Sound-absorbing structure and decoration method of container-type silent box body

Abstract

The invention relates to a container type mute box body sound attenuation structure and a decoration method thereof. The container type mute box body sound attenuation structure comprises a beam, a corrugated board is welded at the outer end of the side face of the beam, and an inner and outer frame assembly is welded at the inner end of the side face of the beam. According to the structure of the inner and outer frame assembly, an outer frame welded at the inner end of the side face of the beam is included, an inner frame is welded in the outer frame, the outer frame and the inner frame are both of a right angle type structure, the longitudinal folding edge of the outer frame and the longitudinal folding edge of the inner frame are welded together at a welding point in advance, a gap is reserved between the horizontal folding edge of the outer frame and the horizontal folding edge of the inner frame, a perforated plate is inserted in the gap, and the perforated plate is fixed on a bracket through a rivet. A space defined by the beam, the corrugated board, the inner frame and the perforated plate is filled with rock wool, rock wool non-woven fabric is laid on the outer surface of the rock wool, and the rock wool and the rock wool non-woven fabric are anchored to the inner side face of the corrugated board. The container type mute box body sound attenuation structure is compact in structure, easy and convenient to manufacture and mount, neat and attractive in surface, saving in labor and material, and good in noise reduction effect.

Description

technical field [0001] The invention relates to a container-type silent box device of a generator set, in particular to a noise-absorbing structure and a decoration method of a container-type silent box body for a generator set. Background technique [0002] Containerized silent generator sets have been widely used in field engineering, rescue, rescue and other fields. As an important part of the containerized silent generator set, the sound-absorbing structure and decoration method of the silent box directly affect the silent performance of the generator set, as well as the control of manufacturing quality and cost. The sound-absorbing structure and installation method of the box of the container-type silent generator in the prior art are not perfect. The rock wool frame and the box beam are intermittently welded on the outside; the porous plate is placed outside the frame, and then the burrs around the mesh plate are pressed with aluminum alloy strips, and riveted to the ...

AI Technical Summary

Problems solved by technology

This kind of sound-absorbing structure of the box is unreasonable, the installation method is labor-intensive, the production efficiency is low, and the joints are not beautiful.
