Solar wing multidirectional surrounding type fixing device

Abstract

The invention relates to the technical field of satellite unfolding mechanisms, in particular to a solar wing multi-directional surrounding type fixing device which comprises pyrotechnic separation nuts installed at the two ends of a solar blanket and located in the center of a pressing and releasing device, and four supporting plates with the same size are evenly distributed on the peripheries ofthe pyrotechnic separation nuts. The supporting plates abut against each other and are positioned through positioning pieces, a pressing mechanism is fixed to each positioning piece, pressing springsare installed in the pressing mechanisms, pressing rods penetrate through the pressing springs, the pressing rods penetrate through the positioning pieces and are fixed to the firer separating nuts,the upper ends of the supporting plates and the upper solar box plate are fixedly installed through fixing pieces, the lower ends of the lower supporting plates and the lower solar box plate are fixedly installed through fixing pieces, clamping is conducted towards the center, releasing is conducted towards the four corners at the same time, and the unfolding stability of the solar wing can be guaranteed on the premise that each supporting plate is stably released.

Description

technical field [0001] The invention relates to the technical field of a satellite deployment mechanism, in particular to a solar wing multi-directional surrounding fixing device. Background technique [0002] At present, the compression release device of the domestic solar wing deployment mechanism mostly adopts the compression rod type compression release form, which is similar to the screw tightening the fixed object. Control, and the compression force inside the compacted object is determined by the structural characteristics of the compacted object itself. When compressing the solar blanket of a large flexible solar wing, since the solar blanket is equipped with fragile solar cells, the compression release device of the pressing rod type cannot guarantee the compressive force inside the solar blanket, which is easy to cause Internal parts of the sun blanket are damaged. At the same time, it is also necessary to ensure a high level of compression between the outer box ...

Problems solved by technology

[0003] In the Chinese patent with the publication number CN105253331B, a force-limited compression release mechanism is provided. This mechanism adopts the form of two-stage loading, thereby realizing a relatively large compression force on the overall compression release mechanism, but this The compression force of the whole device is carried by only one compression rod between the upper and lower plates of the mechanism, which may cause the compression and release mechanism to be unable to separate stably due to the large vibration amplitude during launch, and this mechanism adopts a Z-shaped structure, resulting in horizontal use. waste of space
