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.

The present invention provides a steel structure cooling tower, including a truss system, a hyperbolic enclosure plate system and an opening-closing system. Hoop trusses and meridional trusses are connected crisscross to form a force transfer structure of the steel structure cooling tower, thereby improving the overall stability of a tower body of the cooling tower and reducing the wind pressure on the tower body. An enclosure plate is mounted on the hoop truss by an enclosure plate bracket assembly, the opening-closing system is laid on the hoop truss, and a wind and rain sensor is installed on a hoop truss on the top of the tower body of the cooling tower. When typhoon rain exceeds a limiting value, an opening-closing posture of the hyperbolic enclosure plate is adjusted, so that the steel structure cooling tower can open the enclosure plate to reduce a wind load acting on the tower body.
