Abstract

A vertical dual-blade wind power generator has the advantage that two blades vertically mounted on the same power generator shaft are independent from one another but capable of rotating in a coordinated manner to drive the wind power generator to generate power, a breeze starting blade, an outer shaft sleeve and a main transmission gear are connected consubstantially, an outer sleeve shaft is mounted outside the power generator shaft through a bearing, the diameter of a large transmission gear is larger than that of the main transmission gear so that the transmission moment for meshing a main transmission tooth with the large transmission gear is reduced, the large transmission gear and a small transmission gear are vertically connected through a transmission shaft, and the diameter of the small transmission gear is smaller than that of a moment gear so that the transmission moment is further reduced and the starting power of the breeze starting blade is reduced. When exposed to breeze, the breeze starting blade can rotate quickly, and the rotating force drives the main shaft of the power generator to rotate through the main transmission gear, the large transmission gear, the small transmission gear, the moment gear and the reacting force of a one-way bearing installed in the inner hole of the moment gear. Because a main blade and the power generator shaft are connected consubstantially, the main blade rotates at the same time, which ensures that the purpose of utilizing breeze to start the main blade for power generation is achieved.

Description

Rectilinear wind-driven generator with double fan blade

Technical field

The utility model relates to a kind of wind-driven generator, particularly a kind of rectilinear wind-driven generator.

Background technique

Present known vertical wind-driven generator, all be to adopt vertical single-group type blade structure to drive generator for electricity generation, starting the wind speed requirement according to this rectilinear single fan-blade wind energy generator of data is 3.5m/s, the generating wind speed must reach 4.2m/s, set up the annual mean wind speed that wind power station need be not less than 5m/s by existing vertical wind power generation technology, understand according at present vertical fan blade wind energy power technology according to me, wind speed starts the wind-driven generator generating when 3.5m/s also be very difficult, exist because of generator has certain load, therefore present vertical fan blade wind energy power technology has retrained applying of wind-power electricity generation.

Summary of the invention

The technical problems to be solved in the utility model is; Overcome the technological deficiency of the low wind speed fail to start of at present vertical fan blade wind-driven generator existence, provide a kind of simple in structure, low wind speed energy quick starting, and low wind speed has electric energy output, the rectilinear stably wind-driven generator with double fan blade of high wind speed running.

Can be in order to reach in low wind speed quick starting purpose, the optimisation technique design proposal that the utility model adopts is: a kind of rectilinear wind-driven generator with double fan blade, comprise generator, unilateral bearing, gentle breeze starting fan blade, outer sleeve, main blade, casing, its inventive features and advantage are that main blade is installed in above the generator shaft by the main blade connecting rod, the endoporus of outer sleeve is vertically mounted on the outside of generator shaft by the clutch shaft bearing and second bearing, gentle breeze starting fan blade is connected with the external axle sleeve outside by gentle breeze starting fan blade connecting rod, main drive gear is installed in the outside, external axle sleeve lower end and rotates with big driving gear engagement, big driving gear, small transmission gear is installed in above the transmission shaft by second pivot pin and the 3rd pivot pin, the two ends of transmission shaft are connected with the 4th brearing bore with the 3rd bearing, the outer ring of the 3rd bearing and the 4th bearing is installed in above the housing, the endoporus of torque gear is connected with the unilateral bearing outer ring by key pin, the inner ring of unilateral bearing is installed in above the generator shaft lower end by first pivot pin, and torque gear and small transmission gear engagement are rotated.

Working principle of the present utility model is such; When gentle breeze blows to main blade, because of main blade is directly to drive generator to rotate, this moment is because the energy shortage of wind and generator load existence, therefore gentle breeze can not make the main blade across-the-line starting drive the generator operation generating, the utility model has been installed gentle breeze starting fan blade, and gentle breeze starting fan blade, external axle sleeve, the main drive gear consubstantiality connects, outer sleeve by Bearing Installation in generator shaft outside, and the diameter of big driving gear is greater than main drive gear, therefore the main transmission tooth reduces with big driving gear engagement driving moment, big driving gear is connected up and down by transmission shaft with small transmission gear, the diameter torque gradient gear of same small transmission gear is little, further reduce driving torque, gentle breeze starting fan blade starting force is reduced, can very fast rotation when gentle breeze blows to gentle breeze starting fan blade, rotatory force is from main drive gear, big driving gear, small transmission gear, torque gear, by the reaction force that is contained in torque gear endoporus unilateral bearing generator shaft is rotated again, because of main blade is connected with the generator shaft consubstantiality, therefore main blade also rotates simultaneously, has reached gentle breeze starting main blade running generating purpose.

As optimizing the invention design, this two groups of fan blades are vertically mounted on the same generator shaft and do not involve mutually, but speed cooperates rotation to drive generator for electricity generation mutually, makes rectilinear wind-driven generator with double fan blade at the weather of gentle breeze certain electric power output can be arranged.
