Magnus effect rotor utilizing wind energy to generate electricity and produce pushing force

Abstract

The invention provides a Magnus effect rotor utilizing wind energy to generate electricity and produce pushing force. The Magnus effect rotor comprises a main rotating shaft, a main rotating barrel assembly, a plurality of sets of fan blade assemblies and a fan blade driving assembly. A plurality of fan blades evenly distributed around the circumference are installed inside a main rotating barrel, and due to the fact that fan blade folding and unfolding control driving gears are meshed with fan blade folding and unfolding control driven gears in a matched mode, a servo control motor can control all fan blades to stretch into or out of the main rotating barrel at the same time, wherein the fan blade folding and unfolding control driving gears are installed on a servo drive motor, and the fan blade folding and unfolding control driven gears are arranged on the end portions of all fan blade clamping sleeve rotating shafts. When the fan blades are located inside the main rotating barrel, the main rotating barrel is driven by an external motor to rotate, and then large pushing force is produced under the action of incoming flow. When the main rotating barrel is not needed to produce the pushing force, the fan blades stretch out of the main rotating barrel and are driven by wind power to drive the main rotating shaft to rotate so as to drive an external electric generator to generate electricity through the wind power. The rotor not only can serve as a propeller for providing the pushing force, but also can be used for generating the electricity when the pushing force does not need to be provided; the wind energy is fully utilized, and the Magnus effect rotor has high economical efficiency.

Description

technical field [0001] The invention belongs to the field of propulsion technology, in particular to a Magnus effect rotor that uses wind energy to generate electricity and generate thrust. Background technique [0002] The classic Magnus effect refers to a phenomenon in which a rotating cylinder moving in a viscous incompressible fluid is subjected to a lifting force. For example, when a soccer ball moves in the airflow, if the rotation direction of the upper spherical surface is in the same direction as the airflow, it will drive the airflow near the upper spherical surface to increase the flow velocity on the upper spherical surface and generate low pressure; The spherical surface creates high pressure, which creates lift. [0003] At present, the application of the Magnus effect is as the propulsion device of the ship and the rotor of wind power generation. [0004] Magnus effect rotors can be used as a propulsion system for ships due to strong offshore winds. Chinese...

Problems solved by technology

The disadvantage of this device is that each radial rotating cylinder used to drive the horizontal rotating shaft to rotate and generate electricity cannot actively rotate around the central axis of its own cylinder, and the Magnus force provided is very limited, and the power generation efficiency at low wind speed may not be as good as the conventional level shaft wind turbine

However, the current Magnus effect rotor is still used alone in propulsion devices or wind power generation devices, the utilization rate of wind energy is limited, and the characteristics of the Magnus effect have not been fully utilized to maximize its effectiveness
