[0002] The collector is the core equipment that converts solar radiation energy into thermal energy. The main principle is to use the reflector on the collector to reflect sunlight to the surface of the collector tube located at the focal line of the reflector. In order to ensure that the reflector can stably reflect sunlight to the collector tube, the back of the reflector is generally fixed by a cantilever beam, and the cantilever beam is supported by a support frame.
