Circular closed sound barrier
The invention provides a circular closed sound barrier which comprises two opposite arc-shaped columns arranged at intervals, unit plate inserting grooves are formed in the opposite sides of the two arc-shaped columns and extend in the extending direction of arcs, and bent arc type metal sound barrier unit plates are inserted into the two opposite unit plate inserting grooves. Each bent arc type metal sound barrier unit plate comprises a sound absorption module, a perforated panel is arranged on the side, facing a sound source, of the sound absorption module, the perforated panel is provided with a first perforated plate and a second perforated plate, the first perforated plate is located above the second perforated plate, the first perforated plate is gradually away from the sound absorption module from top to bottom in the height direction, the second perforated plate is gradually close to the sound absorption module, the lower end of the first perforated plate is connected with the second perforated plate, and a rain cover is arranged on the outer side of an orifice of a first hole formed in the first perforated plate. According to the invention, cotton volume weight increase, load increase and mildew aging caused by water seepage of the sound absorption modules can be avoided, the sound absorption effect is improved, and the service life is prolonged.
本发明提供一种圆形封闭式声屏障，包括两根相对且间隔设置的弧形柱体，两根弧形柱体的相对一侧设有单元板插装槽，单元板插装槽沿圆弧的延伸方向延伸，相对的两个单元板插装槽内插装有弯弧式金属声屏障单元板，弯弧式金属声屏障单元板包括吸声模块，吸声模块朝向声源的一侧设有穿孔面板，穿孔面板具有第一穿孔板、第二穿孔板，第一穿孔板处于第二穿孔板的上方，沿着高度方向自上而下，第一穿孔板逐渐远离吸声模块，第二穿孔板逐渐靠近吸声模块且第一穿孔板的下端与第二穿孔板连接，第一穿孔板上具有的第一孔的孔口外侧设有挡雨罩。根据本发明，能够杜绝吸声模块渗水导致棉容重增加、荷载增加、产生霉变老化，提高吸声效果及使用寿命。
