The invention provides a rapid separation device based on memory alloy wire driving. The device comprises a driven end arranged on a butt joint star and a driving end arranged on a driving star. The driven end comprises an arc-shaped gasket, and a seam allowance is arranged on the arc-shaped gasket in a circumferential direction. The driving end comprises a shell, a locking rod, a hook, a loadingnut, a shifting fork, a bracket, a bearing ring, a memory alloy wire and an inclined block; the bottom of the bearing ring is supported on a boss of a bead cover; the top of the bearing ring is in contact with the bottom end of the inclined block arranged on the bracket; and the top end of the inclined block makes contact with the lower surface of the hook. When the memory alloy wire is powered on, the memory alloy wire is shortened to drive the bearing ring to rotate, constraint of the hook on the shifting fork is relieved through downward movement of the inclined block making contact with the top of the bearing ring, then constraint on the locking rod is relieved, so that separation and unlocking of the driving star and the butt-joint star are achieved. The separation device disclosed bythe invention realizes rapid separation, and is low in impact, energy-saving, environment-friendly, small in size, high in reliability and reusable.

    本发明提供了一种基于记忆合金丝驱动的快速分离装置,包括安装在对接星上的被动端和安装在主动星上的主动端,所述的被动端包括弧形垫片,在弧形垫片上周向设有止口;所述的主动端包括壳体、锁紧杆、钩、加载螺母、拨叉、支架、轴承环、记忆合金丝和斜块,轴承环的底部支撑在珠粒盖的凸台上,轴承环的顶部与设置在支架上的斜块的底端接触,所述的斜块的顶端与钩的下表面接触,记忆合金丝通电时,记忆合金丝缩短带动轴承环旋转,通过与轴承环顶部接触的斜块的向下移动解除钩对拨叉的约束,进而解除对锁紧杆的约束,实现主动星和对接星的分离解锁。本发明的分离装置,实现快速分离,且低冲击、节能环保、体积小、可靠性高、可重复使用。
