VE RSTELLE I N RI CHTU NG FOR SOLARMODU LE

The present invention relates to a pivotable holding, supporting and / or adjusting device for solar modules with the features of independent claim 1.

In many cases, pivotable support devices for solar modules can be provided to carry the solar modules from east to west with the course of the sun in order to align the solar modules in the course of the day always in a suitable manner with respect to the sun. The solar modules are arranged on a pivot axis, which pivot axis is fixed at a certain distance from the ground on posts. The pivot axis can be pivoted via an actuator in a suitable manner. Such systems are often referred to as solar tracking systems. In solar tracking systems, a certain number of solar modules arranged in a row on a pivot axis are usually tracked to the changing position of the sun. For this purpose uniaxial and horizontally arranged systems are used in many cases. Typically, a single actuator may be provided to pivot the entire array of solar modules. The actuator is usually arranged in the middle of the row of solar modules. For example, the distance between the solar modules positioned closest to the actuator and the solar modules located at the end of a row may be up to 40 meters, in some cases even more.

Solar tracking systems are already known which allow a pivot axis for pivoting the solar modules about a certain pivot angle. Such a known system is shown in FIG. This is how the schematic shows

2 shows a solar tracking system 50 'with a pivotable device 4 for a certain number of solar modules 6 according to the prior art. The solar modules 6 are mounted on a pivot axis 8, which is arranged on a plurality of posts 10 and by means of which the solar modules 6 with respect to the horizontal

can be pivoted. For pivoting the pivot axis 8 and the

Solar modules 6, an actuator 12 is present. The actuator 12 is usually at one

Post 10 in the middle of a row 14 (see Fig. 1) arranged by solar modules 6. According to FIG. 2, the pivot axis 8 is pivoted by the angle α with respect to the horizontal into a position V deviating from the horizontal position. Since the solar modules 6 in the System 50 'are arranged on the pivot axis 8, the center of gravity S of the solar modules 6 is the height b above the center Z of the pivot axis 8. This results in a distance a of the center of gravity S from the center Z of the pivot axis 8. From the weight F of pivoted solar modules 6 and the distance a of the

Center of gravity S from the center Z of the pivot axis 8 may result in a moment M2, which acts on the construction of the pivot axis 8. The effect of the moment M2 on the pivot axis 8 of a side section of the row 14 is shown in FIG. 3 shows a schematic sectional illustration of a row 14 of solar modules 6. In this case, due to the elasticity of the pivot axis 8, in each case between the solar module 6a positioned closest to the actuator 12 of the pivot axis 8 and that positioned at the end 14 "of the row 14 Solar module 6b a rotation with respect to the pivot axis 8 by the angle ß. By this rotation results in a

Deterioration of the trackability of the solar modules 6 at a pivoting of the pivot axis 8. In addition, the actuator 12 of the pivot axis 8 undergoes an additional, for the time of pivoting ongoing burden due to the moment M2, which is held by the pivot axis 8 and the actuator 12 and must be overcome in an adjustment of the pivot axis 8.

In view of the state of the art, a primary object of the invention can be seen to develop a pivotable device for solar modules, which at least partially overcomes the above-mentioned disadvantages of the prior art, wherein the pivot axis or the actuator of the pivotable device in a relation to the Horizontal position pivoted position relieved and pivoting of the arranged on the pivot axis of solar modules is facilitated by means of the actuator. The above object is achieved by a pivotable holding, support and / or

Adjustment device for solar modules solved, comprising the features of claim 1. Further preferred embodiments are described by the dependent claims.

The invention relates to a pivotable holding, supporting and / or adjusting device for solar modules, which is also referred to in simplified form below as a device for solar modules or as a pivotable device for solar modules.

Due to the tension of the at least one spring element, a spring force can result, by which an active lever is formed on the pivot axis. In this way, a moment can be transmitted to the pivot axis by the spring force and the active lever, which can compensate for the moment at least approximately, in particular by the weight of the arranged on the pivot axis

In addition, it may be provided that the at least one cable element is coupled to the pivot axis in such a way that the at least one spring element has at least a low tension in a position of the pivot axis pivoted relative to the horizontal position. By the tension of at least one

Spring element may result in a stabilization of the pivotable holding, supporting and / or adjusting device or the pivot axis. Furthermore, it can be provided that the at least one damping module for vibration damping of

Pivot axis in the region of a first end is pivotally coupled to the pivot axis, and is arranged in the region of a second end in the region of the at least one spring element.

The compensating device or the mounting unit may further comprise sliding bearings, via which the compensating device or the mounting unit can be supported on the pivot axis. Thus, the mounting unit can be an example V comprise shaped frame which is equipped with a first frame part and with a second frame part, which converge in the region of a frame tip or are connected in the region of this frame tip. In particular, have themselves

Embodiments of the V-shaped frame proved to be advantageous, in which the open frame area to the side. Preferably, the plain bearings are in one

End region of the first frame part arranged and received by storage forks. The mounting unit can also be aligned with the pivot axis via the slide bearings. In the area of the storage forks, a lever element can furthermore be arranged, which is non-rotatably coupled to the pivot axis and optionally pivotally connected to the frame. The at least one spring element can be arranged pivotably on the second frame part. Between the at least one spring element and the lever element, the at least one cable element may extend, which

For further stabilization of the pivotable holding, support and / or

Adjustment device or the pivot axis, the at least one damping module is preferably arranged pivotably between the connection region of the spring elements to the frame and the lever element. This results in a preferably triangular configuration of the compensation device or the assembly unit, which receives an additional stabilization by the damping module. By the

Triangular shape of the compensation device or the mounting unit is the

Swiveling movement of the pivotable holding, supporting and / or adjusting device is not restricted. By means of such a described arrangement of the damping module, vibrations due to the occurrence of wind, for example, can be absorbed at the pivot axis or at the solar modules, resulting in a stable and stable system.

In a further embodiment of the pivotable holding, supporting and / or adjusting device according to the invention, the pivot axis by means of a

Fixing device may be arranged in the form of a hinge bearing on the at least one post. Preferably, it can be provided that the pivot axis and the at least one post at an horizontal position of the pivot axis form an angle φ of preferably 90 °. The pivot axis can in this case by means of

The compensation device can be coupled to the pivot axis and pivotally connected to the at least one post. With an inclination of the pivot axis by an angle φ 'relative to the at least one post, the compensating device can maintain an at least approximately constant angle ω by said coupling with the pivot axis and by the pivotable coupling with the at least one post, which preferably still approaches at least approximately 90 °.

The hinge bearing may comprise a spherical housing within which a ball element is disposed. The spherical housing may consist of a lower shell and an upper shell. Within the spherical housing can a

Ball element may be arranged, which consists of a first ball half and a second ball half. The pivot axis can be stored between the first half of the ball and the second half of the ball element. In particular, the outer upper radius of the joint bearing can be kept relatively small due to a thin-walled design of the upper shell. Such a configuration is particularly advantageous in terms of which the center of gravity of the structures can lie at a low height above the center of the pivot axis. From the weight of the pivoted solar modules and the small distance of the center of gravity from the center of the

Pivot axis can result in a much lower torque, as is known in the art.

In a preferred embodiment, the joint bearing is a dry plain bearing. Therefore, it can be provided in particular that the materials of the ball halves and the lower shell are selected such that a

Pairing may occur, which is designed for a dry run suitable. Since a stable complete seal such storage, which must be able to work properly under all environmental conditions such as rain, wind or sand storms, can only be produced in a serious way, it is advantageous if registered in the hinge bearing impurities as soon as possible from the

Spherical bearing can be removed. Therefore, it can be provided that the lower shell of the spherical housing is divided on the contact side to the second ball half in grooves and support areas. In addition, the lower shell of the spherical housing may have a funnel bottom, which leads to at least one opening in the lower shell. Through the grooves and support areas, as well as the hopper floor and at least one opening dirt particles and water can be discharged from the joint stock. As a result, a functional reliability and only minimal wear of the joint bearing can be ensured.

At least one compensating device of the pivotable holding, supporting and / or adjusting device for solar modules described above can be used in particular for a solar tracking system which provides a plurality of solar modules arranged in a row. The plurality of solar modules can be arranged on a common pivot axis, which pivot axis can be supported or supported by means of several posts. The at least one provided compensating device of the pivotable holding, supporting and / or adjusting device for solar modules can be provided on at least one post at at least one end of the row of solar modules arranged on the pivot axis. Furthermore, a plurality of compensation devices of the pivotable holding, supporting and / or adjusting device can be provided on posts of a series of solar modules arranged on a pivot axis.

For identical or equivalent elements of the invention, identical reference numerals are used. Furthermore, for the sake of clarity, only reference symbols are shown in the individual figures, which are required for the description of the respective figure. The illustrated embodiments are only examples of how the device according to the invention can be designed and do not represent a final limitation.

FIG. 1 shows a uniaxial, horizontally arranged solar tracking system 50. The solar tracking system 50 comprises a certain number of solar modules 6, which are arranged on a commonly common pivot axis 8 in a row 14. The row 14 of solar modules 6 or the pivot axis 8 is seen along the pivot axis 8 relative to a horizontal position of the solar modules 6 and the pivot axis 8 pivotally. The pivot axis 8 of the pivotable holding, supporting and / or adjusting device 2 is arranged on regularly spaced posts 10 in an intended height. By means of a fastening device 34 (cf., for example, Fig. 4), the pivot axis 8 is mounted on the respective post 10. By means of an actuator 12, the pivot axis 8 can be brought along the pivot axis 8 in a position pivoted relative to the horizontal position (see, for example, Fig. 6). The actuator 12 is usually positioned in the center of the solar modules 6 arranged in the row 14. In the area of the actuator 12, a region 14 'which is free of solar modules 6 can be provided. By means of the actuator 12, the solar modules 6 can be carried from east to west with the course of the sun. The distance D between the solar module 6a positioned closest to the actuator 12 of the pivot axis 8 and the solar module 6b positioned at the end 14 "of the row 14 may be up to 40 meters or more.

In Fig. 4, a pivotable holding, supporting and / or adjusting device 2 according to the invention for solar modules 6 is shown. A compensation device 16 of the pivotable holding, supporting and / or adjusting device 2 is usually provided in each case on a post 10 in the region of the ends 14 "of the row 14, in order to obtain an ideal weight compensation of the solar modules 6 or a rotation of the pivot axis 8, which is usually most pronounced in the region of the ends 14 "of the row 14, counteract. Furthermore, an arrangement of a plurality of balancing devices 16 on a plurality of posts 10 of the solar tracking system 50 conceivable.

According to the first embodiment of FIG. 4, the pivotable holding, supporting and / or adjusting device 2 comprises a compensation device 16 or 16a. The

Compensating means 16a in this case has a V-shaped lever element 18, which is mounted non-rotatably on the pivot axis 8. In addition to a V-shape of the lever member 18 and an embodiment of which, for example, in a U-shape or an angular shape is possible. The pivot axis 8 may be, for example, a round, square or polygonal tube. The lever member 18 is also perpendicular to the horizontal position W of the pivot axis 8 also arranged horizontally

Solar modules 6 rotatably fixed to the pivot axis 8 so that it is aligned parallel to the post 10 and vertically in the direction of the bottom 28. The illustrated post 10 is a post 10 arranged in the region of the end 14 "of the row 14. As a further component of the compensating device 16a, a connecting element 20 is attached in a rotationally fixed manner to the post 10 in a ground-level position A connection element 30 arranged at the lower end of the lever element 18 and at a connection point 32 provided on the articulation element 20 can each pivotably fasten a connection element 24 or 26, between which attachment elements 24 and 26 at least one spring element 22 can be introduced 4, two spring elements 22 are provided Depending on the design of the compensation device 16a, one is also a

Arrangement of a plurality of spring elements 22 conceivable. Here, between the center Z of the pivot axis 8 and the connection point 30 of the connecting element 26 to the lever member 18, a distance LH, between the connection point 30 of the connecting element 26 to the lever member 18 and the connection point 32 of the connecting element 24 to the hinge element 20, a distance LF , In the illustrated horizontal position W of the pivot axis 8 and the solar modules 6 according to FIG. 4, the spring elements 22 are in the unloaded position, so that the spring elements 22 have no or at least almost no bias. In Fig. 5 is another view of the invention pivotable holding,

Support and / or adjusting device 2 for solar modules 6 shown. This shows in particular the parallel arrangement of the components of the compensation device 16a, such as the lever member 18, the coupling element 20 and the spring elements 22, with respect to the post 10, or the rectangular arrangement of the lever member 18 with respect to the pivot axis 8 and the solar modules 6. The compensation device 16a is in turn attached to the outermost post 10 in the region of the end 14 "of the row 14. The distance P of the lever element 18 from the post 10 usually results from the structural design of the spring elements 22 and des

Connecting element 20, however, at least such a distance P is provided so that upon thermal expansion of the pivot axis 8 no collision of the spring elements with the post 10 may arise.

By Fig. 6, the effect of the balancer 16a at a

Pivoting the pivot axis 8 of the pivotable holding, support and / or

Adjusting device 2 represented by an intended angle γ. By the

Pivoting the pivot axis 8, the rotatably mounted on the pivot axis 8 lever member 18 of the balancer 16 a is also pivoted by the angle γ relative to the vertical. The distance of the attachment point 30 of the lever element 18 from the center Z of the pivot axis 8 comprises, as already described in connection with FIG. 4, a length LH. Due to the pivoting of the lever member 18, the spring elements 22 are tensioned by the resulting stroke H. As a result, the distance LF between the connection point 30 of the connection element 26 to the lever element 18 and the connection point 32 of the connection element 24 to the coupling element 20 increases by the stroke H, so that the clamping length of the spring elements 22 increases and the spring elements 22 a

Have voltage, as shown by the distance LF + H is shown. From the resulting tension of the spring elements 22, a spring force FK can emerge, whereby an active lever is formed on the pivot axis 8. One of the spring force FK and the active lever can result in a counter-moment M1, which is opposite to the

Moments M2 (see Figures 2 and 3) acts. Preferably, an interpretation of the lever member 18 and the spring elements 22 such that the moment M2 and the counter torque M1 compensate each other. In this way can by the

Compensation device 16a a more accurate tracking of the solar modules 6 and a relief of the pivot axis 8 are possible. In addition, the tension of the spring elements 22 can be used to facilitate the pivoting back of the pivot axis 8 in the horizontal position, since this is a lower energy consumption for

Pivoting the pivot axis 8 is required.

7 shows a further embodiment of the pivotable holding, supporting and / or adjusting device 2 with a compensation device 16b, which has a damping module 36. For connection of the damping module 36, the lever element 18 has a planar connection projection 38, which at least is arranged approximately at right angles to the lever element 18. In addition, the

Connection projection 38 at least approximately parallel to the solar modules 6 arranged. Furthermore, the coupling element 20 has a connection projection 40. Between the attachment projection 38 and the attachment projection 40, the damping module 36 can be pivotably arranged on the attachment projection 38 and the attachment projection 40. The damping module 36 may be

for example, to act a hydraulic damping cylinder. By the

Damping module 36, a stabilization of the pivot axis 8 and the solar modules 6 are effected. Especially with respect to the horizontal position

pivoted position V of the pivot axis 8 and the solar modules 6 is the

pivotable holding, supporting and / or adjusting device for solar modules 2 and the solar tracking system 50 often strongly influenced by wind, whereby vibrations with respect to the pivot axis 8 can arise and therefore an additional load on the pivot axis 8 is caused. By means of the

Damping module 36, the wind induced load of the pivot axis 8 can be at least partially compensated or damped.

FIG. 8 describes a further embodiment of the compensating device 16c for the pivot axis 8 or for the solar modules 6 of a pivotable holding, supporting and / or adjusting device 2. Here, the compensation device 16c comprises a combination of a spring element 22 and a cable element 42. According to FIG. 8, the pivot axis 8 or the solar modules 6 are in horizontal position W, so that the lever element 18 is aligned parallel to the post 10 or vertically. The post 10 is again a post 10 positioned in the region of the end 14 "of the row 14. Compared with the embodiment of the compensating device 16a or 16b according to FIGS. 4 to 7, the spring element 22 is in the case of FIG

Compensating means 16 c arranged on the opposite side of the post 10 and arranged at a connection point 34 ^* in the region of the fastening device 34 of the pivot axis 8 at the upper end of the post 10. In horizontal position of the pivot axis 8 and the solar modules 6, the spring element 22 has no or almost no bias, as indicated by the designation LF '. At the connection point 30 of the lever member 18, the cable 42 is attached to a first end 42 '. In horizontal position W of the pivot axis 8, a deflection device 44 is arranged at a short distance from the lever element 18 on the post 10, which deflection device consists of two deflection rollers 44 '(see FIG. The two pulleys 44 'of

Deflection device 44 are arranged side by side on the post 10, that the cable 42 is deflected at a deflection of the lever member 18 due to a pivoting of the pivot axis 8 in each case by one of the deflection rollers 44 '. In the region of the lower end of the post 10 further deflecting devices 46 and 48 are arranged opposite each other on two sides of the post 10, which

Deflection devices 46 and 48 are also formed by pulleys. in the

Area of the deflection devices 46 and 48, an unillustrated breakthrough in the post 10 is introduced. The attached to the lever member 18 cable 42 is guided by the deflection device 44 and is guided by the deflection devices 46 and 48 through the opening in the post 10. Furthermore, the cable 42 is fastened with a second end 42 "to the lower end 22 'of the spring element 22. The steering or connection of the cable 42 to the lever element 18 and the spring element 22 can also provide a more accurate tracking compared to the prior art the solar modules 6 and a relief of the pivot axis 8. In addition, in this embodiment, the compensation device 16c, the voltage of

Spring element 22 can be used to facilitate the pivoting back of the pivot axis 8 in the horizontal position, since in this case a lower energy consumption for

Pivoting the pivot axis 8 is required. Advantageously, in this embodiment of the compensation device 16c, a possible attachment of a longer spring element 22 in comparison to the compensation device 16a has an effect. A longer spring element 22 can result, in particular, from the connection of the spring element 22 at the connection point 34 ^* at the upper end of the post 10 and an arrangement of the deflection devices 46 and 48 or the opening in the area near the bottom of the post 10.

In Fig. 9 is a pivotable holding, supporting and / or adjusting device 2 for solar modules 6 according to the embodiment of FIG. 8 with respect to the

Horizontal position pivoted pivot axis 8 shown. In the illustration according to FIG. 9, the guidance of the cable 42 of the compensation device 16c is clearly recognizable at a position V of the pivot axis 8 or the lever element 18 which is pivoted relative to the horizontal position. As already mentioned, the deflection rollers 44 'of the deflection device 44 are arranged next to one another in such a way that, depending on a pivoting of the lever element 18, a steering of the cable 42 is made possible by one of the deflection rollers 44'. Due to the pivoting of the

Lever element 18 resulting stroke H 'and thereby attracted rope 42 is a voltage of the spring element 22 so that a voltage of the spring element 22 results, which is illustrated by the designation LF' + H '. By the detailed view of the pivotable holding, supporting and / or adjusting device 2 of FIG. 10 is again the effect of the compensation device 16 c at a relative to the horizontal position pivoted position V of

Swivel axis 8 explained in detail. The pivot axis 8 and the lever member 18 is inclined in this case by the angle γ relative to the vertical. Corresponding to the distance AR of the deflection device 44 to the center Z of the pivot axis 8, the angle Ω can be formed when the pivot axis or the lever element 18 is pivoted by the angle γ between the lever element 18 and the course of the cable 42. By this embodiment of the compensating device 16c, a faster construction of the action lever WH is possible. By means of the compensation device 16c, a counter-torque M1 can be formed, wherein by the Ausgestaltungsweise the

Compensating means 16 c, the counter-torque M1 by the stroke H 'of the spring element 22 may increase even faster than in the Ausgestaltungsweise the

Compensation device 16a, as indicated by a theoretical traction line 52 (see Fig. 9) of a spring element. As with the compensation device 16a, the lever element 18, the cable 42 and the spring elements 22 can be designed in the compensation device 16c such that the moment M2 (see FIGS. 6, 10) compensate each other.

In Fig. 1 1, a further embodiment of an inventive

Compensating means 16 or 16d for the pivot axis 8 and the solar modules 6 a pivotable holding, supporting and / or adjusting device 2 described. The

Compensating device 16d is composed of a mounting unit 54. About foundation connecting elements 60, the mounting unit 54 can be attached to a, for example, from two mutually arranged at a certain angle post 10 post assembly 10 '. In particular, this post are 10, which can be anchored with a Schraubfundamentierung in the ground. The foundation connection elements 60 can each be designed to be suitable for the posts 10 intended for use. In order to be able to adapt the foundation connection elements 60 to the respectively used post arrangement 10 ', the foundation connection element 60 can also be designed to be adjustable. Thus, it can be provided that the foundation connection elements 60 are each adaptable to different alignment angles of the post arrangement 10 ', thereby also

Assembly tolerances of the post assembly 10 'to compensate. By means of a fastening device 34 on the post assembly 10 ', a pivot axis 8 relative to the horizontal pivotally mounted on the post assembly 10' are stored. The assembly unit 54 in this case comprises an example V-shaped frame 56 with a first frame part 56 'and a second frame part 56 "which converge in the region of a frame tip 56"' or are connected in the region of this frame tip 56 "' The frame 56 is equipped with bearing forks 57. Sliding bearings 58 are accommodated in the bearing forks 57, whereby the bearing forks 57 can be supported on the pivot axis 8. The mounting unit 54 can also be aligned with the pivot axis 8 via the sliding bearings 58. In the region of the storage forks 57, a lever element 18 is furthermore arranged, which is non-rotatably coupled to the pivot axis 8 and optionally pivotally connected to the frame 56. Two spring elements 22 are pivotably arranged on the second frame part 56 ". Preferably, an attachment element 23 for the spring elements 22 is located in an end region of the second frame part 56 ", so that they extend from the end region of the second frame part 56" in the direction of the tip 56 "'of the frame 56. Between the spring elements 22 and the lever element 18, a cable element 42 extends, which is preferably deflected in the region of the frame tip 56 '' and in a region between the frame tip 56 '' and the bearing yokes 57 or of the lever element 18 via deflecting devices 44 and 46 consisting of deflection rollers consist of two pulleys, so that a deflection of the cable element 42 regardless of the direction of the

Pivoting the pivot axis 8 is possible.

In a horizontal position W of the pivot axis 8 and from on the

Pivot axis arranged 8 solar modules 6, the lever member 18 is in such a starting position A (see Fig. 12A), that the cable element 42 is not deflected and causes no or at least almost no tension of the spring elements 22. Is the pivot axis 8 in a relation to the horizontal position of the pivot axis 8 and the solar modules 6 pivoted position V, that is

Lever element 18 with respect to the above-mentioned starting position A (position B, see Fig. 12B) deflected so that the cable element 42 also moves, whereby at least a low voltage of the spring elements 22 is effected. The tension of the spring elements 22 results in a stabilization or relief of the pivotable holding, supporting and / or adjusting device 2 and the pivot axis 8. For further stabilization of the pivotable holding, supporting and / or adjusting device 2 and the pivot axis 8 or for compensation possibly occurring shrinkages on the pivot axis 8 is preferably between the connection region of

Spring elements 22 to the fastener 23 and the lever member 18 a Attenuation module 36 pivotally mounted. This results in a preferably triangular configuration of the mounting unit 54, which by the

Damping element 36 receives additional stabilization. By means of a described arrangement of the damping module 36, vibrations due to the formation of wind, for example, can be damped at the pivot axis 8 or at the solar modules 6, resulting in a system which is less or hardly susceptible to vibrations and thus relatively stable.

To facilitate the installation of the compensation device 16d individual components of the mounting unit 54 can be pre-assembled. Thus, for example, a pre-assembly of the spring elements 22, the damping module 36, the deflection devices 44 and 46, the traction cable 42 and the lever member 18 on the frame 56 are possible, whereby they can be held in an exactly predetermined position to each other.

Figures 12A and 12B show a view along the pivot axis 8 view of pivotal holding, supporting and / or adjusting devices 2, which are each equipped with compensation devices 16d according to the embodiment of FIG. 1 1 are equipped. FIG. 12A shows the pivotable holding, supporting and / or adjusting device 2 with a pivot axis 8 located in horizontal position W or with itself in FIG

Horizontal position W located solar modules 6. This is the

Lever element 18 in the starting position A, so that the spring elements 22 of the mounting unit 54 are in an untensioned state, since the traction cable 42 is not deflected in this position A. Is the pivot axis 8 or the solar modules 6 are compared to the horizontal position of the pivot axis 8 and the solar modules 6 pivoted by an angle α, as shown for example in Fig. 12B, the

Lever member 18 is also pivoted by the angle α, so that the lever member 18 is in a relation to the starting position A deflected position B, and thereby moves the pull cable 42, whereby the spring elements 22 are tensioned. The damping module 36 is in this case also moved. Both in the horizontal position W and in the relation to the horizontal position rotated position V of

Swivel axis 8 and the solar modules 6 can be done by means of the damping module 36, a compensation or damping of vibrations, resulting in a very stable at any time system.

FIGS. 13A and 13B show a further embodiment of a

to see pivotable support, support and / or adjusting device 2 according to the invention. FIGS. 13A and 13B each show a lateral view of the pivotable holding, Supporting and / or adjusting device 2. Here, the pivot axis 8 by means of a fastening device 34 'on the post 10 and a post assembly 10' is mounted. In the horizontal position W of the pivot axis 8, as shown in FIG. 13A, an angle φ of 90 ° is preferably included between the pivot axis 8 and the posts 10. Basically, a correct functioning of the

Fastening device 34 'also in a relation to the horizontal position

pivoted position V of the pivot axis 8 possible. At the post 10 and the pivot axis 8 is in a preferably minimum distance P 'continue to

Example, a compensation device 16 d mounted, as described for example already by the figures 1 1 and 12. In the area of the frame 56 is the

Compensating device 16 d pivotally attached to the post 10 via the foundation connection element 60. Furthermore, the frame 56 is connected via the bearing forks 57 and the sliding bearing 58 on the pivot axis 8, so that between the pivot axis 8 and the mounting unit 54, an angle ω results, which preferably in the horizontal position W of the pivot axis 8 an amount of 90 also °. As already mentioned in connection with FIGS. 1 and 12, the lifting element 18 is secured against rotation on the pivot axis 8.

In particular, through the Fig. 13B is visible that the fastening device 34 'has a pivot bearing 69 which surrounds the pivot axis 8. By using such a spherical bearing 69 for the mounting of the pivot axis 8 is not only a pivoting of the pivot axis 8 and the solar modules 6 along the pivot axis 8 possible (positions W, V), as shown for example by FIG. 12B, but The pivot axis 8 or the solar modules 6 can also be inclined by the angle φ 'with respect to the posts 10 (see reference numeral N). The angle φ 'may thus have, for example, an amount of 91 ° to 140 °. By the swiveling

Storage of the frame 56 by means of the foundation connecting element 60 to the post 10, the frame 56 with the respective components corresponding to the inclination N of the pivot axis 8 by the angle φ 'pivot. However, the angle ω between the frame 56 and the pivot axis 8 remains unchanged. The compensating device 16d is thus coupled to the pivot axis 8 and the post 10 in such a way that the compensating device 16d and the pivot axis 8 always have an inclination N of the pivot axis 8 at an arbitrary angle φ 'with respect to the posts 10 both at horizontal position W of the pivot axis 8 include a constant angle ω of 90 °. The distance P "between the posts 10 and the

Compensating device 16d increases compared to the horizontal position W of Swivel axis 8. As a result, all rotary and swivel axes within the

Mounting unit 54 always formed axially parallel. In addition, beyond the desired restoring force of the spring elements 22, no unwanted twists occur. Due to the additional inclination possibility of the pivot axis 8 and the solar modules 6 with respect to the post 10, the solar modules 6 can be even more suitable with respect to the

Align the sun's position.

14 shows a fastening device 34 'or a spherical plain bearing 69, as may be used, for example, in the case of the pivotable holding, supporting and / or adjusting device 2 according to FIGS. 13A and 13B. Furthermore, the use of such a fastening device 34 'or such a hinge bearing 69 in

Connection with a pivotable holding, supporting and / or adjusting device 2 according to one of the embodiments of Figures 4 to 12 conceivable. In particular, in FIG. 14, the connection point or the mounting for the pivot axis 8 is visible. The fastening device 34 'can in this case be arranged as desired on posts 10 or a post arrangement 10'. For this purpose, the fastening device 34 'has a holding fork element 62, which is designed, for example, as a sheet-metal forming part. The retaining fork element 62 can be fastened to the post 10 or the post assembly 10 'via a screw connection 70, and positively receives a lower shell 64. Together with a preferably thin-walled upper shell 66, which is fixed via a screw 72 to the support fork member 62, a spherical housing 67 is formed. A divisible ball element 68 consisting of a first ball half 68 'and a second ball half 68 "can be rotatably supported in the spherical housing 67. The pivot axis 8 can be positioned between the first and the second ball half 68' and 68". Through the interaction of the spherical housing 67 and the ball member 68, the spherical bearing 69 can be formed for the pivot axis 8. Such a spherical design allows for

Swivel axis 8 tolerance compensation in all directions, which in particular for the installation of the pivotable system provides a great deal of relief. Due to the split design of the joint bearing 69, the mounting of the pivotable holding, supporting and / or adjusting device 2 and the pivot axis 8 to the post 10 is also facilitated. Thus, the pivot axis 8 can be inserted into the lower shell 64 "already fastened to the posts 10 via the retaining fork element 62 or into the second spherical half 68" The joint bearing 69 can then be closed by the first ball half 68 'and the upper shell 66 Components of the

Spherical bearing 69 enclosed by the spherical housing 67 and in particular are covered by the thin-walled upper shell 66, these are also available

Protected from sunlight, which increases the life of the components and a long-term outdoor use is possible. This is especially true for

Ingredients, which are made of plastic. FIG. 15A once again shows the fastening device 34 'according to FIG. 14 along the pivot axis 8. This clearly shows how the

Holding fork element 62 receives the lower shell 64 in a form-fitting manner. In the direction of the pivot axis 8, the outer upper radius RL of the joint bearing 69 can be seen, which can be kept relatively small due to the thin-walled design of the upper shell 66. Such a configuration is particularly advantageous in terms of the fact that the center of gravity S of the structures can lie at a low height above the center Z of the pivot axis 8. From the weight F of the pivoted solar modules 6 and the small distance of the center of gravity S from the center Z of the pivot axis 8 can result in a much lower torque, as is known from the prior art.

FIG. 15B likewise shows an advantageous embodiment of the joint bearing 69. In particular, the small construction height of the upper shell 66 of the spherical housing 67 is clearly visible again through FIG. 15B. For example, the upper shell 66 may be made of a deep-drawing steel. Preferably, the hinge bearing 69 is a dry plain bearing. Therefore, it can be provided that the materials of the ball halves 68 'and 68 "with the ball surface KO and the

Lower shell 64 are selected such that a sliding pairing can occur, which is designed to be suitable for dry running. Since a secure complete seal such storage, which must be able to work properly under all environmental conditions such as rain, wind or sandstorms, only in a difficult or difficult to produce, it is advantageous if registered in the hinge bearing 69 impurities as soon as possible by itself can be removed again.

Therefore, the lower shell 64 here on the contact side to the second

Ball half 68 "no continuous contact surface, but is divided into preferably a plurality of grooves R and support portions T. The number of grooves R and the

Support areas T can be selected depending on the size of the pivot bearing 69. The grooves R can lead into a funnel bottom TB of the lower shell 64. In the area of the funnel bottom TB further two openings O are arranged in the lower shell 64. About the hopper floor TB possibly existing dirt particles and water are the two openings O out, so that the dirt particles and the water can be discharged from the joint bearing 69. It may already be sufficient to design the lower shell 64 in such a way. By the described design of the lower shell 64 dirt particles and water, which have penetrated into the joint bearing 69, in a simple, fast and safe way back from the

Spherical bearing 69 are discharged. As a result, a functional reliability and minimum wear of the joint bearing 69 can be ensured.

The invention has been described with reference to a preferred embodiment. However, it will be apparent to those skilled in the art that modifications or changes may be made to the invention without departing from the scope of the following claims.
