Abstract
The utility model relates to an engine noise reduction cover for sound insulation and noise reduction. The noise reduction cover comprises a cover body and a pedestal. The cover body is a hollow rectangular structure prepared from a thin metal steel plate. An intermediate bulkhead is horizontally arranged close to one end inside the cover body. A square opening is arranged on the intermediate bulkhead. A through hole is arranged on a cover wall at the other end of the cover body. The inner wall of the cover body and the board of the intermediate bulkhead are equipped with a damping material layer. Two laterally-overturn side opening doors are alternately arranged along the longitudinal direction of the cover body between the intermediate bulkhead and the other end of the cover body on a cover wall at one side of the cover body. Two vertically-overturn up-sliding doors are alternately arranged along the longitudinal direction of the cover body between the intermediate bulkhead and the other end of the cover body on a cover wall at the other side of the cover body. With the noise reduction cover installed on a generation welding all-in-one machine of a mobile welding workshop, noise of an engine and a generator and noise generated during the welding operation can be effectively reduced. It is proved through a field test that noise is reduced from 86dB to 70dB below and work environment of constructors is improved.
