A stop block 12 is fixedly installed at one end of the guiding wheel 6, and the stop block 12 can be installed on the guiding wheel 6 by bolts or riveting to prevent the cable from detaching from the guiding wheel 6 during operation.

[0026] Please refer to Figures 1-5 , a positioning rod 7 is opened on the surface of the base 1, and the positioning rod 7 is slidably connected to the base 1, allowing the positioning rod 7 to freely slide on the base 1 to meet the requirements of different positions. The sliding connection can be realized by a sliding groove or a track. A pull handle 8 is fixedly installed at one end of the positioning rod 7. The material of the pull handle 8 is PP plastic. PP plastic not only has a light weight, but also has good mechanical strength and chemical corrosion resistance, and is suitable for use in outdoor environments. The pull handle 8 is connected to the positioning rod 7 through a tension spring 9. The tension spring 9 can be made of stainless steel or alloy materials to provide sufficient pulling force and durability. The function of the tension spring 9 is to automatically pull the positioning rod 7 back to the initial position after the pull handle 8 is released, realizing the automatic locking function. Positioning holes 10 are opened on the surface of the plug board 3, and the positioning holes 10 are arranged at equal distances on the surface of the plug board 3, providing multiple position options to adapt to different working heights. A collector 11 is fixedly installed on the bottom surface of the support plate 2. The collector 11 can be fixed to the support plate 2 by bolts or welding to ensure the stability during operation and the accurate transmission of signals.

[0027] Embodiment 2

[0028] Please refer to Figure 5, a holding mechanism is provided on the bottom surface of the base 1. The holding mechanism includes a holding handle 13, and the holding handle 13 is fixedly installed on the bottom surface of the base 1. A holding groove 14 is formed on the side surface of the holding handle 13. The design of the holding groove 14 makes it more convenient for the operator to lift the device, and the anti-slip effect is remarkable. In addition, a bottom groove 15 is formed on the bottom surface of the holding handle 13, and a bottom block 16 is slidably connected to the inner wall of the bottom groove 15. The material of the bottom block 16 is ferritic stainless steel, which has good magnetic properties and corrosion resistance and is suitable for use in complex outdoor environments. The counterweight block 18 is of a cylindrical structure. The bottom groove 15 is adapted to the size of the bottom block 16, and both the bottom groove 15 and the bottom block 16 are of a "T" - shaped structure. A magnet 17 is fixedly installed on the inner wall of the bottom groove 15. The magnetic force between the magnet 17 and the bottom block 16 can firmly fix the bottom block 16 and prevent it from shifting during use. A counterweight block 18 is fixedly installed on the bottom surface of the bottom block 16. The counterweight block 18 helps the device to fit more closely to the cable surface by gravity, improving the accuracy of data collection.

[0029] Working principle: The operator can hold the grip 13 to lift the present utility model, then place the cable into the guide wheel 6, and then release the hand. Then, due to the action of gravity, the cable can press against the guide wheel 6 and the collector 11. At this time, the collector 11 can collect the information parameters of the power line, so as to give an early warning of the abnormality of the power line. Moreover, the operator can also adjust the distance between the base 1 and the support plate 2 according to the actual thickness of the cable, so that the present utility model can better adapt to different cables. When adjusting, only need to pull the pull handle 8, and the pull handle 8 can then drive the positioning rod 7 to move until the positioning rod 7 leaves the positioning hole 10. At this time, the limit is released, and then the support plate 2 can be pushed up or down. The support plate 2 can then drive the insertion plate 3 to move in the slot 4. After adjusting to the appropriate position, release the pull handle 8. Then, due to the pulling force of the tension spring 9, the tension spring 9 can pull the pull handle 8 to move, and the pull handle 8 can then drive the positioning rod 7 to move until the positioning rod 7 is inserted into the positioning hole 10. At this time, the position between the support plate 2 and the base 1 can be limited. In the present utility model, the operator can flexibly adjust the distance between the base 1 and the support plate 2 according to the actual thickness of the cable, so that the present utility model can adapt to different diameters or types of cables, especially in the working scenario of dealing with various different specifications of cables. And only need to simply pull the pull handle 8 to adjust the position of the support plate 2, making the operation process intuitive and easy to execute, avoiding complex steps or tools, improving the work efficiency and operation convenience. The design of the positioning rod 7 and the positioning hole 10 allows the position of the support plate 2 to be quickly and accurately locked, ensuring the stability and reliability of the adjustment process. After releasing the pull handle 8, the action of the tension spring 9 can automatically pull the positioning rod 7 back to the locked position. This automatic locking function reduces the operator's workload and improves the work efficiency. When the operator installs the counterweight 18, only need to align the bottom block 16 on the counterweight 18 with the bottom groove 15 and insert it. After the bottom block 16 is inserted into the bottom groove 15, the bottom block 16 can press against the magnet 17. At this time, because the material of the bottom block 16 is ferritic stainless steel, the magnet 17 can attract the bottom block 16 due to the magnetic force. At this time, the bottom block 16 can be fixed in the bottom groove 15. At this time, the counterweight 18 can be installed through the magnetic force and the damping between the bottom block 16 and the bottom groove 15. Through the counterweight 18, the support plate 2 can move downward, so that the collector 11 can fit the cable more closely, thereby ensuring the data collection effect and improving the early warning accuracy. The present utility model fixes the counterweight 18 in the bottom groove 15 by using magnetic force. The operator can quickly and easily install the counterweight 18 without complex mechanical fixing means or tools, simplifying the installation process. The interaction between the ferritic stainless steel bottom block 16 and the magnet 17 not only provides a stable fixing method, but also effectively installs and fixes the counterweight 18 through the combination of magnetic force and damping. The use of the counterweight 18 makes the support plate 2 move downward, so that the collector 11 can fit more closely to the cable surface, thereby reducing the error in the data collection process and improving the accuracy of the data and the reliability of the early warning.

[0030] As described above, it is only the preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
