Description

A kind of vertical axis aerogenerator based on lever principle design
Technical field
The invention discloses a kind of vertical axis aerogenerator based on lever principle design, be a kind of arm of force utilizing telescopic folding be in particular support, drive the vertical axis aerogenerator that fan blade stretches or shrinks. The present invention a kind of utilizes lever principle to be amplified by faint wind-force, utilizes the wind-driven power generator after amplifying to carry out the technology generated electricity.
Background technology:
Wind-power electricity generation is not a kind of new technique, but is as mankind's demand to new forms of energy and increases gradually, and wind-power electricity generation has become as one of 21 century the most popular technology.
The designer of conventional wind generating has been based on the theory of the aerodynamic aspects such as shellfish hereby theory, blade momentum theory and is designed and researches and develops, but these researcheres all have ignored an important parameter leverage:
By Traditional Thinking yoke, wind-power electricity generation researcher is always with aerodynamic for research direction. The impeller diameter of common vertical axis aerogenerator only has several meters, although blade area improves constantly, but power is not obviously improved. Although and horizontal axis wind-driven generator is studied under same guiding theory, but the developing direction of horizontal axis wind-driven generator by chance matches with lever wind-driven generator, therefore obtain certain development.
For common levels axis wind power generator, fan blade length tends to reach tens meters, and blower fan main shaft diameter is usually no more than 1 meter. If fan blade is considered as a lever, a blade 50 meters long is to the minimum enlarge-effect that can provide more than 50 times of wind-force. After blower fan main shaft obtains the big torsion input of the slow-speed of revolution, it is possible to by change speed gear box, big for low speed torsion is turned to the output of high speed torsion, outputting torsion can be utilized afterwards to drive electromotor to generate electricity.
The researcher of vertical axis aerogenerator, in default of correct theoretical direction, causes research direction sideslip, it does not have considered to improve wind energy utilization by increase impeller diameter. Then the development causing vertical axis aerogenerator is had difficulty in taking a step.
Summary of the invention:
The essence of wind energy is a kind of low-density energy. Simple wind energy is not sufficient to pushing generator generating. In order to be sufficiently large mechanical energy by low-density wind energy transformation, the various methods to Wind Power Utilization of man invented. It it is sail or windmill is all that low-density wind energy is put together the solution becoming high density energy.
In order to effectively utilize wind-force to generate electricity, simple increase blade area is not best solution. In order to reach the balance to Wind Power Utilization Yu leverage, I devises and amplifies, with leverage, the solution that wind-force carries out generating electricity. (with reference to ZL201510497988.1 intelligent blade structure for wind driven generator)
According to above-mentioned theory, vertical axis aerogenerator can also be transformed accordingly.Air is considered as in shellfish hereby theory a continuous fluid, and conventional wind generating researcher is confined to the air flowing near wind wheel. And I thinks that wind energy is a kind of low-density range performance source, because air flowing is the flowing of one globality on a large scale. That is once blowing, within the scope of one, integrated air all can flow, and fan blade distance all can be subject to windage at any time. No matter fan blade is at distance 1 meter of of pylon or at distance 50 meters of of pylon, the direction or leeward of no matter being in the wind, and all can be subject to the impact of wind-force. And the fan blade designed based on Bernoulli's theorem also can guarantee that it is no matter positive draft or back draught all can provide power for blower fan.
Therefore, corresponding conventional vertical axis wind power generator, new-type vertical axis aerogenerator should find an equilibrium point between blade area and torque arm length and wind speed round. Fan blade area is more big, and in the unit interval, by wind impact is more big. But during fan blade more big deadweight more Datong District, windage also can be more big, and rotating speed can be influenced by impact then. The blower fan arm of force is more long, it is possible to obtain more big leverage ratio, but the arm of force lengthens and will also result in blower fan deadweight increase. Leverage also results in output speed reduction simultaneously.
The present invention is made up of following part, including: pylon 1, the arm of force 2, driving device 3, blade 4, supervising device 5;
Pylon 1 is vertical axis aerogenerator main support structure, and it primarily serves the purpose of guarantee wind-driven generator steady operation.
The arm of force 2 is the connecting device between pylon and fan blade. Causing the damage of blower fan in order to evade high wind, safeguard for the ease of blower fan, the arm of force 2 can be designed as telescopic folding structure. The arm of force 2 can have multiple different structure, it is possible to is straight-arm structure (see figure 1), it is also possible to be foldable structure (see figure 2) or polymorphic structure. The arm of force can be one, it is also possible to is many and collectively constitutes (see figure 3). In actual applications, the blower fan arm of force can be one, it is also possible to formed by organizing the arm of force more. The structure of the arm of force can also carry out various change as required. It can be a hollow tubular object that the arm of force 2 can freely stretch or shrink (see figure 4) arm structure under the support of pylon 1, or increasing auxiliary inside hollow tubular structures supports beam, or biological skeleton is copied to increase reticular supporting structure inside tubular structure. Arm structure can be include the arbitrarily geometric shape (see figure 5) such as circle, ellipse, hexagon.
According to different wind environment with different build budget and different aesthetic standards, fan blade can also have multiple choices. First the angle of fan blade can be fixing can also be variable. Fixed angle blade advantage is in that cost is low, highly reliable. Variable angle vanes advantage is in that can tackle weather condition flexibly, and wind energy utilization is higher. Shape and the volume structure of next blade can also carry out free change as required.
The Main Function of driving device 3 is the stretching, extension and the contraction that drive the arm of force and blade, and wind-driven generator can adjust the operating mode of blade according to wind-force.
Blade 4 structure can be traditional wind blade construction, it is also possible to reference to ZL201510497988.1 intelligent blade structure for wind driven generator.
Supervising device 5 is Intellectualized controller, it is possible to monitoring blower fan and blower fan surrounding enviroment, controls blower fan according to ambient conditions and tackles various changes.Supervising device 5 is mainly made up of two parts, and a portion is monitoring device, obtains the various ambient parameter of periphery in real time by various monitoring devices. Another portion is for controlling device, and utilization records the surrounding enviroment each parts of state modulator blower fan and is operated.
