Rotor driven windmill for use in wind poor area, has rotors that are pivoted, where force acts on principal axis to cause rotating motion at axis, and windmill is adapted to change of rotor rotating direction in multiple wind directions

摘要

The windmill has cylindrical or conical shaped rotors (2) that are pivoted, where force due to wind flow acts upon a principal axis (1), when the rotors move around their own axis, to cause a rotating motion at the principal axis. A side of the rotor with a large diameter is provided at an outer end of the rotor. The rotor is integrated in a partial tube section, whose inlet and outlet are enlarged and bent outwardly for forwarding wind flow. An electronic control adjusts the efficiency of the windmill at the principal axis. The windmill is adapted to the change rotor rotating direction in multiple wind directions.
