Description

Technical Field

[0001] The present invention relates to the field of photovoltaic technology, and in particular to a photovoltaic lightweight component mounting bracket frame and a mounting bracket. Background Art

[0002] Photovoltaic lightweight modules have the advantages of light weight and flexibility. They can be pasted on roofs, color steel tiles, walls and other building exteriors using structural adhesive. In particular, when installing photovoltaic lightweight modules on color steel tiles, the traditional installation method is to use a glue gun to apply structural adhesive to the ridges of the color steel tiles, and then lay the modules on the color steel tiles so that the back of the modules is bonded to the ridges of the color steel tiles with the structural adhesive. Although this installation method is simple and convenient to operate, it is inevitable that the color steel tile roof needs to be renovated or replaced during use, which requires the modules to be separated from the color steel tiles. The traditional installation method integrates the modules with the color steel tiles, making it difficult to separate the modules from the color steel tiles, and the modules are easily damaged during the separation process. In addition, the concave-convex structure of the color steel tiles causes the lightweight photovoltaic modules to be partially suspended. In the case of long-term lack of support, the modules are prone to deformation and other problems, which affects the power generation efficiency and service life of the modules.

[0003] CN219834021U discloses a lightweight flexible photovoltaic module quick disassembly and assembly bracket, including a positioning seat and a guide seat located between the convex edges of the color steel tile. The positioning seat cooperates with the guide seat, and although the assembly can be moved in the length direction of the positioning seat, the movement direction of the assembly is still greatly restricted, and it can only move in the direction set by the positioning seat during disassembly and assembly. Compared with the traditional installation method, although there is an improvement, it is still not sufficient.

[0004] Therefore, providing a photovoltaic lightweight component mounting bracket that can be easily disassembled and assembled and has a stable structure is a technical problem that needs to be urgently solved in the field. Summary of the invention

[0005] One of the purposes of the present invention is to propose a photovoltaic lightweight component mounting bracket frame, which can be fixedly installed according to the specifications and shapes of the photovoltaic lightweight components, so as to be suitable for the installation scenarios of photovoltaic lightweight components of various specifications, and the number of bracket frames can be adjusted according to the installer's usage requirements, thereby further improving the supporting force of the bracket on the photovoltaic lightweight components, thereby improving the stability of the photovoltaic lightweight components.

[0020] In order to make the technical problem solved by the present invention, the technical solution adopted and the technical effect achieved more clearly, the technical solution of the present invention is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0021] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figures 1 to 8 As shown, this embodiment provides a lightweight photovoltaic module mounting bracket frame, the bracket frame includes a supporting structure 13 and a fixing structure 7, the supporting structure 13 has a stepped cross-section, the supporting structure 13 includes a module mounting portion 1, a connecting portion 4 and a bottom mounting portion 5, the bottom mounting portion 5 and the fixing structure 7 are detachably connected to fix the mounting bracket to the mounting surface 12.

[0023] Furthermore, the cross section of the supporting structure 13 may also be in the shape of an I, and the bottom mounting portion 15 of the I-shaped supporting structure 13 is distributed on both sides of the connecting portion 4, so that the fixation of the photovoltaic lightweight component 10 is more stable.

[0024] In the prior art, the photovoltaic lightweight component 10 is directly fixed to the mounting surface 12 using silicone or glue, which affects the replacement or renovation of the mounting surface 12, or the photovoltaic lightweight component 10 is installed on the mounting surface through a unidirectionally movable positioning seat or guide seat, but the problem of flexible installation and easy replacement of the photovoltaic lightweight component 10 is still not solved.

[0025] In order to solve the problem of flexible installation of the photovoltaic lightweight component 10, the photovoltaic lightweight component mounting bracket frame provided in this embodiment can utilize the bottom mounting portion 5 and the fixed structural member 7 to fix the mounting bracket to the mounting surface 12 through a detachable connection. In particular, for the mounting surface of the color steel tile type, the fixing member and the raised part of the color steel tile can be installed, which is convenient for construction without affecting the stability of the overall structure of the color steel tile, thereby avoiding further damage to the structure of the mounting surface.

[0026] As an optional solution for the frame of the photovoltaic lightweight component mounting bracket, glue is applied on the top of the component mounting portion 1 to fix the photovoltaic lightweight component 10; and each side of the photovoltaic lightweight component 10 is fixed by glue on the component mounting portion 1 on the supporting structure 13 and stably installed on the supporting structure 13, and then installed on the mounting surface 12 through the fixing structure 7.

[0027] Furthermore, the component mounting portion 1 is provided with a concave-convex groove composed of reinforcing ribs 3 and glue coating grooves 2 interlaced; The setting of the glue coating groove 2 can accommodate a sufficient amount of glue to ensure the tight combination of the photovoltaic lightweight component 10 and the component mounting part, and the groove of the glue coating groove 2 is set to a shape that is wide at the top and narrow at the bottom, which saves the use of glue while ensuring that the contact area between the photovoltaic lightweight component 10 and the glue is large enough; on the other hand, the reinforcing rib 3 is a structure that is narrow at the top and wide at the bottom, which can better increase the supporting effect with the photovoltaic lightweight component 10.

[0028] Furthermore, one side of the component mounting portion 1 fixes the photovoltaic lightweight component 10 by glue, and the other side is provided with a glue overflow groove 14 and an edge seal 15; the design of the edge seal 15 can provide waterproof protection for the component mounting portion 1 and the photovoltaic lightweight component 10 fixed by glue, and prevent rain from having a negative impact on the installation of the photovoltaic lightweight component 10; and the design of the glue overflow groove 14 can also facilitate construction for workers, and during the construction process, the photovoltaic lightweight component can be fixed with sufficient glue without affecting other components due to excessive glue.

[0029] As an optional solution for the frame of the photovoltaic lightweight module mounting bracket, the bottom mounting part is fixed between the bottom mounting part and the fixed structure by connecting the fixed structure and the mounting surface; the bottom mounting part is fixed by the pressure of the fixed structure on the bottom mounting part, and it is convenient to support the position adjustment of the structure during the installation process.

[0030] Furthermore, the bottom surface mounting portion 5 and the fixed structure 7 are provided with upper positioning grooves 6 and lower positioning grooves 7 that can match each other. The upper positioning grooves 6 and lower positioning grooves 7 that match the grooves and protrusions increase the friction between the bottom surface mounting portion 5 and the fixed structure 7, and improve the stability of the connection between the two; and this fixing method makes it easier for the photovoltaic lightweight component to adjust its position along the direction of the grooves / protrusions during installation.

[0031] Furthermore, in order to solve the problem of production materials, reduce the weight of the fixed structure 7, and improve the strength of the fixed structure 7, the fixed structure 7 is provided with a through reinforcing hole in the horizontal direction.

[0032] As an optional solution for the frame of the photovoltaic lightweight component mounting bracket, the fixed structure 7 is provided with a mounting hole 8, and the fixed structure 7 is fixed to the bottom mounting portion 5 by means of the positioning groove, and the fixed structure 7 is connected to the mounting surface 12 by means of the bolt 11 through the mounting hole 8. The bolt connection between the fixed structure 7 and the mounting surface 12, in conjunction with the upper positioning groove 6 and the lower positioning groove 7, can stably fix the supporting structure 13 to which the photovoltaic lightweight component 10 is fixedly connected to the mounting surface 12, and when the user wants to separate the mounting surface 12 from the photovoltaic lightweight component 10, it is only necessary to unscrew the bolt 11, and when the photovoltaic lightweight component 10 needs to be installed on the new mounting surface 12, it is only necessary to drill holes on the new mounting surface 12 and re-install the fixed structure 7 fixed by the upper positioning groove 6 and the lower positioning groove 7 on the new mounting surface 12 by means of the bolt 11, and the disassembly and reassembly of the photovoltaic lightweight component 10 is very convenient and the cost is extremely low.

[0033] As an optional solution for the frame of the photovoltaic lightweight component mounting bracket, the width of the component mounting portion 1, the height of the connection portion 4, and the width of the bottom surface mounting portion 5 are all within the range of 3-200 mm. Setting the width of the component mounting portion 1, the height of the connection portion 4, and the width of the bottom surface mounting portion 5 within the above range can balance the production cost and product performance requirements, and on the basis of ensuring stable support for the photovoltaic lightweight component 10, the waste of production costs is avoided to the greatest extent.

[0034] As an optional solution for the frame of the photovoltaic lightweight module mounting bracket, the bracket frame is made of a continuous fiber reinforced composite material, wherein the continuous fiber is selected from one or more of glass fiber, basalt fiber, carbon fiber, hemp fiber and polymer fiber. The use of continuous fiber can improve the strength of the bracket frame, especially when the photovoltaic lightweight module mounting bracket is installed outdoors, it can avoid stress concentration when it is hit by gravel and sand, and improve the stability of the mounting bracket.

[0035] As an optional solution for the frame of the photovoltaic lightweight component mounting bracket, the resin in the continuous fiber reinforced composite material is one or more of polyurethane resin, unsaturated resin, epoxy resin, vinyl resin, etc. Compared with other types of traditional materials, the resin material is lighter and more convenient to transport and install.

[0036] In order to achieve stable installation of photovoltaic lightweight components, this embodiment provides a photovoltaic lightweight component mounting bracket, wherein the mounting bracket is fixedly connected to a rectangular shape by the bracket frame described in any of the above schemes, and the size of the mounting bracket is the same as the photovoltaic lightweight component to be installed. In this way, the use of the mounting bracket frame of the photovoltaic lightweight component 10 can be minimized while ensuring stable support for the photovoltaic lightweight component. In addition, the transportation cost can be reduced, and the mounting bracket frame can be directly transported to the installation location, and then the length of the mounting bracket frame can be adjusted according to the specific specifications of the photovoltaic lightweight component 10 for installation, so as to meet the installation requirements of photovoltaic lightweight components 10 of different specifications.

[0037] Specifically, the fixed connection is to open a quick-connect hole on the connection part, the size of the quick-connect hole is the same as the cross-section of the connection part of the adjacent bracket frame, so that two adjacent bracket frames can be quickly installed by plugging and fixing; More specifically, a limiting hole may be provided at the connection portion of the bracket frame, and after two adjacent bracket frames are quickly installed by plugging and fixing, the two adjacent bracket frames are further fixed by a limiting pin.

[0038] As an optional solution for the photovoltaic lightweight component installation bracket, the fixing structure 7 has a lower positioning groove 6 on one side and a mounting hole 8 on the other side. This arrangement can ensure the structural integrity of the supporting structure 13 fixed with the photovoltaic lightweight component 10 without affecting its mechanical properties after disassembly and reinstallation.

[0039] Furthermore, the fixing structure 7 has two lower positioning grooves 6 on both sides and a mounting hole 8 in the middle. This arrangement can realize the fixed installation of two components close to each other, and can reduce the number of fixing structure 7 used, thereby reducing production costs.

[0040] As an optional solution for the photovoltaic lightweight component mounting bracket, the mounting bracket can be fixedly installed with a bracket frame in the length direction or the width direction to avoid deformation of the middle position of the photovoltaic lightweight component 10 due to the lack of a supporting device, which affects the service life. In addition, the above reinforcement method can reasonably install the mounting bracket frame to avoid waste caused by too large a range of support.
