MODULAR CARRIER FOR PHOTOVOLTAIC MODULES AND METHOD FOR ASSEMBLING THE MODULAR CARRIER

Description

Technical field

[0001] The invention relates to a module carrier for photovoltaic modules and a method for constructing the module carrier. The module carrier serves to install one or more photovoltaic modules on a surface such as a roof, and in particular on a flat roof. State of the art

[0002] From German patent application DE 20 2010 007 658 U1, a module support system for photovoltaic modules for installation on flat roofs is known. The module support system comprises support profiles on which high and low supports are mounted. The supports are designed as support profiles and are arranged at right angles to the support profiles, so that the support profiles and the support profiles form a grid-like structure. One high support profile and one low support profile together support a photovoltaic module. To attach the support profiles to the support profiles, two specially designed clamps, two screws, and two nuts are required at each intersection point of the grid-like structure. The screws are inserted from below through the support profile, and the clamps are inserted from above over the screws and then secured with nuts. Assembling such a module support system is relatively time-consuming.Furthermore, the installer must carry a sufficient quantity of screws, clamps, and nuts, and typically requires an electric screwdriver for the screw connections. Another disadvantage is that all support and bearing profiles must first be aligned with each other, both in terms of their angular orientation and position, before the support profiles can be attached to the bearing profiles.

[0003] Another mounting system is known from DE 20 2018 103244 U1. This system comprises an arrangement of base rails and crossbars. Support elements for holding the photovoltaic modules are attached to the base rails. Description of the invention

[0004] One object of the invention is to provide a module carrier for photovoltaic modules that is particularly easy to assemble and in which the individual components of the module carrier can be connected without the need for fastening means.

[0005] Advantageously, the module carrier can be assembled without special tools. Almost any hand tool that can be used as a lever is suitable.

[0006] The problem is solved by a module carrier for photovoltaic modules with the features specified in claim 1.

[0007] The inventive module support for photovoltaic modules comprises rod-shaped connecting profiles and base plates on which supports for carrying the photovoltaic modules are attached. The base plates can be connected to one another by means of the rod-shaped connecting profiles. Each base plate has a longitudinal connector

[0008] The longitudinal connector receptacle includes a recess into which one of the connecting profiles can be inserted in a first insertion direction defined by the longitudinal connector receptacle. The longitudinal connector receptacle comprises a protrusion that is arranged transversely to the first insertion direction. Due to plastic deformation, a section of the connecting profile inserted in the longitudinal connector receptacle projects into the protrusion and forms a positive connection with it.

[0009] Advantageous further developments of the invention result from the features specified in the dependent patent claims.

[0010] In one embodiment of the module carrier according to the invention, the base plate has a cross-connector receptacle which is designed to provide a second insertion direction that runs perpendicular to the first insertion direction, so that one of the rod-shaped connecting profiles can be inserted into the cross-connector receptacle in the second insertion direction.

[0011] In a further embodiment of the module carrier according to the invention, the base plate has a longitudinal side and an end face. The longitudinal connector receptacle and a further longitudinal connector receptacle are arranged on the end face, so that two of the rod-shaped connecting profiles can be inserted into the longitudinal connector receptacles in the first insertion direction.

[0012] In an additional embodiment of the module carrier according to the invention, the base plate has a second end face. At least one additional longitudinal connector receptacle is arranged on the second end face, so that one of the rod-shaped connecting profiles can be inserted into the additional longitudinal connector receptacle in a direction opposite to the first insertion direction.

[0013] In a further development of the modular carrier according to the invention, the base plate is made of plastic or concrete.

[0014] In another embodiment of the inventive module carrier, the plastic used is recycled plastic. This allows the module carrier to be manufactured in a particularly cost-effective and environmentally friendly manner.

[0015] In a further development of the modular carrier according to the invention, the longitudinal connector receptacle has a depth stop to limit the insertion depth. The longitudinal connector receptacle is designed as a cap at the top in the area of ​​the depth stop, under which the connecting profile can be inserted.

[0016] Advantageously, the longitudinal connector receptacle of the modular carrier according to the invention has a guide rib and a guide groove arranged parallel to it. The rod-shaped connecting profile is profiled such that it forms a positive fit with the guide rib and the guide groove when inserted into the longitudinal connector receptacle. This creates a particularly stable connection.

[0017] Furthermore, the modular support according to the invention can be designed so that the connecting profile is made of aluminum. Such a connecting profile can be machined with standard tools and in a reliable process.

[0018] The modular support according to the invention may be provided in that the base plate has a hump onto which one of the supports can be slid. The hump and the support are designed such that, in the assembled state, the support is positively connected to the hump in the vertical direction.

[0019] In one embodiment of the modular support according to the invention, the support has tabs at the bottom. The hump includes laterally arranged grooves into which the tabs of the support can be inserted.

[0020] In a further embodiment of the modular support according to the invention, the base plate has a slot next to the hump, and the support has a section that can be plastically deformed with a hand tool. In the assembled state, the plastically deformed section projects into the slot and forms a positive fit with the slot.

[0021] In another embodiment of the modular support according to the invention, one part of the supports is lower than another part of the supports.

[0022] In an additional embodiment of the modular support according to the invention, the supports are made of aluminum.

[0023] In a further development of the modular support according to the invention, the connecting profile is covered with a strip-shaped, flexible component. This strip-shaped, flexible component can, for example, be a mesh or a fabric. The ballast is arranged on this component.

[0024] Furthermore, a method for assembling the module carrier for photovoltaic modules described above is proposed. One of the rod-shaped connecting profiles is inserted into the longitudinal connector receptacle. Then, using a hand tool that can be used as a lever, the section of the connecting profile inserted in the longitudinal connector receptacle is pressed into the recess.

[0026] One possible embodiment of the module carrier 1 for photovoltaic modules 10 is shown in the Figures 1 to 4The diagram illustrates the structure. For clarity, a coordinate system is shown in the figures. The module support 1 comprises several base plates 3 and 103, which can be connected by longitudinal connecting profiles 4 (parallel to the y-axis) and transverse connecting profiles 2 (parallel to the x-axis). The size of the module support 1 is freely selectable. The module support 1 can be constructed with any number of base plates 3 and 103 and connecting profiles 2 and 4.

[0027] In the following, it is assumed that each photovoltaic module 10 is assigned a module support array; all module support arrays together form the entire module support 1. The size of an individual module support array can be adapted to the size of the photovoltaic module 10 to be mounted. For this purpose, the connecting profiles 2 and / or 4 are cut to the required length. In this way, a module support array with a freely selectable width B and a freely selectable length L can be constructed.

[0028] Two adjacent photovoltaic modules 10 are attached to one of the supports 5, 6 by means of a module clamp (not shown in the figures). The module clamp defines the distance between the two photovoltaic modules 10. The hump 3.13 can have a web 3.22 in the middle (see Figures 6 and 7) exhibiting a width equal to the distance between two adjacent photovoltaic modules 10. Since in this case the connecting profile 2 has the same length as the photovoltaic module 10 to be installed, it is sufficient to know the length of the photovoltaic module 10 in order to be able to shorten the connecting profile 2 to the correct length.

[0029] Connecting profiles 2 and / or 4 can, for example, be stored as standard lengths and cut to the required length at the installation site if needed. Alternatively, connecting profiles 2 and / or 4 can be pre-cut to the desired length or kept as pre-assembled components.

[0030] As from Figure 1As can be seen, it is not necessary to connect the base plates 3 of each row to each other via a connecting profile 2. The connecting profiles 2 primarily serve to define the transverse spacing between the base plates 3. In the longitudinal direction, two base plates 3 are preferably connected to each other by two connecting profiles 4 each. The connecting profiles 2 define the longitudinal spacing between the base plates 3 and give the entire module carrier 1 sufficient stability.

[0031] Base plates 103 can be provided in the edge area of ​​the module carrier 3. These differ from the base plates 3 primarily in that they have receptacles for the connecting profiles 4 on only one of the two end faces, rather than on both. The advantage is that the base plates 103 protrude only slightly beyond the photovoltaic modules 10, thus reducing the risk of tripping when walking on the photovoltaic module array.

[0032] High supports 5 and low supports 6 are arranged or can be arranged on the base plates 3 and 103. The photovoltaic modules 10 are attached to the supports 5 and 6. If the supports 5 and 6 are, as shown in the Figures 1 to 4 As shown, the photovoltaic modules 10 are arranged in the following configuration: Figure 3 The arrangement shown is as follows. In this arrangement, two adjacent photovoltaic modules 10 are inclined towards each other. A path 17 for personnel can be provided between the slightly more widely spaced photovoltaic modules 10.

[0033] In order to securely fix the entire photovoltaic system to the ground so that it meets the relevant standards regarding possible wind forces, the module carrier 1 can be provided with ballast at one or more points.

[0034] One way to add the ballast is to first, as in Figure 4A strip-shaped, flexible component 18 is shown. Preferably, the strip-shaped, flexible component 18 is arranged in the transverse direction (parallel to the x-axis). The strip-shaped, flexible component 18 can be, as shown in Figure 4 The base plates 3 are shown. Alternatively, or additionally, the longitudinal connections 4 can also be covered (not shown in the figures). Component 18 can then be covered with ballast in the form of gravel, crushed stone, or the like.

[0035] Alternatively or additionally, the ballast can consist of larger stones, concrete slabs, or concrete blocks. It is preferably placed below the photovoltaic modules 10 on the connecting profiles 4.

[0036] The base plate can be the one in the Figures 6 to 8 Base plate 3 was shown. Alternatively or additionally, the one in Figure 5The embodiment of the base plate 103 is shown. The base plates 3 and 103 each have two longitudinal sides 3.20 and two end faces 3.21.

[0037] The base plate 3 can, as in Figure 6 shown, it is symmetrical to the midline ML and may have a hump 3.13 in the middle. If the hump 3.13 is as shown in Figure 6 As shown, it can accommodate both a support 6 and a connecting profile 2 (see Figure 12 ).

[0038] To enable the connecting profile 2 to be attached to the hump 3.13 or to the base plate 3, the hump 3.13 has a receptacle 3.14 that defines the insertion direction Rx for the connecting profile 2. The receptacle 3.14, also referred to as the cross connector receptacle, preferably extends parallel to the center line ML and has a projection 3.16 that extends transversely to the center line ML.

[0039] To connect the connecting profile 2 to the base plate 3, proceed as follows. First, insert the connecting profile 2 into the receptacle 3.14 until it stops. Then, insert a hand tool 20, for example a screwdriver, into the groove 2.3 of the connecting profile 2 (see Figures 10 and 15 The screwdriver, serving as a lever, is now pressed transversely to the insertion direction Rx in the direction of the protrusion 3.16. This deforms a section 2.1 of the web 2.4 so that it projects into the protrusion 3.16. Preferably, the screwdriver is pressed firmly against the web 2.4 until the web 2.4 splits and forms a positive fit with the protrusion 3.16 as the lug 2.1. Because the web 2.4 rests against the wall of the hump 3.13 to the left and right of the lug 2.1, the web 2.4 is not deformed in these areas.

[0040] The recess 3.14 can additionally have a further, identically shaped recess 3.15 opposite the recess 3.16. This has the advantage that one web 2.4 of the connecting profile 2 can be pressed into the recess 3.16 and / or the other web 2.4 of the connecting profile 2 can be pressed into the other recess 3.15.

[0041] To prevent the screwdriver from slipping out of the groove 2.3 during pressing, a ridge 2.2 can be provided in the lower part of the groove 2.3. When the screwdriver blade rests against the ridge 2.4 below the ridge 2.2, the ridge 2.2 prevents the blade from slipping upwards out of the groove 2.3.

[0042] During the Figures 15 and 16In the illustrated embodiment, the connecting profile 2 is axially symmetrical (axis of symmetry parallel to the z-axis). This has the advantage that the orientation of the connecting profile 2 does not need to be considered during assembly. The connecting profile 2 thus formed has two identically constructed, plastically deformable webs 2.4. The groove 2.3 is located between the two webs 2.4.

[0043] Preferably, on both sides of the hump 3.13 there are two protrusions 3.12 and a slot 3.11 between each. To allow the support 6 to be easily attached to the hump 3.13 or to the base plate 3, the hump 3.13 has two grooves 3.10 on its sides. The support 6 has two corresponding tabs 6.1 on its underside. To mount the support 6 on the base plate 3, the tabs 6.1 are pushed laterally into the grooves 3.10. This prevents the support 6 from sliding upwards off the hump 3.13. The screwdriver blade is then inserted into the groove 6.4 of the support 6 (see figure). Figure 12 and 22The screwdriver, serving as a lever, is now pressed transversely to the insertion direction Rx in the direction of slot 3.11. This deforms a section of the ridge 6.2 so that it projects into slot 3.11. Preferably, the screwdriver is pressed firmly against the ridge 6.2 until it splits, forming a lug and interlocking with slot 3.11 and the two protrusions 3.12. Because the ridge 6.2 rests against both protrusions 3.12 to the left and right of the lug, it is not deformed in these areas.

[0044] On both end faces 3.20, the base plate 3 has, as in Figure 7 Two receptacles 3.1 are shown. One of the connecting profiles 4 can be inserted into each receptacle 3.1, which is also referred to as a longitudinal connector receptacle, and connected to the base plate 3 (see Figure 9 and 13The recesses 3.1 define the insertion direction Ry for the connecting profiles 4. The recess 3.1 preferably extends parallel to the longitudinal axis LA of the base plate 3 and has a first projection 3.2 that preferably extends transversely to the longitudinal axis LA. At the rear end of the recess 3.1 is a depth stop 3.4 that limits the insertion depth of the connecting profile 4.

[0045] A cap 3.3 may be provided on the upper side of the base plate 3 in the area of ​​the depth stop 3.4. When the connecting profile 4 is inserted into the receptacle 3.1 up to the depth stop 3.4, the cap 3.3 prevents the connecting profile 4 from sliding upwards out of the receptacle. The cap 3.3 is particularly useful when leverage is applied to the connecting profile 4 with a screwdriver. Furthermore, the cap 3.3 may be designed to serve as a stop for the hand tool 20 (see Figure 1). Figure 9 ).

[0046] The connecting profile 4 can be connected to the base plate 3 as follows. First, insert the connecting profile 4 into the receptacle 3.1 until it stops. Then, insert the screwdriver into the groove 4.3 of the connecting profile 4 (see Figure 9 and 13The screwdriver, serving as a lever, is now pressed transversely to the insertion direction Ry in the direction of the recess 3.2. This deforms the section 4.1 of the web 4.4 located in front of the recess, so that it projects into the recess 3.2. Preferably, the screwdriver is pressed firmly against the web 4.4 until it splits, and the resulting lug 4.1 forms a positive fit with the recess 3.2. Because the web 4.4 rests against the wall of the receptacle 3.1 to the left and right of the lug 4.1, it is not deformed in these areas. The receptacle 3.1 is advantageously equipped with a guide rib 3.5. The connecting profile 4 has a profile adapted to the guide rib 3.5. To facilitate the insertion of the connecting profile 4 into the receptacle 3.1, the guide rib 3.5 can be conical at its front section 3.6.

[0047] The recess 3.7 can be provided optionally. In particular, if the base plate 3 is manufactured using a casting process, the recess 3.7 can be helpful in order to be able to pull out the mold during demolding.

[0048] To prevent the screwdriver from slipping out of the groove 4.3 of the connecting profile 4 during pressing, a bead 4.2 can be provided in the lower area of ​​the groove 4.3. Figures 13 and 14 Figure 1 shows an embodiment of the connecting profile 4 with such a bead 4.2. When the screwdriver blade rests against the connecting profile 4 under the bead 4.2, the bead 4.2 prevents the blade from slipping upwards out of the groove 4.3.

[0049] In the embodiment shown in the figures, the base plate 3 has a protrusion 3.9 at both the front and rear for attaching the supports 5. Adjacent to the protrusion 3.9 are two raised sections 3.8 and a slot 3.11 between them. To allow the support 5 to be attached to the protrusion 3.9 and thus to the base plate 3, the protrusion 3.9 has two grooves 3.10 on its side. The support 5 has two corresponding tabs 5.1 at its bottom. To mount the support 5 on the base plate 3, the tabs 5.1 are pushed laterally into the grooves 3.10. This prevents the support 5 from being pulled upwards off the protrusion 3.9. The blade of the screwdriver is then inserted into the groove 5.4 of the support 5. Figure 11 and 21The screwdriver, serving as a lever, is now pressed transversely to the insertion direction Rx in the direction of slot 3.11. This deforms a section of the ridge 5.2 so that it protrudes into slot 3.11. Preferably, the screwdriver is pressed firmly against the ridge 5.2 until it splits, forming a lug and interlocking with slot 3.11 and the two protrusions 3.8. Because the ridge 5.2 rests against both protrusions 3.8 to the left and right of the lug, it is not deformed in these areas.

[0050] In Figure 8 Figure 1 shows an embodiment of the base plate 3 in a three-dimensional, oblique view from below. The base plate 3 can have knobs 3.25 on its underside. This increases the slip resistance and improves ventilation.

[0051] Furthermore, the base plate 3 may have markings 3.26 indicating where it can be advantageously separated. If only a portion of the base plate 3 is required, it can be separated at the location of one of these markings 3.26. The markings 3.26 can be helpful, for example, when the base plates located at the edges of the photovoltaic system need to be cut to the same length. However, the base plate can also be separated at any other point if necessary.

[0052] The connecting profiles 2 are particularly easy to stack and save space. Figure 17 shows a stack of connection profiles 2 in a three-dimensional view and Figure 18 shows the stack in a front view.

[0053] A rod-shaped connecting profile is understood here to be a component whose width and height are relatively small compared to its length. In cross-section, the component has a profile adapted to the technical requirements.

[0054] A strip-shaped, flexible component 18 is defined here as an elongated, flat component that serves as a base for the ballast. The strip-shaped component 18 can be, for example, a sheet of roofing felt, a net, a fabric, or a mat. Gravel, crushed stone, or stones, for example, can be used as ballast.

[0055] In the Figures 19 and 20 Another embodiment of the base plate is shown, which is designated by reference numeral 203. Furthermore, the Figures 19 and 20 another embodiment of the connecting profile, which is marked with reference numeral 104.

[0056] The base plate 203 differs from the base plate 3 only in the area of ​​the longitudinal connector receptacle 203.1. The connecting profile 104 does not differ from the connecting profile 4 in cross-section, but only in the plug-in area.

[0057] The module carrier 1 can also be constructed from several of the base plates 203 and the connecting profiles 104. The rod-shaped connecting profile 104 has a notch 104.3 in the area where it is inserted into the receptacle 203.1. The receptacle 203.1 of the base plate 203 is equipped with a bead 203.3. The notch 104.3 on the connecting profile and the bead 203.3 on the receptacle together form a snap connection. To connect the connecting profile 104 and the base plate 203, it is sufficient to insert the connecting profile 104 firmly into the receptacle 203.1 until the snap connection engages.

[0058] Base plate 3, as well as base plates 103 and 203, can be made of plastic, preferably recycled plastic. Casting or injection molding processes are suitable for producing the base plates in a particularly cost-effective manner.

[0059] The module support 1 can be oriented and the supports 5 and 6 can be arranged so that the photovoltaic modules 10 are oriented in an east-west direction and inclined at an angle α of, for example, α = 10° to the horizontal. Alternatively, the module support 1 can also be oriented so that the photovoltaic modules 10 are oriented in a north-south direction. In principle, the orientation and shape of the module support 1 can be adapted to the local conditions and requirements.

[0060] The supports 5 and 6 can be arranged on the base plate 3 in such a way that the individual photovoltaic modules 10 do not shade each other.

[0061] By means of a suitable combination of low and high supports 5 and 6 and the flat design of the base plate 3, the photovoltaic modules 10 can be arranged in a particularly aerodynamic manner. Such a particularly favorable aerodynamic arrangement of the photovoltaic modules 10 is in Figure 4 As shown. With this arrangement, sufficient weighting or fixing of the entire photovoltaic system can be achieved with very little ballast.

[0062] The narrow supports 5 and 6 contribute to the fact that the module carrier 1 requires exceptionally little material.

[0063] The preceding description of the embodiments according to the present invention serves only for illustrative purposes. Various changes and modifications are possible within the scope of the invention. For example, the different embodiments described in the Figures 1 to 22The components of the module carrier shown can also be combined with one another in a manner other than that shown in the figures. Furthermore, the components of the module carrier shown can be assembled to form a module carrier with a different shape than that shown in the figures. The invention is defined by the present claims. Reference symbol list
