Description

Technical Field

[0002] Building Integrated Photovoltaic (BIPV) uses photovoltaic modules as building components or building materials, making them part of the building while also having the function of generating electricity. 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 overall outdoor temperature and play a role in peak shaving for the power grid, achieving the effect of building energy conservation.

[0003] In related technologies, frameless photovoltaic modules are bonded to metal tiles through structural adhesives, or clamps are used to connect the frames of photovoltaic modules and metal tiles, and fasteners are used for fixation. For the above-mentioned related technologies, there are defects as follows: Fixing the photovoltaic modules to the metal tiles by bonding causes great difficulties in installation and disassembly, and the bonding quality of the structural adhesive is greatly affected by the on-site environment, which is not conducive to quality control.

[0038] Figure 2 It is a schematic diagram of a mounting device for a photovoltaic assembly according to some embodiments of the present application.

[0039] One or more embodiments of the present application disclose a photovoltaic assembly installation device. Figures 2 to 8 The installation device of the photovoltaic module includes a fixing assembly 10 and a mounting frame 50. The fixing assembly 10 includes a fixing body 11 and a supporting connection portion 13 connected to the fixing body 11. The supporting connection portion 13 extends from the fixing body 11 in a bent manner toward the photovoltaic module 80. Adjacent fixing bodies 11 are connected to each other and arranged oppositely. The mounting frame 50 includes a receiving portion 51 and a hook portion 52 connected to the receiving portion 51. The receiving portion 51 is suitable for receiving the photovoltaic module 80. The hook portion 52 extends from the receiving portion 51 in a bent manner toward the adjacent supporting connection portion 13, so that the hook portion 52 can be hooked to the supporting connection portion 13.

[0040] It is understandable that, referring to Figure 2 The fixing assembly 10 includes a pair of fixing bodies 11 arranged opposite to each other, and the fixing bodies 11 are connected to each other to be suitable for clamping the metal ribs 66 of the metal tile 60, so that the fixing assembly 10 can be detachably installed on the roof. Furthermore, the supporting connection portion 13 is bent and extended from the fixing body 11 to the side away from the other fixing body 11, so as to support the fixing body 11, and the supporting connection portion 13 is suitable for hooking with the hook portion 52 of the mounting frame 50. Furthermore, the mounting frame 50 is bonded to the opposite sides of the photovoltaic assembly 80, and then through the cooperation of the mounting frame 50 and the supporting connection portion 13, the photovoltaic assembly 80 can be detachably installed on the fixing assembly 10.

[0041] It is worth mentioning that the mounting frame 50 is disposed on the opposite side edges of the photovoltaic module 80, which is conducive to reducing the wind-lifting force on the edge of the photovoltaic module 80, thereby improving the wind-lifting resistance of the photovoltaic module 80. Further, the fixing assembly 10 is detachably mounted on the metal tile 60, and the mounting frame 50 is hooked with the supporting connection portion 13 of the fixing assembly 10 through the hook portion 52, so that the photovoltaic module 80 can be detachably mounted on the roof, and it is convenient to disassemble and replace the photovoltaic module 80 during later maintenance.

[0042] In some embodiments, referring to Figures 2 to 7 , the fixing assembly 10 includes a first fixing member 20 and a second fixing member 30. The first fixing member 20 includes a first main body portion 21, and the second fixing member 30 includes a second main body portion 31. The first main body portion 21 and the second main body portion 31 are detachably connected. Under the condition that the first main body portion 21 and the second main body portion 31 are connected relatively, a receiving cavity 12 is defined between the first main body portion 21 and the second main body portion 31, and the receiving cavity 12 is adapted to receive the metal rib 66 of the metal tile 60.

[0043] That is to say, the first fixing member 20 and the second fixing member 30 are disposed on both sides of the metal rib 66, and a receiving cavity 12 is formed between the first main body portion 21 and the second main body portion 3 to cooperate with the metal rib 66 for fixing. In at least one embodiment, the first fixing member 20 and the second fixing member 30 are detachably connected and fixed by a fastener 14, so that the metal rib 66 is clamped and received in the receiving cavity 12.

[0044] In some embodiments, referring to Figures 2 to 7 , the first fixing member 20 further includes a first support connecting portion 22. The first support connecting portion 22 extends upwardly by bending from a side of the first main body portion 21 facing away from the second main body portion 31, and the first support connecting portion 22 can be hooked to the hook portion 52 of the adjacent mounting frame 50; and / or the second fixing member 30 further includes a second support connecting portion 32. The second support connecting portion 32 extends upwardly by bending from a side of the second main body portion 31 facing away from the first main body portion 21, and the second support connecting portion 32 can be hooked to the hook portion 52 of the adjacent mounting frame 50.

[0045] That is to say, the first support connecting portion 22 and the second support connecting portion 32 extend from the first main body portion 21 and the second main body portion 31 in directions away from each other respectively, and the end of the first support connecting portion 22 turns back and bends towards the photovoltaic module 80 direction, so as to be hooked to the hook portion 52 of the mounting frame 50. The end of the second support connecting portion 32 also turns back and bends towards the photovoltaic module 80 direction, so as to be hooked to the hook portion 52 of the mounting frame 50. It can be understood that the first fixing member 20 and the second fixing member 30 of the fixing assembly 10 can be hooked to the two mounting frames 50 at the adjacent two side edges of the adjacent two photovoltaic modules 80.

[0046] It can be understood that in some other embodiments, one of the first fixing member 20 and the second fixing member 30 is hooked to the hook portion 52 of a mounting frame 50, and the other of the first fixing member 20 and the second fixing member 30 is connected to the other mounting frame 50 in other ways, such as: being fixed by a fastener, being inserted, being bonded, etc. The present application does not make specific limitations thereto.

[0047] In some embodiments, referring toFigures 2 to 7 The first support connection part 22 includes a first support section 221 and a first connection section 222. The first connection section 222 is bent upward in a rotary manner from the first support section 221. The second support connection part 32 includes a second support section 321 and a second connection section 322. The second connection section 322 is bent upward in a rotary manner from the first support section 221. Among them, the bending openings defined by the first connection section 222 and the second connection section 322 are arranged oppositely. Under the condition that the first connection section 222 is hooked to the adjacent mounting frame 50, the first connection section 222 is stacked under the adjacent hook part 52 in a hooked manner. Under the condition that the second connection section 322 is hooked to the adjacent mounting frame 50, the second connection section 322 is stacked under the adjacent hook part 52 in a hooked manner.

[0048] Specifically, the first support section 221 of the first fixing member 20 is adapted to be attached to the metal tile 60, so as to support the first main body part 21 to stand on the connection support 71. One end of the first support section 221 away from the first main body part 21 is bent in a rotary manner toward the side away from the connection support 71 to form the first connection section 222. Further, the opening formed between the first connection section 222 and the first support section 221 faces the first main body part 21. Furthermore, the receiving part 51 of the mounting frame 50 is fixed to the photovoltaic module 80. The hook part 52 is bent from one end of the receiving part 51 facing the fixing main body 11 in a rotary manner toward the side away from the photovoltaic module 80. Thus, under the condition that the mounting frame 50 is hooked to the first fixing member 20, the hook part 52 can extend into the space between the first connection section 222 and the first support section 221, so that the receiving part 51, the first connection section 222, the hook part 52, and the first support section 221 are stacked.

[0049] Similarly, the second support section 321 of the second fixing member 30 is adapted to be attached to the metal tile 60, so as to support the second main body part 31 to stand on the connection support 71. One end of the second support section 321 away from the second main body part 31 is bent in a rotary manner toward the side away from the connection support 71 to form the second connection section 322. Further, the opening formed between the second connection section 322 and the second support section 321 faces the second main body part 31. Furthermore, under the condition that the mounting frame 50 is hooked to the second fixing member 30, the hook part 52 can extend into the space between the second connection section 322 and the second support section 321, so that the receiving part 51, the second connection section 322, the hook part 52, and the second support section 321 are stacked.

[0050] It is worth mentioning that by laminating the hook portion 52 with the first connecting section 222 and laminating the other hook portion 52 with the second connecting section 322, it is beneficial to increase the stress area between the first fixing member 20, the second fixing member 30 and the mounting frame 50. Furthermore, it is beneficial to improve the wind uplift resistance of the first fixing member 20, the second fixing member 30 and the mounting frame 50, and reduce the risk of disconnection between the first fixing member 20, the second fixing member 30 and the mounting frame 50.

[0051] In some embodiments, referring to Figures 2 to 7 , the second main body portion 31 includes an extension section 311, a main body section 312 and an enlarged section 314. The extension section 311 extends radially from the upper side of the main body section 312 towards the first main body portion 21, defining the accommodation cavity 12 in the space formed by the first main body portion 21, the extension section 311 and the main body section 312 of the second main body portion 31. Under the condition that the first main body portion 21 and the second main body portion 31 are relatively connected, the extension section 311 can abut against the first main body portion 21. The enlarged section 314 extends convexly from the lower side of the main body section 312 towards the accommodation cavity 12, so as to define the metal rib 66 of the metal tile 60.

[0052] It can be understood that the extension section 311 is located at one end of the second main body portion 31 away from the photovoltaic module 80, and the extension section 311 is adapted to abut against one end of the first main body portion 21 away from the photovoltaic module 80; the fastener 14 is close to the middle section area of the first main body portion 21 and the second main body icon 31, so as to detachably connect the first fixing member 20 and the second fixing member 30; the enlarged section 314 is located at one end of the second main body portion 31 close to the photovoltaic module 80, so as to cooperate with the first main body portion 21 to clamp the metal rib 66. Furthermore, through the extension section 311, the fastener 14 and the enlarged section 314, it is beneficial to make the upper, middle and lower parts of the first main body portion 21 and the second main body portion 31 be evenly stressed and connected in parallel. Under the condition of tightening the fastener 14, the deformation of the first main body portion 21 and the second main body portion 31 can be reduced.

[0053] In at least one embodiment, referring to Figure 2 , Figure 3 , Figure 6 and Figure 7The first main body 21 has a positioning groove 211, which is arranged opposite to the extension section 311 of the second main body 31 and is adapted to the extension section 311. Specifically, under the condition that the first main body 21 and the second main body 31 are relatively connected, the extension section 311 is inserted into the positioning groove 211, so as to reduce the relative sliding of the first fixing member 20 and the second fixing member 30, and facilitate the installation of the fastener 14. It is worth mentioning that the positioning groove 211 is arranged at the end of the first main body 21 away from the photovoltaic component 80, and the extension section 311 is arranged at the end of the second main body 31 away from the photovoltaic component 80, so as to obtain a better positioning effect, and also facilitate the alignment of the construction personnel during installation.

[0054] In at least one embodiment, reference Figure 6 and Figure 7 The enlarged section 314 is implemented as a limiting section 316, which is located at one end of the second main body 31 close to the photovoltaic assembly 80 and extends obliquely toward a side away from the second supporting connection portion 32. When the first main body 21 and the second main body 31 are relatively connected, the metal rib 66 is suitable for being clamped between the limiting section 316 and the first main body 21.

[0055] In other embodiments, referring to Figures 2 to 5 The enlarged section 314 and the second supporting section 321 extend from both sides of the main section 312 in opposite directions respectively. The second main body 31 is further provided with a reinforcing section 315 which obliquely connects the enlarged head of the enlarged section 314 and the main section 312 .

[0056] It is understandable that the expansion section 314 and the second support section 321 are both in contact with the metal tile 60, so as to further improve the stability of the second fixing member 30 placed on the metal tile 60. In addition, the reinforcement section 315 is able to connect the end of the expansion section 314 and the main section 312 in an inclined manner to form a triangular structure, so as to further improve the structural strength of the second main body 31, thereby facilitating the improvement of the load-bearing capacity of the second main body 31. When the first fixing member 20 and the second fixing member 30 are connected by the fastener 14, it is helpful to avoid the risk of deformation of the expansion section 314 and the main section 312 due to over-tightening of the fastener 14.

[0057] In at least one embodiment, a cavity 317 is formed between the reinforcing section 315, the main section 312 and the enlarged section 314, which is beneficial to reducing the volume and weight of the second main portion 31, thereby helping to reduce the load of the photovoltaic module installation device on the roof.

[0058] In some embodiments, reference Figures 2 to 5, the main body section 312 is provided with at least a partial bent section 313, and the bent section 313 is inclined outwardly and arranged on the lower side of the main body section 312, so as to expand the lower side space of the accommodation cavity 12, which is beneficial to avoiding interference between the metal rib 66 and the main body section 312.

[0059] In at least one embodiment, referring to Figure 2 and Figure 3 , the bent section 313 extends obliquely to connect the main body section 312 and the second support connection part 32, and the strengthening section 315 extends bendedly to connect the middle section area of the main body section 312 and the end of the enlarged section 314. Furthermore, on the basis of expanding the lower side space of the accommodation cavity 12, the second main body part 31 has better structural strength.

[0060] In at least one embodiment, referring to Figure 4 and Figure 5 , the bent section 313 extends bendedly to connect the main body section 312 and the second support connection part 32, and the strengthening section 315 extends obliquely to connect the middle section area of the main body section 312 and the end of the enlarged section 314. Furthermore, on the basis of expanding the lower side space of the accommodation cavity 12, the second main body part 31 has better structural strength.

[0061] In some embodiments, referring to Figure 8 , the mounting frame 50 is further provided with an adhesive member 91, the adhesive member 91 is coated on the upper surface of the receiving part 51, and the mounting frame 50 can bond the receiving part 51 and the back surface of the photovoltaic module 80 through the adhesive member 91; the hook part 52 is bent downward from the receiving part 51, and the bent opening of the hook part 52 is suitable for hooking with the adjacent support connection part 13.

[0062] It can be understood that the adhesive member 91 is arranged between the receiving part 51 and the photovoltaic module 80, so that the mounting frame 50 is adhesively fixed to the photovoltaic module 80 and can play a buffering effect, which is beneficial to avoiding hard contact between the mounting frame 50 and the photovoltaic module 80, and further reducing the risk of the photovoltaic module 80 being cracked.

[0063] In the related art, the frameless photovoltaic module is adhesively bonded to the metal tile through structural glue. This fixing method causes great difficulties in installation and disassembly, and the bonding quality of the structural glue is greatly affected by the on-site environment, which is not conducive to quality control; in addition, due to a lot of construction dust on site, the metal tile needs to be cleaned before applying glue, which is likely to affect the on-site construction efficiency; during installation, it is difficult to control the bonding position of the photovoltaic module, and it is difficult to disassemble after bonding, with a low error tolerance.

[0064] In this embodiment, the installation frame 50 and the photovoltaic module 80 can be pre-bonded and installed before leaving the factory, so as to facilitate injecting glue in a constant temperature and humidity environment to form the bonding member 91, which is beneficial to improving the bonding quality and the connection reliability between the photovoltaic module 80 and the installation frame 50. And the installation frame 50 and the fixing component 10 are detachably connected by hooking the hook portion 52 and the support connection portion 13, and the installation and disassembly operations are simple, which is beneficial to reducing the difficulty of disassembling the photovoltaic module during on-site installation and later maintenance and repair.

[0065] It is worth mentioning that the direct bonding of the photovoltaic module 80 to the installation frame 50 is beneficial to avoiding the setting of a photovoltaic frame on the periphery of the photovoltaic module 80, thereby reducing the decrease in power generation caused by dust accumulation.

[0066] One or more embodiments of the present application also disclose a photovoltaic roofing system. Refer to Figures 1 to 3 , the photovoltaic roofing system includes the above-mentioned installation device for the photovoltaic module, the metal tile 60 and the photovoltaic module 80. The adjacent metal tiles 60 cooperate to form a metal rib 66. The metal rib 66 is fixedly connected between the relatively arranged fixing main bodies 11 through the cooperation of the installation device for the photovoltaic module, so that the fixing component 10 is installed on the metal tile 60. Further, the photovoltaic module 80 is fixedly connected to the fixing component 10 through the installation frame 50.

[0067] In some embodiments, the photovoltaic roofing system further includes a connecting support 71, a wind-resistant support 72 and a gasket 92. The metal tile 60 includes a main body portion 61, an embedding portion 62, a supporting portion 63, a bearing portion 64 and a locking edge portion 65. The embedding portion 62 projects from the main body portion 61 towards the photovoltaic module 80 at intervals, and is suitable for supporting the middle part of the photovoltaic module 80. The supporting portions 63 respectively protrude from the ends of the main body portion 61 towards the locking edge portion 65 in a boss shape to form a bearing portion 64 for placing the fixing component 10. The connecting support 71 is fixedly connected to the locking edge portion 65 of the adjacent metal tile 60 to form a metal rib 66. The wind-resistant support 72 is embedded in the embedding portion 62, and the gasket 92 is suitable for being installed between the embedding portion 62 and the photovoltaic module 80.

[0068] It can be understood that, referring to Figures 9 to 11 , the middle part of the photovoltaic module 80, that is, the middle area of the photovoltaic module 80, can be supported by the supporting portion 63 of the metal tile 60, which is beneficial to improving the bearing capacity of the photovoltaic roofing system. Further, when installing and repairing the photovoltaic roofing system, it is convenient for engineering personnel to step on the photovoltaic module 80.

[0069] In at least one embodiment, refer to Figure 9 and Figure 10, the metal tile 60 further has a rib 611 or a boss 612, and the rib 611 or the boss 612 protrudes from the middle area of the body portion 61 in a direction away from the roof surface, so as to improve the structural strength of the body portion 61.

[0070] It can be understood that a gasket 92 is clamped between the supporting portion 63 of the metal tile 60 and the photovoltaic module 80, which is beneficial to avoiding hard contact between the supporting portion 63 and the photovoltaic module 80, and thus reducing the risk of hidden cracks in the photovoltaic module 80. Further, the supporting portion 63 is adapted to be fitted with a wind-resistant support 72 fixed on the roof surface, which is beneficial to improving the wind resistance performance of the metal tile 60, and the wind-resistant support 72 abuts against the supporting portion 63, so as to support the middle area of the photovoltaic module 80, which is beneficial to reducing the suspended span of the photovoltaic module 80, and thus improving the load-bearing capacity of the photovoltaic module 80.
