    专利说明:

    The invention relates to an arrangement of flowing waters in the region of a transverse structure and / or waterworks, in particular fish lift, for transporting aquatic animals, especially fish, with a substantially vertical shaft, in which a transport unit between the area of the underwater, in particular the underwater mirror, and the region of the upper water, in particular the upper water level, is movable, wherein the transport unit is in communication with at least one buoyancy agent.
    Under transverse structures are understood to mean natural and artificially introduced into a body of water, running across a waters bed structures that the natural
    Influencing the flow conditions and thus also the bottom and shore structure of the water body. Examples of transverse structures are sills, ground sleepers, support sleepers, bottom ramps, bottom steps, bottom slips, crashes, weirs or dams.
    The height difference of the water levels between the upper water and the underwater makes it impossible to fish, the obstacle, e.g. jumping, to overcome.
    Fish passages in the form of fish passes, which enable fish and other aquatic animals to encounter obstacles, e.g. It is well known to overcome weirs or natural saline steps. In order to reduce the distance of the water levels from upstream to underwater gradually, it is known in fish migration aids to provide several pools with different levels of water. At many locations with hydroelectric power plants, however, the fall height for water is so great that a very large number of basins is necessary if the current requirements for the height of fall from pool to pool are observed. Along with the typical requirements for pool size (e.g., pool length = triple fish length with a typical governing fish length of about 1 m), very large fish migration aids result. Their construction is so expensive even with open construction field that investments in renewable energy through hydropower are often not worthwhile, even on existing dams.
    One embodiment of a fish migration aid with which a large gradient can be overcome with a small footprint is a fish lift.
    Fish lifts are known in which fish are lifted in the area of the underwater in a tub from the water. In the area of the upper water, the tub is tilted, so that the water in the tub is led together with the fish in the upper water. A disadvantage of fish lifts is that they are structurally complex and consume a lot of energy, especially since the full weight of the water-filled tub in which the fish are collected, must be raised. In addition, the attraction of the fish, so they swim in the underwater in the tub, and in particular the tipping of the tub in the area of the upper water, not gentle for fish. Another disadvantage is that fish can only swim in the fish lift when the tub is located in the shaft at the bottom and that fish can only be transported from the underwater into the upper water but not from the upper water in the underwater.
    In addition, fish lifts are known with a substantially vertical shaft in which the water level between the area of the upper water and the area of the underwater is variable. The fish are usually transported in a basket acting as a reuse in the shaft, with the disadvantage that fish can swim in one direction only in the basket or out of the basket. Fish can be transported either only from the underwater into the upper water or only from the upper water into the underwater.
    Furthermore, fish lifts are known in which the fish can be transported in a basket in the shaft of the underwater in the upper water or from the upper water in the underwater. The shaft has open and closable openings in the area of the upper and lower water, through which the fish in the
    Shaft into or out of the shaft. The basket also has openings in the basket wall. A disadvantage is (as in a trap) that the openings in the basket wall in the respective position of the basket in the region of the lower and upper water must correspond with the openings of the shaft, otherwise the fish can not pass. To ensure this, guides arranged along the shaft, e.g. Rails, known in which the basket is guided. However, such guides represent a technical effort and can encourage confusion. There is also the risk that a guided in rails basket in a rail canted and stuck in the shaft.
    The invention is based on the object to provide an arrangement of the type mentioned, in which disturbing influences during transport of the fish, such as. Tilting of the transport unit or at least partially closed inlet or outlet openings, be avoided by the underwater into the upper water or from the upper water into the underwater.
    This object is achieved according to the invention with an arrangement having the features of claim 1.
    Preferred and advantageous embodiments of the invention are subject of the dependent claims.
    According to the invention, it is provided that the transport unit can be moved without guidance in the shaft and that the transport unit is designed without a wall, in particular as a disk. Due to the fact that the transport unit has no walls at the side, there is no risk that the openings in the shaft can be at least partially closed by such a wall. The fish can thus always freely into the shaft or out of the shaft to swim when the corresponding opening in the shaft is open. Thus, the arrangement of the openings of the shaft is freely selectable, i. The fish can swim in or out of the shaft
    Shaft out, wherever an opening in the shaft is located. Furthermore, the risk that the transport unit canted with a component excluded, since the transport unit is freely movable in the shaft without guide device.
    With the arrangement according to the invention it is achieved that fish can be transported from the underwater into the upper water or from the upper water into the underwater without disturbing influences.
    In a particularly preferred embodiment, the shaft has a substantially circular cross-section, whereby the risk that the transport unit canted due to their shape in the shaft, is practically impossible. However, other embodiments in which the shaft has a differently shaped, for example rectangular, cross-section are also conceivable.
    Furthermore, the transport unit is preferably arranged rotatable about a central axis of the shaft in the shaft.
    The size and shape of the transport unit is preferably adapted to the size and shape of the cross-sectional area formed by the inner wall of the shaft, such that the outer circumference of the transport unit substantially corresponds to the inner circumference of the shaft. This prevents the aquatic animals being transported from passing the transport unit.
    In a preferred embodiment, the transport unit consists essentially of a water-permeable pane, in particular of a disc-shaped perforated plate, wherein a commercial, adapted to the desired shape Niro perforated plate can be used. The transport unit may for example have slot-shaped holes.
    Preferably, the transport unit is in the installed position in a substantially horizontal plane, in particular so that this plane is arranged transversely, substantially orthogonally, to the central axis of the shaft. By this embodiment, the transport unit is particularly low along the central axis of the shaft up and down movable. Embodiments in which the center axis of the shaft is inclined, and / or in which the transport unit lies in a plane which is not arranged orthogonal to the central axis, are also conceivable.
    In a preferred embodiment, means are provided for raising and lowering the water level in the shaft between the area of the underwater, in particular the underwater level, and the area of the upper water, in particular the upper water level. For this purpose, any forms of inlets or outlets in the shaft, designed for example as a pipe system, serve, which can be controlled or operated manually or automatically.
    It is particularly preferred that the wall of the shaft associated with the underwater has a first opening and means for opening and closing this opening, in particular a first slide, and that the wall of the shaft assigned to the upper water has a second opening and means for opening and closing the latter Opening, in particular a second slider having.
    A particularly preferred embodiment of the arrangement is connected to an additional device for moving the transport unit along the shaft, in particular a pulling or pushing device. Thus, the system can work trouble-free even with fluctuating upper water levels, since the transport unit can stand or hang at the desired height.
    By combining with a water-permeable pane, in particular a perforated plate, can move up and down the
    Transport unit used a winch with relatively low power rating. This offers a great advantage over known fish lifts with winches, in contrast, have a transport unit in which not only fish, but also the water in which the fish are located, must be transported in a correspondingly sized transport basket. As a result, very powerful winches have to be used which are able to move the combined weight of aquatic animals, water and transport basket up and down.
    Preferably, the device for moving the transport unit along the shaft on a arranged on the transport unit rope, in particular a steel cable, and a cable winch connected thereto.
    In a preferred embodiment, two or more chains or ropes, in particular steel cables, are arranged radially symmetrically on the transport unit, which in turn are connected to the cable of the device for moving the transport unit, for example by means of a metal hook. The winch of the device for moving the transport device can be arranged in such an embodiment on a support device, for example a steel beam, in the upper region of the shaft, in particular centrally above the shaft.
    In a further preferred embodiment, measuring means, in particular sensors, are provided in order to record status data of the water body, in particular the water level of the underwater and / or the upper water and / or the water level in the shaft. Other suitable measuring means, except sensors, can be used for this purpose.
    To be considered particularly favorable embodiment, in which means for raising and lowering the water level in the shaft and / or the device for moving the
    Transport unit along the shaft and / or means for opening and closing the first and / or second opening by the means for detecting the state data of the flowing water are automatically controlled.
    In the context of the invention, the buoyancy means may be at least one float, for example a hollow body, preferably an inflatable float. In the case of an inflatable float it can be provided that it is controllably filled with air by a compressor and that the air can be controllably released from the float.
    The at least one buoyancy means can be arranged in the shaft above or below the transport unit. It can also be provided below and above the transport unit at least one buoyancy means. Preferably, the buoyancy agent is annular.
    In a preferred embodiment it is provided that in the shaft above the transport unit a stop means for the transport unit is arranged, wherein the stop means is preferably provided in the region of the second opening of the upper water associated wall of the shaft. The stop means may consist of at least one protruding into the shaft projection. The stop means forms a stopper system for the transport unit, which limits an upward movement of the transport unit. This ensures that the transport unit does not move beyond the second opening of the shaft even if the water level continues to rise in the shaft, but is always correctly positioned in the region of the second opening for trouble-free entry or exit of aquatic animals.
    In the context of the invention, a holding device for the transport device may be provided, so that the transport unit can be held in the desired position. For example, the transport unit can be kept in the shaft in the region of the second opening even when the water level is falling. The holding device may comprise controllable magnets which cooperate with the transport unit or with a metal part arranged on the buoyancy means.
    Further details, features and advantages of the invention will become apparent from the following description with reference to the accompanying drawings, in which preferred embodiments are shown. It shows:
    Fig. 1 is a sectional view of a first embodiment of a fish lift according to the invention and
    Fig. 2 is a sectional view of a second embodiment of a fish lift according to the invention.
    1 and 2 show a fish lift according to the invention, in which aquatic animals are transported by means of a water-permeable transport unit 1 in a vertical shaft 2 between the region of the underwater 3 and the region of the upper water 4.
    In these embodiments, the transport unit 1 is a circular perforated plate whose outer diameter is approximately as large as the inner diameter of the likewise circular shaft 2, so that only a gap 5 which is as narrow as possible can arise between transport unit 1 and shaft 2. If the transport unit 1 is moved along the shaft 2, water can flow through the holes of the transport unit 1 and past the transport unit 1 through the gap 5, wherein the size of the holes and the width of the gap 5, the unwanted passing of aquatic animals from a certain Prevent size.
    An underwater 3 associated wall 6 of the shaft 2 has in the region of the underwater sole an entry opening 7 in the shaft 2 and an indicated means Sl, for example, a gate valve, for opening and closing the
    Entry opening 7 on. A wall 8 of the shaft 2 assigned to the upper water 4 has in the region of the upper water level an outlet opening 9 from the shaft 2 and an indicated means S2, for example a gate valve, for opening and closing the outlet opening 9.
    In order to move the transport unit 1 along the shaft 2 depending on the water level in the shaft 2, a buoyancy means 18 in the form of an annular, inflatable float is provided above the transport unit 1. In the context of the invention, the buoyancy means 18 is preferably arranged at a certain distance above the transport unit 1, so that the buoyancy means 18 is arranged in the catch phase in the region of the underwater 3 above the water level in the shaft 2.
    In order to be able to move the transport unit 1 along the shaft 2 independently of water levels, a device 10 is provided. In this case, a plurality of ropes 17 along the edge 11 are attached to the transport unit 1, which in turn are connected via a hook 12 with a long rope 13. The long rope 13 is connected to a winch 14, over which it can be wound up or unwound, and which is arranged in the illustrated embodiment on a beam support 15 centrally above the shaft 2. By winding the long rope 13, the transport unit 1 the shaft 2 is moved upward. The unwinding of the rope 13 causes a sinking of the transport unit 1 along the shaft 2 due to its own weight.
    There are no guide rails necessary, whereby the running as a disc transport unit 1 can rotate arbitrarily about the central axis of the shaft 2 and wherein the transport unit 1 is substantially parallel to the water levels of the lower 3 and upper water 4, ie horizontally. The circular shape of the transport unit 1 and the narrow gap 5 between the edge 11 of the transport unit 1 and the shaft 2 support the effect that the
    Transport unit 1 does not tilt when sinking in the shaft 2 and does not get stuck in the shaft 2.
    By opening and closing the openings 7, 9 and not shown means for raising and lowering the water level in the shaft 2, for example in the form of piping systems, the water level in the shaft 2 can be controlled lifted or lowered. Thus, the water level in the shaft 2, for example, rises to the level of the upper water level 4 when the opening 7 is closed and the opening 9 is opened, or drops to the level of the underwater mirror 3, when the opening 7 is opened and the opening 9 is closed.
    The means SI, S2 for opening and closing the openings 7, 9 and the device 10 for moving the transport unit 1 along the shaft 2 are automatically controlled in the embodiment shown, depending on the default and environmental data, such as water levels or flow velocities, by not shown sensors are determined.
    In order to prevent the transport unit 1 from rising above the lower edge of the second opening 9 by the buoyancy means 18 when the water level in the shaft 2 rises, stop means 19 are provided in the region of the lower edge of the second opening 9.
    The operation of an arrangement according to the invention as a fish lift is shown by way of example for the transport of aquatic animals from the underwater 3 into the upper water 4:
    In the capture phase, the transport unit 1 is located in the shaft 2 below the level of the water level of the underwater 3.
    In the position shown, the disc-shaped transport unit 1 is aligned with a small ramp 16 in the region of the bottom of the underwater 3, so that aquatic animals are not among the
    Transport unit 1 can get. The water level in the shaft 2 corresponds to the water level of the underwater 3, wherein the opening 7 is completely open and the opening 9 is open in the upper water 4 only to a small extent. The flowing through the outlet opening 9 in the shaft 2 and flowing out of the shaft 2 through the manhole 7 in the underwater 3 water generates a lock flow, are lured by the aquatic animals in the interior of the shaft 2. Since the transport unit 1 is not designed as a basket, but as a flat disc, ie without side edge, the transport unit 1 can be arbitrarily rotated about the central axis of the shaft 2, without thereby preventing aquatic animals from underwater 3 through the manhole 7 in the Schacht 2 can get into it.
    After a fishing time of, for example, 20 minutes, the manhole 7 in the underwater 3 is closed. Not shown means for raising the water level in the shaft 2 and / or by opening the outlet opening 9 of the water level in the shaft 2 is raised to the level of the water level in the upper water 4. The transport unit 1 is moved by the buoyancy means 18 and / or by winding the rope 13 along the shaft 2 upwards, in the direction of the upper water 4. The aquatic animals located in the shaft 2 are raised by the transport unit 1 from the region of the underwater 3 in the region of the upper water 4, where they can leave the shaft 2 in the upper water 4 through the already open or yet to be opened opening 9 in the upper water 4 ,
    After completion of the aquatic animals, or after a certain period of time, the opening 9 is closed by a slide S2, whereby the flow of water is prevented in the shaft 2. The manhole 7 is opened and the water level in the shaft 2 drops again to the level of the water level of the underwater 3 from. At the same time or before, the rope 13 (if present) is unwound, whereupon the transport unit 1 the shaft 2 down along, in the direction of underwater 3, decreases. The opening 9 in the region of the upper water 4 is again partially opened, so that water from the upper water 4 can flow into the shaft 2 and generates a lock or guide flow in the region of the lower water 3.
    The transport unit 1 is round, for example, with a diameter of about 2.50 m, designed so that the size-determining species grayling with a length of about 50 cm, the fish lift can use without problems.
    For controlling aquatic animals, the opening 9 is closed in the region of the upper water 4 when the transport unit 1 is in the area of the upper water 4. The transport unit 1 can be lifted by the winch 14 as far along the shaft 2 that the aquatic animals can be caught with crayfish. For maintenance, the transport unit 1 can also be pulled completely out of the water or out of the shaft 2.
    An embodiment of the invention can be summarized as follows:
    An arrangement of flowing waters in the region of a transverse structure and / or waterworks, in particular a fish lift, for transporting aquatic animals, in particular fish, has a substantially vertical shaft 2, in which a transport unit 1 between the region of the underwater 3, in particular the Underwater mirror, and the area of the upper water 4, in particular the upper water level, is movable. The transport unit 1 is connected to at least one buoyancy means 18 in connection. The transport unit 1 is guide-free in the shaft 2 movable and is wall-free, especially as a disc executed.
