Load shedding sound barrier unit and sound barrier thereof
The invention provides a load shedding sound barrier unit and a sound barrier thereof. The load shedding sound absorption screen body comprises at least one load shedding unit structure arranged in the vertical direction, and an upper screen body and a lower screen body which are adjacent to the load shedding unit structure. The load shedding unit structure comprises a left screen body, a right screen body and a load shedding structure located between the left screen body and the right screen body. The load shedding structure comprises a rotating wheel and an outer cylinder. The rotating wheel comprises a rotating shaft and at least three impellers, the two ends of the rotating shaft are connected with the left screen body and the right screen body respectively and can rotate freely, and the impellers are evenly arranged on the rotating shaft in a surrounding mode. The outer cylinder is fixed to the upper screen body and the lower screen body which are adjacent to the outer cylinder, each screen body is provided with an arc-shaped attaching face matched with the outer cylinder, and the gap between the outer end of the impeller and the inner side of the outer cylinder is not larger than 2 mm. The connecting surfaces of the upper and lower adjacent screen bodies are bent arc-shaped binding surfaces; the diameter of the outer cylinder is at least 200 mm, and the outer cylinder is provided with an end air opening and a surface air opening. After wind pressure acts on the two-end tuyeres and the surface tuyeres, the impeller is pushed to rotate around the rotating shaft, the pressure is converted, and the wind load is effectively reduced.
本发明提供一种减载声屏障单元及其声屏障。减载吸声屏体包括沿竖向方向设置的至少一个减载单元结构、与其相邻的上屏体和下屏体；减载单元结构包括左屏体、右屏体和位于二者之间的减载结构，减载结构包括转轮和外圆筒；转轮包括转轴和至少三片叶轮，转轴的两端分别与左右屏体相连接且可自由转动，叶轮均匀环绕设置于转轴上；外圆筒固定于与其相邻的上屏体和下屏体上，屏体具有与外圆筒适应的弯弧型贴合面，叶轮外端与外圆筒内侧的间隙不大于2mm；上下相邻的屏体连接面为弯弧型贴合面；外圆筒的直径至少为200mm，外圆筒具有端部风口和表面风口。风压作用在两端风口和表面风口后，推动叶轮围绕转轴旋转，将压力转化，有效降低风荷载。
