Description
Technical field
The invention belongs to wind-driven generator, relate to a kind of passive variable pitch control and multiblade wind wheel device.
Background technique
The wind wheel of wind-driven generator is divided into initiatively feather control and passive variable pitch control up to now.The feather height of controlling cost initiatively, with high content of technology, the effect in real work is not very good again, but very universal; Passive variable pitch control is to substitute initiatively feather control in the power-limiting mode, and its thinking is that the hub design with blade or blade becomes to reverse under the effect of blade loading, so that obtain required propeller pitch angle under high wind speed.
Among all links of wind-power electricity generation, wind wheel is power plant, is a crucial ring, and what kind of wind wheel to make fan blade present best wind-engaging angle with is problem to be solved by this invention.
With a kind of power plant of wind wheel,, must solve and steadily utilize wind energy under the different wind speed and improve Wind Power Utilization efficient limiting value two big problems in the face of natural wind energy as power generation system.
(1), steadily utilizes wind energy under the different wind speed
It is exactly unstable that wind has a very big weakness.Because air-flow is fast changing, so the pulsation of wind, diurnal variation, season crackization be so that year border changes all fairly obviously, and it is very big fluctuate, extremely instability.Decide paddle sheet its nature with the wind, be difficult to accomplish the constant speed of facining the wind; Become the paddle sheet and control complexity, the blade displacement lags behind wind speed to be changed, and same can not accomplish constant speed down with the wind.Therefore, how solving and steadily utilize wind energy under the different wind speed, is exactly first problem that the present invention will solve: i.e. passive variable pitch control wind wheel apparatus.
(2), improve Wind Power Utilization efficient limiting value
How to make fan blade absorb wind energy to greatest extent, make wind energy transfer kinetic energy to, have only the increase blowing area, could improve the limiting value of Wind Power Utilization efficient.
Summary of the invention
Passive variable pitch control and multiblade wind wheel device are at wind turbines rotor wheel hub sleeve place circular hole to be set, and in the wheel hub sleeve intubate are set, and the intubate place is provided with pin, forms positive tooth.The blade axle tube place is provided with penetrating tilted slideway, forms cloudy tooth.Blade axle tube is inserted wherein, pin is inserted intubate and blade axle tube place are set in the wheel hub sleeve are provided with in the penetrating tilted slideway and take root.Pressure spring is inserted in the blade axle tube, withstand spring the gear screw being screwed into blade axle tube bottom.At last with radiation fluted disc engaging gear screw.When calm, the plate that withstands pressure of the spring in the blade axle tube makes fan blade be the maximum angle of facining the wind.Light air promptly can start, and gentle breeze promptly can generate electricity.When meeting wind, wind wheel rotates, and is reaching certain wind speed, and centrifugal force whipping blade, blade axle tube outwards stretch along ramp angle spring is under pressure, the blade translation-angle, thus form needed propeller pitch angle.Radiation fluted disc engaging gear screw plays and makes the blade synchronization angle, to increase stress.
The present invention for achieving the above object, by the following technical solutions: wind wheel type multi-vane wind power generator comprises vertical rod, generator and wind wheel wheel hub covering device, blade axle tube device and radiation fluted disc device.It is characterized in that: describedly circular hole is set at wind turbines rotor wheel hub sleeve place; Describedly intubate is set in the hub sleeve at wheel; The described shaped as pin Chengyang tooth that is provided with at the intubate place; Describedly penetrating tilted slideway is set, forms cloudy tooth at the blade axle tube place; Described the fan blade central siphon is inserted wherein; Described pin is inserted is provided with intubate and blade axle tube place and is provided with in the penetrating tilted slideway and takes root in the wheel hub sleeve; Described pressure spring is inserted in the blade axle tube, withstand spring the gear screw being screwed into the blade axle tube bottom; Described with radiation fluted disc engaging gear screw.Beneficial effect: this wind-driven generator can utilize light air startup, breeze wind.Wind speed is crossed very much not and is exceeded the speed limit, need not shut down.Three traditional blade wind-powered electricity generation machine mounting structures have been changed, adopt passive variable pitch control and multiblade wind wheel device, make wind wheel along with the size of wind-force is utilized the automatic adjusting angle of centrifugal force, utilize stall to regulate rotating speed automatically, thereby increase substantially utilization ratio and the limiting value that increases substantially Wind Power Utilization wind energy.

Embodiment
Describe embodiments of the present invention in detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of passive variable pitch control and multiblade wind wheel device structural representation one insert figure one-2,4,5 with blade axle tube figure three-2; Advance pin figure one-3; Insert spring figure one-11; Tighten gear screw figure one-8; Put fluted disc figure one-9 and gear screw engagement.Blade axle tube outwards stretches at action of centrifugal force lower edge blade axle sleeve jack, and the resistance pin makes blade form needed propeller pitch angle along angle slideway picture three-3 compacting springs of blade axle tube, reaches the best wind-engaging attitude of fan blade of setting.When calm, blade is on the maximum wind-engaging angle.When meeting wind, wind wheel rotates, and centrifugal action is on blade when reaching certain rotating speed, and spring stress compresses, and blade forms best wind-engaging angle along the central siphon slideway, and wind wheel increases rotating speed.When the wind speed increasing, when fan blade angle forwarded to more than 55 °, wind speed round descended, and blade centrifugal force reduces, and spring tension moves angle and diminishes greater than centrifugal force in the blade angle, increase blowing area.The swing of each sheet fan blade is all the time under the effect of spring, pin, under the angle of central siphon slideway regulation, under the effect of synchronizer, along with the natural wind of different stage presents best wind-engaging attitude.
The above only is preferred embodiment of the present invention, is not its structure is done any pro forma restriction.Every foundation technical spirit of the present invention all still belongs in the scope of technological scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
