Description
Technical field
The utility model intelligent high-power windmill is by 3 or many vertical shaft windmills that intelligent blade is formed.Experimental results show that: the intelligent high-power windmill will greatly improve the efficient of existing windmill, and can improve the total output of separate unit windmill exponentially.The intelligent high-power windmill will bring the technological revolution and the progress in a pneumatic power field.
Background technique
China is populous, relative inadequacy of resources, and many valuable source occupancy volume per persons are far below world average level.China's oil resource ultimate recoverable reserves only is about 3% of world's total amount; the non-renewable resources reserves constantly reduce; the contradiction of economic development and resource, environmental protection becomes increasingly conspicuous, and the challenge of reply energy security is one of China's STRATEGIES OF SUSTAINABLE DEVELOPMENT emphasis.In renewable resources, wind energy content is abundant.Development and utilization to wind energy is very important, and still, the utilization ratio that how to improve wind energy is the important topic of confronting.
The present vertical shaft windmill that uses is because blade can't reduce blade and drive resistance coefficient against the wind, thereby windmill efficient is too low, fails to be promoted the use of widely when not doing work against the wind.And the intelligent high-power windmill not only successfully will not do work the time the former reduced cross-sectional area of blade become wire, greatly reduce blade to drive resistance coefficient against the wind the efficient of the windmill list group blade acting that has been multiplied; Simultaneously, the intelligent high-power windmill can increase the combination of blade or blade commentaries on classics group in the vertical and substantially horizontal of wind turbine tower bar, can improve the total output of separate unit windmill ultra-largely.
Summary of the invention
In order to overcome the deficiency of prior art structure, the utility model provides the intelligent high-power windmill.
The utility model intelligent high-power windmill has following technical characteristics:
The intelligent high-power windmill is an intelligent vertical shaft type windmill, is made up of 3 or many intelligent blade, and the air vane bottom surface is movable, and the bottom surface upper limb is provided with hinge and is connected with the lower edge of blade frame; Also can with top rotatingshaft be set in 1/2 of movable bottom surface, movable bottom surface can unidirectionally upwards be stirred near 90 degree, and it only allows, and air-flow is unidirectional to be passed through.
When blade did work down with the wind, the bottom surface can be close to the edge bottom frame automatically, made the maximization of acting section area, realized maximum output; When blade did not do work against the wind, nearly 90 degree can upwards be stirred in movable bottom surface under the effect of wind-force, allow air communication to cross blade frame.Therefore, the former reduced cross-sectional area of blade becomes wire when not doing work, and has greatly reduced C when not doing work
T2Resistance coefficient, thereby the efficient of the windmill list group blade acting that has been multiplied.
Vertical and substantially horizontal at the wind turbine tower bar increases blade commentaries on classics group and makes up, and can improve the total output of separate unit windmill ultra-largely.
The intelligent high-power windmill can be provided with the flywheel of one or more different radiis in order to overcome the influence of caused aerodynamic loading of blade cyclically-varying and vertical shaft discontinuity on vertical shaft.
The windmill moving vane of intelligent high-power windmill and framework surface of contact are provided with the vibration damping rubber-plastic strip of being with groove, and perhaps other vibration damping facility reduces noise.
The blade acting stress surface of intelligent high-power windmill is designed to coarse surface, to have increased the efficient of blade acting; The back side is designed to smooth surface, the resistance when not doing work to reduce blade.
The intelligent high-power windmill can change acting vane stress area automatically by wind-force.When doing work down with the wind, blade can be deployed into maximum area automatically, realizes maximum output; When not doing work against the wind, blade can dwindle into wire with original area automatically by wind-force, thus the efficient of the windmill list group blade acting that has been multiplied.Simultaneously, the intelligent high-power windmill can increase the combination of blade or blade commentaries on classics group in the vertical and substantially horizontal of wind turbine tower bar, can improve the total output of separate unit windmill ultra-largely.
According to the newborn work of " Wind Power Utilization technology " Guo, publish " Chemical Industry Press " in May, 2007.The Wind Power Utilization technology is made following clearly statement:
" available wind energy in theory:
Vertical current is crossed the air of cross section F in unit time, and the ability of the acting that has is called the power of wind energy (W):
W=1/2p?Fv

Wherein: air density is that p, speed are that v, sectional area are F,
Wind energy E=1/2pFtv

Be illustrated in the wind energy that flows through cross section F in the time t.
Cube being directly proportional of the size of wind energy power and wind speed also crossed area with the density of moving air and vertical current and is directly proportional.”——23p
Wind energy conversion system can make horizontal shaft type with perpendicular axis type, blade can adopt lift-type or resistance blade profile,---29p
In vertical shaft fan, resistance difference type blower fan:
" if blade shape with the wind with upwind time of vertical axis windmill is different, then air-flow acts on the resistance of blade on two directions, and greatly different difference is just arranged, thereby windmill is rotated smoothly.
With vane formula wind gage:
If the linear velocity of moving in wind speed in the blade center is u, when wind acts on the concave surface of vane hemisphere, drives resistance with the wind and be: T
1=1/2pC
T1F (v u)

Driving resistance against the wind is: T
2=1/2pC
T2F (v+u)

V is in wind speed, the formula: C
T1, C
T2Be respectively cup-shaped blade concave surface with the wind, the resistance coefficient of the convex surface that facings the wind: hemisphere vane C
T1Can reach 1.33, and C
T2Value only be 0.34;
The power P of vane formula wind energy conversion system
P=1/2pF[C

The intelligent high-power windmill is an intelligent vertical shaft type windmill, can change acting vane stress area automatically by wind-force, and when doing work down with the wind, blade can be deployed into maximum area automatically, realizes maximum output; When not doing work against the wind, blade can dwindle into wire with original area automatically by wind-force, thus the efficient of the windmill acting that has been multiplied.
Obviously, the blade of intelligent high-power windmill drives the C of resistance coefficient against the wind
T2Value can be more less than 0.34; Here, the blade of establishing the intelligent high-power windmill with the wind during the concave surface acting area be F, area was not n/one of F owing to dwindle into linear when the convex surface that facings the wind did not do work.
Area after dwindling when convex surface does not do work if facing the wind is f, i.e. nf=F,
Power P formula according to vane formula wind energy conversion system
P=1/2p?F[C
T1(v?u)

F, f are taken advantage of in the formula, following formula can be written as:
P=1/2p[F?C
T1(v?u)
2?fC
T2(v+u)
2]u”
