Description

A kind of multilayer wind-power electricity generation sail

Technical field

The present invention relates to a kind of used for wind power generation sail of wind generating unit, particularly a kind of vertical multilayer wind-power electricity generation sail that is used for vertical wind power generation.

Background technique

Wind energy is a kind of energy of cleaning, and in the today of being becoming tight world energy sources day, wind energy receives the many concerns of People more and more.Wind wheel is the vitals of wind-driven generator, and whether the structure of wind wheel rationally is directly connected to the operational efficiency of wind-driven generator.At present; The wind wheel of the propeller type that common wind turbines rotor is made up of three or more blade; Wind wheel and generator main body constitute the generator head; It is installed on the blower fan king-post to be approximately perpendicular mode, because the wind wheel blowing area of this structure is little, the generated energy of generator receives certain restriction.Be to increase blowing area, or make the wind wheel swept surface, or improve generator performance and from the purpose of Security aspect etc. always perpendicular to prevailing wind direction; Usually through adding linear leaf; The modes such as yaw system, hydraulic system, booster engine, fin, pitch regulating mechanism, cowling that are provided with realize that these devices that mainly are positioned at the head section of generator rotation directly cause the generator head heavy, for the MW class generator; Its weight reaches thousands of tons of, and the fan blade radius reaches 70～80m.All very high to the precision and the material requirements of fan blade processing like this; Cause its cost high; Thereby directly cause the high deficiency of wind-power electricity generation valency, simultaneously, because the blade turning radius will cause wing tip speed supersonic speed to produce shock wave and vibration greatly; Not only reduced efficient, also sent very big noise and cause noise pollution; In addition, because blade is long, body of the tower is high, occurs the fault of blade broken easily, the potential safety hazard that exists blade to fly out to ruin thing, hurt sb.'s feelings.For this reason, those skilled in the art also carried out corresponding improvement, and had obtained certain effect.Chinese patent notification number: CN201443470U; Date of declaration on April 28th, 2010, invention and created name " big sail vertical rotating wind turbines rotor " discloses a kind of wind wheel of vertical rotating wind-driven generator; It is made up of a vertically disposed vertical shaft and several vertically disposed sail blades; The sail blade is distributed on the vertical shaft, and a retaining control wind shell is arranged in the outside of impeller, forms airflow channel by retaining control wind shell; Wind-force promotes blade and drives the column rotation continuously, thereby realizes the purpose of wind-power electricity generation.Though this technological scheme has solved existing wing formula wind-driven generator and has made the problem that difficulty is high, maximum generating watt is difficult to further raising; But itself is owing to be provided with retaining control wind shell, not only has complex structure, deficiency that manufacture cost is high, simultaneously; Because blade is fixedly connected with column; In the sail wind-engaging force urges in airflow channel, its sail of tossing about also can receive the part wind and column produces rightabout thrust, causes the deficiency of wind-force waste; In addition, because sail only is provided with one group at vertical direction, limited by current material and manufacture level, sail size and generated energy receive certain restriction, also can cause wind-force to be not fully utilized.For this reason, need further to improve.
