    5 Azimuthal and lifting mechanism for solar tracker Field of the Invention
    The present invention belongs to the technical field of solar trackers, and more
    10 specifically to the T-shaped solar trackers, formed by a vertical pedestal on which it is mounted, with the ability to turn around the pedestal, an azimuthal rotating support on which in turn a bearing structure of solar panels is mounted, the which has the ability to rotate on a horizontal axis linked to the azimuthal rotating support. The azimuthal turn and the lift turn are achieved
    15 using linear actuators, and the solar panels can be photovoltaic solar panels or heliostat mirrors. The invention relates in particular to an azimuthal and lifting mechanism for solar tracker, with a single azimuthal linear actuator that provides azimuthal rotation and a single linear elevation actuator that provides elevation rotation, such that by only two
    20 linear actuators obtain all the positions of the supporting structure of solar panels required for complete solar tracking. Background of the invention
    25 Solar trackers use mechanisms to position the supporting structure of solar panels in the orientation required to capture the sun's energy. This orientation depends on the geographical situation in which the follower is, the moment (day of the year and time of day) and the solar technology in question (solar thermal
    or photovoltaic).
    30 To give this orientation to the supporting structure of solar panels it is necessary to act in two degrees of freedom, which in most of the mechanisms for solar trackers are azimuth and elevation.
    35 There are currently numerous mechanisms for solar trackers that act


    in azimuth and elevation, which can be classified according to the type of actuator (rotary or linear), the type of actuation (electromechanical or electrohydraulic), the angular path they allow, the load capacity in both retention and actuation, or the precision to follow the sun. All of them have as an objective that, guaranteeing
    5 certain benefits, manufacturing, assembly and maintenance costsbe reduced.
    Documents US6123067, WO2013 / 178850 and ES2495590B1 show mechanisms for solar trackers based on the performance in azimuth and
    10 lifting by hydraulic linear actuators.
    The mechanism described in document US6123067 has a frame that rotates around the follower pedestal, actuated by two hydraulic cylinders for the movement of azimuth that allow a 360º azimuthal movement. He
    The mechanism has a third hydraulic cylinder that drives the lifting movement in an approximate range of 90º, so that it can position the supporting structure of solar panels in any lifting position between 0º (horizontal position) and 90º (vertical position).
    20 WO2013 / 178850A1 discloses a mechanism with hydraulic actuation in materialized azimuth by means of two linear actuators joined in the same common axis, but at different height to allow them to cross, and that allows a complete 360º rotation of the panel bearing structure solar with respect to the support pedestal. In addition, the mechanism is completed with a third linear actuator
    25 to perform the lifting movement in an approximate range of 90º, as in the previous mechanism.
    Document ES2495590B1 discloses a mechanism with hydraulic actuation in materialized azimuth by means of at least three hydraulic cylinders located in a
    30 same horizontal plane that joins the same common axis and that allows a complete 360º rotation of the supporting structure of solar panels with respect to the pedestal. In addition, the mechanism has an additional hydraulic cylinder to perform the lifting movement in an approximate range of 90º, as in the previous mechanisms.


    All these mechanisms have an elevation range of approximately 90º and are able to position the supporting structure of solar panels with the different orientations required at each moment throughout the year thanks to the fact that their azimuth drive allows a rotation of approximately 360º with respect to the pedestal.
    However, this need to rotate approximately 360º in the azimuthal axis, which must be accompanied by the ability to apply or retain the necessary loads to maintain the desired orientation at each moment and by the stiffness required to guarantee accuracy in any of the orientations, makes it necessary to use at least two linear actuators to drive the azimuth axis, which makes the mechanism more expensive.
    On the other hand, the use of these two or more actuators to activate the same degree of freedom means that the mechanism is over acted on azimuth, which implies a complexity in the control, since the commands of the different actuators must be well coordinated of azimuth to avoid undesirable internal efforts, and a complexity in the assembly, since all the actuators must have the pistons in the correct position to be able to mount them in the common axis.
    It is therefore desirable a mechanism for solar tracker that, being able to give the supporting structure of solar panels the desired orientation at every moment and having the ability to apply or retain the necessary loads and the rigidity required to ensure accuracy, need less actuators, allow easier control, be easier to assemble and require less maintenance, all of which will lead to cost reduction. Description of the invention
    The present invention solves the problems existing in the state of the art by means of a mechanism of azimuthal rotation and elevation for solar tracker as described in claim 1.


    The azimuthal and lifting mechanism for solar tracker is configured to support a supporting structure of solar panels and provide an azimuthal rotation of the supporting structure around a fixed vertical axis arranged on the vertical pedestal of the solar tracker by means of azimuthal rotation, to proportionate
    5 additionally a lifting rotation of the supporting structure in a range greater than90º that allows to tilt the supporting structure of solar panels both forward(according to figure 1b) as backwards (according to figure 1c), around a horizontal axis ofmobile lifting by means of lifting rotation.
    10 The solar panel bearing structure is tilted forward when the solar tracker is in intermediate positions between the positions of Figures 1a and 1b, while the solar panel supporting structure is tilted back when the solar tracker is in intermediate positions between the positions of figures 1a and 1c.
    15 The azimuthal rotation means are formed by a fixed part that is rigidly connected to the vertical pedestal, and by an azimuthal rotating support attached to the fixed part by means of a rotation element.
    20 The azimuthal swivel stand is configured to rotate around the axis of the pedestal. Furthermore, in said azimuthal rotating support the horizontal axis of mobile lift is arranged around which the lifting rotation of the supporting structure is made.
    25 The fixed part can be integral with the vertical pedestal of the solar tracker, or be an independent part of it. As for the turning element, it is preferably made by a raceway formed in turn by an inner ring and an outer ring.
    In addition, the azimuthal rotation means have a single horizontal azimuthal linear actuator, which is preferably a hydraulic cylinder, whose sleeve is articulated through a first vertical joint to the azimuthal rotating support, and whose piston is connected through a second vertical joint. around which you can turn to a first articulated set. This first articulated set in turn comprises
    35 a first articulated bar, which is attached to the fixed part by a third


    fixed vertical joint, and a second articulated bar, which is attached to the first articulated bar by means of a vertical joint and to the azimuthal rotating support by means of a fourth vertical joint. These azimuthal rotation means by means of a single linear actuator and the articulated assembly provide a rotation around the axis
    5 vertical of about 180º.
    According to different embodiments of the invention, the azimuthal linear actuator and the first and second articulated bars can be arranged in the same plane, or in different planes.
    In accordance with a particular embodiment of the invention, the azimuthal linear actuator joins the first articulated bar and the second articulated bar of the first articulated assembly directly through the vertical joint. Alternatively, the azimuthal linear actuator joins the first articulated bar or the second bar
    15 articulated of the first articulated assembly by means of the vertical articulation, the two articulated bars being joined together by an additional fifth vertical joint different from the second, third and fourth vertical articulation. This would simplify the connection between the two bars and the linear actuator by adapting it to different sizes of mechanism and / or simpler manufacturing processes.
    The lifting rotation means have a linear lifting actuator, which is preferably a hydraulic cylinder, and which is perpendicular to the horizontal axis of mobile lifting, and according to the preferred embodiment of this invention is articulated to the azimuthal rotating support and the supporting structure of solar panels
    25 through paths parallel to the axis of elevation. These lifting means of rotation provide a turning range of more than 90 °, that is, they can tilt the supporting surface of solar panels also to the rear. Therefore, these lifting means of rotation provide a rotation of the supporting structure of solar panels by positioning it with an inclination both forward and backward. This turn of
    30 more than 90º is obtained with the appropriate configuration and length of the linear lift actuator.
    According to another particular embodiment of the invention, alternative to the previous one, this linear lifting actuator is articulated by a first horizontal joint to the
    35 azimuthal rotating support and the piston of said linear lifting actuator is attached to


    through a second horizontal joint around which it can rotate, to a second articulated assembly. This second articulated assembly in turn comprises a third articulated bar, which is attached to the supporting structure by means of a third horizontal joint, and a fourth articulated bar, which is connected to the
    5 third articulated bar by means of a horizontal joint and the azimuthal rotating support by means of a fourth horizontal joint.
    According to different embodiments of the invention, the linear lifting actuator and the third and fourth articulated bars can be arranged in the same plane, or
    10 in different planes.
    According to a particular embodiment of the invention, the linear lifting actuator joins the third articulated bar and the fourth articulated bar of the second articulated assembly directly through the horizontal joint that
    15 join the bars together. Alternatively, the linear lifting actuator joins the third articulated bar or the fourth articulated bar of the second articulated assembly by means of the horizontal joint, the two articulated bars being joined together by an additional fifth horizontal joint other than the second, third and fourth horizontal joint
    Therefore, according to the invention, the mechanism comprises only two linear actuators, which can be hydraulic or electromechanical, one in charge of performing the azimuthal movement and the other in charge of performing the lifting movement. The main advantage of the present invention is that it avoids the need for
    25 use at least two linear actuators for azimuthal movement since the necessary range of azimuthal movement is reduced to values around 180º because the mechanism has a range of movement in elevation greater than 90º, that is, it has the capacity to tilt the supporting structure of solar panels forward and backward. This is possible because, for example, the result of a
    30 rotation in azimuth of 180º and a subsequent forward rotation of 30º in elevation is equivalent to a backward rotation of 30º in elevation, as can be verified taking into account the forward and backward positions of Figure 1.
    The range of movement in elevation can be adjusted according to the needs, 35 according to the geographical coordinates where the follower is implanted, the dimension of the


    solar plant where the tracker is installed, etc. The most usual lifting movement will be between a forward inclination of about 90 ° from the horizontal position and a backward inclination of about 45 ° from the horizontal position.
    5Other advantages derived from using a single actuator in the turning movementazimuthal are that, since it is not an over acting actuator, its control is moresimple and its assembly is easier than in the existing mechanisms currently.
    10 In addition, the use of only one actuator for each degree of freedom simplifies the mechanism and reduces its maintenance needs.
    All of the above advantages translate into a reduction in the cost of the mechanism, both in manufacturing and assembly and maintenance. 15 Brief description of the drawings

    The object of the present invention is an azimuthal and lifting mechanism for solar tracker.
    As the figures show, the rotation mechanism 3 for solar tracker is
    15 configured to support a bearing structure 1 of solar panels and provide said bearing structure 1 with an azimuthal rotation about a fixed vertical axis arranged on the vertical pedestal 2 of the solar tracker by means of azimuthal rotation, and a lifting rotation in both directions (that is, "forward" and "backward") about a horizontal lifting axis 17 moving by means of lifting rotation. The
    Figure 1 shows different positions of the solar tracker that allows the azimuthal rotation and lifting mechanism object of the present invention.
    The azimuthal rotation means have a fixed part 14 rigidly connected to the pedestal 2 and an azimuthal rotating support 6 connected to the fixed part 14 by means of a rotation element 25 13.
    The azimuthal rotating support 6 is particularly constituted by a cylindrical wall housing, in which an opening is made for the passage of the azimuthal linear actuator 4, and is configured to rotate about the axis of the pedestal 2. Furthermore, in
    30 said azimuthal rotating support 6 is arranged the horizontal lifting axis 17 movable around which the lifting rotation of the supporting structure 1 is made.
    The fixed part 14 can be integral with the vertical pedestal 2 of the solar tracker, or alternatively be an independent part thereof, as can be seen in Figure 5.


    As for the turning element 13, it is preferably made of a raceway which in turn comprises an inner ring 19 and an outer ring 20, as shown in Figure 5 and Figures 7 to 10. According with a particular embodiment 5 of the invention the inner ring 19 of the raceway crown is fixed to the fixed part 14 while the outer ring 20 is fixed to the azimuthal rotating support 6. According to an alternative embodiment, the inner ring 19 of the raceway is fixed to the azimuthal rotating support 6 while the outer ring 20 is fixed to the fixed part 14. Alternatively to the raceway any other could be used
    10 known rotating support system.
    Additionally, the azimuthal rotation means have a single horizontal azimuthal linear actuator 4, which is preferably a hydraulic cylinder, and which is articulated through a first vertical joint 8 to the azimuthal rotating support 6. To facilitate the
    15 mounting of this first vertical joint 8 supports 7 of the linear actuators rigidly attached to the azimuthal rotating support 6 are used, as can be seen in Figure 5.
    The piston of the azimuthal linear actuator 4 is connected through a second joint
    20 vertical 11 around which it can rotate, to a first articulated assembly. This first assembly is in turn formed by a first articulated bar 9, which is connected to the fixed part 14 by means of a third fixed vertical joint 12, and a second articulated bar 10, which is connected to the first articulated bar 9 by a vertical joint and the azimuthal rotating support 6 by a fourth joint
    25 vertical 15. This configuration of the azimuthal rotation means can be observed in detail in Figure 5 and Figures 7 to 10.
    According to a preferred embodiment of the invention, the azimuthal linear actuator 4 and the first articulated bar 9 and the second articulated bar 10 are arranged in
    30 the same plane, as can be seen in Figure 5. Alternatively, the azimuthal linear actuator 4 and the first articulated bar 9 and the second articulated bar 10 are arranged in different planes.
    Figure 5 and Figures 7 to 10 show a preferred embodiment of the invention, in which the azimuthal linear actuator 4 joins the first articulated bar 9 and the second


    articulated bar 10 of the first articulated assembly directly through the second vertical joint 11 which is also used to join the first articulated bar 9 and the second articulated bar 10 together. Figure 11 shows an alternative embodiment of the invention in which the azimuthal linear actuator 4 can be attached to
    5 the first articulated bar 9 or the second articulated bar 10 of the first articulated assembly by means of the vertical joint 11, while the two articulated bars 9,10 are joined together by an additional fifth vertical joint 21 which is different from the second vertical joint 11, to the third vertical joint 12 and the fourth vertical joint 15.
    10 As for the lifting rotation means, these are responsible for carrying out the lifting rotation of the supporting structure 1 around the horizontal axis of mobile lift 17 arranged in the azimuthal rotating support 6, by means of a linear lifting actuator 5, which preferably it is a hydraulic cylinder perpendicular to the mobile horizontal axis
    15 17, which according to the preferred embodiment of the invention is articulated to the azimuthal rotating support 6 and to the supporting structure 1 by means of articulations 16 and 18 parallel to the elevation axis 17, and which does not intersect with the elevation axis
    17. Since the horizontal axis of elevation 17 is in the azimuthal rotating support 6, it is mobile and moves with the azimuthal rotation, all the components and joints that
    20 govern the elevation rotation revolve around the azimuthal vertical axis. Figure 6 shows this embodiment.
    According to another particular embodiment of the invention, alternative to the previous one, this linear lifting actuator 5 is articulated by a first horizontal joint 16 to the
    25 azimuthal rotating support 6, and the piston of said linear lifting actuator 5 is connected through a second horizontal joint 18 around which it can rotate, to a second articulated assembly. The first horizontal joint 16 and the second horizontal joint 18 are parallel to the horizontal axis of movable elevation.
    30 This second articulated assembly in turn comprises a third articulated bar 24, which is attached to the supporting structure 1 by a third horizontal joint 25, and a fourth articulated bar 22, which is connected to the third articulated bar 24 by a horizontal joint and azimuthal rotating support 6 by means of a fourth horizontal joint 26.


    According to different embodiments of the invention, the linear lifting actuator 5 and the third articulated bar 24 and the fourth articulated bar 22 may be arranged in the same plane, or alternatively they may be in different planes.
    5 According to a variant of the embodiment of the invention, the linear lifting actuator 5 joins the third articulated bar 24 and the fourth articulated bar 22 of the second articulated assembly directly through the horizontal joint 18 which is also used as the horizontal joint linking the third articulated bar 24 and the fourth articulated bar 22. Alternatively, the linear lift actuator 5 joins
    10 to the third articulated bar 24 or to the fourth articulated bar 22 of the second articulated assembly by means of the second horizontal joint 18, while the third articulated bar 24 and fourth bar 22 are joined together by an additional fifth horizontal joint 23 different from the second horizontal joint 18, third horizontal joint 25 and fourth horizontal joint 26. Figure 12 shows this
    15 realization.
    Once the invention is clearly described, it is noted that the particular embodiments described above are subject to modifications in detail as long as they do not alter the fundamental principle and essence of the invention.
