Stepped composite material wind power anti-seismic tower barrel

Abstract

The invention relates to a stepped composite material wind power anti-seismic tower barrel. The stepped composite material wind power anti-seismic tower barrel is composed of at least two tower barrelsections vertically arranged from bottom to top and connecting units connecting adjacent tower barrel sections. The tower barrel sections are made by stacking a plurality of tower barrel units, wherein the tops and bottoms of the tower barrel units are provided with first stiffening ribs with a plurality of first through holes correspondingly, and adjacent tower barrel units are fixedly connectedtogether through first bolts. The connecting units are in frustum shapes. The tower barrel units and the connecting units comprise inner steel plates and outer steel plates correspondingly, and UHPClayers are filled between the inner steel plates and the outer steel plates. The tops and bottoms of the connecting units are provided with second stiffening ribs correspondingly, wherein the second stiffening ribs extend to the interiors of the connecting units and are horizontally arranged and provided with a plurality of second through holes, the connecting units are fixedly connected with adjacent tower barrel units through second bolts, the second bolts penetrate through the first through holes and the second through holes. The stepped composite material wind power anti-seismic tower barrel can be modularized and prefabricated, so that the production and installation efficiency is improved.

Description

technical field [0001] The invention relates to a gradient composite material wind power anti-seismic tower, which belongs to the technical field of wind power generation. Background technique [0002] The wind power tower is the tower pole of wind power generation, which is the main load-bearing structure of the wind power generation unit. It is arranged under the wind turbine host and the wind wheel, supporting the wind turbine host and the wind rotor weighing dozens of tons, and can also absorb wind power. Unit vibration. Depending on the regional distribution of the wind field and the height of the main wind area, the height of the wind turbine tower is also different, usually the height is more than tens of meters. A wind power tower that can be put into operation must not only ensure the dynamic stability of the whole machine, that is, the design of the tower must not only meet the requirements of aerodynamics, but also the stress on the tower is extremely complicated...

AI Technical Summary

Problems solved by technology

In order to ensure the strength of the tower tube, the tower wall of the existing steel plate tower tube, that is, the thickness of the steel plate must be very thick, so the consumption of steel plates is large, resulting in a high cost of making the tower tube

[0005] However, the concrete tower needs to be prestressed and stretched after the assembly is completed, and the prestress is easy to fail. After the prestress fails, the tower will be broken or cracked; and the tower made of steel plate has limited bearing pressure. risk of crushing
