Mirror automatic folding, positioning, splicing film condenser structure

Abstract

The structure of the spliced ​​thin-film condenser with automatic mirror folding and positioning, involves the field of space optics, and solves the problem that the gas-filled and hardened thin-film structure existing in the main mirror scheme of the 2007SSP integrated symmetrical condenser system proposed by NASA in the SERT research program is easy to be hit by particles in space. It is difficult to maintain the desired main mirror shape due to wear and tear, and it is easy to leak and have low reliability. The structure includes 90° hinges, electric control locks, 180° hinges, motors, turntable connection support bases, sliding guide rods, hinge rods, inner panels, outer panels, film mirror adjustment frames, film mirrors, upper plates, and truss rods , inner plate hinge support, lead screw limit sleeve, truss rod load-bearing base, moving lead screw, lead screw sliding nut, motor seat adjustment pad, motor seat, sliding guide ring, oil-free bushing, hinge rod shaft and limiters. The invention has the advantages of simple structure, easy processing and convenient assembly operation, avoids processing and manufacturing problems caused by complex combined structures, can greatly reduce processing and assembly costs of structural parts, shorten processing cycle, and has high reliability.

Description

technical field [0001] The invention relates to the technical field of space optics, in particular to a structure of a spliced ​​thin film condenser with automatic mirror surface folding and positioning. Background technique [0002] Thin film condenser is a light energy conversion device that uses the film reflective surface to reflect parallel light rays in space and converge and intersect at a certain position. This device can improve the efficiency of photoelectric conversion per unit area and reduce the reception of photoelectric conversion cells surface area. Thin-film concentrators are gradually applied to the light energy collection of space solar power plants because of their light weight and ability to withstand the influence of various harsh environments in space.
