DESCRIPTION

Photovoltaic solar tracker.

Object of the invention

The present invention refers to a photovoltaic solar tracker, the obvious purpose of which is to form part of a solar field for the capture of solar radiation and to obtain usable energy for any use.

The object of the invention is to achieve a structurally simple, robust and compact solar tracker, which is capable of rotating on the vertical axis, while remaining fixed on the horizontal axis. Background of the invention

As is known, in a conventional photovoltaic solar tracker a grid is established, commonly called "solar field", where the photovoltaic modules are held, defining a flat and rigid support.

Said grills, usually structured based on steel profiles, and arranged in a reticular manner, can be assembled in two different ways, with the ability to rotate on the vertical axis and with the ability to rotate on the horizontal axis, or with the ability to rotate on the horizontal axis. axis only vertical, so that in the first case the orientation of the solar field towards the sun's rays is carried out throughout the day and throughout the year, while in the second case, that is, when it rotates only on the vertical axis, the orientation or solar tracking is only throughout the day.

Specifically, in this second type of solar trackers, that is, those that are only oriented or rotated with respect to the vertical axis, it can be said that they are still simpler than those that are oriented both on the vertical axis and on the horizontal axis, without However, most of the time they suffer from a fragility that represents a danger in the face of strong winds, loads as a result of snow, etc. Whereas if the general structure of the tracker is given robustness, the assembly is expensive, very heavy and enormously complex. Description of the invention

The advocated solar tracker has been conceived to solve the aforementioned problem, since it has a simple but at the same time robust and compact structure, being able only to rotate on the vertical axis in order to accompany the movement of the sun along the throughout the day, remaining fixed and with a certain inclination regarding its orientation with respect to its horizontal axis, and whose orientation or inclination is previously established to achieve optimum solar field performance.

Structurally, the solar field or photovoltaic panels are supported on a plurality of struts that run parallel to each other in an upward / downward direction, according to the fixed inclination of the solar field, and transversely to these struts are ribs fixed below them and narrowing accordingly. the central zone towards the ends, so that this structure is supported by a trapezoidal frame with internal diagonal stiffening cross members, that on one of its sides is joined by welding to the lowermost rib of those that includes the structure, while on the opposite side of that trapezoidal frame two inclined arms are projected that end in the intermediate rib, establishing the fixed inclination of the field solar.

In addition to the structural characteristics referred to for the solar field, it has the particularity that several rolling skids are established on the frame that slide on a circumferential T-profile rim, located below and anchored on the upper surface of a foundation slab. with the particularity that the skates have wheels that slide so much on the upper surface, as on the lower surface of the check mark corresponding to the “T” of the circumferential rim, to prevent the frame from tipping over with the air. The aforementioned rim through which the skates linked to the frame slide, has the typical pins that are embedded in the mass of concrete that constitutes the referred foundation slab.

The solar tracker materialized in the way described, is structurally simple, with enough robustness and resistance to allow its functionality without being altered by inclement weather, such as the wind, load of the solar field as a result of snow. , etc., being furthermore rotatable on the vertical axis in an optimal way, by virtue of the sliding skids on the circumferential rim established below.

Description of the drawings

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. For illustrative and non-limiting purposes, the following has been represented:

Figure 1.- Shows a representation according to a rear perspective of the solar tracker made in accordance with the object of the invention.

Figure 2.- Shows an enlarged detail, also in perspective, of the fundamental part of the structure of the solar tracker, seen from an angle other than that of figure 1.

Preferred embodiment of the invention

As can be seen in the referred figures, the solar tracker comprises a support structure for a solar field (1) formed by the photovoltaic panels that remain in a plane orientable to the sun to capture solar radiation and obtain energy as is conventional.

The supporting structure of the referred solar field (1) is constituted by a plurality of braces (2), parallel to each other and under them some ribs (3) that, as can be seen in detail in Figure 2, present their intermediate part of the The same width but taper towards the ends, specifically the two located below, since the one located above has a constant width.

These ribs (3) are complemented by another pair of ribs (3 ') in the direction of the braces (2), thus forming a rigid, compact and at the same time simple structure.

All this structure with the solar field (1) is supported by a frame (4) with a trapezoidal configuration, through one of whose sides it is fixed by welding (5) to the lower rib (3), as seen in detail in figure 2, this frame (4) being internally stiffened by oblique profiles (4 '), while on the opposite side to that of the

ES 1 065 162 U welds (5) a pair of arms (6) are projected, with an upward inclination, determining together with the fixed points that constitute the welds (5) the means of inclination of the solar field (1), inclination that must be average so that it stays that way throughout the year, since throughout the day the solar field rotates on the vertical axis to follow the sun from sunrise to sunset. This frame (4) supports the entire structure of the solar panel, has skids (7) that slide on a circumferential rim (8) with a T-section, whose skids (7) are equipped with both lower (9) and lower wheels. (10) with respect to the tilde of that T-profile of the circumferential rim (8), providing that support above and below the wheels (9) and (10) an anti-tip safety for the solar panel assembly, that could be produced by the effect of strong winds.

Finally, to say that the rim (8) is equipped with a plurality of pins that are embedded in a mass of concrete (11) constituting the corresponding foundation slab.
