Automatic openable totally-closed sound barrier
The invention discloses an automatic openable totally-closed sound barrier, and relates to the technical field of totally-closed sound barriers, a driven gear can drive an adjusting gear to rotate, the adjusting gear can drive a rack to deflect in the rotation process, and the rack can drive four fluted discs to rotate in the deflection process. The fluted discs drive the sound barrier plates to rotate through the connecting shafts, the sound barrier plates on the two sides are opened in a splayed shape, and when high-frequency, high-wind-speed and large-wind-pressure crosswind and pulsating wind pressure generated by running of a high-speed train act on the totally-closed sound barrier, incoming flow wind penetrates through the totally-closed sound barrier through gaps between the sound barrier plates and the mounting holes, so that the totally-closed sound barrier is formed. The area of the windward side of the totally-closed sound barrier is reduced, the wind pressure on the whole totally-closed sound barrier is reduced, the stress of the sound barrier steel structure and the supporting assembly is reduced, the strength and performance of the whole totally-closed sound barrier are guaranteed, the railway traffic safety is guaranteed, and the situation that the subsequent operation and maintenance cost is increased due to the fact that the totally-closed sound barrier is damaged is prevented.
本发明公开了一种自动可开式全封闭声屏障，涉及全封闭声屏障技术领域，通过从动齿轮能够带动调节齿轮旋转，调节齿轮旋转的过程中能够带动齿条发生偏转，齿条偏转的过程中能够带动四个齿盘旋转，齿盘则通过连接轴带动声屏障板旋转，两侧的声屏障板呈八字形张开，在高频率、高风速及大风压的横风和高速列车行驶产生的脉动风压作用在全封闭声屏障上时，来流风通过声屏障板与安装孔之间的间隙穿过全封闭声屏障，减小全封闭声屏障迎风面面积，使整个全封闭声屏障受风压减小，减小声屏障钢结构以及支撑组件的受力，保证整个全封闭声屏障的强度以及性能，铁路交通安全性得到保障，防止全封闭声屏障损坏从而增加后续运维成本。
