Novel propelling system based on magnus effect

Abstract

The invention provides a novel propelling system based on a magnus effect. The novel propelling system comprises a magnus effect rotor and a task conversion control device, wherein the magnus effect rotor comprises a main rotating shaft, a main rotating drum assembly, a plurality of groups of fan blade assemblies and a fan blade drive assembly, and the task conversion control device comprises a box body, a main linear guide rail slide-block mechanism, an auxiliary linear guide rail slide-block mechanism, a slide-block pulling rod, a main rotating shaft drive mechanism and a power generating mechanism. The magnus effect rotor can be taken as a propelling rotor when thrust needs to be produced and can be switched to a power generation rotor when the thrust does not need to be produced or the wind direction is unfavorable, so that the utilization rate of wind energy is high; the task conversion control device adopts a simple hydraulic actuating manner, fast conversion of tasks for adopting the magnus effect rotor as the propeller or as the power generation rotor can be realized only through one hydraulic cylinder and two linear guide rails, the mechanism is simple, and the propelling system can be taken as a propeller for providing the pushing force or a power generator for storing energy.

Description

technical field [0001] The invention belongs to the field of propulsion technology, in particular to a novel propulsion system based on the Magnus effect. 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. The propulsion system designed according to the Magnus effect is the Magnus effect propulsion system. [0003] Magnus effect rotors can be used as a propulsion system for ships due to strong offshore winds. Chinese patent CN102803065A applied by J.P. Winkler et al. discloses a ship in...

AI Technical Summary

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

[0006] From the above, it can be seen that the current application of the Magnus effect is mainly as a propulsion rotor for ships and a rotor for wind power generation alone, and has not yet combined its propulsion function and power generation function to fully utilize wind energy resources.
