The entire test device can perform bullet changing operations from outside the test box 100, without going into water and is not affected by the water depth, and is easy to operate.

[0021] The test box 100 in this embodiment is filled with water, and ice cubes are floating on the water surface. By observing the ice crack propagation process and damage mode, the movement posture and ballistic trajectory of the projectile, the purpose of studying the efficient ice breaking of the projectile is achieved.

[0022] The projectile launching assembly 200 in this embodiment includes a gun barrel 210, a high-pressure gas source 220, a supporting plate 212 and a drainage member 240. The gun barrel 210 is arranged in the test box 100 with the muzzle facing the water surface. A loading port 211 is formed on the side wall of the gun barrel 210.

[0028] In order to drain the water in the hose 222 , the connection point between the hose 222 and the transfer box 221 in this embodiment is lower than the connection point between the hose 222 and the air compressor 223 .

[0029] The bullet changing assembly 300 in this embodiment includes a bullet changing sleeve 310 and a bullet feeding piece. The bullet changing sleeve 310 is fixedly arranged in the test box 100. The barrel 210 is built into the bullet changing sleeve 310 and is slidably connected with the bullet changing sleeve 310. A bullet feed port 311 is opened on the side wall of the bullet changing sleeve 310. The feeding end of the bullet feeding piece is located outside the test box 100.

One end of the bullet feeding cylinder 320 is located outside the test box 100, and the other end of the bullet feeding cylinder 320 extends into the test box 100 and is connected to the bullet feeding port 311. The push rod 340 is arranged outside the test box 100, and the push rod 340 extends into the bullet feeding cylinder 320 and is slidably and sealedly connected to the bullet feeding cylinder 320. The bottom end of the guide tube 330 is connected to the bullet feeding cylinder 320.

[0031] In order to prevent the water in the test box 100 from flowing back into the bullet feeding tube 320 during the process of replacing the bullets, in one embodiment, the bullet feeding member further includes a sealing plate 350 and a driving member, a sealing slot 312 located above the loading port 211 is provided on the side wall of the gun barrel 210, and the driving member is installed on the inner wall of the test box 100, and the output end of the driving member is connected to the sealing plate 350, and is used to drive the sealing plate 350 to insert or remove the sealing slot 312. The driving member can be implemented by a structure such as a cylinder.

[0032] At the same time, in one embodiment, the barrel 210 is located below the loading port 211 and is provided with a first sealing ring 213 and a second sealing ring 214 in sequence, and the barrel 210 is located above the loading port 211 and is provided with a third sealing ring 215 in sequence. The second sealing ring 214 and the third sealing ring 215 can prevent water from flowing into the feeding tube 320 from the gap between the barrel 210 and the changing sleeve 310 at both ends. At the same time, the first sealing ring 213 can prevent water from flowing into the feeding tube 320 from the loading port 31.

[0033] In order to facilitate the push rod 340 to drive the bullet to move along the length direction of the feed tube 320, in one embodiment, the feed tube 320 is arranged to be inclined upward in the direction close to the loading port 211, and the cross-section of the feed tube 320 is a square frame structure. The bottom of the bullet slides against the inner bottom wall of the square frame structure, and the two sides of the bullet slide against the inner bottom walls on both sides of the square frame structure.

[0034] By tilting the feed tube 320 , the push rod 340 pushes the bullet, and the bullet lies obliquely on the push rod 340 . At the same time, the shape of the feed tube 320 can ensure that the bullet passes through the loading port 211 in a facing posture and falls into the barrel 210 .

[0035] Among them, a sealing ring is installed on the outer wall of the push rod 340 at one end of the bullet feeding tube 320.

[0036] It should be noted that the top of the guide tube 330 should be higher than the water level in the test box 100 to avoid improper operation and water in the test box 100 flowing back and overflowing from the top of the guide tube 330 .

[0037] This embodiment also includes a camera assembly 400, which is installed in the test box 100. The camera assembly 400 is used to shoot the process of the bullet hitting the ice plate M, the ice crack expansion process and damage mode, the movement posture and ballistic trajectory of the projectile, so as to achieve the purpose of studying the efficient ice breaking of the projectile. It is understandable that the camera assembly 400 can be implemented by using multiple high-definition cameras.

The positioning assembly 600 has a positioning end for abutting against the ice plate M so that the center of the ice plate M is set vertically opposite to the gun barrel 210.

[0040] It is understandable that the positioning component 600 can select four positioning plates arranged around the test box 100, and the distance between the four positioning plates and the corresponding side walls of the test box 100 can be adjusted. The four positioning plates are respectively abutted against the four sides of the ice plate M, thereby limiting the position of the ice plate M.

[0041] Compared with the prior art: when the projectile launching assembly 200 moves relative to the cartridge changing sleeve 310 to the position where the loading port 211 is connected to the bullet feed port 311, the bullet can be delivered into the projectile launching assembly 200 outside the test box 100 through the bullet feeding piece; when the projectile launching assembly 200 moves relative to the cartridge changing sleeve 310 to the position where the loading port 211 is closed, the projectile launching assembly 200 can fire the bullet introduced through the loading port, and the entire test device can perform bullet changing operations from outside the test box 100, without going into the water and is not affected by the water depth, and is easy to operate.
