Description

  The present invention relates to a fire extinguishing equipment and a fire warning display method.

  For example, when a fire breaks out in a tunnel, it receives a signal from an automatic notification facility such as a fire detector or a manual notification facility such as a push button notification facility, and automatically uses a water spray automatic valve after a predetermined time. A water spray facility for releasing water (extinguishing agent) from the spray head all at once is provided as a main facility. This is intended to protect road users against fire, prevent the spread of fire, extinguish fires, protect tunnel bodies and equipment.

  On the other hand, we expect road users to take safety actions such as stopping the car and evacuating when a tunnel fire occurs, but in practice, avoid the fire spot without stopping the car. There are many road users trying to pass. As a result, even if a road administrator who recognizes the occurrence of a fire tries to activate the water spray facility, there is a situation in which it is not possible to sprinkle (water discharge) because of fear of the occurrence of a secondary disaster for road users who are not taking safety actions. End up.

  Contrary to this, when starting up the water spray equipment, water is sprayed with a small amount of water before full-scale watering is performed, and the stop is promoted with this small amount of watering, and then the system is shifted to full-scale watering. A water spray facility has been proposed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3).

  However, even when it is configured to spray a small amount of water before full-scale watering as described above, if the road user does not know the meaning of the small amount of watering and does not understand the function and purpose, the vehicle is stopped. There is also a risk that the operation will continue. That is, there is a possibility that the purpose of stopping the vehicle before watering is not sufficiently exhibited.

  Moreover, in the conventional water spray equipment, it is assumed that there is a time interval until full-scale watering, so that it stops in front of the watering section before moving to full-scale watering or passes (can pass) the watering section. Yes. However, there is a possibility that the car has entered the watering section in a state where it has shifted to full-scale watering. As a result, for example, full-scale watering is started in which water corresponding to a rainfall of 360 mm per hour is sprinkled. There is a risk that secondary accidents will occur.

  In view of the above circumstances, the present invention provides a fire extinguishing facility and a fire warning display method that make it possible to reliably recognize the occurrence of a fire, the start of watering, etc., and to promptly take appropriate safety actions effectively. For the purpose.

  In order to achieve the above object, the present invention provides the following means.

  As a result, the fire extinguisher is released by the fire extinguishing agent releasing means (and the fire extinguishing agent releasing means is activated), and a warning display can be automatically issued. Can be recognized. Therefore, it is possible to promptly take safe actions as compared with the conventional case.

  Moreover, in the fire extinguishing equipment of the present invention, it is desirable that the warning display by the warning display means is performed a predetermined time before the extinguishing agent is released.

  In this invention, since the fire extinguishing agent is released after a predetermined time has elapsed after the warning is displayed by the warning display means, the person recognizes the warning displayed by the warning display means and takes safety action. It becomes possible to release the fire extinguishing agent at a certain stage.

  Further, in the fire extinguishing equipment of the present invention, the warning display means includes a screen on which a warning is written, the pumping force of the fire extinguishing agent acts, and the screen opens or the screen is moved in a predetermined direction. Desirably configured to point.

  In this invention, while the pressure-extinguishing force of the extinguishing agent acts, it is possible to automatically open the screen that has been folded or wound, or to direct the screen in a desired direction. This allows people to recognize that a fire has occurred or that a fire extinguisher has been released by writing letters, victograms, etc. on the screen, and can encourage them to take safe actions without fail. become.

  Furthermore, in the fire extinguishing equipment of the present invention, it is more desirable that the warning display means is provided on the wall and / or the ceiling.

  Hereinafter, with reference to FIGS. 1 to 3, the fire extinguishing equipment and the fire warning display method according to the first embodiment of the present invention will be described.

  Here, in the present embodiment, when a fire occurs in the tunnel, it is ensured that the road user recognizes a warning such as releasing a fire extinguisher or that a fire has occurred. The present invention relates to a fire extinguishing facility and a warning display method at the time of fire that can ensure safety.

  As shown in FIG. 1, the fire extinguishing facility A of the present embodiment detects a fire upon receiving a signal from an automatic reporting facility such as a fire detector or a manual reporting facility such as a push button reporting facility. Extinguishing agent releasing means 1 for releasing the extinguishing agent, and warning display means 2 for displaying a warning by using the pumping force (discharge pressure) of the extinguishing agent when the extinguishing agent is released by the extinguishing agent releasing means 1 are provided. It is configured.

  For the extinguishing agent releasing means 1, for example, a pipe for pumping out the extinguishing agent, an automatic valve for spraying, an automatic valve device (automatic water spraying equipment) provided with a spraying head (spraying nozzle, sprinkler) and the like are applied.

  On the other hand, the warning display means 2 of the present embodiment has a predetermined interval in the length direction from one wellhead of the tunnel M to the other wellhead depending on the arrangement configuration of the fire extinguishing agent discharge means 1 and the setting condition of the fire prevention section. There are a plurality of openings. In the present embodiment, the warning display means 2 is provided along the side wall (wall) of the tunnel M, and includes a screen 3 on which a warning is written. Is configured to open.

  Specifically, as shown in FIGS. 1 and 2, the warning display means 2 of the present embodiment includes a fixed portion 4 a that is fixed to lining concrete or the like of the side wall portion of the tunnel M, and a side wall portion that is connected to the fixed portion 4 a. A frame body 4 comprising a support portion 4b extending in a substantially vertical direction T1 along the axis O1, a shaft portion 5 supported by the frame body 4 so as to be rotatable about the axis O1 with the axis O1 direction oriented in a substantially vertical direction T1, and one end Is fixed to the shaft portion 5 and is wound around the shaft portion 5, and is supported by connecting one end to the frame body 4, and is advanced and retracted in the front-rear direction S 1 toward the inner side of the tunnel M perpendicular to the axis O 1. And an advance / retreat member 7 connected to and supported by the other end of the screen 3 and the other end of the advance / retreat mechanism 6.

  On the surface of the screen 3, for example, letters such as “Fire is out! / Stop! / Water will be discharged!” And victograms etc. are written, and when this screen 3 opens, a road user (person) is fired. It is formed so that it can be recognized that fire has occurred and fire extinguishing agent is released.

  In addition, the screen 3 of the present embodiment has heat resistance against a high temperature at the time of fire, and is formed so as not to burn even when exposed to a high temperature of 900 ° C. for 60 minutes and to generate no toxic gas. It is desirable that

  As shown in FIG. 3, the advance / retreat mechanism 6 is, for example, connected to a pipe between the spray automatic valve and the spray head of the extinguishing agent discharge means 1 to the rear end side or the primary side (primary pressure side) of the automatic valve. A cylinder 8, a piston 9 provided inside the cylinder 8 to be connected to the piping, a rear chamber 8a and a front chamber 8b, which can be moved forward and backward in the front-rear direction S1, and one end connected to the piston 9 The piston rod 10 projects forward from the front end of the cylinder 8 along the axis O2 and is connected to the advance / retreat member 7. In this embodiment, the advance / retreat mechanism 6 is provided above and below the shaft 5 (with a built-in spring wound up in the screen storage direction), respectively.

  Further, as shown in FIGS. 2 and 3, each advancing / retracting mechanism 6 is built in a chamber 8 b in front of the cylinder 8 so as to urge the piston 9 backward. Thus, in a normal state, the piston 9 is arranged on the rear end side, the piston rod 10 is accommodated in the front chamber 8b, and the advancing / retreating member 7 is arranged close to the front end of the cylinder 8. .

  And in the fire extinguishing equipment A (and fire warning display method) of the present embodiment having the above-described configuration, when it is detected that a fire has occurred, the automatic valve of the fire extinguishing agent releasing means 1 is opened, Water is pumped into the pipe.

  At this time, since the rear chamber 8a of the cylinder 8 of the advance / retreat mechanism 6 communicates with the pipe, the water of the extinguishing agent P is also pumped into the rear chamber 8a, and the piston 9 is pressed forward. As a result, the piston rod 10 of the pair of advance / retreat mechanisms 6 advances forward.

  Since the piston rod 10 is connected to the advance / retreat member 7 and the screen 3 is connected to the advance / retreat member 7, when the piston rod 10 advances forward, the advance / retreat member 7 advances forward, and the screen 3 pulls on the advance / retreat member 7. As a result, the shaft portion 5 rotates around the axis O1, and the screen 3 is fed out. As a result, for example, the screen 3 on which characters such as “Fire is out!

Further, by the delay mechanism for delaying water distribution to the spray head, the water of the extinguishing agent P is discharged from the spray head after a predetermined time has elapsed since the screen 3 opened and a warning was displayed as described above.
For example, the delay mechanism causes the water (pressurized water) of the fire extinguisher P to be supplied (acted) to the warning display means 2 before the automatic valve of the fire extinguisher discharge means 1, and after the screen 3 is opened and a warning is displayed. What is necessary is just to be comprised so that the water of the fire extinguisher P may be supplied (action) to an automatic valve after predetermined time progress, an automatic valve may be started, and the fire extinguisher P may be discharge | released.
Note that the warning valve 2 and the automatic valve of the fire extinguishing agent discharge means 1 for releasing the fire extinguishing agent P are separated from each other. After the warning valve for the separate system is activated, the automatic valve of the extinguishing agent discharge means 1 is activated. It is also possible to control so that the water of the extinguishing agent P is discharged from the spray head after a predetermined time has elapsed since the warning was displayed.

  In addition, as shown in FIG. 1, from the viewpoint of preventing secondary disasters, the fire extinguishing agent releasing means 1 may be configured to be within the range of the building limit R even when the screen 3 is open. desirable.

  Therefore, in the fire extinguishing equipment A and the fire warning display method of the present embodiment, when a fire is detected and the automatic valve of the fire extinguisher discharging means 1 is opened and the fire extinguishing agent P such as water is released or water discharge starts. The warning display means 2 is activated using the pumping force of the fire extinguishing agent P a predetermined time before, for example, the screen 3 on which characters, victograms and the like are written opens and a warning can be displayed.

  As a result, the fire extinguishant P is released by the fire extinguisher releasing means 1 (and the fire extinguisher releasing means 1 is activated), and a warning display can be automatically issued. And the fact that the fire extinguishing agent P is released can be recognized. Therefore, it is possible to promptly take safe actions as compared with the conventional case.

  Moreover, while the pumping force of the fire extinguishing agent P acts, the wound screen 3 can be opened automatically. This allows people to recognize that a fire has occurred or that the extinguishing agent P has been released by writing letters, victograms, etc. on the screen 3 and prompting them to take safe actions. Is possible.

  Further, since the warning display means 2 is provided on the side wall (wall part) of the tunnel M, the visibility of the warning displayed by the warning display means 2 can be increased, and it is possible for a person such as a tunnel user. It becomes possible to recognize the warning without fail.

  Then, the warning display means 2 is activated in this manner, and a person such as a road user recognizes that a fire has occurred or that the fire extinguisher P is released, and performs a safety action such as stopping the car surely. Since it can be urged to take, it is possible to surely eliminate the inconvenience that full-scale watering cannot be performed as in the prior art. That is, the original function and purpose as the fire extinguishing equipment A (extinguishing agent discharge means 1) can be effectively exhibited.

  Furthermore, the warning display means 2 is activated by using the pumping force that discharges the fire extinguishing agent P by the fire extinguishing agent releasing means 1, so that an additional device for the warning display means 2, an addition of electrical wiring, and a control system are provided. It is possible to display a warning without making any changes. For this reason, for example, the fire extinguishing equipment A is configured as in the present embodiment without requiring a significant change not only for a new tunnel but also for an existing tunnel (not only a new facility but also an existing facility), and its operational effects. Can be granted.

  Further, by using the pumping force that discharges the extinguishant P by the extinguishing agent releasing means 1, the warning is displayed by opening the screen 3 of the warning display means 2, so that if the screen 3 is opened, a warning such as characters is displayed. Is displayed firmly and there is no inconvenience such as invisible characters. In particular, if the warning display means 2 is arranged in front of the traveling direction of the spray water discharge section, the display will not be lost due to water discharge. Furthermore, while the extinguishing agent P is being discharged by the extinguishing agent releasing means 1, the pressure force continues to act on the extinguishing agent releasing means 1, so that the screen 3 can be opened. Further, at this time, since the pumping force continues to act, it is difficult to be affected by wind and the like, and the warning display can be maintained in a stable state for a long time.
