Definitions

  • the present invention relates to a device for converting the kinetic and/or potential energy contained in water into electrical energy.
  • run-of-river power plants While pumped storage power plants can usually only be installed in mountainous regions and tidal power plants can only be installed near the coast, run-of-river power plants have the advantage that they can, at least in principle, be installed in or on any river. This advantage makes them particularly interesting for a decentralized supply of electrical energy.
  • a certain disadvantage, for example, with the one in the AT 513 995 A1 disclosed river power plants is that a dam must be provided in order to lead the water to the water turbine with a sufficiently high flow speed.
  • the construction of a dam requires considerable effort and can depend on a sometimes lengthy official approval process.
  • the construction of a dam could be rejected due to the comparatively strong impact on nature. Due to the need to provide a dam, it is relatively complex to transfer the run-of-river power plant once installed to another location if this is deemed sensible, for example due to changing flow conditions or other criteria.
  • DE 20 2006 008 201 U1 the DE 20 2019 101 270 U1 , the US 9,534,579 B2 , the US 8,152,441 B2 , the KR 20 0 228 879 Y1 and the CN 1 03 790 756 A referred.
  • the object of an embodiment of the present invention is to create a device for converting the kinetic and/or potential energy contained in water into electrical energy, with which it is possible to remedy the above-mentioned disadvantages using simple and inexpensive means which can be installed, maintained and laid comparatively easily with little impact on nature.
  • the conversion device can, for example, comprise a turbine which is carried by the buoyancy device.
  • the anchoring can cooperate with the buoyancy device, wherein the buoyancy device can define the immersion section.
  • the entire device can be moved on the water surface in the manner of a raft or jetty with comparatively little effort, so that it can be transported to the desired location and installed there with relatively little effort.
  • the device does not require a dam, so that it can go into operation after complete installation without any significant construction work. If the device is to be transported to another location after installation, this can also be done with relatively little effort.
  • the anchoring can be constructed in such a way that the device can be quickly attached to it and removed from it again, for example using hook and eye connections.
  • the device is suitable, for example, for providing electrical energy required for construction projects that are carried out near a river.
  • the device can be moved to a location near which another construction project is being carried out. This makes it possible to ensure the supply of electrical energy even in places where there is no or no sufficiently dimensioned power grid. This can be particularly the case in remote, rural areas.
  • Another application can be in disaster areas where the infrastructure is disrupted, for example as a result of floods or earthquakes, and there is therefore no sufficient supply of electrical energy.
  • the conversion device provides the mechanical energy in the form of rotational energy, which is applied to the shaft.
  • the mechanical energy could also be provided in the form of a translational movement, for example by means of a piston moving back and forth.
  • this translational movement must then be converted into a rotational movement in order to be able to operate the generator.
  • the generator is vertically spaced and in particular arranged vertically above the shaft, thereby providing good accessibility to the generator. This simplifies the assembly and disassembly of the device and maintenance work or even the replacement of the generator, especially using a crane.
  • a modular system can be provided in which differently sized generators with the rest The same device can be used.
  • gears can be arranged between the shaft and the generator, it may make sense, for example, in waters with low flow speeds and/or low volume flows, to use differently sized generators than in waters with higher flow speeds and/or high volume flows. This allows the kinetic and/or potential energy contained in the water to be converted into electrical energy in an optimized manner.
  • the device can have structures which provide different levels.
  • the buoyancy device can have a first buoyancy body and a second buoyancy body, which are connected to one another by means of a frame structure, the first buoyancy body and the second buoyancy body at least partially delimiting the immersion section.
  • the device makes do with two buoyancy bodies, which are connected to one another with a frame structure.
  • the frame structure can be designed like a truss and comprise essentially horizontal and vertical struts and supports.
  • the frame structure makes it possible to connect and separate the two buoyancy bodies quickly and easily.
  • the frame structure itself can also be assembled and dismantled relatively quickly, for example by releasably connecting the supports and struts to one another. Further components of the device such as the conversion device can be attached and/or stored on the frame structure.
  • the immersion section which is at least partially penetrated by the conversion device, is limited by the two buoyancy bodies.
  • the conversion device can be designed so that it does not protrude beyond the two buoyancy bodies. This keeps the probability that the conversion device will be touched and damaged by passing ships, for example, low.
  • the two buoyancy bodies only provide a small resistance to the flow of water, which reduces the slowing down of the flow speed.
  • the kinetic energy contained in the water can be converted into mechanical energy by the conversion device largely without loss.
  • Funnel-shaped baffles can be arranged on the buoyancy bodies, which accelerate the water flowing through between the two buoyancy bodies and direct it to the conversion device.
  • the conversion device can have a water wheel which is immersed in the water, the water wheel being rotatable about an axis of rotation is mounted on the frame structure and the axis of rotation runs perpendicular to the first longitudinal axis and the second longitudinal axis.
  • the conversion device can comprise a turbine, in particular a water turbine.
  • the water turbines usually used for run-of-river power plants are integrated into a canal system, so that they are only suitable to a limited extent for the present device due, among other things, to the space required and the weight.
  • a water wheel on the other hand, interacts directly with the flowing water without the water having to be guided through a canal system.
  • the structure of the present device is kept simple.
  • the water wheel can be removed from the device much more quickly and easily, for example for laying the device, compared to a water turbine.
  • the canal system and the water turbine arranged in it pose a danger to fish.
  • the water wheel on the other hand, is only immersed in the water to a small extent, so that the water wheel does not pose any significant danger to fish.
  • a generator can be mounted at each end of the water wheel.
  • the use of two generators instead of one generator has, among other things, the advantage that the weight of the two generators can be distributed more evenly over the device, thereby making the device is loaded more evenly.
  • smaller and therefore lighter generators can be used, which are easier to transport and assemble than is the case with a larger generator.
  • a further developed embodiment can be characterized in that the first generator is arranged in the area of the first buoyancy body and the second generator in the area of the second buoyancy body.
  • the weight of the generators in question can be introduced more or less directly into the respective buoyancy bodies, without causing major torques. This also contributes to a more even loading of the device, so that the frame structure can be designed in a correspondingly simple manner.
  • the first axle section can interact with the first generator by means of a first gear and/or the second axle section can interact with the second generator by means of a second gear. It is entirely possible to connect the first generator directly to the first axle section and the second generator directly to the second axle section of the water wheel.
  • the electrical energy generated by the respective generators usually depends on the peripheral speed of the rotor relative to the stator of the generator and the speed of the water wheel is comparatively low, the diameters of the rotor and the stator must be correspondingly large in order to provide a sufficiently high peripheral speed can.
  • gearboxes are used, the necessary peripheral speeds can be achieved even with smaller diameters of the rotor and stator due to the gear ratios or reductions.
  • the generators can accordingly are kept small and light, making them easier to transport and assemble.
  • a first hub of the first generator may be arranged at a distance from the first axle section and/or a second hub of the second generator to be arranged at a distance from the second axle section.
  • the space between the axle sections and the hubs can be used, for example, for the gears.
  • the gears can be designed as a spur gear, chain gear or a belt gear. It makes sense to arrange the hubs vertically at a distance from the axle sections.
  • the generators can be arranged vertically above the axis of rotation of the water wheel, which improves their accessibility, especially for maintenance purposes.
  • the volume ratio corresponds at least approximately to the mass ratio
  • the first buoyancy body and the second buoyancy body are immersed in the water to approximately the same distance a, whereby a skewed position of the device and the resulting torques are largely avoided. This contributes to the stability of the device.
  • the anchoring can have compensating elements with which a changing water level can be compensated for.
  • the water level of rivers sometimes changes significantly, particularly depending on the season and weather conditions. This circumstance is taken into account with the compensation means, so that secure anchoring can be achieved regardless of the current water level.
  • the compensating elements can include, for example, springs or piston-cylinder units.
  • the anchoring comprises piles driven into the ground or into the bank.
  • the device can be anchored in a secure manner.
  • the piles can be placed both in the water-covered bottom of the body of water and on the directly accessible bank. It is usually easier to place the piles on the bank, but this may not always be possible, for example on steep banks or if there is not enough space on the bank, for example due to an adjacent road or railway line.
  • a further developed embodiment is characterized in that the anchoring comprises a support structure between the buoyancy device and the piles.
  • the piles can be placed on the bank, where accessibility is better than if they were placed in the water, although such an arrangement is not excluded is. Creating foundations for the piles is also easier on the bank than on the bottom of the water.
  • the forces and moments acting on the device In order to be able to securely fasten the device, the forces and moments acting on the device, which occur in particular during operation of the device, must be reliably transferred to the piles. Depending on the design, the forces and moments must be transmitted over a longer distance, for which a support structure that can include rods, struts and beams is ideal.
  • the support structure increases the flexibility of the placement of the piles.
  • the support structure has a first support section and a second support section, wherein the first support section and the second support section are mounted displaceably relative to one another.
  • the water level of the body of water usually changes depending on the season and weather conditions. Particularly when water levels fall sharply, for example as a result of a longer dry period in summer, larger areas of the body of water can become dry. Then there would be a risk that the conversion device would no longer interact with the water and would therefore not be able to provide electrical energy.
  • the device is anchored exclusively with piles arranged on the bank.
  • the first support section and the second support section can be moved relative to one another so that the device can be arranged further away from the piles. Consequently, the device can be moved further towards the middle of the body of water, where there is usually still enough water flowing.
  • the functionality of the device This can ensure at least within certain limits even at lower water levels.
  • the device has spacers for keeping objects in or on the water away.
  • the spacers can be designed in the manner of a baffle wall. Ships or boats that approach the device are kept at a distance from the device by the spacers so that the ships do not damage the device. Conversely, the ships are not damaged when touching the spacers, as they can have damping elements to cushion the contact. The same applies mutatis mutandis to objects such as tree trunks or other flotsam, which could damage the device.
