Description

A kind of fan for wind-power electricity generation

Technical field

The utility model is related to a kind of field of wind power equipment, and in particular to a kind of fan for wind-power electricity generation.

Background technology

Wind-power electricity generation is that the kinetic energy kept watch is transformed into mechanical kinetic energy, then mechanical energy is converted into electric power kinetic energy.Wind-power electricity generation Principle, be to drive air vane to rotate using wind-force, then promote the speed of rotation by booster engine, to promote generator to send out Electricity.According to current windmill technology, three meters of gentle breeze speed about per second can start to generate electricity.Required for wind-power electricity generation Device, referred to as wind power generating set, this wind power generating set can generally divide wind wheel, generator and steel tower three parts.And Wind wheel is the important component that the kinetic energy kept watch is changed into mechanical energy, usually it by two or more propeller shapes impeller sets At when wind is to paddle, the rotation of pneumatic power drive wind wheel is generated on blade.

It is influenced since the rotating speed of wind wheel is often changed by the size and Orientation of wind-force, keeps wind speed round unstable, although The speed of rotation can be promoted to promote electrical power generators by booster engine, but increase kinetic energy, so wind-driven generator one As can only wind speed it is larger area could use, the less area of wind speed cannot generate electricity or cost of electricity-generating is excessively high, cause very much Area can not use wind-driven generator, popularization and application more to be limited to；Meanwhile under same wind conditions, the profit of wind energy Not high with rate, especially low wind speeds, major diameter impeller are difficult rotation, and wind power generating set is nearly at end-of-life state, causes Wind-power electricity generation investment is big, of high cost, income is small, seriously constrains the development of wind power generation industry.

Invention content

The utility model provides a kind of utilization rate that can increase with the contact surface of wind, raising wind energy, and is not limited by wind direction Wind-power electricity generation fan.

The technical solution of the utility model is a kind of fan for wind-power electricity generation thus, including flabellum, holder, special Sign is：The flabellum is made of interior flabellum and outer flabellum, and the centre of outer flabellum is in engraved structure, interior flabellum setting in The engraved structure in the centre of engraved structure, outer flabellum centre is consistent with the shape of interior flabellum, the outer wheels of interior flabellum Wide that gap is equipped between the engraved structure in outer flabellum centre, the flabellum stress surface of interior flabellum and outer flabellum is indent The flabellum stress surface of curved surface, interior flabellum and outer flabellum is oppositely arranged, formed in flabellum and the opposite structure of outer flabellum rotation direction；

The holder includes upper beam and bottom end rail, and the upper and lower end of outer flabellum is equipped with turn coaxial with outer flabellum center line Axis, outer flabellum are arranged by shaft between upper beam, bottom end rail, wherein the shaft bottom of outer flabellum upper end is equipped with counterbore, outside The shaft of flabellum lower end is in a tubular form；The upper and lower end of interior flabellum is equipped with the shaft coaxial with interior flabellum center line, interior flabellum upper end Shaft is inserted into the counterbore of outer flabellum upper end shaft, and the shaft of interior flabellum lower end penetrates the shaft of exterior wing hypophyll, on interior flabellum Between the shaft at end and the shaft counterbore of outer flabellum upper end, the shaft of interior flabellum lower end and the shaft of outer flabellum lower end match for gap It closes.

Preferably, the outer flabellum connects one group of generator by the shaft of the upper end, the shaft of interior flabellum lower end is worn The shaft for crossing outer flabellum lower end connects another group of generator.

Preferably, the interior flabellum is a piece of integrally formed blade, the cross section in width of blade direction is in serpentine； Outer flabellum is made of more blades, more blades uniformly diverging distribution centered on shaft.

The either ellipse or rectangular preferably, the interior flabellum assumes diamond in shape.

Preferably, the blade of the outer flabellum is three pieces.

Preferably, the outer flabellum is equipped with wind speed inductor and air quantity induction controller.

Preferably, the material of the outer flabellum and interior flabellum uses fiberglass or carbon fiber.

Preferably, being in series with multiple flabellums between the upper beam and bottom end rail.

Advantageous effect：

The utility model has reasonable design, simple in structure, easy to process, is not restricted by wind direction, can make full use of wind The characteristics of power resource, while the wind-power electricity generation area non-serviceable problem less in wind speed is overcome, thus, have good Popularizing value.

The flabellum stress surface of interior flabellum and outer flabellum is designed as the curved surface of indent and the flabellum stress of interior flabellum and outer flabellum Face is oppositely arranged, and this structure can be such that interior flabellum is rotated in opposite direction with outer flabellum, and interior flabellum drives a generating set, Outer flabellum drives a generating set, realizes that interior flabellum and outer flabellum generate electricity simultaneously.

The covering of the fan of interior flabellum uses a piece of integrally formed blade, easy to process, is not easily broken, and ensures service life, drop Low cost；Outer flabellum using three blades is considered based on cost, the balance of flabellum, efficiency, and using effect is best, simultaneously Wind from different directions can be concentrated water conservancy diversion to interior flabellum by three blades, adapt to different wind direction environment.

Using diamond shape, either ellipse or square structure, symmetry axis overlap interior flabellum with center line, flabellum stability of rotation, It is hardly damaged；Interior flabellum and outer flabellum are all made of the symmetrical structure of rule, and spin stabilization can generate the wind of uniform stabilization Source.

Wind speed inductor and air quantity induction controller are set, wind speed it is smaller, without departing from limit value in the case of, interior wing Leaf rotates power generation under the action of the forces of the wind, and outer flabellum does not start at this time, and flabellum in guiding of keeping watch makes interior flabellum than individual flabellum Contact more wind, rotating speed faster；When wind speed exceeds limit value, outer flabellum starts to reversely rotate under the action of the wind, makes coaxial Interior flabellum obtains the distinguished and admirable of superposition, and the covering of the fan outer rim linear velocity for making interior flabellum faster, improves the working efficiency of interior flabellum covering of the fan；Together When the rotation of interior flabellum formation the outer flabellum of distinguished and admirable drive blade, inside and outside flabellum mutually drives, and generates double drive superposition effect It answers.

Interior flabellum, outer flabellum material use fiberglass or carbon fiber, intensity high, light-weight.

Be in series with multiple flabellums between upper beam and bottom end rail, multiple flabellums can be installed on a holder, reduce at This, improves generating efficiency.
