Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Such a device is known from EP 0221 991 B1.
  • the lower end regions of the fixed rake bars facing the channel bottom have a material thickness which corresponds essentially to the distance between the movable rake bars, so that the slots between the fixed rake bars are essentially closed when the movable rake bars are in their lowermost positions .
  • the rake bars are exposed to very high wear in the lower area, which means that the requirement for a constant gap width can no longer be met.
  • the main advantage of the design of the generic device according to the invention can be seen in particular in the fact that that a malfunction or a blocking of the double grating rake can be avoided in a simple manner and self-cleaning is also made possible by the mobility of the flap.
  • the drawing shows a section of a double screen 1, namely the lower part essentially in a side view.
  • the double screen 1 with its fixed rake bars 2 and movable rake bars 3 is arranged in an indicated frame 4, which stands on the channel base 5 of a channel, not shown.
  • the fixed rake bars 2 are fastened in the frame 4 by means of a crossbeam 6, which is arranged above the channel bottom 5 on the underwater side, i.e. behind the rake bars 2, 3, so that the fixed rake bars 2 are cantilevers in the lower region.
  • This opening 8 between the channel base 5 and the fixed rake bars 2 is sealed by means of a movable flap 9 so that the water with the solids therein does not flow unhindered and no sand and / or solids which block the double grating screen 1 can build up here.
  • the movable flap 9 is overhung in such a way that it rests with its upper edge 10 on the bottom step of the fixed rake bars 2 and rests with its lower edge 11 on the channel base 5 and by means of one or more on the one hand on the rear wall of the flap 9 and on the other hand on the channel bottom 5 attached traction elements 12 is held with load.
  • the lower edge 11 of the movable flap 9 can also be brought in the direction of position 15 by means of an opening lever 14. As a result, the critical area before the double grating rake 1 is cleaned and sand sedimentation is prevented.
