Abstract

Изобретение относитс к гидротехника и может быть использовано в водосбросах высоконапорных ГЭС. Цель изобретени - повышение эффективности гашени . Дл сброса потока воды и гашени его энергии открывают затвор 1 и направл ют воду из верхнего бъефа в водосбросный лоток 4. Продольными вододелительными стенками, расположенными в лотке 4, поток воды раздел етс на два отдельных потока, один из которых поступает на верхний трамплин 9. С верхнего трамплина 9 поток отбрасывают в нижний бъеф 11 и сопр гают с поверхностью воды под углом более 30&deg; к горизонту с образованием устойчивых донных режимов. Другой отдельный поток по лотку 4 поступает на нижний трамплин 10, с которого воду отбрасывают в нижний бъеф 11 с обеспечением угла сопр жени с горизонтом воды менее 15&deg;, организу поверхностный режим сопр жени . Поток воды, сбрасываемый нижним трамплином 10, растека сь по поверхности нижнего бьефа 11, экранирует поток, сбрасываемый верхним трамплином. При этом обеспечиваетс эффективное гашение энергии потоков воды. 2 ил. (Л СFIELD OF THE INVENTION The invention relates to hydraulic engineering and can be used in the spillways of high-pressure hydropower plants. The purpose of the invention is to increase the efficiency of quenching. To discharge the water flow and quench its energy, open the shutter 1 and direct the water from the upper baff to the spillway tray 4. By longitudinal water walls located in tray 4, the water flow is divided into two separate streams, one of which goes to the upper springboard 9. From the upper springboard 9, the stream is thrown into the lower beef 11 and mated with the surface of the water at an angle of more than 30 ° C. to the horizon with the formation of sustainable benthic regimes. Another separate flow through the tray 4 enters the lower springboard 10, from which water is thrown into the lower beam 11 with the interface angle to the water horizon of less than 15 ° C, and the surface interface mode is organized. The flow of water discharged by the lower springboard 10, spreading over the surface of the lower pool 11, shields the stream discharged by the upper springboard. This ensures effective quenching of the energy of the water flows. 2 Il. (Ls

Claims

Claim

The method of quenching the energy of a water stream, including discharging the stream along the spillway of the dam having upper and lower springboards, dividing it into separate flows on the springboards, and dropping the flows through the upper and lower springboards into the lower pool, characterized in that, in order to increase the efficiency of 5 communications. the flow is discarded by the upper springboard at a greater distance from the dam and mated with the lower pool at an angle to the horizon of more than 30 °, and the lower springboard is discarded by a stream of water at a smaller distance from the dam and mated with the lower pool at an angle to the horizon of less than 15 °, organizing the surface pairing mode of this stream and impact with it on the surface of the downstream of the stream thrown by the upper springboard.
