First denoising device includes noise reducing plate, abatvoix 3 and the first sound insulation vibration damper plate 2, the noise reducing plate and sound-absorbing
Plate 3 is arranged at the upper end of the first sound insulation vibration damper plate 2, and the first sound insulation vibration damper plate 2 can break off noise reducing plate (or abatvoix 3) and ground
Acoustic between face, mainly isolation sound pass through the vibration transmitting between solid；The noise reducing plate is positioned close to substation 1
Side, noise reducing plate are used to completely cut off the noise that substation 1 generates or the noise that reduction substation 1 generates to 1 periphery transmitting of substation.
Preferably, noise reducing plate includes the first noise reducing plate 5 and the second noise reducing plate 4, and the first noise reducing plate 5 is positioned close to substation 1
Side, the first noise reducing plate 5 is equipped with rack gear 19 close to the side of the second noise reducing plate 4, and the upper end of the second noise reducing plate 4 is equipped with third electricity
Machine, the 5th gear 18 being arranged on third motor output end are engaged with rack gear 19, therefore can be dropped by third motor driven first
Plate 5 of making an uproar rises or falls.About 4 stack combinations of first noise reducing plate 5 and the second noise reducing plate, can increase noise reducing plate whole height,
Enhance noise reduction effect.
Second denoising device includes the second sound insulation vibration damper plate 6, soundproof plate 8, soundproof wall 7 and blower 10, the sound insulation
Plate 8 and soundproof wall 7 are arranged at the upper end of the second sound insulation vibration damper plate 6, the second sound insulation vibration damper plate 6 can break off soundproof wall 7(or every
Soundboard 8) and ground between acoustic；Mainly isolation sound passes through the vibration transmitting between solid.Soundproof plate 8 is positioned close to become
The side in power station 1 can be set sound insulation hole 17 on soundproof plate 8, can eliminate a part of noise by sound insulation hole 17, while can also
Acoustical cotton (marking not in the drawings) is arranged between soundproof wall 7 and soundproof plate 8, acoustical cotton can will be travelling through soundproof plate 8
Noise is absorbed again.For example, the gap width between soundproof wall 7 and soundproof plate 8 can be controlled in 10 ~ 20cm, also can
Acoustical cotton is set to fully absorb noise.Alternatively, soundproof wall 7 applies setting sound-deadening paint 21, and soundproof wall 7 close to the side of soundproof plate 8
Centre setting vacuum layer 20；Sound-deadening paint 21 and vacuum layer 20 can promote the soundproof effect of the second denoising device again, will make an uproar
Sound accumulates between soundproof wall 7 and soundproof plate 8, absorbs noise slowly by acoustical cotton.
