The invention provides an explosive bolt collecting device, an aerospace craft separation system and an aerospace craft, the collecting device is installed on a separation body of the aerospace craft, the collecting device is provided with a collecting hole, the collecting hole is provided with a collecting opening, and the collecting hole extends inwards from the collecting opening in the first direction; wherein the sectional area of the collecting hole is gradually reduced in the first direction. When the separated body of the aerospace craft is separated, the explosive bolt is detonated, the broken connecting piece flying out of the explosive bolt at a high speed moves in the collecting hole in the first direction, the broken connecting piece of the explosive bolt extrudes the inner wall face of the collecting hole to form self-locking, the broken connecting piece cannot rebound, and the risk that normal work of other equipment is affected is reduced; and meanwhile, the risk that the broken connecting piece rebounds back to the mounting hole of the explosive bolt is reduced, the separation system is high in working reliability, and smooth and safe separation of the separated body of the aerospace craft is facilitated.

    本申请提供一种爆炸螺栓的收集器件、航天飞行器分离系统和航天飞行器,该收集器件安装于航天飞行器的分离体,该收集器件设置有收集孔,收集孔具有收集口,收集孔从收集口处沿第一方向向内延伸;其中,沿第一方向,收集孔的截面积逐渐减小。在航天飞行器的分离体分离时,爆炸螺栓起爆,爆炸螺栓高速飞出的断裂连接件在收集孔内沿第一方向运动,爆炸螺栓的断裂连接件挤压收集孔的内壁面形成自锁,断裂连接件不会产生反弹,降低影响其他设备正常工作的风险,同时降低断裂连接件反弹回爆炸螺栓的安装孔的风险,该分离系统工作可靠性高,有利于航天飞行器的分离体顺利安全分离。
