As shown in fig. 3, a bearing mechanism is installed on one side of the second side plate 1021 near the first frame 101, that is, near the battery plate subsection 100, and the battery plate subsection 100 and the second frame 102 are connected through the bearing mechanism. The side of the second side plate 1021 remote from the first frame 101, that is, the side remote from the battery plate subsection 100, is provided with a first water guiding trough 1022, and the first water guiding trough 1022 and the battery plate subsection 100 are oppositely arranged on two sides of the second side plate 1021. The first water guiding channel 1022 is disposed along the length direction of the second frame 102, the length of the first water guiding channel 1022 is the same as that of the second frame 102, and a certain distance extends from the bottom of the first water guiding channel 1022 to a direction away from the second side plate 1021 (away from the first frame opposite to the second frame), so as to form the first water guiding channel 1022 with a certain width. The first water guiding trough 1022 is provided with a notch along the length direction, the notch along the length direction faces the upper surface of the photovoltaic module, and meanwhile, the two ends of the first water guiding trough 1022 are open, so that rainwater in the first water guiding trough 1022 can be discharged through the openings at the two ends. The first water chute 1022 may be located at an end of the second side panel 1021 remote from the cell segment 100, i.e., at the bottom of the photovoltaic module. The first water guide channel 1022 may 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 channel 1022. Alternatively, the first water guide channel 1022 may be connected to the second side plate 1021 by welding or the like, and when the first water guide channel 1022 is connected to the second side plate 1021 by welding or the like, the second side plate 1021 and the first water guide channel 1022 are hermetically connected. The first water chute may be a rectangular chute as shown in fig. 3, or may be a water chute with other shapes, and the structure of the first water chute is not limited in this embodiment.

In this embodiment, in a case where the first rim 101 is assembled with the second rim 102, the first bridging plate 1012 may shield the notch of the first water chute 1022 in the length direction. As shown in fig. 1, in the use process of the photovoltaic array, the first frame 101 and the second frame 102 splice two adjacent photovoltaic modules left and right, so that the first frame 101 and the second frame 102 form an assembled state as shown in fig. 3 between the two adjacent photovoltaic modules left and right. At this time, the first bridging plate 1012 in one photovoltaic module extends to the second side plate 1021 in the other photovoltaic module, the first water chute 1022 is located between the two photovoltaic modules (between the first side plate 1011 and the second side plate 1021), and the first bridging plate 1012 is located above the first water chute 1022, and the distance between the two photovoltaic modules is adjusted, so that the first bridging plate 1012 can shield part or all of the notch of the first water chute 1022. Between two adjacent photovoltaic modules on the left and right, rainwater may enter the first water guiding gutter 1022 through a gap between the first bridging plate 1012 and the second side plate 1021, and be discharged through the first water guiding gutter 1022. At this time, the third frame 103 and the fourth frame 104 are spliced with two adjacent photovoltaic modules, and the two adjacent photovoltaic modules can be spliced in a lap joint manner (i.e. the photovoltaic module above is lapped on the photovoltaic module below), or spliced in a traditional sealing strip and sealing glue manner.

In summary, in this embodiment, the first bridging plate is disposed on one side of the first frame, the first water guiding groove is disposed on one side of the second frame, and when the first frame is assembled with the second frame, the first bridging plate can enable rainwater between two adjacent photovoltaic modules (i.e., between the first frame and the second frame) to directly flow into the first water guiding groove, and the rainwater is discharged through the first water guiding groove, so that the waterproof problem between two adjacent photovoltaic modules can be solved. In the installation process of the photovoltaic array, a large number of sealing strips can be prevented from being arranged between adjacent photovoltaic modules, and sealant is coated, so that the installation efficiency of the photovoltaic modules can be improved. And in the use process of the photovoltaic array, the hidden danger of water leakage caused by aging of the sealing strips and the sealing glue can be avoided. Simultaneously, through adjusting the interval between first frame and the second frame, can adjust the distance between two adjacent photovoltaic module in a flexible way, make things convenient for photovoltaic module's dismantlement and installation.

Optionally, a shape of a side of the first water guiding trough 1022 facing away from the second frame 102 is matched with a shape of a side of the first frame 101 facing away from the second frame 102, and when the first frame 101 is assembled with the second frame 102, a side of the first water guiding trough 1022 facing away from the second frame 102 abuts against the first frame 101, or a first preset distance is formed between a side of the first water guiding trough 1022 facing away from the second frame 102 and the first frame 101.

For example, as shown in fig. 3, a shape of a side of the first water guiding groove 1022 facing away from the second side plate 1021 is matched with a shape of a side of the first side plate 1011 facing away from the battery tab subsection 100, and when the first frame 101 is assembled with the second frame 102, a side of the first water guiding groove 1022 facing away from the second side plate 1021 abuts against the first side plate 1011, or a first preset distance is formed between a side of the first water guiding groove 1022 facing away from the second side plate 1021 and the first side plate 1011.

In this embodiment, the structure of the first water chute 1022 may match the structure of the first side plate 1011 to form a stable photovoltaic array. For example, the first water guiding trough 1022 may be a rectangular water guiding trough, a side wall of the first water guiding trough 1022 far from the second side plate 1021 may be a straight wall, and a side of the first side plate 1011 adjacent to the first water guiding trough 1022 is a straight wall. In the case that the first frame 101 and the second frame 102 are assembled, the first water chute 1022 may abut against the first side plate 1011, so that the first frame 101 and the second frame 102 are tightly fitted, and thus a stable fitting state is formed between adjacent photovoltaic modules. Or the first water guiding trough 1022 may also be spaced from the first side plate 1011 by a first preset distance, so as to adjust the distance between the two photovoltaic modules. The specific value of the first preset distance may be set according to requirements, and this embodiment does not limit this.

Optionally, a second strap 1023 is arranged on the side of the first water chute 1022 opposite to the second frame 102, the second strap 1023 extends in the direction close to the second frame 102, and when the first frame 101 and the second frame 102 are assembled, the second strap 1023 abuts against the first strap 1012, or the second strap 1023 and the first strap 1012 are spaced by a second preset distance.

For example, as shown in fig. 3, a second strap 1023 is disposed on a side of the first water chute 1022 opposite to the second side plate 1021, the second strap 1023 extends in a direction close to the second side plate 1021, and in a case where the first frame 101 and the second frame 102 are assembled, the second strap 1023 abuts against the first strap 1012, or the second strap 1023 and the first strap 1012 are spaced apart by a second predetermined distance.

In this embodiment, the second bridging plate 1023 can be disposed on the side wall of the first water guiding trough 1022 far away from the second side plate 1021, the second bridging plate 1023 is disposed at the notch position of the first water guiding trough 1022 along the length direction, and the second bridging plate 1023 extends out to a certain distance in the direction close to the second side plate 1021, so as to shield the partial notch of the first water guiding trough 1022. In practical applications, the height of the sidewall of the first water chute 1022 may be adjusted so that the second strap 1023 abuts the first strap 1012 when the first frame 101 and the second frame 102 are assembled. When the second bridging plate 1023 abuts against the first bridging plate 1012, the first bridging plate 1012 can be supported by the second bridging plate 1023, and then the first frame 101 is supported by the second frame 102, so that two adjacent photovoltaic modules are tightly matched. Meanwhile, when the second bridging plate 1023 is arranged at the notch of the first water chute 1022, rainwater in the first water chute 1022 can be prevented from entering the bottom of the photovoltaic array from a gap between the first side plate 1011 and the first water chute 1022 after overflowing from the notch of the first water chute 1022.

The structure of the second water chute 1033 can refer to the first water chute 1022, which is not limited by the embodiment. The third bridging plate 1032 is close to the upper surface of the photovoltaic module, and the second water chute 1033 is far away from the upper surface of the photovoltaic module, so that the third bridging plate 1032 is located at the position of the notch of the second water chute 1033, and the width of the third bridging plate 1032 is smaller than that of the second water chute 1033, and the third bridging plate 1032 can only shield part of the notch of the second water chute 1033.

And the width of the fifth bridging plate 1043 may be adjusted, so that the fifth bridging plate 1043 may shield a part or all of the notches of the second water chute 1033 in the length direction. In practical application, when rainwater enters from between the third bridging plate 1032 and the fourth bridging plate 1042, the rainwater may enter the bottom of the photovoltaic array from the gap between the second water chute 1033 and the fourth side plate 1041 under the action of the third bridging plate 1032, the fifth bridging plate 1043 is arranged to shield the notch of the second water chute 1033, so that the rainwater can be introduced into the second water chute 1033, and the rainwater is prevented from entering the bottom of the photovoltaic array from the gap between the second water chute 1033 and the fourth side plate 1041.

Because the third rim 103 is located below the fourth rim 104, in the installation and use process of the photovoltaic module, the fourth rim 104 can be supported by the second water chute 1033, so that the photovoltaic module located above is supported by the photovoltaic module located below, and the installation of the photovoltaic module is facilitated.
