Among the figure: 1. column; 2. column bearing; 3. lower floor's wind wheel; 4. rotor bearing; 5. rotor; 6. upper strata wind wheel; 7. protective housing; 8. stator; 9. stator outer sleeve; 10. stress surface facings the wind; 11. lee face.
Embodiment
A kind of double-deck wind wheel vertical axis aerogenerator is accelerated the method for wind speed round, it is characterized in that: rotor joins by rotor bearing 4 and stator 8 at two ends about in the of 5; Upper strata wind wheel 6 is fixedlyed connected with the outside of rotor 5, and lower floor's wind wheel 3 is fixedlyed connected with the outer side surface of stator outer sleeve 9; The fan blade of described upper strata wind wheel 6 and lower floor's wind wheel 3 is connected and fixed around the wind wheel axle center is equidirectional respectively, and wind wheel 6 fan blade installation directions in upper strata are opposite with lower floor wind wheel 3 fan blade installation directions, and make the sense of rotation of upper strata wind wheel 6 and lower floor's wind wheel 3 reverse each other.
Structural representation of the present invention is illustrated in Fig. 1, as seen from the figure: the double-deck wind wheel vertical axis aerogenerator of realizing the method for described quickening wind speed round, comprise column 1, rotor 5, stator 8, upper strata wind wheel 6 and lower floor's wind wheel 3, it is characterized in that: described stator 8 outer surfaces and stator outer sleeve 9 internal surfaces fit tightly, the built-in rotor 5 of stator 8 center holes, described rotor joins by rotor bearing 4 and stator 8 at two ends about in the of 5, the bottom of described stator outer sleeve 9, be equipped with two column bearings 2 up and down, described column bearing 2 endoporus and described column 1 intimate are fitted, the internal surface of the outer surface of described column bearing 2 and described stator outer sleeve 9 fits tightly, and described upper strata wind wheel 6 is fixedlyed connected with the outside of described rotor 5; Described lower floor wind wheel 3 is fixedlyed connected with the outer side surface of described stator outer sleeve 9; The fan blade of described upper strata wind wheel 6 and lower floor's wind wheel 3 is connected and fixed around the wind wheel axle center is equidirectional respectively, and wind wheel 6 fan blade installation directions in upper strata are opposite with lower floor wind wheel 3 fan blade installation directions.
The shape of fan blade is shown in Fig. 2.The fan blade that illustrates described upper strata wind wheel 6 and lower floor's wind wheel 3 is the curved surface bending, and at least two of wind wheel windward number of sheets amounts are preferred more than 3 or 3, uniform.No matter wind direction is from where, always the power that the stress surface 10 that facings the wind of fan blade is subjected to is bigger than the power that lee face 11 is subjected to, because fan blade is around the equidirectional fixed installation in wind wheel axle center, so wind wheel all the time around a direction rotation, the wind energy utilization height, starts easily.Because wind wheel 6 fan blade directions in upper strata are opposite with lower floor wind wheel 3 fan blade windward side directions, so upper strata wind wheel 6 and lower floor's wind wheel 3 sense of rotation are reverse each other, promptly upper strata wind wheel 6 is the clockwise direction rotation again, and lower floor's wind wheel 3 is that counter clockwise direction is rotated; Vice versa.
The stator of generator is built-in with coil winding, rotor is built-in with permanent magnet, because coil winding motion cutting magnetic line in magnetic field of permanent magnet produces electric current, coil changes soon more, cutting magnetic line speed is just fast more, and finally the power that external circuit is provided of being drawn by brush is also just big more.Upper strata wind wheel 6 and lower floor's wind wheel 3 sense of rotation are reverse each other, and the speed of cutting magnetic line substantially exceeds the speed of the equidirectional rotation cutting magnetic line of two-layer wind wheel certainly, and little air quantity just can drive generating, so improved the output power of generator greatly.
Core of the present invention is by making the method for stator and rotor counter-rotating; improve the speed of coil cutting magnetic line; under the total inventive concept framework of the present invention; numerous embodiments can be arranged; stator disclosed herein is outside, rotor is at interior just wherein a kind of mode of execution, be to be understood that rotor outside, stator at the vertical axis aerogenerator of interior double-deck wind wheel counter-rotating also within the scope of protection of the invention.
The upper end portion of described rotor 5 is equipped with protective housing 7, is used to keep off the rain, prevents dust, sunshade.
China's wind resource is very abundant, and most regional mean wind velocitys are all at per second more than 3 meters, and in the outlying district with ward off the rural area partially, conventional electrical network does not reach the area as yet, can utilize the present invention to make small-sized wind power generator and be used for illumination; Urban construction is maked rapid progress, height is hugged and stood in great numbers, and at the mansion roof wind-driven generator is installed, and not only can alleviate the power load of peak of power consumption period on daytime electrical network, prevents that the electrical network power failure of operating a switch from influencing work and life, and is the scenery of one beauty.
