Abstract

The invention discloses a sea wind power guiding pipe frame foundation structure which comprises three guiding pipes, wherein the cross sections of the three guiding pipes are triangular, a triangular supporting platform is connected onto the upper parts of the guiding pipes, the supporting platform comprises an upper sealing board, a lower sealing board, a side beam, an auxiliary beam and a main beam, the upper sealing board and the lower sealing board are welded with a main cylinder body and the guiding pipes, the upper sides and the lower sides of the side beam, the auxiliary beam and the main beam are respectively welded on the upper sealing board and the lower sealing board, the main beam is distributed in 120 degrees, the two ends of the main beam are welded with the main cylinder body and the guiding pipes, the side beam is distributed along the edge line of the supporting platform, the two ends of the side beam are respectively welded with the upper ends of the guiding pipes, the auxiliary beam is perpendicular to the side beam, and the two ends of the auxiliary beam are respectively welded with the main cylinder body and the side beam. The sea wind power guiding pipe frame foundation structure has the advantages of being simple in structure, reasonable in stress distribution, light in weight, few in high dynamic stress areas, low in cost and the like.

Description

technical field [0001] The invention relates to an offshore wind power equipment, in particular to a basic structure of an offshore wind power jacket. Background technique [0002] As the installed capacity of offshore wind turbines increases year by year, offshore wind power foundations are diversified. Offshore wind power foundation structures are prone to form high dynamic stress areas, with large fatigue damage, and many foundation transition sections have complex structures and difficult production and processing. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an offshore wind power jacket foundation structure with simple structure, reasonable stress distribution, light weight, few high dynamic stress areas and low cost. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] An offshore wind power jacket foundation structure, comprising th...
