Problems solved by technology
The main problems are as follows: 1) The installation and arrangement of the battery modules are highly demanding. In addition to requiring a dedicated battery compartment, a series of issues such as ventilation and heat dissipation must also be considered
2) The weight of the battery is heavy, and the layout is concentrated, which requires high stability of the center of gravity of the whole ship; 3) The lithium battery has certain safety hazards, and thermal runaway will occur in the case of impact, internal short circuit, etc.
4) Environmental pollution caused by waste lithium batteries cannot be solved at present
5) It is difficult to charge / replace batteries powered by large-capacity lithium batteries
6) At present, the shipment of lithium batteries is limited by the installation space and ship weight control, and the voyage is short
7) Lithium battery life is short, generally about 5-6 years, the entire ship cycle needs to be replaced many times, and the cost is high

Embodiment
[0033] This example takes a 5,000-ton cargo ship as an example. See figure 1 , the bottom of the original ship is equipped with a fixed ballast tank with a capacity of about 500 cubic meters. A total of 7 pairs of bottom ballast tanks are arranged symmetrically. It is now changed to an electro-hydraulic tank, of which the 7 ballast tanks on the port side are used to store the positive electro-hydraulic, and the 7 ballast tanks on the starboard side are used to store the negative electro-hydraulic. The left and right positive and negative electro-hydraulic compartments are isolated from each other.
[0034] For a schematic diagram of the vanadium redox flow battery’s electro-hydraulic supply and external piping system, see image 3 , the positive / negative electrode electro-hydraulic tank and the inside of the stack are connected through a piping system, and driven by the electro-hydraulic circulation pump, the electro-hydraulic completes the internal cycle of the electro-hydr...

The invention discloses a ship overall design scheme based on vanadium redox flow battery power, a vanadium redox flow battery is adopted as a main power source, a special electro-hydraulic cabin is arranged at the bottom of a ship body, battery electro-hydraulic is placed, the ship serves as ship self-fixed ballast, and the installed capacity of the battery is larger than that of a common lithiumbattery. On the premise that the weight of the ship is not increased or slightly increased, the problem that a large-capacity battery gets on the ship is solved, and the endurance mileage of the shipis greatly increased. In addition, an electro-hydraulic tank is arranged and provided with an output pipe system and a special output pump and used for conducting electro-hydraulic replacement with the shore. And the charging and battery replacing difficulties of the conventional lithium battery ship are effectively solved. The problems that a conventional lithium battery power ship is low in safety, short in battery service life, large in waste lithium battery pollution, limited in lithium battery shipment capacity, difficult to charge and replace and the like are effectively solved.
Description
technical field [0001] The invention relates to a ship overall design scheme based on vanadium redox flow battery power, and belongs to the technical field of ship design and construction. Background technique [0002] At present, the vast majority of conventional battery-powered ships use lithium iron phosphate batteries or ternary lithium batteries. The main problems are as follows: 1) The installation and layout of the battery modules are highly demanding. In addition to requiring a dedicated battery compartment, a series of issues such as ventilation and heat dissipation must also be considered. 2) The weight of the battery is heavy, and the layout is concentrated, which requires high stability of the center of gravity of the whole ship; 3) Lithium batteries have certain safety hazards, and thermal runaway will occur under conditions such as impact and internal short circuit. 4) The environmental pollution caused by waste lithium batteries cannot be solved at present. ...
