Description

A kind of H types vane of vertical shaft wind-driven generator constantly attack angle changing device
Technical field
The present invention relates to time-varying angle of attack during a kind of a kind of attack angle changing device, especially H types vane of vertical shaft wind-driven generator Device.
Background technology
The energy is the power of human social development.With the fast development of global economy, substantial amounts of coal, oil, natural gas Be consumed etc. fossil energy so that facing mankind unprecedented energy crisis and environmental threat, the energy and environmental protection into For significant problem urgently to be resolved hurrily at present.Wind generating technology is as in addition to nuclear power, and technology is most ripe, most exploit condition and hair The renewable energy power generation mode of exhibition prospect, is gradually paid much attention to by national governments.
Wind-driven generator is divided into rotary shaft pacifies perpendicular to the vertical axis windmill that wind direction is installed with rotary shaft parallel to wind direction The horizontal-shaft wind turbine of dress.Compared with horizontal-shaft wind turbine, vertical axis windmill can receive the wind that comes of any direction, therefore save The Yawing mechanism gone in horizontal-shaft wind turbine；Vertical axis windmill largely needs part (such as generator and gear safeguarded Case) it may be disposed on position near the ground or ground, it is very beneficial for the progress of maintenance work, and greatly reduce and safeguard into This；Blade profile is generally uiform section aerofoil profile, is easy to processing and manufacturing；Tip-speed ratio when vertical axis windmill is run is general left 2 The right side, will not substantially produce too big noise；What is be subject in vertical axis windmill running is permanent load, therefore blade Fatigue life is longer；Change of the vertical axis windmill to wind speed and direction is insensitive, in such a case, it is possible to more effectively use In complicated City Terrain, the ability of small-scale wind-power electricity generation is significantly improved.Because vertical axis windmill has above-described show Work advantage and increasingly paid much attention to by researchers.
The Wind Power Development of emerging market is rapid, is supported in national policy under the background nervous with energy supply, Chinese wind Power generation technology particularly wind power equipment manufacturing industry also emerges rapidly, has become global wind-power electricity generation the most active place. But from the point of view of world market, before foreign capitals wind-power electricity generation enterprise all occupies in occupation rate of market and technological precedence degree Row.The sound development of China's wind power generation industry is faced with some problems, in important core technology, further relies on foreign countries Chevron Research Company (CRC) is developed jointly, and to be caught up with and surpassed the relatively advanced country of other wind generating technologies in the world and be also needed to pay quite Many effort.At present, one of factor of restriction wind energy conversion system development is that wind energy utilization is relatively low, is primarily due to most of wind wheel Blade is all to be fixedly mounted, and setting angle does not change.When wind blows wind wheel rotation, the angle of attack of each blade also can be with It is azimuthal change and change, it is impossible to ensure the angle of attack of each blade in rational scope so that the blade having does positive work, Some blades do negative work, cannot also ensure the efficient utilization of wind energy.Therefore, if rationally setting each leaf of the wind wheel of rotation The angle of attack of piece so that the angle of attack of change at every moment in optimized scope, can thus greatly improve wind energy utilization.
The content of the invention
Present invention seek to address that above mentioned problem is filled there is provided time-varying angle of attack during a kind of H types vane of vertical shaft wind-driven generator Put, it is low and can not realize that blade constantly effectively becomes the angle of attack that it overcomes general H type vertical axis aerogenerator wind energy utilizations The drawbacks of, the technical scheme that it is used is as follows：
