[0002] Compared with traditional power generation technology, photovoltaic power generation has the advantages of abundant energy, simple power generation process, no noise, and no pollution. Building Integrated Photovoltaic (BIPV) is a technology that integrates photovoltaic arrays (photovoltaic arrays are composed of multiple photovoltaic modules) into buildings, such as photovoltaic tile roofs, photovoltaic curtain walls, and photovoltaic skylights.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Reference Figure 1 , Figure 1 A schematic diagram of a photovoltaic array in an embodiment of the present invention is shown. Figure 1As shown, the photovoltaic array is composed of multiple photovoltaic modules, which are mounted on a bracket 200. The photovoltaic module includes a cell section 100 and a BIPV waterproof component located around the cell section 100. The BIPV waterproof component includes a frame section and an overlap section. The cell section 100 is assembled from multiple battery strings, a photovoltaic module back plate, and a photovoltaic module front plate. For an understanding of the cell section 100 and the photovoltaic module, reference may be made to the prior art.

[0045] Reference Figure 2 and Figure 3 , Figure 2 A front view of a BIPV waterproof component in an embodiment of the present invention is shown. Figure 3 The schematic diagram of the assembly of a first frame and a second frame in an embodiment of the present invention is shown. The frame section includes a first frame 101 and a second frame 102 arranged opposite to each other, and the overlap section includes a first overlap plate 1012 and a first water guide groove 1022 .

[0046] For example, the frame division may also include a third frame 103 and a fourth frame 104 that are arranged opposite to each other. The first frame 101, the second frame 102, the third frame 103 and the fourth frame 104 may be connected end to end in sequence by welding, bolt connection or snap connection, and form a rectangular frame division around the battery cell division 100. Among them, a side of the first frame 101 close to the battery cell division 100, a side of the second frame 102 close to the battery cell division 100, a side of the third frame 103 close to the battery cell division 100, and a side of the fourth frame 104 close to the battery cell division 100 are respectively provided with a bearing mechanism, and the battery cell division 100 is fixed in the frame division by the bearing mechanism. The first frame 101, the second frame 102, the third frame 103 and the fourth frame 104 may be made of a metal material with high strength such as aluminum alloy and stainless steel. The specific structure of the supporting mechanism, the specific shape of the frame division, the connection method between the first frame, the second frame, the third frame and the fourth frame, etc. can be set according to needs, and this embodiment does not impose any restrictions on this.

[0047] In this embodiment, the first frame 101 and the second frame 102 are arranged on both sides of the cell section 100. The first frame 101 and the second frame 102 are used to splice two adjacent photovoltaic modules while supporting the cell section 100. Figure 1 and Figure 3 In two adjacent photovoltaic modules, the first frame 101 of one photovoltaic module is assembled with the second frame 102 of the other photovoltaic module to splice the two adjacent photovoltaic modules together.

[0048] For example, the first frame 101 includes a first side plate 1011 , which constitutes the main body of the first frame 101 . A first lap plate 1012 is provided on the side of the first side plate 1011 away from the second frame 102 , and the first lap plate 1012 extends in a direction away from the second frame 102 .

[0049] like Figure 3 As shown, a bearing mechanism is installed on the side of the first side plate 1011 close to the second frame 102, that is, the side close to the battery cell section 100, and the battery cell section 100 and the first frame 101 are connected by the bearing mechanism. A first lap plate 1012 is arranged on the side of the first side plate 1011 away from the second frame 102, that is, the side away from the battery cell section 100, and the first lap plate 1012 and the battery cell section 100 are arranged on both sides of the first side plate 1011 opposite to each other. The first lap plate 1012 intersects with the first side plate 1011, and the first lap plate 1012 is arranged along the length direction of the first side plate 1011, and the length of the first lap plate 1012 is the same as that of the first frame 101. The first lap plate 1012 extends a certain distance in the direction away from the first side plate 1011 (away from the second frame opposite to the first frame), forming a first lap plate 1012 with a certain width. The first lap plate 1012 is located on the upper surface of the photovoltaic module (the upper surface of the photovoltaic module is the side of the photovoltaic module that receives sunlight), or a certain distance from the upper surface of the photovoltaic module. The position of the first lap plate 1012 in the first side plate 1011 can be set according to demand. The first lap plate 1012 can be perpendicular to the first side plate 1011 to form a regular first frame 101. The first lap plate 1012 and the first side plate 1011 can be integrally formed, or they can be connected by welding or the like. It should be noted that when the first lap plate 1012 and the first side plate 1011 are connected by welding or the like, the first lap plate 1012 and the first side plate 1011 are sealed.

[0050] For example, the second frame 102 includes a second side plate 1021 , which constitutes a main body of the second frame 102 , and a first water guide groove 1022 is provided on a side of the second side plate 1021 away from the first frame 101 and along the length direction of the second frame 102 .

[0051] like Figure 3As shown, a bearing mechanism is installed on the side of the second side plate 1021 close to the first frame 101, that is, the side close to the battery cell section 100, and the battery cell section 100 and the second frame 102 are connected by the bearing mechanism. A first water guide groove 1022 is provided on the side of the second side plate 1021 away from the first frame 101, that is, the side away from the battery cell section 100. The first water guide groove 1022 and the battery cell section 100 are arranged on both sides of the second side plate 1021 opposite to each other. The first water guide groove 1022 is arranged along the length direction of the second frame 102, and the length of the first water guide groove 1022 is the same as the length of the second frame 102. The bottom of the first water guide groove 1022 extends a certain distance in the direction away from the second side plate 1021 (away from the first frame opposite to the second frame), forming a first water guide groove 1022 with a certain width. The first water guide groove 1022 is provided with slots along the length direction, and the slots along the length direction face the upper surface of the photovoltaic module. At the same time, both ends of the first water guide groove 1022 are open, and rainwater in the first water guide groove 1022 can be discharged through the openings at both ends. The first water guide groove 1022 can be located at an end of the second side plate 1021 away from the battery cell section 100, that is, located at the bottom of the photovoltaic module. The first water guide groove 1022 can be integrally formed with the second side plate 1021, and the second side plate 1021 constitutes one of the side walls of the first water guide groove 1022. Alternatively, the first water guide groove 1022 can also be connected to the second side plate 1021 by welding or the like. When the first water guide groove 1022 is connected to the second side plate 1021 by welding or the like, the second side plate 1021 and the first water guide groove 1022 are sealed. Among them, the first water guide groove can be as follows Figure 3 The rectangular groove shown may also be a water guide groove of other shapes. This embodiment does not limit the structure of the first water guide groove.

[0052] In this embodiment, when the first frame 101 and the second frame 102 are assembled, the first lap plate 1012 can cover the notch of the first water channel 1022 along the length direction. Figure 1 As shown, during the use of the photovoltaic array, the first frame 101 and the second frame 102 splice two adjacent photovoltaic components on the left and right, so that between the two adjacent photovoltaic components on the left and right, the first frame 101 and the second frame 102 form a Figure 3The assembly state shown. At this time, the first lap plate 1012 in one photovoltaic assembly extends to the second side plate 1021 in another photovoltaic assembly, the first water channel 1022 is located between the two photovoltaic assemblies (between the first side plate 1011 and the second side plate 1021), and the first lap plate 1012 is located above the first water channel 1022. By adjusting the distance between the two photovoltaic assemblies, the first lap plate 1012 can block part or all of the notches of the first water channel 1022. Between two photovoltaic assemblies adjacent to each other on the left and right, rainwater can enter the first water channel 1022 through the gap between the first lap plate 1012 and the second side plate 1021, and be discharged through the first water channel 1022. At this time, the third frame 103 and the fourth frame 104 splice the two photovoltaic assemblies adjacent to each other above and below, and the two photovoltaic assemblies adjacent to each other above and below can be spliced ​​in the form of overlap (that is, the photovoltaic assembly located above is overlapped on the photovoltaic assembly located below), or spliced ​​in the form of traditional sealing strips and sealants.

[0053] In summary, in this embodiment, a first lap plate is provided on one side of the first frame, and a first water guide groove is provided on one side of the second frame. When the first frame and the second frame are assembled, the rainwater between two adjacent photovoltaic modules (i.e., between the first frame and the second frame) can be directly flowed into the first water guide groove through the first lap plate, and discharged through the first water guide groove, thereby solving the waterproof problem between two adjacent photovoltaic modules. During the installation of the photovoltaic array, it is possible to avoid providing a large number of sealing strips and applying sealants between adjacent photovoltaic modules, thereby improving the installation efficiency of the photovoltaic modules. And during the use of the photovoltaic array, the hidden danger of water leakage caused by the aging of the sealing strips and sealants can be avoided. At the same time, by adjusting the spacing between the first frame and the second frame, the distance between two adjacent photovoltaic modules can be flexibly adjusted, which is convenient for the disassembly and installation of the photovoltaic modules.

[0054] Optionally, the side of the first water guide groove 1022 facing away from the second frame 102 matches the shape of the side of the first frame 101 facing away from the second frame 102. When the first frame 101 and the second frame 102 are assembled, the side of the first water guide groove 1022 facing away from the second frame 102 abuts against the first frame 101, or the side of the first water guide groove 1022 facing away from the second frame 102 is separated from the first frame 101 by a first preset distance.

[0055] For example, Figure 3As shown, the side of the first water guide groove 1022 facing away from the second side plate 1021 matches the shape of the side of the first side plate 1011 facing away from the battery cell section 100. When the first frame 101 and the second frame 102 are assembled, the side of the first water guide groove 1022 facing away from the second side plate 1021 abuts against the first side plate 1011, or the side of the first water guide groove 1022 facing away from the second side plate 1021 is spaced a first preset distance from the first side plate 1011.

[0056] In this embodiment, the structure of the first water channel 1022 can match the structure of the first side plate 1011 to form a stable photovoltaic array. For example, the first water channel 1022 can be a rectangular water channel, and the side wall of the first water channel 1022 away from the second side plate 1021 can be a straight wall, and the side of the first side plate 1011 adjacent to the first water channel 1022 is a straight wall. When the first frame 101 and the second frame 102 are assembled, the first water channel 1022 can abut the first side plate 1011, so that the first frame 101 and the second frame 102 are closely matched, so that a stable matching state is formed between adjacent photovoltaic modules. Or the first water channel 1022 can also be spaced apart from the first side plate 1011 by a first preset distance to facilitate adjustment of the distance between the two photovoltaic modules. The specific value of the first preset distance can be set according to demand, and this embodiment does not limit this.

[0057] Optionally, a second lap plate 1023 is provided on the side of the first water guide groove 1022 opposite to the second frame 102, and the second lap plate 1023 extends in a direction close to the second frame 102. When the first frame 101 and the second frame 102 are assembled, the second lap plate 1023 abuts against the first lap plate 1012, or the second lap plate 1023 is separated from the first lap plate 1012 by a second preset distance.

[0058] For example, Figure 3 As shown, a second lap plate 1023 is provided on the side of the first water guide groove 1022 opposite to the second side plate 1021, and the second lap plate 1023 extends in a direction close to the second side plate 1021. When the first frame 101 and the second frame 102 are assembled, the second lap plate 1023 abuts against the first lap plate 1012, or the second lap plate 1023 and the first lap plate 1012 are separated by a second preset distance.

[0059] In this embodiment, a second lap plate 1023 may be provided on the side wall of the first water channel 1022 away from the second side plate 1021, and the second lap plate 1023 is provided at the notch position of the first water channel 1022 along the length direction, and the second lap plate 1023 extends a certain distance in the direction close to the second side plate 1021, so as to cover part of the notch of the first water channel 1022. In practical applications, the height of the side wall of the first water channel 1022 can be adjusted, so that when the first frame 101 and the second frame 102 are assembled, the second lap plate 1023 can be made to abut against the first lap plate 1012. When the second lap plate 1023 abuts against the first lap plate 1012, the first lap plate 1012 can be supported by the second lap plate 1023, and then the first frame 101 can be supported by the second frame 102, so that two adjacent photovoltaic modules can be closely matched. At the same time, when the second lap plate 1023 is provided at the notch of the first water channel 1022, it can prevent rainwater in the first water channel 1022 from overflowing from the notch of the first water channel 1022 and entering the bottom of the photovoltaic array from the gap between the first side plate 1011 and the first water channel 1022. The second lap plate and the first lap plate can also be spaced apart by a second preset distance, so that the position of the photovoltaic module can be easily adjusted. The specific value of the second preset distance can be set according to demand, and this embodiment does not limit this.

[0060] Optionally, a barb structure 1013 is provided on one side of the first lap plate 1012 close to the first water channel 1022 , and part or all of the barb structure 1013 is located in the first water channel 1022 when the first frame 101 and the second frame 102 are assembled.

[0061] For example, Figure 4 As shown, Figure 4Another schematic diagram of assembling the first frame and the second frame in the embodiment of the present invention is shown, the barb structure 1013 can be arranged on the side of the first lap plate 1012 close to the first water channel 1022, the side wall height of the first water channel 1022 and / or the size of the barb structure 1013 can be adjusted, and when the first frame 101 and the second frame 102 are assembled, the end of the barb structure 1013 away from the first lap plate 1012 can be located in the first water channel 1022, that is, in the assembled state, the barb structure 1013 extends into the first water channel 1022. Combined with the above example, when the second lap plate 1023 is arranged on one side of the first water channel 1022, when the first frame 101 and the second frame 102 are assembled, the end of the barb structure 1013 away from the first lap plate 1012 is lower than the second lap plate 1023, so that the barb structure 1013 is located in the first water channel 1022. When the barb structure 1013 extends into the first water guide groove 1022 , the barb structure 1013 cooperates with the second lap plate 1023 to prevent the first frame 101 from being separated from the second frame 102 .

[0062] Reference Figure 5 , Figure 5 The schematic diagram of assembling a third frame and a fourth frame in an embodiment of the present invention is shown, and the overlap section further includes a third overlap plate 1302 and a fourth overlap plate 1042. The third overlap plate 1032 is installed on the side of the third frame 103 away from the fourth frame 104, and extends in a direction away from the fourth frame 104. The fourth overlap plate 1042 is installed on the side of the fourth frame 104 away from the third frame 103, and extends in a direction away from the third frame 103. When the third frame 103 and the fourth frame 104 are assembled, the fourth overlap plate 1042 is superimposed on the third overlap plate 1032.

[0063] For example, Figure 5As shown, the third frame 103 includes a third side plate 1031, which constitutes the main part of the third frame 103. A bearing mechanism is installed on the side of the third side plate 1031 close to the fourth side plate 1042 (the side close to the battery cell division 100), and the battery cell division 100 and the third frame 103 are connected by the bearing mechanism. A third lap plate 1032 is arranged on the side of the third side plate 1031 away from the fourth side plate 1042, that is, the side away from the battery cell division 100. The third lap plate 1032 intersects with the third side plate 1031, and the third lap plate 1032 has the same length as the third frame 103. At the same time, the third lap plate 1032 extends a certain distance in the direction away from the third side plate 1031 to form a third lap plate 1032 with a certain width. The connection relationship between the third lap plate 1032 and the third side plate 1031 can refer to the first lap plate 1012, and this embodiment will not be repeated. The third lap plate 1032 may be spaced a certain distance from the upper surface of the photovoltaic module, so that the fourth lap plate 1042 may be located above the third lap plate 1032 when the third frame 103 and the fourth frame 104 are assembled.

[0064] The fourth frame 104 includes a fourth side plate 1041, which constitutes the main part of the fourth frame 104. A bearing mechanism is installed on the side of the fourth side plate 1041 close to the third side plate 1032 (the side close to the battery cell section 100), and the battery cell section 100 and the fourth frame 104 are connected by the bearing mechanism. The understanding of the fourth lap plate 1042 can refer to the first lap plate 1012, which will not be described in detail in this embodiment. Among them, the fourth lap plate 1042 can be located on the upper surface of the photovoltaic module, so that when the third frame 103 and the fourth frame 104 are assembled, the fourth lap plate 1042 can be located above the third lap plate 1032.

[0065] Reference Figure 6 , Figure 6 The diagram shows a usage state of a third frame and a fourth frame in an embodiment of the present invention. The position of the third lap plate 1032 in the third side plate 1031 and the position of the fourth lap plate 1042 in the fourth side plate 1041 can be adjusted, and the widths of the third lap plate 1032 and the fourth lap plate 1042 can be adjusted, so that when the third frame 103 and the fourth frame 104 are assembled, the third lap plate 1032 and the fourth lap plate 1042 are staggered between the third frame 103 and the fourth frame 104, and the fourth lap plate 1042 is superimposed on the third lap plate 1032. Figure 1As shown, when the photovoltaic array is in a tilted state, the fourth frame 104 of the photovoltaic assembly located above can be plugged into the third frame 103 of the other photovoltaic assembly located below between the two adjacent photovoltaic assemblies, so as to reach a mating state. In the mating state, the fourth lap plate 1042 is superimposed on the third lap plate 1032. Since the photovoltaic matrix is ​​in a tilted state, rainwater on the surface of the photovoltaic assembly located above can flow along the fourth lap plate 1042 to the surface of the photovoltaic assembly located below. The third lap plate 1032 can prevent rainwater from entering between the third side plate 1031 and the fourth side plate 1041, thereby solving the waterproof problem between the two adjacent photovoltaic assemblies above and below.

[0066] In this embodiment, the first lap plate can make the rainwater between the two adjacent photovoltaic modules on the left and right flow directly into the first water channel and be discharged through the first water channel, thereby solving the waterproof problem between the two adjacent photovoltaic modules on the left and right. The third lap plate and the fourth lap plate can solve the waterproof problem between the two adjacent photovoltaic modules on the top and bottom. During the installation of the photovoltaic array, it is possible to avoid setting sealing strips and applying sealants between adjacent photovoltaic modules, thereby improving the installation efficiency of the photovoltaic modules, and during the use of the photovoltaic array, it is possible to avoid the hidden danger of water leakage caused by the aging of sealing strips and sealants. At the same time, it is possible to avoid splicing photovoltaic modules by overlapping each other, thereby avoiding the photovoltaic modules located above from blocking the photovoltaic modules located below, thereby improving the power generation efficiency of the photovoltaic modules.

[0067] Optionally, the overlapping portion may further include a sealing member, and when the third frame 103 and the fourth frame 104 are assembled, the sealing member is disposed between the third overlapping plate 1032 and the fourth overlapping plate 1042 .

[0068] For example, Figure 5 As shown, a groove 301 is provided on the third lap plate 1032 and / or the fourth lap plate 1042, and the seal includes a first section 302 and a second section 303, the first section 302 is fixed in the groove 301, one side of the second section 303 is fixedly connected to the first section 302, and when the third frame 103 and the fourth frame 104 are assembled, the other side of the second section 303 abuts against the third lap plate 1032 or the fourth lap plate 1042.

[0069] In this embodiment, at least one sealing member may be provided between the third lap plate 1032 and the fourth lap plate 1042 to seal the gap between the third lap plate 1032 and the fourth lap plate 1042. A groove 301 may be provided on a side of the fourth lap plate 1042 close to the third lap plate 1032, or a groove 301 may be provided on a side of the third lap plate 1032 close to the fourth lap plate 1042, and the sealing member is installed in the groove 301. When the third frame 103 and the fourth frame 104 are assembled, the sealing member may seal the gap between the third lap plate 1032 and the fourth lap plate 1042 to prevent rainwater from entering the bottom of the photovoltaic array from the gap between the third lap plate 1032 and the fourth lap plate 1042.

[0070] The seal may be a herringbone seal, including a first section 302 ( Figure 5 The first section 302 is fixed in the groove 301, one side of the second section 303 is fixedly connected to the first section 302, and the other side extends away from the groove 301. The size of the second section 303 is adjusted, and when the third frame 103 and the fourth frame 104 are assembled, the other side of the second section 303 can abut against the third lap board 1032, thereby sealing the third lap board 1032 and the fourth lap board 1042. In actual applications, the number of seals, the groove structure, and the structure of the seals can be set according to needs, and this embodiment does not limit this.

[0071] Optionally, the overlapping section may further include a second water channel 1033, which is installed on a side of the third frame 103 away from the fourth frame 104, and the second water channel 1033 is arranged along the length direction of the third frame 103. The third overlapping plate 1032 is located at a notch of the second water channel 1022 along the length direction, and the width of the third overlapping plate 1032 is less than the width of the second water channel 1033.

[0072] For example, Figure 5As shown, a second water channel 1033 can be provided below the third lap plate 1032, and rainwater entering between the third lap plate 1032 and the fourth lap plate 1042 can be received through the second water channel 1033. The structure of the second water channel 1033 can refer to the first water channel 1022, and this embodiment does not limit this. The third lap plate 1032 is close to the upper surface of the photovoltaic module, and the second water channel 1033 is far away from the upper surface of the photovoltaic module, so that the third lap plate 1032 is located at the notch position of the second water channel 1033, and the width of the third lap plate 1032 is less than the width of the second water channel 1033, and the third lap plate 1032 can only cover part of the notch of the second water channel 1033. When rainwater enters between the third lap plate 1032 and the fourth lap plate 1042, it can enter the second water channel 1033 along the third lap plate 1032 and be discharged through the second water channel 1033.

[0073] Optionally, a fifth lap plate 1043 is provided on the side of the fourth frame 104 facing away from the third frame 103, and the fifth lap plate 1043 extends in a direction away from the third frame 103. When the third frame 103 and the fourth frame 104 are assembled, the fifth lap plate 1043 blocks the notch of the second water guide groove 1033 along the length direction.

[0074] For example, Figure 5 and Figure 6 As shown, a fifth lap board 1043 parallel to the fourth lap board 1042 can be provided below the fourth lap board 1042, the fourth lap board 1042 and the fifth lap board 1043 are spaced a certain distance apart, and when the third frame 103 and the fourth frame 104 are assembled, the third lap board 1032 is located between the fourth lap board 1042 and the fifth lap board 1043. The width of the fifth lap board 1043 can be adjusted so that the fifth lap board 1043 can cover part or all of the notches of the second water guide groove 1033 along the length direction. In actual applications, when rainwater enters from between the third lap plate 1032 and the fourth lap plate 1042, under the action of the third lap plate 1032, rainwater may enter the bottom of the photovoltaic array from the gap between the second water gutter 1033 and the fourth side plate 1041. The fifth lap plate 1043 is set to block the notch of the second water gutter 1033, which can guide rainwater into the second water gutter 1033 and prevent rainwater from entering the bottom of the photovoltaic array from the gap between the second water gutter 1033 and the fourth side plate 1041.

[0075] Optionally, the side of the second water channel 1033 away from the third frame 103 matches the shape of the side of the fourth frame 104 away from the third frame 103 . When the third frame 103 and the fourth frame 104 are assembled, the side of the second water channel 1033 away from the third frame 103 abuts the fourth frame 104 .

[0076] For example, Figure 5 and Figure 6 As shown, the outer contour of the second water guide groove 1033 can be rectangular, and the width of the second water guide groove 1033 can be adjusted. When the third frame 103 and the fourth frame 104 are assembled, the second water guide groove 1033 can be away from the side wall of the third side plate 1031 and abut the fourth side plate 1041, so that the third frame 103 and the fourth frame 104 form a tight fit. Since the third frame 103 is located below the fourth frame 104, during the installation and use of the photovoltaic module, the fourth frame 104 can be supported by the second water guide groove 1033, so that the photovoltaic module located above can be supported by the photovoltaic module located below, which facilitates the installation of the photovoltaic module. It should be noted that the side of the second water guide groove 1033 away from the third side plate 1031 can also be spaced apart from the fourth side plate 1041 by a first fixed distance, so as to facilitate the adjustment of the distance between two upper and lower adjacent photovoltaic modules.

[0077] Optionally, a first support plate 1034 may be provided at the bottom of the second water guide groove 1033, and the first support plate 1034 extends in a direction away from the third lap plate 1032. When the third frame 103 and the fourth frame 104 are assembled, the first support plate 1034 abuts against the fourth side plate 1041. When the first support plate 1034 is provided at the bottom of the second water guide groove 1033, the contact area between the second water guide groove 1033 and the fourth side plate 1041 may be increased, and the supporting area of ​​the photovoltaic assembly located below to the photovoltaic assembly located above may be increased, thereby improving the stability of the photovoltaic array.

[0078] In this embodiment, when the second frame 102 and the third frame 103 are assembled, the first water guide groove 1022 is connected to the second water guide groove 1033 .

[0079] For example, Figure 7 and Figure 8 As shown, Figure 7 A schematic diagram of a splicing surface of a second frame in an embodiment of the present invention is shown, Figure 8 A schematic diagram of a splicing surface of a third frame in an embodiment of the present invention is shown, combined with Figure 4 The second side plate 1021 may include a first portion 401 and a second portion 402, wherein the second portion 402 is located on a side close to the first water channel 1022, and the second portion 402 is disposed at the bottom of the first water channel 1022, and the second portion 402 extends in a direction away from the bottom of the first water channel 1022. Figure 4 As shown, the first part 401 constitutes the main body of the first side plate 1011 , and the second part 402 is located on a side close to the first water channel 1022 . The first part 401 and the second part 402 are integrally formed, and the second part 402 is used to increase the thickness of the first side plate 1011 .

[0080] When the second frame 102 and the third frame 103 are spliced, the second frame 102 and the third frame 103 can be cut to form a matching splicing surface at one end of the second frame 102 and one end of the third frame 103. Figure 7 As shown, during the cutting process, a splicing surface corresponding to the third frame 103 is formed by the cut first part 401. At the same time, the second part 402 is retained, and the connection between the first water guide groove 1022 and the second water guide groove 1033 is realized by the second part 402 cooperating with the second water guide groove 1033. In the process of connecting the first water guide groove 1022 and the second water guide groove 1033, a sealant can be set between the second water guide groove 1033 and the second part 402 to prevent rainwater from entering the bottom of the photovoltaic array from the gap between the second water guide groove 1033 and the second part 402. In practical applications, the specific structure of the first part 401 and the second part 402 can be set according to demand, as long as a splicing surface can be formed during the cutting process and can cooperate with the second water guide groove 1033.

[0081] Optionally, the first side plate 1011 may include a third portion 403 and a fourth portion 404, wherein the fourth portion 404 is disposed on the first lap plate 1012 and extends in a direction away from the first lap plate 1012. Figure 4 As shown, the third portion 403 constitutes the main body of the first side plate 1011 , and the fourth portion 404 is used to increase the thickness of the third side plate 1031 .

[0082] Reference Fig. 9 , Fig. 9 A schematic diagram of a splicing surface of a first frame in an embodiment of the present invention is shown. In combination with the above examples, when splicing the first frame 101 and the third frame 103, the first frame 101 and the third frame 103 can be cut, and the fourth part 404 can be retained during the cutting process, and the third part 403 can be cut, and a splicing surface corresponding to the third frame 103 is formed by the cut third part 403. The retained fourth part 404 can cooperate with the second water guide groove 1033, and a sealant is provided between the second water guide groove 1033 and the fourth part 404, which can seal the end of the second water guide groove 1033 close to the first side plate 1011. In practical applications, the specific structures of the third part 403 and the fourth part 404 can be set according to requirements, and it is only necessary to form a splicing surface during the cutting process and to cooperate with the second water guide groove 1033. It should be noted that the end of the second water guide groove 1033 close to the first frame 101 can also be sealed by other methods, and this embodiment does not limit this.

[0083] Optionally, the overlapping portion may further include a core sleeve 500 . When two adjacent second frames 102 are assembled, the core sleeve 500 is disposed in two adjacent first water guide grooves 1022 , and a sealant layer is disposed between the outer wall of the core sleeve 500 and the inner wall of the first water guide groove 1022 .

When the photovoltaic assembly located above is spliced ​​with the photovoltaic assembly located below, the two adjacent first water guide grooves 1022 can be connected respectively through the sleeve core 500, and the rainwater in the first water guide groove 1022 located above is introduced into the first water guide groove 1022 located below, so as to prevent rainwater from flowing into the bottom of the photovoltaic array from the gap between the first water guide groove and the second water guide groove. In practical applications, two adjacent first water guide grooves can also be connected by other means, and this embodiment does not limit this. At the same time, when the second frame 102 is matched with the third frame 103, the side wall of the sleeve core 500 can be cut to form an interface 501 that matches the second water guide groove 1033, and the rainwater in the second water guide groove 1033 is introduced into the first water guide groove through the interface 501.

[0085] In this embodiment, the bearing mechanism may include a bearing plate 601 and a gusset plate 602.

When the cell section 100 is installed in the mounting groove, the gusset plate 602 is located on the light-facing side of the cell section 100 (the light-facing side is the side of the cell that receives sunlight), and the carrier plate 601 is located on the backlight side of the cell section 100 (the backlight side is the side away from the light-facing side). Meanwhile, sealant can be provided between the cell section 100 and the inner wall of the mounting groove to seal the gap between the cell section 100 and the mounting groove. Similarly, the carrier plate 601 and the buckle plate 602 are arranged side by side on the second side plate 1021 close to the first side plate 1011 .

When the first frame 101, the second frame 102, the third frame 103 and the fourth frame 104 are sequentially connected to form a frame section, the cell section 100 is installed in the installation groove, and the cell section 100 can be fixed on the inner side of the frame section to form a photovoltaic module.

[0088] Optionally, a carrier plate 601 is provided on one side of the first frame 101 close to the second frame 102, and on one side of the second frame 102 close to the first frame 101.

In addition, a sealant layer 703 may be provided between the cell division 100 and the first side plate 1011, and between the cell division 100 and the second side plate 1021 to seal the cell division 100 and the first side plate 1011 and the second side plate 1021. The connection method between the cell division 100 and the carrier plate 601 may be set as required, and this embodiment does not limit this.

[0091] Among them, when the connecting member 702 is structural adhesive, an isolation member 704 can be set between the structural adhesive and the sealant. The isolation member 704 is, for example, a foam rod. The isolation member 704 isolates the structural adhesive and the sealant to avoid reaction between the structural adhesive and the sealant, which affects the connection effect of the structural adhesive and the sealing effect of the sealant.

A sealant layer 703 is respectively provided between the battery cell section 100 and the third side plate 1031, and between the battery cell section 100 and the fourth side plate 1041.

[0094] In actual applications, when the cell section 100 is flush with the first side panel 1011, the second side panel 1021, the third side panel 1031, and the fourth side panel 1041, the surface of the entire photovoltaic array can be made smooth, avoiding dust accumulation on the surface of the photovoltaic module, thereby preventing dust from blocking the photovoltaic module and affecting the power generation efficiency of the photovoltaic module.

A fixing plate 603 may be provided on a side of the fourth side plate 1041 close to the third side plate 1031, and the fixing plate 603 extends in a direction away from the fourth side plate 1041.

[0097] Optional, such as Figure 3 As shown, a second support plate 604 can be disposed between the fixing plate 603 and the bearing plate 601 to support the bearing plate 601 and the fixing plate 603, thereby improving the strength of the first frame 101. The specific structure of the second support plate 604 can be set as required, and this embodiment does not limit this.
