[0034] In the related art, purlins are widely used in photovoltaic brackets. Purlins can usually be used to connect and support photovoltaic modules or to connect multiple bracket columns to form a whole, etc., to ensure the stability of the overall structure of the photovoltaic bracket. However, in order to facilitate the transportation of purlins, the length of purlins is mostly short when they are produced. Purlins can be spliced and fixed by using connectors at the construction site. Usually, holes can be opened at the ends of the purlins, and the connectors can be fastened to the purlins and connectors by passing bolts through the holes in the purlins, thereby achieving stable splicing and extension of multiple purlins, and better meeting the layout requirements of a certain range of photovoltaic brackets. However, by opening holes in the purlins and fastening the connectors and purlins with bolts, the construction and installation process of the purlins is easily complicated, which reduces the installation efficiency of the photovoltaic bracket. In response to the above problems, the present application proposes a purlin structure 1000.

[0035] See also Figures 1 to 8 In one embodiment of the present application, the purlin structure 1000 includes a first purlin 400, a second purlin 600 and a connecting assembly 200. The connecting assembly 200 includes a socket 100 and a fastener 50. A fixing cavity is provided in the socket 100. Plug interfaces communicating with the fixing cavity are provided on opposite sides of the socket 100. One end of the first purlin 400 and one end of the second purlin 600 are respectively inserted into the fixing cavity through the two plug interfaces. The fastener 50 is connected to the socket 100 and abuts against and fixes the first purlin 400 and the second purlin 600.

[0036] It is understood that the photovoltaic bracket can be installed and fixed with purlins on the top of the support frame. The purlins can be used to connect multiple support frames arranged side by side, so that the photovoltaic bracket can form a larger bearing surface on the top of the support frame, ensuring that the photovoltaic bracket can stably support and install the photovoltaic modules. In order to better connect multiple support frames with a larger span, the connecting assembly 200 can be used to connect adjacent first purlins 400 and second purlins 600, so that multiple purlins can be spliced end to end and extended. This allows the photovoltaic bracket to better meet the layout area requirements of the photovoltaic power station and ensure the stable operation of the photovoltaic power station.

[0037] In the present application, the connection assembly 200 may include a socket 100 and a fastener 50. The socket 100 may be formed as follows: Figure 6 The one-piece sleeve structure shown in FIG. 1 may be provided; or Figure 2 and Figure 4The split combined splint structure shown is set up, etc., a fixed cavity of a certain space can be formed in the socket 100, and plug interfaces connected to the fixed cavity are respectively formed on the opposite sides of the socket 100, so that the size of the fixed cavity and the plug interface can be made larger than the size of the first purlin 400 and the second purlin 600, so that one end of the first purlin 400 and one end of the second purlin 600 can respectively pass through the two plug interfaces and be inserted into the fixed cavity. At this time, by connecting and setting the fastener 50 on the socket 100, the fastener 50 can be used to press and fix the first purlin 400 and the second purlin 600 in the fixed cavity, so that the outer walls of the first purlin 400 and the second purlin 600 are in contact with the inner wall of the fixed cavity, which is beneficial for the socket 100 to play a certain role in increasing the purlin wall thickness, thereby achieving structural reinforcement at the connection node of the first purlin 400 and the second purlin 600, and under the pressing action of the fastener 50, the friction force between the first purlin 400 and the second purlin 600 and the socket 100 can be better increased, preventing the first purlin 400 and the second purlin 600 from detaching from the socket, thereby achieving a stable splicing effect of the purlin structure 1000, and effectively improving the connection stability and reliability of the connection component 200 and the first purlin 400 and the second purlin 600.

[0038] The fastener 50 can be a bolt structure that is threadedly fixed to the outer wall of the socket 100, and the fastener can be tightened on the outer wall of the socket 100 to achieve the fastening of the first purlin 400 and the second purlin 600; or the fastener 50 can be a pin structure that is inserted into the outer wall of the socket 100, and the pin structure can be used to pass through the through hole on the outer wall of the socket 100 into the fixing cavity to press against the first purlin 400 and the second purlin 600. , and then utilize the elastic structure of the plug to abut against the through-hole wall of the socket 100, or utilize colloid to bond the plug and socket 100. Alternatively, the fastener 50 can be designed as a triangular wedge block, so that the fastener 50 can be passed through the insertion interface and positioned between the first purlin 400 and the second purlin 600 and the inner wall of the fixing cavity. Then, a hammer can be used to strike the fastener 50 so that the fastener 50 abuts against the inner wall of the fixing cavity and the outer wall of the first purlin 400 and the outer wall of the second purlin 600. The abutting action of the fastener 50 can effectively ensure the stable connection between the connecting assembly and the first purlin 400 and the second purlin 600, so that the purlin structure 1000 can form a stable integrated structure, ensuring the stable end-to-end splicing of multiple purlins on the photovoltaic bracket.

[0039] By using the connection assembly 200 to securely connect the first purlin 400 and the second purlin 600, the friction between the structures can be utilized to achieve a secure connection of the purlin structure 1000. This allows the purlins to be transported in sections to the construction site for splicing and installation, effectively reducing the number of purlin openings and assembly steps, enabling a more efficient photovoltaic bracket assembly process and effectively improving the assembly efficiency of the photovoltaic bracket. Simultaneously, the number of purlin openings is reduced, and the tight fit of the socket 100 with the first purlin 400 and the second purlin 600 can further enhance the structural strength of the purlin connection, thereby providing the purlin structure 1000 with greater structural stability and effectively improving the practicality and reliability of the purlin structure 1000.

[0040] In one embodiment of the present application, one end of the first purlin 400 and one end of the second purlin 600 are inserted into the fixed cavity through the plug-in ports on both sides of the socket 100, and the first purlin 400 and the second purlin 600 are fixed in the fixed cavity using a fastener 50 connected to the socket 100. This allows the connection assembly 200 to stably connect the first purlin 400 and the second purlin 600 to form a whole, effectively achieving the splicing and extension of the purlins of the photovoltaic bracket so that the photovoltaic bracket can more stably install and support multiple photovoltaic modules, thereby ensuring the stable and reliable operation of the photovoltaic power station. The first purlin 400 and the second purlin 600 are fixed in the fixing cavity by using fasteners 50. There is no need to open mounting holes on the first purlin 400 and the second purlin 600 and then install them through connecting components 200 such as bolts or snaps. This is conducive to better improving the installation convenience and efficiency of the photovoltaic bracket. At the same time, it can better avoid damaging the overall structure of the purlin, better improve the stability and reliability of the purlin structure 1000, and ensure that the photovoltaic bracket firmly supports and fixes the photovoltaic components.

[0041] See Figures 1 to 5 In one embodiment of the present application, the socket includes a connecting member 10 and a fixing member 30. The connecting member 10 is provided with a snap-fit groove 10a, and the inner wall of the snap-fit groove 10a abuts against the outer wall of the first purlin and the outer wall of the second purlin; the fixing member 30 is connected to the connecting member 10 and encloses the connecting member to form a fixing cavity.

[0042] The socket may include a connector 10 and a fixing member 30. The connector may be arranged in a C-shaped block structure so that a clamping groove 10a may be formed on one side of the connector 10. The size and shape of the clamping groove 10a may be set to correspond to the size and shape of the ends of the first purlin 400 and the second purlin 600, so that the ends of the first purlin 400 and the second purlin 600 may be respectively clamped into the clamping groove 10a of the connector 10, so that the inner wall of the clamping groove 10a cooperates and abuts with the outer wall of the first purlin 400 and the outer wall of the second purlin 600, thereby realizing the clamping and fixing of the first purlin 400 and the second purlin 600 by the connector 10. The fixing member 30 can be a cover plate connected and fixed with the connecting member 10 or a "C"-shaped clip structure. The fixing member 30 can be used to cover at least a portion of the slot 10a of the clamping slot 10a and enclose the connecting member to form a fixing cavity, so that the ends of the first purlin 400 and the second purlin 600 are wrapped under the fixing action of the fixing member 30 and the connecting member 10, and the first purlin 400 and the second purlin 600 are fixed by the fastener 50, so as to realize the stable connection of the connecting assembly 200 to the first purlin 400 and the second purlin 600.

[0043] By using the connecting piece 10 to clamp two adjacent purlins, the first purlin 400 and the second purlin 600 can be installed and fixed using the socket 100 with a split structure. This is conducive to butting the first purlin 400 and the second purlin 600 end to end and then installing the connecting assembly 200 to splice the first purlin 400 and the second purlin 600, thereby achieving a more convenient and reliable installation method for the purlin structure 1000, further improving the assembly convenience and practicality of the purlin structure 1000.

[0044] In some embodiments, the fastener 50 can be connected to the fixing member 30, in which case the fastener 50 can be pressed against the side of the first purlin 400 and the second purlin 600 facing the inner wall of the fixing member 30, and the first purlin 400 and the second purlin 600 can be firmly abutted and fixed to the connecting member 10 under the action of the fastener 50; or, the fastener 50 can be connected to the connecting member 10, in which case the fastener 50 can be pressed against the side of the first purlin 400 and the second purlin 600 facing away from the fixing member 30, and the first purlin 400 and the second purlin 600 can be firmly abutted and fixed to the fixing member 30 under the action of the fastener 50; or, the fastener 50 can be connected to the position where the fixing member 30 and the connecting member 10 are connected, so that the fastener 50 can play a certain role in connecting the fixing member 30 and the connecting member 10, thereby better improving the overall structural stability and reliability of the purlin structure 1000.

[0045] See Figure 1 、 Figure 3 and Figure 5In one embodiment of the application, the connecting member 10 is provided with a first bolt hole 131, and the fixing member 30 is provided with a second bolt hole 3311. The second bolt hole 3311 is connected to the first bolt hole 131. The fastener 50 is a fastening bolt that passes through the first bolt hole 131 and the second bolt hole 3311 and connects the fixing member 30 and the connecting member 10.

[0046] In this embodiment, the fastener 50 can be in the form of a fastening bolt. In this case, a first bolt hole 131 can be provided on the connecting member 10, and a second bolt hole 3311 corresponding to and communicating with the first bolt hole 131 can be provided on the fixing member 30. By providing internal threads on the inner walls of the first bolt hole 131 and the second bolt hole 3311, the fastening bolt can be threadedly engaged with the connecting member 10 and the fixing member 30 when passing through the first bolt hole 131 and the second bolt hole 3311, respectively. This ensures the stability and reliability of the connection between the fixing member 30 and the connecting member 10 under the action of the fastening bolt, thereby achieving stable assembly of the purlin structure 1000. The use of fastening bolts for installation also facilitates the convenient installation of the fastener 50 with the connecting member 10 and the fixing member 30, further improving the assembly convenience and practicality of the purlin structure 1000.

[0047] In addition, the first bolt hole 131 on the connecting member 10 can be set through the inner wall of the clamping groove 10a, so that one end of the fastening bolt can pass through the first bolt hole 131 and be exposed on the inner wall of the clamping groove 10a, which is conducive to using the end of the fastening bolt to press against the outer walls of the first purlin 400 and the second purlin 600 in the clamping groove 10a, so that the purlin structure 1000 can use the coordinated fastening effect of the fastener 50, the fixing member 30 and the connecting member 10 to increase the abutting friction between the fastener 50 and the first purlin 400 and the second purlin 600, which is conducive to better preventing the separation of the purlin structure 1000, realizing the stable fixing effect of the connecting assembly 200 on the first purlin 400 and the second purlin 600, and further improving the structural stability and reliability of the purlin structure 1000.

[0048] In one embodiment of the present application, the connection assembly 200 further includes a positioning member 70 . At least a portion of the positioning member 70 is disposed in the fixing cavity and abuts against end surfaces of the first purlin 400 and the second purlin 600 .

[0049] In this embodiment, the positioning member 70 can be a baffle structure arranged in the fixed cavity; or, the positioning member 70 can have a partial structure that is passed through the socket 100, so that the positioning member 70 can extend the partial structure into the fixed cavity. Furthermore, under the action of the positioning member 70, the first purlin 400 and the second purlin 600 can abut the positioning member 70 when their ends are clamped in the fixed cavity, thereby realizing the installation limit of the first purlin 400 and the second purlin 600 in the fixed cavity, preventing the first purlin 400 and the second purlin 600 from abutting against each other, which has a certain probability of causing the first purlin 400 or the second purlin 600 to detach from the socket 100.

[0050] The positioning member 70 can be disposed in the center of the fixing cavity, allowing the ends of the first purlin 400 and the second purlin 600 to be inserted into the fixing cavity to a certain length before abutting against the positioning member 70. This effectively achieves the installation limit of the two purlins in the fixing cavity, ensures that the first purlin 400 and the second purlin 600 can have a certain splicing length in the fixing cavity, and prevents the first purlin 400 or the second purlin 600 from being separated from the socket 100 due to a short length connected to the fixing cavity. This helps to further improve the stability and reliability of the connection between the connecting assembly 200 and the first purlin 400 and the second purlin 600. At the same time, the positioning member 70 can be used during construction and installation to achieve more convenient limited installation of the first purlin 400 and the second purlin 600, reducing the positioning and measurement of the first purlin 400 and the second purlin 600 during installation, further improving the assembly convenience and reliability of the purlin structure 1000.

[0051] See Figure 2 、 Figure 4 and Figure 6 In one embodiment of the present application, the positioning member 70 includes a limiting plate 71 and a supporting connecting plate 73. Part of the structure of the limiting plate 71 passes through the connecting member 10 and the fixing member 30 and is arranged in the clamping groove 10a; the supporting connecting plate 73 connects the limiting plate 71, and the fastener 50 connects the supporting connecting plate 73 and the socket.

[0052] In this embodiment, the socket 100 can be provided with a through hole on the outer wall corresponding to the size and shape of the limit plate 71, so that the limit plate 71 of the positioning member 70 can pass through the through hole on the socket 100 and enter the fixed cavity. At this time, the support connecting plate 73 can abut on the outer wall of the socket 100, so that the limit plate 71 can be stably supported under the action of the support connecting plate 73, so that the limit plate 71 can be stably set in the central area of the fixed cavity to abut the end faces of the first purlin 400 and the second purlin 600, thereby realizing convenient limit installation of the connecting component 200 and the first purlin 400 and the second purlin 600.

[0053] When the fasteners 50 are configured using bolts or latches, the purlin structure 1000 can utilize the fasteners 50 to simultaneously connect and secure the support link plate 73 and the socket. This simplifies the assembly process of the purlin structure 1000 and further enhances the assembly convenience and practicality of the purlin structure 1000. In this case, when the fasteners 50 are secured by fastening bolts through bolt holes on the outer wall of the socket 100, corresponding bolt holes can be provided on the support link plate 73, allowing the fasteners 50 to sequentially pass through the bolt holes of the socket 100 and the support link plate 73 to securely secure the support link plate 73 and the socket 100. This allows for more stable and convenient assembly of the purlin structure 1000 and further enhances the practicality and reliability of the purlin structure 1000.

[0054] In addition, when the socket 100 adopts a structural setting in which the connecting member 10 and the fixing member 30 are matched and connected, a avoidance hole with a size and shape corresponding to the limit plate 71 can be provided on the connecting member 10, and the fixing member 30 can be provided with a hole structure that is connected to the avoidance hole of the connecting member 10, or the fixing member 30 adopts a structure in which two connecting members 10 are respectively socketed side by side, so that the two structures of the fixing member 30 have a certain gap, so that the limit plate 71 of the positioning member 70 can stably pass through the socket 100 and enter the fixed cavity, thereby realizing a stable abutment and limiting effect on the first purlin 400 and the second purlin 600 in the fixed cavity.

[0055] See Figures 1 to 3 In one embodiment of the present application, a limiting groove 3313 is provided on the outer wall of the socket 100 , and at least a portion of the structure of the supporting connecting plate 73 is provided in the limiting groove 3313 .

[0056] In this embodiment, the sleeve 100 can be provided with a limiting groove 3313 on the outer wall corresponding to the size and shape of the support link 73, so that the positioning member 70 can be set in the limiting groove 3313 when the support link 73 is abutted and installed on the outer wall of the sleeve 100, and the inner wall of the limiting groove 3313 is used to abut against part of the outer wall of the support link 73 to realize the limited installation of the positioning member 70, which is beneficial to prevent the positioning member 70 from shifting after installation, ensure the stable assembly of the first purlin 400 and the second purlin 600 by the connecting component 200, and further improve the overall structural stability and reliability of the purlin structure 1000.

[0057] See Figures 2 to 5 In one embodiment of the present application, the connecting member 10 includes a first plate 11 and two oppositely arranged second plates 13. The first plate 11 connects the two second plates 13 and encloses them to form a snap-in groove 10a. The fixing member 30 clamps the two second plates 13 and abuts against at least part of the first plate 11.

[0058] In this embodiment, since purlins are mostly constructed of steel structures such as channel steel or square steel, the connector 10 is formed by connecting the first plate 11 and two oppositely disposed second plates 13. This allows the connector 10 to have a C-shaped steel structure. This allows the connector 10 to better fit and engage with the outer walls of the first purlin 400 and the second purlin 600 using the engaging grooves 10a, thereby achieving a tight fit between the connecting assembly 200 and the first purlin 400 and the second purlin 600. The fixing member 30 can be configured in the form of a clip, so that the fixing member 30 abuts against the two second plates 13 and at least a portion of the first plate 11 to clamp and secure the connector 10, ensuring a stable connection and fixation between the fixing member 30 and the connector 10, and achieving wrapping and fixation of the fixing member 30 and the connector 10 with the first purlin 400 and the second purlin 600, further improving the structural stability and reliability of the purlin structure 1000.

[0059] See Figures 2 to 5 In one embodiment of the present application, the fixing member 30 includes a first fixing portion 31 and two second fixing portions 33. The second fixing portion 33 includes a cross block 331 and a side block 333. The side block 333 is bent and connected to one side of the cross block 331. The cross blocks 331 of the two second fixing portions 33 are arranged opposite to each other. The first fixing portion 31 connects the two cross blocks 331 on the side facing away from the side blocks. The cross block 331 abuts against the outer wall of the second plate 13, and the side block 333 abuts against the outer wall of the first plate 11.

[0060] In this embodiment, the cross block 331 and the side block 333 can be connected to form a structure similar to the shape of a figure 7, so that the fixing member 30 can use the second fixing portion 33 to hook the second plate 13 and the first plate 11 of the connecting member 10, and then use the first fixing portion 31 to connect the cross block 331 of the two second fixing portions 33, so that the fixing member 30 can be stably wrapped and sleeved on the connecting member 10, realizing the coordinated fixed installation of the fixing member 30 and the connecting member 10, and further improving the connection stability and reliability of the fixing member 30 and the connecting member 10. At this time, the first fixing portion 31 can be arranged at a relative interval to the first plate 11 of the connecting member 10, so that the first fixing portion 31 can stably abut the outer walls of the first purlin 400 and the second purlin 600 exposed at the notch of the snap-in groove 10a, thereby realizing the wrapping and fixing of the outer walls of the ends of the first purlin 400 and the second purlin 600 by the socket 100, and then realizing the reinforced splicing of the ends of the first purlin 400 and the second purlin 600 by the purlin structure 1000, ensuring the stable splicing and extension of multiple purlins on the photovoltaic bracket, and further improving the practicality and reliability of the purlin structure 1000.

[0061] See Figure 3 and Figure 5In one embodiment of the present application, the second plate 13 is provided with one of the guide grooves 133 or the guide protrusions 3315 on the side facing the cross block 331, and the cross block 331 is provided with the other of the guide grooves 133 or the guide protrusions 3315 on the side facing the second plate 13, and the guide grooves 133 and the guide protrusions 3315 are arranged in a clamping manner.

[0062] In this embodiment, by providing a guide groove 133 on the second plate 13 and providing a guide protrusion 3315 that cooperates with the guide groove 133 on the outer periphery of the cross block 331; or, providing a guide protrusion 3315 on the second plate 13 and providing a guide groove 133 on the outer periphery of the cross block 331, when the fixing member 30 and the connecting member 10 are installed, the guide protrusion 3315 can be used to cooperate and snap into the guide groove 133 to achieve limited sleeve installation of the fixing member 30 and the connecting member 10, which is beneficial to avoid displacement of the fixing member 30 during the process of sliding and sleeve connecting the connecting member 10, further improving the connection stability and reliability of the fixing member 30 and the connecting member 10, and achieving more stable, reliable and convenient assembly of the purlin structure 1000.

[0063] See Figures 1 to 3 In one embodiment of the present application, the connecting assembly 200 includes two fixing members 30 , and the two fixing members 30 are connected to the connecting member 10 side by side.

[0064] In this embodiment, the connecting component can adopt a structural setting of two fixing members 30. During the installation process, the two fixing members 30 can be pre-installed and sleeved on the first purlin 400 and the second purlin 600 respectively. After the first purlin 400 and the second purlin 600 are clamped by the connecting member 10, the two fixing members 30 are moved close to each other on the first purlin 400 and the second purlin 600 and connected to the connecting member 10 respectively, so as to realize the matching sleeve installation of the fixing members 30 and the connecting member 10. The installation method of the two fixing members 30 being sleeved side by side can reduce the matching installation length of the fixing members 30 and the connecting member 10, which is conducive to better improving the assembly convenience and practicality of the purlin structure 1000.

[0065] See Figures 1 to 3 In one embodiment of the present application, an anti-slip structure 135 is provided on the inner wall of the fixing cavity, and the anti-slip structure 135 abuts against the outer wall of the first purlin 400 and the outer wall of the second purlin 600 .

[0066] In this embodiment, an anti-slip structure 135 is provided on the inner wall of the fixed cavity. The anti-slip structure 135 may be an anti-slip protrusion, an anti-slip rib, etc. The friction force between the socket 400 and the first purlin 400 and the second purlin 600 can be better increased under the action of the anti-slip structure 135, which is beneficial to better prevent the first purlin 400 and the second purlin 600 from being pulled out of the socket 100, thereby achieving a more stable and reliable installation and fixation of the connecting assembly 200 and the first purlin 400 and the second purlin 600, ensuring the structural stability of the photovoltaic bracket, and further improving the practicality and reliability of the purlin structure 1000.
