Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically a photovoltaic cleaning device. Background Technology

[0002] Photovoltaic panels are the core component of a solar power generation system. Being exposed to the outdoor environment for extended periods, their surfaces easily accumulate dust, bird droppings, fallen leaves, and other contaminants, affecting their solar energy absorption efficiency and consequently reducing power generation. To ensure the power generation efficiency of the photovoltaic system, the surface of the photovoltaic panels needs to be cleaned regularly.

[0003] Currently, traditional photovoltaic cleaning equipment mostly uses nozzles with fixed angles, which can only clean local areas of photovoltaic panels, easily creating blind spots. Furthermore, the equipment's movement path is limited, making it difficult to cover the entire panel. Some equipment also has a fixed spacing between its power frames, which can only accommodate cleaning tracks of a single width. When encountering tracks with photovoltaic panels of different sizes, the equipment needs to be replaced or additional adapters need to be installed, making it difficult to meet the flexible adaptation needs of cleaning diverse outdoor photovoltaic panels. In view of this, we propose a photovoltaic cleaning equipment. Utility Model Content
