Specific implementation mode
It please refers to Fig.1 to Fig. 4, noise reduction integrated transformer wind turbine, including an air duct 1, motor 2, a Duo Ge electricity
3, wheel hubs 4 of machine support, multiple blades 5, first mute structures, 6, second mute structures 7.
Motor 2 is fixed on by electric machine support 3 inside air duct 1；Blade 5 is connect by wheel hub 4 with motor 2.For safety,
On air duct 1 plus there are one outer covers 8.First mute structure 6 includes the first silencing cotton 61, the first silencing cotton frame 62, first
Frame 63；First silencing cotton 61 is in the first silencing cotton frame 62, which is that Openworks shape facilitates inside
Silencing cotton absorbs noise, and the first silencing cotton frame 62 is fixed on 2 front of motor by first support 63, which is general
Logical supporting structure is preferably selected cylinder or Elliptic Cylinder, reduces windage in this way.62 front of above-mentioned first silencing cotton frame
For conical structure, the effect of diffusion and even wind is played in this way.First support 63 and the first silencing cotton frame 62 are pressed from both sides at 45-60 degree
Angle is arranged, and is conducive to air circulation in this way.
Second mute structure 7 is in 2 rear of motor, which includes the second silencing cotton 71, the second silencing cotton
Frame 72, the second frame rack 73；Second silencing cotton frame 72 includes mute cylinder 722 in outer 721, one, a mute cylinder, on
Outer 721 forefront of mute cylinder tool is stated there are one encapsulated conical silica gel 9, is achieved the transition of wind, i.e., wind first with it is soft
Silica gel 9 contacts, and is then the second frame rack 73 contact of hard；Interior mute cylinder 722 and outer mute cylinder 721 be Openworks shape simultaneously
Filled with above-mentioned silencing cotton；Interior mute cylinder 722 is fixed on outer 721 center of mute cylinder by the second frame rack 72；It is outer quiet
Sound cylinder 722 is fixed on by the second frame rack 72 inside air duct 1, and 722 outside of the interior mute cylinder is conical structure, in this way
Convenient for supercharging.Second frame rack 72 is Z-shaped, is convenient for so fixed and saves material.
