Description
Technical field:
The utility model relates to wind-driven generator, relates in particular to a kind of wind-driven generator that can make and normally start under the light air environmental conditions, and can move the light air actuating apparatus of generating.
Background technique:
The wind-driven generator that generally uses all comprises impeller at present, impeller shaft, gear, generator, the wind direction correcting device, storage battery etc., impeller is installed on the impeller shaft, impeller shaft drives the generator rotation by one group of gear, the wind direction correcting device is guaranteed impeller aligning wind direction, owing to all there is friction in the wind-driven generator between each movement parts, when wind-force during less than 3 grades (wind speed is less than 3.4m/s), wind-force to moment of torsion that impeller action produced less than static friction moment between each movement parts, thereby existing wind-driven generator can't start operation generating under the light air condition, and this is the major technique obstacle that the restriction wind-driven generator is applied.As everybody knows, wind energy is present in nature, and it is caused by solar radiant heat, and solar energy impinges is to earth surface, causes the earth surface inequality of being heated everywhere, produces the temperature difference, causes the convection current of atmosphere and forms wind.Wind is flow air, it has speed, and density is arranged, so contain energy, wind is inexhaustible clean energy resource, but the randomness that wind energy distributes is very strong, does not have specific rule, in different regions, Various Seasonal, the wind-force of different periods is all inequality, is not that the wind more than 3 grades is all arranged every day, and wind-force exists often less than 3 grades weather.At present, wind-driven generator can only for some power free fixed-site not timings electric energy is provided, or as the additional power supply of rural area, mountain area household electricity.How to make the wind-driven generator generating that can run well under the light air condition, this is the common technical barriers of paying close attention to and thirsting for solving of people.People have carried out a series of innovative design for this reason, the Fang Xianzhong professor of Jilin University discloses a kind of " vane type wind power generator " in patent 200720094027.7, it is to utilize two inverted each other suit awl tubes, blow generator impeller again after making the distinguished and admirable speedup that enters in the air conducting tube, thereby improve the speed and the density of the blade wind of flowing through, increase the volume flowrate of the blade wind of flowing through, forcing wind-driven generator to run well generates electricity, the purpose that realization utilizes light air just can generate electricity enlarges utilization ratio of wind energy.Its core technology is to improve the wind speed of the impeller of flowing through by a kind of wind-guiding device, reach the purpose of light air startup operation generating, this is a kind of theoretical techniques scheme of light air startup generating, also do not obtain practical proof, up to the present, the enforcement that is not applied as yet of this scheme is implemented and application difficult.
As everybody knows, for same kinematic pair, its dyanainic friction coefficient is less than the static friction coefficient, it is bigger than the impeller of the safeguarding rotary state energy needed that remains in operation promptly the impeller of wind-driven generator will to be entered the operating condition energy needed from state of rest, that is to say, under the prior art condition, though wind-force is less than light air deficiency generating so that wind-driven generator runs well of 3 grades, but if provide certain startup energy to wind-driven generator, make wind-driven generator enter operating condition from state of rest, the light air of wind-force below 3 grades just might be kept wind-driven generator normal operation generating so, based on this theoretical claimant after research and testing, found a kind of new departure that utilizes light air just can make wind-driven generator run well and generate electricity.
The model utility content:
The purpose of this utility model provides a kind of light air actuating apparatus of wind-driven generator, has been equipped with this device, and wind-driven generator just can move generating under the light air condition, improved the working time and the generating efficiency of wind-driven generator, has improved utilization ratio of wind energy.
The light air actuating apparatus of described wind-driven generator, it is characterized in that: it comprises impeller 1, impeller shaft 2, flying wheel 9, starting electrical machinery 80, worm-and-wheel gear 81, magnetic clutch 82, start axle 83, input gear 84, receive gear 85, impeller 1, flying wheel 9 and reception gear 85 are installed on the impeller shaft 2, input gear 84 is installed in and starts on the axle 83, starting electrical machinery 80 is by worm-and-wheel gear 81, magnetic clutch 82 and starter receiver group drives impeller axle 2 rotate, described starter receiver group is by input gear 84, receiving gear 85 forms, input gear 84 in the starter receiver group is controlled by magnetic clutch 82 with 85 engagements of reception gear or disengaging, described starting electrical machinery 80 is by storage battery 7 power supplies, and starting electrical machinery 80 and magnetic clutch 82 are by electric controller 11 controls.
Further, described flying wheel 9 is integrated with other rotating component that is installed on the impeller shaft 2;
