The invention relates to the technical field of underwater power equipment, in particular to an obliquely and symmetrically distributed underwater propeller which adopts a group of driving assemblies which are obliquely and symmetrically arranged based on the center line of a shell, and the horizontal deflection angles of the two driving assemblies are 8.5 degrees. Comprising a driving motor, a bearing, a bearing oil seal, a bearing seat, a rotating shaft, a rotating shaft oil seal, a gasket and propeller blades, when the water flow is disordered and a leftward or rightward water flow impact resultant force exists in a horizontal plane determined by a connecting line of the driving motors and the propeller blades, a resultant force which is equal to the current water flow impact resultant force in magnitude and opposite to the current water flow impact resultant force in direction is generated in the plane by changing the differential speed of the two driving motors; and the interference of the water flow impact resultant force on the underwater propeller is counteracted. According to the underwater propeller, the static and dynamic underwater stability of the underwater vehicle can be greatly improved, the good anti-interference capability is achieved, meanwhile, the structural arrangement is compact, and the size of the underwater vehicle can be greatly reduced.
本发明涉及水下动力装备技术领域,具体涉及一种斜向对称分布的水下推进器,其采用基于外壳的中心线倾斜对称设置的一组驱动组件,两驱动组件的水平偏转角度均为8.5°,包括驱动电机、轴承、轴承油封、轴承座、转轴、转轴油封、垫圈和螺旋桨桨叶;当水流紊乱,在由驱动电机、螺旋桨桨叶连线所确定的水平平面内,存在向左或向右的水流冲击合力时,通过改变两个驱动电机的差速,在该平面内,产生一与此时水流冲击合力大小相等、方向相反的合力,抵消该水流冲击合力给水下推进器带来的干扰。本发明的水下推进器可大大提升水下潜航器的静态、动态水下稳定性,具有良好的抗干扰能力,同时其结构布置紧凑,可大大减少水下潜航器的体积。
