Technical field

The invention mainly relates to technical field of wind power generation, especially a kind of novel blade and its application method.

Background technique

Under the background that global energy crisis and environmental crisis are got worse, wind energy resources start by common concern.Wind It can be most one of business potential, most active renewable energy, using cleaning, cost is relatively low, takes endless.China's wind energy Resourceful, the wind energy that can be developed and used is vast in territory, and marine land can be built, and wind energy is clean energy resource, and environmental benefit is good, Renewable, never exhausted, the wind power plant capital construction period is short, and scaleable of installing runs the advantages such as low with maintenance cost.Wind Power power generation can be effectively relieved air pollution, water pollution and the whole world and become while providing stable power supply for economic growth Warm problem.Large-scale promotion wind-powered electricity generation can make positive contribution for energy-saving and emission-reduction.Wind-power electricity generation is greatly developed to be filled to wind-power electricity generation Standby manufacturing industry provides the wide market space and prospect.The principle of wind-power electricity generation at present is to drive air vane using wind-force Rotation, then promoted the speed of rotation by booster engine, to promote electrical power generators.According to current wind driven generator technology, Four meters of airflow velocity about per second can start to generate electricity.This kind of blower category axial flow blower, i.e. wind direction and shaft Direction it is parallel, since to determine that it haves the shortcomings that following inevitable for its design feature: 1, cost is high, and cost is big；2, pacify Dress is difficult, and transport is difficult, Maintenance Difficulty；3, low efficiency, hardly possible starting, structure is complicated；Since air blade is circled around wheel hub, therefore wind Leaf is identical in different location angular speed, but linear velocity is different, thus each point discontinuity equalization, under certain revolving speed, some ground Side is positive force, and some places are opposite force, lead to inefficiency, are also possible to that the wind wing is caused to fracture when wind speed is larger；4, it needs Want large stretch of place；5, birds are constituted and is endangered；6, dust storm influences equipment big；7, family uses limited.

Summary of the invention

The purpose of the present invention is being directed to above-described problems of the prior art, provide a kind of novel blade and its Application method.

In order to realize the purpose, the present invention specifically adopts the following technical scheme that

A kind of novel blade, including upright bar 1, big blade 2, swivel becket 3, it is characterised in that: the swivel becket 3 is actively set on In upright bar 1, the big blade 2 has several, and even circumferential branch is arranged on swivel becket 3, and the big blade 2 is by upper and lower two Fan blade frame 21 and several rotatable vanelets 22 being mounted between upper and lower two fan blade frames 21 form, the fan blade frame 21 It is fixed on swivel becket 3, the underside of swivel becket 3 is provided with eccentric wheel 4 in the upright bar 1, in upright bar 1 under eccentric wheel 4 Side is fixed with fixed ring gear 5, is vertically and fixedly provided with wind direction board 6 on the eccentric wheel 4.

The vanelets 22 are connect by connecting rod 23 with the push rod 24 for being located at downside 21 side of fan blade frame, the push rod 24 1 End is connected with push-rod wheel 26, the central axes of the push-rod wheel 26 and the axis parallel of eccentric wheel 4, push rod by push the spring 25 Wheel 26 is close together under the action of push the spring 25 with 4 edge of eccentric wheel.

23 one end activity of connecting rod be inserted in vanelets 22 it is following on, 23 other end activity of connecting rod is inserted on push rod 24.

24 activity of push rod, which is located at, to be arranged in the fixing groove 27 on 21 side wall of fan blade frame.

Fixing groove 27 at 22 external end head of fan blade frame be " [", remaining is L shape.

Horizontal on the wind direction board 6 to be equipped with spring pin 6, the cone-shaped end level of the spring pin 6 is inserted in fixed tooth In the tooth socket of ring 5.

Shaft is arranged on side elevationally outward for the vanelets 22, and the shaft upper and lower ends activity is inserted in two fan blades up and down On frame 21.

The wind direction board 6 is located under push-rod wheel 26.

A kind of application method of the novel blade are as follows: when wind direction board is vertical with the direction of wind, wind blows wind direction board, Wind direction board band movable eccentric wheel turns to that wind direction board is parallel with wind direction, on the tip and fixed ring gear of the spring pin on wind direction board Tooth socket occlusion, eccentric wheel is fixed, and when the wind-force on wind direction board, which reaches, is enough that spring pin is allowed to bounce, wind direction board drives eccentric Wheel is rotated to suitable position；Push-rod wheel is close together under the action of push rod spring with eccentric wheel, and can be around eccentric rotation Dynamic, when big blade is rotated around upright bar, push rod is also rotated with it, and the vanelets on that face big blade rotated with the wind are by push rod The vanelets on that face big blade for pushing and spelling knot together, and rotate against the wind are pushed by push rod to be separated from each other, and is formed Gap.

Compared with prior art, the beneficial effects of the present invention are: its be arranged big blade be made of several vanelets, Vanelets can under the action of push rod with appropriate angle rotating folding, when fan blade frame is rotated around upright bar, rotate with the wind that Vanelets on the big blade of face spell knot and form integral planar shape together, increase wind-force, greatly increase generating efficiency, and inverse Vanelets on that face big blade of wind rotation are separated from each other, and form gap, reduce resistance.Specific beneficial effect has following several Point: 1, structure is simple, and manufacturing cost is cheap；2, installation and transportation are simple and convenient, and mounting height is low, generator can ground installation, dimension Shield is convenient, scaleable of installing；3, high-efficient, gentle breeze operation automatically controls；4, wind direction is not required, blade rotation space Small, wind loading rating is strong；5, site requirements is low；6, birds are not constituted with harm；7, because structure is simple, dust storm and other severe rings Border does not have an impact equipment；8, install scaleable, it is high-efficient, so household electricity demand can be met, winter can pair help confession Warm, electricity more than needed can also network.
