Abstract
The invention discloses a magnetically suspended and moved windmill generating device without a fan axis; a fan rotating ring of a fan rotating body is held in an external structure ring; the fan rotating body and the external structure ring are in a suspension status due to the collaborative work of a guiding suspension wheel and a permanent-magnet suspension mechanism; the collaborative work of an external horn-mouth fairing and an internal steamed-bun-shaped fairing work not only enlarges the air-inlet area, but also shrinks the area of a fan rotating mouth segment, thereby increasing the work wind speed of a rotating fan; a caterpillar-type magnetic motion machine on the external structure ring corresponds to a straight-line stator shoe arranged on the fan-rotating body, thereby realizing a non-contact transmission torque, reducing frictional resistance and increasing the generation efficiency of generators. As multiple generators adopted correspond to the fan rotating body and the number of the generators is determined by the local highest wind speed, the work quantity of accessing (quitting) generators is controlled by a microcomputer and transformed into an alternating current by an inverter and merged into a power system. When the wind direction changes, the microcomputer measures the changed angle according to an anemoscope and controls the magnetic motion machine to rotate for a corresponding angle so that a horn mouth faces the wind from time to time.

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 mechanism 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 is by wheel shaft 186, link firmly with bearing 18a, 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 the crawler belt rotor, and the spacing of p-m rotor 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 is measured according to flow direction vane (known equipment and known technology), thus rotate corresponding angle by control motor control crawler magnetic motivation 18, horn mouth is facingd the wind constantly, effectively work.
