FIELD: construction.SUBSTANCE: floating water intake comprises a water receiving chamber 1 with water receiving windows 2 and overflow windows 3, a suction chamber 4 with first stage pumps 5. The water receiving chamber 1 and the suction chamber 4 are made in the form of a float with an air chamber 6 in the lower part of the water intake structure and are placed in a reservoir 7, filled with water 8 and installed on the bottom of a surface spring 9. Equipment of the water intake structure in the form of a float in a reservoir makes it possible to use it under high speed of flow and variations of water levels in the water source, which improves operating qualities of the water intake structure. Maintenance of the permanent water level in the suction chamber reduces energy inputs for pumping water during operation of a water receiver.EFFECT: in process of water intake at controlled elevations from a surface spring there are less sediments arriving to a water receiving chamber, and it is possible to clean water receiving holes, which increases reliability of operation of a water intake structure.3 dwg |
