Definitions

  • the invention relates to a device for energy conversion, in particular a device for converting potential energy present in a fluid and kinetic energy (due to flows present in the fluid) into electrical energy.
  • the invention has for its object to provide a device that allows efficient energy conversion.
  • the device for energy conversion has a rotationally symmetrical liquid reservoir with an outlet, at least one turbomachine arranged in the outlet, which can be driven by a liquid flowing through the outlet, at least one generator coupled to the turbomachine for converting the energy transferred by the liquid to the turbomachine electrical energy and a feed pump for transporting the liquid discharged from the outlet to the liquid reservoir.
  • the turbomachine As the liquid in the liquid reservoir flows through the outlet, it drives a turbomachine coupled to a generator for generating electrical energy.
  • the drive of the turbomachine can be done both by a flow of liquid due to the force acting on these gravitational force, as well as in the liquid existing currents and / or vortices.
  • the turbomachine can also be driven (ie, at least in part) by fluid swirls that form spirally around the axis of rotation of the liquid reservoir. These fluid swirls can be generated, for example, by (external) introduction of spiral-shaped liquid flows and / or by fluid flows that form independently within the fluid (for example due to the Coriolis force).
  • the turbomachine After the liquid has passed the turbomachine, it can be transported back to the liquid reservoir with the aid of a delivery pump. In this way an uninterrupted energy conversion is possible.
  • the turbomachine is designed as a rotor or as a turbine, in particular as a water turbine.
  • the device further comprises a control unit, which is electrically connected to the generator and the feed pump, and the electrical energy generated by the generator, the feed pump feeds. In this way, the electrical energy generated by the generator can be used to drive the feed pump.
  • the feed pump can also be supplied by other energy suppliers with electrical energy.
  • renewable energy sources wind energy, solar energy, Certainly can be used for this purpose.
  • the device further comprises a derivative for the transmission of electrical energy to an external Network up.
  • the electrical energy generated by the generator can be removed from the device and fed to other electrical loads or fed into the public power grid.
  • the liquid reservoir is either funnel-shaped or annular. Such geometric shapes facilitate the formation of helical flows within the fluid reservoir.
  • the device further comprises a feed opening in the edge region of the liquid reservoir, through which the liquid conveyed by the feed pump is transported into the liquid reservoir. In this way, the formation of spiral vortices within the liquid reservoir can be particularly facilitated.
  • a plurality of turbomachines is present. These can be positioned in particular in an annular outlet. In this way, a further increase of the converted electrical energy can be achieved.
  • either the outlet on the axis of rotation of the liquid reservoir or the feed pump is formed on the axis of rotation of the liquid reservoir.
  • Fig. 1 shows a first embodiment of a device for energy conversion.
  • the device 1 has a rotationally symmetrical, funnel-shaped liquid reservoir 2.
  • the vertically lower end of the liquid reservoir 2 is formed as an outlet 3. Through this outlet 3 liquid, which is located in the liquid reservoir 2, flow out.
  • outlet 3 designed as a rotor 4 turbomachine is arranged. Both the outlet 3 and the rotor 4 are formed on the axis of rotation A of the liquid reservoir 2. The rotor 4 is driven by the liquid flowing through the outlet 3. A generator 5 is coupled to the rotor 4 and converts the energy transferred to the rotor 4 by the fluid into electrical energy.
  • the outlet 3 merges into a channel 6.
  • a feed pump To transport the liquid within the channel 6 is a feed pump. 7
  • the generator 5 and the feed pump 7 are electrically connected to a control unit 8. Furthermore, the control unit 8 has a connection to an external network (eg public power grid). The electrical connections are shown schematically in the drawing figures by dash-dotted lines.
  • the control unit 8 can either provide electrical energy generated by the generator 5 to the feed pump 7 or forward it to the external network.
  • the control unit 8 can also, electrical energy from the external network of Provide pump 7 available.
  • the control unit 8 can take over further control and regulating tasks (eg setting the delivery rate of the delivery pump).
  • the downstream end of the channel 6 forms an inlet 10.
  • This inlet 10 opens into an edge region of the liquid reservoir 2 in this.
  • the channel 6 thus carries the liquid flowing through the outlet 3 back to the liquid reservoir 2. Consequently, a liquid circuit is formed.
  • the flow or the flow directions of the liquid are shown schematically in the drawing figures by dashed lines.
  • the liquid located in the liquid reservoir 2 flows through the outlet 3 due to the gravitational effect and drives the rotor 4.
  • spiral flows are generated within the fluid reservoir 2 by the off-center inflow 10 and by flows forming within the fluid (e.g., flows due to the Coriolis force). These spiral flows or vortices generate additional torque on the rotor blades of the rotor 4.
  • the rotational movement of the rotor 4 is converted by means of the generator 5 into electrical energy.
  • the electric energy generated in this way is supplied to the control unit 8. From the control unit 8, this electrical energy can then be made available to the feed pump 7 and / or an external network 9.
  • Fig. 2 shows a further embodiment of a device for energy conversion.
  • the device 21 has a rotationally symmetrical, annular liquid reservoir 22.
  • the vertically lower end of the liquid reservoir 22 is formed as an annular outlet 23. By This outlet 23 can flow out of liquid which is located in the liquid reservoir 22.
  • a plurality of rotors 4 is arranged in the outlet 23 .
  • the rotors 4 are driven by the liquid flowing through the outlet 23.
  • a generator 5 is coupled to each of the rotors 4 and converts the energy transferred by the liquid to the respective rotor 4 into electrical energy.
  • the outlet 23 merges into a channel 26.
  • This channel 26 consists of a vertical, inwardly extending portion and a horizontally extending portion.
  • the horizontally extending portion of the channel 26 is formed on the axis of rotation of the liquid reservoir 22.
  • a feed pump 7 is arranged within the horizontally extending portion of the channel 26. This feed pump 7 is also formed on the axis of rotation of the liquid reservoir 22 and serves to transport the liquid within the channel 26th
  • the generator 5 and the feed pump 7 are electrically connected to a control unit 8.
  • the control unit 8 has the same functionality as the related Fig. 1 described control unit 8.
  • the downstream end of the channel 26 is located on the same horizontal plane as the upper end of the liquid reservoir 22.
  • the liquid leaving the channel 26 can therefore flow to the liquid reservoir 22. Consequently, a liquid circuit is formed (see the flow of liquid visualized by dashed lines).
  • the liquid in the liquid reservoir 22 flows through the outlet 23 due to the gravitational effect and drives the rotors 4.
  • 22 spiral flows or vortices are generated within the liquid reservoir. These spiral flows or vortices produce an additional torque on the rotor blades of the rotors 4.
  • the rotational movement of the rotors 4 is converted by means of the generators 5 into electrical energy.
