Wind turbine generator lattice type tower with enhanced recoverable and energy dissipation capacities

Abstract

The invention discloses a wind turbine generator lattice type tower with enhanced recoverable and energy dissipation capacities. The tower comprises a tower main rod, a tower transverse supporting rod, a tower inclined supporting rod, a connecting end plate and at least two structural units; and each structural unit comprises two pieces of T-shaped steel, which are parallel to each other and can vertically move mutually, each piece of T-shaped steel is welded to the end of the tower transverse supporting rod, two friction outer plates which are in sliding friction with web plates of the two pieces of T-shaped steel are arranged on the two sides of the web plates in the same direction of the two pieces of T-shaped steel, and the two friction outer plates are connected with the T-shaped steel through elastic return assemblies. According to the tower, an energy dissipation effect is achieved through friction sliding between the webs of the T-shaped steel and the friction outer plates, a self-return function is achieved through the elastic return assemblies, an energy dissipation function and a recoverable function of the whole tower are enhanced through a mutual transverse dislocation mechanism of the T-shaped steel and the friction inner plates, and the anti-seismic requirements of different levels can be met.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a lattice structure tower frame of a wind power unit with enhanced recoverable energy consumption capacity. Background technique [0002] Environmental pollution and resource shortage have always been global problems that need to be solved urgently. As a clean energy source, wind power has received more and more attention. As the supporting structure of wind turbines, the tower's bearing capacity and mechanical performance directly affect The safety and stability of the unit during operation. Most cities in my country are located in earthquake zones, and the seismic performance of wind turbine towers has been severely tested. Traditional lattice towers mainly consume seismic energy through the plastic deformation of rods. On the one hand, this energy consumption method is not easy to be accurate. It is difficult to assess the damage of the structure by locating the damage location;...
