Description
Technical field
Patent of the present invention is related to a kind of wind power utilizing device field
Background technology
The Universal Windmill (201210393482.2) of paddle length is adjusted by stent, leaf paddle, leaf paddle head, end plate, shaft, paddle length control
A few part compositions of system.2~4 leaf paddles are evenly distributed on around shaft, and leaf paddle is diagonally-installed on stent by leaf paddle head, shape
Into V-shaped structure, the gradient (α), the degree of eccentricity (β), installation of leaf paddle can be adjusted using three respective axes of rotation on leaf paddle head
The angle of attack (γ), wherein：The angle of leaf paddle spanwise axis and horizontal direction is defined as leaf paddle gradient (α), is represented with angle；Leaf paddle
Pressure line and shaft between the ratio of deviation distance and its maximum deviation distance be defined as the degree of eccentricity (β), with percentage table
Show；The aerofoil profile string of a musical instrument and the angle of horizontal direction are defined as the installation angle of attack (γ) when windmill is static, are represented with angle.Adjust leaf paddle head
On three shafts, the gradient (α) of leaf paddle, the degree of eccentricity (β), the installation angle of attack (γ) is changed, just cut leaf paddle type
Direction, the position in face are changed, so that the direction of the lift produced on leaf paddle aerofoil section and size change.It is logical
Cross optimized design and adjusting, so that it may so that after windmill starts rotation under wind-force effect, as rotary rpm is continuously increased,
Make the linear velocity of leaf paddle leading edge increase, this is added since Windmill rotary produces again equivalent to the natural wind that leaf paddle leading edge is subject to
Wind-force, realize be output to input between feedback.Again since leaf paddle is diagonally-installed on stent by leaf paddle head, V is formed
Character form structure, and have certain degree of eccentricity (β), the feedback signal of lift-type windmill is strengthened original after being superimposed with input signal
The input signal come forms positive feedback, so that the turning moment increase that windmill is subject to, the increase of windmill rotating speed, and feed back to defeated
Enter end and generation positive feedback effect is superimposed with input signal, improve windmill efficiency.
Windmill improves wind energy conversion efficiency with positive feedback effect, while also solves lift vertical shaft windmill and be unable to oneself
Starting problem.But wind energy is the extremely unstable energy, wind speed, wind are strong, wind direction all constantly varies anywhere or anytime,
This not only carrys out very big difficulty to the zone of transformation of wind energy, and gives follow-up receiving application, also result in very big unfavorable conditions.Make
Obtain wind electricity digestion hardly possible, abandon the phenomenons such as wind problem is serious, wind energy utilization is low, become existing emphasis during China's Wind Power Development
Problem, is not solved effectively also at present
The conventional wind generator of existing wind power technology in order to network with it is safe for operation, the general method using tune pitch come
The power output or rotating speed of windmill are adjusted, but this control is very undesirable, or even do not reach expected purpose at all.By adjusting
Pitch, to the blade angle of attack is adjusted, then to power coefficient, then to output power, this control process was both unreliable, also unstable,
Do not reach the power output of stable windmill or the purpose of rotating speed at all, the security of windmill will not be risen in technical elements more
Big guarantee effect.There are some output power this characteristics directly proportional to blade wind sweeping area according to windmill in recent years, if
Want to increase wind sweeping area with the method for increase length of blade, to reach increase output power, produce the purpose of more energy,
The stacked air vane that is nested of length of blade can be changed by devising, it is desirable to which one kind is provided under low wind speed condition can produce greatly
Measure the big wind wheel of the energy；And length of blade can be shortened under the conditions of high wind speed, limit mechanical load, it is defeated that formation can reduce power
The small wind wheel gone out, it is expected to solve in such a way because natural wind is suddenly big or suddenly small and caused by output it is unstable, generator is not
Can running at full capacity, and the problems such as low-voltage cannot pass through, it is no longer so-called " rubbish is electric " to make the electricity that windmill is sent, no longer
Very big impact is caused to power grid.Such as：WO 2003102414Al VARIABLE LENGTH TURBINE BLADE；
The patents such as P2005-188428A.But above mentioned patent is all blade applications by that can change length in trunnion axis spiral shell
Paddle windmill is revolved, idea is although good, can be due to the special tectonic of horizontal axis propellers windmill, and the inadaptable leaf that can change length
Piece, so above patent does not obtain significant technological progress, even without specific implementation and is promoted.
The telescopic wing of length can be changed to solve to network by adjusting the Universal Windmill (201210393482.2) of paddle length also to apply
With problem safe for operation, because the special tectonic of Universal Windmill is extremely matched with that can change the telescopic wing of length, both mutually auxiliary phases
Into, perfect pair, so, the application of patent of the present invention, will be that wind power technology brings significant technological progress.
The content of the invention
First, the structure of telescopic wing
A kind of telescopic wing for the Universal Windmill for adjusting paddle to grow is by three sections of essentially identical aerofoil profile leaf paddle section groups with camber of construction
Into every section of leaf paddle intersegmental part is designed with pulley, track, steel wire rope, ball, spring etc., and the elevator that control leaf paddle stretches is arranged at bottom
Machine；Three sections of aerofoil profile leaf paddle sections are nested and stack, and all bottom passes through connecting rod (or connecting plate) to every section of leaf paddle section inside it
One section of track parallel with leaf paddle segment length direction and that length is suitable with leaf paddle segment length is connected with, what three sections of leaf paddle sections were connected
Three sections of tracks determine the lateral position of leaf paddle section by roller and carry out the slip of length direction；When the volume in first layer bottom
When raising machine and pulling by steel wire rope (or withdrawal) second layer track and the leaf paddle section to rise (or landing), the track and leaf paddle section of rise
(or withdrawal) adjacent third layer track is jacked up at the same time further through pulley and steel wire rope and leaf paddle section rises (or landing), with such
Push away, extend to multistage, leaf paddle is achieved that Telescopic.
Interorbital pulley reduces the friction simultaneously lateral position of trapped orbit and aerofoil profile leaf paddle section, and determines between every section
The nested amount of minimum；Reduced between leaf paddle with ball and rubbed, and played a supportive role；
Three sections of aerofoil profile leaf paddle section shapes and cross section fundamental form are same, are the airfoil type with camber, for three sections of leaf paddle section energy
It is nested together, the first layer leaf paddle section of outermost is than bigger several millimeters of the exterior contour of second layer leaf paddle section, and the second layer is than the 3rd
Bigger several millimeters of layer, and so on, extend to multistage.End plate is housed at the top of innermost layer leaf paddle section.
2nd, the characteristics of telescopic wing
Formed since telescopic wing is nested to stack by three sections of aerofoil profile leaf paddle sections, and shape fundamental form is same,
For the airfoil type with camber, so whole leaf paddle can produce lift, and have positive feedback effect no matter in elongation and shortening
Should.When wind-force is smaller, and windmill cannot produce more power outputs, just extend leaf paddle, this not only adds windmill wind sweeping area
Greatly, the wind energy of capture increases, and increases output power, and efficiency also improves.On the contrary, larger in wind-force, output power will be super
When crossing generator rating power, just shorten leaf paddle, reduce the wind energy of leaf paddle capture, reduce power output, prevent wind-power electricity generation
Machine damages, and ensures that windmill output is steadily and safe for operation.
In telescopic wing, due to applying substantial amounts of roller, ball and bearing, leaf paddle section and interorbital not only ensure that
Relative position, and motive power is support, leaf paddle is easily stretched, the also control to telescopic wing creates very
Good condition, improves controlled device characteristic, and control is sensitiveer more accurate.
Whole telescopic wing is supported mainly by internal track and shell, most of since leaf paddle tilts upward
Gravity by rail effect on chassis overhang, as long as so bear the motive power on leaf paddle with general material,
And it is unlikely to cause leaf paddle to fracture.
3rd, telescopic wing automatically controls
Telescopic wing can be with according to different needs, different environment, different application, with wind speed, output power, environment temperature
Degree, leaf paddle extension position detector are engaged, using different control strategies, such as：The control of PID fits automaticallies, manually control,
Self adaptive control, remote control, programme-control etc., can also carry out intelligent control.
It is known that wind power P=1/2vs ρ v2=1/2s ρ v3=0.6sv3
ρ is ρ=1.2928kg/m under atmospheric density standard state3, it is contemplated that this place calculating of the factor such as temperature take ρ=
1.2kg/m3, s is windmill wind sweeping area, and v is wind speed.
By in formula as it can be seen that wind power is directly proportional to wind sweeping area, it is directly proportional to the cube of wind speed.
For two leaf paddle vertical axis windmill of V-shaped structure, wind sweeping area is with the isosceles triangle of a length of length of side of paddle
Area, according to triangle area formula, can obtain：
Wind sweeping area=R2sinαcosα
Wherein R grows for paddle；α is angle of inclination；
It can thus be seen that V-shaped structure make that wind sweeping area and paddle grow it is square directly proportional.So, paddle is grown very
Small change, the very big change with regard to that can obtain wind sweeping area, the effect that this just grows adjusting paddle is more preferable, sensitiveer.
Automatic control system signal flow block diagram is as shown in Figure 6.
