The present invention relates to a wind driven power generating system of single rotor type in which a horizontal and vertical shafts are combined. Specifically, the invention relates to a wind driven power generating system in which, under blowing of strong wind, the rotating blade is automatically and variably slanted backwards by means of a spring force without any pitch control while directing against the wind, thereby protecting the system and continuing the generation of electricity.
The wind driven power generating system includes:
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 outwardly from the backend 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 the 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 the 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.
