摘　　要：水利枢纽项目引水过程中,进水口拦鱼设施采用的细目拦鱼网,具有较大的阻水面积,易被污物和鱼类堵塞,影响进水口的正常取水,另外检修清理也不方便。电栅是有效、安全且先进的拦鱼、导鱼设施,通过布置电栅来产生无形的水下电场,能从根本上克服有形机械性拦鱼设施的局限性。随着国家对工程建设项目中生态保护的重视,水生生物保护措施也会越来越多、越来越完善,鉴于以往水利水电工程中该类项目较少,以马岭水利枢纽工程电赶拦鱼系统为例,对其结构、安装、运行进行介绍。In the diversion process of water conservancy complex project, the detailed fishing net used in the intake fish-holding facility has a large water-holding area, which is easily blocked by dirt and fish, affecting the normal water intake of water intake, and is also inconvenient for overhaul and cleaning. Electric grille is an effective, safe and advanced fishing and guiding facility. By arranging electric grille to generate invisible underwater electric field, the limitation of tangible mechanical fishing facility can be fundamentally overcome.With the national attention to ecological protection in engineering construction projects, more and more aquatic biological protection measures will be taken and improved. In view of the small number of such projects in hydraulic and hydropower projects in the past, this paper takes the electric catching and blocking system of Maling Hydraulic Complex Project as an example to introduce its structure, installation and operation.
