Abstract

Solar tracker for equipment producing Energy.

The solar tracker includes a mechanism (3) for horizontal movement and other mechanism (4) for vertical movement, so that the interpolation of both movements makes the solar panels of an energy producing team are oriented perpendicular to the sun's rays. Each mechanism is constitutes from a motor reducer (5) or (10) that attacks a transmission (6) or (11) that acts as an element rotary motion transformer in linear motion, so that in the mechanism of horizontal movement (3), the movement linear is used to act on a rack (7) that meshes with a toothed crown (8) to perform the horizontal rotation. In The vertical movement mechanism, the linear movement is used to rotate a connecting rod (12) that acts to perform the rotation in vertical.

Description

Solar tracker for equipment producing Energy.

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a follower solar for energy producing equipment, which has been conceived as a mechanism whose purpose is to achieve the orientation of the bearing structure of photovoltaic panels or panels corresponding to an energy producing team, guidance that will perform both by horizontal axis rotation and by axis rotation vertical.

The object of the invention is to simplify and enhance the functional effectiveness of the mechanisms that perform these turning movements on the horizontal axis and on the vertical axis, to achieve optimal orientation of solar panels or photovoltaic, in addition to high performance.

The scope of the movements in the horizontal axis and in the vertical axis, encompasses all kinds of followers either solar or luminosity.

Background of the invention

Currently, the production teams of photovoltaic solar energy that mount a series of plates or panels in a structure or rotating grill, which follow the path of the sun trying to get maximum radiation from it during the as long as possible, they do it for a two-turn system: a turn horizontal and another vertical.

By interpolating both turns, one of they following the seasonal position of the sun and the other the position time, the optimum orientation of the surface of the panels to the incidence of solar rays.

To get these movements on both axes, currently the technique used are two mechanical turns placed one in horizontal position and another in vertical position, which make up coordinate systems between them.

These turns are driven by gearmotors acting on rotating crowns, said geared motors being in solidarity with a part of the element to rotate, generally the part static, and the crown is integral to the mobile part when making the turn.

By rotating the gearmotor you get that the crown rotates and this in turn drag to the element that the maintains solidarity, that is, the whole grill.

The kinematic chain constituted by commented elements, provides very little robustness to the system when try to turn large surfaces, as is the case with us we refer to a set of photovoltaic panels.

Adopting this solution to beat big torque, the size of both crown and reducer is very large, creating three drawbacks in this type of application:

1.- Occupation of large volume of space for your integration, complicating its adaptation.

2.- Low blocking power when the need of movement requires it (blocking torque).

3.- Possible problem of reversibility of the mechanism when the application does not require it.

Description of the invention

The solar tracker object of the invention presents a series of peculiarities that allow to solve the problems referred to in the previous section, which is a follower type that includes a support structure for panels or plates solar, as well as means that allow a permanent orientation and automatic of said structure and therefore of solar panels, to get sun tracking and perpendicular incidence of the solar rays on the panels themselves, tracking that performed based on the combination of the turning movements in the horizontal axis (parallel to the ground) and on the vertical axis (perpendicular to the ground).

From these general characteristics in yes known, the solar tracker of the invention presents as first feature of novelty the incorporation of the media special to achieve horizontal movement, means that include an electric motor coupled to a reducer, from the which the motor's rotational movement is transmitted to a transmission that transforms rotary motion into linear, being this one used to act, through a zipper, on the periphery of a crown gear or set gear concentrically with the corresponding moving part of the mechanism, so that that linear displacement attack on the referred crown or gear produces its rotation and therefore of the vertical axis or column, thereby achieving the orientation or azimuthal tracking of the sun, so that the rays strike perpendicularly permanently on the surface of the photovoltaic panels.

Another novelty feature of the follower solar, corresponds to special means to get the vertical movement, means including a coupled electric motor to a reducer, from which the motor rotation movement is transmitted to a transmission that transforms the rotary movement in linear, this being used to act, through a system Rotating rod, the vertical rotation of the plate assembly or solar panels arranged on the corresponding grill; that is to say, getting the orientation or zenith tracking of the sun, so that the sun's rays perpendicularly perpendicularly on the surface of photovoltaic panels.

Based on these two mechanisms or devices mechanical, applied to both horizontal movement and vertical movement, the following benefits are achieved:

- Reduction of the volumetric space of the installation.

- Increased transmission capacity of power, thus providing the mechanism with greater durability and reliability

- Increased blocking capacity, getting a high retention torque and balanced when apply external forces on the grill or panel assembly solar.

Description of the preferred embodiment

In view of the commented figures, and doing reference specifically to figure 1, a tower 1 of support for the corresponding grill 2 of the solar panels or photovoltaic, grill 2 that includes a series of profiles forming a structure for said panels.

In any case, on tower 1 they are mounted mechanisms 3 and 4 to achieve the turning movements in the horizontal axis and turning movements on the vertical axis.

Specifically, the horizontal rotation mechanism 3 it comprises a gearmotor 5 whose turning movement acts on a transmission 6 through which the rotary movement is transformed in linear motion, this being transmitted through a rack 7 on which a crown or gear 8 located concentrically to the corresponding rotation axis 9, turning in solidarity with it, to determine the turning movement of such axis and therefore the movement in the horizontal axis.

As for the vertical rotation mechanism 4, the it comprises a gearmotor 10 that transfers the movement rotating to a transmission 11 that transforms said movement rotary in linear, acting on a rotating connecting rod system 12 providing vertical turning movement on the shaft 13.

The positions 2 and 5 are shown of minimum and maximum grinding of the grill 2.
