Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] figure 1, figure 2 , image 3 It is a structural schematic diagram of a step-by-step flexible solar cell array of the present invention. As shown in the figure, a step-by-step flexible solar cell array includes: an upper storage box 1, a lower storage box 2, a tensioning mechanism 3, a guiding mechanism 4, a pressing and releasing mechanism 5, and a plurality of flexible solar panels 6. The flexible solar panel array and the secondary unlocking device7. The flexible solar panel array is divided into a first-step expansion part and a second-step expansion part; the numbers of flexible solar panels 6 in the first-step expansion part and the second-step expansion part are respectively N1 and N2, and N1 and N2 are both Odd number; the secondary unlocking device 7 is located between the flexible solar panels 6 of N1 in the first step of expansion and N2...

Abstract

The invention relates to a flexible solar cell array unfolded step by step. The flexible solar cell array is composed of an upper storage box, a lower storage box, a tensioning mechanism, a guide mechanism, a pressing and releasing mechanism, a flexible solar cell panel, a secondary unlocking device and the like. The flexible solar cell array is used as a power generation device of a spacecraft, can bear a mechanical environment of a spacecraft launching section, has force energy for keeping two unfolding lengths and structural rigidity under the cooperation of an external unfolding mechanism,and meets a requirement of orbital transfer at an initial stage of orbital injection of a spacecraft, the requirement of a butt joint stage for a unfolding fundamental frequency of a solar cell arrayand the requirement of long-term on-orbit operation for generating power of the solar cell array at the same time.

Description

technical field [0001] The invention relates to the technical field of spacecraft solar cell arrays, and specifically provides a flexible solar cell array that can be deployed step by step. 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 the low fundamental frequen...
