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.
本发明涉及卫星展开机构技术领域,具体为一种太阳翼多方位包围式固定装置,其包括:安装在太阳毯两端并处于压紧释放装置中心位置的火工分离螺母,所述火工分离螺母周围均匀分布有四块大小相同的支撑板,所述每块支撑板间通过定位件进行相互抵合定位,所述每个定位件上固定有压紧机构,所述压紧机构内部安装有压紧弹簧,所述压紧弹簧间穿有压紧杆,所述压紧杆穿过定位件并与火工分离螺母相固定,支撑板上端与上太阳箱板通过固定件固定安装,下方所述支撑板下端与下太阳箱板通过固定件固定安装,本发明通过向中心进行夹紧,向四角进行同时释放,可以在使每块支撑板稳定释放的前提下保证太阳翼展开的稳定性。
