Description

Technical Field

[0001] This invention relates to the field of hydrogen storage equipment technology, specifically to a testing platform and testing method for solid hydrogen storage materials. Background Technology

[0002] Hydrogen energy is a clean and pollution-free energy source. The use of hydrogen storage alloys for solid-state hydrogen storage and hydrogen supply is a key focus of research in hydrogen storage and release. Hydrogen storage alloys are metallic compounds with strong hydrogen storage capacity. Under certain pressure and temperature conditions, they react with hydrogen to form metal hydrides. When hydrogen is needed, the hydrogen stored in the alloy is released through heating or depressurization, achieving the purpose of hydrogen storage and release. Solid-state hydrogen requires extremely high pressure to form, typically in the range of tens to hundreds of GPa. Therefore, containers for storing solid-state hydrogen need to withstand such high pressure. They are usually made of reinforced materials such as steel, titanium alloys, or carbon fiber, but material testing is also necessary during manufacturing.

[0003] The main testing directions for hydrogen storage tank container materials can be roughly divided into the following two categories: high pressure resistance and low temperature resistance. However, since hydrogen storage materials are mostly in a flat rather than sealed cylindrical shape before they are manufactured, it is impossible to test the pressure resistance of the equipment by injecting high-pressure gas. To address the above issues, the following solutions are proposed. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a testing platform for solid hydrogen storage materials, including a power mechanism, the power mechanism also including an equipment base, an oil storage tank fixedly connected to the top of the equipment base, and an electric telescopic rod fixedly connected to the top of the equipment base;

[0005] The extrusion mechanism includes a fixed square rod fixedly connected to the top of the oil tank, a pressure rod fixedly connected to the top of the oil tank, and a push column slidably connected to the inner wall of the pressure rod.

[0006] The clamping mechanism includes an oil delivery square tube fixedly connected to the outer wall of the pressure rod, the side wall of the oil delivery square tube being fixedly connected to the side wall of the fixed square rod, a pressure box being connected through the side wall of the oil delivery square tube, and a piston square plate being slidably connected to the inner wall of the pressure box.

[0007] Preferably, the power mechanism also includes a pressure pipe that runs through the top of the oil tank. A piston plate is slidably connected to the inner wall of the pressure pipe. A compression frame is fixedly connected to the top of the piston plate. A fixed rod is fixedly connected to the top of the equipment base. A pry bar is rotatably connected to the outer wall of the fixed rod. By utilizing the principle of leverage, when the electric telescopic rod moves, the force generated at the other end will be increased, reducing the resistance encountered by the electric telescopic rod during application.

[0008] Preferably, the power mechanism further includes a sealing plate slidably connected to the inner wall of the oil tank, a return spring fixedly connected to the side wall of the sealing plate, the side wall of the pry bar rotatably connected to the side wall of the extrusion frame, the end of the pry bar away from the extrusion frame rotatably connected to the end of the electric telescopic rod, and an oil outlet is provided on the top of the oil tank.

[0009] Preferably, the power mechanism further includes an oil suction pipe that runs through the bottom of the oil tank, a sliding frame is fixedly connected to the inner wall of the oil suction pipe, a sliding rod is slidably connected to the inner wall of the sliding frame, and a blocking block is fixedly connected to the top of the sliding rod.

[0010] Preferably, the extrusion mechanism further includes a sliding bracket slidably connected to the inner wall of the fixed square rod. An oil storage pipe is fixedly connected to the inner wall of the sliding bracket, and a pressure pipe is slidably connected to the inner wall of the oil storage pipe. A fixed rod is fixedly connected to the outer wall of the pressure pipe. The outer wall of the fixed bracket is fixedly connected to the outer wall of the fixed square rod. A push spring is fixedly connected to the top of the sliding bracket. Taking advantage of the increase in internal liquid during the operation of the pressure rod, the liquid inside the pressure rod enters the pressure chamber through the oil supply square pipe. As the liquid inside the pressure chamber increases, the clamping plate moves downward and forces the clamping plate to press the top of the raw material to be tested. This ensures that the raw material to be tested will not move upward due to excessive bottom pressure during the high-pressure testing process, thus affecting the testing accuracy. Furthermore, as the hydraulic pressure inside the pressure rod increases, the downward pressure of the clamping plate and the upward pushing force of the push column increase simultaneously, enabling the equipment to accommodate materials of various thicknesses and strengthening the clamping force of the equipment around the restricting square plate.

[0011] Preferably, the extrusion mechanism further includes an oil supply pipe connected to the bottom of the fixed square rod. A sliding frame two is fixedly connected to the inner wall of the oil supply pipe, and a sliding rod two is slidably connected inside the sliding frame two. A blocking block two is fixedly connected to the top of the sliding rod two. A pressure tester is fixedly connected to the inner wall of the extrusion frame. Utilizing the characteristic that the liquid inside the sealed space will generate a thrust in all directions after being pressurized, a pressure tester and a test material are installed inside the equipment. When the oil storage pipe is pushed upward by the push column, the space between the oil storage pipe and the pressure pipe decreases, but the internal liquid remains unchanged. At this time, the liquid inside the pressure pipe is squeezed and will generate an expansion force in all directions. This force will be evenly applied to the bottom of the test material and the top of the pressure tester. Through the application of the above components, a gas pressure environment is simulated, avoiding the mutual compression of traditional rigid materials. Under huge extrusion pressure, the outer wall of the hydrogen storage material detection surface will be damaged, and the high-pressure liquid will leak outward through the damaged location, affecting the equipment's detection effect on the material.

[0012] Preferably, the clamping mechanism further includes a clamping plate slidably connected to the inner wall of the pressure chamber, a slide rail fixedly connected to the top of the push column, a push frame slidably connected to the inner wall of the slide rail, a compression ring fixedly connected to the top of the push frame, an expansion air bladder fixedly connected to the inner wall of the pressure pipe, a limiting square plate sleeved on the outer wall of the pressure pipe, and a test material fixedly connected to the top of the limiting square plate. To address the issue that the test materials are mostly flat, an oil storage pipe and a pressure pipe are installed inside the equipment. During actual use, the limiting square plate and the test material are placed on the surface of the pressure pipe, and the power to the electric telescopic rod is turned on. As the electric telescopic rod extends and retracts regularly, it drives the pry bar to rotate. The pry bar controls the piston plate to move up and down through the compression frame. When the piston plate moves up... A low-pressure zone is formed in the lower chamber of the pressure tube. Liquid inside the oil storage tank enters the pressure tube through the suction pipe. When the piston plate descends, the blocking block blocks the suction pipe and forces the liquid inside the pressure tube to enter the pressure rod through the delivery pipe. The liquid inside the pressure rod increases, forcing the push column to move upward. The upward movement of the push column pushes the oil storage tube upward. The top of the pressure tube is hollow, and the liquid inside the pressure tube will directly contact the bottom of the test material. As the upward force of the oil storage tube increases, the liquid inside the pressure tube will be squeezed and generate an expansion force around it. This force will be evenly applied to the bottom of the test material and the top of the pressure tester. Through the application of the above components, the equipment can perform pressure testing on hydrogen storage materials in a flat state.

[0013] A testing platform and testing method for solid hydrogen storage materials, comprising the following steps:

[0014] S1: This invention addresses the problem that most of the test materials are flat. It includes an oil storage pipe and a pressure pipe inside the device. In actual use, the limiting plate and the test material are placed on the surface of the pressure pipe, and the power supply of the electric telescopic rod is turned on.

[0015] S2: As the electric telescopic rod extends and retracts regularly, it drives the pry bar to rotate. The pry bar controls the piston plate to move up and down through the extrusion frame. When the piston plate moves up, high pressure is formed inside the pressure pipe, and the liquid inside the oil tank enters the pressure pipe through the oil suction pipe.

[0016] S3: When the piston plate descends, the block block blocks the oil suction pipe and forces the liquid inside the pressure pipe to enter the pressure rod through the oil delivery pipe. The liquid inside the pressure rod increases and forces the push column to move upward. The upward movement of the push column pushes the oil storage pipe upward. The top of the pressure pipe is hollow, and the liquid inside the pressure pipe will directly contact the bottom of the raw material being tested.

[0017] The present invention has the following beneficial effects:

[0018] (1) This invention addresses the problem that most test materials are flat. It includes an oil storage pipe and a pressure pipe inside the device. In actual use, the limiting plate and the test material are placed on the surface of the pressure pipe, and the power of the electric telescopic rod is turned on. As the electric telescopic rod extends and retracts regularly, it drives the pry bar to rotate. The pry bar controls the piston plate to move up and down through the extrusion frame. When the piston plate moves up, high pressure is formed inside the pressure pipe. The liquid inside the oil storage tank enters the pressure pipe through the oil suction pipe. When the piston plate moves down, the block block blocks the oil suction pipe and forces the liquid inside the pressure pipe to enter the pressure rod through the oil delivery pipe. The liquid inside the pressure rod increases and forces the push column to move upward. The upward movement of the push column pushes the oil storage pipe to move upward. The top of the pressure pipe is hollow, and the liquid inside the pressure pipe will directly contact the bottom of the test material. As the upward movement of the oil storage pipe increases, the liquid inside the pressure pipe will be squeezed and generate an expansion force around it. This force will be evenly applied to the bottom of the test material and the top of the pressure tester. Through the application of the above components, the device can perform pressure testing on hydrogen storage materials in a flat state.

[0019] (2) This invention utilizes the characteristic that the internal liquid of the pressure rod increases during formal operation. The liquid inside the pressure rod enters the pressure box through the oil supply square pipe. As the liquid inside the pressure box increases, the clamping plate moves downward and forces the clamping plate to press the top of the test material. This ensures that the test material will not move upward due to excessive bottom pressure during the high-pressure test, thus affecting the test accuracy. Furthermore, as the hydraulic pressure inside the pressure rod increases, the downward pressure of the clamping plate and the upward pushing force of the pushing column increase simultaneously, enabling the equipment to accommodate test materials of various thicknesses and strengthening the clamping force of the equipment around the restricting square plate.

[0020] (3) This invention utilizes the characteristic of the oil storage pipe moving upward during the detection process. An expansion air bladder is set inside the equipment. When the push column pushes the oil storage pipe upward a certain distance, the top of the oil storage pipe contacts the bottom of the push frame and forces the push frame to move upward. The push frame drives the extrusion ring to squeeze the expansion air bladder, causing the top of the expansion air bladder to expand. The expanded expansion air bladder will fill the gap between the limiting square plate and the pressure pipe, avoiding the high pressure inside the equipment causing the liquid inside the pressure pipe to spray out through the gap, resulting in inaccurate measurement results.

[0021] (4) This invention utilizes the characteristic that when the liquid inside a closed space is pressurized, the entire liquid will generate a thrust in all directions. A pressure tester and a test material are installed inside the equipment. When the oil storage pipe is pushed upward by the push column, the space between the oil storage pipe and the pressure pipe decreases, but the internal liquid remains unchanged. At this time, the liquid inside the pressure pipe is squeezed and will generate an expansion force in all directions. This force will be evenly applied to the bottom of the test material and the top of the pressure tester. Through the application of the above components, the gas pressure environment is simulated, avoiding the mutual squeezing of traditional rigid materials. Under the huge squeezing force, the outer wall of the hydrogen storage material detection surface is damaged, and the high-pressure liquid leaks out through the damaged position, affecting the detection effect of the equipment on the material.

[0037] The clamping mechanism 3 includes an oil delivery square tube 301 fixedly connected to the outer wall of the pressure rod 202. The side wall of the oil delivery square tube 301 is fixedly connected to the side wall of the fixed square rod 201. A pressure box 302 is connected through the side wall of the oil delivery square tube 301. A piston square plate 303 is slidably connected to the inner wall of the pressure box 302.

[0038] The power mechanism 1 also includes a pressure pipe 104 that runs through the top of the oil tank 102. A piston plate 105 is slidably connected to the inner wall of the pressure pipe 104. A compression frame 106 is fixedly connected to the top of the piston plate 105. A fixed rod 107 is fixedly connected to the top of the equipment base 101. A pry bar 108 is rotatably connected to the outer wall of the fixed rod 107. By utilizing the fact that the fixed rod 107 is in a non-central position to the pry bar 108, and by utilizing the lever principle, the force generated at the other end will be increased when the electric telescopic rod 103 moves, thereby reducing the resistance encountered by the electric telescopic rod 103 during application.

[0039] The power mechanism 1 also includes a sealing plate 109 that is slidably connected to the inner wall of the oil storage tank 102. A return spring 110 is fixedly connected to the side wall of the sealing plate 109. The side wall of the pry bar 108 is rotatably connected to the side wall of the extrusion frame 106. The end of the pry bar 108 away from the extrusion frame 106 is rotatably connected to the end of the electric telescopic rod 103. An oil outlet 111 is provided on the top of the oil storage tank 102.

[0040] The power mechanism 1 also includes an oil suction pipe 112 that runs through the bottom of the oil reservoir 102. A sliding frame 113 is fixedly connected to the inner wall of the oil suction pipe 112. A sliding rod 114 is slidably connected to the inner wall of the sliding frame 113. A blocking block 115 is fixedly connected to the top of the sliding rod 114.

[0041] Example 2, please refer to Figure 4 - Figure 8 This invention provides a testing platform for solid hydrogen storage materials. Based on Example 1, the extrusion mechanism 2 further includes a sliding bracket 204 slidably connected to the inner wall of the fixed square rod 201. An oil storage pipe 205 is fixedly connected to the inner wall of the sliding bracket 204, and a pressure pipe 206 is slidably connected to the inner wall of the oil storage pipe 205. A fixed rod 107 is fixedly connected to the outer wall of the pressure pipe 206. The outer wall of the fixed bracket 207 is fixedly connected to the outer wall of the fixed square rod 201. A push spring 208 is fixedly connected to the top of the sliding bracket 204. During operation, the pressure rod 202 increases the internal liquid level... Features: The liquid inside the pressure rod 202 enters the pressure box 302 through the oil supply square pipe 301. As the liquid inside the pressure box 302 increases, the clamping plate 304 moves downward and forces the clamping plate 304 to press the top of the raw material to be tested. This ensures that the raw material to be tested will not move upward due to excessive bottom pressure during the high-pressure testing process, thus affecting the testing accuracy. Furthermore, as the hydraulic pressure inside the pressure rod 202 increases, the downward pressure of the clamping plate 304 and the upward pushing force of the pushing column 203 increase simultaneously, enabling the equipment to accommodate testing materials of various thicknesses and strengthening the clamping force of the equipment on the surrounding area of ​​the restricting square plate 309.

[0042] The extrusion mechanism 2 also includes an oil supply pipe 209 that runs through the bottom of the fixed square rod 201. A sliding frame 210 is fixedly connected to the inner wall of the oil supply pipe 209. A sliding rod 211 is slidably connected inside the sliding frame 210. A blocking block 212 is fixedly connected to the top of the sliding rod 211. A pressure tester 213 is fixedly connected to the inner wall of the extrusion frame 106. Utilizing the characteristic that the liquid inside the sealed space will generate a thrust in all directions after being pressurized, a pressure tester 213 and a raw material testing device 310 are installed inside the equipment. When the push column 203 pushes the oil storage pipe 205 upward, the space between the oil storage pipe 205 and the pressure pipe 206 decreases, but the internal liquid remains unchanged. At this time, the liquid inside the pressure pipe 206 is squeezed and will generate an expansion force around it. This force will be evenly applied to the bottom of the detection material 310 and the top of the pressure tester 213. Through the application of the above components, the gas pressure environment is simulated to avoid the mutual compression of traditional rigid materials. Under the huge extrusion force, the outer wall of the hydrogen storage material detection surface is damaged, and the high-pressure liquid leaks outward through the damaged position, affecting the detection effect of the equipment on the material.

[0043] The clamping mechanism 3 also includes a clamping plate 304 slidably connected to the inner wall of the pressure chamber 302. A slide rail 305 is fixedly connected to the top of the push column 203. A push frame 306 is slidably connected to the inner wall of the slide rail 305. A compression ring 307 is fixedly connected to the top of the push frame 306. An expansion air bladder 308 is fixedly connected to the inner wall of the pressure pipe 206. A limiting square plate 309 is sleeved on the outer wall of the pressure pipe 206. A test material 310 is fixedly connected to the top of the limiting square plate 309. To address the issue that the test materials are mostly flat, an oil storage pipe 205 and a pressure pipe 206 are installed inside the equipment. In actual use, the limiting square plate 309 and the test material 310 are placed on the surface of the pressure pipe 206, and the power supply of the electric telescopic rod 103 is turned on. As the electric telescopic rod 103 extends and retracts regularly, it drives the pry bar 108 to rotate. The pry bar 108 controls the piston plate 105 to move up and down through the compression frame 106. When the piston plate When the piston plate 105 moves upward, a low-pressure zone is formed in the lower chamber of the pressure tube 104. The liquid inside the oil storage tank 102 enters the pressure tube 104 through the oil suction pipe 112. When the piston plate 105 descends, the blocking block 115 blocks the oil suction pipe 112 and forces the liquid inside the pressure tube 104 to enter the pressure rod 202 through the oil delivery pipe 209. The liquid inside the pressure rod 202 increases and forces the push column 203 to move upward. The upward movement of the push column 203 pushes the oil storage tube 205 upward. The top of the pressure tube 206 is hollow, and the liquid inside the pressure tube 206 will directly contact the bottom of the test material 310. As the upward force of the oil storage tube 205 increases, the liquid inside the pressure tube 206 will be squeezed and generate an expansion force around it. This force will be evenly applied to the bottom of the test material 310 and the top of the pressure tester 213. Through the application of the above components, the equipment can perform pressure testing on hydrogen storage materials in a flat state.

[0044] The manufacturing method of this manufacturing apparatus includes the following steps:

[0045] S1: In view of the problem that most of the test materials are flat, the present invention has an oil storage pipe 205 and a pressure pipe 206 inside the equipment. When in use, the limiting plate 309 and the test material 310 are placed on the surface of the pressure pipe 206 and the power supply of the electric telescopic rod 103 is turned on.

[0046] S2: As the electric telescopic rod 103 extends and retracts regularly, it drives the pry bar 108 to rotate. The pry bar 108 controls the piston plate 105 to move up and down through the extrusion frame 106. When the piston plate 105 moves up, a low-pressure area will be formed in the lower chamber of the pressure pipe 104. The liquid inside the oil tank 102 enters the pressure pipe 104 through the oil suction pipe 112.

[0047] S3: When the piston plate 105 descends, the block block 115 blocks the oil suction pipe 112 and forces the liquid inside the pressure pipe 104 to enter the pressure rod 202 through the oil delivery pipe 209. The liquid inside the pressure rod 202 increases and forces the push column 203 to move upward. The upward movement of the push column 203 pushes the oil storage pipe 205 upward. The top of the pressure pipe 206 is hollow, and the liquid inside the pressure pipe 206 will directly contact the bottom of the detection material 310.

[0048] A specific application of this embodiment is as follows: In formal use, the limiting plate 309 and the detection material 310 are placed on the surface of the pressure tube 206, and the power supply of the electric telescopic rod 103 is turned on. As the electric telescopic rod 103 extends and retracts regularly, it drives the pry bar 108 to rotate. The pry bar 108 controls the piston plate 105 to move up and down through the extrusion frame 106. When the piston plate 105 moves upward, a low-pressure area is formed in the lower chamber of the pressure tube 104. The liquid inside the oil tank 102 enters the pressure tube 104 through the oil suction pipe 112. When the piston plate 105 descends, the blocking block 115 blocks the oil suction pipe 112 and forces the liquid inside the pressure tube 104 to enter the pressure rod 202 through the oil delivery pipe 209. The increased liquid inside the pressure rod 202 forces the pusher column 203 to move upwards. This upward movement of the pusher column 203 pushes the oil storage pipe 205 upwards. The pressure pipe 206 has a hollow top, allowing the liquid inside to directly contact the bottom of the test material 310. Utilizing the characteristic that the liquid inside a confined space, after being pressurized, will generate a thrust in all directions, the device contains a pressure tester 213 and the test material 310. When the oil storage pipe 205 is pushed upwards by the pusher column 203, the space between the oil storage pipe 205 and the pressure pipe 206 decreases, but the internal liquid level remains unchanged. At this time, the liquid inside the pressure pipe 206 is compressed, generating an expansion force in all directions. This force will act evenly on the bottom of the test material 310 and the pressure pipe 206. At the top of the force tester 213, the aforementioned components simulate a gas pressure environment, enabling the device to perform pressure tests on hydrogen storage materials in a flat state. Utilizing the characteristic of increased internal liquid in the pressure rod 202 during operation, the liquid enters the pressure chamber 302 through the oil supply square pipe 301. As the liquid level in the pressure chamber 302 increases, the clamping plate 304 moves downwards, forcing it to press against the top of the test material. This ensures that during high-pressure testing, the test material will not rise due to excessive bottom pressure, affecting testing accuracy. Furthermore, as the hydraulic pressure inside the pressure rod 202 increases, the downward pressure of the clamping plate 304 and the upward pushing force of the pushing column 203 increase simultaneously. This design enables the equipment to accommodate materials of various thicknesses and strengthens the clamping force around the limiting plate 309. Utilizing the upward movement of the oil storage pipe 205 during testing, an expansion air bladder 308 is installed inside the equipment. When the pushing column 203 pushes the oil storage pipe 205 upward a certain distance, the top of the oil storage pipe 205 contacts the bottom of the pushing frame 306, forcing the pushing frame 306 to move upward. The pushing frame 306 then drives the compression ring 307 to compress the expansion air bladder 308, causing the top of the expansion air bladder 308 to expand. The expanded expansion air bladder 308 fills the gap between the limiting plate 309 and the pressure pipe 206, preventing the high pressure inside the equipment from causing the liquid inside the pressure pipe 206 to spray out through the gap, thus avoiding inaccurate measurement results.

During actual use, the limiting plate and the test material are placed on the surface of the pressure pipe, and the power supply of the electric telescopic rod is turned on. S2: As the electric telescopic rod extends and retracts regularly, it drives the pry bar to rotate. The pry bar controls the piston plate to move up and down through the extrusion frame. When the piston plate moves up, a low-pressure area is formed in the lower chamber of the pressure pipe. The liquid inside the oil tank enters the pressure pipe through the oil suction pipe. S3: When the piston plate descends, the block block blocks the oil suction pipe and forces the liquid inside the pressure pipe to enter the pressure rod through the oil delivery pipe. The liquid inside the pressure rod increases and forces the push column to move upward. The upward movement of the push column pushes the oil storage pipe upward. The top of the pressure pipe is hollow, and the liquid inside the pressure pipe will directly contact the bottom of the raw material being tested.
