The present invention is done further preferably, first grade blade, second grade blade, the third level blade, institute
It is to meet aerodynamic winged petiole to state fourth stage blade and the level V blade.
Compared with prior art, the present invention has following beneficial effect：
The wind wheel in the present invention includes rotor shaft and blade support, and the central part of the blade support both sides passes through method
Orchid is arranged on the both ends of the rotor shaft, is so formed and is symmetrically installed, stability is good.The present invention is carried out to existing blade support
Change, the both sides of the blade support form mounting surface, and the mounting surface includes 5 different-diameters, arranged at equal intervals, with one heart
The mounting ring of setting, that is to say, that mounting ring is 5, not of uniform size, but is when mounted concentric installation settings at equal intervals, place
In same level, installation is in reinforcement connection by 10 cage bars, general cage bar is arranged on the side of mounting ring, so 5
Individual mounting ring connects into an entirety by 10 cage bars, while 10 cage bars carry out annular array by the center of circle of rotor shaft, this
The purpose of sample is to form a stable blade support；In order to improve the stability of whole wind wheel, between blade support
Set, i.e., connecting rod is provided between blade support cage bar, reinforcing will be attached between cage bar, also in blade support
On mounting ring between be provided with crosspiece, by crosspiece to being reinforced between mounting ring；It is possible thereby to it is good to form a stability
Blade support.
The present invention sets fan blade on blade support, and first is respectively equipped between the adjacent mounting ring on blade support
Grade blade, the second grade blade, third level blade and fourth stage blade, 10 mounting rings are shared on blade support, that is to say, that same
Isodiametric mounting ring is 5 groups, and the first grade blade, the second grade blade, third level blade and the are set in adjacent installation ring group
Four grade blades, wherein the first order blade, second grade blade, the third level blade and fourth stage blade difference
To be arranged on every angle on crosspiece, in other words, the installation site of the second grade blade is between 2 adjacent first level blades, similarly,
For the installation site of third level blade between 2 adjacent second grade blades, the installation site of fourth stage blade is 2 the adjacent 3rd
Between grade blade, the first grade blade is that same is diametrically installed with third level blade, and the second grade blade exists with fourth stage blade
Same is diametrically installed；Present invention additionally comprises level V blade, the level V blade is located in outermost mounting ring, together
When be arranged in the connecting rod between 2 cage bars, this 2 cage bars are respectively on the both sides mounting surface of wind wheel support, and this
Five grade blades are on non-rectilinear and installed with the first grade blade, the second grade blade, third level blade, fourth stage blade；The present invention
Described in the first grade blade, second grade blade, the third level blade, the fourth stage blade, the level V blade
Respectively carry pitch motor；The present invention carries out angle adjustment by pitch motor to blade, and so each grade blade can basis
Wind speed and wind speed round adjustment angle, reach under different wind speed, and lift is maximum, and resistance is minimum.
Blade in the present invention has 25, i.e., the quantity of described first grade blade, the quantity of second grade blade, described
The quantity of third level blade, the quantity of the fourth stage blade, the quantity of the level V blade are all 5；It is so of the invention
25 fan blades are shared on wind wheel, by the setting to pitch motor, are rotated in certain limit, such control fan blade is just certain
Angle rotating, when wind come when blowing, fan blade will turn to suitable optimal Windward angle.
Invention increases fan blade frame, while the appropriate fan blade that adds improves rotor solidity, than the increase of the leaf machine of in general three
40% reduces threshold wind velocity and rated wind speed, while fan blade frame makes fan blade shorten, and fan blade intensity increase, wind resistance power improves,
Broadened using wind speed range.Improve wind energy utilization.
It is to adjust different wind speed using the different change oar fan blade of Pyatyi that Pyatyi of the present invention, which becomes oar, under different tip speed ratios
The angle of fan blade not at the same level, to reduce windage of the fan blade in high-speed cruising, windage is reduced, improves wind speed round.Improve
Blower fan benefit.And operating three leaves machine overcomes windage of the fan blade in high-speed cruising, incited somebody to action to improve wind speed round at present
Fan blade top is made sharp and narrow.The present invention sets 5 grade blades, and each grade blade can be according to wind speed and wind speed round adjusting angle
Degree, reaches under different wind speed, and lift is maximum, and resistance is minimum, and this point is that three leaf machines are not accomplished.For example, rotor diameter
For 70 meters of three leaf machines, under fresh gale speed, if wind speed round is 20 revs/min, now tip speed is 70 meter per seconds, from wind wheel
Fan blade speed also has 40 meter per seconds at 20 meters of center, and from wind wheel center, to satisfy gradual change big for the windage of fan blade at blade tip, closer to blade tip
It is bigger to locate windage.Three leaf machine operating principles need to increase fan blade vane angle when being and starting, and to increase the wind area of fan blade, obtain most
Big startup power, fan blade is synchronous up and down during startup, and it will obtain the lift of maximum after startup, make wind speed round most fast, and most
Big lift is in 12 degree or so of vane angle, wind maximum at this point for the area that is obstructed of the fan blade direction of motion for high-speed motion fan blade
Resistance is also maximum, and blade is just asynchronous up and down, and this is conflict, and three leaf machines are to sacrifice blade top area to reduce windage,
So it is more up made more sharp narrower.And the present invention solves this problem well.
The present invention, than more fan blade frames, adds certain windage, but be the increase in wind wheel frame to make whole wind with three leaf machines
Out-shift of gravity center is taken turns, the inertia of wind wheel increases, and the operating of wind wheel is more steady in the presence of inertia.25 fan blades are arranged on not
With angle and different sections, distribution is more reasonable, and the influence of fitful wind and survey wind to wind wheel reduces, and this is also that three leaf machines can not be done
Arrive.
Turbine effect is reduced to minimum by the present invention, and normal conditions, wind wheel blade is more, and fast ratio is lower between leaf, and influences
Fast ratio also has turbine effect in addition to blade profile between leaf.It is although and other more and wind wheel blade of the present invention is more than three leaf machines
Leaf machine is different, and the present invention is using the lift-type winged petiole for meeting power principle.Because blade shortens, and mal-distribution is in difference
Direction and different sections, turbine effect influence it is relatively small.
The present invention significantly reduces manufacture, transport, installation cost, and the requirement to highway reduces, and safeguards and maintenance is more square
Just, wind energy utilization of the present invention is high in addition, requires low to wind field wind speed, and influence of the wind field scale to cost is small, investment pressure
Power is relatively light.The present invention is more suitable for the bad mountain area of Highway Conditions.
From the foregoing, it will be observed that the present invention can solve the problem that deficiency of the prior art, the device adds fan blade, adds wind wheel reality
Degree, reduces blower fan threshold wind velocity, reduces wind field condition, is classified by Pyatyi and becomes oar, meets blade in different layers, different wind
Tune oar requirement under speed, fan blade shorten, and reduce manufacture transport installation difficulty, alleviate cost, realize more preferable wind-power electricity generation.
