Abstract

Изобретение относитс  к области гидротехники, предназначено дл  использовани  и нысоконапорных плотинах на рыбохоз йственных реках и  вл етс  усовертенствованием известного устройства по а.с. № 1280099.Цель изобретени  - уменьигение травмировани  и гибели молоди рыб при спуске через высоконапорную плотину. Устройство дл  спуска молоди рыб через плотину включает трубу-конфузор 1, соедин ющую верхний бьеф 2 и нижний бьеф 3 плотины 4. На выходном отверстии трубы-конфузора 1 жестко установлен гаситель 7 энергии потока,состо щий из колец 8 разного диаметра,имеющих односторонние расширени  9 Гаситель 7 установлен горизонтально, а кольца 8 размещены вдоль его оси с возрастанием их диаметров в сторону от выходного отверсти  трубы-конфузора , жестко скреплены друг с другом и направлены расширени ми 9 в сторону выходного отверсти  трубы-конфуэо- ра 1 . При работе устройства выход щий из трубы-конфу ора 1 в нижний бьеф 3 поток с рыбой смешиваетс  с водой, поступающей в щели мезеду кольцами 8 и расширени ми 9, и постепенно замедл етс  до допустимых скоростей. 2 ил. о 9 (ЛThe invention relates to the field of hydraulic engineering, is intended for use and high-pressure dams on fishery rivers, and is an improvement of the known device along. No. 1280099. The purpose of the invention is to reduce the injury and death of young fish when descending through a high-pressure dam. A device for lowering fish fry through a dam includes a confuser pipe 1 connecting the upper pool 2 and lower pool 3 of the dam 4. At the outlet of the pipe confuser 1, a flow energy extinguisher 7 is rigidly installed, consisting of rings 8 of different diameters having unilateral extensions 9 The damper 7 is mounted horizontally, and the rings 8 are placed along its axis with an increase in their diameters away from the outlet hole of the pipe confuser, rigidly fastened to each other and directed by extensions 9 toward the outlet opening of the pipe confueor a 1. During operation of the device, the flow from the fish coming out of the pipe-konfu ora 1 to the downstream 3 is mixed with the water entering the cracks of the meseda by the rings 8 and the extensions 9, and gradually slows down to acceptable speeds. 2 Il. about 9 (L
