Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to an array-type photovoltaic module mounting bracket. Background Technology

[0002] To maximize land utilization, array-style photovoltaic panels are often densely packed, resulting in narrow gaps between them. This makes it difficult for cleaning equipment to access the panels, and manual cleaning is prone to oversights, leading to low cleaning efficiency. To address this issue, a cowshed-shaped photovoltaic support system has been introduced. By mimicking the structure of a cowshed, it increases the space available for photovoltaic panel installation to some extent.

[0003] However, the shed-shaped photovoltaic support system has many drawbacks in practical applications. From a cleaning perspective, while the arc or sloping structure at the top provides some drainage, it hinders the smooth operation of cleaning equipment. An improperly designed sloping angle can also cause wastewater backflow during cleaning, resulting in secondary contamination of the cleaned area.

[0004] The support columns of the shed-shaped bracket are densely distributed and irregularly positioned, which can obstruct the cleaning path. When cleaning equipment is working on large photovoltaic panels, it needs to frequently avoid the support columns, which not only prolongs the cleaning time but may also cause some photovoltaic panels to be missed during the avoidance process, making it impossible to achieve a complete cleaning. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the arc or inclined structure of the cowshed-shaped photovoltaic bracket hinders the smooth operation of the cleaning equipment, easily causes sewage backflow, and the dense and irregular distribution of the support columns obstructs the cleaning path.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an array-type photovoltaic module mounting bracket, including vertically arranged prefabricated pipe piles, steel columns vertically fixed to the top of the prefabricated pipe piles, and a steel truss structure inclinedly fixed between the steel columns. Purlins are arranged horizontally and vertically on the top of the steel truss structure. The purlins are equidistantly distributed along the length direction of the steel truss structure. A mounting plate for installing photovoltaic panels is provided on the top of the purlins. A drainage structure for supporting the ends of the photovoltaic panels is provided on the mounting plate.

[0007] Preferably, the steel truss structure is an inclined parallelogram structure, the steel truss structure includes a lower chord and an upper chord respectively set at the bottom and top, and straight web members are vertically fixedly connected between the lower chord and the upper chord. The straight web members are equidistantly arranged along the length direction of the steel truss structure, and diagonal web members are connected between adjacent straight web members.

[0008] Preferably, the straight web member is coaxially fixedly connected to the top of the steel column.

[0009] Preferably, diagonal bracing members are fixedly installed on both sides of the steel column below the top of the steel truss structure, and the top of the diagonal bracing members is fixedly connected to the lower chord.

[0010] Preferably, the bottom end of the steel column is provided with a base, the outer diameter of the base is larger than the outer diameter of the steel column, and a stiffening plate is connected between the base and the outer side wall of the steel column, the stiffening plate being evenly distributed around the axis of the steel column.

[0011] Preferably, the purlin has a right-angled trapezoidal cross-section, and a Z-shaped pull plate is connected to the purlin. The top end of the pull plate is fixedly connected to the top of the purlin, the bottom end of the pull plate is fixedly connected to one side of the purlin, and the middle part of the pull plate is in contact with the side wall of the purlin.

[0012] Preferably, a ridge plate is connected between the mounting plates located on both sides of the mounting bracket, and the bottom surfaces at both ends of the ridge plate are respectively attached to the top surfaces of the two mounting plates.

[0013] Preferably, the drainage structure includes drainage channels that are fitted onto the mounting plate. The drainage channels are perpendicular to the purlins and are evenly distributed. The photovoltaic panels overlap between two adjacent drainage channels. A partition is provided between the drainage channels and the photovoltaic panels. A U-shaped latch is bolted to the partition. The latch is located between adjacent photovoltaic panels. The top of the latch has a protruding structure for fastening the photovoltaic panels. Strip-shaped holes are evenly distributed on the partition.

[0014] Preferably, a spacer is fixedly provided between adjacent latches, and the spacer covers the gap between the photovoltaic panel and the spacer.

[0015] This utility model provides an array-type photovoltaic module mounting bracket, which has the following beneficial effects.

[0016] 1. The horizontally and vertically arranged purlins and mounting plates at the top of the steel truss structure allow for horizontal or reasonably angled installation of photovoltaic panels, avoiding obstruction of cleaning equipment by the curved structure and ensuring stable operation of the cleaning equipment. The drainage structure effectively guides wastewater discharge, preventing backflow and secondary pollution during cleaning. Simultaneously, the regular layout of prefabricated pipe piles, steel columns, and other supporting structures reduces obstruction of the cleaning path, eliminating the need for frequent detours by cleaning equipment, reducing the risk of omissions, and achieving comprehensive cleaning of photovoltaic panels. Furthermore, the drainage channels quickly drain rainwater or cleaning wastewater, preventing water accumulation and corrosion of the photovoltaic panels and supports. The design of the ridge plate and spacers prevents rainwater from seeping into the installation gaps, protecting the internal structure of the photovoltaic panels and supports, and extending their service life.

[0017] 2. The steel truss structure is an inclined parallelogram, forming a stable load-bearing system through the combination of lower chord, upper chord, straight web members, and diagonal web members, effectively distributing the weight of the photovoltaic panels and external loads. The steel columns are firmly connected to the precast pipe piles, and the diagonal bracing at the top further strengthens the connection between the steel truss structure and the steel columns, improving overall wind resistance and deformation resistance. The design of the base and stiffening plates increases the contact area with the foundation, enhancing the overall stability of the support structure. Attached Figure Description

[0023] like Figure 1-3 As shown, this utility model provides an array-type photovoltaic module mounting bracket, including vertically arranged prefabricated pipe piles 1, steel columns 2 vertically fixed to the top of the prefabricated pipe piles 1, and a steel truss structure inclinedly fixed between the steel columns 2. Purlins 8 are arranged horizontally and vertically on the top of the steel truss structure. The purlins 8 are equidistantly distributed along the length direction of the steel truss structure. A mounting plate 9 for mounting photovoltaic panels 13 is provided on the top of the purlins 8. A drainage structure for supporting the ends of the photovoltaic panels 13 is provided on the mounting plate 9.

[0024] The precast pipe piles 1 are made of C80 concrete. Steel columns 2 directly support the steel truss structure. The steel truss structure, together with purlins 8 and mounting plates 9, forms a roof-like structure. The steel truss structure is inclined. Steel columns 2 provide vertical support and a stable installation foundation for the steel truss structure. The steel truss structure bears the load of the photovoltaic panels 13 and the superstructure, distributing the load to the steel columns 2. Purlins 8 bear the load of the photovoltaic panels and the superstructure, distributing the load to the steel columns. Mounting plates 9 provide an installation surface for the photovoltaic panels 13 and simultaneously transfer the load of the photovoltaic panels 13 to the purlins 8. The drainage structure supports the ends of the photovoltaic panels 13 while guiding rainwater or clean wastewater out, preventing water accumulation and corrosion of the mounting plates 13.

[0025] like Figure 1 As shown. The steel truss structure is an inclined parallelogram structure. The steel truss structure includes a lower chord 3 and an upper chord 4 respectively set at the bottom and top. Straight web members 5 are vertically fixedly connected between the lower chord 3 and the upper chord 4. The straight web members 5 are equidistantly arranged along the length direction of the steel truss structure, and diagonal web members 6 are connected between adjacent straight web members 5. The inclined parallelogram structure of the steel truss structure adapts to the optimal light-receiving angle of the photovoltaic panel 13 through the inclined design, thereby improving power generation efficiency. The lower chord 3 and the upper chord 4 serve as the main load-bearing components of the steel truss, bearing longitudinal tension and compression. The straight web members 5 connect the upper and lower chords, enhancing the vertical stiffness of the steel truss and distributing the load. The diagonal web members 6 cooperate with the straight web members 5 to form a triangular stable structure, improving the deformation resistance of the steel truss.

[0026] like Figure 1 As shown, the straight web member 5 is coaxially fixedly connected to the top of the steel column 2. This ensures a stable connection between the steel column 2 and the steel truss structure, guaranteeing a smooth transfer of load from the steel truss to the steel column 2.

[0027] like Figure 1 As shown, inclined braces 7 are fixedly installed on both sides of the steel column 2 below the top of the steel truss structure, and the top of the inclined braces 7 is fixedly connected to the lower chord 3. The installation of the inclined braces 7 enhances the stability of the connection between the steel column 2 and the steel truss structure, resists the horizontal thrust generated by the steel truss structure, and prevents the steel column 2 from tilting; the connection between the inclined braces 7 and the steel truss directly applies the supporting force of the inclined braces 7 to the stress-bearing parts of the steel truss, improving the shear resistance of the overall structure.

[0028] As a preferred embodiment of this utility model, a base is provided at the bottom end of the steel column 2. The outer diameter of the base is larger than the outer diameter of the steel column 2. A stiffening plate is connected between the base and the outer side wall of the steel column 2, and the stiffening plate is evenly distributed around the axis of the steel column 2. The base increases the contact area between the steel column 2 and the precast pipe pile 1, allowing the load of the steel column 2 to be transferred to the precast pipe pile 1 more evenly. The stiffening plate strengthens the connection between the base and the steel column 2, preventing damage to the connection between the base and the steel column 2 due to excessive stress.

[0029] like Figure 1 As shown. The purlin 8 has a right-angled trapezoidal cross-section. A Z-shaped tie plate is connected to the purlin 8. The top end of the tie plate is fixedly connected to the top of the purlin 8, the bottom end of the tie plate is fixedly connected to one side of the purlin 8, and the middle part of the tie plate is in contact with the side wall of the purlin 8. Setting the cross-section of the purlin 8 into a right-angled trapezoidal structure enhances the bending stiffness of the purlin 8 and improves its load-bearing capacity. The tie plate is used to enhance the connection stability between the purlin 8 and the mounting plate 9 or other components, preventing lateral displacement of the purlin 8 under stress.

[0030] like Figure 1 As shown, a ridge plate 10 is connected between the mounting plates 9 located on both sides of the mounting bracket. The bottom surfaces of both ends of the ridge plate 10 are respectively attached to the top surfaces of the two mounting plates 9. The ridge plate 10 covers the gap between the mounting plates 9 to prevent the supporting structure below the mounting plates 9 from being eroded by rainwater.

[0031] like Figure 2 and Figure 3 As shown. The drainage structure includes drainage channels 11 that are fitted onto the mounting plate 9. The drainage channels 11 are perpendicular to the purlins 8 and are equidistantly distributed. The photovoltaic panel 13 overlaps between two adjacent drainage channels 11. A partition 12 is provided between the drainage channel 11 and the photovoltaic panel 13. A U-shaped latch 14 is bolted to the partition 12. The latch 14 is located between adjacent photovoltaic panels 13. The top of the latch 14 has a protruding structure to hold the photovoltaic panel 13 in place. The partition 12 has equidistant slotted holes 15. The drainage channels 11 are used to collect and drain rainwater or wastewater from the surface of the photovoltaic panel 13 to prevent water from overflowing. The output end of the drainage channel 11 is connected to an overflow trough to drain rainwater. The latches 14 are used to firmly fix the photovoltaic panel 13 in the installation position to prevent the photovoltaic panel 13 from shifting or falling off under the action of wind or other external forces. The slotted holes 15 are used to drain water above the partition 12 into the drainage channels 11.

[0032] like Figure 3 As shown. A spacer 16 is fixedly provided between adjacent latches 14, and the spacer 16 covers the gap between the photovoltaic panel 13 and the partition 12. The spacer 16 fills the gap between the photovoltaic panel 13 and the partition 12 to prevent rainwater from entering the gap.
