Problems solved by technology

Ships are usually powered by diesel engines. When the diesel engine is damaged, the ship will lose its power and cannot continue its voyage
When navigating in areas where the water surface is icy, if the power of the diesel engine is insufficient, it will affect the speed of the ship, which has disadvantages

Abstract

The invention relates to a marine ship power system. The marine ship power system comprises a diesel engine, a motor, a gearbox and a propeller, wherein the gearbox comprises a first input shaft, a second input shaft, a multi-stage intermediate shaft and an output shaft; the first input shaft and the output shaft are arranged coaxially; the first input shaft and the output shaft are connected through a clutch; the second input shaft and the output shaft are driven through a multi-stage gear pair; the first input shaft is connected with the output end of the diesel engine; the input end of the second input shaft is connected with the motor; the output shaft is connected with the propeller; the motor is connected with a main distribution board through a frequency converter; the motor is connected with the input end and the output end of the main distribution board at different time, and a connection state is switched through a contactor; the input end of the main distribution board is further connected with a main generator.

Description

technical field [0001] The invention relates to the field of ships, in particular to a power system for marine ships. Background technique [0002] With the widening range and area of ​​ocean-going ships, ocean-going ships need to adapt to increasingly complex sailing routes. The requirements for ship power are getting higher and higher. Ships are usually powered by diesel engines. When the diesel engine is damaged, the ship will lose its power and cannot continue its voyage. When navigating in areas where the water surface is frozen, if the power of the diesel engine is insufficient, it will affect the speed of the ship, which has disadvantages. Contents of the invention [0003] The object of the present invention is to provide a power system for a marine vessel driven by dual power. [0004] The technical scheme that the present invention takes is: [0005] A marine ship power system includes a diesel engine, a motor, a gearbox and a propeller, the gearbox include...
