Repeatedly-unfolded-folded solar wing device suitable for lunar surface environment

Abstract

The invention discloses a repeatedly-unfolded-folded solar wing device suitable for the lunar surface environment. The repeatedly-unfolded-folded solar wing device comprises a perambulating device structure, a +Y wing solar panel, a -Y wing solar panel, a pressing and releasing mechanism and a comprehensive electronic mechanism, wherein the back face of the +Y wing solar panel is wrapped by a plurality of layers of heat insulation assemblies, the +Y wing solar panel is connected to the perambulating device structure through a +Y wing driving mechanism and a +Y wing compensation mechanism, the -Y wing solar panel is connected to the perambulating device structure through an unfolded locking mechanism, the pressing and releasing mechanism is used for respectively pressing the +Y wing solar panel and the -Y wing solar panel on the perambulating device structure when folding launching is carried out, and the comprehensive electronic mechanism can unlock the -Y wing solar panel through a detonation pressing and releasing mechanism and control the +Y wing driving mechanism to drive the +Y wing solar panel to be opened to be capable of respectively achieving the sun orientation angle, the sun shielding angle and the moon night heat preservation angle. According to the repeatedly-unfolded-folded solar wing device, repeatedly-unfolding-folding operation can be achieved, multiple tasks such as sun orientation, sun shielding and moon night heat preservation in the lunar surface environment can be achieved, and the repeatedly-unfolded-folded solar wing device is flexible in use and powerful in function.

Description

technical field [0001] The invention discloses a multi-fold deployment and retraction solar wing device suitable for the lunar surface environment, which can realize multi-task requirements. Background technique [0002] At present, most of the known solar wing deployments of domestic spacecraft adopt the same deployment direction and one-time continuous deployment scheme. For example, the existing models FY-3, DFH-3, etc. rely on the power of the driving spring in the hinge to unfold the battery panel to the specified position at one time, and then rely on the locking device in the hinge to fix the battery panel in the specified position. This form of solar wing is good in terms of the maturity of the design technology and the application of the model, but for the solar wing that needs to be deployed, folded, and multi-functional in special working modes, its shortcomings are mainly manifested in the following aspects: exist: [0003] a. The function of the solar wing is ...
