Description

Technical Field

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

[0002] In modern power transmission, cables are key carriers of electrical energy, and the quality of their insulation directly impacts the safe and stable operation of power systems. With the continuous growth of power demand and the increasing complexity of cable applications, higher requirements are being placed on the accuracy, comprehensiveness, and adaptability of cable insulation testing technology.

[0003] Traditional visual inspection methods struggle to fully inspect cable insulation from every angle, and are prone to missing subtle and irregularly distributed surface defects such as ruptures, overlaps, protrusions, depressions, pinholes, cracks, and wrinkles. Furthermore, due to significant ambient light interference, without effective light shielding measures, the image quality captured by the camera is poor, seriously affecting the accuracy of inspection results.

[0004] Existing detection devices lack auxiliary visual detection methods, and existing detection devices can usually only detect a single location or a limited area. It is difficult to quickly adjust the detection angle and direction, cannot meet different detection needs, and the detection efficiency is low.

[0005] Existing testing equipment has poor adaptability to cable lengths. Most clamping devices are fixed in size, making it difficult to flexibly adjust the clamping spacing and position based on cable length. This makes it difficult to achieve stable clamping and transmission for cables of varying lengths, and can easily cause the cable to wobble or shift during testing, impacting the accuracy and stability of subsequent testing steps. Furthermore, when defects are detected in the cable insulation, existing technologies lack effective marking and secondary inspection methods. Even if defects are discovered, they cannot be clearly marked for subsequent processing, and secondary, accurate inspection of the defective area to further confirm the defect is impossible, hindering the analysis and repair of defective cables.

[0017] A method for detecting a cable insulation layer is also provided, comprising the following steps:

[0018] S1: Place the cable on the work platform and start the transmission mechanism. The transmission mechanism adjusts the spacing and position of the clamping transmission rollers according to the cable length through the adaptive adjustment component, stably clamps the cable, and smoothly sends it into the internal detection area of the equipment;

[0019] S2: When the cable enters the visual inspection area, the visual inspection mechanism is turned on. The operator adjusts the position of the inspection camera according to the actual situation of the cable. The ring light source lights up, and three inspection cameras are distributed in a ring at a 120-degree angle around the axis of the cable insulation layer. They quickly and accurately capture images of the cable insulation layer from multiple angles and detect surface defects such as ruptures, overlaps, protrusions, depressions, pinholes, cracks, and wrinkles.

[0020] S3: The cable continues to travel to the interference detection mechanism area, where it activates. The position adjustment assembly drives the rotating ring based on the cable length, synchronously adjusting the positions of multiple sliding mounts so that the interference detection assembly contacts the cable insulation with appropriate pressure. The interference detection assembly rotates with the rotating disk, and the pressure sensor monitors the pressure changes at the contact point, accurately determining the location of insulation defects and completing secondary inspection to verify the visual inspection results.

[0021] S4: If the visual inspection mechanism and the interference detection component detect defects in the cable insulation layer, the marking mechanism starts working, the switching component pushes the paint brush to contact the surface of the cable insulation layer, the paint pipeline is connected to the paint brush, and the interference detection component is rotated as a whole to apply paint to the defective part of the cable. Subsequently, the equipment retracts the marked part to the inspection area of the visual inspection mechanism. The inspection camera again accurately detects the coating mark position, using the light absorption effect of the mark to improve the contrast and further confirm the defect.

[0022] S5: After the test is completed, the transmission mechanism sends the tested cable out of the device, ending the test process.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. When inspecting cable insulation, the present invention uses three inspection cameras arranged at a 120-degree angle, combined with a light shielding device and a ring light source, to capture images of the cable insulation from multiple angles, effectively detecting a variety of surface defects. The interference detection component can be precisely adjusted according to the cable length, accurately determining the defect location through pressure changes. The combination of the two greatly improves the comprehensiveness and accuracy of inspection, avoiding missed detections and misjudgments that can occur with a single inspection method.

[0025] 2. The transmission mechanism's adaptive adjustment assembly flexibly adjusts the spacing and position of the clamping rollers based on cable length. The unique design of the clamping rollers, with a small center diameter and gradually increasing diameters at both ends, enables stable clamping of cables of varying lengths. The position adjustment assembly of the interference detection mechanism simultaneously adjusts multiple sliding mounts to accommodate varying cable lengths, ensuring smooth testing.

[0026] 3. The marking mechanism can promptly apply a mark to the defective area when a defect is detected. The equipment also has a retraction function that can return the marked area to the visual inspection area. The mark absorbs light to increase contrast for secondary accurate inspection, further improving detection reliability and facilitating subsequent processing and analysis of defective cables.

DETAILED DESCRIPTION

[0041] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1-12The cable insulation layer detection device shown is arranged on a work platform 2 and is used to detect the insulation layer of the cable 1. It includes a visual detection mechanism 3, a conflict detection mechanism 4, a marking mechanism 5 and a transmission mechanism 6. The visual detection mechanism 3 includes a first support frame 7, a detection camera 8, an annular light source 9, a first mounting plate 10, a light shield 11 and a light shielding tube 12. The first support frame 7 is installed on the work platform 2. The first mounting plate 10 and the detection camera 8 are each provided with three and distributed in a ring around the axis of the insulation layer of the cable 1. The detection camera 8 is adjustable on the first support frame 7 through the first mounting plate 10. The light shielding tube 12 and the light shield 11 are respectively fixedly mounted on both sides of the first support frame 7. The detection end of the detection camera 8 extends into the light shield 11. The annular light source 9 is fixedly mounted on the light shield. Inside the light mask 11, the interference detection mechanism 4 is located next to the visual detection mechanism 3. The interference detection mechanism 4 includes a second support frame 13, a rotating disk 14, an interference detection component and a position adjustment component. The interference detection component is provided with several groups and is distributed in a ring around the rotating disk 14. The rotating disk 14 is rotatably installed on the second support frame 13. The position adjustment component is installed on the working platform 2 and is transmission-connected with several groups of interference detection components. The marking mechanism 5 includes a paint pipe 15, a brush 16 and a switching component. The brush 16 and the switching component are both installed on one group of interference detection components. The brush 16 and the group of interference detection components are both transmission-connected with the switching component. The paint pipe 15 is connected to the brush 16. The transmission mechanism 6 for transmitting the cable 1 is provided with two groups and is located at both ends of the working platform 2 respectively.

[0043] The cable 1 is placed on the working platform 2, and the transmission mechanism 6 is started to smoothly feed the cable 1 into the equipment. The transmission mechanism 6 can flexibly adjust the clamping and driving mode according to the diameter of the cable 1 to ensure that cables 1 of different specifications can pass through the equipment smoothly for inspection. The visual inspection mechanism 3 is in operation, and the three inspection cameras 8 are distributed in a ring at an angle of 120 degrees around the axis of the insulation layer of the cable 1. According to the actual situation of the cable 1, the operator flexibly adjusts the position of the inspection camera 8 on the first support frame 7 through the first mounting plate 10 to shoot at the best angle and distance. The annular light source 9 lights up in the light shield 11, providing stable light, and the light shield 11 and the light shield tube 12 block external stray light. The inspection camera 8 quickly and accurately captures the image of the insulation layer of the cable 1 from multiple angles, and efficiently detects surface defects such as ruptures, overlaps, protrusions, depressions, pinholes, cracks, wrinkles, etc., greatly improving the comprehensiveness and accuracy of inspection.

[0044] The interference detection mechanism 4 is located next to the visual detection mechanism 3. As an auxiliary method to assist the visual detection mechanism 3, after the optical detection, a secondary detection is performed based on the results of the optical detection, and actual contact can be made with the area where defects may exist, so as to accurately judge the accuracy of the detection results. The rotating disk 14 on the second support frame 13 rotates, driving the several groups of interference detection components distributed around it to rotate. The position adjustment component synchronously adjusts each group of interference detection components according to the diameter of the cable 1 to contact the insulation layer of the cable 1 with appropriate pressure. When there is a defect in the insulation layer, the pressure at the contact part changes, and the defect position is quickly detected. At the same time, the detection angle and orientation can be quickly adjusted to meet different detection needs.

[0045] The marking mechanism 5 comes into play when the visual inspection mechanism 3 and the interference detection assembly detect a defect. The switching assembly works, so that the brush 16 installed on one set of the interference detection assembly is pushed forward and contacts the surface of the insulation layer of the cable 1. The paint pipe 15 is connected to the brush 16, and the interference detection assembly is rotated as a whole to achieve the coating mark of the defective part of the cable 1, which is convenient for subsequent processing. The equipment also has a retraction function. After marking the defective part of the cable 1, the marked part can be retracted to the detection area of the visual inspection mechanism 3, and then the marked position can be accurately detected by the detection camera 8. The coated mark has a light-absorbing effect, and has a higher contrast when re-detected, thereby achieving a more accurate detection function.

[0046] The interference detection assembly includes a second mounting plate 17, a sliding mounting seat 18, a sliding plate 19, a transmission rod 20 and a rotating ring 21. The second mounting plate 17 is fixedly mounted on the rotating disk 14. The axis of the rotating disk 14 is consistent with the axis of the cable 1. The sliding mounting seat 18 is slidably arranged on the second mounting plate 17. The sliding direction of the sliding mounting seat 18 is consistent with the radial length direction of the rotating disk 14. The sliding plate 19 is located on the side of the sliding mounting seat 18 close to the cable 1. The length direction of the transmission rod 20 is consistent with the sliding direction of the sliding mounting seat 18. The rotating ring 21 is slidably arranged at the outer edge of the rotating disk 14, the transmission rod 20 is transmission-connected to the sliding plate 19, the sliding plate 19 is provided with a pressure sensor 22 and a resistance ball seat 23, the resistance ball seat 23 is fixedly mounted on the pressure sensor 22, the transmission rod 20 is sleeved with a first spring 69, the first spring 69 is located on the sliding mounting seat 18, and an inclined resistance plate 24 is fixedly mounted on the sliding plate 19, and the inclination direction of the inclined resistance plate 24 is gradually away from the sliding plate 19 in the direction extending outward from the center of the rotating disk 14.

[0047] When the cable 1 is about to enter the area of the interference detection component, the end of the cable 1 first collides with the inclined interference plate 24. Since the inclined interference plate 24 is fixedly mounted on the sliding plate 19, this interference will push the inclined interference plate 24 and the sliding plate 19 connected thereto, causing them to move along the sliding mounting seat 18 in a direction away from the axis of the cable 1. In this process, the transmission rod 20, which is connected to the sliding plate 19 for transmission, also moves synchronously, thereby compressing the first spring 69 that is sleeved on the transmission rod 20 and located on the sliding mounting seat 18. At the same time, the interference ball seat 23 on the sliding plate 19 also moves outward until it fits tightly with the outer wall of the cable 1. The pressure sensor 22 installed on the sliding plate 19 monitors the pressure at the contact point between the interference ball seat 23 and the insulation layer of the cable 1 in real time, and determines whether there is a defect in the insulation layer by the change in pressure.

[0048] The sliding plate 19 is also fixedly mounted with a first limiting rod 25 (such as Figure 9 As shown), the first limiting rod 25 is slidably connected to the sliding mounting seat 18, and the transmission rod 20 is provided with a threaded section and a telescopic section. The threaded section is located at the end of the transmission rod 20 away from the cable 1, and the telescopic section is arranged at the end of the transmission rod 20 close to the cable 1. A rotatable lock 26 is provided on the telescopic section, one end of the first spring 69 is fixedly connected to the sliding mounting seat 18, and the other end of the first spring 69 is transmission-connected to the rotatable lock 26. A threaded seat 27 is fixedly installed at the end of the sliding mounting seat 18 away from the cable 1, and the threaded seat 27 is threadedly connected to the threaded section of the transmission rod 20, and the position adjustment assembly is transmission-connected to the transmission rod 20.

[0049] The position adjustment assembly primarily adjusts the position of the sliding mount 18 by driving the transmission rod 20 to rotate. When the position adjustment assembly is in operation, the transmission rod 20 begins to rotate, and its threaded section engages with the threaded seat 27. Because the threaded seat 27 is fixedly mounted on the end of the sliding mount 18 away from the cable 1, the rotation of the transmission rod 20 allows the sliding mount 18 to slide relative to the second mounting plate 17, thereby achieving precise adjustment of the position of the sliding mount 18. The rotatable lock 26 ensures effective transmission between the first spring 69 and the transmission rod 20, allowing the first spring 69 to compress and rebound normally when the transmission rod 20 is displaced. Furthermore, the rotatable lock 26 does not hinder the rotation of the transmission rod 20, ensuring that the transmission rod 20 can rotate normally in accordance with the drive of the position adjustment assembly. When the contact pressure between the contact ball seat 23 and the insulation layer of the cable 1 changes, the telescopic section elastically compresses in response to the pressure change. This elastic change maintains close contact between the contact ball seat 23 and the insulation layer of the cable 1. Even if there are slight unevenness or pressure fluctuations on the surface of the insulation layer of cable 1, the telescopic section of the transmission rod 20 can be adjusted in time to ensure that the pressure detected by the pressure sensor 22 always accurately reflects the actual value of the insulation layer of cable 1, thereby improving the stability and reliability of the entire detection process.

[0050] The position adjustment assembly drives the transmission rod 20 through the relative rotation of the rotating ring 21 and the rotating disk 14. The transmission rod 20 is provided with a threaded section and a telescopic section. The threaded section is located at the end away from the cable 1. When the rotating ring 21 and the rotating disk 14 rotate relative to each other, the transmission rod 20 rotates, and its threaded section interacts with a threaded seat 27 fixed to the end of the sliding mount 18 away from the cable 1, driving the sliding mount 18 to slide along the second mounting plate 17. This design allows the position of the sliding mount 18 to be precisely adjusted according to the length of the cable 1, ensuring that the contact ball seat 23 contacts the cable 1 with optimal pressure, greatly improving detection accuracy. This adjustment method also allows for simultaneous and precise adjustment of multiple sliding mounts 18. The first limiting rod 25 is fixedly mounted on the sliding plate 19 and slidably connected to the sliding mount 18, ensuring the stability of the sliding plate 19 during sliding. A rotatable lock 26 is provided on the telescopic section of the transmission rod 20. It ensures effective transmission between the first spring 69 and the transmission rod 20 while not hindering the normal rotation of the transmission rod 20. The telescopic section of the transmission rod 20 can realize the elastic compression function. When the contact pressure between the resistance ball seat 23 and the insulation layer of the cable 1 changes, the telescopic section can automatically adjust to always maintain close contact between the resistance ball seat 23 and the insulation layer of the cable 1, ensuring the continuous accuracy of pressure detection.

[0051] The interference detection mechanism 4 also includes a rotation drive assembly, which includes a first rotation drive 28, a rotating shaft 29, a sliding collar 30 and a transmission gear 31. The first rotation drive 28 is fixedly mounted on the working platform 2, the rotating shaft 29 is horizontally arranged and one end is fixedly connected to the output end of the first rotation drive 28, the length direction of the rotating shaft 29 is consistent with the axial direction of the cable 1, the sliding collar 30 is slidingly arranged on the rotating shaft 29, and the transmission gear 31 is fixedly mounted on the sliding collar 30, and the inner side wall of the sliding collar 30 is provided with a latching tooth 32, and the outer side wall of the rotating shaft 29 is provided with a first horizontal sliding groove 33 that cooperates with the latching tooth 32 along its length direction, a first ring tooth 34 is provided on the outer edge of the rotating disk 14, and a second ring tooth 35 is provided on the outer edge of the rotating ring 21, and the first ring tooth 34 and the second ring tooth 35 are both engaged with the transmission gear 31.

[0052] When the first rotary driver 28 drives the rotating shaft 29 to rotate, the sliding ring 30 rotates along with the rotating shaft 29, thereby driving the transmission gear 31 to rotate. Since the transmission gear 31 is engaged with the first ring gear 34 and the second ring gear 35 at the same time, the rotating disk 14 and the rotating ring 21 will rotate synchronously. In this case, the relative position of the sliding mounting seat 18 and the second mounting plate 17 will not change, and the interference detection component maintains the current detection position and state.

[0053] The position adjustment assembly includes a driven gear 36, a second linear drive 37, a push plate 38, a friction plate 39 and a third spring 40. There are several driven gears 36, and several driven gears 36 correspond one-to-one to several groups of interference detection components. The second linear drive 37 is fixedly mounted on the working platform 2, and the output end of the second linear drive 37 is fixedly connected to the push plate 38, and the push plate 38 is fixedly connected to the sliding collar 30. The third spring 40 is sleeved on the rotating shaft 29, one end of the third spring 40 is fixedly connected to the end of the rotating shaft 29, and the other end of the third spring 40 is fixedly connected to the end of the sliding collar 30. The friction plate 39 is fixedly mounted on the top of the push plate 38 on the side close to the rotating disk 14, and a third ring tooth 41 is fixedly mounted on the outer wall of the rotating ring 21. Several driven gears 36 are meshed with the third ring tooth 41, and the driven gear 36 is fixedly connected to the end of the transmission rod 20 away from the interference ball seat 23.

[0054] When the position of the sliding mount 18 needs to be adjusted, the second linear driver 37 pushes the push plate 38, driving the sliding ring 30 to move along the rotating shaft 29, so that the transmission gear 31 only engages with the second ring gear 35 and disengages from the first ring gear 34. At this time, when the first rotary driver 28 continues to work and drives the rotating shaft 29 to rotate, the rotation of the transmission gear 31 will only drive the rotating ring 21 to rotate relative to the rotating disk 14. The rotation of the rotating ring 21 drives the sliding mount 18 to slide on the second mounting plate 17 through the connection with the transmission rod 20, thereby realizing the adjustment of the position of the sliding mount 18. This design provides a convenient and accurate adjustment method for the interference detection component to adapt to different cable 1 diameters. The operator can quickly and accurately adjust the position of the interference detection component according to actual detection needs, thereby improving the efficiency and flexibility of the detection work.

[0055] The output end of the second linear drive 37 pushes the push plate 38 to switch the position of the transmission gear 31 on the sliding ring 30, from meshing with the first ring teeth 34 of the rotating disk 14 and the second ring teeth 35 of the rotating ring 21 at the same time, to meshing only with the second ring teeth 35 of the rotating ring 21, thereby achieving effective switching of the position of the transmission gear 31. When the second linear drive 37 does not provide driving force, the third spring 40 plays a role, ensuring that the positions of the various components of the device are stable when no position adjustment is performed, and the interference detection component can perform detection work normally. When the transmission gear 31 is disengaged from the first ring teeth 34, the friction plate 39 is in contact with the rotating disk 14, and the friction force is used to prevent the rotating disk 14 from rotating offset when the transmission gear 31 only drives the rotating ring 21 to rotate. This design ensures that the rotating ring 21 can rotate accurately, and avoids affecting the accuracy of the position adjustment of the sliding mounting seat 18 due to the unstable rotation of the rotating disk 14. A third ring tooth 41 is fixedly mounted on the outer wall of the rotating ring 21, and a plurality of driven gears 36 are meshed with the third ring tooth 41, and the driven gears 36 are fixedly connected to the end of the transmission rod 20 away from the interference ball seat 23. When the rotating ring 21 rotates, it drives the plurality of driven gears 36 to rotate synchronously through the third ring tooth 41, and the rotation of the driven gears 36 in turn drives the transmission rod 20 connected thereto to rotate. Since the plurality of transmission rods 20 are respectively connected to a plurality of groups of interference detection components, synchronous position adjustment of the plurality of groups of interference detection components is achieved. This synchronous adjustment method greatly improves the detection efficiency, ensuring that when facing cables 1 with different diameters, a plurality of interference detection components can be adjusted to the appropriate position at the same time, thereby ensuring the coordination and efficiency of the detection work.

[0056] The switching assembly includes a synchronous mounting frame 42, a first linear drive 43, a transmission plate 44, a transmission ring 45, a first articulated seat 46, a second articulated seat 47 and a compression strut 48. The synchronous mounting frame 42 is fixedly connected to the sliding plate 19. The synchronous mounting frame 42 is located at the end of the sliding mounting seat 18 away from the cable 1. The first linear drive 43 is fixedly mounted on the synchronous mounting frame 42. The output end of the first linear drive 43 is fixedly connected to the transmission plate 44. The transmission plate 44 is slidingly set on the paint pipe 15. Two transmission rings 45 are provided on the paint pipe 15. The two transmission rings 45 are both located in the sliding mounting seat 18. The transmission plate 44 is set between the two transmission rings 45. The first articulated seat 46 is fixedly mounted on the end of the paint pipe 15 close to the brush 16. The second articulated seat 47 is fixedly mounted on the end of the transmission rod 20 close to the cable 1. The two ends of the compression strut 48 are respectively hinged to the first articulated seat 46 and the second articulated seat 47. The compression strut 48 is composed of a telescopic rod 49 and a second spring 50.

[0057] In the initial state of the marking mechanism 5, the transmission rod 20 is extended, and the paint pipe 15 is retracted. The compression strut 48, consisting of a telescopic rod 49 and a second spring 50, is hinged at its ends to a first hinged seat 46 fixed to the end of the paint pipe 15 near the brush 16, and a second hinged seat 47 fixed to the end of the transmission rod 20 near the cable 1. At this point, the compression strut 48 is extended, stabilizing the paint pipe 15 and transmission rod 20.

[0058] When a defect in the insulation layer of cable 1 is detected and requires marking, the first linear actuator 43 pushes the transmission plate 44 to slide on the paint pipe 15. The transmission plate 44 slides until it contacts one of the transmission rings 45. Through the transmission plate 44 and transmission ring 45, the paint pipe 15 is pushed toward the cable 1. As the paint pipe 15 moves, the compression strut 48 is squeezed, the telescopic rod 49 contracts, and the second spring 50 is compressed, causing the compression strut 48 to change its tilt. When the paint pipe 15 moves to the appropriate position, the compression strut 48 reopens under the elastic force of the second spring 50. The paint pipe 15 then extends, and the transmission rod 20 retracts. (The compression strut 48 is designed to be compressible to prevent it from getting stuck during switching. It also automatically expands after the switch is complete, eliminating the need for additional power to maintain the state after the switch.) The previously retracted paint brush 16 then adheres to the cable 1, while the previously extended contact ball seat 23 in the corresponding position retracts, completing the switch from detection to marking. This design cleverly utilizes the transmission relationship between the various components to achieve fast and smooth switching between detection and marking functions, and can maintain stability when both functions are implemented.

[0059] A gap is provided between the two transmission rings 45, providing a certain amount of horizontal displacement adjustment space for the transmission rod 20. Due to the presence of the gap, when the transmission rod 20 moves, it will not interfere with the transmission plate 44, thus ensuring the stable operation of the switching assembly, avoiding malfunctions caused by interference between components, and improving the reliability of the marking mechanism 5.

[0060] The paint pipeline 15 is composed of a straight pipe 51, a bellows 52, a first connecting pipe 53, an annular channel 54 and a second connecting pipe 55. The straight pipe 51 is horizontally slidably arranged on the sliding mounting seat 18. The end of the straight pipe 51 close to the cable 1 is connected to the paint brush 16. The other end of the straight pipe 51 is connected to the first connecting pipe 53 through the bellows 52. The first connecting pipe 53 is provided with a solenoid valve, and the switching component is connected to the straight pipe 51 in a transmission manner. The annular channel 54 is fixedly installed at the center of the rotating disk 14. The end of the first connecting pipe 53 away from the straight pipe 51 is connected to the annular channel 54. The second connecting pipe 55 (such as Figure 5 One end of the second connecting pipe 55 is connected to the annular channel 54, and the other end of the second connecting pipe 55 passes through the second support frame 13 and is connected to the external paint source.

[0061] When it is detected that there are defects in the insulation layer of cable 1 that need to be marked, the switching component starts to push the straight tube 51 to slide horizontally on the sliding mounting seat 18. When the switching component is actuated, the straight tube 51 slides in the direction close to the cable 1, so that the paint brush 16 is close to the surface of the insulation layer of the cable 1. At this time, the paint in the external paint source enters the annular channel 54 through the second connecting tube 55, and then enters the straight tube 51 through the first connecting tube 53 and the bellows 52, and is finally applied to the defective part of the cable 1 by the paint brush 16. The design of the annular channel 54 ensures that the paint pipe 15 is in a connected state when rotated to any angle. The bellows 52 has good flexibility and can adapt to the displacement changes of the straight tube 51 during the sliding process, ensuring the smoothness of the paint transmission.

[0062] The transmission mechanism 6 includes a third support frame 56, a clamping transmission roller 57, a sliding block 58 and an adaptive adjustment component. The third support frame 56 is fixedly installed on the working platform 2. Two clamping transmission rollers 57 and two sliding blocks 58 are symmetrically arranged along the vertical center plane. The adaptive adjustment component is transmission-connected to the two sliding blocks 58. The clamping transmission roller 57 is fixedly connected to the sliding block 58. A second horizontal slide groove 59 for the sliding block 58 to slide is horizontally provided on the third support frame 56.

[0063] The third support frame 56 of the transmission mechanism 6 is fixed to the work platform 2. Two sliding blocks 58 slide along the second horizontal slot 59 of the third support frame 56. The adaptive adjustment assembly drives the sliding blocks 58 according to the length of the cable 1, which in turn moves the fixed clamping and transmission rollers 57, adjusting the clamping position. The clamping and transmission rollers 57 have a small center diameter and gradually increase in diameter at both ends. This adapts to cables 1 of varying lengths, stably clamping and transmitting the cable 1, ensuring smooth movement during testing and providing a good foundation for subsequent testing steps.

[0064] The adaptive adjustment component includes a lifting cylinder 60, a lifting plate 61, a first hinge link 62, a second hinge link 63, a horizontal extension plate 64, a sliding seat 65, a second rotary driver 66, a rotating wheel 67 and a synchronous transmission belt 68. The lifting cylinder 60 is fixedly installed on the working platform 2, and the lifting plate 61 is vertically slidable. The output end of the lifting cylinder 60 is fixedly connected to the lifting plate 61. There are two first hinge links 62 and they correspond to the two sliding blocks 58 one by one. One end of the first hinge link 62 is hinged to the lifting plate 61, and the other end of the first hinge link 62 is hinged to the sliding block 58. The horizontal extension plate 64 is fixedly installed on the third support frame 56. The length direction of the horizontal extension plate 64 is consistent with the axial direction of the cable 1. The horizontal extension plate 64 is provided with a third horizontal slide groove consistent with its length direction. The sliding seat 65 is slidably set in the third horizontal slide groove. One end of the second hinged link 63 is hinged to the lifting plate 61, and the other end of the second hinged link 63 is hinged to the sliding seat 65. The sliding seat 65 is provided with two wheels 67 connected by meshing gears. The second rotation driver 66 is fixedly installed on the sliding seat 65. The output end of the second rotation driver 66 is connected to one of the wheels 67. The two wheels 67 are respectively connected to the two clamping transmission rollers 57 through two synchronous transmission belts 68.

[0065] When the clamping and transmission state of the transmission mechanism 6 needs to be adjusted based on the length of the cable 1, the adaptive adjustment assembly begins operation. First, the lifting cylinder 60, fixed to the work platform 2, is activated, and its output end pushes the lifting plate 61 to slide vertically upward. The lifting plate 61 is hinged to the two sliding blocks 58 via a first hinged link 62. As the lifting plate 61 rises, the first hinged link 62 drives the two sliding blocks 58 to slide within the second horizontal slot 59 of the third support frame 56, thereby adjusting the distance between the two clamping and transmission rollers 57 to accommodate cables 1 of varying lengths. Simultaneously, the lifting plate 61 is hinged to the sliding seat 65 via a second hinged link 63. As the lifting plate 61 rises, the second hinged link 63 drives the sliding seat 65 to slide within the third horizontal slot. When the second rotary actuator 66 is activated, it drives the connected runner 67 to rotate. Through the transmission of the meshing gears, the other runner 67 also rotates synchronously in the opposite direction. The two rotating wheels 67 are respectively connected to the two clamping transmission rollers 57 through two synchronous transmission belts 68. The rotation of the rotating wheel 67 drives the clamping transmission roller 57 to rotate through the synchronous transmission belt 68, thereby realizing stable transmission of the cable 1. The synchronous transmission belt 68 can ensure that a stable rotational driving force is provided when clamping cables 1 with different diameters.

[0066] The various components of the adaptive adjustment assembly work together to precisely adjust the gripping and transmission state of the transmission mechanism 6 according to the length of the cable 1. Through the coordinated interaction of components such as the lifting cylinder 60, lifting plate 61, first articulated link 62, second articulated link 63, sliding seat 65, second rotary driver 66, rotating wheel 67, and synchronous transmission belt 68, the mechanism efficiently adapts to varying cable 1 lengths, enhancing the stability and reliability of the transmission process and ensuring that the cable 1 can smoothly and steadily pass through the transmission mechanism 6 and enter the subsequent inspection process.

[0067] A method for detecting a cable insulation layer comprises the following steps:

[0068] S1: Place the cable 1 on the work platform 2 and start the transmission mechanism 6. The transmission mechanism 6 adjusts the spacing and position of the clamping transmission rollers 57 according to the length of the cable 1 through the adaptive adjustment component, stably clamps the cable 1, and smoothly sends it into the internal detection area of the equipment;

[0069] S2: When the cable 1 enters the area of the visual inspection mechanism 3, the visual inspection mechanism 3 is turned on. The operator adjusts the position of the inspection camera 8 according to the actual situation of the cable 1, and the ring light source 9 lights up. The three inspection cameras 8 are arranged in a ring at an angle of 120 degrees around the axis of the cable 1 insulation layer. They quickly and accurately capture images of the cable 1 insulation layer from multiple angles and detect surface defects such as ruptures, overlaps, protrusions, depressions, pinholes, cracks, and wrinkles.

[0070] S3: Cable 1 continues to travel to the area of the interference detection mechanism 4, which is activated. The position adjustment assembly drives the rotating ring 21 according to the length of the cable 1, synchronously adjusting the positions of the multiple sliding mounts 18 so that the interference detection assembly contacts the insulation layer of the cable 1 with appropriate pressure. The interference detection assembly rotates with the rotating disk 14, and the pressure sensor 22 monitors the pressure changes at the contact area, accurately determining the location of the insulation defect, completing the secondary inspection, and verifying the visual inspection results.

[0071] S4: If the visual inspection mechanism 3 and the interference detection component detect that there is a defect in the insulation layer of the cable 1, the marking mechanism 5 starts to work, the switching component pushes the coating brush 16 to contact the surface of the insulation layer of the cable 1, the paint pipe 15 is connected to the coating brush 16, and the interference detection component is rotated as a whole to apply a coating mark to the defective part of the cable 1. Subsequently, the equipment retraction function is activated to retract the marked part to the detection area of the visual inspection mechanism 3. The detection camera 8 again accurately detects the coating mark position, using the light absorption effect of the mark to improve the contrast and further confirm the defect;

[0072] S5: After the detection is completed, the transmission mechanism 6 sends the detected cable 1 out of the device, ending the detection process.

[0073] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
