The invention provides a multistage propeller ship propulsion device comprising a propeller shell, a common propeller thruster and a hub motor thruster. The common propeller thruster is fixedly installed on one side of a water inlet, and a hub motor driver is fixedly installed on one side of a water outlet; the common propeller thruster comprises a propeller, a gear box and a suspension arm, and the hub motor thruster is composed of a stator assembly fixed to the propeller shell and a propeller rotor assembly matched with the stator assembly. Water is pressurized and accelerated to pass through the conical through hole in the middle of the propeller shell through rotation of a common propeller and is pressurized and accelerated again through the propeller rotor assembly of the hub motor thruster, and large thrust is formed, so that a ship is propelled to rapidly travel.
本发明提供的一种多级螺旋桨船舶推进装置,由推进器外壳、普通螺旋桨推进器和轮毂电机推进器组成,入水口一侧安装固定普通螺旋桨推进器,出水口一侧安装固定轮毂电机驱动器,普通螺旋桨推进器包括螺旋桨、齿轮箱和吊臂,轮毂电机推进器由固定在推进器外壳的定子总成和与其配合的螺旋桨转子总成组成。普通螺旋桨的旋转将水加压加速通过推进器外壳中间的锥形通孔,经过轮毂电机推进器的螺旋桨转子总成再次加压加速,形成很大的推力,从而推进船舶快速行驶。
