    Bearing for solar modules. It is already known to mount rigid connecting shafts between solar modules on pulley-bearing stands in a solar power station. However, with the coupling shafts decoupled, this requires a special construction with two pulley stands arranged next to each other. This will be avoided according to the invention. To this end, the invention envisages forming an outer shaft as tubes and mounting an inner shaft on it through a terminal shell element, so that it is housed in the outer shaft in a longitudinally movable and tiltable manner, as well as, if necessary, free of rotation. To do this, only one pulley stand is necessary, even when two uncoupled drive shafts are mounted. (Machine-translation by Google Translate, not legally binding)

    [0004] The present invention relates to a bearing for the rotationally movable support of solar modules in solar power plants, which comprises a pulley stand and a transmission shaft mounted thereon for the connection of two adjacent solar modules.
    [0005] Such a bearing is already known from the state of the art. Thus, document EP 1754 942 B1 already shows a primary mirror bearing with a pulley stand, on which a drive shaft is mounted. The rollers mounted next to each other on a trough profile jointly serve as a support for the drive shaft, which is in contact with the two and, thus, is housed in a defined position. For protection, it is installed with a bracket, a third roller from above on the drive shaft.
    [0006] Such a bearing serves to link two primary mirrors coupled to each other through the drive shaft. With this, it is sufficient to follow the height of the sun with one of the primary mirrors, so that the following primary mirrors, rigidly connected to it, follow it. In other cases, it is instead known to follow the mirrors individually or to make at least one subdivision into several groups of mirrors, which are decoupled from each other. For this, it is necessary, according to the state of the art, to provide two independent pulley stands for the separate transmission shafts and, thus, to facilitate a special construction for these cases.
    [0007] In addition, although it is already foreseen in the state of the art, pass the PTO shaft, with a corresponding slope, also with an inclination through the pulley stand, however, an exactly linear orientation of the primary mirrors to each other is always required, however.
    [0008] In this context, the present invention is based on the aim of proposing a simpler, but nevertheless more flexible solution, for a bearing for solar modules, in particular primary mirrors or photovoltaic elements, which both dispenses with a special construction in the field of decoupled, juxtaposed solar modules, as it can also bridge a slope between them.
    [0009] This is achieved by means of a bearing for the rotationally movable support of solar modules in solar power plants according to the characteristics of claim 1. Useful configurations of such a bearing can be deduced from the dependent claims that follow.
    [0010] According to the invention, it is intended that a bearing for a solar module with a single pulley stand is sufficient, even when two adjacent primary mirrors, photovoltaic elements or other solar modules are still decoupled from each other. This is achieved by the fact that the transmission shaft is mounted on the pulley support stand in two cooperating parts, specifically a tubular outer shaft, in whose inner space an inner shaft is housed. For this, the inner shaft has at its end facing the outer shaft, a shell element, preferably a shell ball, which preferably approaches the inner wall of the outer shaft. Thus it turns out that the inner shaft has a section with a smaller outer diameter than the inner diameter of the outer shaft, so that the inner shaft can Tilt on the outer shaft like a ball joint. Also, the inner shaft is mounted on the outer shaft in a longitudinally movable manner, so that material contractions in the long rows of solar modules can be mitigated.
    [0011] This construction results in that the outer shaft is also mounted on the pulley stand and, finally, also the inner shaft, since the inner shaft only presses with the interposition of the outer shaft on the same pulley stand. Therefore, a separate pulley stand can be dispensed with also where decoupled tracking of adjacent solar modules is desired.
    [0012] In detail, in this sense, the pulley support stand used may be formed by a trough profile, in which two adjacent rollers are located between the trough profile wings, forming between them a concavity open at the top and delimited by the surfaces below. external rollers for the safe housing against losses of the transmission shaft. If necessary, the trough profile wings, between the two rollers, can have a notch, so that the drive shaft does not rest on the trough profile wings.
    [0013] In a specific configuration, the shell element can also be arranged for a fixed connection in terms of the rotation of the inner shaft and the outer shaft, the shell having one or more dragging elements, preferably space-delimited elevations, which fit into counter-elements on the inner lining of the outer shaft, eg cavities, or otherwise cooperating therewith.
    [0014] As an alternative, it may be provided that the shell element is housed free of rotation in the outer shaft, that is, a rotation between the outer shaft and the inner shaft is not impeded by resistances that exceed the friction of normal material.
    [0015] For the connection of the two-part transmission shaft with the adjacent solar modules, they can be provided with some advantage at their free ends, connection plates that can be rigidly connected with the primary mirrors or photovoltaic elements, or their casing boxes.
    [0016] Furthermore, with particular advantage, the arrangement of the rollers in the trough profile can be selected so that the rollers are arranged at the same height and are rollers of the same type, therefore of the same material and of the same size. The distance of the rollers is selected so small that the drive shaft cannot fall between the rollers, but so large that no rollers do not touch.
    [0017] Preferably, the axes of rotation of rollers and drive shaft form an equilateral triangle with each other, with the axis of rotation of the drive shaft as the top vertex. The outer perimeter of the rollers can also be selected at least approximately corresponding to the outer perimeter of the outer shaft.
    [0018] Furthermore, the outer contour of the rollers in the axial direction can be selected convexly, so that the rollers are more or less barrel-shaped. For this reason, also in the case of an inclined position of the outer shaft with respect to the pulley support stand, a secure support of the same is guaranteed.
    [0019] In a preferred configuration, the outer tube has an additional intermediate tube, which is inserted into the inner tube and which, in case necessary, it is fixed in it, for example it is screwed. Inside the intermediate tube a housing is provided for the shell element, in which it is mounted in a longitudinally displaceable manner and / or in a rotationally mobile manner. The intermediate tube can preferably be made of plastic.
    [0020] The invention described above is explained in detail below by means of an exemplary embodiment.
    [0021] Show
    [0022] FIG. 1 shows a bearing for a solar module according to the state of the art with two adjacent, separate pulley support stands in a perspective representation, as well as
    [0023] FIG. 2 shows a bearing according to the present invention with a pulley stand and a two-part drive shaft in perspective representation.
    [0024] Figure 1 shows a bearing 1 in a form known from the state of the art. In order to allow the support of adjacent solar modules, for example primary mirrors or photovoltaic elements, two separate pulley stands 2 are used, which in each case independently carry the incoming drive shafts 8 on, in each case, two rollers 4. The primary mirrors connected through connecting plates 10 with the transmission shafts 8 can follow the height of the sun in this sense, decoupled from each other. Instead, this requires a special, wider construction, since, in the case of a fixed drive shaft, between two solar modules only a pulley support stand would be needed.
    [0025] On the contrary, Figure 2 shows a solution according to the Invention, which only provides a pulley support stand 2. This consists of a trough profile 3 with two protruding wings 6, between which two adjacent rollers 4 are inserted. In the area between the rollers 4, the wings 6 have, on both sides, a notch 7, to avoid contact between the transmission shaft 8 and the trough profile 3 of the pulley stand 2. In the concavity held by the two rollers 4 is placed a transmission shaft 8, which is formed in two parts. A first part, located on the outside, represents an external shaft 9, which at its free end allows a connection plate 10 for connection with the primary mirror located there. The tubular outer shaft 9 ends shortly after the pulley-bearing stand 2 and an inner shaft 11 is inserted inside the tubular outer shaft 9, which has a terminal shell element 12 and, at the opposite end, also a connecting plate 13. The shell element 12 approaches in this sense an intermediate tube inserted in the outer shaft, an intermediate tube that allows a shell housing for longitudinally movable, tilting and / or free fastening as regards the rotation of the shell element 12. With This is done a decoupling between the inner shaft and the outer shaft. In this way, a variation in the length of the connection between the adjacent solar modules can be compensated, as well as a different monitoring.
    [0026] Therefore, a bearing is described for the rotationally mobile support of solar modules, preferably primary mirrors or photovoltaic elements, in a solar power station, which represents a flexible but, nevertheless, simple solution for supporting modules. adjacent independent lots. For this, it is planned to form an external axis as tubes and to mount an internal axis in it through a shell element terminal, so that it is housed in the outer shaft in a longitudinally movable and tiltable manner, as well as, if necessary, freely in terms of rotation. To do this, only one pulley stand is necessary, even when two uncoupled drive shafts are mounted.
