Abstract
(DE)
Eine Vorrichtung zum Belüften von Gewässern, umfassend eine Schwimmplattform (19), einen auf der Schwimmplattform (19) abgestützten Motor (15), ein mit dem Motor (15) gekoppeltes Getriebe (16), dessen Abtriebswelle als Hohlwelle (17) ausgebildet ist, ein Gebläse zum Zuführen von Luft durch eine damit verbundene Luftzuführleitung (18), wobei die Luftzuführleitung (18) an das eine Ende (E1) der Hohlwelle (17) angeschlossen ist, eine mit dem anderen Ende (E2) der Hohlwelle (17) gekoppelte hohle Rührwelle (1), einen am freien Ende der sich etwa vertikal erstreckenden Rührwelle (1) angebrachten Rührkörper (K), wobei der Rührkörper (K) als Hohlkörper ausgebildet ist und einen zentralen Durchbruch (3) zum Durchführen von durch die Rührwelle (1) zugeführter Luft sowie eine Vielzahl von Luftaustrittsöffnungen (14) aufweist.
(EN)
An apparatus for aerating bodies of water, comprising a floating platform (19), a motor (15) supported by the floating platform (19), a transmission (16) which is coupled to the motor (15) and whose output shaft is in the form of a hollow shaft (17), a fan for supplying air through an air supply line (18) connected thereto, wherein the air supply line (18) is connected to one end (E1) of the hollow shaft (17), a hollow stirring shaft (1) coupled to the other end (E2) of the hollow shaft (17), a stirrer (K) affixed to the free end of the approximately vertical stirring shaft (1), wherein the stirrer (K) is designed as a hollow body and has a central opening (3) through which air supplied by the stirring shaft (1) can pass, and a multiplicity of air outlet openings (14).
(FR)
L’invention concerne un dispositif d’oxygénation des eaux comprenant une plateforme flottante (19), un moteur (15) soutenu sur la plateforme flottante (19), une transmission (16) accouplée au moteur (15) et dont l’arbre de sortie se présente sous forme d’arbre creux (17), une soufflante destinée à acheminer de l’air à travers une conduite d’alimentation air (18) reliée à ladite soufflante, la conduite d’alimentation en air (18) étant raccordée à une extrémité (E1) de l’arbre creux (17), un arbre d’agitation (1) creux accouplé à l’autre extrémité (E2) de l’arbre creux (17), un corps d’agitation (K) monté à l’extrémité libre de l’arbre d’agitation (1) qui s’étend approximativement verticalement, le corps d’agitation (K) se présentant sous forme de corps creux, et un passage (3) central destiné à faire passer l’air acheminé à travers l’arbre d’agitation (1) ainsi qu’une pluralité d’ouvertures de sortie d’air (14).
