[0002] Offshore wind power is a device that has wind turbines fixed on the seabed, which use the wind on the sea surface to operate the wind turbines and generate electricity. Due to the abundant wind energy on the sea surface, offshore wind power is more common in some locations far away from residents and without breeding conditions.

The connection between the lightning protection blocks is more stable through the connection of the clamping structure and the installation blind hole, thereby improving the overall The load-bearing capacity of the structure, but the traditional offshore wind power lightning protection device is fixed to the wind power device by fixing screws.
