Wind power generating set

Technical field

The present invention relates to a kind of generator, especially a kind of wind power generating set.

Background technique

Along with development of science and technology, the energy seems more and more important to a national economy and development of science and technology, owing to the tradition generating is to rely on the coal resource burning to produce electric energy, have seriously pollutedly, and coal resource is also non-renewable, therefore, the development novel energy has become the inexorable trend of energy development, and wind-power electricity generation has little investment, environmental protection and generating efficiency height because of it, in the novel energy evolution, has remarkable advantages.

In the general wind-power electricity generation process, the wind-driven generator that is adopted includes fan blade and single generator body, and fan blade is connected with the central rotating shaft of this single generator body usually; When generating, the wind blows fan blade rotates, and then the central rotating shaft that drives generator rotates and generates electricity, though this wind-driven generator is simple in structure, because it is to rely on single fan blade to drive single generator set to generate electricity, the electric energy that each generator produced has certain restriction, its generating efficiency is very low, in order to improve generating efficiency, often needs to adopt relatively large number generator, but generator mark is big more, can cause whole generating device structure weight to increase; And owing to the wind impeller structure reason, it is in the face of more weak distinguished and admirable of intensity the time, and rotating speed is generally very low, has further limited the generating efficiency of wind-driven generator, therefore, from above structural analysis as can be known, is necessary the wind-driven generator of this kind structure is improved.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of wind power generating set, and this wind power generating set generating efficiency is not subjected to the restriction of the generating efficiency of single generator body, the generating efficiency height.

For solving the problems of the technologies described above, wind power generating set of the present invention adopts following technical proposals: this wind power generating set, comprise fan blade and the generator that is in transmission connection with fan blade, the cylindrical shape of described fan blade, described fan blade offers a plurality of air intake through holes at interval uniformly along its circumferencial direction, be provided with central rotating shaft in the fan blade central position, the rotor that described generator has a plurality of and each generator is in transmission connection with an end of this central rotating shaft respectively.

Design concept according to invention, also be arranged with rectifying device in described fan blade outside, described rectifying device is also cylindrical, this rectifying device center is provided with mounting hole, described mounting hole and described fan blade external shape are suitable, described fan blade is positioned at this mounting hole and can rotates along this mounting hole, be provided with a plurality of rectification grooves uniformly at the circumferential interval of rectifying device, the corresponding to side of extension of central axis direction of this each rectification groove and rectifying device is a curved surface, it is evenly distributed that the cross section of described each rectification groove is clockwise direction along the center of rectifying device, and described rectification groove reduces from being positioned at the rectifying device outside to rectifying device side opening gradually along the side of this rectification groove.

Design concept according to invention, described generator is four, around the central rotating shaft that is distributed in described fan blade that these four generators walk abreast respectively, be provided with drive wheel at described central rotating shaft and the corresponding position of generator, the rotor of each generator is in transmission connection by the drive wheel of drivign belt and central rotating shaft.

Compared with prior art, the present invention has following beneficial effect: (1) is because wind power generating set of the present invention has a plurality of generators, when generating, these a plurality of generators are worked simultaneously, exportable more electric energy, improve the efficient of generating, traditional relatively wind power generating set has advantages such as generating efficiency height, structure are light and handy; (2) because the present invention also is arranged with rectifying device in the fan blade outside, under the effect of this rectifying device, more weak wind can be converted into stronger air-flow relatively relatively, and the fan blade rotating speed is increased, and then makes the rotating speed of fan blade increase, and improves the efficient of generating; (3) because the present invention is provided with four generators, and these four generators are in transmission connection by the drive wheel of drivign belt and generator central rotating shaft, and it is simple in structure, cost is lower.

Embodiment

Referring to Fig. 1, wind power generating set of the present invention comprises fan blade 1 and generator 2, and wherein, generator 2 is in transmission connection with fan blade 1, under the effect of described fan blade 1, and the generating of the rotor rotation of generator 2.

Referring to Fig. 2, described fan blade 1 cylindrical shape of the present invention, on this fan blade 1, offer a plurality of air intake through holes 11, described each air intake through hole 11 evenly is provided with at interval along this fan blade 1 circumferencial direction, be provided with central rotating shaft 12 in described fan blade 1 central position, when fan blade 1 rotatablely moved under the wind-force effect, described central rotating shaft 12 also rotated thereupon.

Described generator 2 has a plurality of, it is positioned at an end position of central rotating shaft 12, and each generator 2 is in transmission connection with this central rotating shaft 12, generator 2 of the present invention is preferably four, around the central rotating shaft that is distributed in described fan blade 1 12 that these four generators are parallel respectively, at described central rotating shaft 12 and generator 2 end that is in transmission connection drive wheel 21 is set preferably, the rotor of described each generator 2 is in transmission connection by drivign belt and this central rotating shaft 12, and this each generator 2 is sealed by lid 4; When fan blade 1 rotatablely moved under the wind-force effect, described central rotating shaft 12 rotated thereupon, by drive wheel 21 and the drivign belt that is positioned at its end, drive the rotor rotary electrification of each generator 2, these a plurality of generators 2 are worked simultaneously, exportable more electric energy, and then improved the efficient of generating.
