However, traditional wind turbines have a simple mast structure and a fixed height. Firstly, they cannot flexibly adjust the height according to changes in wind resources, thus limiting the improvement of wind power generation efficiency. Secondly, the inability to lower the height during strong winds makes the turbine and blades extremely susceptible to damage. Summary of the Invention

It comprises three parts: a turbine head, a mast, and a windbreak. Through a unique sliding lifting structure design, the height of the wind turbine mast can be flexibly adjusted. In windy weather, the turbine head and the mast can retract and be hidden inside the windbreak, preventing damage to the turbine head. This design not only optimizes the wind turbine's wind capture effect and improves power generation efficiency, but also enhances the stability and safety of the wind turbine and its blades under different wind conditions.
