Abstract
An active folding wind turbine capable of resisting severe typhoons is provided. Each wind turbine blade includes an upper blade part and a lower blade part that are hinged to each other by a hinge device. A motor transmission system is installed in the lower blade part, is connected to the hinge device in a transmission manner, and can drive the upper blade part to rotate relative to the lower blade part through the hinge device, so that the wind turbine blade is bent. When the upper blade part rotates to an end of a travel, a blade tip of the upper blade part is propped against an upper end of the lower blade part of an adjacent wind turbine blade. A winch is built in an upper portion of the lower blade part of the wind turbine blade, and is provided with a cable.
