<p>PURPOSE: A vertical-axis power generation device with a V-arm structure is provided to remove a rotary shaft because blades and a generator are connected by coupling the outer bent and protruded circumference of upper and lower rotary plates integrated with the generator to blade arms. CONSTITUTION: A vertical-axis power generation device with a V-arm structure comprises an upper rotary plate (11), a lower rotary plate (12), blade arms (30), and blades (20). The upper and lower rotary plates are coupled to the top and the bottom of a generator (10) and have protruded portions bent from the outer circumference of the upper and lower rotary plates at regular intervals. Each blade arm comprises an arm body and a blade holder with an insertion groove. One end of the arm body is coupled to the protruded portion of the upper or lower rotary plates. The blade holder is bent from the other end of the arm body. The blades are inserted in the insertion grooves of the blade holders and are coupled to the blade holders by stators and bolts.</p> |
