Embodiment
Below in conjunction with accompanying drawing and embodiment; Further illustrate the present invention; Should understand following embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
See also 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 in order to the post tower 20, the fixed plate 30 that is fixed in post tower 20 tops that support other assemblies, carry and be fixed in generator motor 40 on the fixed plate 30, the rotor plate 50 that cooperates with generator motor 40, be located at outer commentaries on classics servo-motor 60 on the generator motor 40, be connected rotation section 42 and rotor plate 50 blade rack 71, be installed on the blade 72 in support 71 outsides.Be provided with the roller unit 32 that magnetic levitation system 31 reaches in order to supplemental support between said fixed plate 30 and the rotor plate 50.The setting of magnetic levitation system 31 can make rotor plate 50 be carried on the fixed plate 30 through this magnetic levitation system 31; And the frictional force that magnetic levitation system 31 produces when rotor plate 50 rotation is minimum to ignoring, and makes the rotation of rotor plate 50 more efficient and do not have wearing and tearing.Said generator motor 40 comprises the columniform rotation section 42 of carrying and being fixed in first cylinder 41 on the fixed plate 30 and rotating around first cylinder 41.The outer surface of this rotation section 42 outwards convexes with spline 43, and in this mode of execution, said spline 43 is provided with 10.And these 10 splines are distributed in the outer surface of said rotation section 42 uniformly.Be fixed with at least one interference part 51 on the said rotor plate 50; This interference part 51 is inserted between said two splines 43 and with two splines 43 interferes; When blade 72 rotates; Blade 72 drives blade racks 71 and rotor plate 50 rotates, and rotates thereupon and drives rotation section 42 through the interference with spline 43 and rotate thereby be fixed in interference part 51 on the rotor plate 50, so that generator motor 40 is worked and generated electricity.Said blade 72 is the tabular of lengthwise; And being installed on the blade rack 71 of tilting, and the cross section of blade 72 be shaped as aerofoil profile (shape of aircraft airfoil section), said blade 72 not only produces resistance and can produce lift under the effect of wind-force like this; Wherein, The resistance that produces drives blade 72 and rotates, and the lift that produces can make the pressure of 72 pairs of rotor plates 50 of blade reduce and the centrifugal force of blade 72 when rotating diminishes, and helps the stable of blade 72 rotations more.Said blade rack 71 comprises first support 711 that is positioned at vertical plane and connects first support 711 of vertical plane and to extended second support 712 in side, this second support 712 forms the intensity of three-legged structures with raising whole blade support 71.See also shown in Figure 4ly, said roller unit 32 comprises ball 321, supports the seat 322 of ball 321 and the guide rail 323 that cooperates with ball 321.What said seat 322 and guide rail 323 were selected is installed on fixed plate 30 or the rotor plate 50.This roller unit 32 is arranged at the periphery of magnetic levitation system 31, and assisting provides the support between fixed plate 30 and the rotor plate 50.In this mode of execution, said blade rack 71 also can be connected with said interference part 51 and rotor plate 50, to improve bulk strength.
Please consult shown in Fig. 1 to 3, the said outer servo-motor 60 that changes comprises second cylinder 61 that is installed on first cylinder 41 and the outer transfer part 62 that rotates around second cylinder 61 again.Should outer change method for using and the effect of servo-motor 60 in this wind-driven generator be: less when wind-force, blade 72 is difficult to rotate or rotates slow and can't drive 40 generatings of generator motor the time, can start the outer servo-motor 60 that changes and quicken to rotate for blade 72.Owing to adopted magnetic levitation system 31; After blade 72 quickens to rotate, be easy to form inertia and produce and to drive generator motor 40 and rotate and generate electricity; And the sub-fraction in the electric power that generator motor 40 produces offers the outer servo-motor 60 that changes and quickens for blade 72; Can when wind-force is less, offer the power that blade 72 quickens rotation so install the outer servo-motor 60 that changes additional, under the less situation of wind-force, still can generate electricity.In addition, when certain wind-force or blade 72 rotating speeds were enough, the said outer servo-motor 60 that changes can generate electricity in order to the motor of generating as second equally, has further increased the generating efficiency and the generating capacity of whole wind power generator.And cross under the too fast situation of ambassador's blade 72 rotating speeds at wind-force; The rotation of blade 72 is difficult to keep stable and situation that occur waving because of too fast rotating speed; At this moment can make outer change outer transfer part 62 generations of servo-motor 60 and the rotation of said blade 72 direction of rotation; Thereby to blade 72 certain braking is provided, reduces the rotating speed of blade 72 and make the rotation of blade 72 more stable.In sum, this is outer to change servo-motor 60 and in this wind-driven generator, has drivings, generating simultaneously, brake three kinds of functions, and the environmental suitability and the generating efficiency of whole wind power generator all had significant improvement.
In the present invention, rotation section 42 outer surfaces of said generator motor 40 are provided with spline 43, thereby make rotation section 42 directly need not to be provided with other transmission device through spline 43 transmissions again.The integrated quantity that reduces spare part of spline transmission and generator motor 40 has reduced manufacture cost, has improved efficiency of assembling, can embody the advantage of miniaturization simultaneously.In this mode of execution; The interference part 51 that employing is fixed on the rotor plate 50 cooperates with spline 43; And in other embodiments, can adopt like Fig. 5 and spline housing 51 ' shown in Figure 6 to cooperate with spline 43, and the interference part 52 ' in the spline housing 51 ' is thought in the interference part.
