Fan tower structure

Abstract

The invention discloses a fan tower structure which comprises a tower platform, a fan tower cylinder arranged above the tower platform, a plurality of horizontal rotating bearing pieces arranged on the periphery of the tower platform, a plurality of fan tower cylinder inclined struts arranged on the periphery of the fan tower cylinder and a plurality of fan tower cylinder legs arranged below the tower platform; each horizontal rotating bearing piece is connected with the tower platform, one fan tower cylinder inclined strut and two fan tower cylinder legs, and each fan tower cylinder inclined strut is connected with the fan tower cylinder and one horizontal rotating bearing piece; a plurality of pre-stressed anchor cables are arranged in each fan tower cylinder inclined strut and each fan tower cylinder leg in a penetrating mode, and the pre-stressed anchor cables arranged in the fan tower cylinder legs in the penetrating mode are connected with pre-stressed anchor cable heads on the tower foundation and the pre-stressed anchor cables in the corresponding fan tower cylinder inclined struts respectively. The fan tower structure has the advantages that the overall stress is safer and more reliable, the structural pressure resistance, torsion resistance, fatigue damage resistance and overall rigidity are remarkably improved, the steel consumption is lower, and the construction cost is relatively low.

Description

Technical field [0001] The present invention relates to the field of fan power generation facilities, and in particular, to a fan tower structure. Background technique [0002] Wind power tower belongs to a large load and needs to withstand a loop load. When height is within 90m, it mainly adopts a pure steel tube structure; when the height reaches 90m, it is necessary to increase its cross-sectional size to meet the structural stiffness requirements, but when the pure steel tube structure is used, there is a large structure size. It is unable to resolve the transportation of bridges and culverts of the highway, in order to overcome this problem, the current 90m height is usually used, the concrete + pure steel cylinder and purely preproving concrete structures are used, but the form of this class also exists. Such as: the shortcomings such as large engineering volume, difficult, long construction cycle, high cost, structural reliability, and fatigue risk. Inventive content [0...

AI Technical Summary

Problems solved by technology

When the height is less than 90m, it mainly adopts a pure steel cylinder tower structure; when the height reaches more than 90m, its cross-sectional size must be increased to meet the structural rigidity requirements, but if a pure steel cylinder structure is used, the structure size is large, It cannot solve the problem of the bridge and culvert size limitation of the expressway during transportation. In order to overcome this problem, the wind towers with a height of 90m or more are usually used in concrete + pure steel tube and pure prefabricated concrete tube structures, but this type of structure also exists Disadvantages such as: large amount of engineering, difficult hoisting, long construction period, high cost, poor structural reliability and fatigue risk
