[0002] Wind turbines are electrical equipment that converts wind energy into mechanical work, which drives the rotor to rotate and eventually outputs alternating current. Wind turbines are generally composed of wind rotors, generators (including devices), direction regulators (tail fins), towers, speed limit safety mechanisms, and energy storage devices. At present, wind turbine operators must climb a tower ladder of nearly 100 meters before entering the cabin. When passing through the passage on each tower platform, the operator needs to push open the cover plate before passing through.
