Abstract

The invention provides a marine propulsion system, and belongs to the technical field of marine propulsion. The marine propulsion system comprises a power battery, a generator set, a motor controller, a motor body, an engine, a gearbox and a propeller. A motor shaft is arranged at the output end of the motor body, a shell is arranged on the outer surface of the motor body, an air inlet hole is formed in one side of the shell, a dust removal and heat dissipation assembly is fixedly installed on the shell, and the dust removal and heat dissipation assembly comprises a filter screen, a first ventilation pipe, a second ventilation pipe, fan blades and an air supply cover. A guide piece is arranged at the end, close to the air inlet hole, of the first ventilation pipe, and the fan blades are arranged in the second ventilation pipe. According to the device, centrifugal operation is conducted on dust through the first ventilation pipe, the second ventilation pipe and the air supply cover, the dust is prevented from entering the shell and damaging the motor, meanwhile, power is provided through electric power and fuel power, and the phenomenon of insufficient power in the sailing process is reduced.

Description

technical field [0001] The present invention relates to the technical field of marine propulsion, in particular to a marine propulsion system. Background technique [0002] During the ship's navigation, the ship's power system is the most important technical part of the ship, consisting of the main engine, shafting, shafting accessories, transmission equipment and propellers. The mechanical propulsion system uses heat engines (diesel engines, steam turbines, gas turbines, etc.) as power to directly drive propellers. The most commonly used propeller propulsion device is the internal combustion engine mechanical propulsion system. [0003] However, with the rapid development of modern power electronic equipment and the propulsion requirements of special engineering ships, the electric propulsion method of the inverter controlling the motor to drive the propeller is more and more favored by the owners of engineering ships. Practice has fully proved that electric propulsion shi...
