Problems solved by technology
With the enlargement of wind turbines, higher requirements are placed on the height and rigidity of the tower, and the required wall thickness and diameter of the tower are greatly increased, resulting in a significant increase in the amount of steel used for the tower
The increase in the amount of materials also brings problems such as difficulties in transportation and hoisting, and high maintenance costs in the later period

Embodiment Construction
[0018] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.
[0019] The invention provides a fan tower, such as Figures 1 to 2 Shown is a specific embodiment of the fan tower, which is composed of a cylinder wall 1 and steel flanges 2 at both ends. The cylinder wall 1 is formed by rolling several sections of longitudinally variable-thickness steel plates and welded or bolted to each other. , the steel flange 2 is welded to both ends of the rolled and welded cylinder wall 1 .
[0020] In the above embodiment, if figure 1 As shown, the longitudinally variable-thickness steel plate can adopt a variety of specifications, including different cross-sectional shapes and sizes.
[0021] It should be noted that the cross section of the fan tower can be circular or polygonal.
[0022] The present invention provides a fan tower applying the fan tower described in the above embodiments, such as image 3 Shown is a ...

The invention discloses a tower barrel for wind turbines and a wind turbine tower employing the same and is intended to solve the problem that assembly of large-height wind turbine towers with traditional steel tower barrels experiences weak stress-bearing parts due to sudden change in the wall thickness and high steel consumption on the whole. The tower barrel for wind turbines comprises a barrelwall and steel flanges; the barrel wall is made of a vertical variable-thickness steel plate that has different sectional shapes, and the steel flanges are welded to two ends of the barrel wall. Thewind turbine tower comprises a plurality of tower barrels stacked sequentially in vertically upward direction; all the tower barrels may be the vertical variable-thickness tower barrel, or part of thetower barrels may be the vertical variable-thickness tower barrel.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a fan tower and a fan tower using the same. Background technique [0002] The wind turbine tower is an important part of the wind power generation system, and its construction cost can account for about 20% of the total construction cost. The cylindrical tower has good structural performance, convenient and safe manual maintenance, and beautiful appearance, which is the mainstream of design and manufacture at present. With the enlargement of wind turbines, higher requirements are put forward for the height and rigidity of the tower, and the required wall thickness and diameter of the tower are greatly increased, resulting in a significant increase in the amount of steel used for the tower. The increase in the amount of materials also brings problems such as difficulties in transportation and hoisting, and high maintenance costs in the later period. At the same tim...
