Embodiment

[0019] See attached Figure 1-3 As shown, a rim propulsion system based on an integrated rudder system includes a slewing support 1 on which two rudder steering motors 2 are arranged to drive the rotating disc on the slewing support 1 to rotate. The output shaft of the steering motor 2 is fixed with a driving wheel, and the rotating disk is provided with a driven wheel that can mesh with the driving wheel, and the driven wheel is positioned between the two driving wheels. The steering motor 2 is connected with the steering gear inverter 3, and the rotation speed and direction of the steering gear motor 2 are controlled through the steering gear inverter 3. The model of the steering gear inverter 3 is MD500T11GB. The fixed plate of the slewing support 1 is fixed with a rudder angle feedback device 4 for displaying the steering angle. The rudder angle feedback device 4 can detect the actual rotation angle of the rotating disk, that is, the actual rudder angle. The model of the r...

Abstract

The invention discloses a rim propulsion system based on an integrated steering system, the rim propulsion system comprises a rotary support, two steering motors for driving a rotary disc on the rotary support to rotate are arranged on the rotary support, the steering motors are connected with a steering engine frequency converter, and a rudder angle feedback device for displaying a rudder angle is fixed on a fixed disc of the rotary support. An annular electric pusher is fixed to a rotating disc of the rotary support, the annular electric pusher is connected with a main pushing frequency converter, the rotating speed and direction of the annular electric pusher are controlled through the main pushing frequency converter, and a speed sensor for detecting the rotating speed of the annular electric pusher is arranged on the annular electric pusher. The rudder angle feedback device and the speed sensor are connected with the input end of the PLC, the output end of the PLC is connected with the main push frequency converter and the steering engine frequency converter, and the input end of the PLC is further connected with a handle which is located in a cab and used for controlling rudder turning. The propulsion system is compact in structure and can ensure the stability of ship operation.

Description

technical field [0001] The invention relates to the technical field of ship rim thruster control, in particular to a rim propulsion system based on an integrated steering system. Background technique [0002] Ship propeller refers to the energy converter in the ship propulsion device. It converts the power generated by the engine into the thrust of the ship to overcome the resistance of the ship navigating in the water and push the ship forward. The most common are propellers, but there are also paddle wheels, water jet propellers, jet propellers, ducted propellers, and rotary propellers. Shaftless rim thrusters have outstanding advantages in reducing shafting construction costs, increasing tank capacity, reducing vibration and noise, and have been widely used in recent years. The rim propeller realizes shaftless drive by means of electric current, which changes the propulsion mode of the traditional shaft drive propeller. Due to the large torque, low speed and high speed...
