Description
Technical field:
This utility model relates to technical field of wind power generation, particularly to a kind of small-sized wind power generator.
Background technology:
Owing to wind-driven generator is operated in natural environment, the running parameter such as wind direction, wind speed is entirely change at random, scope
The biggest.General big-and-middle-sized wind power generator incorporated in power network is provided with perfect control device, it is ensured that the normal work of wind-driven generator
Make and the machinery of self, electrical safety.These servosystems are mainly made up of following system module: 1. synchronize system: use
In frequency, phase place, keep consistent in the voltage x current ensureing wind-driven generator output with the voltage x current of electrical network.2. servo system
System: include that the brake of head horizontal circle week Rotable Control System, blade angle control system, circumference spin brake system, main shaft is
System, blade angle holding system etc..3. sensing system: include that wind direction and wind velocity integrated transducer, various mechanical location sense
Device, attitude transducer, pressure transducer, liquid level sensor etc..These apparatus structures are complicated by special compliant tube Ore-controlling Role
Management work, involves great expense, accounts for more than half of whole wind-driven generator cost.
General individually or the small-sized wind power generator that runs of off-network, be limited to cost be the rearmounted empennage of head mostly for
Finding wind direction, fixed blades, generator shaft rotating speed is uncontrollable, and output voltage changes with wind speed change.Run into strong wind or need
When to be stopped manually or semi-automated mechanism change direction hide public attention.Even if work the most in a secure environment
Making, if running into underloading or the slightly larger driving output voltage that also there will be of wind speed drastically raises, under extreme case, there is also flashover
The problem of the equipment such as discharge breakdown rectification, inverter.Owing to there is the above defect, limit wind-driven generator to wind speed and wind
The scope of application of power, reduces the utilization rate to wind energy.The disconnected blade simultaneously caused by resonance, disconnected tower bar bracing wire and tower bar are toppled over
Also happen occasionally.
And the air velocity transducer of existing small-sized wind power generator and wind transducer are arranged on head, after blade
Square, blade is first blown in this design due to wind, just can be through air velocity transducer and wind transducer after being decelerated, to detect
Data can cause error, and additionally wind can cause turbulent flow, the error that turbulent flow is caused also superposition to enter to make through the blade rotated
Detection accuracy is lower.
Summary of the invention:
In consideration of it, be necessary to design a kind of small-sized wind power generator.
A kind of small-sized wind power generator, including: pylon, head, blade, worm-gear speed reducer, motor, axial compressive force
Bearing, wind transducer, air velocity transducer, Hall element, magnet steel, single-chip microcomputer；Wherein, axial compressive force axle is passed through in head bottom
Holding and rotate fixing with tower top, head front portion rotates and is fixed with blade, and worm-gear speed reducer, motor are arranged on pylon
Portion, motor is connected with head power by worm-gear speed reducer；Around head on the pylon pylon with head junction
Rotary shaft (axis that i.e. head rotates relative to pylon) be evenly equipped with one week Hall element, at the machine of pylon Yu head junction
Being provided with magnet steel at Tou, magnet steel is suitable so that the Hall element that magnet steel can be closed on detects with the distance of such rotation axle；?
On pylon and be positioned at below blade windward side and be provided with wind transducer and air velocity transducer；Wind transducer, air velocity transducer,
Hall element, the holding wire of motor are connected with single-chip microcomputer, by the wind direction detected in real time, wind speed, current vane windward
Angle, whether Single-chip Controlling motor starts to change blade Windward angle.
Preferably, Hall element is 12.
Preferably, small-sized wind power generator also includes accumulator, voltage sensor；Voltage sensor is arranged on accumulator
On, voltage sensor is connected with single-chip microcomputer.Motor is dc motor.
This utility model can allow head at tower bar by using the motor-driven worm-gear speed reducer of small power DC
Horizontal circle Zhou Xuanzhuan is made on top, allows generator blade windward side be directed at wind direction when normal work, avoids wind direction when quitting work.
Worm-gear speed reducer simple in construction, no-load voltage ratio are big, and the frame for movement of itself just determines it has well machinery position and stop
Car function, eliminates a set of brake gear, reduces manufacture and maintenance cost.Head horizontal rotation circumference sets every 30 degree
Putting a Hall element, it is the most accurate that the judgement of head rotational angle can be accomplished by combination algorithm.
