Description

Technical Field

[0001] This invention relates to the field of cable testing technology, and in particular to a buried cable testing device with multi-environment adaptability. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors. Its primary function is to transmit electrical energy and signals. Traditional cable laying methods mainly include overhead installation and underground burial. Each method has its advantages and disadvantages. While overhead installation is simple and efficient, it significantly impacts urban layout and aesthetics, and can also hinder urban development. Underground burial, due to its limited internal space, greatly restricts manual operation, especially for laying long conduits, significantly increasing the difficulty and cost of later maintenance.

[0003] Currently, most equipment on the market for inspecting buried cables uses end-connection inspection equipment or manual entry into the pipe for inspection. While end-connection inspection equipment is convenient, this method cannot perform close-range inspection of the cable's outer sheath, and manual inspection cannot be carried out inside pipes with small diameters or insufficient space. In addition, the operation of inspecting internal cables is very troublesome. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the equipment currently available on the market for detecting buried cables cannot detect them at close range, and their applicability is relatively limited, and the detection operation is cumbersome.

The bottom drive wheel is provided on both the first flip base frame and the second flip base frame.

[0013] Optionally, the internal flip-up extension frame includes:

[0014] An inner tilting arm is rotatably connected at one end to the inner arc-shaped surface of the main frame, and an electrically controlled adjusting screw is provided inside the inner tilting arm.

[0015] An outer extension sleeve is slidably sleeved on the outer side of the other end of the inner flip arm. The electrically controlled adjusting screw is threadedly connected to the threaded hole on the outer extension sleeve. The end of the outer extension sleeve is fixedly fitted with the electrically controlled adaptive detection frame.

[0016] An angle adjustment component has one end connected to the inner arc-shaped surface of the main frame and the other end connected to the inner flip arm. The angle adjustment component is used to adjust the flip angle of the inner flip arm.

[0017] Optionally, the electrically controlled adaptive detection frame includes a first arc-shaped detection cover fixedly installed at the end of the outer extension sleeve, and a first arc-shaped adjustment cover and a second arc-shaped adjustment cover slidably assembled on both sides of the first arc-shaped detection cover.

[0018] Optionally, the first arc-shaped detection cover has arc-shaped inner telescopic grooves at both ends for slidingly assembling the first arc-shaped adjustment cover and the second arc-shaped adjustment cover, and an internal adjustment groove connecting the two arc-shaped inner telescopic grooves. The ends of the first arc-shaped adjustment cover and the second arc-shaped adjustment cover that are close to each other are provided with arc-shaped racks, and the two arc-shaped racks are spaced apart in the internal adjustment groove.

[0019] An internal adjustment motor is installed inside the external extension sleeve. The output shaft at the bottom of the internal adjustment motor extends into the internal adjustment groove.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0038] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] This embodiment provides a buried cable inspection device with multiple environmental adaptability. It can move inside the duct where buried cables are laid and inspect the cables inside the duct, which improves the comprehensiveness of buried cable inspection and the accuracy of the inspection results. Moreover, it is simple to operate and reduces the difficulty of inspecting buried cables.

[0040] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the underground cable inspection device with multiple environmental adaptability includes an arc-shaped main frame 1.

[0041] The main frame 1 has elastically separable lateral extension arms 2 slidably mounted at both ends, and bottom drive wheels 7 are movably mounted at the extended ends of the elastically separable lateral extension arms 2. When this multi-environmentally adaptable buried cable detection device is in operation, the bottom drive wheels 7 can move inside the pipe when energized. The bottom drive wheels 7 can move on the inner bottom wall of the pipe or on the cable located at the bottom of the pipe.

[0042] An internal flip-extension frame 3 is rotatably mounted on the inner arc-shaped surface of the main frame 1. An electrically controlled adaptive detection frame 5 is fixedly mounted on the bottom protruding end of the internal flip-extension frame 3. The electrically controlled adaptive detection frame 5 can surround the cable under test, allowing the cable detection module 4 mounted on the inner wall of the electrically controlled adaptive detection frame 5 close to the cable under test to perform detection. Lateral synchronous drive wheels 82 are provided on both side walls of the electrically controlled adaptive detection frame 5, and are rotatably connected to the cable under test. The lateral synchronous drive wheels 82 can also rotate when energized. That is, through the combined action of the lateral synchronous drive wheels 82 and the bottom drive wheel 7, the walking resistance of this multi-environment adaptable buried cable detection device can be reduced, improving the walking stability of the multi-environment adaptable buried cable.

[0043] Side-mounted electrical control support assemblies 6 are movably mounted on both side walls of the main frame 1. Each side-mounted electrical control support assembly 6 includes a top support wheel 63. The top support wheel 63 is used to support the inner top wall of the pipe. The top support wheel 63, together with the bottom drive wheel 7, improves the walking stability of this multi-environmentally adaptable buried cable inspection device.

[0044] To facilitate understanding, the working principle of this multi-environmentally adaptable underground cable detection device will be briefly introduced below:

[0045] First, the inspector can hold the main frame 1 and insert the multi-environmentally adaptable underground cable inspection device into the underground pipeline from one side opening.

[0046] Then, the inspectors adjusted the two elastically separated lateral extension arms 2 according to the inner diameter of the buried pipeline, so that the bottom drive wheel 7 on the elastically separated lateral extension arm 2 supports the upper end of the bottom cable in the buried pipeline, and adjusted the side-mounted electric control support assembly 6 so that the top support wheel 63 supports the top of the buried pipeline, so that the top support wheel 63 and the bottom drive wheel 7 form a stable support structure.

[0047] Then, the internal flip extension frame 3 is rotated according to the position of the cable under test, so that the electronically controlled adaptive detection frame 5 approaches and surrounds the cable under test, and the lateral synchronous drive wheel 82 contacts the cable under test.

[0048] Finally, the bottom drive wheel 7 and the side synchronous drive wheel 82 are synchronously driven to rotate, causing the multi-environmentally adaptable buried cable detection device to move from one end of the buried pipeline to the other. During this process, the cable detection module 4 installed on the inner wall of the adaptive detection frame 5 will detect the cable under test. Optionally, three cable detection modules 4 can be installed around the circumference of the adaptive detection frame 5 to perform three-point optical detection on the periphery of the cable under test.

[0049] The cable testing device with multi-environment adaptability provided in this embodiment can perform close-range testing of the cable outer sheath, with high accuracy of the testing results. Furthermore, it is suitable for testing cables inside pipes with very small diameters or insufficient reserved space, reducing the difficulty of cable testing in confined spaces.

[0050] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, both ends of the main frame 1 are provided with arc-shaped adjustment grooves 9. The first opening of the arc-shaped adjustment groove 9 is located at the end of the main frame 1. The elastically separable lateral extension arm 2 includes an arc-shaped extension arm 21, one end of which is slidably fitted into the arc-shaped adjustment groove 9 through the first opening. The second opening 91 of the arc-shaped adjustment groove 9 is located on the outer arc-shaped surface of the main frame 1, and the outer arc-shaped surface of the main frame 1 presses against the two ends of the arc-shaped extension arm 21 near the second opening 91. Through the connection between the arc-shaped adjustment groove 9 and the arc-shaped extension arm 21, the sliding assembly of the elastically separable lateral extension arm 2 and the main frame 1 is realized. The structure is simple and easy to process. Furthermore, by setting the second opening 91 as a "recessed" structure, the outer arc-shaped surface of the main frame 1 can limit the arc-shaped extension arm 21, reducing the risk of the arc-shaped extension arm 21 falling off.

[0051] Optionally, see [link to relevant documentation] Figure 1 , Figure 2 and Figure 4To ensure the reliability of the extension length adjustment of the elastically separable lateral extension arm 21, the arc-shaped adjustment groove 9 has an arc-shaped locking port 92 on its bottom wall. A lateral locking bolt 15 passes through the arc-shaped extension arm 21 located at the second opening 91 and is connected to the locking nut via the arc-shaped locking port 92.

[0052] Optionally, the lateral locking bolt 15 can be threaded onto the arc-shaped extension arm 21.

[0053] Further, see also Figure 1 and Figure 2 The elastic split lateral extension arm 2 also includes a first flip base 22, a second flip base 23, and a centrally located compression spring 24.

[0054] The first flipping base 22 and the second flipping base 23 are movably mounted on the bottom ends of both sides of the arc-shaped extension arm 21, while the middle section of the centrally located compression spring 24 is fixed to the inner side of the arc-shaped extension arm 21, with both ends connected to the first flipping base 22 and the second flipping base 23 respectively. Both the first flipping base 22 and the second flipping base 23 are equipped with bottom drive wheels 7.

[0055] When the arc-shaped extension arm 21 is pulled outward, the first flip base frame 22 and the second flip base frame 23 at the bottom of the arc-shaped extension arm 21 will be subjected to lateral compression by the central compression spring 24. When the first flip base frame 22 and the second flip base frame 23 form a support at the bottom of the arc-shaped extension arm 21 and the bottom drive wheels 7 on the first flip base frame 22 and the second flip base frame 23 are supported on the cables on both sides at the lowest end of the buried pipeline, the pulling of the arc-shaped extension arm 21 is stopped, and the lateral locking bolt 15 is rotated and tightened. The friction between the bottom drive wheel 7 and the cable surface is increased by the weight of the entire device, thereby ensuring that it can be stably driven to move horizontally. The central compression spring 24 can control the elastic return of the first flip base frame 22 and the second flip base frame 23, and can also prevent the first flip base frame 22 and the second flip base frame 23 from over-flipping.

[0056] Optionally, both the first flipping base 22 and the second flipping base 23 are provided with inner mounting frames. The two ends of the central compression spring 24 are respectively inserted into the inner mounting frames of the first flipping base 22 and the second flipping base 23. By adjusting the length of the central compression spring 24 inserted into the inner mounting frame, the first flipping frame 22 and the second flipping frame 23 can be effectively prevented from flipping excessively.

[0057] Furthermore, such as Figure 2 and Figure 3 As shown, the internal flip-extension frame 3 includes an inner flip arm 31, an outer extension sleeve 33, and an angle adjustment component 34.

[0058] One end of the inner flip arm 31 is rotatably connected to the inner arc-shaped surface of the main frame 1, and an electrically controlled adjusting screw 32 is provided inside the inner flip arm 31. The outer extension sleeve 33 is slidably sleeved on the outer side of the other end of the inner flip arm 31, and the electrically controlled adjusting screw 32 is threadedly connected to a threaded hole on the outer extension sleeve 33. With this configuration, the outer extension sleeve 33 can slide on the inner flip arm 31 by rotating the electrically controlled adjusting screw 32 driven by a motor. The electrically controlled adaptive detection frame 5 is fixedly assembled on the end of the outer extension sleeve 33. One end of the angle adjusting component 34 is connected to the inner arc-shaped surface of the main frame 1, and the other end is connected to the inner flip arm 31. It is used to adjust the flip angle of the inner flip arm 31, so that the electrically controlled adaptive detection frame 5 can rotate to the cable under test for detection.

[0059] Optionally, the outer extension sleeve 33 can be threadedly assembled with the electrically controlled adjusting screw 32 via an internal threaded adjusting block on the inner wall, and the rotation of the electrically controlled adjusting screw 32 can be used to control the sliding adjustment of the outer extension sleeve 33 on the outside of the inner flip arm 31.

[0060] Optionally, the angle adjustment member 34 can control the flipping angle of the inner flipping arm 31 by telescoping, so that the inner flipping extension frame 3 can be aligned with the cable to be tested.

[0061] Optionally, in one possible embodiment, the angle adjusting member 34 is a cylinder. In other embodiments, the angle adjusting member 34 may also be a telescopic rod, whichever is required, and this application does not impose any specific limitations.

[0062] To facilitate flipping and telescopic adjustment, an inner mounting groove can be opened on the inner arc surface of the main frame 1, and one end of the inner flipping arm 31 is rotatably connected to the inner mounting groove.

[0063] To facilitate understanding, the working principle of the internal flip-out extension frame 3 will be briefly introduced below:

[0064] First, the angle of the inner flip arm 31 is adjusted by the angle adjustment component 34, so that the inner flip arm 31 drives the outer extension sleeve 33 and the electrically controlled adaptive detection frame 5 fixedly mounted on the outer extension sleeve 33 to rotate until the electrically controlled adaptive detection frame 5 is facing the cable to be tested.

[0065] Then, control the rotation of the electronically controlled adjusting screw 32 so that the outer extension sleeve 33 slides on the inner flip arm 31 and drives the electronically controlled adaptive detection frame 5 to approach the cable under test.

[0066] Finally, after the electrically controlled adaptive detection frame 5 moves into position, it surrounds the cable under test and makes the lateral synchronous drive wheels 82 on both sides of the electrically controlled adaptive detection frame 5 contact the cable under test.

[0067] To facilitate adaptive adjustment, the electrically controlled adaptive detection frame 5 includes a first arc-shaped detection cover 51 fixedly mounted on the end of the external extension sleeve 33, and a first arc-shaped adjustment cover 52 and a second arc-shaped adjustment cover 53 slidably mounted on both sides of the first arc-shaped detection cover 51. This configuration allows for the adjustment of the extension length of the first arc-shaped adjustment cover 52 and the second arc-shaped adjustment cover 53 relative to the first arc-shaped detection cover 51, enabling the testing of cables with different diameters and improving the versatility of this multi-environmentally adaptable buried cable testing device.

[0068] Furthermore, such as Figure 3 As shown, in order to achieve automatic adjustment of the electrically controlled adaptive detection frame 5, in this embodiment, the first arc-shaped detection cover 51 has arc-shaped inner telescopic grooves 10 at both ends for sliding assembly of the first arc-shaped adjustment cover 52 and the second arc-shaped adjustment cover 53, and an internal adjustment groove 11 connecting the two arc-shaped inner telescopic grooves 10. Arc-shaped racks 13 are provided at the ends of the first arc-shaped adjustment cover 52 and the second arc-shaped adjustment cover 53 that are close to each other, and the two arc-shaped racks 13 are spaced apart within the internal adjustment groove 11. An internal adjustment motor 54 is installed inside the external extension sleeve 33. The bottom output shaft of the internal adjustment motor 54 extends into the internal adjustment groove 11, and an output gear 12 is fixed on the bottom output shaft. The output gear 12 is located between the two arc-shaped racks 13 and meshes with the two arc-shaped racks 13. With this configuration, when the built-in regulating motor 54 is rotated, the first arc-shaped regulating cover 52 and the second arc-shaped regulating cover 53 can be extended and retracted synchronously, thereby adjusting the sliding of the first arc-shaped regulating cover 52 and the second arc-shaped regulating cover 53 inside the arc-shaped inner telescopic groove 10.

[0069] Specifically, during use, the electronically controlled adjusting screw 32 and angle adjusting component 34 are controlled to move the electronically controlled adaptive detection frame 5 to the periphery of the cable under test. When the external extension sleeve 33 drives the first arc-shaped detection cover 51 to extend to one side of the cable under test, the built-in adjusting motor 54 is started. Through the output gear 12 and the arc rack 13 on the first arc-shaped adjusting cover 52 and the second arc-shaped adjusting cover 53, the first arc-shaped adjusting cover 52 and the second arc-shaped adjusting cover 53 on both sides of the first arc-shaped detection cover 51 are driven to extend outward, surrounding the cable under test on the inner side.

[0070] Optionally, cable detection modules 4 can be installed on the first arc-shaped detection cover 51, the first arc-shaped adjustment cover 52, and the second arc-shaped adjustment cover 53. The cable detection modules 4 at three points work together to provide comprehensive detection. Furthermore, the lateral synchronous drive wheels 82 on both sides of the electrically controlled adaptive detection frame 5 ensure that the outer wall of the cable under test is at the same detection distance as the three cable detection modules 4. Simultaneously, the bottom drive wheels 7 can synchronously drive the movement of this multi-environmentally adaptable buried cable detection device from both the inner and outer sides.

[0071] Further, see also Figure 3 For the installation of the cable detection module 4, outwardly protruding lateral bosses 14 for installing the cable detection module 4 can be provided on the inner arc surfaces of the first arc-shaped detection cover 51, the first arc-shaped adjustment cover 52 and the second arc-shaped adjustment cover 53.

[0072] Furthermore, both ends of the inner arc surface of the first arc-shaped detection cover 51 are provided with arc-shaped notches that communicate with the corresponding arc-shaped inner telescopic groove 10. The arc-shaped notches cooperate with the corresponding lateral protrusions 14 to avoid interfering with the lateral protrusions 14 when the first arc-shaped adjustment cover 52 and the second arc-shaped adjustment cover 53 slide and retract.

[0073] Optionally, the arc-shaped rack 13 on the first arc-shaped adjustment cover 52 and the first arc-shaped adjustment cover 52 can be an integral structure, which is convenient for processing. Similarly, the arc-shaped rack 13 on the second arc-shaped adjustment cover 53 can also be an integral structure with the second arc-shaped adjustment cover 53.

[0074] Optionally, see [link to relevant documentation] Figure 3 To improve optical detection accuracy, detachable lateral supports 81 are provided on the first arc-shaped detection cover 51, the first arc-shaped adjustment cover 52, and the second arc-shaped adjustment cover 53. Each detachable lateral support 81 is equipped with a lateral synchronous drive wheel 82. In this embodiment, the detachable lateral supports 81 and the lateral synchronous drive wheels 82 constitute a lateral drive assembly 8.

[0075] Optionally, the detachable lateral support 81 is fixed to the first arc-shaped detection cover 51, the first arc-shaped adjustment cover 52, and the second arc-shaped adjustment cover 53 by bolts. The installation position of the lateral synchronous drive wheel 82 inside the detachable lateral support 81 is adjusted according to the outer diameter specification of the cable under test, thereby ensuring that the cable under test is located at the center position of the first arc-shaped detection cover 51, the first arc-shaped adjustment cover 52, and the second arc-shaped adjustment cover 53.

[0076] To accommodate the lateral tilting support, the side-mounted electrically controlled support assembly 6 also includes an arc-shaped tilting frame 61 rotatably mounted on the side wall of the main frame 1 and an outer tilting member 62 for controlling the rotation angle of the arc-shaped tilting frame 61. The end of the arc-shaped tilting frame 61 is provided with a top support wheel 63. One end of the outer tilting member 62 is connected to the side wall of the main frame 1, and the other end is connected to the arc-shaped tilting frame 61.

[0077] Optionally, the outer flipping component 62 can control the flipping angle of the arc-shaped flipping frame 61 by telescopic extension, so as to support the top support wheel 63 on the inner wall of the buried pipe, ensuring that the buried cable detection device with multi-environment adaptability can be adapted to buried pipes of different diameters.

[0078] Optionally, the outer flipping component 62 can be a cylinder or a telescopic rod, etc., depending on actual needs. This application does not make any specific limitations.

[0079] This application uses a manual method to ensure the extension length of the arc-shaped extension arm 21. It uses an electronic level set on the main frame 1 for control, thereby controlling the angle of the arc-shaped flip frame 61 through the outer flip part 62, so as to automatically adjust the support force with the inner wall of the buried pipe when the cable heights on both sides of the bottom surface are inconsistent.

[0080] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
