Description

Solar tracker with lift system by rolling platform on horizontal surface.

Object of the invention

The present invention relates to a follower solar, for photovoltaic panels, with lift system by rolling platform on horizontal surface.

The peculiarity of the follower lies in the chosen lift system, which is done by means of a rolling platform on the pavement, which allows to pass the current followers who have installed photovoltaic panels with a total power between 5 and 10 Kw, to followers as proposed in which powers of 100 Kw can be installed in panels, of one simple and safe way.

Prior art

The alignment of a team with a star is solved for a long time with the different types of mounts that they exist for telescopes used in astronomy.

The orientation of the telescopes is done by turning on two perpendicular axes. The system is called equatorial when one of its axes is parallel to that of the Earth, and altacimuthal when one of its axes is coincident with the vertical of the lu-
gar.

Although in portable telescopes it is used principally the equatorial mount, to be corrected more Easily ground rotation, large telescopes use the altacimuthal system (an axis on the vertical of the place and the another horizontal) for being the most stable system.

The existing followers in the market usually bring the panels on horizontal axes fixed to a frame. The rotation on said axis makes the panels oriented in altitude with the sun.

Azimuth correction is done in two ways basic:

-

Post vertical anchored to foundation shoe. The rack only counts With a central support. The system is used in the mounts of small telescopes Of this type is the support of the follower described in patent ES1058985U.

-

Rail circular on pillars: The frame has rolling supports that They move on the rail. The system is used in the domes of astronomical observatories. Of this type is lift of the follower described in patent ES 1050814U.

For both the automation system in their movements is the same and based on orientation programs automatic telescopes (the "GO TO" function is executed as often as you want to realign the system).

These height lift systems are unstable and that is why the racks used in the they do not usually exceed 140 m 2 with a power of 10 KW in photovoltaic panels.

Explanation of the invention.

The solar tracker object of the invention counts with a support system on a support rolling platform direct to the ground, which allows its construction in large dimensions, equivalent to large panel powers photovoltaic

The platform consists of metal profiles that form a grid, which will have bracing diagonals to avoid deformation in its plane.

In the union of the profiles of the platform they will have bearing wheels with flexible lift system to compensate for pavement irregularities.

The pillars are arranged on the platform, one for each support point, and on these the frame with beams intermediate, on which go the straps or shafts for fixing of the panels.

The follower will have an automation in his spinning movement, starting at sunrise and ending at putting it, when you return to the initial position in  Reverse direction to the one followed during the day. A program will be used standard for azimuth tracking.

The central axis prevents horizontal displacement of the platform, receiving the sliding efforts due to the wind. It will be of small height, so he dumped in It is minimal and does not require a special foundation.

The arrangement of supports at the ends makes the overturning of the structure due to the wind is compensated by the own weight of it.

Brief description of the drawings

Figure 1.- Shows an exploded perspective of the parts that make up the follower: The bottom is the rolling platform, the central part are the pillars and bracings that constitute the bridge beams to support the frame reflected at the top.

Detailed presentation of an embodiment

As shown in the aforementioned figure, the system will consist of a pavement (1) that will be made of Preferred form by concrete screed. On this pavement a central axis (4) is arranged on which the assembly rotates.

The platform (3) is designed for followers of great power, up to 100Kw; the arrangement of profiles is in shape of grid and in its nodes the support wheels (2) are arranged.

The pillars (5) will support the same points of the platform on which the support wheels are arranged and will have lateral bracing (6).

On the head of the pillars a frame (7) to which solar panels (9) are fixed through belts or shafts (8) depending on whether they are fixed or mobile panels.

This whole structure will be metallic, preferably galvanized structural profile with pipes rectangular in beams and platform, and square in the pillars. The  bracing and straps can be shaped profiles "L" "U" etc.
