Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand following embodiment only is not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
Refer to shown in Fig. 1 to 3, the invention discloses the medium-sized magnetic suspending wind turbine generator of a kind of resistance lift-type combined type, comprise supporting other assemblies post tower 20, be fixed in post tower 20 tops fixed plate 30, carry and be fixed in generator motor 40, the rotor plate 50 coordinated with generator motor 40 on fixed plate 30, be located at the blade rack 71 that outer on generator motor 40 turn servo-motor 60, connection of rotating section 42 and rotor plate 50, the blade 72 that is installed on support 71 outsides.Be provided with the roller unit 32 that magnetic levitation system 31 reaches in order to supplemental support between described fixed plate 30 and rotor plate 50.The setting of magnetic levitation system 31 can make rotor plate 50 be carried on fixed plate 30 by this magnetic levitation system 31, and the frictional force that magnetic levitation system 31 produces when rotor plate 50 rotation is minimum to ignoring, make the rotation of rotor plate 50 more efficient and without wearing and tearing.Described generator motor 40 comprises the columniform rotation section 42 of carrying and being fixed in the first cylinder 41 on fixed plate 30 and rotating around the first cylinder 41.The outer surface convex of this rotation section 42 is provided with spline 43, and in the present embodiment, described spline 43 is provided with 10.And these 10 splines are distributed in the outer surface of described rotation section 42 uniformly.Be fixed with at least one interference part 51 on described rotor plate 50, this interference part 51 is inserted between described two splines 43 and with two splines 43 interferes, when blade 72 rotates, blade 72 drives blade rack 71 and rotor plate 50 rotates, thereby the interference part 51 of being fixed on rotor plate 50 is rotated thereupon and drives rotation section 42 rotations by the interference with spline 43, so that generator motor 40 is worked and generates electricity.What described blade 72 was lengthwise is tabular, and being installed on blade rack 71 of tilting, and the cross section of blade 72 be shaped as aerofoil profile (shape of aircraft airfoil section), under the effect of wind-force, described blade 72 not only produces resistance and can produce lift like this, wherein, the resistance band moving vane 72 produced rotates, and the lift produced can make the pressure of 72 pairs of rotor plates 50 of blade reduce and the centrifugal force of blade 72 while rotating diminishes, and more is conducive to the stable of blade 72 rotations.Described blade rack 71 comprise first support 711 on the first support 711 of being positioned at vertical plane and vertical connecting plane and to side extended the second support 712, this second support 712 forms three-legged structures to improve the intensity of whole blade rack 71.Refer to shown in Fig. 4, described roller unit 32 comprises ball 321, supports the seat 322 of ball 321 and the guide rail 323 coordinated with ball 321.What described seat 322 and guide rail 323 were selected is installed on fixed plate 30 or rotor plate 50.This roller unit 32 is arranged at the periphery of magnetic levitation system 31, and assisted Extraction is for the support between fixed plate 30 and rotor plate 50.In the present embodiment, described blade rack 71 also can be connected with described interference part 51 and rotor plate 50, to improve bulk strength.
Please consult shown in Fig. 1 to 3, the described outer servo-motor 60 that turns comprises the second cylinder 61 be installed on the first cylinder 41 and the outer transfer part 62 rotated around the second cylinder 61 again.Should outer turn using method and the effect of servo-motor 60 in this wind-driven generator is: when wind-force is less, when the more difficult rotation of blade 72 or rotation can't drive 40 generating of generator motor slowly, can start the outer servo-motor 60 that turns to blade 72 acceleration rotations.Owing to having adopted magnetic levitation system 31, be easy to form inertia and produce and can drive generator motor 40 and rotate and generate electricity after blade 72 accelerates to rotate, and the sub-fraction in the electric power that generator motor 40 produces offers the outer servo-motor 60 that turns and can accelerate to blade 72, can when wind-force is less, offer blade 72 and accelerate the power rotated therefore install the outer servo-motor 60 that turns additional, with in the situation that wind-force is less still can generate electricity.In addition, when certain wind-force or blade 72 rotating speeds being arranged when enough, the described outer servo-motor 60 that turns can be generated electricity in order to the motor of generating equally as second, has further increased generating efficiency and the generating capacity of whole wind-driven generator.And in the situation that wind-force to cross ambassador's blade 72 rotating speeds too fast, the rotation of blade 72 is difficult to keep stable and the situation of waving occurs because of too fast rotating speed, at this moment can make outer turn outer transfer part 62 generations of servo-motor 60 and the rotation of described blade 72 direction of rotation, thereby provide certain braking to blade 72, reduce the rotating speed of blade 72 and make the rotation of blade 72 more stable.In sum, this is outer turns servo-motor 60 have driving simultaneously in this wind-driven generator, generate electricity, brake three kinds of functions, and environmental suitability and the generating efficiency of whole wind-driven generator all is significantly improved.
In the present invention, rotation section 42 outer surfaces of described generator motor 40 are provided with spline 43, thus make rotation section 42 directly by spline 43 transmissions without other transmission device is set again.The integrated quantity that reduces spare part of spline drived and generator motor 40, reduced manufacture cost, improved efficiency of assembling, can embody the advantage of miniaturization simultaneously.In the present embodiment, the interference part 51 that employing is fixed on rotor plate 50 coordinates with spline 43, and in other embodiments, can adopt spline housing 51 ' as shown in Figures 5 and 6 to coordinate with spline 43, and the interference part 52 ' in spline housing 51 ' is thought in interference part.
