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.

  The fire extinguishing equipment of the present invention includes a fire extinguishing agent releasing means for releasing a fire extinguishing agent at the time of a fire, and a warning display means for displaying a warning by using the pumping force of the fire extinguishing agent when the extinguishing agent is released by the extinguishing agent releasing means. And the warning display means is swelled by the compressed gas jetting means for jetting the compressed gas and the compressed gas jetted by the compressed gas jetting means. It is characterized by comprising a bag body.

  The fire warning display method of the present invention is characterized in that a bag body is inflated by using a pumping force of a fire extinguishing agent that releases the extinguishing agent at the time of a fire, and a warning is displayed by the swelled bag body. And

  In these inventions, a fire is detected and an automatic valve or a manual valve of the extinguishing agent releasing means is opened to release a fire extinguishing agent such as water or before the extinguishing agent is released. The compressed gas can be ejected by the compressed gas ejecting means of the warning display means by using the pumping force, and a bag body such as a balloon can be inflated with this compressed gas. A warning can be displayed to the person by making the person aware of the swelled bag body or by recognizing characters or victograms written on the bag body.

  As a result, it becomes possible to automatically display a warning display when the fire extinguishing equipment is started, and to make it possible for a person to recognize that a fire has occurred or that a fire extinguishing agent is discharged. It is possible to ensure that safe actions are taken.

  In the fire extinguishing equipment and the fire warning display method of the present invention, when a fire has occurred and this fire extinguisher is discharged by detecting this, a warning can be displayed using the pumping force of the fire extinguishing agent.

  Thereby, it becomes possible to make a person recognize by warning that a fire extinguisher is discharged or that a fire has occurred.

It is a figure showing fire extinguishing equipment concerning one embodiment of the present invention. It is a figure which shows the warning display means of the fire extinguishing equipment which concerns on one Embodiment of this invention. It is a figure which shows the example of a change of the warning display means of the fire extinguishing equipment which concerns on one Embodiment of this invention. It is a figure which shows the example of a change of the warning display means of the fire extinguishing equipment which concerns on one Embodiment of this invention.

  Hereinafter, with reference to FIG.1 and FIG.2, the fire extinguishing equipment and the warning display method at the time of fire which concern on one Embodiment of this invention are demonstrated.

  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.

  Moreover, in this embodiment, this warning display means 2 is arrange | positioned by attaching to the automatic valve storage box 1a (and fire hydrant) installed in the side wall part (wall part) of the tunnel M, for example, or incorporating. .

  As shown in FIG. 2, the warning display means 2 is a compressed gas that causes a compressed gas to be ejected while a pressure-feeding force (discharge pressure of the fire extinguisher P) is applied when the extinguishing agent P is released by the extinguishing agent releasing means 1. It comprises a jetting means 3 and a bag body 4 that is supplied with the compressed gas jetted by the compressed gas jetting means 3 and bulges.

  Specifically, the warning display means 2 of the present embodiment is provided in communication with the rear end side or the primary side (primary pressure side) of the automatic valve in the pipe between the automatic valve for spraying of the fire extinguishing equipment A and the spraying head. The cylinder 5 is accommodated in a cylinder 5, a piston 6 provided to be movable in the front-rear direction while being divided into a rear chamber 5 a and a front chamber 5 b communicating with the inside of the cylinder 5, and a chamber 5 b in front of the cylinder 5. The pyrotechnics 7 of the compressed gas ejection means 3 provided in this manner, the frictional contact portion 8 of the compressed gas ejection means 3 provided in front of the pyrotechnics 7 of the cylinder 5, and the front end side of the cylinder 5 are covered. And a bag body 4 provided integrally therewith.

  The cylinder 5 is provided with a fire extinguishing agent introduction port 5c for communicating the piping of the fire extinguishing agent P and the rear chamber 5a on the rear end side, and a gas jet opening for communicating the front chamber 5b and the inside of the bag body 4 on the front end side. 5d is provided.

  The bag body 4 is made of, for example, a synthetic resin material having high elasticity, and is stored in a folded state during normal times. In addition, the bag body 4 may be provided not only with one but with two or more.

  And in the fire extinguishing equipment A (and fire warning display method) of this embodiment which consists of the said structure, a fire is detected, the automatic valve of the fire extinguishing equipment A and a manual valve are opened, and fire extinguishing agents P, such as water, are opened. When discharged, the extinguishing agent P is supplied to the chamber 5 a behind the cylinder 5, and the pumping force (discharge pressure) of the extinguishing agent P acts on the piston 6.

  As a result, the piston 6 is pushed forward vigorously, and the pyrotechnic 7 is pushed forward by the piston 6. At this time, the pyrotechnic 7 is ignited by rubbing against the rubbing portion 8 provided in the chamber 5b in front of the cylinder 5, and gas (compressed gas) is rapidly generated.

  And the gas generated with the ignition of the pyrotechnics is ejected from the gas outlet 5d, and the bag body 4 is inflated and swelled forward as shown in FIG. Thereby, the road user recognizes that an abnormality such as a fire has occurred by recognizing the swollen bag body 4. In addition, if the bag 4 is marked with a letter such as “Fire is out !, Stops !, Will be discharged!” Or Victorgram, road users will be more sure that a fire has occurred and the water will be discharged. Can be recognized.

Further, by the delay mechanism for delaying the 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 bag body 4 bulges and a warning is displayed as described above.
For example, the delay mechanism causes the water (pressurized water) of the fire extinguishing agent P to be supplied (acted) to the warning display means 2 before the automatic valve of the fire extinguisher discharging means 1, and the bag body 4 bulges and a warning is displayed. It is only necessary to supply the fire extinguishing agent P to the automatic valve after a predetermined time has elapsed so that the automatic valve is activated to release the fire extinguishing agent P.
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.

  Here, when the warning display means 2 is built in the automatic valve storage box 1a or the fire hydrant (fire hydrant storage box), for example, a door that can be opened and closed using a hinge or the like is provided, and the bag body 4 swells. At this time, the door may be pressed and automatically opened so that the bag body 4 bulges outside.

  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 or the manual valve of the fire extinguisher releasing means 1 is opened and the fire extinguishing agent P such as water is released. Alternatively, before the extinguishing agent P is released, a gas (compressed gas) is ejected by the compressed gas ejecting means 3 of the warning display means 2 using the pumping force of the extinguishing agent P, and a balloon (balloon) is used with this gas. The bag body 4 can be bulged. A warning can be displayed to the person by making the person aware of the bulged bag body 4 or by recognizing characters or victograms written on the bag body 4.

  As a result, the fire extinguishing equipment A can be activated and a warning display can be automatically issued, allowing a person to recognize that a fire has occurred and the extinguishing agent P is released. And it is possible to encourage them to take safe actions.

  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, if the bag body 4 is inflated using the pumping force of the fire extinguishing agent P, and if a full-scale water discharge is performed from the automatic valve after a certain delay time has elapsed, the bag body 4 is effective. It becomes possible to make a water discharge notice.

  Further, since the warning is displayed on the swelled bag body 4, for example, even when the vehicle comes into contact with the bag body 4, the bag body 4 is light and soft, so that it does not lead to an accident.

  As mentioned above, although one embodiment of the fire extinguishing equipment A and the fire warning display method according to the present invention has been described, the present invention is not limited to the above embodiment, and can be appropriately changed without departing from the spirit of the present invention. It is.

Hazardous gas danger! No entry!", "Fire! Explosion danger! No entry! A warning such as “!” May be displayed.
In addition, when a fire occurs in an underground parking lot, an underground passage, or the like, a warning such as “A fire has occurred! Do not enter!” May be displayed by the pumping power of the extinguishing agent P.
Further, 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.

Moreover, the fire extinguisher discharge | release means 1 concerning this invention is not restricted to the automatic valve apparatus (automatic water spray equipment) provided with the piping which pumps the fire extinguisher P, the automatic valve for spraying, a spraying head (spraying nozzle, sprinkler), etc. It may be a fire hydrant. In other words, any extinguishing agent releasing means 1 according to the present invention can be applied as long as it extinguishes the extinguishing agent P in a fire.
Moreover, it is not necessary to limit the fire extinguishing agent P concerning this invention to water.

  And when performing fire extinguishing activity using a fire hydrant, the occurrence of an accident can be transmitted to other drivers and the like by using the fire hydrant and the bulging bag body 4. Thereby, it becomes possible for the operator of the fire hydrant to perform fire extinguishing activities safely and safely.
