Detailed description of the invention
The present invention relates to a kind of efficient wind wheel apparatus, including rotating shaft 1 and be distributed in rotating shaft 1 excircle
On vane group, described rotating shaft 1 is outside has additional circular support, and circular support includes the rotation at middle part
Pivoted housing 2, outside annulus 3 and connecting rod 4 between the two, rotary sleeve 2 is fixing with rotating shaft 1 suit,
Vane group include being positioned at circular support internal and centered by rotary sleeve 2 one group of blade of circular array
5, blade 5 is not more than the carbon fibre composite plate of 3mm for thickness, and blade 5 outer end is additionally provided with tune
The vane change device of joint blade 5 angle of attack, vane change device is fixed on annulus 3, described blade 5 two ends
It is respectively the blade tip 501 being connected with vane change device and the blade root 502 being connected with rotary sleeve 2, blade root
502 with annulus 3 residing for plane perpendicular, blade tip 501 to blade root 502 be by vane change device reverse
0-90 degree spiral-shaped.
Embodiment 1, as shown in Figure 1 to Figure 3, described blade 5 thickness is 1mm, and this thickness is being protected
On the premise of card blade 5 can be twisted, ensure that blade 5 is not easily broken in use or damages, again
The overall weight of wind wheel apparatus can be reduced to greatest extent, it is to avoid weight excessively increase the rotation caused
Turning frictional force to increase, vane change device includes fixed support 601 and servomotor 602, fixed support 601
Being fixed on annulus 3, it is internal that servomotor 602 is fixed on fixed support 601, servomotor 602
Clutch end and blade tip 502 outer end fixing be connected, the annulus 3 in circular support is for be arrangeding in parallel
Two, by connecting the two-wheel edge that is fixed as one of post, consolidating of vane change device between two annulus 3
Fixed rack 601 is fixed on two-wheel edge, and stationary state is more firm, and blade tip 501 is positioned at annulus 3
Same plane or parallel, is inverse paddle state, and plane residing for blade root 502 and annulus 3 is perpendicular, i.e.
For full feathering state, when wind-force is gradually increased, wind through the gap blade root 502, blade root 502
Can play certain ventilation and air inducing effect, meanwhile, wind-force blows on blade tip 501 end face, becomes oar
The wind-force size that servomotor 602 in device collects according to air pressure induction apparatus 702 is to blade tip
The anglec of rotation be adjusted, when wind-force is less than minimum setting value, controller 701 is believed according to wind-force
Breath sends dependent instruction to servomotor 602, and blade tip 501 is rotated to inverse paddle by servomotor 602
State, when wind-force exceedes minimum setting value and becomes larger, servomotor 602 drives blade tip 501 turns
Move and its angle of attack be gradually reduced, to avoid the damage of the excessive wind wheel apparatus caused of wind-force, spiral type
The blade 5 of shape forms a pocketed being easy to catch wind-force, and the ability that blade 5 catches wind is more existing
Blade is greatly improved, and the rotating speed of whole wind wheel apparatus is improved the most therewith, in the case of same wind-force,
The wind-power electricity generation conversion ratio of this wind wheel apparatus is higher.
Vane change device in the present invention is the automatic vane change device of intelligence, it is possible to adapt to different wind directions,
Make the wind wheel apparatus direction of rotation when different wind direction work identical, two air pressure induction apparatuss 702
Lay respectively at circular support both sides, air pressure induction apparatus 702 signal output part and controller 701
Signal input part is connected, and the signal output part of controller 701 is connected with servomotor 602, and wind wheel fills
Putting when initial wind direction works, the air pressure induction apparatus 702 of this wind direction correspondence side gathers wind direction letter
Breath, and send wind direction information to controller 701, controller 701 sends to servomotor 602 and runs
Instruction, servomotor 602 starts, and blade 5 gradually rotates under wind-force effect, and blade tip 501 rotates
After gradually form the pocketed in direction windward, catch wind-force and also drive wind wheel apparatus to rotate, wind-force the most at last
The mechanical energy of traction is converted to electric energy；When wind direction becomes rightabout, the air pressure of opposite side
Induction apparatus 702 gathers wind direction information and sends to controller 701, and controller 701 is to servomotor 602
Sending operational order, servomotor 602 inverts and drives blade tip 501 to revolve turnback, now, and leaf
The spiral-shaped pocketed for corresponding wind direction of sheet 5, catches wind-force and then drives wind wheel apparatus to rotate,
The rotation direction of wind wheel apparatus is constant, provides for the conversion process that follow-up changes mechanical energy is electric energy
Convenient, relevant electric energy converting equipment is without the conversion of travel direction, and all energy under different wind directions
Enough carry out electric energy conversion work.
Embodiment 2, as shown in Figure 4, in order to again increase the rotary speed of wind wheel apparatus, by circle
Support is set to the double-decker of concentric circles, is provided with vane group, thus may be used in each layer
To increase the quantity of blade 5, increase blade 5 and catch the total amount of wind energy, the rotary speed of wind wheel apparatus
Improving further, wind energy transformation rate is greatly improved, and the generating efficiency of this wind wheel apparatus improves therewith.
The wind wheel apparatus that the present invention relates to is also associated with remote server, the controller 701 of wind wheel apparatus
Its working status parameter can be fed back to remote server, including turning to, rotating speed, blade 5 angle of attack
Etc. parameter, operator can carry out the start and stop of wind wheel apparatus, each blade 5 by remote server
The angle of attack and the regulation of wind speed round, break down or operator's inconvenience enters existing at wind wheel apparatus
Under the maintenance state of field, the regulation of each wind wheel apparatus can be carried out easily.
Three oar blade type wind wheels are improved to vane type wind wheel, the quantity of blade 5 and area coverage by the present invention
All big than blade, it is possible to utilize more wind energy thus increase the torsional forces of wind wheel apparatus, blade root 502
Full feathering state wind can be made to pass through, make the more wind ventilating surface to wind wheel apparatus, blade 5
The twisted shapes of blade tip 501 to blade root 502 can form pocketed, and blade 5 is notable to the seizure amount of wind
Improving, faster, the wind energy utilization of wind wheel apparatus is greatly improved the rotary speed of wind wheel apparatus, blade 5
In blade tip 501 can combine wind energy and by controller by the servomotor 602 in vane change device
701 and the control of air pressure induction apparatus 702 carry out the regulation of blade 5 angle of attack, the varying strength of wind-force
The different angles of attack of corresponding blade 5, realize the peak use rate of wind energy under varying strength state, regulation
Process participates in without artificial, and automaticity is high.
Existing SANYE oar is merely capable of utilizing about 1/10th of passed through wind energy, uses this wind wheel
Device, adds the contact area between wind-force and wind wheel, and the structure of blade can increase speed, and increases
Add torsional forces, in the case of existing wind-driven generator, use this wind wheel, change big speed increaser,
In the case of mild wind, it is possible to generate electricity, under same wind speed, it is possible to send higher than SANYE oar 5
Electric energy more than times, improves the efficiency of wind-power electricity generation, improves the utilization rate of wind energy, decrease fire
The carbon emission that power generating brings, contributes to the improvement of air quality, strengthens the dynamics of environmental conservation.
