Abstract
Изобретение относитс к гидротехнике, а именно к водосбросным плотинам, возводимым на нерестовых реках. Цель изобретени - обеспечение пропуска рыбы из нижнего бьефа гидроузла в верхний. Водосбросна плотина низконапорного гидроузла состоит из водослива с широким порогом 1, струенаправл ющих бычков 2 и устаноь ленных между ними затворов 3. Бычки расположены в плане под углом один к другому с образованием чередующихс схсд - щихс и расход щихс водоспускных отверстий, а затворы 3 выполнены в виде щитов и установлены с возможностью воз вратно-поступательного перемещени в плоскости бычка. Скорости течени в нижнем бьефе за расход щимис бычками меньше, чем за сход щимис , и могуг быть приемлимыми дл пропуска рыбы из ниж него бьефз гидроузла в верхний. З.: .Ф-ЛУ. 2 ил. Н.Б.FIELD OF THE INVENTION The invention relates to hydraulic engineering, namely, to water discharge dams erected on spawning rivers. The purpose of the invention is to ensure the passage of fish from the downstream of the hydroelectric complex to the upper one. The spillway dam of a low-pressure hydraulic unit consists of a weir with a wide threshold 1, the buoys 2 which guide the bulls 2 and the gates 3 installed between them. The gobies are angled to each other in order to form alternating and diverging holes, and shields and installed with the possibility of reciprocating movement in the plane of the goby. Flow rates in the downstream for diverting gobies are lower than for converging, and can be acceptable for passing fish from the downstream to the upper hydroelectric station. Z .: .F-LU. 2 Il. Nb
