Abstract (en)
[origin: EP0484724A2] In order to provide a device for collecting and delivering solid particles which are carried along by flowing water in drains or the like, in the form of a double-grid screen (1) arranged in a frame (4) and having fixed and movable screen bars (2, 3) whose surfaces facing the direction of flow are stepped, the movable screen bars (3) being connected to one another in order to form at least one unit which can be actuated by means of a drive mechanism which gives the movable screen bars (3) a closed motion path essentially in the plane of the screen bars (3), its upward motion component being slightly greater than the step height of the fixed screen bars (2), and the lower end areas, facing the drain bottom (5), of the fixed screen bars (2) having a continuous cover arranged transversely to the flow direction in front of these screen bars (2), which device not only guarantees that solid particles cannot pass the double-grid screen (1) unimpeded in the bottom area and that obstruction or blockage of the double-grid screen (1) by sand and/or solid particles building up in the bottom area can be avoided, but that cleaning in this area is unnecessary or is made possible in a simple manner, the continuous cover is designed as a movable flap. <IMAGE>
