Embodiment
As shown in Figure 1, 2, a kind of sail leaf formula guiding wind-driven generator, include rotor 1, stator 2, chassis 3 and blade 4, be connected with generator bottom cover 5 on the chassis 3, stator 2 is located on the bottom cover 5, blade 4 is located in the rotating shaft 6 in the rotor 1, it is characterized in that: described blade 4 has a plurality of, each blade 4 adopts sail formula structure, straight inner side edge 7 is embedded in the rotating shaft 6 and parallel with rotating shaft 6 in the blade 4, outer side 8 in the blade 4 and base 9 curved types, the leaf surface of blade 4 are the along the circumferential direction crooked arc shaped surface of indent; A plurality of blades 4 distribute along the circumferencial direction of rotating shaft 6, are conical structure with the formed integral body of a plurality of blades after rotating shaft 6 is connected.The top of described blade 4 is provided with camber line accelerator card 10, can play the accelerated motion effect at gentle breeze and following wind, so it can just can start operation at the low wind speed of meter per second more than 1.The periphery of the bottom of described blade 4 is provided with safe edge 18; In the rotating shaft 6 and top that is positioned at blade 4 is provided with air velocity transducer 19, has the effect of surveying wind and overspeed protection.
As shown in Figure 3, be provided with the center-pole 11 vertical with chassis face 3 in the locating slot on described chassis 3, institute's art rotating shaft 6 is hollow, and rotating shaft 6 interts on center-pole 11.The inboard of described stator 2 is provided with many field coils 12, and many field coils 12 are circle distribution along the inner side surface of stator 2, and the periphery of the moving runner 13 in the rotor 1 is provided with the permanent magnet magnetic pole 20 of polylith along circle distribution.The winding design has multiple functional mode, when blower fan during in the slow-speed of revolution, it automatically reconfiguration to improve excitation voltage, increase output power, when blower fan during at high rotating speed, can change the field winding exciting voltage again and exert oneself, when overspeed, can also cooperate control system to produce plugging to reduce power.Adorning one one permanent magnet around the flywheel, reducing the field winding of rotor, simple technology has improved work efficiency and reliability.After wind energy conversion system normally started operation, the permanent magnet of rotor rotation just produced induction current when relatively having cut the stator coil winding, and this principle with common electric machine is the same.
In addition, moving runner 13 is made flywheel-type, and its diameter is bigger, and weight is heavier, and it can keep rotor when the strong and weak different wind of a burst of fluctuation attacks blade plateau has reduced fluctuation and speed rhythm that fitful wind produces.
As shown in Figure 4, described rotating shaft 6 is provided with two above magnetic suspension bearings 14, and magnetic suspension bearing 14 usefulness are not so that rotating shaft 6 has Mechanical Contact also can remain on aerial rotation.Described magnetic suspension bearing 14 is provided with the magnetic suspension bearing 15 of cross spacing and the magnetic suspension bearing 16 of vertical spacing, the magnetic suspension bearing 15 of described cross spacing, mainly contain initiatively pole coil 21 and constituted by moving magnet 22, the active pole coil 21 that is located in the magnetic suspension bearing 15 of cross spacing of rotating shaft 6 upper ends is fixed on the center-pole 11, the active pole coil 21 that is located in the magnetic suspension bearing 15 of cross spacing of rotating shaft 6 lower ends is encapsulated in the housing 17, be fixed in the rotating shaft 6 by moving magnet 22 and corresponding with active pole coil 21, described housing 17 is located on the chassis 3.The magnetic suspension bearing 16 of vertical spacing also is encapsulated in the housing 17, the magnetic suspension bearing 16 of vertical spacing is to be made of U-iron core 23, top pole coil 24, below pole coil 25 and butterfly permanent magnet 26, U-iron core 23 is fixed on the housing 17, top pole coil 24 and below pole coil 25 are located at the two ends of U-iron core 23, butterfly permanent magnet 26 is located in the rotating shaft 6, and above pole coil 24 and below between the pole coil 25.Rotor and center-pole are discontiguous, are suspended in aerial operation, can significantly reduce wind energy conversion system like this distance is changeed in the frictional force and the startup of center-pole, add the structure characteristic of its blade, just can strengthen the thrust of rotating shaft greatly.Therefore it just can start operation under very little wind speed.
Working principle: blade is like sail, make the sail of shape air blast when resembling marine wooden boat navigation, main shaft is straight perpendicular rotation, can capture the wind that 360 ° of all directions planes blow during its acting, so it can capture " three-dimensional ", and is reverse, or even the wind that downstream blows on " solid " " disorder ", a burst of property, therefore it is very high to the capturing ability of wind, and is also high to the utilization ratio of wind.According to of the shape analysis of this wind energy conversion system with its leaf production, it has the feature of following several respects to Wind Power Utilization: when rotating with the wind, when each blade of wind energy conversion system just begins during at the certain approximately small angle of down wind stressedly down with the wind, thrust can be rotated 160 degree, and as seen stressed when rotating is maximum with the wind; The top skew wind to the time, from shape and the lifting surface area of blade, the power of tearing open of this angle wind also be the maximum; The below sees that from the shape of blade its stressed effect is minimum during wind direction, and therefore the hypotenuse design has accelerator card on blade, can play increasing lifting force and thrust, makes wind energy conversion system also can start operation when gentle breeze; During upwind: from the composition of its blade, its reciprocal wind comes still can reinforcing act on reciprocal blade, because of its blade is formed body shape by several, it be 360 degree down with the wind, promote and push away the effect of tearing open so reverse wind can play too; During disorderly irregular air-flow, everybody sees that City Building is complicated, horizontal vertical staggered, be uneven, width differs, therefore cause roof roof airflow direction disorderly complicated, these air-flows of a burst of fluctuation also return the roof and clash into pneumatic equipment blades made from all directions, and the blade of its " three-dimensional " main body assembling is regardless of wind direction can increase thrust and lifting force effect equally.
Therefore be complicated from the visible wind energy conversion system of the present utility model of top analysis to the utilization of wind, high-octane, this is incomparable feature and advantages of various in the market wind-driven generators thus.
The structural manufacturing process of the formula that on making, breaks traditions, it does not need complicated heavy yaw device and control, does not need complicated heavy speed-change gear box yet, can also reduce heavy towering iron tower or the like, therefore manufacturing process is simple, can make middle-size and small-size power, also can manufacture the wind-driven generator of large-scale (MW class) power, cheap, handsome in appearance, as if the art work of wind, it will become the show of wind-power electricity generation, be convenient to very much utilize and promote.
