PURPOSE: A power generating device using buoyancy is provided to rotate a sprocket by using a rising (moving) motion of a buoyant member and to obtain power by the rotation of the sprocket. CONSTITUTION: A power generating device using buoyancy includes a liquid jacket (100), an upper end sprocket (210), a lower end sprocket (220), a first and a second frame (310,320), and multiple buoyant members (400). The liquid jacket stores liquid inside. The upper and the lower sprocket are mounted rotatably on the upper and the lower end of the liquid jacket respectively. The first and the second frame are installed on both sides of the upper and the lower end sprocket. The multiple buoyant materials are arranged inside a first and a second frame, and mounted on the upper and the lower sprocket in a mutually connected state and in a caterpillar shape. The first frame is positioned in liquid inside the liquid jacket and on the outside of the liquid jacket of the second frame; and therefore, the buoyant member is raised by buoyancy. The upper and the lower end sprocket are rotated by the movement of the buoyant member. |
