Description

Technical Field

[0001] The invention belongs to the technical field of underwater penetration test of shaped charge, and particularly relates to an underwater penetration performance test device for shaped charge. Background Art

[0002] Shaped charges can be divided into three types according to the different shaped penetrators, namely shaped jet (JET), rod jet (JPC) and explosively formed projectile (EFP). The three significant common characteristics are that the impact velocity of the projectile on the target is large. Generally speaking, the head velocity of the traditional shaped jet can reach 8000 - 10000 m / s, the head velocity of the rod jet can reach 3000 - 6000 m / s, and the velocity of the explosively formed projectile can reach 1500 - 3000 m / s. However, as the penetration depth of the projectile increases, the velocity of the projectile continuously decays, and the deformation and erosion degree of the projectile during penetration become smaller and smaller. In this stage, the interaction mode between the projectile and the target will also change, and the relative strength between the projectile and the target cannot be ignored anymore.

[0003] At present, there are chemically reactive targets in some shallow waters. Chemically reactive targets in shallow waters are more likely to explode accidentally due to human activities. These chemically reactive targets have caused serious impacts on shipping lanes, port construction, fishery fishing, etc. Usually, these chemically reactive targets can be destroyed by salvage and underwater detonation methods. However, salvage has potential safety hazards, and underwater detonation includes two methods: sympathetic detonation destruction and shaped charge penetration destruction.

[0004] Since shaped charges have good penetration performance, therefore, using the shaped charge structure to blast and damage chemically reactive targets existing in shallow waters has good prospects. However, how to verify which shaped charge structure in the explosively formed projectile (EFP) and the rod jet (JPC) is more suitable for destroying chemically reactive targets at different water depths is an urgent problem to be solved. Especially how to verify the underwater forming law of the two shaped charges and the influence of the water layer on the underwater penetration performance of the two shaped charges, which is crucial for subsequent selection of which shaped charge structure and reasonable arrangement of parameters to achieve the damage of chemically reactive targets. Summary of the Invention

[0005] The purpose of the invention is to overcome the deficiencies in the prior art and provide an underwater penetration performance test device for shaped charge, which can detect the velocity of the jet at different positions, facilitate the adjustment of appropriate standoff distance and water depth, and verify the target damage effect of different charge structures at different water depths.

Detailed implementation mode

[0018] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and cannot be used to limit the protection scope of the present invention.

[0019] Embodiment 1 This embodiment provides a shaped charge underwater penetration performance test device. As Figure 1 - Figure 2 shown, it includes: A transparent water bucket 10, used to hold water at a preset depth. In this embodiment, the transparent water bucket 10 is a cylindrical water bucket made of PP material or polyethylene material; A standoff adjustment frame 20, movably connected to the transparent water bucket 10. The distance between the standoff adjustment frame 20 and the top of the transparent water bucket 10 is adjustable and is above the water surface; A shaped charge structure 30, arranged on the top of the standoff adjustment frame 20; An arc-shaped target plate 50, arranged at the bottom of the transparent water bucket 10. By adjusting the position between the standoff adjustment frame 20 and the transparent water bucket 10, the distance between the shaped charge structure 30 and the arc-shaped target plate 50 can be adjusted, that is, the standoff of the shaped charge structure 30. And by adjusting the water depth in the transparent water bucket 10, the depth of the arc-shaped target plate 50 in the water can be controlled; It also includes a first velocity detection target 41, a second velocity detection target 42, and a third velocity detection target 43 arranged in sequence from top to bottom. The first velocity detection target 41 is arranged on the water surface, the second velocity detection target 42 is arranged at the apex of the arc of the arc-shaped target plate 50, and the third velocity detection target 43 is arranged at the bottom of the transparent water bucket 10.

[0020] The shaped charge structure 30, the first velocity detection target 41, the second velocity detection target 42, the third velocity detection target 43, and the arc-shaped target plate 50 are all located on the axis of the transparent water bucket 10. The shaped charge structure 30 is used to shoot a metal jet at the arc-shaped target plate 50. The first velocity detection target 41 is used to detect the velocity of the metal jet before entering the water. The second velocity detection target 42 is used to detect the velocities of the metal jet before and after penetrating the arc-shaped target plate 50. The third velocity detection target 43 is used to detect the velocity of the metal jet when it reaches the bottom of the transparent water bucket 10. After the shaped charge structure 30 explodes, the generated metal jet sequentially passes through the first velocity detection target 41, the second velocity detection target 42, the arc-shaped target plate 50, and the third velocity detection target 43. The velocities of the metal jet at any point of the three detection targets can be detected by the first velocity detection target 41, the second velocity detection target 42, and the third velocity detection target 43. By judging the velocities at each point, the penetration ability of the metal jet can be obtained. When the velocity of the metal jet before penetrating the arc-shaped target plate 50 is higher than the velocity of the metal jet before entering the water, it indicates that the metal jet still has a relatively high kinetic energy, and the standoff distance can be appropriately increased. If the metal jet still maintains a certain velocity at the bottom of the water bucket 10, the water depth can be appropriately increased.

[0021] Further, the standoff distance adjustment frame 20 is connected to the top of the transparent water bucket 10 through a connection assembly 21; as Figure 3 shown, the connection assembly 21 includes a hook-shaped member 211 and a connecting member 212. The hook-shaped member 211 is connected to the top of the transparent water bucket 10. One end of the connecting member 212 is detachably connected to the hook-shaped member 211 to change the position on the surface of the connecting member and adjust the distance between the shaped charge structure 30 and the arc-shaped target plate 50, and the other end is connected to the standoff distance adjustment frame 20. In this embodiment, the hook-shaped member 211 can be hooked on the edge of the transparent water bucket 10. The hook-shaped member 211 is connected to the surface of the connecting member 212. By controlling the connection position between the hook-shaped member and the connecting member, the position of the standoff distance adjustment frame 20 from the edge of the transparent water bucket 10 can be controlled. In this embodiment, the connecting member can be a rod, a rope, or a strip-shaped member. When a rod-shaped member is selected, the standoff distance adjustment frame 20 can be higher or lower than the edge of the transparent water bucket 10, while when a rope or strip-shaped member is selected, the standoff distance adjustment frame 20 can only be adjusted to be lower than the edge of the transparent water bucket 10. The hook-shaped member and the rope or strip-shaped member are connected by tying, and the hook-shaped member and the rod are connected by a clamp.

[0022] Further, a first clamping assembly for clamping the first velocity detection target 41 and the second velocity detection target 42 is provided below the standoff distance adjustment frame 20. When the water depth changes or the position of the standoff distance adjustment frame 20 changes, the first velocity detection target 41 is required to be above the water surface. Therefore, the first velocity detection target 41 needs to be adjusted according to the position of the water surface, and clamping by the first clamping member is beneficial to adjusting the height position of the first velocity detection target 41.

[0023] Further, a post-effect target 52 is provided below the arc-shaped target plate 50. The post-effect target 52 includes a base and a retaining ring provided above the base. The retaining ring is located on the outer peripheral side of the arc-shaped target plate 50. A second clamping assembly for clamping the second velocity detection target 42 and the third velocity detection target 43 is provided on the upper end surface of the base.

[0024] Further, both the first clamping assembly and the second clamping assembly are provided directly below the shaped charge structure 30. The first clamping assembly and the second clamping assembly each include a number of fixing structures 71 that are symmetrically distributed about a center. A protrusion 72 is provided on the opposite side of the fixing structure 71. A card slot 73 for supporting the first velocity detection target 41, the second velocity detection target 42, or the third velocity detection target 43 is formed between adjacent protrusions 72 in the horizontal direction. As Figure 4 shown, in this embodiment, the first clamping and second clamping assemblies each include three fixing structures 71 that are symmetrically distributed about a center.

[0025] In this embodiment, the fixing structure 71 is an arc-shaped strip structure. The three fixing structures 71 are elastic by themselves. When adjusting the position of the first velocity detection target 41, manually control the first velocity detection target 41 to move along the length direction of the first clamping assembly. The first velocity detection target 41 can move between the respective card slots 73. When the first velocity detection target 41 is in a card slot 73 at a suitable position, stop moving and fix it in that position.

[0026] Further, the second velocity detection target 42 includes an outer detection target and an inner detection target. The outer detection target is clamped in the card slot 73 of the first clamping assembly. The outer detection target is provided above the arc-shaped target plate 50 for detecting the velocity of the metal jet before it reaches the arc-shaped target plate 50. The inner detection target is clamped in the card slot 73 of the second clamping assembly and is provided below the arc-shaped target plate 50 for detecting the velocity of the metal jet after it reaches the arc-shaped target plate 50. The velocity loss of the metal jet after passing through the arc-shaped target plate 50 can be judged by the outer detection target and the inner detection target.

[0027] Further, the first velocity detection target 41, the outer detection target, the inner detection target, and the third velocity detection target 43 each include a target body. The upper end surface of the target body is used as the front target surface, and the lower end surface is used as the rear target surface. Metal wires are provided on both the front target surface and the rear target surface in a serpentine distribution. The first velocity detection target 41, the outer detection target, the inner detection target, and the third velocity detection target 43 are all electrically connected to a data detection terminal through wires. After detonating the shaped charge structure 30, a metal jet is generated. When the metal jet passes through the front target surface or the rear target surface, the metal wires on the surface of the front target surface or the rear target surface are melted, and the electrical connection between the data detection terminal and the front target surface or the rear target surface is disconnected. By judging the time interval between the disconnection of the front and rear target surface circuits and the thickness of the target body, the velocity of the metal jet passing through the current velocity detection target can be calculated.

[0028] Further, a protective cover 11 is provided on the inner wall of the transparent water bucket 10, and the wire extends to the outside of the transparent water bucket 10 through the protective cover 11. In this embodiment, the protective cover 11 is an arc-shaped aluminum plate, and the aluminum plate is attached to the inner wall of the transparent water bucket 10, forming a cavity between the aluminum plate and the transparent water bucket. There are holes on the surface of the aluminum plate, and the wire can pass through the holes into the cavity through the aluminum plate. Such an arrangement can provide a certain protection for the wire to avoid being affected by the shock wave.

[0029] Further, a wall pressure sensor and a strain gauge 51 are provided at the apex of the arc-shaped target plate 50.

[0030] Embodiment 2 Based on Embodiment 1, this embodiment provides a test method for the underwater penetration performance of a shaped charge. The method includes the following steps: Step 1: Arrange the second velocity detection target 42, the third velocity detection target 43, and the arc-shaped target plate 50 in sequence at the bottom of the transparent water bucket 10. Introduce the wires of each velocity detection target into the protective cover 11 on the side wall of the transparent water bucket 10, and then lead them out of the transparent water bucket 10.

[0031] Step 2: Fill the transparent water bucket 10 with water and keep the water level at a preset position. Connect the first velocity detection target 41 below the height adjustment frame 20, introduce the wire into the protective cover 11 on the side wall of the transparent water bucket 10, and then lead it out of the transparent water bucket 10. Arrange the height adjustment frame 20 above the water surface and adjust its height so that the distance between the height adjustment frame 20 and the arc-shaped target plate 50 meets the preset height.

[0032] Step 3: Arrange the shaped charge structure 30 at the middle position of the height adjustment frame 20, and set up the detonation circuit and the signal circuits of the velocity detection targets, the wall pressure sensor, and the strain gauge 51.

[0033] Step 4: Set up a high-speed camera on one side of the transparent water bucket 10.

[0034] Step 5: Detonate the shaped charge structure 30, take pictures of the post-detonation picture through the high-speed camera, and detect the velocity of the metal jet at each position through each velocity detection target.

[0035] Among them, repeat steps 1 to 5 for multiple tests. For the subsequent test, adjust the height of the height adjustment frame 20 and the water level according to the detection results of each velocity detection target in the previous test, so that the damage effect of the arc-shaped target plate 50 in the subsequent test is better than that in the previous test.

[0036] In each test, two transparent water buckets 10 can be arranged simultaneously. An EFP shaped charge structure is arranged on one height adjustment frame 20, and a JPC shaped charge structure is arranged on the other height adjustment frame 20. After the preparatory work is adjusted, the EFP shaped charge structure and the JPC shaped charge structure are detonated simultaneously. The damage effect of the metal jet on the arc target plate 50 is recorded by each velocity detection target and a high-speed camera. The wall pressure sensor and the strain gauge 51 can measure the reflected overpressure of the shock wave formed by the EFP shaped charge or the JPC shaped charge structure on the target surface. By setting the jet velocity and the reflected overpressure, the damage effect of the EFP shaped charge or the JPC shaped charge structure on the arc target plate 50 can be comprehensively judged under various water depths and height-of-burst parameters.

[0037] As Figure 5 shown, when appropriate parameters are obtained in the test, a spacer 61 and a TNT charge 60 can be set below the arc target plate 50. If the detonation of the TNT charge 60 can be induced, it proves the reliability of the parameters obtained in the test.

[0038] Combined with the above embodiments, the present invention provides an observable test environment by setting a transparent water bucket structure. An appropriate water depth is set inside the transparent water bucket, an arc target plate is set at the bottom, and a height adjustment frame with an adjustable height is provided above. A shaped charge structure is arranged on the height adjustment frame. A plurality of velocity detection targets are arranged along the jet direction. After the shaped charge structure is detonated, the velocity of the jet at each position can be detected by each velocity detection target, which is beneficial for users to adjust the appropriate height of burst and water depth, and verify the damage effect of different charge structures on chemically reactive targets at different water depths.
