Therefore, it is rather troublesome to manually clean the lenses of the monitoring devices.

[0004] After searching, the patent with announcement number CN220254565U discloses a coal mine information safety monitoring device. When in use, water is sprayed onto the fixed brush through the nozzle. At the same time, the rear motor 2 drives the cleaning cloth wheel to rotate, and the cleaning cloth wheel is cleaned by the fixed brush. After cleaning, the extrusion plate is rotated to the position of the rear cleaning cloth wheel, and the extrusion plate squeezes the cleaning cloth wheel to discharge the water inside the cleaning cloth wheel. Then, the cleaning cloth wheel that has been cleaned is rotated to the right side of the camera, and the cleaning cloth wheel contacts the camera lens. Motor 2 drives the cleaning cloth wheel to rotate to clean the camera lens to ensure that the lens is clean, saving time and effort.
