HYDRAULIC PLANT FOR PURIFICATION OF SHALLOW WATER BODIES FROM SEDIMENT Russian patent published in 2021 - IPC E02F3/88 

FIELD: hydromechanization.

SUBSTANCE: invention relates to the field of hydromechanization and is designed to remove sediment hydraulically from shallow water bodies, fish catchers, pumping station forecourts. The proposed hydraulic floating installation for sediment removal including a pontoon 1 with a support frame 27 and a boom 10, at the submerged end of which there is a hydraulic ripper 8 with a soil intake device 7 and a jet device 4. The upper part of the pontoon has a centrifugal dredger 2 connected to a diesel generator 21 with an electric cable 25, with a suction line 20 through a valve 11 and with a pressure line 19, a working centrifugal pump 3, connected to the jet apparatus 4 by a working line 9 with a valve 30, a starting line and an ejector 6 through a line 28 with a valve 16, a centrifugal pump 5 connected to the reservoir 22 and the ejector 6 through the valve 15. The submersible part of the pontoon 1 contains a jet pump 17 connected to the working pipeline 9 by means of a pipeline with a valve 14 and an outlet pipeline with a valve 13, and a propeller nozzle 26 connected to the slurry supply pipeline 24 by means of a pipeline with a valve 29. In this case the slurry supply line 24 is connected to the jet apparatus 4 and to the working line 18 through the suction line 20 with the valve 12.

EFFECT: increased operational reliability, simplified design, the ability to operate the installation without the use of mechanical devices is provided.
