[0027] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings. It is hereby declared that the upper, lower, left, right, front, rear, inner, outer, etc. orientation terms that appear or will appear in the text of the present utility model are only based on the drawings of the present utility model and do not specifically limit the present utility model.

[0028] The photovoltaic panel connector 1 of the present utility model enables the entire connection process between the photovoltaic panel 3 and the guide rail 2 to be located below the photovoltaic panel 3, and the connection structure between the guide rail 2 and the photovoltaic panel 3 is simple, effectively reducing the time of high-altitude operations during the construction process and thus reducing the prone safety problems.

[0029] In a specific embodiment of the present utility model, the photovoltaic panel connector 1 is used to connect the photovoltaic panel 3 and the guide rail 2. As Figures 1 to 3As shown in the figure, the photovoltaic panel connector 1 includes a support plate 11 and two connecting plates 12. The support plate 11 is located between the two connecting plates 12, and the support plate 11 and the two connecting plates 12 are integrally formed. The support plate 11 and the two connecting plates 12 enclose to form an installation groove 13. The guide rail 2 is installed in the installation groove 13, and the distance between the top of the connecting plate 12 and the support plate 11 is greater than or equal to the thickness of the guide rail 2, and the distance between the two connecting plates 12 is greater than or equal to the width of the guide rail 2. The connecting plate 12 is formed with a first flanging 121, and the connecting plate 12 is connected to the lower side of the photovoltaic panel 3 through the first flanging 121.

[0030] For the photovoltaic panel connector 1 provided in this embodiment, since the distance between the top of the connecting plate 12 and the support plate 11 is greater than or equal to the thickness of the guide rail 2, and the distance between the two connecting plates 12 is greater than or equal to the width of the guide rail 2, that is, the size of the installation groove 13 is greater than or equal to the size of the guide rail 2. Further, when installing the guide rail 2 on the photovoltaic panel connector 1, the installation groove 13 can completely accommodate the guide rail 2, so as to simplify the installation process of the guide rail 2 without other complex adjustments. Subsequently, the connecting plate 12 and the lower side of the photovoltaic panel 3 are connected by using the first flanging 121, and the connection between the guide rail 2 and the photovoltaic panel 3 can be completed.

[0031] Since the installation process of the guide rail 2 in the installation groove 13 and the connection process between the connecting plate 12 and the photovoltaic panel 3 are all carried out below the photovoltaic panel 3, and there is no need to use other components such as pressing blocks to fix the upper part of the photovoltaic panel 3, the entire connection process between the photovoltaic panel 3 and the guide rail 2 is located below the photovoltaic panel 3, and the connection structure between the guide rail 2 and the photovoltaic panel 3 is simple, thus effectively reducing the time of high-altitude operation during the construction process and further reducing the safety problems that are likely to occur.

[0032] It should be noted here that since the installation groove 13 can completely accommodate the guide rail 2, it can ensure that the guide rail 2 can be accurately fixed during the installation process, reduce the installation error, and avoid the influence of external changes on the guide rail 2, thereby improving the connection accuracy between the guide rail 2 and the photovoltaic panel 3.

[0033] Among them, as Figure 1 and Figure 2 shown, a first installation portion 111 is formed inside the installation groove 13, and the guide rail 2 is detachably connected to the installation groove 13 through the first installation portion 111, so as to improve the operation convenience when the guide rail 2 is installed on the photovoltaic panel connector 1, and facilitate the maintenance or replacement of the guide rail 2.

[0034] Specifically, a through hole is formed on the side of the guide rail 2 facing the support plate 11. In order to detachably connect the guide rail 2 and the installation groove 13, the connection method between the guide rail 2 and the support plate 11 can adopt the following connection methods for example:

[0035] For the first connection method, the first mounting portion 111 is a threaded hole formed in the support plate 11, and the guide rail 2 and the support plate 11 are connected by screw threads of a bolt. Specifically, when connecting the guide rail 2 and the support plate 11, align the through hole of the guide rail 2 with the threaded hole of the support plate 11. Subsequently, pass the bolt through the through hole and the threaded hole, and then tighten the nut at the lower end of the bolt so that the guide rail 2 and the support plate 11 are connected by screw threads. The overall installation process of the guide rail 2 and the support plate 11 can be completed before being connected to the photovoltaic panel 3, without the need for high-altitude operations, thereby reducing safety issues during the construction process.

[0036] For the second connection method, the first mounting portion 111 is a buckle, and the buckle is snapped into the through hole, and the guide rail 2 and the support plate 11 are connected by snapping. Specifically, when connecting the guide rail 2 and the support plate 11, align the through hole of the guide rail 2 with the buckle of the support plate 11, and insert the buckle into the through hole to snap-connect the guide rail 2 and the support plate 11. The entire connection process also does not require high-altitude operations and can also reduce safety issues during the construction process.

[0037] In this embodiment, the first connection method is preferably adopted between the guide rail 2 and the support plate 11.

[0038] The present utility model also provides a photovoltaic support, as Figures 1 to 4 shown. The photovoltaic support includes a concrete base 4, a column 5, a main beam 6, a guide rail 2, a photovoltaic panel 3, and the photovoltaic panel connector 1 described in any one of the above embodiments. The first end of the column 5 is fixed to the concrete base 4, and the main beam 6 is installed at the second end of the column 5. The photovoltaic panel connector 1 is detachably connected to the main beam 6. Specifically, when the guide rail 2 and the support plate 11 are connected by screw threads of a bolt, the bolt passes through the main beam 6 and is fixed by tightening the nut, so that while the photovoltaic panel connector 1 and the main beam 6 are connected by screw threads, the connection components between the main beam 6 and the photovoltaic panel connector 1 are reduced.

[0039] The guide rail 2 is installed in the installation groove 13, and a second flanging 31 is provided on the lower side of the photovoltaic panel 3, and the second flanging 31 is detachably connected to the first flanging 121.

[0040] It can be understood that by detachably connecting the first flanging 121 of the photovoltaic panel connector 1 to the second flanging 31 on the lower side of the photovoltaic panel 3, it can be ensured that the connection structure between the guide rail 2 and the photovoltaic panel 3 is located below the photovoltaic panel 3. Since the installation of the concrete base 4, the column 5, and the main beam 6 are all located below the photovoltaic panel 3, the entire installation process of the photovoltaic support is completely located below the photovoltaic panel 3, further ensuring that the construction process of the photovoltaic support only needs to be operated below the photovoltaic panel 3, thereby reducing high-altitude operations during the construction process and ensuring the safety of construction workers.

[0041] It should be noted here that the column 5 and the concrete base 4 can be connected by bolts, and the column 5 and the main beam 6 can be connected by bolts. The connection structure between the column 5 and the concrete base 4, as well as the specific connection structure between the main beam 6 and the column 5, are existing structures and will not be elaborated here.

[0042] Specifically, as Figure 2 shown, the first flanging 121 is formed with a first mounting hole 122, and the second flanging 31 is formed with a second mounting hole. When the first flanging 121 is connected to the second flanging 31, the first mounting hole 122 and the second mounting hole are coaxial. The first flanging 121 and the second flanging 31 are provided with connecting bolts, and the connecting bolts are inserted through the first mounting hole 122 and the second mounting hole. Further, when connecting the photovoltaic panel 3 and the photovoltaic panel connector 1, the connecting bolts can be inserted through the coaxial first mounting hole 122 and the second mounting hole to thread-connect the first flanging 121 and the second flanging 31, so as to improve the convenience when connecting the photovoltaic panel 3 and the photovoltaic panel connector 1.

[0043] Furthermore, to improve the connection efficiency between the photovoltaic panel 3 and the photovoltaic panel connector 1, as Figure 2 shown, one of the first flanging 121 and the second flanging 31 is formed with a positioning protrusion 123, and the other of the first flanging 121 and the second flanging 31 is formed with a positioning hole, and the positioning protrusion 123 is adapted to be inserted into the positioning hole. Specifically, the positioning protrusion 123 is formed on the first flanging 121, and the positioning hole is formed on the second flanging 31.

[0044] Furthermore, during the process of connecting the photovoltaic panel connector 1 to the photovoltaic panel 3, the positioning protrusion 123 can be first inserted into the positioning hole, and the positioning of the photovoltaic panel connector 1 on the photovoltaic panel 3 can be completed by using the positioning protrusion 123 and the positioning hole, so that the first flanging 121 and the second flanging 31 can be connected by connecting bolts, thereby improving the connection efficiency between the photovoltaic panel 3 and the photovoltaic panel connector 1.

[0045] In this embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the photovoltaic support further includes a support plate 7. The support plate 7 is arranged at the upper end of the photovoltaic panel connector 1, and both ends of the support plate 7 are clamped between the first flanging 121 and the second flanging 31, and the middle part of the support plate 7 is located above the installation groove 13. Both ends of the support plate 7 are provided with third mounting holes 71, and the third mounting holes 71 are coaxial with the first mounting hole 122 and the second mounting hole.

[0046] It can be understood that by installing the supporting plate 7 between the first flanging 121 and the second flanging 31, the thickness of the connection position between the photovoltaic panel 3 and the photovoltaic panel connector 1 is increased, enabling the photovoltaic panel connector 1 and the guide rail 2 to effectively support the weight of the photovoltaic panel 3; and the supporting plate 7 is used to disperse the pressure of the photovoltaic panel 3 on the photovoltaic panel connector 1, preventing the photovoltaic panel connector 1 from being bent or damaged due to excessive local stress, which affects the supporting effect of the photovoltaic panel connector 1 on the photovoltaic panel 3, thereby extending the service life of the photovoltaic panel connector 1.

[0047] Moreover, since the middle part of the supporting plate 7 is located above the installation groove 13, that is, the supporting plate can enclose the installation groove, so that the part where the guide rail 2 is connected to the photovoltaic panel connector 1 is completely wrapped by the supporting plate 11, the supporting plate 7 and the two connecting plates 12, further ensuring the installation stability of the guide rail 4.

[0048] It should be noted here that the length L1 of the supporting plate 7 is equal to the distance L2 between the two flangings of the photovoltaic panel connector 1 to ensure accurate alignment between the photovoltaic panel connector 1 and the supporting plate 7 and reduce the installation error.

[0049] It should also be noted here that when installing the supporting plate 7, the supporting plate 7 can be placed between the first flanging 121 and the second flanging 31, and the connecting bolt is passed through the first mounting hole 122, the third mounting hole 71 and the second mounting hole to install and fix the supporting plate 7 between the first flanging 121 and the second flanging 31 by using the connecting bolt and the nut.

[0050] Furthermore, to improve the connection efficiency between the supporting plate 7 and the photovoltaic panel 3, as Figure 3 shown, third flangings 72 are provided at both ends of the supporting plate 7. The third flangings 72 are perpendicular to the supporting plate 7, and the end of the second flanging 31 abuts against the third flanging 72. Then when connecting the photovoltaic panel 3 and the supporting plate 7, the second flanging 31 of the photovoltaic panel 3 can be placed in the supporting plate 7 along the third flanging 72 of the supporting plate 7, and the third flanging 72 is used to limit the photovoltaic panel 3, so as to connect the supporting plate 7 and the photovoltaic panel 3 through the connecting bolt, thereby improving the connection efficiency between the supporting plate 7 and the photovoltaic panel 3.

[0051] In another embodiment, as Figure 3As shown, a third flanging 72 forms a limiting boss 73. The limiting boss 73 faces the second flanging 31. The distance between the bottom of the limiting boss 73 and the support plate 7 is D1, and the end thickness of the second flanging 31 is D2, and D1 is equal to D2. It can be understood that in this embodiment, since there is a certain distance D1 between the bottom of the limiting boss 73 and the support plate 7, that is, a groove-like structure is formed between the limiting boss 73 and the support plate 7; and since the thickness D2 of the second flanging 31 of the photovoltaic panel 3 is equal to the thickness D1 of the groove-like structure, the second flanging 31 of the photovoltaic panel 3 matches the thickness of the groove-like structure, and the second flanging 31 of the photovoltaic panel 3 can be inserted into the groove-like structure. When it is necessary to connect the photovoltaic panel 3 and the support plate 7, the second flanging 31 of the photovoltaic panel 3 can be inserted into the groove-like structure between the limiting boss 73 and the support plate 7 to limit the second flanging 31 of the photovoltaic panel 3 by using the limiting boss 73, further enhancing the connection stability between the photovoltaic panel 3 and the support plate 7.

[0052] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
