Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with specific embodiments.

[0018] Please refer to figure 1 , figure 1 It is a schematic cross-sectional view of the steel-composite wind turbine tower of the present invention. Such as figure 1 As shown, this

[0019] The steel-composite material fan tower provided by the invention includes a steel inner tube 1 formed by connecting a plurality of conical steel tube segments, and an outer composite material tube formed by a plurality of composite material tube segments. Both tapered steel tube segments and composite tube segments can be factory fabricated.

[0020] The steel inner tube of the present invention is formed by connecting two curved steel sheets through stiffeners 3 , and the two stiffeners 3 are bolted together with high-strength bolts passing through the bolt holes 4 , so as to finally form the steel inner tube 1 .

[0021] The outer composite material cylinder 2 of the present in...

Abstract

The invention discloses a steel-composite material wind-driven generator tower cylinder, which comprises an internal steel pipe and an external composite material pipe, a plurality of conical steel pipe sections are connected to form the internal steel pipe, and the external composite material pipe comprises a plurality of glass fiber composite material pipe sections; corrosion-resistant E-glass fiber cloth is stuck on the surface of each internal steel pipe, so that the steel-composite material combination section is formed; the steel-composite material combination section is circumferentially divided into two pieces; longitudinal reinforcing ribs are arranged along the longitudinal direction of each piece; each two pieces of steel-composite material combination sections are connected together by adopting high-strength bolts, so that a steel-composite material tower cylinder section is formed in the end; and each two steel-composite material tower cylinder sections are connected together through flanges, so that the steel-composite material tower cylinder for on-site installation is formed. Compared with conventional steel wind-driven generator tower cylinders, the steel-composite material wind-driven generator tower cylinder can effectively resist the hit of wind-blown sand and stormy waves, fatigue and corrosion, so that the life of the tower cylinder can be guaranteed.

Description

technical field [0001] The invention relates to a steel-composite material wind turbine tower, which is a supporting structure for wind power generation in offshore and offshore large-scale wind farms, and belongs to the technical field of wind power generation. Background technique [0002] At present, the main form of the support structure for wind power generation is the cone-shaped steel pipe tower, which is generally composed of several sections of 20-30m towers connected by flanges, and the diameter of the towers gradually decreases from bottom to top. However, with the large-scale development of wind turbines, the height of the tower has increased, exceeding the general height limit of 4.5m for expressways in my country. At the same time, wind power is gradually developing from land to offshore and offshore, and traditional steel towers will face serious corrosion problems. A series of problems in these anti-corrosion, processing, transportation and installation have...
