1. The utility model provides a wind driven generator, contains the shell that has air intake and air outlet, sets up generator body in the shell which characterized in that:

  • the generator body comprises an outer stator, a rotor which is arranged in the outer stator and provided with a hollow part, an inner stator which is arranged in the hollow part of the rotor, and fan blades which are distributed in the shell and connected with the rotor;

    wherein the outer stator, the rotor and the inner stator are all coaxially arranged;

    the wind driven generator also comprises first supporting columns distributed in the shell and used for supporting the outer stator, and second supporting columns distributed in the shell and used for supporting the inner stator;

    the two ends of the first supporting column are respectively and fixedly connected with the shell and the outer stator, and the two ends of the second supporting column are respectively and fixedly connected with the shell and the inner stator;

    the rotor comprises a rotor body arranged in the outer stator and a rotor shaft connected with the rotor body;

    the head part and the tail part of the rotor shaft are partially exposed out of two ends of the outer stator respectively;

    the fan blades are respectively arranged at the head and the tail of the rotor shaft in an equidistant surrounding manner;

    the head and the tail of the rotor shaft are respectively provided with a groove body for fixing the fan blade in an annular mode;

    the groove bodies arranged at the head part of the rotor shaft and the groove bodies arranged at the tail part of the rotor shaft are alternately arranged;

    the inner stator comprises a stator body arranged in the rotor and a stator shaft connected with the stator body;

    the head part and the tail part of the stator shaft are respectively exposed out of two ends of the rotor and are respectively fixedly connected with the shell wall of the shell through the second supporting column;

    the wind driven generator also comprises a first guard ring for fixedly connecting all the fan blades arranged at the head of the rotor shaft in a surrounding manner, and a second guard ring for fixedly connecting all the fan blades arranged at the tail of the rotor shaft in a surrounding manner;

    the length of each fan blade arranged at the head of the rotor shaft in a surrounding manner is equal to that of each fan blade arranged at the tail of the rotor shaft in a surrounding manner, and the first guard ring and the second guard ring are fixedly connected with the end parts of the corresponding fan blades;

    grooves used for being inserted by the end portions of the fan blades are distributed on the surfaces of the inner edges of the first protective ring and the second protective ring.
