[0002] At present, the photovoltaic panel is the core part of the solar power generation system, and its conversion efficiency directly determines the power generation of the solar power station; through the field measurement of photovoltaic power generation, the actual measurement results show that ash accumulation has a significant impact on photovoltaic power generation; the ash accumulation of photovoltaic panels has three Effect: The shading effect of photovoltaic panel dust accumulation, the temperature effect of photovoltaic panel dust accumulation, and the corrosion effect of photovoltaic panel dust accumulation. Therefore, the dust scale of photovoltaic panels has a great impact on the power generation efficiency and life of photovoltaic panels. Photovoltaic power generation is changing with each passing day. Photovoltaic panel cleaning has also become an urgent problem to be solved in the photovoltaic industry; the long-term accumulation of dust on the surface of photovoltaic panels has greatly reduced the power generation efficiency of photovoltaic panels; keeping photovoltaic panels clean can effectively maintain the maximum power generation capacity of photovoltaic power plants

[0003] In the prior art, the volume of the water storage tank is fixed, so the maximum value of water storage is fixed. When the water in the water tank is small, the water pressure will also decrease, causing inconvenience in using water; the collected rainwater often brings There are some impurities and other things that need to be filtered when using the collected rainwater. Most of the existing filters are used for filtering, and the filter needs to be cleaned, which brings inconvenience
