[0002] Thermal energy storage technology uses heat storage materials as a medium to convert solar thermal, geothermal, industrial waste heat, low-grade waste heat, or electrical energy into thermal energy and store it, and release it when needed to solve the problems caused by the mismatch between thermal energy supply and demand in time, space or intensity, and maximize the energy utilization rate of the entire system; solar thermal arrays use large-scale arrays of parabolic or dish-shaped mirrors to collect solar thermal energy, provide steam through heat exchange devices, and combine with traditional steam turbine generator technology to achieve the purpose of power generation.

[0003] The existing solar thermal array is mainly composed of a mounting support, a control system, and a reflective mirror, commonly known as a heliostat. It needs to be installed in places with good direct solar radiation and low rainfall. Deserts and Gobi areas are the best choices. However, these areas have strong winds all year round, with flying sand and dust, which causes the surface of the heliostat to be covered with sand and dust, affecting the focusing and heat collection effects. Relying on traditional water trucks for manual spraying is too wasteful of water for water-scarce arid areas, and the labor cost is also high. Utility Model Content
