A largely still position of the submersible platform relative to the orbital motion of the water molecules is thereby obtained. In another plant concept, the so-called “wave roller”, a blade is placed on the seabed, which blade is tilted back and forth due to the motion of the water molecules. Finally, the concept of the “wave harrow” presents a machine by which energy from sea waves can be converted. The kinetic energy of the blade is converted in a generator, for instance, into electric power. Such a plant is planned for offshore use, since here the energy density of waves is particularly high. Advantageous refinements of the subject of the invention are here the subject of the subclaims. For this reason, a dosing facility of the torque tapping which can adapt to the below-described measures for compensating the coupling body torque appears particularly advantageous.

The torque changes also in the event of constant mooring force, as a result of deflection of the weight and/or of the buoyancy body. In addition, the attachment of the mooring chain to a front end of the platform enables this to align itself in accordance with the direction of propagation of the wave such that the coupling bodies are flowed against substantially at right angles. 3 and 4, limited to the shown embodiments, but rather other designs for a drag-type turbine and/or buoyancy-type turbine (or a combination of these), which generate a common rotational direction and a torque aligned in the same direction, can be adopted. The coupling body can be constituted by both a drag-type turbine and by a lift-type turbine, and by a combination of these said variants. For these cases, a change in the weight force of the mooring is not important. 1 and 2, at least on the respectively longitudinally spaced end portions of the submersible platform 1 (at a distance directed perpendicular to the mounting axle 10), buoyancy bodies in the form of ballast tanks 16, 18, or similar air-fillable containers are disposed, wherein at least one buoyancy body on that longitudinal end of the submersible platform which lies opposite the mooring can, where necessary, be sufficient for the working of the plant.
As a result of the plurality of coupling bodies 4 (at least one coupling body is already sufficient for the functionality of the plant), in the represented wave power plant a torque Me is in the present case respectively transmitted in the clockwise direction into the submersible platform 1, in which case the plant according to FIGS. In this case also, the wave power plant consists of a submersible platform 1 having two longitudinally spaced, parallel-running rails 2 (or lattice frame constructions), which are mechanically connected to each other on at least one (axial) end portion by a transverse beam to form a structure (lattice frame), and on the preferably opposite end portion of which are disposed at least one, in the present case two buoyancy bodies in the form of ballast tanks or volume-variable cushions. 1 or 2, the wave power plant of the first preferred illustrative embodiment of the disclosure has a submersible platform 1, which in the present case consists of two parallel-spaced, longitudinally extending rails or beams 2 (also beam-shaped lattice frames), which at least at their respective ends (or else at middle portions) are connected by transverse bars/struts to form a structure (lattice frame).

The length of the lever arm can be adjustable in order to be able to adjust the wave power plant optimally to different wave heights. Finally, reference should also be made to the particular design principle for a wave power plant having a submersible platform 1 according to FIGS. Dolor en caderas y zona lumbar . BACKGROUND The present disclosure relates to a wave power plant for generating electric power in offshore use and, in particular, to a wave power plant comprising a submersible platform. The basic concept of the disclosure consists, essentially in equipping the wave power plant with a base platform and at least one coupling body, which latter is mounted rotatably, in particular with the performance of an orbital motion with predetermined motional direction, on the platform.
In the present case, the at least one coupling body 4 is placed roughly halfway up between the rails 2, yet an arrangement at some other position is also conceivable. In principle, the plant weight is not however adaptable to different operating states unless the plant weight is altered in terms of the center of gravity by the balance weight 20 displaceable along the rails 2 and/or by the pumpable trimming fluid. The movable balance weight can also however be constituted by a (trimming) fluid, which is bunkered in the submersible platform and is pumped back and forth along the submersible platform, for instance by means of a fluid pump.
Alternatively to two rails with coupling bodies arranged in-between, a rail in the form of a middle rib with coupling bodies disposed on both sides can also be provided. For instance, two or more buoyancy bodies can accordingly be fixed to the side of the platform. In the case of a torque pick-off at the coupling body, a reaction moment is induced into the small frame, which reaction moment leads to a tilting motion of the small frame about its rotational axis on the large frame (platform) until such time as the countertorque generated by the buoyancy body and/or the mass via the materializing lever produces an equilibrium of moments.
This leads to significantly enhanced self-alignment and additionally to higher rigidity of the coupling body system. The (each) coupling body 4 can additionally have on its end sides (end faces) a flow guiding element (a type of winglet) 28, preferably in the form of an elliptical disk (does not necessarily have to be circular), which is aligned substantially perpendicular to the coupling body longitudinal axis (bearing axle 6). These circular disks have the task of avoiding a situation in which the water flow “slides off” via the end faces of the coupling bodies and thus of reducing the induced drag (turbulent wake) on the coupling bodies.

It is further advantageous (as already briefly described above) to equip the countertorque generating mechanism, alternatively or additionally to the weight distributing device, with a decentrally disposed buoyancy device (acting non-symmetrically in a direction perpendicular to the rotational axis of a bearing body), the buoyancy force of which upon the submersible platform (i.e. That is to say, the buoyancy bodies/ballast tanks 16, 18 are filled with air such that, if no torque were tapped from the coupling bodies, the submersible platform would pivot counterclockwise from the horizontal into a vertical alignment.

Another aim is the creation of a self-adjusting system, the countertorque of which varies in dependence on the applied torque. At this point, it should be pointed out that the weight force Fg of the mooring chain 22 changes in dependence on its chain length hanging from the submersible platform 1. That is to say that the mooring chain 22 independently applies a force Fg which dynamically opposes a floating motion of the submersible platform 1, whereby the platform 1 is kept in horizontal alignment.
