Section is parallel with front apron 713, rear baffle 714 and bottom baffle 715 respectively, and second chamber 752 thus is separated into two second and is total to
Shake chamber 762, i.e., second resonant cavity between the second chamber partition plate 74, top baffle 716, intermediate bulkhead 72, right shell body 712
762, remainder then forms another the second resonant cavity 762.Can also set in another resonant cavity 762 another the
Two compartment spacers 74, in tabular, extend between intermediate bulkhead 72 and right shell body 712, thus by another second resonance
Chamber 762 is divided into two.
At least two first sound-absorbing hole 771 and at least two second sound-absorbing hole 772 are offered on top baffle 716, first inhales
771 and second sound-absorbing hole 772 of acoustic aperture is distributed in the top of first chamber 751 and second chamber 752, it is preferred that the first sound absorption
Hole 771 can be in array-like, be covered with the surface of top baffle 716, and 772 surface straggly for being arranged in top baffle 716 of the second sound-absorbing hole.
First sound-absorbing hole 771 can be round hole, square hole, hex hole etc., its a diameter of 1mm~5mm, this is because noise reduction module
7 is close or be close to have certain spacing between cover board 64, with ternary wind turbine 4, and noise frequency range is wider, only by the first sound-absorbing hole
771 diameter reduces within the above range, and noise reduction module 7 could be caused to reach band limit.The diameter of second sound-absorbing hole 772 is big
In the first sound-absorbing hole 771.
Top baffle 716 has attached the first acoustical cotton 781 above, is offered on the first acoustical cotton 781 and the second sound-absorbing hole 772
Matched 3rd sound-absorbing hole 773, so as to increase the acoustic absorptivity of low-frequency noise.Top baffle 716, the first acoustical cotton 781 and cover board
64 can be close to mutually.The outside (arranged on left and right sides of wind deflector 6) of the side wind deflector 62 of wind deflector 6, the main body 61 of wind deflector 6
The position that the rear side of bending part 612 is located at the lower section of ternary wind turbine 4 can attach the second acoustical cotton 782, further in ternary wind turbine 4
Noise transmission path on reduce noise.
Due on 4 lower section noise transmission path of ternary wind turbine, leftward position is mainly high-frequency noise, therefore above-mentioned first
The cavity volume of resonant cavity 761 is less than the second resonant cavity 762, i.e. the first resonant cavity 761 can increase the sound absorption system to high-frequency noise
Number, the second resonant cavity 762 is then semi-open space, increases the acoustic absorptivity to mid-frequency noise.This mazy resonant cavity
Add the wide band sound absorption of the first acoustical cotton 781.
Alternatively, first chamber partition plate 73 and second chamber partition plate 74 can also be other shapes, as long as can separate
Space in one chamber 751 and second chamber 752, each resonant cavity after segmentation can be cuboid, cylinder, cone,
Irregular body etc..In addition, sound absorption back of the body intracavitary, the surface of each resonant cavity can also attach acoustical cotton.
In order to reduce absorbed noise frequency, micro-pore diameter is reduced, increases the spacing between adjacent cells, increase resonance
The height of chamber, the largest interval between each sound-absorbing hole preferably should be 1/5th of corresponding wave length of sound, preferably 8~
50mm, largest interval 70mm, the highly preferred of each resonant cavity should be 1/3rd of corresponding wave length of sound.
By above-mentioned arrangement, ternary wind turbine 4 has very well close to noise reduction module 7 for 4 radiated noise of ternary wind turbine
Inhibitory action, it is and compact-sized.And the structure of noise reduction module 7, sound absorption frequency range greatly improved, can effectively absorb each frequency range
Noise.
At least one first oil dripping hole 7151 is offered on bottom baffle 715, the second oil dripping is offered on the bottom plate 17 of housing 1
Hole 171 (can be corresponding with the first oil dripping hole 7151, can not also correspond to), and the position of above-mentioned oil dripping hole and the position of lubricating cup 3
Put correspondence.Even if thus there is the grease after separation to enter noise reduction module 7, it can also pass through the first oil dripping hole 7151 and the second oil dripping hole
171 are discharged to lubricating cup 3, in order to avoid influence the noise reduction of noise reduction module 7.
