Low Latitude Dish Stirling Solar Power Plant

Abstract

The invention discloses a low-latitude dish Stirling solar power generation device. The low-latitude dish Stirling solar power generation device comprises a vertical column (1), a dish condenser and a Stirling engine. A dish surface supporting flange (2) of the dish condenser is in a big-end-down trumpet shape, and one end of the dish surface supporting flange (2) is open to form a U-shaped groove. The vertical column (1) penetrates through the U-shaped groove. A rotating flange (7) is installed at the top of the vertical column (1). A Stirling arm (4) is hinged and installed on the rotating flange (7). A lead screw supporting arm (3) is installed at the upper end of the rotating flange (7). The Stirling arm (4) and the lead screw supporting arm (3) are connected through a lead screw transmission mechanism (6). The lead screw transmission mechanism (6) is driven by a servo motor (5). According to the low-latitude dish Stirling solar power generation device, an existing dish surface driving device is improved, the mechanical structure design is modified, the dish surface supporting flange is changed from the shape that the upper surface and the lower surface are the same to the big-end-down trumpet shape, and thus dish surface perpendicular angle operation can maximally reach 100 degrees.

Description

technical field [0001] The invention relates to a Stirling solar power generation system, in particular to an installation structure of a dish-type Stirling power generation device. Background technique [0002] The dish-type Stirling solar power generation system requires the cooperation of horizontal drive and vertical drive to turn the dish to the angle facing the sun. The horizontal drive controls the azimuth angle of the dish to move within the range of 0~360°, and the vertical drive controls the movement of the elevation angle of the dish surface within the range of -20~90°. [0003] During the power generation process of the power generation system, all the mirrors are facing the sun, reflecting the sunlight and focusing it on the thermal head of the engine. If the engine fails to absorb the heat in time and convert it into electrical energy, the temperature at the thermal head will reach more than 1,000 degrees , will burn out the engine. In order to ensure the saf...

Problems solved by technology

At present, the most representative one is the dish-type Stirling solar power generation system of SES Company of the United States, which can reach 90° in the vertical direction. to 90° on request

In low-latitude regions, the altitude angle of the sun can often reach 90°, and the existing dish system cannot control the deviation of the light spot in case of an emergency.
