The outer end of the arc rod 11 is provided with an arc inner groove 12.

[0031] The inner end of the positioning arc plate 3 is provided with a sensing element, which facilitates the sensing of the circuit condition while the monitor 1 moves in contact with the power transmission line. The data is transmitted back to the inside of the pole through the data transmission line from the linkage harness 15, and the system transmits the data to the detection platform.

[0032] The outer end of the linkage harness 15 is connected with a rope collector, which facilitates the synchronous stretching and contracting of the linkage harness 15 when the monitor 1 moves along the line. The linkage harness 15 is connected to the pole.

[0033] The monitor 1, through the unique design of its positioning arc plate 3, linkage rod 7 and other components, can maintain good contact with the line when the power transmission line is displaced or changed, thereby ensuring the accuracy and stability of the monitoring.

This design not only ensures the safety and real-time of information transmission, but also simplifies the complex wiring of traditional monitoring system, reduces the maintenance cost;

[0035] The introduction of the rope collector enables the monitor 1 to move freely along the power transmission line, while the linkage harness 15 automatically stretches and contracts, avoiding the problem of data transmission interruption caused by the change of line length. This greatly enhances the flexibility and adaptability of the entire system;

[0037] The light reflection beam powered by the solar cell panel plays a role of position tracking and warning at night;

[0038] The solar cell panel on the light reflection strip 14 provides power for the light reflection beam, so that the light reflection beam can also play a role at night. This not only saves energy and reduces the dependence on the power grid, but also provides important visual identification at night and increases the safety protection of the operating personnel.
