Patent ID: 6853096

Claim:
A wind turbine adapted to generate electricity using wind power, comprising: rotation shaft means for transmitting wind power to a generator, and a plurality of blades secured to the rotation shaft means to be spaced apart one from another in a circumferential direction; wherein each blade has a lattice composed of transverse lattice elements and longitudinal lattice elements which are plaited to cooperatively define a plurality of spaces; and wherein, in each blade, each of several rotation adjustment pieces is coupled to a portion of a transverse or longitudinal lattice element to be capable of rotating between a closing position where it closes a predetermined number of the spaces and an opening position where it opens a predetermined number of the spaces, so that several rotation adjustment pieces can cover an entire surface of each blade and thereby the blades as a whole can be rotated irrespective of a wind direction; whereby, depending upon a rotated position, the rotation adjustment pieces can open or close the spaces, so that electricity can be generated using wind force applied to the rotation shaft means through rotation adjustment pieces.
