PROTECTION APPARATUS FOR DISC-TYPE SOLAR THERMAL POWER GENERATION SYSTEM

摘要

A protection apparatus for a disc-type solar thermal power generation system comprises a driver (10), a transmission mechanism, a light shading assembly (3) and guide rails (9) in sequential connection. The light shading assembly (3) and the guide rails (9) are in matched connection in a manner of being capable of in reciprocating motion. The driver (10) provides a driving force by means of the transmission mechanism. The light shading assembly (3) moves along the guide rails (9) to a first position shading a light acquisition port (7) of the thermal power generation system or moves to a second position for opening the light acquisition port (7) under the action of the driving force. By using the structure, when the thermal power generation system normally works, the light shading assembly (3) moves to the second position, solar energy enters the light acquisition port (7) to perform power generation; when the thermal power generation system is in a failure and cannot normally output heat, the light shading assembly (3) moves to the first position, and solar energy projected on a high-temperature component of a heat absorber (6) is cut off to prevent the high-temperature component from being further heated and burnt, thereby providing a protection effect.
