Fish escape prevention method suitable for water return gate of water delivery trunk canal in middle line of south-to-north water diversion
The invention provides a fish escape prevention device suitable for a water return gate of a middle line water delivery trunk canal in south-to-north water diversion, and belongs to the technical field of fish escape prevention devices.The fish escape prevention device comprises fish passing device assembly, fish blocking device assembly, a fish escape prevention device using method and device maintaining.The fish passing device is of a main body structure composed of a steel frame and a supporting frame, and a steel circular ring is fixedly welded to the steel frame; a fish passing hole is formed, the lower end of the fish passing device is provided with a supporting column and a steel ball, the fish blocking device is composed of a power grid, a connecting wire and a high-frequency pulse voltage device, a main structure composed of a steel frame and the supporting column enables the fish passing device to be high in stability, and the fish passing hole enables fishes staying near a water return gate to freely enter a main canal. The device can unload part of water flow impact force through supporting columns and steel balls at the lower ends of the fish passing device and the fish blocking device, the stability of the device is improved, the fishes can be far away from the fish blocking device and the fish passing device through a power grid and a high-frequency pulse voltage device, and the service life of the device is prolonged through device maintenance.
本发明提出一种适用于南水北调中线输水干渠退水闸的鱼类防逃装置，属于鱼类防逃装置技术领域，包括过鱼装置组装、拦鱼装置组装、鱼类防逃装置使用方法和装置维护，过鱼装置由钢架和支撑架组成主体结构，钢圆环固定焊接在钢架上，形成过鱼洞，过鱼装置下端设有支撑柱和钢球，拦鱼装置由电网、连接电线和高频脉冲电压器组成，钢架和支撑柱组成的主体结构使得过鱼装置稳定性强，过鱼洞的设计使得停留在退水闸附近的鱼类能自由进入到主干渠，过鱼装置和拦鱼装置下端的支撑柱和钢球使得该装置可卸载部分水流冲击力，增加了装置的稳定性，电网和高频脉冲电压器可以使得鱼类远离拦鱼装置和过鱼装置，装置维护增加了装置的使用年限。
