Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and specifically to a cable condition testing device. Background Technology

[0002] With the increasing demands for cable reliability in the power and communication sectors, it has become a necessity to equip cables with professional cable condition testing equipment at the factory to ensure product quality. Therefore, cable condition testing equipment is set up to collect signals through external ultrasonic sensors. After signal processing and analysis, the signals can identify potential problems such as partial discharge and insulation delamination, thereby realizing cable condition testing.

[0003] Chinese Patent Publication No. CN220399311 U discloses a cable testing device, aiming to solve the problems of existing cable testing methods, such as damage to the cable body and shortened cable life caused by testing cables through withstand voltage tests, and the inability to effectively detect cable defects due to the lack of intuitive visualization of the cable's internal condition. The cable testing device provided by this utility model includes a testing mechanism and a conveying mechanism; the testing mechanism includes a first annular portion, a second annular portion, a driving portion, and an X-ray module; the second annular portion is slidably connected to the first annular portion; the driving portion is provided with a toothed ring, which can drive the second annular portion to rotate around its own axis, so that the X-ray module moves circumferentially along the first annular portion; the conveying mechanism includes a frame plate, a pulley portion, and a conveying cylinder; a cable is arranged between the conveying cylinder and the pulley portion; the conveying cylinder can convey the cable to the inner side of the second annular portion.

[0004] The existing device still has the following shortcomings: Because the existing device lacks a flexible adjustment structure to adapt to different cable diameters, it is not convenient to fine-tune the position of the ultrasonic flaw detector according to the cable diameter. As a result, when facing cables with large diameter differences, the flaw detector is difficult to maintain the best detection posture and coupling effect at all times. This not only affects the accuracy and integrity of the detection data, but also requires manual time to repeatedly adjust, reducing the overall detection efficiency. Utility Model Content

[0005] This invention provides a cable condition inspection device that solves the problem of the aforementioned background technology lacking adaptability to different cable diameters. This results in the flaw detector being unable to maintain the optimal inspection posture and coupling effect when facing cables with large diameter differences, which not only affects the accuracy and completeness of the inspection data but also reduces the overall inspection efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a cable condition detection device, including a workbench, and further comprising:

[0008] A base plate is fixed to the bottom of the workbench, and a control box is fixed to one side of the top of the base plate;

[0009] A support frame is fixed on both sides of the top of the workbench, and a support roller is rotatably connected inside the support frame. A display screen is installed on the side of the top of the workbench.

[0010] The cleaning structure, located at the top of the workbench, is used to clean the surface of the cables.

[0011] A variable diameter structure is provided on the other side of the top of the workbench. The variable diameter structure includes a fixed shell fixed on the other side of the top of the workbench. A slide rail is fixed inside the fixed shell. A slider is slidably connected inside the slide rail. A movable frame is fixed at one end of the slider near the cable. A movable component is provided on one side of the fixed shell.

[0012] An ultrasonic flaw detector is fixed at the bottom of a mobile frame, and rollers that are rotatably connected to the mobile frame are provided on both sides of the ultrasonic flaw detector.

[0013] The above technical solution uses support rollers to guide the cable transport, enabling the cable to move stably along a preset path. An ultrasonic flaw detector continuously collects signals from the cable surface and interior. The collected signals are processed by the control box and transmitted to the display screen. Rollers ensure the ultrasonic flaw detector maintains a suitable detection distance from the cable surface at all times.

[0014] Furthermore, the moving component includes a rotating plate rotatably connected to one side of the fixed shell, with movable grooves provided inside one side of the rotating plate, a guide rod fixed to one side of the slider and slidably connected to the movable groove, and a pneumatic push rod rotatably connected to the rotating plate on one side of the top of the worktable.

[0015] The above technical solution uses a pneumatic push rod to extend and rotate the rotating plate, and the movable groove pushes the slider to slide through the guide rod, so that the moving frame can move and adjust the position of the ultrasonic flaw detector.

[0016] Furthermore, the sliders are distributed in a ring at equal intervals inside the fixed shell, and the rollers are symmetrically distributed on the vertical center line of the moving frame.

[0017] Through the above technical solution, the equally spaced ring-shaped sliders can drive the moving frame to move closer to or away from the cable synchronously and uniformly, so that the ultrasonic flaw detector is always in the center detection position of the cable axis. At the same time, the symmetrically distributed rollers can apply support force evenly from both sides of the cable to prevent the cable from deviating.

[0018] Furthermore, the telescopic end of the pneumatic push rod is rotatably connected to the rotating plate via a pin.

[0019] The above technical solution can smoothly convert the linear motion of the pneumatic push rod into the circular motion of the rotating plate, so as to drive the rotating plate to rotate.

[0020] Furthermore, the cleaning structure includes a cylinder fixed to the top of the workbench, a rotating cylinder rotatably connected to one side of the cylinder, brushes fixed on the inner wall of the rotating cylinder, a gear ring fixed on the outer side of the rotating cylinder, a drive motor installed on one side of the top of the cylinder, a gear meshing with the gear ring fixed at the end of the output shaft of the drive motor, and a dust discharge pipe fixed at the bottom of the cylinder.

[0021] The above technical solution uses a drive motor to rotate a gear, which in turn causes a gear ring to rotate a rotating cylinder. At the same time, the brush inside the cylinder cleans dust and impurities from the cable surface.

[0022] Furthermore, a collection box is fixed to the bottom end of the ash discharge pipe, a filter cloth is fixed inside the collection box, a negative pressure fan is fixed inside the bottom end of the collection box, and a box cover is rotatably connected to one side of the collection box.

[0023] The above technical solution involves starting a negative pressure fan to draw dust and impurities generated during cleaning into a collection box via a dust discharge pipe. The filter cloth inside the collection box then filters the dust and impurities.

[0024] Furthermore, the ash discharge pipe extends to the bottom of the workbench and is connected to the collection box, and the brushes are distributed in a ring at equal intervals inside the rotating cylinder.

[0025] Through the above technical solution, the ash discharge pipe extends to the bottom of the workbench and connects with the collection box, which can directly guide the dust and impurities generated during cleaning into the collection box, avoiding secondary pollution of the cable surface. The circularly distributed brushes can contact the cable surface in all directions, ensuring that stains in all parts are cleaned.

[0026] The above-described solution of this utility model has at least the following beneficial effects:

[0027] 1. This utility model uses a movable component to push the slider to slide, which in turn causes the movable frame to move and adjust the position of the ultrasonic flaw detector. This enables the device to adjust its size without manual operation. It can automatically adapt to different cable specifications, ensuring that the detection component always maintains the best detection posture, ensuring stable and reliable signal acquisition, and improving the device's adaptability to cables of different diameters and overall detection efficiency to a certain extent.

[0028] 2. This utility model uses a drive motor to rotate a gear, which in turn drives a rotating cylinder. Simultaneously, the brush inside the cylinder cleans dust and impurities from the cable surface, thus achieving the surface cleaning function of this device. It can thoroughly clean dust and impurities from the cable surface, preventing them from adhering to the cable surface and affecting the signal acquisition quality of subsequent testing. Moreover, the cleaning process does not require manual intervention and can be carried out synchronously with cable transportation, reducing the workload and time cost of manual cleaning.

[0037] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0038] like Figures 1 to 6 As shown, an embodiment of this utility model provides a cable condition detection device, including a workbench 1, and further comprising:

[0039] The base plate 8 is fixed to the bottom of the workbench 1, and the control box 7 is fixed to one side of the top of the base plate 8.

[0040] Support frame 2 is fixed on both sides of the top of workbench 1. Support roller 3 is rotatably connected inside support frame 2. Display screen 5 is installed on the side of the top of workbench 1.

[0041] Cleaning structure 4 is set at the top of workbench 1 and is used to clean the surface of the cable;

[0042] A variable diameter structure 6 is provided on the other side of the top of the workbench 1. The variable diameter structure 6 includes a fixed shell 607 fixed on the other side of the top of the workbench 1. A slide rail 606 is fixed inside the fixed shell 607. A slider 605 is slidably connected inside the slide rail 606. A movable frame 608 is fixed at one end of the slider 605 near the cable. A movable component is provided on one side of the fixed shell 607.

[0043] An ultrasonic flaw detector 9 is fixed at the bottom of a movable frame 608. Rollers 10 that are rotatably connected to the movable frame 608 are provided on both sides of the ultrasonic flaw detector 9.

[0044] In this embodiment of the invention, when the equipment is started, the cable is first placed on the support rollers 3 inside the support frames 2 on both sides of the top of the workbench 1. The support rollers 3 provide guidance for the cable transport by rotating on their own, so that the cable can move stably along the preset path. At the same time, the control box 7 starts to receive and process the signals fed back by each component, coordinates the operation of each part, and continuously collects signals from the surface and inside of the cable through the ultrasonic flaw detector 9. The collected signals are processed by the control box 7 and transmitted to the display screen 5, which converts the signals into visual data for presentation. The rollers 10 are in contact with the surface of the cable to provide auxiliary guidance for the movement of the cable, and at the same time, they can keep the ultrasonic flaw detector 9 at a reasonable detection distance from the surface of the cable, such as 5-15mm, to detect the condition of the cable.

[0045] like Figures 5 to 6As shown, the moving assembly includes a rotating plate 601 rotatably connected to one side of the fixed housing 607. Movable grooves 602 are provided inside one side of the rotating plate 601. A guide rod 604 that is slidably connected to the movable groove 602 is fixed to one side of the slider 605. A pneumatic push rod 603 that is connected to the rotating plate 601 is rotatably connected to one side of the top of the worktable 1. The sliders 605 are distributed in a ring at equal intervals inside the fixed housing 607. The rollers 10 are symmetrically distributed on the vertical center line of the moving frame 608. The telescopic end of the pneumatic push rod 603 is rotatably connected to the rotating plate 601 through a pin.

[0046] In this embodiment of the invention, when it is necessary to adjust the position of the ultrasonic flaw detector 9 according to the cable diameter, the control box 7 issues a command to start the pneumatic push rod 603, causing the telescopic end of the pneumatic push rod 603 to drive the rotating plate 601 to rotate. When the rotating plate 601 rotates, the movable groove 602 moves accordingly. Since one end of the guide rod 604 is fixed to the slider 605 and the other end slides inside the movable groove 602, the movable groove 602 will push the slider 605 to slide on the slide rail 606 inside the fixed shell 607 through the guide rod 604. This causes the slider 605 to drive the movable frame 608 fixed thereto to move. Then the movable frame 608 drives the ultrasonic flaw detector 9 to move and adjust its position, thereby achieving the purpose of accurately adjusting the position of the ultrasonic flaw detector 9 according to different cable diameters, which to a certain extent improves the adaptability of the equipment to cables of different specifications.

[0047] like Figures 3 to 4 As shown, the cleaning structure 4 includes a cylinder 401 fixed to the top of the workbench 1. A rotating cylinder 404 is rotatably connected to the inside of one side of the cylinder 401. Brushes 405 are fixed on the inner side wall of the rotating cylinder 404. A gear ring 406 is fixed to the outer side of the rotating cylinder 404. A drive motor 408 is installed on one side of the top of the cylinder 401. A gear 407 that meshes with the gear ring 406 is fixed to the end of the output shaft of the drive motor 408. A ash discharge pipe 409 is fixed to the bottom of the cylinder 401. A collection box 402 is fixed to the bottom of the ash discharge pipe 409. A filter cloth 410 is fixed inside the collection box 402. A negative pressure fan 411 is fixed inside the bottom of the collection box 402. A box cover 403 is rotatably connected to the inside of one side of the collection box 402. The ash discharge pipe 409 extends to the bottom of the workbench 1 and communicates with the collection box 402. The brushes 405 are distributed in a ring at equal intervals inside the rotating cylinder 404.

[0048] In this embodiment of the invention, before the cable enters the detection area of ​​the ultrasonic flaw detector 9, the drive motor 408 drives the gear 407 to rotate, which in turn drives the rotating cylinder 404 to rotate inside the cylinder 401 via the gear ring 406. When the rotating cylinder 404 rotates, the brush 405 on its inner side rotates accordingly, cleaning the dust and impurities on the surface of the cable. At the same time, the negative pressure fan 411 is started, causing the dust discharge pipe 409 to suck the dust and impurities generated during cleaning into the collection box 402. The filter cloth 410 inside the collection box 402 filters the dust and impurities, preventing them from contacting the negative pressure fan 411 and affecting the operation of the equipment. After cleaning, the cable continues to move towards the detection area of ​​the ultrasonic flaw detector 9, thereby avoiding interference from the dust and impurities on the surface of the cable to the accuracy of the signal collected by the ultrasonic flaw detector 9, and ensuring the reliability of the detection data to a certain extent. When the impurities inside the collection box 402 accumulate to a certain amount, the operator can open the box cover 403 for cleaning.

[0049] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
