Abstract

The invention relates to a cargo ship and specifically relates to an electric propelled inland river cargo ship. The invention solves the problems of poor power property, inferior energy-saving and environment-friendly property, high noise and vibration, poor running economical efficiency and poor operation flexibility of the present inland river cargo ship. The electric propelled inland river cargo ship comprises a generating system, a power distribution system, a main propelling system and an auxiliary system, wherein the generating system comprises a plurality of constant-speed generator sets; the power distribution system comprises a main power distribution plate, an auxiliary power distribution plate, a main transformer, an auxiliary transformer, a plurality of refrigerated container transformers, an AC690V bus bar mounted on the main power distribution plate, an AC400V bus bar mounted on the auxiliary power distribution plate and an AC220V bus bar mounted on the auxiliary power distribution plate; and the main propelling system comprises two propelling frequency converters, two propelling motors, two gear boxes and two full-rotation propellers. The electric propelled inland river cargo ship is suitable for inland river transportation.

Description

technical field [0001] The invention relates to a transport ship, in particular to an electric propulsion inland river transport ship. Background technique [0002] The inland river transport ship is an important means of transportation for cargo transportation in inland rivers or coastal waters. It has the characteristics of large transportation volume, low energy consumption and good economy. Under the existing technical conditions, the structure of an inland water transport ship usually includes a main propulsion system and an auxiliary system. Among them, the main propulsion system generally adopts the mechanical propulsion method of diesel engine + gearbox + propeller, as follows: the diesel engine is used as the main engine, and the main engine drives the propeller to rotate through the gearbox to generate thrust, so as to push the inland water transport ship to complete forward, backward and braking. run. Auxiliary systems usually include refrigerated containers, st...
