The invention provides a buoyancy type thruster. The buoyancy type thruster comprises one or more thruster body units. The propeller body unit comprises a conical head, a buoy and a propeller, fin plates are arranged on the outer wall of the buoy, and a buoyancy plate and the buoy can be arranged according to needs; the buoyancy plate is a flat plate which forms a corresponding pitch angle with the axial direction of the propeller body unit or a curved plate which is subjected to flow optimization design, and when the propeller moves forwards, incoming flow flows through the buoyancy plate to generate buoyancy; the buoy is a streamlined component and is generally of a hollow structure or made of light materials. The buoyancy type propeller provided by the invention is small in sailing resistance, high in propelling efficiency and flexible in use mode, can obviously reduce the flow resistance of a ship body in the sailing process, achieves a higher sailing speed, reduces the energy consumption in the sailing process, is obvious in energy-saving and emission-reducing effects, and improves the economical efficiency. The device can be widely applied to various surface ships and can also be used for water sports projects.
本发明提供了一种浮力式推进器,包括一个或多个推进器本体单元。推进器本体单元包括锥形头部、浮筒和螺旋桨,浮筒外壁设置鳍板,并可根据需要设置浮力板、浮漂;浮力板是与推进器本体单元轴向之间呈相应俯仰角的平板或是经过流动优化设计的曲面板,推进器向前运动时,来流流经浮力板可产生浮力;浮漂是流线型的构件,通常是空心结构或者由轻质材料构成。本发明提供的浮力式推进器航行阻力小,推进效率高,使用方式灵活,可明显减小船体在航行过程中的流动阻力,达到更高航速,降低航行过程中的能量消耗,节能减排效果明显,提高经济性。本发明可广泛应用于各类水面舰船,也可以用于水上运动项目。
