Description

Technical Field

[0001] This utility model relates to the field of cleaning mechanisms, and in particular to an automatic cleaning mechanism for photovoltaic panel surfaces. Background Technology

[0002] A photovoltaic (PV) panel is a device that directly converts sunlight into electrical energy. Its core component is the solar cell, which is mainly made of semiconductor materials. Cleaning mechanisms play an important role in the maintenance of PV power plants, effectively improving the power generation efficiency of PV power plants and extending the lifespan of PV modules.

[0003] Existing automatic cleaning mechanisms for photovoltaic panels have a relatively simple structure and limited cleaning range. They can only perform routine cleaning of dust and other contaminants. However, they are difficult to clean stubborn stains such as bird droppings and oil stains, resulting in poor cleaning effects, high maintenance costs, and corrosion and damage to the photovoltaic panels, causing them to age and affecting their lifespan.

[0004] Therefore, to address the problems of limited cleaning range, difficulty in removing stains, high maintenance costs, aging of photovoltaic panels, and reduced lifespan caused by existing automatic cleaning mechanisms for photovoltaic panels, an automatic cleaning mechanism for photovoltaic panel surfaces can be designed. This mechanism can be highly intelligent, using monitoring cameras for detection, and employing a comprehensive cleaning brush to ensure thorough cleaning without blind spots, thereby improving cleaning efficiency. It combines water spraying and brushing for precise cleaning, achieving a high degree of automation, reducing damage to photovoltaic panels, and improving their power generation efficiency.

The end of the inlet pipe away from the water pump is fixedly connected to the rear end of the water tank. The end of the outlet pipe away from the water pump is fixedly connected to the left side of the lower end of the diversion pipe. A protective top is fixedly connected to the front end of the mounting base.

[0014] The beneficial effects of this utility model are:

[0015] This automatic cleaning mechanism for photovoltaic panels utilizes a monitoring camera and cleaning brushes. The camera detects the contamination level of the photovoltaic panel and transmits the signal to the controller. With a high degree of intelligence, when ordinary dust or other contaminants are detected, the threaded rod rotates, causing the moving base to move up and down. The cleaning brushes move synchronously to sweep the dust off the surface of the photovoltaic panel, ensuring thorough cleaning without blind spots, improving cleaning efficiency and reducing maintenance costs. When stubborn stains such as bird droppings are detected, the threaded rod rotates, causing the moving base to move above the stubborn stains. Water is sprayed through a diversion pipe and nozzles to initially soften the stains, and the corresponding cleaning brushes rotate to remove them. This precise cleaning method, with its high degree of automation, combines water spraying and brushing for dual cleaning, ensuring the cleanliness of the photovoltaic panel surface, reducing damage to the panel, improving power generation efficiency, and extending its service life.

Simultaneously, the cleaning brush 10 moves to clean the dust on the surface of the photovoltaic panel body 4, ensuring thorough cleaning without blind spots, improving cleaning efficiency, and reducing maintenance costs. When stubborn stains such as bird droppings are detected, the threaded rod 6 rotates, causing the moving seat 7 to move above the stubborn stains.
