position on the supervisor passage by the operation of the directional speaker, and a directional speaker that is arranged with a directivity direction set in a direction intersecting the supervisor passage for each installation location of the fire hydrant equipment, When an evacuation guidance control signal is received from the disaster prevention reception board, there is an evacuation guidance control unit that outputs a predetermined evacuation guidance message to the evacuation site in the tunnel from the directional speaker, which causes a fire in the tunnel When a vehicle accident occurs and you evacuate through a supervisory passage, when you pass in front of a fire hydrant facility installed at a predetermined interval, an evacuation area such as an evacuation port from an directional speaker Listen to the evacuation guidance message to guide you to, for example, know the distance or distance and direction from the current position to the evacuation site, and can confirm the evacuation site even in a confused situation due to a fire, so calm evacuation behavior Is possible. Also, even if there is a smoke layer in the tunnel and the visibility is poor, it is possible to listen to the evacuation guidance message so that appropriate evacuation behavior is possible.

(Effects of plane wave speakers)
In addition, the directional speaker is a plane wave speaker that outputs acoustic vibrations as a plane wave, so the sound of the evacuation guidance message is not diffused like a spherical wave by a conventional speaker, but in a limited range in the direction crossing the supervisor passage Can be heard clearly when crossing in front of a plane wave speaker, and even if directional speakers are placed in a fire hydrant facility installed at a predetermined interval, the content of Different evacuation guidance messages can be heard clearly. In addition, since the sound waves go straight without diffusing, the evacuation guidance message can be heard clearly without being affected by ambient noise without increasing the volume.

(Effects of array speakers)
In addition, since the directional speaker is an array speaker in which sound sources are arranged in a straight line in the horizontal direction, the sound of the evacuation guidance message propagates in a fan shape in the vertical direction, and a person who is at the same position in the tunnel longitudinal direction as the array speaker The sound of the evacuation guidance message can be heard regardless of the position in the short direction, and the distance to the evacuation site in the longitudinal direction can be heard clearly. In addition, since the propagation beyond the horizontal width of the array speaker becomes poor in the horizontal direction, even if the array speaker is arranged in a fire hydrant facility installed at a predetermined interval, evacuation guidance messages with different contents can be transmitted without interfering with each other. I can hear it clearly.

(Effect of evacuation guidance message)
In addition, the evacuation guidance control unit is configured to repeatedly output an evacuation guidance message indicating the distance to the evacuation site or the direction and direction from the directional speaker, so that the evacuation guidance control unit is provided for each fire hydrant installed in the supervisor passage at predetermined intervals. When you pass in front of a directional speaker, you can know and confirm the distance or distance to the evacuation site and its direction, and know the remaining distance, so you can confirm that you are approaching the evacuation site. Gives a sense of security and enables calm evacuation behavior.

(Effects of evacuation guidance messages depending on the location of the fire)
In addition, the evacuation guidance control unit repeatedly outputs an evacuation guidance message indicating the distance or distance and direction from the directional speaker to the evacuation site located in the direction away from the fire occurrence site when it is close to the fire occurrence site in the tunnel. When it is far from the fire occurrence place in the tunnel, an evacuation guidance message indicating the distance or distance and direction to the evacuation place located at the shortest distance is repeatedly output from the directional speaker.

  When the evacuation guidance control unit repeatedly outputs an evacuation guidance message indicating the distance or distance and direction to the evacuation site located away from the fire occurrence site in the tunnel from the directional speaker, Prevents evacuation behavior toward a dangerous evacuation site close to the fire occurrence location, and when away from the fire occurrence location, it can be promptly evacuated by guiding to the evacuation location of the shortest distance.

(Effects of direction display device)
In addition, for each installation location of the fire hydrant equipment, a direction display device that can selectively display the evacuation direction that is the tunnel up or down direction is arranged, and the evacuation guidance control unit is close to the fire occurrence place in the tunnel The direction display device displays the direction away from the fire occurrence location, and repeatedly outputs an evacuation guidance message indicating the distance to the evacuation location located in the evacuation direction displayed on the direction display device from the directional speaker. If it is far from the fire occurrence location, the direction display device displays the direction of the evacuation location located at the shortest distance, and an evacuation guidance message indicating the distance to the evacuation location located in the evacuation direction displayed on the direction display device. Because it is made to output repeatedly from the directional speaker, the evacuation guidance message from the directional speaker confirms the evacuation direction. In some cases, the direction display device indicates the evacuation direction with arrows, for example, and when it is close to the fire, it can reliably prevent evacuation to a dangerous evacuation area near the fire. If you are away from the place of occurrence, you can evacuate quickly by reliably guiding you to the evacuation site with the shortest distance.

(Effect of warning sound when hose housing is raised)
Further, since the evacuation guidance control unit outputs a predetermined alarm sound or warning message from the directional speaker when the hose housing part of the fire hydrant equipment is raised by the elevating mechanism, the so-called elevating fire hydrant equipment has the hose housing part. It is equipped with a voice output function that has a voice output circuit and a speaker that emits an alarm sound when raising the volume, and the speaker is a directional speaker. It is possible to easily and easily realize an evacuation guidance function in a tunnel by voice without applying a sound.

  In addition, an alarm sound is output when the hose housing is raised from the directional speaker, and does not diffuse like a spherical wave by a conventional speaker, but propagates to a limited range in the direction crossing the observer's passage. The situation where the person near the facility is alerted and the hose housing part suddenly starts to lift while the person is on the hose housing part is avoided, and safety is improved.
