Description

Technical Field

[0001] The utility model relates to a rocket net pneumatic launching device, belonging to the technical field of unmanned aerial vehicle countermeasures. Background Art

[0002] With the rapid development of the drone market, drones will undoubtedly bring hidden dangers of security and economic losses to society in special places such as civil aviation airports, confidential places, and public places. They may also bring security issues such as affecting aviation order, intruding into sensitive areas, and dropping prohibited items. Therefore, civil drones must be managed in an orderly manner and effective measures must be taken to capture harmful, dangerous and suspicious drones.

[0003] When capturing illegal drones, a capture net is often launched. However, in the prior art, the capture net is often launched by means of gunpowder or the like. For example, the invention patent with application number CN202210173118.9 discloses a precise launch system for capturing drones. This technical solution uses a rocket as a power device to launch the capture net, which has a high cost and increases the launch cost. It is not conducive to frequent and multiple use and is not universal. It is also highly dangerous and makes the overall volume larger and the weight heavier, making it inconvenient to carry.

[0004] In the prior art, there is also a capture net launching technology using pneumatic launch, for example, a known projection capture net device includes a container located inside the device, the container includes a gas expansion power source, a folding capture net and a folding component, and also includes a weight fixed to the periphery of the capture net (see patent application: JP2002-355323, publication date: 2002-12-10).

However, the basic disadvantage of this device is that it only has a small effective range and is not suitable for long distances.

[0005] Therefore, we propose a four-tube rocket net electromagnetic launch device. Utility Model Content

[0045] Specifically, the gas bomb 4 includes a gas cylinder 24 and a bullet 25. A screw 26 is provided on the top of the gas cylinder 24. The screw 26 is screwed and fixed to the bottom of the bullet 25. The top of the bullet 25 is streamlined, and a weak seal that is easily punctured is provided on the bottom of the gas cylinder 24.

[0046] Specifically, the capture net 5 is rectangular, and the four corners of the capture net 5 are connected to the tail of the gas bomb 4 through ropes.

[0050] The working principle of an embodiment of the utility model is as follows: when shooting, the utility model adjusts the inclination angle of the gun barrel 3, fixes it through the folding bracket 6, loads the gas bullet 4, aims at the target through the aiming device 27, and releases it immediately after pulling the trigger 15. The top end of the trigger 15 presses the connecting rod 20 forward, so that the sealing block 18 moves forward to open the output channel of the valve body 16, and the high-pressure gas is output from the air chamber 8 to the outside. The power air pipe 30 provides high-pressure gas for the firing component 7, squeezes the sealing slider 11 to move forward, and the spike portion 12 extends out of the small hole at the front end of the mounting tube 10 to pierce the gas bullet 4. The sealing slider 11 moves forward until the front side of the air outlet hole of the mounting tube 10 to expose the air outlet hole. After releasing the gas, the elastic component 13 makes the sealing slider 11 rebound to the tail end and seal the air outlet hole.

[0051] After the gas bullet 4 is punctured, it releases high-pressure gas, shoots forward and carries the capture net 5 to fly, unfold, and pounce on the target.

At the same time, since the two lower barrels 3 output gas to the outside, the ejection speed of the gas bullets 4 from the two lower barrels 3 is slower than that from the upper two barrels 3, thereby ensuring the net shape of the capture net 5 during flight after the gas bullet 4 is ejected.
