    The invention relates to a weir system with gravel lock zumin¬dest having a height-adjustable baffle, for example, consisting of several dam beams made of wood, a laterally adjoining the Tauchwand walling device such as a dam.
    Such weirs are well known in the art and have found many uses for damming flowing water.
    The damming of the waters can be done, for example, to generate electricity from hydropower. In particular, due to rising electricity prices, power generation from water power is becoming increasingly important again.
    In the weir plant of the type mentioned, for example, the underwater level can be about 80 cm lower than the dammed-up upper water level. The baffle wall of such a defense system is usually located mostly under water and rests on the bottom, so the riverbed on. In order to prevent excessive damming of the river at high tide, the baffle wall projects beyond the upper water level only by a predetermined area. This ensures that at high water, the baffle is completely flushed and no unintentional high damming of the water takes place.
    In the weir systems with gravel locks with such a baffle wall, which are known in the state of the art, it is disadvantageous that no continuity for migratory fish both in the upward direction and in the downward direction of the river is made possible.
    In order to allow fishing both uphill and downhill flow, fish ladders and by-pass channels of various kinds at the watercourses are known in the art. However, these have many disadvantages. On the one hand, these require a great deal of space and, on the other hand, in the creation of such fishing reindeer and surrounding nasal pilings, there are often accumulations of heat.
    Furthermore, the fish ladders and bypass channels known in the state of the art can often become impassable for fish by being caught with debris and ground squirts of any kind, so that high maintenance costs are incurred to remove the congestion in order to maintain the constant passability. Moreover, it is disadvantageous in the known fish ladders and bypass channels that fish-eating birds, such as, for example, cormorants, have easy access to the fish migrating downstream and upstream. Thus, by the fish ladders and by-pass channels known in the art, the fish often can not meet its natural cover requirement.
    It is an object of the present invention to provide a weir with a gravel lock which ensures safe and unrestricted migration of migratory fish in both the upstream and downstream direction of the river, which is inexpensive and easy to produce and has little or no maintenance cost at the same time having a long service life.
    To achieve this object, the invention proposes that the dipping wall has perforations which are arranged below the water level and form a passage for migratory fish.
    By means of perforations formed in the baffle, migratory fish can swim without floating to the surface of the water, migrate the baffles both in the downstream direction and in the upstream direction and thus reach their spawning grounds and back again as far as possible without risk. Clotting with debris and squirts of any kind is largely precluded in such a baffle according to the invention, since the holes are located below the level of the water and collection, which leads to clotting, usually occurs at the water surface.
    In addition, such a baffle wall is inexpensive and easy to drive and wpi st · pinp hnhp T, phpnsiianpr on.
    By means of such a baffle according to the invention, the cover requirement of the fish has been completely fulfilled in a safe manner, both on its migration upstream in the direction of its spawning areas and downstream.
    In particular, it may be particularly preferred that the holes are formed in the direction of flow of the watercourse.
    Alternatively, it may further be particularly preferred that the perforations are formed obliquely to the flow direction of the watercourse.
    In addition, it may be particularly preferred that the Lochun¬gen have different diameters.
    It may also be particularly preferred that the Lochun¬gen circular, oval or elliptical are formed.
    Alternatively, it can be particularly preferably provided that Lochun¬gen polygonal, in particular triangular, square or hexagonal are formed.
    The perforations forming a passage can be formed in the most varied forms both in the flow direction and at an angle to the flow direction of the flowing water. In addition, through the various diameters and also in combination with various round shapes such as, for example, a circular, oval or elliptical shape or also a polygonal shape, in particular a triangular, quadrangular or hexagonal shape, different types of fish can pass through the baffle wall become. In this case, the respective shape and the respective diameter represent an optimum passage shape for the respective migratory fish. Thus, for example, one fish species can migrate through circular perforations formed parallel to the flow direction of the waterway, and another fish species different therefrom can migrate through elliptical and oblique to the flow direction of the watercourse.
    In this case, in order to permit injury-free migration of the fish through the respective hole shape, material recesses may be formed on the side edge edges of the perforation at the respective edge regions of the perforations, so that the respective fish can correspondingly swim through the perforation in its streamlined form.
    In addition, it can be particularly preferably provided that before or at the perforations means for limiting the flow-through speed of the water flowing through the perforations are arranged.
    It can be particularly preferably provided that the Lochun¬gen are extended tube-like, the extensions have to limit the flow rate of the water flowing through the perforations a deviating from the flow direction, in particular a transverse to the flow direction opening, angling.
    Through such tubular extensions, which may also be formed by the holes in the direction of flow projecting pipe sections, it is possible to adjust the so-called Leit¬ flow, so the flow velocity of the perforations durch¬ flowing water. Migratory fish develop positive rheotactic behavior at a certain flow rate of the water, that is to say they orient themselves to the source of irritation of the flowing water. In this case, the flow-through speed of the flow water must be smaller than the respective affordable speed of the hole durch¬wandernden fish. The passage time of the fish should be less than the maximum time that the fish can maintain the speed needed to travel through the hole.
    By means of the angling of the tubular extension of the perforation, the throughflow velocity of the water flowing through can be reduced or targeted by the angle of the angling, in particular.
    It can also be particularly preferably provided that, as means for limiting the flow velocity, the perforation is covered in each case by a plate which covers the respective perforation and is spaced from the respective perforation, the plate surface being arranged upstream of the respective perforation in the flow direction.
    In this case, it may be particularly preferred that the platform has a rectangular or square shape and is connected to the immersion wall at three of the four side edge edges of the plate by means of a web, wherein the distance between the immersion wall and the plate is formed by the height of the webs.
    Such an arrangement of a plate on the upstream side in the direction of flow in front of the respective perforation gives a particularly effective possibility, which is easily adjustable by the size of the plate, of limiting or preselecting a predetermined flow rate of the flow water through the perforation. The distance of the plate from the baffle is determined by the height of the arranged at the side edge edges of the plate and the plate with the dip wall connecting webs. The plate can be dimensioned in size such that it covers the Durchgangs¬ perforation for migratory fish only slightly or in a wider range. Thus, adjustment of the flow velocity according to predetermined wishes is made possible both by the covering area and by the distance to the baffle wall formed by the webs.
    The water flowing through first has to flow around the plate in order to flow through the perforation, in order then to continue the original flow direction again after flowing through the perforation. The flow rate of the water is already significantly reduced upon impact with the plate and can be adjusted to the predetermined maximum flow rate for the particular migrating fish, both by the size of the plate and by the height of the webs connecting the plate to the baffle.
    Further, it may be particularly preferred that the plate is rigid.
    Alternatively, it may be particularly preferred that the plate is flexible.
    Depending on the intended use, that is depending on the type of migratory fish to be considered, both a rigid and a flexible plate can be used. Especially with larger fish, this makes it possible to push away the flexibly formed plate, which is formed, for example, by a rubber plate, when passing through, in order to create the required space.
    It may also be particularly preferred that the plate is hinged to one of the webs and pivotable against the flow direction of the water.
    As a result, pivoting of the plate as it passes through the fish is made possible, in particular also in the case of the arrangement of a rigid plate. The plate may, for example, be hinged to one of the webs by means of a hinge disposed on one of the webs, and in the non-use position, that is to say in the position in which the perforation is not floated by a fish, approximately parallel to the baffle and in the position of use, that is in the situation where the plate is touched and pushed away by the floating fish, it is in a position at an acute angle to the baffle wall.
    Finally, it may be particularly preferred that the dip wall has a recess or bulge in its base-facing area.
    By arranging such a recess or bulge on the area of the submersible wall facing the base, substances located on the bottom of the flowing water can pass through the immersion wall, without causing accumulation in front of the submersible wall.
    An embodiment of the invention is illustrated in the figures and described in more detail below.
    It shows:
    1 shows a gravel lock according to the invention of a weir system seen from the front;
    Figure 2 shows a detail of a baffle with indicated perforation and arranged in front of the perforation flap in the non-use position of the flap in plan view;
    FIG. 3 likewise with the flap open;
    Figure 4 shows another embodiment of the baffle of Figure 2 with flexible flap in plan view;
    Figure 5 shows the embodiment of Figure 2 in the flow direction seen from the front;
    Figure 6 shows another embodiment with tubular extension of the hole in plan view.
    FIG. 1 shows the gravel lock of a diving wall 1. Such weirs have at least one height-adjustable immersion wall 1 and a stowage device 3, which adjoins the diving wall 1 laterally, such as a dam wall. The dip wall 1 consists of several superposed dam beams 2, which are formed in the embodiment of wood.
    According to the invention, the baffle 1 perforations 4, which are arranged below the water level and form a passage for migratory fish.
    As can be seen in particular from FIG. 1, many different shapes and different diameter perforations 4 are formed on a submersible wall 1. This allows many different species of fish to travel through the dip wall 1 in both the upstream and downstream direction of the watercourse. The perforations 4 are formed parallel to the flow direction of the flowing water and / or obliquely to the flow direction of the watercourse. In addition, the holes 4 have different diameters. In order to enable as many species of fish as possible to pass through, the perforations may have different shapes, such as, for example, a circular, an oval, or an elliptical shape.
    Alternatively, and not shown in the figures, the Lochun¬gen 4 may also have a polygonal shape such as a triangular, quadrangular or hexagonal shape.
    Thus, both through the different diameters and through the different shapes of the perforations 4, walking through many different types of fish through the baffle 1 is safe and easy. The fact that the holes 4 are all located below the surface of the water also significantly reduces the risk of access by birds, such as a cormorant.
    In order to adapt the flow velocity of the flowing water in accordance with the speed afforded by the respective fish, means for limiting the flow velocity of the water flowing through the perforations 4 are arranged in front of or at the perforations 4.
    As can be seen in particular from FIG. 6, the perforations 4 for regulating the flow-through velocity of the water can be extended like a tube (at 5). In this case, the extension 5 for limiting the flow velocity of the water flowing through the perforations 4 on an angle 6 deviating from the Durchströmungs¬ direction. In the exemplary embodiment, the bend 6 is designed to open toward the direction of flow. By the angle of the bend 6, the flow rate of the water flowing through the perforations 4 can be regulated as desired, so that the Durchström¬ speed is lower than the respective affordable Geschwin¬digkeit of the perforation 4 with extension 5 by walking fish.
    As can be seen from FIGS. 2 to 5, the perforation 4 can be covered in each case by a plate 7 which covers the respective perforation 4 and is spaced from the respective perforation 4 as a means for limiting the flow velocity. In this case, the plate 7 is arranged on the upstream side in the flow direction in front of the respective perforation 4. The plates 7 shown in the embodiment have rectangular shapes. Alternatively, a shape deviating from the rectangular shape, such as a square shape, is also possible.
    The plate 7 is connected at three of its four side edge edges by means of a web 9 with the baffle 1. The height of the web 9 in each case determines the distance between the baffle wall 1 and the plate 7. In the embodiment shown in FIGS. 2, 3 and 5, the plate 7 is rigid. The plate 7 shown in Figure 4 is flexible and made of rubber.
    As can be seen in particular from Figures 2 to 4, the plate 7 is hinged to one of the webs 9 (at 8) and pivotable against the direction of flow of the water. The plate 7 can thus be pivoted by the fish against the direction of flow of the water before swimming through the perforation 4 in order to increase or facilitate the passage for the fish. In this case, in particular, the flexible plate 7 can also be fastened to the web 9 without a joint and be pushed away from the fish when swimming through in order to enable or facilitate through-swimming.
    As can be seen from FIG. 1, the baffle wall 1 has a recess or bulge 10 in its region facing the base. As a result, the removal of material located on the bottom of the watercourse is made possible, so that an explanation and, if appropriate, blockage of the perforations 4 are prevented as far as possible.
    The invention is not limited to the embodiments, but in the context of the disclosure often variable.
    All individual and combination features disclosed in the description and / or drawing are considered to be essential to the invention.
