Technical Field
[0001] The present invention relates to the technical field of anti-UAV light weapons, and in particular to a multi-projectile cluster launch combination structure for anti-UAV. Background Art
[0002] With the changes in the form of warfare, distributed "low, slow, small" drones are increasingly widely used on land battlefields, producing great military effects. In the future, they will seriously threaten ground equipment, etc. Low-cost drones have already caused fatal damage to individual combat units. Light drones are small in size and light in weight, so their ability to resist damage is limited. The kinetic energy of firearms is enough to effectively damage drones. However, due to the small size and flexible flight characteristics of drones, automatic rifles, machine guns and other firearms using single-headed bullets have a low probability of hitting drones. One of the existing countermeasures for individual combat units is to use shotguns to intercept targets. A shotgun can fire multiple projectiles in one shot. These projectiles instantly form a scattered area to cover the drone, which can effectively improve the hit rate of the drone. The shotguns currently used are mostly 12-gauge shotguns, with a steel ball diameter of 4mm and a number of 20 to 30. Since the total volume of the shotgun is fixed, the more projectiles there are, the smaller the diameter of the projectile is (the projectile is generally spherical), and the smaller the diameter, the shorter the flight distance of the projectile, and the greater the power of the projectile. The smaller it is, the less likely it is to penetrate the drone's body, and thus cannot cause damage to the drone. On the other hand, the dispersion control of shotgun shells is not ideal. Since many projectiles are not constrained during the launch process, squeezing and collisions between the projectiles are inevitable during the launch process, and these collisions are not head-on collisions. Therefore, the direction of movement of the projectiles will deviate from the original flight path, causing the dispersion to become larger. At the current shotgun shell, at 100 meters, the distance between the projectiles is much larger than the drone, and 100% hit rate on the drone cannot be guaranteed. Summary of the Invention
[0003] The purpose of the present invention is to overcome the limitations of current rifles and shotguns in anti-UAV applications and to provide a multi-projectile cluster launch combination structure for anti-UAV applications, which is easy to use, accurate in striking, and highly adaptable.
[0004] The object of the present invention is achieved like this: A multi-projectile cluster launch combination structure for anti-UAV, comprising an ammunition component (1) and a launch device (2).

DETAILED DESCRIPTION
[0017] The embodiments of the application will be further described in detail below with reference to the drawings, It should be noted that the launcher adapted by the application is composed of a barrel assembly, a magazine launcher assembly and a stock, the ammunition component 1 and the shotshell in the prior art are launched in a similar way, the magazine-launcher assembly, the stock and other components are similar in structure to the single-shot grenade launcher, the butt-type shotguns and other firearms, and have the same functions, thus are not within the scope of the application and will not be described here.
[0018] As Figure 1 shown in a kind of multi-projectile cluster launching combined structure for anti-UAV, the device is mainly composed of ammunition component 1 and launching device 2;Wherein ammunition component is composed of shell 1-1 and bullet seat 1-2 etc., launching device is mainly composed of launching tube seat 2-1, launching tube 2-2 and tube frame 2-3 etc., As Figure 2 shown in a kind of multi-projectile cluster launching combined structure for anti-UAV, multiple launching tubes 2-2 are evenly distributed on launching tube seat 2-1 with certain rules, preferably, in order to facilitate quick loading, facilitate the alignment of ammunition component 1 and launching tube, the distribution mode of launching tube should be evenly distributed with launching tube seat 2-1 axis as center, can distribute multiple rounds, with the present embodiment as an example, there are 13 launching tubes, arranged in 3 rounds, the first round is located at the center of launching tube seat, the number is 1, the second round is evenly distributed with 6 launching tubes with launching tube seat center as axis, the included angle is 60 °, the third round is also evenly distributed with 6 launching tubes with launching tube seat as center, the included angle is also 60 °, to improve space utilization, the third round of launching tubes should be staggered with the second round, As Figure 2The illustrated structure is a multi-projectile cluster launch combination structure for anti-UAV use. The outer cylindrical surface 2-5 of the launch tube seat and the outer cylindrical surface 2-6 of the front tube rack are used for radial positioning of the launch device inside the launcher barrel. The side through hole 2-7 is used for axial positioning of the tube rack. The side through hole 2-7 can be connected to the barrel hole of the launcher by a pin to prevent it from escaping from the launcher barrel. The tail positioning protrusion 2-8 of the launch tube seat is used for axial positioning of the entire launch device. The groove 2-4 of the launch tube seat can facilitate the shooter to remove the bullet. The cluster launch device can be installed in the launcher barrel as a whole, and is axially positioned by the tail positioning protrusion. The front end of the launch tube is covered with a tube rack, and the tube rack can control the angle of convergence of the launch tube. like Figure 3 As shown, the cartridge case 1-1 and the bullet seat 1-2 are connected by threads, and blind holes 1-3 for positioning are evenly distributed at the front end of the bullet seat. When the ammunition is installed, the positioning pins 2-9 fall into the positioning blind holes, so that the steel ball holes of the bullet seat are completely aligned with the launch tubes one by one. A number of through holes 1-5 are evenly distributed axially on the bullet seat. The arrangement order of the through holes 1-5 on the bullet seat is consistent with the order of the launch tubes. The steel balls 1-6 are placed inside them. The tail of the through hole is a stepped hole 1-7 to limit the movement of the steel balls toward the tail of the projectile. A sealing piece 1-4 is provided at the front end of the through hole. The end face of the sealing piece is flush with the end face of the head of the bullet seat, which completely limits the displacement of the steel balls in a static state. like Figure 3 As shown, in this embodiment, each through hole is equipped with 6 projectiles, with a total of 13 through holes. Therefore, each fixed ammunition component can be equipped with 78 projectiles. In actual use, the number of through holes and the number of projectiles can be increased or decreased as needed. Optimally, in order to improve the energy utilization of gunpowder and prevent moisture, a sealing structure is designed in front of the cylinder, and a bullet support for sealing the air can also be designed behind the last projectile. like Figure 4 As shown, the launch tube and the launch tube seat are connected by a thread 2-10, and the locating pin 2-9 is interference fit with the launch tube seat. The ejector 2-13 is installed in the stepped through hole of the launch tube. The rear part of the ejector is followed by the ejector spring 2-12 and the screw 2-11. The screw is connected to the launch tube seat through a thread. When the ammunition is fully installed, the locating pin falls into the locating hole of the bullet seat. At the same time, the ejector will press against the front end plane of the bullet seat 1-2 and compress the ejector spring. When the shooting is completed and the chamber is opened, the ejector will push the entire ammunition backward a short distance under the action of the ejector spring, which is convenient for taking and changing bullets. The ejector 2-13 acts on the front end of the bullet seat. The ejector and the positioning blind hole are on different circumferences to ensure that the ejector can always act on the front end plane of the bullet seat; the sealing piece 1-4 is flush with the front end of the bullet seat, and the locating pin 2-9 will not fall into the steel ball hole by mistake, so as to ensure accurate positioning and avoid chamber explosion. Several launch tubes 2-2 can also be manufactured in an integrated manner using processes such as powder metallurgy, additive manufacturing, and injection molding. They can be designed as a whole with the launch tube base 2-1, the tube rack 2-3, etc., with a simpler structure. The inside of the launch tube seat is the chamber, and the ammunition is positioned in the chamber by the head of the bullet seat. A stepped hole and a through hole are designed on the axis of the launch tube seat. The ejector 2-13, ejector spring 2-12 and screw 2-11 are installed in the stepped hole. The ejector can move axially in a small range in the stepped hole; the positioning pin 2-9 is installed in the through hole with interference fit to locate the position of the ammunition in the chamber, so that the steel ball hole and the launch tube are aligned one by one to avoid explosion during firing. After the single shot is completed, the ejector will push the ammunition back a short distance to facilitate the shooter to take out and replace the ammunition. The present invention can also be installed on a grenade launcher for use through conversion. Its essence is to use the launch tube of the grenade launcher as the outer tube of the launch tube, assemble the launch tube seat, launch tube and tube rack and other parts into a conversion kit, and after the conversion kit is installed on the launch tube of the grenade launcher, the grenade launcher can be used to launch cluster munitions. The firing channels of multiple launch tubes are connected together through the same air chamber in front of the warhead seat (inside the launch tube seat), which can launch steel balls with larger diameters, and the number of steel balls is twice that of ordinary shotgun shells, which can better form a larger net interception for drones. At the same time, multiple launch tubes can be converged at a certain angle to improve the accuracy of hitting drones; after firing, the gunpowder gas expands in the air chamber and is diverted to each launch tube, while pushing the projectiles in each tube out of the launch tube. Due to the large number of launch tubes and the large number of projectiles in each launch tube, the number of projectiles launched at one time is sufficient. Since there is no volume limit for shotgun shells, the diameter of the projectiles can also be larger, ensuring the flight distance and power of the projectiles. Since the projectiles are well constrained in the launch tubes, the projectiles collide with each other along the launch tube's center, which does not affect the flight trajectory of the projectiles. At the same time, through these center collisions, the projectiles in the same launch tube can reach the same flight speed, which is also conducive to the consistency of the projectile's flight path.
[0019] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
