And the extinguishing agent ejected through the nozzle 410 is discharged to the lower side of the ejection pipe 700, while being sprayed to the surroundings through the first and second extinguishing exhaust parts (712a, 722a) in the process of being discharged downward The fire is put out secondarily.

As described above, the present invention can be sprayed to a wide range of areas through the first and second fire extinguishing exhaust parts 712a and 722a as well as the local range during the injection of the extinguishing agent, which is advantageous in terms of fire suppression.

On the other hand, even if the fire extinguishing agent is ejected through the nozzle 410 or the fire does not occur as the glass valve 600 is broken due to the fire in a state in which the temperature sensor 900 is not operating normally, When the extinguishing agent is ejected through the nozzle 410 while the valve 600 is broken, the ammonia gas sensor 1000 detects the ammonia gas leaked from the glass valve 600 and outputs the ammonia gas to the controller 1100. 1100 receives the detection signal from the ammonia gas sensor 1000 to operate the motor 820 and the solenoid valve 300.

As the gear unit 810 rotates due to the rotation of the motor 820, the outer body 720 engaged with the gear unit 810 and the teeth 721b rotates, and due to the rotation of the outer body 720. The first extinguishing exhaust portion 712a of the inner body 710 that is blocked by the outer 720 is opened while naturally communicating with the second extinguishing exhaust portion 722a of the outer body 720.

In addition, the fire water is injected through the injection unit 111 while the fire water transfer line 110 is opened due to the operation of the solenoid valve 300.

On the other hand, the second coupling hole (721a) and the first coupling hole (711a) is in communication with each other at any moment in the process of rotating the outer body 720 of the blower pipe 700 by the switch 800, as described above When the two coupling holes 711a and 721a communicate with each other, the striking pin 1220 is inserted into the first and second coupling holes 711a and 721a by the springing force of the spring 1230 to rotate the outer body 720. At the same time, the blow pin 1220 blows strongly against the glass valve 600 blocking the hole of the nozzle 410 to blow the glass valve 600 at a time, the extinguishing agent filled in the tank 400 nozzle 410 is ejected through.

And the extinguishing agent ejected through the nozzle 410 is discharged to the lower side of the ejection pipe 700, the injection is made to the surroundings through the first and second extinguishing exhaust parts (712a, 722a) in the process of being discharged downward.

As such, the present invention has the advantage of significantly improving the reliability of the product because it is possible to implement a smooth operation in any situation, whether the fire or fire.

Although the present invention has been described in detail only with respect to the specific embodiments described, it will be obvious to those skilled in the art that various modifications and changes can be made within the technical scope of the present invention, and such modifications and modifications belong to the appended claims.
