Abstract

The invention discloses a heliostat frame, comprising a main beam and a plurality of bracket units arranged on the main beam at intervals, the plurality of bracket units are fixed on the main beam along the extension direction of the central axis of the main beam, wherein each bracket The unit includes a central support that is fixedly sleeved on the main beam, a sub-beam connected to the main beam through the central support, the central support includes a first support piece and a second support piece that are spaced apart and parallel to each other, the first support piece and The second support piece is fixedly connected by at least one support piece located therebetween; the central bracket is sleeved on the main support through the first through hole provided on the first support piece and the second through hole set on the second support piece on the beam and fixedly connected to the main beam. Through the arrangement of the central bracket connecting the main beam and the sub-beam, the invention enables the heliostat frame to have high reliability and durability, and can still maintain a good surface shape after long-term use.

Description

technical field [0001] The invention belongs to the technical field of small solar thermal power generation, and particularly relates to a heliostat frame, a heliostat and a heliostat field thereof. Background technique [0002] Solar energy has been used more and more as a clean and renewable energy. Solar thermal power generation technology is an emerging solar energy utilization technology after photovoltaic power generation technology. Among them, the tower solar thermal power generation technology has received extensive attention due to its advantages of energy storage and peak regulation. [0003] The function of the heliostat in tower solar thermal power generation is to gather sunlight on the heat absorber, and generate high-temperature and high-pressure steam by heating the heat-absorbing or heat-storing working medium in the heat absorber, which in turn drives the steam turbine to generate electricity. The performance of the heliostat frame determines the quality ...
