Description

Technical Field

[0001] The invention relates to the technical field of steel cylinder water pressure testing, in particular to a steel cylinder water pressure testing device based on the production of liquefied petroleum gas steel cylinders. Background Art

[0002] The liquefied petroleum gas cylinder water pressure test device is an important equipment used to test the pressure bearing capacity and sealing performance of the cylinder. It is widely used in the production and inspection of liquefied petroleum gas cylinders.

[0003] Existing hydraulic testing equipment for liquefied petroleum gas cylinders may cause leakage during hydraulic testing of cylinders without rapid pressure relief, which may lead to the following disadvantages and potential risks:

[0004] ①During the hydraulic test of a cylinder, the pressure inside the cylinder is usually high. If the leakage is not relieved quickly, the pressure will continue to act on the cylinder, which may easily cause the cylinder to rupture or even explode due to overpressure, endangering personnel safety;

[0005] ② Leaked water or gas may cause corrosion to the inside or outside of the cylinder, which may easily cause fire or chemical explosion. At the same time, slow leakage may easily lead to local stress concentration in the cylinder, increase the risk of fatigue cracks, and shorten the service life of the cylinder;

[0006] ③ If the cylinder leaks but the pressure is not released quickly, it is easy to cause inaccurate pressure gauge readings, which cannot truly reflect the pressure resistance performance of the cylinder, thereby affecting the reliability of the test results. In addition, the failure to release the pressure quickly will increase the test time and reduce the detection efficiency, especially in batch testing, which may significantly affect production efficiency.

[0007] In addition, leaked water requires additional cleaning work, increasing the test cost, and the test water cannot be quickly recycled or discharged, which will lead to a waste of water resources. At the same time, the leaked test water will pollute the environment, especially if it is not properly handled. Therefore, during the cylinder water pressure test, if the leakage is not quickly relieved, it will bring serious safety hazards, equipment damage risks, distorted test results, and reduced operating efficiency. Therefore, during the test, it is necessary to ensure that the leakage can be relieved quickly;

[0008] At the same time, when the cylinder is subjected to a water pressure test, the cylinder itself will generate heat. The heat is mainly generated by the friction and resistance between molecules when the water inside the cylinder is pressurized. Although this heat is usually not large, it may be necessary to control or absorb this heat in some cases to maintain the stability of the test environment or prevent overheating from affecting the cylinder material. Therefore, it needs to be improved. Summary of the Invention

[0045] By utilizing the above structure, through the setting of the water receiving bucket 28 and the shape characteristics of the water receiving bucket 28, it can be seen that the water receiving bucket 28 can receive and recycle the water on the inner wall of the cylinder body 8, which can effectively avoid the waste of water resources. At the same time, when the water suction pump 32 is started, the water source on the inner wall of the water receiving bucket 28 can be adsorbed to the inner wall of the water outlet pipe 33 through the water inlet pipe 31, and transported to the inner wall of the main water tank 25, which solves the problem that the test water cannot be recycled in the existing device, resulting in waste of water resources, and the leaked test water will cause pollution to the environment.

[0046] In a preferred embodiment, the inner wall of the water outlet 30 is clamped with a water inlet pipe 31, the bottom of the base 2 is installed with a water suction pump 32, the outer wall of the water suction pump 32 is provided with a water outlet pipe 33, the inner cavity of the square groove 3 is provided with a micro motor 34, and the power output shaft of the micro motor 34 is fixedly equipped with a threaded rod 35;

[0047] In a preferred embodiment, the water suction pump 32 and the micro motor 34 are both electrically connected to the remote control terminal. The threaded rod 35 is located on the inner wall of the chute 4 and is threadedly connected to the inner wall of the block 5. There are five chute slots 4, and the five chute slots 4 are evenly distributed in the inner cavity of the base 2.

[0048] By utilizing the above structure, the micro motor 34 can be started by transmitting a signal through the remote control terminal, so that the threaded rod 35 can rotate, so that it can drive the block 5 to move on the inner wall of the slide 4, and the block 5 can drive the centrifugal motor 6 to move synchronously, so that the top of the disc 7 can be separated from the bottom of the cylinder body 8 and move toward the main water tank 25, so that the square groove 3 can be completely exposed, so that the cylinder body 8 can quickly discharge the test water inside it.

[0049] In a preferred embodiment, the output end of the water suction pump 32 is connected to the water outlet pipe 33, and the input end of the water suction pump 32 is connected to the water inlet pipe 31. One end of the water outlet pipe 33 is connected to the outer wall of the water suction pump 32, and the other end of the water outlet pipe 33 is located on the inner wall of the main water tank 25. The electric telescopic cylinder 17, the water injection pump 19 and the air pump 24 are all electrically connected to the remote control terminal. The inner walls of the water supply pipe 20 and the air supply pipe 23 are both connected to the inner wall of the injection pipe 21.

[0050] Utilizing the above structure, through the characteristic that the inner walls of the water pipe 20 and the air pipe 23 are both connected to the inner wall of the injection pipe 21, it can be seen that after the water injection pump 19 is started to transport water to the inner wall of the injection pipe 21, the air pump 24 can be started to transport hot air to the inner wall of the injection pipe 21 through the air pipe 23, so that hot air can be blown to the inner wall of the cylinder body 8, and the inner wall of the cylinder body 8 can be dried.

[0051] In a preferred embodiment, the drainage assembly 9 includes a drive motor 91, a power output shaft of the drive motor 91 is fixedly equipped with a driving gear 92, an outer wall of the driving gear 92 is meshed with one end of a rack 93, and the inner wall of the other end of the rack 93 is meshed with a driven gear 94, an outer wall of the driven gear 94 is fixedly mounted with one end of a connecting disk 95, an outer wall of the other end of the connecting disk 95 is fixedly mounted with a pneumatic cylinder 96, the telescopic end of the pneumatic cylinder 96 is fixedly mounted with an arc-shaped clamping plate 97, the outer wall of the arc-shaped clamping plate 97 is provided with a phase change plate 98, and the outer wall of the phase change plate 98 is fixedly mounted with a permanent magnet 99;

[0052] There are two permanent magnets 99, and the two permanent magnets 99 are symmetrically distributed at both ends of the cylinder body 8. A telescopic tube 910 is fixedly installed on the outer wall of the permanent magnet 99 on the side away from the drive motor 91. The top of the telescopic tube 910 is connected to the receiving end of the air pump 24.

[0053] By utilizing the above structure, the drive motor 91 and the pneumatic cylinder 96 can be started by transmitting a signal through the remote control terminal, so that the pneumatic cylinder 96 can drive the arc-shaped clamping plate 97 to extend and retract toward the cylinder body 8, and the two phase change plates 98 can clamp and fix the cylinder body 8. At this time, the driving gear 92 rotates, and the driven gear 94 is driven to rotate synchronously through the rack 93, so that the pneumatic cylinder 96 can drive the cylinder body 8 to automatically flip through the arc-shaped clamping plate 97, so that the cylinder body 8 can quickly drain water. In this process, the phase change plate 98 can absorb the heat generated by the cylinder body 8, and because the permanent magnet 99 can be magnetized under the control of the power supply and the remote control terminal, the phase change plate 98 can absorb heat during magnetization and store its heat. During demagnetization, the released heat will be transported to the inner wall of the air pump 24 through the telescopic tube 910. The heat release process can be flexibly designed according to actual needs to improve the efficiency of heat energy utilization.

[0054] In a preferred embodiment, the number of the pneumatic cylinder 96, the arc-shaped clamping plate 97, and the phase change plate 98 is two, and the two pneumatic cylinders 96, the arc-shaped clamping plate 97, and the phase change plate 98 are symmetrically distributed at both ends of the cylinder body 8. The permanent magnet 99 is electrically connected to the remote control terminal via a power supply, the drive motor 91 and the pneumatic cylinder 96 are both electrically connected to the remote control terminal, and the phase change plate 98 is made of a magnetic alloy.

[0055] By utilizing the above structure and the characteristic that the phase change plate 98 is made of a magnetic alloy, it can be seen that the phase change plate 98 can achieve the effects of efficient storage, conversion and utilization of thermal energy, and can effectively avoid the need to control or absorb such heat in certain circumstances to maintain the stability of the test environment or prevent overheating from affecting the cylinder material.

[0056] In a preferred embodiment, the pressure relief assembly 12 includes a connecting pipe 121, the outer wall of the connecting pipe 121 is provided with a sealing detection assembly 122, a one-way valve 123 is installed on the top of the connecting pipe 121, and a fixing plate 124 is fixedly installed on the outer walls of both sides of the one-way valve 123. A motor 125 is fixedly installed on the bottom of the fixing plate 124. The power output shaft of the motor 125 is fixedly assembled with a screw rod 126. The outer wall of the screw rod 126 is respectively threadedly connected to a rotating handle 127 and a rotating handle 2 128. The outer wall of the rotating handle 127 is rotatably connected to an abutment block 129, and the outer wall of the rotating handle 2 128 is rotatably connected to a connecting block 1210.

[0057] The sealing detection assembly 122 includes a branch pipe 1221. The inner wall of the branch pipe 1221 is provided with an arc film 1 1222 and an arc film 2 1223. The inner walls of the arc film 1 1222 and the arc film 2 1223 are both fixedly embedded with an electrode chip 1224.

[0058] Utilizing the above structure, when leakage occurs through the inner wall of the steel cylinder body 8, the pressure on the inner wall of the branch pipe 1221 will change, thereby causing the two electrode chips 1224 embedded in the inner walls of the arc-shaped film 1 1222 and the arc-shaped film 2 1223 to contact each other. At this time, current will pass through, and a signal will be emitted to enable the alarm light 15 to sound an alarm and flash alternately, so that the staff can know in time which steel cylinder body 8 is leaking, without the need for manual intervention and marking, so the labor intensity is low. At the same time, the motor 125 can be started to rotate the screw rod 126, which can drive the angle between the rotating handle 1 127 and the rotating handle 2 128 to change, so that the outer wall of the abutment block 129 can be separated from the inner wall of the steel cylinder body 8, thereby achieving the purpose of rapid pressure relief.

[0059] In a preferred embodiment, the electrode chip 1224 is electrically connected to the motor 125 and the alarm light 15. The outer wall of the abutment block 129 abuts the inner wall of the cylinder body 8. The outer wall of the connection block 1210 is fixedly mounted on the outer wall of the connecting pipe 121. The one-way valve 123 is electrically connected to the remote control terminal. The connecting pipe 121 is plugged into the top inner wall of the cylinder body 8. Both ends of the arc film 1 1222 and the arc film 2 1223 are fixedly mounted on the inner wall of the branch pipe 1221. The cross-sections of the arc film 1 1222 and the arc film 2 1223 are both arc-shaped. The inner wall of the branch pipe 1221 is connected to the inner wall of the connecting pipe 121.

[0060] By utilizing the above structure, by inserting the connecting tube 121 into the bottle mouth of the cylinder body 8, and making the remote control terminal transmit a signal to start the motor 125, and rotating the screw rod 126, the angle between the rotating handle 127 and the rotating handle 2 128 can be changed, so that the outer wall of the abutment block 129 can abut against the top inner wall of the cylinder body 8, the connecting tube 121 can be stably placed at the bottle mouth of the cylinder body 8, and the injection pipe 21 can be used to inject water and inflate the inner wall of the cylinder body 8 through the one-way valve 123.

[0061] Working principle: when the device performs a water pressure test on the cylinder body 8, the water receiving bucket 28 is pulled open, and the cylinder body 8 is placed on the top of the disc 7, and the water receiving bucket 28 is pushed back. At this time, the remote control terminal can transmit a signal to start the drive motor 91 and the pneumatic cylinder 96, so that the pneumatic cylinder 96 can drive the arc clamping plate 97 to extend and retract in the direction of the cylinder body 8, and the two phase change plates 98 clamp and fix the cylinder body 8. In this process, the remote control terminal transmits a signal to start the drive motor 91 and the pneumatic cylinder 96, so that the pneumatic cylinder 96 can drive the arc clamping plate 97 to extend and retract in the direction of the cylinder body 8. 8 is extended and retracted, and the two phase change plates 98 clamp and fix the cylinder body 8. At this time, the driving gear 92 is rotated, and the driven gear 94 is driven to rotate synchronously through the rack 93, so that the pneumatic cylinder 96 can drive the cylinder body 8 to automatically flip through the arc-shaped clamping plate 97, so that the cylinder body 8 can quickly drain water. In this process, the phase change plate 98 can absorb the heat generated by the cylinder body 8. Since the permanent magnet 99 can be magnetized under the control of the power supply and the remote control terminal, the phase change plate 98 can absorb heat during magnetization and store the heat.

[0062] The connecting tube 121 is inserted into the mouth of the cylinder body 8. At this time, the remote control terminal transmits a signal to start the motor 125, and after the screw rod 126 is rotated, the angle between the rotating handle 127 and the rotating handle 2 128 can be changed, so that the outer wall of the abutting block 129 can abut against the top inner wall of the cylinder body 8. The connecting tube 121 can be stably placed at the mouth of the cylinder body 8, and the injection pipe 21 can be used to inject water and gas into the inner wall of the cylinder body 8 through the one-way valve 123.

[0063] When the inner wall of the cylinder body 8 leaks, the pressure on the inner wall of the branch pipe 1221 will change, so that the two electrode chips 1224 embedded in the inner walls of the arc film 1 1222 and the arc film 2 1223 will come into contact. At this time, current will pass through, and a signal will be emitted to enable the alarm light 15 to sound an alarm and flash alternately, so that the staff can know in time which cylinder body 8 is leaking, without the need for manual intervention and marking, so the labor intensity is low. At the same time, the motor 125 can be started to rotate the screw rod 126, which can drive the angle between the rotating handle 1 127 and the rotating handle 2 128. When the cylinder body 8 is in the air, the outer wall of the abutment block 129 can be separated from the inner wall of the cylinder body 8, thereby achieving the purpose of rapid pressure relief. After the pressure relief is completed, when the remote control terminal transmits a signal, the centrifugal motor 6 can be started, and the cylinder body 8 can be driven by the disc 7 to shake on the inner wall of the drainage assembly 9, so that the cylinder body 8 can rotate at high speed around the central axis of the disc 7, and the centrifugal force is used to throw the water in the cylinder body 8 to the bottle wall, and the driven gear 94 is driven by the rack 93 to rotate synchronously, so that the pneumatic cylinder 96 can drive the cylinder body 8 to automatically flip over through the arc-shaped clamping plate 97;

[0064] At this time, the micro motor 34 can be started, so that the threaded rod 35 can rotate, so that it can drive the block 5 to move on the inner wall of the slide 4, and the block 5 can drive the centrifugal motor 6 to move synchronously, so that the top of the disc 7 can be separated from the bottom of the cylinder body 8 and move toward the main water tank 25, so that the square groove 3 can be completely exposed, so that the cylinder body 8 can quickly discharge the test water inside the cylinder body 8 from the bottle mouth after tilting, and transmit gas to the inner wall of the injection pipe 21 through the gas pipe 23. During demagnetization, the released heat will be transmitted to the inner wall of the air pump 24 through the telescopic tube 910, so that it can heat the gas. When the air pump 24 is started, it can transmit hot gas to the inner wall of the gas pipe 23, and the inner wall of the cylinder body 8 can be dried.

[0065] The test water can be collected on the inner wall of the water receiving bucket 28, which can effectively avoid the waste of water. At the same time, when the water suction pump 32 is started, the water on the inner wall of the water receiving bucket 28 can be adsorbed to the inner wall of the water outlet pipe 33 through the water inlet pipe 31 and transported to the inner wall of the main water tank 25, so that the test water can be recycled, so that the device can recycle the test water while performing a water pressure test on the cylinder body 8.
