[0029] 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.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4 A distribution cable defect detection device shown in the figure includes a horizontal assembly cover 1, a first adjustment ring 2 and a second adjustment ring 3, lateral assembly covers 4 are elastically assembled on both sides of the horizontal assembly cover 1, top guide wheels 5 and angle-adjustable bottom electric drive wheels 6 are installed inside the first adjustment ring 2 and the second adjustment ring 3, detachable identification devices 7 and energy storage devices 8 are symmetrically installed on both side walls of the horizontal assembly cover 1, embedded annular adjustment grooves are opened on the inner side surfaces of the horizontal assembly cover 1, and embedded combined detection modules 9 are installed inside the embedded annular adjustment grooves.

[0031] The first adjustment ring 2 and the second adjustment ring 3 are of the same size.

[0032] Working principle: Install the horizontal assembly cover 1, the first adjustment ring 2 and the second adjustment ring 3 on the distribution cable, and then use the angle-adjustable bottom electric drive wheel 6 to drive the entire device to move along the distribution cable. During the movement, the embedded combined detection module 9 is used to perform rotation detection, thereby performing a comprehensive detection of the distribution cable.

[0033] The device can also be fixed, and then the produced cable is passed through the angle-adjustable bottom electric drive wheel 6 inside the transverse assembly cover 1, the first adjustment ring 2 and the second adjustment ring 3, and detection is performed at the same time.

[0034] In order to cooperate with the bottom assembly, bottom mounting seats 10 are fixedly mounted on the assembly surfaces of the transverse assembly cover 1 and the lateral assembly cover 4 .

[0035] In order to facilitate installation and disassembly, the first adjustment ring 2 and the second adjustment ring 3 are composed of a central mounting seat 231 that cooperates with the bottom mounting seat 10, an arc-shaped clamping cover 232 elastically assembled on the two side walls of the central mounting seat 231, and locking bolts 233 threadedly assembled on both sides of the central mounting seat 231.

[0036] The upper ends of both sides of the transverse assembly cover 1 and the lateral assembly cover 4 are provided with lateral mounting frames that cooperate with the locking bolts 233. When the first adjustment ring 2 and the second adjustment ring 3 need to be installed, the arc-shaped clamping cover 232 is first flipped to both sides and put on the distribution cable, and then the assembly groove on the central mounting seat 231 is put on the bottom mounting seat 10, and then the locking bolts 233 pass through the lateral mounting frame and are screwed into both sides of the central mounting seat 231, and then continue to rotate until the bottom is squeezed on the outer side of the arc-shaped clamping cover 232, thereby completing the assembly of the first adjustment ring 2 and the second adjustment ring 3.

[0037] In order to cooperate with the internal turning adjustment, an arc-shaped turning opening 11 is opened inside the arc-shaped clamping cover 232 at the position of the angle-adjustable bottom-mounted electric drive wheel 6.

[0038] In order to cooperate with the angle adjustment and thus be suitable for translation adjustment under different states, the angle-adjustable bottom-mounted electric drive wheel 6 includes an arc-shaped mounting bracket 61 movably mounted inside the arc-shaped flipping mouth 11, an electric drive wheel 62 mounted at the end of the arc-shaped mounting bracket 61, a lateral control bracket 63 fixed on the outside of the arc-shaped mounting bracket 61 and a lateral adjustment strut 64 movably mounted on the outer surface of the arc-shaped clamping cover 232.

[0039] In order to cooperate with installation and adjustment, the embedded combined detection module 9 includes a split annular mounting seat 91 inserted into the embedded annular adjustment groove, an optical detection module 92 and an infrared temperature detection module 93 fixed on the inner arc surface of the split annular mounting seat 91, and an embedded adjustment motor 94 fixed on the side wall of the horizontal assembly cover 1.

[0040] The transverse assembly cover 1 is composed of an arc-shaped transverse cover shell and two arc-shaped closed cover shells movably mounted at the lower end of the arc-shaped transverse cover shell. The two arc-shaped closed cover shells are bolted to the arc-shaped transverse cover shell through a clamp at the upper end.

[0041] The split annular mounting seat 91 is composed of two arc-shaped mounting seat bodies of the same size respectively installed in two arc-shaped closed cover shells, and then one is installed with an optical detection module 92 and the other is installed with an infrared temperature detection module 93, and the embedded adjustment motor 94 is meshed with the side wall of the split annular mounting seat 91 through gears for transmission.

[0042] In order to facilitate installation and carrying, top mounting grooves are provided on the upper surfaces of the transverse assembly cover 1 and the lateral assembly cover 4. Top metal connecting plates 12 are welded and fixed inside the top mounting grooves on the upper surfaces of the transverse assembly cover 1 and the lateral assembly cover 4. A top handle 13 is fixedly installed on the upper end of the transverse assembly cover 1 at the outer periphery of the top mounting groove.

[0043] The top metal connecting piece 12 has a certain elasticity, so that the horizontal assembly cover 1 and the lateral assembly cover 4 are connected elastically, thereby transmitting the rigidity on the surface of the flexible distribution cable.

[0044] In order to improve the transportation stability of the distribution cable inside the transverse assembly cover 1 , an embedded guide roller 14 is installed on the inner arc surface of the transverse assembly cover 1 .

[0045] The embedded guide rollers 14 are arranged in a circular array to ensure that the spacing between the distribution cables on the inner wall of the horizontal assembly cover 1 is consistent.

[0046] When the suspended self-propelled mode is adopted, the first adjustment ring 2 and the second adjustment ring 3 are installed on the lateral assembly covers 4 on both sides. At this time, the lateral adjustment support rod 64 contracts to control the arc-shaped mounting bracket 61 to flip upward, and the electric drive wheel 62 is introduced into the inner side of the arc-shaped flipping opening 11. At this time, the electric drive wheel 62 supports the internal distribution cable from the bottom inward, and cooperates with the top guide wheel 5 to perform suspended self-propelled operation;

[0047] When the ground-mounted self-propelled vehicle is adopted, the first adjustment ring 2 and the second adjustment ring 3 are installed on both sides of the horizontal assembly cover 1, and the lateral adjustment strut 64 is extended to control the arc-shaped mounting bracket 61 to flip downward, and the electric drive wheel 62 is guided to the outside of the arc-shaped flipping mouth 11. At this time, the electric drive wheel 62 is supported and driven at the bottom, and the top guide wheel 5 cooperates with the embedded guide roller 14 to guide the internal distribution cable, and cooperates with the top guide wheel 5 to carry out ground-mounted self-propelled vehicle.

[0048] In order to assist in cleaning the debris on the surface and improve the detection accuracy of the optical detection module 92, arc-shaped mounting grooves are provided on the flat surfaces of the outer sides of the first adjustment ring 2 and the second adjustment ring 3, and the first adjustment ring 2 and the second adjustment ring 3 are fixed with a detachable lateral cleaning brush 15 through the arc-shaped mounting grooves.

[0049] A connecting strip is fixed to the connecting end of the detachable side cleaning brush 15, and the connecting strip is inserted from the loading and unloading port into the arc-shaped mounting groove to be fixedly connected to the side wall of the first adjustment ring 2 or the second adjustment ring 3. In this way, when the device moves along the cable, the detachable side cleaning brush 15 can be used to scrape off impurities on its surface.

[0050] The detachable lateral cleaning brush 15 only needs to be installed on one side.

[0051] In order to help mark the damaged point and facilitate maintenance personnel to accurately find the fault point, an embedded electric control nozzle 16 is installed on the inner curved surface of the horizontal assembly cover 1 at the assembly end of the detachable marking device 7.

[0052] When the optical detection module 92 or the infrared temperature detection module 93 detects the fault position, the embedded electric-controlled nozzle 16 will be started. At this time, the detachable marking device 7 filled with high-pressure marking liquid will be connected to the embedded electric-controlled nozzle 16, and the high-pressure marking liquid inside will be sprayed onto the cable surface on one side of the position. The position of the embedded electric-controlled nozzle 16 is staggered from the top guide wheel 5, the angle-adjustable bottom electric drive wheel 6 and the embedded guide roller 14.
