Device and method for improving fish passing effect of fishway by utilizing fish oxygenotaxis characteristics
The invention particularly relates to a device and method for improving the fish passing effect of a fishway by utilizing fish oxygenotaxis characteristics, and belongs to the technical field of waterconservancy and hydropower engineering environments. The device comprises an aerator, a plurality of aeration units and a computer controller. The plurality of aeration units are arranged on the inner wall of the fishway at equal intervals; each aeration unit comprises an aeration pipeline, a plug-in automatic switch integrated valve and an exhaust pipe; the aeration pipelines are connected withthe exhaust pipes through the plug-in automatic switch integrated valves; the output end of the aerator is connected with the input ends of the aeration pipelines; the output ends of the exhaust pipesare connected with air stone; and the computer controller is connected with the aerator and the plug-in automatic switch integrated valves to control the oxygen output quantity of the aerator and theplug-in automatic switch integrated valves. An existing finished product oxygenation device can be directly used for luring fishes, the requirement for the long distance of the small bottom slope ofthe fishway can be met, the oxygenation range of the oxygenation device in water is indirectly widened, and the purpose of protecting fish resources is achieved.
本发明具体涉及利用鱼类趋氧性特征改善鱼道过鱼效果的装置及其方法，属于水利水电工程环境技术领域。装置包括增氧机、若干个增氧单元及计算机控制器；若干个增氧单元等距离间隔设置于鱼道内壁；增氧单元包括增氧管道、插入式自动开关一体阀及排气管；增氧管道与排气管通过插入式自动开关一体阀连接；增氧机的输出端与增氧管道的输入端连接；排气管的输出端连接气泡石；计算机控制器与增氧机和插入式自动开关一体阀相连，控制增氧机的氧气输出量和插入式自动开关一体阀。本发明既可以直接使用现有成品增氧装置诱鱼，又可以满足鱼道小底坡长距离的要求，间接延长增氧装置在水中的增氧范围，达到保护鱼类资源的目的。
