    DESCRIPTION
    Object of the invention
    The object of the invention relates to a system for generating energy from the movement of sea waves. 5
    Background of the invention
    In the current state of the art, systems for generating energy from the movement of sea waves that consist of:
    - a floating platform (usually a vessel) carrying at least one rotor shaft acting on an electricity generator; 10
    - at least one buoy attached to the platform by means of an arm; Y
    - mechanical means to transmit the movement of each buoy to the corresponding rotor shaft
    The applicant himself is the holder, among others, of patent documents WO2011131811 and WO2012172131. It is known in patent document WO2011131811 a system that, consisting of the elements described above, employs one or more tanks ballasted with seawater so that when there are no waves these deposits are just at the height of the waterline and when there are deposits, they generate downward forces that add to the downward force generated by the vessel itself.
    An unresolved problem in known systems lies in the difficulty of ballasting and keeping the tanks ballasted (to fill them with water). The object of the invention solves this problem.
    Description of the invention
    The power generation system from the movement of the sea waves, according to the invention, being those consisting of a vessel carrying at least one rotor shaft-25 acting on an electricity generator; at least one buoy attached to the vessel by an arm; and mechanical means of freewheels or ratchets that join each arm to a rotor shaft to transmit the movement of each buoy, is characterized in that the vessel has symmetrically with respect to a plane of symmetry, at least one cavity / reservoir with a lower mouth for water inlet and a lockable top hatch for 30 air outlet; so that once the cavity / reservoir is filled with water, its hatch is closed, leaving the upper surface of each cavity / reservoir just at the height of the waterline.
    From this basic structuring, it is indistinct for the purposes of the invention:
    - that the vessel symmetrically disposes of two cavities / reservoirs spaced from each other on both sides of its symmetry plane, these cavities / reservoir being able to be practiced in the vessel itself or in independent tanks jointly and severally attached to the vessel;
    - that the vessel has a single cavity / reservoir, centered with respect to its plane of symmetry; or
    - that the vessel has a first cavity / reservoir centered with respect to plane 40 of symmetry and additional cavities / reservoir spaced apart from each other on both sides of the plane of symmetry.
    It is included in the object of the invention to arrange several vessels, each of which has any of the structures described.
    Other configurations and advantages of the invention can be deduced from the following description, and from the dependent claims.
    Description of the drawings
    In order to better understand the object of the invention, a preferred embodiment is shown in the attached figures, capable of accessory changes that do not distort its foundation. In this case:
    Figure 1 represents a general scheme of the system object of the invention, for a configuration in which the vessel (2) has a cavity / reservoir (5 ') with a hatch (7') centered with respect to the plane of symmetry (e1). 10
    Figure 2 represents a general scheme of the system object of the invention, for a configuration in which the vessel (2) has two cavities / reservoir (5) with hatches (7) spaced apart from each other on both sides of the plane of symmetry (e1 ).
    Figure 3 represents a general scheme of the system object of the invention, for a configuration in which the boat (2) has a cavity / tank (5 ') with a hatch 15 (7') centered with respect to the plane of symmetry (e1) ; and additional cavities / reservoir (5) provided with hatchways (7) spaced apart on both sides of the plane of symmetry (e1).
    Figure 4 represents a general scheme of the system object of the invention similar to Figure 1, for a configuration variant in which the boat (2) also symmetrically has floats (8), which contribute to maintaining its upper surface (s) just 20 at the height of the waterline (f).
    In all these schemes the system has been represented in a calm position (without waves), to observe its principle of operation.
    Description of a preferred embodiment
    An example of practical, non-limiting embodiment of the present invention is described below. Other embodiments in which accessory changes are introduced that do not distort its foundation are not ruled out at all.
    The system object of the invention basically consists of:
    a) at least one vessel (2) carrying at least one rotor shaft (3) acting on an electricity generator; 30
    b) at least one buoy (1) attached to the vessel (2) by means of an arm (11); Y
    c) mechanical means of freewheels or ratchets that connect each arm (11) to a rotor shaft (3) to transmit the movement of each buoy (1).
    In accordance with the invention, and according to the embodiment shown, the vessel (2) has a plane of symmetry (e1) and has symmetrically at least one cavity / reservoir (5), (5 ') 35 with a lower opening (6), (6 ') for water inlet and an upper hatch (7), (7') for air outlet. The upper hatch (7), (7 ') is closable so that, once the cavity / reservoir (5) is filled with water, (5') its corresponding hatch (7), (7 ') is closed leaving the surface upper (s) of each cavity / reservoir (5), (5 ') just at the height of the waterline (f). 40
    From this basic structuring, any embodiments that do not alter, change or modify the proposed essentiality are included in the object of the invention.
    In the exemplary embodiment shown in Figure 1, the vessel itself (2) defines a cavity / reservoir (5 ’) provided with a lower opening (6’) and a lockable upper hatch
    (7 ’); all focused on its plane of symmetry (e1). In this figure, the boat (2) has been represented with a self-floating structure.
    In the exemplary embodiment shown in Figure 2, the vessel (2) incorporates, in symmetrical arrangement with respect to its plane of symmetry (e1), separate tanks 5 (2a) in which both cavities / reservoir (5) have been defined ) spaced from each other and each provided with a bottom opening (6) and a top hatch that can be closed (7).
    The embodiment shown in Figure 3 is a combination of both previous embodiments:
    - the vessel itself (2) defines a first cavity / reservoir (5 ’) provided with a lower opening (6’) and a lockable upper hatch (7 ’); all focused on its plane of symmetry (e1); Y
    - the boat (2) incorporates, in symmetrical arrangement with respect to its plane of symmetry (e1), second paths cavities / reservoir (5) spaced from each other and each provided with a lower opening (6) and a lockable upper hatch (7 ). fifteen
    In this exemplary embodiment, there are also symmetrically arranged two floats (8) that help keep their upper surface (s) just at the height of the waterline (f).
    The embodiment shown in Figure 4 is similar to that shown in Figure 1, for a configuration variant in which the boat (2) also symmetrically has floats (8), which contribute to maintaining its upper surface (s) just 20 at the height of the waterline (f).
    With any of these structures and arrangement of elements, the ballast of the cavities / reservoir (5), (5 ') is carried out with seawater, which enters freely through the lower openings (6), (6') at the same time which expels the air through the upper hatches (7), (7 ') while they remain open. 25
    When the cavities / reservoir (5), (5 ') are filled with seawater (and there is no air inside), the upper hatches (7), (7') are closed, so that the system is ballasted leaving the upper surface (s) of each cavity / reservoir (5), (5 ') just at the height of the waterline (f).
    For the purposes of the invention, both the way of closing the upper hatches (7), (7 ’) 30 and the means used to do so are indiscriminate.
    Once the generating plant is ballasted and in the sea, at the time that there are waves the boat (2) will tend to rise by the action of the buoys (1). Along with it, the cavities / reservoir (5), (5 ’) will also rise at that time, which, loaded with seawater, already act as ballasted deposits that were just below the waterline (f). These 35 cavities / ballasting tank (5), (5 ') when out of the water add their weight to that of the boat (2) increasing the resistance to the arms (11) of the buoys (1) whose effort is transmitted to the axes that act on the generators (3).
    Although it only appears in Figure 1, the structure of the boat (2) can be self-floating in any of the embodiments, in which case the floats (8) would be optional. 40
    If the cavities / reservoir (5), (5 ') are not filled with water (for example, if only partially filled), the system works (imperfectly, but works) so this possibility is also included in the object of the invention.
    It is included in the object of the invention to have several boats (2) attached or aligned, and joined together forming a single platform; where each of said vessels (2) 45 presents any of the structures described.
    The materials, dimensions, proportions and, in general, those other accessory or secondary details that do not alter, change or modify the proposed essentiality may be variable.
    The terms in which this report is written are true and faithful reflection of the object described, 5 being taken in its broadest sense and never in a limiting way.
