Abstract

The invention discloses a linkage small-sized heliostat system. The linkage small-sized heliostat system consists of at least two small-sized heliostats (1) and an azimuth angle drive device (25); heliostat rollers (3) on the lower parts of heliostat upright posts (4) drive the heliostat upright posts (4) and heliostat reflecting surfaces (10) to rotate on heliostat bases (2); an azimuth angle drive roller (22) on the upper part of the azimuth angle drive device (25) is connected with the heliostat roller (3) adjacent to the azimuth angle drive roller (22) through a connecting element (14); adjacent heliostat rollers (3) are connected with each other through the connecting piece (14); the azimuth angle drive device (25) can drive a plurality of small-sized heliostats (1) to track the sun in the direction of a sun azimuth angle; and the upper parts of the heliostat upright posts (4) are provided with azimuth angle adjustment mechanisms (30) which are used for adjusting the heliostat reflecting surfaces (10) of the small-sized heliostats (1) at different positions, so that the sunlight reflected by the heliostat reflecting surfaces (10) aims at a target point in the direction of thesun azimuth angle.

Description

technical field

[0001] The invention relates to a linked small heliostat system in the field of solar thermal power generation. Background technique

[0002] At present, there are mainly three types of solar thermal power generation, which are tower solar thermal power generation, trough solar thermal power generation and dish solar thermal power generation. Among them, tower solar thermal power generation has a higher concentration ratio and higher power generation efficiency than trough solar thermal power generation. High advantage, and its power generation cost is lower than dish solar thermal power generation. The principle of the tower solar thermal power generation method is that multiple heliostats arranged in the heliostat field track the sun, reflect and focus the sunlight on the heat absorber on the high tower to generate high temperature and heat the working fluid Generate superheated steam to drive steam turbine generator set to generate electricity, thereby co...
