Noise-reducing door and window of transformer substation
The invention relates to a noise-reducing door and window of a transformer substation, relates to an environmental protection technology and discloses a sound-absorbing sound-insulating door and window. The sound-insulating window comprises a row window 1, a sound-absorbing curtain 2 and a curtain frame 3. The curtain frame 3 is additionally arranged on the outer wall surface of the row window 1 at the top of an existing house wall. The sound-absorbing curtain 2 is arranged in the curtain frame 3. Noise transmitted from the window is absorbed by the head-on blocking sound-absorbing curtain 2.The sound-insulating door is characterized in that a sound-absorbing layer 6 is arranged on the inner side surface of an existing house door 5, and a sealing strip is arranged at a seam opening of a door seam for preventing the noise from being leaked. The sound-absorbing curtain 2 and the sound-absorbing layer 6 are porous foamed plastic cores and can easily absorb the noise. The noise-reducing door and window disclosed by the invention has the advantages that the noise is reduced from a source, and the noise cannot be reduced in a large range after the noise is diffused; the measures are simple and easy to implement; and the noise-reducing mechanism effect of absorbing sound wave energy is obvious. The noise-reducing door and window disclosed by the invention is used for reducing the noise of a workshop.
变电站的降噪门窗涉及环保技术，公开了一种吸音的隔音门、隔音窗。隔音窗由排窗1、吸音簾2、簾架3组成。在现行房墙顶部的排窗1外墙面加装簾架3。簾架3内装有吸音簾2。从窗户透出的噪音，被迎面阻挡的吸音簾2吸收。隔音门是现行房门5内侧面装有吸音层6，门缝子口有密封条，以防噪音外泄。吸音簾2、吸音层6均是多孔性发泡塑料芯，很容易吸收噪音。降噪于源，不使噪音扩散后在大范围内去降噪；措施简单易行；吸收声波能量的降噪机理效果明显。用于工房降噪。
