No-steering gear electric-machine directly-driven advancing electric ship

Abstract

The invention provides a no-actuator motor direct-drive propelling electric ship; the structure of the invention consists of a preposed electric auxiliary rudder and a rear propeller; the preposed auxiliary rudder consists of a hollow bracket, an auxiliary rudder motor and a screw propeller; the screw propeller is fixed at the shaft part of the auxiliary rudder motor; the lower end of the hollow bracket is fixed with the shell of the auxiliary rudder motor; the upper end of the hollow bracket is fixed on the upper part of an auxiliary rudder cylinder; the power wire of the auxiliary rudder motor passes through the hollow bracket and is connected with a controller which is arranged inside a cab; the rear propeller consists of a steering machine, a hollow shaft, a propeller motor and a screw propeller; the hollow shaft is arranged at the tail rudder part of the ship body by a shaft sleeve; the lower end of the hollow shaft is connected with the shell of the propeller motor shell; the upper end of the hollow shaft is connected with the steering machine; the power wire of the propeller motor passes through the hollow shaft and is connected with the ship-used generator or accumulator. Compared with the prior art, the no-actuator motor direct-drive propelling electric ship has the advantages of reasonable design, simple structure, improving power, saving energy source, increasing the space in the cabin, easy maintenance, and the like, thereby having extremely good generalization and usage values.

Description

technical field [0001] The invention relates to a marine equipment accessory, in particular to an electric boat directly driven by a steering gear motor. Background technique [0002] At present, the power to drive ships is mainly a diesel engine. The power of the diesel engine passes through the clutch, gearbox, transmission shaft, and then after two times of reversing, it is connected to the propeller propeller, and then connected to the front steering auxiliary rudder. The front steering auxiliary rudder is used Due to the adjustment of the bow, it is mainly used for the sideways berthing and offshore of the ship. The shortcomings of the above power system in the power transmission process are 1) 30%-35% of the power is wasted as heat in the process of mechanical wear , with the shortage of fossil fuel resources such as oil and coal, the increase in cost, and the pollution of the environment caused by burning fossil fuels, people began to pay attention to energy conservat...

[0002] At present, the power to drive ships is mainly a diesel engine. The power of the diesel engine passes through the clutch, gearbox, transmission shaft, and then after two times of reversing, it is connected to the propeller propeller, and then connected to the front steering auxiliary rudder. The front steering auxiliary rudder is used Due to the adjustment of the bow, it is mainly used for the sideways berthing and offshore of the ship. The shortcomings of the above power system in the power transmission process are 1) 30%-35% of the power is wasted as heat in the process of mechanical wear , with the shortage of fossil fuel resources such as oil and coal, the increase in cost, and the pollution of the environment caused by burning fossil fuels, people began to pay attention to energy conservation. So far, people have only considered improving the efficiency of engines and reducing fuel consumption. ; 2) the diesel engine drive mode of prior art is diesel engine, clutch, gearbox, transmission shaft and two commutators, and these equipment volume is big, weight is big, and occupies bigger space in engine room, and equipment is in operation process Not only does it generate huge noise, but it is also worn parts, requiring irregular maintenance and regular overhaul, which not only reduces the utilization rate of the ship, but also increases the use and operating costs

At present, there is no better and more effective way to improve and save energy in the ship drive system
