Abstract
The invention relates to a parallel type direct-driven wind power generator with a hub and a power generator outer rotor combined. A hub and power generator rotor combination assembly is mounted on a cabin assembly. A parallel type direct-driven power generator assembly is arranged in a mounting chamber. Each power generator assembly is provided with a power generator permanent magnet mounted on the hub type outer rotor and a power generator rotor iron core. Stator windings and stator iron cores are arranged at the positions, in one-to-one-correspondence with the power generator permanent magnets, in the mounting chamber. The stator wining and the stator iron core in each power generator assembly are both mounted on a separate stator support. The power generator assemblies are arranged to be in parallel connection with one another. By means of the parallel type direct-driven wind power generator, the size of the whole assembly is remarkably reduced; cantilever force of a cabin and a tower barrel is reduced; and meanwhile, in order to further cooperate with reduction of the structural size, the parallel type direct-driven power generator assembly of the special structure is adopted, and on the basis that overall power is not influenced, manufacturing cost and mounting cost can be remarkably lowered.

In known technical field, wind power generating set is divided into internal rotor and the structure of two kinds of forms of outer rotor, whether
Internal rotor or outer rotor, are all the kinetic energy being captured wind by Wind wheel paddle, input turning effort, i.e. wind wheel by generator one end
Couple between wheel hub one end and the input of generator.
This kind of direct wind-driven generator generally existing power that design produces both at home and abroad at present is bigger, and the diameter of wind wheel is got over
Greatly, rotating speed is slower, and torque is bigger, leads to the structure entirely directly driving generating set too fat to move, brings not to manufacturing, transporting, install
The difficulty that can go beyond.The wind power generating set of the such as diameter 6m that external Siemens Company produces at present, generator amature straight
Footpath is in 7m, and domestic corporation then needs to reach more than 7.5m, and generator diameter is excessive, only the development of a restriction wind power generating set
Bottleneck.
Known direct-driving type wind power generation unit is all made up of the big assembly structure of wind wheel, generator, cabin, tower etc. four
's.Four big assemblies generally described above are in the distribution of side-by-side, because wind wheel assembly is single integral structure, are simultaneously located at and send out
The input of motor, i.e. front end, so the distance between the focus point of the focus point of wind wheel to tower can be with generator power
Increase and increase.Because wind wheel weight more than megawatt rank is typically in tens tons to up to a hundred tons weights, therefore the wind of traditional structure
If power generator increases power, the focus point of its wind wheel arrives the distance between focus point of tower can increasing in geometry multiple
Plus, so indirectly increased the cantilever force of cabin and tower.Thus leading to tower structure to increase to thicken, the base of Wind turbines is installed
Plinth assembly is also required to accordingly increase the cost of construction.Show, direct-drive aerogenerator group is integrally tied from above-mentioned can summary
Structure is too fat to move to hardly result in solution mainly due to two problems, and one is the distance between the focus point of the focus point of wind wheel to tower
Longer, power is bigger, and its distance is longer, thus need to re-start on integral layout consider it is clear that, another one
Problem is that the version of the most crucial generator of generating set needs to make a change, the structure of general wind-driven generator be as
Patent name is：Wind power generating set (Publication No.：CN105673327A disclosed in), " wheel hub, described wheel hub is provided with connection
