Definitions
- the present invention relates to a wave energy plant for generating electrical energy in the off-shore use and in particular a wave energy plant with a diving platform according to the preamble of claim 1.
- a variety of wave energy systems is known, which differed substantially according to their place of use Depending on whether they are installed on the high seas (off-shore), near the coast or on the coast.
- Another wave energy system is known, which differed substantially according to their place of use Depending on whether they are installed on the high seas (off-shore), near the coast or on the coast. Another
- Differentiation refers to how the energy is extracted from the wave motion.
- buoys float on the water surface so that, for example, a linear generator can be driven by a lifting and lowering movement of the buoy body.
- wave roller a wing is placed on the seabed, which is tilted back and forth due to the movement of the water molecules, for example, the kinetic energy of the wing is converted into electrical energy in a generator "Wave Harrows" is a machine that can be used to transform energy from ocean waves.
- a coupling body such as a wing, a rotor, a roller or the like rotating body is stored such that a
- Orbital movement of the water molecules as a result of sea wave motion is also converted to an orbital motion of the coupling body, which then by a
- the Crank drive can be converted directly into a usable for power generation torque.
- the coupling body can be both a resistance runner and a lift runner, as well as a combination of these variants.
- the tapped usable torque can then, for example, by means of
- CONFIRMATION COPY Hydraulic components and / or be converted by means of a generator into electricity.
- projecting storage are arranged in a common housing or frame.
- the housing or frame has a substantially horizontal longitudinal extent, and is arranged below the water surface.
- By floating bodies in or on the scaffolding, the depth can be varied.
- Such a framework is referred to below as a diving platform.
- the longitudinal extent of the diving platform is sufficiently large to support a plurality of coupling bodies on it, the forces acting on the diving platform act through the orbital motion of the water molecules as a result of the sea wave movement in different directions and cancel each other out largely. This results in a largely quiet position of the diving platform relative to the orbital motion of the
- crank mechanisms of the coupling body can be supported on the largely stationary scaffolding or diving platform and deliver a torque.
- the generated torques of all the individual coupling bodies have the same orientation, since all the coupling bodies have the same direction of rotation.
- the torques generated by the coupling bodies on the crank drives can be added to the dive platform regardless of their point of attack when they attack the same rigid body, as is the case with the known wave energy systems of this design. Due to the same orientation of all coupling body torques, a coupling body total torque thus results according to the kinetic laws, which would put the overall position of the diving platform in a rotation in the direction of rotation of the coupling body. It should be noted that, of course, without the aforementioned torque pickup on the crank drives, the framework is not put into such a rotational movement. Therefore, a particularly advantageous appears Dosability of the torque pick-up, which are described in the following
- Object of the present invention is therefore to keep stable by a suitable means the wave energy plant.
- One goal is to generate by means of this means a corresponding counter-torque, which keeps the wave energy plant and thus in particular the diving platform in position.
- Another goal is to create one
- a further goal is to prevent a combination of the means mentioned in that a torque is induced in the wave energy system, so that the system can be kept in a stable position. Only then would it be possible to profitably tap the torques generated by the coupling bodies on the crank drives and, for example, convert them into electrical energy.
- the above object and the defined objectives are achieved by a wave energy plant with the features of claim 1.
- the basic idea of the invention according to claim 1 is essentially to equip the wave energy plant with a base platform and at least one coupling body which is rotatably mounted, in particular under execution of an orbital motion with a predetermined direction of movement on the platform. Furthermore, an energy conversion device is provided, by which a usable torque for energy conversion can be tapped, i. tapped in the operating state and supported on the platform. Finally, a torque compensation device is provided by means of which a resulting from the tapping / supporting the usable torque reaction torque of the platform is compensated or neutralized.
- the coupling body may e.g. a resistance body or an aerodynamically effective body such as a wing.
- the wave energy plant is provided with a counter torque generating mechanism which is dependent on of the total torque (reaction torque), which is referred to below as (theoretically) usable torque, from the coupling elements generated (tapped) individual torques, applies such counter-torque to the platform, which holds it essentially in a stable (preferably horizontal) position.
- the counter-torque generating mechanism for this purpose has a means for (asymmetric) the aforementioned total torque (reaction torque) counteracting weight transfer or distribution along the platform and / or the frame frame, such that the thus adjustable weight distribution a weight force on the diving platform or the Frame frame which (taking into account the inevitably resulting by the weight distribution lever arms with respect to the geometric center) the usable
- a (trim) fluid accommodated in the dipping platform or in the frame frame can also be pumped back and forth in its longitudinal direction in order to achieve a weight transfer around the geometric center.
- Rotation axis of a coupling body aligned platform end sides) or the frame frame is preferably variable (controllable).
- the buoyancy device is an additional measure acting on the weight distribution device, which enhances or eliminates the effect of the weight distribution device depending on their placement.
- a flexible cable having a specific weight preferably a mooring chain
- a so-called catenery mooring fulfills these requirements, for example.
- Such a mooring chain is thus fixed at a location of the dive platform that would lift in the event of rotational movement of the dive platform, thus increasing the counteracting rotational force of the mooring chain (including the effective lever arm) would increase (ie one parallel to the axis of rotation of a
- the torque compensation device has at least one rotatably mounted on the platform frame frame, on which in turn the at least one coupling body is mounted for orbital motion and on which the counter-torque generating mechanism is arranged, depending on the current tapped usable torque and / or the current spatial position of the frame frame applies such a counter torque on the frame frame, which holds the frame frame substantially stable, so that the platform remains substantially free torque.
- the reaction torque is already compensated ("consumed", or "neutralized") before it is induced in the platform.
- the platform does not necessarily need to be equipped with its own counter-torque generating mechanism.
- This at least one frame frame with a vertical orientation is rotatably mounted on the large horizontal frame. He preferably has (in the simplest case) at its upper end a buoyant body and / or at its lower end a mass, wherein in the small frame of the / the coupling body are held orbitalbewegbar. Of the Torque tap through a gear and / or generator is supported on this small frame.
- an advantageous development of the invention provides for coupling the diving platform with a so-called “heave plate” or damper plate, in which case the fact is made use of that the water molecules in large water depth carry out a smaller or no orbital movement than water molecules close to the water body
- Damper plate coupled via a preferably rigid coupling element with the near the water surface located diving platform causes this stabilization of the diving platform.
- the diving platform can thus build much shorter, without being offset by the wave motion excessively in rocking movements. This is particularly advantageous in terms of cost aspects.

- the frame of the wave energy plant is arranged largely perpendicularly below the water surface in a state without wave motion.
- the at least one floating or buoyancy / ballast tank 18 is disposed at the now upper longitudinal end of the diving platform 1, whereas in this position lower longitudinal end of the diving platform 1 through the mooring 22, such as a catenary mooring , Taunt-Mooring or Tention-Leg-Mooring is attached to the seabed.

- between the two end plates still more discs with the same spatial orientation may be attached to the coupling bodies. This leads to a significantly increased
- the wave energy plant Due to the design of the wave energy plant according to the second preferred embodiment of the invention, it is possible to provide a self-adjusting system with respect to the counter-torque generation, which passively manages without interventional control. As a result, a particularly robust, non-vulnerable system is achieved, which can be designed in particular relatively small. Ideally, the system can work with just one
- the diving platform or the frame 1, in particular according to the first preferred embodiment of the invention a longitudinal extent of up to several 100 m. It is advantageous in this case to tune the length of the diving platform 1 to the expected wavelengths such that it preferably extends over at least two wavelengths. This can be achieved that compensate for the forces acting directly on it and therefore the diving platform 1 is relatively quiet in the water.
- the problem here is the internal stability of Platform 1, which also has to withstand extreme weather conditions such as storms. Large platform lengths thus lead to very high structural costs, which is why according to the invention platforms with lengths (much smaller than) two wavelengths are also considered advantageous. It should also be noted at this point that water molecules close to the
- the diving platform 1 according to the invention is kept in water depths close to the water surface in order to apply the highest possible external forces to the coupling bodies 4 and thus to increase the economic efficiency of the plant. In storms or other events that could lead to an overload, according to the invention, however, also a descent of the diving platform 1 in larger water depths with less

- a damping plate 32 is a flat structure, the highest possible
- This damper plate 32 has flow resistance. This can also be equipped with a perforated surface (perforated, perforated, meshed, etc.).
- This damper plate 32 is oriented horizontally (see Fig. 8) and / or vertically (see Fig. 9) in the water and thus forms a force application surface for the water.
- the coupling device 30 is preferably rigid and is formed for example by perpendicular to the platform 1 extending columns which are fixed to the end of the diving platform 1 and the damper plate 32 in order to transmit tensile and compressive forces can. The thus connected to the diving platform 1 damper plate 32, which is staying in greater depth, thus counteracts a movement of the diving platform 1 damping and keeps them in position.
- the diving platform 1 can thus be reduced in length, which leads to corresponding cost savings on the diving platform.
- a single coupling body combined with such a damper plate The dimensions of the damper plate and the dive platform do not have to match as shown.
- several separate damping plates can be used, which are each connected to the diving platform.
- a different orientation of the damping plate is possible, for example, largely perpendicular or a combination of different

- Buoyancy distribution along the platform 1 is a compensation or counter torque is set to hold the platform 1 in a certain spatial position with respect to the gravity vector and balance. Accordingly, all previous embodiments, the basic principle is based on the platform 1 to generate a torque balance.
- FIG. 10 it is provided to mount rotatably to the platform 1 according to FIG. 1 instead of the coupling bodies shown there at least one (or a plurality of longitudinally spaced apart) frame frames 1a, as shown for example in FIG is disclosed on the platform shown there.
- frame frames 1a (corresponding to small platforms 1) are rotatably mounted at a longitudinal spacing, essentially consisting of two longitudinal rails, which are connected to a lattice frame via transverse beams and on which the coupling body 4 for an orbital movement are mounted relative to the frame frame 1a.
- a longitudinal spacing essentially consisting of two longitudinal rails, which are connected to a lattice frame via transverse beams and on which the coupling body 4 for an orbital movement are mounted relative to the frame frame 1a.
- two Longitudinal rails are used. In principle, one is enough. This could be arranged centrally with two coupling bodies, but it is also enough a side rail.
- the frame frame 1a thus constructed has one or more buoyancy bodies 16 at one longitudinal end and one or more weights (masses) 14 at the opposite longitudinal end, so that the frame frame 1a aligns substantially vertically and thus perpendicular to the (large) platform 1.
- weights masses
- a combination of weight and lift is not mandatory. Even a weight or a lift would be enough.
- the rotatable rack frame 1a is mounted on the platform 1 in its central area.
- the at least one rotatable frame frame 1a is mounted in the region of its lower end (in the region of its additional weight 14) on the horizontal platform 1 (in this case, no weight would be attached here).

- the platform 1 In order to keep the platform 1 as stable as possible in the water, it can be designed with high Cw values at high elongation (this also applies to FIGS. 1 and 2). Thereby forces are introduced into the entire system not only on the coupling body 4 but also on the horizontal frame 1 (platform 1). With a fixed number of coupling bodies 4, this has the advantage that, given a sufficient platform length, a stable platform position is established independently of the current (sea) wavelength, since a substantial proportion of the forces are introduced through the frame.
- the formation of the horizontal frame (platform) 1 as a heave plate with upstanding suspensions 34 for the vertical frame 1a is possible, as shown in Figs. 11 and 12 (is not necessarily a damping plate, can also be simple be a deeper frame). Accordingly, the suspensions 34 by singular support struts (see Fig. 11) or in each case by a framework or
