The invention provides a flying anchor capable of penetrating and fixing space debris. Comprising a shell, a barb fixing rod, barbs, a wedge-shaped block, a U-shaped pushing plate, a limiting plate and a self-locking rod. The shell comprises an anchor head, a wedge-shaped stop block and an anchor body, the barbs are rotationally connected with the shell through the barb fixing rod, and the barbs can rotate towards the outer side around the fixing rod; the wedge-shaped surface of the wedge-shaped block clings to the wedge-shaped surface of the wedge-shaped stop block, and the other end of the wedge-shaped block is embedded into a groove of the U-shaped push plate; the self-locking rod penetrates through a hole in the middle of the limiting plate to be fixedly connected with the U-shaped pushing plate, and the limiting plate is fixedly connected with the shell; in the process that the flying anchor makes contact with fragments, the wedge-shaped block generates a relative speed at which the wedge-shaped block continues to move towards the anchor head relative to the shell, the barbs are extruded in the relative movement process, the barbs are opened outwards to lock the fragments, and meanwhile the wedge-shaped block becomes large in the radial direction in the extrusion process and can also play a role in fixing the fragments. The device is simple in structure, low in manufacturing cost, convenient to operate and capable of achieving penetration and fixation of space debris.

    本发明提供了一种可侵彻和固定空间碎片的飞锚。包括壳体、倒刺固定杆、倒刺、楔形块、U形推动板、限位板、自锁杆;壳体包括锚头、楔形阻挡块和锚体,倒刺通过倒刺固定杆与壳体转动连接,倒刺可绕固定杆向外侧转动;楔形块楔形面与楔形阻挡块楔形面紧贴,另一端嵌入U形推动板凹槽中;自锁杆穿过限位板中间的孔与U形推动板固连,限位板与壳体固连;飞锚在接触碎片过程中,楔形块产生一个相对于壳体继续向锚头运动的相对速度,在相对运动过程中挤压倒刺,并使倒刺向外张开实现对碎片的锁定,同时楔形块在挤压过程中径向变大也可以起到固定碎片的作用;本发明结构简单,造价低,操作方便,可实现对空间碎片的侵彻和固定。
