摘要
为保证水电站水下设施的安全,解决人类与水下物种间的相互干扰等问题,保护生态并可持续发展,开发一套带宽为20 Hz^10 k Hz,声压级最大可达180 d B的水下发生器系统,并在码头进行了声波驱鱼的试验,通过试验数据,表明声波驱鱼效率良好,大鱼的驱离率达70%,鱼群的驱离率达50%。试验结果表明声波驱鱼技术具有一定的市场应用前景和推广价值。
In order to ensure the safety of underwater facilities in hydropwer station,solve the problems of mutual interference between humans and underwater species,protect the ecology and maintain ecological balance,develop a set of underwater generator system with a bandwidth of 20 Hz^10 kHz and the level of sound pressure up to 180 dB.At the pier,test of Sonic-driven fish has been carried out.The experimental data shows that the efficiency of driving fish by sound is good,the rate of driving fish reached 70%,and the rate of driving shoal of fish reached 50%.The experiment shows that the technology of driving fish by sound has certain value of market application and promotion.
