[0027] When connecting the lightning protection grounding wire in the signal room, the staff first connects the grounding wire in the signal room to the second terminal 7 on one side of the movable plate 2, and then connects the two ends of the spiral connecting wire 8 to the two first terminals 6 respectively. Finally, the grounding plate 1 is fixed to the upper end of the ground by bolts. The grounding wire in the signal room is connected to the ground through the movable plate 2, the spiral connecting wire 8 and the grounding plate 1, so as to achieve the grounding purpose of the signal room grounding wire. Then, the positive and negative poles of the grounding resistance tester 9 are respectively connected to the grounding plate 1 and the terminal 13 on the side wall of the movable plate 2. The grounding resistance is monitored in real time by the grounding resistance tester 9, and the two springs 5 ​​mounted on both sides of the lower end of the connecting frame 3 are used to adapt to the slight displacement of the grounding plate 1 caused by temperature changes or mechanical stress. Combined with the flexible connection characteristics of the spiral connecting wire 8, it is ensured that the electrical connection between the grounding plate 1 and the movable plate 2 is always stable, which significantly improves the accuracy of long-term monitoring.
