[0002] Wind energy is a clean, pollution-free, renewable energy source. The use of clean energy such as wind energy can reduce carbon emissions. Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind energy can be converted into the electrical energy people need through wind turbines. Wind turbine towers mainly play a supporting role in wind turbines and absorb the vibration of the unit. Wind turbine towers are the tower poles for wind power generation, which enable wind turbines to utilize wind energy more efficiently. However, existing wind turbine towers are hollow structures. There is no supporting structure inside the wind turbine tower, and the outer wall is a smooth structure. Therefore, when the wind is strong, the wind turbine tower is prone to bending and falling due to the large wind resistance, which in turn causes damage to the wind power generation equipment.
