[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figures 1 - 3 , an embodiment provided by the present invention: A transmission line inspection device includes a body 1. A support frame 2 is fixedly connected to the top of the body 1. A support block 3 is fixedly connected inside the support frame 2. A rotating column 4 is rotatably connected inside the support block 3. A first pulley 5 is fixedly connected to the outer wall of the rotating column 4. A slider 6 is slidably connected inside the support frame 2. A driving motor 7 is fixedly connected to one side of the slider 6. A transmission column 8 is fixedly connected to the output end of the driving motor 7. A second pulley 9 is fixedly connected to the outer wall of the transmission column 8. A support column 10 is fixedly connected inside the support frame 2. The slider 6 is slidably connected to the outer wall of the support column 10. A spring 11 is sleeved on the outer wall of the support column 10. The top end of the spring 11 is fixedly connected inside the support frame 2. The bottom end of the spring 11 is fixedly connected to the top of the slider 6. A detection component is arranged at the bottom of the body 1. The detection component is used to inspect the line. Two symmetrically arranged connecting columns 12 are fixedly connected to the top of the body 1. Guide wheels 13 are rotatably connected to the outer walls of the connecting columns 12.

[0033] Specifically, when using this line inspection device, first pass the cable through between the clamping blocks 22 and introduce it between the first pulley 5 and the second pulley 9. When the second pulley 9 touches the cable, it moves under force, driving the transmission column 8 and the slider 6 to slide inside the support frame 2. At the same time, the slider 6 is forced to squeeze the support column 10 connected to the top, causing it to contract, so that the cable passes between the second pulley 9 and the first pulley 5, and then passes through between the two guide wheels 13 and is led out from the other side of the second pulley 9 and the first pulley 5. Hang the device on the cable. The unloading and rebounding action of the support column 10 drives the slider 6 and the transmission column 8 to reset, making the second pulley 9 closely adhere to the outer wall of the cable. Then, the output end of the driving motor 7 drives the transmission column 8 to rotate, and the transmission column 8 drives the second pulley 9 to rotate, thereby pushing the device to move, enabling the device to move smoothly on cables of different sizes and ensuring the stable movement and safe operation of the device during the inspection process.

[0034] Referring to Figure 1 , the detection component includes a double-headed motor 23. The double-headed motor 23 is fixedly connected to the bottom of the body 1. Camera 24 is fixedly connected to both output ends of the double-headed motor 23.

[0035] Specifically, during the mobile inspection process, the device can drive the camera 24 to rotate through the output end of the dual-head motor 23, thereby adjusting the angle of the camera 24 to detect the line comprehensively. The function of the dual-head motor 23 is to provide rotational power through its output end, enabling the camera 24 to change its viewing angle when necessary to capture detailed conditions of all aspects of the line, ensuring comprehensive coverage and detailed line inspection.

[0036] Refer to Figure 1 Figure 2 and Figure 4 On the top of the body 1, a fixing frame 14 is fixedly connected. On one side of the fixing frame 14, a fixing column 19 is fixedly connected. On the top of the fixing frame 14, a cylinder 15 is fixedly connected. The output end of the cylinder 15 is fixedly connected with a support rod 16. A sliding column 17 is slidably connected inside the support rod 16. The outer wall of the sliding column 17 is rotatably connected with a connecting rod 18. The connecting rod 18 is rotatably connected to the outer wall of the fixing column 19. Inside one side of the connecting rod 18, a rotating shaft 20 is rotatably connected. A connecting block 21 is fixedly connected to the outer wall of the rotating shaft 20. A clamping block 22 is fixedly connected to one side of the connecting block 21.

[0037] Specifically, when the cable passes through between the clamping blocks 22, the output end of the cylinder 15 drives the support rod 16 to move. The function of the cylinder 15 is to control the movement of the support rod 16 through air pressure, thereby initiating the cable clamping action of the entire device. The support rod 16 transmits force to the internal sliding column 17, causing the sliding column 17 to start moving. The movement of the sliding column 17 further drives the connecting rod 18 connected to the outer wall to move. The connecting rod 18 rotates around the outer wall of the fixing column 19 under the action of force. At the same time, the connecting rod 18 also drives the rotating shaft 20 to move. The movement of the rotating shaft 20 pushes the connecting block 21 connected to the outer wall to move. The connecting block 21 drives the clamping block 22 connected to one side to start moving under force, enabling the two clamping blocks 22 to clamp the outer wall of the cable, ensuring that the device can adapt to and hang on cables of various sizes during operation, and guaranteeing the stability and reliability of the inspection device.

[0038] Working principle: When using this line inspection device, first pass the cable through between the clamping blocks 22 and introduce it between the second pulley 9 and the first pulley 5. When the second pulley 9 comes into contact with the cable, it will move under force, thereby driving the transmission column 8 and the slider 6 to slide inside the support frame 2. At the same time, the slider 6 exerts force on the support column 10 connected to the top, causing it to contract, so that the cable passes through between the second pulley 9 and the first pulley 5, and then passes the cable through between the two guide wheels 13 and leads it out from between the second pulley 9 and the first pulley 5 on the other side, making the device hang on the cable. At the same time, it rebounds by unloading force through the support column 10, thereby driving the slider 6 and the transmission column 8 to reset, making the second pulley 9 tightly fit on the outer wall of the cable. Subsequently, the output end of the driving motor 7 drives the transmission column 8 to rotate, and the transmission column 8 drives the second pulley 9 to rotate under force, so that the device moves, achieving the effect that the device can move smoothly on cables of different sizes. During the movement, the output end of the double-headed motor 23 can drive the camera 24 to rotate, thereby adjusting the angle of the camera 24 to facilitate the detection of the line. When the cable passes through between the clamping blocks 22, the output end of the cylinder 15 can drive the support rod 16 to move. The support rod 16 drives the sliding column 17 inside it to move. The sliding column 17 drives the connecting rod 18 connected to the outer wall to move, making the connecting rod 18 rotate on the outer wall of the fixed column 19 under force. At the same time, the connecting rod 18 also drives the rotating shaft 20 to move. The rotating shaft 20 drives the connecting block 21 connected to the outer wall to move. The connecting block 21 drives the clamping block 22 connected to one side to move, making the two clamping blocks 22 buckle on the outer wall of the cable, achieving the effect of being able to hang on cables of different sizes.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
