The method of work of above-mentioned umbrella-shaped wind driven generator group is: the output power being detected wind power generating set by controller, when output power is less than or equal to rated power, then blade is in open mode, once output power is greater than rated power, then controller accessory drive work, drive unit drives spiral rotating, the rotation of nut impels axle straight line motion, axle is in linear motion, under the effect of connecting rod, the blade be hinged on generator amature is folded, control output power in setting range, described setting range refers to the maximum output of generator, as output power is less than or equal to rated power, in the work of controller accessory drive, drive unit drives nut counterrotating, then blade is opened.
The working principle of the umbrella-shaped wind driven generator of said structure is: umbrella-shaped wind driven generator group in normal operation, blade is in open mode, once detect that the output power of generator set is greater than rated output power, then accessory drive work, drive unit drives nut to rotate, because axle is meshed with nut, therefore, axle meeting straight line motion, axle is in linear motion, axle is with moving vane to fold under the effect of connecting rod, to reduce the wind sweeping area of blade, thus under strong wind, control the output power of generator set, serve the object of protection wind power generating set.In the present invention, the angle that folds of blade is determined by wind speed and air quantity.
As improvement, the driven gear that described drive unit comprises drive motor, is arranged on the driving gear on drive motor and is arranged on nut, described driving gear and driven gear are meshed.The structure of above-mentioned drive unit is simple, and cost is low.
As improvement, platform is provided with the supporting base of more than two, supporting base is provided with linear bearing, described axle is supported by linear bearing.By supporting base back shaft, the installation stability of axle can be improved, and the precision degree of axle movement can be improved, the rigidity of raising axle of being good at.
As improvement, column is provided with controller, the input end of controller is connected with power detector, and the output terminal of controller connects drive motor.
