AI Technical Summary

Technical Problem

Existing truss-type wind turbine towers struggle to meet load-bearing capacity requirements when the rotor diameter exceeds 220m, especially due to significant fatigue effects under wind loads and mechanical operation.

Method used

Increase the number of tower columns to six or eight, and set them as symmetrical hexagons or octagons, with diagonal bracing and cross bracing, and add horizontal bracing. Set foundation anchoring devices at the bottom of the tower columns, and the transition section is a segmented structure to adapt to the hexagonal or octagonal cross section of the tower body, thereby increasing the number of force transmission points.

Benefits of technology

By distributing the stress on the tower columns and diagonal braces, the size of the tower is reduced, the bending and torsional resistance of the tower body is improved, the load-bearing requirements of the large impeller are met, and the tower is easy to transport and construct quickly.

Abstract

The truss type wind power tower structure comprises a tower body, a tower drum and a transition section which is located between the tower body and the tower drum and plays a role in transition connection. Wherein the tower body comprises a plurality of tower columns and inclined rods connected between every two adjacent tower columns; the number of the tower columns is six or eight, the six tower columns are arranged in a symmetrical hexagon shape, and the eight tower columns are arranged in a symmetrical octagon shape. And the transition section is matched with the tower body and has a hexagonal or octagonal section. According to the tower structure, the number of the tower columns is increased from traditional four to six or eight, the stress of the tower columns is dispersed, the specifications of the tower columns are reduced, and the bending resistance and structural rationality of the tower body can be improved; meanwhile, the tower surface is increased, the stress of the inclined rods is dispersed, the specification of the inclined rods is reduced, and the torsion resistance and the structural rationality of the truss are improved, so that the framework type wind power tower structure can meet the bearing capacity requirement that the diameter of an impeller exceeds 220m.
