Wind power boosting rotor structure

Abstract

The invention relates to a wind power boosting rotor structure which comprises a base, an inner cylinder is fixedly mounted on the base, a plurality of basic rotating cylinders are axially mounted on the base on the outer side of the inner cylinder in a stacked manner, and the basic rotating cylinders are concentrically arranged outside the inner cylinder in a sleeving manner; partition plates are installed on the outer portion, located between the adjacent basic rotating cylinders, of the inner cylinder in the circumferential direction, and each single basic rotating cylinder independently rotates relative to the partition plate making contact with the basic rotating cylinder. The top of the uppermost basic rotating cylinder is provided with the same partition plate, and a top rotating cylinder is rotationally mounted above the partition plate; the inner cylinder is accommodated in the basic rotating cylinders and the top rotating cylinder; an end plate is arranged at the top end of the top rotating cylinder, and the bottom surface of the end plate is in arc transition connection with the top rotating cylinder body; The rotor is constructed in a modular mode, a large-diameter end plate can be configured, the overall height can be flexibly adjusted, the adaptability is good when wind speeds at different heights change, the lift and resistance generated by the rotor are effectively increased, the rotation torque of the rotor is reduced, and the aerodynamic efficiency of rotor rotation is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a wind boosting rotor structure. Background technique [0002] Innovative energy-saving technologies such as wind boost have gradually attracted extensive attention from ship owners and ship designers, especially wind boost rotors, which are developing very rapidly. [0003] The working principle of the wind-assisted rotor is the Magnus effect (Magnus effect), that is, the rotating cylinder will be subjected to a lateral force perpendicular to the direction of motion under the action of incoming flow. When a ship equipped with a wind boosting rotor is in a crosswind or oblique wind state, by adjusting the rotation direction of the rotor, the ship can generate thrust in the forward direction, thereby achieving the boosting effect. Compared with wind-assisted technologies such as kites and sails, the wind-assisted rotor has strong adaptability to wind speed and direction, a...
