Abstract

The invention relates to a fishing boat, in particular to an electric propulsion trawler, which solves the problems of poor power performance, poor energy conservation and environmental protection, large noise and vibration, poor operation economy and inconvenience in maintenance of the conventional trawler. The electric propulsion trawler comprises a power generation system, a power distribution system, a main propulsion system and an auxiliary system, wherein the power generation system comprises two constant speed power generation units; the power distribution system comprises an AC690V power distribution board, an AC400V power distribution board, a main transformer and an auxiliary transformer; the main propulsion system comprises two propulsion frequency converters, a double-armature alternating current propulsion motor, a gear box and a screw propeller; and the auxiliary material comprises deck machinery and auxiliary electric equipment. The electric propulsion trawler is applicable to various fishing operation.

Description

technical field [0001] The invention relates to a fishing boat, in particular to an electric propulsion fishing trawler. Background technique [0002] Trawlers are important operating tools for fishermen in coastal areas. When using a trawler for fishing operations, the trawler sails at a low speed on the water, collects the fishery goods into the fishing net through the tail trawl, and then automatically collects the net through the winch on the deck, and finally loads the fishery goods into the fish hold. Trawlers account for a large proportion of fishing boats because of their high operating efficiency and wide application range. Under existing technical conditions, the structure of a fishing trawler 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 ...
