Plate frame type tower frame for wind power generator (set) and manufacturing method of plate frame type tower frame

Abstract

The invention relates to a plate frame type tower frame for a wind power generator (set). The plate frame type tower frame comprises a barrel made of metal materials and a framework structure arrangedon the inner side face of the barrel according to the preset type so as to strengthen the barrel through the framework structure, wherein the barrel is provided with an inner side face and an outer side face opposite to the inner side face. Accordingly, the structure performance of the tower frame is enhanced through the framework structure instead of the manner of increasing the wall thickness and the diameter of the barrel, accordingly, it is effectively ensured that the tower frame meets the structure performance requirement, the wall thickness and the diameter of the barrel are reduced, the integral cost of the tower frame can be reduced, meanwhile, the road transportation maximum-diameter limitation regulated by the nation can be achieved, and accordingly the transportation problem is solved. Meanwhile, the phenomenon of resonance of the tower frame and the wind power unit can be effectively prevented.

Description

technical field [0001] The present application relates to the field of wind power generation, in particular to a panel-type tower for a wind power generator (set) and a manufacturing method thereof. Background technique [0002] With the continuous development and utilization of wind resources, the number of wind areas on land with relatively stable wind speed and high annual average wind speed within the safety level of wind turbines is decreasing. The current situation of the gradual shortage of low-altitude wind resources has prompted developers to continuously increase the hub height of wind turbines (sets) (hereinafter referred to as "fans") and increase the diameter of the impeller to obtain greater wind energy. Increased hub heights and increased impeller diameters require correspondingly taller and taller towers used to support wind turbines. [0003] The ever-increasing height of the tower poses greater challenges to its structure and performance. Although there a...

AI Technical Summary

Problems solved by technology

Although there are already some high-altitude towers, these towers have some defects more or less, for example, the transportation problem that is difficult to solve due to the large diameter of the ultra-high tower cylinder; the wind power of the ultra-high flexible tower The unit adopts a control strategy to reduce power generation to avoid resonance between the flexible tower and the wind turbine, which poses a major safety hazard. There have been many collapse accidents of ultra-high flexible towers at home and abroad
