Abstract

Follower torregiro. Solar tracker characterized by having a structure formed by profiles and removable joints that facilitate, assembly and transport to inaccessible places, and with sufficient height to avoid easy access to solar panels. The follower has several well differentiated parts, a lower one (1) with a wide support surface that is made in several points forming a polygon, and the upper one with two zones, a central one (2) that concentrates the elements that allow the movement in two axes and above this, an area formed by several smaller structures (3) that will be the support surface of the solar panels.

Description

Torregiro follower.

The present invention falls within the sector Power production technician from solar panels or photovoltaic, through mechanisms that allow the rotation in two axes for placing the solar panels in the correct position to capture maximum solar radiation.

Background of the invention

As is well known, solar trackers they are mechanisms that are used to maximize solar energy collected by solar panels supported in a structure that It can have one or two axes of rotation, resulting in so-called followers to an axis, in which the zenith orientation is fixed and the mobile azimuthal orientation, or two-axis followers, in which both movements are allowed.

Using one or the other will depend on the degree of complexity and performance that we want to obtain in our installation.

While the followers to an axis have some simpler mechanisms, also get a lower performance, in around 8% with respect to the two-axis followers that are the which are most used today.

Compared to fixed systems, we have a higher cost due to the structure that generates the movement and the maintaining it, but this initial investment is recovered for the highest performance of the installation, up to 35%.

Although there is a problem with the structures that are used to perform the movement and they are formed for large parts that generate problems when transporting, not for road transport, but for the one that is done from the road to the place where the follower, which requires that the land so that large vehicles can circulate they transport, with the consequent extra cost that generates.

In addition, in the case of having to perform repairs due to any type of inclemency that may affect the follower, these are difficult to do because of the large size of the pieces, not only for the cost they have, but because being such large parts require heavy machinery to be able to repair

Another problem is that the existing technique in Fixed and current mobile systems does not prevent possible theft of solar panels, which are very expensive elements and that represent the greater investment of the facilities, which is due to the placement in isolated places and at low height from the ground to which they are placed. Some solar trackers place the panels at a certain height only when it is night or they occur strong winds, but at the moment the panels are placed in working position are located a short distance from the ground, the enough to be able to access them easily, and although they use methods to prevent their theft, these are sometimes useless because they can also cause the destruction of the panels.

Explanation of the invention.

It would therefore be desirable to get a follower. solar with the advantages of two-axis followers, but without the disadvantages of difficult transport and repair, and of the ease of theft

For this, the present invention focuses on achieve a detachable structure that facilitates handling, transport and repair of the follower, and that in turn, can avoid the easy theft of solar panels without complexes security systems, while achieving a structure resistant, light and low wind resistance, main enemy of all followers.

Detailed description of the invention

The present invention relates to a new solar tracker made with a structure formed with profiles and removable joining elements that facilitate assembly and repeatability in manufacturing, in addition to being removable, allows modify its structure and configure it to place a number panel variable, and in the case of having to make a repair, be able to change only those items that have been damaged.

It is formed by a lower part where they have a series of profiles that will be joined together by removable unions, and that can be joined by others profiles that will be responsible for stiffening the structure. In the top of the structure will be located the engine and all electronic components that will control the movement, being the placement of the electrical panel depending on the configuration of the investors.

In the central part and above the crown of turn, the profiles responsible for supporting the axis that it will allow us the other turn that must have a follower of two axes, the zenith.

On both sides formed structures will be placed also by profiles and removable joints, which can be joined to other auxiliaries to support the grill on which they will be placed solar panels, which are responsible for collecting energy generated by the sun.

This structure by its own configuration is ready to withstand the forces generated in the panels mainly due to the wind, without it being very heavy In addition, the structure itself even with its height allows the free flow of air through it.

Its great height even allows us to save small obstacles that produce yield losses, and as the distance between followers does not depend on their height, it they can continue placing the same number to get the same energy than with other followers of lower height.

Preferred Embodiment of the Invention

In the present invention, the bottom part (1) It is formed by four angles (4) placed in the form of a square, at each end of these, a shoe will be made of concrete with corresponding reinforcements. These angles will be joined together on three levels by angles (5) and plates (6), the flange (7) that supports the rotating crown and the motor that will produce the azimuthal rotation.

The flange will be placed in the central part (2) upper of the rotating crown (8) than by means of a ferrule (9) and a plate (10) will support the angles (11), two on each side, which together each other by plates and in turn both sides by an axis (12), form the structure that will produce the inclination of the follower.

On both sides of this axis (12) there are paths lattices (13) formed like the lower one by angles and plates, which will be responsible for joining two other lattices (14) placed perpendicularly to the previous ones, the latter being those in charge of supporting the grill (15), together with the lattices by means of embossments, on which the panels will be placed solar.

Claims (3)

1. Solar tracker, of the type that by means of the use of a mobile structure that allows the positioning of the solar panels with respect to two axes, and controlling the position by means of electronics, tracks the sun to increase the radiation captured by the panels, characterized due to the fact that it consists of rolled or shaped metal profiles (angles, plates, plates, UPN, IPN, IPE, HEB, HEA, etc ...) and removable joints (threaded elements, bolts, keys, tabs, pins, elastic locks), which form lattice structures both in its lower part (1), being this type tower, as in the upper part (3), in which two parallel lattices that support the grid, are joined by two other perpendicular and separated by the central zone (2), being the union between both where the horizontal turn is made, and the union between the central and lower zone, which will make the vertical turn 2. Solar tracker, according to claim 1, characterized in that it facilitates assembly, repair, and easy transportation to any place without the need for special conditioning of the roads, since by having a removable structure, we can mount, dismantle or transport the pieces independently, being the volume and weight to handle much smaller than in other followers, which allows the handling of the pieces by light vehicles. 3. Solar tracker according to claim 1, characterized in that it is the minimum ground height of the solar panels, even when the tracker is in working position, greater than 3 meters, being considered a sufficient height to avoid easy subtraction of the panels.
