<p>PURPOSE: A vertical axis aerogenerator with a variable blade angle structure is provided to have a simple structure and to reduce production and maintenance costs since the angle is automatically controlled for a wind receiving area to be changed between maximum and minimum without using an auxiliary blade. CONSTITUTION: A vertical axis aerogenerator with a variable blade angle structure has a connection rod (60) on which up-down weights (80,80') protruded in the longitudinal direction of blades (20,20') are fixed. A rail (200) for the up-down weights is installed on the upper part of a tower (10). The rail is provided for the up-down weights to travel by the rotation of blades which rotate around a vertical rotary shaft (40), and for the height of the up-down weights to be changed in a fixed section. The blades are in a vertical state of a fixed section, and in a horizontal state of other fixed sections when the blades are rotated around the vertical rotary shaft.</p> |
