Description

Structure for solar tracker.

Object of the invention

The present invention relates to a structure for solar tracker, which in addition to constituting the means of support for the corresponding solar panels, constitutes a support medium on the ground.

The object of the invention is to avoid the classic ones footings or foundations that are traditionally required for the assembly of solar trackers on the ground, as well as allow disassembly of the follower itself without large complications, with minimal dismantling work.

Background of the invention

Normally solar trackers are mounted on the ground by anchoring them on corresponding concrete shoes or similar systems foundation, which obviously means having to make a civil works to achieve a firm and balanced fixation that You must support on the ground.

This fixing system implies that end the life of solar trackers, for example when the contract for the solar exploitation of the plot ends in issue, or because it is necessary to dismantle the solar tracker which has been replaced by new and better benefits features, requires an expensive job of dismantling, in order to leave the ground in the conditions prior to installation and allowing, for example, the realization of agricultural or forestry work, or where appropriate to carry out mounting other solar trackers, or carrying out the lifting a ship or any other type of work or operation that you want to perform on the ground itself.

Therefore, the assembly of followers solar on concrete foundations carries not only costs in the realization of such concrete foundation, but having to carry out an expensive dismantling in the moment when the solar followers have finished their life Useful.

Description of the invention

The structure that has been recommended has been conceived to solve the problem described above, since in first of all it presents the peculiarity that its support on the land does not require foundation of any kind, getting no However, anchor the tracker firmly enough.

More specifically, to get the anchor or fixation of the solar tracker on the ground without foundations, it has foreseen that the structure of the same rests on four legs adjustable arranged at the free end of four arms belonging to a cross frame, so that on that frame or arms carrying adjustable legs is mounted a lattice metal shaft that constitutes the support structure of the solar tracker proper, with the special feature of that to achieve a mass balance of the whole have provided for counterweights.

The lattice shaft has a lower base where he mounts a platform with a chassis for the media of drive that give rise to the azimuthal movement of the follower solar, with the peculiarity that on that platform they are located both the shaft, or what is the same the lower base of it, as the counterweights, arranged in opposition to the extreme area of assembly of the shaft on the platform mounted on the frame in leg bearing cross.

Superiorly the commented shaft includes another frame on which the drive means are mounted for provide the zenithal movement of the follower, and to whose means two side arms are projected, projected in opposition, constituting the supports of the solar panels, Arms that are metal lattice.

Based on the referred characteristics, it avoid having to make foundations and at the same time have them dismantle in case the solar tracker changes place, or it have to disassemble for any reason.

On the other hand, it should be said that in the movement of azimuthal rotation the whole set moves, that is the shaft with its base and of course the platform provided with the counterweights, while in the zenith movement only the arms rotate lattice top to guide solar panels.

In the shaft, and in an area above the base lower of the same, an electrical panel is planned to which has access from the media location area of drive for azimuthal movement, so that by means of that electrical panel a maintenance can be carried out Optimum with simplicity, speed and efficiency.

Finally say that each arm of the frame in carrier cross of the corresponding adjustable support legs, includes a level to achieve the correct leveling of the set of the structure, having also provided that the support legs previously commented instead of stepping directly on the terrain, support on corresponding small slabs Precast concrete.

Leg adjustment is based on a stem threaded over a hole preset vertically in each of the ends of the arms in cross, determining a spindle stabilizer in each case.

Description of the drawings

To complement the description below, will perform and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows a representation according to an overview of the structure for solar tracker carried out in accordance with the object of the invention.

Figure 2.- Shows another perspective view and on a larger scale of the structure represented in the figure anterior, with a different viewing angle to show the correct placement of the drive means, both in the azimuthal movement as in the zenith movement.

Figure 3.- Shows, finally, a detail in perspective of the lower base corresponding to the lattice shaft of the solar tracker, and whose lower base is supported on a rotating crown mounted on the frame equipped with the four Cross arms equipped with adjustable support legs.

Preferred Embodiment of the Invention

As you can see in the referred figures, the structure for solar trackers object of the invention comprises a metal lattice shaft (1), which is complemented by a lower base (2) and an upper base (3), as extensions of the lattice structure or shaft (1), coupling these bases (2 and 3) to the intermediate shaft (1) by bolts.

The bottom of the base (2) is mounted on a platform (4) in turn resting on a crown (5) provided in the center of a frame (6) that includes four arms in cross (7), and equipped with the frame (6) and arms (7) of levels (8) for leveling the structure, since at the end of each of those arms in cross (7) an adjustable support leg is mounted (9) to be conveniently fixed on a prefabricated tile of concrete (10), whose legs (9), in each case, include a stem threaded (11) on an end block (12) provided on each arm (7).

On an extreme area of the platform (4) is where the base (2) of the shaft (1) is mounted, while in a opposite weights of that platform (4) weights are mounted (13).

On the lower base (2) the drive means, consisting of a moto-reducer, to provide the structure of azimuthal movement, by turning on the crown (5), allowing the orientation or rotation of the assembly that forms the shaft (1) with its bases (2 and 3) and the counterweights (13) with respect to the support frame (6) on the ground, while on the upper base (3) they go mounted the drive means for the overhead movement, constituted these means, as in the previous case, by a motor-reducer (15) with two outputs (16) for your coupling to lattice and independent arms (17) located on either side of the described structure, rotating with respect to the corresponding bearings (18), as shown clearly in figure 2, and this allowing the independent rotation of one and another lattice arm (17) and therefore be able to vary the orientation independently of solar panels (19) supported by those arms (17).

Therefore, the zenith movement is made in correspondence with the upper part established on the upper base (3) of the structure, rotating only the arms (17) and with them the panels (19), while the turn azimuthal is done by the whole structure, that is, the shaft (1) with its bases (2 and 3) and counterweights (13), and so both the arms (17) with the panels (19), remaining only  static the frame (6) in which the arms are established (7) of the adjustable legs (9).

Finally, to say that said structure is further complemented by an electrical panel (20) mounted on a side part of the shaft (1), which is accessed directly from the platform (4) to carry out operations, manipulations or drives relevant, access that is direct and secure allowing fast
maintenance.
