Wherein, a set of clamping devices 12 can be arranged on the frame 20 at intervals of 1-1.5 meters, thereby ensuring that the coaming 11 can be connected with the frame 20 stably.

Referring to fig. 4, the clamping member 122 may include a first mounting portion 1222, a second mounting portion 1223, and a third mounting portion 1224 connected to each other, wherein the first mounting portion 1222 and the third mounting portion 1224 are disposed perpendicular to the second mounting portion 1223, and the first mounting portion 1222, the second mounting portion 1223, and the third mounting portion 1224 enclose an opening 1221.

Specifically, when the horizontal edges of the first segment 1211 and the frame 20 are received in the opening 1221 of the clamping member 122, the first portion 111 may be inserted between the second segment 1212 and the third segment 1213 and the frame 20 through the V-port until the first portion 111 abuts against the first segment 1211, at which time the second portion 112 may abut against the third segment 1213. The fixing piece 123 on the movable clamping piece 122 enables the fixing piece 123 to prop against the first section 1211, so that the backup plate 121 and the frame 20 are propped against each other, the first portion 111 is fixedly pressed through friction force between the second section 1212 and the third section 1213 and the vertical face of the frame 20, and therefore the coaming 11 is guaranteed to be firmly fixed on the frame 20.

The length of the direct member 132 may be 199.8mm to 200.2mm (not shown). The length L9 of the first plate 1321 may be 20.3mm to 20.7mm, the length L10 of the second plate 1322 may be 11.7mm to 12.1mm, and the chord length L11 of the third plate 1323 may be 115.3mm to 115.7mm. The dimension of the direct member 132 is controlled within a proper range, so that the direct member 132 can better cover the coaming 11 while avoiding waste of materials, and the direct pressing plate 131, the direct member 132 and the coaming 11 are more attached.

It should be noted that, when the straight connecting device 13 is installed, the straight pressing plate 131 can be slid to the connection position of the adjacent two coamings 11 on the same side of the frame 20 through the first mounting groove 1311 on the straight pressing plate 131, so that the portions of the fourth portions 114 of the adjacent two coamings 11 are all accommodated in the first mounting groove 1311, and a space is left between the third portions 113 of the two coamings 11 and the first vertical plate 1312. The third plate 1323 of the direct member 132 is then inserted between the third portion 113 and the first standing plate 1312, thereby ensuring that the two coamings 11, the direct press plate 131 and the direct member 132 on the same side of the rim 20 are tightly connected together. The deformation of the coaming plates 11 is adjusted through the straight pressing plates 131, so that two adjacent coaming plates 11 form a straight line, and then the direct piece 132 is used for reinforcing and sealing joints from the outside of the coaming plates 11, so that the coaming plates have the effects of stability and attractive appearance.

Example nine

Wherein the first cover 1411 includes a fourth plate 14111, a fifth plate 14112, and a sixth plate 14113, which are sequentially connected, and the second cover 1412 includes a seventh plate 14121, an eighth plate 14122, and a ninth plate 14123, which are sequentially connected.

When the corner piece 141 covers two of the coamings 11 that are adjacent and connected at right angles, the fourth plate 14111 covers the first portion 111 of one of the coamings 11, the fifth plate 14112 covers the second portion 112 of one of the coamings 11, and the sixth plate 14113 covers the third portion 113 of one of the coamings 11; the sixth plate 14113 covers the first portion 111 of the other shroud 11, the seventh plate 14121 covers the second portion 112 of the other shroud 11, and the eighth plate 14122 covers the third portion 113 of the other shroud 11.

Referring to fig. 17-20, the width W7 of the corner member 141 may be 129.8 mm-130.2 mm, the height H9 of the corner member 141 may be 115.3 mm-115.7 mm, and the thickness D7 of the corner member 141 may be 0.3 mm-0.7 mm. The length L12 of the fourth plate 14111 and the seventh plate 14121 can be 20.3mm to 20.7mm, the length L13 of the fifth plate 14112 and the eighth plate 14122 can be 11.7mm to 12.1mm, and the chord length L14 of the sixth plate 14113 and the ninth plate 14123 can be 115.3mm to 115.7mm. The size of the corner piece 141 is controlled within a reasonable range, so that the corner piece 141 can be guaranteed to better cover the joint of the two coamings 11 at the corner to ensure attractive appearance.

It is understood that the number of corner pieces 141 and corner pressing plates 142 may be 4, that is, 1 corner piece 141 and 1 corner pressing plate 142 are disposed at the corners of the rectangular photovoltaic system 100. The corner pieces 141 and the corner pressing plates 142 may be made of metal materials to ensure rigidity of the corner pieces 141 and the corner pressing plates 142, for example, stainless steel materials may be selected. In addition, the outer surfaces of the straight corner member 141 and the corner pressing plate 142 may be painted, and the specific color may be selected according to the overall structure of the photovoltaic system 100, which is not limited herein.

It should be noted that, when the corner connecting device 14 is installed, the second installation groove 1421 and the third installation groove 1422 on the corner pressing plate 142 can be used to respectively accommodate the fourth portions 114 of two adjacent coamings 11 at the corner of the frame 20, and a space is reserved between the third portion 113 and the second vertical plate 1423 of one coaming 11, and a space is reserved between the third portion 113 and the third vertical plate 1424 of the other coaming 11. The sixth plate 14113 of the corner piece 141 is then inserted between the third portion 113 and the second riser 1423, while the ninth plate 14123 of the corner piece 141 is inserted into the third portion 113 and the third riser 1424. Thereby ensuring that the adjacent two coamings 11, the turning plate and the corner piece 141 at the corner of the frame 20 are tightly connected together. The deformation of the coaming 11 is adjusted through the rotating pressing plate, and the joint is reinforced and covered by the corner piece 141 from the outside of the coaming 11, so that the coaming 11 has the functions of stability and attractive appearance.
