Abstract

The invention discloses an automatic counterglow orientator of a satellite solar array. The automatic counterglow orientator of the satellite solar array comprises a light-shading cantilever beam and the like, wherein an upright column is mounted on a solar array frame; the solar array is rotatably fixed at the lower end of the solar array frame; the light-shading cantilever beam is fixed at the top end of the upright column; three hinges are hinged to each of a first cylindrical hinge shaft, a second cylindrical hinge shaft, a third cylindrical hinge shaft and a fourth cylindrical hinge shaft; the first cylindrical hinge shaft and the second cylindrical hinge shaft are respectively fixed at two ends of the light-shading cantilever beam; and the third cylindrical hinge shaft and the fourth cylindrical hinge shaft are fixed on the solar array. A receiving angel of the satellite solar array to solar energy can be adjusted. The automatic counterglow orientator of the satellite solar array is stable and reliable in structure and high in adjustment degree of freedom.

Description

technical field [0001] The invention relates to a directional device, in particular to an automatic sun-aligning directional device for satellite solar panels. Background technique [0002] With the development of large military satellites, weather satellites and commercial broadcast communication satellites, satellites have higher and higher energy requirements. At present, the main energy source of the satellite system is solar energy. In order to make full use of the electric energy generated by solar panels, large satellites usually have a driving device, whose main mission is to drive the battery array to rotate and make its normal line coincide with the sunlight beam, so as to avoid the solar panels from being damaged by changes in the incident angle of sunlight. The decline in power generation makes the power generation of solar panels stable. [0003] At present, single-degree-of-freedom-driven solar panels are widely used and the technology is mature. For a space...
