Abstract

The invention relates to a tuna longline ship propelled by combination of diesel and electricity. A power device of the tuna longline ship comprises a main engine, a propelling motor, an anchor generating set, a first main generating set and a second main generating set, wherein the main engine is connected with a propeller through one output end of a propelling gearbox, the other output end of the propelling gearbox is connected with the propelling motor, and the propelling motor is respectively connected with the anchor generating set, the first main generating set and the second main generating set through frequency transducers. Compared with the prior art, the tuna longline ship propelled by combination of diesel and electricity adopts a combined mode of conventional diesel propulsion and low-speed electric propulsion. When the ship is in a fast navigating working condition, the main engine drives the propeller through speed reduction of the propelling gearbox, when the ship navigates at low speed, the main engine stops and is disconnected with the gearbox, power is supplied to the propelling motor through the anchor generating set, the propelling motor drives the propeller after speed reduction of the gearbox, the rotating speed of the propelling motor can be adjusted through the frequency transducers so as to adjust the navigational speed of the ship. Thus, fuel oil is greatly saved, and the ship navigates at a low speed and is convenient to operate.

Description

technical field [0001] The invention relates to a tuna longline fishing boat, in particular to a diesel-electric hybrid propelled tuna longline fishing boat suitable for bags. Background technique [0002] With the adjustment of the national pelagic fishery industry structure, the pelagic fishery has begun to transform from inshore fishery to oceanic fishery. Tuna is a warm-water migratory fish in the ocean. It is not polluted by the environment. The meat is tender and delicious, with high nutritional value. The market is extremely broad. As a nutritious and valuable aquatic product, tuna will or is filling our tables. The market prospects at home and abroad are very broad, and the tuna longline fishing boat is the key equipment of the pelagic fishery. [0003] The conventional propulsion method of the existing tuna longline fishing boat usually adopts the mode of the fixed-pitch propeller driven by the diesel engine and the mode of the adjustable-pitch propeller driven by...
