Suctioning device for large artificial water bodies

A suctioning device for suctioning a water volume from a bottom of large artificial water bodies, with surfaces larger than 10,000 m2, without centralized filtration systems, where the suctioning device is capable of cleaning at a surface rate of 325,000 ft2 per 24 hours (30,000 m2 per 24 hours) or more, the device comprising:

• a flexible sheet configured to provide a structural frame;
• a plurality of first brushes depending from the sheet;
• a plurality of middle brushes configured to redirect a bottom water flow into the first brushes;
• a plurality of lateral brushes configured to contain the bottom water flow within the suctioning device and avoid a re-suspension of the bottom water flow in the vicinity of the suctioning device;
• a plurality of suction points through which the bottom water flow is suctioned;
• a plurality of safety wheels configured to provide secondary support and avoid damage to the suctioning device when the first brushes, the middle brushes, and/or the lateral brushes are worn out and cannot provide a proper support or suction height of the suctioning device;
• a plurality of collectors configured to gather the suctioned bottom water flow and concentrate the suctioned bottom water flow into one or more external suction lines;
• a plurality of internal suction lines configured to conduit the suctioned bottom water flow from the plurality of suction points to the plurality of collecting means;
• and
• a coupling device connecting the internal suction lines and the collectors.
