The invention discloses a rim propeller. The rim propeller comprises a rotating shaft, a shell, a stator and a rotor, the rotating shaft is of a hollow and horn-shaped structure and is movably installed in end covers on the two sides of the shell through a bearing, and the rotating shaft comprises a large end part, a small end part and a gradual change part connecting the large end part and the small end part; a propeller is fixedly mounted on the inner ring of the large end part, and the rotor is fixedly mounted on the outer ring of the small end part; the stator is fixedly mounted on the shell and corresponds to the rotor; and a rectifying piece is arranged at the rear end of a propeller, the rectifying piece is fixed to a flow guide cover through a connecting rod penetrating through a center channel of the propeller, and the flow guide cover is fixedly installed on the shell. The structure characteristics of a pipeline and the the propeller are combined, the Venturi effect is utilized, the contradiction between a high-power driving device and a limited installation space in the rim propeller and the utilization problem of vortex motion energy in the pipeline are well solved, and the propulsion power and the propulsion efficiency of the rim propeller are greatly improved while the small size of the rim propeller is guaranteed,.
本发明公开了一种轮缘推进器,包括有转轴、壳体、定子及转子,所述转轴呈中空、喇叭状结构,通过轴承活动安装在壳体的两侧的端盖中,包括有大端部、小端部及连接大端部与小端部的渐变部;所述大端部内环固定安装有螺旋桨,所述小端部外环固定安装有转子;所述定子固定安装在壳体上,与所述转子相对应;所述螺旋桨后端设有整流片,所述整流片通过贯穿螺旋桨中心通道的连杆固定在导流罩上,所述导流罩固定安装在壳体上。本发明结合其管道及螺旋桨的结构特点,并利用了文丘里效应,极好地解决了轮缘推进器中大功率驱动装置与有限的安装空间之间的矛盾及管道中涡动能量的利用问题,在保证轮缘推进器小体积的同时,大大提高了其推进功率及推进效率。
