| titleOfInvention |
A kind of variable-wall-thickness wind tower for wind power generator and manufacturing method thereof |
| abstract |
A variable-wall-thickness wind tower for wind turbines and a manufacturing method thereof belong to the technical field of wind power equipment. The wall thickness tower is assembled into a variable wall thickness wind tower through the flange between the variable wall thickness towers. The manufacturing method includes cutting and cutting a variable-thickness steel plate, forming an arc-shaped sheet by pressure forming, and longitudinally welding the arc-shaped sheet into a variable-thickness tower. The invention can obviously save the amount of steel used for preparing the wind tower, greatly reduce the length of the welding seam, thereby saving energy and reducing consumption and reducing carbon emissions. |
