Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] figure 1 , figure 2 , image 3 It is a secondary unlocking device used for step-by-step deployment of flexible solar cell arrays according to the invention. like figure 1 As shown, the secondary unlocking device includes an upper isolation plate 71 , a lower isolation plate 72 , a leaf hinge 73 , a spring cord assembly 74 , an adjustable limit block 75 for a reel, and a cable limit block 76 . Wherein the upper isolation plate 71 and the lower isolation plate 72 are connected by a sheet hinge 73, so as to realize the function of folding the upper isolation plate 71 and the lower isolation plate 72 to 180°. The external dimensions of the upper isolation plate 71 and the lower isolation plate 72 are consistent with those of the external flexible battery plate 77 . A total of four sets of spring rope assemblies 74 are installed in the pre-embedded in...

Abstract

The invention relates to a secondary unlocking device and method for step-by-step deployment of a flexible solar battery array. The secondary unlocking device is composed of an upper isolation plate, a lower isolation plate, a leaf hinge, a spring rope assembly and the like. The secondary unlocking device can realize the step-by-step deployment of the flexible solar cell array during the orbit change, docking stage and on-orbit operation of the spacecraft.

Description

technical field [0001] The invention relates to the technical field of spacecraft solar battery arrays, and is particularly suitable for realizing the step-by-step deployment function of flexible solar battery arrays. Background technique [0002] The flexible solar cell array has the characteristics of long deployment length and low fundamental frequency. It is very difficult to control the attitude of the spacecraft in its deployment state, especially the attitude control of orbit change and docking. Therefore, if the flexible solar cell array can only complete the first step of deployment before docking and docking of the spacecraft, the flexible solar cell array will have a shorter deployment length and a higher fundamental frequency to meet the spacecraft attitude control requirements. After the orbit change and docking, the second step of deployment is performed to fully meet the power generation requirements of the spacecraft, which can solve the contradiction between...
