[0030] The output end of the traction motor 4 is fixedly connected with a driving gear 41, which meshes with the rack 12. The traction motor 4 drives the driving gear 41 to rotate, and the driving gear 41 moves on the rack 12, so that the traction mounting bracket 3 moves as a whole. Limiting plates 42 are provided at both ends of the driving gear 41. The limiting plates 42 clamp both sides of the rack 12 to improve the tightness of the connection between the driving gear 41 and the rack 12 and prevent the driving gear 41 from being separated from the rack 12. During installation, the driving gear 41 is meshed with one end of the rack 12, and the photovoltaic panel body 2 is inserted between the clamping wheels 38 on the mounting bracket 3. The cleaning component can be disassembled, and one cleaning component can be used to clean multiple groups of photovoltaic panel bodies 2.

[0031] The central axis of the cleaning roller brush 5 is movably connected to the mounting bracket 3 through a bearing, a worm gear 51 is fixedly connected to the central axis of the cleaning roller brush 5, and a cleaning motor 52 is fixedly connected to the upper end of the central axis of the cleaning roller brush 5. The cleaning roller brush 5 is driven to rotate by the cleaning motor 52. When the cleaning roller brush 5 rotates, the worm gear 51 is synchronously driven to rotate, and the rotating cleaning roller brush 5 cleans the surface of the photovoltaic panel body 2.

[0032] A slider 61 matching the slide groove 33 is provided on one side of the upper and lower ends of the wiper strip 6, a half-wrapped thread groove 611 is provided on the slider 61, a worm 62 is sleeved in the half-wrapped thread groove 611, both sides of the worm 62 are movably connected with the slide groove 33 through bearings, the worm 62 is meshed with the worm wheel 51, and the worm wheel 51 drives the worm 62 to rotate, so the slider 61 meshed with the worm 62 moves along the direction of the slide groove 33. Specifically, the wiper strip 6 is arranged behind the working direction of the cleaning roller brush 5, and the cleaning roller brush 5 is brushed first. Wash, and then the excess water stains are scraped off by the wiper strip 6. Therefore, when the cleaning roller brush 5 has worked once and reached one end of the photovoltaic panel body 2, if it needs to be cleaned again, it is only necessary to control the traction motor 4 to move back. At this time, the wiper strip 6 is located in front of the working direction of the cleaning roller brush 5, and the cleaning motor 52 works in the reverse direction to drive the cleaning roller brush 5 to rotate. At this time, the worm 62 rotates in the reverse direction, and the slider 61 moves along the direction of the slide groove 33 to the other side of the cleaning roller brush 5, that is, keep the cleaning roller brush 5 working in front of the wiper strip 6.

[0033] In order to prevent the wiper strip 6 from moving further after moving to the end of the worm gear 62, a straight rod 621 is provided at the end of the worm gear 62, and no thread is provided on the straight rod 621. When the slider 61 is sleeved with the straight rod 621, the worm gear 62 rotates without controlling the movement of the slider 61. At the same time, a second spring 64 is sleeved on the straight rod 621. The second spring 64 is compressed when the slider 61 is sleeved with the straight rod 621, and the second spring 64 accumulates force. When the worm gear 62 rotates in the opposite direction, the second spring 64 pushes the slider 61 to engage with the worm gear 62, and under the control of the worm gear 62, the slider 61 drives the wiper strip 6 to move to the other side of the cleaning roller brush 5 until the slider 61 is sleeved with the straight rod 621 at the other end of the worm gear 62.

[0034] In order to enable the wiper strip 6 to move from both sides of the cleaning roller brush 5, a notch 63 is provided on the side of the wiper strip 6 close to the cleaning roller brush 5, and the notch 63 can pass through the outside of the cleaning roller brush 5. The side wall of the notch 63 is symmetrically provided with first inclined surfaces 631, and the two first inclined surfaces 631 form a sharp angle structure. When the sharp angle structure passes over the cleaning roller brush 5, the bristles can be moved to swing. When the wiper strip 6 moves to the position corresponding to the straight rod 621, the notch 63 of the wiper strip 6 is engaged with the water spray plate 32, and the water spray plate 32 is provided with a second inclined surface 321 matching the first inclined surface 631, and the second inclined surface 3 21 is in contact with the first inclined surface 631 to support the position of the notch 63 of the wiper strip 6. When the wiper strip 6 is working, it is located in front of the water spray plate 32 engaged with it, that is to say, the second inclined surface 321 is completely in contact with the first inclined surface 631, thereby improving the strength of the wiper strip 6. Water spray ports 322 are equidistantly arranged on one side of the water spray plate 32, and water is sprayed toward the photovoltaic panel body 2 by means of the water spray ports 322. It is worth noting that both water spray plates 32 are provided with water spray ports 322, but which specific water spray plate 32 is used depends on the moving direction of the cleaning component, and the water spray plate 32 located in front of the cleaning roller brush 5 sprays water.

[0035] The intelligent control module includes a cleaning control unit and an environmental detection unit. The cleaning control unit supports remote monitoring and operation. Users can interact through mobile devices or computers. The environmental detection unit is composed of a variety of sensors to obtain information such as temperature, humidity, wind speed, light intensity and air quality index. These data are crucial for judging the pollution of photovoltaic panels and are also the basis for optimizing cleaning strategies. The cleaning control unit automatically controls the work of the cleaning components according to the data provided by the environmental monitoring module, which is specifically reflected in:

[0036] Through sensors integrated in the environmental detection unit, such as optical sensors or dust sensors, the pollution on the surface of the photovoltaic panel is monitored in real time. When the pollution reaches the set threshold, the system automatically starts the cleaning program. This step mainly completes data collection through sensors;

[0037] The cleaning control unit connects to the weather service API to obtain weather forecast information for the next few days. If rainfall is predicted, the cleaning task can be postponed. On the contrary, cleaning is prioritized in clear weather to avoid interference caused by natural precipitation. This step obtains real-time and predicted weather data by calling the API provided by a third-party weather service provider.

[0038] By learning from past cleaning data, including pollution trends in different seasons and time periods, the cleaning control unit can predict future pollution patterns and formulate preventive maintenance plans in advance. This step uses supervised learning, unsupervised learning, or reinforcement learning methods to train models to identify pollution patterns, predict future trends, and optimize cleaning strategies. It uses collaborative filtering, content recommendation, and other algorithms to provide users with customized suggestions and services.

[0039] A specially designed mobile APP or web interface is provided, allowing users to view the operating status of the intelligent control module, cleaning progress and cleanliness of the photovoltaic panel anytime and anywhere. Users can also set cleaning parameters, initiate instant cleaning commands or view historical records through the application. Cross-platform development tools such as React Native and Flutter are used to quickly build an operation interface suitable for iOS and Android, and upload the operating status of the cleaning system to the cloud server. Users can access data through the Internet and execute remote control commands. The built-in health monitoring chip monitors key parameters such as motor current, temperature, vibration, etc. in real time, and warns of potential problems in advance. As a bridge connecting local devices and the cloud, it is responsible for data transmission and command forwarding to ensure the security and stability of communication.

[0040] Working process: During installation, the clamping wheel 38 makes the wheel body 382 closely contact the side wall of the photovoltaic panel body 2 through the action of the first spring 383, and the clamping wheel 38 is clamped with one end of the photovoltaic panel body 2. The driving gear 41 is meshed with the rack 12 on the supporting frame 11 to ensure that the cleaning component maintains a stable position during movement. The intelligent control module detects the environment and automatically controls the cleaning component to start the cleaning work. During operation, the cleaning motor 52 is turned on first, and the rotation direction of the cleaning motor 52 is adjusted according to the moving direction of the cleaning component. The worm gear 51 drives the worm 62 to rotate, and the wiper strip 6 moves to the rear of the forward direction of the cleaning roller brush 5 and presses against the water spray plate 32. At this time, the traction motor 4 is started, and the driving gear 41 rotates , moves along the rack 12, driving the entire cleaning assembly to move on the surface of the photovoltaic panel, the water spray plate 32 located in front of the cleaning roller brush 5 in the forward direction starts to spray water, and the cleaning roller brush 5 rotates forward to clean the photovoltaic panel body 2 after the water is sprayed, and the dirt on the bristles is scraped off by the scraper 311 and sucked into the dust suction pipe 34 through the dust suction ports on both sides of the scraper 311. The dust collector 35 collects the dirt and discharges it to the dust discharge pipe 36, and finally enters the collection box. After completing one cleaning, if the intelligent control module detects that it is not completely cleaned and needs to be cleaned, the cleaning motor 52 rotates in the reverse direction. After adjusting the position of the wiper strip 6, the traction motor 4 works in the reverse direction, driving the cleaning assembly to work in the reverse direction until the photovoltaic panel body 2 is completely cleaned.
