Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a frame and mounting bracket for a lightweight photovoltaic module. Background Technology

[0002] Lightweight photovoltaic (PV) modules offer advantages such as light weight and flexibility, allowing them to be easily attached to building exteriors like roofs, corrugated steel sheets, and walls using structural adhesive. However, when installing PV modules on corrugated steel sheets, the traditional method involves applying structural adhesive with a caulking gun to the raised edges of the sheet before placing the module on top, bonding the back of the module to the adhesive-coated edges. While simple and convenient, this method becomes problematic when the corrugated steel roof requires renovation or replacement. The traditional method, which integrates the module and sheet, makes separation difficult and prone to damage. Furthermore, the uneven structure of the corrugated steel sheet leaves some lightweight PV modules suspended, increasing their susceptibility to deformation under prolonged unsupported conditions, impacting power generation efficiency and lifespan.

[0003] CN219834021U discloses a lightweight, flexible photovoltaic module quick-assembly and disassembly bracket, including a positioning seat and a guide seat located between the protruding ridges of a corrugated steel sheet. The positioning seat and the guide seat cooperate to allow the module to move along the length of the positioning seat. However, the direction of movement of the module is still greatly restricted, and it can only move in the direction set by the positioning seat during assembly and disassembly. Compared with traditional installation methods, although there is an improvement, it is not sufficient.

[0004] Therefore, providing a lightweight photovoltaic module mounting bracket that is easy to install and disassemble and has a stable structure is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] One of the objectives of this utility model is to provide a mounting bracket frame for lightweight photovoltaic modules. This mounting bracket frame can be fixedly installed according to the specifications and shape of the lightweight photovoltaic modules, thus being applicable to installation scenarios of various specifications of lightweight photovoltaic modules. Moreover, the number of bracket frames can be adjusted according to the user's requirements, further improving the support force of the bracket for the lightweight photovoltaic modules, thereby improving the stability of the lightweight photovoltaic modules.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A lightweight photovoltaic module mounting bracket frame includes a support structure and a fixing structure. The support structure has a stepped cross-section and includes a module mounting part, a connecting part, and a bottom mounting part. The bottom mounting part and the fixing structure are detachably connected to fix the mounting bracket to the mounting surface.

[0008] Furthermore, the cross-section of the support structure can also be in the shape of an "I" shape, with the bottom mounting portion of the "I" shaped support structure distributed on both sides of the connection portion, resulting in higher stability.

[0014] Furthermore, the fixed structural components are provided with through reinforcing holes in the horizontal direction.

[0015] As an optional solution for the frame of the photovoltaic lightweight module mounting bracket, the width of the module mounting part, the height of the connecting part, and the width of the bottom mounting part are all within the range of 3-200mm.

[0017] As an optional solution for the frame of the photovoltaic lightweight module mounting bracket, the resin in the continuous fiber reinforced composite material is one or more of the following resins: polyurethane resin, unsaturated resin, epoxy resin, vinyl resin, etc.

[0018] The second objective of this utility model is to provide a photovoltaic lightweight module mounting bracket. After the photovoltaic lightweight module is installed on the bracket, the entire photovoltaic lightweight module can be moved in all directions by moving the bracket. It is easy to assemble and disassemble and does not affect the renovation or replacement of the color steel tile roof or other types of installation surfaces during use. At the same time, it can provide stable support for the photovoltaic lightweight module and improve the service life of the photovoltaic lightweight module.

[0019] To achieve this objective, the present invention also provides the following technical solution:

[0020] A photovoltaic lightweight module mounting bracket, wherein the mounting bracket is fixedly connected in a rectangular shape by the bracket frame described in any of the above embodiments, and the size and specifications of the mounting bracket are the same as those of the photovoltaic lightweight module to be installed.

[0021] Specifically, the fixed connection is provided with quick-connect holes on the connecting part.

[0038] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] like Figures 1 to 8 As shown, this embodiment provides a lightweight photovoltaic module mounting bracket frame. The bracket frame includes a support structure 13 and a fixing structure 7. The support structure 13 has a stepped cross-section and includes a module mounting part 1, a connecting part 4, and a bottom mounting part 5. The bottom mounting part 5 and the fixing structure 7 are detachably connected to fix the mounting bracket to the mounting surface 12.

[0041] Furthermore, the cross-section of the support structure 13 can also be in the shape of an "I". The bottom mounting part 15 of the "I" shaped support structure 13 is distributed on both sides of the connecting part 4, which makes the fixation of the photovoltaic lightweight module 10 more stable.

[0042] In the prior art, the photovoltaic lightweight module 10 is directly fixed to the mounting surface 12 using silicone or glue, which affects the replacement or renovation of the mounting surface 12. Alternatively, the photovoltaic lightweight module 10 can be installed on the mounting surface using a unidirectionally moving positioning seat or guide seat, but this still cannot solve the problem of flexible installation and easy replacement of the photovoltaic lightweight module 10.

[0043] To address the issue of flexible installation of the lightweight photovoltaic module 10, the photovoltaic lightweight module mounting bracket frame provided in this embodiment can be fixed to the mounting surface 12 by a detachable connection between the bottom mounting part 5 and the fixing structure 7. Especially for mounting surfaces of color steel tile type, the fixing part can be installed with the protruding part of the color steel tile, which facilitates construction and does not affect the overall structural stability of the color steel tile, thus avoiding further damage to the structure of the mounting surface.

[0044] As an optional solution for the frame of the photovoltaic lightweight module mounting bracket, glue is applied to the top of the module mounting part 1 to fix the photovoltaic lightweight module 10; and each side of the photovoltaic lightweight module 10 is fixed to the support structure 13 by the glue of the module mounting part 1 on the support structure 13 and then fixed to the mounting surface 12 by the fixing structure 7.

[0045] Furthermore, the component mounting section 1 is provided with interlocking grooves composed of reinforcing ribs 3 and adhesive application grooves 2;

[0046] The glue-applying groove 2 is designed to hold a sufficient amount of glue to ensure a tight bond between the photovoltaic lightweight module 10 and the module mounting part. The groove of the glue-applying groove 2 is designed to be wider at the top and narrower at the bottom, which saves glue usage while ensuring that the contact area between the photovoltaic lightweight module 10 and the glue is large enough. On the other hand, the reinforcing rib 3 has a structure that is narrower at the top and wider at the bottom, which can better enhance the support of the photovoltaic lightweight module 10.

[0047] Furthermore, one side of the component mounting part 1 is fixed to the photovoltaic lightweight component 10 with adhesive, and the other side is provided with an overflow groove 14 and an edge seal 15. The edge seal 15 is designed to provide waterproof protection for the component mounting part 1 and the photovoltaic lightweight component 10 fixed with adhesive, so as to avoid rainwater from having a negative impact on the installation of the photovoltaic lightweight component 10. The overflow groove 14 is also designed to facilitate construction by workers, so that sufficient adhesive can be used to fix the photovoltaic lightweight component during construction, without affecting other components due to excessive adhesive.

[0048] As an optional solution for the frame of a photovoltaic lightweight module mounting bracket, the bottom mounting part is fixed between the bottom mounting part and the fixing structure through the connection between the fixing structure and the mounting surface; the bottom mounting part is fixed by the pressure of the fixing structure on the bottom mounting part, and it is also convenient to adjust the position of the support structure during the installation process.

[0049] Furthermore, the bottom mounting part 5 and the fixing structure 7 are provided with matching grooves and protrusions, namely the upper positioning groove 6 and the lower positioning groove 7. The matching grooves and protrusions of the upper positioning groove 6 and the lower positioning groove 7 increase the friction between the bottom mounting part 5 and the fixing structure 7, improving the stability of their connection; moreover, this fixing method makes it easier for the photovoltaic lightweight module to be positioned along the direction of the groove / protrusion during installation.

[0050] Furthermore, in order to solve the problem of material usage in production, reduce the weight of the fixing structure 7, and improve the strength of the fixing structure 7, a through reinforcing hole in the horizontal direction is provided on the fixing structure 7.

[0051] As an optional solution for the frame of the photovoltaic lightweight module mounting bracket, the fixing structure 7 is provided with mounting holes 8. The fixing structure 7 is fixed to the bottom mounting part 5 using positioning grooves. The fixing structure 7 and the mounting surface 12 are connected by bolts 11 through the mounting holes 8. The bolt connection between the fixing structure 7 and the mounting surface 12, together with the upper positioning groove 6 and the lower positioning groove 7, can stably fix the support structure 13, which is fixedly connected to the photovoltaic lightweight module 10, to the mounting surface 12. When the user wants to separate the mounting surface 12 from the photovoltaic lightweight module 10, it is only necessary to unscrew the bolts 11. When it is necessary to continue to install the photovoltaic lightweight module 10 on a new mounting surface 12, it is only necessary to drill holes in the new mounting surface 12 and reinstall the fixing structure 7, which is fixed by the upper positioning groove 6 and the lower positioning groove 7, onto the new mounting surface 12 using bolts 11. The disassembly and reassembly of the photovoltaic lightweight module 10 is very convenient and the cost is extremely low.

[0052] As an optional solution for the frame of the photovoltaic lightweight module mounting bracket, the width of the module mounting part 1, the height of the connecting part 4, and the width of the bottom mounting part 5 are all within the range of 3-200mm. Setting the width of the module mounting part 1, the height of the connecting part 4, and the width of the bottom mounting part 5 within the above range can balance production costs and product performance requirements, ensuring stable support for the photovoltaic lightweight module 10 while minimizing waste of production costs.

[0053] As an alternative to the frame of a lightweight photovoltaic module mounting bracket, the bracket frame is made of continuous fiber reinforced composite material, wherein the continuous fibers are selected from one or more of glass fiber, basalt fiber, carbon fiber, hemp fiber, and polymer fiber. The use of continuous fibers can improve the strength of the bracket frame, especially for outdoor installations of lightweight photovoltaic modules, as it avoids stress concentration when subjected to impacts from gravel or sand, thus improving the stability of the mounting bracket.

[0054] As an optional solution for the frame of a lightweight photovoltaic module mounting bracket, the resin in the continuous fiber reinforced composite material is one or more resins selected from polyurethane resin, unsaturated resin, epoxy resin, vinyl ester resin, etc. Compared to other types of traditional materials, resin materials are lighter and easier to transport and install.

[0055] To achieve stable installation of lightweight photovoltaic modules, this embodiment provides a mounting bracket for lightweight photovoltaic modules. The mounting bracket is a rectangular structure fixedly connected to the bracket frame described in any of the above-mentioned schemes. The size and specifications of the mounting bracket are the same as those of the lightweight photovoltaic module to be installed. This minimizes the amount of bracket frame used while ensuring stable support for the lightweight photovoltaic module 10. Furthermore, it reduces transportation costs, allowing the mounting bracket frame to be directly transported to the installation location. The length of the mounting bracket frame can then be adjusted according to the specific specifications of the lightweight photovoltaic module 10 for installation, meeting the installation requirements of different specifications of lightweight photovoltaic modules 10.

[0056] Specifically, the fixed connection is provided with quick-connect holes on the connecting part. The size of the quick-connect holes is the same as the cross-section of the connecting part of the adjacent bracket frame, so that the two adjacent bracket frames can be quickly installed by plugging in the fixed method.

[0057] More specifically, limiting holes can be set at the connection part of the bracket frame. After the two adjacent bracket frames are quickly installed by plugging and fixing, the limiting pins are used to further fix the two adjacent bracket frames.

[0058] As an optional solution for the mounting bracket of the photovoltaic lightweight module, the fixing structure 7 has a lower positioning groove 6 distributed on one side and a mounting hole 8 provided on the other side; this arrangement can ensure the structural integrity of the support structure 13 on which the photovoltaic lightweight module 10 is fixed, and does not affect its mechanical performance after disassembly and reinstallation.

[0059] Furthermore, the fixing structure 7 has positioning grooves 6 on both sides and a mounting hole 8 in the middle. This design allows for the fixed installation of two closely spaced components, and also reduces the number of fixing structure 7 components used, thus lowering production costs.

[0060] As an optional solution for mounting brackets for lightweight photovoltaic modules, the mounting bracket can be arbitrarily fixed with a bracket frame in either the length or width direction. This is to prevent deformation of the middle position of the lightweight photovoltaic module 10 due to the lack of a support device, which would affect its service life. Furthermore, the above-mentioned reinforcement method allows for the reasonable addition of the mounting bracket frame, avoiding excessive support and waste.

The bottom mounting part 5 and the fixing structure 7 are detachably connected to fix the mounting bracket to the mounting surface 12.

[0063] The component mounting part 1 has a groove formed by the interlacing of reinforcing ribs 3 and glue application grooves 2 on one side, and the photovoltaic lightweight component 10 is fixed by applying glue in the glue application groove 2. The other side is provided with an overflow groove 14 and an edge sealing 15.

[0064] The bottom mounting part 5 has matching grooves and protruding positioning grooves above it and below it. It is then stably fixed between the bottom mounting part 5 and the fixed structure 7 through the connection between the fixed structure 7 and the mounting surface 12.

[0065] The component mounting part has a width of 20mm, the connecting part has a height of 20mm, and the bottom mounting part has a width of 25mm.

The mounting bracket is fixed to the mounting surface 12 using a fixing structure 7. A single application of adhesive is performed on the lightweight photovoltaic module 10 via an adhesive application groove 2 and reinforcing ribs 3 in the module mounting section 1, thus enabling the installation of the lightweight photovoltaic module 10. Furthermore, the mounting bracket has overflow grooves 14 and sealing edges 15 on all four sides to prevent moisture from entering the module, extending its service life. The lightweight photovoltaic module 10 can be moved and disassembled by removing the fixing components, facilitating the maintenance and replacement of the mounting surface 12.
