Preferably, support piece includes fixed plate and buckle, the buckle is that both ends establish screwed "U" font structure, lightning-arrest net is arranged in the buckle and passes through the nut with the fixed plate and be connected, the fixed plate bottom pass through bolt two with cabin cover fixed connection, lightning-arrest net and support piece's surface brush has a silver powder finish paint.

Preferably, the clamp is fixed on the side surface of the top of the support through a third bolt, the clamp is in a shape like a Chinese character 'ji', an opening of the clamp faces away from the support, a threaded hole is formed in one side of the clamp, a threaded rod penetrates through the threaded hole and is connected with an insulating clamping plate, and insulating lining pieces are arranged on the other two sides of the clamp respectively.

Preferably, the bottom of the lightning rod is connected with the metal sleeve sleeved on the lightning protection net through a lead.

The utility model has the advantages of as follows:

the utility model discloses a lightning rod is fixed to anchor clamps, can be suitable to the height that upwards stretches out of lightning rod when needs, and it is very convenient to adjust. The lightning rod can be used for quickly introducing the current generated by the lightning stroke into the ground, so that the anemoscope and the wind vane are prevented from being hit. The lightning protection net covers all parts of the surface of the cabin cover, so that the possibility that the cabin cover and equipment inside the cabin cover are struck by lightning is effectively avoided. The support piece can support the lightning protection net, and is simple in structure and convenient to install.
