The invention discloses a contra-rotating double-paddle underwater thruster in the technical field of underwater thrusters, which comprises a thruster shell, the outer surface of the thruster shell is fixedly connected with a spoiler through a bracket, the inner surface of the thruster shell is fixedly connected with a mounting shell through a connecting rod, and a first stepping motor is fixed on the left wall of an inner cavity of the mounting shell; a second stepping motor is fixed to the right wall of the inner cavity of the mounting shell, a first angle sensor is mounted on the first stepping motor, and a second angle sensor is mounted on the second stepping motor; the two driving motors are respectively provided with a high-precision angle position sensor, and a special motor control method is adopted to enable the first paddle and the second paddle to synchronously and reversely rotate, so that the purpose of contra-rotating propulsion is achieved under the condition that a transmission mechanism is not used; and meanwhile, a single paddle can be selected to rotate according to actual requirements.

    本发明公开了水下推进器技术领域的一种对转双桨水下推进器,包括包括推进器壳体,所述推进器壳体外表面通过支架固定连接有扰流板,所述推进器壳体内表面通过连杆固定连接有安装壳,所述安装壳内腔左壁固定有第一步进电机,所述安装壳内腔右壁固定有第二步进电机,所述第一步进电机上安装有第一角度传感器,所述第二步进电机上安装有第二角度传感器;本发明通过将两个驱动电机分别配置有高精度角度位置传感器,采用特殊的电机控制方法使得第一桨叶与第二桨叶同步反向旋转,从而在不使用传动机构的情况下达到对转推进的目的,同时能够根据实际需要选择单个桨叶进行旋转工作。
