Definitions
- the present invention is encompassed within the field of oleohydraulic drive mechanisms, and more specifically, in the field of solar trackers for photovoltaic applications (flat panels, thin sheet, concentration modules, etc.) and thermosolar applications ( heliostats, stirling disks, etc ...) of rotation in one or two axes: azimuthal and / or elevation.
- turning mechanisms are those that allow the movement on two axes: the turning movement of the solar panels on a vertical axis, giving rise to an azimuthal movement, and the turning movement on a horizontal axis giving rise to to a movement of elevation and descent or also called zenith.
- US 612306 which requires a platform for azimuth movement comprising a frame of four beams inside which are located two pivoting hydraulic cylinders connected to two of the corners of the frame, or by ES2322527 , the latter discloses a mechanism of those mentioned above, in which the zenith movement is achieved by actuating a pair of hydraulic cylinders, and azimuthal movement is achieved by the rotation of a ring, driven by a hydraulic motor, attached to a horizontal frame that supports, by means of a plurality of hinges, the support structure of the solar panels, which rotates on a second ring provided with mooring arms.
- the invention relates to a mechanism of rotation of structural supports of compact oleohydraulic operation, preferably for a solar tracker, and preferably to drive the movement in two axes, which allows moving the same surface as other known solar trackers, but with less weight, lower cost, occupying a much smaller space and with a wide range of drive.
- the mechanism of rotation of structural supports oleohidráulico drive of the invention comprises at least two cylinders oleohidráulicos driving movement of rotation of structural supports, such as the structural support of solar panels, with respect to at least one axis, selected from vertical , horizontal, or combination of both. It differs from the oil-hydraulic drive mechanisms known to date in that it comprises a hollow cap, comprising at least one opening on its side surface for the passage of a first and a second pivotable hydraulic cylinder, fixed to the bonnet by means of two axes parallel verticals each cylinder can be arranged at the central point with respect to the upper limit and the lower limit of the cap, which allows to decrease the moment of flexion.
- each oleohydraulic cylinder are fixed by means of connection to a rotating mechanical element selected between rolling bearing or crown, located inside the hollow cap, which is fixed by means of joining this rotating mechanical element, and attached to the support structural by means of union.
- Figure 1 shows a front perspective view of the turning mechanism of the invention according to a first embodiment. > ⁇ - v .. ⁇ Figure 2 shows a rear perspective view of the turning mechanism of the invention according to a first embodiment.
- Figure 3 shows a bottom perspective view of the turning mechanism of the invention, according to a first embodiment.
- Figure 4 shows a front perspective view of the turning mechanism of the invention, according to a second embodiment.
- Figure 5 shows a rear perspective view of the turning mechanism of the invention according to a second embodiment.
- Figure 6 shows a bottom perspective view of the turning mechanism of the invention, according to a second embodiment.
- Figure 7 shows a bottom perspective view of the turning mechanism of the invention, according to a second embodiment without the lower cap of the cap. Detailed description of two embodiments
- the mechanism of the invention comprises:
- a first and a second hydraulic cylinder (5, 6, 105, 106) pivotable, located horizontally with respect to the cap, and fixed to the upper (2, 102) and lower (3, 103) caps of the cap by means of two axes of vertical parallel turns ⁇ 7, 7 ', 107, 107').
- the azimuthal movement, with respect to a vertical axis, is achieved by the rotation of one of the rings of the mechanical element of rotation, in this case a bearing, with respect to its vertical axis.
- This bearing comprises a row of balls between two rings, outside (8, ⁇ 108) and, inside (9, 109), displaced axially with respect to each other, such that the inner ring (9, 109) of the bearing is joined on its upper part to a base platform (16, 116) of a lifting platform (10, 110) by a plurality of joining means acting as support of the structural support, and the outer ring (8) of the bearing is joined at its lower part to the upper cover (2, 102) of the cap, by a plurality of joining means.
- the hydraulic cylinders (5, 105, 6, 106) can be connected at one of their ends, directly to the base of the base (116) as shown in figure 7 of the second embodiment shown in figures 4- 7, in such a way that the base of the bed (16) acts both as a means of joining the bearing to the structural support and as a means of joining the bearing to the first and second cylinders, or by means of a connecting piece (11) fixed to the lower part of the inner ring (9) as shown in figure 3 of the first embodiment shown in figures 1-3.
- the movement of lifting and lowering of the structural support or rotation with respect to a horizontal axis is obtained thanks to a plurality of means of rotation of the structural support which in this case are two lateral arms (15, 15 ', 115, 115') articulated which can be joined by a horizontal axis (12) as it is.
- the mechanism may include:
- the base 116 of the bed can comprise a recess, which can be covered with a lid, and thus allow access to the encoder (117) from the top of the mechanism.
- the hydraulics cylinders and the hydraulic lines, both elevation and azimuth are oriented in such a way that the dull the. movement, -of giFO'.ni 'elevation.
- the lower cover (3, 103) of the cap can comprise threaded holes that allow a quick and easy assembly of the mechanism to the pedestal of the solar tracker or similar
- This mechanism is designed especially for its application in solar trackers, but its extension to other fields of the industry that require similar characteristics is not ruled out. .
