Abstract

This utility model relates to the field of building engineering technology and discloses a noise reduction device for municipal building engineering, including a noise reduction plate. Positioning strips are fixedly connected to both sides of the noise reduction plate, and support columns are movably installed on both sides of the noise reduction plate. Fixing grooves are fixedly connected to the outer surface of the support columns, and an adsorption plate is fixedly connected to one side of the noise reduction plate. This utility model has the following advantages and effects: When dust occurs, the nanofiber dust-absorbing net can be quickly disassembled and connected to the water pipe and nozzle. The increased weight of the water mist and the adsorption of the nanofiber dust-absorbing net improve dust filtration, solving dust pollution while reducing noise. When the nanofiber dust-absorbing net needs cleaning, it can be quickly removed for external rinsing. Simultaneously, the noise reduction plate is connected by a plug-in method, with a sealing strip between the positioning strip and the fixing groove, improving the sealing during installation and ensuring a stable connection. When damage occurs and replacement is needed, it can be disassembled efficiently.
