Abstract

The application discloses a full-revolution propeller base support structure for a ship and an assembling method thereof, and belongs to the technical field of shipbuilding. The base support structure comprises a support frame, a support elbow plate, a watertight sleeve, a false rudder and a simulated mounting ring, and the simulated mounting ring can be sleeved and fixed on the cylinder. The base support structure has the advantages of small quantity of parts, small design workload, ensured longitudinal continuity and transverse continuity of the structure, ensured strength and support rigidity of the whole structure, protected propeller connecting portions and played a flow guiding role through the false rudder structure, ensured the watertightness of the whole structure through the watertight sleeve structure, simulated positioning of the full-revolution propeller mounting position through the design of the simulated mounting ring, ensured the assembling method to be simple and convenient and ensured the mounting precision of the propeller, and can be suitable for various types of full-revolution propellers through the adjustment of the curvature of the first cutout of the support elbow plate, and has good applicability.
