Vertical axis wind turbine generator

A vertical axis wind turbine generator in which a rotary shaft is provided to be perpendicular to the ground, the vertical axis wind turbine generator comprising:

• at least two conical frames (130) which are provided in layers and each of which has an inner space;
• at least three poles (140) vertically passing through an outer circumference of the conical frame (130) to be fixed to the ground;
• a rotor blade rotating shaft (110) installed vertically and configured to rotate between the conical frame (130) and the conical frame (130);
• at least three rotor blades (120), each of which is divided into a fixed blade (120a) and movable blades (120b, 120c and 120d) and has a center in which a wind hole having a circular shape is defined, and which are connected to the rotor blade rotating shaft (110) at the same interval;
• wherein the fixed blade (120a) is connected to the rotor blade rotating shaft (110) through a fixed blade connecting frame (120g);
• wherein a first movable blade (120b) is connected to the inside of the fixed blade (120a) through four elastic bands (120f),
• wherein two of the four elastic bands (120f) are connected to upper left and right portions of the inside of the fixed blade (120a) and upper left and right side surfaces of the first movable blade (120b), and the other two elastic bands (120f) are connected to lower left and right portions in the same method,
• wherein with the fixed blade (120a) connected to the first movable blade (120b) as above, when a wind pressure is generated by a backwind, a portion, which has a small diameter, of the first movable blade (120b) is inserted to protrude into the wind hole of the fixed blade (120a), and a portion having a large diameter is in a state of being hooked with the wind hole of the fixed blade (120a);
• wherein a second movable blade (120c) is connected to the inside of the first movable blade (120b) through four elastic bands (120f) in the same method as the fixed blade (120a) and the first movable blade (120b), wherein when a wind pressure is generated by the backwind, a portion, which has a small diameter, of the second movable blade (120c) is inserted and protrudes from a wind hole of the first movable blade (120b), and a portion having a large diameter is in a state of being blocked by the wind hole of the first movable blade (120b);
• wherein a third movable blade (120d) is connected to the inside of the second movable blade (120c) through four elastic bands (120f) in the same method as above, wherein when a wind pressure is generated by the backwind, a portion, which has a small diameter, of the third movable blade (120d) is inserted and protrudes from the wind hole of the second movable blade (120c), and a portion having a large diameter is in a state of being blocked by a wind hole of the second movable blade (120c) so that the rotor blade is completed, wherein when the wind pressure of the backwind is applied, the entire configuration of the rotor blade (120) is provided as a bowl shape to generate the wind pressure of the backwind to the maximum;
• wherein the rotor blade (120) to which a headwind is applied, the movable blades (120b, 120c, 120d) are connected to each other with maintaining spacing inside the fixed blade (120a) so that the rotor blade (120) has a shape in which the wind hole is opened;
• an accelerating gear (150) installed in the conical frame (130) and connected to each of upper and lower ends of the rotor blade rotating shaft (110);
• and
• a power generating device (M) connected to the accelerating gear (150) and configured to produce electricity.
