Technical Field
[0001] This application relates to the photovoltaic field, specifically to photovoltaic module installation structures and photovoltaic roofs. Background Technology
[0002] In some related technologies, photovoltaic modules are installed on the roof using methods such as screw connections, which results in low installation efficiency. Utility Model Content
[0003] This application provides a photovoltaic module installation structure and a photovoltaic roof to solve the problem of low installation efficiency of photovoltaic modules.
[0004] In a first aspect, this disclosure provides a photovoltaic module mounting structure, which includes a guide rail structure, an adhesive structure, and a photovoltaic module. The guide rail structure includes a first guide rail and a second guide rail. The photovoltaic module is supported on the first guide rail and the second guide rail, and is respectively bonded to the first guide rail and the second guide rail by the adhesive structure. The first guide rail defines a receiving space for accommodating the power connection structure of the photovoltaic module.
[0005] In one possible implementation, the first guide rail includes two first sidewalls and two first top walls. The two first sidewalls are spaced apart from each other, and a receiving space is located between the two first sidewalls. The two first top walls are respectively connected to the two first sidewalls, and the surfaces of the two first top walls facing the photovoltaic module are respectively recessed with first adhesive grooves. The photovoltaic module is supported on the two first top walls and is bonded to the two first top walls by an adhesive structure housed in the first adhesive grooves.
[0006] In one possible implementation, the two first top walls extend in a direction away from the receiving space, protruding from the corresponding first side walls.
[0007] In one possible implementation, the first guide rail further includes a first bottom wall and two inclined walls. The first bottom wall is connected to one end of the two first side walls away from the photovoltaic module, and the two inclined walls are located between the two first side walls and respectively inclinedly support the first bottom wall and the two first side walls.
[0008] In one possible implementation, the first guide rail is configured to be fixed to a mounting base by connecting bolts. A first bottom wall is provided with a connecting groove, into which the bolt head of the connecting bolt engages, and the bolt shank of the connecting bolt is used for connection to the mounting base.
[0009] In one possible implementation, the photovoltaic modules are arranged in multiple rows, spaced apart along a first direction. There are multiple first guide rails, and at least some of the first guide rails are end guide rails. The two first top walls of each end guide rail respectively support and connect two adjacent photovoltaic modules along the first direction.
[0010] In one possible implementation, the power connection structure of the photovoltaic module extends along a second direction, which is perpendicular to the first direction. There are multiple first rails, each extending along the second direction. At least a portion of the first rails are intermediate rails, and the power connection structure is housed within the receiving space of the intermediate rail.
[0011] In one possible implementation, the second guide rail includes a second top wall and two second side walls, the two second side walls being spaced apart from each other, and the second top wall being connected between the two second side walls. A second adhesive groove is recessed into the surface of the second top wall facing the photovoltaic module. The photovoltaic module is supported on the second top wall and bonded to the second top wall by an adhesive structure housed in the second adhesive groove.
[0012] In one possible implementation, the second guide rail is circumferentially closed in a plane perpendicular to the length direction of the second guide rail, and the load-bearing capacity of the second guide rail is greater than that of the first guide rail.
[0013] In one possible implementation, the photovoltaic modules are arranged in multiple rows along a first direction. There are multiple first guide rails, two of which are end rails, and the rest are intermediate rails. The end rails are located at the ends of the photovoltaic modules along the first direction and simultaneously support and connect two adjacent photovoltaic modules. The intermediate rails are spaced apart between the two end rails and support the photovoltaic modules at their midpoints along the first direction. Second guide rails support the photovoltaic modules at their midpoints along the first direction and are located between adjacent first rails.
[0014] Secondly, this disclosure provides a photovoltaic roof, which includes a roof structure and the aforementioned photovoltaic module mounting structure. A guide rail structure supports and connects to the roof structure.
[0015] In one possible implementation, the roof structure is made of corrugated steel sheets, and the guide rail structure is fixedly connected to the roof structure on the side away from the photovoltaic modules by clamps.
[0016] In summary, according to the above description, in some embodiments of the photovoltaic module installation structure of this disclosure, the photovoltaic modules are fixedly installed by bonding and supporting them to the first and second guide rails using an adhesive structure. Compared with traditional mechanical installation methods (such as bolted connections), this solution has lower construction costs, higher construction efficiency, and shorter construction time.
[0017] Furthermore, the power connection structure of the photovoltaic module is housed within the space of the first guide rail, reducing the impact of exposed wiring on appearance and safety. Attached Figure Description

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0035] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0036] Example
[0037] See Figure 1 This embodiment provides a photovoltaic roof 100, which includes a roof structure 110 and a photovoltaic module mounting structure 130.
[0038] The specific composition of the roof structure 110 can be configured as needed. For example, the roof structure 110 can be composed of color steel tiles 111, and the photovoltaic module installation structure 130 can be fixedly connected to the roof structure 110 composed of color steel tiles 111 through a matching clamp 120.
[0039] It should be noted that, in addition to installing the photovoltaic module 40 on the roof structure 110, the photovoltaic module mounting structure 130 of this embodiment can also be installed on other mounting bases, such as the roof of a rain shelter, the ground or other suitable locations, and is not limited here.
[0040] See Figure 2 and Figure 3 The photovoltaic module mounting structure 130 of this embodiment includes a guide rail structure 131, an adhesive structure 30, and a photovoltaic module 40. The guide rail structure 131 supports and is connected to the roof structure 110. For example, the side of the guide rail structure 131 facing away from the photovoltaic module 40 is fixedly connected to the roof structure 110 by a clamp 120.
[0041] In this embodiment, the guide rail structure 131 includes two different guide rails, namely a first guide rail 10 and a second guide rail 20. The photovoltaic module 40 is supported on the first guide rail 10 and the second guide rail 20, and is connected by an adhesive structure 30 (visible in...). Figures 10-12 They are respectively bonded to the first guide rail 10 and the second guide rail 20. The specific bonding method will be described below.
[0042] See also Figure 4 and Figure 5 In this embodiment, the photovoltaic module 40 includes a photovoltaic panel 42 and a power connection structure 41. The power connection structure 41 includes a positive terminal 41a, a negative terminal 41b, and a junction box 41c. The positive terminal 41a and the negative terminal 41b are electrically connected to different junction boxes 41c via different cables 41d. The photovoltaic panel 42 in this embodiment can be understood as the part of the photovoltaic module 40 excluding the power connection structure 41.
[0043] The photovoltaic module 40 is roughly rectangular, with its length direction parallel to the first direction X and its width direction parallel to the second direction Y.
[0044] The power connection structure 41 protrudes from the back surface P1 of the photovoltaic module 40 and is arranged approximately along a straight line parallel to the width direction of the photovoltaic module 40 (i.e., the second direction Y). The positive terminal 41a and the negative terminal 41b are located at opposite ends of the photovoltaic module 40 along its width direction. Thus, when multiple photovoltaic modules 40 are arranged sequentially along the width direction, the positive terminal 41a of one photovoltaic module 40 can be plugged into the negative terminal 41b of an adjacent photovoltaic module 40 to achieve electrical connection between two adjacent photovoltaic modules 40 in the width direction. This connection is convenient and facilitates the arrangement of the photovoltaic modules 40. The photovoltaic module 40 located on the outermost side of the width direction can be connected to an external circuit (such as an external power grid) through its positive terminal 41a or negative terminal 41b.
[0045] The following is combined Figure 6 and Figure 7 The first guide rail 10 of this embodiment is described by way of example.
[0046] See also Figure 6 and Figure 7 In this embodiment, the first guide rail 10 is a long strip with an open top surface.
[0047] For example, the first guide rail 10 includes two first sidewalls 11 and two first top walls 12. The two first sidewalls 11 are spaced apart from each other and define a receiving space Q1 between them. The receiving space Q1 can be used to accommodate other structures, such as the power connection structure 41 of the photovoltaic module 40, etc.
[0048] Two first top walls 12 are respectively connected to two first side walls 11, and the surfaces of the two first top walls 12 facing the photovoltaic module 40 are respectively provided with first adhesive grooves C1. In this embodiment, the two first top walls 12 are spaced apart from each other so that the receiving space Q1 is open, which facilitates the installation of structures such as the power connection structure 41 into the receiving space Q1.
[0049] In this embodiment, the two first top walls 12 extend outward from the receiving space Q1, respectively, to form corresponding first side walls 11, thereby increasing the support area of the first top walls 12 for the photovoltaic module 40. The first top walls 12 also extend outward from the receiving space Q1 in opposite directions along the second direction Y, so that the first top walls 12 and the first side walls 11 form a near-T-shaped structure, thereby increasing the support area for the photovoltaic module 40.
[0050] The photovoltaic module 40 is supported by two first top walls 12 and can be accommodated by an adhesive structure 30 (see) placed in the first adhesive tank C1. Figure 10 or Figure 11 It is bonded to the two first top walls 12. The adhesive structure 30 can be liquid glue, tape or other structural adhesive, which is not limited here.
[0051] In this embodiment, the first adhesive container C1 can accommodate the adhesive structure 30, which helps to keep the adhesive structure 30 inside. Especially when the adhesive structure 30 is liquid adhesive, the first adhesive container C1 also helps to prevent the adhesive structure 30 from overflowing.
[0052] See also Figure 7 In this embodiment, the first guide rail 10 further includes a first bottom wall 13 and two inclined walls 14. The first bottom wall 13 is connected to one end of the two first side walls 11 away from the photovoltaic module 40, and the two inclined walls 14 are located between the two first side walls 11, and respectively inclinedly support the first bottom wall 13 and the two first side walls 11 to improve the structural rigidity and stability of the first guide rail 10.
[0053] In this embodiment, the first bottom wall 13 is provided with a connecting groove C31, which facilitates the mating of a connecting bolt 140 (visible in...). Figure 10 This allows the first bottom wall 13 to be connected to other structures (such as the roof structure 110 or a matching clamp 120). To form the connecting groove C31, a recessed wall is provided at the middle position of the first bottom wall 13, which surrounds the aforementioned connecting groove C31.
[0054] The following is combined Figure 8 and Figure 9 The second guide rail 20 of this embodiment is described by way of example.
[0055] See Figure 8 and Figure 9 In this embodiment, the second guide rail 20 is a long strip with no opening on the top surface.
[0056] In this embodiment, the second guide rail 20 includes a second top wall 22 and two second side walls 21, the two second side walls 21 being spaced apart from each other, and the second top wall 22 being connected between the two second side walls 21. A second adhesive groove C2 is recessed on the surface of the second top wall 22 facing the photovoltaic module 40. The photovoltaic module 40 is supported on the second top wall 22 and is connected by an adhesive structure 30 (see [reference needed]) housed in the second adhesive groove C2. Figure 12 It is adhered to the second top wall 22. The second adhesive reservoir C2 can be set at the middle position of the second top wall 22 along the second direction Y.
[0057] The second guide rail 20 also includes a second bottom wall 23, which is provided with a connecting groove C32. The connecting groove C32 facilitates the use of a connecting bolt 140 to connect the second bottom wall 23 to other structures (such as the roof structure 110 or a matching clamp 120). To form the connecting groove C32, a concave wall is provided at the middle position of the second bottom wall 23, which surrounds the aforementioned connecting groove C32.
[0058] See also Figure 9In a plane perpendicular to the length direction (i.e., the second direction Y) of the second guide rail 20, the second guide rail 20 is circumferentially closed into a complete ring, that is, the second top wall 22, the second bottom wall 23, and the two second side walls 21 form a closed ring. Thus, the second guide rail 20 has a greater load-bearing capacity, for example, greater than the first guide rail 10, which is beneficial for reliably supporting the photovoltaic module 40 to withstand loads such as being stepped on during installation or use.
[0059] In this embodiment, there are multiple photovoltaic modules 40. During installation, the multiple photovoltaic modules 40 can be distributed in a matrix form on the roof structure 110 within the plane defined by the first direction X and the second direction Y.
[0060] For example, such as Figure 1 In the photovoltaic roof 100 shown, the photovoltaic modules 40 are arranged in two columns and four rows, that is, there are two columns of photovoltaic modules 40 distributed along the first direction X, and each column of photovoltaic modules 40 includes four photovoltaic modules 40 arranged along the second direction Y.
[0061] In the guide rail structure 131 of this embodiment, there are multiple first guide rails 10, each extending along the second direction Y. At least a portion of the first guide rails 10 are end guide rails 10a, which support the ends of the photovoltaic module 40 along the first direction X. At least a portion of the first guide rails 10 are intermediate guide rails 10b, which support the middle position of the photovoltaic module 40 along the first direction X.
[0062] For example, in one embodiment, the guide rail structure 131 supporting each row of photovoltaic modules 40 has three first guide rails 10 and two second guide rails 20. Two of the three first guide rails 10 are end guide rails 10a, and the other is a middle guide rail 10b. The guide rail structure 131 supporting each row of photovoltaic modules 40 includes end guide rails 10a, second guide rails 20, middle guide rails 10b, second guide rails 20, and end guide rails 10a arranged sequentially and at intervals along a first direction X.
[0063] Two end rails 10a are located at the two ends of each row of photovoltaic modules 40 along the first direction X, and simultaneously support and connect two adjacent rows of photovoltaic modules 40. A middle rail 10b is spaced between the two end rails 10a and supports the photovoltaic module 40 at its midpoint along the first direction X. A second rail 20 supports the photovoltaic module 40 at its midpoint along the first direction X and is located between adjacent first rails 10.
[0064] Figure 10 for Figure 3 Enlarged view at point C, Figure 11 for Figure 3 Enlarged view of point D, Figure 12 for Figure 3 Enlarged view of point E. Figures 10-12Three different connection nodes of the photovoltaic module 40 are described by way of example, and will be described separately below.
[0065] Figure 10 In the connection node shown, the end rail 10a supports and connects the ends of two adjacent photovoltaic modules 40 along the first direction X.
[0066] See Figure 10 A clamp 120 is connected to the roof structure 110. The end guide rail 10a is connected to the clamp 120 by a connecting bolt 140. Specifically, the bolt head of the connecting bolt 140 is inserted into the connecting groove C31 of the first bottom wall 13 of the end guide rail 10a. The thread of the connecting bolt 140 (such as a hexagonal bolt) is threaded and locked with the nut, and is locked to the clamp 120.
[0067] The adjacent ends of two photovoltaic modules 40 along the first direction X are supported along the height direction Z on two first top walls 12 of the end guide rail 10a, and are bonded together with the first top walls 12 by the adhesive structure 30 in the first adhesive groove C1 of the two first top walls 12. There can be a certain gap between the two adjacent photovoltaic modules 40.
[0068] Figure 11 In the connection node shown, the middle guide rail 10b supports and connects to the middle position of the photovoltaic module 40 along the first direction X (it can be the exact center or not).
[0069] See Figure 11 A clamp 120 is connected to the roof structure 110. The intermediate guide rail 10b is connected to the clamp 120 by a connecting bolt 140. Specifically, the bolt head of the connecting bolt 140 is inserted into the connecting groove C31 of the first bottom wall 13 of the intermediate guide rail 10b. The thread of the connecting bolt 140 (such as a hex bolt) is threaded and locked with the nut, and is locked to the clamp 120.
[0070] The photovoltaic module 40 is supported along the height direction Z at its middle position on the two first top walls 12 of the middle guide rail 10b, and is bonded to the first top walls 12 by the adhesive structure 30 in the first adhesive groove C1 of the two first top walls 12.
[0071] The accommodating space Q1 of the intermediate guide rail 10b is larger than the power connection structure 41 of the photovoltaic module 40. The power connection structure 41 of the photovoltaic module 40 is accommodated in the accommodating space Q1 of the intermediate guide rail 10b and is covered by the photovoltaic module 40 and is not or basically not exposed, which improves the aesthetics of the photovoltaic module 40 after installation.
[0072] Figure 12In the connection node shown, the second guide rail 20 supports and connects to the middle position of the photovoltaic module 40 along the first direction X (it can be the exact center or not).
[0073] See Figure 12 A clamp 120 is connected to the roof structure 110. The second guide rail 20 is connected to the clamp 120 by a connecting bolt 140. Specifically, the bolt head of the connecting bolt 140 is inserted into the connecting groove C32 of the second bottom wall 23 of the second guide rail 20. The thread of the connecting bolt 140 (such as a hexagonal bolt) is threaded and locked with the nut, and is locked to the clamp 120.
[0074] The photovoltaic module 40 is supported at its middle position along the height direction Z on the second top wall 22 of the second guide rail 20, and is bonded to the second top wall 22 by the adhesive structure 30 in the second adhesive groove C2 of the second top wall 22.
[0075] In this embodiment, the second guide rail 20 is arranged between adjacent first guide rails 10. Since the second guide rail 20 is circumferentially closed, it has a higher support capacity, which helps to improve the reliability of supporting the photovoltaic module 40.
[0076] In this embodiment, during the installation of the photovoltaic module mounting structure 130, adhesive structures 30 are first applied to the first adhesive groove C1 of the first guide rail 10 and the second adhesive groove C2 of the second guide rail 20. Then, the photovoltaic module 40 is laid, with its power connection structure 41 housed in the receiving space Q1 of the intermediate guide rail 10b. The photovoltaic module 40 is then supported and bonded to each of the first guide rails 10 and the second guide rails 20, thus achieving a fixed installation of the photovoltaic module 40. Compared to traditional mechanical installation methods (such as bolted connections), this solution has lower construction costs, higher construction efficiency, and a shorter construction period.
[0077] Furthermore, the power connection structure 41 of the photovoltaic module 40 is housed within the housing space Q1, reducing the impact of exposed wiring on appearance and safety issues.
[0078] The staggered arrangement of the first guide rail 10 and the second guide rail 20 facilitates the connection of adjacent rows of photovoltaic modules 40 and provides reliable support for all parts of the photovoltaic modules 40.
[0079] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
