Definitions

  • the invention relates to a plant for the production of electrical energy from flowing water using flow-through turbines.
  • the invention further relates to a turbine unit suitable for such a system.
  • the invention has for its object to provide a system for the generation of electrical energy from flowing waters using flow-through turbines, in which structural foundation measures can be largely dispensed with.
  • a turbine unit consisting of one or more flow-through turbines and designed as a closed structural unit with a flow housing which is essentially anchored free floating in the current.
  • Anchoring can take place, for example, by means of ropes which are attached to existing bridge pillars, to pillars specially constructed for this purpose or to buoys, rafts or pontoons anchored in the water.
  • the floating turbine unit can also be suspended from a freely floating buoy in order to determine its depth in the water, or it can be equipped with adjustable depth rudders.
  • the turbine unit can also be anchored directly to the raft or pontoon.
  • All essential regulating and control devices are expediently housed in the unit itself.
  • the cables for current drainage are advantageously routed together with the anchoring cables. Possibly.
  • Required switching, transformer and distribution systems are to be provided in a riverside station.
  • the unit should be provided with cavities in the housing, which may be foamed with a plastic. This measure should expediently be carried out to such an extent that the total weight of the aggregate in the water is only about 0.3 to 1.0 t. In certain circumstances, however, it can also be advantageous to design the buoyancy to be greater than the dead weight of the aggregate, as a result of which the aggregate would float in the event of a depth control malfunction.
  • An appropriate depth for the suspension of the unit is between -3 and -10 m.
  • the flow housing in a preferred embodiment is provided with an inclined rake on the inlet side. see, which has a self-cleaning effect due to its inclination, in that the foreign matter collected is drained up or down by the inclination.
  • the entire system is lifted out of the water, for example onto a pontoon plate, and is possible without difficulty.
  • the floating systems are also suitable for temporary use until, after a corresponding increase in electricity requirements, they can be replaced by permanently installed, larger power plants, if this is structurally possible.

  • FIG. 3 shows a schematic cross section through a turbine unit consisting of a single tubular turbine with counter-rotating vane wheels and generator parts;
  • FIG. 4 shows a front view of the unit according to FIG. 3
  • FIG. 5 shows a schematic, perspective illustration of an unit consisting of two flow-through turbines arranged next to one another.
  • the system for energy generation shown schematically in FIG. 1 consists of a floating turbine unit 1, which is attached by means of ropes 2 to a pillar 3, which is anchored in the bed 4 of a flowing water 5, for example a large river.
  • the pillar 3 is additionally provided with a stiffening rope 6 which is fastened to an anchor 7 in the river bed 4.
  • the depth of the turbine unit 1 in the water 5 is determined by a buoy 9 floating freely on the surface of the water, on which the turbine unit 1 is suspended by means of a rope 10.

  • the turbine unit is provided with tail units 12, which stabilize the axial position of the unit in the water should and can be regulated accordingly. With this type of arrangement, deep rudders are not necessary, since the unit is fixed to buoy 9.
  • FIG. 2 Another type of suspension of the turbine unit is shown in a schematic representation in FIG. 2.
  • the turbine unit 1 hangs by means of ropes 13 on a buoy 14 floating on the surface 8 of the water, which in turn is anchored to the bottom of the water by means of an anchor rope 15. Since the ropes 13 must be made relatively long in this type of arrangement, an additional stabilization of the position is required. In the exemplary embodiment, this is done by means of deep rudders 16 arranged on the side of the unit, which can be controlled by a control device (not shown) in the turbine unit.
  • FIG. 3 shows an enlarged, schematic section of a turbine unit suitable for a system according to FIGS. 1 and 2, which consists of only one single-flow turbine.

Abstract

L'installation pour la production d'energie electrique a partir de cours d'eau comprend des turbines immergees. Les turbines connues de ce type sont ancrees dans le lit de la riviere par des agencements difficiles et couteux. De tels agencements sont superflus si l'ensemble-turbine (1) compose d'une ou de plusieurs turbines immergees et formant une unite fermee, est ancre tout en flottant librement dans l'eau. Des cables (2) sont ancres a des piliers (3), bouees, radeaux ou pontons. Il est aussi possible d'ancrer l'ensemble-turbine directement au radeau (9) ou ponton. Pour augmenter la portance dans l'eau, l'ensemble turbine est pourvu de chambres de flottaison.
