Description

Technical Field

[0001] The present invention relates to the technical field of solid propellants, in particular to a test device for analyzing the structural integrity of high-energy solid propellant charges. Background Art

[0002] During the development and testing of solid propellants, whether using pellet casting, pouring, or screw extrusion, the inner surface of the grain may contain defects such as tiny cracks, scratches, dents, or incomplete plasticization. These defects are not easily detected by conventional X-ray inspection, but they are important factors affecting the combustion performance of solid propellants. Currently, the internal surface performance testing of solid propellants is mainly completed using industrial endoscopes. When using endoscopes to perform performance testing on the inner surface of solid propellants, the operator needs to manually insert the endoscope into the inner hole of the solid propellant.

[0003] The shapes of the inner holes of existing solid propellants vary. When inspecting solid propellants with a six-tooth star-shaped inner hole cross-section, an endoscope is required to inspect each star hole tooth. Since the operation relies on manual labor, the endoscope is very likely to come into contact with the inner surface of the solid propellant, causing scratches on the inner surface of the solid propellant, resulting in test failure. In severe cases, the solid propellant may even be ignited, posing a threat to the safety of the operator. In addition, foreign matter may be attached to the inner hole of the solid propellant. These foreign matter will affect the operator's assessment of the structural integrity of the solid propellant charge, resulting in inaccurate assessment of the test results by the operator.

The inner sides of the circumferentially equidistant fixed clamps 105 are all provided with arc surfaces. The three connecting frames 102 are all fixed with a first limiting rod 106 facing the axis of the rotating disk 103. The first limiting rod 106 is limited and slidably matched with the adjacent fixed clamps 105. A spring for resetting the fixed clamp 105 is fixed between the fixed clamp 105 and the adjacent connecting frame 102. An electric roller 107 is provided on the inner side of the fixed clamp 105. There are four electric rollers 107 equidistantly distributed along the arc surface of the fixed clamp 105. The rotating disk 103 is provided with a support assembly for lifting the support plate 501. The support seat 101 is fixed with a support frame 201. The top of the support frame 201 is fixed with a first electric push rod 202. The telescopic end of an electric push rod 202 faces downward, and the middle part of the support frame 201 is slidably connected to a movable plate 203. The telescopic end of the first electric push rod 202 is fixed to the movable plate 203. The movable plate 203 is fixed with a fixed rod 204. The fixed rod 204 is fixed with a sleeve rod 205. The sleeve rod 205 is cylindrical, and the axis of the sleeve rod 205 coincides with the axis of the rotating disk 103. The bottom of the sleeve rod 205 is fixed with two symmetrically distributed guide sleeves 206. The two symmetrically distributed guide sleeves 206 are both L-shaped. The sleeve rod 205 is slidably connected to two symmetrically distributed endoscopes 207. The upper ends of the two symmetrically distributed endoscopes 207 are both made of hard materials. The L-shaped guide sleeves 206 guide the adjacent endoscopes 207 so that the lenses of the endoscopes 207 are in In the horizontal state, the endoscope 207 faces the inner hole surface of the solid propellant, so that the operator can observe the integrity of the inner hole structure of the solid propellant more comprehensively. The endoscope 207 passes through the sleeve rod 205 and the guide sleeve shell 206. The endoscope 207 is slidably connected to the sleeve rod 205 and the guide sleeve shell 206. The bottom of the two symmetrically distributed endoscopes 207 are fixed with a first movable rod 209. The bottom of the sleeve rod 205 is fixed with a fixed plate 210. The fixed plate 210 is located below the two symmetrically distributed endoscopes 207. The first movable rod 209 and the fixed plate 210 are limited and slidably matched. The fixed plate 210 supports the adjacent endoscopes 207 to prevent the endoscopes 207 from deviating and causing the endoscopes 207 to touch the inner hole of the solid propellant.Causes damage or combustion of solid propellant, thus creating a dangerous situation.

[0031] like Figure 5 and Figure 6 As shown, the fixing clamp 105 near the support frame 201 is fixed with the second movable rod 301, and the second movable rod 301 is set to be U-shaped, and the bottom of the movable plate 203 is slidably connected to the third movable plate 302, and the third movable plate 302 is slidably connected to the second movable rod 301, and the third movable plate 302 is provided with a through hole, and the upper side of the through hole is provided with an inclined surface, and the support frame 201 is slidably connected to the L-shaped plate 303, and the second limiting rod 304 is fixed to the bottom left side of the movable plate 203, and the second limiting rod 304 is slidably connected to the movable block 305, and the movable block 305 is fixed with a push rod 308, and the push rod 308 contacts the endoscope 207, and a spring for resetting the sleeve rod 205 is fixed between the second limiting rod 304 and the movable block 305, and the movable block 305 is fixedly connected to the L-shaped plate 303, and the right side of the movable block 305 is hinged with a rotating plate 306, and the rotating plate 306 and the third movable plate The inclined surface of the movable plate 302 is squeezed and fitted, and the L-shaped plate 303 is fixedly connected to the third electric push rod 307, which is located on the right side of the upper end surface of the L-shaped plate 303, and the telescopic end of the third electric push rod 307 is facing upward. The telescopic end of the third electric push rod 307 is slidingly connected to the rotating plate 306, and the telescopic end of the third electric push rod 307 drives the rotating plate 306 to rotate around its hinge axis, so that the angle between the rotating plate 306 and the L-shaped plate 303 changes, and then adjusts the extended length of the endoscope 207, so that this device is suitable for testing different types of solid propellants. The lower end of the movable block 305 is fixedly connected to the second electric push rod 208, and the telescopic end of the second electric push rod 208 is fixedly connected to the upper end of the endoscope 207. The telescopic end of the second electric push rod 208 adjusts the pop-up amount of the endoscope 207, so that the operator can more comprehensively observe the structural integrity of the inner hole of the solid propellant.

[0032] like Figure 6 、 Figure 8 and Figure 9As shown, the third movable plate 302 is fixed with a blowing member 401, and the sleeve rod 205 is slidably connected with two symmetrically distributed air guide pipes 402, which are connected to the blowing member 401, and the air guide pipe 402 is rotatably connected to the rotating tube 403, which is oriented horizontally, and the axis of the rotating tube 403 is parallel to the axis of the endoscope 207. The direction of the wind blown out by the rotating tube 403 in the horizontal direction is perpendicular to the inner hole of the solid propellant, so that the wind force is more concentrated, and the cleaning ability of the rotating tube 403 on foreign matter on the solid propellant is enhanced. The rotating tube 403 is provided with three blowing holes 406 distributed at equal intervals in the circumferential direction, and the air guide pipe 402 is provided with three ventilation holes distributed at equal intervals in the circumferential direction. The blowing holes 406 are connected to the adjacent ventilation holes, and the rotating tube 4 03 is rotatably connected with a first fixed ring 404, and the first fixed ring 404 is fixed to the lower side of the adjacent first movable rod 209, and the lower side of the fixed plate 210 is fixed with a symmetrically distributed second fixed ring 405, and the second fixed ring 405 is provided with a limiting groove, and the rotating tube 403 is fixed with a spiral protrusion that slides with the limiting groove, and the cross-section of the blowing hole 406 is set in a curved teardrop shape. The endoscope 207 drives the adjacent rotating tube 403 to rotate, and the overlapping area of ​​the blowing hole 406 and the ventilation hole of the air guide pipe 402 becomes larger, thereby increasing the amount of air blown out by the blowing hole 406, so that the blowing hole 406 adjusts its air output according to the inner hole diameter of the solid propellant to avoid excessive wind force damaging the solid propellant or too little wind force resulting in incomplete cleaning of foreign matter.

[0033] When the operator uses the present device to detect and analyze the charge structure integrity of the high-energy solid propellant, the operator turns on the blowing member 401, and the operator drives the rotating disk 103 to rotate by pulling the handle 108. The limiting slide 104 squeezes the three fixing clips 105 to open outward, and the spring between the fixing clip 105 and the connecting frame 102 is compressed. The operator places the solid propellant on the upper side of the support plate 501, and then the operator releases the handle 108. Under the action of the spring force between the fixing clip 105 and the connecting frame 102, the three fixing clips 105 move inward to center and fix the solid propellant.

[0034] In the process of the limiting slide 104 squeezing the three fixing clips 105 to open outward, the fixing clip 105 close to the support frame 201 drives the second movable rod 301 to move outward, the second movable rod 301 drives the third movable plate 302 to move outward, the third movable plate 302 squeezes the inclined rotating plate 306 to drive the movable block 305 to move downward, the spring set on the second limiting rod 304 is compressed, and the movable block 305 squeezes the endoscope 207 through the second electric push rod 208 and the push rod 308, and the lenses of the two symmetrically distributed endoscopes 207 are moved downward. The endoscope 207 extends outward, and drives the first movable rod 209 to move. The first movable rod 209 limits the detection end of the endoscope 207 to prevent it from sagging, resulting in incomplete detection of the inner wall of the solid propellant by the endoscope 207. The distance moved by the rotating plate 306 is proportional to the angle between it and the L-shaped plate 303. The operator controls the telescopic end of the third electric push rod 307 to move up and down, thereby changing the angle between the rotating plate 306 and the L-shaped plate 303, thereby adjusting the length of the endoscope 207 to adapt to the inner diameter size of different solid propellants.

[0035] As the lenses of the two symmetrically distributed endoscopes 207 extend outward, the endoscopes 207 drive the rotating tube 403 to extend outward through the first movable rod 209 and the first fixed ring 404. The rotating tube 403 approaches the inner hole surface of the solid propellant. The blowing member 401 blows air into the rotating tube 403 through the air guide 402. The air blown by the rotating tube 403 cleans the inner hole surface of the solid propellant. As the rotating tube 403 moves, the protrusion of the rotating tube 403 and the first fixed ring 404 are in contact with each other. The limiting grooves of the two fixing rings 405 are limited and matched, so that the rotating tube 403 rotates, and the overlapping area of ​​the blowing hole 406 and the ventilation hole of the air guide tube 402 gradually increases, and the ventilation volume of the blowing hole 406 increases. The larger the diameter of the inner hole of the solid propellant grain, the closer the rotating tube 403 is to the inner wall of the inner hole of the grain, and the greater the ventilation volume of the blowing hole 406, so that the rotating tube 403 can blow away foreign matter attached to the inner hole of the grain, preventing the foreign matter from affecting the operator's assessment of the integrity of the solid propellant charge structure.

[0036] When the endoscope 207 stops moving, the rotating tube 403 stops moving, and the operator turns on the electric roller 107 and the first electric push rod 202. The telescopic end of the first electric push rod 202 drives the third movable plate 302 to move downward through the movable plate 203. The movable plate 203 drives the sleeve rod 205 to move downward through the fixed rod 204. The endoscope 207 and the air guide tube 402 are extended into the inner hole of the six-tooth star-shaped grain of the solid propellant by the drive of the sleeve rod 205. The electric roller 107 drives the solid propellant to rotate, so that the endoscope 207 is aligned with the protrusion of the inner hole of the six-tooth star-shaped grain, and blows The wind blown out from the air hole 406 cleans the foreign matter attached to the inner hole of the solid propellant grain. At the same time, the operator observes and analyzes the cleaned part of the solid propellant through the endoscope 207. When the operator finishes observing the protrusion on one side of the inner hole of the grain, the electric roller 107 drives the solid propellant to rotate 60°, so that the endoscope 207 is aligned with the adjacent protrusion. The operator drives the endoscope 207 and the air guide tube 402 to move upward by controlling the telescopic end of the second electric push rod 208, and the operator observes and analyzes the inner hole of the grain through the endoscope 207.

[0037] Since the inner hole of the solid propellant grain under test is a six-tooth star shape, the endoscope 207 needs to observe the inward concave part of the grain inner hole. Directly using the endoscope 207 to magnify the lens reduces the pixel of the image observed by the operator, affecting the operator's judgment of the grain inner hole structure, resulting in the operator being unable to accurately analyze the structure of the grain inner hole. When the operator needs to observe the concave part of the grain inner hole, the electric roller 107 drives the solid propellant to rotate 30 degrees, so that the endoscope 207 is aligned with the concave part of the grain inner hole, and the second electric push rod 208 is started, and the telescopic end of the second electric push rod 208 is downward. The endoscope 207 is moved and squeezed, and the endoscope 207 projects outward and approaches the depression in the inner hole of the medicine column. In the process of the endoscope 207 projecting outward and approaching the depression in the inner hole of the medicine column, the first fixed ring 404 drives the adjacent tube 403 to project outward, and the rotating tube 403 rotates, so that the ventilation area of ​​the rotating tube 403 gradually increases, and the wind blown out by the rotating tube 403 gradually becomes stronger, so that the rotating tube 403 cleans up foreign matter attached to the depression in the inner hole of the medicine column, preventing foreign matter from interfering with the operator's analysis of the structural integrity of the inner hole of the medicine column, causing the operator to misjudge the structural integrity of the inner hole of the medicine column, resulting in inaccurate test results.

[0038] When the operator has finished observing the inner hole of the solid propellant grain, the operator controls the first electric push rod 202 and the second electric push rod 208 to reset and close the blowing member 401. After the first electric push rod 202 drives the sleeve rod 205 to separate from the inner hole of the solid propellant grain, the operator rotates the rotating disk 103 through the handle 108, and the limiting slide groove 104 squeezes the limiting slider of the fixing clamp 105, so that the three fixing clamps 105 move outward and open. The three fixing clamps 105 release the clamping of the solid propellant, and the operator takes out the solid propellant.

[0039] Example 2

[0040] On the basis of Example 1, Figure 10 and Figure 11 As shown, the support assembly includes four support blocks 502 distributed equidistantly in the circumferential direction, the rotating disk 103 is provided with four limiting holes distributed equidistantly in the circumferential direction, the support blocks 502 distributed equidistantly in the circumferential direction are slidably connected to the adjacent limiting holes, the upper side of the support blocks 502 is fitted with the lower side of the support plate 501, and the four support blocks 502 distributed equidistantly in the circumferential direction are all wrapped with a pull rope, the pull ropes distributed equidistantly in the circumferential direction are fixedly connected to the counterweight block 503, the upper side of the counterweight block 503 is fixedly connected to the support rod 504, and the support rod 504 is fixedly connected to the instant Block 505, the instant block 505 melts rapidly when encountering high temperature. A spring is fixed between the instant block 505 and the support block 502. The burning of the solid propellant causes the instant block 505 to melt rapidly, and the support block 502 no longer supports the support plate 501, thereby stopping the contact between the support plate 501 and the solid propellant, avoiding the interaction force between the solid propellant and the support plate 501 after the solid propellant burns, thereby causing the solid propellant to move upward, causing the solid propellant to break away from the clamping of the three fixing clamps 105, thereby causing danger.

[0041] When the operator observes and analyzes the inner hole of the solid propellant grain, the support block 502 is subjected to the elastic force of the spring between it and the quick-dissolving block 505. At the same time, the support block 502 is also subjected to the pulling force of the counterweight block 503. Unless an accident occurs, the elastic force of the spring between the support block 502 and the quick-dissolving block 505 is sufficient to keep the support block 502 from moving, and the four equally distributed support blocks 502 continue to support the support plate 501.

[0042] When the operator is observing the inner hole of the solid propellant grain, if the operator makes an operational error and causes the solid propellant to burn, the flame ejected by the solid propellant causes the instant block 505 to melt rapidly, the spring fixed to the instant block 505 and the support block 502 loses the support of the instant block 505, the support block 502 loses the elastic force of the spring, the counterweight block 503 pulls the support block 502 out of the limit hole, the support block 502 stops contacting with the support plate 501, the support plate 501 and the support block 502 fall downward, and the support plate 501 stops contacting with the solid propellant, preventing the solid propellant from burning and ejecting flames to generate thrust and move.

[0043] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.
