Description
Technical field:
The present invention relates to wind-driven generator, relate in particular to columnar multistage aerogenerator.
Background technique:
Convert wind energy to electric energy, promptly wind-powered electricity generation energy converting system has reached 1MW～1.5MW level in industrial application.The wind-driven generator of prior art relies on facilities such as high tower, Da Ye oar in specific wind energy turbine set, in the hope of obtaining high wind speed, thereby produce electric energy, and this is feasible the tuyere area of wind is arranged throughout the year.But have the area of wind forward limited after all, and high tower also can not be in the densely populated areas installation and operation, therefore, this is the civil nature that the wind power plant of feature is difficult to the technology that realizes with the high tower throughout the year.
Summary of the invention:
The objective of the invention is to, overcome the deficiencies in the prior art part, providing a kind of is a kind of columnar multistage aerogenerator, this is a kind of innovation that utilizes wind energy, this wind-driven generator has good wind-drive device, under supporting multistep speed regulation generator is supported, under wind speed 4.8Km/h condition, can produce electric energy in other words at force one wind.So in any position, any height all can install, and really realized the purpose of wind-powered electricity generation conversion civil nature.
Columnar multistage aerogenerator of the present invention, include wind-driven generator and vertical type leaf oar two large divisions and form, comprise specifically: frame, secondary leaf oar A, one-level leaf oar B, generator unit stator, generator amature, rectifier, charger, storage battery and inverter are formed.Said leaf oar comprises one-level leaf oar B and secondary leaf oar A, is two blades of its sectional area semicircular in shape shape, and mutual on the straight line on a plane, and hollow circle of middle formation adopts form uprightly is set, so also can be referred to as vertical type leaf oar.Every grade of leaf paddle structure is identical, and is 90 degree with center of circle straight line.Generator unit stator is made of a plurality of permanent magnets that discreteness distributes, and forms the classification cutting magnetic line movement automatically according to rotor speed; Number by control rotor and stator makes same typhoon power generator have the electricity generation efficiency of different brackets.The stator and the spacing between the rotor of generator can be regulated; By spacing manual or automated manner adjustment stator and rotor,, make it have the electricity generation efficiency of different brackets not changing under the wind-driven generator body framework situation.Generator is slow-revving double current generator, and can multistage adjusting rotating speed; Characteristics with " no iron core " coil of " break-through technique for coiling technology ".Its generator adopts the traction design, when wind speed makes rotor speed reach the micro computer preset control value, has the rotating speed restraining device, thereby the Control work load forms and prevents to damage function.Said vertical type leaf oar is the device that the present invention is used to obtain wind-force, includes frame, one-level leaf oar B and secondary leaf oar A and forms, and frame is the body supports part of vertical type leaf oar of the present invention, and integral body is the framework structure.Be provided with multistage leaf oar in frame, the leaf oar that said leaf oar is two semi-circle forms is the center of circle with the central point of frame alternately point-blank.On one-level leaf oar B, be provided with secondary leaf oar A, one-level leaf oar B and secondary leaf oar A are conglobate two blades of sectional area, mutual on the straight line on a plane, but be arranged on the secondary leaf oar A on the one-level leaf oar B two blades mutual straight line, should with two blades of one-level leaf oar B the mutual certain angle of straight line fork, maximum fork angle is 90 degree.That is to say that if said leaf oar only is provided with one-level leaf oar B and secondary leaf oar A is two-layer altogether, two-layer straight line fork angle is 90 degree; If the number of plies that is provided with is many more, the angle of the mutual straight line fork of two leaf oars is also just more little between each layer.The connection of leaf oar lower end is provided with generator amature, cooperates with generator unit stator, is arranged on the lower end of frame.Main feature of the present invention is, said leaf oar is conglobate two blades in its cross section, and mutual on the straight line of a disk, hollow circle of middle formation.Every grade is 90 with center of circle straight line and spends.Said leaf oar comprises one-level leaf oar B and secondary leaf oar A, is set to multilayer form, multilevel hierarchy, to increase the wind gathering area.The leaf oar is provided with the air draft groove of exponential curve horn shape, installs in frame.The leaf oar is realized collection wind under any wind direction.When wind entered the leaf oar, wind speed slowed down, and wind is given the leaf oar with energy transfer, and the leaf oar promotes turbo machine rotating shaft rotation to turbo machine rotating shaft acting, pushing generator rotor rotation just.Generator amature rotates in generator unit stator and has formed magnetic force line cutting, produces electric current.Rectifier carries out bridge rectifier, carries out electric energy by the charger accumulators and stores, and inverter is given the power supply of electricity consumption load.
Principle of the present invention: the leaf oar of wind-drive device is semi-circular, has reduced the back side that will return the leaf oar thus and has pushed the resistance of direction down with the wind to, and starting torque is reduced.Open circles in the middle of the leaf oar forms " stagnation pressure " after can making wind energy enter semicircle leaf oar, increases wind energy, reduces turbulent flow.Multilayer leaf oar is mutually 90 ° to be cut apart, and guiding leaf oar can adapt to various wind directions.Under this structure, thereby wind speed is slowed down the formation wind energy, and promotes turbo machine rotating shaft acting, realizes rotatablely moving.When the turbo machine rotating shaft is designed to generator amature, just in generator unit stator, do the motion of cutting magnetic line.Generator unit stator constitutes for the discreteness permanent magnet, realizes the requirement of multistep speed regulation, has reduced the wind speed requirement that produces electric energy.After generator produces electric energy,, electric energy is stored in the storage battery by built-in charger through rectifier rectification.During the electricity consumption loaded work piece, exchange or direct current output by inverter.
The said wind-driven generator of the present invention is arranged on one-level leaf oar B axis generator bottom, and generator amature connects bottom with one-level leaf oar B axis, and generator unit stator then is fixed on the bottom of frame.Said frame is the housing fender bracket of columnar multistage aerogenerator of the present invention, also is supporting frame.On four faces of said frame, all be provided with the wind shield that to regulate, when wind-force or wind speed surpass regulation numerical value, can suitably close the wind shield on the frame, reduce air output, just regulate the air quantity that blows on one-level leaf oar B and the secondary leaf oar A by wind shield.
Columnar multistage aerogenerator of the present invention, overall structure is simple, can adapt to the wind-power electricity generation under the multiple environmental conditions, especially can adapt to the wind-power electricity generation under the uncertain and less condition of wind-force of wind direction.Columnar multistage aerogenerator of the present invention is a packaged type, is convenient to move, and is easy to carry, and is convenient to install; Any position can be installed on, any height can be installed on.Under different wind friction velocities, carry out the multiple control of presetting by micro computer.Wind speed is that 4.8Km/h (beaufort wind scale light air) can begin generating; Wind speed is that 104Km/h (beaufort wind scale storm) also can generate electricity.
