Description

Technical Field

[0001] This application relates to the field of solar energy technology, and in particular to a building-integrated solar photovoltaic device and its installation method. Background Technology

[0002] As a green and pollution-free renewable energy source, the development and utilization of solar energy has become a crucial technological field with decisive significance in the world's economic development in the 21st century. Building-integrated photovoltaics (BIPV) is a new concept for applying solar power generation, which simply means installing solar photovoltaic arrays on the roof of a building to provide electricity.

[0003] Regarding the aforementioned technologies, the applicant believes that currently, solar photovoltaic panels are installed on building roofs via brackets, and these panels are difficult to remove from the brackets. When damaged, replacing the panels is also quite troublesome, and there is still room for improvement. Summary of the Invention

[0004] To facilitate easier disassembly and replacement of damaged solar photovoltaic panels, this application provides a building-integrated solar photovoltaic device and its installation method.

[0005] The technical solution for the building-integrated solar photovoltaic (BIPV) device provided in this application is as follows: A building-integrated photovoltaic (BIPV) device includes a solar photovoltaic mechanism mounted on the main structure of a building. The solar photovoltaic mechanism includes a mounting base fixed to the roof of the main structure, an mounting plate, and solar photovoltaic wall panels. The mounting plate is fixed to the mounting base and has several support columns fixed to it. The solar photovoltaic wall panels are composed of several photovoltaic panels and supported by the support columns. Adjacent photovoltaic panels are detachably connected to the mounting plate via a connecting structure. The connecting structure includes a connecting bending rod movably connected to one photovoltaic panel and a fixed bending rod fixed to an adjacent photovoltaic panel. The bending points of the connecting bending rod and the fixed bending rod are opposite to each other, and their bent ends extend towards each other. The connecting bending rod extends to an adjacent photovoltaic panel and slides and inserts into the fixed bending rod for positioning.

[0006] By adopting the above technical solution, the support columns can provide an operational clearance for the installation and removal of photovoltaic panels. Adjacent photovoltaic panels are positioned by interlocking with connecting bending rods and fixed bending rods that are bent relative to each other and extend in opposite directions. After the connecting bending rods and fixed bending rods are interlocked, the adjacent photovoltaic panels are positioned in both the longitudinal and lateral directions. Disassembly can only be achieved when the connecting bending rod slides laterally to disengage from the fixed bending rod. This ensures connection stability on the one hand, and facilitates disassembly and replacement when the photovoltaic panel is damaged on the other hand.

[0007] Preferably, the connection structure further includes a drive rod for moving the connecting bending rod, the drive rod being slidably connected to the bottom of the photovoltaic panel, and a through groove with one end extending outwards for the drive rod to slide through the bottom of the photovoltaic panel; the connecting bending rod is fixed to the drive rod, and the drive rod extends to the edge near the photovoltaic panel, and the drive rod is positioned by a positioning structure.

[0008] By adopting the above technical solution, the drive rod can be pulled out of the photovoltaic panel through the through slot, avoiding the connecting bending rod from obstructing the disassembly of the photovoltaic panels relative to each other. The connecting bending rod is fixed to the drive rod, and the sliding process of the connecting bending rod relative to the fixed bending rod is controlled by the drive rod. The drive rod is further positioned by the positioning structure, making the relative fixed and detached states of the connecting bending rod and the fixed bending rod more stable, which is conducive to disassembly and assembly.

[0009] Preferably, the positioning structure includes a positioning rod and an abutment block movably connected within the drive rod. The positioning rod is connected by a connecting spring and housed within the drive rod, and the end of the positioning rod near the photovoltaic panel is bent to form a slider that can pass through the drive rod. The abutment block is made of deformable rubber material. When the abutment block is inserted into the end of the drive rod and abuts against the side wall of the positioning rod, the slider passes through the drive rod and is positioned on the photovoltaic panel by a locking structure.

[0010] By adopting the above technical solution, the positioning rod is housed inside the drive rod under the action of the connecting spring. The abutting block abuts, on the one hand, allowing the slider to pass through the drive rod, and on the other hand, keeping the slider in the state of passing through the outside, ensuring the connection between the drive rod and the photovoltaic panel. Furthermore, the locking structure further assists in the positioning of the slider.

[0011] Preferably, the bottom of the photovoltaic panel is provided with a groove for the slider to slide. When the slider slides to one end of the groove near the inside of the photovoltaic panel, the connecting bending rod is inserted into the fixed bending rod; when the slider slides to the other end of the groove, the connecting bending rod is separated from the fixed bending rod; the locking structure includes magnets fixed on the two opposite side walls of the slider and magnetic blocks fixed at both ends of the groove. When the slider slides to both ends of the groove, the magnets can be attracted and fixed with the corresponding magnetic blocks.

[0012] By adopting the above technical solution, the cooperation between the slider and the groove guides the sliding process of the drive rod on the one hand, and the magnetic positioning of the slider at both ends of the groove on the other hand makes it easier to control the connection and separation process of adjacent photovoltaic panels more accurately, while also making disassembly and assembly more convenient.

[0013] Preferably, each of the longitudinally adjacent photovoltaic panels has a fixing block at the oblique angle opposite to the corresponding drive rod, and the fixing blocks abut against the mounting plate; a connecting stud is provided on one fixing block, and the end of the connecting stud near the other fixing block is enlarged and threaded, and the other fixing block has a threaded opening for threaded connection of the connecting stud.

[0014] By adopting the above technical solution, the vertically adjacent photovoltaic panels are connected by relatively set fixing blocks. The end of the connecting stud is enlarged and can be preset on a fixing block. When it is necessary to fix the vertically adjacent photovoltaic panels, the connecting stud can be threaded to another fixing block. In this way, four photovoltaic panels that are adjacent in both the vertical and horizontal directions can be assembled and fixed. When damaged, they can be replaced uniformly without disassembling them one by one, which improves the convenience of replacement.

[0015] Preferably, the support columns are arranged opposite each other at two oblique angles of the photovoltaic panel and are respectively located at adjacent corners of the drive rod; a bonding plate that can be connected to the side wall of the support column is fixed on the photovoltaic panel, the bonding plate has an opening on one side, and the openings of the bonding plates on the horizontally adjacent photovoltaic panels are arranged facing each other; the support column is made of metal, and the bonding plate is made of magnetic material that can be magnetically fixed to the support column, and the bonding plate is attracted and tightly attached to the support column.

[0016] By adopting the above technical solution, the support column and drive rod are staggered to avoid mutual interference between structures, and the cooperation between the bonding plate and the support column further improves the installation stability of the photovoltaic panel; the openings of the bonding plates on the horizontally adjacent photovoltaic panels are set to face each other, so that two horizontally adjacent opposite photovoltaic panels can be disassembled by moving them back to back. When several solar photovoltaic wall panels are spliced ​​side by side, it is convenient to disassemble the photovoltaic panels located on both sides; at the same time, the bonding plate and the support column can also be separated by vertically disassembling the photovoltaic panel, which is convenient for disassembling the photovoltaic panel in the middle.

[0017] This application also provides an installation method for a building-integrated solar photovoltaic (BIPV) device, employing the following technical solution: An installation method for a building-integrated photovoltaic (BIPV) solar photovoltaic system includes the following steps: first, fixing the mounting base to the roof of the building; then fixing the mounting base with a pre-set support column on the mounting base; when installing the solar photovoltaic wall panel, first moving two horizontally adjacent photovoltaic panels towards each other so that the bonding plate at the bottom of the photovoltaic panel is attracted and fixed to the support column; at this time, the connecting bending rod on one photovoltaic panel extends to the position corresponding to the fixed bending rod on the horizontally adjacent photovoltaic panel. Then insert the abutment block into the drive rod so that the slide plate passes through the drive rod and is located at one end of the slide groove. Push the drive rod by hand to move it into the photovoltaic panel until the slide plate is magnetically attracted to the other end of the slide groove. Connect the bending rod and insert it into the fixed bending rod. By threading the connecting stud on one fixed block to another fixed block, the vertically adjacent photovoltaic panels can be connected.

[0018] In summary, this application includes at least one of the following beneficial technical effects: The support column provides an operating clearance for the installation and removal of photovoltaic panels. After the connecting bending rod and the fixed bending rod are inserted and positioned, the adjacent photovoltaic panels are positioned in both the longitudinal and lateral directions. This ensures the stability of the connection on the one hand, and on the other hand, if the photovoltaic panel is damaged, it can be slid laterally through the connecting bending rod to disengage from the fixed bending rod, so as to realize convenient disassembly and replacement operations. By controlling the drive rod to move the connecting bending rod relative to the fixed bending rod, the drive rod can be pulled out of the photovoltaic panel through the through slot, avoiding the connecting bending rod from obstructing the disassembly of the photovoltaic panel relative to the adjacent photovoltaic panel; at the same time, the drive rod can achieve accurate sliding positioning on the photovoltaic panel through the cooperation of the slider and the slide groove, which makes it easy for the operator to judge the insertion and separation of the connecting bending rod and the fixed bending rod, and realize convenient disassembly and assembly. The magnetic fixing of the bonding plate and the support column further improves the installation stability of the photovoltaic panel; the openings of the bonding plates on the horizontally adjacent photovoltaic panels are set to face each other, so that two horizontally adjacent opposite photovoltaic panels can be disassembled by moving them back to back. When several solar photovoltaic wall panels are spliced ​​side by side, it is convenient to disassemble the photovoltaic panels on both sides; at the same time, the bonding plate and the support column can also be separated by vertically disassembling the photovoltaic panels, which is convenient for disassembling the photovoltaic panels in the middle. Vertically adjacent photovoltaic panels are connected by relatively fixed blocks. The end of the connecting stud is enlarged and can be pre-set on a fixed block. When it is necessary to fix the vertically adjacent photovoltaic panels, the connecting stud can be threaded to another fixed block. In this way, four photovoltaic panels that are adjacent in both the vertical and horizontal directions can be assembled and fixed. When damaged, they can be replaced in a unified manner without disassembling them one by one, which improves the convenience of replacement. Attached Figure Description

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application discloses a building-integrated solar photovoltaic (BIPV) device, referring to... Figure 1 The solar photovoltaic system 1 is installed on the main body of the building. The solar photovoltaic system 1 includes a fixed base 11, an mounting plate 12 and a solar photovoltaic wall panel 13, which are fixed to the roof of the main body of the building. The mounting plate 12 is fixed on the fixed base 11 and a number of support columns 121 are fixed on the mounting plate 12. The solar photovoltaic wall panel 13 is composed of a number of photovoltaic panels 131 and is supported by the support columns 121.

[0023] Reference Figure 1 , 2 Adjacent photovoltaic panels 131 are detachably connected to the mounting plate 12 via a connecting structure 2. The connecting structure 2 includes a connecting bending rod 21 movably connected to a photovoltaic panel 131 and a fixed bending rod 22 fixed to an adjacent photovoltaic panel 131. The connecting bending rod 21 and the fixed bending rod 22 are located close to each other on one side of two horizontally adjacent photovoltaic panels 131. The bending points of the connecting bending rod 21 and the fixed bending rod 22 are arranged opposite to each other, and the bent ends of the connecting bending rod 21 and the fixed bending rod 22 extend towards each other.

[0024] Reference Figure 2 The connecting bending rod 21 extends to the adjacent photovoltaic panel 131 at the position corresponding to the fixed bending rod 22. The connecting bending rod 21 can be driven by hand to slide longitudinally and be inserted and positioned at the fixed bending rod 22.

[0025] Reference Figure 1 , 2 The connection structure 2 further includes a drive rod 23 for driving the bending rod 21 to move. The drive rod 23 is slidably connected to the bottom of the photovoltaic panel 131. The bottom of the photovoltaic panel 131 has a T-shaped through groove 3 with one end extending outward for the drive rod 23 to slide. The top of the drive rod 23 is fixed with a T-shaped block that matches the through groove 3 and is slidably connected to the through groove 3.

[0026] Reference Figure 2The connecting bending rod 21 is fixed to the driving rod 23, and the driving rod 23 extends to the edge near the photovoltaic panel 131 for easy manual driving. The driving rod 23 can be pulled out of the photovoltaic panel 131 through the through slot 3 to avoid the connecting bending rod 21 from obstructing the disassembly of the photovoltaic panel 131 relative to the adjacent photovoltaic panel 131; the driving rod 23 is positioned by the positioning structure 4.

[0027] Reference Figure 2 , 3 The positioning structure 4 includes a positioning rod 41 and an abutment block 42 movably connected within the drive rod 23. The positioning rod 41 is connected to and housed within the drive rod 23 via a connecting spring 5, and the end of the positioning rod 41 near the photovoltaic panel 131 is bent to form a slider 6 that can pass through the drive rod 23. The abutment block 42 is made of deformable rubber. When the abutment block 42 is inserted into the end of the drive rod 23 and abuts against the side wall of the positioning rod 41, the slider 6 passes through the drive rod 23. A protruding plate 8 is provided at the bottom of 31. A groove 81 is provided on the side wall of the protruding plate 8 for the slider 6 to be accommodated and slide. Under the action of the connecting spring 5, the positioning rod 41 is housed in the drive rod 23. The abutting block 42 abuts to allow the slider 6 to pass through the drive rod 23, and to keep the slider 6 in the state of passing through the outside, so as to ensure the connection between the drive rod 23 and the photovoltaic panel 131. The slider 6 is positioned in the groove 81 by the locking structure 7 to assist the positioning of the slider 6.

[0028] Reference Figure 2 , 3 When the slider 6 slides to one end of the slide groove 81 near the photovoltaic panel 131, the connecting bending rod 21 is inserted into the fixed bending rod 22; when the slider 6 slides to the other end of the slide groove 81, the connecting bending rod 21 separates from the fixed bending rod 22; the locking structure 7 includes magnets 71 fixed on the two opposite side walls of the slider 6 and magnetic blocks 72 fixed at both ends of the slide groove 81 respectively. When the slider 6 slides to both ends of the slide groove 81 respectively, the magnets 71 can be attracted and fixed with the corresponding magnetic blocks 72; the cooperation between the slider 6 and the slide groove 81 guides the sliding process of the drive rod 23 on the one hand, and the magnetic positioning of the slider 6 at both ends of the slide groove 81 on the other hand makes it easier to control the connection and separation process of adjacent photovoltaic panels 131 more accurately, and the disassembly and assembly are also more convenient.

[0029] Reference Figure 1 , 4 The support column 121 is positioned opposite each other at the two oblique angles of the photovoltaic panel 131 and is located at the adjacent corners of the drive rod 23. The support column 121 and the drive rod 23 are staggered to avoid mutual interference between the structures.

[0030] Reference Figure 4The bottom of the photovoltaic panel 131 is fixed with an adhesive plate 9 that can be connected to the side wall of the support column 121. The adhesive plate 9 has an opening on one side, and the openings of the adhesive plates 9 on the horizontally adjacent photovoltaic panels 131 are arranged facing each other, so that the two horizontally adjacent opposite photovoltaic panels 131 can be disassembled by moving them back to back. When several solar photovoltaic wall panels 13 are spliced ​​side by side, it is convenient to disassemble the photovoltaic panels 131 located on both sides.

[0031] Reference Figure 4 The support column 121 is made of metal, and the bonding plate 9 is made of magnet 71 material that can be magnetically fixed to the support column 121. The bonding plate 9 is attracted and tightly attached to the support column 121, which helps to improve the installation stability. The bonding plate 9 and the support column 121 can also be separated by vertically disassembling the photovoltaic panel 131, which facilitates the disassembly of the photovoltaic panel 131 in the middle.

[0032] Reference Figure 1 , 5 Each of the longitudinally adjacent photovoltaic panels 131 has a fixing block 10 fixed at an angle opposite to the corresponding drive rod 23. The fixing blocks 10 abut against the mounting plate 12 to assist in the stable installation of the photovoltaic panels 131. A connecting stud 101 is provided on one fixing block 10, and the end of the connecting stud 101 near the other fixing block 10 is enlarged and threaded. The other fixing block 10 has a threaded opening for the connecting stud 101 to be threaded. The longitudinally adjacent photovoltaic panels 131 are connected by the relatively arranged fixing blocks 10. The enlarged end of the connecting stud 101 can be preset on one fixing block 10. When it is necessary to fix the longitudinally adjacent photovoltaic panels 131, the connecting stud 101 can be threaded to the other fixing block 10. In this way, four photovoltaic panels 131 that are adjacent in both the longitudinal and transverse directions can be assembled and fixed. When damaged, they can be replaced uniformly without disassembling them one by one, which improves the convenience of replacement.

[0033] An installation method for a building-integrated solar photovoltaic (BIPV) device includes the following steps: First, fix the fixing base 11 to the roof of the main building, and then fix the mounting base with the pre-set support column 121 on the fixing base 11; when installing the solar photovoltaic wall panel 13, first move the two horizontally adjacent photovoltaic panels 131 towards each other so that the bonding plate 9 at the bottom of the photovoltaic panel 131 is correspondingly attracted and fixed to the support column 121. At this time, the connecting bending rod 21 on one photovoltaic panel 131 extends to the position corresponding to the fixed bending rod 22 on the horizontally adjacent photovoltaic panel 131. Then insert the abutment block 42 into the drive rod 23 so that the slide plate passes through the drive rod 23 and is located at one end of the slide groove 81. Push the drive rod 23 by hand to move it into the photovoltaic panel 131 until the slide plate is magnetically attracted to the other end of the slide groove 81. Connect the bending rod 21 and insert it into the fixed bending rod 22. The connecting stud 101 on one fixing block 10 is threaded onto another fixing block 10 to achieve the connection of longitudinally adjacent photovoltaic panels 131.
