The invention relates to the technical field of ship propulsion, in particular to a radial water inflow turbine propeller. Comprising a turbine and a driving device, the turbine is of a hollow structure formed by connecting a plurality of uniformly distributed turbine blades between two discs, a nozzle is arranged in the center of the front-end disc, and a turbine shaft which is integrated with the rear-end disc and is provided with an inner hole is arranged in the center of the outer side of the rear-end disc; the driving device is a conventional device, the outer side of a driving shaft of the driving device is sleeved with a shaft sleeve, the driving shaft is inserted into an inner hole of a turbine shaft, the driving shaft extends out of a disc at the rear end of a turbine and enters an inner cavity of the turbine, and the turbine and the driving shaft are fixed through a turbine lock nut. The front end of the nozzle is a round tube, and the rear end is a conical hole which is communicated with an inner hole of the round tube at the front end. The turbine blades are arc-shaped long-strip pieces, are integrated with the turbine front-end disc and the turbine rear-end disc and are arranged on the edges of the turbine front-end disc and the turbine rear-end disc, the middles of the turbine blades protrude outwards, the outward protruding height of the front sides of the turbine blades is larger than the outward protruding height of the rear sides of the turbine blades, and protruding arc-shaped slopes are arranged between the front sides and the rear sides of the turbine blades.

    本发明涉及船舶推进技术领域,一种径向进水的涡轮推进器。包括涡轮、驱动装置;涡轮为两个圆盘中间用数个均布的涡轮叶片连接的中空结构,前端圆盘中心为喷嘴,后端圆盘外侧中心设有与后端圆盘一体结构且带内孔的涡轮轴;驱动装置为常规装置,其驱动轴外侧套装轴套,驱动轴插装在涡轮轴内孔中,驱动轴探出涡轮后端圆盘进入涡轮内腔,用涡轮锁母将涡轮与驱动轴固定。喷嘴前端为圆管,后端为圆锥孔,圆锥孔与前端圆管内孔连通。涡轮叶片为弧形长条片,与涡轮前端圆盘和后端圆盘为一体结构,设置在涡轮前端圆盘和后端圆盘边缘,涡轮叶片中间向外凸起,涡轮叶片前侧向外凸起的高度大于后侧向外凸起的高度,涡轮叶片前侧与后侧之间为凸起的弧形斜坡状。
