Abstract

The invention discloses a mirror support structure for a heliostat, which comprises a main support, a unit sub-mirror and a heliostat transmission box, the main support is fixedly connected with the heliostat transmission box, and the unit sub-mirror Then it is arranged on the main support, and the upper part of the unit sub-mirror is fixedly provided with a glass reflector. The invention has the advantages of simple structure, light weight and low cost; the heliostat adjusted by adopting the structure has small reflection spot area and regular shape; and the adjustment process of the whole heliostat reflection surface is simple, convenient and has high precision.

Description

technical field [0001] The invention relates to the technical field of solar power generation, including solar thermal power generation and concentrated photovoltaic power generation, in particular to a light concentrating device applied to a tower type solar thermal power generation system and a tower type concentrated photovoltaic power generation system. Background technique [0002] In the past, power generation was mainly based on thermal power generated by burning coal. The consumption of a large amount of coal fuel has caused serious environmental pollution and the greenhouse effect, and coal is non-renewable. Humans have developed a variety of green power generation forms. Solar thermal power generation is One of the important forms of renewable energy, it can output power stably, and can act as a basic power source and a peak-shaving power source in the grid. Solar thermal power generation has many advantages such as clean and pollution-free in the whole process of ...
