[0025] During work, the baffle 21 is provided with the built-in infrared sensor 22 in the device hole formed in the surface of the baffle 21, so that the detection direction of the baffle 21 is accurately aligned with the groove axis of the pulley 1, and the baffle 21 is used for continuously monitoring the vertical deviation of the belt during operation; the device box 23 is fixed to the bottom surface of the baffle 21 and transmits the distance signal collected by the infrared sensor 22 to the control board 24 in the device box 23 through wires; the control board 24 analyzes the signal fluctuation characteristics based on a preset algorithm, and when the fluctuation amplitude exceeds a threshold value, triggers the wireless module to send a belt loosening alarm information to an external terminal, thereby realizing a real-time early warning function.

[0026] Further, the protection assembly 3 comprises a connecting rod 31 fixedly connected to the bottom surface of the baffle 21, a hydraulic buffer rod 32 fixedly connected to the bottom end of the connecting rod 31, a bracket 33 fixedly connected to the bottom end of the hydraulic buffer rod 32, a spring 34 sleeved on the surface of the hydraulic buffer rod 32, side plates 35 fixedly connected to both ends of the bracket 33, rotating blocks 36 fixedly connected to both sides of the connecting rod 31, and telescopic rods 37 fixedly connected to the side surfaces of the rotating blocks 36.

[0027] During work, when the connecting rod 31 at the bottom of the baffle 21 is pressed down by vibration, the hydraulic buffer rod 32 and the spring 34 coaxially sleeved with the hydraulic buffer rod 32 are synchronously compressed, the vibration energy is absorbed by the flow of the hydraulic medium and the elastic deformation, the side plates 35 fixedly connected to both ends of the bracket 33 and the rotating blocks 36 on both sides of the connecting rod 31 are linked and supported through the telescopic rods 37, the displacement of the connecting rod 31 is limited in the horizontal direction, and the rotating blocks 36 rotate with the vibration to adjust the stretching angle of the telescopic rods 37, so that the stable attachment of the baffle 21 and the pulley 1 is maintained through multi-directional dynamic buffering, and the loosening of the structure is prevented.
