[0016] After adopting the above scheme, the utility model has the following characteristics:

[0017] 1. When the belt cleaning device and the belt detection device of the utility model are in use, the scraper of the belt cleaning device contacts the outer surface of the belt of the belt conveyor to scrape off the materials attached to the belt of the belt conveyor, and the belt that has been scraped by the scraper then passes between the first light emitter and the first light receiver of the belt detection device. At this time, if the cleaning of the belt by the belt cleaning device does not reach the predetermined cleaning effect, the materials on the belt will block the first belt monitoring light emitted by the first light emitter, causing the first light receiver not to receive the first belt monitoring light. At this time, the first light receiver will emit a first belt warning signal to remind people that the cleaning effect of the belt cleaning device is unqualified; if the cleaning of the belt by the belt cleaning device reaches the predetermined cleaning effect, the first belt monitoring light emitted by the first light emitter will not be blocked by the materials, enabling the first light receiver to receive the first belt monitoring light. At this time, the first light receiver will not emit a first belt warning signal;

In addition, if an abnormal working condition occurs (such as the scraper is displaced), people can later obtain the condition of the scraper at the moment when the abnormal working condition occurs by reviewing the video, which is beneficial for people to analyze and solve the abnormal working condition. In addition, in the present utility model, a spray pipe is used to blow the camera to remove the dust on the camera, so as to prevent the camera from being blocked by dust and affecting the imaging effect of the camera.

[0021] 4. The drum cleaning device of the present utility model is used to clean the drum of the belt conveyor, so as to prevent the drum of the belt conveyor from remaining too much material and causing the belt of the belt conveyor to slip.

[0022] 5. When the drum cleaning device and the drum detection device of the present utility model are in use, the drum brush of the drum cleaning device contacts the outer surface of the drum of the belt conveyor to clean the material attached to the drum of the belt conveyor. Then, the drum after being cleaned by the drum brush passes between the second light emitter and the second light receiver of the drum detection device. At this time, if the cleaning of the drum by the drum cleaning device does not reach the predetermined cleaning effect, the material on the drum will block the first drum monitoring light emitted by the second light emitter, so that the second light receiver does not receive the first drum monitoring light. At this time, the second light receiver will emit a first drum warning signal to remind people that the cleaning effect of the drum cleaning device is unqualified. If the cleaning of the drum by the drum cleaning device reaches the predetermined cleaning effect, the first drum monitoring light emitted by the second light emitter will not be blocked by the material, and the second light receiver can receive the first drum monitoring light. At this time, the second light receiver will not emit the first drum warning signal.

[0023] 6. When the roller of the belt conveyor is running normally, the roller will block the second roller monitoring light emitted by the second light emitter, so that the second light receiver does not receive the second roller monitoring light. If the roller of the belt conveyor is displaced, the roller will be displaced so that the second roller monitoring light emitted by the second light emitter will not be blocked by the roller, so that the second light receiver receives the second roller monitoring light. At this time, the second light receiver emits a second roller alarm signal to remind people that the roller is displaced. BRIEF DESCRIPTION OF THE DRAWINGS
