The underwater propeller comprises a main shaft, a water suction impeller, a synchronous propelling impeller, a water inlet baffle disc and a centrifugal impeller, and the water suction impeller, the synchronous propelling impeller, the water inlet baffle disc and the centrifugal impeller are sequentially installed on the main shaft. According to the working process of the underwater propeller, the water suction impeller rotates to suck water from the outside, the synchronous propelling impeller and the centrifugal impeller rotate synchronously, the water is pushed to the direction of the centrifugal impeller, and the water does circular motion along with rotation of the centrifugal impeller and is subjected to the centripetal force effect of a shell of the centrifugal impeller. Due to the fact that the opening is formed in the upper area of the water inlet baffle disc, water enters the centrifugal impeller from the opening of the water inlet baffle disc, the water outlet is formed in the lower portion of the centrifugal impeller shell, and the up-down centrifugal force difference in the centrifugal impeller shell is caused through the up-down asymmetric water inlet and outlet mode in the centrifugal impeller shell; kinetic energy of water rotating rapidly is converted into kinetic energy of the underwater propeller. According to the underwater propeller, centrifugal force is utilized to generate propulsive force, and the propulsive efficiency of the underwater propeller is effectively improved.

    本发明公开一种水下推进器,包括主轴和依次安装在主轴上的吸水叶轮、同步推进叶轮、进水挡盘以及离心叶轮,离心叶轮的外部设有离心叶轮壳体;该水下推进器工作过程:吸水叶轮旋转用以将水从外部吸入,同步推进叶轮与离心叶轮同步旋转,并将水推向离心叶轮方向,水随离心叶轮旋转做圆周运动,且受到离心叶轮壳体的向心力作用。由于进水挡盘上部区域设有开口,水从进水挡盘的开口进入离心叶轮,离心叶轮壳体下部设有排水口,以通过离心叶轮壳体内部上下不对称的进出水方式引起离心叶轮壳体内部上下离心力差,同时,快速旋转的水的动能转化为水下推进器的动能。本发明的水下推进器利用离心力而产生推进力,有效地提高水下推进器的推进效率。
