Abstract
The utility model relates to a wind generator comprising a generator, an input shaft, an output shaft and a fan blade, wherein, the input shaft is connected with the fan blade, and the output shaft is connected with the generator. The wind generator is characterized in that the fan blade is connected with the generator through a gearbox. Through the alteration of the transmission ratio between the fan blade and the generator, the utility model achieves the efficient conversion of wind power. By accelerating the rotation of the main shaft of the generator to such a great extent that the rotational speed of the main shaft of the generator is 70 times as high as that of the fan blade, the utility model improves the working efficiency of the generator.
Description
Technical field
The utility model relates to a kind of wind-driven generator, relates in particular to the improvement of the interconnection technique of wind-driven generator paddle and main frame.
Background technique
Present middle-size and small-size wind-driven generator adopts the directly driving type structure more, is characterized in that the fan blade flange plate directly is connected with engine shaft, and the rotating speed of fan blade is consistent with motor speed.This relatively simple for structure, although because big blade has than high pulling torque, and rotating speed is low, make that the input shaft rotating speed when fan blade drives generator by main shaft is lower, influenced the working efficiency of generator.And the volume of Low speed electric motor is too big, so be difficult to use on the high-power type.
The model utility content
The utility model is in order to provide a kind of wind-driven generator more than solving, it is by changing the velocity ratio between fan blade and the generator, to realize the efficient conversion to wind energy.
The technical solution of the utility model is: comprise generator, input shaft, output shaft, fan blade, input shaft is connected with fan blade, and output shaft is connected with generator, and described fan blade links to each other with generator by gearbox.
Parallel successively input shaft, jack shaft, the output shaft of being provided with is provided with input shaft gear in the described gearbox on described input shaft, but the gear I interlock on this gear and the jack shaft, and input shaft gear is greater than gear I; On described output shaft, be provided with output shaft gear, on jack shaft, also be provided with gear II, but described gear II and output shaft gear interlock, and gear II is greater than output shaft gear.
The utility model adopts gearbox to increase the rotating speed of generator shaft, the large scale fan blade has enough moments of torsion, but there is the low drawback of rotating speed, common Connecting format, be difficult to the wind energy that fan blade absorbs fully is converted into electric energy, after adopting speed-increasing transmission, utilize the enough moments of torsion of fan blade to drive generator and rotate.Structure for being arranged in parallel in the gearbox, saved a large amount of installing spaces, because input shaft gear is bigger than countershaft-gear I, so the rotating speed of jack shaft is than input shaft height, carried out speedup for the first time, countershaft-gear II specific output shaftgear is big simultaneously, so the rotating speed of output shaft is again than the rotating speed height of jack shaft, after twice speedup, the rotating speed of the rotating ratio fan blade of generator shaft has improved more than 70 times, significantly improve the rotating speed of generator shaft, improved the working efficiency of generator.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is input shaft among the figure, the 2nd, and fan blade, the 3rd, gearbox, the 4th, output shaft gear, the 5th, generator, the 6th, output shaft, the 7th, jack shaft, the 8th, gear I, the 9th, gear II, the 10th, input shaft gear.
Embodiment
Wind-driven generator, comprise generator 5, input shaft 1, output shaft 6, fan blade 2, input shaft 1 is connected with fan blade 2, output shaft 6 is connected with generator 5, described fan blade 2 links to each other with generator 5 by gearbox, the parallel successively input shaft 1 that is provided with in the described gearbox, jack shaft 7, output shaft 6, described output shaft 6 be arranged in parallel with input shaft 1, the parallel jack shaft 7 that is provided with between output shaft 6 and input shaft 1, on described input shaft 1, be provided with input shaft gear 10, gear I 8 interlock mutually on this gear and the jack shaft 7, input shaft gear 10 is greater than the gear I 8 on the jack shaft 7; On described output shaft 6, be provided with output shaft gear 4, on jack shaft 7, also be provided with gear II 9, gear II9 on the described jack shaft 7 and output shaft gear 4 interlock mutually, gear II9 on the jack shaft 7 is greater than output shaft gear 4, wind-drive fan blade 2 rotations during work, thereby driving input shaft 1 rotates, because input shaft gear 10 is bigger than the gear I 8 on the jack shaft 7, so the rotating ratio input shaft 1 of jack shaft 7 wants high, carried out speedup one time, gear II on the jack shaft 79 specific output shaftgears 4 want big simultaneously, so the rotating speed of output shaft 6 is again than jack shaft 7 height, after twice speedup, the rotating speed of the rotating ratio fan blade 2 of generator shaft has improved more than 70 times, significantly improve the rotating speed of generator shaft, improved the working efficiency of generator.
