Embodiment 1

[0038] A soundproof outer cover for a silent generator set 2, comprising a soundproof outer cover body 1 disposed outside the generator set 2;

[0039] The soundproof outer cover body 1 includes an inner layer plate 11 and an outer layer plate 12, an airtight cavity 13 is formed between the inner layer plate 11 and the outer layer plate 12, and an air suction port 14 is provided on the outer layer plate 12;

[0040] A sound-absorbing material layer 15 is provided on the side of the inner plate 11 facing the generator set 2 .

[0041] The soundproof enclosure body 1 is a rectangular enclosure surrounded by four side panels 16 and a top panel 17 . The top plate 17 is provided with a through hole 171 for exhaust. The sound-absorbing material layer 15 is a slag wool layer. The sound-insulating material layer is peak sponge 131 . The sound-insulating material layer is a foam rubber layer. One of the side plates 16 is provided with a control panel mounting seat 3 , and the contr...

Abstract

The invention relates to the field of diesel generators, in particular to a soundproof outer cover of a mute generator set. The soundproof outer cover comprises a soundproof outer cover body arrangedoutside the generator set in a covering mode. The soundproof outer cover body is of a double-layer structure composed of an inner layer plate and an outer layer plate, thus a closed cavity is formed between the inner layer plate and the outer layer plate, the cavity is vacuumized to improve the soundproof effect of the soundproof outer cover, meanwhile, a sound-attenuation material layer is arranged on the face, facing the generator set, of the inner layer plate, part of noise from the generator set is absorbed through the sound-attenuation material layer, noise absorbing of the sound-attenuation material layer is matched with sound insulation of a vacuum layer, thus the noise of the generator set is greatly lowered, and the mute purpose is achieved .

Description

technical field [0001] The invention relates to the field of diesel generators, in particular to a soundproof cover of a silent generator set. Background technique [0002] The box of the existing diesel generator is only used as the casing of the diesel generator, which plays an aesthetic and protective role, and cannot reduce the noise. At present, the commonly used way to reduce the noise of the diesel generator is to connect an external muffler, but it is affected by Due to the limitation of the noise reduction range, the noise reduction effect is not ideal, and the diesel generator still produces a lot of noise when it is working. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sound-proof enclosure for a silent generating set that can sufficiently reduce noise. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a sound-insulating...
