Description

Technical Field

[0001] The utility model relates to the technical field of solar heat collection equipment, and particularly relates to a trough type heat collection device with a cleaning function. Background Art

[0002] With the growth of global energy demand and the improvement of environmental protection awareness, solar energy, as a clean and renewable energy form, has received extensive attention. Trough solar collectors have been widely used in the field of solar thermal utilization due to their high heat collection efficiency and relatively simple structural design. A trough collector usually consists of a concentrating mirror (such as a parabolic reflector) and a receiver placed at the focal point, which can focus sunlight onto the receiver to generate high-temperature heat energy for heating fluids or driving a thermal power generation system. However, in practical applications, a trough collector faces a major challenge, that is, the accumulation of dust and dirt on the concentrating mirror surface will significantly reduce its optical performance, thereby affecting the heat collection efficiency. Traditional cleaning methods mostly rely on manual cleaning, which is not only costly but also has problems such as incomplete cleaning and limited frequency. Content of the Utility Model
