Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic equipment, especially the frame members, photovoltaic modules and their installation structures. Background Art

[0002] In the current industrial building field, steel structure workshops have been widely used due to their significant advantages such as fast construction speed, high structural strength, and recyclability. With the continuous progress and development of renewable energy technologies, the application of photovoltaic modules on the facades of industrial buildings, especially steel structure workshops, has also increased day by day, becoming an important means to achieve the goals of green buildings and energy conservation and emission reduction.

[0003] However, during the installation process of photovoltaic modules on the facade, there are a series of technical problems to be solved urgently. First of all, the existing installation methods of photovoltaic modules on the facade basically adopt the same installation method as curtain walls, and usually have the following problems:

[0004] The installation of photovoltaic modules has higher requirements for sealing, and the treatment of the gaps between photovoltaic modules is a technical link that cannot be ignored. How to effectively prevent impurities such as rainwater and dust from entering the gaps, protect the electrical connection parts of the modules, extend the service life, and keep the facade clean and beautiful is a technical problem that needs to be solved urgently at present.

[0005] Photovoltaic panels are more fragile than other decorative panels and cannot be simply installed according to the installation method of traditional curtain walls. The installation method of traditional curtain walls will expose the sides of photovoltaic panels, which is not conducive to sealing and is likely to cause damage to photovoltaic panels in strong wind weather, affecting their normal power generation function and service life.

[0006] In addition, how to achieve rapid and accurate installation positioning of photovoltaic modules, improve the installation efficiency, and ensure the stability of the modules under harsh weather conditions is also a technical problem that needs to be solved urgently at present.

[0007] Therefore, we propose a new solution for frame members, photovoltaic modules and their installation structures, aiming to solve the above technical problems, improve the installation efficiency, stability and reliability of photovoltaic modules on the facade of steel structure workshops, and promote the wider application of photovoltaic technology in the industrial building field. Summary of the Invention

[0008] The applicant of the present invention aims at the above-mentioned disadvantages in the existing production technology and provides frame members, photovoltaic modules and their installation structures, thereby solving the technical problems such as insufficient flexibility, low installation efficiency, and difficult gap treatment existing in the traditional installation structure through innovative designs in multiple aspects such as a stable and scalable support frame design, rapid and accurate installation positioning and efficient installation process, and good sealing and maintenance convenience.

[0009] The technical solutions adopted by the present invention are as follows:

[0010] A frame member, comprising:

[0011] A first frame and a second frame, the two frames are used in combination and placed at both ends of an object to be fixed. Clamping openings for clamping the object to be fixed are provided on both of the two frames. At the same time, extension edges are provided on both of the two frames. The direction of the extension edge of one frame is the same as the opening direction of the clamping opening, and the direction of the extension edge of the other frame is opposite to the opening direction of the clamping opening.

[0012] As a further improvement of the above technical solution:

[0013] Both of the two frames include a support body. The clamping opening is provided at the lower end of one side of the support body, and the extension edge is provided at the other side of the support body.

[0014] On the frame where the direction of the extension edge is opposite to the opening direction of the clamping opening, openings are further provided on the extension edge of the frame.

[0015] A photovoltaic module, which includes a frame member as claimed in the claims, and further includes a photovoltaic panel. At least one frame member is provided on the photovoltaic panel. The photovoltaic panel is placed between the first frame and the second frame and is simultaneously connected to the clamping openings of the two frames.

[0016] An installation structure for installing the photovoltaic module as claimed in the claims, comprising:

[0017] Purlins, the number of which is multiple and are horizontally distributed;

[0018] Hangers, which are fixed on the purlins. The number of the hangers corresponds to the number of the frame members. Each group of hangers includes a first hanger and a second hanger. At least one of the first hanger and the second hanger is provided on each purlin. Slots with upward openings are provided on both the first hanger and the second hanger.

[0019] The extension edges of the first frame and the second frame on the photovoltaic module are respectively inserted into the slots provided on the first hanger and the second hanger.

[0020] In one embodiment, both the first hanger and the second hanger are fixed on the purlins by self-tapping screws. Only the first hanger is provided on the uppermost purlin, only the second hanger is provided on the lowermost purlin, both the first hanger and the second hanger are provided on the middle purlins, and the first hanger in the same group is located below the second hanger.

[0021] In one embodiment, the width of the first hanger is greater than the width of the second hanger, and mounting holes are provided on the second hanger. Fixing bolts for connecting the extension edge with the opening and the purlin together are provided on the mounting holes.

[0022] In one embodiment, it further includes:

[0023] Vertical decorative strip plates, with a plurality of them vertically and equidistantly spanning and distributed on a plurality of purlins.

[0024] In one embodiment, the number of the photovoltaic modules is a plurality and they are distributed in the area enclosed between the purlins and the vertical decorative strip plates.

[0025] In one embodiment, it further includes a horizontal decorative strip plate, which is located between two adjacent photovoltaic modules in the vertical direction, and the horizontal decorative strip plate is fixed together with the photovoltaic modules and the purlins through fixing bolts.

[0026] The beneficial effects of the present invention are as follows:

[0027] The structure of the present invention is compact, reasonable, and easy to operate. Through innovative designs in aspects such as a stable and scalable support frame design, quick and accurate installation positioning and efficient installation process, as well as good sealing and maintenance convenience, it solves the technical problems existing in traditional installation structures, such as insufficient flexibility, low installation efficiency, and difficult gap treatment. This installation structure not only improves the installation efficiency and stability of the photovoltaic modules, but also reduces the construction difficulty and maintenance cost, providing an efficient, reliable, and practical solution for the installation of facade photovoltaic modules in industrial building steel structure workshops.

[0028] Meanwhile, the present invention also has the following advantages:

[0029] Improve the strength of the photovoltaic modules: In this solution, multiple structures are connected together, significantly improving the strength of the photovoltaic modules. The ingenious design of the frame members is one of the key factors. Its first frame and second frame provide stable support for the photovoltaic panel through the support body, and the extension edges on the two frames are closely matched with the hanging parts, forming a solid connection structure. For example, the first frame is snap-fitted with the first hanging part, and the second frame is snap-fitted with the second hanging part. This snap-fitting method enhances the overall stability of the component. At the same time, a plurality of horizontally distributed purlins in the installation structure are fixed on the steel columns, providing a solid support foundation for the photovoltaic modules. A plurality of photovoltaic modules are distributed in the area enclosed by the purlins and the vertical decorative strip plates. The vertical decorative strip plates not only play a decorative role, but also limit the photovoltaic modules from flipping to the side away from the wall, further enhancing the strength of the components. The cooperation of these multiple structures enables the photovoltaic modules to maintain the integrity of the structure when facing various external forces, effectively resist the influence of bad weather, extend the service life of the photovoltaic modules, and ensure their long-term stable power generation.

[0030] Improve overall sealing performance: This solution effectively improves the overall sealing performance, which plays an important role in protecting the electrical connection parts of photovoltaic modules. The setting of the horizontal decorative strip is a key measure to improve the sealing performance. Its cross-section is in a "C" shape structure, and the three sides face two photovoltaic modules and the purlin respectively, which can effectively prevent impurities such as rainwater and dust from entering the gaps between photovoltaic modules. Install the horizontal decorative strip in the reserved gap between adjacent photovoltaic modules, and fix it to the photovoltaic module and the purlin through fixing bolts to form an integral module, greatly enhancing the sealing effect. In addition, a cover plate can be set on the horizontal decorative strip to seal the open side, further reducing the residual water accumulation and preventing impurities from entering. This good sealing performance not only protects the electrical connection parts of photovoltaic modules, avoids electrical failures caused by impurity erosion, extends the service life of the modules, but also keeps the facade clean and beautiful, improves the overall image of industrial buildings, and provides a strong guarantee for the stable operation of photovoltaic modules.

[0031] More convenient and fast installation and disassembly: The installation and disassembly process of this solution is more convenient and fast, greatly improving the construction efficiency. In terms of installation, the bayonet design of the frame member realizes the quick and firm connection between the photovoltaic panel and the frame, without additional fasteners, simplifying the installation process. At the same time, the slot design on the first hanging piece and the second hanging piece enables the outer extension edge of the frame of the photovoltaic module to be easily inserted, realizing quick and accurate installation positioning. The installation steps are clear. First, determine the positions of the purlin and the vertical decorative strip and install them, then install the hanging pieces, then insert the outer extension edge of the frame of the photovoltaic module into the slot, and finally install and fix the horizontal decorative strip. The whole process is efficient and orderly. In terms of disassembly, the overall disassembly process is opposite to the installation steps. When performing partial disassembly, only need to remove the fixing bolts on the horizontal decorative strip, move the photovoltaic module upward a small distance to get out of the restriction of the hanging piece slot, and then move it horizontally away from the purlin. Due to the reasonable thickness design of the vertical decorative strip, the photovoltaic module to be disassembled can move vertically after moving horizontally for a certain distance, thus facilitating partial disassembly. This convenient and fast installation and disassembly method reduces the construction difficulty and cost, and provides convenience for later maintenance and replacement.

[0040] The following will describe the specific embodiments of the present invention with reference to the accompanying drawings.

[0041] Embodiment 1

[0042] As Figure 4 shown, this embodiment provides a frame member, including a first frame 401 and a second frame 402. The two frames are used in combination and placed at both ends of an object to be fixed (such as a photovoltaic panel 403). Bayonets 4001 for clamping the object to be fixed are provided on both frames, and extension edges 4003 are provided on both frames. Among them, the direction of the extension edge 4003 of the first frame 401 is the same as the opening direction of the bayonet 4001, and the direction of the extension edge 4003 of the second frame 402 is opposite to the opening direction of the bayonet 4001.

[0043] Specifically, both frames include a support body 4002. The bayonet 4001 is provided at the lower end of one side of the support body 4002, and the extension edge 4003 is provided on the other side of the support body 4002. An opening is further provided on the extension edge 4003 of the second frame 402 to facilitate connection or fixation with other components.

[0044] The setting of the bayonet 4001 realizes the rapid and firm connection between the photovoltaic panel 403 and the frame, without the need for additional fasteners, simplifying the installation process. The first frame 401 and the second frame 402 are provided with extension edges 4003 with opposite directions at the other end of the support body 4002, which is to adapt to the different slot directions of the first hanging part 200 and the second hanging part 300, ensuring the flexibility and accuracy of the photovoltaic module 400 during the installation process. This frame design not only improves the installation efficiency of the photovoltaic module 400, but also enhances its structural strength and weather resistance.

[0045] Embodiment 2

[0046] This embodiment provides a photovoltaic module 400, which at least includes a kind of frame member in Embodiment 1, and also includes a photovoltaic panel 403. In one photovoltaic module 400 of this embodiment, there are at least two frame members, that is, two first frames 401 and two second frames 402. The two first frames 401 are located at the upper end of the photovoltaic panel 403 and are spaced apart. The two second frames 402 are located at the lower end of the photovoltaic panel 403 and are spaced apart. The photovoltaic panel 403 is placed between the first frame 401 and the second frame 402 and is simultaneously connected to the bayonets 4001 of the two frames, realizing the rapid and firm installation of the photovoltaic panel 403.

[0047] Specifically, the edge of the photovoltaic panel 403 is clamped in the bayonets 4001 of the first frame 401 and the second frame 402, and stable support is provided by the support body 4002 of the frame member. The outer extension edges 4003 of the first frame 401 and the second frame 402 are designed such that the photovoltaic module 400 can be conveniently connected to other installation structures (such as hanging parts).

[0048] Embodiment 3

[0049] As Figures 1 - 4 shown, this embodiment provides an installation structure for realizing the installation of the photovoltaic module 400 on a facade. The installation structure includes a plurality of horizontally distributed purlins 100 and a plurality of vertical decorative strip plates 600 that are evenly spaced and span across the plurality of purlins 100. The number of photovoltaic modules 400 is multiple and they are distributed in the area enclosed between the purlins 100 and the vertical decorative strip plates 600. In addition, the installation structure further includes hanging parts, and the hanging parts include a first hanging part 200 and a second hanging part 300. At least one or more of the first hanging part 200 and the second hanging part 300 are provided on each purlin 100, and upward-opening slots are provided on both the first hanging part 200 and the second hanging part 300. The photovoltaic module 400 includes a photovoltaic panel 403 and frames provided at the upper and lower ends of the photovoltaic panel 403, and outer extension edges 4003 inserted into the slots are provided on the frames.

[0050] The design of the installation structure in this embodiment fully considers the facade characteristics of industrial building steel structure workshops. Through multiple horizontally distributed purlins 100 and vertically equally spaced and spanning longitudinal decorative strip plates 600, a stable and expandable support framework is formed. At the same time, multiple horizontally arranged purlins 100 are fixed on the steel columns 700, improving the overall support strength. The photovoltaic modules 400 are arranged within this framework, ensuring both sufficient light contact area and facilitating maintenance and management. The first hanging parts 200 and the second hanging parts 300 not only provide connection interfaces between the photovoltaic modules 400 and the purlins 100, but also achieve quick and accurate installation positioning through the slots thereon. This slot design not only simplifies the installation process but also improves the flexibility and reliability of installation. The frame design of the photovoltaic modules 400 further enhances its structural strength. At the same time, the setting of the extension edge 4003 enables the photovoltaic modules 400 to be firmly inserted into the slots of the first hanging parts 200 and the second hanging parts 300, ensuring the stability of the modules under harsh weather conditions.

[0051] Specifically, as Figure 1 and Figure 2 shown, both the first hanging parts 200 and the second hanging parts 300 in this embodiment are fixed on the purlins 100 by self-tapping screws 301. Only the first hanging parts 200 are provided on the uppermost purlin 100, which is to facilitate the sequential installation of the photovoltaic modules 400 from top to bottom and avoid the problem of water accumulation at the top. Only the second hanging parts 300 are provided on the lowermost purlin 100, which is to provide additional support points to ensure the stability of the photovoltaic modules 400 under the action of gravity. Both the first hanging parts 200 and the second hanging parts 300 are provided on the intermediate purlins 100, and the first hanging parts 200 of the same group are located at the lower end of the second hanging parts 300. This design helps to guide rainwater to flow down smoothly, reducing the risk of water accumulation and maintaining the neat and beautiful facade at the same time. The width of the first hanging parts 200 is greater than that of the second hanging parts 300, which is to provide a larger contact area, enhance the support force at the upper end of the photovoltaic modules 400, and facilitate the adjustment of the horizontal position of the modules. Installation holes b are provided on the second hanging parts 300, and fixing bolts 302 for connecting the photovoltaic modules 400 and the purlins 100 are provided on the installation holes b, realizing the rigid connection between the photovoltaic modules 400 and the purlins 100 and ensuring the stability of the modules under the action of external forces such as wind load and snow load. This design not only improves the overall wind pressure resistance of the installation structure but also facilitates later maintenance and replacement, reducing the maintenance cost.

[0052] As Figure 1 and Figure 2As shown, in this embodiment, the first frame 401 is snap-fitted with the first hanging member 200, and the second frame 402 is snap-fitted with the second hanging member 300. At the same time, in this embodiment, the width of the first hanging member 200 is twice or more than the width of the second hanging member 300, and the number of the first frames 401 is more than the number of the second frames 402, which can greatly improve the supporting effect of the first frame 401 and the first hanging member 200. Since there is no other connection between the first hanging member 200 and the frame, by adopting the wider first hanging member 200 and more first frames 401, the overall supporting force can be improved.

[0053] In another embodiment, the number of the first hanging members 200 on a photovoltaic module 400 is one, and the width of the first hanging member 200 is 50%-80% of the length of the photovoltaic panel. The photovoltaic module 400 is snap-fitted on the first hanging member 200 through the first frame 401, and at the same time, it can also be translated left and right, which is convenient for the bolt connection of the second hanging member 300.

[0054] A gap is reserved between two adjacent photovoltaic modules 400 in the vertical direction, and the distance of the gap is greater than the height of the hanging member slot, which is convenient for the photovoltaic module 400 to be inserted into the slot of the hanging member for installation.

[0055] At the same time, a horizontal decorative strip 500 is arranged in the reserved gap, and the horizontal decorative strip 500 is fixed together with the photovoltaic module 400 and the purlin 100 through the fixing bolt 302, so that a whole module is formed among the photovoltaic module 400, the horizontal decorative strip 500, the second hanging member 300 and the purlin 100. At the same time, the adjacent two photovoltaic modules 400 are tightly connected through the horizontal decorative strip 500, and then the whole photovoltaic module 400 forms a whole.

[0056] In this embodiment, the cross-section of the horizontal decorative strip 500 is in a "C" shape structure, and its three sides face the two photovoltaic modules 400 and the purlin 100 respectively. The arrangement of the horizontal decorative strip 500 effectively prevents impurities such as rainwater and dust from entering the gap between the photovoltaic modules 400, protects the electrical connection part of the module, and extends the service life. At the same time, the horizontal decorative strip 500 is connected with the photovoltaic module 400 and the purlin 100 through the fixing bolt 302, which enhances the stability of the overall structure and prevents the modules from colliding or shifting with each other due to the action of wind force. This design not only improves the sealing performance of the installation structure, but also beautifies the facade appearance and improves the overall image of the industrial building.

[0057] In another embodiment, a cover plate is also arranged on the horizontal decorative strip 500, which can seal the open side of the horizontal decorative strip 500, make the facade of the whole photovoltaic module 400 more flat, reduce the residual water accumulation, and in addition, electronic components can also be placed in the horizontal decorative strip 500.

[0058] The cross-section of the longitudinal decorative strip 600 is in a "ji" shape, and its two outwardly extending sides can limit the photovoltaic module 400 from flipping away from the wall. At the same time, the thickness of the longitudinal decorative strip 600, that is, the horizontal distance, is ≥ 2 times the thickness of the photovoltaic module 400 + the thickness of the hanging part. Thus, after the photovoltaic module 400 breaks away from the restriction of the hanging part, it can move upward or downward, facilitating subsequent maintenance.

[0059] The U-shaped design of the longitudinal decorative strip 600 not only reduces the structural weight but also improves its resistance to bending and torsion, enhancing the stability of the overall structure. The setting of the sealing plate effectively prevents impurities such as rainwater and dust from entering the interior of the longitudinal decorative strip 600, protecting its internal structure and extending its service life. At the same time, the design of the sealing plate extending to both sides increases the contact area between the longitudinal decorative strip 600 and the purlin 100, enhancing the firmness of the connection point. This design of the longitudinal decorative strip 600 not only improves the bearing capacity and weather resistance of the installation structure but also simplifies the installation process and reduces the construction difficulty.

[0060] In another embodiment, a walking robot is provided inside the transverse decorative strip 500 or the longitudinal decorative strip 600, and a cleaning reel is arranged between two adjacent walking robots, enabling the surface cleaning of the photovoltaic panel 403. At the same time, according to the moving direction of the selected robot, the decorative strip in the corresponding direction is designed to span one row or one column, facilitating the cleaning of an entire row or an entire column of photovoltaic panels 403. Meanwhile, for the convenience of the movement of the walking robot, a rack can be arranged inside the decorative strip, and a gear is arranged on the walking robot to achieve vertical movement. Additionally, to prevent the walking robot from falling, baffles are also arranged inside the transverse decorative strip 500 and the longitudinal decorative strip 600, with the baffles facing the inner side of the decorative strip, as Figure 3 shown.

[0061] Multiple self-tapping screw 301 mounting holes are provided on the first hanging part 200, providing greater installation flexibility and meeting the installation requirements of photovoltaic modules 400 with different sizes and specifications. At the same time, the selection of multiple holes can also disperse stress, enhancing the connection strength between the first hanging part 200 and the purlin 100. This design not only improves the adaptability and reliability of the installation structure but also simplifies the installation process, reducing the construction difficulty and cost. The width of the photovoltaic module 400 is infinitely close to the distance between two adjacent longitudinal decorative strips 600, and the width of the photovoltaic module 400 is greater than the distance between two adjacent sealing plates on the two adjacent longitudinal decorative strips 600 that are close to each other, which can limit the outward flipping and falling of the photovoltaic module 400. At the same time, the two longitudinal decorative strips 600 can limit the left and right movement of the installed photovoltaic module 400, and the hanging part can limit the up and down movement of the installed photovoltaic module 400.

[0062] A water baffle is provided at the upper end of the purlin 100 at the uppermost end, effectively preventing rainwater from seeping into the building interior from the top of the facade and protecting the safety and stability of the building structure.

[0063] The number of the second hangers 300 connected to the same photovoltaic module 400 is at least two, providing a larger support area and stability, ensuring the firmness of the photovoltaic module 400 under the action of gravity. At the same time, the scattered arrangement of multiple second hangers 300 can also disperse stress and enhance the connection strength between the module and the purlin 100. This design not only improves the bearing capacity and stability of the installation structure, but also simplifies the installation process, reduces the construction difficulty and cost. In addition, the design of multiple second hangers 300 also provides a larger operation space for later maintenance and replacement, facilitating quick and accurate maintenance and replacement operations by maintenance personnel.

[0064] The specific installation steps in this embodiment are as follows:

[0065] First, according to the size of the photovoltaic module 400, determine the positions of the purlin 100 and the longitudinal decorative strip 600 on the facade of the steel structure factory building and install them. Ensure that the purlin 100 is horizontally distributed, and the longitudinal decorative strips 6 are vertically and equally spaced across the purlin. Then, install the first hanger 200 and the second hanger 300 on the purlin 100.

[0066] Insert the extension edges 4003 on the frame of the photovoltaic module 400 into the slots of the first hanger 200 and the second hanger 300 respectively to achieve quick and accurate installation positioning.

[0067] Align the second frame 402 with the mounting hole b of the second hanger 300. Install the horizontal decorative strip 500 between two adjacent photovoltaic modules 400 in the vertical direction, and use the fixing bolt 302 to fix the second hanger 300, the horizontal decorative strip 500, the photovoltaic module 400 and the purlin 100 together to ensure tightness and stability. Finally, check whether all connection points are firm to ensure the safety and stability of the installation structure. Make adjustments and reinforcements if necessary.

[0068] In addition, for the convenience of aligning the mounting hole b, the longitudinal decorative strip 600 can also be installed last.

[0069] In this embodiment, the specific disassembly steps are as follows:

[0070] The overall disassembly process is opposite to the installation steps and will not be elaborated here.

[0071] The disassembly of a local photovoltaic module 400 includes the following steps:

[0072] Remove the fixing bolts 302 in the two horizontal decorative strip plates 500 above and below the photovoltaic module 400 to be disassembled. At this time, remove the corresponding horizontal decorative strip plates 500, move the photovoltaic module 400 upward a small distance to disengage from the restriction of the hanging slot, and then move it horizontally away from the purlin 100. Since the thickness of the vertical decorative strip plate 600 ≥ 2 * the thickness of the photovoltaic module 400 + the thickness of the hanging part, the photovoltaic module 400 to be disassembled can achieve vertical movement after moving horizontally for a certain distance, so as to carry out partial disassembly.

[0073] In this embodiment, it should be noted that the wiring of the photovoltaic module 400 can be set on the side of the photovoltaic module 400 close to the facade or in the horizontal decorative strip plate 500. If it is set on the facade side, the wire harness needs to be extended at this time to facilitate installation and disassembly.
