[0025] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0026] like Figure 1As shown, a folding method of a drone capture net and a folding method thereof include a net cabin 1 and a capture net 2; the center section of the capture net 2 after storage is placed in the capture net 2, and the end of the capture net 2 extends out of the capture net 2; the net cabin 1 includes a bulkhead 11, a partition 12, and a bottom plate 13, the bulkhead 11 is a cylinder formed by connecting four arc-shaped plates of the same size end to end, the bottom plate 13 is installed at one end of the bulkhead 11, the partition 12 includes four square plates, one end of the four square plates is evenly installed on the bottom plate 13, the partition 12 is placed in the bulkhead 11 and forms four cavities with the upper half of the bulkhead 11. The partition is used to isolate the corner bundling section, and the four corners of the capture net do not interfere with each other during the unfolding process. When unfolding, after the generator launches the traction block to fly out, the bundling section of the folded capture net is first pulled to unfold, and then the main body of the capture net is continued to be pulled to unfold.

[0027] like Figure 2 As shown, the capture net 2 includes a square net woven from a plurality of net ropes 22, and two diagonal lines of the square net are respectively fixed on a main rope 21, and both ends of the two main ropes 21 extend out of the square net and are fixedly connected to a traction block 23.

[0028] like Figure 4 As shown, the square net is wound on the main rope 21, the center of the capture net 2 is placed at the bottom of the net cabin 1, and the partition 12 is used to limit it in the net cabin 1, the four ends of the capture net 2 are neatly stacked in four cavities, and the four ends of the capture net 2 extend out of the net cabin 1 from the upper end of the bulkhead 11. First, the net ropes at the four corners of the capture net are folded into strips along the middle main rope, and the folded net ropes are tied to the main rope with fragile tape.

[0029] like Figure 3 As described above, the bulkhead 11, the partition 12, the bottom plate 13, and the column 14 are all easily detachably connected, and can be temporarily fixed with glue during the connection, or a thin-walled structure can be used at each connection to facilitate the collapse of the net compartment during the unfolding of the catching net.

[0030] like Figures 4 to 8 As shown, a method for folding a drone capture net and a net cabin comprises the following steps:

[0031] S1. At the same time, the four diagonal ends of the square net are respectively wrapped around the corresponding main rope 21 in the same direction and fixed with fragile adhesive tape 26;

[0032] S2. Stop when the middle parts of the two square nets touch each other. Figure 7 As shown, the length of the binding section is just equal to half the length of the side line of the net; the four ends of the catching net 2 are wound to form binding sections, and the middle of the catching net 2 naturally sags to form a central section;

[0033] S3, such as Figure 1As shown, the central section of the capture net 2 is placed in the bottom of the net cabin 1 in a circular manner, and then the partition 12 is installed in the net cabin 1;

[0034] S4, such as Figure 4 As shown, the four binding sections of the catching net 2 are folded and placed in four cavities respectively, and the ends of the main rope 21 are led out of the net cabin 1 respectively.

[0035] The capture net of the present invention adopts a square net, and the capture net is composed of four thicker "X"-shaped main ropes and a number of thinner net ropes, and each main rope is connected to a steel traction block. When the capture net is folded, the net ropes near the four corners are folded along the main ropes, and the folded net ropes are tied to the main ropes with fragile paper tapes until the four tied sections converge with the middle of the net. At this time, the length of the tied section is just equal to half the length of the net edge line. After the non-tied section of the capture net is folded in a circular manner and placed at the bottom of the capture net cabin, the detachable partition of the capture net is placed, and the upper half of the cabin is isolated into four areas. Then, the four tied sections are folded and placed in each area in turn, and the four tied sections of the net do not interfere with each other during the unfolding process. When unfolding, after the steel traction block flies out along the same plane, the tied section of the folded capture net is pulled to unfold. After unfolding, under the tension of the main rope, the fragile paper tape breaks, and the main rope continues to pull the capture net to unfold completely.
