AI Technical Summary

Problems solved by technology

[0011] The cost of this method is relatively high, because two drive motors and their corresponding accessories are required, and it involves synchronous control of multiple motors. Compared with single motor control, the control is more difficult, and the maintenance intensity and maintenance cost are relatively high.

Embodiment Construction

[0031] Combine Figure 5 to Figure 8 Describe the pod-type ship electric direct drive propulsion device of the present invention, which mainly includes: pod shell 501, power supply cable 502, motor cable socket 503, motor shell 511, front propeller 505, rear propeller 506, and front propeller drive shaft 507, rear propeller drive shaft 508, pod sealing cover 509 and double-ring set bearing 510.

[0032] Such as Figure 5 As shown, the pod housing 501 and the pod sealing cover 509 form a closed space, the motor housing 504 is installed in this closed space, and the power supply cable 502 provides electrical energy from the ship body to the motor through the motor cable socket 503. The motor shell in the pod can choose to install heat sinks or adopt an integrated design of the motor shell and the pod shell. When the ship is propelled, the pod is placed in the water and the motor can be cooled by water.

[0033] The outer rotor 512 of the motor is a hollow rotating shaft, and the...

Abstract

The invention discloses a podded ship electric-power direct-drive propelling device. A drive mechanism of the propelling device comprises a motor shell, a hollow outer rotor, a hollow stator, an inner rotor, an outer rotor transmission shaft and a two-ring nesting bearing, wherein the hollow outer rotor is arranged in the motor shell, the hollow stator is arranged inside the outer rotor, the inner rotor is arranged inside the stator, the outer rotor transmission shaft is fixedly connected with the outer rotor and a front propeller transmission shaft, and the two-ring nesting bearing is used for fixing the positions of the inner rotor and the outer rotor; a first winding for controlling the rotation of the inner rotor is arranged on the inner side of the stator, and a second winding for controlling the rotation of the outer rotor is arranged on the outer side of the stator. Based on a multiphase motor, the podded counter-rotation propeller propelling driven by two rotors can be realized, on the basis of inheriting all advantages of the multiphase motor and a two-rotor drive system, the efficiency of the device is higher, the power, rotation speed and rotation direction of a propeller can be spontaneously adjusted, the podded ship electric-power direct-drive propelling device is applicable to the existing ship electric power system platform, and the malfunction rate is lower.

Description

Technical field [0001] The invention relates to ship propulsion technology, in particular to a pod-type ship electric direct drive propulsion device, a propulsion system and a propulsion method. Background technique [0002] The pod-type counter-rotating propeller ship propeller is a new type of ship propulsion device that integrates propulsion and steering. The device can be installed at any position outside the hull, directly driving the propeller to rotate, and rotate horizontally within 360o to realize the vector propulsion of the ship. A counter-rotating propeller means that one propeller is arranged on the front and rear of the propeller. The diameter of the front propeller is larger than the diameter of the rear propeller, and the rotation direction of the two propellers is opposite. In the counter-rotating propeller propulsion system, the vortex energy generated by the front propeller can be effectively used in the rear propeller. [0003] Combine Figure 1a to Figure 3 De...
