Wind power tower with long and short legs

Abstract

The invention discloses a wind power tower with long and short legs. The wind power tower comprises three or more supporting legs, wherein the supporting legs are different in length and arranged at the bottom of the tower. The wind power tower with the long and short legs is composed of a tower body and the tower legs, wherein the tower body is further divided into an upper part and a lower part, the upper part is of a conical or latticed structure, and the lower part is of a latticed or conical structure. The wind power tower with the long and short legs has the advantages of being convenient to machine, transport and assemble and the like. Because the structure of the long and short legs is adopted for the tower, when the wind power tower is applied to gradient terrains in mountainous areas, earth rock excavation can be reduced, the construction period is greatly shortened, and meanwhile water and soil loss and damage to the biological environment are effectively reduced. Besides, the foundation manufacturing cost and the weight of the tower can be remarkably reduced due to the structure of the long and short legs, and thus the wind power tower with the long and short legs has significant social benefits and economic benefits.

Description

technical field [0001] The invention relates to a wind power tower, in particular to a wind power tower with long and short legs. Background technique [0002] The tower is the main supporting part of the wind turbine, and its design reliability is the guarantee for the safe operation of the wind turbine. The environmental conditions in which wind turbines operate are very harsh, so the tower must not only have sufficient strength and rigidity to withstand various loads caused by the natural environment and the operation of the wind power system, but also avoid resonance between the tower and the impeller, so the design of the tower is It is a very important link in the design of wind turbines. Adopting a reasonable tower type will directly affect the safety and economy of wind turbines. At present, the structural forms of wind power towers mainly include cone-shaped towers and lattice towers. [0003] (1) Tapered tower [0004] The cone-shaped tower is the most typica...

Problems solved by technology

[0007] The above several wind power towers also have a common disadvantage, that is, the traditional wind power tower adopts the form of flat legs. When the slope is in the mountainous terrain, the root opening of the tower legs is relatively large, considering the construction and other aspects. Requirements, a large amount of earth and stone excavation is required, which will not only cut down or destroy the surrounding plants, but also pile up the excavated earth and stone around the foundation. vegetation damage and property loss, and even cause safety hazards to wind power towers
