METHOD OF CREATION OF ADJUSTABLE FREE FLOWING WATER FLOW AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC E02B7/18 E02B13/00 

FIELD: power industry.

SUBSTANCE: invention relates to hydraulic engineering, specifically to creation of the water flow and its control using pipes to drive the hydraulic turbines, devices of water systems, and protection of fill dams against washaway. To create water flow the siphon is used, at its ends the gates are installed, and in its top point a hole is made closed by the tight plug. The siphon intake end is lowered in the source water reservoir, and drain end is inserted in beginning of the distribution pipe, its internal diameter is selected higher then outside diameter of the siphon pipe. For the water flow start gates are closed in series, the siphon is filled with water up to plug, hole is tightly closed by plug, and gates are opened. The created water flow is directed in the required or safe for people and environment direction via the distribution pipes, trays or other water ways. The dam protection against washaway (in case of the water overflow over the dam) is performed by means of the siphon gates opening and water overflow over the siphon installed on the dam crest. Method is ensured using the device containing siphon with controlled gates in input and output ends, and with hole in its top point closed by tight plug, distribution pipes, buffer or water discharge devices, trays and water ways. To ensure the required higher intensity of the water flow the single flows of several specified devices installed in common or different source water reservoirs or acting water flows are combined in common rather powerful flow.

EFFECT: possibility of increasing of energy power with significantly lower specific and absolute expenses, and fill dams protection against washaway upon threat of dam pond overfilling.
