The apparatus may additionally comprise means of phase control or drag adapted to help and optimize the oscillation, the amplitude and the relative movement of the docked devices in variable or hard maritime conditions. It is desirable that each of these sayings at least two devices comprise a connected surface float of rigid form to at least one body submerged under the float Of surface. As shown in Figure 2, using the example of the submerged body 9, the submerged bodies 9, 10 can additionally comprise means of regulation by means of which can be adjusted the mass of inertia of the containers submerged, for example, the volume of liquid can be regulated trapped in the submerged vessel (s). The floating containers 5, 6 will preferably be Hermetically sealed, internally split, and will present a minimal resistance to breaking or very large waves.

In addition to the energy extraction joints mentioned above, the joining devices can also be provided with elastic joints or chains or dampers or similar adaptations to absorb excessive movements relative in the oscillation, in the swell or in the inclination that they can be caused by the waves that break in conditions of storm; said elastic unions or chains will normally be baggy and you can add weight. Variable flotation apparatus An additional development of devices self-reactive point absorption incorporates a device punctual absorption of three bodies comprising a float of surface, a submerged variable flotation and a mass of inertia. This embodiment presents the additional advantage of allowing the absorption of a large amount of tilt movement and float side energy of surface since it is not inhibited by rigid coupling to a container suspended in depth. One of said devices, built in a rocky gully in the west bank of Pico in the Azores, is a concrete chamber armed partially open on one side below the line of water to the action of the waves.

These provisions may be provisions of power converters of the waves moored individually, which is typically the preferred embodiment for seas with wavelengths predominantly long. However, there is little chance that none of these facilities have an installed capacity greater than two megawatts and the number of suitable places. Combining approximately two of these devices tuned separately, you can get a relatively large phase jump. These two installations seem to be the most developed and perfected WEC systems of this size available. In the alternative form of the apparatus, illustrated in Figure 8, this comprises a single flotation presenting the pointed surface and a virtual mass suspended deeply united by means of energy extraction similar to that which has been previously described. Dolor de hombro por dormir mal . Figure 8 is a schematic drawing illustrating an alternative embodiment of the apparatus according to the present invention equated to a point absorption device but incorporating a virtual mass.
Another degree of freedom is allowed thanks to the pistons that are connected to the central axis 31 by means of a rotating circular element 20, which is adapted to allow the outdoor device to fully rotate in the indoor device Although this turn does not effect Actively changes in energy, improves the conditions of navigation of the entire device in conditions in which relative torsion of connected devices may occur. The inner surface floats 5 and outer 6 result evident, since they are the energy extraction joints 12 that maintain communication between indoor and outdoor devices 3, 4. In this illustrated embodiment, the joints 12 they incorporate 30 hydraulic cylinders and can be connected with a shaft central 31 rigidly connected to the oscillation unit inside.
In terms of practical application, only a few types of devices are currently, or have recently been, in Use or test in European waters. In the international patent application, WO 97/41349 a second variation of the buoy principle is described oscillating In that document, a single oscillating buoy reacts against a column of water trapped in a suspended cylinder vertically below and open at either end, by means of a wide piston that moves reciprocally in the cylinder. The water column moved by the piston acts as a mass of inertia; This arrangement is known as an accelerator tube. This device is known and described in our application for WO 99/28623 international patent. The combination of a variable flotation and a gravitational mass suspended in depth, as is the case in our international application WO 99/28623, you could consider as a single large virtual mass with a mass high gravitational, but with reduced or almost neutral flotation carried out by an associated submerged flotation.

With the final purpose if carried out, it will be necessary to design the basic device of so that its natural frequency is greater (or its shorter period) than that of most waves; then you can use control systems to reduce this frequency, from so that the phase velocity of the device and that of the wave coincide and that the amplitude of oscillation tends towards the optimum for the maximum extraction of useful energy according to the terms. The design imperative is obtain a useful energy at a low cost, that is, optimize the cost of the power unit supplied, instead of trying get the conversion of the maximum amount of wave energy available. The effect of the component dynamic is proportional to the volume of the submerged body 9, 10 and that of the submerged part of the surface float; because said effect decreases with depth, it is desirable to place the submerged body 9, 10 at a depth sufficient to optimize The design and efficiency of the operation.

Surface floats preferably They are of sufficient size and weight to ensure that remain partially submerged in water under conditions of normal wave or swell. The term “virtual mass” indicates weight minimum gravitational and refers to a body that provides a high hydrodynamic ballast or mass of inertia having “mass added “associated with its movement in the fluid. In this way, it provides an ideal spring-mass arrangement, something that until now had not been considered as possible for a floating wave energy converter. Preferably, the total mass, virtual mass and dimensions of each of the devices comprising the surface float, the body or the submerged vessel (s) and the trapped liquid is such that each of them will tend to present a frequency of natural oscillation along its vertical axis that is close at the lower end of the frequency range that corresponds to the mass of the energy of the passing wave.

Point absorption devices can react against the sea floor (located therefore necessarily in relatively shallow water, usually in the proximity of the coast) or they can be floating and react against the inherent inertia of one of its components. The term “surface float” indicates a pointed surface body that is usually at less partially submerged, in which at least part of the Float normally protrudes or projects above the level of the fluid in which said float is located. Each combination of surface float plus the docked submerged vessel, like a floating structure vertically, it will have its own natural oscillation frequency at along its vertical axis, which can be regulated by means of appropriate control and design; each of the devices being stable around a vertical position. The term “rigidly connected” means that the connection between the surface float and said at least one submerged body is rigid enough to transmit compressive and tensile forces.
Preferably, each device comprising a surface float, a submerged body or vessel and a trapped liquid has a general mass, a virtual mass and some dimensions that will tend to have a natural frequency of oscillation along its vertical axis close to the frequency predominant of the surface wave, or it will be provided with a means to alter its natural frequency to match the of the predominant wave type. Que medicamento tomar para dolor muscular . Without However, the incorporation of a large virtual mass, a characteristic of the present invention, facilitates the design of a simple device that has a low cost, with a large capacity installed that matches well with the long wavelength and with the strong ocean waves, and that is suitable for offshore conditions. Due to the large dimensions of the apparatus and its typical distribution under ocean conditions, it can additionally understand navigation lights and reflectors of radar 15 for identification in navigation.

Swing frequency Actual bonding devices can be increased above of its natural frequency through phase control systems, for example, by hydraulic means, so that the apparatus Store to move in phase with the type of immediate wave. This can be done using air springs or hydraulics to temporarily immobilize or dampen the movements of the devices and or to return energy to apparatus at certain stages of the cycle. The devices are designed to be independent of tidal changes in sea levels at which It is intended, they have a minimal dependence on the wave direction, and maximize your return from ocean waves With long wavelength. Object of the invention It is an objective of the present invention provide an improved device for energy extraction of waves or swell in a body of liquid. As such, you can maximize capacity and simplify maintenance of distributed energy conversion devices, which can be place uniquely or in large arrangements.

In the present invention, this combination of submerged flotation and mass Large inertia is replaced by a closed container that presents a reduced intrinsic mass, but that catches a large and, therefore, massive volume of water, acting in this way as A great mass of inertia. From the following detailed description of the attached drawings and the attached claims will result obvious other advantages and features of this invention. Figures 3 to 5 are illustrations of a form of practical embodiment of the apparatus illustrated in Figure 1, except that the energy extraction unions are omitted and the deck superstructures, and a 100 seabed is included as reference. Wave energy converters (WECs) they could also be classified in different ways according to their operating principle and according to how they react to the waves. The resource is greater at sea Wave energy is lost due to the friction with the bottom of the sea as it is having a less depth (a water depth of half of the wavelength or less).
Thus, wavelength is a crucial criterion. 3. outside of the normal area where the waves break, but not in the ocean, is say in the proximity of the coast. A similar device but slightly different, the LIMPET, has been installed on the face of Islay cliffs in Scotland. The submerged body may include a cylindrical compartment 13 that runs through the entire length of the submerged, but airtight container with respect to the remaining part of the airtight container.
