Patent ID: 7777363

Claim:
A wind engine, comprising a vertically positioned central rotor ( 1 ); a power generation part ( 3 ); an opening adjustment positioner ( 7 ); a brake ( 8 ); a power distributor ( 21 ); and a power switch ( 22 ); wherein said vertically positioned central rotor ( 1 ) has one unit of several groups of frameworks ( 2 ) evenly distributed around it, or has at least two units of several groups of frameworks ( 2 ) distributed longitudinally and consecutively along its length; each group of said frameworks ( 2 ) is provided with at least one set of said power generation parts ( 3 ) which can turn within a set range; a profile frame ( 3 a ) of said power generation parts ( 3 ) has support shafts ( 3 c ) of the same horizontal central line each positioned at ½ or ⅖ to ⅗ of the longitudinal height of the left and right side frames, and are installed with a bearing ( 3 d ) onto the left and right columns ( 2 c , 2 d ) of the corresponding frameworks ( 2 ), to form a structure which is centered around the support shaft and can adapt to the wind direction changes, so that during the reversing wind stroke it will automatically reverse to be in a state where its entire plane is almost horizontal to the air flow direction without any air flow resistance, and during the fair wind stroke it will automatically return to a closed vertical state where it bears the pushing force perpendicular to the air flow, thereby driving the rotation of the entire system to form a wind engine; a bottom frame of said profile frame ( 3 a ) has a set of reversing and return boosters ( 3 g ) installed on one side that assists the power generation parts to reverse and lift and controls the reversing speed in case of a high wind speed; at columns ( 2 c , 2 d ) side of all groups of frameworks ( 2 ), there is said brake ( 8 ) for the power generation parts ( 3 ) for controlling the operation or stop of the wind engine and said opening adjustment positioner ( 7 ) for limiting the lifting angle of the power generation parts mounted on an integrated assembly bracket ( 2 i ); and said brake ( 8 ) is electrically connected to said power distributor ( 21 ) installed on the lower shaft part ( 1 f ) or upper shaft part ( 1 e ) of the central rotor ( 1 ) via conductor or cable, and can control the make/break of the circuit via said power switch ( 22 ) of the power distributor ( 21 ), so that said brake ( 8 ) can release or limit the reversing of the power generation parts.
