A withstand voltage testing device for a self-powered temperature acquisition system

Abstract

This invention discloses a withstand voltage testing device for a self-powered temperature acquisition system, belonging to the technical field of testing devices. It includes a support block with a controller mounted on its outer surface and a testing component for detecting the withstand voltage strength of the self-powered temperature acquisition system located near the center of the top of the support block. When performing withstand voltage testing on a self-powered temperature acquisition system used for connectors, if the gas sensor detects excessively high levels of [unspecified substance] in the test chamber, the arc-shaped protective chamber moves downwards, causing the sealing ring to move downwards into the slot. The gas generated by the explosion first enters the cavity to filter out dust, then cools down through a threaded tube before flowing back into the arc-shaped protective chamber. This process is repeated until the temperature in the flow tube reaches the required value.

Description

Technical Field

[0001] This invention relates to the field of testing device technology, specifically to a pressure testing device for a self-powered temperature acquisition system. Background Technology

[0002] A self-powered temperature acquisition system for connectors is a miniature device integrated inside the connector. It can autonomously acquire energy and monitor the connector's operating temperature in real time. Ultimately, it transmits temperature data wirelessly or via wired means to provide early warning and status monitoring of connector overheating risks. Its core features are self-powered operation and targeted temperature acquisition, specifically adapted to the confined space, dynamic working environment, and safety requirements of connectors. The self-powered temperature acquisition system withstand pressure test device is a device specifically used to test whether the self-powered temperature acquisition system can work normally and maintain structural integrity and data reliability under specific pressure environments. It mainly simulates the high-pressure conditions that the system may face in actual applications to verify its pressure resistance, sealing performance, and the stability of its temperature acquisition function.

[0003] Existing self-powered temperature acquisition systems for connectors often use lithium batteries as their energy source. During withstand voltage testing, the batteries are subjected to pressure, which can easily lead to internal short circuits and thermal runaway. If the battery's internal separator is punctured, the positive and negative electrodes come into direct contact, generating a large amount of heat instantly and causing the battery temperature to rise sharply, releasing flammable gases. When these gases accumulate to a certain concentration in the test chamber, they can explode upon contact with an ignition source. Most existing withstand voltage testing equipment only provides physical protection on the outside of the testing device. However, the destructive effect of an explosion is not a single impact but rather the simultaneous release of energy through shock waves, flying debris, high-temperature flames, and toxic gases. Physical protection is insufficient to completely block these effects, thus posing a threat to the personal safety of the personnel conducting the tests.

[0004] Therefore, we propose a self-powered temperature acquisition system withstand voltage testing device to solve the problems mentioned above. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. During the withstand voltage test of a self-powered temperature acquisition system used for connectors, when the gas sensor detects gas inside the test chamber... and When the content is too high, the arc-shaped protective chamber is moved downward, causing the sealing ring to move downward into the inside of the slot. The gas generated by the explosion first enters the cavity to filter the dust, and then flows back to the arc-shaped protective chamber after being cooled through the threaded pipe.

[0018] 2. After the self-powered temperature acquisition system is placed in the test chamber, a pressure test can be performed on the system. During the pressure test, if the lithium battery inside the acquisition system is damaged, it will release... and At that time, if and The content of In between, the control valve is opened to release a portion of the combustible gas inside the test chamber. Simultaneously, argon gas is introduced into the test chamber to replace the gas inside, until the gas sensor detects that the content of combustible and oxidizing gases in the test chamber reaches the standard value. Through the action of the test components, the acquisition system in the self-powered temperature acquisition system withstand pressure test device is effectively prevented from releasing gas under high pressure. and And it can lead to an explosion at high temperatures.

[0035] Please see Figures 1-6As shown, the present invention provides a technical solution: a pressure resistance testing device for a self-powered temperature acquisition system. The testing component 3 includes a pressure-resistant plate 301, the bottom of which is fixedly connected to the top of a support block 1. A slot 302 is provided near the center of the top of the pressure-resistant plate 301. A test chamber 303 is fixedly installed on the top of the pressure-resistant plate 301. A gas sensor 304 is installed on the top surface inside the test chamber 303, and a pressure sensor 305 is installed on the inner wall of the test chamber 303. A pressure-resistant frame 306 is fixed to the outer surface of the pressure-resistant plate 301, and a drive motor 307 is fixedly installed on the outer surface of the pressure-resistant frame 306 by screws. A drive shaft 308 is fixedly connected to the output end of the machine 307. A drive gear 309 is fixedly sleeved on the outer surface of the drive shaft 308. One end of the drive shaft 308 moves sequentially through the outside of the pressure-resistant frame 306 to the inner wall of the pressure-resistant plate 301. A driven gear 310 is meshed with the outer surface of the drive gear 309. An electric push rod 311 is set on the outer surface of the driven gear 310 through an I-shaped auxiliary block. A connecting block 312 is fixedly installed on one end of the electric push rod 311. An operating table 314 is slidably connected to the inner wall of the test chamber 303. A positioning buckle 313 is fixedly installed on the outer surface of the operating table 314. The outer surface of the test chamber 303... A connecting pipe 315 is fixedly connected, and a control valve 316 is installed on the outer surface of the connecting pipe 315. One end of the connecting pipe 315 is fixedly connected to an output pipe 317. A recycling tank 318 is fixedly installed on the top of the support block 1 by screws. The bottom end of the output pipe 317 is fixedly inserted into the interior of the recycling tank 318. An exhaust pump 319 is installed on the top of the test chamber 303 near one edge. The input end of the exhaust pump 319 is fixedly connected to a connecting pipe 320. The bottom end of the connecting pipe 320 is fixedly inserted into the interior of the test chamber 303. A second delivery pump 321 is installed on the top of the pressure plate 301 through an auxiliary frame. The second delivery pump 321... The output end is fixedly connected to a drain pipe 322, the bottom end of which is fixedly inserted into the interior of the test chamber 303. The top of the pressure plate 301 is fixedly mounted with a gas tank 323 via an auxiliary frame. The input end of the second delivery pump 321 is fixedly connected to a delivery pipe 324, one end of which is fixedly inserted into the interior of the gas tank 323. Rotary bolts 325 are movably embedded in the inner wall of the operating table 314 near the four corners. Fixed threaded holes 326 are fixed in the inner wall of the test chamber 303 near the four corners. The outer surfaces of the four rotating bolts 325 are threadedly connected to the inner walls of the four fixed threaded holes 326 respectively.

[0036] In this embodiment, when a withstand voltage test is required on a self-powered temperature acquisition system used for a connector, and the battery in the acquisition system is a lithium battery, the acquisition system to be measured is first placed on top of the operating table 314 and fixed using an external positioning device. Then, the electric push rod 311 can be activated by the controller 2 to extend it, causing the connecting block 312 to move forward until the connecting block 312 is inserted into the positioning buckle 313. For example... Figure 4 As shown, the cross-section of the connecting block 312 is the same as that of the center hole of the positioning buckle 313. This is to facilitate the insertion of the connecting block 312 into the positioning buckle 313. Once the connecting block 312 is inserted into the positioning buckle 313, the drive motor 307 can be started, driving the drive shaft 308 to rotate, which in turn drives the drive gear 309 to rotate, thereby causing the driven gear 310 to rotate, which in turn drives the electric push rod 311 to rotate. This achieves the connection between the connecting block 312 and the positioning buckle 313, allowing the electric push rod 311 to push the operating table 314 into the test chamber 303 until the outer surface of the operating table 314 is in complete contact with the inner wall of the test chamber 303. For example... Figure 4 As shown, a high-temperature resistant sealing strip is provided on the outer surface of the operating platform 314 to ensure the airtightness between the operating platform 314 and the test chamber 303. Additionally, as the operating platform 314 moves forward, it drives the four rotating bolts 325 forward until they are inserted into their corresponding threaded holes 326. The operator can then manually rotate the four rotating bolts 325 with a screwdriver until they are fully inserted into the deepest part of their respective threaded holes 326, thus securing the operating platform 314 and placing the self-powered temperature acquisition system. The drive motor 307 can then be restarted to rotate the electric actuator 311 in the opposite direction. Then the electric actuator 311 can be activated again to move the connecting block 312 out of the positioning buckle 313.

[0037] like Figures 1-6 As shown, a control valve 316 is provided on the outer surface of the connecting pipe 315, and an output pipe 317 is fixedly connected to one end of the connecting pipe 315. A recycling tank 318 is fixedly installed on the top of the support block 1 by screws. The bottom end of the output pipe 317 is fixedly inserted into the interior of the recycling tank 318. An exhaust pump 319 is provided on the top of the test chamber 303 near one side edge. The input end of the exhaust pump 319 is fixedly connected to a connecting pipe 320. The bottom end of the connecting pipe 320 is fixedly inserted into the interior of the test chamber 303. A second delivery pump 321 is provided on the top of the pressure plate 301 through an auxiliary frame. The output end of the second delivery pump 321 is fixedly connected to a drain pipe 322.

[0038] In this embodiment, after the self-powered temperature acquisition system is placed inside the test chamber 303, the exhaust pump 319 is first started, driving the connecting pipe 320 to draw gas into the test chamber 303, and the result is displayed by the pressure sensor 305. The core function of the pressure sensor 305 is to convert the pressure signal inside the test chamber 303 into a measurable electrical signal. Through analysis and processing of the electrical signal, the pressure value is finally obtained. When the pressure sensor 305 detects a certain pressure value inside the test chamber 303, it indicates that the air inside the test chamber 303 has been emptied, and then the controller can... 2. Turn off the exhaust pump 319 and simultaneously start the second delivery pump 321, which drives the delivery pipe 324 to draw inert argon gas into the gas tank 323. The argon gas enters the test chamber 303 through the guide pipe 322, creating high pressure inside the test chamber 303, which is displayed by the pressure sensor 305. When the pressure sensor 305 detects that the pressure inside the test chamber 303 reaches a certain value, the second delivery pump 321 is turned off, maintaining that pressure value inside the test chamber 303 for a certain period of time. At the same time, the gas sensor 304 is activated to detect whether there is any gas inside the test chamber 303. and To prevent explosions, the gas sensor 304 detects the type and concentration of gas inside the test chamber 303. The core principle is to utilize the chemical reaction between the sensor and the target gas to convert the gas's chemical information into a measurable electrical signal. Signal processing and analysis then determine the gas type and concentration. Different types of sensors have significantly different principles. Gas inside the test chamber 303 is pumped into the sensor's detection area. The sensor converts the gas's chemical properties into an electrical signal. The circuit amplifies, filters, and performs AD conversion on the original electrical signal. The microcontroller compares the processed signal with a calibration curve to calculate the gas type and concentration. When the gas sensor 304 detects gas inside the test chamber 303... and The content of During this process, to prevent an explosion inside the test chamber 303, the controller 2 opens the control valve 316 to release some of the combustible gas inside the test chamber 303. Simultaneously, the second delivery pump 321 is restarted to continue supplying argon gas into the test chamber 303, thus replacing the gas inside. This continues until the gas sensor 304 detects that the content of combustible and oxidizing gases inside the test chamber 303 reaches the standard value. Through the function of the test component 3, the pressure testing device of the self-powered temperature acquisition system effectively prevents the acquisition system from releasing gas under high pressure. and And it can lead to an explosion at high temperatures.

[0040] In this embodiment, when the gas sensor 304 detects gas inside the test chamber 303... and In case of excessively high concentrations, to prevent the acquisition system inside the test chamber 303 from exploding and injuring personnel, the controller 2 first activates the cylinder 402, extending it and causing the arc-shaped protective chamber 403 to move downwards. The arc-shaped protective chamber 403, made of hard iron, effectively protects the test chamber 303 from explosion. Once the arc-shaped protective chamber 403 moves the sealing ring 409 downwards into the slot 302, the arc-shaped protective chamber 403 seals the test chamber 303.

When the temperature acquisition system inside the test chamber 303... and When excessive content leads to spontaneous combustion and explosion, releasing energy and damaging the test chamber 303, the explosive is first extinguished using a fireproof mesh 406. The fireproof mesh 406 is made of copper, which has excellent thermal conductivity, quickly absorbing heat from the flame and lowering the temperature below the ignition point of the combustible material. Furthermore, the copper mesh is flexible. To further reduce the impact force of the explosive, as it spreads outwards, it first impacts multiple compression plates 404. These plates then reset under the elastic action of multiple elastic elements 405, further reducing the impact force of the explosive on the arc-shaped protective chamber 403. Additionally, as the arc-shaped protective chamber 403 moves downwards, it drives the first magnetic connector 407 and the second magnetic connector 408. 08. Moving downwards, after the arc-shaped protective chamber 403 is fixed downwards, the first magnetic connector 407 and the second magnetic connector 408 are exactly aligned with and overlap with the fourth magnetic connector 512 and the third magnetic connector 503, respectively. This achieves the connection between the first magnetic connector 407 and the fourth magnetic connector 512, and also the connection between the second magnetic connector 408 and the third magnetic connector 503. The magnetic connector body can automatically connect when the outer surfaces align, and connect the originally sealed pipeline. The core relies on the synergistic effect of the magnetic positioning and sealing structure design and the valve core linkage mechanism. Strong magnets with opposite polarities are built into both ends of the magnetic connector body. When the two ends are close together, the attraction force of opposite polarities of the magnets will automatically connect the male and female connectors. Precise alignment of the interfaces ensures the central axis of the pipe connections coincides, laying the foundation for subsequent connection. When the two ends of the magnetic connector are separated, each achieves internal sealing of the pipe through an independent sealing component to prevent fluid leakage. The pipe outlet of the male or female connector usually has a raised sealing surface, which, together with the elastic seal, fits tightly under its own pressure, blocking the flow of fluid inside the pipe to the outside. When the two ends are magnetically attracted and connected, the sealing surfaces of the male and female connectors fit tightly together, forming a unified sealed cavity. At this time, the original independent seals are integrated, preventing fluid leakage to the outside and ensuring that fluid can only flow between the two pipes. When an explosion occurs inside the test chamber 303, causing damage to the test chamber 303, the gas generated by the explosion flows through the gas pipe 50. 2. The gas enters the interior of cavity 506. The fire extinguishing chamber 504 is made of fiberglass, which has excellent fire resistance, high strength, and good flexibility, preventing ignition sources from the explosion from entering cavity 506. After the gas from the explosion enters cavity 506, large dust particles fall to the top of baffle 507 under their own gravity. The remaining gas continues to move upwards through perforated plate 509 and enters the flow pipe 508. Simultaneously, temperature sensor 520 is activated to detect the temperature inside flow pipe 508. After the gas enters the threaded pipe 511 through flow pipe 508, the layered rotation within the threaded pipe 511 increases the contact area between the threaded pipe 511 and the outside environment. At this point, the first delivery pump 517 can be activated.The system draws liquid nitrogen into the liquid nitrogen tank 514 via pipe 518. The liquid nitrogen then enters the hollow tube 513 through conduit 519, cooling the high-temperature gas inside the threaded tube 511. The cooled gas then flows back into the arc-shaped protective chamber 403 through the threaded tube 511. Simultaneously, the liquid nitrogen entering the hollow tube 513 flows back into the liquid nitrogen tank 514 through cooling pipe 516. At the same time, the semiconductor cooling chip 515 is activated to further cool the liquid nitrogen inside the tank 514. The cold side of the semiconductor cooling chip 515 faces the outer wall of the liquid nitrogen tank 514. The working principle of the semiconductor cooling chip 515 is a mature existing technology and will not be described in detail here. When the temperature sensor 520 detects that the temperature inside the flow pipe 508 has reached the required value, the gas temperature inside the arc-shaped protective chamber 403 has dropped to the required value, preventing further physical harm to personnel. This solves the problem of explosions during pressure testing in existing automatic electrical temperature acquisition systems, which can endanger the personal safety of personnel.

[0041] like Figures 11-12 As shown, the recycling component 6 includes a recycling pipe 601, one end of which is fixedly inserted into the interior of the flow pipe 508. A solenoid valve body 602 is provided on the outer surface of the recycling pipe 601. The bottom end of the recycling pipe 601 is fixedly connected to the disinfection chamber 603. An air pump 605 is provided on the top of the support block 1. An air inlet pipe 604 is fixedly connected to the input end of the air pump 605. The top end of the air inlet pipe 604 is fixedly connected to the interior of the disinfection chamber 603. An air outlet pipe 606 is fixedly connected to the output end of the air pump 605. A recycling chamber 607 is provided on the top of the support block 1. One end of the air outlet pipe 606 is fixedly inserted into the interior of the recycling chamber 607.

[0042] In this embodiment, when the temperature sensor 520 detects that the temperature inside the flow pipe 508 has reached the required value, the one-way solenoid valve 510 can be closed. The one-way solenoid valve 510 is a switching element that uses electromagnetic force to control the unidirectional flow of fluid. When energized, the electromagnetic coil generates electromagnetic force to attract the valve core, opening the valve and allowing fluid to pass through. When de-energized, the spring force pushes the valve core back to the valve seat, closing the valve and preventing fluid backflow. The one-way solenoid valve 510 also prevents gas backflow. Opening the solenoid valve body 602 simultaneously starts the gas pump 605, driving the recovery pipe 601 to draw gas into the arc-shaped protective chamber 403. After the gas enters the disinfection chamber 603 through the recovery pipe 601, it is filtered by the ion exchange resin installed inside the disinfection chamber 603 to remove toxic gases. Ion exchange resins utilize the ion exchange capacity of their functional groups, combined with the chemical properties of toxic gases, to capture gases. When ionized toxic ions come into contact with the ion exchange resin, the exchangeable ions on the resin's functional groups undergo an equivalent exchange with the toxic ions, fixing the toxic ions onto the resin. Simultaneously, the ions originally carried by the resin are released, and the gas is converted into ions using the solubility and ionization of the gas. Then, through the directional exchange reaction between the resin's functional groups and the toxic ions, the gas is captured and purified. The filtered gas enters the recovery chamber 607 through the inlet pipe 604 and the outlet pipe 606 for recycling and reprocessing until all the toxic gas in the arc-shaped protective chamber 403 is absorbed, thereby effectively preventing the harm of toxic gases generated by an explosion to personnel.

[0043] The usage and working principle of this device are as follows: When performing a withstand voltage test on a self-powered temperature acquisition system used for connectors, first place the acquisition system to be measured on the top of the operating table 314 and fix it with an external positioning device. Then, activate the electric push rod 311 via the controller 2 to extend it, causing the connecting block 312 to move forward until it is inserted into the positioning buckle 313. Once the connecting block 312 is inserted into the positioning buckle 313, activate the drive motor 307 to rotate the drive shaft 308, which in turn rotates the drive gear 309, causing the driven gear 310 to rotate, which in turn rotates the electric push rod 311. This connects the connecting block 312 and the positioning buckle 313, allowing the electric push rod 311 to move the operating table 314 into the test chamber 303 until its outer surface is in complete contact with the inner wall of the test chamber 303. During this forward movement, the operating table 314 also moves the four rotating bolts 325 forward until they are inserted into their corresponding threaded holes 326. The operator can then manually rotate the four bolts 325 with a screwdriver until they are fully inserted into the deepest part of their respective threaded holes 326, thus securing the operating table 314 and placing the self-powered temperature acquisition system. The drive motor 307 can then be restarted to rotate the electric push rod 311 in the opposite direction. Then, the electric actuator 311 can be restarted to move the connecting block 312 out of the positioning buckle 313. After the self-powered temperature acquisition system is placed in the test chamber 303, the exhaust pump 319 is started first, driving the connecting pipe 320 to draw gas into the test chamber 303, and the result is displayed by the pressure sensor 305. When the pressure sensor 305 detects that the test chamber 303 is at a certain pressure value, it indicates that the air in the test chamber 303 has been emptied. Then, the exhaust pump 319 can be turned off by the controller 2, and the second delivery pump 321 is started at the same time, driving the delivery pipe 324 to deliver gas. Argon gas, an inert gas, is drawn from inside tank 323 and enters test chamber 303 through drainage pipe 322, creating high pressure inside test chamber 303. This pressure is displayed by pressure sensor 305. When pressure sensor 305 detects that the pressure inside test chamber 303 reaches a certain value, the second delivery pump 321 is shut off, maintaining that pressure value inside test chamber 303 for a certain period. Simultaneously, gas sensor 304 is activated to detect the presence of oxygen or hydrogen inside test chamber 303 to prevent explosion. and The content of During this process, to prevent an explosion inside the test chamber 303, the controller 2 opens the control valve 316 to release a portion of the combustible gas inside the test chamber 303. Simultaneously, the second delivery pump 321 is restarted to continue supplying argon gas into the test chamber 303, thus replacing the gas inside. This continues until the gas sensor 304 detects that the content of combustible and oxidizing gases inside the test chamber 303 reaches the standard value. and When the content is too high, the controller 2 first activates the cylinder 402, causing it to extend and move the arc-shaped protective chamber 403 downwards. When the arc-shaped protective chamber 403 moves the sealing ring 409 downwards into the slot 302, the arc-shaped protective chamber 403 seals the test chamber 303. Furthermore, during the downward movement of the arc-shaped protective chamber 403, the first magnetic connector 407 and the second magnetic connector 408 move downwards. After the arc-shaped protective chamber 403 is fixed downwards, the first magnetic connector 407 and the second magnetic connector 408 are directly opposite and overlap the fourth magnetic connector 512 and the third magnetic connector 503, respectively. This achieves the connection between the first magnetic connector 407 and the fourth magnetic connector 512, and also the connection between the second magnetic connector 408 and the third magnetic connector 503. When the temperature acquisition system inside the test chamber 303... and When excessive content leads to spontaneous combustion and explosion, releasing energy and damaging the test chamber 303, the explosive is first extinguished through the fireproof mesh 406. The fireproof mesh 406 is made of copper. As the explosive spreads, it first impacts multiple compression plates 404, which are then reset by the elasticity of multiple elastic elements 405, further reducing the impact force of the explosive on the arc-shaped protective chamber 403. When an explosion occurs inside the test chamber 303, damaging it, the gas produced by the explosion enters the interior of the cavity 506 through the gas pipe 502. The fire extinguishing chamber 504 is made of fiberglass. After the gas enters the cavity 506, large particles... Dust particles fall to the top of baffle 507 under their own gravity, while the remaining gas continues to move upward through perforated plate 509 and enters the interior of flow pipe 508. Simultaneously, temperature sensor 520 is activated to detect the temperature inside flow pipe 508. After the gas enters the threaded pipe 511 through flow pipe 508, the layered rotation within the threaded pipe 511 increases the contact area between the threaded pipe 511 and the outside environment. At this point, the first delivery pump 517 can be activated, driving pipe 518 to draw liquid nitrogen into liquid nitrogen tank 514. The liquid nitrogen enters the hollow tube 513 through conduit 519, cooling the high-temperature gas inside threaded pipe 511. The cooled gas then flows back through threaded pipe 511 to the interior of arc-shaped protective chamber 403. At this time, the liquid nitrogen entering the hollow tube 513 continues to flow back into the liquid nitrogen tank 514 through the cooling pipe 516. Simultaneously, the semiconductor cooling chip 515 is activated to continue cooling the liquid nitrogen in the liquid nitrogen tank 514. The cold side of the semiconductor cooling chip 515 faces the outer wall of the liquid nitrogen tank 514. When the temperature sensor 520 detects that the temperature in the flow pipe 508 has reached the required value, that is, when the gas temperature in the surface arc-shaped protective chamber 403 drops to the required value, the one-way solenoid valve 510 can be closed, the solenoid valve body 602 can be opened, and the gas pump 605 can be activated to drive the recovery pipe 601 to draw gas into the arc-shaped protective chamber 403. The gas flows through the recovery pipe 601. After entering the disinfection chamber 603, the toxic gases in the gas are filtered by the ion exchange resin installed in the disinfection chamber 603. The filtered gas enters the recovery chamber 607 through the inlet pipe 604 and the outlet pipe 606 for recycling and reprocessing until all the toxic gases in the arc-shaped protective chamber 403 are absorbed. The controller 2 is electrically connected to the gas sensor 304, pressure sensor 305, drive motor 307, electric actuator 311, control valve 316, exhaust pump 319, second delivery pump 321, cylinder 402, servo motor 505, one-way solenoid valve 510, semiconductor cooling chip 515, first delivery pump 517, temperature sensor 520, solenoid valve body 602 and gas delivery pump 605.
