Description
Technical field
The invention belongs to wind power generation stepped technical field, and in particular to a kind of with the pre- of the direct blower fan annular box beam of tower top
Stress polygon wind tower.
Background technology
With the appearance of the wind power generation tower structure such as framework type wind tower, the design of lattice wind tower also brings new asking
Topic：One is that fan blade sweeps tower problem, and this requires Trellis tower mast top to the long sufficiently small apart from inner edge of blade tip, with
Adapt to the apron space requirement of blade.Traditional method uses quadrangle tower body, but this quadrangle tower body is smaller in the length of side
In the case of, king-post stress is huge, and steel using amount is high；Two is that tower body to be facilitated is connected with cabin, fan engine room with it is wind power generation stepped
Tower body typically using the connection of large-diameter circular flange, traditional way be in one section of circular tower of Trellis tower mast top design,
Atop a tower design flange is connected with cabin.But connection tower is complicated with the changeover portion of tower body, materials are more, and power transmission is not straight
Connect.
The content of the invention
For the above-mentioned technical problem for overcoming prior art to exist, it is an object of the present invention to provide one kind is carried
The prestressing force polygon wind tower of the direct blower fan annular box beam of tower top, improves stock utilization, facilitates tower body with engine room facilities
Connection.
A kind of prestressing force polygon wind tower with the direct blower fan annular box beam of tower top that the present invention is provided, it includes steel knot
Structure Trellis tower mast, fan engine room adpting flange and annular box beam, the annular box beam are connected to steel construction Trellis tower mast top
Portion, the steel construction Trellis tower mast includes king-post, cross bar, brace, and prestress wire, the ring are provided with inside the king-post
Shape box beam includes annular box beam top flange, annular box girder web, donought lower flange of girder edge, ring beam bottom flange, inside the king-post
Prestress wire is anchored on annular box beam top flange, and the fan engine room adpting flange is connected with annular box beam.
The steel construction Trellis tower mast is octagon tower body or regular hexagon tower body, and the king-post is steel pipe, described
Cross bar, brace can be using shaped steel or the double C-type section steels of bending and molding, and the fan engine room adpting flange passes through annular box beam
Bolt A on the inside of top flange is connected with annular box beam, and the king-post top is provided with king-post top flange, the donought lower flange of girder edge
Ring beam bottom flange is provided with, king-post top flange is connected with ring beam bottom flange by bolt B.
A kind of prestressing force polygon wind tower with the direct blower fan annular box beam of tower top that the present invention is provided, its advantage
It is in the case that steel construction Trellis tower mast top hem width is limited, using octagon or regular hexagon tower body, to improve material
The utilization rate of material；Fan engine room is connected by fan engine room adpting flange with the annular box beam at the top of steel construction Trellis tower mast,
Instead of traditional tower segments and changeover portion, power transmission directly, saves material.
