Definitions

  • the invention relates to a hydraulic lifter on a water overflow threshold on a hydraulic structure according to the preamble of claim 1.
  • Wastewater structures have overflow thresholds for flood relief, via which the amount of water in excess of the capacity of the wastewater structure can be drained off directly.
  • the known lifter has the disadvantage that the suction of the water can only begin when the water level in the upper water has risen above the top of the lifter and the air has been swept down by the free overflow and the lifter is completely filled with water . Then the suction of the suction lifter starts suddenly. As soon as air can enter the underpressure in the siphon due to the sinking of the upper water, when the water level has fallen below the opening on the upper water side, its effect is suddenly interrupted again. This can damage the drain pipes. In addition, a balanced withdrawal that adapts to the feed and the discharge is not possible.
  • the invention has for its object to provide a hydraulic lifter with which water can be metered and discharged without sudden insertion and aborting the removal and, in contrast to the free hold-up, can be discharged in a predetermined amount.
  • a larger amount of water can be drained off without extending the overflow threshold and sucked off at a water level below the response point of a conventional lifter, which can then be increased with increasing inflow to the building.
  • Figure 1 is a sewage structure 1 made of concrete, e.g. a relief basin 7 or a channel (only indicated in dash-dotted lines in FIG. 1), with an overflow threshold 3 of length L and height h 1, an inlet 5 into the relief basin 7, an outlet 9 at the bottom of the relief basin 7, an overflow collecting channel 11 with a drain l3 (it could also be a natural body of water) and a diving wall l5, which can also be designed as a sieve and prevents large objects from reaching threshold 3.
  • a drain l3 it could also be a natural body of water
  • a diving wall l5 which can also be designed as a sieve and prevents large objects from reaching threshold 3.
  • overflow threshold 3 are a plurality of covers 20, 20 ′, 20 ′′, 20 façade which are essentially composed of curved plates l7 and adjoining flat plates l9, each forming a lifter, wherein the plates l9 can also have a curvature, so that their lower edges either towards the base of the overflow threshold or directed away from it (indicated in broken lines in FIG. 2).
  • the covers 20, 20 ', 20 “, 20 ′′′ run parallel and at a constant distance from one another, so that the cross sections of the between the covers 20, 20'; 20 ', 20"; 20 “, 20 ′′′; or between the overflow threshold 3 and the cover 20 lying curved spaces 2l, 2l ', 2l” and 2l ′′′ is always constant. It goes without saying that due to different distances between the covers one above the other 20 ... 20 ′′′ the quantity characteristics can be changed. Laterally, the rooms 2l, 2l ', 2l ", 2l are closed by the two walls 23 and 24 of the relief basin 7 or by covers of another design.
  • the curved plates l7 have openings l8 through which the trapped air rises when the In order to avoid the failure of the entire lifter due to clogging by floating material, this can be divided into partial lengths.
  • the rooms 2l ... 2l ′′′ are divided by one or more vertical partition walls 25.
  • the suction power of each level of the jack is the same (if the different heights h2 ... h5 the thigh are neglected).
  • the plates 19 of the outer covers 20 are longer than the inner ones and thus increase the Suction power of the outer lifter sections.
  • the outer covers 20 are made shorter than the inner ones. As a result, the amount of water discharged remains the same or even decreases when the headwater rises.
  • the distance to the outside can also be increased to increase the suction volume, so that larger levers are created. If the distance is reduced, the effect of the jack is reduced accordingly.
  • the suction power of the lifting system according to the invention can thus be designed as a function of or independent of the water level from above and below water.
  • a system independent of the water level finds e.g. Use at a branch if a constant amount of water has to be taken from a pool or flowing water regardless of the upper water level.
  • the edges of the covers on the inlet side are arranged at the same height and can be immersed down to the lowest possible water level in the basin, from which water can still be removed.
  • Both the water level-dependent and the -independent lifting system can be used not only on a straight overflow edge, but also on a cylindrical drain as shown in FIGS. 4/5.
  • FIG. 6 shows a schematic diagram to illustrate the increasing amount of water that can be removed with a water level-dependent lifting system.
  • the dash-dotted line shows the amount discharged per unit of time in the case of a free hold-up without a lifter, the dashed line the amount with a single lifter and the solid line the amount with that in sections split lifter system according to the invention according to the example of FIG. 3.
  • the lifting system can also be used as a regulating device, e.g. constant water withdrawal from a basin or flowing water with constant or changing upper water level.
