Definitions

  • the invention relates to a weir with a turbine system arranged therein, wherein the turbine system is arranged as a unit in a recess of the weir and the weir is equipped with a fishway.
  • Devices for power generation in jammed water courses are known in a variety.
  • the facilities are an intervention in the aquatic ecosystem, as dams or weirs are an insurmountable obstacle to migratory fish.
  • the construction of a turbine house for receiving and maintaining the turbine means a further effort and intervention both in the ecosystem of the waters and in the landscape.
  • DE 195 10 347 C1 which shows a weir according to the preamble of claim 1
  • a climbing aid for aquatic organisms is described at dams in streams, in which the fish can overcome the height of the dam via a spiral staircase.
  • the disadvantage here is the considerable construction effort, in addition to the relatively small weir system, a much larger channel system is required.
  • DE 100 17 598 C2 describes a bypass which directs the fish past the turbine. Again, there is the disadvantage of a considerable construction effort. Since the bypass is created below the turbine plant, the landscape protection is indeed However, the underground construction makes the overall production costs more expensive and makes maintenance more difficult.
  • the present invention is based on the object to provide a device for generating electricity at a weir in a watercourse, this device should overcome the above-mentioned disadvantages in the installation of fishways. Furthermore, the present invention is to dispense with a nacelle and the associated expenses and interventions in the ecosystem.
  • the solution of the problem provides, starting from DE 195 10 347 C1, that the turbine system has a smaller mounting cross section than a corresponding receiving cross section of the recess and that a difference of the cross sections is formed as a fish way.
  • the advantage here is that the structural complexity is kept low when setting up the turbine system.
  • the turbine system is arranged as a unit in only one recess of the weir. Thus, no damage to the landscape structures, such as a nacelle or a separate fishway are necessary because the latter is integrated with the recess.
  • the turbine system is provided with a closed and flowed through diffuser.
  • the advantage here is that the energy of the flowing water can be used optimally and the downstream outlet of the turbine system can be located away from the weir. Outcrops in the area of the weir are thereby reduced.
  • the recess is arranged in the region between the water surface and the bottom of the water. The advantage here is that even aquatic animals living close to the ground can overcome the obstacle formed by the weir. In order to avoid spoilage, stabilization of the ground must be ensured in the basement area.
  • a downstream outlet to the fishway is arranged transversely to the flow direction of the water body. The advantage here is that the output is located in an area where the flow is calm.
  • a deflecting device for fish is provided in the inflow area of the weir. This prevents the aquatic animals get sucked into the turbine system and are directed by this deflector directly into the fishway.
  • an inflow-side access to the fishway is arranged in the outflow region of the deflection device. The advantage here is that the fish are directed by the deflector directly to the entrance of the fish way. If the deflection device is designed as a narrow rake, the fish are guided along the rake to the fish path and can thus overcome the weir.
  • the flow path of the water along the fishway is formed meandering.
  • the advantage here is that the flow in the fish way braked and the flow is reduced. If the fishway is dimensioned sufficiently large and areas of low flow are formed in the individual loops of the meander, this formation offers the fish the least resistance in overcoming the obstacle.
  • the fishway is designed as a rough ramp. Also versions as a fish ladder or fish ladder are possible. The advantage here is that the flow is naturally slowed down and the aquatic animals a familiar environment to overcome the existing obstacle is offered.
  • FIG. 1 is a schematic plan view of a river power plant and Fig. 2 is a vertical section through a river power plant.
  • FIG. 1 shows a plan view of a weir 2 lying between the two shores of a river.
  • a recess 3 is provided, in which a device for power generation, in particular a turbine 4, is arranged.
  • a device for power generation in particular a turbine 4
  • This has on the upstream side of a rake 5, which also serves as a deflection device for fish.
  • a diffuser 6 is shown in extension to the turbine 4, which significantly improves their efficiency.
  • the recess 3 is wider than the inlet region of the device for generating electricity. Left and / or right thereof, in the illustrated embodiment on both sides, a free space is recognizable, are connected to the fishways 7, 8.
  • the deflecting action of the rake 5 is designed so that the fish are guided with the flow to the upstream access of the fishways 7, 8.
  • fishways 7, 8 all known fish ladders or fish ladders can be used.
  • the illustration shows the position of the downstream exits 9 of the fishways 7, 8, which are applied perpendicular to the flow direction of the river.
  • a meander 10 on the left and on the right of the power generation device limits the flow through the recess 3.
  • a lifting device 1 1 can lift the entire device for power generation from the weir.
  • the lifting device 1 1 consists for this purpose, for example, two rails, between which the turbine plant is performed.
  • the lifting is done for example by a crane or similar device.
  • the device for power generation is designed in the best case as a dive turbine.
  • the dive turbine forms a compact unit of turbine 4, generator and as needed control and power electronics.
  • a powerhouse as is customary in turbine plants, saved.
  • a cable for forwarding the electrical energy generated is connected directly to the diving turbine.
  • the dive turbine also mounted on a lifting device 1 1, so this has the advantage that the turbine 4 is easily accessible for maintenance purposes.

Abstract

La présente invention concerne un barrage dans lequel se trouve une installation de turbine. Ladite installation de turbine est placée sous forme d'unité dans un logement du barrage, le barrage est équipé d'une passe à poissons et l'installation de turbine présente une section transversale de montage inférieure à une section transversale de réception correspondante du logement, la différence de section transversale constituant la passe à poissons.
