Abstract

The invention discloses an offshore wind power generating set foundation structure. The offshore wind power generating set foundation structure comprises a plurality of hollow steel pipe piles and an independent upper inclined strut structure. The upper inclined strut structure is composed of a foundation main cylinder body, a plurality of inclined struts and a plurality of insertion section steel piles. The insertion section steel piles are inserted in the hollow steel pipe piles respectively. The offshore wind power generating set foundation structure is relatively simple in structure and easy to manufacture, and overcomes the shortcoming that a complex foundation structure is high in manufacturing difficulty. Basic components can be transported and installed separately, installation difficulty is low, and foundation stability is good.

Description

A kind of offshore wind generating group fondational structure
[technical field]
The present invention relates to a kind of offshore wind generating group fondational structure, belong to wind power generation field.
[background technique]
Along with the development of offshore wind farm, continually developing of the marine wind field of the fast development of high-power blower technology and deep water especially, steel wind-powered electricity generation fondational structure is adopted by increasing marine wind electric field because its installation and transportation are convenient, and global stability is better.But there is following shortcoming in now a lot of offshore wind farm bases: offshore wind farm fondational structure more complicated, manufacture difficulty height; The offshore wind farm basis is the integrative-structure of welding, and the transportation installation difficulty is big.
[summary of the invention]
The objective of the invention is to overcome the prior art deficiency, a kind of novel offshore wind farm unit fondational structure is provided, its structure is simple relatively, be easy to make, and overcomes complicated fondational structure manufacture difficulty height; And basic components can separately transport and install, and installation difficulty is low, and stability of foundation is better.
The present invention has adopted following technical proposals:
A kind of offshore wind generating group fondational structure, comprise a plurality of Hollow Steel pile tubes, top diagonal brace structure independently, top diagonal brace structure is made up of basic main cylinder, a plurality of diagonal brace and a plurality of insertion section piling bar, and each inserts the section piling bar and is inserted into respectively in each Hollow Steel pile tube.
