Изобретение относитс к области гидротехнического строительства и предназначено дл перевода молоди рыб из верхнего бьефа гидроузла в нижний.The invention relates to the field of hydraulic engineering and is intended to transfer fry of young fish from the downstream to the lower unit.
Известен рыбоход лоткового типа с неполными поперечными перегородками - гасител ми скорости течени воды 1.The fish passage of a trough type with incomplete transverse partitions — water flow rate quencher 1 is known.
Недостатком известного устройства вл етс то, что при скате через плотину выклюнувша с из отложенной икры молодь в лотке травмируетс , гибнет.A disadvantage of the known device is that when the raft goes over the dam, the young in the tray are discharged from the deferred calf and are injured and die.
Целью изобретени вл етс уменьшение травмировани молоди рыб при переводе из верхнего бьефа гидроузла в нижний.The aim of the invention is to reduce the injury of juvenile fish when moving from the headwaters to the lower unit.
Указанна цель достигаетс тем, что лоток выполнен с двум каналами, расположенными один над другим и разделенными перегородкой, в которой установлены на горизонтальных ос х vionacTHbie колеса, причем нижний канал соединен с верхним бьефом гидроузла посредством трубопровода с задвижкой, на перегородке в местах Зстановки лопастных колес расположены уплотнительные экраны.This goal is achieved by the fact that the tray is made with two channels located one above the other and separated by a partition in which they are mounted on horizontal axes of the vionacTHbie wheel, the lower channel is connected to the upper unit of the hydroelectric complex through a pipeline with a valve, on the partition in places of the blade wheels located sealing screens.
На чертеже изображено устройство, общий вид.The drawing shows the device, the overall appearance.
У плотины 1 находитс лоток 2 с двум расположенными один над другим каналами , разделенными перегородкой 3, в которой установлены лопастные колеса 4. Нижний канал лотка 2 соединен с верхним бьефом гидроузла трубопроводом 5 с задвижкой 6.At the dam 1 there is a tray 2 with two channels located one above the other, separated by a partition 3, in which paddle wheels 4 are installed. The lower channel of the tray 2 is connected to the upper unit of the hydroelectric complex by a pipeline 5 with a valve 6.
На перегородке в местах установки лопастных колес 4 предусмотрены уплотнительные экраны 7, предотвраш,ающие поступление воды из одного канала лотка в другой.Sealing screens 7 are provided on the partition in places where blades 4 are installed to prevent water from entering from one channel of the tray to another.
Устройство работает следуюш им образом .The device works in the following way.
Движение воды в верхнем канале лотка 2 вызывает враш,ение лопастных колес 4 против часовой стрелки. Однако поток воды вThe movement of water in the upper channel of tray 2 causes the vane wheel 4 to turn counterclockwise. However, the flow of water in
нижнем канале создает на лопатках колеса 4 тормоз щий момент, на преодоление которого расходуетс часть энергии потока в верхнем канале. Величина тормоз щего момента , а следовательно, и степень гашени The lower channel creates a braking moment on the blades of the wheel 4, to overcome which part of the flow energy in the upper channel is expended. The magnitude of the braking torque, and hence the degree of damping
