Two-blade downwind typhoon-resistant wind generating set

The utility model discloses a two-blade downwind typhoon-resistant wind generating set. Downwind direction design, namely, wind passes through the tail portion of a cabin of the wind generating set and then reaches the hub. Two symmetrical flange ports for connecting and mounting the blades are formed in the hub; the two blades are symmetrically arranged at two flange ports on the hub at an angleof 180 degrees; during normal work, 180-degree operation of the included angle between the wind direction and a cabin is achieved through control of a power source, blades of the unit are in a feathering (blade 90 degrees) state in a typhoon mode under the condition that no power source exists, passive yawing is achieved through adaptation of the unit to typhoon loads (directions), and it is guaranteed that the typhoon loads borne by the unit are the lowest. According to the utility model, during typhoon, the fan blades are all in a horizontal state, and the blades are prevented from pointingto the high altitude to be
