DETAILED DESCRIPTION

[0036] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0037] The primary material used on cable surfaces is polyvinyl chloride (PVC), which offers excellent insulation properties. The performance parameters of the cable surface directly determine the safety and stability of the cable. Therefore, fault detection of the cable surface is essential during the production process.

[0038] Traditional cable surface fault detection devices only detect convex and concave defects on the cable surface through optical detection methods such as ultrasound or laser to ensure the quality of the cable surface.

[0039] However, the detection methods of traditional cable surface fault detection devices are relatively limited.

[0040] The present application provides a cable surface fault detection device, which detects the anti-extrusion ability of the cable surface by arranging an extrusion detection unit on a box body, and arranges optical detection units on both sides of the extrusion detection unit to detect surface defects of the cable surface before and after the extrusion detection, and guides the cable to the extrusion detection unit and the optical detection unit through a guide component; the optical detection and extrusion test of the cable are realized, and the extrusion test simulates the extrusion of the cable during subsequent winding, storage or use. The optical detection is performed before and after the extrusion test of the cable, and a real-time comparison before and after the extrusion can be realized to detect possible damage to the cable surface during extrusion, thereby reducing the limitations of cable surface detection.

[0041] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0042] The present application embodiment provides a cable surface fault detection device, referring to Figure 1 , the cable surface fault detection device includes:

[0043] Box 100;

[0044] The extrusion detection unit 200 is connected to the box 100 and is used to squeeze the cable 1 to detect the anti-extrusion ability of the cable 1 surface;

[0045] Two sets of optical inspection units 300, the optical inspection units 300 are connected to the box 100, and the optical inspection units 300 are respectively located on both sides of the extrusion inspection unit 200 to respectively detect surface defects of the cable 1 before and after extrusion;

[0046] A plurality of guide assemblies 400 are provided on the box body 100 , and the guide assemblies 400 are used to guide the cable 1 into the squeeze detection unit 200 and the optical detection unit 300 respectively.

[0047] Exemplarily, the box body 100 is a rectangular structure, the squeeze detection unit 200 is arranged on the top of the box body 100 , and the two groups of optical detection units 300 are respectively arranged on both sides of the box body 100 .

[0048] Performing optical inspections before and after the compression test on the cable 1 allows for real-time comparison of surface changes before and after the compression, further improving the inspection effect. Furthermore, placing the optical inspection units 300 on both sides of the housing 100 reduces the length of the housing 100, thereby reducing the volume and footprint of the entire inspection device.

[0049] In other embodiments, the squeeze detection unit 200 and the optical detection unit 300 may be disposed on the same side of the box 100 , and the squeeze detection unit 200 may be located between the two optical detection units 300 .

[0050] Arranging both the extrusion detection unit 200 and the optical detection unit 300 on the top of the box 100 is conducive to facilitating the transportation detection of the cable 1, reducing the turning of the cable 1, and thus reducing the number of guide components 400.

[0051] The cable 1 is tested for its anti-extrusion ability by the extrusion detection unit 200, and the surface state of the cable 1 before and after extrusion is detected by the optical detection unit 300, so that the changes of the cable 1 under stress can be compared in real time. This comparative detection method can effectively identify small deformations, cracks or other surface defects caused by extrusion, thereby improving the accuracy and reliability of detection. The two groups of optical detection units 300 are respectively located on both sides of the extrusion detection unit 200, and can scan the surface of the cable 1 from different angles to avoid missed detection due to a single viewing angle. The device can compare the surface state of the cable 1 before and after extrusion in real time, and quickly identify the location and type of defects. This real-time detection capability can significantly shorten the detection time and improve the detection efficiency. In addition, the extrusion test simulates the extrusion of the cable 1 during the subsequent winding, storage or use of the cable. Optical detection is performed on the cable 1 before and after the extrusion test, so that real-time comparison before and after extrusion can be achieved to detect possible damage to the surface of the cable 1 during extrusion, thereby reducing the limitations of the surface detection of the cable 1.

[0052] In one possible implementation, refer to Figure 1 and Figure 2 The cable surface fault detection device also includes an adjustment component 500. An adjustment groove 110 is provided on the box 100. The adjustment component 500 is located in the adjustment groove 110. The optical detection unit 300 is connected to the adjustment component 500. The adjustment component 500 is used to adjust the distance between the optical detection unit 300 and the box 100 so that the cable 1 and the optical detection unit 300 are coaxial.

[0053] The housing 100 features symmetrical adjustment slots 110 on either side. The slots 110 are tilted, and the adjustment assembly 500 is mounted within them. The optical inspection unit 300 is connected to the adjustment assembly 500, allowing the adjustment assembly 500 to move the optical inspection unit 300 within the tilted slots. This allows the adjustment assembly 500 to adjust the distance between the optical inspection unit 300 and the housing 100, ensuring that the cable 1 and the optical inspection unit 300 are coaxial, facilitating optical inspection of the cable 1 surface. The adjustment assembly 500 aligns the optical inspection unit 300 and the cable 1 to a coaxial position, ensuring a more uniform and comprehensive scan of the cable 1 surface. This coaxial arrangement reduces detection errors caused by angular deviation, thereby improving the accuracy of detecting surface faults (such as cracks and wear) on the cable 1. The adjustment assembly 500 allows for flexible adjustment based on the diameter and position of the cable 1, enabling the optical inspection unit 300 to quickly adapt to cables of varying specifications and conditions. This flexibility reduces pre-inspection preparation time and debugging efforts, thereby improving overall inspection efficiency. At the same time, when the optical detection unit 300 is coaxial with the cable 1, signal interference or misjudgment caused by position offset can be avoided, thereby improving the reliability of detection.

[0054] In one possible implementation, refer to Figure 1 and Figure 2 The adjustment assembly 500 includes a first screw 510, an adjustment block 520 and a mounting frame 530. The first screw 510 is rotatably set in the adjustment groove 110, and one end of the first screw 510 is inclined toward the middle of the box body 100; the adjustment block 520 is slidably set on the adjustment groove 110, and the adjustment block 520 is threadedly sleeved on the first screw 510, the mounting frame 530 is set on the adjustment block 520, and the optical detection unit 300 is set on the mounting frame 530.

[0055] Furthermore, the first lead screw 510 is adapted to the adjustment slot 110 so that the bottom of the first lead screw 510 is tilted toward the middle of the housing 100. The first lead screw 510 is an electrically controlled lead screw, which is driven and controlled by a motor to drive the first lead screw 510 to rotate. The adjustment block 520 is threadedly mounted on the first lead screw 510, and the side wall of the adjustment block 520 abuts against the side wall of the adjustment side to limit the rotation of the adjustment block 520. The mounting frame 530 is fixed to the adjustment block 520 by bolts. The adjustment block 520 slides in the vertical direction. When the first lead screw 510 rotates, it drives the adjustment block 520 to move along the axis of the first lead screw 510, thereby driving the mounting frame 530 to move, thereby changing the distance between the mounting frame 530 and the center of the housing 100, and thereby changing the position of the optical detection unit 300 mounted on the mounting frame 530, thereby adjusting the position according to cables 1 of different diameters and improving the adaptability of the device.

[0056] Furthermore, the optical inspection unit 300 includes an electrically controlled adjustment ring 310 and an optical recognition module 320. The electrically controlled adjustment ring 310 is mounted on the mounting frame 530 to maintain coaxiality with the cable 1, which is threaded through the electrically controlled adjustment ring 310. The optical recognition module 320 is mounted on the electrically controlled adjustment ring 310 to detect defects on the surface of the cable 1 and record the spacing and surface unevenness of the cable 1. The electrically controlled adjustment ring 310 drives the optical recognition module 320 to rotate around the cable 1. The rotation of the electrically controlled adjustment ring 310 ensures that the optical recognition module 320 can optically scan and record parameters of the cable 1 surface. The optical recognition module 320 then compares the optical scan parameters of the cable 1 surface at the same location with those of another optical inspection unit 300 based on the conveying speed of the cable 1. This allows for comparative testing and calculation of the rate at which surface faults occur on the cable 1.

[0057] In one possible implementation, refer to Figure 1 and Figure 3 The guide assembly 400 includes a connecting frame 410, a driving wheel 420, a limiting wheel 430 and a swinging member 440. One end of the connecting frame 410 is hinged on the box body 100. The driving wheel 420 and the limiting wheel 430 are both rotatably set on the connecting frame 410 and are respectively used to contact the two sides of the cable 1. The driving wheel 420 is used to drive the cable 1 to move. The swinging member 440 is set on the box body 100 and connected to the connecting frame 410. The swinging member 440 is used to drive the connecting frame 410 to swing to adjust the position of the cable 1.

[0058] The guide assembly 400 further includes a mounting block, which is fixed to the housing 100 by bolts or welding. One end of the connecting frame 410 is hingedly connected to the mounting block. The driving wheel 420 and the limiting wheel 430 are both rotatably connected to the connecting frame 410, and there is a gap between the driving wheel 420 and the limiting wheel 430 so that the cable 1 can pass between the driving wheel 420 and the limiting wheel 430. The driving wheel 420 has a motor drive structure, which causes the driving wheel 420 to actively rotate, thereby driving the cable 1 to rotate. The cable 1 contacts the driving wheel 420 and the limiting wheel 430 respectively to limit the position of the cable 1. The swing member 440 drives the connecting frame 410 to deflect, thereby driving the driving wheel 420 and the limiting wheel 430 to change position, thereby achieving adjustment of the position of the cable 1. By cooperating with two adjacent limiting assemblies, the position of the cable 1 on the same side of the housing 100 can be adjusted, so that cables 1 of different diameters can be coaxial with the optical detection unit 300. After use, the guide assembly 400 can be attached to the box body 100 by rotating the connecting frame 410, thereby reducing the volume of the device and facilitating the storage of the device.

[0059] The swing member 440 is an electrically controlled telescopic rod, one end of which is hinged to the box 100, and the other end is hinged to the connecting frame 410. In other embodiments, the swing member 440 can also be a hydraulic cylinder, a pneumatic cylinder, etc., which will not be described in detail here.

[0060] Exemplarily, four sets of guide assemblies 400 are provided, with two sets of guide assemblies 400 symmetrically arranged on either side of the box 100 to guide the input and output cables 1; the other two sets of guide assemblies 400 are installed at the corners of the top of the box 100 to achieve corner guidance of the cables 1. Of course, in other embodiments, different numbers of guide assemblies 400 can be provided and installed in desired locations according to actual needs, which will not be described in detail here.

[0061] The guide assembly 400 contacts both sides of the cable 1 through the drive wheel 420 and the limiting wheel 430, and can accurately guide the cable 1 through the detection area. The drive wheel 420 is responsible for driving the cable 1 to move, ensuring that the cable 1 maintains a stable operating speed during the detection process; the limiting wheel 430 limits the lateral displacement of the cable 1 to prevent the cable 1 from deviating from the detection path during operation. It ensures that the cable 1 always maintains an accurate position and a stable operating state during the detection process, avoiding detection errors caused by the offset or jitter of the cable 1, thereby significantly improving the accuracy and reliability of the detection. This makes it possible to dynamically adjust the position of the cable 1, so that the guide assembly 400 can flexibly adjust the position of the cable 1 according to the diameter and shape of the cable 1 and the specific needs during the detection process. By replacing sliding friction with rolling friction, the wear between the surface of the cable 1 and the guide assembly 400 can be significantly reduced, extending the service life of the cable 1.

[0062] In one possible implementation, refer to Figure 1 and Figure 3 The extrusion detection unit 200 includes an assembly frame 210, an adjustment frame 220, a rotating member 230 and two extrusion wheels 240. The assembly frame 210 is connected to the box body 100, the adjustment frame 220 is set on the assembly frame 210, and the extrusion wheels 240 are rotatably set on the adjustment frame 220 to clamp the cable 1 between the two extrusion wheels 240. The rotating member 230 is set on the assembly frame 210, and the rotating member 230 is used to drive the extrusion wheels 240 to rotate around the cable 1.

[0063] Among them, the two extrusion wheels 240 are rotatably mounted on the adjustment frame 220, and there is a spacing between the two extrusion wheels 240 for the cable 1 to pass through. When the cable 1 is passed between the two extrusion wheels 240, the two extrusion wheels 240 are in contact with the outer side wall of the cable 1, thereby achieving extrusion of the outer surface of the cable 1. One of the extrusion wheels 240 has a motor drive structure to improve the conveying effect of the cable 1. In order to adapt to different cable 1 diameters, the position of one of the extrusion wheels 240 can be adjusted to change the spacing between the two extrusion wheels 240. The position of the extrusion wheel 240 can be adjusted by using an electric telescopic rod, a motor screw structure, etc., which will not be described in detail here.

[0064] Reference Figure 3 and Figure 4 In order to achieve a comprehensive circumferential extrusion test on the cable 1, a rotating shaft 250 is rotatably connected to the assembly frame 210. The rotating shaft 250 is a tubular structure. The rotating shaft 250 passes through the assembly frame 210. The cable 1 passes through the rotating shaft 250 and contacts the extrusion wheel 240. The adjustment frame 220 is fixed on the rotating shaft 250. The adjustment frame 220 rotates around the rotating shaft 250 and is connected to the assembly frame 210. The two extrusion wheels 240 are symmetrically arranged on both sides of the rotating shaft 250. The rotating member 230 is used to drive the adjusting frame 220 to rotate around the rotating shaft 250, so that the two extrusion wheels 240 rotate around the cable 1.

[0065] The extrusion detection unit 200 clamps the cable 1 in the middle through two extrusion wheels 240, and drives the extrusion wheels 240 to rotate around the cable 1 through the rotating member 230. This design can simulate the extrusion stress that the cable 1 may be subjected to during actual use, such as the external force that the cable 1 may encounter during laying, installation or operation. By controlling the pressure and rotation speed of the extrusion wheel 240, the extrusion resistance of the cable 1 can be quantitatively evaluated. This simulation test can help to discover potential problems of the cable 1 under stress in advance, such as deformation and damage of the insulation layer, thereby ensuring the safety and reliability of the cable 1. By simulating the stress state through the extrusion detection unit 200 and combining the image comparison function of the optical detection unit 300, the detection device can comprehensively evaluate the surface changes of the cable 1 during the stress process. This collaborative detection method not only improves the detection accuracy, but also provides richer detection data, providing strong support for the quality assessment and maintenance of the cable 1.

[0066] In one possible embodiment, the rotating member 230 includes a telescopic rod, one end of which is hinged to the assembly frame 210, and the other end is hinged to the adjustment frame 220. The adjustment frame 220 is rotatably connected to the assembly frame 210, and the rotation axis of the adjustment frame 220 coincides with the axis of the cable 1, so that the extrusion wheel 240 on the adjustment frame 220 rotates around the cable 1.

[0067] The telescopic direction of the telescopic rod is perpendicular to the rotation axis of the adjustment frame 220, so that the adjustment frame 220 can be driven to rotate by contracting the telescopic rod. The swing angle of the telescopic rod can reach 90° during the telescopic process, so that the telescopic rod has a reciprocating adjustment range of 180°, so that the two extrusion wheels 240 rotate together around the cable 1 for one circle, thereby achieving comprehensive circumferential extrusion of the cable 1.

[0068] The telescopic rod is an electric telescopic rod, so as to facilitate the control of the rotating member 230. In other embodiments, a hydraulic rod, a cylinder or the like can be used instead of the telescopic rod, which will not be described in detail herein.

[0069] In other embodiments, the rotating member 230 may also be a motor gear structure, which is connected to the rotating shaft 250 through the motor gear structure to achieve the rotation of the adjustment frame 220 and the extrusion wheel 240 thereof.

[0070] Furthermore, two squeeze detection units 200 are provided, and both squeeze detection units 200 are located at the top of the box body 100 and symmetrically arranged along the middle of the box body 100. The provision of two squeeze detection units 200 is conducive to improving the reliability of detection and reducing detection errors.

[0071] In one possible implementation, refer to Figure 1 and Figure 2 The cable surface fault detection device also includes an environmental simulation test unit 600 and a lifting assembly 700. The environmental simulation test unit 600 is used to simulate the environment in which the cable 1 is located. The environmental simulation test unit 600 is arranged in the box 100, the lifting assembly 700 is arranged on the box 100, and the extrusion detection unit 200 is arranged on the lifting assembly 700. The lifting assembly 700 is used to move the extrusion detection unit 200 together with the cable 1 into the environmental simulation test unit 600.

[0072] Lifting assembly 700 is used to move the extrusion detection unit 200, along with the cable 1, into the environmental simulation test unit 600, allowing the cable 1 to undergo extrusion testing under different environmental conditions. This dynamic testing method monitors the surface changes of the cable 1 in real time under the dual effects of force and environmental changes, helping to identify potential environmental defects and improving the comprehensiveness of the test. The automated design of lifting assembly 700 allows the cable 1 to be quickly switched between different testing units, eliminating the need for frequent manual adjustments. This not only improves testing efficiency but also reduces errors introduced by manual operation.

[0073] In one possible implementation, refer to Figure 1 and Figure 2The lifting assembly 700 includes a lifting frame 710 and a driving member 720. The lifting frame 710 is slidably inserted into the top of the box 100. The extrusion detection unit 200 is set on the lifting frame 710. The driving member 720 is set in the box 100 and connected to the lifting frame 710. The driving member 720 is used to drive the lifting frame 710 to move in or out of the environmental simulation test unit 600.

[0074] Exemplarily, the drive member 720 includes a second lead screw 721 and a sliding block 722. The second lead screw 721 is rotatably connected to the housing 100 and is an electrically controlled lead screw, i.e., it includes a motor drive and control structure. The sliding block 722 is threadedly threaded onto the second lead screw 721 and abuts against the sidewall of the housing 100, thereby limiting its rotation with the housing 100. The lift 710 is fixedly connected to the sliding block 722. The rotation of the second lead screw 721 causes the sliding block 722 to slide up and down within the housing 100, thereby driving the lift 710 to move into or out of the environmental simulation test unit 600.

[0075] Furthermore, two driving members 720 are provided, and the lifting frame 710 is a U-shaped structure. The two ends of the lifting frame 710 are respectively connected to the two driving members 720 to synchronously drive the lifting frame 710 to move, thereby improving the stability of the movement of the lifting frame 710.

[0076] In one possible embodiment, the environmental simulation test unit 600 includes an environmental simulation test chamber 610, a feed pipe 620 and a discharge pipe 630. The environmental simulation test chamber 610 is arranged in the box body 100, and one of the feed pipe 620 and the discharge pipe 630 is arranged at the bottom of the environmental simulation test chamber 610, and the other is arranged on the side wall of the environmental simulation test chamber 610.

[0077] The environmental simulation test chamber 610 is located inside the box 100 , and the tops of the box 100 and the environmental simulation test chamber 610 are both opened to facilitate the lifting assembly 700 to move the cable 1 into the environmental simulation test chamber 610 .

[0078] One of the feed pipe 620 and the discharge pipe 630 is located at the bottom of the environmental simulation test chamber 610, while the other is located on the sidewall of the chamber. The functions of the feed pipe 620 and the discharge pipe 630 are interchangeable. When conveying cold air, water, or corrosive liquid, the feed pipe 620 is the pipe on the sidewall of the chamber 610, while the pipe at the bottom of the chamber 610 serves as the discharge pipe 630. When conveying hot air, the feed pipe 620 is the pipe at the bottom of the chamber 610, while the pipe on the sidewall serves as the discharge pipe 630. Material is continuously fed into the feed pipe 620 to simulate the environment in which the cable 1 is exposed, and then discharged from the discharge pipe 630.

[0079] In some embodiments, the environmental simulation test chamber 610 is integrated with the housing 100 .

[0080] The cable surface fault detection device provided in the embodiment of the present application detects the anti-extrusion ability of the surface of the cable 1 by arranging an extrusion detection unit 200 on the box body 100, and arranges optical detection units 300 on both sides of the extrusion detection unit 200 to detect surface defects of the cable 1 before and after the extrusion detection, and guides the cable 1 into the extrusion detection unit 200 and the optical detection unit 300 through the guide component 400; optical detection and extrusion testing of the cable 1 are realized, and the extrusion test simulates the extrusion of the cable during the subsequent winding, storage or use of the cable. Optical detection is performed before and after the extrusion test of the cable 1, and real-time comparison before and after the extrusion can be realized to detect possible damage to the cable surface during extrusion, thereby reducing the limitations of cable surface detection.
