[0002] With the development of science and technology, drones have gradually been widely used in various occasions in life. There are many "illegal" drones that endanger public safety. Drones have been used extensively in wars, causing considerable losses. Therefore, the development of anti-drone equipment has become a popular research direction.

[0003] Most of the existing contact anti-UAV technologies use a capture net to launch at the UAV, which can effectively stop the UAV by interfering with the rotor blades, with high accuracy and low risk of collateral damage.

Rocket engines have the advantages of strong power, simple and reliable structure, and rocket-related technologies can be applied to equipment for intercepting UAVs. However, there is still a gap in this research field. At present, there is no anti-UAV device that can install and launch multiple rockets at the same time. Utility Model Content

Figure 2 and 6 As shown, a sealed hatch cover 5 is installed on the side of the sealed cabin 32 away from the centralized loading plate 3. Figure 1 As shown, a propellant package installation position 321 is provided on the side wall of the centralized loading plate 3 in the sealed cabin 32, and the propellant package installation position 321 is located in the middle of the centralized loading plate 3. The propellant package installation position 321 is formed by surrounding and connecting the centralized loading plate 3 with four limiting bosses. The propellant package installation position 321 has a built-in propellant package 4. The sealed cabin cover 5 is provided with an ignition copper cap installation position 51, and the ignition copper cap 8 is located in the ignition copper cap installation position 51. The ignition copper cap 8 is installed in the ignition copper cap installation position 51 by interference fit, and the impact hole 33 is opened on the side wall of the ignition copper cap installation position 51, as shown in FIG. Figure 3 As shown, the ignition platform 6 is installed on the sealed hatch 5, and is connected by internal and external threads.
