Abstract

The invention discloses a heliostat bracket which comprises 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 in the extension direction of the central axis of the main beam, wherein each bracket unit comprises a central bracket fixedly arranged on the main beam in a sleeving manner and an auxiliary beam connected with the main beam through the central bracket; each central bracket comprises a first supporting piece and a second supporting piece which are arranged in parallel at intervals, wherein the first supporting piece and the second supporting piece are fixedly connected through at least one supporting piece located between the first supporting piece and the second supporting piece; and each central bracket is arranged on the main beam in a sleeving manner through a first through hole formed in the corresponding first supporting piece and a second through hole formed in the corresponding second supporting piece and fixedly connected with the main beam. According to the heliostat bracket, the central brackets for connecting the main beam and the auxiliary beams are arranged, so that the heliostat bracket has relatively high reliability and durability, and can still keep a good surface shape after being used for a long time.

Description

technical field [0001] The invention belongs to the technical field of small-scale solar thermal power generation, and in particular relates to a heliostat frame, a heliostat and a heliostat field. Background technique [0002] As a clean and renewable energy, solar energy has been applied more and more. Solar thermal power generation technology is a new solar energy utilization technology after photovoltaic power generation technology. Among them, tower-type 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 the tower solar thermal power generation is to gather sunlight to the heat absorber, heat the heat absorbing or heat storage working fluid in the heat absorber, generate high temperature and high pressure steam, and then drive the steam turbine to generate electricity. The performance of the heliostat frame determines the quality of the heliost...
