The invention provides a separation and unlocking mechanism for a satellite and a linkage separation and unlocking device, and relates to the technical field of separation mechanisms for satellite-rocket or satellite-satellite separation. When the rope and the poke rod connected with the tensioning assembly lose constraint due to breakage of the rope, the linkage rod arranged on the mounting seat applies thrust to the linkage rod away from the separation unlocking mechanism under the action of the unlocking spring, and at the moment, the linkage rod pulls the poke rod to rotate by a certain angle on the lower cylinder, so that the rope is tensioned. At the moment, the radial constraint of the roller and the split nut is relieved; under the action of the unlocking spring, the linkage rod applies thrust to the poke rod located in the next separation unlocking mechanism to force the containing cylinder and the rotating cylinder to rotate in the lower cylinder; at the moment, a connecting stud in the corresponding separation unlocking mechanism is separated from the sectioning nut, and linkage unlocking is achieved in a reciprocating manner; the high-frequency impact at the whole mechanism separation moment is greatly reduced, the whole cost is effectively controlled, and the weight of the separation mechanism is greatly reduced.

    本发明提出了一种用于卫星的分离解锁机构及联动分离解锁装置,涉及星箭或星星分离的分离机构技术领域。当绳索与张紧组件连接的拨动杆因绳索断裂失去约束,设置在安装座上的联动杆在解锁弹簧的作用下,对联动杆施加一个向远离分离解锁机构的推力,此时的联动杆将拉动拨动杆在下筒上旋转一定角度,此时滚柱及分瓣螺母的径向约束解除;联动杆在解锁弹簧的作用下,对位于下一个分离解锁机构内的拨动杆施加推力迫使容纳筒以及转筒在下筒内旋转;此时,对应分离解锁机构内的连接螺柱与分瓣螺母完成分离,如此往复实现联动解锁;整体机构分离时刻的高频冲击大幅降低,整体成本得到有效控制,分离机构重量大幅降低。
