[0020] The present invention is further described below in conjunction with the accompanying drawings.

[0021] First embodiment

[0022] like Figure 1-2 As shown, embodiment 1 discloses a reusable capture net projecting device, comprising: a launcher 1 and a projecting unit 2 detachably arranged at the excitation end of the launcher 1, the projecting unit 2 comprising shells 21a and 21b, in which a capture net loading assembly and a kinetic energy assembly are detachably arranged in sequence from one end close to the launcher 1 to the other end far from the launcher 1, the capture net loading assembly is loaded with a pre-installed capture net, the kinetic energy assembly is used to store propellant, the launcher 1 excites the kinetic energy assembly to generate thrust, thereby projecting the capture net preset in the capture net loading assembly.

[0025] Based on the above structure, Figure 1-2 As shown, when using the capture net projection device, firstly, the end of the shell 21a close to the launcher 1 is screwed to the excitation end of the launcher 1 through the internal threaded hole, and then the launcher 1 is triggered, and the excitation end of the launcher 1 triggers the primer 33a, and the primer ignites the propellant in the cavity 31a, and the propellant generates kinetic energy to launch the capture net loaded inside the cylinder 22a, while the cylinder 31a and the propellant shell 3a are retained in the shell 21a. When it is recycled, the threaded connection between the cylinder 31a and the shell 21a is released, and then the threaded connection between the propellant shell 3a and the connecting cylinder 23 is released. At the same time, a new propellant shell 3a is threadedly connected to the new connecting cylinder 23, and a new capture net package is filled into the cylinder 22a, and then the cylinder 22a and the shell 21a are screwed again. At the same time, in actual use, some cylinders 22a with capture net packages filled inside can be prepared in advance, and the connecting cylinder 23 of the cylinder 22a is also installed with unused propellant shells 3a. When the first capture net is launched, the cylinder 22a together with the propellant shell 3a is directly taken out, and the pre-prepared cylinder 22a is reloaded, so as to carry out a second launch.

[0026] Second embodiment

[0027] like Figure 3 As shown, the difference between Example 2 and Example 1 is that the capture net filling assembly includes a cylinder 22b with a capture net bag filled therein, the outer wall of the cylinder 22b is fitted and slidably connected to the inner wall of the shell 21b, and the outer wall of the cylinder 22b away from the launcher 1 is threadedly connected to the inner wall of the shell 21b away from the launcher 1, the kinetic energy assembly includes a propellant shell 3b whose outer wall is threadedly connected to the inner wall of the shell 21b at one end close to the launcher 1, a cavity 31b for storing propellant is provided in the propellant shell 3b, the end of the propellant shell 3b close to the launcher 1 is provided with a mounting hole 32b whose inner wall is threadedly connected to the excitation end of the launcher 1, the inner wall of the mounting hole 32b is communicated with the inner wall of the cavity 31b, a primer 33b is fixedly installed at the end of the mounting hole 32b close to the cavity 31b, and a launching hole 34b communicated with the inner wall of the cavity 31b is provided at the end of the propellant shell 3b away from the launcher 1.

[0028] Based on the above structure, Figure 1 and 3As shown, after using the capture net projection device, release the threaded connection between the cylinder 22b and the shell 21b, release the threaded connection between the mounting hole 32b and the excitation end of the launcher 1, and release the threaded connection between the propellant shell 3b and the shell 21b. Then, re-thread the new cylinder 22b pre-filled with the capture net bag into the shell 21b, and re-screw the new propellant shell 3b into the shell 21b.

[0030] Further, such as Figure 2-4 As shown, in order to prevent the capture net from being damaged when the gunpowder is ignited, a propulsion hood 221 is slidably arranged inside the cylinder 22a, 22b. The kinetic energy generated when the gunpowder is ignited drives the propulsion hood 221 to launch the capture net.
