The invention relates to an underwater propelling device, which belongs to the technical field of underwater equipment and comprises a propeller, a speed reducer, a motor and a control circuit board which are connected in sequence, a first key groove is formed in the end, connected with the speed reducer, of the propeller, a speed reducer output shaft is arranged at one end of the speed reducer, and a first insertion key matched with the first key groove is arranged on the speed reducer output shaft. A motor output shaft of the motor is provided with a second insertion key, and the other end of the speed reducer is provided with a second key groove matched with the second insertion key; the control circuit board is electrically connected with the motor and controls the motor to operate safely and stably. The speed reducer and the motor are coaxially connected through the second insertion key and the second key groove, so that power transmission between the speed reducer and the motor is better. Safe and stable-speed operation of the motor is controlled through the control circuit board, so that the influence of underwater obstacles and different resistances on the underwater propelling device is avoided, and the underwater propelling device can safely operate underwater at a stable speed.

    本申请涉及一种水下推进装置,属于水下设备技术领域,包括依次连接的螺旋桨、减速器、电机以及控制电路板;螺旋桨与减速器连接的一端设置有第一键槽,减速器的一端设置减速器输出轴,减速器输出轴上设置有与第一键槽相适配的第一插键;电机的电机输出轴设置有第二插键,减速器的另一端设置有与第二插键相适配的第二键槽;控制电路板与电机电连接,通过控制电路板控制电机安全稳速运行。减速器和电机之间通过第二插键、第二键槽实现同轴连接,使得减速器和电机之间的动力传输更好。通过控制电路板控制电机的安全稳速运行,以避免水下障碍物以及不同阻力对水下推进装置的影响,使得水下推进装置能够安全、稳速地运行在水下。
