Description

  The present invention relates to fire extinguishing equipment.

  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, an object of the present invention is to provide a fire extinguishing facility that makes it possible to reliably recognize the occurrence of a fire, the start of watering, etc., and to effectively take appropriate safety actions.

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

  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 fire extinguishing equipment 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. Further, in the present embodiment, the warning display means 2 is provided on a ceiling portion such as a side wall portion (wall portion), an arch portion, or a ceiling plate portion of the tunnel M, and includes a screen 3 on which a warning is written. The screen 3 is configured to open while the pumping force is applied.

  Specifically, as shown in FIGS. 2 and 3, the warning display means 2 of the present embodiment is connected to the side wall portion and the ceiling portion of the tunnel, the fixed portion 4a, and the fixed portion 4a, and extends in the lateral direction T2. A frame 4 composed of a support portion 4b, a shaft portion 5 that is supported by the frame body 4 so that the direction of the axis O1 is oriented in the horizontal direction T2 and is rotatable about the axis O1, and one end is fixed to the shaft portion 5 The screen 3 wound around the part 5, supported by connecting one end to the frame 4, and advanced / retracted in the vertical direction T <b> 1 orthogonal to the axis O <b> 1, the other end of the screen 3, And advancing and retracting members 7 supported by being connected to the ends.

  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 or the extinguishing agent P is released.

  The screen 3 of the present embodiment is formed by providing a flexible tubular structure (tube) 8 at least partially. Further, the tubular structure 8 is provided with a plurality of extinguishing agent discharge holes for discharging the extinguishing agent P onto the surface of the screen 3 when the extinguishing agent P such as water is supplied into the tubular structure 8.

  On the other hand, the advancing / retreating mechanism 6 of the present embodiment is connected to the rear end side or the primary side (primary pressure side) of the automatic valve, for example, in the pipe between the spraying automatic valve and the spraying head of the extinguishing agent discharge means 1. One end of the cylinder 9 is connected to the piston 10, the piston 10 is provided in such a manner that the cylinder 9 is divided into a rear chamber 9a and a front chamber 9b communicating with the pipe, and is movable in the front-rear direction S1. And a piston rod 11 protruding forward from the front end of the cylinder 9 from the front chamber 9b along the axis O2 and connected to the advance / retreat member 7. In this embodiment, the advancing / retreating mechanism 6 is provided on each of the left and right end portions with the shaft portion 5 (with a built-in spring wound in the screen storage direction) interposed therebetween.

  Further, each advancing / retracting mechanism 6 is built in a chamber 9b in front of the cylinder 9 so that a spring 12 biases the piston 10 rearward. Thereby, at the normal time, the piston 10 is arranged on the rear end side, the piston rod 11 is accommodated in the front chamber 9b, and the advance / retreat member 7 is arranged close to the front end of the cylinder 9. .

  Furthermore, in this embodiment, the end of the tubular structure 8 of the screen 3 is connected to the cylinder 9 of each advance / retreat mechanism 6 so that the inside of the tubular structure 8 and the inside of the cylinder 9 communicate with each other. At this time, when the screen 3 is closed, the inside of the tubular structure 8 and the chamber 9b in front of the cylinder 9 communicate with each other. When the screen 3 is opened, the inside of the tubular structure 8 and the cylinder 9 are communicated. The rear chamber 9a is configured to communicate with each other. In other words, when the thickness of the piston 10 is d and the distance from the front end of the cylinder 9 to the connecting portion 8a of the tubular structure 8 is d1, d1> d is satisfied.

  And in fire extinguishing equipment A of this embodiment which consists of the said structure, if it detects that a fire has occurred, the automatic valve of the fire extinguishing agent discharge | release means 1 will open, and the water as the fire extinguishing agent P will be pumped to piping. .

  At this time, since the rear chamber 9a of the cylinder 9 of the advance / retreat mechanism 6 communicates with this pipe, the water of the extinguishing agent P is also pumped into the rear chamber 9a, and the piston 10 is pressed forward. As a result, the piston rod 11 of the pair of advance / retreat mechanisms 6 advances forward (downward).

  Since the piston rod 11 is connected to the advance / retreat member 7 and the screen 3 is connected to the advance / retreat member 7, when the piston rod 11 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. This opens a screen with letters and victograms such as “Fire !! Stop!

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.

  On the other hand, in the fire extinguishing equipment A of the present embodiment, when the piston 10 moves to the front end side of the cylinder 9 and reaches the position where the screen 3 opens, the chamber 9a behind the cylinder 9 and the inside of the tubular structure 8 of the screen 3 are connected. In communication, water of the extinguishing agent P is supplied into the tubular structure 8. As a result, the extinguishing agent P is supplied to the surface of the screen 3 from the extinguishing agent discharge hole of the tubular structure 8, and the open screen 3 has an excellent heat resistance because the extinguishing agent P circulates inside the tubular structure 8. Demonstrate fire resistance.

  Therefore, in the fire extinguishing equipment A of the present embodiment, when a fire is detected and the automatic valve or the manual valve of the fire extinguisher discharging means 1 is opened and the fire extinguishing agent P such as water is released, or the fire extinguishing agent P Before being released, the pumping force of the fire extinguishing agent P acts and the screen 3 can be opened, and a warning such as letters or victograms written on the screen 3 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.

  Further, a fire extinguishing agent P such as water is supplied to the inside of the tubular structure 8 constituting the screen 3, and the fire extinguishing agent P is discharged from the fire extinguishing agent discharge hole and supplied to the surface of the screen 3, whereby the heat resistance of the screen 3 is increased. And fire resistance can be improved. Thereby, even if the screen 3 is heated by a fire, the screen 3 can be reliably held in a state where a warning is displayed for a desired necessary time.

  Furthermore, since the heat resistance and fire resistance of the screen 3 can be improved, it is also possible to exert smoke shielding / heat shielding / flame shielding effects and fire spread preventing effects by adjusting the arrangement and size of the screen 3. become. This makes it possible to extend the evacuation time.

  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 released by the extinguishing agent releasing means 1, the pumping force continues to act on the warning display means 2, 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.

  Moreover, in the fire extinguishing equipment A of this embodiment, the warning display means 2 is provided on the ceiling, so that the visibility of the warning displayed by the warning display means 2 can be increased, and tunnel users, etc. It becomes possible to recognize the warning to the person of. Furthermore, since the warning display means 2 is provided on the ceiling, the screen 3 as the warning display means 2 can be configured to open using its own weight (gravity).

For example, in this embodiment, although it demonstrated as what applies the fire extinguishing equipment A concerning this invention with respect to a tunnel fire, this invention is applicable to all facilities.
For example, the fire extinguishing equipment A of the present invention is installed in a chemical factory, and when a fire breaks out, the fire-extinguishing agent P pumps the power to "fire! 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.

In this connection, the fire extinguishing agent releasing means 1 according to the present invention includes an automatic valve device (automatic water device) including a pipe for pumping out the fire extinguishing agent P, an automatic valve for spraying, a spraying head (spraying nozzle, sprinkler) and the like. Not only spraying equipment) but also a fire hydrant may be used. 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.

  Further, if the tubular structure 8 is provided so that the heat resistance is ensured with respect to the condition of heating the screen 3 at 900 ° C. for 60 minutes (heating condition conforming to the standard heating temperature curve), a highly reliable warning display means. 2. Eventually, the fire extinguishing equipment A can be obtained.

  Next, with reference to FIGS. 4-6, the fire extinguishing equipment which concerns on 2nd Embodiment of this invention is demonstrated.

Here, as in the first embodiment, when the fire occurs in the tunnel M, the present embodiment reliably uses the road to warn the user that the fire extinguisher P is released or that a fire has occurred. It is related to fire extinguishing equipment A that makes it possible to recognize the safety of road users.
Therefore, in this embodiment, the detailed description of the same configuration as that of the first embodiment is omitted as appropriate.

  As shown in FIG. 4, the fire extinguishing equipment A of the present embodiment detects a fire in response to a signal from an automatic reporting facility such as a fire detector or a manual reporting facility such as a push button reporting facility as in the first embodiment. The fire extinguishing agent releasing means 1 for releasing the extinguishing agent P such as water, and a warning display for displaying a warning by using the pumping force of the extinguishing agent P when the extinguishing agent P is released by the extinguishing agent releasing means 1 And means 2.

  On the other hand, as shown in FIGS. 4, 5, and 6, the warning display means 2 of the present embodiment is formed using a tubular structure 8 in which most of the screen 3 on which warnings are written by characters, victograms, or the like. Yes. That is, in this embodiment, the screen 3 is formed by arranging the tubular structures 8 side by side in the vertical direction and the horizontal direction, and communicating the adjacent tubular structures 8 with each other. Further, for example, the supply port and the discharge port are provided in the tubular structure 8 on the outermost side (uppermost and lowermost, or leftmost and rightmost).

  In the fire extinguishing equipment A of the present embodiment, when it is detected that a fire has occurred, the automatic spraying valve of the fire extinguishing agent releasing means 1 opens, and water as the fire extinguishing agent P is sprayed with the automatic spraying valve and the spraying head. The fire extinguishing agent P is pumped and supplied to the supply port of the screen 3 from this pipe.

  Therefore, also in the fire extinguishing equipment A of the present embodiment, when a fire is detected and the automatic valve or the manual valve of the fire extinguisher discharging means 1 is opened and the fire extinguishing agent P such as water is released, or the predetermined start of water discharge Before the time, the pumping force of the extinguishing agent P acts and the screen 3 can be opened, and a warning such as letters or victograms written on the screen 3 can be displayed.

  As a result, the fire extinguisher discharge means 1 releases the fire extinguisher P and can automatically issue a warning display. The warning display indicates that a fire has occurred to the person, the fire extinguisher P is released, etc. It can be recognized. Therefore, it is possible to promptly take safe actions as compared with the conventional case.

  Further, the heat resistance and fire resistance of the screen 3 can be improved by supplying the fire extinguishing agent P such as water into the tubular structure 8 constituting the screen 3. Thereby, even if the screen 3 is heated by a fire, the screen 3 can be reliably held in a state where a warning is displayed for a desired necessary time.

  Furthermore, since the heat resistance and fire resistance of the screen 3 can be improved, it is also possible to exert smoke shielding / heat shielding / flame shielding effects and fire spread preventing effects by adjusting the arrangement and size of the screen 3. become.

  Therefore, it is possible to obtain the same effect as that of the first embodiment.

In addition, it is possible to exhibit more excellent smoke shielding / heat shielding / flame shielding effect and fire spread preventing effect.

  Furthermore, a fire extinguishing agent discharge hole may be formed in the tubular structure 8 so that the fire extinguishing agent P supplied to the inside of the tubular structure 8 exits the fire extinguishing agent discharge hole and is supplied to the surface of the screen 3. In this case, it is possible to make the screen 3 further excellent in heat resistance and fire resistance. Therefore, it is possible to ensure a state in which a warning is displayed on the screen 3 for a desired necessary time even when the screen 3 is heated by a fire even more reliably and effectively. In addition, it is possible to exhibit a further excellent smoke shielding / heat shielding / flame shielding effect and fire spread preventing effect.

  As mentioned above, although 2nd Embodiment of the fire extinguishing equipment concerning this invention was described, this invention is not limited to said 2nd Embodiment, It does not deviate from the meaning including the example of a change of 1st Embodiment. The range can be changed as appropriate.

  For example, as shown in FIG. 7, a plurality of tubular structures 8 are communicated to form the screen 3, and a tubular structure that is extendable outward (uppermost and lowermost, or leftmost and rightmost). 13 may be provided to form the screen 3.

Examples of the telescopic tubular structure 13 include the following.
The tubular structure 13 is formed by a two-layer structure of a watertight layer provided on the water passage surface in direct contact with water of the fire extinguisher P and a cover layer provided outside the watertight layer.
For the watertight layer, if the length of the unloaded state is 1, for example, a synthetic rubber extending at least 1.5 to 8 times in a loaded state of 1 MPa when the extinguishing agent P is pumped, a hose rubber made of synthetic resin, etc. It is preferable to use it.
The cover layer is preferably a fiber or a synthetic resin that is integrally covered on the outside of the watertight layer and extends, for example, 1.5 to 8 times under load. Moreover, when using a fiber as a raw material of a cover layer, it is preferable to set it as the knitting structure by the diameter yarn and weft which extend 1.5 to 8 times in a load state. Furthermore, as such a fiber, for example, trade name “Spybar” manufactured by Spyber Inc. may be mentioned.
