Abstract
The invention discloses a pneumatic power adjusting device for a wind power generator set with a vertical shaft, comprising a blade type power adjusting sheet 5. The pneumatic power adjusting device has the advantages of overcoming the technical problems of bad natural property and difficult brake of the prior wind wheel, improving the output properties of the Darrieus wind wheel, obtaining more annual generated energy and simultaneously improving the braking performance of Darrieus wind wheel.
Description
Technical field
The present invention relates to the pneumatic power controlling device that a kind of vertical axis aerogenerator group is used.
Background technique
At present, the capital equipment of wind-power electricity generation has two kinds, horizontal axis wind-driven generator group and vertical axis aerogenerator group, and the equipment of structural type, operating conditions and the employing of this two classes unit is incomplete same.The blade of horizontal shaft wind-power unit is around the horizontal rotational shaft that is parallel to ground, by widespread usage in wind-power electricity generation.The blade of vertical axis wind electric unit winds the vertical pivot rotation perpendicular to ground, and typical vertical axis wind electric unit is the Darrieus type.Darrieus in 1931 at U. S. application patent (patent No. 1835018), a kind of vertical axis wind electric unit has been proposed.A large amount of vertical axis wind electric units has appearred abroad in the 80-90 age in last century, and has developed the Darrieus wind-powered electricity generation unit of 4 megawatts.
The output power of Darrieus wind wheel will increase with the increase of wind speed, the output of wind wheel nature stall will minimizing wind wheel behind certain wind speed, this is the natural characteristic of wind wheel, Darrieus type vertical axis wind electric unit is because the mounting type of blade, be difficult in the practice regulate the angle of attack that changes blade, can only utilize the natural characteristic of wind wheel.There are 2 distinct issues in the Darrieus wind wheel: the one, be difficult to obtain suitable natural stalling characteristics in the Darrieus type wind wheel practice; The 2nd, Darrieus type wind wheel rotary inertia is very big, and brake percentage is difficulty, need brake by means of resistance of air.Existing product and technology also do not have to solve above-mentioned 2 distinct issues.
Summary of the invention
The pneumatic power controlling device that a kind of vertical axis aerogenerator group provided by the present invention is used, its structure comprises blade profile power adjustments sheet 5.
Its structure of pneumatic power controlling device of the present invention can also comprise motor 1, gear-box 2, drum type coupling 3, live axle 4, coupling 6, bearing and the bearing support 7 of band brake; Wherein blade profile power adjustments sheet 5 is fixed on the live axle 4, the two ends of live axle 4 are installed in the stull of vertical axis wind electric unit by coupling 6 and bearing and axle bush seat 7, and live axle 4 is through the motor 1 of drum type coupling 3 connection gear casees 2 and band brake.
Blade profile power adjustments sheet 5 sections of the present invention adopt the blade profile of circular shape, and as shown in Figure 3, its section is the cross one another part of the circle of two equal diameters, and such blade profile section is parallel during with the incoming flow air at the string of a musical instrument, and the resistance that air forms is less.When such blade profile power adjustments sheet is used at the Darrieus of 1500kW type wind wheel, only need 3, every length is 10m, and thickness is 400mm, chord length is 1400mm, and power characteristic and braking ability that such blade profile power adjustments sheet can improve wind wheel greatly are installed.
The motor 1 of band brake of the present invention drives 5 upsets of blade profile power adjustments sheet by gear-box 2, drum type coupling 4.
Pneumatic power controlling device of the present invention adopts the less blade profile of resistance of air to make power adjustments sheet 5, be installed in the horizontal support of Darrieus type wind wheel (as shown in Figure 2), the power adjustments sheet is not opened during generating state at ordinary times, the power adjustments sheet is opened 1 angle under certain wind speed, produce certain resistance of air, cut down certain wind wheel power, the power adjustments sheet is all opened when braking, helps the braking of wind wheel.Pneumatic power controlling device of the present invention has overcome that existing Darrieus type wind wheel natural characteristic is bad, braking difficulty technical problem, improve the output characteristics of Darrieus type wind wheel, obtained bigger annual electricity generating capacity; Improved the braking ability of Darrieus type wind wheel simultaneously.

Embodiment
The pneumatic power controlling device that a kind of vertical axis aerogenerator group is used, its structure comprise motor 1, gear-box 2, drum type coupling 3, live axle 4, blade profile power adjustments sheet 5, coupling 6, bearing and the bearing support 7 of band brake; Wherein blade profile power adjustments sheet 5 is fixed on the live axle 4, the two ends of live axle 4 are installed in the stull of vertical axis wind electric unit by coupling 6 and bearing and bearing support 7, and live axle 4 is through the motor 1 of drum type coupling 3 connection gear casees 2 and band brake.
As shown in Figure 3, the resistance of air when move this moment down with the wind was very not little when blade profile power adjustments sheet 5 was not worked; The motor 1 of band brake drives 5 upsets of blade profile power adjustments sheet by gear-box 2, live axle 4 during work; Blade profile power adjustments sheet 5 has rotated 1 small angle, and the operation of facining the wind will produce resistance of air, as shown in Figure 4; 5 rotations of blade profile power adjustments sheet are opened bigger angle and will be produced bigger resistance of air, can cut down the output power of wind wheel with this, as shown in Figure 5; Blade profile power adjustments sheet 5 rotate to vertically-supplying air to the position, i.e. the limit position of blade profile power adjustments sheet 5 produces maximum resistance of air, and the rotating speed of wind wheel is descended rapidly, is used for the braking under the strong wind situation, as shown in Figure 6.
