Description

Technical Field

[0001] The utility model relates to an automatic cleaning device applied to a solar panel, belonging to the technical field of solar panel cleaning. Background Art

[0002] At present, small rooftop photovoltaic equipment can not only greatly reduce the expenditure of household electricity bills in daily life, but also alleviate the pressure of electricity consumption in cities during peak hours of urban electricity consumption, while also ensuring household electricity consumption. However, in most areas, dust accumulation on the surface of rooftop photovoltaic components is a difficult problem to solve, which greatly affects the power generation efficiency of solar panels. In most areas, cleaning once a week is basically the minimum frequency to ensure power generation efficiency. The power generation efficiency is difficult to guarantee due to the great influence of wind and dust. The fully automatic photovoltaic cleaning devices on the market are mostly large-scale equipment for cleaning photovoltaic power plants. It is difficult to play a role in small power generation places such as roofs. Most small photovoltaic panel cleaning equipment is semi-automatic equipment or some household cleaning appliances that require time-consuming and laborious manual operation. For example, the Chinese invention patent with publication number CN108080298A discloses a solar panel cleaning device, including a solar panel, a protective plate, and a frame for fixing the solar panel and the protective plate. The two sides of the frame protrude from the protective plate, and the frame part protruding from the protective plate is relatively provided with a track groove, and a cleaning piece is movably arranged in the track groove, and the two ends of the cleaning piece are respectively located in one of the track grooves. This solution cannot ensure close contact between the cleaning parts and the surface of the solar panel. If the gap is too large, it may lead to the inability to effectively clean the dust on the surface of the solar panel, affecting the power generation efficiency of the solar panel.
