Noise reduction device for site construction
The invention relates to the technical field of noise reduction devices, in particular to a noise reduction device for site construction, which comprises a noise reduction box, a sound absorption cylinder and a sound discharge flow channel, the sound absorption cylinder and the sound discharge flow channel are arranged on the noise reduction box, the sound absorption cylinder is communicated with the sound discharge flow channel, and the noise reduction device further comprises a guide element arranged on the noise reduction box, the guiding element is used for guiding noise to enter the sound absorption cylinder and is communicated with the sound discharging flow channel; the plurality of sub-runners are connected between the sound absorption cylinder and the sound discharge runner; the number of the noise reduction systems is the same as that of the sub-runners, and each noise reduction system is arranged in the corresponding sub-runner; the step-by-step sound discharge system is arranged between the guide element and the sound discharge flow channel; weak sound wave units are discharged out of the noise reduction box step by step through the step-by-step sound discharge system, collection of the sound wave units is avoided, noise reduction treatment is accurately and effectively carried out on sound generated on a construction site, and the noise reduction effect is better compared with a traditional mode that a sound absorption plate is independently adopted.
本发明涉及降噪装置技术领域，更具体地说，是一种现场施工用降噪装置，包括降噪箱、吸音筒以及排音流道，所述吸音筒和排音流道均设置在降噪箱上，所述吸音筒和排音流道连通，还包括：引导元件，设置在所述降噪箱上，用于引导噪音进入吸音筒，所述引导元件与排音流道连通；分流道，数量为若干个，所述分流道连接在吸音筒和排音流道之间；降噪系统，数量与分流道的数量相同，每个所述降噪系统设置在分流道内；以及分步排音系统，设置在引导元件与排音流道之间；通过分步排音系统将虚弱后的声波单元进行分步排出降噪箱，避免声波单元之间汇集，确而有效的对施工现场产生的声音进行降噪处理，相对于传统的单独采用吸音板降噪的效果更佳。
