Dispositif d'aspiration pour de grands corps d'eau artificiels

La présente invention concerne un dispositif d'aspiration flexible pour aspirer des fragments de glace du fond de grands corps d'eau artificiels présentant des surfaces supérieures à 10 000 m et des fonds recouverts de revêtements en plastique qui n'ont pas de systèmes de filtration centralisés. Ledit dispositif est apte à nettoyer une surface de fond de grands corps d'eau artificiels à une vitesse de nettoyage de surface de 325 000 ft A suctioning device for suctioning impurities from the bottom of large artificial water bodies is provided. The suctioning device includes a flexible sheet configured to provide a structural frame; a plurality of first brushes depending from the sheet; a plurality of middle brushes; a plurality of lateral brushes; a plurality of suction points; a plurality of wheels configured to provide secondary support when the brushes are worn out; a plurality of collectors configured to gather the suctioned water into 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, wherein a rate of the bottom water flow entering the suctioning device is the same or higher than a rate of water flow suctioned by an external pumping system.
