Technical field

The utility model belongs to technical field of wind power generation, and in particular to blade automatic deploying and retracting is without negative torque vertical axis wind Generator.

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.

Utility model content

The utility model aim is: being intended to provide blade automatic deploying and retracting without negative torque vertical shaft type aerogenerator, not only opens Dynamic wind-force 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, in same wind Revolving speed can be improved under power, promote generated output, greatly promote the generating efficiency of wind-driven generator, can increase by 200% year power generation Amount.

To realize the above-mentioned technical purpose, the technical solution adopted in the utility model 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 the technical solution of the utility model, when the windward side of blade I and blade IV are contacted with wind-force, at this point, leaf Piece II, blade III leeward contacted with wind-force, blade II, blade III will generate negative torque, in order to avoid negative torque It generates, controller controls steering engine movement corresponding with blade II, blade III, so that the swing arm of the two steering engines be made to put upwards Dynamic 90 ° are generated electricity by turned to plumbness, blade I and blade IV, when blade IV rotates counterclockwise 90 ° of positions to 1/2 π When, the leeward of blade IV is contacted with wind-force, and controller controls the corresponding steering engine movement of blade IV, to make the pendulum of this steering engine Arm is swung up 90 ° to plumbness, and at this point, blade II rotates counterclockwise 90 ° of positions to 3/2 π, the windward side of blade II Start to contact with wind-force, controller controls the corresponding steering engine movement of blade II, to make the swing arm of this steering engine to 90 ° of lower swing Wind-force is born to horizontality and generates torque, is so recycled, when blade turns at 1/2 π, the swing arm of corresponding steering engine is put upwards 90 ° are moved to plumbness, to avoid the generation of negative torque；Meanwhile when blade turns at 3/2 π, the swing arm of corresponding steering engine to 90 ° of lower swing are born wind-force to horizontality and generate torque.The utility model not only starts wind-force and is down to 2-3 grades by 4-5 grades, greatly A year generating dutation is increased greatly；And revolving speed can be improved under same wind-force to avoid the generation of negative torque, promote power generation function Rate greatly promotes the generating efficiency of 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.
