1. the vane support wing structure of a vertical axis aerogenerator, comprise fixing supporting wing (1), it is characterized in that, also comprise and rotate supporting wing (2), one end (21) of described rotation supporting wing is connected with one end (12) of fixing supporting wing and can rotates around one end of this fixing supporting wing (12);

  • One end (21) of described rotation supporting wing is provided with rotary middle spindle (3) with the joint, one end (12) of described fixing supporting wing, and described rotation supporting wing (2) can rotate around this rotary middle spindle (3);

    The other end (22) that rotates supporting wing is to be fixedly connected with blade;

    At the other end (22) of above-mentioned rotation supporting wing, connect the controlling component (4) of capable of controlling rotary supporting wing (2) around the angle of swing (β

    ) of rotary middle spindle (3) rotation, fixing supporting wing one end (12 '"'"') that this controlling component (4) is adjacent with such rotation supporting wing is connected, and with the method, along wind wheel one direction, sets gradually several controlling componenies (4);

    Described controlling component (4) is that the angle variation of supporting wing (2) around the angle of swing β

    of rotary middle spindle (3) rotation rotated in elastic member control, controlling method is;

    rotating supporting wing initial angle is β

    1, correspondence blade when initial position has a fixing corner α

    1, when wind wheel rotates under wind speed is less than rated wind speed, rotate supporting wing and be limited at initial position, fixing supporting wing 1 and the angle beta 1 rotating between supporting wing 2 remain unchanged, and blade rotating angle α

    1 remains unchanged;

    When wind wheel is greater than after rated wind speed at wind speed, rotating speed also exceedes rated speed, the angle beta 1 rotating between supporting wing 2 and fixing supporting wing 1 diminishes gradually as β

    2, make blade rotating angle by less forward angle to negative sense Angulation changes, blade rotating angle α

    1 is from forward Angulation changes to negative sense angle [alpha] 2.
