An oil-electric self-hybrid propulsion system applied to inland waterway transport ships

Abstract

The invention discloses a petrol-electric self-hybrid power propelling system applied to inland water transport ships. Storage batteries are connected with a controller through a power manager, the controller is connected with a wheel house control console and a driver connected with a motor, and a first belt wheel is arranged on the shaft of the motor. The controller is connected with a diesel accelerator servo motor driver connected with a diesel accelerator servo motor, a second belt wheel is arranged on a main diesel through a gearbox, and the first belt wheel is in linkage with the second belt wheel through a cog belt. The cog belt is in linkage with the shaft of the motor through the first belt wheel and is in linkage with a universal coupling through the second belt wheel, and the universal coupling is in linage with an input end of a ship propeller. In a normal state, the storage batteries output electric energy through the motor to drive the ship propeller. The main diesel and the motor drive the ship propeller jointly when the storage batteries cannot meet the requirement of the headway of the ships. When the storage batteries lack electric power, the main diesel provides power for the ship propeller after starting, and the motor serves as a power generator to charge the storage batteries.

Description

technical field [0001] The invention belongs to the technical field of ship power systems, and in particular relates to an oil-electric self-hybrid propulsion system applied to inland water transport ships. Background technique [0002] The transportation industry is one of the key areas of energy consumption and emissions, and ships, as the means of transport with the largest proportion of carrying capacity in transportation, have a great impact on the national economy due to their energy-saving effect. Energy conservation and emission reduction has become an important topic of research in the shipbuilding and shipping circles of all countries in the world. It is related to issues such as saving fuel resources and costs, reducing exhaust emissions, environmental protection, and economic benefits of ship operations. The development of a low-carbon economy is also the realization of transportation. An important way to change the development mode. [0003] In 2011, the Marine...

Problems solved by technology

[0007] 2. Limited by the draft, the efficiency of the propeller is low

[0008] The branch lines of many inland waterways are still below Class 5. The water depth is shallow, weeds are overgrown underwater, and river silt is accumulated. Recently, in order to avoid friction between the propeller and the embankment, coupled with the influence of draft restrictions, the diameter of the propeller of the inland waterway ship is generally small, resulting in low propulsion efficiency

[0009] 3. The waterway passes through cities or scenic tourist areas, causing serious environmental pollution

At the same time, due to the large changes in the channel and the complex working conditions of the ship, it is difficult to match the performance of the hybrid electric propulsion system with the channel and ship conditions, and the research and development technology is difficult and costly

At present, domestic cases of actual installation and successful operation on ships are seldom reported, and the relevant design, development and application experience is insufficient. The technical parameters and indicators of energy saving and emission reduction have not been tested and determined by authoritative departments, so they are not convincing.

[0022] 2. The requirements for automatic operation are high, and the quality of the crew cannot keep up

Compared with the traditional mechanical propulsion bridge, the oil-electric self-hybrid propulsion system bridge has a higher degree of automation and intelligence, as well as a higher degree of automation of the monitoring program and computer operating system, and also puts forward higher requirements for the quality of the crew. It will take a long time for the operating system to be accepted and familiarized by the industry

[0024] 3. Compared with pure diesel engine or electric propulsion, the initial investment cost is relatively large

In addition, the maintenance, maintenance and management costs of the system will be increased in future operations, which will lead to higher ship construction costs than traditional mechanical propulsion systems. In addition, the traditional thinking mode believes that the main engine power of inland water transport ships is small, The speed is slow, and there is not much room for energy saving and emission reduction
