When the number of third cover bodies is one, the third cover body is connected and matched with the adjacent second cover body 140, and when the number of third cover bodies is at least two, one of the at least two third cover bodies is connected and matched with the adjacent second cover body 140, and the remaining third cover bodies are respectively connected and matched with the adjacent third cover bodies.

[0124] Specifically, the second cover body 140 further comprises a third mounting portion for connecting and cooperating with an adjacent third cover body. The third mounting portion is connected to a second end of the second cover plate, the second end of the second cover plate being an end of the second cover plate 141 facing the third cover body, and the third mounting portion being located on a side of the second cover plate 141 facing the inside of the box body 100. The number of mounting racks 170 is at least two, the number of third cover bodies is N, and the number of mounting racks 170 is N+1. For example, when the number of third cover bodies is one, the number of mounting racks 170 is two, and when the number of third cover bodies is two, the number of mounting racks 170 is three. A part of the plurality of first connecting members 160 connects at least one mounting rack 170 and the third mounting portion.

[0125] Further, the third cover body is connected to the main body 110, and the third cover body comprises a third cover plate and a fourth mounting portion. The third cover plate is used to cover a part of the box opening 111, and the third cover plate is connected to the main body 110. The fourth mounting portion is connected to a first end of the third cover plate, and the fourth mounting portion is located on a side of the third cover plate facing the inside of the box body 100, so as to hide the fourth mounting portion inside the box body 100. The first end of the third cover plate is an end of the third cover plate facing the second cover plate 141, and the first end of the third cover plate abuts against the second end of the second cover plate. In this way, the structures for connection in the second cover body 140 and the third cover body (i.e., the third mounting portion and the fourth mounting portion) can be hidden inside the box body 100, and the exposed connecting structures such as fixing screws between the second cover body 140 and the third cover body can be hidden, so that the appearance of the box body 100 is simple, beautiful and consistent.

[0126] Further, the fourth mounting portion is connected to the third mounting portion, so that the connection of the second cover body 140 and the third cover body can be realized through the cooperation of the third mounting portion and the fourth mounting portion, so as to form an integral structure of the second cover body 140 and the third cover body, and improve the stability and integrity of the box body 100.

[0127] By providing at least one third cover body in the box body 100, the box opening 111 can be closed by the first cover body 120, the second cover body 140 and the third cover body. When the volume of the box body 100 is large, a larger number of cover bodies are provided, which can reduce the processing cost of a single cover body and improve the installation stability of the first cover body 120, the second cover body 140 and the third cover body.

[0128] In some embodiments, optionally, when the number of third cover bodies is at least two, at least one third cover body of the at least two third cover bodies further comprises a fifth mounting portion connected to a second end of the third cover plate, the fifth mounting portion being located on a side of the third cover plate facing the inside of the box body 100, and the fifth mounting portion being used to connect with the fourth mounting portion of an adjacent third cover body.

[0129] In the embodiment, the structure of the box 100 is further limited. In the case that the number of the third covers is at least two, at least one of the at least two third covers further comprises a fifth mounting portion for connecting with the fourth mounting portion of the adjacent third cover to connect the two adjacent third covers. Specifically, the fifth mounting portion is connected to the second end of the third cover plate, the second end of the third cover plate abuts against the first end of the adjacent third cover plate, and the fifth mounting portion is located on the side of the third cover plate facing the inside of the box 100. In this way, the fifth mounting portion can be hidden, and compared with the prior art, the connecting structure such as fixing screws exposed between the two adjacent third covers can be hidden, so that the appearance of the box 100 is simple, beautiful and consistent.

[0130] The second aspect of the utility model further provides a photovoltaic device, including the box 100 of the first aspect of the utility model.

[0131] The photovoltaic device provided by the second aspect of the utility model has all the beneficial effects of the box 100 because it comprises the box 100 provided by the first aspect of the utility model.

[0132] The third aspect of the utility model further provides an electrical equipment, including the box 100 of the first aspect of the utility model.

[0133] The electrical equipment provided by the third aspect of the utility model has all the beneficial effects of the box 100 because it comprises the box 100 provided by the first aspect of the utility model.

[0134] In a possible embodiment, when assembling the box 100, first, the circular sealing ring (i.e., the first sealing member 180 and the second sealing member 190) is sleeved into the semicircular groove on the side of the special sealing member. Then, the special sealing member with the sealing ring is pressed into the front of the mouth of the box 100 to the designed reasonable position. Then, the screws are screwed on the side of the box 100 to limit the movement of the special sealing member. Then, the top cover (i.e., the first cover 120 and the second cover 140) is covered, the screws are screwed on the side to fix the top cover, and the assembly is completed.
