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

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The present embodiment provides an underground cable detection device with multi-environment adaptability, which can move in a pipeline for laying underground cables and detect the cables in the pipeline, thereby improving the comprehensiveness of underground cable detection and the accuracy of detection results. The device is easy to operate and reduces the difficulty of underground cable detection.

[0040] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the buried cable detection device with multi-environment adaptability includes an arc-shaped main frame 1.

[0041] Wherein, both ends of the main frame 1 are slidably equipped with elastically detachable lateral extension arms 2, and the extended ends of the elastically detachable lateral extension arms 2 are movably equipped with bottom drive wheels 7. When the buried cable detection device with multi-environment adaptability is working, the bottom drive wheel 7 can move in the pipeline when powered on, and the bottom drive wheel 7 can move on the inner bottom wall of the pipeline, and can also move on the cable at the bottom of the pipeline.

[0042] An internal flip extension frame 3 is rotatably mounted on the inner arc surface of the main frame 1, and 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 to be tested, so as to detect the cable to be tested through the cable detection module 4 mounted on the inner wall of the electrically controlled adaptive detection frame 5 close to the cable to be tested. Lateral synchronous driving wheels 82 are arranged on the two side walls of the electrically controlled adaptive detection frame 5, and the lateral synchronous driving wheels 82 are rollingly connected to the cable to be tested, and the lateral synchronous driving wheels 82 can also rotate when powered. That is, through the joint action of the lateral synchronous driving wheels 82 and the bottom driving wheels 7, the walking resistance of the buried cable detection device with multi-environment adaptability can be reduced, and the walking stability of the buried cable with multi-environment adaptability can be improved.

[0043] The side walls of the main frame 1 are movably equipped with side electric control support components 6, which include top support wheels 63. The top support wheels 63 are used to support the inner top wall of the pipeline. The top support wheels 63 and the bottom drive wheels 7 work together to improve the walking stability of the buried cable detection device with multi-environment adaptability.

[0044] For ease of understanding, the working principle of this buried cable detection device with multi-environment adaptability is briefly introduced:

[0045] First, the inspector can hold the main frame 1 and place the buried cable inspection device with multi-environment adaptability into the buried pipeline from one side opening of the buried pipeline;

[0046] Then, the inspector adjusts the two elastically separated lateral extension arms 2 according to the inner diameter of the buried pipeline, so that the bottom driving wheel 7 on the elastically separated lateral extension arm 2 supports the upper end of the bottom cable in the buried pipeline, and adjusts the side 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 driving wheel 7 form a stable support structure;

[0047] Afterwards, the internal flip extension frame 3 is rotated according to the position of the cable to be tested, so that the electrically controlled adaptive detection frame 5 approaches and surrounds the cable to be tested, and the lateral synchronous driving wheel 82 contacts the cable to be tested;

[0048] Finally, the bottom driving wheel 7 and the lateral synchronous driving wheel 82 are synchronously driven to rotate, so that the buried cable detection device with multi-environment adaptability moves from one end of the buried pipeline to the other end. In this process, the cable detection module 4 arranged on the inner wall of the adaptive detection frame 5 will detect the cable to be detected. Optionally, three cable detection modules 4 can be arranged on the circumference of the adaptive detection frame 5 to perform three-point optical detection on the periphery of the cable to be detected.

[0049] The cable detection device with multi-environment adaptability provided in this embodiment can perform close-range detection of the cable outer sheath, and the detection result has high accuracy. In addition, it is suitable for detecting cables inside pipelines with very small diameters or insufficient reserved space, reducing the difficulty of cable detection in a small space.

[0050] Furthermore, if Figure 1 , Figure 2 and Figure 4 As shown, arc-shaped adjustment grooves 9 are provided at both ends of the main frame 1, and the first opening of the arc-shaped adjustment groove 9 is located at the end of the main frame 1. The elastically detachable lateral extension arm 2 includes an arc-shaped extension arm 21, and one end of the arc-shaped extension arm 21 is slidably assembled in 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 surface of the main frame 1, and the outer arc surface of the main frame 1 is close to the two sides of the second opening 91 and presses on the two ends of the arc-shaped extension arm 21. Through the connection between the arc-shaped adjustment groove 9 and the arc-shaped extension arm 21, the sliding assembly of the elastically detachable lateral extension arm 2 and the main frame 1 is realized, and the structure is simple and easy to process. In addition, by setting the second opening 91 as a "shrinking" structure, the outer arc 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, continue to see Figure 1 , Figure 2 and Figure 4In order to lock the arc-shaped extension arm 21 at a certain position inside the arc-shaped adjustment groove 9, the reliability of the extension length adjustment of the elastically separated lateral extension arm 2 is ensured. In this embodiment, an arc-shaped locking opening 92 is provided on the bottom wall of the arc-shaped adjustment groove 9, and the lateral locking bolt 15 passes through the arc-shaped extension arm 21 located at the second opening 91 and the arc-shaped locking opening 92 is connected to the locking nut.

[0052] Optionally, the lateral locking bolt 15 can be threadedly connected to the arc-shaped extension arm 21 .

[0053] Further, see Figure 1 and Figure 2 The elastically separated lateral extension arm 2 further includes a first flip base frame 22 , a second flip base frame 23 and a central extrusion spring sheet 24 .

[0054] The first flip chassis 22 and the second flip chassis 23 are movably mounted at the bottom ends of both sides of the arc-shaped extension arm 21, and the middle section of the central extrusion spring 24 is fixed inside the arc-shaped extension arm 21, and the two ends are respectively connected to the first flip chassis 22 and the second flip chassis 23. The first flip chassis 22 and the second flip chassis 23 are both provided with bottom driving wheels 7.

[0055] When the arc extension arm 21 is pulled outward, the first flip chassis 22 and the second flip chassis 23 at the bottom of the arc extension arm 21 will be squeezed laterally by the central squeezing spring 24. When the first flip chassis 22 and the second flip chassis 23 form a support at the bottom of the arc extension arm 21 and the bottom driving wheels 7 on the first flip chassis 22 and the second flip chassis 23 are supported on the two side cables at the bottom of the buried pipeline, stop pulling the arc extension arm 21, rotate and lock the lateral locking bolts 15, and increase the friction between the bottom driving wheel 7 and the cable surface through the dead weight of the entire device, so as to ensure that it can be stably driven in translation. The central squeezing spring 24 can control the elastic reset of the first flip chassis 22 and the second flip chassis 23, and can also prevent the first flip chassis 22 and the second flip chassis 23 from over-flipping.

[0056] Optionally, both the first flip base 22 and the second flip base 23 are provided with inner mounting frames, and the two ends of the central extrusion spring piece 24 are respectively inserted into the inner mounting frames of the first flip base 22 and the second flip base 23. By adjusting the length of the central extrusion spring piece 24 inserted into the inner mounting frame, excessive flipping of the first flip frame 22 and the second flip frame 23 can be effectively avoided.

[0057] Furthermore, if 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 member 34 .

[0058] Among them, one end of the inner flip arm 31 is rotatably connected to the inner arc surface of the main frame 1, and an electric control adjustment 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 electric control adjustment screw 32 is threadedly connected to the threaded hole on the outer extension sleeve 33. In this way, the outer extension sleeve 33 can slide on the inner flip arm 31 by driving the electric control adjustment screw 32 to rotate by a motor; the electric control type adaptive detection frame 5 is fixedly assembled at the end of the outer extension sleeve 33. One end of the angle adjustment member 34 is connected to the inner arc surface of the main frame 1, and the other end is connected to the inner flip arm 31, which is used to adjust the flip angle of the inner flip arm 31, so that the electric control type adaptive detection frame 5 can be rotated to the cable to be tested to detect the cable to be tested.

[0059] Optionally, the external extension sleeve 33 can be threadedly assembled with the electric control adjustment screw 32 through the internal thread adjustment block on the inner wall, and the electric control adjustment screw 32 is rotated to control the external extension sleeve 33 to slide and adjust on the outside of the inner flip arm 31.

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

[0061] Optionally, in a possible embodiment, the angle adjustment member 34 is a cylinder. In other embodiments, the angle adjustment member 34 may also be a telescopic rod, which can be set according to actual needs, and this application does not make specific limitations.

[0062] In order to cooperate with the 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 flip arm 31 is rotatably connected to the inner mounting groove.

[0063] For ease of understanding, the working principle of the internal flip extension frame 3 is briefly introduced:

[0064] First, the angle of the inner flip arm 31 is adjusted by the angle adjustment member 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, the electrically controlled adjusting screw rod 32 is controlled to rotate, so that the outer extension sleeve 33 slides on the inner flip arm 31, and drives the electrically controlled adaptive detection frame 5 to approach the cable to be tested;

[0066] Finally, when the electrically controlled adaptive detection frame 5 moves to the right position, the electrically controlled adaptive detection frame 5 surrounds the cable to be tested, and the lateral synchronous driving wheels 82 on the two side walls of the electrically controlled adaptive detection frame 5 contact the cable to be tested.

[0067] In order to cooperate with the adaptive adjustment, the electrically controlled adaptive detection frame 5 includes a first arc detection cover 51 fixedly mounted at the end of the external extension sleeve 33, and a first arc adjustment cover 52 and a second arc adjustment cover 53 slidably mounted on both sides of the first arc detection cover 51. In this way, by adjusting the extension length of the first arc adjustment cover 52 and the second arc adjustment cover 53 relative to the first arc detection cover 51, it is possible to match cables to be tested with different diameters, thereby improving the universality of the buried cable detection device with multi-environment adaptability.

[0068] Furthermore, if Figure 3 As shown, in order to realize the automatic adjustment of the electrically controlled adaptive detection frame 5, in this embodiment, arc-shaped inner telescopic grooves 10 for slidingly assembling the first arc-shaped adjustment cover 52 and the second arc-shaped adjustment cover 53 are provided at both ends of the first arc-shaped detection cover 51, and an internal adjustment groove 11 connecting the two arc-shaped inner telescopic grooves 10. The ends of the first arc-shaped adjustment cover 51 and the second arc-shaped adjustment cover 52 that are close to each other are both provided with arc-shaped racks 13, and the two arc-shaped racks 13 are arranged in the internal adjustment groove 11 at intervals. A built-in adjustment motor 54 is installed inside the external extension sleeve 33. The bottom output shaft of the built-in 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 such arrangement, when the built-in adjusting motor 54 is controlled to rotate, the first arc-shaped adjusting cover 52 and the second arc-shaped adjusting cover 53 can be synchronously extended and retracted, thereby adjusting the sliding of the first arc-shaped adjusting cover 52 and the second arc-shaped adjusting cover 53 inside the arc-shaped inner telescopic groove 10.

[0069] Specifically, when in use, the electrically controlled adjusting screw rod 32 and the angle adjusting member 34 are controlled to move the electrically controlled adaptive detection frame 5 to the periphery of the cable to be tested. When the external extension sleeve 33 drives the first arc-shaped detection cover 51 to extend to one side of the cable to be tested, the built-in adjustment motor 54 is started, and the first arc-shaped adjustment cover 52 and the second arc-shaped adjustment cover 53 on both sides of the first arc-shaped detection cover 51 are driven to extend outward through the output gear 12 and the arc-shaped racks 13 on the first arc-shaped adjustment cover 52 and the second arc-shaped adjustment cover 53 to surround the cable to be tested on the inside.

[0070] Optionally, the cable detection module 4 can be arranged on the first arc detection cover 51, the first arc adjustment cover 52 and the second arc adjustment cover 53, and the detection is more comprehensive through the cable detection modules 4 at three points. In addition, the lateral synchronous driving wheels 82 on both sides of the electrically controlled adaptive detection frame 5 can ensure that the detection distance between the outer wall of the cable to be tested and the three cable detection modules 4 is consistent, and the bottom driving wheel 7 can be used to synchronously drive the buried cable detection device with multi-environment adaptability to move on the inside and outside.

[0071] Further, see Figure 3 In order to install the cable detection module 4, a lateral boss 14 protruding outward for installing the cable detection module 4 can be provided on the inner arc surface of the first arc detection cover 51, the first arc adjustment cover 52 and the second arc adjustment cover 53.

[0072] In addition, arc-shaped notches connected to the corresponding arc-shaped inner telescopic grooves 10 are provided at both ends of the inner arc-shaped surface of the first arc-shaped detection cover 51, and the arc-shaped notches cooperate with the corresponding lateral bosses 14 to avoid interference with the lateral bosses 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 can be an integral structure with the first arc-shaped adjustment cover 52 for easy 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, continue to see Figure 3 In order to improve the optical detection accuracy, a detachable lateral bracket 81 is provided on the first arc detection cover 51, the first arc adjustment cover 52 and the second arc adjustment cover 53, and each detachable lateral bracket 81 is provided with a lateral synchronous driving wheel 82. In this embodiment, the detachable lateral bracket 81 and the lateral synchronous driving wheel 82 constitute a lateral driving assembly 8.

[0075] Optionally, the detachable lateral bracket 81 is fixed to the first arc detection cover 51, the first arc adjustment cover 52 and the second arc adjustment cover 53 by bolts. The installation position of the lateral synchronous driving wheel 82 inside the detachable lateral bracket 81 is adjusted according to the outer diameter specification of the cable to be tested, so as to ensure that the cable to be tested is located at the center position of the first arc detection cover 51, the first arc adjustment cover 52 and the second arc adjustment cover 53.

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

[0077] Optionally, the outer flip member 62 can control the flip angle of the arc-shaped flip frame 61 by telescoping 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 flip member 62 may be a cylinder, or a telescopic rod, etc., and may be configured according to actual needs, and this application does not make any specific limitation.

[0079] The present application adopts a manual method to ensure the extension length of the arc extension arm 21, and uses an electronic level set on the main frame 1 for control, so as to control the angle of the arc flip frame 61 through the outer flip member 62, thereby ensuring that the supporting force with the inner wall of the buried pipeline is automatically adjusted when the cable heights on both sides of the bottom surface are inconsistent.
