Magnets corresponding to the magnetic absorption fixing blocks 123 are installed on the inner wall of the module bracket 101. During installation, each component and terminal are inserted into the positioning groove 102. After being pushed to the bottom, the magnetic absorption fixing block 123 is adsorbed by the magnet at the bottom of the positioning groove 102 to pre-fix the component to the module bracket 101. Multiple quick-release bolts 122 for fixing to the module bracket 101 are provided at one end of the laser ranging component 11, the video monitoring component 12, the infrared temperature measurement component 13, the data processing terminal 14, the vibration monitoring component 15, the control terminal 16, the micro-meteorological monitoring component 17, the communication component 18, and the power supply component 19. After pre-fixation, tightening the quick-release bolts 122 can fixedly install the monitoring module inside the box body 1.

[0039] Among them, the moving component 2 is installed on the top of the box body 1. The moving component 2 is used to drive the box body 1 to move along the overhead line to continuously monitor the transmission line.

When the device encounters obstacles such as wire splicing sleeves, strain clamps and insulator strings, the two fixing plates 26 on one side can be driven by the telescopic motor 252 to move away for obstacle avoidance. The two fixing plates 26 on the other side keep clamping the wire to make the moving block 24 relatively stationary with the wire. Then the driving unit 241 drives the moving slide rail 21 to move, so that one fixing plate 26 straddles the obstacle. After the fixing plate 26 passes through the obstacle, they approach each other again to clamp the wire. Then the same operation is taken to make the other fixing plate 26 straddle the obstacle. The device can move a long distance on the wire, can monitor a larger range, reduce the deployment quantity of monitoring equipment and lower the maintenance cost.

The data processing terminal 14 preprocesses the received monitoring data and combines analysis algorithms to fuse and analyze the multi-module monitoring data to generate a risk assessment report. For example, by fusing and analyzing the monitoring data of the vibration monitoring component 15 and the micro-meteorological monitoring component 17, calculating the theoretical ice coating thickness according to the current meteorological data and the conductor vibration change data, and predicting the future ice coating growth trend in combination with historical data to issue an early warning in advance.
