Technical Field

[0001] The invention relates to the technical field of protection of a camera for monitoring longitudinal tearing of a belt conveyor, and in particular to a protection device for a camera for monitoring longitudinal tearing of a belt conveyor based on CCD technology. Background Art

[0002] With the improvement of industrial automation, conveyor belts are widely used in many fields such as mining, manufacturing and logistics. The health of conveyor belts plays a vital role in the safety and efficiency of production lines. In particular, during the operation of conveyor belts, longitudinal tearing may occur due to material wear, mechanical failure or external factors such as sharp objects. Once tearing occurs, it may cause significant production interruption and economic losses.

[0003] Traditional conveyor belt detection methods mainly rely on regular manual inspections or basic mechanical monitoring. These methods are not only time-consuming, but also difficult to achieve real-time monitoring and precise positioning of the tearing location. In recent years, camera systems based on CCD technology have been used for longitudinal tear monitoring of conveyor belts, which can provide continuous, high-resolution image capture, thereby achieving real-time and accurate tear detection.

[0004] However, these monitoring cameras face environmental challenges in actual applications, such as dust, water vapor, chemical corrosive substances and vibration during the operation of the belt conveyor. These factors may not only damage the external lens of the camera, but also affect the electronic components inside the camera, thereby reducing the accuracy and life of the monitoring system. For this reason, we propose a protection device for the longitudinal tear monitoring camera of the belt conveyor based on CCD technology. Summary of the invention
