Omni-directional ventilation railway sound barrier capable of achieving broadband sound insulation
The invention relates to the field of railway noise reduction, in particular to an omni-directional ventilation railway sound barrier capable of achieving broadband sound insulation. The system comprises a sound barrier module; the sound barrier module comprises an inner cylinder part, a plurality of spiral plate parts and an outer cylinder part, the inner cylinder part and the outer cylinder part are each of a cylindrical structure, a center shaft is horizontally arranged, the inner cylinder part, the spiral plate parts and the outer cylinder part are coaxially distributed from inside to outside and integrally connected, and the multiple spiral plate parts are evenly arranged around the center shaft of the inner cylinder part; a spiral channel is formed between the outer circumferential face of the inner cylinder part, the inner circumferential face of the outer cylinder part and every two adjacent spiral plate parts. The noise reduction effect is good, the ventilation performance is good, and the self-weight is small.
本发明涉及铁路降噪领域，具体为一种可实现宽频隔声的全向通风铁路声屏障。其包括声屏障模块；声屏障模块包括内筒部、螺旋板部和外筒部，内筒部和外筒部均为圆筒形结构，且中心轴水平设置，内筒部、螺旋板部和外筒部由内之外同轴分布且一体连接，螺旋板部绕内筒部中心轴均匀设置有多个，内筒部外周面、外筒部内周面以及相邻两螺旋板部之间形成螺旋通道。本发明降噪效果好、通风性能好且自重小。
