Problems solved by technology
However, in the prior art, after the heliostats in the mirror field are arranged according to the theoretical coordinates, due to the deviation of the field flatness precision of the mirror field and the deviation of the installation height of each heliostat column, the actual height of each heliostat reflector is different from the theoretical height. There is a large deviation in the height, so that the light blocking amount between the mirrors of each heliostat cannot be effectively reduced, which affects the improvement of the efficiency of the entire mirror field

The invention relates to a heliostat device. The device comprises reflectors, reflector supporting carriers, a connection base, an altitude angle driver, an azimuth angle driver and a column. The reflectors are fixedly arranged on the reflector supporting carriers, the reflector supporting carriers are hinged to the connection base, and the altitude angle driver drives the reflector supporting carriers to follow the sun around the connection base in the altitude angle direction; the connection base is fixedly arranged on the azimuth angle driver and indirectly drives the reflector supporting carriers to follow the sun in the azimuth angle direction; the azimuth angle driver is hinged to the column, through cooperation a first mechanism on the azimuth angle driver and cooperation of a second mechanism on the column, the heights of the reflectors are adjusted, the heights of all the reflectors in a mirror field trend to the theory height designed by the mirror field, and it is guaranteedthat the light ray shielding quantity of all the reflectors trends to be least, so that the efficiency of the mirror field is improved.
Description
Technical field [0001] The invention belongs to the field of solar thermal power generation, and particularly relates to a heliostat reflector height adjustment device and a heliostat device. Background technique [0002] As a kind of clean renewable energy, solar energy has been applied more and more. In particular, solar thermal power generation technology is an emerging solar energy utilization technology after photovoltaic power generation technology. Among them, tower solar thermal power generation technology has energy storage and peak shaving. The benefits have received widespread attention. [0003] The function of the heliostat in the tower solar thermal power generation is to concentrate sunlight on the heat absorber, generate high temperature and high pressure steam by heating the working fluid, and then drive the steam turbine to generate electricity. The heliostat is a concentrating device composed of a mirror, a mirror frame, a tracking device and its control system,...
