The invention belongs to the field of space debris cleaning, and particularly relates to a mechanical rope net pressing and releasing mechanism which comprises an upper fixing ring, a middle fixing ring, a lower fixing ring, a plurality pressing plate and a torsion spring; the pressing plates, the middle fixing ring and the lower fixing ring are adopted to form a four-connecting-rod mechanism through connecting rods, and the upper connecting point, close to the pressing plates, of the four-connecting-rod mechanism is connected with the upper fixing ring through an upper connecting rod. When the upper fixing ring is pressed downwards, the four-connecting-rod mechanism pushes the pressing plates to move forwards, and the multiple pressing plates are spliced into a circle to press the rope net. A torsional spring is arranged at the joint of the lower portions of the pressing plates and short connecting rods, when pressure on the upper fixing ring disappears, the pressing plates push the four-connecting-rod mechanism to be lifted under the action of the torsional springs, and the pressing plates move outwards to open the pressed rope net. The mechanical rope net pressing and releasingmechanism is a pure mechanical device, the releasing mechanism is opened through the cabin opening action, the independent rope net releasing process is omitted, and therefore the reliability of aerospace products is improved.

    本发明属于空间碎片清理领域,具体涉及一种机械式绳网压紧释放机构。包括上固定圈,中固定圈,下固定圈,压紧板和扭簧;压紧板为多个,压紧板和中固定圈、下固定圈之间通过连杆形成四连杆机构,四连杆机构靠近压紧板的上部连接点通过上连杆与上固定圈连接;当上固定圈向下压时,四连杆机构推动压紧板向前移动,多个压紧板拼接成一个圆周将绳网压紧;压紧板下部与短连杆的连接处设有扭簧,当上固定圈上的压力消失时,压紧板在扭簧作用下,推动四连杆机构抬起,压紧板向外运动打开被压紧绳网。本发明是一种纯机械装置利用开舱动作打开释放机构,减少单独释放绳网过程,从而提高航天产品可靠性。
