[0031] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0032] Please refer to Figures 1-10 This embodiment provides a photovoltaic purlin support system, including a plurality of purlins 1, each purlin 1 located on the same inclined plane and distributed parallel to each other longitudinally. The upper part of each purlin 1 is connected to a plurality of clamping components 3 for fixing photovoltaic modules 2, and the lower part of each purlin 1 is connected to a plurality of corner connecting components 4. Each corner connecting component 4 has a support pier 5 connected to its bottom. By installing corner connecting components on the support piers and then fixing the purlins to the corner connecting components, the photovoltaic modules are fixed to the purlins by the clamping components. This achieves stable support for the photovoltaic modules even without main beams or columns, significantly reducing steel consumption and saving costs. Furthermore, by changing the height distribution of the support piers and adjusting the angle of the corner connecting components, the installation angle of the photovoltaic array can be adjusted.

[0033] In some specific implementation methods, such as Figure 2 As shown, in the transverse direction, the heights of the support piers for supporting purlins at the same height are equal; for example... Figure 1 As shown, in the longitudinal direction, the height of the support piers increases sequentially from the lowest to the highest point of the inclined plane. Thus, by arranging support piers of different heights, the tilt angle of the photovoltaic modules can be adjusted while maintaining a consistent tilt angle in the lateral direction. For example, as shown... Figure 1 As shown, in the longitudinal direction, there are two purlins 1, and the heights of the support piers corresponding to the two purlins 1 are 200mm and 321mm respectively; in the transverse direction, the interval between two adjacent support piers is 2000mm (measured with the vertical centerline of the support pier as the reference).

[0034] In some specific embodiments, the support pier 5 is a C25 plain concrete pier, which is convenient for prefabrication. As an example, the support pier 5 is cuboid in shape. Specifically, the support piers 5 are spaced 1395mm apart in the longitudinal direction and 2000mm apart in the transverse direction.

[0035] In some specific implementation methods, refer to Figure 1 , Figure 2 and Figure 6The purlin 1 is a U-shaped metal profile with bent edges 11 on both sides of the groove, which facilitates clamping and fixing the photovoltaic module to the purlin. As an example, the purlin 1 is made of steel with a cross-sectional specification of U42*41*1.8mm.

[0036] As an example, such as Figure 1 and Figure 2 As shown, two purlins are distributed parallel to each other along the longitudinal direction on the same inclined plane, and the purlins extend laterally. Specifically, as... Figure 9 As shown, purlin 1 is made of multiple sections of metal profile spliced ​​together, and adjacent sections of metal profile are spliced ​​to bolt and nut assembly 7 by overlapping joint 6. As an example, bolt and nut assembly includes one M10*30 socket head cap bolt and one nut, and is equipped with two flat washers and one spring washer.

[0037] In some implementations, reference Figures 1-3 and Figure 10 Each support pier 5 has a J-type anchor bolt 51 pre-embedded and fixed at its top. The corner connection assembly 4 includes two angle steel adapters 41 connected in opposite directions. Each angle steel adapter 41 includes a first fixing plate 411 and a second fixing plate 412 connected vertically. Both the first fixing plate 411 and the second fixing plate 412 have slotted holes 413. The first fixing plates 411 of the two angle steel adapters 41 are connected by a first locking assembly 42. The second fixing plate 412 of the upper angle steel adapter 41 is connected to the lower part of the purlin 1 by a second locking assembly 43. The second fixing plate 412 of the lower angle steel adapter 41 is connected to the bolt head of the J-type anchor bolt 51 by a fastening assembly 44. Thus, since both angle steel adapters have slotted holes, the first locking assembly can act as a pivot and lock for easy rotation adjustment and fixation. During installation, the lower angle steel adapter and the J-type anchor bolts on the support pier are first fixed using the fastening assembly. Then, the two angle steel adapters are assembled using the first locking assembly. The upper angle steel adapter is adjusted to a suitable tilt angle according to the subsequent installation angle of the photovoltaic modules and then locked. Afterwards, the purlin is fixed to the upper angle steel adapter using the second locking assembly, thus achieving the installation and fixation of the purlin to the lower support pier via the corner connection assembly. For example, the J-type anchor bolts are M10-J type pre-embedded bolts with a height of 200mm and a thread length of 50mm. The angle steel adapter has a side length of 63mm, a thickness of 4mm, and a length of 60mm. The strip hole 413 is a 11*25mm oblong hole.

[0038] In some specific implementation methods, such as Figure 3As shown, the fastening assembly 44 includes a nut, a flat washer, and a spring washer. By tightening the fastening assembly, one of the lower angle steel adapters 41 in the corner connection assembly 4 can be secured.

[0039] In some specific implementation methods, such as Figure 3 As shown, both the first locking assembly 42 and the second locking assembly 43 include bolts, each equipped with a nut, a flat washer, and a spring washer. For example, the first locking assembly 42 includes an M8*30 hex bolt, equipped with two flat washers, one spring washer, and one nut; the second locking assembly 43 includes an M8*30 hex bolt, equipped with one flat washer, one spring washer, and one nut.

[0040] In some implementations, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the clamping assembly 3 includes a clamping block 31 and a third locking assembly 32. The clamping block 31 and the purlin 1 together clamp the photovoltaic module 2. The clamping block 31 is connected to the upper part of the purlin 1 through the third locking assembly 32.

[0041] In some specific implementation methods, such as Figure 4 and Figure 5 As shown, the third locking assembly 32 includes a bolt, which is equipped with a nut, a flat washer, and a spring washer. Specifically, as an example, the bolt is an M8*40 hexagonal stainless steel bolt, and the nut is a plastic wing nut.

[0042] In some specific implementation methods, such as Figure 7 and Figure 8 As shown, the clamping bracket 31 includes an edge clamping bracket 311 and a middle clamping bracket 312. The middle clamping bracket 312 includes two symmetrically distributed barbs 3121 and a connecting plate 3122 with bolt holes at the lower part of the two barbs 3121. The edge clamping bracket 311 includes one barb 3121 and a connecting plate 3122 with bolt holes at the lower part of the barb 3121. Thus, the edge clamping brackets and purlins can be used to clamp and fix the edges of the photovoltaic modules on the side span, and the middle clamping brackets and purlins can be used to clamp and fix the edges of two adjacent photovoltaic modules in the middle span.

[0043] Specifically, as an example, both the edge pressure code 311 and the middle pressure code 312 are aluminum alloy components with a length of 50mm.

[0044] In some specific implementation methods, such as Figure 1 and Figure 2As shown in the example, photovoltaic module 2 has a length of 2465mm in the longitudinal direction and a width of 1134mm in the transverse direction. The photovoltaic modules 2 are spliced ​​together at 20mm intervals in the transverse direction.

[0045] In some specific implementations, as examples, such as Figure 1 As shown, the angle between the inclined plane and the horizontal plane is 5 degrees.

[0046] The above embodiments are merely illustrative of the concept and technical solution of this utility model, and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
