Technical field
The invention belongs to technical field of wind power generation, and in particular to blade automatic deploying and retracting generates electricity without negative torque vertical axis wind
Machine.
Background technique
Wind-driven generator is to convert wind energy into mechanical work, and mechanical work drives rotor rotation, the electricity of final output alternating current
Power equipment.However, the existing various types of wind-driven generators occurred on the market at present all can only can just be opened at 4-5 grades of wind-force or more
Dynamic rotary electrification, and wind-force density utilization rate is very low, only 13-14%.To find out its cause, existing wind-driven generator structure design
Have the defects that it is certain, when whole wind surfaces rotate under the action of the wind, always with the presence of 1 or 2 blade parts
Negative torque, to generate resistance or in-fighting to the rotation of alternator shaft, weaken rotation required away from, starting wind-force it is just higher,
The velocity of rotation for having slowed down rotation axis, necessarily reduces generated energy, reduces the generating efficiency of wind-driven generator.Therefore, it is necessary to right
The structure of existing wind-driven generator is improved further.
Summary of the invention
Object of the present invention is to：Blade automatic deploying and retracting is intended to provide without negative torque vertical shaft type aerogenerator, not only starts wind
Power is down to 2-3 grades by 4-5 grades, considerably increases a year generating dutation；And it can be to avoid the generation of negative torque, under same wind-force
Revolving speed can be improved, promote generated output, greatly promote the generating efficiency of wind-driven generator, can increase by 200% annual electricity generating capacity.
To realize the above-mentioned technical purpose, the technical solution adopted by the present invention is as follows：
Blade automatic deploying and retracting is without negative torque vertical shaft type aerogenerator, including column on the ground, institute can be fixedly mounted
It states and generator is installed at the top of column, controller is installed on the generator, the spindle wall that turns at the top of the generator is consolidated
For Dingan County's dress there are four the steering engine of radially even distribution, the swing arm of four steering engines is fixedly installed with blade I, blade respectively
II, blade III and blade IV, the blade I, blade II, blade III and blade IV are circular arc vane, the leaf
Piece I and blade III central symmetry, the blade II and blade IV central symmetry, the blade I, blade II, blade III and
Wind direction and wind velocity sensor is mounted on the windward side of blade IV, wind direction and wind velocity sensor described in four is defeated with controller
Enter end connection, four branches of output end point of the controller are connect with four steering engines respectively.
Using technical solution of the present invention, when the windward side of blade I and blade IV are contacted with wind-force, at this point, blade II,
The leeward of blade III is contacted with wind-force, and blade II, blade III will generate negative torque, in order to avoid the generation of negative torque,
Controller controls steering engine movement corresponding with blade II, blade III, so that the swing arm of the two steering engines be made to be swung up 90 °
To plumbness, blade I and blade IV are generated electricity by turned, when blade IV rotates counterclockwise 90 ° to the position of 1/2 π, leaf
The leeward of piece IV is contacted with wind-force, and controller controls blade IV corresponding steering engine movement, thus make the swing arm of this steering engine to
Upper to swing 90 ° to plumbness, and at this point, blade II rotates counterclockwise 90 ° of positions to 3/2 π, the windward side of blade II starts
It is contacted with wind-force, controller controls blade II corresponding steering engine movement, to make the swing arm of this steering engine to 90 ° of lower swing to water
Level state bears wind-force and generates torque, so recycles, when blade turns at 1/2 π, the swing arm of corresponding steering engine is swung up
90 ° to plumbness, to avoid the generation of negative torque；Meanwhile when blade turns at 3/2 π, the swing arm of corresponding steering engine is downward
90 ° are swung to horizontality receiving wind-force generation torque.The present invention not only starts wind-force and is down to 2-3 grades by 4-5 grades, greatly increases
Year generating dutation；And revolving speed can be improved under same wind-force to avoid the generation of negative torque, generated output is promoted, greatly
The big generating efficiency for promoting wind-driven generator, can increase by 200% annual electricity generating capacity.
Further, the wind direction and wind velocity sensor be ultrasonic wave vortex air velocity transducer, propeller air velocity transducer,
Any one in hot-wire array sensor, hot diaphragm type air velocity transducer, the controller are single-chip microcontroller.Such structure is set
Meter, not only the acquisition of wind direction and wind velocity signal is more accurate, but also signal calculating and processing speed it is very fast.
