(1) Technical field

The utility model belongs to the technical field of automatic cleaning, in particular to an automatic cleaning device for solar battery panels.

(2) Background technology

Facing the challenges brought by global climate change and energy security issues, human beings need to seek renewable energy, and solar energy is a clean and renewable energy. With the reduction of the cost of solar power generation, the photovoltaic industry has entered a new era of global development. The solar panel is the source of electricity generated by the solar power station, and the efficiency of photovoltaic modules to convert solar energy directly determines the power generation of the solar power station. my country's ground-mounted photovoltaic power stations are mainly concentrated in the northwest region. These regions are rich in solar energy resources and have more than 3200 hours of sunshine throughout the year. However, the natural environment in the northwest region is relatively harsh, especially in the spring and autumn. Sandstorms will bring a lot of dust to the surface of photovoltaic modules Dust seriously affects the power generation efficiency of photovoltaic modules. Generally, for solar cell modules that have not been cleaned for 3 months, there will be a 5% output power loss. If the day is not cleared, the loss will reach about 12%.

At present, for the dust removal of photovoltaic power plants, cleaning methods such as manual, high-pressure water guns, and spray systems are adopted. The cleaning efficiency of manual cleaning is low, and the difference in personnel quality makes the cleaning process difficult to control, the cleaning effect is poor in consistency, and the glass of the component is worn, which affects the light transmittance and life: the high-pressure water gun cleans with a large amount of water, and the water consumption of 1MW per cleaning is about 1 0 Tons, not suitable for water-deficient areas, some water guns have high pressure, which will cause cracks in components, and mountain power stations that are not suitable for vehicles cannot be used; the cleaning effect of the spray system is not good, and the water consumption is large, and the water consumption of 1MW per cleaning About 6-7 tons.

The existing disclosed devices for automatically cleaning solar panels, especially large-scale solar panel cleaning devices, need to modify the solar panel group because the cleaning machine is too large and heavy, and an external support is required. The installation requirements of the solar panels are relatively high, and they need to be closely installed in the same horizontal plane, and the solar panels cannot be cleaned when the gap is large or tilted; the solar panels installed in different areas cannot be cleaned by themselves, which will cause the cleaning brush to be too dirty and affect The cleaning effect of the cleaning device. At the same time, due to the weight of the up and down circulation cleaning device, when running upward, it needs to overcome its own weight, which consumes a lot of power; when running downward, it needs to limit the running speed and consume energy, which affects the operation stability of the cleaning device.
