DETAILED DESCRIPTION

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

The traction rope 1 is used to tow the three-dimensional net 2, that is, it is responsible for dragging the combination after the target object is captured; it also includes a closing module 3, which is connected to the net mouth end of the three-dimensional net 2 and is used for unfolding and closing the three-dimensional net 2.

[0024] The three-dimensional net 2 is made of fully flexible tethers. The three-dimensional net 2 includes a net body weft rope 2-2, a net body warp rope 2-3, and a net tail sealing rope 2-5. Multiple net body weft ropes 2-2 and multiple net body warp ropes 2-3 are arranged in a staggered manner to form the net structure. The net body weft rope 2-2 at the net opening is marked as the net opening weft rope 2-1. The net opening weft rope 2-1 is installed with a closing module 3. A rigid ring 3-1 is fixedly connected to the net opening weft rope 2-1. The net body weft rope 2-2 at the net tail is marked as the net tail weft rope 2-4. The net tail sealing rope 2-5 is fixedly connected to the net tail weft rope 2-4. The net tail sealing rope 2-5 is fixedly connected to the traction rope 1.

[0025] The net tail sealing rope 2-5 comprises two ropes connected in a cross manner, and both ends of the two ropes are fixedly connected to the net tail weft rope 2-4.

[0026] The shape of the net body weft rope 2-2 in the fully expanded state is circular. The shape of the three-dimensional net 2 in the fully expanded state is a truncated cone.

[0027] The closing module 3 includes a rigid ring 3-1, a torsion spring hinge 3-2 and an arc-shaped sealing rod 3-3; the rigid ring 3-1 is a rigid circular ring, the same size as the mesh weft rope 2-1, and is fixedly connected to the mesh weft rope 2-1; four torsion spring hinges 3-2 are installed on the rigid ring 3-1 at intervals along the circumference, one side of each torsion spring hinge 3-2 is fixedly connected to the rigid ring 3-1, and the other side of each torsion spring hinge 3-2 is fixedly connected to one end of the arc-shaped sealing rod 3-3, and the arc-shaped sealing rod 3-3 is arranged along the radial direction of the three-dimensional net 2.

[0029] Before capture, the traction rope 1 and the three-dimensional net 2 are in a compressed and folded state;

[0030] During capture, the task platform launches the system toward the target at high speed. The three-dimensional net 2 is unfolded into a three-dimensional state under the action of the inertial force. The target contacts the arc-shaped sealing rod 3-3 of the closing module 3. The arc-shaped sealing rod 3-3 rotates toward the three-dimensional net 2 under the action of the inertial force of the target. The target completely enters the rope net. Then, the arc-shaped sealing rod 3-3 returns to the equilibrium position under the action of the torsion spring of the torsion hinge 3-2, and the rope net is closed.

[0031] After capture, the task platform controls and drags the rope assembly through the traction rope 1 to complete the capture task.
