Sound insulation and noise reduction device for wall-penetrating pipeline in hydropower plant

Abstract

The invention discloses a sound insulation and noise reduction device for a wall-penetrating pipeline in a hydropower plant. The sound insulation and noise reduction device comprises a sound insulation and noise reduction device body, wherein the sound insulation and noise reduction device body consists of a sound insulation and noise reduction plate and a mounting frame; the sound insulation andnoise reduction plate is vertically arranged and embedded into a channel opening of a wall body through the mounting frame; the sound insulation and noise reduction plate consists of an upper plate body, a middle plate body and a lower plate body; the upper plate body, the middle plate body and the lower plate body are sequentially overlapped; a through hole A convenient for a large pipeline to pass through is formed between the upper plate body and the middle plate body; a through hole B convenient for a small pipeline to pass through is formed between the middle plate body and the lower plate body; and a rubber buffer sleeve is arranged in the through hole A. Compared with the prior art, the sound insulation and noise reduction device for the wall-penetrating pipeline is designed for a wall-penetrating channel in the hydropower plant house, so that the working areas are effectively isolated, the noise in a hydraulic turbine house is prevented from transmitting out to influence otherworking areas, the mounting and the dismounting are very convenient, and the safe operation of an original pipeline is not influenced.

Description

technical field [0001] The invention relates to a power plant facility, in particular to a sound insulation and noise reduction device for a wall-penetrating pipeline of a hydropower plant. Background technique [0002] Hydropower plants are large-scale electrical equipment, and the connection between equipment often needs to be connected through wall pipes. Because of the frequent maintenance of pipelines and the increase of pipelines, if only holes are drilled in the wall for pipeline insertion, installation, and maintenance etc. are very inconvenient, and it is easy to damage the pipeline, so the usual practice in hydropower plants is to directly open a channel opening on the wall, and the pipeline passes through the channel opening to connect to the corresponding equipment (see figure 1 ). However, some equipment in the hydropower plant will generate a lot of noise during operation (such as the turbine room), and the passage openings are closed, which is not convenient ...

AI Technical Summary

Problems solved by technology

However, some equipment in the hydropower plant will generate a lot of noise during operation (such as the turbine room), and the passage openings are closed, which is not convenient for sound insulation, which seriously affects the working environment of other workshops
