Description

The invention relates to a supporting structure for solar modules according to the preamble of claim 1.

Such a support structure is from the DE 20 2012 103 108 U1 known. This supporting structure for solar modules comprises an arrangement of mounted on a substrate post. At each post, a carrier unit is pivotally mounted, wherein the carrier unit has two transverse bars carrying struts, whose ends facing away from the cross member are mounted in a pivot bearing. The cross member is slidably mounted by means of guide means on the post. On the cross member receiving means for the storage of solar modules are provided. By setting and fixing a pivot position of the carrier unit, the inclination of the solar modules is specified.

An advantage of this support structure is that the struts with the cross member form a universal, suitable for different applications unit that can be quickly and accurately adjusted by pivoting the pivot bearing in their inclination. This results in a simple and reliable Neigungsverstellmöglichkeit mounted on these modules solar modules. Since the same components are used in unaltered shape and arrangement for the tilt-adjustable unit with the struts and the cross member always results in a significant rationalization effect on the production of their construction.

In this support structure, two longitudinal beams are mounted on the cross beams, the longitudinal axes of which extend expediently perpendicular to the longitudinal axes of the mutually parallel cross members. The solar modules are then mounted on these side rails.

Thus, in this support structure, a one-sided arrangement of adjacent solar modules is realized.

The invention has the object of developing a support structure of the type mentioned in such a way that on this a multi-sided arrangement of solar modules can be stored.

To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

The support structure according to the invention for solar modules comprises an arrangement of mounted on a substrate post. At each post a carrier unit is tilt-mounted, which has a cross member. On the cross beams, an upper and lower side member are mounted. Between the longitudinal members a running central longitudinal member is provided, which is mounted on the post. On opposite sides of the central longitudinal support receptacles are provided, in which edges of solar modules are inserted. On the longitudinal members fastening means are provided, by means of which only one solar module is attached to its underside.

A significant advantage of the support structure according to the invention is that a double-row arrangement of solar modules can be arranged on this, wherein the support structure has a compact, manufacturing technology favorable structure and in particular the assembly costs for the attachment of the solar modules can be kept low on the support structure.

The assembly costs for the attachment of the solar modules can be kept low in particular by the fact that the solar modules can be inserted with one of its edges in one of the receptacles of the center longitudinal member, whereby this edge is already secured in position on the support structure without any further fixing.

Therefore, each solar module needs to be definitively fixed only by fastening means on one of the longitudinal members in order to fix the solar module firmly to the support structure in a predetermined desired position permanently.

The solar modules can thus be attached to the supporting structure with little installation effort.

Another essential aspect of the invention is that each fastening means only one solar module is attached to a side rail, on the underside of the solar module.

The solar modules are thus fixed individually to the longitudinal members with the fastening means, so that each solar module can be individually aligned in its desired position, which can be done by moving the solar module in the receptacle of the central longitudinal member, and then the solar module by the fastener on the longitudinal member in the desired Target position can be attached. It is particularly advantageous that the positions of all solar modules can be selected individually and can be specified independently of the positions of the other solar modules. Preferably, the fastening means are fixed by means of screw on the solar modules. Another advantage of the invention is that with the fasteners an attachment to the bottom of each solar module takes place. The fastener does not have to embrace the edge of a solar module and thus can have a compact, structurally simple structure.

According to an advantageous embodiment of the invention, the receptacles of the central longitudinal support for the solar modules are U-shaped.

This design of the recordings has a high constructional effort on a high ease of installation, since the solar modules can be easily inserted with their edges in these U-shaped receptacles. Particularly advantageous are the solar modules with little play in the U-shaped recordings.

According to a first advantageous embodiment, the receptacles are formed by discrete receiving elements, which are fixed in predetermined positions on the central longitudinal member.

Since in this case only individual, discrete receiving elements are arranged distributed over the central longitudinal member, the recordings thus formed can be produced with a low use of material.

Particularly advantageously, the receiving elements are clamped onto the central longitudinal beams.

The receiving elements can thus be easily and quickly mounted on the central longitudinal beam.

According to a second advantageous embodiment, the recordings extend over the entire length of the central longitudinal member.

Particularly advantageously, the recordings are formed integrally with the central longitudinal beam.

The recordings thus form a ready-to-use unit with the center longitudinal member, which results in a particularly low installation effort.

According to a particularly expedient embodiment, each receptacle of the central longitudinal member has a lower leg, on which a solar module rests, and an upper leg, which rests on the top of the solar module, wherein the length of the lower leg is greater than the length of the upper leg.

This design of the U-shaped receptacles, the installation of the solar modules is further facilitated because the edges of the solar modules are first placed on the protruding part of the lower leg of the U-shaped receptacle, wherein then the solar module easily between the legs of the U-shaped Recording can be inserted.

According to an advantageous embodiment of the invention, the images are provided at an inclination angle on the central longitudinal member, wherein the inclination of the solar modules is determined on the support structure by this inclination angle.

This means that the inclination of the solar modules to the supporting structure is already predetermined by the fixation of the central longitudinal member to the post. The tilt-adjustable support units on the posts can then be suitably adapted to adapt the side members to this inclination adjustment, wherein it is particularly advantageous that tolerances in the positions of the side members can be compensated by the adjustable inclination of the individual carrier units.

Particularly advantageously, the support structure forms a modular system with different central longitudinal members, wherein the recordings are arranged at different angles of inclination at different center longitudinal members.

The support structure according to the invention thus forms a modular system in which the inclination of the solar modules on the support structure can be determined solely by the selection of a specific center longitudinal member.

According to a structurally advantageous embodiment of the central longitudinal beam is formed in the form of a hollow profile construction.

Advantageously, the central longitudinal beam is formed by a plurality of connecting elements connected in longitudinal direction adjoining hollow profiles, wherein the connecting elements are formed by profiles or tubes which extend in the hollow profiles.

With the hollow profiles connected via the connecting elements center longitudinal members can be provided in any length quickly and easily. The hollow profiles may have different lengths, therefore, the joints between two hollow sections at any point of the center longitudinal member, preferably in the areas between the individual posts, are located.

Particularly advantageously, a connecting element connecting two adjoining hollow profiles is firmly connected only to one of the hollow profiles.

As a result, changes in length or in general delays of the hollow profiles, which are caused by temperature fluctuations or the like, can be easily absorbed and compensated.

The elements of the supporting structure, in particular also the central longitudinal members and the longitudinal members, are advantageously made of metallic materials, in particular of aluminum extruded profiles.

According to a particularly cost-effective variant, the longitudinal members of the supporting structure can also be made of wood.

According to a particularly advantageous embodiment of the invention, each carrier unit has two transverse struts supporting struts, whose ends facing away from the cross member are mounted in a pivot bearing. The cross member is mounted by means of guide means tilt adjustable on the post.

According to a first advantageous embodiment, the guide means are designed such that with these continuously varying inclination angle of the solar modules can be specified.

Particularly advantageous is provided as a guide means in the cross member a slot and the post a guided in the slot pin.

According to an alternative, advantageous embodiment, the guide means are designed such that one or more discrete angles of inclination of the solar modules can be predetermined with them.

In particular, the guide means are designed such that a plurality of discrete angles of inclination of the solar modules can be predetermined with them. For this purpose, a series of discrete holes may be provided as guide means in the cross member. The post provided on the post can then optionally be inserted into one of these holes.

Alternatively, as a guide application specific a single hole is incorporated in the cross member whose position in the cross member defines the angle of inclination, and that on the post, a pin is provided which is inserted into the hole.

In this embodiment, adapted to the respective application, to specify the desired angle of inclination factory with an inclined tool at the installation of the support structure only a hole in a corresponding, the inclination angle corresponding target position incorporated.

A significant advantage of the support structure formed in this way is that in the carrier unit, the struts take up the main load of the weight forces acting from above, whereas the crossbeam thereof is largely relieved of this. It is essential that in a tilt adjustment essentially only the cross member by means of the guide means must perform a displacement movement, and that against the post. Since the cross member and the guide means, unlike the struts hardly have to absorb weight forces, a simple tilt adjustment is guaranteed.

The invention will be explained below with reference to the drawings. Show it:

The 1 and 2 schematically show a section of an embodiment of the support structure according to the invention 1 for solar modules 2 , The supporting structure 1 with the solar modules 2 forms a free-range plant. The supporting structure 1 comprises a row of posts arranged along a straight line 3 with vertical longitudinal axes in a subsoil 4 are anchored. Advantageously, the individual posts 3 arranged equidistantly. The single posts 3 are identical.

The supporting structure 1 of the 1 and 2 includes two posts 3 , being on the supporting structure 1 a total of six solar modules 2 are arranged in two superimposed rows. It shows 1 the complete assignment of the supporting structure 1 with all six while 2 the supporting structure 1 with only three solar modules fixed on it 2 shows. The supporting structure 1 Of course, a larger number of posts can also be used 3 and a correspondingly larger number of solar modules 2 ,

Like from the 1 and 2 Obviously, they are on the supporting structure 1 arranged solar modules 2 arranged in a plane inclined with respect to the horizontal plane, wherein the inclination angle is about 30 °. In a field installation are typically several such support structures 1 provided and each oriented to the south.

As in particular from 3 Obviously, is at every post 3 a carrier unit 5 swiveling and thus adjustable in inclination. The respectively identically designed carrier units 5 each comprise a cross member 6 and two struts attached to it 7a . 7b , On the crossbeams 6 become longitudinal beams 8a . 8b applied, whose longitudinal axes perpendicular to the longitudinal axes of the cross member 6 run. In the present case are on the cross member 6 two parallel side members 8a . 8b intended.

Like from the 1 to 3 can be seen, includes the support structure 1 a central longitudinal beam 9 whose longitudinal axis is parallel to the longitudinal axes of the longitudinal members 8a . 8b runs. Here is the center longitudinal beam 9 vertically and symmetrically between the upper longitudinal member 8a and the lower side member 8b arranged. The central longitudinal beam 9 is doing on the tops of each post 3 stored.

The supporting structure 1 is preferably made of metallic materials, in particular of aluminum extruded profiles. The side members 8a . 8b may be made of wood according to an alternative cost-effective variant.

The central longitudinal beam 9 is designed in the form of a hollow profile construction. There is the central longitudinal beam 9 from a plurality of longitudinally successively arranged hollow profiles, which are connected via connecting elements. The connecting elements are designed in the form of square tubes, which are inserted into the cavities of the hollow profiles. In this case, a connecting element connects two mutually arranged hollow profiles, wherein the connecting element is firmly connected only to one of the hollow sections. Due to the mobility of the non-fixed to the connecting element hollow profile length changes of the hollow profiles due to temperature fluctuations can be compensated.

Like from the 1 to 3 can be seen, are the solar modules 2 the upper row with its lower edges on the central longitudinal beam 9 stored and lie on the upper side member 8a on, with the solar modules 2 on this upper side member 8a are attached. Accordingly, the solar modules 2 the lower row with their upper edges on the central longitudinal beam 9 stored and lie on the lower side member 8b on, with the solar modules 2 on this lower side member 8b are attached.

How out 2 can be seen, is the lower part of a solar module 2 the lower row over the lower side member 8b during the upper part of a solar module 2 the upper row over the upper side member 8a protrudes. A particularly favorable arrangement is given by the fact that in each case about one third of a solar module on the respective side member 8a . 8b protrudes. Each carrier unit 5 forms at the respective post 3 a tilt-adjustable unit.

The carrier unit 5 forms as if 3 can be seen, a triangle construction, with the struts 7a . 7b each with a longitudinal end at a longitudinal end of the cross member 6 are attached and converge at an obtuse angle. In the present case, the struts 7a . 7b firmly with the crossbeam 6 connected by suitable fastening means, that is the struts 7a . 7b form with the cross member 6 a rigid, dimensionally stable construction. In principle, the struts 7a . 7b also articulated on the cross members 6 be connected. Here, in the present case, the first strut 7a shorter than the second strut 7b , whereby the carrier unit 5 already at a Sollneigungswinkelbereich of the cross member 6 is adjusted.

The cross member 6 facing away from free ends of the struts 7a . 7b are firmly connected to each other and by means of a pivot bearing on the post 3 pivoted. The pivot bearing is in the present case of one in the post 3 anchored bolt 10 or the like is formed. This is the carrier unit 5 with respect to one of the longitudinal axis of the bolt 10 formed, fixed axis of rotation at the post 3 pivoted.

Another connection between the carrier unit 5 and the post 3 is by guide means on the cross member 6 and at the post 3 receive. These guide means comprise a slot 11 in the cross member 6 and a pin 12 or the like on the post 3 , in the slot 11 of the crossbeam 6 is guided.

The width of the slot 11 and the diameter of the pin having a circular cross-section 12 are coordinated so that the pin 12 with little play in the slot 11 is guided. The slot 11 does not run along a straight line but along a curved path. The curvature of the web is at the trajectory of the cross member 6 when pivoting the carrier unit 5 adjusted with respect to the axis of rotation of the Schwenklangerung, so that the pin 12 while pivoting centrally in the slot 11 is guided and does not bump against its lateral edges.

For tilt adjustment, the entire carrier unit 5 pivoted with respect to the pivot axis of the pivot bearing, so that the cross member 6 relative to the post 3 moved and thereby the pin 12 in the slot 11 to be led. The size of the range of tilt adjustment is determined by the size of the slot 11 certainly. Once the tilt adjustment is performed, this setting is fixed, for this purpose in the pivot bearing and or in the region of the guide means suitable fasteners 16 are provided.

The pivotal mounting of the carrier unit 5 can in principle be modified to the effect that the slot 11 along a straight line. In this case, run the cross member 6 opposite ends of the struts 7a . 7b in a seesaw together. This rocker can then be on the bolt 10 not only pivoted but also moved along a trajectory during the pivoting movement.

Furthermore, the pivot bearing can also be modified to the effect that instead of the slot 11 a discrete sequence of individual holes is provided. The holes all have an identical size such that the pin 12 can be performed in the holes with little play on the post. With the holes becomes a discrete tilt angle adjustment of the solar modules 2 allows. To specify a tilt angle of the pin 12 inserted in one of the holes.

In the present case, the cross member 6 five holes up. In general, a different number of holes is possible. In the limiting case, even only one hole can be provided that for specifying the inclination angle application specific in the cross member 6 is incorporated.

4 shows in an enlarged partial view of the top 13 a post 3 mounted center longitudinal beams 9 , At the sloping top 13 of the basic body 19a of the center longitudinal member 9 includes a component of the center longitudinal member 9 forming, integral with the main body 19a trained essay 19b on, the two U-shaped shots 14 . 15 formed on opposite sides of the central longitudinal beam 9 are arranged.

The first U-shaped recording 14 is open at the top and has an upper leg 14a and a lower leg 14b on. The thigh 14a . 14b are parallel and spaced apart. Here is the upper leg 14a shorter than the one extension of the top 13 of the basic body 19a forming lower thighs 14b ,

The second U-shaped recording 15 is open at the bottom and has an upper leg 15a and a lower leg 15b on. The thigh 15a . 15b are parallel and spaced apart. Here is the upper leg 15a shorter than the one extension of the top 13 of the basic body 19a forming upper thighs 15a ,

For fixing the solar modules 2 the top row on the supporting structure 1 these will be as in 4 shown with their lower edges in the upper U-shaped receptacle 14 inserted. Accordingly, the solar modules 2 the lower row with their upper edges, as in 4 shown in the lower U-shaped receptacle 15 inserted. The U-shaped shots 14 . 15 are dimensioned so that the solar modules 2 with little play in the U-shaped shots 14 . 15 are guided. Because the lower thighs 14b . 15b the U-shaped recordings are longer than the upper legs 14a . 15a , the solar modules can 2 first on the over the upper thighs 14a . 15a protruding segments of the lower legs 14b . 15b then the solar modules 2 into the U-shaped receptacles, which means a considerable simplification of this assembly step.

Because in the U-shaped shots 14 . 15 introduced solar modules 2 flat on the top 13 of the center longitudinal member 9 rest, gives the inclination angle of the top 13 of the basic body 19a of the center longitudinal member 9 and thus the specific design of the center longitudinal member 9 the angle of inclination of the solar modules 2 on the supporting structure 1 in front.

Advantageously, the support structure forms 1 a modular system such that it has several different central longitudinal beams 9 with differently inclined tops 13 their basic body 19a having. Through the use of different central longitudinal members 9 can thus the angle of inclination of the solar modules 2 on the supporting structure 1 be varied in a simple way.

Because these solar modules 2 are inserted only in the U-shaped shots, this is enough for a secure mounting of the solar modules 2 on the supporting structure 1 not from. Therefore, the solar modules 2 on the side rails 8a . 8b on which they rest, by fastening means 16 attached.

5 shows an embodiment of such a fastener 16 , The fastener 16 forms a metal part, which has a flat top 13 for attachment to the underside of a solar module 2 having. Furthermore, the fastening means 16 one at its top 13 opening groove 16a on. This groove 16a will be in a lead 17 of the longitudinal member 8b introduced, then the fastener 16 , as in 5 represented on the underside of the solar module 2 put on and on this by means of a screw 18 attached. 5 shows the example of fixing a solar module 2 on the lower side member 8b by means of the fastening means 16 , With identically designed fasteners 16 also the attachment of solar modules 2 on the upper side member 8a ,

Advantageously, a fixation of a solar module 2 on a side member 8a . 8b by means of two fasteners 16 in the area of the opposite lateral edges of the solar module 2 be attached to the bottom. Essential here is that every fastener 16 always only for fixing a solar module 2 serves. This allows all solar modules 2 individually and independently aligned and on the side rails 8a . 8b be attached.

After the solar modules 2 the upper row in the upper pictures 14 of the center longitudinal member 9 pushed in and these solar modules 2 by means of the fastening means 16 on the upper side member 8a fixed and also the solar modules 2 the lower row in the lower pictures 15 of the center longitudinal member 9 pushed in and these solar modules 2 by means of the fastening means 16 on the lower side member 8b have been fixed, which results in 1 illustrated, fully assembled arrangement of the solar modules 2 on the supporting structure 1 ,

6 shows a variant of the embodiment of 3 and 4 , In this case, there is the central longitudinal beam 9 from a continuous over the entire length of the support structure profile, which is formed in one or more pieces. In predetermined nominal positions are discrete receiving parts of the flat top of the profile 19 showing a conical body 19a have on which a common essay 19b followed. On this recording part 19 become recording elements 20 clamped. 7 shows such a receiving element 20 in a single presentation. The receiving element 20 has an H-shaped body 20a on. At the top of the H-shaped body 20a There is a symmetrical on both sides of this protruding shell 20b , At the lower free-ending arms of the body 20a are jaws 20c ,

6 This points to the receiving part 19 of the central longitudinal carrier clamped receiving element 20 , The jaws 20c encompass the receiving part 19 so that the receiving element 20 in the in 6 Position fixed position is shown.

In this embodiment, the upper part forms 20b the upper leg and the upper side of the middle longitudinal member of the lower legs of the U-shaped receptacles for storage of the solar modules.
