Elevator machine room noise reduction device and noise reduction method based on directional sound reflection sound absorption
The elevator machine room noise reduction device comprises a space sound absorber, a closed machine room, a traction system, a main machine beam and a noise reflection and absorption device, the space sound absorber is suspended on a ceiling of the closed machine room through expansion screws, and the main machine beam is connected to a floor boss of the closed machine room through bolts; the traction system is fixedly connected to a main machine beam through bolts, the noise reflecting and absorbing device is fixed to a floor of the closed machine room through foundation bolts, noise transmitted upwards in the closed machine room is absorbed by the space sound absorber, and part of noise transmitted downwards in the closed machine room is reflected by the noise reflecting device and is absorbed by the space sound absorber. And the other part is directly absorbed by the noise absorption device. The noise reduction device is novel in structure and convenient to implement, can be correspondingly adjusted according to different application scenes, and is rich in application scenes and high in applicability.
一种基于定向声反射吸声的电梯机房降噪装置及降噪方法，包括空间吸声体、封闭式机房、曳引系统、主机梁以及噪声反射与吸收装置，空间吸声体通过膨胀螺丝吊顶在封闭式机房天花板，主机梁通过螺栓连接在封闭式机房地板凸台上，曳引系统通过螺栓连接固定在主机梁上，噪声反射与吸收装置通过地脚螺栓固定在封闭式机房地板，封闭式机房内向上传播的噪声由空间吸声体吸收，向下方传递的噪声，一部分经噪声反射装置反射由空间吸声体吸收，另一部分则直接由噪声吸收装置吸收。本发明所涉及的降噪装置结构新颖，便于实施，可根据不同应用场景做出相应调整，应用场景丰富，适用性强。
