воды в энерговодосбросной тракт 2. Далее резко открывают низовой затвор 7, в результате чего вода Сбрасываетс  через низовое отверстие 6 и на участке ответвлений возникают крупные волны. Мусор, накопившийс  на решетках, при воздействии образовавшихс  волн приподнимаетс  над решетками, подхватываетс  потоком и через сбросное отверстие 6 уноситс  в Ш-1ЖНИЙ бьеф. Очередность операций повтор етс  до полной очистки решеток 4 от накопившегос  мусора . Предлагаемый способ гидравлической очистки сороудерживаюших решеток гидроэлектростанций позвол ет более эффективно и за короткий срок производить очистку решеток, что значительно снижает воз.можность возникновени  аварийных ситуаций. Формула изобретен и   Способ гидравлической очистки сороудерживающих решеток, преимущественно иодземных гидроэлектростанций с энерговодосбросным трактом, имеюши.м ответвлени  турбинных водоводов, и установленными на них затворами , заключающийс  в с.мыве накопившегос  на решетках мусора путем пропуска промывного расхода через энерговодосбросиой тракт, о т л и чающийс  тем, что, с целью повышени  эффективности очистки решеток , при пропуске промывного расхода нрекращают подачу воды в турбинные водоводы и маневрируют затворами с образован1ием волн возмзщени  на участке ответвлений турбинных водоводов.

Then, the downstream shutter 7 is sharply opened, as a result of which the water is discharged through the downhole 6 and large waves appear in the branch section. The garbage accumulated on the grids, under the influence of the formed waves, rises above the grids, is picked up by the flow and through the discharge opening 6 is carried away into the SH-1 th bay. The sequence of operations is repeated until the grids 4 are completely removed from the accumulated debris. The proposed method of hydraulic cleaning of trash grids of hydroelectric power plants allows cleaning grids more efficiently and in a short period of time, which significantly reduces the possibility of emergency situations. The formula was invented and the Method of hydraulic cleaning of trash grids, mainly of hydropower plants with a power drainage tract, having branches of turbine conduits, and gate valves installed on them, consisting of drainage water accumulated on the debris grids by passing the flushing flow through the waste water supply lines of the accumulated tracts of waste accumulated on the debris grids by passing the flushing flow through the waste water supply lines and the accumulated tracts of waste water accumulated on the debris grids by passing the flush flow through the waste water supply lines. due to the fact that, in order to increase the efficiency of cleaning the grids, when skipping the washing flow rate, they stop the flow of water to the turbine water lines and maneuver the valves with development of waves of compensation in the section of branches of turbine pipelines.
