It should be further noted that the wave period as well as the wave size influences the amount of energy in the waves, therefore the float depth can also be adjusted to wave period as well. This changes the geometry of the system such that the angle α of the connecting lines 4 to the horizontal is greater, which reduces the constraint on the float 2 and consequently increases the natural frequency of the system-making the response of the energy capturing float 2 better tuned to long period sea states. Therefore the angle α, being the angle between the horizontal and respective lines 4 a, 4 b, is adjusted in a similar way to when the distance from the energy capturing float 2 to the reaction member 1 is adjusted as described above.

The results of our computational model of the effect of increasing the distance D3 between the energy capturing float 2 and the reaction member 1 are shown graphically in FIG. Increasing the mass of the energy capturing float 2 generally tunes the response of the float to longer wave periods. 12. It can be seen that increasing the distance D3 between the reaction member 1 and the energy capturing float 2 leads to an increasing period at which the energy capture by the generator attains a peak. It should, however, be noted that any combination of energy capturing float 2 depth; distance between the energy capturing float 2 and the reaction member 1; and distance between the respective pulleys 5 a,5 b,5 c,5 d and the energy converters 3 a,3 b,3 c,3 d is possible. An exemplary hydraulic circuit that can achieve the above requirements is shown in FIG.
The components of such a hydraulic circuit are well known and do not form part of the invention. Various wave devices for generating energy from wave power have been proposed, but such devices have many limitations with no one device having the proven ability to reliably exploit the available wave power resource over the long term. Referring to FIG. 10, in waves having short period, the distance D3 between the energy capturing float 2 and the reaction member 1 is reduced. Referring first to FIGS.

Referring to FIG. 11, in long period waves the distance between the energy capturing float 2 and the reaction member 1 is lengthened. As with the previous embodiment, the distance D3 between the energy generation float 2 and the reaction member 1 can be adjusted independently of the depth D1 of the reaction member 1 by changing the length of the respective connecting lines 4 a,4 c. This is achieved by the mooring lines 9 a,9 b being attached to the reaction member via winches 18 a, 18 b (similar to the winches 13 a,13 b that attach the depth setting lines to the reaction member 1 in the first embodiment). 19 shows the reaction member 1 adjusted to a greater depth by shortening the mooring lines 9 a,9 b. Dolor de rodilla posterior . To allow air to be added to, or removed from, the energy capturing float 2 and the reaction member 1, the depth setting lines 8 a, 8 b can also contain snorkels (i.e.
The large volume of sea water contained in the reaction member 1 imparts to the member a corresponding large mass, and therefore inertia, without increasing its weight W. In addition, the reaction member 1 has a large surface area perpendicular to the direction of the heave force, which thereby provides further resistance to movement by way of a large drag and added mass. Therefore movement of the energy capturing float 2 caused by waves results in relative motion between the energy capturing float 2 and the reaction member 1. This movement is taken up by respective working strokes of the energy converters 3 a,3 b,3 c,3 d and thus exploited to produce power. In any of these plurality of buoyancy modes, the reaction member should have inertia and drag to resist potential movement of the energy capturing float caused by the wave motion.
8, in moderate to large wave heights, the connection lines 4 a,4 b,4 c,4 d may be partially drawn in, so that the depth D2 of the energy capturing float 2 is deeper with decreased wave energy relative to that at the surface, thereby, the structure of the apparatus should not be subject to excess loads and the power take of mechanism should not have to deal with an excess of energy above its rated power. Because the connecting lines 4 a,4 b,4 c,4 d and the depth setting lines 8 a, 8 b are all adjustable in length, the depth D2 of the both the energy capturing float 2 and the depth D1 of the reaction member 1 can be altered independently of each other whilst the entire apparatus remains afloat. 4a, 4b, 4c and 4d is approximately in a circular orbit, it may be the case that the float 2 moves substantially more in surge (horizontally) or heave (vertically) depending on the sea state.
FIG. 13 is a view similar to that of FIG. In the detailed illustration of FIG. Because the surface floats 7 are smaller than the energy capturing float 2, they do not transfer significant loads to the main structure of the reaction member 1 even in very large wave conditions.

1), the reaction member 1 floats on the surface S of the body of water (such as the sea) with sufficient buoyancy for it to carry all other components of the apparatus. The depth setting lines 8 a, 8 b can be adjusted by respective winches 13 a,13 b, thereby allowing control over their length and therefore the depth D1 of the reaction member 1. The length of the connecting lines 4 a,4 b,4 c,4 d, and therefore the depth D2 of the energy capturing float 2, can be adjusted by the respective energy converters 3 a, 3 b,3 c,3 d via the storage of the respective lines on drums such as drum 11 a, which are parts of the respective energy converter.
This leads to a change in the length of the connecting lines 4 a,4 b,4 c and 4 d under the influence of the waves, which in turn is harnessed by the respective energy converters 3 a, 3 b,3 c,3 d to generate useful power. In other words, if it is wished to change the set depth, the setting means may be adapted, modified and controlled such that a further precise depth can be chosen and fixed.
