Abstract

Dispositif de dégrilleur placé en proximité de la grille de protection caractérisé par :- un peigne (a) de grille est placé sur un bras articulé motorisé (b), par l’intermédiaire d’une liaison pivot (h), le bras (b) est lui-même tenu au-dessus de la canalisation (c) par une structure (d) qui n’encombre pas l’espace de canalisation,- le peigne (a) est placé sur le même degré d’inclinaison que la grille de protection des débris (e), de telle façon à toujours disposer de la même distance avec la grille (e), - le bras articulé motorisé (b) déplace le peigne (a) de haut en bas et de bas en haut de la grille (e) de protection des débris selon la cinématique suivante : = le peigne (a) descendant, il ne touche pas la grille (e) de protection et laisse un dégagement suffisant pour ne pas emporter vers le bas les débris reçus par la grille (e), = le peigne (a) remontant, il vient en liaison avec la grille (e) pour remonter les débris dans un réceptacle (f) placé derrière la grille (e) au-dessus de la canalisation. Figure pour l’abrégé [Fig. 1]Screening device placed near the protection grid characterized by: - a grid comb (a) is placed on a motorized articulated arm (b), via a pivot connection (h), the arm (b ) is itself held above the pipe (c) by a structure (d) which does not clutter the pipe space, - the comb (a) is placed on the same degree of inclination as the grid protection from debris (e), in such a way as to always have the same distance with the grid (e), - the motorized articulated arm (b) moves the comb (a) from top to bottom and from bottom to top of the debris protection grid (e) according to the following kinematics: = the comb (a) descends, it does not touch the protection grid (e) and leaves sufficient clearance to not carry downward the debris received by the grid (e), = the comb (a) goes up, it comes into contact with the grid (e) to raise the debris into a receptacle (f) placed behind the grid (e) above the pipe.
