DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0032] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] Example 1 In order to make the technical solution of the embodiment of the present application clearer and easier to understand, the application background of the embodiment of the present application is introduced below.

[0034] With the development of military science and technology, various extremely powerful and lethal ammunition are constantly emerging. In order to meet the defense requirements of important strategic value targets, the corresponding defense capabilities are also constantly improving, and various weapons and equipment, combat personnel's protective equipment are also constantly upgrading. In the development history of protective equipment, various protective materials and structures emerge in an endless stream, and new advanced composite materials with high protection capabilities are also increasingly used in various defense systems. Therefore, it is of great significance to study protective materials with high protection capabilities.

[0035] With the development of weapon testing technology, experimental research on the impact resistance and penetration resistance of various protective materials has become an increasingly important part of the protection research process. In the protective performance test of protective materials, it is necessary to empower and accelerate the projectile so that it has a higher barrel exit velocity to penetrate the protective and test materials, observe the effects after penetration such as the residual velocity of the projectile, the deformation of the projectile, the damage and deformation of the protective and test materials, and then study the penetration and destructive ability of the projectile or the protective ability of the protective and test materials.

[0036] In the above protective material testing process, traditional ammunition technology is currently mainly used. However, using traditional ammunition technology to launch projectiles to test the penetration and destruction capabilities of projectiles or the protective capabilities of test materials has the following problems: (1) High experimental cost: Experimenting with traditional ammunition technology requires purchasing and manufacturing ammunition and ensuring its safe storage and use, which increases the cost of the experiment. (2) Limited experimental environment: Since the test uses actual ammunition, it needs to be carried out at a specific shooting range or test site. Due to the limitations of site and safety requirements, it is not convenient to conduct large-scale tests.

[0037] (3) Poor experimental repeatability: Each test requires reloading and ignition, so it is difficult to ensure that the conditions of each test are completely consistent, and the repeatability of the experimental results is poor.

[0038] In view of this, the embodiment of the present application is a device that uses carbon dioxide gas as a working fluid to realize projectile launch through high-speed injection. In particular, for the key project protection capability test, a large-caliber overload carbon dioxide launch device that can meet the launch of large projectiles (large size and high weight) is proposed. For details, please refer to Figure 1 The structural schematic diagram of a large-caliber overload carbon dioxide emission device provided in this embodiment shown includes: The barrel assembly 1 has a projectile placement space, and the projectile placement space is used to accommodate the projectile to be launched; The initial volume chamber assembly 2 is connected to the barrel assembly 1 and communicated with the projectile placement space; the initial volume chamber assembly 2 includes: a fracturing device outer tube 21 and a plurality of CO arranged inside the fracturing device outer tube 21. 2 The fracturing device 22, the primary chamber assembly 2 is used to release carbon dioxide gas; The buffer assembly 3 has a mounting space for the primary chamber assembly 2 formed in the middle of the buffer assembly 3; the buffer assembly 3 includes a plurality of groups of buffer parts that cooperate with each other, and each buffer part is sleeved on the outside of the fracturing device outer tube 21, and is used to absorb the recoil force generated when the primary chamber assembly 2 releases carbon dioxide to push the projectile to be launched.

[0039] In the embodiment of the present application, the projectile placement space in the barrel assembly 1 is used to place the projectile to be launched. The projectile placement space corresponds to the specifications of the required projectile in the initial design stage. In the present embodiment, it needs to correspond to a projectile of larger specifications, so the caliber can reach 200 mm, and there is no special limitation on the specific details. The initial volume chamber assembly 2 is connected to the internal space of the barrel assembly 1. The initial volume chamber assembly 2 includes a fracturing device outer cylinder 21 and a plurality of CO arranged inside the fracturing device outer cylinder 21. 2 The fracturing device 22 and the outer tube 21 of the fracturing device are used to place CO 2 Fracturator 22, and CO 2 The fracturator 22 can release carbon dioxide at a high speed to form a high-speed carbon dioxide gas flow, and then launch the projectile; wherein, the use of carbon dioxide gas as a propellant has a higher specific impulse and lower combustion products, which can not only improve the launch efficiency, but also has less pollution to the environment.

[0040] See also Figure 2 In a preferred embodiment, the barrel assembly 1 comprises: The barrel body 11; the barrel body 11 is connected to the initial volume chamber assembly 2 through the barrel mounting seat 12; the barrel body 11 forms a projectile placement space inside; An auxiliary support assembly is also provided outside the barrel body 11 , and the auxiliary support assembly is used to support the barrel body 11 .

[0041] Specifically, a projectile placement space is formed inside the barrel body 11 for accommodating the projectile; the barrel body 11 is fixedly welded to the barrel mounting seat 12, and then connected to the fracturing device outer tube 21, so that the CO 2 The high-speed carbon dioxide gas flow generated by the fracturing device 22 can flow into the barrel body 11 to launch the projectile to a designated position. Since the barrel body 11 needs to support the projectile and the barrel body 11 itself is relatively long, in order to better provide a more stable projectile placement space, an auxiliary support component is also provided on the outside of the barrel body 11.

[0042] See also Figure 2 In a preferred embodiment, the auxiliary support assembly includes: a plurality of sets of barrel clamps 13 and barrel support frames 14 that cooperate with each other; after the barrel clamps 13 and the barrel support frames 14 are connected, they are sleeved on the outside of the barrel body 11; The auxiliary branch pipe support seat 16 and the auxiliary branch pipe clamp 17 cooperate with each other, and the bottom of the barrel mounting seat 12 is connected to the auxiliary branch pipe support seat 16; The barrel support frame 14 and the auxiliary branch pipe support seat 16 are located on the same side of the barrel body 11 , and are jointly sleeved with at least two auxiliary branch pipes 18 arranged parallel to each other along a first direction, and are fixed to the auxiliary branch pipe support seat 16 by auxiliary branch pipe clamps 17 .

[0043] Specifically, in the embodiment of the present application, there are two groups of barrel clamps 13 and barrel support frames 14, which can be used as primary and secondary barrel support parts respectively; the barrel clamp 13 is fixed to the top of the barrel body 11, and the barrel support frame 14 is fixed to the barrel clamp 13 by bolts, so that the barrel clamp 13 and the barrel support frame 14 are tightly held outside the barrel body 11.

[0044] In addition, a group of auxiliary branch pipe support seats 16 and auxiliary branch pipe clamps 17 are also provided on the outside of the barrel mounting seat 12, which are used to strengthen the stable connection between the barrel body 11 and the initial volume chamber assembly 2; at the same time, the barrel support frame 14 and the auxiliary branch pipe support seat 16 each have two mounting holes, which can be jointly connected with at least two auxiliary branch pipes 18 arranged parallel to each other along a first direction, and then the auxiliary branch pipes 18 are used to stabilize the barrel body 11; the first direction here is the extension direction of the barrel body 11.

[0045] See also Figure 3-Figure 7 In a preferred embodiment, the initial chamber assembly 2 includes: The primary volume chamber body 23 is connected to the barrel mounting seat 12, and a first through hole 231 is opened in the middle of the primary volume chamber body 23, and the first through hole 231 is connected to the barrel body 11; The fracturing device channel flange 24 has one end connected to the side of the primary chamber body 23 away from the barrel mounting seat 12, and the other end connected to the fracturing device outer tube 21; the fracturing device channel flange 24 has a plurality of release channels 241 inside, and is connected to the CO2 The cracking device 22 is set accordingly; The middle part of the fracturing device channel flange 24 has a second notch, and the side wall and the bottom of the second notch are evenly distributed with a plurality of launch ports 242, and each launch port 242 is connected to at least one release channel 241; the second notch is arranged corresponding to the first through hole 231; The fracturing device mounting seat 25 is arranged in the fracturing device outer tube 21 and is used for mounting a plurality of CO2 fracturing devices 22 .

[0046] Specifically, the primary chamber body 23 is fixedly connected to the barrel mounting seat 12 , and the first through hole 231 in the middle thereof is communicated with the projectile placement space inside the barrel body 11 , which can ensure that the released carbon dioxide flows into the barrel body 11 .

[0047] The fracturing device channel flange 24 is used to transmit the carbon dioxide gas flow and is also used to connect the primary chamber body 23 and other CO 2 The fracturing device 22 is connected to the fracturing device, and the fracturing device channel flange 24 has a plurality of release channels 241 inside, and each release channel 241 is connected to a CO 2 The fracturing device 22 is arranged accordingly.

[0048] In addition, a second notch is provided in the middle of the fracturing channel flange 24, and a launch port 242 can be provided on the side wall and the bottom of the second notch. Since the second notch is located in the middle of the fracturing channel flange 24, the release channel 241 far from the second notch can release carbon dioxide at the corresponding launch port 242 by communicating with other release channels 241. Such a design can meet the requirements of arranging multiple CO 2 The requirement of the fracturing device 22 can ensure the flow direction and flow rate of carbon dioxide by gathering carbon dioxide gas at the second slot, thereby accelerating the launching efficiency and stability of the projectile.

[0049] See also Figure 4 In a preferred embodiment, the first through hole 231 has a first connecting section 2311 and a second connecting section 2312, the first connecting section 2311 is connected to the barrel body 11; the second connecting section 2312 is connected to the second slot; the aperture of the second connecting section 2312 gradually increases in the direction away from the first connecting section 2311, and the aperture of the first connecting section 2311 matches the aperture of the second connecting section 2312 close to the first connecting section 2311.

[0050] Specifically, the first through hole 231 has a first connecting section 2311 and a second connecting section 2312, and the first connecting section 2311 and the second connecting section 2312 have different apertures. The first connecting section 2311 can ensure that the carbon dioxide gas flow flows into the barrel body 11 stably and quickly, while the second connecting section 2312 is used to stably further contract the carbon dioxide gas flow released from the fracturing device channel flange 24, thereby increasing its flow rate and transferring it to the first connecting section 2311, and then entering the barrel body 11.

[0051] See also Figure 8 and Fig. 9 In a preferred embodiment, the buffer assembly 3 includes: a buffer protection cover 31; a plurality of buffer parts are arranged in the buffer protection cover 31; a pre-tightening baffle 32 is arranged at the port of the buffer protection cover 31 close to the fracturing device channel flange 24; the pre-tightening baffle 32 has a first extension section extending toward the port of the buffer protection cover 31; A force transmission baffle 33 in contact with the first extension section is disposed on the inner side thereof; the force transmission baffle 33 is located inside the buffer protection cover 31 and sleeved outside the outer tube 21 of the fracturing device; the side of the force transmission baffle 33 in contact with the first extension section is also in contact with a side of the fracturing device channel flange 24 close to the buffer protection cover 31; The buffer force bearing seat 34 is arranged at the end of the buffer protection cover 31 away from the fracturing device channel flange 24, and the buffer force bearing seat 34 has a second extension section extending toward the end of the buffer protection cover 31; a plurality of groups of mutually cooperating buffer parts are arranged between the second extension section and the force transmission baffle 33.

[0052] Specifically, the buffer protection cover 31 is used to install the initial volume chamber assembly 2, which can suppress the recoil force generated when the projectile is fired; wherein, a pre-tightening baffle 32 is provided at the port of the buffer protection cover 31 close to the fracturing device channel flange 24, and the pre-tightening baffle 32 has a first extension section extending toward the port of the buffer protection cover 31, which can provide a certain pre-tightening force for the buffer part inside the buffer protection cover 31 to ensure its stable installation.

[0053] Furthermore, a force transmission baffle 33 in contact with the first extension section is provided on the inner side thereof. Since the side of the force transmission baffle 33 in contact with the first extension section is also in contact with the side of the fracturing channel flange 24 close to the buffer protection cover 31, the recoil force generated when the fracturing channel flange 24 releases carbon dioxide to push the projectile to be launched will act on the force transmission baffle 33; in addition, a buffer force bearing seat 34 is also provided at the port of the buffer protection cover 31 away from the fracturing channel flange 24. The buffer force bearing seat 34 has a second extension section extending toward the port of the buffer protection cover 31, and a plurality of buffer parts are arranged between the force transmission baffle 33 and the second extension section. Therefore, after the recoil force acts on the force transmission baffle 33, the force transmission baffle 33 will be forced to move in a direction away from the primary chamber body 23, and then act on the buffer part in contact with it, so that the recoil force can be absorbed by the buffer part.

[0054] See also Figure 8-Figure 12 In a preferred embodiment, the buffer portion comprises: A nitrogen spring mounting seat 35, which is sleeved on the outside of the fracturing device outer tube 21 and has a plurality of nitrogen spring mounting positions arranged on the upper ring; Nitrogen springs 36, the nitrogen springs 36 are arranged one by one on the nitrogen spring installation position; An adjusting pad 37, which is sleeved on the outside of the nitrogen spring 36 and is located on the side of the nitrogen spring mounting seat 35 close to the force transmission baffle 33; the adjusting pad 37 is provided with a second through hole 371 corresponding to each nitrogen spring 36, and the nitrogen spring 36 extends through the second through hole 371 and contacts the nitrogen spring mounting seat 35 of the previous buffer portion; The nitrogen spring 36 in the buffer portion close to the force transmission baffle 33 contacts the side of the force transmission baffle 33 away from the preload baffle 32; the nitrogen spring mounting seat 35 in the buffer portion close to the buffer bearing seat 34 contacts the second extension section.

[0055] Specifically, the buffer parts are arranged inside the buffer protection cover 31, and their structures respectively include a nitrogen spring mounting seat 35, a nitrogen spring 36 and an adjusting pad 37; and because the nitrogen spring 36 will extend through the second through hole 371 and then contact the side of the force transmission baffle 33 away from the preload baffle 32, when the force transmission baffle 33 is moved by the recoil force, the nitrogen spring 36 in contact with it will be compressed first, and at the same time, the nitrogen spring 36 will be subjected to force, which will also drive the nitrogen spring mounting seat 35 and the adjusting pad 37 to continue to move backward; since the buffer parts include multiple groups, and each buffer part is in contact with the nitrogen spring mounting seat 35 in the previous buffer part, the recoil force can be absorbed step by step.

[0056] Furthermore, in one group of buffer parts, the bottom end surface of the nitrogen spring mounting seat 35 is parallel to the upper end surface of the adjustment pad 37; and the lengths of the nitrogen springs 36 extending through the second through holes 371 in different buffer parts are equal.

[0057] It should be noted that since the shape of the nitrogen spring 36 is mainly maintained by the nitrogen spring mounting seat 35 and the adjustment pad 37, and the contraction of the nitrogen spring 36 will also drive the two to move in the buffer protection cover 31, it is necessary to ensure that each nitrogen spring 36 is in contact with the end face of the previous nitrogen spring mounting seat 35, and whether the length of the nitrogen spring 36 extending through the second through hole 371 is equal, so as to prevent the buffer part from getting stuck during the movement, and at the same time, it can also provide a better buffering effect for the entire launching device.

[0058] See also Fig.13 In a preferred embodiment, the launch device further comprises: a gun carriage assembly 4; the gun carriage assembly 4 comprises: A gun support fixing seat 41, on which a load bearing shaft 43 and an angle adjustment rod 44 are provided; The load-bearing shaft 43 is movably connected to the mounting portion 341 outside the buffer load-bearing seat 34 , and the angle adjustment rod 44 is movably connected to the outside of the buffer protection cover 31 through the joint shaft 42 .

[0059] Specifically, the launching device can adjust the position and orientation of the barrel body 11 through the gun mount assembly 4, so that the projectile can be installed at a set angle and launched to a designated position to complete the test; wherein, the gun support fixing seat 41 serves as the main frame of the gun mount assembly 4, and the load-bearing shaft 43 arranged thereon is movably connected with the mounting portion 341 outside the buffer load-bearing seat 34, ensuring that the buffer protection cover 31 has a swing fulcrum; the angle adjustment rod 44 is hinged to the buffer protection cover 31 through the joint shaft 42, so that the buffer protection cover 31 can be lifted upward by a certain angle, thereby driving the assembled barrel assembly 1 and the initial volume chamber assembly 2 to be lifted by the same angle, and the projectile in the barrel body 1 can be launched to a designated position according to the angle.

[0060] Based on the above description, it can be seen that the present application proposes a large-caliber overload carbon dioxide emission device, and its specific working principle is as follows: First, after the barrel assembly 1, the initial volume chamber assembly 2 and the buffer assembly 3 are assembled in sequence, the projectile is placed in the barrel body 11, and then the firing angle of the barrel body 11 is adjusted by the gun mount assembly 4.

[0061] After adjusting to the corresponding angle, multiple CO 2The fracturator point is electrically ignited to generate high-pressure and high-speed carbon dioxide gas, which is compressed at the fracturator channel flange 24 and the primary chamber body 23, so that it can quickly flow into the barrel body 11, pushing the projectile to the designated position; during the process, due to the excessive impact force of the launch, the primary chamber assembly 2 will be driven to move backward. At this time, the fracturator channel flange 24 transmits the recoil force to the force transmission baffle 33, and the force transmission baffle 33 compresses the nitrogen spring 36, and drives the nitrogen spring mounting seat 35 and the adjustment pad 37 thereon to continue to move backward. Since the rear end surface of the nitrogen spring mounting seat 35 is also in contact with the top end surface of the nitrogen spring 36 of the next buffer part, the recoil force will be absorbed step by step by the multiple buffer parts inside the buffer assembly 3, ensuring the safety and stability of the projectile launch.
