Embodiment Construction

[0010] Referring to Figures 1 and 2, the one-shaft multi-machine speed-up wind power generator set includes a rotating shaft 2 with wind-powered rotating blades 1, and the rotating shaft 2 is supported by a bearing frame 3. A large internal gear 4 and four small external gears 5 meshed with the large internal gear 4 are installed on the rotating shaft 2 , and each small external gear 5 is correspondingly connected with an input shaft of a permanent magnet multistage generator 6 . The wind blows the blade 1 to rotate, drives the rotating shaft 2 to rotate, then drives the large internal gear 4 to rotate, drives the four small external gears 5 in the large internal gear 4 to rotate, realizes the speed increase, and drives the four permanent magnet multi-stage generators 6 to rotate generate electricity. The power of each permanent magnet multistage generator is about 300kw, but not limited thereto. (the big gear is omitted in the structural diagram of the external gear).

Abstract

The invention relates to a wind power generating set, namely a speed-increasing wind power generating set with one shaft and multiple machines; the invention comprises a rotating shaft with rotating blades and a permanent-magnet multistage generator; the rotating shaft is provided with a large inner gear and at least two or more than two small outer gears which are meshed with the large inner gear, and each small outer gear is connected with an input shaft of the permanent-magnet multistage generator correspondingly; a plurality of generators with permanent magnet, multiple stage, low speed and low power are combined to be used, and realize synchronous speed-increasing with the same speed; the invention is characterized by simple and compact structure, low cost, reliable technology, convenient maintenance and long operation life.

Description

technical field [0001] The invention relates to a wind power generating set, that is, a one-shaft multi-machine speed-up wind power generating set. Background technique [0002] In the prior art, wind power generators require relatively large power, and usually there is one generator corresponding to one rotating blade. The technical requirements for manufacturing high-power generators are difficult, and the quality is difficult to meet the design requirements. Contents of the invention [0003] The object of the present invention is to provide a one-shaft multi-machine speed-up wind power generating set that satisfies the simultaneous speed-up use of multiple generators in order to solve the above-mentioned shortcomings. [0004] The technical solution of the present invention is: a one-shaft multi-machine speed-up wind power generator set, including a rotating shaft (one shaft) with wind-driven rotating blades, and a permanent magnet multi-stage generator. One or more ...
