Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0025] Example: Anti-drone interceptor shotgun, comprising a metal base 1, a cartridge case 2, propellant 3, a sabot 4, and a warhead 5 equipped with a net, as shown in the attached diagram. Figure 1 and 2 As shown; the metal base 1 is disposed at the bottom end of the cartridge case 2, and a sealing piece 6 for sealing is installed at the open end of the cartridge case 2. The sealing piece 6 includes a piece body 8, as shown in the attached figure. Figure 7As shown, the circumferential surface of the piece 8 has an annular edge 9 that contacts the inner side of the cartridge case 2. The piece is inserted into the cartridge case, and the annular edge fits tightly against the inner wall of the cartridge case opening, achieving a certain degree of interference fit, which can improve the sealing performance and prevent the projectile from falling out. The sabot 4 is set inside the cartridge case 2, the projectile 5 is set on the upper part of the sabot 4, and the propellant 3 is set on the lower part of the sabot 4. The sabot can not only stably and effectively separate the propellant from the projectile, but also tightly seal the internal gas, ensuring the stability and reliability during the firing process. The metal base At the bottom center of the base 1 is a primer 7 that abuts against the propellant 3. The primer plays a key role in the entire anti-drone intercept shotgun system. It is located inside the metal base and is in close contact with the propellant. When the external environment provides a suitable trigger, the primer will quickly generate high-temperature and high-pressure gas. This gas can instantly ignite the propellant inside the cartridge case. The combustion of the propellant produces a large amount of gas. The rapidly expanding gas forms a powerful thrust. This thrust acts on the sabot, thereby propelling the warhead out of the cartridge case at high speed and flying towards the target drone, completing the interception operation.
[0026] The warhead 5 includes a Kevlar fiber mesh 10, as shown in the attached image. Figure 5 As shown, lead blocks 11 are connected to the ends of the Kevlar fiber mesh 10. Multiple lead blocks 11 are assembled into a disc block 21. The disc block 21 is set on the upper part of the sabot 4. After the Kevlar fiber mesh is unfolded, it is a rectangular mesh. The specific structure is shown in the attached figure. Figure 6 As shown; after the warhead is launched, the lead blocks, with their weight, maintain a stable trajectory during flight, guiding the warhead's flight direction. A Kevlar fiber mesh is attached to the lead blocks. As it approaches the drone, the mesh rapidly unfolds, like a large net, thanks to the kinetic energy of the projectile. Due to the high strength and wear resistance of Kevlar fibers, once the mesh contacts the drone, it can entangle and damage critical components such as the drone's propellers, interfering with its flight control and causing it to lose balance and flight capability, thus achieving the purpose of intercepting and countering the drone. In this embodiment, four lead blocks are used, corresponding to the four corners of the Kevlar fiber mesh.
[0027] The sabot 4 includes a main body 22 disposed inside the cartridge case 2, as shown in the attached figure. Figure 4 As shown, the lower end of the main body 22 has a spacer section 23, and the lower part of the spacer section 23 has a positioning disk 24; the main body 22 has a main chamber 25 for positioning the projectile 5, and the spacer section 23 has an intermediate channel 26 that communicates with the main chamber 25. The lower end of the intermediate channel 26 communicates with the groove of the positioning disk 24. The propellant 3 is in contact with the positioning disk 24, and the end of the positioning disk is in contact with the propellant. After the propellant is detonated by the primer, part of the gas generated will act on the sabot, and the sabot will push the projectile out of the cartridge case. Part of the gas will also act on the projectile through the intermediate channel, causing the projectile to separate from the sabot.
[0028] The cartridge case 2 includes a shell 27, and the bottom of the shell 27 has a base 28, as shown in the attached figure. Figure 3 As shown, the sabot 4 is disposed inside the housing 27, and the base 28 has a through groove 29 through which the primer comes into contact with the propellant; the metal base 1 includes a ring 30 that fits into the base 28, as shown in the attached figure. Figure 8 As shown, the ring 30 has a central groove 32 for placing the primer 7 in the middle. The ring of the metal base holds the chassis in place, and the primer is placed in the central groove. The entire metal base is a one-piece molded structure. The edge of the ring 30 has a conical edge 31, which provides stable support for the cartridge case, making the entire shotgun structure stable. The primer placed in the base is the starting device for initiating the firing process. By contacting the propellant, the energy generated after being excited ignites the propellant, providing a power source for the shotgun firing. Moreover, the conical edge design makes the projectile more stable when placed on a flat surface, effectively improving the convenience and safety in the stages of storage, transportation, and preparation for use, and reducing the risk of accidents caused by unstable placement.
[0029] The working principle of this utility model is as follows: When anti-drone interception of shotgun shells is required, the trigger of the launching device is pulled first. The firing pin of the launching device violently strikes the primer 7 at the center of the bottom of the metal base 1. The chemical agent inside the primer 7 undergoes a rapid chemical reaction under the impact, instantly generating a large amount of high-temperature and high-pressure gas. This gas quickly passes through the gap between the metal base 1 and the slot 29 of the cartridge case 2 chassis 28 and enters the interior of the cartridge case 2. The high-temperature and high-pressure gas comes into contact with the propellant 3 located in the groove of the positioning plate 24 at the lower part of the sabot 4, and immediately ignites the propellant 3. The propellant 3 begins to burn violently, generating an even larger amount of gas. This gas expands rapidly in the limited space of the cartridge case 2, forming a strong pressure. The high-pressure gas generated by the burning propellant 3, with the projectile 5 placed on top, causes the sabot 4 to be pushed upwards first under this strong pressure. The main body 22 of the sabot 4 tightly wraps around the projectile 5. Under the action of the upward push, the sabot 4 drives the projectile 5 to move upwards together. The lead blocks 11 are assembled into a disc block 21. Due to its large mass, it can maintain a relatively stable flight attitude at the moment of separation from the sabot 4 and the start of flight, relying on its own inertia and initial thrust, providing stable flight direction guidance for the entire warhead 5. As the warhead 5 flies at high speed toward the target drone, when it approaches the drone, due to the huge kinetic energy accumulated during the flight, the Kevlar fiber net 10 connected to the end of the lead block 11 quickly unfolds. The Kevlar fiber net 10 covers the drone like a large net. Kevlar fiber has high strength and wear resistance. Once the fiber net comes into contact with the drone, it will quickly wrap around and damage the drone's propeller and other key components, interfere with the drone's flight control system, and cause the drone to lose balance and flight ability, ultimately achieving the purpose of intercepting and countering the drone. After the sabot 4 pushes the warhead 5 out, it will complete the subsequent actions in a predetermined manner inside or outside the launching device, such as falling to the ground. The whole process efficiently and quickly achieves the interception of the "black flight" drone.
[0030] The above embodiments merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. Furthermore, in these embodiments, "up," "down," "left," "right," "front," and "back" represent relative positions only, not absolute positions. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
