Abstract
The invention relates to a coaxial-direction wind-driven generator with double fan blades and is characterized in that two ends of a shaft of a wind driven generator are provided with two sets of fan blades with the same rotating direction, including a clockwise rotating fan blade A and a clockwise rotating fan blade B. When wind blows the clockwise rotating fan blade A or the clockwise rotating fan blade B, the clockwise rotating fan blade A or the clockwise rotating fan blade B is driven to rotate, and a rotational speed difference exists between the clockwise rotating fan blade A and the clockwise rotating fan blade B; when the clockwise rotating fan blade A rotates faster, a one-way bearing A arranged in a seat of the clockwise rotating fan blade A is stressed to drive the shaft of the generator to rotate to generate electricity; when the clockwise rotating fan blade rotates faster, a one-way bearing B arranged in a seat of the clockwise rotating fan blade B is stressed to drive the shaft of the generator to rotate to generate electricity. Thus, the clockwise rotating fan blade A and the clockwise rotating fan blade B work alternatively to drive the shaft of the generator to rotate to generate electricity, thereby enabling the generator to keep a stable power output at a low wind speed.
Description
Technical field
The present invention relates to a kind of wind energy power machine equipment, particularly relate to a kind of coaxial-direction wind-driven generator with double fan blade.
Background technique
Wind is a kind of nature green power source, utilize wind-power electricity generation to obtain very big environmental protection and economic benefits both at home and abroad, low wind speed starts and the power generating equipment that turns round exists a technical difficult problem but make full use of, and present known wind energy generating plant all is single group blade type structure, be difficult to starter generator or generator output power deficiency when hanging down wind speed, why present wind-driven generator can not get extensive use and popularization.
Summary of the invention
Technical problem to be solved by this invention is to overcome existing wind energy generating plant to have technological deficiency, provides a kind of simple in structure, and low wind speed can the quick starting running, and low wind speed output power is stable, the high wind speed coaxial-direction wind-driven generator with double fan blade stably that turns round.
The stable purpose of running during high wind speed can quick starting output power be increased in order to reach when hanging down wind speed.Coaxial-direction wind-driven generator with double fan blade of the present invention comprises generator, column, clockwise A fan blade, clockwise B fan blade, its feature also be same wind energy power the axle two ends two groups of fan blades are housed, clockwise A fan blade and clockwise B fan blade.A unilateral bearing and B unilateral bearing are equipped with in the inside of clockwise A fan blade and clockwise B fan blade, and A unilateral bearing and B unilateral bearing branch are installed in the generator shaft two ends in addition.Clockwise A fan blade and A fan blade seat interconnect, and the outer ring of A unilateral bearing is installed in A fan blade seat the inside by A bearing outer ring pin, and the inner ring of A unilateral bearing is installed in an end of generator shaft by pivot pin.
Same clockwise B fan blade and B fan blade seat interconnect, and the outer ring of B unilateral bearing is installed in B fan blade seat the inside by B bearing outer ring pin, and the inner ring of B unilateral bearing is installed in the other end of generator shaft by pivot pin.
Working principle of the present invention is such: the axle two ends of wind energy power are equipped with two groups with the fan blade, clockwise A fan blade and the clockwise B fan blade that turn to.When wind during to clockwise A fan blade or clockwise B fan blade, clockwise A fan blade of wind action band and suitable B fan blade rotate, at this moment there are speed discrepancy in clockwise A fan blade and clockwise B fan blade, when clockwise A fan blade rotating speed is fast, make to be installed in the stressed drive generator shaft rotation of A unilateral bearing generating in the clockwise A fan blade seat.When clockwise B fan blade rotating speed is fast, make to be installed in the stressed drive generator shaft rotation of B unilateral bearing generating in the clockwise B fan blade seat.Clockwise like this A fan blade and clockwise B fan blade alternation drive generator shaft and rotate generating, make generator keep stablizing power output at low wind speed.
As optimal design, this under wind action clockwise A fan blade and clockwise B fan blade rotate the wind energy power unit simultaneously, and clockwise A fan blade and clockwise B fan blade rotating speed are discontinuous mutually, always driving generator work, making wind-driven generator keep stablizing power output at low wind speed with the fast fan blade power of rotating speed.
