Description
Technical Field
The invention relates to the technical field of ship equipment, in particular to a ship superstructure arrangement structure matched with a wind power boosting rotor.
Background
Innovative energy-saving technologies such as wind power boosting and the like have recently attracted extensive attention from shipowners and ship designers. Especially, the wind power boosting rotor is developed rapidly. The principle of wind power-assisted rotor operation is the Magnus effect (Magnus effect), i.e. the rotating cylinder will be acted on by a lateral force perpendicular to the direction of motion under the action of the incoming flow. When the ship with the wind power boosting rotor is in a crosswind or inclined wind state, the rotating direction of the rotor is adjusted to enable the ship to generate thrust in the advancing direction, and therefore the boosting effect is achieved. Compared with wind power boosting technologies such as kites and sails, the wind power boosting rotor has strong adaptability to wind speed and wind direction, is relatively small in size and wind area, is safer and is more favorable for ship arrangement. In addition, wind power boosting rotors and hydrodynamic power energy-saving and emission-reducing means such as fuel substitution and the like can be used in a superposition mode, energy is saved, emission is reduced, and EEDI (external energy supply) of ships is reduced. The wind power boosting rotor of the ship is suitable for new ship building or operation, and has small investment and short recovery period for shipowners.
The wind power boosting rotor is used as an important innovative energy-saving device for the ship, and the wind power is utilized to reduce the fuel consumption of the ship and reduce the carbon emission of the ship. However, two important challenges are faced when actually using wind-assisted rotor technology. Firstly, in order to improve the utilization efficiency of wind energy, the rotor of the rotor is often made as high as possible, and the height of the rotor is close to or even exceeds the height of the cockpit, so that the sight of the cockpit is easily influenced when the rotor is arranged on a deck. And the size and arrangement of the rotor have to be limited in order to meet the specification requirements. Secondly, the additional thrust provided by the wind-assisted rotor is closely related to the wind direction, but the offshore wind direction is not controlled manually, which limits the energy-saving effect of the rotor.
