Problems solved by technology

However, at present, most of the wind power towers in China are steel towers. Steel towers have problems such as high production costs (the cost of steel towers increases exponentially with height), easy corrosion, high maintenance costs, and difficult transportation and installation.
In addition, due to the limited pressure and tensile capacity of the steel tower, when the height of the tower is large, the bottom of the steel tower is prone to cracking and buckling due to stress overload, which poses a greater safety hazard

Abstract

The invention relates to the technical field of wind power tower cylinders, and discloses a variable-cross-section assembly type wind power tower cylinder which comprises a first cylinder section, a second cylinder section and a third cylinder section which are sequentially connected from top to bottom. One end of the second cylinder section is detachably connected with one end of the first cylinder section, and the other end of the second cylinder section is connected with one end of the third cylinder section; in the direction from the end, connected with the second cylinder section, of thethird cylinder section to the free end of the third cylinder section, the cross section area of the third cylinder section is gradually increased; and a hollow part is arranged on the side wall of thethird cylinder section. According to the variable-cross-section assembly type wind power tower cylinder, the third cylinder section can increase the contact area between the wind power tower cylinderand the ground, the bottom bearing capacity is high, and the overall stability of the wind power tower cylinder is improved; and meanwhile, transportation and installation are easy, convenient and rapid, and workloads of operators are reduced.

Description

Technical field[0001]The invention relates to the technical field of wind power towers, in particular to a variable cross-section assembled wind power tower and a construction method for the wind power tower.Background technique[0002]The wind power tower is an important part of the wind turbine. Its function is to support the nacelle and the wind wheel, lift the wind wheel to a corresponding height, and obtain enough wind power to drive the generator set to generate electricity. With the continuous maturity of the wind power industry, domestic development of wind energy resources in low wind speed regions and the central and eastern regions has become increasingly fierce. Increasing the height of the hub in places with good wind shear index can effectively increase the power generation of wind turbines. Therefore, increasing the height of wind power towers has become a major trend. However, most of the current domestic wind power towers are steel towers, and steel towers have proble...
