    Object of the invention.The object of the present invention is a device for harnessing the energy of thesea waves that, including floats mounted on armsfolding that are coupled to a horizontal drive shaft by means of respectivemechanisms of transmission of turning movements in one direction only; and whosedrive shaft is mounted with the possibility of turning on pillars ofSupport and connected to an electric generator, presents some peculiaritiesconstruction oriented to allow a height adaptation of the drive shaft andconsequently of the float bearing arms in order tocompensate for differences in tidal height.
    Field of application of the invention.This invention is applicable in the field dedicated to the manufacture of generatorsof energy powered by sea waves.
    State of the artIn the utility model ES 1100855 U of the same holder of the present inventiona device for harnessing wave energy is described, comprisingsaid device: pillars fixed to the seabed and held in its partsuperior a horizontal axis on which they are mounted by wheelsfree some arms that have a float at their end that causesswell effect a reduction of the corresponding arm, which transmits to the axishorizontal the movement of rotation by means of the mentioned free wheels.
    This device requires that the float bearing arms have aimportant length to be able to harness the energy of the waves and absorb theheight differences caused by the tides.
    The use of large arms increases the cost of manufacturing and the space necessary for the implantation of said device, and reduces the performance of the device, since the amplitude of the rotation described by the folding arms due to the swell is reduced as that the length of said folding arms is increased.
    Therefore, the technical problem that arises is the development of a device to harness the energy of sea waves that satisfactorily solve these problems. Description of the invention
    In order to solve the aforementioned problems, the device has been devised to take advantage of the energy of the marine waves of the invention, which being of the type mentioned above presents constructive particularities oriented to allow a height adjustment of the driving axis in order to absorb the differences in height of the water due to the tides, so that the device can obtain a high performance without the need to oversize the length of the folding arms.
    This solution, in addition to improving the performance of the device, reduces manufacturing costs and the space required for its implementation.
    In order to achieve the proposed objectives and according to the invention, this device comprises support pillars of the drive shaft, constituted by a lower, vertical section, attached to the seabed and by an upper section, movable with respect to the lower section and on which the drive shaft is mounted and; pinion-rack mechanisms for height adjustment of the upper section with respect to the lower section of the pillars; in which the pinions are fixed to a motorized horizontal axis, mounted on the lower section of the pillars, and the zippers are geared with said pinions and fixed to the respective upper sections of the corresponding pillars.
    With these characteristics, by driving the motorized horizontal axis, it is possible to vary the height of the upper section of the pillars and consequently of the driving axis and the floats associated therewith by means of the folding arms.
    The folding arms are mounted on the driving axle by means of free-rotating bushings and have actuation tabs of some ratchets fixed to the driving axle and which transmit the turning movement of said folding arms, in a single direction of rotation, to the drive shaft. In this way, when the folding arms ascend by the action of the waves on the corresponding floats, their turning movement is transmitted to the driving axis by the action of the actuating nails on the respective ratchets; Frequently lowering the floats to the initial position when the waves stop acting on these floats.
    According to the invention, the upper section and the lower section of each pillar can be telescopically mounted, the rack of the corresponding rack-pinion mechanism being arranged parallel to the corresponding pillar and fixed longitudinally to the upper section of the pillar.
    Optionally, it is provided that the upper section of each abutment can be hinged on the upper end of the lower section of the corresponding abutment by means of a horizontal axis and possible for tilting, in this case the rack of the corresponding pinion-rack mechanism engaged with the corresponding pinion is found , arranged in an oblique position and fixed by means of a horizontal axis of rotation at an intermediate point of the upper section of the corresponding post.
    In this case, when the motorized horizontal axis is driven, the pinions mounted on it act on the respective zippers that cause a variation of the angle formed by the upper and lower sections of each pillar.
    The drive shaft comprises cardan-type joints for the coupling of successive drive shaft portions, in order to provide the device with a modular character and avoid possible misalignment between the successive drive shaft portions and ensure the transmission of the rotational movement thereof to the Electric generator. Description of the figures.
    To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
    - Figure 1 shows a perspective view of an embodiment of the device for harnessing the energy of sea waves according to the invention provided in this case with telescopic pillars.
    - Figure 2 shows a perspective detail of one of the swingarms carrying the respective floats.
    - Figure 3 shows an assembly detail of one of the tilting arms on the drive shaft in which the ratchets conforming to the rotation movement transmission mechanisms in a single direction can be observed.
    - Figure 4 shows a variant embodiment of the device of the invention in which the pillars have a hinged upper section on the upper end of a lower section of the pillar.
    - Figure 5 shows a detail of the rack and pinion mechanism used in the embodiment of Figure 4 to drive the upper section of the corresponding abutment. Preferred embodiment of the invention.
    In the exemplary embodiment shown in Figure 1, the device comprises three supporting pillars (1) of a drive shaft (2) connected to an electric generator (3),
    found being mounted on said drive shaft (2) several folding arms (4) carrying respective floats (41).
    Each pillar (1) is constituted by a lower section (11) and an upper section (12) telescopically mounted on it.
    The lower section (11) of each pillar (1) is fixed to the seabed by means of a concrete block (13).
    To regulate the height of the upper section (12) of the pillars with respect to the lower section (11) the device comprises pinion-rack mechanisms (51, 52) with the pinions (51) being fixed to a horizontal axis (5) driven by a motor (53).
    In the example shown in the aforementioned figure 1 the zippers (52) are geared with the pinions (5) through windows defined in the lower section (11) of the pillars (1) and fixed to the upper sections (12 ) of the mentioned pillars (1).
    In this case, both the driving axis (2) and the horizontal axis (5) are made up of successive interconnected sections by means of respective gimbal joints (21, 54), which absorb possible misalignments of the successive sections thereof. As can be seen in figure 2, the folding arms (4) carrying the floats (51) have at one of their ends a bushing (42) for assembly with the possibility of free rotation on the drive shaft (2) and tabs (43) for the transmission of the turning or tilting movement, in a certain direction to the drive shaft (2).
    As can be seen in figure 3, the tabs (43) are responsible for driving ratchets (22) fixed to the drive shaft (2) by means of pins (23) so that when the folding arms rotate towards the area upper due to the thrust of the waves on the respective floats (41) the
    tabs (43) transmit this turning movement to the drive shaft (2) by means of the ratchets (22).
    When the waves stop acting on the floats (41) the folding arms (4) descend by own weight without transmitting any movement to the driving axle (2).
    In the variant embodiment shown in FIG. 4, the upper section (12) of the pillars is hinged on the lower section (11) of the corresponding pillar by means of a horizontal axis (14) and enabled for tilting thereon.
    In this embodiment, each rack (52) is engaged with the pinion.
    (51) corresponding, arranged in an oblique position, and fixed by means of a horizontal axis (55) of rotation to an intermediate point of the upper section (12) of the pillar
    (one) correspondent.
    By driving the motor (53) it is possible to move the rack (52) and consequently vary the inclination of the second section (12) of the pillars which results in an ascent or descent of the drive shaft (2) and associated elements the same.
    In the detail shown in figure 5 the zipper portion can be seen
    (52) engaged with the pinion (51) of the horizontal axis (5).
    Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for the appropriate purposes that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration. of the essential features of the invention that are claimed below.
