Abstract
The utility model discloses a three-pile guide pipe frame foundation structure of an offshore wind turbine. The three-pile guide pipe frame foundation structure comprises an upper portion rigid connection part and a working platform. The working platform is supported by a three-pile guide pipe frame which is composed of three foundation piles and three steel piles, wherein the three foundation piles are fixed on a seabed, and the three steel piles are fixedly connected with the three foundation piles in a one-to-one corresponding mode. The cross sections of the three steel piles are in the shape of a regular triangle, and a cone-shaped body is defined by the three steel piles, wherein the cross section area of the cone-shaped body has a large lower end and a small upper end and is gradually decreased from bottom to top. The steel piles are welded and strengthened through X-shaped steel connection parts. According to the three-pile guide pipe frame foundation structure of the offshore wind turbine, on the premise that a draught fan stably operates, compared with a current four-pile guide pipe frame foundation which is widely used, one pile leg is eliminated in the three-pile guide pipe frame foundation structure, and the three-pile guide pipe frame foundation structure has the advantages of being simpler in structure, lower in weight, more convenient to manufacture, transport and install, lower in cost and the like.

Technical field
The utility model relates to a kind of offshore wind generating jacket frame foundation structure, particularly a kind of offshore wind generating three pile leader frame foundation structures, and this foundation structure is adapted to the Oversea wind power generation industry in depth of water 5-55m marine site.
Background technology
Up to the present, China in the Inner Mongol, Xinjiang, Gansu, northeast and the coastal region in east China built up large quantities of land wind energy turbine set.But along with the fast development of wind-powered electricity generation industry, land wind-resources has been used totally, the imperative ，Qie of offshore wind farm China has very long coastline, and abundant offshore wind energy resource, and offshore wind farm will obtain tremendous development.
Utility model content
The utility model provides a kind of marine three pile leader frame foundation structures, meeting under the prerequisite of blower fan stable operation, this three pile leaders frame foundation structure has reduced by a pile leg compared to four pile leader frame bases of current extensive use, there is structure simpler, weight is lighter, and make, transport, install more convenient, the advantage such as cost is lower.
The purpose of this utility model is achieved through the following technical solutions:
A kind of offshore wind generating three pile leader frame foundation structures, comprise top rigid connector, working platform, working platform is supported by three pile leader framves, three pile leader framves by be fixed on three pile foundation stakes on sea bed and with three pile foundation stakes one by one corresponding three piling bars that are fixedly linked form, the steel connector welding with " X " shape between each piling bar is strengthened.
Further improve: three piling bar cross sections are equilateral triangle setting, it is little that three piling bars surround a large upper end, cross-sectional area lower end, and the bullet reducing gradually from down to up.
Further improve: piling bar connects by flange or filling concrete is fastened on foundation pile.
Further improve: working platform between three pile leader framves and top rigid connector, a plurality of variable cross-section pipe lower ends and piling bar welded top, weld with rigid connector variable cross-section pipe upper end, and reinforcement processing is done in part.
The utility model has following advantage and effect with respect to prior art: the utility model is according to China coastal seas marine site condition, a kind of offshore wind generating three pile leader frame bases that are adapted to depth of water 5-55m marine site scope have been proposed, meeting under the prerequisite of blower fan stable operation, a pile leg has been reduced by compared to more than four or four jacket basis of current extensive use in this basis, reduce blower foundation steel using amount, thereby saved cost; Have structure simpler, weight is lighter, and make, transport, install more convenient, the advantage such as cost is lower.
