[0002] The main function of the purlin is to connect and fix the photovoltaic module on the main shaft of the photovoltaic bracket. Therefore, as a photovoltaic connector, the purlin is more and more widely used in the photovoltaic field. The existing conventional purlin is in a U shape, that is, the opening of the U shape faces upward towards the photovoltaic module, so that only part of the component frame is located on the installation surface of the purlin and part of the component cavity is suspended. Although the U-shaped purlin has more advantages in terms of production cost and processing ease, when combined with the photovoltaic module, the photovoltaic module can bear less wind pressure, and the U-shaped purlin is prone to bending deformation in strong winds, so it cannot adapt to the current trend of large components. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a photovoltaic connection component and a photovoltaic bracket, so that the photovoltaic module can bear greater wind pressure and reduce the risk of purlin bending deformation.
[0004] To achieve the above purpose, the utility model adopts the following technical solution 1: A photovoltaic connection component is used to fixedly install a photovoltaic module on the main shaft of a photovoltaic bracket. The extending direction of the main shaft is defined as the front-back direction, and the cross-section of the main shaft also has an up-down direction and a left-right direction. The up-down direction, the left-right direction, and the front-back direction are perpendicular to each other pairwise. The photovoltaic connection component includes a purlin for connecting with the photovoltaic module and a third connector for fixing with the main shaft. The purlin includes a top plate and bending plates extending downward from the top plate. There are two bending plates, which are respectively located on the front and rear sides of the top plate. When looking at the purlin from one end to the other end along the left-right direction, an opening is formed between the two bending plates and the top plate. The opening faces away from the top plate and towards the third connector.
[0005] As a further improved technical solution 1 of the utility model, the top plate includes an end plane. The end plane includes a first plane at the left end and a second plane at the right end. The first plane and the second plane are coplanar and are used to support the photovoltaic module.
[0006] As a first further improved technical solution of the present utility model, it further includes a first connecting member for fixing to the photovoltaic module. The purlin is located between the first connecting member and the third connecting member. The first connecting member includes a pressing block and a fastening member. One end of the pressing block is provided with a first hole, and the end plane is provided with a second hole. The fastening member passes through the first hole and the second hole. The other end of the pressing block is pressed above the frame of the photovoltaic module. Through the cooperation of the pressing block and the fastening member, the photovoltaic module is positioned and connected to the purlin.
[0007] As a first further improved technical solution of the present utility model, the top plate includes a third plane located in the middle and parallel to the first plane and the second plane. The third connecting member is positioned and connected to the third plane. In terms of the up and down direction, the height value of the third plane relative to the main axis is lower than the height values of the first plane and the second plane relative to the main axis, and / or, in terms of the front and back direction, the width value of the third plane is smaller than the width values of the first plane and the second plane.
[0008] As a first further improved technical solution of the present utility model, the bending plate is stamped downward from the top plate. The position of the bending plate corresponding to the third plane has two grooves formed by stamping upward from the bottom and arranged corresponding to the front and back. The grooves can match the main axis.
[0009] As a first further improved technical solution of the present utility model, the purlin includes a first pressing tongue plate located above one of the grooves and a second pressing tongue plate located above the other groove. The first pressing tongue plate and the second pressing tongue plate are formed during the stamping process of the groove and extend in the opposite direction.
[0010] As a first further improved technical solution of the present utility model, the top plate includes a first inclined surface and a second inclined surface that extend with a smooth transition. The first inclined surface is connected between the first plane and the third plane, and the second inclined surface is connected between the second plane and the third plane.
[0011] As a first further improved technical solution of the present utility model, the third connecting member is one of a bolt and a hoop; the purlin is a symmetric structure in the left - right direction and the front - back direction.
[0012] To achieve the above object, the present utility model adopts the following technical solution two: A photovoltaic support, including the photovoltaic connection assembly and the main shaft as described above.

[0013] As the second technical solution for further improvement of the present utility model, it further includes a cable, and the cable is laid above the main shaft and passes through between the purlin of the photovoltaic connection component and the photovoltaic module.
[0014] Compared with the prior art, in the photovoltaic connection component and the purlin of the photovoltaic support of the present utility model, it includes a top plate and a bending plate formed by stamping downward from the top plate. There are two bending plates, which are respectively located on the front and rear sides of the top plate. When looking from one end of the purlin to the other end along the left-right direction, an opening is formed between the two bending plates and the top plate. The opening faces away from the first connecting piece and faces the third connecting piece. That is, in the photovoltaic support, the opening faces away from the photovoltaic module and faces the main shaft for installation. Therefore, the present utility model can make the cavity of the photovoltaic module fixed on the main shaft through the photovoltaic connection component completely located on the installation surface of the top plate of the purlin, so that the load-bearing capacity that can be withstood in case of damage becomes larger. At the same time, the supporting force provided by the purlin is more stable, the purlin can withstand greater wind pressure, and the risk of bending deformation is reduced.

[0036] Please refer to Figures 1 to 18 As shown, the present utility model discloses a photovoltaic connection assembly 100 for fixedly installing a photovoltaic module 200 on the main shaft 300 of a photovoltaic support. The extending direction of the main shaft 300 is defined as the front-rear direction, and the cross-section of the main shaft 300 further has an up-down direction and a left-right direction, and the up-down direction, the left-right direction and the front-rear direction are perpendicular to each other in pairs. The present utility model also discloses a photovoltaic support which, in addition to including the photovoltaic connection assembly 100 described above, further includes the main shaft 300.
[0037] Please refer to Figures 1 to 16 As shown, in the specific embodiment, the photovoltaic connection assembly 100 includes a first connector 1 located above for fixing to the photovoltaic module 200, a purlin 2 located in the middle and serving as a second connector, and a third connector 3 located below for fixing to the main shaft 300. In other embodiments, the purlin 2 can be directly used to connect to the photovoltaic module 200, or can be fixed by directly bolting the purlin 2 and the bottom of the frame of the photovoltaic module 200. In this case, the width of the purlin 2 needs to be increased. Therefore, the photovoltaic connection assembly 100 in other embodiments includes a purlin 2 for connecting to the photovoltaic module 200 and a third connector 3 for fixing to the main shaft 300, that is, the first connector 1 in the specific embodiment is a non-essential element.
[0038] Please refer to Figure 15 and Figure 16, the purlin 2 includes a top plate 21 and a bent plate 22 extending downward from the top plate 21. There are two bent plates 22, which are respectively located on the front and rear sides of the top plate 21. When looking from one end of the purlin 2 to the other end along the left-right direction, an opening 20 is formed between the two bent plates 22 and the top plate 21. The opening 20 faces away from the top plate 21 and faces the third connecting member 3. That is, in the photovoltaic support, the opening 20 faces away from the photovoltaic module 200 and faces the installation of the main shaft 300. The photovoltaic module 200 fixed on the main shaft 300 by the photovoltaic connection assembly 100 of the present invention has its frame cavity completely located on the installation surface where the top plate 21 of the purlin 2 is located, so that the load-bearing capacity that can be withstood in case of damage becomes larger. At the same time, the supporting force provided by the purlin 2 is more stable, the purlin 2 can withstand a large wind pressure, and the risk of bending deformation is reduced.
[0039] Please refer to Figures 8 to 16 As shown, the top plate 21 includes an end plane 211. The end plane 211 includes a first plane 2111 at the left end and a second plane 2112 at the right end. The first plane 2111 and the second plane 2112 are coplanar and are used to support the photovoltaic module 200. In a specific embodiment of the present invention, the first plane 2111 and the second plane 2112 are used to cooperate with the first connecting member 1 above to fix the photovoltaic module 200 above the photovoltaic connection assembly 100 of the present invention. Therefore, the end plane 211 is the installation surface where the top plate 21 is located. It can be seen that the end plane 211 is a whole plane without other gaps except the installation hole (the second hole 2110 described below). After installation, the cavity part of the photovoltaic module 300 will not be suspended, and a better and stronger supporting force can be provided for the photovoltaic module 300.
[0040] Please refer to Figures 10 to 13 As shown, in a specific embodiment, the first connecting member 1 is located above the purlin 2 and is used to fix the photovoltaic module 200. Therefore, the purlin 2 is located between the first connecting member 1 and the third connecting member 3. The first connecting member 1 includes a pressing block 11 and a fastener 12. One end of the pressing block 11 is provided with a first hole 110, and the end plane 211 is provided with a second hole 2110. The fastener 12 passes through the first hole 110 and the second hole 2110. The other end of the pressing block 11 is pressed above the frame of the photovoltaic module 200, that is, above the module frame. Through the cooperation of the pressing block 11 and the fastener 12, the module frame is positioned and connected to the purlin 2. Therefore, the photovoltaic module 200 is also positioned and connected to the purlin 2. In other embodiments, the first connecting member only includes the fastener 12 and does not include the pressing block 11. For other embodiments of the first connecting member 1, please refer to Figures 4 to 6 ,Figure 17 and Figure 18 A third hole 201 is provided on the component frame, and the fastener passes through the third hole 201 and the second hole 2110 on the end plane 211. Therefore, only through the fastener 12, the component frame can be positioned and connected to the purlin 2.
[0041] Please refer to Figures 14 to 16 As shown, the top plate 21 includes a third plane 2113 located in the middle and parallel to the first plane 2111 and the second plane 2112, and the third connecting member 3 is positioned and connected to the third plane 2113. The third plane 2113 itself is a planar structure, and the bottom shape of the bending plate 22 below the third plane 2113 can match the contour shape of the main shaft 300 (to be described in detail later). In the present invention, the third plane 2113 is used to cooperate with the third connecting member 3 below to fix the main shaft 300 below the photovoltaic connection component 100 of the present invention.
[0042] Please refer to Figure 14 As shown, in terms of the up and down direction, the height value of the third plane 2113 relative to the main shaft 300 is lower than the height values of the first plane 2111 and the second plane 2112 relative to the main shaft 300. The structural design with both ends high and the middle low increases the distance between the photovoltaic module 200 and the main shaft 300, providing a layout space for other components (such as the cable 500); in other embodiments, the height of the third plane 2113 can be the same as the height of the left and right ends of the purlin 2, that is, the height of the first plane 2111 and the second plane 2112.
[0043] Please refer to Figure 15 As shown, in terms of the front and back direction, the width value of the third plane 2113 is smaller than the width values of the first plane 2111 and the second plane 2112, that is, in the specific embodiment, the width of the third plane 2113 is smaller than the end width. Such a setting makes the overall width of the purlin 2 not exceed the width values of the left and right ends of the purlin 2, that is, the first plane 2111 and the second plane 2112, even if the first tongue plate 2115 and the second tongue plate 2116 are formed by stamping, which is beneficial to saving space and making the product structure of the purlin 2 compact; in other embodiments, the width of the third plane 2113 can be the same as the width of the left and right ends of the purlin 2, that is, the first plane 2111 and the second plane 2112.
[0044] Please refer to Figure 14 、 Figure 15 and Figure 16As shown, the bent plate 22 is formed by stamping downward from the top plate 21. At the position corresponding to the third plane 2113 of the bent plate 22, there are two grooves 2114 formed by stamping upward from the bottom and arranged front and back correspondingly. The grooves 2114 can be matched with the main shaft 300. With such a setting, the purlin 2 can be perfectly matched with the main shaft 300. During the rotation of the main shaft 300, the purlin 2 can better follow the rotation of the main shaft 300.
[0045] Please continue to refer to Figure 14 、 Figure 15 and Figure 16 As shown, the purlin 2 includes a first tongue plate 2115 above one of the grooves 2114 and a second tongue plate 2116 above the other groove 2114. The first tongue plate 2115 and the second tongue plate 2116 are formed during the stamping process of the groove 2114 and extend in opposite directions. With such a setting, it is used to increase the contact area between the purlin 2 and the main shaft 300, so that the connection between the purlin 2 and the main shaft 300 is more stable; the purlin structure of the present application directly fixedly connects the purlin 2 and the main shaft 300 through the third connecting member 3, cancels the purlin mounting seat in the prior art, saves production costs and also reduces the installation process, thereby reducing labor and installation costs.
[0046] Please refer to Figure 15 As shown, the top plate 21 includes a first inclined surface 2117 and a second inclined surface 2118 that extend with a smooth transition. The first inclined surface 2117 is connected between the first plane 2111 and the third plane 2113, and the second inclined surface 2118 is connected between the second plane 2112 and the third plane 2113. The setting of the two inclined surfaces 2117 and 2118 is also to achieve the structural design with high ends and low middle, increase the distance between the photovoltaic module 200 and the main shaft 300, and provide a layout space for other components (such as the cable 500).
[0047] Please refer to Figures 10 to 14 As shown, the third connecting member 3 is one of a bolt and a hoop. The hoop is an integral hoop or a split hoop; the bolt is an integral U-shaped bolt (not shown) or a split through bolt 31. In the specific implementation manner, the third connecting member 3 is the through bolt 31, and there are two through bolts 31; however, the split through bolt 31 also needs to be used in cooperation with the lower pressing plate 32. The through bolt 31 is connected between the top plate 21 of the purlin 2 and the lower pressing plate 32 to form the receiving space 30 of the main shaft 300. For more structural designs of the third connecting member 3, the present invention will not be elaborated further.
[0048] Please refer to Figures 1 to 16As shown, the purlin 2 is a symmetric structure in the left-right direction and the front-back direction, ensuring the stability of the structure.
[0049] The present utility model also discloses a photovoltaic support. Please refer to Figures 1 to 18 and with particular reference to Figure 1 and Figure 2 , which includes the photovoltaic connection component 100 and the main shaft 300 as described above. The photovoltaic connection component 100 is used to connect the photovoltaic module 200 to the main shaft 300. Further, please refer to Figure 2 . The photovoltaic support of the present utility model further includes a cable 500 for transmitting electrical signals. The cable 500 is laid above the main shaft 300 and passes between the purlin 2 of the photovoltaic connection component 100 and the photovoltaic module 200.
[0050] In the photovoltaic connection component 100 of the photovoltaic support of the present utility model, the end of the second connecting member, that is, the purlin 2, is a planar structure, which is used to support the photovoltaic module 200. The component frame is completely arranged on the end plane 211. Compared with the U-shaped purlin, the stress concentration is reduced, the provided supporting force is more stable, the wind pressure resistance ability of the photovoltaic module 200 is improved, the tearing of the component frame under the action of strong wind is avoided, and the risk of bending deformation is reduced; at the same time, the photovoltaic connection component 100 can be pre-installed in the factory. After arriving at the project site, after passing through the main shaft 300 or pressing into the photovoltaic module 200, the corresponding third connecting member 3 or the first connecting member 1 can be tightened, reducing the installation process at the project site and saving labor costs.
[0051] The above embodiments are only used to illustrate the present utility model and do not limit the technical solutions described in the present utility model. The understanding of the present utility model should be based on those skilled in the art of the relevant technical field. Although this specification has described the present utility model in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the relevant technical field can still modify or equivalently replace the present utility model. All technical solutions and their improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
