Device and method for comprehensively utilizing wind energy on commercial ship

Abstract

The invention provides a device and method for comprehensively utilizing wind energy on a commercial ship, and the device comprises a rotating column A, a rotating column B, a rotating column C, a rotating column D, a rotating column E, a rotating column F, a rotating column G, a rotating column H, a base, a deformable sail, a platform, a platform support column and a rail. According to the invention, the eight rotating columns are surrounded by the deformable sail, so that the rotary drum sail with a larger size and an approximately circular cross section is formed; Compared with a traditional Magnus rotary drum sail, the deformable sail has the advantages that the thrust generated in unit mass is large, and the utilization rate of wind energy is high. Besides, the deformable sail can deform according to different wind directions; the windward area of the deformable sail can be reduced during windward sailing of the ship, and the problem of large wind resistance of a traditional rotary drum sail during windward sailing is solved; and the diameter of the deformable sail is close to 2 / 3 of the width of the ship when wind comes from a port or a starboard of the ship, so that large Magnus thrust can be generated, ship oil consumption is reduced, and ship energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of ships, and in particular relates to a device and method for comprehensively utilizing wind energy on merchant ships. Background technique [0002] With the development of trade globalization, the trade of goods among countries in the world has become more and more frequent. The goods transported between countries, especially bulk goods or bulk goods, are mostly transported by ships, but ships not only consume a lot of and the waste gas emitted by burning fuel oil will pollute the environment, so finding new alternative energy sources and energy saving and emission reduction has become an urgent problem to be solved for ships. [0003] In recent years, some researchers and scholars have installed wind energy devices on sailing merchant ships to convert wind energy into the propulsion of ship navigation, reduce the fuel consumption of ships, and realize the energy saving and emission reduction of ships.

AI Technical Summary

Problems solved by technology

Although there are many similar patent solutions, there are the following common problems: first, when the ship is sailing against the wind, due to the existence of the rotary sail, it will bring a large additional wind resistance to the ship's navigation and increase the fuel consumption of the ship; Rotor sails need to be installed on the ship deck, so considering the limitations of deck space, ship stability, rotor height and other factors, usually the size of the rotor sail is small, the diameter cannot be too large, and the height cannot be too high. During the process, when the wind comes from the port side or the starboard side, the wind receiving area is smaller, resulting in a smaller Magnus effect along the direction of the ship’s navigation.
