Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, following embodiment should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
Refer to shown in Fig. 1 to 3, the invention discloses a kind of resistance lift-type type compound medium magnetic suspension wind driven, the post tower 20 comprising supporting other assemblies, the fixed plate 30 being fixed on post tower 20 top, carry and be fixed on the generator motor 40 on fixed plate 30, the rotor plate 50 coordinated with generator motor 40, to be located on generator motor 40 outer turn servo-motor 60, connection of rotating portion 42 and rotor plate 50 blade rack 71, be installed on blade 72 outside support 71.Magnetic levitation system 31 and the roller unit 32 in order to supplemental support is provided with 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 rotates is minimum to negligible, make the rotation of rotor plate 50 more efficient and without wearing and tearing.Described generator motor 40 comprise carry and the first cylinder 41 be fixed on fixed plate 30 and around first cylinder 41 rotate columniform rotation section 42.This rotation section 42 be outwardly convexly equipped with spline 43, 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.Described rotor plate 50 is fixed with at least one interference part 51, this interference part 51 to be inserted between described two splines 43 and to interfere with two splines 43, when blade 72 rotates, blade 72 drives blade rack 71 and rotor plate 50 to rotate, thus the interference part 51 be fixed on rotor plate 50 is rotated and by driving rotation section 42 to rotate with the interference of spline 43, is generated electricity to make generator motor 40 work thereupon.Described blade 72 is the tabular of lengthwise, and tilt be installed on blade rack 71, and the shape of the cross section of blade 72 is aerofoil profile (shape of aircraft airfoil section), described blade 72 not only produces resistance and can produce lift so under the action of the forces of the wind, wherein, the resistance band moving vane 72 produced rotates, and the lift produced can make the pressure of blade 72 pairs of rotor plates 50 reduce and the centrifugal force of blade 72 when rotating diminishes, advantageously in blade 72 rotate stable.Described blade rack 71 comprises and is positioned at the first support 711 of vertical plane and the first support 711 of vertical connecting plane and the second support 712 extended to side, and this second support 712 forms three-legged structure to improve the intensity of whole blade rack 71.Refer to shown in Fig. 4, described roller unit 32 comprises ball 321, the seat 322 supporting 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.
Referring again to 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.This is outer turns the using method of servo-motor 60 in this wind-driven generator and effect is: when wind-force is less, the more difficult rotation of blade 72 or rotate comparatively slow and cannot drive electrical generators motor 40 when generating electricity, and can start the outer servo-motor 60 that turns and accelerate to rotate to blade 72.Owing to have employed magnetic levitation system 31, be easy to form inertia and produce and can rotate and generate electricity by drive electrical generators motor 40 after blade 72 accelerates rotation, and turn servo-motor 60 outside the sub-fraction in the electric power that generator motor 40 produces is supplied to accelerate to blade 72, therefore turn servo-motor 60 can be supplied to blade 72 acceleration rotation power when wind-force is less outside installing additional, still can generate electricity when wind-force is less.In addition, when having certain wind-force or blade 72 rotating speed is enough, the described outer servo-motor 60 that turns can generate electricity in order to the motor of generating equally as second, further increases generating efficiency and the generating capacity of whole wind-driven generator.And when wind-force cross ambassador's blade 72 rotating speed too fast, the rotation of blade 72 is difficult to because of too fast rotating speed keep stable and occurs the situation of waving, at this moment the outer outer transfer part 62 turning servo-motor 60 can be made to produce the rotation with described blade 72 direction of rotation, thus 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 in this wind-driven generator, has driving, generating, braking three kinds of functions simultaneously, is all significantly improved the environmental suitability of whole wind-driven generator and generating efficiency.
In the present invention, rotation section 42 outer surface of described generator motor 40 is provided with spline 43, thus make rotation section 42 directly by spline 43 transmission without the need to arranging other transmission device again.Spline drived and the integrated quantity decreasing spare part of generator motor 40, reduce manufacture cost, improve efficiency of assembling, can embody the advantage of miniaturization simultaneously.In the present embodiment, the interference part 51 be fixed on rotor plate 50 is adopted to coordinate with spline 43, and in other embodiments, spline housing 51 ' as shown in Figures 5 and 6 can be adopted to coordinate with spline 43, and the interference part 52 ' in spline housing 51 ' is thought in interference part.
