Two-axis solar tracker.

The object of the invention is a new solar tracker to two axes, of new structuring.

In the current state of the art already known solar trackers that follow the path of the sun and that used to improve the production of photovoltaic panels capturing maximum solar energy radiation during the greatest possible time, being able to cite, for example and among others the files ES2253099, ES2219184, ES1062794, ES1061938, ES1061617, ES1061185, ES 1058985 and ES 1050814 in a recent technology and the file P488887, in an older technology.

The known solutions that are part of the current state of the art present complex structuring, with sophisticated mechanisms that make it more complicated and difficult to mount of requiring high maintenance.

The two-axis solar tracker object of the invention simplify known solutions, reducing them both the number of components used and their structuring. Be characterized because it consists of:

a) a base piece, anchored to the ground and constituted in support of the assembly, which defines a raceway provided of guides on which they support and move some twist conductors associated to a lower structure; having this set of driving means to vary the north-south turn with, at least one traction that relates said raceway and said lower structure;

b) a horizontal axis, mounted on said structure bottom with two points of support and turn for a structure superior carrier of the sensors; having this set of driving means to vary the azimuth turn with at least one traction that relates said upper structure and said structure lower;

c) position sensing means capable of capturing the ambient luminosity and, by means of PCB board equipped with electronic circuit controller, transmit orders opportune to the motor means to vary the turns north-south and azimuth adapting the follower in each moment at the optimum angle of capture of a maximum brightness.

From this basic structuring, they are any embodiments included in the object of the invention practices that do not alter, change or modify essentiality proposal.

The two-axis solar tracker object of the invention, In addition, it presents important advantages over known particularly in terms of stability and load sharing, when present a large diameter support base.

Therefore, the two-axis solar tracker constitutes a new invention that involves inventive activity and is susceptible Industrial application

To better understand the purpose of this invention, a preferred form of practical realization, susceptible to accessory changes that do not distort its foundation.

Figure 1 represents an overview Schematic elevation of a two-axis solar tracker according to the invention.

Figure 2 represents a schematic general view in profile, corresponding to Figure 1, with the
upper structure (5) rotated to a different position.

Figure 3 represents an enlarged detail, according to indication of figure 1.

Figure 4 represents an enlarged detail, according to indication of figure 2.

An example of practical, non-limiting embodiment of the present invention. I dont know discarded at all other embodiments in which introduce accessory changes that do not distort its foundation; by On the contrary, the present invention also covers all its variants.

In accordance with the invention and according to the embodiment represented, the two-axis solar tracker consists basically from:

- a base piece (1)

- a lower structure (2)

- driving means (3) to vary the turn north-south of the lower structure (2) with respect to the base piece (1)

- a horizontal axis (4), mounted on said lower structure (2) and with two points of support and rotation (P_ {1}), (P2) for

- a superior structure (5), carrier of the collectors

- driving means (6) to vary the turn azimuth of the upper structure (5) with respect to the structure lower (2) around the axis (4)

- position sensing means capable of capturing the ambient luminosity and transmit the appropriate orders to the driving means (3), (6) to vary the turns north-south and azimuthal adapting the set in each moment at the optimum angle of capture of a maximum brightness.

The relationship of the sensors with the media motor is established through a microprocessor that selects maximum brightness in its two possible directions (from this to west and from top to bottom) and gives orders to act in turn to the engines, through contacts or power stages, in order that the follower is positioned in the selected way (towards the maximum solar radiation or luminosity).

Additionally, the two-axis solar tracker object of the invention includes a safety device that directly or through the media sensors orders the media azimuthal activators (6) place the upper structure (5) in horizontal position in case the wind speed exceeds a preset limit value.

From this conception and structuring basic, elements, means, parts are indistinct and accessories and / or specific components; being included in the object of I invent any practical realizations, with their different dimensions, sizes, shapes and / or arrangement of the elements employees.

In the example -not limiting- of realization represented practice:

- the base piece (1) presents closed configuration, defining a broad support base of great diameter that forms a raceway perimeter (11) provided with guides as rails, in which the twist conductors (21) that are part of the lower structure (2);

- the driving means to vary this turn North-South are, in this case, a gearmotor (3) attached to the lower structure (2) and supported by the said base piece (1) by means of traction (31) which, for the described embodiment, constitutes a game rack / pinion; where the pinion (3a) is mounted on the shaft of output (e_ {3}) of the gearmotor (3) and the rack (3b) goes formed on the outer perimeter of the base piece (1) -see figure 3-;

- the upper structure (5) is mounted with possibility to rotate with respect to the horizontal axis (4) around two support and turn points (P_ {1}), (P_ {2}). The driving means to vary this azimuthal turn they constitute, for this case, a gearmotor (6) arranged in the lower structure (2) and with a tension (61) which, for the described embodiment, the it constitutes an endless / rack set; where the endless (6a) goes mounted on the lower structure (2) and associated with the output shaft (6e) of the gearmotor (6) and the rack (6b) is articulated in (A 6) to structure (5);

- the sensor means employ, for example, plate PCB equipped with controller with electronic circuit and will be in the same plane as the collector plates, that is, they will receive the same solar radiation (photons) as the plates. Your position usual will be screwed to the supporting structure (5), to accompany it along with the plates in the optimal position for the maximum brightness capture. They will be in the part upper structure (5), to be protected from shadows and manipulations;

- the safety device uses, for example, an anemometer, which is a safety element of use frequent in structures exposed to the wind. In this case determines when the wind is excessive for safety structural structure and the correct operation of the follower and powered by the turn provided by the wind itself orders through the control panel the rotation motor action azimuthal, placing the plate set horizontally, so that wind resistance is minimal. Your usual position will be placed on top of the set, in order that capture and accurately determine wind speed.

The materials, dimensions, may vary  proportions and, in general, those other accessory details or side effects that do not alter, change or modify the essentiality proposal.

The terms in which this report is written they are true and faithful reflection of the object described, being taken in its broadest sense and never in a limiting way.
