WATER RECEIVING STRUCTURE FOR WATER INTAKE FROM SURFACE SOURCES Russian patent published in 2009 - IPC E02B9/04 E03B3/04 

FIELD: construction.

SUBSTANCE: invention is related to water supply and may be used in systems of water supply from surface sources, where water level variances are usually observed with course of time, for instance during spring floods and low water. Water receiving structure for water intake from surface sources arranged in the form of bank water intake, comprises water receiving chamber with water-receiving windows, suction chamber with first stage pumps. Water receiving structure is arranged in the form of float with air chamber in lower part of water receiving structure and is fixed to vertical guide supports with the help of annular clutches. Equipment of bank water receiving structure in the form of float makes it possible to use only a single tier of water receiving openings during variations of water levels in water source.

EFFECT: increased operational properties of water receiving structure, which makes it possible to considerably reduce its dimensions, reduced energy inputs for water pumping in process of water receiver operation, reduced number of pumps supplying to water receiving chamber, which increases reliability of water receiving structure operation.
