Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • EP-A-0 346 311 Such a generic device is shown in EP-A-0 346 311.
  • the movable cover is fastened to the movable rake bars, as a result of which the cover can jam on the channel base, in particular when the movable rake bars move downward, or can be blocked by solids located on the channel base .
  • the function of the double grating rake in the lower area in corners and between sand and / or solids building up between fixed and movable rake bars can even be blocked and even blocked.
  • the rake bars in the lower area are exposed to very high wear, which means that the requirement for a constant gap width can no longer be met.
  • the main advantage of the inventive design of the generic device can be seen in particular in that a malfunction or a blocking of the double grating can be avoided in a simple manner and self-cleaning is also made possible by the mobility and flying mounting 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 rake 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 by means of a cross bar 6, which is above the channel base 5 is arranged on the underwater side, that is, behind the rake bars 2, 3, so that the fixed rake bars 2 are cantilevers in the lower region, fastened in the frame 4.
  • 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. This cleans the critical area before double grating 1 and prevents sand sedimentation.
