Active enhanced noise protection device along high-speed rail
The invention relates to an active enhanced noise protection device along a high-speed rail. The active enhanced noise protection device mainly comprises a screen body, an enhancement system and a control system, the screen body is a sound insulation base body, the screen body is of a split type and comprises a front screen body and a rear screen body, and a hole is formed in the middle of the screen body. The enhancement system comprises a water tank, a water pump, a diversion pipeline and other structures, the water tank, the water pump and the like are located underground, the diversion pipeline is installed in the middle of the screen body and can jet a high-density water curtain above the screen body to form an upper noise protection body, and the protection body has certain sound insulation capacity, is a flexible body and can achieve adjustment of air pressure on the two sides by changing the shape of the protection body. The control system comprises a microphone, a data processing unit and a driving unit and can automatically detect environmental noise signals and control the enhancement system to be opened and closed in real time. When the noise protection device is applied to noise abatement along the high-speed rail, a good noise reduction effect can be achieved, and meanwhile aerodynamic resistance borne by a train in the running process is reduced.
本发明涉及一种主动型增强式高铁沿线噪声防护装置，其主要包括屏体、增强系统以及控制系统。所述屏体为隔声基体，屏体为分体式，包含前屏体和后屏体，中间具有孔隙。增强系统包含水箱、水泵、分流管道等结构，水箱、水泵等位于地面以下，分流管道安装于屏体中间，可在屏体上方喷射高密度水幕，形成上方噪声防护体，该防护体具有一定的隔声能力，且为柔性体，可通过改变自身形状实现两侧气压调节。控制系统包含传声器，数据处理单元，驱动单元，可自主检测环境噪声信号，控制增强系统实时开闭。该种噪声防护装置应用于高铁沿线噪声治理时，可在获得良好降噪效果的同时，降低列车运行过程中受到的气动阻力。
