Description of the invention

A follower is described herein solar, refers to a solar tracker, being of the type of solar trackers that mount the corresponding plates of energy collection used in the field of solar energy, of so that the solar tracker is constituted by a frame, so general triangular prismatic, which incorporates a carrier shaft of a plurality of arms, the rotating axis being, through a series of second impellers, and whose frame is arranged on a support structure, defined by a first tubular body with its closed external base equipped with a circular central projection and provided, on its lateral surface, with a perimeter projection of seat of a first impeller on which a second is arranged tubular body with its external base provided with an extension in the form of a circular crown adjusted to the contour of the circular central projection of the first tubular body, settling on the first impeller the frame.

The series of second impellers, through the which rotates the carrier axis of the plurality of arms over the that the energy collection plates are mounted, they remain for a solidarity side to the frame structure and on the other hand they are solidary to the axis itself.

The first impeller is set and fixed, by one of its sides on the perimeter projection of the lateral surface of the first tubular body, and on the other hand it is fixed to the second body tubular and to the frame, with the side sitting on the shoulder fixed and the solidarity side to the second tubular body and the frame rotary.

On the other hand, to the central circular projection of the outer base of the first tubular body is fixed a section of a first toothed circular crown in which a screw engages endless transmitter of the movement of a first motor mounted on the frame.

Also, to the carrier axis of the support arms of the energy collection plates is fixed, in radial position, a section of a second serrated circular crown that engages in a screw screw transmitter of the movement of a second motor mounted on the frame.

The support arms of the pickup plates of energy and solidarity with the shaft have, on both sides of the shaft, a hinged end section, being aligned by means of a pair of plates.

In this way, it is allowed that in the own factory all energy capture plates are mounted and in the moment of its transport to be able to hinge the arms staying with its ends in vertical position occupying a smaller space.

To complement the description that then it will be done, and in order to help a better understanding of the features of the invention is accompanied by the present descriptive report, of a set of planes, in whose figures in an illustrative and non-limiting manner, the more characteristic details of the invention.

Description of a preferred embodiment

In view of the commented figures and of according to the numbering adopted we can observe how the solar tracker 1 is constituted by a frame 2, in general triangular prismatic, whose frame 2 is arranged on a support structure and on whose frame 2 it mounts, through some impellers, an axis 3 to which a plurality of arms 4.

The frame mounting support structure 2 is defined by a first tubular body 5 that by one of its base it is fixed to the ground and by its other external base it closes forming a circular central projection 6, so that the first body Tubular 5 presents, on its lateral surface and in position radial perimeter, a protrusion 7 on which a first impeller and a second tubular body 8 resting on the first impeller and that by its external base closes, in the form of a circular crown 9, to the projection 6 circular central of the external base of the first tubular body 5.

This first impeller, on the one hand 10, is fixed to the protrusion 7 fixed to the first tubular body 5 and on the other hand 11 it fixed to the second tubular body 8.

In addition, as the extension remains in the form of circular crown 9 of the outer base of the second tubular body 8 in proximity to the contour of the central circular projection 6 of the first fixed 5 tubular body the horizontal forces will be supported by them, allowing to obtain an adequate distribution of efforts, since vertical efforts are supported by the first impeller on the frame support, increasing its useful life to suffer less fatigue its components.

On the other hand, to the projection 6 circular central from the external base of the first tubular body 5 a first section of toothed circular crown 12 in which a screw engages endless 13 transmission transmission from a first engine 14 mounted on the frame 2.

Also, on part 11 of the first impeller supports the frame 2, so that when the first motor 14 is driven the rotation of the screw 13, engaged in the first gear 12 fixed, causes the rotating displacement of the frame 2 with the second tubular body 8 and part 11 of the first impeller, while that section 10 of the first impeller remains fixed together with the first tubular body 5 and shoulder 7 integral with it.

Through this structure in which the second tubular body 8 rests on the first impeller and its external base is close on the projection 6 circular central of the first body Tubular 5 produces a perfect guidance and distribution of forces.

Shaft 3 is mounted with respect to a series of second impellers that are fixed to one of its sides 15 upper frame structure 2 and on the other hand 16 remain fixed to the axis 3 itself that mounts the plurality of arms 4 on which will be arranged profiles that will host the plates of energy collection

In addition, the frame 2 mounts a second motor 17 also provided with an auger transmission screw of the movement to a section of a second toothed circular crown 18 in solidarity with axis 3.

Thus, the first motor 14 will obtain the displacement of the energy collection plates with respect to a vertical plane, while using the second motor 17 you will get the displacement relative to a horizontal plane, orienting the energy collection plates in the most suitable.

The arms 4 integral with the axis 3 have, at both sides of axis 3, a rotating section allowing, as is shown in figure 3 of the designs, which on both sides can leaving the end section of the arms 4 in an upright position. This execution presents an important advantage for transportation, since which, allows to mount the energy collection plates at the factory and carry the fully assembled tracker to be installed with great simplicity and speed.

When the solar tracker is going to be installed, normally, it will be arranged on a base 19 and the arms 4 will remain aligned by pairs of plates 20.
