Description

Technical Field

[0001] This utility model relates to the field of inspection device technology, and more specifically, to a three-dimensional inspection device for power transmission lines. Background Technology

[0002] With the development of the power industry and the advancement of smart grid construction, the safe operation and efficient maintenance of transmission lines have become one of the core tasks of power companies. Traditional transmission line inspection methods mainly rely on manual inspection and drone inspection: manual inspection suffers from problems such as long inspection cycles, large workload, low efficiency, and safety hazards; while drone inspection, although improving inspection efficiency to some extent, is limited by factors such as flight time, weather conditions, and operational complexity, making it difficult to achieve continuous and comprehensive monitoring of transmission lines and their surrounding environment.

[0003] In recent years, with the continuous advancement of video surveillance technology and the improvement of its intelligence level, it has gradually become possible to conduct three-dimensional inspections of power transmission lines using video surveillance technology. However, traditional video surveillance devices are often limited to monitoring from a fixed angle, making it difficult to achieve comprehensive coverage of the power transmission lines and their surrounding environment. This may result in some problems being missed due to angle limitations and going undetected in a timely manner. Furthermore, due to the limited inspection angle, multiple repeated inspections or the addition of inspection points are often required to ensure coverage of all areas, which not only increases inspection costs but also wastes human resources and time. To address these problems, this device was invented. Utility Model Content

The connecting plate 21 has multiple mounting ports and an L-shaped cross-section. The connecting plate 21 has a first groove 22 and a limiting groove 23. A rotating disk 24 is disposed in the first groove 22 and a limiting ring 25 is fixedly disposed on the rotating disk 24. The limiting ring 25 is slidably connected in the limiting groove 23.

[0027] A support rod 26 is fixedly installed on the upper end face of the rotating disk 24. The support rod 26 is connected to the video inspection device 1 through a rotating connecting seat. A connecting cylinder 27 is provided on one side of the support rod 26. A rotating wheel 28 is rotatably connected to the lower end face of the connecting cylinder 27. A second groove 29 is provided on the connecting plate 21. The rotating wheel 28 is slidably installed in the second groove 29.

[0028] A rod 210 is inserted into the upper end face of the connecting cylinder 27. The top end of the rod 210 is slidably connected to the video inspector 1 through a rotating connecting seat. A connecting block 212 is rotatably provided at the bottom end of the rod 210. A protrusion 215 is fixedly provided on the connecting block 212. A telescopic rod 211 is rotatably provided at the bottom end of the inner side of the connecting cylinder 27. The top end of the telescopic rod 211 is connected to the connecting block 212.

[0029] Multiple slots 213 are provided on the inner wall of the connecting cylinder 27. The protrusions 215 on the connecting block 212 are slidably connected in the slots 213 on the inner wall of the connecting cylinder 27. The multiple slots 213 are arranged vertically. A connecting groove 214 is provided between two adjacent slots 213. A drive motor 216 is fixedly provided on the lower end face of the connecting plate 21. The output end of the drive motor 216 is connected to the rotating disk 24.

[0030] The two ends of the connecting groove 214 are connected to two adjacent slots 213. The diameter of the slot 213 is equal to the diameter of the connecting groove 214. The diameter of the protrusion 215 is adapted to the diameter of the slot 213 and the connecting groove 214. A guide groove is provided on the lower end face of the video inspector 1. A guide block is fixedly provided on the rotating connecting seat at the top of the plug rod 210. The guide block of the rotating connecting seat at the top of the plug rod 210 is slidably connected in the guide groove on the lower end face of the video inspector 1.

[0031] By setting up the video inspection device 1, monitoring images of the transmission lines supported by the towers and the transmission lines near the towers can be aggregated to generate a panoramic view of the transmission lines, restoring the real-time situation of the transmission lines. The aggregated panoramic view can then be observed to monitor for potential problems. This reduces the labor intensity and working conditions of traditional transmission line inspections and improves their efficiency. Simultaneously, it can collect meteorological data about the environment around the towers, helping maintenance personnel to quickly locate faults and assist in developing repair plans. The connecting component 2 not only connects the video inspection device 1 to the towers supporting the transmission lines but also allows for adjustment of the horizontal and vertical angles of the video inspection device 1, thus enabling comprehensive monitoring of the transmission lines and their surrounding environment. The comprehensive coverage of the environment makes this all-round inspection method helpful in discovering problems that may be missed due to angle limitations, and avoids the waste of resources caused by repeated inspections or missed areas. It helps to shorten the inspection cycle and improve inspection efficiency. At the same time, in the process of adjusting the inspection angle, the video inspector 1 can get closer to the transmission line, thereby capturing clearer and more detailed image information, which helps maintenance personnel to more accurately judge the operating status of the transmission line and discover potential safety hazards in time. In addition, in the complex and ever-changing natural environment, the transmission line may be affected by various external factors, such as strong winds and heavy rain. Through the design of the connecting component 2, the video inspector 1 can flexibly adjust the inspection angle while ensuring safety to cope with different weather conditions and inspection needs.

[0032] See attached document Figures 1-5 A connecting frame 4 is fixedly connected to the lower end face of the connecting plate 21. A solar panel 3 is fixedly installed on the connecting frame 4. A protective shell 5 is fixedly connected to the upper end face of the video inspection device 1. Two sliding grooves 6 are opened on the inner side wall of the connecting cylinder 27. Two sliders 7 are fixedly installed on the insertion rod 210. The two sliders 7 slide in the two sliding grooves 6 respectively.

[0033] The solar panel 3 can convert solar energy into electrical energy to power the video inspection device 1. The connecting frame 4 is used to connect the connecting plate 21 to the solar panel 3. The sliding groove 6 and the slider 7 can improve the stability of the insertion rod 210 moving longitudinally within the connecting cylinder 27.

[0034] In use, the video inspection device 1 is first fixedly connected to the tower supporting the power transmission line via the connecting plate 21. The video inspection device 1 and drive motor 216 are started periodically (e.g., every half hour). The start of the video inspection device 1 monitors the power transmission line near the tower. The start of the drive motor 216 causes the rotating disk 24 to rotate. The rotating disk 24, via the support rod 26, causes the inspection angle of the video inspection device 1 to rotate in the horizontal plane. During rotation, the video inspection device 1 drives the rotating wheel 28 to rotate within the second groove 29 via the connecting cylinder 27. The rotation of the rotating wheel 28 causes the telescopic rod 211 within the connecting cylinder 27 to rotate. The telescopic rod 211 causes the connecting block 212 and the protrusion 215 on the connecting block 212 to rotate. When the protrusion 215 on the connecting block 212 rotates from the slot 213 into the connecting groove 214... The insertion rod 210 pushes the video inspector 1 to rotate in the vertical plane. When the protrusion 215 rotates back into the slot 213, the inspection angle of the video inspector 1 continues to rotate in the horizontal plane. This process is repeated until the protrusion 215 reaches the end of its stroke. Then, the video inspector 1 and the drive motor 216 are turned off. During the rotation, the video inspector 1 collects monitoring images of the transmission lines supported by the tower and the transmission lines near the tower to generate a panoramic view of the transmission lines, restoring the real-time situation of the transmission lines. The panoramic view of the transmission lines is observed to monitor whether there are any problems with the transmission lines. When it is necessary to monitor the transmission lines supported by the tower and the transmission lines near the tower again, the drive motor 216 is started in reverse phase according to the above method until the protrusion 215 on the connecting block 212 moves to the beginning of its stroke.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
