Description
Technical field
A kind of technical field of wind power generator is the utility model is related to, one kind is provided in particular in and is used for vertical axis wind power generation
The overall generator of machine.
Background technology
Vertical axis aerogenerator of the prior art, in order that wind energy is converted into the process of electric energy and preferably carried out,
Two generators up and down are typically used, two generators form the generator of monoblock type by a sleeve connection.Existing
In integrated wind power generator, generator external rotating part is held by the dish axle of upper, middle and lower three to be coupled with integral central axle, blade
By support bar support, the rotating part rotation of driving generator external is generated electricity, so as to realize that the wind energy for absorbing blade turns
Turn to electric energy.For the vertical axis aerogenerator of low power wind-driven generator, such as 20KW, two generatings are not often needed
Machine, and if set two generators not only increase the complexity of system, but also can influence complete machine operational effect and can
By property.
In addition, the vertical axis aerogenerator of low power monomotor of the prior art, its structure is generally such as Fig. 6 institutes
Show, including upper, middle and lower three parts, bottom is divided into generator, and generator is outer rotor generator 04, the hair of outer rotor generator 04
Motor center axle 041 is arranged in tower 05, and the outer rotor in outer rotor generator 04 passes through upper and lower two dish axle with central shaft 041
Hold connection.Middle part is divided into middle king-post 03, the generator central shaft 041 of the bottom connection engine 04 of middle king-post 03.Top
It is divided into rotary part 01, including wheel hub 011 and hub central axle 012, wherein wheel hub 011 and hub central axle 012 is by upper
Lower two dish axles hold connection, and generator central shaft 012 is connected with the upper end of middle king-post.The blade of generator is arranged on upper and lower two
On strut, upper support bar is fixed on wheel hub 011, and lower support bar is fixed on outer rotor.By synchronous sleeve 2 by outer rotor and
Wheel hub 011 is linked together, and synchronous cylinder 2 is formed by connecting by upper bush 021 and lower sleeve 022, and the upper end of upper bush 021 connects
It is connected on wheel hub 011, the lower end of lower sleeve 022 is connected on outer rotor.
In the installation process of above-mentioned generator, first, outer rotor generator 04 is arranged in tower 05, then by
Between king-post 03 be arranged on generator central shaft 04, lower sleeve is arranged on outer rotor, hub central axle 012 and middle king-post
03 connection, upper bush, the bottom connection lower sleeve of upper bush, top connection wheel hub are finally installed.Supported on wheel hub in connection
Bar support, connects lower support bar support on outer rotor, and the upper and lower side of each blade is separately fixed at located at upper lower support bar branch
On upper lower support bar on frame.
