DETAILED DESCRIPTION

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0019] like Figure 1 As shown, a projectile penetration and icebreaking test device provided by the present invention includes a frame 100, a projectile launching assembly 200, a positioning fixture 300, a protection assembly 400 and an image shooting assembly 500. The frame 100 has a horizontal test surface for placing a sample, and an opening 121 located below the sample is formed on the horizontal test surface. The bottom of the projectile launching assembly 200 is a launching end arranged to point to the horizontal test surface. The projectile launching assembly 200 is rotatably connected to the frame 100 in a vertical plane, and the rotation of the projectile launching assembly 200 is used to adjust the inclination angle of the launching end. The positioning fixture 300 is installed on the horizontal test surface of the frame 100, and the positioning fixture 300 has a positioning end for fixing the sample. The protection assembly 400 is arranged below the horizontal test surface and fixedly connected to the frame 100. The image shooting assembly 500 is installed on the frame 100, and the image shooting assembly 500 has an image acquisition end arranged facing the sample.

[0020] During implementation, the sample can be fixed on the horizontal test surface of the frame 100 by the positioning fixture 300, and the inclination angle of the launch end of the projectile launch component 200 can be adjusted by rotating it, and the image information of the sample can be collected by the image shooting component 500, so as to study the impact damage of the projectile on the sample at different penetration angles. There is no need to adjust the inclination angle of the sample and the image shooting component 500, and the test steps are simple and easy to operate.

[0021] The frame 100 in this embodiment is a structure that carries the missile launching assembly 200, the positioning fixture 300, the protection assembly 400 and the image capturing assembly 500. It can be formed by splicing a plurality of connecting beams. It is a structure that can be thought of by those skilled in the art and will not be elaborated and illustrated in detail here.

[0022] In order to increase the movable range of the projectile launching assembly 200 relative to the sample, in one embodiment, the device also includes a horizontally arranged beam 110 parallel to the rotation plane of the projectile launching assembly 200, and both ends of the beam 110 are fixedly connected to the frame 100, and the projectile launching assembly 200 is rotatably and slidably connected to the beam 110.

[0023] In one embodiment, the device further includes a support plate 120 fixedly connected to the frame 100 and arranged horizontally, and an opening 121 is formed at the center of the support plate 120, and the opening 121 is smaller than the sample setting. Among them, the support plate 120 can be made of an acrylic plate, which can ensure light transmittance and has better impact resistance than materials such as fiberglass.

[0024] The projectile launching assembly 200 in this embodiment is used to launch a bullet 220 and shoot a sample. The sample in this embodiment is an ice plate, so as to study the impact damage degree of the projectile on the ice plate.

[0025] In one embodiment, the projectile launching assembly 200 includes a barrel 210, a bullet 220, a rotating block 230 and a compressed air source 240. The interior of the barrel 210 is formed with a gun chamber for launching the bullet 220. The bottom end of the barrel 210 is a launching end, and the top end of the barrel 210 is connected to the air outlet end of the compressed air source 240. The barrel 210 is fixedly connected to the rotating block 230, and the rotating block 230 is rotatably connected to the frame 100 in a vertical horizontal plane.

[0026] Among them, a loading port 211 is opened on the side wall of the gun barrel 210, and an elastic member 212 for elastically fixing the bullet 220 is arranged inside the gun barrel 210 and below the loading port 211. The projectile launching assembly 200 also includes a sealing sleeve 213 which is sleeved on the gun barrel 210 and is slidably and sealedly connected to the gun barrel 210. The sealing sleeve 213 can slide to a position to close the loading port 211. An exhaust port 214 is opened on the side wall of the gun barrel 210 and below the elastic member 212. The gun barrel 210 is arranged through a first through hole 231 opened on the rotating block 230.

[0027] After the bullet 220 is loaded into the loading port 211, the bullet 220 moves to the position where it is engaged with the elastic member 212 under its own weight. The compressed air source 240 is used to connect the high-pressure air source to the barrel 210. Under the elastic deformation of the elastic member 212, the bullet 220 can be accelerated to be ejected from the barrel 210. The exhaust port 214 is located on both sides of the end area of ​​the barrel 210, and is used to discharge the gas accompanying the ejection of the bullet body as much as possible, thereby reducing the impact of the high-pressure airflow on the damage to the ice plate.

[0028] The compressed air source 240 includes an air pressure tank, a connecting pipe, a valve and an air compressor. The top of the gun barrel 210, the air pressure tank, the connecting pipe and the air compressor are connected in sequence. The valve is installed on the connecting pipe. The high-pressure gas is transported to the air pressure tank through the air compressor, and then transported to the gun barrel 210 after buffering and pressure regulation of the air pressure tank, thereby providing power for the firing of the bullet 220.

[0029] like Figure 2-3 As shown, in one embodiment, the projectile launching assembly 200 further includes a slider 250 slidably connected to the frame 100 along a horizontal direction parallel to the rotation plane of the barrel 210, and the rotating block 230 is rotatably connected to the frame 100 via the slider 250, wherein the barrel 210 is arranged through a first through hole 231 opened on the rotating block 230.

[0030] In order to facilitate the control of the rotation angle of the rotating block 230, the projectile launching assembly 200 further includes a protractor 232 and a protractor pin 233. The protractor 232 is fixedly connected to the side of the slider 250 close to the rotating block 230. The projection of the center point of the protractor 232 on the rotating block 230 overlaps with the rotation center of the rotating block 230. The protractor pin 233 is fixedly connected to the side of the rotating block 230 close to the slider 250. The protractor pin 233 is arranged perpendicular to the rotation direction of the rotating block 230. At the same time, in order to facilitate the rotation of the rotating block 230, the handle 234 can be fixed to the rotating block 230 by screws.

[0031] It can be understood that a sliding groove 251 is provided on the rotating block 230 for sliding connection with the beam 110, and a rotating shaft 235 is fixedly connected to the rotating block 230, and the rotating shaft 235 is inserted into the second through hole 252 provided on the slider 250, thereby realizing the rotation and sliding function of the rotating block 230 relative to the frame 100.

[0032] To facilitate locking the rotating block 230 to rotate to the current angle, in one embodiment, a plurality of hemispherical grooves 236 are provided on the side of the rotating block 230 close to the slider 250, and the plurality of hemispherical grooves 236 are arranged circumferentially along the rotating shaft 235. A positioning spring 253, a gasket 254 and a steel ball 255 are sequentially connected to the side of the slider 250 close to the rotating block 230, wherein the steel ball 255 is clamped with any hemispherical groove 236. By setting the distance between the plurality of hemispherical grooves 236, the angle of each rotation of the rotating block 230 can be limited.

[0033] In this embodiment, the angle between two adjacent hemispherical grooves 236 is 5°, and 13 hemispherical grooves are prefabricated, and the adjustment range thereof is -30° to +30°.

[0034] The positioning fixture 300 in this embodiment is a structure for fixing the sample (ie, the ice plate) to the support plate 120 of the rack 100 .

[0035] In one embodiment, the positioning fixture 300 includes an X-axis fixing member 310, a Y-axis fixing member 320 and a Z-axis fixing member 330 installed on the horizontal test surface of the frame 100, the X-axis fixing member 310 is configured to fix both sides of the sample along the horizontal X-axis direction, the Y-axis fixing member 320 is configured to fix both sides of the sample along the horizontal Y-axis direction, and the Z-axis fixing member 330 is configured to fix the top of the sample along the vertical Z-axis direction.

[0036] Among them, the X-direction fixing member 310 and the Y-direction fixing member 320 each include two clamping plates arranged opposite to each other, and the two clamping plates are slidably connected to the frame 100 in opposite or opposite directions, and the opposite sides of the two clamping plates are used to fix the two sides of the sample. The two sides of the sample can be fixed by the relative movement of the clamping plates, and the sample can be released by the opposite movement of the clamping plates. It should be noted that the above-mentioned X-direction and Y-direction refer to the movement of the corresponding clamping plates along the horizontal X-axis direction and the horizontal Y-axis direction, wherein the horizontal X-axis direction and the horizontal Y-axis direction are arranged perpendicular to each other.

[0037] like Figure 4 As shown, the Z-direction fixing member 330 includes a frame-shaped pressing plate 331, a pressing screw 332, a pressing block 333 and a compression spring 334. The frame-shaped pressing plate 331 is arranged above the horizontal test surface. The internal cavity of the frame-shaped pressing plate 331 is smaller than the sample and is arranged opposite to the opening 121. The free end of the pressing screw 332 passes through the pressing block 333 and the compression spring 334 downward in sequence and is threadedly connected to the frame 100. The bottom of the pressing block 333 abuts against the top of the side wall of the frame-shaped pressing plate 331. By rotating the pressing screw 332, the pressing block 333 can be driven to move downward, so that the sample is fixed on the support plate 120 through the frame-shaped pressing plate 331. Since the ice plate has a low strength, the compression spring 334 can prevent the ice plate from being partially damaged during the clamping process.

[0038] It is understandable that the number of the pressing screw 332 , the pressing block 333 and the pressing spring 334 can be multiple and arranged in sequence along the circumference of the frame-shaped pressing plate 331 .

[0039] The protection assembly 400 in this embodiment is disposed below the horizontal test surface and fixedly connected to the frame 100 , and is used to receive the bullet 220 and absorb the remaining kinetic energy after the bullet 220 penetrates the sample.

[0040] In one embodiment, the protection assembly 400 includes a protection cylinder 410, a silicone pad 420 and a foam baffle 430. The protection cylinder 410 is fixedly connected to the frame 100 and is arranged below the horizontal test surface and facing the opening 121. The silicone pad 420 is laid on the inner bottom wall of the protection cylinder 410, and the foam baffle 430 is arranged on the inner side wall of the protection cylinder 410. There are two foam baffles 430, which are arranged in sequence along the traveling direction of the bullet 220 and are located on the inner walls on both sides of the protection cylinder 410.

[0041] The protective cylinder 410 can be made of acrylic material, which can ensure light transmittance and have better impact resistance than glass fiber reinforced plastics. The silicone pad 420 can better absorb the remaining kinetic energy of the projectile after penetrating the ice plate. The foam baffle 430 is used to prevent the projectile from directly hitting the two sides of the protective cylinder 410 after ricocheting.

[0042] In this embodiment, the image capturing component 500 is mounted on the frame 100 and has an image collecting end arranged facing the sample.

[0043] In one embodiment, the image capture component 500 includes at least two cameras 510 connected to the frame 100, at least one of the cameras 510 is arranged above the sample and its image acquisition end is configured to collect image information of the top of the sample, and at least another camera 510 is arranged around the sample and its image acquisition end is configured to collect image information of the side of the sample.

[0044] In this embodiment, the number of cameras 510 is two, and a switch can be configured to control the operation / stop of the camera 510. The switch can be electrically connected to the two cameras 510 via a three-way connector to achieve the linkage of the two cameras 510, and can be illuminated by an LED light 520.

[0045] In this embodiment, the device further includes a laser level 600 and a laser pen installed on the frame 100 .

[0046] Among them, the laser level 600 is used to determine the center position of the fixed ice plate. Specifically, after adjusting the angle of the barrel 210, before the projectile is installed, the laser pen will be placed just at the exhaust port 214 position, and by adjusting the position of the slider 250, the laser point where the laser pen reaches the ice plate is coincident with the cross point where the laser level 600 hits the surface of the ice plate, so that the initial position of the projectile head penetrating the surface of the ice plate is located at its center.

[0047] Workflow: 1) Place the prepared ice plate on the upper part of the support plate 120, quickly position the ice plate to the center of the support plate 120 by adjusting the positions of the four clamping plates, place the frame-shaped pressing plate 331 directly above the ice plate, adjust the position of the clamping pressing block 333, and fix it by pressing the screw 332; 2) Rotate the handle 234 to drive the gun barrel 210 to rotate, and adjust the angle of the protractor needle 233 pointing to the protractor 232 to the projectile penetration angle required for the test; 3) Turn on the laser level 600, point the intersection of the cross-shaped laser line to the center of the ice plate, hold the laser pen inside the exhaust port 214, turn on the laser pen, and adjust the horizontal position of the slider 250 until the laser point generated by the laser pen coincides with the cross-shaped laser line generated by the laser level 600; 4) Remove the laser pen, turn on the camera 510 and the LED light 520, and adjust the camera 510 to a suitable position through the real-time image; 5) Install the projectile in the loading port 211, move the sealing slide bar to close the loading port 211, use the air compressor to pressurize the air pressure tank, adjust the pressure to a fixed air pressure through the pressure gauge, and when the test is ready, press the valve and switch at the same time; 6) After the image data is stored, a set of tests is completed; then the crushed ice is cleaned, the bullet 220 dropped into the protective cylinder 410 is taken out, a new ice plate is clamped again, and the above operation is repeated until all impact tests are completed.

[0048] Compared with existing technologies: 1) The present invention discloses a projectile penetration and icebreaking test device. Compared with the traditional one-stage or two-stage light gas gun device, the device adopts a top-down firing method, occupies a small space, has a low cost, and is easy to move; 2) Compared with adjusting and fixing the angle of a larger ice plate, the present invention can directly realize the precise setting of any penetration angle of the projectile by using the rotating mechanism of the barrel 210. The device is simple and easy to operate, and there is no need to repeatedly adjust the position of the high-speed camera 510, thus saving the repetitive test cycle; 3) By using the laser level 600 and placing a laser pen in the exhaust port 214, the center position of the projectile head impacting the ice plate can be quickly adjusted, thereby improving the impact test efficiency.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
