Auxiliary adjusting device of variable pitch system

The utility model provides a variable pitch system auxiliary adjusting device which comprises a fan shell, three steering units are evenly distributed on the fan shell in the circumferential direction, blades are connected to the steering units, and a fixing unit is arranged in the fan shell and connected with the blades. By arranging the auxiliary adjusting device in the wind driven generator, when the blades meet strong wind, the angles of the blades can be automatically deflected, the blades can be prevented from being damaged, generator damage caused by overload of the generator can be prevented, power control is not needed, and therefore the auxiliary adjusting device can also be arranged in a large wind driven generator; emergency use under the condition that the variable pitch system is damaged or power supply is not available is prevented, and the rotating angle of the blade can be fixed through the fixing unit when the variable pitch system is used for control. 本实用新型提供一种变桨系统辅助调节装置，包括，风机壳体，所述风机壳体周向均布有
