Description
Technical field
The present invention relates to a kind of offshore wind power equipment, particularly a kind of offshore wind farm jacket frame foundation structure.
Background technology
Along with offshore wind turbine installed capacity increases year by year, offshore wind power foundation presents variation, the high dynamic stress district of the as easy as rolling off a log formation of offshore wind power foundation structure, and fatigue damage is comparatively large, and a lot of basic transition section planform is complicated, production and processing difficulty is large.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides that a kind of structure is simple, stress distribution rationally, lighter in weight, high dynamic stress district is few, cost is low offshore wind farm jacket frame foundation structure.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of offshore wind farm jacket frame foundation structure, comprise three conduits that cross section is triangularly arranged, the top of described conduit is connected with leg-of-mutton support platform, the center of support platform is provided with main cylinder, described support platform comprises the upper sealing plate welded with described main cylinder and conduit, lower shrouding and up and down both sides are welded on described upper sealing plate respectively, curb girder on lower shrouding, auxiliary beam and girder, described girder is 120 degree of distributions, two ends are welded with described main cylinder and conduit respectively, described curb girder is arranged along the sideline of described support platform, two ends are welded with described conduit upper end respectively, described auxiliary beam is perpendicular to curb girder, two ends respectively with described main cylinder and side beam welding.
Diagonal brace is provided with between described conduit.
The top of described main cylinder is provided with basic flange.
The invention has the beneficial effects as follows: offshore wind farm jacket frame foundation structure of the present invention has that structure is simple, stress distribution rationally, few, the low cost and other advantages in lighter in weight, high dynamic stress district.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
