The box inside of described end shield posts sound absorbing layer.Sound absorbing layer is posted in the casing outside of described end shield, and sound absorbing layer can absorb the generating set interior noise effectively.The long lumbar hole that described air-inlet grille is arranged horizontally.Described fixed head is a U type structure, and establish by long oval hole the centre, and center, fixed head long oval hole overlaps with end plate circular hole center.Lower end, described air inducing chamber lowest surfaces is equal with the lowest surfaces of air-inlet grille.
Compared with the prior art the present invention has the following advantages:
1. the present invention is provided with the bellows that surround air-inlet grille in the end shield inboard, and bellows play acoustic hood, and the noise in the generating set just spreads out of from air-inlet grille through after the sound insulation of bellows, can reduce the unit noise effectively to external radiation.
2. the position that is connected with air-inlet grille of bellows is a ramp structure, can prevent that rainwater from entering unit inside from air-inlet grille.
3. on the end shield inboard and the bellows outside, be equipped with sound absorbing layer, can absorb the generating set interior noise effectively.
4. the air inlet end shield is connected with generating set by fixed head, and the recessed end plate circular hole inboard that places of fixed head can make bolt not expose on the unit surface.
5. the outer setting at end body circular hole has rainproof plug, the complete shutoff of circular hole can be prevented that rainwater from entering generating set inside by circular hole.
