Description

Technical Field

[0001] This utility model relates to the field of holographic detection technology for cable defects, and in particular to a multi-angle scanning holographic detection instrument for cable defects. Background Technology

[0002] The cable defect holographic inspection instrument is an advanced non-destructive testing device specifically designed to identify and locate internal structural defects in cables. Utilizing holographic imaging technology, this instrument generates three-dimensional images of the cable's internal structure, clearly displaying the condition of the insulation, conductor, and shielding layers, helping technicians quickly identify potential problems.

[0003] Cables may have complex layouts or be installed in confined spaces. Fixed-angle inspection instruments may not be able to scan the cable comprehensively from all directions, resulting in some areas remaining undetected. For cables with bends, branches, or other complex geometries, single-angle inspection equipment may not be able to adapt to these variations, thus missing potential problems. Because the angle cannot be adjusted, the inspection instrument may have blind spots, especially at critical locations such as cable joints and terminations, easily missing small but important defects. Cables with different materials and surface properties exhibit different reflection characteristics at different incident angles. A fixed angle may lead to poor signal reflection, affecting image quality and the accuracy of defect identification.

[0004] Therefore, it is necessary to design a multi-angle scanning holographic cable defect detector to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of fixed-angle detectors, such as blind spots, difficulty in adapting to changes such as bending and branching, and easy omission of minor defects in critical parts when the cable structure is complex or space is limited, and the fixed incident angle affects the reflection effect and imaging accuracy, this utility model provides a multi-angle scanning holographic cable defect detector.

[0006] Technical Solution: A multi-angle scanning holographic cable defect detector includes a mounting base, a rotating shaft, a fixed block, a turntable, a detector, probes, a control panel, sensors, a vertical angle adjustment component, and a horizontal angle adjustment component. The mounting base is rotatably connected to the rotating shaft, and a fixed block is fixedly connected to the rotating shaft. A turntable is rotatably connected to the top of the fixed block. The detector is fixedly connected to the left side of the turntable, and probes are fixedly connected to both sides of the left side of the turntable. A control panel is fixedly connected to the top of the turntable. The detector and the two probes are electrically connected to the control panel. Sensors are fixedly connected to both sides of the top of the turntable, and both sensors are electrically connected to the control panel. A vertical adjustment component is provided between the fixed block and the mounting base, and a horizontal adjustment component is provided between the turntable and the fixed block.

[0007] In a preferred embodiment of this invention, the detector is located between two probes.

[0008] In a preferred embodiment of the present invention, a detection platform is also included, and the detection platform is fixedly connected to the left side of the mounting base.

[0009] In a preferred embodiment of the present invention, the vertical angle adjustment component includes a first motor, a screw rod, a rack, and a toothed block. The first motor is fixedly connected to the right side of the mounting base, and the screw rod is fixedly connected to the output shaft of the first motor. The rack is slidably connected to the left side of the mounting base. The rack has a threaded groove on the right side that matches the screw rod. The toothed block is fixedly connected to the lower part of the fixing block, and the toothed block meshes with the rack.

[0010] In a preferred embodiment of the present invention, the horizontal angle adjustment component includes a second motor, a gear and a gear ring. The second motor is fixedly connected to the front of the fixing block, and the gear is fixedly connected to the output shaft of the second motor through the fixing block. The gear ring is fixedly sleeved on the bottom of the turntable and meshes with the gear.

[0011] In a preferred embodiment of this utility model, it further includes a supplementary light, a placement seat, a battery, and a cover plate. Supplementary lights are fixedly connected to both sides of the left side of the turntable. Both supplementary lights are electrically connected to the control panel. Two sets of placement seats are fixedly connected to the right side of each supplementary light. There are multiple placement seats in both sets. Each placement seat contains a battery. A cover plate is slidably placed on the upper part of each set of placement seats.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses a first motor to drive the screw rod to rotate, which in turn drives the rack to move, thereby causing the detector's fixed block to rotate synchronously, thus achieving precise adjustment of the vertical angle of the cable detector and ensuring that the cable is fully scanned from all angles, avoiding the problem of missing potential defects due to limited viewing angle. The second motor drives the gear to mesh with the gear ring, which drives the turntable to rotate, further realizing the horizontal angle adjustment and ensuring that the detector can work at any required angle.

[0013] 2. By combining the function of a supplementary light, this utility model can effectively illuminate the working area and improve image clarity, thereby enhancing the accuracy and reliability of detection. The supplementary light is powered by a battery. When the battery is depleted, simply pull the cover forward to remove the old battery and replace it with a new one, then push the cover back to continue using it, greatly simplifying the maintenance process.

[0022] Example: A multi-angle scanning holographic cable defect detector, such as... Figures 1-6 As shown, the device includes a mounting base 1, a detection platform 2, a rotating shaft 3, a fixing block 4, a turntable 5, a detector 6, a probe 7, a control panel 8, a sensor 9, a vertical angle adjustment assembly, and a horizontal angle adjustment assembly. The detection platform 2 is mounted on the upper left side of the mounting base 1 by screws. The rotating shaft 3 is rotatably connected to the upper part of the mounting base 1. The fixing block 4 is welded to the rotating shaft 3. The turntable 5 is rotatably connected to the top of the fixing block 4. The detector 6 is mounted on the middle left side of the turntable 5 by screws. Probes 7 are mounted on the front and rear sides of the left side of the turntable 5 by screws. The detector 6 is located between the two probes 7. The control panel 8 is mounted on the center top of the turntable 5 by screws. The detector 6 and the two probes 7 are electrically connected to the control panel 8. Sensors 9 are mounted on the front and rear sides of the top of the turntable 5 by screws. The two sensors 9 are electrically connected to the control panel 8. A vertical adjustment assembly is provided between the fixing block 4 and the mounting base 1, and a horizontal adjustment assembly is provided between the turntable 5 and the fixing block 4.

[0023] like Figure 1 and Figure 4As shown, the vertical angle adjustment assembly includes a first motor 10, a screw rod 11, a rack 12, and a toothed block 14. The first motor 10 is mounted on the right side of the mounting base 1 by screws. The output axis of the first motor 10 extends to the left and is welded to the screw rod 11. The rack 12 is slidably connected to the left side of the mounting base 1. The rack 12 has a threaded groove 13 on the right side inside, which is adapted to the screw rod 11. The toothed block 14 is welded to the lower part of the fixing block 4 and meshes with the rack 12.

[0024] like Figure 6 As shown, the horizontal angle adjustment assembly includes a second motor 15, a gear 16 and a gear ring 17. The second motor 15 is installed on the front of the fixing block 4 by screws. The output axis of the second motor 15 extends upward through the fixing block 4 and is welded with the gear 16. The gear ring 17 is fixedly sleeved on the bottom of the turntable 5 and meshes with the gear 16.

[0025] like Figure 1 , Figure 6 and Figure 7 As shown, it also includes supplementary lights 18, mounting bases 19, batteries 20, and cover plates 21. Supplementary lights 18 are installed on both the front and rear sides of the left side of the turntable 5 by screws. Both supplementary lights 18 are electrically connected to the control panel 8. Two sets of mounting bases 19 are installed on the right side of the two supplementary lights 18 by screws. There are two sets of mounting bases 19. Each mounting base 19 contains a battery 20. A cover plate 21 is slidably placed on the top of each set of mounting bases 19.

[0026] When this device is needed, first place the cable to be tested on the testing platform 2. Then, start the first motor 10 via the control panel 8. The output shaft of the first motor 10 drives the screw rod 11 to rotate clockwise or counterclockwise, driving the rack 12 to move left or right, thereby causing the fixed block 4 of the detector 6 to rotate synchronously. When the detector 6 is adjusted to a suitable vertical angle, turn off the first motor 10 to stop operation. Next, start the second motor 15 via the control panel 8. Its output shaft drives the gear 16 to rotate clockwise or counterclockwise. Since the gear 16 meshes with the gear ring 17, the turntable 5 rotates clockwise or counterclockwise accordingly. When the detector 6 is horizontally adjusted to a suitable angle, turn off the second motor 15 to stop operation. To ensure good testing results, before starting the testing instrument 6, the supplementary light 18 can be turned on via the control panel 8 to illuminate the working area. The supplementary light 18 is powered by the battery 20. If the battery 20 is depleted, the cover 21 can be pulled forward to remove it, a new battery 20 can be replaced, and then the cover 21 can be pushed back. Once everything is ready, the testing instrument 6 can be started via the control panel 8, and the probe 7 will begin scanning the cable surface for defect detection. During the detection process, the sensor 9 transmits data to the control panel 8, and the operator can view the detection status in real time via the control panel 8. After the detection is completed, the testing instrument 6 and probe 7 can be turned off via the control panel 8. If the cable needs to be tested again, the above operation can be repeated.
