    ROTATING SUPPORT FOR SOLAR FOLLOWER AND SOLAR FOLLOWER AXIS 5 Technical sector
    The present invention is related to solar trackers, proposing an improved rotating support that is used in the rotation of the solar tracker axis on which solar panels support and tilt, the support of the invention has a structural configuration
    10 reduced that allows to align the axis of the solar tracker in any spatial orientation and at the same time minimize the possible mechanical interference of the rotating support with other structural elements of the follower. The support can be applied to any type of solar tracker, such as polar axis followers, azimuthal rotation followers, or other types of solar trackers. State of the art
    In the current market there are different types of solar trackers, for example monospost followers where a panel, or set of panels, are mounted on a single
    20 support, or multiposte followers where several panels, or sets of panels, are mounted on several supports.
    When the installation of solar trackers must be carried out on orographic surfaces with unevenness, or irregularly, problems with the orientation of the axis of the axis usually arise.
    25 solar tracker. This problem is considerably aggravated in the case of multiposte solar trackers, where a single axis is used to support and rotate a set of panels belonging to the same row of the solar tracker, in this case the solar panels occupy a large longitudinal space, of so that excessive time is required to achieve a correct orientation of the solar tracker axis.
    The Spanish patent ES2368402A1, of the same applicant as the present invention, discloses a multiposte polar type follower composed of several rows of solar panels that are supported on a horizontal structure formed by transverse profiles and axes on which the respective rows of solar panels. The axes of the
    35 different rows of solar panels are supported on support posts that go


    driven or grounded. The union between an axis and their respective support posts is made by means of a clamp with a cylindrical outer surface that allows the rotation of the axis so that the solar panels can swing on the axis.
    5 Thus this embodiment allows the shaft to rotate on itself to achieve tiltingof the solar panels, however the cylindrical outer surface of the clamp does notallows the axis to be oriented in any spatial position, but only rotate on itselfsame. To achieve this purpose and to compensate for possible deviations due toirregularities of the land, document US9303684B2 of the same applicant for
    The present invention, which proposes a rotating support comprising a first clamp that has an inner surface with a first spherical shape and a second clamp, housed in the first clamp, which has an outer surface with a second spherical shape that faces with the first spherical shape of the first clamp, so that both spherical shapes allow the axis of the solar tracker
    15 can be oriented in any spatial position.
    This embodiment has a limitation in the positioning of the axis and therefore in the tilting of the panels, since due to the configuration of the rotating support itself, in certain angular positions of the axis, interference between the
    20 rotating support and solar tracker panels, as well as between the rotating support itself and the shaft.
    It therefore becomes necessary a rotating support that allows the axis of the solar tracker to be oriented in any spatial orientation while minimizing mechanical interference
    25 with other structural elements of the solar tracker. Object of the invention
    A subject of the present invention is a rotating support for an axis of a solar tracker 30 comprising:
     a first clamp having an inner surface with a first spherical shape, wherein the first clamp comprises a lower base part and an upper part;


     a second clamp housed in the first clamp that is adapted to receive the axis of the solar tracker, wherein the second clamp has an outer surface with a second spherical shape that faces the first spherical shape of the first clamp, such that the solar tracker shaft is retained
    5 axially in the second clamp with the possibility of orienting in anyspatial position; Y
     a connection profile of the first clamp to a support post of the solar tracker.
    The first clamp additionally comprises a clamping band to join the lower base piece to the upper part and regulate the tightening, and the lower base part has a lower part that is housed in the joint profile. With this structural configuration, an improved rotating support is obtained that allows the axis of the solar tracker to be oriented in any spatial orientation while minimizing mechanical interference with other elements
    15 structural elements of the solar tracker, especially the mechanical interferences between the rotating support and the solar panels that swing on the axis, thus reducing the distance between the axis and the panels, so that the eccentricity and therefore the energy necessary for the movement of the axis of the solar tracker.
    Also a subject of the invention is a solar tracker comprising support posts of the solar tracker to the ground, rotating supports each of them is attached to a respective support post, and a solar tracking axis that passes through the rotating support of each of the support posts, so that a solar tracker is obtained to be installed on irregular orographic surfaces, ensuring that the axis of the solar tracker
    25 stay perfectly aligned.

    5 Figure 6 shows a perspective view of the rotating support of the invention arrangedon a support post of a solar tracker. Detailed description of the invention
    10 Figures 1 and 2 show a rotating support of a solar tracker according to the state of the art. The rotating support comprises a first clamp (100), a second clamp (110) housed in the first clamp (100) and a joint profile (120) of the first clamp (100) to a support post (130) of the follower solar.
    The first clamp (100) comprises a lower base part (101) and an upper clamping piece (102) between which the second clamp (110) is retained, which comprises a first (111) and a second semi bushing ( 112) to receive an axis (140) from the solar tracker. The first clamp (100) has an inner surface with a first spherical shape, while the second clamp (110) has an outer surface with a
    20 second spherical shape that faces the first spherical shape of the first clamp (100), so that both spherical shapes allow the second clamp (110) to be oriented in any spatial position while the axis (140) of the solar tracker is axially retained in the second clamp (110).
    25 The upper clamping piece (102) of the first clamp (100) has wings at its lateral ends (103) with a respective through hole (104), while the lower base piece (101) has extensions at its ends (105) each of which is provided with another respective through hole (106), so that in the through holes (104, 105) connecting screws (150) for fixing both are inserted
    30 pieces (101,102).
    Thus, the first clamp (100) is oversized at its ends to accommodate the connecting screws (150), which can lead to mechanical interference in certain angular positions of the shaft (140). As shown in Figure 2, the 35 panels (160) are arranged close to the axis (140) of the solar tracker as it is in charge


    of supporting and tilting them, and precisely the panels (160) can interfere with the wings (103) of the upper clamping piece (102) in certain angular positions of the shaft (140).
    On the other hand, the joint profile (120) has an upper plate (121) that is fixed by means of the union screws (150) to the lower base piece (101) of the first clamp (100). As seen in Figure 2, the upper plate (121) protrudes perimeter from the lower base piece (101), whereby the upper plate (121) can also interfere with the axis (140).
    An example of embodiment of the rotating support of the invention is shown in Figures 3 to 6, which has an improved structural configuration with respect to the rotating support of the prior art shown in Figures 1 and 2, which allows it to minimize interference mechanical with other structural elements of the solar tracker, and therefore maximize the positions in which the axis (340) of the solar tracker can be arranged.
    The rotating support of the invention comprises a first clamp (300) with an inner surface that has a first spherical shape, a second clamp (310) that is housed within the first clamp (300) and that has an outer surface with a second reciprocal spherical shape to the first spherical shape of the first clamp (300), and a joint profile (320), preferably of a "U" cross-section, which establishes the connection of the first clamp (300) to a support post (330) of the solar tracker.
    The first clamp (300) comprises a lower base part (301), an upper part (302), and a clamping band (303) which is used to attach the lower base part (301) to the upper part (302), so using said tightening band (303) avoids the need to have to oversize the ends of the first clamp (300) to provide connecting screws as required by the state of the art support illustrated in Figures 1 and 2 .
    The upper part (302) has a first ribbed area (302 ’) and the lower base part
    (301) has at its lateral ends a second grooved area (301 '), so that said grooved areas (301', 302 ') allow the clamping band (303) to be retained in the first clamp (300) without possibility of moving from your location.


    The lower base part (301) of the first clamp (300) has a lower part (301 '') that defines a recess for arranging said lower base part (301) in joint profile (320), so that the first clamp (300) is attached to the joint profile (320) without the need to use an upper plate (121) as was the case in the rotary support of the state of the art represented in Figure 2, maximizing the freedom of axis positioning (340) in the space.
    The lower part (301 ') of the lower base part (301) has a first housing (301' '') that transversely crosses said lower part (301 '), while the joining profile (320) has a second housing ( 321) on the wings of the "U" cross section of the joint profile (320), so that in the first housing (301 '') of the first clamp
    (300) and in the second housings (321) of the joint profile (320) a union screw (350) is inserted to secure the fastening of the first clamp (300) to the joint profile (320).
    The first housing (301 '') of the first clamp (300) has a pressure regulating jacket (360), preferably a metal bushing, which is configured to prevent gaps in the joint between the first clamp ( 300) and the joint profile (320), and therefore for the second clamp (310) to maintain an adequate coefficient of friction with the first clamp (300) and with the axis (340) of the solar tracker.
    The second clamp (310) comprises a first semi-bushing (311) and a second semi-bushing (312), between which they define a quadrangular inner surface to receive the axis (340) of the solar tracker. The semi bushes (311, 312) of the second clamp (310) define the outer surface with the second spherical shape that faces the first spherical shape of the first clamp (300), so that the rotation set established between the spherical shapes allows the second clamp
    (310) can be oriented in any spatial position while the axis (340) of the solar tracker is axially retained in the second clamp (310).
    The first clamp (300) is made of a first plastic material configured to resist tensile work, in addition, this part of the rotating support is the one that is most exposed to solar radiation, so the first plastic material is also selected with high resistance to abrasion and sunlight. The second clamp (310) is made of a second plastic material, in this case, the material must have good


    friction properties but you don't have to endure tractions like the first plastic material. The second plastic material is selected to allow the best transmission and produce the minimum friction effort. Being both clamps (300, 310) made of plastic material, the coefficient of expansion of both is similar, which
    5 assumes less friction resulting in a reduction in the energy required to rotate the axis (340) of the solar tracker.
    The lower base piece (301) of the first clamp (300) is a piece injected into the first plastic material that has first rib formations that attenuate the tensile work to which the first clamp (300) is subjected, while the Semi-bushes (311, 312) of the second clamp (310) are pieces injected in the second plastic material, or manufactured with another type of technology, which on the inner surface of quadrangular shape have second ribbed conformations that attenuate the surges to which is subjected to the second clamp (310) due to rotation
    Three-dimensional 15 that can be made by the axis (340) of the solar tracker inside.
    The rotating support can be adjusted in height with respect to the support post (330) of the solar track to which it is attached, for this purpose the joint profile (320) that joins the rotating support with the support post (330) has a vertical correlation of holes torn (322) while the pole
    The support (330) has a correlation of reciprocal holes, so that by selectively aligning said holes the atura of the rotating support with respect to its support post (330) can be regulated.
    The figures show a rotating support with a connection profile (320) to a
    25 respective support post (330) of the solar tracker, however the rotating support could lack the connection profile (320) and be directly attached to its respective support post
    (330) of the solar tracker.
