Abstract

A vertical wind-driven generator with double fan blades has the following advantages: two groups of fan blades are vertically installed on the same generator shaft and are independent of each other but can rotate by being matched with each other at speed to drive the generator to generate power. The working principle of the generator is as follows: breeze-started fan blades, an outer shaft sleeve and a main transmission gear are connected as a whole; the outer shaft sleeve is installed outside the generator shaft by bearings; the diameter of a big transmission gear is larger than that of the main transmission gear, so the meshing transmission torque of the main transmission gear and the big transmission gear is reduced; the big transmission gear is connected with a small transmission gear up and down by a transmission shaft and the diameter of the small transmission gear is smaller than that of a torque gear; the transmission torque is further reduced to reduce the starting force of the breeze-started fan blades; when the breeze blows the breeze-started fan blades, the breeze-started fan blades can rotate quickly; the rotating force passing through the main transmission gear, the big transmission gear, the small transmission gear and the torque gear and the reacting force of a one-way bearing connected with the inner hole of the torque gear ensure the generator shaft to rotate; and as main fan blades are connected with the generator shaft as a whole, the main fan blades simultaneously rotate, thus achieving the aim of starting the main fan blades by the breeze to operate to generate power.

Description

Rectilinear wind-driven generator with double fan blade
Technical field
The present invention 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, and the generating wind speed must reach 4.2m/s, sets 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, exists because of generator has certain load, and therefore present vertical fan blade wind energy power technology has retrained applying of wind-power electricity generation.
Summary of the invention
The technical problem that the present invention will solve 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 ability 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 present invention adopts is: a kind of rectilinear wind-driven generator with double fan blade comprises 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 through the main blade connecting rod, and the endoporus of outer sleeve is vertically mounted on the outside of generator shaft through the clutch shaft bearing and second bearing; Gentle breeze starting fan blade is connected with the external axle sleeve outside through gentle breeze starting fan blade connecting rod; Main drive gear is installed in the external axle sleeve lower outside and rotates with big driving gear engagement, and big driving gear, small transmission gear are installed in above the transmission shaft through second pivot pin and the 3rd pivot pin, and 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 through key pin, and the inner ring of unilateral bearing is installed in above the generator shaft lower end through first pivot pin, and torque gear and small transmission gear engagement are rotated.
Working principle of the present invention is such; When gentle breeze blowed to main blade, because of main blade is directly to drive generator to rotate, this moment was 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, but the present invention has installed gentle breeze starting fan blade, and gentle breeze starting fan blade, external axle sleeve, main drive gear consubstantiality connect; Outer sleeve passes through Bearing Installation in the generator shaft outside; And the diameter of big driving gear is greater than main drive gear, so the main transmission tooth reduces with big driving gear engagement driving moment, and big driving gear is connected up and down through 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, when gentle breeze blows to gentle breeze starting fan blade, can rotate very soon; Rotatory force is from main drive gear, big driving gear, small transmission gear, torque gear, rotate generator shaft through the reaction force that is contained in torque gear endoporus unilateral bearing again; Because of main blade is connected with the generator shaft consubstantiality, so also rotation simultaneously of main blade, reached gentle breeze starting main blade running generating purpose.
Invent design as optimizing, 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, make rectilinear wind-driven generator with double fan blade at the weather of gentle breeze certain electric power output can be arranged.
