[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

The invention relates to the technical field of satellite deployment mechanism, in particular to a solar wing multi-directional enveloping fixing device, which includes: pyrotechnic separation nuts installed at both ends of the sun blanket and at the center of the compression release device, the pyrotechnic separation nut Four support plates of the same size are evenly distributed around the nut, and each of the support plates is positioned against each other through a positioning piece. A pressing mechanism is fixed on each of the positioning pieces, and a pressing mechanism is installed inside the pressing mechanism. Compression springs, a compression rod is passed between the compression springs, the compression rod passes through the positioning part and is fixed with the pyrotechnic separation nut, the upper end of the support plate and the upper sun box board are fixed and installed by the fixing part, and the lower part The lower end of the supporting plate and the lower solar box plate are fixed and installed by the fixing parts. The present invention clamps to the center and simultaneously releases to the four corners, which can ensure the stability of the solar wing deployment under the premise of stably releasing each supporting plate.
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 ...
