20 is inlayed and is fixed in the opening 6b '.The effect of interior cowling is that the wind that will change fan hub 1a place is guided on the commentaries on classics fan 1b, has also improved wind speed simultaneously.Outer cowling 7 is fixed on the both sides of external structure ring 2 symmetrically, is tubaeform housing.Its effect is to enlarge air-admitting surface, and the wind at external structure ring 2 places and wind in addition are guided to be changeed on the fan 1b, has also improved wind speed simultaneously.On the cowling 7, being provided with changes fan beam 20 outside, is provided with magnetic suspension bearing 20a in the commentaries on classics fan beam 20 corresponding fan 1a ' position of changeing, and both cover offs link firmly.It can also be seen that from Figure 14 be provided with rotating shaft 14 in the central authorities of round platform 5, the central authorities on chassis 4 are provided with bearing 15, both align up and down, link firmly.Its effect has two, one, makes the steering shaft on chassis 4, and the 2nd, the pulling force that topples of windmill is delivered in the rotating shaft 14, between chassis 4 and round platform 5, also be provided with permanent magnet suspension mechanism 9 ', turn to crawler magnetic motivation 18.Figure 19 is Figure 14 D-D generalized section, as can be seen from Figure 19, on the table top 5a of round platform 5, is the center with rotating shaft 14, is arranged with the beam 16 that crouches radially, is provided with annular permanent magnet suspension mechanism 9 ' and annular straight stator boots 17 on beam 16 for sleeping in.Figure 20 is Figure 14 E-E generalized section, as can be seen from Figure 20, is provided with the permanent magnet suspension structure 9 ', the crawler magnetic motivation 18 that are circular layout below chassis 4, is provided with bearing 15 in central authorities.Be arranged on last permanent magnet suspension mechanism 9 ' below the chassis 4 with to be arranged on the following permanent magnet suspension mechanism 9 ' center of rotation that crouches above the beam 16 identical, radius is equal, align up and down, and same sex permanent-magnet pole is corresponding, and its permanent magnet expulsive force gets up chassis 4 suspensions.The structure of described permanent magnet suspension mechanism 9 ' up and down is identical, and the device of the permanent magnet suspension mechanism 9 that is adopted between the permanent-magnet suspender that is adopted and aforementioned commentaries on classics fan body 1 and the external structure ring 2 is identical, and therefore, its structure characteristic be not repeated in this description.Should be noted that both are different to the requirement of suspending power size, should be according to the load of chassis 4 and top object thereof, the magnetic intensity of application of known is calculated formula, or commercially available business software is calculated the volume size and the distance each other of permanent magnet.Also available small test method is determined.The crawler magnetic motivation 18 that is arranged on below the chassis 4 is identical with the center of rotation that its below is arranged on the annular straight stator boots 17 above the beam 16 that crouch, and radius equates, up and down correspondence.Figure 21 turns to crawler magnetic motivation 18 horizontal working condition enlarged diagrams for chassis 4, and Figure 22 vertically is hoop (C a to) working condition schematic representation for chassis 4 turns to crawler magnetic motivation 18.As can be seen, linear stator boots 17 are equidistantly arranged by ferromagnetism bar steel and are formed from Figure 21, Figure 22.Crawler magnetic motivation 18 is made of bearing 18a, Athey wheel 18b, crawler belt (chain) 18c, permanent-magnet pole 18d.Athey wheel 18b links firmly by wheel shaft 18b ' and bearing 18a, and crawler belt 18c is looped around the periphery of Athey wheel 18b, and permanent-magnet pole 18d is fixed on crawler belt 18c by rotor base 18d ' (by the carbon steel manufacturing) and upward forms shoe.The band rotor, the spacing of rotor magnetic pole 18d equates with the spacing of linear stator boots 17.Motor 19 be fixed on chassis 4 below, its rotatingshaft 19 ' is connected with the wheel shaft 18b ' of crawler magnetic motivation.When motor 19 driving track formula magnetic motivations 18 are rotated, will permanent-magnet pole 18d and linear stator boots 17 staggering on sense of rotation take place, when generation is staggered, just produced and driven the torsion (suction) that rotate on chassis 4, increase along with the value that staggers, torsion (suction) increases thereupon, when the value that staggers reaches 70% left and right sides of permanent magnet 18d cross-section size, the torsion maximum value will appear, afterwards along with the increase torsion that staggers reduces gradually.Turn to the effect of crawler magnetic motivation to be, when wind direction changes, the angle changing that microcomputer (commercially available) is measured according to flow direction vane (commercially available), control crawler magnetic motivation 18 is rotated corresponding angle, horn mouth is facingd the wind constantly, effectively work.
Using advantage of the present invention is: the unit generated output is huge, mechanical resistance is low, power consumption penalty is minimum, the generating wind speed is wide, cost of electricity-generating is low.
