Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] Such as figure 1 As shown, the specific embodiment of the construction method of the wind power generating set tower provided by the present invention includes:

[0026] Step 11, welding the array of shear keys and / or shear studs on the outer wall of the steel tower section.

[0027] Due to the enlargement of wind power generating units, the height of the tower is getting higher and higher, and the shear stress it bears is increasing. Therefore, when the st...

Abstract

The invention discloses a constructing method of a wind power generator set tower frame and the wind power generator set tower frame, relates to the wind power generation technology and is invented by reaching the goal of improving the rigidity of the tower frame on the basis without increasing the cost of the steel tower frame. The constructing method of the wind power generator set tower frame comprises the steps that anti-shearing keys and / or anti-shearing toggle pin arrays are welded at the outer wall of a steel tower tube section; a concrete layer is sprayed and coated at the outer wall of the steel tower tube section; and the steel tower tube sections are connected to form the tower frame in the height direction. The wind power generator set tower frame comprises a steel tower tube and the concrete layer sprayed and coated at the outer wall of the steel tower tube, wherein the anti-shearing keys and / or the anti-shearing toggle pin arrays are welded at the outer wall of the steel tower tube, and the anti-shearing keys and / or the anti-shearing toggle pin arrays are covered by the concrete layer. The constructing method and the wind power generator set tower frame are used for wind power generation.

Description

technical field [0001] The invention relates to wind power generation, in particular to a construction method of a tower of a wind power generator and a tower of a wind power generator. Background technique [0002] Most of the towers currently used for wind turbines are constructed of steel towers. The specific construction method is to connect the multi-section steel tower sections with smaller heights through flanges in the height direction to form a steel tower with larger heights. As the power of wind turbines increases, the diameter of the impeller increases, and accordingly the height of the tower increases, and the load on the tower increases, so the rigidity of the tower is also raised. higher and higher requirements. [0003] There are mainly two methods for increasing the rigidity of the steel tower in the prior art: the first is to increase the wall thickness of the steel tower section, and the second is to increase the outer diameter of the steel tower section...
