Problems solved by technology

[0002] Ship electric propulsion refers to a propulsion method that uses electric motors to drive propellers to propel ships. The general ship electric propulsion device is a single propeller propulsion structure. This structure has low transmission efficiency and weak wind resistance. Once the propeller is damaged, the ship will not be able to Navigation, poor risk resistance
[0003] The structure of the existing ship electric propulsion device is relatively complicated, and the installation and disassembly of the propeller is inconvenient; in addition, the current ship electric propulsion device consumes a lot of power, the energy utilization rate is not high enough, and it lacks the corresponding emergency power supply, so it is difficult to deal with emergencies

Abstract

The invention discloses an electric propulsion device for a ship. The device comprises a driving motor and a generator, an output shaft of the driving motor is connected with the input end of a speedreducer; the output end of the speed reducer is fixedly connected with a first rotating shaft, the right end of the first rotating shaft is connected with a driving gear, the front portion and the rear portion of the driving gear are each connected with a driven gear in an engaged mode, the right end face of each driven gear is connected with a second rotating shaft, and the second rotating shaftsare in threaded connection with shaft rods; an output shaft of the generator is connected with a driven belt wheel, and a first driving belt wheel and a second driving belt wheel are both connected with the driven belt wheel through belts. The device comprises the two propellers, and is high in sailing speed and high in wind resistance; through the arrangement of the driving gear, the driven gears and the generator, a part of mechanical energy can be converted into electric energy, the electric energy is stored in a storage battery, and the stored electric energy serves as an emergency powersupply.
