The tops of the multiple lightning protection components 2 are all connected with lightning protection wires 3, and the lightning protection wires 3 are connected to the first conductor 4. The first conductor 4 is connected to one end of the lightning arrester 5, and the other end of the lightning arrester 5 is connected to the grounding down conductor 6. The grounding down conductor 6 is connected to the ground through the grounding shoe 7. The conductive carbon plate 8 of the grounding shoe 7 is set on the rail 10 below the portal crane 9. A current ring 31 is installed on the grounding down conductor 6 for detecting the current on the grounding down conductor 6.
