[0034] Embodiment one
[0035] The embodiment provides a kind of anti-UAV shrapnel, as shown in Figure Figure 1 Including projectile 1 and launch charge 2, launch charge 2 is assembled in the tail of projectile 1, for launching projectile, it includes cartridge 2.1, propellant 2.2, solid medicine sheet 2.3, solid medicine ring 2.4 and primer 2.5, the cartridge 2.1 is assembled in the tail of projectile 1, the propellant 2.2 is fixed in the cartridge 2.1 by solid medicine sheet 2.3 and solid medicine ring 2.4, the primer 2.5 is arranged at the bottom of the cartridge 2.1, for igniting propellant 2.2, high-pressure gas generated by propellant acts on projectile, so as to push projectile out of chamber.
[0036] As shown in Figure Figure 2 The projectile 1 includes bullet body 1.1, pressure limiting sheet 1.2, band 1.3, bullet support 1.4, shrapnel killing element 1.5, positioning support plate 1.6, jacking rod 1.7 and wind cap 1.8, wherein:
[0037] The pressure limiting piece 1.2 is pressed into the bottom of the elastic body 1.1 to block the fire transmission hole.
[0038] As attached Figure 2 and 4 As shown, the ammunition belt 1.3 is rotatably mounted on the projectile body 1.1. This rotatable design not only seals the gas within the barrel of the projectile, but also slides relative to the projectile body during firing, reducing the rotational speed of the projectile body and its internal components, thereby improving the accuracy of the shotgun's lethality. In a preferred embodiment, the ammunition belt can be made of PEEK, leveraging its excellent self-lubricating properties to reduce friction between the belt and the projectile body. In another preferred embodiment, a bushing is installed on the inner wall of a conventional ammunition belt to reduce friction between the belt and the projectile body.
[0039] The cartridge case 1.4 is arranged in the inner cavity of the projectile body 1.1, and a blind hole 1.4.0 for loading the shotgun killing element 1.5 is provided on the top thereof. The cartridge case 1.4 and the inner cavity of the projectile body 1.1 are clearance-fitted.
[0040] As attached Figure 2 and attached Figure 3 As shown, the outer diameter of the positioning plate 1.6 matches the inner diameter of the blind hole 1.4.0. It is circularly arranged with multiple retaining recesses 1.6.1 for retaining the shotgun-killing element 1.5. These recesses 1.6.1 are located on the upper and / or lower surfaces of the positioning plate 1.6. The shotgun-killing element 1.5 is arranged within the retaining recesses 1.6.1 of the positioning plate 1.6. Preferably, the shotgun-killing element 1.5 is a spherical shotgun-killing element, optionally including a tungsten ball. Accordingly, the retaining recesses 1.6.1 on the positioning plate 1.6 are spherical and match the surface of the spherical shotgun-killing element. The positioning plate 1.6 and shotgun-killing element 1.5 are layered within the blind hole 1.4.0 of the cartridge case 1.4 and supported by a push rod 1.7. The other end of the push rod 1.7 is connected to a wind cap 1.8, which is threadedly connected to the projectile body 1.1. Preferably, the push rod 1.7 is composed of a pressure plate 1.7.1 and a vertical rod 1.7.2. The outer diameter of the pressure plate 1.7.1 matches the inner diameter of the blind hole 1.4.0, and is used to support the positioning support plate 1.6. The pressure plate 1.7.1 is also provided with an exhaust hole to facilitate the pressure plate to enter the elastic support, and the other end of the vertical rod is inserted into the positioning hole of the wind hood.
[0041] As attached Figure 2 As shown, this embodiment preferably has two types of positioning plates, one is a positioning plate located at the bottom and top layers with limiting pits set on only one surface, and the other is a positioning plate located at the middle layer with limiting pits set on both surfaces.
[0042] The positioning support plate of this embodiment can make the shotgun killing elements arranged in an orderly manner in the cartridge case, and the positioning support plate also has a directional effect when the shotgun killing elements are separated from the cartridge case. After separation, the positioning support plate has a certain radial constraint effect on the shotgun killing elements, thereby improving the dispersion accuracy of the killing elements.
[0043] During firing, the high-temperature and high-pressure gas generated by the propellant breaks through the pressure-limiting plate and enters the projectile body, pushing the cartridge case and the shotgun killing element to fly out. The projectile body also continues to move in the barrel and fly out under the action of the gas. After flying a certain distance, the shotgun killing element and the positioning support plate separate from the cartridge case, and the killing element disperses, destroying the target.
[0044] Example 2
[0045] On the basis of the first embodiment, this embodiment further designs the cartridge case, as shown in the attached Figure 2 As shown, in this embodiment, multiple through-holes 1.4.1 are provided at the rear end of the sabot 1.4, allowing the bottom of the sabot to deform and compress to provide a cushioning effect, facilitating the separation of the positioning plate and the killing element from it. Specifically, the caliber and distribution of the openings are designed to match the projectiles within the sabot (the shotgun killing element and the positioning plate).
[0046] Design Principle: A hole in the bottom of a rigid body is equivalent to adding a spring of a certain stiffness. Within a certain range, a low spring stiffness facilitates separation of the sabot from the projectile. The size and distribution of the spring stiffness holes determine the spring stiffness. A sabot without holes is equivalent to having an extremely high stiffness at the bottom, which is almost indestructible. Adding holes reduces this stiffness, facilitating separation.
[0047] Example 3
[0048] On the basis of the first or second embodiment, this embodiment further designs the projectile, as shown in the attached Figure 2 As shown, the projectile body 1.1 is composed of an upper projectile body 1.1a and a lower projectile body 1.1b, which are threadedly connected to each other. The elastic band 1.3 is inserted into the threaded end of the lower projectile body 1.1b and is then restrained by the upper projectile body 1.1a. This embodiment adopts a split design for the projectile body, which facilitates the assembly of the elastic band. This assembled structure can reduce the manufacturing difficulty.
[0049] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
