AI Technical Summary
Technical Problem
The low- and mid-frequency noise generated by containerized energy storage units during operation is difficult to suppress effectively, especially when space is limited, and traditional noise reduction methods are not very effective.
Method used
The noise reduction component is composed of two layers of glass wool of different thicknesses, combined with a targeted resonant sound absorption structure and a sound wave scattering structure, including perforated strips, cavities, glass wool, grids, and staggered through holes.
Benefits of technology
It significantly reduces the broadband noise of the energy storage cabinet and improves the quietness of the equipment during operation.

Abstract
The utility model belongs to the technical field of container type energy storage cabinets, and particularly relates to a glass wool structure noise reduction assembly for a container type energy storage cabinet, which comprises a rectangular metal outer frame pipeline, folded edges are arranged on two sides of the rectangular metal outer frame pipeline, and a plurality of grating units are mounted in the rectangular metal outer frame pipeline. Each grid unit comprises a metal square frame connected with the rectangular metal outer frame pipeline, a filling layer is arranged in the metal square frame, metal pressing strips are installed on the two sides of the metal square frame at intervals, a plurality of through holes are formed in the metal pressing strips, a lining layer is installed on the inner wall of the rectangular metal outer frame pipeline in a stud welding mode, and first threaded holes are formed in the folded edges. According to the device, by combining the double-layer glass wool with different thicknesses, the resonance sound absorption structure (the perforated pressing strip, the cavity and the glass wool) designed in a targeted mode and the sound wave scattering structure (the grating and the staggered through holes), the broadband noise of the energy storage cabinet is effectively restrained, and the noise generated during equipment operation is remarkably reduced.
