If a waterproof solution is used, the gap is large and sealed with a rubber strip, which will still cause dripping and cannot meet the seamless waterproof requirements of the module. In addition, the pressing blocks on the market are basically fastened with bolts, and the bolts need to be tightened from the bottom of the module, which is complicated to install. Referring to the Chinese utility model patent with the authorization announcement number CN 219697533 U, a photovoltaic module connection device is disclosed, including two relatively arranged frames, a gap between the inner sides of the two frames, and a waterproof plugging strip embedded in the upper end opening of the gap, and also including a pair of mounting parts, the outer end of the mounting part is provided with a positioning groove opening inward, the inner end of the mounting part is provided with a positioning hole, the outer end of the pressing plate is inserted into the positioning groove, the positioning holes of the two mounting parts in the same group overlap, and a fastener is provided in the gap, the upper end of the fastener is connected to the waterproof plugging strip, and the lower end of the fastener passes through the two positioning holes in the same group and connects to the crossbeam. Therefore, if the seamless installation of the photovoltaic module is achieved and bolt fasteners are not required, the leakage problem can be reduced and the installation operation is convenient. [Contents of the utility model]

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a photovoltaic component fixing structure with seamless installation, reduce water leakage problems, and facilitate installation operations.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A seamlessly installed photovoltaic component fixing structure includes a crossbeam and a photovoltaic component installed on the crossbeam, the photovoltaic component having a frame, the bottom of the frame having a bottom plate extending inward, the frames of two laterally adjacent photovoltaic components being arranged in a close fit, the photovoltaic component fixing structure also including a waterproof buckle, the upper portion of the waterproof buckle is provided with a laterally opening slot, the bottom plate is engaged in the slot, the lower portion of the waterproof buckle is provided with a lower fixing buckle, the crossbeam is provided with a fixing portion, and the lower fixing buckle is fixed to the fixing portion.

[0006] Preferably, the clamping slot is provided with a lower clamping edge and an upper clamping edge, the lower clamping edge is supported on the bottom surface of the bottom plate, and the upper clamping edge is pressed on the top surface of the bottom plate.

[0007] Preferably, the upper clamping edge is provided with a pressing portion pressed on the top surface of the bottom plate and a bending portion connecting the pressing portion and the lower clamping edge, and the bending portion enables the pressing portion to generate a clamping force to cooperate with the lower clamping edge to clamp the bottom plate.

[0008] Preferably, the pressing portion is provided with a pressing protrusion.

[0009] Preferably, the longitudinal width of the pressing portion is greater than the longitudinal width of the crossbeam.

[0010] Preferably, the crossbeam is C-shaped steel or U-shaped steel.

[0011] Preferably, the fixing portion is an inner fixed rib provided on the inner side of the C-shaped steel or U-shaped steel mouth, and the lower fixing buckle includes side spring sheets provided on both sides of the waterproof buckle, and the upper ends of the side spring sheets are fixedly matched with the inner fixed rib.

[0012] Preferably, the inner fixed retaining edge is folded inwardly to form a limiting groove, and the side spring piece extends obliquely upward and is provided with a limiting edge at the upper end to be engaged with the limiting groove.

[0013] Preferably, a fixing block inserted into the inner side of the cross beam is provided at the lower part of the waterproof buckle, and the lower fixing end of the side spring piece is connected to the bottom side of the fixing block.

[0014] Preferably, the waterproof buckle is a profile with an integrated structure.

[0015] The utility model adopts the above technical solution and has the following beneficial effects:

[0016] 1. The frames of two adjacent photovoltaic modules are fitted together to prevent water leakage without any gaps. No waterproof strips are required, which solves the need for seamless installation of photovoltaic systems on flat roofs, especially sloping roofs, and reduces water leakage.

[0017] The photovoltaic module is fixed to the crossbeam by a waterproof buckle, wherein the slot provided on the upper part of the waterproof buckle clamps and fixes the bottom plate, and the lower fixing buckle provided on the lower part of the waterproof buckle is fixed to the fixing part on the crossbeam. During installation, the waterproof buckle clamps the bottom plate of the bottom frame of the photovoltaic module through the slot and fixes it as a whole with the photovoltaic module, and then the photovoltaic module is installed on the crossbeam, and the lower fixing buckle is fastened with the fixing part on the crossbeam. Compared with the existing waterproof pressure block fastened by bolts, it is simple and easy to operate, and the installation efficiency is improved; since no bolts are required and the amount of pressure blocks used is small, the cost can be reduced.

[0018] 2. The lower clamping edge of the clamping slot is supported on the bottom surface of the bottom plate, and the upper clamping edge is pressed on the top surface of the bottom plate to clamp the bottom plate. The upper clamping edge is provided with a bending portion, and the bending portion enables the pressing portion to generate a clamping force that cooperates with the lower clamping edge to clamp the bottom plate, thereby ensuring reliable clamping of the bottom plate.

[0019] 3. Since the longitudinal width of the pressing part is greater than the longitudinal width of the beam, it has a larger effective area with the bottom plate, and the pressing protrusion can increase the friction between the bottom plate edge, further improving the pressing stability, avoiding looseness, and ensuring that the bottom plate is clamped.

[0020] 4. The crossbeam is C-shaped steel or U-shaped steel, and an inner fixed rib is arranged on the inner side of the mouth, and side spring plates are arranged on both sides of the lower fixing buckle. When installing, the lower fixing buckle is pressed downward into the inner side of the crossbeam. The side spring plates shrink and deform during the pressing process. After being pressed into the crossbeam, they expand outward. Finally, the upper end of the side spring plates cooperates with the inner fixed rib to achieve snap-fit ​​fixation. No tools are required during the installation process, which facilitates quick installation.

[0021] 5. As the inner fixed retaining edge is folded inward to form a limiting groove, the side spring piece pressed into the inner side of the beam expands outward, and the limiting edge at its upper end is inserted into the limiting groove to form a limiting fit, thereby preventing the lower fixing buckle from separating upward from the beam.

[0022] 6. A fixing block that can slide along the inner side of the beam is provided at the bottom of the waterproof buckle. After the fixing block is inserted into the inner side of the beam from top to bottom, the side spring piece returns to its original state, and the limiting edge is inserted into the limiting groove to fix the upper and lower positions of the entire waterproof buckle.

[0023] 7. Since the waterproof buckle is an integrated structural profile, such as an aluminum alloy profile, it can be extruded to achieve industrial production, significantly reduce costs, and has high strength and long service life.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[Specific implementation method]

[0032] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0033] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0034] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the following words indicating orientation or positional relationship, such as "upper", "lower", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0035] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0036] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0037] Reference Figures 1 to 5As shown, a photovoltaic component fixing structure for seamless installation, taking the photovoltaic system installed on the existing sloping roof as an example, includes a plurality of beams 3 arranged side by side in the longitudinal direction and photovoltaic components 2 fixed on the beams 3, wherein the photovoltaic components 2 have a frame 21, and the bottom of the frame has a bottom plate 211 extending inward. For the photovoltaic component fixing structure for seamless installation, the frames 21 of two photovoltaic components adjacent to each other in the transverse direction are arranged in close contact. The photovoltaic component fixing structure also includes a waterproof buckle 1, the upper portion of the waterproof buckle 1 is provided with a slot 12 with a lateral opening, the bottom plate 211 is engaged in the slot 12, the lower portion of the waterproof buckle 1 is provided with a lower fixing buckle, the beam 3 is provided with a fixing portion, and the lower fixing buckle is fixed to the fixing portion.

[0038] Since the frames of two laterally adjacent photovoltaic modules are fitted together without leaving any gaps, they are waterproof and there is no need to set up waterproof blocking strips. This solves the need for seamless installation of photovoltaic systems on flat roofs, especially sloping roofs, and reduces water leakage problems.

[0039] The photovoltaic module is fixed to the crossbeam by a waterproof buckle, wherein the slot provided on the upper part of the waterproof buckle clamps and fixes the bottom plate, and the lower fixing buckle provided on the lower part of the waterproof buckle is fixed to the fixing part on the crossbeam. During installation, the waterproof buckle clamps the bottom plate of the bottom frame of the photovoltaic module through the slot and fixes it as a whole with the photovoltaic module, and then the photovoltaic module is installed on the crossbeam, and the lower fixing buckle is fastened with the fixing part on the crossbeam. Compared with the existing waterproof pressure block fastened by bolts, it is simple and easy to operate, and the installation efficiency is improved; since no bolts are required and the amount of pressure blocks used is small, the cost can be reduced.

[0040] Specifically, the clamping slot 12 is provided with a lower clamping edge 121 and an upper clamping edge 122, wherein the lower clamping edge 121 is supported on the bottom surface of the bottom plate 211, and the upper clamping edge 122 is pressed on the top surface of the bottom plate 211. The upper clamping edge 122 is provided with a pressing portion 1221 pressed on the top surface of the bottom plate and a bending portion 1223 connecting the pressing portion and the lower clamping edge, and the bending portion 1223 enables the pressing portion 1221 to generate a clamping force to cooperate with the lower clamping edge 121 to clamp the bottom plate 211, thereby ensuring reliable clamping of the bottom plate.

[0041] Furthermore, the pressing part 1221 is provided with a pressing protrusion 1222. The longitudinal width of the pressing part 1221 is greater than the longitudinal width of the beam. Since the longitudinal width of the pressing part is greater than the longitudinal width of the beam, the pressing part and the bottom plate have a larger effective area, and the pressing protrusion can increase the friction between the bottom plate edge, further improve the pressing stability, avoid looseness, and ensure the clamping of the bottom plate.

[0042] In this embodiment, the cross beam 3 is a C-shaped steel or a U-shaped steel. The fixing portion is an inner fixed rib 31 provided inside the mouth of the C-shaped steel or the U-shaped steel, and the lower fixing buckle includes side spring pieces 13 provided on both sides of the waterproof buckle, and the upper ends of the side spring pieces 13 are fixed with the inner fixed rib 31. When installing in this way, the lower fixing buckle is pressed downward into the inside of the cross beam, and the side spring pieces shrink and deform during the pressing process. After being pressed into the cross beam, they expand outward, and finally the upper ends of the side spring pieces cooperate with the inner fixed rib to achieve clamping fixation. No tools are required during the installation process, which facilitates quick installation.

[0043] Specifically, the inner fixed retaining edge 31 is folded inward to form a limiting groove, and the side spring piece 13 extends from the bottom to the oblique upward direction and is provided with a limiting edge 131 that is inserted into the limiting groove at the upper end. After the side spring piece that is finally pressed into the inner side of the beam expands outward, the limiting edge at its upper end is inserted into the limiting groove to form a limiting fit to prevent the lower fixed buckle from separating upward from the beam. The lower part of the waterproof buckle 1 is provided with a fixed block 11 inserted into the inner side of the beam, and the lower fixed end of the side spring piece is connected to the bottom side of the fixed block to form an integrated structure. After the fixed block is inserted into the inner side of the beam from top to bottom, the side spring piece returns to its original state, and the limiting edge is inserted into the limiting groove to fix the upper and lower positions of the entire waterproof buckle.

[0044] It is understandable that the matching structure between the lower fixing buckle and the fixing part on the cross beam is not limited to the above-mentioned embodiment. For example, the lower fixing buckle is an elastic hook, and the fixing part is a hole. After the hook passes through the hole, it returns to its original shape to complete the fixation.

[0045] Preferably, the waterproof buckle 1 is a profile with an integrated structure, such as an aluminum alloy profile, which is extruded to achieve industrialized production, significantly reduce costs, and has high strength and long service life.

[0046] In addition to the above description, the entire photovoltaic module fixing structure also has other parts. The cross beams are cross-fixed on the longitudinal beams. In addition, a drainage structure is also provided. Please refer to the prior art for the structure of other parts, which will not be repeated here.

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
