[0002] AC variable frequency speed regulation refers to the technology of changing the number of pole pairs of the stator winding of the AC motor to achieve AC motor speed regulation. When the power supply frequency remains unchanged, the synchronous speed of the AC motor is inversely proportional to the number of pole pairs. Changing the number of winding pole pairs can change the speed of the motor.

[0003] At present, when the traditional lateral propulsion device is working, it is transmitted through the traditional transmission device. In this way, the rotation speed of the lateral propulsion device cannot be effectively adjusted. In this way, the rotation speed of the lateral propulsion device is relatively fixed and the effect of variable frequency speed regulation cannot be achieved.

[0004] In view of the above situation, we provide a lateral propulsion device capable of realizing AC variable frequency speed regulation. In this device, an AC variable frequency speed regulator is fixedly installed inside the hull, and a rotating shaft is installed at the output end of the AC variable frequency speed regulator, and a driving gear is installed at the bottom of the rotating shaft. The driving gear cooperates with the helical gear on the connecting shaft, and the AC variable frequency speed regulator adjusts the rotating speed of the driving gear to effectively adjust the rotating speed of the propeller; thereby effectively realizing the driving of the propulsion component by the AC variable frequency speed regulator.
