Abstract: A buoyant rotation device has a casing, a rotating cylinder, and multiple floating elements. The casing has a body with an opening and two connecting boards. The rotating cylinder is rotatably mounted in the casing and has an inner tank, an outer tank, multiple dividing panels, and two side panels. A part of the rotating cylinder extends out of the body. The inner tank has a holding shaft. The outer tank is mounted around the inner tank to form an annular space, and has multiple main inlet holes formed through the outer tank and communicating with the annular space. The dividing panels are deposited in the annular space at spaced intervals between the inner tank and the outer tank to form multiple separate spaces not communicating with each other. Each one of the multiple floating elements is deposited in one of the multiple separate spaces of the rotating cylinder.
