Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cable testing technology, and in particular relates to a cable leakage detection device. Background Technology
[0002] Cables are devices used for transmitting electrical energy or information, and are often laid in the air, in the soil, or in the water. In order to ensure the safety of the cables in subsequent use, it is necessary to use a leakage current detector to test the cables for leakage current before use.
[0003] Existing cable leakage detection devices are cumbersome to use and not very practical. For example, the cable leakage detection device shown in the patent publication number CN220509106U requires the cable to be inserted into one end of the through hole and pulled out from the other end during use. This is not only cumbersome to operate, but also only the entire cable can be detected, not just a certain section or a few sections of the cable, resulting in poor flexibility in use.
[0004] Therefore, we propose a cable leakage detection device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to solve the problems of the existing technology being cumbersome to use and having poor practicality, and to propose a cable leakage detection device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cable leakage current detection device includes a detection platform and a top cover hinged to the top of the detection platform. A wire passage cavity is horizontally provided through the top of the detection platform. A detection cavity extends downward from the middle of the wire passage cavity. The detection cavity is filled with conductive liquid, and a detection component for detecting the level of conductive liquid is provided on the inner wall of the detection cavity.
[0008] Rotating rollers are rotatably provided at both ends of the wire passage cavity, and a first pulley is movably provided above the rotating rollers. An adjustment component is provided on the top cover to drive the first pulley to move up and down. A sliding rod is provided through the middle of the top cover and slides up and down, and a second pulley is fixedly installed at the bottom of the sliding rod. A locking component is provided on the top cover to lock the movement of the sliding rod.
[0009] The bottom surface of the top cover is slidably provided with an insertion rod, and the side wall of the wire passage cavity is provided with an insertion hole for inserting the insertion rod. The sliding rod is provided with a first magnet and a second magnet from top to bottom. The end of the insertion rod facing the sliding rod is fixedly connected to a third magnet, and the first magnet and the third magnet repel each other, while the second magnet and the third magnet attract each other.
[0010] Preferably, the locking assembly includes a mounting base fixedly connected to the top surface of the top cover, and the sliding rod is slidably sleeved in the mounting base. A cam that locks the sliding rod by friction is hinged to one side of the mounting base.
[0011] Preferably, the top surface of the sliding rod is fixedly connected to an upper limit block that mates with the mounting base.
[0012] Preferably, a lower limit block is fixedly connected to the side of the bottom of the sliding rod away from the insertion rod.
[0013] Preferably, the top surface of the top cover has a door-shaped mounting bracket that slides up and down on both sides, and the bottom end of the mounting bracket extends into the cable passage cavity. The first pulley is rotatably disposed between the two sides of the bottom end of the mounting bracket. The adjustment component includes a butterfly bolt rotatably disposed on both sides of the top surface of the top cover, and the butterfly bolt thread passes through the top of the mounting bracket.
[0014] Preferably, an auxiliary roller is rotatably connected to the inner wall of the thread-passing cavity between the first pulley and the second pulley.
[0015] In summary, the technical effects and advantages of this utility model are as follows: This cable leakage detection device, through the hinged top cover and detection platform, enables the rapid placement of the cable. A sliding rod, in conjunction with a second pulley, drives the cable downwards and immerses it in the conductive liquid. A first magnet, in conjunction with a third magnet, enables the sliding rod to automatically insert the insertion rod into the socket during the downward pressing process, thereby automatically locking the top cover. A second magnet, in conjunction with a third magnet, enables the insertion rod to automatically disengage from the socket during the sliding rod's reset process. Compared to existing devices, this device avoids the problems of cumbersome use and poor practicality, improving detection efficiency and operational flexibility. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-3 A cable leakage current detection device includes a detection platform 1 and a top cover 2 hinged to the top of the detection platform 1. A cable passage cavity 3 is horizontally provided through the top of the detection platform. A detection cavity 4 extends downward from the middle of the cable passage cavity 3. The detection cavity 4 is filled with a conductive liquid 5, and a detection component 6 for detecting the voltage level of the conductive liquid 5 is provided on the inner wall of the detection cavity 4. The detection component 6 is prior art. When the conductive liquid 5 passes through the cable leakage point, it will cause a voltage level change, and the detection component 6 will detect the leakage current.
[0023] Rotating rollers 7 are provided at both ends of the wire passage cavity 3. A first pulley 8 is movably provided above the rotating rollers 7. An adjustment component is provided on the top cover 2 to drive the first pulley 8 to move up and down. A sliding rod 9 is provided through the middle of the top cover 2 and slides up and down. A second pulley 10 is fixedly installed at the bottom of the sliding rod 9. A locking component is provided on the top cover 2 to lock the movement of the sliding rod 9.
[0024] Reference Figure 3-4 The bottom surface of the top cover 2 is provided with a slidable insertion rod 11. The side wall of the wire passage cavity 3 is provided with an insertion hole 12 for the insertion rod 11 to be inserted. The sliding rod 9 is provided with a first magnet 13 and a second magnet 14 from top to bottom. The end of the insertion rod 11 facing the sliding rod 9 is fixedly connected to a third magnet 15. The first magnet 13 and the third magnet 15 repel each other, while the second magnet 14 and the third magnet 15 attract each other.
[0025] In use, the cable leakage detection device first opens the top cover 2 and places the cable on the two rotating rollers 7 of the cable passage cavity 3. Then, the top cover 2 is closed, and the first pulley 8 is driven downwards by the adjusting component until it contacts the cable. After this, the sliding rod 9 is moved downwards. At this point, the second magnet 14 moves away from the third magnet 15, and the first magnet 13 moves closer to the third magnet 15. The insertion rod 11 moves and inserts into the insertion hole 12. The sliding rod 9 continues to move downwards until the second pulley 10 pushes the cable down and immerses it in the conductive liquid 5. The sliding rod 9 is then locked by the locking component, and leakage detection of the cable can begin. If the cable does not leak, the detection level of the detection component 6 remains unchanged; if the cable leaks, the detection level of the detection component 6 changes when the leakage point passes through the conductive liquid 5, thus detecting the leakage point.
[0026] After the test is completed, the sliding rod 9 is unlocked by the locking component and moved upward until the first magnet 13 moves away from the third magnet 15 and the second magnet 14 moves closer to the third magnet 15. The insertion rod 11 moves and disengages from the insertion hole 12. At this time, the sliding rod 9 is locked by the locking component, thus realizing the reset of the sliding rod 9.
[0027] Reference Figure 1-3 The locking assembly includes a mounting base 16 fixedly connected to the top surface of the top cover 2, and a sliding rod 9 slidingly fitted inside the mounting base 16. A cam 17 is hinged to one side of the mounting base 16, which locks the sliding rod 9 by friction. This locking assembly locks the side wall of the sliding rod 9 by the rotation of the cam 17 in conjunction with friction. The process is simple and efficient.
[0028] Reference Figure 1 , Figure 2 , Figure 4 The top surface of the sliding rod 9 is fixedly connected to an upper limit block 18 that matches the mounting base 16, thereby limiting the movement of the sliding rod 9 to the lowest point and preventing the sliding rod 9 from moving downward and disengaging from the mounting base 16; the bottom end of the sliding rod 9 is fixedly connected to a lower limit block 19 on the side away from the insertion rod 11, thereby limiting the movement of the sliding rod 9 to the highest point and preventing the sliding rod 9 from moving upward and disengaging from the mounting base 16.
[0029] Reference Figure 1-3 The top cover 2 has two sliding, U-shaped mounting brackets 20 on its top surface, with the bottom end of the mounting brackets 20 extending into the cable passage cavity 3. A first pulley 8 is rotatably positioned between the two bottom ends of the mounting bracket 20. The adjustment assembly includes wing bolts 21 rotatably mounted on both sides of the top surface of the top cover 2, with the wing bolts 21 threaded through the top of the mounting bracket 20. This adjustment assembly, through the rotation of the wing bolts 21, drives the mounting bracket 20 to move up and down, and the first sliding bracket moves up and down accordingly for adjustment.
[0030] An auxiliary roller 22 is rotatably connected to the inner wall of the cable passage cavity 3 between the first pulley 8 and the second pulley 10, so as to prevent the cable from being scratched and damaged by the top edge of the detection cavity 4 and improve the practicality of the device.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
