Abstract

The invention discloses a prestressed polygon wind tower with a direct fan annular box girder at the tower top. The prestressed polygon wind tower comprises a steel structure lattice tower body, a fan cabin connection flange and an annular box girder, wherein the annular box girder is connected to the top of the steel structure lattice tower body; the steel structure lattice tower body comprises a tower column, a cross rod and an oblique rod; a prestress wire is arranged in the tower column; the annular box girder comprises an annular box girder top flange, an annular box girder web, an annular box girder bottom flange and an annular girder bottom flange; the prestress wire in the tower column is anchored on the annular box girder top flange; and the fan cabin connection flange is connected with the annular box girder. Traditional tower drum segment and transition segment are replaced, force transferring is direct and the material is saved.

Description

technical field [0001] The invention belongs to the technical field of wind power generation towers, in particular to a prestressed polygonal wind tower with an annular box girder directly on the top of the tower. Background technique [0002] With the emergence of new wind power tower structures such as framed wind towers, the design of latticed wind towers also brings new problems: one is the problem of wind turbine blade sweeping, which requires the distance from the top of the latticed tower body to the blade tip The distance from the inner edge is small enough to meet the running space requirement of the blade. The traditional method uses a quadrilateral tower body, but when the side length of this quadrilateral tower body is relatively small, the tower column bears a huge force and the amount of steel used is high; the second is to facilitate the connection between the tower body and the engine room, and the wind turbine engine room and the wind power generation towe...
