[0002] In related technologies, photovoltaic systems can use photovoltaic brackets to fix photovoltaic modules on the mounting surface of building roofs, building facades, etc., so that the photovoltaic modules can be stably oriented towards the light source and ensure the stable operation of the photovoltaic system.

[0003] However, the existing photovoltaic mounting system involves many steps when installing photovoltaic modules, usually requiring a large number of skilled construction workers to complete the installation work, resulting in low assembly efficiency and reduced practicality of the photovoltaic system. Utility Model Content

[0004] Several embodiments in this application propose a photovoltaic bracket and a photovoltaic system, aiming to improve the practicality and assembly efficiency of the photovoltaic bracket.

[0005] One embodiment of this application proposes a photovoltaic support bracket including a bracket body and a limiting structure. The bracket body includes at least two supporting beams, which are spaced apart on the mounting surface. The sides of the supporting beams are provided with fixing grooves, and the fixing grooves of two adjacent supporting beams are arranged opposite each other to accommodate the opposite two sides of the photovoltaic module. The limiting structure is connected to the supporting beams to limit and fix the photovoltaic module.

[0006] In one embodiment, the limiting structure includes a first limiting member connected to the supporting beam, one end of which can extend into the fixing groove to abut against the side of the photovoltaic module.

[0007] In one embodiment, the supporting beam is provided with a receiving groove, the receiving groove and the fixing groove are spaced apart, and the supporting beam is provided with a communicating hole connecting the receiving groove and the fixing groove; the first limiting member includes a locking block and a fastening bolt, the locking block is fixedly disposed in the receiving groove, the fastening bolt is connected to the locking block, and one end of the fastening bolt extends through the communicating hole into the fixing groove and abuts against the side of the photovoltaic module.

[0008] In one embodiment, the inner wall of the receiving groove is provided with a slot, and one side of the locking block is provided with a locking protrusion, which engages with the slot.

[0009] In one embodiment, the end of the supporting beam is provided with a first opening communicating with the receiving groove and the slot; the main body of the bracket also includes a stop block, one side of which is provided with a fixing rib, the fixing rib being inserted into the slot, and the stop block can open or close the first opening.

[0010] In one embodiment, the photovoltaic support further includes a spacer disposed in the fixing groove and connected to the side of the photovoltaic module, with the first limiting member abutting against the spacer.

[0011] In one embodiment, the limiting structure includes a second limiting member disposed within the fixing groove, the second limiting member being used to limit and separate two adjacent photovoltaic modules.

[0012] In one embodiment, the support body further includes a base, which is connected to the support beam and fixedly connected to the mounting surface.

[0013] In one embodiment, the supporting beam has two flanges spaced apart on one side, and the base has two fastening grooves arranged opposite to each other, with the two flanges respectively engaging in the two fastening grooves.

[0014] In one embodiment, the end of the support beam is provided with a second opening communicating with the fixing groove, and the bracket body further includes a stop block connected to the support beam, which can open or close the second opening.

[0015] An embodiment of this application also proposes a photovoltaic system, which includes photovoltaic modules and a photovoltaic support, wherein the photovoltaic support is the aforementioned photovoltaic support, and the photovoltaic modules are mounted on the photovoltaic support.

[0016] In the various embodiments provided in this application, at least two support beams are spaced apart on the mounting surface. The spacing between adjacent support beams corresponds to the size of the photovoltaic module. Using fixing slots on the sides of the support beams, the opposite sides of the photovoltaic module can be respectively inserted into the fixing slots of the two adjacent support beams. A limiting structure provides a certain degree of restraint and fixation for the photovoltaic module, ensuring its stable installation on the bracket body. By creating fixing slots on the sides of the overall support beams, construction workers can arrange the support beams at certain intervals on the mounting surface and directly insert the photovoltaic module into the fixing slots of two adjacent support beams. This allows the two adjacent support beams to clamp the photovoltaic module, achieving pre-installation. Then, the limiting structure is operated on the support beams to restrain and fix the photovoltaic module to the two adjacent support beams, thus achieving a stable installation of the photovoltaic module on the photovoltaic bracket. This eliminates the need for multiple construction workers to perform assembly work, effectively simplifying the installation process of photovoltaic brackets and photovoltaic modules, enabling more convenient assembly of photovoltaic modules on photovoltaic brackets, and improving the assembly efficiency and practicality of the photovoltaic system.

[0023] In related technologies, photovoltaic (PV) systems utilize PV brackets to fix PV modules onto building rooftops, facades, and other mounting surfaces, ensuring the modules are stably oriented towards the light source and guaranteeing stable operation of the PV system. However, existing PV bracket and module installation processes are numerous, typically requiring a large number of skilled installation workers, resulting in low assembly efficiency and reduced practicality of the PV system.

[0024] Understandably, most existing photovoltaic (PV) mounting systems involve installing support plates, support rods, and other support bases on building rooftops or facades, placing the PV modules on top of the support bases, and then attaching clamping blocks to the support bases to secure the PV module frames, achieving stable assembly of the PV modules on the PV mounting system. However, this installation process involves numerous steps, and in vertical installation environments such as building facades, workers are required to stabilize the PV modules on the support bases before installing the clamping blocks to secure them. This necessitates a large number of skilled workers to complete the installation, resulting in low assembly efficiency and reduced practicality and reliability of the PV mounting system. To address these issues, this application proposes a PV mounting system 100.

[0025] Please see Figure 1 , Figure 2 and Figure 7 In one embodiment of this application, the photovoltaic bracket 100 includes a bracket body 10 and a limiting structure 30. The bracket body 10 includes at least two supporting beams 11, which are spaced apart on the mounting surface 400. The side of the supporting beams 11 is provided with fixing grooves 111, and the fixing grooves 111 of two adjacent supporting beams 11 are arranged opposite each other to accommodate the opposite two sides of the photovoltaic module 200. The limiting structure 30 is connected to the supporting beams 11 and is used to limit and fix the photovoltaic module 200.

[0026] In this application, the support body 10 can have at least two supporting beams 11 arranged side by side at intervals. The supporting beams 11 can be fixedly installed on the mounting surface 400 such as the building roof or building facade using a base 15. In this case, the base 15 can be a block structure or plate structure connected to the supporting beams 11 by snap-fit ​​or bolts. The base 15 can be fixedly installed on the mounting surface 400 using self-tapping screws or screws. Alternatively, the supporting beams 11 can also be fixedly installed on the mounting surface 400 by welding. A certain length of protrusion can be extended outward from the building roof or building wall, and the supporting beams 11 can be welded and fixed to the protrusion to achieve a stable assembly of the support body 10 on the mounting surface 400 and ensure the supporting force of the photovoltaic support 100 on the photovoltaic module 200.

[0027] The width of the fixing groove 111 provided on the side of the supporting beam 11 can be slightly larger than the thickness of the photovoltaic module 200. The distance between the fixing grooves 111 of two adjacent supporting beams 11 can be slightly larger than the distance between the two sides of the photovoltaic module 200. At the same time, the distance between the sides of two adjacent supporting beams 11 can be slightly smaller than the distance between the two sides of the photovoltaic module 200. This allows at least two supporting beams 11 to be stably installed on the mounting surface 400, and the photovoltaic module 200 can be better installed between the two adjacent supporting beams 11.

[0028] It should be noted that, as Figure 11 As shown, during the assembly process in one embodiment, the photovoltaic module 200 can be tilted at a certain angle relative to the mounting surface 400, so that one side of the photovoltaic module 200 is inserted into the fixing groove 111 of a support beam 11. Then, the photovoltaic module 200 is rotated in the direction toward the mounting surface 400. At this time, since the distance between the fixing grooves 111 of two adjacent support beams 11 is slightly larger than the distance between the two opposite sides of the photovoltaic module 200, the other opposite side of the photovoltaic module 200 can be stably moved to the side of another adjacent support beam 11, so that the side can be installed into the fixing groove 111 of another adjacent support beam 11. Since the distance between the sides of two adjacent support beams 11 is slightly smaller than the distance between the two opposite sides of the photovoltaic module 200, the two opposite sides of the photovoltaic module 200 can be installed into the fixing grooves 111 of two adjacent support beams 11 at the same time. This allows the photovoltaic module 200 to be pre-installed between two adjacent support beams 11 with a certain amount of mobility, realizing the convenient installation of the photovoltaic module 200 on the photovoltaic bracket 100.

[0029] like Figure 12 As shown, in another embodiment of the assembly process, a second opening 1111 can be provided at the end of the support beam 11, extending into the fixing groove 111. This allows the photovoltaic module 200 to be inserted and installed from the end of the support beam 11. The two opposite sides of the photovoltaic module 200 can be moved along the extension direction of the support beam 11 and inserted into the fixing grooves 111 of two adjacent support beams 11. The distance between the fixing grooves 111 of two adjacent support beams 11 is slightly larger than the distance between the two opposite sides of the photovoltaic module 200, so that the photovoltaic module 200 can be smoothly inserted between the two adjacent support beams 11. At the same time, the distance between the sides of two adjacent support beams 11 is slightly smaller than the distance between the two opposite sides of the photovoltaic module 200, which effectively prevents the photovoltaic module 200 pre-installed between the two adjacent support beams 11 from falling off, thus realizing convenient assembly of the photovoltaic module 200 on the bracket body 10.

[0030] The above are merely illustrative examples of some installation methods of photovoltaic module 200 on two adjacent support beams 11. In actual applications, other methods can also be used to pre-install photovoltaic module 200 on bracket body 10. This application does not limit the specific assembly method of photovoltaic module 200 and bracket body 10.

[0031] By opening fixing grooves 111 on the side of the overall support beam 11, the photovoltaic module 200 can be pre-installed by inserting its two opposite sides into the fixing grooves 111 of two adjacent support beams 11. Furthermore, by connecting and setting a limiting structure 30 on the supporting beam 11, the limiting structure 30 can be a bolt structure spaced apart from the fixing groove 111 on the supporting beam 11. By rotating the bolt structure, the bolt structure can be inserted into the fixing groove 111 and abut against the side of the photovoltaic module 200, thereby limiting and fixing the photovoltaic module 200 between two adjacent supporting beams 11. Alternatively, the limiting structure 30 can be a locking block 311 set in the fixing groove 111. The locking block 311 can be embedded in the gap between the side of the photovoltaic module 200 and the inner wall of the fixing groove 111, thereby limiting and fixing the photovoltaic module 200 between two adjacent supporting beams 11. Or, the limiting structure 30 can be a screw structure that passes through the supporting beam 11 and the side of the photovoltaic module 200 and connects the supporting beam 11 and the photovoltaic module 200, so that the photovoltaic module 200 is limited and fixed between two adjacent supporting beams 11 under the action of the limiting structure 30. Therefore, by using the limiting structure 30 in conjunction with the two adjacent supporting beams 11, the photovoltaic module 200 can be stably installed on the photovoltaic bracket 100, ensuring the stable support of the photovoltaic bracket 100 for the photovoltaic module 200, effectively preventing the photovoltaic module 200 from being detached from the photovoltaic bracket 100 by external forces, and achieving a more stable and reliable overall structural design for the photovoltaic system.

[0032] Therefore, by inserting the two opposite sidewalls of the photovoltaic module 200 into the fixing grooves 111 of the two adjacent supporting beams 11 to achieve the pre-installation of the photovoltaic module 200 on the bracket body 10, and then operating the limiting structure 30 to limit and fix the photovoltaic module 200, the photovoltaic module 200 and the photovoltaic bracket 100 can be installed without the cooperation of many people, reducing the labor cost required for assembly operations, which is conducive to more convenient assembly operations of the photovoltaic system, improving the assembly efficiency of the photovoltaic system, and making the photovoltaic bracket 100 of this application have better practicality and reliability.

[0033] The spacing between two adjacent support beams 11 can be designed according to the installation direction of the photovoltaic modules 200. For example... Figure 1 As shown, when the photovoltaic modules 200 are installed vertically side-by-side, the shorter side of the photovoltaic module 200 can be inserted into the fixing groove 111. That is, the shorter side of the photovoltaic module 200 can be extended to match the supporting beam 11. In this case, the spacing between two adjacent supporting beams 11 can be arranged according to the length of the longer side of the photovoltaic module 200, so that the photovoltaic bracket 100 better matches the installation requirements of the photovoltaic module 200. Alternatively, as... Figure 2As shown, when the photovoltaic module 200 is installed in a horizontal side-by-side manner, the photovoltaic module 200 can be installed into the fixing groove 111 with the longer side. That is, the long side of the photovoltaic module 200 can be extended and set in conjunction with the supporting beam 11. At this time, the spacing between two adjacent supporting beams 11 can be arranged according to the length of the short side of the photovoltaic module 200 so that the photovoltaic bracket 100 can better meet the installation requirements of the photovoltaic module 200.

[0034] In one embodiment of this application, by arranging at least two support beams 11 at intervals on the mounting surface 400, the spacing between two adjacent support beams 11 can be set to correspond to the size of the photovoltaic module 200. Using the fixing grooves 111 opened on the side of the support beams 11, the two opposite sides of the photovoltaic module 200 can be respectively installed into the fixing grooves 111 of the two adjacent support beams 11. The limiting structure 30 plays a certain limiting and fixing role for the photovoltaic module 200, so that the photovoltaic module 200 can be stably installed on the bracket body. By creating fixing slots 111 on the side of the overall support beam 11, construction workers can arrange the support beams 11 at certain intervals on the mounting surface 400, and then directly install the photovoltaic module 200 into the fixing slots 111 of two adjacent support beams 11. This allows the two adjacent support beams 11 to clamp the photovoltaic module 200, thus achieving pre-installation of the photovoltaic module 200. Then, a limiting structure 30 is operated on the support beam 11 to limit and fix the photovoltaic module 200 to the two adjacent support beams 11, thereby achieving a stable installation of the photovoltaic module 200 on the photovoltaic bracket 100. This eliminates the need for multiple construction workers to cooperate in the assembly work, effectively simplifying the installation process of the photovoltaic bracket 100 and the photovoltaic module 200, enabling more convenient assembly of the photovoltaic module 200 on the photovoltaic bracket 100, and improving the assembly efficiency and practicality of the photovoltaic system. See Figure 3 and Figure 4 In one embodiment of this application, the limiting structure 30 includes a first limiting member 31, which is connected to the supporting beam 11. One end of the first limiting member 31 can extend into the fixing groove 111 and abut against the side of the photovoltaic module 200.

[0035] In this embodiment, the first limiting member 31 can be a fastening structure such as a bolt or pin installed on the support beam 11. In this case, the first limiting member 31 with a bolt structure can pass through the hole in the support beam 11 that connects to the fixing groove 111 during rotation, so that one end of the first limiting member 31 can extend into the fixing groove 111 and abut against the side of the photovoltaic module 200. The first limiting member 31 with a pin structure can insert the pin into the fixing groove 111 on the support beam 11 and abut against the side of the photovoltaic module 200. Then the pin is fixedly installed on the support beam 11 by welding or snap-fitting, ensuring the fastening effect of the first limiting member 31 on the photovoltaic module 200.

[0036] By connecting and fixing the first limiting member 31 to the support beam 11, the first limiting member 31 can apply a certain fastening force to the photovoltaic module 200, which can better achieve the limiting and fixing of the photovoltaic module 200 between two adjacent support beams 11, prevent the photovoltaic module 200 from moving relative to the bracket body 10 when subjected to external force, and further improve the overall structural stability and reliability of the photovoltaic bracket 100.

[0037] See Figure 4 and Figure 8 In one embodiment of this application, the supporting beam 11 is provided with a receiving groove 113, the receiving groove 113 and the fixing groove 111 are spaced apart, and the supporting beam 11 is provided with a connecting hole 1113 connecting the receiving groove 113 and the fixing groove 111; the first limiting member 31 includes a locking block 311 and a fastening bolt 313, the locking block 311 is fixedly disposed in the receiving groove 113, the fastening bolt 313 is connected to the locking block 311, one end of the fastening bolt 313 passes through the connecting hole 1113 and extends into the fixing groove 111, and abuts against the side of the photovoltaic module 200.

[0038] In this embodiment, by providing a receiving groove 113 spaced apart from the fixing groove 111 on the supporting beam 11, and providing a connecting hole 1113 connecting the fixing groove 111 and the receiving groove 113, the position of the connecting hole 1113 can be set to correspond to the installation position of the photovoltaic module 200 on the supporting beam 11. Furthermore, by installing a locking block 311 in the receiving groove 113 and connecting a fastening bolt 313 to the locking block 311, the stable installation of the locking block 311 in the fixing groove 111 can achieve a stable connection between the first limiting member 31 and the supporting beam 11, so that the locking block 311 can provide a certain support for the fastening bolt 313, allowing the fastening bolt 313 to stably pass through the connecting hole 1113 and enter the fixing groove 111 to abut against the side of the photovoltaic module 200, ensuring the limiting and fixing effect of the first limiting member 31 on the photovoltaic module 200, and further improving the overall structural stability and reliability of the photovoltaic bracket 100.

[0039] The locking block 311 can be fixed in the receiving groove 113 by snap-fit ​​structure, welding, or using self-tapping screws or other structures. The opening of the receiving groove 113 can be set towards the mounting surface 400, so that the construction personnel can more easily install the first limiting member 31 on the outside of the photovoltaic bracket 100, further improving the ease of assembly between the photovoltaic bracket 100 and the photovoltaic module 200.

[0040] See Figure 4 and Figure 8 In one embodiment of this application, the inner wall of the receiving groove 113 is provided with a slot 1131, and one side of the locking block 311 is provided with a locking protrusion 3111, which is locked into the slot 1131.

[0041] In this embodiment, the cross-sectional shape of the slot 1131 can be T-shaped, C-shaped, triangular, or other shapes. In this case, the snap-fit ​​protrusion 3111 can be a protrusion structure that matches the cross-sectional shape of the slot 1131. The snap-fit ​​protrusion 3111 can be snap-fitted into the slot 1131 to achieve a stable assembly of the snap-fit ​​block 311 in the fixing groove 111, thereby further improving the overall structural stability and reliability of the photovoltaic bracket 100.

[0042] The slot 1131 can extend in the same direction as the receiving groove 113. By having a snap-fit ​​protrusion 3111 on one side of the snap-fit ​​block 311 snap-fitted and fixed in the slot 1131, the snap-fit ​​block 311 can be limited and slidably positioned within the receiving groove 113. This facilitates better movement of the snap-fit ​​block 311 according to the installation position of the photovoltaic module 200 on the support beam 11, ensuring that the snap-fit ​​block 311 can stably correspond to the installation of the photovoltaic module 200 and guaranteeing the stable positioning and fastening effect of the first limiting member 31 on the photovoltaic module 200. At the end of the support beam 11, a first opening 1133 can be provided to connect the fixing groove 111 and the slot 1131, allowing the snap-fit ​​block 311 to be installed from the end of the support beam 11 into the fixing groove 111 through the first opening 1133, thus achieving convenient assembly of the photovoltaic bracket 100.

[0043] See Figures 7 to 9 In one embodiment of this application, the end of the supporting beam 11 is provided with a first opening 1133 that connects the receiving groove 113 and the slot 1131; the bracket body 10 also includes a stop block 13, one side of the stop block 13 is provided with a fixing rib 131, the fixing rib 131 is inserted into the slot 1131, and the stop block 13 can open or close the first opening 1133.

[0044] In this embodiment, the supporting beam 11 can be designed as an integrally cast steel structure. A first opening 1133 can be formed at the end of the supporting beam 11 to connect the fixing groove 111 and the slot 1131. The first opening 1133 allows the slot 311 to be more easily inserted into the fixing groove 111 and moved within the fixing groove 111 to the installation position of the photovoltaic module 200. The operating fastening bolt 313 passes through the connecting hole 1113 and enters the fixing groove 111 to abut against the side of the photovoltaic module 200, ensuring the stable positioning effect of the first limiting member 31 on the photovoltaic module 200.

[0045] After the locking block 311 is stably installed into the fixing slot 111, a stop block 13 can be installed at the end of the supporting beam 11. The stop block 13 covers the first opening 1133, thereby better preventing the locking block 311 from falling out of the supporting beam 11 from the first opening 1133, and further improving the overall structural stability and reliability of the photovoltaic bracket 100. Specifically, the stop block 13 can be provided with a fixing rib 131 on one side corresponding to the cross-sectional shape of the locking slot 1131. This allows the stop block 13 to insert the fixing rib 131 into the locking slot 1131 at the end of the supporting beam 11, and to abut against the end face of the supporting beam 11, so that the stop block 13 can stably close the first opening 1133. The use of the fixing rib 131 and the locking slot 1131 for insertion and fixation allows the stop block 13 to be more easily installed and removed from the supporting beam 11, further improving the assembly convenience of the photovoltaic bracket 100.

[0046] When the slot 1131 adopts a "T" shaped cross-section, the height of the slot 1131 can be slightly less than the overall height of the fixing rib 131. This allows the fixing rib 131 to have a partial structural protrusion at the opening of the slot 1131 when inserted into it, so that the fixing rib 131 can be fixedly installed in the slot 1131 in an interference fit manner. This is beneficial to improve the connection stability and reliability between the stop block 13 and the support beam 11.

[0047] See Figure 4 In one embodiment of this application, the photovoltaic bracket 100 further includes a spacer 50, which is disposed in the fixing groove 111 and connected to the side of the photovoltaic module 200. The first limiting member 31 abuts against the spacer 50.

[0048] In this embodiment, by using spacers 50 on the side of the photovoltaic module 200, the spacers 50 can buffer the fastening force applied to the photovoltaic module 200 by the first limiting member 31, avoid local stress concentration on the photovoltaic module 200, so that the photovoltaic module 200 can be installed more stably on the photovoltaic bracket 100, better prevent damage to the photovoltaic module 200, and ensure the stable operation of the photovoltaic system.

[0049] During assembly, the spacer 50 can be first connected and installed on the side of the photovoltaic module 200, and then the photovoltaic module 200 with the spacer 50 can be pre-installed onto the bracket body. This allows the first limiting member 31, when assembled on the support beam 11, to better abut against the spacer 50. The spacer 50 cushions the fastening effect of the first limiting member 31, achieving a reliable abutment effect of the first limiting member 31 on the photovoltaic module 200. This allows the photovoltaic module 200 to be better positioned between two adjacent support beams 11, further improving the overall structural stability and reliability of the photovoltaic bracket 100. The spacer 50 can be fixed to the side of the photovoltaic module 200 by adhesive, or it can be sleeved on the side of the photovoltaic module 200 and secured with clips, improving the connection stability and reliability between the spacer 50 and the photovoltaic module 200.

[0050] See Figures 5 to 7 In one embodiment of this application, the limiting structure 30 includes a second limiting member 33, which is disposed in the fixing groove 111 and is used to limit and separate two adjacent photovoltaic modules 200.

[0051] In this embodiment, at least two photovoltaic modules 200 can be installed side-by-side between two adjacent support beams 11 to enable the photovoltaic system to fully absorb and convert more light energy and ensure the stable operation of the photovoltaic system. Multiple photovoltaic modules 200 arranged side-by-side between two adjacent support beams 11 typically need to maintain a certain gap to avoid mutual compression and damage. By including a second limiting member 33 in the limiting structure 30, which can be a soft material structure with a certain elasticity, such as a rubber block 13 or a silicone block 13, and installing the second limiting member 33 in the fixing groove 111, the second limiting member 33 can be positioned between two adjacent photovoltaic modules 200. This allows the second limiting member 33 to provide a certain limiting effect on the photovoltaic modules 200 along the extension direction of the support beams 11, enabling the limiting structure 30 to more stably fix the photovoltaic modules 200 between two adjacent photovoltaic modules 200, preventing the photovoltaic modules 200 from moving or shaking relative to the photovoltaic bracket 100 under external forces. Meanwhile, under the separation effect of the second limiting member 33, two adjacent photovoltaic modules 200 can maintain a certain distance, better avoid damage to the photovoltaic modules 200, and further improve the overall structural stability and reliability of the photovoltaic bracket 100.

[0052] The second limiting member 33 can be fastened in the fixing groove 111 using screws, self-tapping screws or other structures, or it can be glued to the inner wall of the fixing groove 111 using adhesive, or it can be snapped into the fixing groove 111 using a buckle to fix the second limiting member 33, thereby achieving stable installation of the second limiting member 33 on the supporting beam 11.

[0053] See Figure 3 and Figure 7 In one embodiment of this application, the bracket body 10 further includes a base 15, which is connected to the support beam 11 and fixedly connected to the mounting surface 400.

[0054] In this embodiment, the bracket body 10 can be installed on the mounting surface 400 such as the building roof or building facade using the base 15. The base 15 can be fastened to the mounting surface 400 using fastening structures such as self-tapping screws, screws, and bolts. Alternatively, a connecting anchor point can be raised on the mounting surface 400, and the base 15 can be welded to the connecting anchor point or connected by a flange, so that the base 15 can be stably installed on the mounting surface 400.

[0055] A mutually engaging connection structure can be provided between the base 15 and the supporting beam 11 to improve the stability and reliability of the connection between the base 15 and the supporting beam 11, so that the photovoltaic bracket 100 can more stably support and carry the photovoltaic module 200. Specifically, a snap-fit ​​groove structure can be provided on the base 15 to engage with the supporting beam 11, allowing the supporting beam 11 to be locked onto the base 15, achieving a stable connection between the base 15 and the supporting beam 11; alternatively, screws, bolts, or other fastening structures can be used to fix the supporting beam 11 onto the base 15, achieving a stable connection between the base 15 and the supporting beam 11; or, the base 15 and the supporting beam 11 can be welded together to ensure a stable connection between the supporting beam 11 and the base 15.

[0056] By setting the base 15 to be installed on the mounting surface 400 and then connecting the support beam 11 to the base 15, the base 15 can be installed at a fixed point according to the configuration requirements of the photovoltaic module 200 on the mounting surface 400. This makes it easier to install the support beam 11 onto the base 15, thus enabling the photovoltaic bracket 100 to be fixedly installed on the mounting surface 400. This eliminates the need for construction personnel to lift the heavy support beam 11 to find a positioning point on the mounting surface 400 for installation, further improving the assembly convenience of the photovoltaic bracket 100.

[0057] See Figure 7 and Figure 10 In one embodiment of this application, two flanges 115 are provided at intervals on one side of the supporting beam 11, and two fastening grooves 151 are provided on the base 15, with the two flanges 115 respectively engaging in the two fastening grooves 151.

[0058] In this embodiment, the side of the support beam 11 facing the mounting surface 400 can be bent outward to form two flanges 115, and the two flanges 115 extend and protrude in opposite directions. At this time, the base 15 can be provided with two opposite fastening grooves 151, so that the two fastening grooves 151 are respectively matched with the two flanges 115. Therefore, the two flanges 115 can be respectively snapped into the two opposite fastening grooves 151, realizing the matching snapping of the base 15 and the support beam 11, further improving the connection stability and reliability of the base 15 and the support beam 11.

[0059] See Figure 7 and Figure 9 In one embodiment of this application, the end of the support beam 11 is provided with a second opening 1111 that connects to the fixing groove 111, and the bracket body 10 also includes a stop block 13, which is connected to the support beam 11 and can open or close the second opening 1111.

[0060] In this embodiment, the supporting beam 11 can be made of integrally cast steel. In this case, a second opening 1111 can be formed at the end of the supporting beam 11 to connect the fixing groove 111. Then, during the assembly process, the photovoltaic module 200 can be inserted from the end of the supporting beam 11 through the second opening 1111 and inserted between two adjacent supporting beams 11, so that the two opposite sides of the photovoltaic module 200 can move along the extension direction of the supporting beam 11 and be inserted into the fixing groove 111, thereby realizing the matching assembly of the photovoltaic module 200 and the photovoltaic bracket 100 and further improving the assembly convenience of the photovoltaic module 200 and the photovoltaic bracket 100.

[0061] At this point, by utilizing the detachable installation of the stop block 13 at the end of the supporting crossbeam 11, the stop block 13 can be installed on the supporting crossbeam 11 after the photovoltaic module 200 is pre-installed on the bracket body 10. The stop block 13 abuts against the end face of the supporting crossbeam and covers the second opening 1111, thus closing the second opening 1111. This helps prevent the photovoltaic module 200 from passing through the second opening 1111 and detaching from the supporting crossbeam 11, achieving a stable installation of the photovoltaic module 200 on the photovoltaic bracket 100 and further improving the overall structural stability and reliability of the photovoltaic bracket 100. The ends of the stop block 13 and the supporting crossbeam 11 can be provided with a mutually engaging snap-fit ​​structure, allowing the stop block 13 to be snapped and fixed to the supporting crossbeam 11. Alternatively, screws or bolts can be used to connect the stop block 13 and the supporting crossbeam 11, enabling convenient installation and removal of the stop block 13 from the supporting crossbeam 11.
