Large commercial ship sail and multi-turbine power generation adaptive combined device

Abstract

The invention provides a large commercial ship sail and multi-turbine power generation adaptive combined device which is mounted on a bow deck of a large sailing commercial ship and can adapt to the change of the wind direction to realize intelligent switching between wind power generation and sail boosting during sailing of the ship. During wind power generation or sail boosting, the windward state of the device can be adjusted under the rotating action of the hydraulic motor, and maximum utilization of wind energy is achieved. According to the device, the multiple wind turbines are adopted for power generation, the effective recycling area of wind energy can be increased, and the power generation effect is improved. In addition, when the ship sails against the wind, the device can lie down towards the stern under the thrust action of the hydraulic oil cylinder, and extra sailing resistance cannot be generated. The fuel oil consumption of the ship can be reduced, energy conservation and emission reduction of the ship are achieved, and the good practical application value is achieved.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to an adaptive combination device for large-scale merchant ship sails and multi-turbine power generation. Background technique [0002] With the general improvement of ship pollution problems in the international scope, ship energy saving and emission reduction has become one of the hot spots in the current shipping industry research. Traditional large-scale merchant ships need to burn fuel oil to provide power, and the NO produced by burning fuel oil x , SO x and CO 2 Pollutants such as gas and PM2.5 have aggravated the burden on the environment. At present, the utilization of wind energy on ships is very popular, not only because wind energy is a clean and non-polluting renewable energy, but also because most of the seas where large commercial ships sail are empty and wind energy resources are very rich. The application of wind energy on ships can reduce the use of f...

Problems solved by technology

However, when sailing against the wind, large merchant ships cannot use zigzag sailing to achieve sail boosting. The reason is that large merchant ships have a large direct contact area with seawater due to their large size and total load, which causes the seawater to have a very large impact on the hull. The relatively small thrust of sail propulsion can only be used as auxiliary propulsion for ships, and cannot be used as the main source of propulsion for large ships. , but the length of the ship's route is greatly increased, and the fuel consumption increases accordingly. It will appear that the amount of fuel saved by using sail boosting is far less than the additional fuel consumption of the ship caused by the increase of the distance due to the change of the route. The gain outweighs the gain

Therefore, although sail propulsion can bring great benefits when large merchant ships sail downwind, it is not very feasible when sailing against the wind
