The invention relates to the technical field of aerospace equipment, and provides a space flexible net and a locking and releasing mechanism. Wherein the space flexible net comprises an elastic ring frame and a limiting ring; a flexible net is installed in the elastic ring frame, the elastic ring frame has an unfolded state and a folded state, and the elastic ring frame is in a plane shape in the unfolded state; when the elastic ring frame is in the folded state, the elastic ring frame can elastically deform to be twisted and folded to form a plurality of sub-ring parts which are arranged in sequence, and every two adjacent sub-ring parts are coaxial and stacked; the limiting ring is detachably installed on the elastic ring frame in the folded state so as to limit the multiple sub-ring parts to rotate in the direction away from one another. And when the limiting ring is separated from the elastic ring frame, the elastic ring frame is switched from the folded state to the unfolded state under the elastic acting force of the elastic ring frame. After the elastic ring frame is folded, the occupied space is small, the elastic ring frame can be automatically unfolded under the action of the elastic force of the elastic ring frame, and the unfolded elastic ring frame has a supporting effect on the flexible net, so that the flexible net can be kept in an unfolded state for a long time to capture an object.
本申请涉及航天设备技术领域,提供一种空间柔性网及锁定释放机构。其中空间柔性网包括弹性环框和限位环;弹性环框内安装有柔性网,弹性环框具有展开状态和折叠状态,弹性环框在展开状态时呈平面状;弹性环框在折叠状态时,弹性环框能弹性变形而扭转折叠形成多个依次排列的子环部,每相邻的两个子环部同轴且层叠设置;限位环可拆卸的安装于折叠状态的弹性环框上,以限制多个子环部朝相互远离的方向转动;限位环与弹性环框脱离时,弹性环框在自身弹力作用力下由折叠状态切换至展开状态。弹性环框折叠后占用空间小,弹性环框能在自身的弹力作用下自动展开,展开的弹性环框对柔性网具有支撑作用,使柔性网能长时间保持张开状态以捕捉物体。
