Abstract
This invention discloses a tower structure for a blower, which comprises a column-shaped tower body, wherein a plurality of transverse reinforcement rings are evenly distributed on the tower body; a plurality of vertical reinforcement ribs are also evenly distributed on the tower body; the middle of the column-shaped tower body is hollow; and the reinforcement rings and the reinforcement ribs are arranged on the inner wall of the tower body. The tower structure disclosed by this invention has a benefit effect that because a plurality of the transverse reinforcement rings and a plurality of vertical reinforcement ribs are evenly distributed on the tower body, axial loading capacity and transverse loading capacity of a tower can be enhanced so as to ensure a tower body structure not to be buckled or broken; while intensity same as a tower with a large diameter and a large wall thickness is obtained, the diameter and the wall thickness of the tower of a large blower are reduced; construction cost and cost are reduced; and transportation and hoisting are processed conveniently.
Description
[technical field]
The present invention relates to be used for the tower barrel structure of blower fan.
[background technique]
At present; The tower tube of most of wind-driven generator adopts circular steel tower tube, along with the blower fan generated output constantly increase (＞5MW), all corresponding increase of blower fan weight and length of blade; The tower tube diameter and the thickness that support blower fan also constantly increase; For domestic present present situation, the making of major diameter tower tube, transportation and installation are very difficult.Many times, in the face of high-power wind-driven generator, the intensity of tower tube, rigidity are satisfied, but transportation and installation but bother very much, even can't transport and install.
[summary of the invention]
The objective of the invention is to overcome the deficiency of existing technology; Provide a kind of cylindrical tower tube complete buckling that reduced to destroy and local buckling failure; And diameter and wall thickness, convenient transportation and the tower barrel structure of installing that is used for blower fan of tower tube in the same intensity of tower tube that reaches with major diameter, big wall thickness, have been reduced.
The objective of the invention is to realize like this:
The tower barrel structure that is used for blower fan is characterized in that it includes the tower tube body of cylindricality, is evenly equipped with many horizontal stiffening rings on the described tower tube body; Also be evenly equipped with many vertical stiffening ribs on the described tower tube body.
The aforesaid tower barrel structure that is used for blower fan is characterized in that the middle hollow out of the tower tube body of described cylindricality, and stiffening ring and stiffening rib are arranged on the inwall of tower tube body.
The aforesaid tower barrel structure that is used for blower fan is characterized in that the cross section of described horizontal stiffening ring is a T shape.
The aforesaid tower barrel structure that is used for blower fan is characterized in that the cross section of described horizontal stiffening ring is
shape.
The aforesaid tower barrel structure that is used for blower fan is characterized in that the cross section of described horizontal stiffening ring is a rectangular.
The aforesaid tower barrel structure that is used for blower fan, the cross section that it is characterized in that described horizontal stiffening ring is for spherical.
The aforesaid tower barrel structure that is used for blower fan is characterized in that the cross section of described vertical stiffening rib is a T shape.
The aforesaid tower barrel structure that is used for blower fan is characterized in that the cross section of described vertical stiffening rib is
shape.
The aforesaid tower barrel structure that is used for blower fan is characterized in that the cross section of described vertical stiffening rib is a rectangular.
The aforesaid tower barrel structure that is used for blower fan, the cross section that it is characterized in that described vertical stiffening rib is for spherical.
The invention has the beneficial effects as follows owing on tower tube body, be evenly equipped with many horizontal stiffening rings, also be evenly equipped with many vertical stiffening ribs, make axial, the lateral load ability of tower tube be enhanced, guarantee that tube structure can buckling failure.In the same intensity of tower tube that reaches with major diameter, big wall thickness, reduce large fan tower tube diameter and wall thickness, reduce cost and cost, convenient transportation and lifting.
