Abstract
The utility model discloses a foundation structure of an offshore wind-power pipe frame. The foundation structure comprises three pipes arranged in a triangle shape. The upper portions of the pipes are connected with a triangular support platform, the support platform comprises an upper seal plate, a lower seal plate, side beams, auxiliary beams and main beams, wherein the upper seal plate and the lower seal plate are welded with a main barrel and the pipes, the upper sides and the lower sides of the side beams, the auxiliary beams and the main beams are welded on the upper seal plate and the lower seal plate, the main beams are distributed by 120 degrees, two ends of the main beams are welded with the main barrel and the pipes, the side beams are distributed along sides of the support platform, two ends of the side beams are welded with the upper ends of the pipes, the auxiliary beams are perpendicular to the side beams, and two ends of the auxiliary beams are respectively welded with the main barrel and the side beams. The foundation structure of the offshore wind-power pipe frame has the advantages of simplicity, reasonable stress distribution, light weight, few high dynamic-stress areas, low cost and the like.
Description
Technical field
The utility model relates to a kind of offshore wind power equipment, particularly a kind of offshore wind farm jacket frame foundation structure.
