Description

technical field

[0001] The invention relates to the technical field of solar concentrators, in particular to a detection device for focusing precision of a dish-type solar concentrator. Background technique

[0002] With the advancement of science and technology and the requirement of a comprehensive and coordinated sustainable development strategy, the use of solar thermal power generation technology has become more and more important. Dish-type Stirling solar thermal power generation belongs to the utilization of solar thermal power generation technology, which is a technology that gathers solar radiation energy to generate heat energy and generates power through thermal cycle.

[0003] At present, the dish-type Stirling thermal power generation system includes a Stirling generator. The Stirling generator is a photoelectric conversion component that absorbs the solar light energy collected by the dish-type solar concentrator through the thermal head and converts it into he...
