After velocity of displacement superposition, the angle of attack in rotor face 311 premature in a certain specific radius point can be added to maximum, and planetary gear 3
Jacking force and revolution the arm of force 2 on (i.e. swinging axle) torque depend on rotor face 311 the angle of attack, the smaller torque of the angle of attack is bigger,
The more big then torsion of the angle of attack is smaller, therefore, is formed by the angle of attack in the rotor face 311 of planetary gear 3 and the blade 31 of planetary gear 3
The opposite structure of the angle of attack can effectively improve the torque of the revolution arm of force.
As shown in Fig. 6, the head-on adjuster is assemblied in shell 32, to drive opposite 32 turns of the shell of each blade 31
It is dynamic.It includes to adjust motor (showing not shown), driving gear 34 and bevel gear 33, the driving that the head-on adjuster, which can be,

The angle of attack of the revolution arm of force 2.Preferably, acting main shaft 51 can also connect electric brush slip ring, and the stationary part of the electric brush slip ring is connected to
Power supply and control system, the rotor portion of electric brush slip ring is fixed on acting main shaft 51, and connects each driving motor and oscillating motor
Power supply line be connected to rotor portion, can avoid causing the winding of route when the revolution arm of force 2 rotates through this structure.
Existing wind power generating set generally has a minimum starting torsion, and when traditional air vane is in gentle breeze item
When the torsion formed under part is less than minimum starting torsion, general default choice is abandoned generating electricity.In the present invention, when in same micro-
When under the conditions of wind, it can turn to form the biggish angle of attack by controlling the adjusting motor band movable vane piece 31 of each planetary gear 3, make to go
Star-wheel 3 realize the relatively high-revolving rotation under gentle breeze state, in combination with planetary gear 3 formed huge wind catching area, from
And biggish torsion can be formed to drive the main shaft arm of force 2 to rotate, and then realize acting power generation.This mode i.e. of the invention is compared to biography
For system windmill, the part wind energy utilization that traditional air vane can not be done work, and realize acting power generation, further to mention
The utilization rate of high wind energy.
31 width of blade depend on to workmanship main shaft 51 revolving speed setting, acting 51 setting speed of main shaft more it is slow then
Blade 31 is wider, and the acting more fast then blade 31 of 51 setting speed of main shaft is narrower.And as shown in Fig. 5, the revolution arm of force 2
The width of the blade 31 of the upper planetary gear 3 close to acting 5 one end of main shaft is greater than the planetary gear 3 far from acting 51 one end of main shaft
31 width of blade, and revolve the arm of force 2 on each planetary gear 3 on 31 quantity of blade from generator 5 to one end to the other end successively
It reducing, this two kinds of structures can be such that the distinguished and admirable resistance of each planetary gear 3 on the revolution arm of force 2 born gradually reduces from the inside to the outside,
To each planetary gear 3 on the arm of force 2 that makes to revolve revolving speed by 51 one end of acting main shaft to stepping up outside.In addition, the revolution arm of force 2
The length of the blade 31 of the upper planetary gear 3 close to acting 51 one end of main shaft is less than the planetary gear 3 far from acting 51 one end of main shaft
31 length of blade, under the conditions of same wind field, longer 31 wind catching area of blade is bigger, and the torque that it is generated is also bigger, in list
Acting is more in the time of position, and this structure can be such that the diameter of each planetary gear 3 on the revolution arm of force 2 gradually increases, and make planetary gear 3
Insertion dead space area gradually increases, to improve the utilization rate of wind energy.
In addition, as shown in Fig. 7, the angle of attack of the blade 31 on each planetary gear 3 on the revolution arm of force 2 is by acting main shaft
51 one end become larger to the other end, i.e., the angle of attack of the blade 31 of the planetary gear 3 far from generator 5 is greater than close to generator 5
The angle of attack of the blade 31 of planetary gear 3；And the angle of attack for turning the rotor face 311 of each planetary gear 3 on the arm of force 2 is equally led by acting
51 one end of axis becomes larger to the other end, i.e., the angle of attack in the rotor face 311 of the planetary gear 3 far from generator 5 is greater than close to power generation
The angle of attack in the rotor face 311 of the planetary gear 3 of machine 5.When the state windward of being in, the bigger angle of attack can the bigger reaction for bearing wind
Power is bigger, therefore improves the revolving speed of planetary gear 3, to make the revolving speed of each planetary gear 3 on the revolution arm of force 2 by 5 one end of generator
It is gradually increased to the other end, i.e., the revolving speed of the planetary gear 3 far from generator 5 is greater than the revolving speed close to the planetary gear 3 of generator 5.
The angle of attack that each blade 31 of planetary gear 3 is controlled by this angle of attack regulator, changes the reaction force of 31 wind-engaging of blade
Become, to achieve the purpose that the revolving speed for controlling 3 rotation of planetary gear, so that planetary gear 3 is no more than the limit speed of design, can reach
The effect that protection planetary gear 3 prevents planetary gear 3 from damaging.Additionally by the angle of attack in control swinging axle control rotor face 311, to change
The jacking force in rotor face 311, and then change the revolving speed (revolving speed for the main shaft 51 that does work) of the revolution arm of force 2, this mode can be used for protecting
Wind power generating motor group is protected, makes limit speed of the main shaft 51 no more than design that do work, maximumlly to improve the utilization rate of wind energy.
Specifically, swinging axle 34 can be driven to swing by control driving motor, to reduce the rotation of each planetary gear 3 in violent typhoon
The angle of attack of aerofoil 311, while the adjusting motor by controlling each planetary gear 3 is rotated to drive the blade 31 of each planetary gear 3 to put
It is dynamic, it is rocked to the blade 31 of each planetary gear 3 and is in the state compared with low incidence, to keep the rotational velocity of planetary gear 3 big
Width decline, and then realize control it is each revolution the arm of force 2 high wind speed under revolving speed, make wind power generating set high wind speed under the conditions of into
The fully loaded power generation of row, maximumlly to improve the utilization rate of wind energy.Conversely, when the wind field in light air (such as wind speed is 1.5m/s)
