Description

Technical Field

[0001] This application relates to the technical field of building integrated photovoltaics, and particularly to an installation device for photovoltaic modules and a photovoltaic system thereof. Background Art

[0002] Building Integrated Photovoltaic (BIPV) uses photovoltaic modules as building components or building materials, making them part of the building and having the function of generating electricity at the same time. BIPV can avoid occupying too much land resources, which is particularly important for urban buildings with expensive land. BIPV converts solar energy into electrical energy, which can reduce the comprehensive outdoor temperature and play a role in peak shaving for the power grid, achieving the effect of building energy conservation.

[0003] In related technologies, photovoltaic modules are fixedly installed on a shed by means of segmented arrangement of aluminum alloy pressing blocks. Without setting aluminum alloy wire pressing, rainwater may flow through the gaps between photovoltaic modules to the lower part of the shed, wetting the vehicles. Under the condition of setting aluminum alloy wire pressing when it rains, although it can play a role in drainage, there are many accessories and the construction is relatively complicated. In extreme weather with heavy rainfall such as rainstorms and typhoons, there may be a hidden danger of water leakage. Summary of the Invention

[0040] Figure 1 Schematic diagram of the installation device of a photovoltaic module according to some embodiments of the present application fixed to a purlin.

[0041] One or more embodiments of the present application disclose an installation device for a photovoltaic module. Referring to Figures 1 - 4 , the installation device of the photovoltaic module includes a base 10 and a seal. The base 10 includes a base body 11, a main body section 12 and a placement section 112 of the base body 11. The placement section 112 is fixedly connected to the purlin 80. The main body section 12 is used to support the photovoltaic module 60. First receiving surfaces 122 and second receiving surfaces 123 are provided on both sides of the main body section 12. The seal extends integrally or separately from the main body section 12 into the installation gap 90 between adjacent photovoltaic modules 60. The first receiving surface 122 and the second receiving surface 123 are respectively located on both sides of the seal. The first receiving surface 122 is fixedly connected to the photovoltaic module 60 on one side, and the second receiving surface 123 is fixedly connected to the photovoltaic module 60 on the other side, so that the seal can seal the installation gap 90 between adjacent photovoltaic modules 60.

[0042] That is to say, the base 10 is used to support and connect two adjacent photovoltaic modules 60. The seal divides the main body section 12 into a first receiving surface 122 and a second receiving surface 123. The first receiving surface 122 is used to support and fix the side of one of the photovoltaic modules 60, and the second receiving surface 123 is used to support and fix the side of the other photovoltaic module 60. Further, the bases 10 are arranged at intervals along the extension direction of the purlin 80, so that the photovoltaic modules 60 can be installed on the purlin 80 to cover the top surface of the carport.

[0043] It can be understood that by placing a seal in the installation gap 90 between adjacent photovoltaic modules 60, it is beneficial to prevent rainwater from flowing from the installation gap 90 between the photovoltaic modules 60 to the lower part of the photovoltaic modules 60, thus playing a good waterproof role. And the base 10 can be pre-fixed to the installation frame 50 of the photovoltaic module 60, and then the base 10 is fixed to the purlin 80, which is beneficial to reduce the time of working at heights and improve the construction efficiency and construction safety.

[0044] Specifically, asFigures 1 - 4 As shown, the base body 11 further includes a support section 113. The support section 113 is used to connect the two ends of the main body section 12 and the placement section 112, so that the main body section 12 and the placement section 112 are arranged at intervals relative to each other. A cavity 111 is defined between the main body section 12, the support section 113 and the placement section 112. It is worth mentioning that the cavity 111 is used to accommodate the wiring and connectors of the photovoltaic module 60, so that the wiring is more regular and concealed, improving the aesthetics of the carport. At the same time, the base 10 can protect the wiring and connectors of the photovoltaic module 60, which is beneficial to avoiding the wiring and connectors from being exposed to the sun and eroded, and thus the service life of the wiring and connectors can be extended, and the reliability of the photovoltaic system can be improved. In at least one embodiment, the height of the support section 113 is greater than 2.5 cm, so as to facilitate the placement of the connector in the cavity 111.

[0045] In some embodiments, as Figures 2 - 4 shown, the main body section 12 has through holes 121 suitable for fasteners to pass through. The through holes 121 are arranged opposite to the placement section 112, so that the fasteners can pass through the through holes 121 and be fixedly connected to the placement section 112. That is to say, when the base 10 is placed on the purlin 80, the through holes 121 on the main body section 12 allow the fasteners and installation tools (such as screwdrivers) to pass through, facilitating the installation operation of the construction personnel. Then, the fasteners can connect the placement section 112 and the purlin 80, so that the base 10 is fixed on the purlin 80. It is worth mentioning that, as Figure 1 shown, when the fastener is installed on the placement section 112, the head of the fastener is accommodated in the cavity 111 between the main body section 12 and the placement section 112. Then, the base 10 can shield the head of the fastener, which is beneficial to improving the aesthetics of the carport and extending the service life of the fastener.

[0046] In at least one embodiment, as Figure 1 shown, when the photovoltaic module 60 is installed on the base 10, the installation frame 50 of the photovoltaic module 60 covers the through holes 121 on the main body section 12, which is beneficial to preventing rainwater from entering the cavity 111 through the through holes 121, and further improving the waterproof performance of the installation device of the photovoltaic module.

[0047] In at least one embodiment, as Figures 2 - 4 shown, the through holes 121 are long holes. When the base 10 is placed on the purlin 80, the extending direction of the long holes is perpendicular to the extending direction of the purlin 80, that is, the extending direction of the long holes is parallel to the width direction of the purlin 80, so as to facilitate the adjustment of the position of the fasteners during the installation process, making the fasteners as close as possible to the middle position in the width direction of the purlin 80.

[0048] In at least one embodiment, the base 10 and the purlin 80 are fixed by stainless steel self-tapping screws, which is convenient for adjusting the position of the stainless steel self-tapping screws relative to the purlin 80 and is conducive to improving the construction efficiency.

[0049] In some embodiments, as Figure 2 shown, the base 10 further includes at least one extension segment 13, and the extension segment 13 integrally extends from one or both sides of the main body segment 12 toward the photovoltaic module 60. The extension segment 13 can extend the first receiving surface 122 and / or the second receiving surface 123, so as to increase the contact area between the base 10 and the photovoltaic module 60, improve the load-bearing capacity of the base 10, and further contribute to improving the structural reliability of the installation device of the photovoltaic module.

[0050] In some embodiments, as Figure 2 shown, the extension segment 13 has mounting holes 131 adapted to fasteners, so that the pressing block 20 can be fixedly connected to the extension segment 13 through the fasteners. It can be understood that, compared with setting the mounting holes 131 on the main body segment 12, in this embodiment, the extension segment 13 extends from the main body segment 12 toward the photovoltaic module 60 and can be located outside the base body 11. Further, the extension segment 13 and the placement segment 112 are arranged in a staggered manner, and the mounting holes 131 are arranged on the extension segment 13, which is conducive to avoiding interference between the fasteners and the installation tools and the placement segment 112 and the support segment 113 during the installation process, and improving the convenience of the installation operation. Moreover, when the photovoltaic module 60 is installed on the base 10, the photovoltaic module 60 can shield the extension segment 13, that is to say, the fasteners can be hidden under the photovoltaic module 60, which is conducive to keeping the top surface of the shed clean and improving the aesthetics of the shed.

[0051] In at least one embodiment, as Figure 2 shown, the mounting holes 131 are clearance holes, and the mounting frame 50 of the photovoltaic module 60 also has a clearance hole. When the photovoltaic module 60 is installed on the base 10, the mounting holes 131 and the clearance holes on the mounting frame 50 are arranged opposite to each other. Then, bolts can pass through the mounting holes 131 and the clearance holes on the mounting frame 50 and be tightened through the thread fit of the nuts and bolts, so that the photovoltaic module 60 is detachably installed on the base 10. The operation is simple, which is conducive to improving the installation efficiency, and is also convenient for subsequent disassembly and replacement of the photovoltaic module 60, which is conducive to improving the maintainability of the shed. It is worth mentioning that the mounting holes 131 can also be threaded holes, and the present application does not make specific limitations thereto.

[0052] In some embodiments, as Figure 2As shown, the mounting device of the photovoltaic module further includes a pressing block 20. The pressing block 20 includes a pressing section 21 and an abutting section 22. The abutting section 22 extends from one end of the pressing section 21 towards the base 10. When the pressing block 20 is fixedly connected to the base 10, the abutting section 22 abuts against the first receiving surface 122 or the second receiving surface 123, and one end of the pressing section 21 away from the abutting section 22 abuts against the mounting frame 50 of the photovoltaic module 60, so that the mounting frame 50 of the photovoltaic module 60 is clamped between the pressing section 21 and the first receiving surface 122, or clamped between the pressing section 21 and the second receiving surface 123.

[0053] In some embodiments, as Figure 2 and Figure 5 shown, a connection hole 212 is provided on the pressing section 21. When the photovoltaic module 60 is mounted on the base 10, the connection hole 212 is disposed opposite to the mounting hole 131 on the extension section 13. Then, a fastener can pass through the connection hole 212 on the pressing section 21 and the mounting hole 131 on the extension section 13, so that the pressing block 20 is fixed to the base 10. Specifically, one end of the pressing block 20 abuts against the first receiving surface 122 or the second receiving surface 123 of the base 10 through the abutting section 22, and the other end of the pressing block 20 elastically presses against the mounting frame 50 of the photovoltaic module 60, so that the mounting frame 50 of the photovoltaic module 60 is clamped between the pressing block 20 and the base 10.

[0054] In at least one embodiment, as Figure 2 shown, the mounting hole 131 on the extension section 13 is a light hole, and the connection hole 212 on the pressing section 21 is a threaded hole. Then, a bolt can pass through the mounting hole 131 on the extension section 13 and be threadedly engaged and tightened with the connection hole 212 on the pressing section 21, so that the photovoltaic module 60 is detachably mounted on the base 10. The operation is simple, which is beneficial to improving the installation efficiency, and is also convenient for subsequent disassembly and replacement of the photovoltaic module 60, which is beneficial to improving the maintainability of the shed. It is worth mentioning that the connection hole 212 can also be a light hole, and the present application does not make specific restrictions on this.

[0055] In at least one embodiment, as Figure 2 and Figure 5 shown, a protrusion 211 is further provided on the pressing section 21. The protrusion 211 is located on the periphery of the connection hole 212, and the protruding direction of the protrusion 211 is the same as the extending direction of the connection hole 212. Then, the thickness of the pressing section 21 in the extending direction of the connection hole 212 can be increased through the protrusion 211, which is beneficial to extending the screwing length of the fastener and the pressing section 21, and further beneficial to improving the connection strength between the pressing block 20 and the base 10.

[0056] In at least one embodiment, as Figures 1 - 4As shown, the extension section 13 includes a first extension section 132 and a second extension section 133. The first extension section 132 and the second extension section 133 extend from opposite sides of the main body section 12 in directions away from each other, thereby extending the first receiving surface 122 and the second receiving surface 123. Further, mounting holes 131 are provided on both the first extension section 132 and the second extension section 133. Mounting frames 50 are provided on opposite sides of the photovoltaic module 60. One of the mounting frames 50 is connected to the first extension section 132 through a pressing block 20, so that one side of the photovoltaic module 60 is fixedly supported on the first receiving surface 122, and the other mounting frame 50 is connected to the second extension section 133 through bolts and nuts, so that the other side of the photovoltaic module 60 is fixedly supported on the second receiving surface 123.

[0057] In some embodiments, as Figure 2 and Figure 6 shown, the seal includes a sealing strip 30. The sealing strip 30 includes an adhesive section 31, an upper sealing portion 32, and a lower sealing portion 33. The adhesive section 31 is adhered to the back surface of the mounting frame 50 of one of the photovoltaic modules 60. The upper sealing portion 32 and the lower sealing portion 33 extend deformably from the adhesive section 31 toward the back surface of the mounting frame 50 of the other photovoltaic module 60, and the upper sealing portion 32 is located above the lower sealing portion 33. It can be understood that under the condition that the sealing strip 30 is installed in the installation gap 90 between adjacent photovoltaic modules 60, the upper sealing portion 32 and / or the lower sealing portion 33 are squeezed by the mounting frame 50 of the photovoltaic module 60, and then elastically deformed, so that the sealing strip 30 seals and fills the installation gap 90, which is beneficial to preventing rainwater from flowing under the photovoltaic module 60 from the installation gap 90, thereby improving the waterproof performance of the carport.

[0058] It is worth mentioning that compared with inserting the sealing strip 30 after installing the photovoltaic module 60, in this embodiment, the sealing strip 30 is pre-fixed to the mounting frame 50 through the adhesive section 31, which reduces the time of working at heights, and is beneficial to preventing the sealing strip 30 from shifting during handling and installation, thereby improving the construction efficiency.

[0059] In some embodiments, as Figure 6As shown, the outward extension arc of the upper sealing portion 32 is greater than that of the lower sealing portion 33, so that the deformability of the upper sealing portion 32 is greater than that of the lower sealing portion 33. It can be understood that under the condition that the sealing strip 30 is installed in the installation gap 90 between adjacent photovoltaic modules 60, the upper sealing portion 32 is located on the side away from the base 10, and the lower sealing portion 33 is located on the side close to the base 10. That is to say, rainwater will first contact the upper sealing portion 32. By increasing the outward extension arc of the upper sealing portion 32, the upper sealing portion 32 has a larger deformability, and then the contact length between the upper sealing portion 32 after deformation and the installation frame 50 of the photovoltaic module 60 can be increased, which is beneficial to improving the sealing effect and further improving the waterproofness of the installation device of the photovoltaic module. The deformability of the lower sealing portion 33 is small, so that the lower sealing portion 33 has good support, which can improve the structural strength of the sealing strip 30 and is beneficial to avoiding excessive deformation of the whole sealing strip 30. In at least one embodiment, under the condition that the sealing strip 30 is installed in the installation gap 90 between adjacent photovoltaic modules 60, the upper end of the sealing strip 30 does not exceed the installation frame 50 to improve the beauty and neatness of the shed.

[0060] It is worth mentioning that under the condition that the upper sealing portion 32 and the lower sealing portion 33 are pressed by the installation frame 50, the upper sealing portion 32 and the lower sealing portion 33 can provide a force towards the installation frame 50 adhered by the bonding section 31 to the bonding section 31, which is beneficial to avoiding peeling between the bonding section 31 and the installation frame 50 due to the gradual failure of the adhesive, and improving the reliability of the installation device of the photovoltaic module.

[0061] It is worth mentioning that the cross-section of the sealing strip 30 can also be other shapes that can fill the installation gap 90, such as "convex" shape, trapezoid, rectangle, and the sealing strip 30 can also be implemented as a rubber plug. The present application does not make specific restrictions on this.

[0062] In some embodiments, such as Figures 2 - 4As shown, the seal further includes a limiting section 14 which integrally extends from the main body section 12 towards the installation gap 90 between adjacent photovoltaic modules 60. The limiting section 14 supports the lower sealing portion 33 of the sealing strip 30, causing the sealing strip 30 to be deformed and clamped between adjacent photovoltaic modules 60. It can be understood that the first bearing surface 122 and the second bearing surface 123 are respectively located on both sides of the limiting section 14. In the arrangement direction of the first bearing surface 122 and the second bearing surface 123, the size of the limiting section 14 is less than or equal to the size of the sealing strip 30 in the free state. Further, under the condition that adjacent photovoltaic modules 60 are installed on the base 10, the installation frames 50 of the two photovoltaic modules 60 respectively press against both sides of the limiting section 14, so that the width of the installation gap 90 between adjacent photovoltaic modules 60 is close to or consistent with the size of the limiting section 14, making the width of the installation gap 90 less than the size of the sealing strip 30 in the free state. Thus, the sealing strip 30 can be elastically deformed and accommodated in the installation gap 90 to play a role in sealing and waterproofing. Herein, the size of the sealing strip 30 in the free state refers to the maximum distance from the upper sealing portion 32 to the bonding portion in the arrangement direction of the first bearing surface 122 and the second bearing surface 123.

[0063] That is to say, the limiting section 14 can play a role in assisting positioning to facilitate controlling the size of the installation gap 90, which is beneficial to improving the repeatability and operability of the installation of the photovoltaic module 60, thereby improving the construction efficiency. And through the auxiliary positioning of the limiting section 14, the distance between the photovoltaic modules 60 can be made more uniform, improving the aesthetics of the carport. It is worth mentioning that in the drainage direction, that is, in the inclined direction of the top surface of the carport, the limiting section 14 on the base 10 abuts against the lower side edge of the photovoltaic module 60, which is beneficial to preventing the photovoltaic module 60 from sliding down, improving the convenience and safety of construction.

[0064] In some embodiments, as Figure 10 and Figure 11 shown, the seal further includes a clamping section 15 which extends from one end of the limiting section 14 far from the main body section 12 towards one side or both sides, so that the clamping section 15 is arranged opposite to the first bearing surface 122 and / or the second bearing surface 123. The installation frame 50 of the photovoltaic module 60 can be accommodated between the clamping section 15, the limiting section 14 and the main body section 12. That is to say, a "C" - shaped structure is formed between the clamping section 15, the limiting section 14 and the first bearing surface 122 and / or between the clamping section 15, the limiting section 14 and the second bearing surface 123. The three sides of the installation frame 50 of the photovoltaic module 60 respectively abut against the clamping section 15, the limiting section 14 and the bearing surface, thereby clamping the photovoltaic module 60 on the base 10, and the installation frame 50 of the photovoltaic module 60 is hermetically connected to the base 10, which is beneficial to preventing rainwater from flowing from between the photovoltaic module 60 and the installation frame 50 to the lower part of the photovoltaic module 60.

[0065] In at least one embodiment, an adhesive is applied to the mounting frame 50 of the photovoltaic module 60 to bond the mounting frame 50 to at least one of the clamping section 15, the limiting section 14, and the main body section 12, so as to improve the connection strength between the mounting frame 50 and the base 10 and enhance the sealing and waterproof performance between the mounting frame 50 and the base 10.

[0066] It can be understood that, as Figures 8 - 11 shown, mounting frames 50 are respectively arranged on opposite sides of the photovoltaic module 60. One of the mounting frames 50 is connected to the first extension section 132 through a pressing block 20, or directly connected to the first extension section 132 through a fastener, or clamped between the clamping section 15, the limiting section 14, and the first bearing surface 122 of the main body section 12, so that one side of the photovoltaic module 60 is fixedly supported on the first bearing surface 122; further, the other mounting frame 50 is connected to the second extension section 133 through a pressing block 20, or directly connected to the second extension section 133 through a fastener, or clamped between the clamping section 15, the limiting section 14, and the second bearing surface 123 of the main body section 12, so that the other side of the photovoltaic module 60 is fixedly supported on the second bearing surface 123. The present application does not make specific limitations on this.

[0067] In some embodiments, as Figure 7 shown, the seal further includes a limiting cushion block 40. The limiting cushion block 40 is adapted to be clamped between adjacent photovoltaic modules 60 and held in the installation gap 90 between adjacent photovoltaic modules 60, so that the limiting section 14 can support the lower sealing portion 33 of the sealing strip 30, enabling the sealing strip 30 to be deformed and clamped between adjacent photovoltaic modules 60. It can be understood that, in the arrangement direction of the purlins 80, the size of the installation gap 90 between adjacent photovoltaic modules 60 can be assisted in control by the limiting section 14 on the base 10 as described above. Further, in the extension direction of the purlins 80, a limiting cushion block 40 is clamped between adjacent photovoltaic modules 60, and the size of the installation gap 90 between adjacent photovoltaic modules 60 can be assisted in control by the limiting cushion block 40, which is beneficial to improving the repeatability and operability of the installation of the photovoltaic module 60. It is worth mentioning that the limiting section 14 on the base 10 can also be replaced by a limiting cushion block 40, and the present application does not make specific limitations on this.

[0068] That is to say, through the limiting block and the limiting section 14 on the base 10, the installation gap 90 between the photovoltaic module 60 and the adjacent photovoltaic module 60 can be assisted in control, enabling the sealing strip 30 to be elastically deformed and accommodated in the installation gap 90 to play a role in sealing and waterproofing, and also making the distance between the photovoltaic modules 60 more uniform, improving the aesthetics of the carport.

[0069] In some embodiments, as Figure 1 and Figures 8 - 11The installation device of the photovoltaic module shown further includes an anti-corrosion gasket 70. The anti-corrosion gasket 70 is arranged between the placement section 112 of the base 10 and the purlin 80, so as to isolate the base 10 and the purlin 80, which is beneficial to avoid the mutual influence caused by the direct contact between the base 10 and the purlin 80, reduce the risk of rust and corrosion of the purlin 80 and the base 10, and thus extend the service life of the carport. It is worth mentioning that the anti-corrosion gasket 70 can also play a role in buffering and shock absorption, which is beneficial to avoid the hard contact between the base 10 and the purlin 80.

[0070] In some embodiments, such as Figure 1 and Figure 2 The installation steps of the installation device of the photovoltaic module shown include:

[0071] A1. Fix the installation frame 50 on one side of the photovoltaic module 60 to the second extension section 133 of the base 10 through bolts and nuts, and stick the sealing strip 30 to the back of the installation frame 50 on this side, as Figure 12 shown;

[0072] A2. Fix the base 10 to the purlin 80 through stainless steel self-tapping screws, as Figure 13 shown;

[0073] A3. Fix the installation frame 50 on one side of the next photovoltaic module 60 to the first extension section 132 of the base 10 through a pressing plate. The base 10 is installed on the installation frame 50 on the other side, and fix the base 10 on this side to the purlin 80 through stainless steel self-tapping screws, as Figure 14 shown;

[0074] A4. Repeat steps A1 to A3 to complete the paving of the top surface of the carport.

[0075] One or more embodiments of the present application also disclose a photovoltaic system, including a photovoltaic module 60 and the installation device of the above-mentioned photovoltaic module. Through the installation device of the above-mentioned photovoltaic module, the photovoltaic module 60 can be quickly and conveniently installed on the top surface of the carport, and it is beneficial to avoid rainwater flowing to the lower part of the photovoltaic module 60.
