Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0031] When a heat source appears inside the fire channel body 1, the heat source is fire, and the temperature inside the fire channel body 1 will continue to rise. When the temperature inside the fire channel body 1 reaches the set value of the temperature sensor 21, the temperature sensor 21 transmits the detected information to the controller, and the solenoid valve 10 is controlled by the controller so that the nitrogen in the self-pressurized liquid nitrogen tank 8 can be sprayed into the connecting pipe 9. The nitrogen in the connecting pipe 9 is sprayed out through the delivery pipe 11 and multiple nozzles 12 at one time, so that the nitrogen can extinguish the heat source in the fire channel body 1.

[0032] Embodiment 2

[0033] Although the above-mentioned embodiment 1 can extinguish the heat source (fire) in the fire channel body 1, it takes a certain amount of time to extinguish the heat source in the fire channel body 1, which causes the fire source to spread in the fire channel body 1, thereby bringing certain safety hazards. Therefore, in order to solve the above-mentioned technical problems, improvements are made on the basis of embodiment 1:

[0034] A placing plate 13 is fixed on one side of the lower part of the fire channel body 1, and two mutually parallel side plates 14 are fixed on the top of the placing plate 13. The output shafts at both ends of the take-up drum 3 are rotatably mounted on the side plates 14 respectively, and the rotating shaft at one end of the take-up drum 3 passes through the side plate 14 and is equipped with a locking assembly 15. The placing plate 13 is also equipped with a driving structure used in conjunction with the locking assembly 15. Through the setting of the driving mechanism, the take-up drum 3 can be rotated in an electric manner. The output shaft at the other end of the take-up drum 3 passes through the side plate 14 and is fixed with a rotating disk 16, and the outer surface of the rotating disk 16 is provided with an anti-slip coating. Through the setting of the rotating disk 16, the take-up drum 3 can be rotated manually; a traction rope 5 is wound around the take-up drum 3, and the traction rope 5 is made of a steel wire rope, which has good firmness and is not easy to break;

[0035] A frame 2 of an inverted "U"-shaped structure is fixed to the top of the fire channel body 1, and the frame 2 is located on one side of the self-pressurized liquid nitrogen tank 8. A sliding wheel 17 is fixed to the upper part of one side of the frame 2 and the center of the inner top wall, and one end of the traction rope 5 passes through the sliding wheel 17 on the upper part of one side of the frame 2, extends to the inside of the frame 2 and passes through the sliding wheel 17 on the inner top wall of the frame 2 and is fixedly connected to the gate plate 6. Through the setting of the sliding wheel 17, the traction rope 5 can pull the gate plate 6 up and down more smoothly. The lower plate of the frame 2 is symmetrically fixed with support plates 18, and the gate plate 6 is located between the two support plates 18. Through the setting of the support plates 18, on the one hand, the firmness of the frame 2 can be strengthened and the shaking of the frame 2 can be reduced. On the other hand, the gate plate 6 can be limited by two support plates 18 to prevent the gate plate 6 from rotating on the frame 2; a through slot is provided on the top of the fire channel body 1, and the through slot is located directly below the gate plate 6, so that the gate plate 6 can extend downward to the inside of the fire channel body 1 through the through slot, and a limiting plate 19 is fixed inside the fire channel body 1, and the limiting plate 19 is located directly below the gate plate 6, and a through hole is provided on the limiting plate 19, and a limiting slot 20 connected with the through slot is also provided on the limiting plate 19. Through the setting of the limiting plate 19, when the gate plate 6 falls into the inside of the fire channel body 1, it can play a limiting role to prevent the gate plate 6 from shaking in the fire channel body 1;

[0036] Specifically, the driving mechanism includes a motor 41 mounted on the placement plate 13, the temperature sensor 21 on the top wall of the fire channel body 1 is electrically connected to the controller outside the fire channel body 1 through a wire, and the controller is connected to the motor 41 through a wire, thereby controlling the motor 41, and the output shaft of the motor 41 is installed with a worm gear reducer 42, and the worm gear reducer 42 is set to reduce speed, and a locking hole 43 is opened on the output shaft of the worm gear reducer 42;

[0037] Specifically, the locking assembly 15 includes a rotating sleeve 151 fixed on the rotating shaft at one end of the take-up reel 3, and the inner wall of the rotating sleeve 151 fits with the output shaft of the worm gear reducer 42. The rotating sleeve 151 is provided with mounting holes 152 symmetrically about the axis. One end of the latch 153 passes through one of the mounting holes 152 on the rotating sleeve 151, the locking hole 43 and another mounting hole 152 on the rotating sleeve 151 in sequence, and a nut 154 is threadedly connected thereto, thereby locking the take-up reel 3 and being able to drive the take-up reel 3 to rotate electrically.

[0038] When a heat source appears inside the fire channel body 1, it should be noted that: the heat source is a fire source, and the temperature inside the fire channel body 1 will continue to rise and reach the set value of the temperature sensor 21. The temperature sensor 21 transmits the detected information to the controller, and the motor 41 is turned on by the controller. The output shaft of the motor 41 extends to the worm gear reducer 42. The rotation speed can be reduced by the worm gear reducer 42 and the locking assembly 15 is used to drive the take-up drum 3 to rotate. The take-up drum 3 can realize the function of releasing the wire during rotation. The gate plate 6 pulls the traction rope 5 downward under its own gravity, so that the traction rope 5 passes through the through groove and extends into the limit plate 19 and blocks the through hole, which can realize the function of blocking the heat source in the fire channel body 1 and prevent the heat source in the fire channel body 1 from spreading, thereby reducing safety hazards.

[0039] If the take-up drum 3 is rotated manually, first remove the nut 154 from the end of the pin 153, and then pull the pin 153 to remove the pin 153 from the inside of the rotating sleeve 151, and then rotate the rotating disk 16 to make the rotating disk 16 drive the take-up drum 3 to rotate, thereby realizing the function of releasing the line, and the gate plate 6 moves downward under its own gravity and pulls the traction rope 5, so that the gate plate 6 can extend through the through groove to the limit plate 19 to block the through hole, thereby achieving the effect of blocking the heat source in the fire channel body 1 and preventing the heat source in the fire channel body 1 from spreading.
