Description

Technical Field

[0001] This application relates to the field of power transmission line inspection, and in particular to a power transmission line inspection system. Background Technology

[0002] Transmission line inspection refers to the regular inspection and monitoring of transmission lines and their related facilities to ensure their normal operation and safety. Inspection work includes a detailed examination of all components of the transmission line, timely detection of equipment defects and faults, and detailed recording as a basis for line maintenance. Transmission line inspection is a crucial task for ensuring the safe operation of the power system. It is of great significance for standardizing line management, improving line operation levels, and ensuring the safe and reliable operation of the power grid. Through regular inspections, potential faults in power equipment can be detected and eliminated in a timely manner, ensuring the safe operation and reliable supply of the power system. During conventional transmission line inspections, the inspection machine is moved along the transmission line using a sliding frame. A camera is installed at the bottom of the inspection machine to capture images of the inspected line and transmit the video to the operator's computer, facilitating the inspection of equipment on the line.

[0003] Regarding the aforementioned technologies, the inventors believe that when conventional power transmission line inspection equipment moves along the power transmission line, the line is located at a high position with no obstructions, making it prone to strong winds. This causes the inspection equipment to shake, resulting in blurry videos and affecting the inspection results.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0024] Reference Figure 2 A slider 6 is installed at one end of the rotating rod 5. The surface of the slider 6 is slidably connected to the inner wall of the adjusting frame 7. The slider 6 facilitates the movement of the rotating rod 5 within the adjusting frame 7, thereby adjusting the distance between the first sliding frame 3 and the second sliding frame 8. This allows for easy adjustment of the position of the second sliding frame 8 based on the distance between the two lines. A rubber pull rope 9 is installed at one end of the rotating rod 5. One end of the pull rope 9 is connected to the inner wall of the adjusting frame 7. The pull rope 9 is used to pull the adjusting frame 7, thereby controlling the retraction of the adjusting frame 7 when the distance between the two lines decreases. An electric push rod 10 is rotatably connected to the bottom end of the rotating rod 5. A fixed seat 11 is rotatably installed at the bottom end of the electric push rod 10.
