[0006] Preferably, the lower fan-shaped positioning part is provided with a positioning groove, and the positioning grooves form an annular structure groove, and a reinforcing ring is embedded in the annular structure groove.

[0007] Preferably, a plurality of pins are arranged in a circular array on the reinforcing ring, and the pins pass through the middle part corresponding to the positioning grooves.

[0008] Preferably, one end of the reinforcing plate is arranged in contact with the side wall of the wind power single pile.

[0009] Preferably, the reinforcing plate is of right-angled triangle structure.

[0010] Compared with the prior art, the utility model has the advantages that: the utility model adopts a conical protective cover of assembled structure, which ensures the anti-impact performance of the whole conical protective cover by replacing the damaged cover body unit, avoids the problem of local damage and overall replacement of the protective cover of integral structure, and increases the investment cost.
