The invention discloses a frame structure of a Fresnel type solar reflector, which comprises a plurality of support plates, a longitudinal reinforcement structure and a longitudinal beam for installing the reflector. Beams, install longitudinal reinforcement structural members on the side and bottom of the support plate, and install rotating shafts on the outside of the support plates at both ends to support the bracket and realize the rotation of the bracket; cut grooves and gaps on the support plate, insert the longitudinal beam into the groove and install, The angle and height are limited by the grooves and gaps, so that the mounting surface of the reflector is parallel or tangent to the sticking surface of the reflector at the position, and the matching degree between the surface shape of the reflector and the designed surface shape is improved. The support plate in the frame and the longitudinal reinforcement structure are connected by bolts or riveting, which can be transported to the site in the form of components for quick assembly, which is convenient for reducing transportation costs.
Description
Technical field [0001] The invention belongs to the field of solar thermal power generation, and relates to a frame type linear Fresnel solar reflector frame. Background technique [0002] Solar thermal power generation technology uses a concentrator to gather solar energy and convert it into heat, and then generates high temperature and high pressure steam to drive a steam turbine to generate electricity. Linear Fresnel solar concentrating thermal power generation technology is a common form of solar thermal power generation. A mirror field composed of multi-faceted linear mirrors converges solar energy into linear light spots, and then uses a receiver to convert light energy into heat energy. The heat energy is absorbed and transferred to the heat exchanger through the heat transfer fluid. In the heat exchanger, the heat of the heat transfer fluid is used to heat water to generate steam, and then use the steam to drive a steam turbine to generate power. [0003] In the entire F...
