The invention relates to an assembly for cleaning a clarification basin of the type delimited by a wall and essentially comprising a chute formed by said wall, a bottom and a pouring blade; a siphon partition connected to the base of said blade by means of crosspieces; a scraper bridge associated with a gear motor and a drive wheel.

Les ensembles connus du genre en question, entraînés par le pont racleur, ne nettoient qu'une partie de la goulotte et non l'intégralité de celle-ci. Known assemblies of the genus in question, driven by the scraper bridge, clean only part of the chute and not all of it.

En outre, lesdits ensembles ne nettoient pas l'intérieur de la zone délimitée par la lame versante, les traverses et la cloison siphoïde. In addition, said assemblies do not clean the interior of the zone delimited by the pouring blade, the crosspieces and the siphon partition.

L'invention vise donc à réaliser un ensemble qui nettoie d'une part l'intégralité de la goulotte et d'autre part, en addition, l'intégralité de la zone susmentionnée. The invention therefore aims to achieve an assembly which cleans on the one hand the entire chute and on the other hand, in addition, the entire area mentioned above.

Elle concerne à cet effet un ensemble qui se caractérise essentiellement en ce qu'il comporte, en combinaison, un premier jeu de brosses adaptées pour nettoyer le fond de la goulotte et un deuxième jeu de brosses adaptées pour nettoyer les bords verticaux de ladite goulotte ; en ce que le premier jeu de brosses est solidaire d'un des côtés verticaux d'un premier parallélogramme articulé dont l'autre côté vertical est solidaire d'un mât vertical principal relié au pont racleur et en ce que le deuxième jeu de brosses est solidaire d'un des côtés verticaux d'un deuxième parallélogramme articulé dont l'autre côté vertical est relié au côté vertical, du premier parallélogramme articulé, porteur du premier jeu de brosses. To this end, it relates to an assembly which is essentially characterized in that it comprises, in combination, a first set of brushes suitable for cleaning the bottom of the chute and a second set of brushes suitable for cleaning the vertical edges of said chute; in that the first set of brushes is secured to one of the vertical sides of a first articulated parallelogram whose other vertical side is secured to a main vertical mast connected to the scraper bridge and in that the second set of brushes is secured to one of the vertical sides of a second articulated parallelogram, the other vertical side of which is connected to the vertical side, of the first articulated parallelogram, carrying the first set of brushes.

L'ensemble en question se caractérise également en ce qu'il comporte, en addition, un troisième jeu de brosses adaptées pour nettoyer, pour la première, le dessus des traverses et, pour les deux autres, les parois verticales en regard respectivement de la lame versante et de la cloison siphoïde et en ce que ledit troisième jeu de brosses est également solidaire du mât principal. The assembly in question is also characterized in that it comprises, in addition, a third set of brushes suitable for cleaning, for the first, the top of the crosspieces and, for the other two, the vertical walls opposite respectively of the pouring blade and the siphon wall and in that said third set of brushes is also integral with the main mast.
