Abstract

The invention provides a semi-submersible type platform dynamic positioning model testing propulsive device, which belongs to the field of sea engineering. The propulsive device comprises a full circle swinging realization mechanism and a main transmission mechanism, wherein shafting of the main transmission mechanism is arranged inside the full circle swinging realization mechanism; a first bearing and a second bearing are arranged on an inner spindle; a first straight gear is arranged on a stepper motor, and is engaged with a second straight gear; the second straight gear is arranged on the upper end of an outer spindle; the outer spindle is provided with a pod and a conduit, and is connected in an outer shaft housing through a first thrust bearing and a second thrust bearing; and a third bearing is arranged on the end of the pod close to the end of a propeller. The propulsive device simplifies the shafting by adopting the main transmission mechanism and the full circle swinging mechanism, reasonably utilizes space, and ensures flexibility of the device. On the basis of not affecting operation of the main transmission mechanism, the propulsive device can realize omnibearing turning and omnibearing propulsion in 360 degrees, and improve response speed of a dynamic positioning propulsive system.

Description

technical field [0001] The invention relates to a propulsion device in the technical field of offshore platform engineering, in particular to a propulsion device for a semi-submersible platform dynamic positioning model test. Background technique [0002] The dynamic positioning propulsion device of the semi-submersible platform is the actuator of the deep-sea dynamic positioning propulsion system, which receives the thrust command issued by the control system to generate thrust. Deep-sea dynamic positioning propulsion systems generally use azimuth thrusters, which can be divided into Z-type azimuth thrusters and L-type azimuth thrusters according to the difference in the transmission shaft system. The main feature is that it can realize 360° omnidirectional advance. For now, there are few domestic and foreign dynamic positioning model tests on semi-submersible platforms. The reason is largely due to the shafting design, motor arrangement and sealing of the propulsion devic...
