Description

Technical Field

[0001] This invention relates to the field of cable testing technology, and in particular to a special cable withstand voltage testing device. Background Technology

[0002] Special cables are one of many types of cables. Compared with ordinary cables, they have excellent performance. In order to ensure the safety of cable use, strict voltage withstand tests are required before the cables leave the factory.

[0003] A search revealed that patent application number CN202010269703.X discloses a device and method for testing cable withstand voltage. Before placing the cable into the testing water tank, the conductor block is slid to one end near the threading ring, while leaving enough length for the cable to extend outside the testing water tank. The cable will then be wound around the winding roller, thus preventing the cable from becoming tangled.

[0004] The cable production environment contains a lot of dust, solder particles, and fine copper wires. These impurities entering the constant-temperature water can cause deviations in the cable withstand voltage test. The aforementioned devices immerse the cable in constant-temperature water for a long time and lack the ability to clean the impurities that have entered the water. Therefore, there is a need for a device that can improve the thoroughness of cleaning the immersion water used for cable withstand voltage testing, reduce the impurity content in the immersion water, reduce the impact of dust, solder particles, and fine copper wires on the cable withstand voltage test, and facilitate the collection of impurities. Summary of the Invention

[0013] Preferably, the air supply assembly includes an inclined pipe fixedly connected to the inner wall of the inclined groove, a long plate fixedly connected between the two sides of the inner wall of the inclined pipe, a plurality of fan blades rotatably connected to one side of the long plate, a first motor for driving the fan blades to rotate fixedly connected to one side of the long plate, and a belt for transmission connection between the first motor and the fan blades.

[0014] Preferably, the lifting assembly includes a longitudinal frame with one end movably penetrating through the arc-shaped plate, a second motor is fixedly connected to the top inner side of the longitudinal frame, and a threaded rod with one end movably penetrating through the arc-shaped plate is provided at the output end of the second motor.

[0015] Preferably, the top of the side plate is provided with a metal plate that extends through the side plate at one end, and a plurality of arc-shaped heat-conducting plates are fixedly connected to the top of the metal plate, and a heat dissipation fin is fixedly connected to one side of the metal plate to accelerate the transfer of its surface heat to the water.

[0016] Preferably, the longitudinal frame is fitted with a sleeve that is fixed to the arc-shaped plate. A longitudinal plate is fixedly connected to one side of the sleeve, a circular plate is fixedly connected to the side of the longitudinal plate away from the sleeve, a central column is fixedly connected to the side of the circular plate away from the longitudinal plate, and a plurality of push plates are slidably connected to one side of the circular plate.

[0017] Preferably, a slider corresponding to the push plate is slidably connected to one side of the circular plate, a crossbar is fixedly connected to the side of the slider away from the circular plate, and an elastic sheet is fixedly connected between the slider and the circular plate.

[0018] Preferably, the top of the soaking tank is fitted with a lifting frame, and a horizontal groove is opened on one side of the lifting frame to pass through the lifting frame. A second spring is fixedly connected between the top of the soaking tank and the lifting frame, and multiple clamps for clamping the two ends of the cable are installed on the top of the lifting frame.

[0019] Compared with the prior art, the present invention provides a special cable withstand voltage testing device, which has the following beneficial effects:

[0020] 1. The present invention uses an arc-shaped plate to descend and compress the water inside the soaking tank below. Water at different heights passes through the drainage holes on the arc-shaped plate in sequence and then through the collection component. After passing through the collection component, the water flows away. Impurities in the water are blocked and retained inside the collection component. This can clean the impurities in the water inside the soaking tank layer by layer, improve the thoroughness of cleaning the soaking water for cable withstand voltage testing, reduce the impurity content in the cable soaking water, reduce the impact of dust, solder particles and fine copper wires and other debris on cable withstand voltage testing, and at the same time facilitate the collection of impurities.

[0021] 2. In this invention, water impacts the elastic plate on the arc plate, pushing the elastic plate downward and bending it, which in turn causes the inclined plate and the net cage to descend. This can change the position of the water impacting the net cage by utilizing the change in the water flow impact force, while improving the firmness of the net cage connection. It can also collect impurities in the water at different positions in the net cage, preventing impurities from clogging the feed inlet of the net cage, and reducing the difficulty of disassembling the net cage to clean the impurities inside.

[0022] 3. The electric heating plate of this invention comes into contact with water at different heights, heating the water at different heights, which improves the uniformity of water heating inside the soaking pool. After the water flows above the arc-shaped plate, it absorbs the heat on the upper surface of the arc-shaped plate, reducing the temperature of the upper surface of the arc-shaped plate due to the electric heating plate. At the same time, it heats the water above the arc-shaped plate again, reducing the rate at which the water temperature drops after flowing above the arc-shaped plate, and preventing the safety hazards caused by the arc-shaped plate being heated to an excessively high temperature by the electric heating plate.

[0023] 4. In this invention, after the water passes through the arc-shaped plate, it flows from the drainage groove on one side of the guide block towards the collection component. This can guide the water flow to accelerate along the surface of the arc-shaped plate, wash away impurities on the surface of the arc-shaped plate, and guide the impurities to flow into the collection component along with the water, thereby improving the cleanliness of the surface of the arc-shaped plate.

[0024] 5. The first motor of this invention drives the fan blades to rotate via a belt, drying the arc-shaped plate and special cable that are raised above the water. This reduces the drying time required for the arc-shaped plate and special cable after the withstand voltage test. At the same time, an air curtain is formed at a higher position in the soaking tank, preventing the heat of the warm water inside the soaking tank from dissipating upwards. This helps to keep the warm water inside the soaking tank warm and also reduces the possibility of workers being burned by the hot air inside the soaking tank or by the arc-shaped plate heated by the electric heating plate.

[0038] Example 1

[0039] Reference Figures 1-5 A special cable withstand voltage testing device includes an immersion tank 1, a support plate 2 fixedly connected to one side of the immersion tank 1, and a withstand voltage tester 3 for testing the withstand voltage of the cable fixedly connected to the top of the support plate 2. A cleaning component 4 for cleaning internal impurities is installed inside the immersion tank 1. Warm water is added to the immersion tank 1, and the water temperature inside the immersion tank 1 is kept constant. The special cable to be tested is wound up and immersed in the warm water inside the immersion tank 1. Both ends of the special cable are fixed outside the immersion tank 1. Dust, solder particles, and fine copper wires on the surface of the special cable fall into the warm water. The cleaning component 4 cleans the impurities in the warm water inside the immersion tank 1. The withstand voltage tester 3 performs withstand voltage testing on the special cable. After the test is completed, the special cable is removed from the immersion tank 1. This device can automatically clean impurities in the water inside the immersion tank 1 during the cable withstand voltage test, reducing the impact of impurities on the withstand voltage test of the special cable.

[0040] The cleaning component 4 includes an arc-shaped plate 41 that is slidably connected to the inner wall of the soaking tank 1. Both ends of the arc-shaped plate 41 are fixedly connected to side plates 42 that slide along the inner wall of the soaking tank 1. A lifting component 43 is installed at the bottom inner side of the soaking tank 1 to move the arc-shaped plate 41 up and down. Multiple drainage holes are provided at the top of the arc-shaped plate 41. Two collection components 44 are installed at the top of the arc-shaped plate 41 to collect impurities inside the soaking tank 1. After the special cable is wound, both ends are moved to the outside of the soaking tank 1, and then the middle part of the winding is placed on the arc-shaped plate 41. Water at a suitable temperature is added to the soaking tank 1. The lifting component 43 lowers the arc-shaped plate 41 to the bottom. The side plate 42 slides against the inner wall of the soaking tank 1 throughout the lifting and lowering process of the arc-shaped plate 41 to prevent it from swaying. As the arc-shaped plate 41 descends, it compresses the water inside the soaking tank 1 below. The water below flows through the drain holes on the arc-shaped plate 41 to the top of the plate. The water above the plate flows along its surface to the collecting component 44, where it flows away. Impurities are blocked and retained inside the collection component 44. Water at different heights then passes through the drainage holes on the arc-shaped plate 41 and then through the collection component 44, thus cleaning impurities layer by layer from the water inside the soaking tank 1. This improves the thoroughness of cleaning the soaking water for cable withstand voltage testing, reduces the impurity content in the cable soaking water, and minimizes the impact of dust, solder particles, and fine copper wires on the cable withstand voltage test. It also facilitates the collection of impurities. Finally, the special cable on the arc-shaped plate 41 is immersed in the warm water inside the soaking tank 1, and its withstand voltage is tested. Tester 3 performs withstand voltage tests on special cables. After the special cables in the soaking tank 1 have completed the withstand voltage test, the lifting component 43 drives the arc plate 41 to gradually rise. The water above the arc plate 41 flows through the water leakage holes on the arc plate 41 to the bottom of the arc plate 41. Finally, the arc plate 41 and the special cables above it move to the top of the warm water inside the soaking tank 1. The staff removes the special cables from the arc plate 41 and then places the cables that need to be tested for withstand voltage on the arc plate 41 again. By repeating the above process, the cables can be continuously tested for withstand voltage.

[0041] The collecting component 44 includes an elastic plate 441 fixedly connected to the top of the arc-shaped plate 41. An inclined plate 442, with one end extending movably into the top of the elastic plate 441, is provided on the top of the elastic plate 441. A plurality of limiting posts 443, each with one end movably penetrating through the elastic plate 441, are provided on one side of the inclined plate 442. A mesh cage 444 is fixedly connected to the end of the inclined plate 442 away from the elastic plate 441. An inlet is provided on the side of the mesh cage 444 closest to the inclined plate 442. When water inside the soaking tank 1 passes through the drainage holes on the arc-shaped plate 41, the water on the arc-shaped plate 41 flows along the surface of the arc-shaped plate 41 towards the elastic plate 441, and the water on the arc-shaped plate 41... After the elastic plate 441 is struck, it is pushed downwards and bent, which in turn causes the inclined plate 442 and the mesh cage 444 to descend. Due to the push of the water flow, the inclined plate 442 adheres more tightly to the elastic plate 441. The limiting post 443 prevents the inclined plate 442 from slipping off the elastic plate 441. The thrust of the water flow makes the connection between the inclined plate 442 and the mesh cage 444 and the elastic plate 441 more secure. After the mesh cage 444 descends with the inclined plate 442, the angle between its feed inlet and the elastic plate 441 and the inclined plate 442 is larger, and the water flowing along the arc plate 41 onto the elastic plate 441 and the inclined plate 442 can more easily flow into the mesh cage. Inside the mesh cage 444, impurities enter with the water and are blocked by the cage, remaining on its inner wall. As the water flow speed changes, the impact of the water flow on the elastic plate 441 causes the mesh cage 444 to rotate at different angles. Impurities in the water impact different locations on the inner wall of the mesh cage 444, eventually settling at different points on the inner wall as the water flow changes, until the water flow no longer impacts the elastic plate 441. Due to its elasticity, the elastic plate 441 drives the tilting plate 442 and the mesh cage 444 to rotate upwards, increasing the height of the mesh cage 444. When it is necessary to clean the impurities inside the mesh cage 444... During the process, the operator only needs to move the mesh cage 444 upwards. The mesh cage 444 causes the inclined plate 442 and the limiting post 443 to disengage from the elastic plate 441. After removing the mesh cage 444 from the elastic plate 441, the impurities inside the mesh cage 444 are cleaned. Finally, the mesh cage 444 is placed back on the elastic plate 441. This method can change the position of the water impact mesh cage 444 by utilizing the change in the water flow impact force, while improving the firmness of the mesh cage 444 connection. It collects impurities in the water at different positions of the mesh cage 444, preventing impurities from clogging the feed inlet of the mesh cage 444, and also reducing the difficulty of disassembling the mesh cage 444 to clean the impurities inside.

[0042] Multiple heating plates 5 are fixedly connected to the bottom of the arc-shaped plate 41. A controller is installed on one side of the soaking pool 1. The heating plates 5 are electrically connected to the controller. The operator controls the heating plates 5 to heat the water inside the soaking pool 1 through the controller, so that the water inside the soaking pool 1 is kept at a constant temperature. During the process of the lifting component 43 driving the arc-shaped plate 41 to descend, the heating plates 5 come into contact with water at different heights and heat the water at different heights, which improves the uniformity of heating the water inside the soaking pool 1. When the water below the arc-shaped plate 41 flows through the water leakage hole on the arc-shaped plate 41 to the top of the arc-shaped plate 41, the water absorbs the heat on the upper surface of the arc-shaped plate 41, reducing the temperature of the upper surface of the arc-shaped plate 41 that has been raised by the heating plates 5. At the same time, it raises the temperature of the water above the arc-shaped plate 41 again, reducing the rate at which the water temperature drops after flowing to the top of the arc-shaped plate 41, and preventing the arc-shaped plate 41 from being heated to an excessively high temperature by the heating plates 5, which could pose a safety hazard.

[0043] The lifting assembly 43 includes a longitudinal frame 431 that movably passes through the arc-shaped plate 41 at one end. A second motor 432 is fixedly connected to the top inner side of the longitudinal frame 431. The output end of the second motor 432 is provided with a threaded rod 433 that movably passes through the arc-shaped plate 41 at one end. When the arc-shaped plate 41 needs to be raised, the second motor 432 drives the threaded rod 433 to rotate, thereby raising the arc-shaped plate 41. When the arc-shaped plate 41 needs to be lowered, the second motor 432 rotates in the opposite direction, thereby lowering the arc-shaped plate 41 through the threaded rod 433. The height of the arc-shaped plate 41 can be adjusted as needed.

[0044] Example 2

[0045] like Figures 1-8 As shown, this embodiment is basically the same as embodiment 1. Preferably, a plurality of guide blocks 6 corresponding to the drain holes are fixedly connected to the top of the arc plate 41. A drainage groove communicating with the drain hole is opened on the side of the guide block 6 away from the lifting component 43. Both sides of the guide block 6 are arc surfaces. The inner diameter of the drainage groove is smallest at the end away from the lifting component 43. During the descent of the arc plate 41, the water below the arc plate 41 enters the interior of the guide block 6 through the drain hole on the arc plate 41, and then flows from the drainage groove on one side of the guide block 6 towards the collection component 44. The inner radial direction of the water tank collecting component 44 gradually decreases, and the speed of water flow inside the drainage tank gradually increases. Finally, the water inside the drainage tank impacts the surface of the arc plate 41 at a faster speed and flows along the surface of the arc plate 41 towards the collecting component 44. The arc surfaces on both sides of the guide block 6 reduce the obstruction effect on the water on the arc plate 41, and can guide the water flow to accelerate along the surface of the arc plate 41, wash away impurities on the surface of the arc plate 41, and guide the impurities to flow along the water into the collecting component 44, thereby improving the cleanliness of the surface of the arc plate 41.

[0046] Both sides of the soaking tank 1 are equipped with air supply components 7 for blowing air into it. Inclined slots for installing the air supply components 7 are provided on both sides of the soaking tank 1. The air supply component 7 includes an inclined pipe 71 fixedly connected to the inner wall of the inclined slot. A long plate 72 is fixedly connected between the two sides of the inner wall of the inclined pipe 71. Multiple fan blades 73 are rotatably connected to one side of the long plate 72. A first motor 74 for driving the fan blades 73 to rotate is fixedly connected to one side of the long plate 72. A belt 75 is connected between the first motor 74 and the fan blades 73, and the first motor 74 drives the fan blades 73 to rotate via the belt 75. The air continuously blows from outside the soaking tank 1 into the tank, drying the arc plate 41 and special cable that rise above the water. This reduces the drying time required after the withstand voltage test. At the same time, an air curtain is formed at a higher position in the soaking tank 1, preventing the heat of the warm water inside the tank from dissipating upwards. This helps to keep the warm water inside the tank and also reminds workers to move their limbs into the hot area below, reducing the possibility of burns from the heat inside the tank or from the arc plate 41 heated by the electric heating plate 5.

[0047] A metal plate 8 is provided on the top of the side plate 42, with one end penetrating the side plate 42. Multiple arc-shaped heat-conducting plates 9 are fixedly connected to the top of the metal plate 8. A heat dissipation fin 10 is fixedly connected to one side of the metal plate 8 to accelerate the transfer of its surface heat to the water. The heat that remains inside the immersion tank 1 after being blocked by the air supply assembly 7 is absorbed by the arc-shaped heat-conducting plates 9, and then transferred to the water below the arc plate 41 through the metal plate 8 and the heat dissipation fin 10. This can slow down the rate at which the water temperature inside the immersion tank 1 decreases after the electric heating plate 5 stops heating. During the heating process of the electric heating plate 5, the heat is retained inside the immersion tank 1 by the air supply assembly 7. Therefore, the temperature of the water below the arc plate 41 is transferred to the air above the arc plate 41 through the heat dissipation fins, the metal plate 8 and the arc-shaped heat-conducting plates 9, and the overall temperature inside the immersion tank 1 is maintained at a certain level. This will not cause the water temperature below the arc plate 41 to drop and affect the withstand voltage test of the special cable immersed in it.

[0048] Example 3

[0049] like Figures 1-9As shown, this embodiment is basically the same as embodiment 1. Preferably, a sleeve 11 fixed to the arc plate 41 is sleeved on the outside of the longitudinal frame 431. A longitudinal plate 12 is fixedly connected to one side of the sleeve 11. A circular plate 13 is fixedly connected to the side of the longitudinal plate 12 away from the sleeve 11. A middle column 14 is fixedly connected to the side of the circular plate 13 away from the longitudinal plate 12. A plurality of push plates 15 are slidably connected to one side of the circular plate 13. A first spring 16 is fixedly connected between the push plates 15 and the middle column 14. A slider 17 corresponding to the push plates 15 is slidably connected to one side of the circular plate 13. A crossbar 18 is fixedly connected to the side of the slider 17 away from the circular plate 13. An elastic sheet 19 is fixedly connected between the slider 17 and the circular plate 13. When a special cable roll needs to be tested for withstand voltage... Afterwards, move both ends of the special cable to the outside of the soaking tank 1. The worker squeezes the push plate 15 towards the middle. The push plate 15 compresses and contracts the first spring 16, gradually approaching the middle column 14. At this time, the gap between the push plate 15 and the crossbar 18 widens. Then, the wound special cable is placed on the outside of the push plate 15. The push plate 15 is released, and the first spring 16 pushes the push plate 15 to push the special cable outwards until the outside of the special cable is blocked by the crossbar 18. The push plate 15 continues to push the special cable to squeeze the crossbar 18 until the crossbar 18 drives the slider 17 to move and squeezes and bends the elastic sheet 19. This can fix cables with different winding inner diameters, prevent the cable from loosening during the withstand voltage test, and improve the stability of the cable position during the withstand voltage test.

[0050] Example 4

[0051] like Figures 1-10 As shown, this embodiment is basically the same as embodiment 3. Preferably, a lifting frame 20 is fitted on the top of the soaking tank 1. A horizontal groove is opened on one side of the lifting frame 20 to pass through the lifting frame 20. A second spring 21 is fixedly connected between the top of the soaking tank 1 and the lifting frame 20. Multiple clamps 22 for clamping the two ends of the cable are installed on the top of the lifting frame 20. After the coiled part in the middle of the cable is fitted outside the push plate 15, the two ends of the cable are respectively placed into different clamps 22 for fixation. When the arc plate 41 descends, the arc plate 41 drives the circular plate 13 and the special cable fixed above it to descend. The two ends of the special cable pull the clamps 22 and the lifting frame 20 to descend, squeezing and contracting the second spring 21 until the lifting frame 20 descends to the lowest point and is blocked by the soaking tank 1. During this process, the two ends of the cable are always stretched and taut, which can keep the cable stretched and taut for a long time to facilitate withstand voltage testing. At the same time, the cable is calibrated during the process of stretching and taut, reducing the possibility of cable winding and tangling.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
