Abstract:
1. A wind driven power generating system of single-rotor type in which a horizontal and vertical shafts are combined, the wind driven power generator comprising: a) an aerodynamic unit rotatably mounted at the top of a tower having a certain height; b) a plurality of rudders for aligning the aerodynamic unit with the direction of wind, the rudders being radially formed on the outer surface of the aerodynamic unit; c) a horizontal shaft rotatably and horizontally mounted in the aerodynamic unit, wherein one end of the horizontal shaft is projected outwardly from a back end of the aerodynamic unit and the other end of the horizontal shaft remains inside of the aerodynamic unit and is provided with a first bevel gear; d) a blade attached to rear end of the horizontal shaft, wherein the blade is rotated by the wind and thus rotates the horizontal shaft; e) blade variation means disposed at rear portion of the aerodynamic unit for slanting the blade backwards and forwards, depending on the wind pressure; f) a power generator installed inside the tower; and g) a vertical shaft for transmitting the rotating power of the horizontal shaft to the power generator, wherein one end of the vertical shaft is provided with a second bevel gear, which is engaged with the first bevel gear, and the other end thereof is connected to a rotor shaft of the power generator, wherein the blade variation means comprises;
