Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and in particular to a cable detection device. Background Art

[0002] Cables play a vital role in various infrastructures in modern society. They are used in power transmission, communication systems, data processing facilities and other fields. The structure of the cable usually includes the core conductive part and the outer insulation layer. Their integrity is crucial to ensure the reliable operation and overall safety of the system. Therefore, accurate cable integrity testing has become an important part of maintenance work. In traditional cable detection methods, the cable is usually immersed in a conductive liquid to test whether it has defects. By running power through the cable and testing whether the surrounding liquid is charged, the insulation performance of the cable and whether the outer sheath is damaged can be judged. However, this method has certain limitations when dealing with minor damage. When the damage to the cable is small and not enough for the liquid to penetrate naturally, it may lead to inaccurate test results.

[0003] In the prior art, in order to allow the liquid to penetrate sufficiently into the damaged part of the cable, some detection systems have introduced a boosting component to apply pressure to the conductive liquid. However, this boosting may have an adverse effect on the flexible outer skin of the cable. Under the action of pressure, the flexible outer skin of the cable may be further compressed, which may enhance the sealing effect of the damaged part, making it more difficult for the conductive liquid to enter the damaged area, which will still affect the detection results and cannot guarantee the accuracy of the detection.

The cable is clamped and conveyed by the V-shaped depression, which can reduce the contact area between the first conveying wheel 3 and the second conveying wheel 6 and the cable, and ensure a certain friction force to convey the cable normally.

[0038] A lifting frame 4 is provided at the bottom of the linkage plate 7. The lifting frame 4 is slidably connected to the base plate 2. The bottom of the lifting frame 4 is located below the base plate 2 and is connected to a support plate 13. A first internal threaded sleeve 9 is rotatably installed in the support plate 13. The first internal threaded sleeve 9 is internally threadedly connected to a first screw rod 8. The first screw rod 8 is rotatably connected to the bottom surface of the base plate 2.

[0039] In this embodiment, a lifting frame 4 is provided between the linkage plate 7 and the bottom plate 2. The bottom of the lifting frame 4 is slidably connected to the bottom plate 2, so that the distance between the first conveying wheel 3 and the second conveying wheel 6 can be adjusted to facilitate the conveyance of cables with different outer diameters.

[0040] A first motor 12 is fixedly mounted at the bottom of the base plate 2 , and a first synchronous pulley 10 is fixedly mounted on the output shaft end of the first motor 12 and the surface of the first internal threaded sleeve 9 .

Since one end of the first screw rod 8 is rotatably connected to the lower surface of the bottom plate 2, the first internal threaded sleeve 9 drives the support plate 13 and the lifting frame 4 to rise and fall in the bottom plate 2 during the movement of the surface of the first screw rod 8.

[0042] Hollow shafts 15 and solid rods 16 are symmetrically arranged on both sides of the first conveying wheel 3 and the second conveying wheel 6. The second conveying wheel 6 is rotatably installed in the linkage plate 7 through the hollow shaft 15 and the solid rod 16 respectively. A hollow groove is opened in the second conveying wheel 6, and an electric heating rod 14 is fixedly installed in the hollow groove. The electric wire at one end of the electric heating rod 14 passes through the hollow shaft 15 and extends to the outside of the hollow shaft 15.

[0043] In the present embodiment, the first conveying wheel 3 and the second conveying wheel 6 are both configured as heating wheel structures. Specifically, the first conveying wheel 3 and the second conveying wheel 6 are both configured as hollow structures, and an electric heating rod 14 is arranged in the hollow groove thereof. The hollow shaft 15 is configured as a hollow tube structure for passing through electric wires provided to supply power to the electric heating rod 14 without affecting the rotational conveyance of the first conveying wheel 3 and the second conveying wheel 6. After the first conveying wheel 3 and the second conveying wheel 6 are subjected to heat conduction treatment by the electric heating rod 14, the cables are heated.

[0044] It should be noted that the first conveying wheel 3 and the second conveying wheel 6 are preferably made of metal with high thermal conductivity, so as to achieve: fast and uniform heat conduction to the cable during the process of conveying the cable.

[0045] It should be noted that a motor is transmission-connected at one end of the first conveying wheel 3 and the second conveying wheel 6 to drive the first conveying wheel 3 to rotate, and several groups of first conveying wheels 3 and second conveying wheels 6 are transmission-connected to realize the conveyance of cables.

[0046] A guide assembly that cooperates with the conveying assembly is provided in the detection box 1, and the guide assembly includes an upper guide wheel 22 and a lower guide wheel 24. The upper guide wheel 22 is arranged in the detection box 1 in a liftable manner through a hanger 23. A feed pipe 19 and a first guide pipe 31 are symmetrically provided on both sides of the detection box 1. The first guide pipe 31 is connected to a second guide pipe 33 for blowing air into the cable.

[0047] In this embodiment, when the cable is conveyed to one end of the feed pipe 19 via the first conveying wheel 3 and the second conveying wheel 6, and then enters the interior of the detection box 1 via the feed pipe 19, a guide assembly is provided to guide the movement of the cable in the detection box 1, so that one end of the cable smoothly enters the first guide tube 31, and the conveying is stopped after one end of the cable is flush with the sealing ring 32.

[0048] One end of the hanger 23 is rotatably connected to the second screw rod 25, the surface of the second screw rod 25 is threadedly connected to the second internal threaded sleeve 27, the second internal threaded sleeve 27 is externally transmission-connected to the second motor 26, two groups of fixed rods 39 are fixedly installed in the detection box 1, and fixed frames 38 are connected between the fixed rods 39, and the lower guide wheel 24 is rotatably connected between the two groups of fixed frames 38. Two groups of brackets 17 are symmetrically arranged on the upper surface of the bottom plate 2 at the front and rear ends of the conveying component, and a distance sensor 18 is fixedly installed on the bracket 17, and the distance sensor 18 is electrically connected to the second motor 26.

[0049] In this embodiment, in order to make the guide assembly adapt to cables with different outer diameters and to facilitate the adjustment of the guiding clamping force of the guide assembly on the cable to avoid secondary wear of the cable, a second motor 26 is provided on one side of the hanger 23. Specifically, the second motor 26 is started, and the second internal threaded sleeve 27 is driven by the forward / reverse rotation of the second motor 26. The second screw rod 25 is driven to rotate while moving up and down in the second internal threaded sleeve 27, thereby adjusting the distance between the lower guide wheel 24 and the upper guide wheel 22.

[0050] It should be noted that two groups of distance measuring sensors 18 are symmetrically arranged outside the detection box 1 at the entrance of the feed pipe 19. The distance measuring sensors 18 are used to detect the diameter of the cable, thereby controlling the second motor 26 to control the hanger 23 to drive the upper guide wheel 22 to move, thereby automatically controlling the guide assembly to adapt to cables of different diameters.

[0051] It should be noted that the distance measuring sensor 18 is electrically connected to the first motor 12 and can also electrically control the first motor 12 so that the first conveying wheel 3 and the second conveying wheel 6 automatically adapt to cables of different diameters.

[0052] A first mounting frame 21 is fixedly mounted on one side of the inner wall of the detection box 1 , a signal light 20 is fixedly mounted on the top of the first mounting frame 21 , and the signal light 20 is electrically connected to the conductive liquid in the detection box 1 .

[0053] In this embodiment, a signal light 20 is provided on one side of the detection box 1. The signal light 20 is fixedly mounted on the inner wall of the detection box 1 by a first mounting bracket 21. The signal light 20 is electrically connected to the conductive liquid. If the cable to be detected is damaged, it can be tested whether the surrounding liquid is charged, thereby determining whether the cable is damaged.

[0054] A lifting assembly is arranged between the second guide tube 33 and the detection box 1, and the lifting assembly includes a cylinder 35 fixedly mounted on the upper surface of the cover plate 43, a lifting frame 36 is fixedly mounted on one side of the second guide tube 33, one end of the lifting frame 36 is fixedly mounted on the telescopic rod end of the cylinder 35, an air inlet 34 connected to an external air pump is arranged at one end of the second guide tube 33, and a sealing ring 32 is arranged at the end of the first guide tube 31.

[0055] In this embodiment, a lifting assembly is provided between the second guide tube 33 and the inspection box 1. By connecting the second guide tube 33 for inflation and the first guide tube 31 for guiding the cable to move out of the inspection box 1, the inside of the cable is inflated so that the gas overflows when passing through the damaged position, thereby generating bubbles in the conductive liquid. In this way, during the inspection operation, not only the quality problems of the cable can be detected, but also the specific defects can be determined.

[0056] Specifically, one end of the second guide tube 33 is connected to an air inlet 34, and the air inlet 34 is connected to an external air pump. When one end of the cable is transported to the pipe mouth of the first guide tube 31, the cylinder 35 is started, and the output shaft end of the cylinder 35 pulls the second guide tube 33 downward, so that the second guide tube 33 and the first guide tube 31 are connected by snapping together, and the external air pump is started to inflate the cable, and the two groups of pipes are sealed with a sealing ring 32 to ensure that the gas is completely passed into the cable during inflation, further ensuring the feasibility and accuracy of determining the specific damaged position of the cable under the action of inflation.

[0057] The bottom of the lifting assembly is located in the detection box 1 and is connected to a clamping assembly for squeezing the cable. The clamping assembly includes two sets of clamping rollers 49. A suspension rod 37 is fixedly installed on one side of the bottom of the lifting frame 36. A double-ear frame 44 is fixedly connected to the bottom of the suspension rod 37. A first connecting plate 46 is pinned to the bottom of the double-ear frame 44 through a pin shaft 45. A second connecting plate 47 is pinned to one end of the first connecting plate 46. A third connecting plate 48 is pinned to one end of the second connecting plate 47. The clamping roller 49 is fixedly installed at the bottom of the third connecting plate 48. The pin-connecting shafts of the second connecting plate 47 and the third connecting plate 48 are connected to the bottom of the cover plate 43 through a second mounting frame 50.

[0058] In this embodiment, during the downward movement of the second guide tube 33, the suspension rod 37 is driven downward, thereby driving the first connecting plate 46 downward. After the first connecting plate 46 moves downward, the second connecting plate 47 is pushed away from the suspension rod 37, thereby driving the third connecting plate 48 to move toward the cable, and driving the clamping rollers 49 on both sides to move closer to the cable, thereby squeezing the cable, so that the expansion area of ​​the damaged part of the heated cable is increased during the squeezing process, which better ensures that the gas can be discharged from the damaged position, making the bubbles in the conductive liquid more obvious, thereby ensuring the effectiveness of the detection.

[0059] The defect collection components are symmetrically arranged in the detection box 1 , and the defect collection components include two sets of driving rods 28 . A connecting block 29 is fixedly installed on the surface of the driving rod 28 , and a camera 30 is installed in the connecting block 29 .

[0060] In this embodiment, two groups of cameras 30 are symmetrically arranged above the detection box 1. The cameras 30 can detect bubbles, thereby recording the detection structure in all directions. Through the electrical control system, the records are made in time to avoid incomplete monitoring by the operator.

[0061] A second synchronous pulley 41 is fixedly mounted on one end of the driving rod 28 , a third motor 40 is fixedly mounted on the cover plate 43 , a second synchronous pulley 41 is also fixedly mounted on the output shaft end of the third motor 40 , and the two sets of second synchronous pulleys 41 are connected through a second conveyor belt 42 .

[0062] In this embodiment, a third motor 40 is provided at one end of the driving rod 28 . When the third motor 40 is started, the second synchronous pulley 41 is driven to rotate, and the driving rod 28 is driven to rotate through the second conveyor belt 42 , thereby expanding the acquisition range of the camera 30 .

[0063] In the present invention, one end of the cable is first placed between the first conveying wheel 3 and the second conveying wheel 6, and the motor is started to drive the first conveying wheel 3 and the second conveying wheel 6 to rotate, and the cable is conveyed toward the detection box 1, and the cable enters the detection box 1 through the feed pipe 19;

[0064] Start the distance sensor 18 to measure the outer diameter of the cable, start the first motor 12, and the first motor 12 drives the first synchronous pulley 10 to rotate through the first conveyor belt 11 to the first internal threaded sleeve 9. Since one end of the first screw rod 8 is rotatably connected to the lower surface of the bottom plate 2, the first internal threaded sleeve 9 drives the support plate 13 and the lifting frame 4 to rise and fall in the bottom plate 2 during the movement of the first screw rod 8, so as to adapt to the outer diameter of the cable, control the distance between the first conveying wheel 3 and the second conveying wheel 6, reduce the friction that the first conveying wheel 3 and the second conveying wheel 6 may cause to the cable, and avoid secondary damage to the cable caused by the conveying process as much as possible;

[0065] The electric heating rod 14 is started to heat the first conveying wheel 3 and the second conveying wheel 6, so that the cable is heated during the conveying process. The thermal expansion phenomenon causes the originally tiny and difficult-to-observe cracks or damaged parts inside the cable to be physically expanded, making it easier for the conductive liquid to enter these cracks or damaged parts, thereby improving the accuracy of the detection;

[0066] The cable is continuously transported, and a guide assembly is set to guide the movement of the cable in the detection box 1. The second motor 26 is started, and the second internal threaded sleeve 27 is driven by the forward / reverse rotation of the second motor 26. The second screw rod 25 is driven to rotate while moving up and down in the second internal threaded sleeve 27, thereby adjusting the distance between the lower guide wheel 24 and the upper guide wheel 22, so that one end of the cable can smoothly enter the first guide tube 31, and the transportation is stopped after one end of the cable is flush with the sealing ring 32. If the cable to be detected is damaged, it can be tested whether the surrounding liquid is charged, so as to determine whether the cable is damaged;

[0067] Start the cylinder 35, the output shaft end of the cylinder 35 pulls the second guide tube 33 downward, so that the second guide tube 33 and the first guide tube 31 are connected and connected, start the external air pump to inflate the cable, and use the sealing ring 32 to seal the two sets of pipes to ensure that the gas is completely passed into the cable during inflation, so that the gas overflows when passing through the damaged position, thereby generating bubbles in the conductive liquid, so that during the detection operation, not only the quality problems of the cable can be detected, but also the specific defects can be determined;

[0068] In the process of the second guide tube 33 moving downward, the suspension rod 37 is driven downward, thereby driving the first connecting plate 46 to move downward. After the first connecting plate 46 moves downward, the second connecting plate 47 is pushed away from the suspension rod 37, thereby driving the third connecting plate 48 to move toward the cable, and driving the clamping rollers 49 on both sides to move closer to the cable, thereby squeezing the cable, so that the expansion area of ​​the damaged part of the heated cable is increased during the squeezing process, which better ensures that the gas can be discharged from the damaged position, making the bubbles in the conductive liquid more obvious, thereby ensuring the effectiveness of the detection.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
