Problems solved by technology

Once the focal spot produced by the concentrator needs to be removed from the daylight opening of the heat absorber, it will take a long time. Even if the speed of the concentrator driving device is increased, it is difficult to remove the focal spot from The light opening of the engine heat sink is completely removed to keep the engine in a safe state

Abstract

The invention discloses a protection device of a solar Stirling engine heat absorber. A Stirling engine comprises the heater absorber, the heater absorber is provided with a daylight opening, the protective device comprises a lightproof light screen, and the light screen is connected with an outer shell of the heat absorber in a rotating mode, so that the light screen rotates to a first position for shielding the daylight opening, or to a fourth position for opening the daylight opening completely, or to a second position and a third position which partially open the daylight opening. The protection device of the solar Stirling engine heat absorber can rapidly and effectively cut off the light path projected on the heat absorber to avoid overheating and overburning of the heat absorber.

Description

technical field [0001] The invention relates to the technical field of solar power output equipment, in particular to a heat absorber protection device for a solar Stirling engine. Background technique [0002] In the current production and life, the utilization of solar thermal power generation has more and more important social and economic significance. An important technical route for solar thermal power generation is the dish-type Stirling system, which uses a dish-type concentrator with a Stirling engine. This method has very flexible modular deployment capabilities and high light The heat conversion efficiency and the high utilization factor have received more and more attention and attention. [0003] In the dish-type Stirling solar thermal power generation system, the Stirling engine is the core component that completes the transformation of light energy into heat energy and further into mechanical energy, and the heat absorber is one of the key components of the s...
