[0022] Through the above structure, the smoke exhaust fire damper is installed through the installation frame 17, the smoke is exhausted by rotating the exhaust fan 4, the temperature sensor 18 monitors the smoke temperature, the two groups of moving blocks 1 7 are moved out of the through slot 6, the moving block 2 9 is moved out of the storage slot 8, the exhaust fan 4 is clamped by the moving block 1 7 and the moving block 2 9, and the inside of the frame 1 is partitioned by the cooperation of the fan blades of the exhaust fan 4, the moving block 1 7 and the moving block 2 9, which plays the role of smoke isolation and fire prevention. The specific structure is as follows:
[0023] Combined with Figure 1 As shown, a mounting groove 2 is provided on the top of the frame 1, a motor 3 for driving an exhaust fan 4 is provided at the bottom of the mounting groove 2, and a controller 19 is installed inside the mounting groove 2.
[0024] Through the above structure, all the electric devices in the smoke exhaust fire damper are pre-set and automatically controlled through the controller 19. When the smoke exhaust fire damper is in an open state, the controller 19 controls the motor 3 to be in a rotating state, and drives the exhaust fan 4 to rotate through the motor 3.
[0025] Combined with Figure 2 and attached Figure 3 As shown, the movable block 1 7, movable block 2 9 and the upper and lower side walls of the exhaust fan 4 are respectively in contact with the upper and lower side walls of the frame 1, the front and rear side walls of the movable block 1 7 are respectively in contact with the inner wall of the through groove 6, and the front and rear side walls of the movable block 2 9 are respectively in contact with the inner wall of the storage groove 8.
[0026] Through the above structure, the upper and lower sides and the front and rear sides of the movable block 1 7 and the movable block 2 9 are evenly in contact with the frame 1, and the movable block 1 7 and the movable block 2 9 are in close contact with the blade edges of the exhaust fan 4, which can reduce the outflow of smoke as much as possible and effectively prevent fire.
[0027] Combined with Figure 2 and attached Figure 3 As shown, multiple sets of rotating shafts 11 are rotatably installed between the front and rear side walls of the through slot 6, multiple sets of elliptical push blocks 12 are installed on the outer side of the rotating shaft 11, and a motor 10 for driving the rotating shaft 11 is installed on the outer wall of the rear side of the I-shaped partition 5;
[0028] Two groups of limit rods 14 are installed between the two opposite side walls of the frame 1, and the two groups of limit rods 14 are respectively located at the front and rear sides of the two groups. The limit rods 14 slide through two groups of moving blocks 1 7 and moving block 2 9. One group of limit rods 14 has threads 15 at both ends, and the limit rods 14 are connected to the moving block 2 9 with the threads 15. A motor 3 16 is installed on the outer wall of one side of the frame 1 and located inside the mounting frame 17. The shaft end of the motor 3 16 is connected to a group of limit rods 14 installed with threads 15, and the two groups of threads 15 are in opposite directions.
[0029] Through the above structure, the motor 2 10 drives the rotating shaft 11 to rotate, and the side of the long radius of the elliptical push block 12 is supported on the moving block 1 7, and the moving block 1 7 is pushed out of the through slot 6.

[0030] The moving block 1 7 and the moving block 2 9 are limited by two sets of limiting rods 14 so that the moving block 1 7 and the moving block 2 9 can slide smoothly. The motor 3 16 drives one set of limiting rods 14 to rotate, and drives the two sets of moving blocks 2 9 to move closer or farther away from each other through the threads 15 in opposite directions.
[0031] The specific usage is as follows:
[0032] When the temperature sensor 18 detects that the flue gas temperature reaches 280°C, the signal is transmitted to the controller 19. The controller 19 turns off the motor 3 to stop the exhaust fan 4 from rotating, and starts the motor 2 10 and the motor 3 16. The motor 2 10 drives the elliptical push block 12 to rotate, and pushes the moving block 1 7 out of the through slot 6 and makes close contact with the edge of the fan blade on one side of the exhaust fan 4. The motor 3 16 drives the limit rod 14 to rotate, and drives the two groups of moving blocks 2 9 to move closer through the thread 15 on the limit rod 14, so that the moving block 2 9 is in close contact with the edge of the fan blade on the other side of the exhaust fan 4, so that the moving block 1 7, the moving block 2 9 and the exhaust fan 4 separate the inside of the frame 1, thereby playing the role of isolating smoke and preventing fire.
