Operation principle is as shown in figure 3, arrives stream wind speed is V in figure, and blade rolling tangential speed is U, the vector of two speed
It is W with the relative wind velocity that blade is subject to is obtained, α is the angle of attack, and β is propeller pitch angle.Although vertical shaft fan is without to wind, blade rotation
In one week turned, angle α (i.e. the angle of attack) moment of blade and relative wind direction is all being changed, and vane airfoil profile and size are fixed
Afterwards, blade can correspond to an optimal angle of attack value α, blade is resulted in the tangential force of maximum, therefore, in the case of operable
The angle β (i.e. propeller pitch angle) of linear velocity is rotated by adjusting the blade string of a musical instrument so that keep optimal attack angle α in blade rotation,
Vertical shaft fan can be allowed to obtain maximum efficiency.Simultaneously as the change of wind direction and wind velocity is, it is necessary to right before and after vertical shaft fan
The propeller pitch angle β of blade carries out the adjustment of different angles in real time.So, by the monitoring to arrives stream wind speed wind direction and rotation speed of fan,
Optimal propeller pitch angle change function Δ β (θ, λ) in real time is calculated after processing, according to Bian Jiang executing agencies are to current vane and become oar
The feedback of motor status, control Bian Jiang executing agencies carry out change oar, to approach and maintain blower fan to run under nominal power.Work as wind
Speed exceed can operating air velocity when, by controlling blade to be braked (i.e. feathering β=90 °) so that blade generation aerodynamic drag, hinder
Hinder blower fan to rotate, reduce rotation speed of fan, protection blower fan is without prejudice.
Workflow such as Fig. 4, after pitch-controlled system receives startup order, the monitoring surrounding wind speed and direction of anemoclinograph 3
Situation, the monitoring rotation speed of fan situation of speed probe 4, and real time data is radioed into central processing module 1, when wind speed reaches
To blower fan threshold wind velocity scope, central processing module 1 issues instructions to Bian Jiang executing agencies 2, and Bian Jiang executing agencies 2 feed back in real time
The orientation of blade 10 and the position of pitch motor 13, pitch motor 13 is driven according to the order-driven module 12 of central processing module 1
Blade 10 is controlled to carry out change oar, now fan blade award setting makes blower fan obtain larger staring torque in larger angle, this
When pitch-controlled system be start-up mode；When blower fan starts after rotation, faster rotational speed, central processing module 1 is received by processing
The real-time rotary speed information of wind speed and direction information and blower fan main shaft 7, control changes function according to the optimal propeller pitch angle of controlled blower fan
The each blade 10 of Δ β (θ, λ) (θ is blower fan azimuth, and λ is tip speed ratio) controls follows wind speed and direction to change in real time, makes blower fan
Optimal efficacy is obtained, now pitch-controlled system is rated power mode；When wind speed exceedes rated wind speed or rotating speed more than specified turn
When fast, central processing module 1 can send instruction, reduce and become oar action, and propeller pitch angle is maintained at into smaller angle operation, blower fan is kept
Run near rated speed, if wind speed continues to increase, central processing module 1 will send instruction according to wind speed, rotary speed information, control
The blade 10 of part processed becomes oar and enters on-position, and other blades continue to remain on angle, to reduce aerodynamic power
Square, maintains rotation speed of fan, and now blower fan may continue to work, and now pitch-controlled system is super rated wind speed pattern；When wind speed rises
More than can operating air velocity when, central processing module 1 judge can not continue to run with after, can send instruction one by one control blade 10 make
It is dynamic, and the power supply of pitch motor 13 is cut off, the self-locking of blade 10 is ensured fan safe, now pitch-controlled system is braking protected mode.
Each different operational mode can switch mutually according to blower fan virtual condition.
Flow such as Fig. 5 during shutdown, after pitch-controlled system receives halt instruction, central processing module 1 issues instructions to change
Wireless communication module in oar executing agency 2, Bian Jiang executing agencies 2 is received after instruction, controls each blade 10 to enter according to instruction
Enter on-position, that is, issuing instructions to the driving of drive module 12 pitch motor 13 makes blade 10 carry out feathering action (propeller pitch angle β changes
For 90 °), rear drive module 2 close pitch motor 13 make its self-locking, then drive module 12 is voluntarily closed, become oar perform machine
Wireless communication module in structure 2 is detected after drive module 12 and pitch motor 13 all close, and feeds back central processing module 1, in
Centre processing module 1, which is received, sends instruction closing anemoclinograph 3 and speed probe 4 after feedback, finally closing is whole to become oar system
System.
The present invention does not address part and is applied to prior art.
