Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel cleaning equipment, in particular to a photovoltaic panel cleaning device. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert sunlight into electricity. It primarily consists of three main components: solar panels (modules), controllers, and inverters, with the majority of components being electronic components. Solar cells are connected in series and then packaged and protected to form large-area solar modules. Combined with components such as power controllers, these form photovoltaic power generation devices.

[0003] After long-term use, dust will adhere to the surface of photovoltaic panels, which will affect the absorption of sunlight. Therefore, the solar panels need to be cleaned regularly. For photovoltaic panels arranged at intervals, manual cleaning devices are usually used to clean the photovoltaic panels. The existing cleaning device mainly includes a cleaning component and a handrail component with a telescopic rod structure. The handrail component drives the cleaning component to move on the photovoltaic panel, so that the cleaning component cleans the photovoltaic panel. This cleaning device has the following disadvantages: 1. The cleaning component is pressed on the photovoltaic panel under the action of its own gravity, and the pressure of the cleaning component on the photovoltaic panel cannot be adjusted; 2. The handrail component adopts a manual length adjustment method, and the length needs to be adjusted before use. The length of the handrail cannot be freely adjusted during operation. Therefore, during the cleaning process, it is necessary to manually adjust the position of the cleaning component through the handrail, which wastes manpower and is inconvenient to use.
