Abstract
A cross double-fan blade wind energy generator is characterized in that the power generation of the generator is realized through the alternate rotation of a clockwise positive fan blade and a vertical reverse fan blade; one end of a generator shaft is formed by connecting a first key pin with the inner side of the inner ring of a first one-way bearing; the outer ring of the first one-way bearing is integrally connected with a clockwise positive fan blade seat; the clockwise positive fan blade is connected outside of the clockwise positive fan blade seat; the other end of the generator shaft is formed by connecting a second key pin and the inner side of the inner ring of the second one-way bearing; a big bevel gear is mounted on the outer ring of a second one-way bearing; a small bevel gear is mounted on the upper surface of one end of a vertical shaft and is engaged with the big bevel gear in a rectangular way; the vertical shaft penetrates the bearing to be vertically mounted on the upper surface of an engine seat; the other end of the vertical shaft is formed by connecting a third key pin and a vertical fan blade seat; the vertical fan blade is connected outside the vertical fan blade seat; and a vertical column is mounted at the lower end of the engine seat.
Description
Technical field
The present invention relates to a kind of wind-driven generator, particularly a kind of quadrature wind-driven generator with double fan blade.
Background technique
Wind is the inexhaustible a kind of green power source of nature; Wind Power Utilization at present both at home and abroad is growing trend, but present wind energy power technology wind speed is when the 5 meter per second left and right sides, and the real output of wind-driven generator is 5.5% of a generator useful horsepower; This shows that present wind-driven generator wind speed must be greater than the useful horsepower that just can reach more than 7 meter per seconds about 50%; This major technique reason is that the used wind energy conversion system of these wind energy plants all is single group blade structure, and wind-engaging is bigger to the restraining factors of, wind speed, and wind energy utilization is low; Wind speed during less than 6 meter per seconds output power little; Running speed is stable inadequately, in wind speed fan blade starting difficulty during less than 5 meter per seconds, blower fan is rotated especially.
Summary of the invention
Technical problem to be solved by this invention is; Overcome at present existing wind energy power technology and have defective, provide a kind of simple in structure, can be when wind speed be lower than 5 meter per seconds can quick starting; Low wind speed output power is big, the high wind speed quadrature wind-driven generator with double fan blade stably that turns round.
In order to achieve the above object, the technological scheme that the present invention adopts is: a kind of novel quadrature wind-driven generator with double fan blade comprises support, generator, and the positive fan blade of pin vertically reverses fan blade, vertical shaft, first unilateral bearing, second unilateral bearing clockwise.Its invention structure characteristic also is; Generator for electricity generation is driven with two groups of fan blade alternate rotation of vertical reverse fan blade by clockwise positive fan blade, and an end of generator shaft is that first key pin is connected with the first unilateral bearing inner ring is inboard, and the outer ring of first unilateral bearing is connected with clockwise righteous style and practice trichidium consubstantiality; Clockwise positive fan blade is connected clockwise righteous style and practice trichidium outside; The other end of generator shaft is that second key pin is connected with the second unilateral bearing inner ring is inboard, and bevel gear wheel is equipped with in the outer ring of second unilateral bearing, and bevel pinion is installed in above vertical shaft one end and with auger tooth right angle and meshes; Vertical shaft is vertically mounted on above the support through bearing; The vertical shaft the other end is that the 3rd key pin is connected with the vertically-supplying air trichidium, vertically reverses fan blade and is connected vertical backing wind trichidium outside, and column is installed in the lower end of support.
Working principle of the present invention is such: when when natural wind speed is lower than 5 meter per seconds, blowing to clockwise positive fan blade or vertically reversing fan blade; Because of clockwise positive fan blade is that direct reaction force through unilateral bearing drives the generator shaft rotation; Because the load of generator exists wind speed too low, the very difficult starting of effect that at this moment clockwise positive fan blade does not have extraneous power is rotated, but the present invention has installed unilateral bearing and appearance bevel gear not of uniform size at the generator shaft the other end; Vertical shaft and vertical reverse fan blade are installed above the bevel pinion; Alleviate vertical reverse fan blade moment of rotation through little bevel gear wheel speed ratio, make vertical reverse fan blade can be when wind speed be lower than 5 meter per seconds under the effect of wind-force quick starting rotate, and make in the auger tooth unilateral bearing reaction drive generator shaft through little bevel gear wheel engagement to rotate; Generator shaft one rotates the clockwise positive fan blade of the other end is also rotated thereupon; Make generator acting generating, take away energy, make vertical reverse fan blade slack-off with one group of fan blade rotating speed wherein of clockwise positive fan blade because of the generator acting; Because unilateral bearing has been installed at these bright two ends at generator shaft; Make two groups of fan blades independent rotation that is independent of each other, again can the reaction of unilateral bearing under drive generator shaft and rotate, make two groups of fan blades always big one group of moment drive generator work; The vertical simultaneously installation advantage that reverses fan blade and clockwise positive fan blade out of phase makes wind energy reach big utilization again.
As optimal design; This under the effect of wind-force clockwise positive fan blade rotate the work of drive generator simultaneously with vertical reverse fan blade; But clockwise positive fan blade is discontinuous mutually with vertical reverse fan blade rotating speed; Can there be one group of fan blade to be in effective working state again and drives generator work, make the wind energy power function that electric rate output arranged when wind speed is lower than 5 meter per seconds.
