Meanwhile, the top edge of the trapezoid is a plane, and the trapezoid can be used for mounting other components and the like.

In other embodiments, the protruding portion 111 and the fitting portion 121 may be formed in a triangular shape or a semicircular shape according to different requirements and situations, as long as it is ensured that they are protruded in the vertical direction and the adjacent library plates 100 are overlapped with each other.

As shown in fig. 5, the joints of the first bending portion 112, the second bending portion 113 and the first transition portion 114 are arc-shaped chamfers, and the joints of the third bending portion 122, the third connecting portion and the second transition portion 124 are also arc-shaped chamfers. The structure can increase the strength of the joint, facilitate rainwater to flow down from the second transition part 124 to two sides, and simultaneously enable the protruding part 111 and the matching part 121 to be more attached in a superposed state, thereby further improving the water tightness.

As shown in fig. 5, the outer wall of the first bent portion 112 of the protruding portion 111 abuts against the inner wall of the fourth bent portion 123 of the fitting portion 121. The waterproof function can be achieved, and the rainwater level of the power station is prevented from rising when the power station is in a rain accumulation state, and the rainwater level can be prevented from permeating into the interior of the warehouse board 100 from the gap.

As shown in fig. 5, at the overlapping structure of the protrusion 111 and the fitting part 121, there is a gap between the first laminate 101 and the second laminate 102. At the raised end 110 of the library board 100, the edge portion of the second layer board 102 is bent toward the first layer board 101, and the edge portion of the first layer board 101 is bent toward the second layer board 102. The inner surface of the edge portion of the first layer plate 101 is attached to the outer surface of the edge portion of the second layer plate 102 to form a staggered structure to enclose the inner cavity between the first layer plate 101 and the second layer plate 102.

As shown in fig. 5, at the mating end 120 of the library board 100, the edge portion of the second layer board 102 is bent and extended toward the first layer board 101, and the edge portion of the second layer board 102 is interposed between the edge portion of the first layer board 101 and the side surface of the protrusion 111 of the adjacent library board 100 close to the mating end 120. The outer surface of the edge portion of the second ply 102 simultaneously abuts the outer surface of the edge portion of the first ply 101 of the raised end 110 of the adjacent library panel 100. The second laminate 102 is firstly attached to the edge part of the first laminate 101 of the adjacent warehouse board 100, then continues to extend upwards, and is filled between the first laminate 101 and the first laminate 101 of the adjacent warehouse board 100, so that the warehouse board 100 forms a closed structure at the mating end 120, meanwhile, the joint of the two warehouse boards 100 is smaller, and water is prevented from permeating into the battery replacement station from the joint.

As shown in fig. 5, the top of the protrusion 111 has a groove (not shown) extending along the extending direction of the library board 100, and the sealing strip 160 is installed in the groove, and one side of the sealing strip 160 is clamped in the groove, and the other side of the sealing strip abuts against the inner side of the top of the matching portion 121. The sealing strip is arranged between the top of the protruding portion 111 and the top of the matching portion 121, when rainwater accumulates on the combined unit of the warehouse board 100, water rises from a gap between the protruding portion 111 and the matching portion 121, and then is blocked by the sealing strip 160 arranged at the top, and the water cannot permeate into the power conversion station, so that the waterproofness of the combined unit of the warehouse board 100 is improved.

In this embodiment, the sealing strip 160 is a rubber strip, and in other embodiments, the sealing strip 160 may be disposed at an entrance of the joint portion of the protruding portion 111 and the matching portion 121, or made of other waterproof materials.

In this embodiment, the raised ends 110 and mating ends 120 of the library board 100 are aligned in a first direction. Two end faces perpendicular to the first direction on the storage plate 100 are side face parts 130, and the side face parts 130 are used for closing two end parts of the storage plate 100 along the direction perpendicular to the first direction, namely, the first layer plate 101, the second layer plate 102 and the side face parts 130 form a closed cavity. The portion of the side portion 130 at the protruding end 110 is a first side panel, and the portion of the side portion 130 at the mating end 120 is a second side panel. The second side panel covers the partial outside of the first side panel of the adjacent library board 100, and the first side panel is spliced and wrapped, so that the seams of the two are staggered, and liquid is prevented from permeating into the library board 100 from the seams on the sides of the two library boards 100.
