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
The invention belongs to Push Technology field, be specially a kind of Magnus effect rotor utilizing wind energy to carry out generating electricity and producing thrust.
Background technique
Classical Magnus effect refers to that the rotating cylindrical moved in viscous incompressible fluid is subject to a kind of phenomenon of lifting force.Such as, when football moves in the gas flow, if sense of rotation of sphere and air-flow in the same way, then can drive the air motion near sphere, make the flow velocity of sphere increase on it, produce low pressure; Otherwise the lower peripheral surface contrary with airspeed direction then can produce high pressure, thus produce lifting force.
The application of current Magnus effect has the rotor of advancing means as boats and ships and wind-power electricity generation.
Because Oversea wind is comparatively strong, Magnus effect rotor can be used as the propulsion system of boats and ships.The Chinese patent CN102803065A applied for by people such as JP Winklers discloses the boats and ships comprising load mode Magnus effect rotor.The project that this invention provides comprises hull and deck, and the cylindrical rotor be vertically installed on deck has the cylindrical wall that can rotate around self vertical center line, and has upper end plate.This rotor upper end plate when not operating is positioned near deck, and end plate is provided with movable edge section, and edge section extends from peripheral wall radially outwardly when rotor operates, and is retracted to the position near peripheral wall when rotor does not operate.The advantage of the program to make full use of Oversea wind, for boats and ships provide part thrust; Its limitation is, utilize the Cross Wind Force vertical with ship course, if and what produce when wind direction is identical with course is lateral force, be unprofitable to Ship Propeling, now this Magnus effect rotor can not play progradation, for hull, become impost, make the program have high requirement for wind direction; In addition, when the boats and ships lay day that pulls in shore can not make full use of wind energy power, above-mentioned deficiency reduces its Economy and practicability.
A kind of Magnus type wind power generator is disclosed by the rich Chinese patent CN1846056 waiting people to apply for of letter in village.The invention provides a kind of Magnus type wind power generator that all can generate electricity to high wind speed region from low wind speed region.This device has: the feathering axis transmitting running torque to power facility portion; The rotating cylindrical radially arranged from this feathering axis; And the drive motor driving each rotating cylindrical to rotate around the axle of these rotating cylindricals.Feathering axis is rotated, in order to drive power facility portion by the Magnus lift produced by the rotation of each rotating cylindrical and the interaction of wind-force.The outer surface of rotating cylindrical arranges air flow unit, for generation of air flowing, and Magnus lift is increased.The deficiency of this device is: in order to drive each radial rotating cylindrical of feathering axis rotary electrification can not initiatively around own cylindrical center axis thereof, the magnus force provided is very limited, and the generating efficiency when low wind speed may be not so good as conventional levels axis wind power generator.
The Chinese patent CN102661241A applied for by J Sai Feite discloses a kind of wind power hybrid rotor scheme, and it has crossing current rotor, guiding device and Magnus rotor.Crossing current rotor keeps in the mode rotated around spin axis and has multiple rotor blade axially stretched.Guiding device has case section, and it partly so surrounds crossing current rotor in the circumferential, and the wind namely by flowing into drives crossing current rotor.Magnus rotor arrangements is within crossing current rotor, and wherein, Magnus rotor axis stretches on the direction of spin axis.Magnus rotor has closed side face, and drives Magnus rotor by drive unit in the mode rotated around described Magnus rotor axis.In the program, Magnus effect only plays booster action in wind-power electricity generation.
In a word, in general, according to Magnus effect feature, Magnus effect has a wide range of applications potentiality in the industry in future and energy field, particularly under ocean and high altitude environment, because wind can not be blocked, wind-force is stablized, and wind energy resources enriches, Magnus effect has great application prospect.But current Magnus effect rotor is still and is applied to separately advancing means or wind generating unit, and wind energy utilization is limited, does not also make full use of the feature of Magnus effect, plays its usefulness to greatest extent.
