Problems solved by technology

Because the overall frame of the concentrator adopts the azimuth + elevation angle tracking method, no matter how the slave mirrors are arranged, the relationship between each slave mirror and the optical meridian plane is different and constantly changing, and the rotation mode of the independent rotating shaft is also very complicated

Embodiment Construction

[0012] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0013] The two-dimensional adjustment mechanism of the array reflector unit of the present invention comprises a reflector unit 2, an upper fork 4, a lower fork 5 and cross shafts 1, 3, wherein the longitudinal part 1 of the cross shaft is set in the hole of the lower fork 5, and the transverse part of the cross shaft 3 is set in the hole of the upper fork 4, and the mirror unit 2 is fixed on the upper fork 4;

[0014] In this way, the rotation of the longitudinal part 1 of the cross axis can drive the longitudinal rotation of the mirror unit 2 , and the rotation of the transverse part 3 of the cross axis can drive the lateral rotation of the mirror unit 2 , thus realizing the two-dimensional adjustment of the array mirror unit 2 .

[0015] In conclusion, the present invention provides a two-dimensional adjustment mechanism for mirror units, which can b...

Abstract

A reflecting mirror unit two-dimensional adjusting mechanism mainly comprises a reflecting mirror unit, an upper fork, a lower fork and a universal joint, wherein a longitudinal part of the universal joint is sleeved in a hole of the lower fork, a transverse part of the universal joint is sleeved in a hole of the upper fork, and the reflecting mirror unit is fixed on the upper fork. Accordingly, the reflecting mirror unit can be driven to rotate longitudinally through rotation of the longitudinal part of the universal joint and can be driven to rotate transversely through rotation of the transverse part of the universal joint. Therefore, array type reflecting mirror unit two-dimensional adjustment is achieved, and the reflecting mirror unit two-dimensional adjusting mechanism has the advantages of being stable in structure, and small in astigmation and off axis aberration.

Description

technical field [0001] The invention relates to the technical field of a tracking system and provides a tracking mechanism. Background technique [0002] The world's energy is depleting day by day, and the development and utilization of renewable energy have broad prospects. The comprehensive and efficient use of solar energy is the goal pursued by relevant people. Photovoltaic power generation devices use solar panels to receive sunlight and convert light energy into electrical energy, such as Difference is an important concept for judging and analyzing the pros and cons of focus. Roughly speaking, aberration is the difference between the actual spot and the ideal focused imaging spot. If the incident light is strictly parallel light, the ideal spot can be a geometric point. Considering the solar disk effect, the optimal spot is the radius equal to the focusing mirror The focal length multiplied by the beam opening angle of the circular spot. There may be many sources of ...
