High-speed rail sound barrier top end noise reduction device
The invention belongs to the technical field of sound barriers, and discloses a sound barrier top end noise reduction device which comprises a base, a bottom plate, a longitudinal plate and an inclined plate. The base is provided with a groove and can be mounted on the sound barrier main body to connect the sound barrier main body with the top end structure; the bottom plate is fixedly connected with the base, and grooves for mounting the inclined plate and the longitudinal plate are formed in the bottom plate; the longitudinal plate is mounted in the middle of the bottom plate; the inclined plates are uniformly distributed on the bottom plate, are obliquely mounted and intersect with the longitudinal plates to form a comb-tooth-shaped structure; the outer edges of the longitudinal plate and the inclined plate are respectively provided with a rectangular tooth-shaped structure; a comb-tooth-shaped structure formed by the inclined plates and tooth-shaped structures on the edges of the longitudinal plates and the inclined plates can weaken transmission of aerodynamic noise, improve the sound field at the top of the sound barrier when a train passes through the sound barrier at a high speed, greatly weaken sound wave energy transmitted to the rear side of the sound barrier, improve the noise reduction effect of the high-speed rail sound barrier and improve the noise reduction effect of the high-speed rail sound barrier. And the width of the whole device can be equal to that of a sound barrier body, the weight is light, and good applicability is achieved.
本发明属于声屏障技术领域，且公开了一种声屏障顶端降噪装置，装置包括底座、底板、纵板和斜板；所述的底座带有凹槽，能够安装在声屏障主体上，连接声屏障主体与顶端结构；所述的底板与底座固连，其上有安装斜板和纵板的沟槽；所述的纵板安装在底板中间位置；所述的斜板均匀分布在底板上，斜向安装，与纵板相交，构成梳齿状结构；所述的纵板和斜板外边缘均有矩形齿状结构；本装置中斜板所构成的梳齿状结构以及纵板和斜板边缘的齿状结构能够减弱气动噪声的传播，改善列车高速通过时声屏障顶部声场，大大减弱传播到声屏障后侧的声波能量，从而提高高铁声屏障的降噪效果，且整个装置的宽度能够与声屏障屏体的宽度相当，质量较轻，具有良好的适用性。
