WIND POWER GENERATING DEVICE, CAPABLE OF ACHIEVING HIGH OUTPUT AND HIGH EFFICIENCY OF WIND ENERGY BY MINIMIZING THE RESISTANCE TO WIND HAVING REVERSE DIRECTION

摘要

PURPOSE: A wind power generating device is provided to maximize wind utilization efficiency by minimizing the resistance to wind by opening a vent port for wind having reverse direction.;CONSTITUTION: A wind power generating device comprises a rotating shaft(10), blades(11) and a generator. The blades are installed around the rotating shaft. The blades are fixed to the rotating shaft to rotate with them. The blade comprises an inner vent port(13), an inner blade(14), a middle vent port(15) and an outer blade(16). The blade further comprises an outer vent port(17) and upper and lower boards. The outer vent port of the blade is, in a straight line, connected to the main beams of upper and lower frames at an angle of 45°. The upper and lower frames are, in a straight line, connected to the rotating shaft. The 45° is the maximum rotatable angle of a variable blade(18).;COPYRIGHT KIPO 2011
