[0019] By clamping one group of clamp assemblies 3 on the connecting plate 2 of the fire damper body 1, and then lifting the pressure plate 8 upward to drive the turntable 7 to rotate, the turntable 7 can be rotated on the connecting frame 4. With the cooperation of the connecting rod 5, the two sides of the connecting frame 4 can be opened, so that the gear ring 2 12 is disengaged from the gear ring 2 12, and then the connecting arm 13 is rotated to enable the connecting sleeve 9 to rotate on the connecting rod 5, so that the angle of the other clamp assembly 3 can be adjusted, thereby realizing that the other group of clamp assemblies 3 can be clamped on the bent pipe, which has good applicability. After the angle is adjusted, the pressure plate 8 is pressed downward to drive the turntable 7 to reset, so that the gear ring 2 12 can be clamped into the gear ring 1 10, and the connecting sleeve 9 is locked.
[0020] The upper surface of the fire damper body 1 is provided with a valve controller 14, and a temperature sensor 15 is provided inside the valve controller 14;
[0021] By arranging a temperature sensor 15 on the fire damper body 1, the ambient air temperature can be detected in real time.

One end of the second half-clamp 302 is fixedly connected with a fixed rod 303, and one end of the first half-clamp 301 is rotatably connected to the outer wall of the fixed rod 303.

[0024] When the device needs to be used, one set of the clamp assembly 3 is clamped on the connecting plate 2 of the fire damper body 1, and then the pressing plate 8 is lifted upward to drive the turntable 7 to rotate. Thus, the turntable 7 can rotate on the connecting frame 4. With the cooperation of the connecting rod 5, both sides of the connecting frame 4 can be opened, so that the second toothed ring 12 is disengaged from the first toothed ring 12. Then, the connecting arm 13 is toggled to rotate, so that the connecting sleeve 9 can rotate on the connecting rod 5, and the angle of the other clamp assembly 3 is adjusted. Thus, it is realized that the other set of the clamp assembly 3 can be clamped on the bent pipeline, and the applicability is good. After the angle is adjusted, the pressing plate 8 is pressed downward to drive the turntable 7 to reset, so that the second toothed ring 12 can be engaged into the first toothed ring 10 to lock the connecting sleeve 9. By arranging a temperature sensor 15 on the fire damper body 1, the surrounding air temperature can be detected in real time. When the preset value is reached, the signal is transmitted to the valve 14 controller, so that the blades 17 can be closed to prevent the occurrence and further spread of fire.
