[0026] like Figure 1 and Figure 2 As shown, the present invention provides a support structure for a photovoltaic module, comprising a first photovoltaic panel body 10, a second photovoltaic panel body 20, a pressing assembly and a bottom plate 60, wherein the pressing assembly is inserted between the first photovoltaic panel body 10 and the second photovoltaic panel body 20;

[0027] The clamping assembly includes a clamping block 30 and a rod body 40. The rod body 40 is arranged on the end surface of the clamping block 30 facing the base plate 60, and the rod body 40 is inserted between the first photovoltaic panel body 10 and the second photovoltaic panel body 20, and drives the clamping block 30 to apply clamping force to the first photovoltaic panel body 10 and the second photovoltaic panel body 20 respectively.

[0028] The clamping assembly is inserted between the first photovoltaic panel body 10 and the second photovoltaic panel body 20, wherein the clamping assembly includes a clamping block 30 and a rod body 40, and the rod body 40 is arranged on the end face of the clamping block 30 facing the base plate 60. During installation, the staff inserts the rod body 40 between the first photovoltaic panel body 10 and the second photovoltaic panel body 20, and drives the clamping block 30 through the rod body 40 to apply a clamping force to the first photovoltaic panel and the second photovoltaic panel, so that the first photovoltaic panel body 10 and the second photovoltaic panel body 20 can be firmly connected to the base plate 60, which alleviates the technical problem in the prior art that in the horizontal double-row arrangement structure, the traditional photovoltaic bracket purlin structure cannot fix the long side of the photovoltaic module well. If only the short side is fixed, it will lead to a loose installation, and there is a hidden danger of the photovoltaic module falling off, thereby improving the installation quality of the photovoltaic module.

[0029] It should be noted that the present application can also set up multiple base plates 60, and multiple photovoltaic panels adopt the structure of the above-mentioned first photovoltaic panel 10 and second photovoltaic panel 20 and are distributed side by side on multiple base plates 60 to achieve a double-row arrangement of photovoltaic panels. At the same time, the first photovoltaic panel 10 and the second photovoltaic panel 20 can also be compressed along the long side using multiple relatively arranged clamping components to further enhance the connection strength of the photovoltaic panel relative to the base plate 60, thereby improving the overall installation quality of the photovoltaic assembly.

[0030] Furthermore, according to the actual installation structure of the photovoltaic panel, the clamping assembly can also be installed between multiple photovoltaic panels such as the first photovoltaic panel 10, the second photovoltaic panel 20, and the third photovoltaic panel, wherein the first photovoltaic panel 10, the second photovoltaic panel 20 and the third photovoltaic panel are distributed in a star shape. Since the present application uses a mode in which the rod 40 drives the pressure block 30 for clamping, it is suitable for a variety of distribution forms of photovoltaic panels, thereby improving the applicable scenarios of this embodiment.

[0031] Furthermore, the pressing block 30 includes a contact portion 31 and a connecting portion 32 , and the cross-sectional area of ​​the connecting portion 32 is adapted to the gap between the first photovoltaic panel body 10 and the second photovoltaic panel body 20 ;

[0032] The contact portion 31 and the connecting portion 32 are arranged in a T-shape, and the cross-sectional area of ​​the contact portion 31 is larger than the cross-sectional area of ​​the connecting portion 31;

[0033] The contact portion 31 contacts the upper surface of the first photovoltaic panel 10 and the upper surface of the second photovoltaic panel 20 , respectively.

[0034] The pressing block 30 includes a contact portion 31 and a connecting portion 32, and the contact portion 31 and the connecting portion 32 are arranged in a T shape, wherein the connecting portion 32 is adapted to the gap between the first photovoltaic panel body 10 and the second photovoltaic panel body 20, and in the process of the rod body 40 being inserted into the gap between the first photovoltaic panel body 10 and the second photovoltaic panel body 20, the connecting portion 32 contacts the side walls of the first photovoltaic panel body 10 and the second photovoltaic panel body 20, and plays a supporting role between the first photovoltaic panel body 10 and the second photovoltaic panel body 20, so as to facilitate the control of the gap distance between the first photovoltaic panel body 10 and the second photovoltaic panel body 20. At the same time, the cross-sectional area of ​​the contact portion 31 is larger than the cross-sectional area of ​​the contact portion 31, so that the contact portion 31 can contact the upper surface of the first photovoltaic panel body 10 and the upper surface of the second photovoltaic panel body 20 respectively, and under the drive of the rod body 40, the contact portion 31 applies a pressing force to the first photovoltaic panel body 10 and the second photovoltaic panel body 20 respectively.

[0035] Furthermore, the clamping assembly also includes a nut 50 , the end of the rod 40 away from the pressing block 30 passes through and extends out of the base plate 60 , and the end of the rod 40 away from the pressing block 30 is provided with an external thread 41 , and the nut 50 is bolted to the external thread 41 .

[0036] The end of the rod body 40 facing away from the pressing block 30 passes through and extends out of the base plate 60. Through the cooperation of the nut 50 and the external thread 41, the nut 50 applies a reaction force on the base plate 60 that is opposite to the insertion direction of the rod body 40, thereby fixing the insertion length of the rod body 40. At the same time, the pressing force of the pressing block 30 on the first photovoltaic panel body 10 and the second photovoltaic panel body 20 can also be controlled through the rod body 40; that is, the first photovoltaic panel body 10 and the second photovoltaic panel body 20 can be fixed relative to the base plate 60 only by the restraint between the nut 50 and the external thread 41, thereby reducing labor intensity and improving installation efficiency.

[0037] It should be noted that the end of the rod body 40 extending out of the base plate 60 can also be fixed by, but is not limited to, a clamp, a connecting piece connected to the rod body 40, etc. In comparison, the method of fixing with a nut 50 is simpler, more convenient for on-site construction, and low in cost.

[0038] Furthermore, a gasket 70 is provided between the nut 50 and the base plate 60 .

[0039] The setting of the gasket 70 can prevent the bottom of the base plate 60 from being scratched when the nut 50 and the rod body 40 are threaded too close. At the same time, the gasket 70 includes a steel gasket 70 and a spring gasket 70. The spring gasket 70 is set between the steel gasket 70 and the nut 50, and through its own elastic force, it increases the clamping force of the nut 50 on the steel gasket 70.

[0040] Furthermore, the pressing block 30 is provided with a connecting hole, and the end of the rod body 40 facing the pressing block 30 is detachably connected to the connecting hole.

[0041] In this embodiment, the pressing block 30 is provided with a connecting hole, and the end of the rod body 40 facing the pressing block 30 can be detachably connected to the connecting hole, which is convenient for on-site processing or replacement of the rod body 40 with different lengths according to different usage scenarios.

[0042] It should be noted that the pressing block 30 and the rod body 40 can also be provided in an integrally connected manner for ease of processing.

[0043] Furthermore, the connecting portion 32 is a square structure.

[0044] Since most photovoltaic panels currently have a square structure, the connecting portion 32 in the pressing block 30 is configured as a square structure to adapt to the shape of the photovoltaic panel.

[0045] It should be noted that the shape of the connecting portion 32 is set according to the specific structure of the photovoltaic panel.

[0046] Furthermore, the end surface of the contact portion 31 facing away from the rod body 40 is a curved surface.

[0047] The curved surface setting can make the surface smoother, avoiding scratches and the like during the installation process. At the same time, the curved surface setting can also improve the aesthetics of the product.

[0048] Furthermore, the bottom plate 60 is a U-shaped carbon steel purlin.

[0049] The opening of the U-shaped steel purlin is perpendicular to the photovoltaic panel, and the flanges on both sides of the U-shaped steel purlin are placed at the lower part of the photovoltaic component frame. The arrangement of the flanges on both sides can be connected to the side edges of the first photovoltaic panel and the second photovoltaic panel respectively.

[0050] Furthermore, a frame is provided on the side of the first photovoltaic panel 10 and the second photovoltaic panel 20 facing the bottom plate 60 , and the frame is used to support the first photovoltaic panel 10 or the second photovoltaic panel 20 .

[0051] The frame not only supports the first photovoltaic panel 10 or the second photovoltaic panel 20, but also protects the first photovoltaic panel 10 and the second photovoltaic panel 20, facilitates installation and transportation, and increases the sealing and overall mechanical strength of the crystalline silicon photovoltaic module.

[0052] Furthermore, the bottom plate 60 is provided with a through hole adapted to the rod body 40 , and the rod body 40 is inserted into the through hole.

[0053] A through hole that is compatible with the rod body 40 is set in the base plate 60, so that the rod body 40 can easily pass through the base plate 60. At the same time, the setting of the through hole also plays a limiting role. The on-site installers can determine the arrangement of the first photovoltaic panel body 10 and the second photovoltaic panel body 20 according to the specific distribution of the through hole.

[0054] Furthermore, the outer surfaces of the above-mentioned structures such as the pressing block 30, the rod body 40, and the bottom plate 60 are all galvanized to improve the service life of the product.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
