[0045] Figure 2 It is a schematic diagram of a mounting device for a photovoltaic assembly according to some embodiments of the present application.

[0046] One or more embodiments of the present application disclose a photovoltaic assembly installation device. Figures 1 to 6The installation device of the photovoltaic module includes a fixing component 1, the fixing component 1 includes a fixing seat 10 and a supporting member 30, the fixing seat 10 is provided with a locking groove 122, the supporting member 30 includes a supporting connection portion 31 and a bearing portion 32, the bearing portion 32 is bent from the supporting connection portion 31 and extends toward the photovoltaic module 90, and the supporting connection portion 31 is detachably embedded in the locking groove 122 above the fixing seat 10; the installation component 2, the installation component 2 includes a mounting frame 50 and a mounting member 40, the mounting frame 50 is detachably connected to the bearing portion 32 of the fixing component 1 through the mounting member 40, and the mounting frame 50 is suitable for installing the photovoltaic module 90.

[0047] That is to say, referring to Figure 2 , the support member 30 is detachably embedded in the locking groove 122 above the fixing seat 10 through the support connection portion 31, so that the support member 30 and the fixing seat 10 are embedded and fixed by the first fastener 13. It can be understood that when the photovoltaic component 90 is subjected to wind lifting force, the force will be transmitted to the support member 30 through the installation component 2 installed on the bearing portion 32 of the support member 30, so that the support member 30 has a tendency to flip relative to the fixing seat 10. When the support member 30 and the fixing seat 10 are embedded and connected, it is beneficial to increase the force-bearing area between the support member 30 and the fixing seat 10, which is beneficial to improve the wind-resistant ability of the support member 30 and reduce the risk of the support member 30 and the fixing seat 10 being disengaged. In addition, the first fastener 13 is beneficial to prevent the support member 30 from sliding relative to the fixing seat 10, so as to further reduce the risk of the support member 30 and the fixing seat 10 being disengaged.

[0048] In some embodiments, reference Figure 4 The supporting connection portion 31 includes a supporting section 311, a connecting section 312 and a supporting joint 314. Both sides of the supporting section 311 are connected to the connecting section 312. One side of each connecting section 312 away from the supporting section 311 is integrally connected downwardly to the bearing portion 32. The bearing portions 32 on both sides of the supporting section 311 extend outward in different directions. The supporting connection portion 31 is further provided with a covering cavity 313. The covering cavity 313 is suitable for the supporting member 30 to cover the fixing seat 10. The supporting joint 314 expands and protrudes from the supporting section 311 to the covering cavity 313, so that the supporting joint 314 is embedded in the locking groove 122 opened along the height direction of the fixing seat 10.

[0049] Specifically, refer to Figure 3 and Figure 4, the locking portion 12 of the fixing seat 10 includes a receiving platform 121, and the locking groove 122 is opened on the receiving platform 121 along the height direction. Further, the supporting connection portion 31 of the supporting member 30 has a supporting section 311, and the supporting section 311 is suitable for being fitted with the receiving platform 121, so that the supporting member 30 is stably placed on the fixing seat 10. Furthermore, a pair of connecting sections 312 integrally extend downward from both sides of the supporting section 311, and a covering cavity 313 is formed between the connecting sections 312 and the support, and the covering cavity 313 is suitable for accommodating the fixing body part 11, so that the supporting member 30 is covered on the outside of the fixing body part 11, thereby facilitating improving the connection reliability between the supporting member 30 and the fixing seat 10. Furthermore, the supporting joint 314 protrudes from the supporting section 311 toward the covering cavity 313, and the supporting joint 314 is able to be mutually engaged with the locking groove 122.

[0050] It is worth mentioning that in the related art, two support members 30 of different shapes are combined to be fixed to the boat-shaped support 81 to support the photovoltaic module 90. In this embodiment, the support member 30 is formed by integrated mold casting, which reduces the number of molds, thereby helping to reduce production costs and improve production efficiency.

[0051] In at least one embodiment, reference Figure 4 The extension lengths of the bearing parts 32 on both sides of the fixing component 1 are consistent, and the fixing component 1 is provided with a serration structure 70, which is respectively formed on the upper surface of the bearing part 32 and the contact surface of the mounting frame 50 arranged relative to the bearing part 32.

[0052] It is understandable that the extension lengths of the bearing parts 32 on both sides of the support 30 are consistent, which is conducive to reducing the influence of the eccentricity of the support 30 on the stability of the fixing assembly 1, thereby improving the bearing capacity of the fixing assembly 1, and making the wind resistance performance of the photovoltaic roof system better. In addition, a sawtooth structure 70 is provided on the relative contact surfaces of the bearing part 32 and the mounting frame 50, so as to reduce the risk of sliding displacement of the mounting frame 50 relative to the bearing part 32, thereby helping to improve the anti-falling property of the mounting frame 50, and improving the connection reliability of the photovoltaic assembly 90 installed on the mounting device of the photovoltaic assembly.

[0053] In other embodiments, reference Fig.14 and Fig.15 The supporting connection portion 31 includes a connecting section 312 and a supporting joint 314. The connecting section 312 is connected to the bearing portion 32 and extends upward. The locking groove 122 is opened on the side of the fixing seat 10. The supporting joint 314 expands and protrudes from the connecting section 312 to the locking groove 122, so that the supporting joint 314 is embedded in the locking groove 122 opened in the fixing seat 10 along the direction of the photovoltaic component 90.

[0054] Specifically, the locking groove 122 is provided on the side of the locking portion 12 facing the photovoltaic component 90. Furthermore, the supporting connection portion 31 of the supporting member 30 has a connecting section 312. A supporting joint 314 is protrudingly provided on the side of the connecting section 312 facing away from the bearing portion 32. The supporting joint 314 is suitable for mutual engagement with the locking groove 122, thereby fixing the supporting member 30 to the fixing seat 10.

[0055] It is understandable that, under the condition that two support members 30 are installed on both sides of the fixing seat 10, the photovoltaic module installation device can be fixedly connected to two adjacent photovoltaic modules 90. Under the condition that one support member 30 is installed on one side of the fixing seat 10, the photovoltaic module installation device is suitable for being arranged at the edge of the roof photovoltaic system, and only one photovoltaic module 90 is fixedly connected. It is worth mentioning that the support member 30 can be formed by integrated open mold casting, which reduces the number of molds, thereby helping to reduce production costs and improve production efficiency.

[0056] In some embodiments, the mounting frame 50 includes a frame main body 51 and a frame connecting portion 52 integrally connected to the frame main body 51, the frame main body 51 is suitable for installing the photovoltaic component 90, the frame connecting portion 52 extends from the frame main body 51 to the load-bearing portion 32, and the frame connecting portion 52 and the load-bearing portion 32 are detachably connected by the mounting member 40.

[0057] That is to say, referring to Figure 2 , through the frame connection part 52 and the mounting member 40, the mounting frame 50 is detachably connected to the bearing part 32 of the support member 30, and the frame main body 51 of the mounting frame 50 is suitable for connecting with the photovoltaic module 90, so that the photovoltaic module 90 can be detachably installed on the fixed component 1. It can be understood that before leaving the factory, the mounting frame 50 is suitable for pre-bonding and installing with the photovoltaic module 90. At the construction site, the installation of the photovoltaic module 90 can be completed by fixing the mounting frame 50 with the bearing part 32 of the support member 30, which is conducive to reducing the difficulty of installation and improving the efficiency of on-site construction.

[0058] In some embodiments, the fixing assembly 1 further includes a clamping member 20, and the fixing seat 10 is provided with a accommodating cavity 113, the accommodating cavity 113 is located below the locking groove 122, and the clamping member 20 can be adjustably locked in the accommodating cavity 113, so that the metal rib 83 is suitable for nesting between the clamping member 20 and the fixing seat 10.

[0059] Specifically, when the fixing seat 10 is installed on the boat-shaped support 81, the accommodating cavity 113 of the fixing seat 10 is suitable for accommodating the metal rib 83 and the clamping member 20 of the metal tile 82, and the metal rib 83 is located between the fixing seat 10 and the clamping member 20, and the second fastener 14 is suitable for being threadedly connected to the fixing seat 10, and one end of the second fastener 14 is against the clamping member 20. By adjusting the second fastener 14, the second fastener 14 can push the clamping member 20 to move toward the metal rib 83, thereby clamping the metal rib 83 between the fixing seat 10 and the clamping member 20, so that the fixing assembly 1 is installed on the boat-shaped support 81 and connected to the metal rib 83.

[0060] It is worth mentioning that by accommodating the metal rib 83 in the accommodating cavity 113 of the fixing seat 10 and clamping the metal rib 83 by the fixing seat 10 and the clamping member 20, it is helpful to improve the connection strength of two adjacent metal tiles 82, thereby helping to improve the wind-resistant ability of the photovoltaic roof system.

[0061] In at least one embodiment, the clamping member 20 is provided with a contact portion 21, a limiting portion 22 and a limiting groove 23, wherein the limiting portion 22 extends from both sides of the contact portion 21 in a direction away from the metal rib 83, and the limiting groove 23 is formed between the contact portion 21 and the limiting portion 22, and the notch of the limiting groove 23 gradually decreases from the outside to the inside.

[0062] It is understandable that, referring to Figure 1 Compared with the second fastener 14 directly abutting against the vertical part of the metal rib 83, in this embodiment, a clamping member 20 is arranged between the second fastener 14 and the metal rib 83. The contact portion 21 of the clamping member 20 abuts against the vertical part of the metal rib 83, thereby increasing the contact area and reducing the wear of the metal rib 83 when the second fastener 14 rotates, thereby improving the reliability of the connection between the fixing assembly 1 and the metal rib 83. The limiting portion 22 extends from both sides of the contact portion 21 in a direction away from the vertical part of the metal rib 83 to form a limiting groove 23 between the contact portion 21 and the limiting portion 22. The limiting groove 23 can accommodate the second fastener 14, which is conducive to aligning the second fastener 14 with the clamping member 20 during installation, facilitating operation, and the limiting portion 22 can protect the second fastener 14. Further, the transverse part of the metal rib 83 is clamped between the limiting portion 22 and the fixed main body 11, thereby improving the connection reliability between the installation device of the photovoltaic assembly and the metal rib 83. It is worth mentioning that the notch of the limiting groove 23 gradually increases from the inside to the outside, so as to play a guiding role, making it easier for the second fastener 14 to enter the limiting groove 23.

[0063] In some embodiments, reference Figure 3The fixed main body 11 further includes a locking portion 12, a leg section 111, a placement section 112 and a protrusion 110. The leg section 111 extends downward from both sides of the locking portion 12 as a whole. A accommodating cavity 113 is formed between the leg section 111 and the locking portion 12. The placement section 112 extends from the end of one side of the leg section 111 along the metal tile 82. The protrusion 110 protrudes from the side of the other side of the leg section 111 toward the clamping member 20. The protrusion 110 of the clamping member 20 and the fixing seat 10 are fixedly connected by the second fastener 14.

[0064] It can be understood that the leg section 111 is used to support the locking portion 12 so that the locking portion 12 is located above the metal rib 83, and a receiving cavity 113 is formed between the leg section 111 and the locking portion 12 to accommodate the metal rib 83. The placement section 112 extends from one of the leg sections 111 along the direction of the metal tile 82, and the placement section 112 fits the metal tile 82, so as to increase the contact area between the fixing seat 10 and the metal tile 82, so that the fixing seat 10 is more stably arranged above the boat-shaped support 81. A protrusion 110 is provided on the side of the other leg section 111, and the protruding direction of the protrusion 110 is consistent with the extension direction of the second fastener 14, so that the thickness of the leg section 111 in the extension direction of the second fastener 14 is increased by the protrusion 110, which is conducive to extending the screwing length of the second fastener 14 and the fixing seat 10, and thus is conducive to improving the connection strength between the fixing member and the fastener.

[0065] In some embodiments, Figure 4 As shown, the bearing portion 32 includes an extension section 321 and a stop section 322. The stop section 322 extends upward from the end of the extension section 321 and is used to stop the mounting frame 50, which helps to prevent the mounting frame 50 from sliding off the extension section 321. The mounting member 40 is at least a pair of hook members 41, and the mounting frame 50 is provided with a frame connecting groove 521. The upper end of the hook member 41 is embedded in the frame connecting groove 521. The mounting assembly 2 further includes a limit block 61 and a third fastener 62. The third fastener 62 is detachably connected to the limit block 61 and the hook member 41, so that the bearing portion 32 is clamped and fixed between adjacent hook members 41 along the installation direction of the photovoltaic assembly 90.

[0066] Specifically, a pair of hook members 41 are arranged on opposite sides of the bearing portion 32 along the extension direction of the purlin, the upper end of the hook member 41 is interlocked with the mounting frame 50, the limit block 61 is arranged between the lower end of the hook member 41 and the bearing portion 32, and the limit block 61 and the hook member 41 are detachably connected by the third fastener 62, so that the extension section 321 of the bearing portion 32 is clamped between the mounting frame 50 and the limit block 61. In other words, the limit block 61 and the extension section 321 of the bearing portion 32 are clamped by the mounting frame 50 and the hook member 41 connected to the mounting frame 50, and the limit block 61 and the hook member 41 are fixed by the third fastener 62, so that the limit block 61 is located below the extension section 321, and the extension section 321 is clamped by the mounting frame 50 and the limit block 61, so that the mounting frame 50 is connected to the bearing portion 32.

[0067] It can be understood that when the photovoltaic module 90 is subjected to wind-lifting force, the force will be transmitted to the hook member 41 and the bearing part 32 through the mounting frame 50, causing the hook member 41 to have a tendency to flip relative to the bearing part 32. Furthermore, when the limit block 61 fixes a pair of hook members 41, the force-bearing area between the hook member 41 and the bearing part 32 is increased by the limit block 61, thereby improving the wind-lifting resistance between the hook member 41 and the bearing part 32 and reducing the risk of detachment between the mounting frame 50 and the bearing part 32.

[0068] In some embodiments, reference Figure 5 The hook member 41 is provided with a hanging section 411, a resting section 412, a limiting section 413, a placement cavity 414 and a hook joint 42. The placement cavity 414 is formed between the hanging section 411 and the limiting section 413. The resting section 412 laterally connects the limiting section 413 and the hanging section 411. The hook joint 42 expands and extends from the top of the hanging section 411 toward the frame connecting groove 521, so that the hook joint 42 is embedded in the frame connecting groove 521. The limiting block 61 is placed in the placement cavity 141, and the limiting block 61 and the resting section 412 are fixedly connected by a third fastener 62, so that the bearing portion 32 is clamped between adjacent limiting blocks 61.

[0069] That is, the upper end of the hook member 41 has a hook joint 42, and the hook member 41 is detachably engaged with the frame connection groove 521 of the mounting frame 50 through the hook joint 42, so that the hook member 41 and the mounting frame 50 are engaged. Further, the hanging section 411 is connected to the hook joint 42 and the resting section 412, so that the resting section 412 is located below the extension section 321 of the support member 30, so that the limit block 61 is suitable for being placed on the resting section 412, so that the limit block 61 is clamped between the extension section 321 and the resting section 412. Furthermore, a limit section 413 is provided at the end of the resting section 412, and a placement cavity 414 is formed between the limit section 413, the resting section 412 and the hanging section 411, so as to prevent the limit block 61 from being separated from the hook member 41, and to improve the connection reliability between the limit block 61 and the hook member 41. It can be understood that when the photovoltaic component 90 is subjected to wind-lifting force, the force will be transmitted to the hook member 41 through the mounting frame 50, causing the mounting frame 50 to have a tendency to flip relative to the hook member 41. Furthermore, when the hook joint 42 and the mounting frame 50 are engaged, it is beneficial to increase the force-bearing area between the hook member 41 and the mounting frame 50; thereby, it is beneficial to improve the wind-lifting resistance of the hook member 41 and the mounting frame 50, and reduce the risk of detachment between the hook member 41 and the mounting frame 50.

[0070] In some embodiments, reference Figure 2 and Figure 6 The mounting assembly 2 is further provided with an adhesive 63, the frame main body 51 is provided with a positioning section 512, the positioning section 512 protrudes upward from one end of the frame connecting portion 52, and the adhesive 63 is arranged in the area formed by the upper surface of the frame main body 51 and the positioning section 512, and the frame main body 51 and the back side of the photovoltaic assembly 90 are bonded by the adhesive 63.

[0071] Specifically, the photovoltaic assembly 90 is placed on the upper surface of the frame body 51 and fixed to the mounting frame 50 by the adhesive 63, which is beneficial to improve the connection strength between the photovoltaic assembly 90 and the mounting frame 50. Furthermore, the positioning section 512 is able to abut against the side of the photovoltaic assembly 90 to facilitate the installation and positioning of the photovoltaic assembly 90. At the same time, the side of the photovoltaic assembly 90 is protected by the positioning section 512, which is beneficial to reduce the risk of damage to the edge of the photovoltaic assembly 90.

[0072] Specifically, in the related art, the frameless photovoltaic module 90 is bonded to the metal tile 82 by structural adhesive. This fixing method makes installation and disassembly more difficult, and the bonding quality of the structural adhesive is greatly affected by the on-site environment, which is not conducive to quality control; and because there is a lot of dust in the on-site construction, the metal tile 82 needs to be cleaned before gluing, which is easy to affect the on-site construction efficiency; during installation, the bonding position of the photovoltaic module 90 is difficult to control, and it is difficult to disassemble after bonding, and the fault tolerance rate is low. In this embodiment, the mounting frame 50 and the photovoltaic module 90 can be pre-bonded and installed before leaving the factory, so as to control the injection of glue under a constant temperature and humidity environment, which is conducive to improving the bonding quality and improving the connection reliability of the photovoltaic module 90 and the mounting frame 50. And the mounting frame 50 and the bearing portion 32 of the support member 30 are detachably connected by the mounting member 40, and the installation and disassembly operations are simple, which is conducive to reducing the difficulty of disassembling the photovoltaic module 90 during on-site installation and later maintenance and repair.

[0073] In some embodiments, reference Figure 7 and Figure 8 The frame main body 51 is provided with a frame segment 513 and an installation cavity 514. The frame segment 513 is arranged above the frame connecting portion 52. The lateral opening of the installation cavity 514 faces the photovoltaic component 90. The installation cavity 514 is formed in the frame segment 513 and is suitable for the side of the photovoltaic component 90 to be clamped by the frame segment 513.

[0074] It is understandable that the side of the photovoltaic component 90 is accommodated in the installation cavity 514, which is beneficial to improving the connection reliability between the photovoltaic component 90 and the installation frame 50, and is also beneficial to reducing the need for modification of existing production lines.

[0075] In other embodiments, reference Figures 9 to 13 The frame main body 51 is provided with a frame segment 513 and an installation cavity 514. The frame connecting portion 52 is integrally connected to the frame segment 513 along the extension direction. The installation component 2 further includes a third fastener 62. The third fastener 62 is fixedly connected to the frame connecting portion 52 and the extension segment 321 of the bearing portion 32. The lateral opening of the installation cavity 514 faces the photovoltaic component 90. The installation cavity 514 is formed in the frame segment 513, which is suitable for the side of the photovoltaic component 90 to be clamped by the frame segment 513. The bearing portion 32 includes an extension segment 321, a support portion 323 and a rubber strip 64. The support portion 323 is located at the outer end of the extension segment 321. The rubber strip 64 is laid in the support portion 323 to be supported below the photovoltaic component 90.

[0076] That is to say, the side of the photovoltaic assembly 90 is accommodated in the installation cavity 514, which is conducive to improving the connection reliability between the photovoltaic assembly 90 and the installation frame. In addition, the support portion 323 located at the end of the extension section 321 is extended to the lower side of the photovoltaic assembly 90, thereby forming a support for the photovoltaic assembly 90, which is conducive to further improving the load capacity of the installation device of the photovoltaic assembly. Furthermore, the rubber strip 64 is provided on the support portion 323, which is conducive to avoiding hard contact between the photovoltaic assembly 90 and the support member 30, and reducing the risk of hidden cracks in the photovoltaic assembly 90. At the same time, it is conducive to reducing the need for modification of existing production lines.

[0077] One or more embodiments of the present application also disclose a photovoltaic roof system. Figure 1 The photovoltaic roof system includes any of the above-mentioned photovoltaic component mounting devices, metal tiles 82, metal ribs 83 formed by the cooperation of adjacent metal tiles 82, and photovoltaic components 90. The metal ribs 83 are nested in the photovoltaic component mounting device, so that the photovoltaic component mounting device is fixed on the metal tiles 82, and the photovoltaic component mounting device is installed along the side of the photovoltaic component 90.

[0078] Specifically, after installing the metal tiles 82 to obtain a qualified metal roof, the steps of installing the photovoltaic roof system further include:

[0079] S1, installing the fixing base 10 and the clamping member 20 on the boat-shaped support 81 through the second fastener 14;

[0080] S2, installing the support member 30 on the fixing seat 10 through the cooperation between the support joint 314 and the locking groove 122, and fixing it with the first fastener 13;

[0083] S5, placing the limiting block 61 in the placement groove of the hook member 41 and fixing it by the third fastener 62, so that the bearing portion 32 is clamped between the limiting block 61 and the mounting frame 50.

[0084] It is worth mentioning that the mounting frame 50 and the photovoltaic module 90 are pre-bonded and installed before leaving the factory to facilitate the injection of glue under a constant temperature and humidity environment, which is beneficial to improve the bonding quality and the connection reliability between the photovoltaic module 90 and the mounting frame 50.
