[0002] Solar energy is the most eye-catching clean energy among new and renewable energy sources. It is green and low-carbon, and is conducive to energy conservation and environmental protection. Therefore, solar energy utilization technology has received more and more attention. Solar water heaters absorb solar radiation energy through collectors, and then convert solar radiation energy into heat energy for heating water. Collectors are also called collector plates. In order to better absorb solar radiation energy, the collector plates are usually laid flat in an open high place to absorb solar radiation energy. After a period of use, the surface of the collector plates is often covered with dust, which affects the absorption of solar radiation energy.

[0003] In order to meet the solar water heater's absorption efficiency of solar radiation energy, workers are usually required to regularly clean the surface of the collector plate. However, the collector plate of the solar water heater is usually laid flat on the roof, and it is very dangerous for workers to climb up to the roof for cleaning, and the cleaning efficiency is low.

[0004] Therefore, there is an urgent need for a green and low-carbon solar water heating device that can automatically clean the surface of the collector plate. Summary of the invention
