At.This wind-driven generator is to the more demanding of wind speed, it is necessary to it could work higher than certain wind speed, the electricity of common generator output
Energy frequency is indefinite, is converted to the alternating current higher cost being able to use.Moreover, conventional wind power generator adjusting is more difficult, therefore
Wheel blade damage rate is high, causes maintenance cost high.
Utility model content
Technical problem to be solved by the utility model is: overcoming what conventional wind power generator cannot generate electricity at low wind speeds to ask
Topic, solves the problems, such as that the frequency of conventional wind power generator output electric energy is unstable, and solves common generator control control difficulty
The problem of.The utility model provides a aerofoil profile wind-driven generator based on single pendulum, this kind of wind-driven generator utilizes simple pendulum device
Energy storage characteristic and resonance characteristic, at low wind speeds constantly storage wind energy, achieve the purpose that generate electricity at low wind speeds, together
When, since the period of simple pendulum device is only related with pendulum length, so the frequency of the novel wind generator output electric energy is fixed, very well
Solve the problems, such as that conventional wind power generator is inoperable at low wind speeds, solve conventional wind power generator generation frequency not
Stable problem.Moreover, because the lift coefficient of aerofoil profile can be changed by adjusting angle of attack size, and therefore, the utility model
It can be very good to adapt to various wind speed, blade is less likely to be damaged, and maintenance cost is low.
The technical solution of the utility model includes:

Transfer the change angle of attack.
The usefulness of the utility model: the aerofoil profile wind-driven generator of the utility model can use single pendulum for low wind speed
Wind energy stores, and drives electrical power generators by resonant interaction.The low wind speed energy successfully utilized, makes wind-driven generator
Frequency remain unchanged.And adaptation high wind speed ability is strong, and blade is less likely to be damaged in high wind speed situation.
Detailed description of the invention

In figure: 1 aerofoil profile blade；2 aerofoil profile pitch control devices；3 generator cabins；4 pedestal bars；5 connect pedestal；6 single pendulums
Weight；7 single wobbling poles；8 generator drive shafts；9 airfoil support axis.
Specific embodiment
Below in conjunction with attached drawing and technical solution, specific embodiment of the present utility model is further illustrated.
In Fig. 1, a kind of aerofoil profile wind-driven generator based on single pendulum, including aerofoil profile blade 1, aerofoil profile pitch control device 2, hair
Motor cabin 3, pedestal bar 4, even pedestal 5, single pendulum weight 6, single wobbling pole 7, generator drive shaft 8 and airfoil support axis 9.
Aerofoil profile blade 1 can do the rotation of certain angle around airfoil support axis 9, and aerofoil profile pitch control device 2 is used to control
The wing and the rotation of cabin type blade 1 are to change the angle of attack.Single wobbling pole 7, airfoil support axis 9 are fixed in one with generator drive shaft 8 respectively
It rises.Generator in generator drive shaft 8 and generator cabin 3 is fixed together, and generator cabin 3 is fixed on pedestal bar 4,
In 4 company's of being fixed on pedestal 5 of pedestal bar, single pendulum weight 6 and single wobbling pole 7 are fixed together.
When the generator works, since the period of single pendulum is determined that we determine the period of this generator first by its pendulum length,
The time for setting the rotation of aerofoil profile pitch control device 2, make the angle of attack windward of aerofoil profile blade 1 before the deadline positive and negative
Between change, since the lift coefficient of aerofoil profile is very big, aerofoil profile blade 1 can produce very big active force, pass through 9 He of airfoil support axis
Single wobbling pole 7 constantly fills energy to single pendulum weight 6, and since the angle of attack variation period of aerofoil profile is consistent with period of single pendulum, makees in addition
It firmly resonating with single pendulum, keeps the amplitude of single pendulum increasing, the energy stored in single pendulum weight 6 is more and more, in this way,
In the case where wind-force very little, aerofoil profile wind-driven generator can also work power generation.Equally, when wind speed is very big, by adjusting the angle of attack, subtract
Small lift coefficient keeps the amplitude of single pendulum weight 6 excessively inviolent, makes aerofoil profile blade 1 be unlikely to destroy, ensure that structure in this way
Safety.
