Description

Technical Field

[0001] This utility model relates to photovoltaic brackets, specifically to a tripod wind-resistant structure for flexible photovoltaic brackets. Background Technology

[0002] With the rapid development of photovoltaic power plants in recent years, higher requirements have been placed on the adaptability and maintainability of photovoltaic brackets. Existing flexible photovoltaic bracket wind-resistant systems have insufficient torsional stiffness, making them prone to irregular wind-induced vibration under wind loads, leading to microcracks in the modules. Furthermore, the current installation of flexible photovoltaic bracket wind-resistant structures often requires extensive on-site welding or fastening, increasing construction difficulty and cost. Uncontrollable on-site welding quality can also result in uneven strength of the bracket structure, affecting wind resistance performance. Therefore, there is an urgent need for a triangular wind-resistant structure for flexible photovoltaic brackets to address these problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a triangular wind-resistant structure for flexible photovoltaic support, so as to solve the problems mentioned in the background technology. This utility model has a reasonable structure, strong spatial rigidity, is easy to assemble and has excellent wind resistance performance.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a tripod wind-resistant structure for flexible photovoltaic brackets, comprising: a tripod;

[0005] The tripod includes an upper horizontal bar of angle steel, a pair of angle steel diagonal bars symmetrically arranged on the side wall of the upper horizontal bar of angle steel, a lower horizontal bar of angle steel between the end side walls of the pair of angle steel diagonal bars, a middle horizontal bar of angle steel placed between the side walls of the pair of angle steel diagonal bars and the upper horizontal bar of angle steel, and an angle steel vertical bar between the end side wall of the upper horizontal bar of angle steel and the end side wall of the middle horizontal bar of angle steel. The pair of angle steel diagonal bars and the upper horizontal bar of angle steel are arranged in a triangle.

[0006] At least two tripods are provided. A steel wire rope is installed between the lower crossbar of the angle steel on one of the adjacent tripods and the upper crossbar of the angle steel on the other adjacent tripod.

[0007] Furthermore, a second through hole is provided at the top of the lower crossbar of the angle steel on one of the adjacent tripods, and a suspension through hole is provided at the top of the upper crossbar of the angle steel on the other adjacent tripod. The wire rope is placed inside the second through hole and the suspension through hole.

[0008] Furthermore, fastening bolts are installed between the upper crossbar of the angle steel and a pair of diagonal angle steel members, between the pair of diagonal angle steel members and the lower crossbar of the angle steel, between the pair of diagonal angle steel members and the middle crossbar of the angle steel, between the upper crossbar of the angle steel and the vertical angle steel, between the vertical angle steel and the middle crossbar of the angle steel, and between the C-shaped support rod between rows and the upper crossbar of the angle steel on one of the adjacent tripods and the middle crossbar of the angle steel on the other adjacent tripod. Fastening nuts are installed on the fastening bolts. Multiple adjustment holes matching the fastening bolts are opened on the upper crossbar, middle crossbar, lower crossbar, diagonal angle steel, vertical angle steel, and C-shaped support rod between rows.

[0009] Furthermore, a pair of first rope clips are symmetrically arranged at the top of the upper crossbar of the angle steel, and a component cable passes through the interior of each pair of first rope clips longitudinally.

[0012] The installation components include U-bolts that pass through the upper or lower crossbar of the angle steel, with locking nuts on the U-bolts, and the U-bolts are connected to the first or second rope clamps.

Detailed Implementation

[0025] like Figure 1 As shown, this utility model provides a technical solution: a tripod wind-resistant structure for flexible photovoltaic brackets, comprising: a tripod;

[0026] The tripod includes an upper horizontal bar 1 made of angle steel, a pair of diagonal angle steel bars 2 symmetrically arranged on the side wall of the upper horizontal bar 1, a lower horizontal bar 4 made of angle steel between the end side walls of the pair of diagonal angle steel bars 2, a middle horizontal bar 3 made of angle steel between the upper horizontal bar 1 and the lower horizontal bar 4 made of angle steel between the side walls of the pair of diagonal angle steel bars 2, and a vertical bar 10 made of angle steel between the end side wall of the upper horizontal bar 1 and the end side wall of the middle horizontal bar 3. The pair of diagonal angle steel bars 2 and the upper horizontal bar 1 are arranged in a triangle.

[0027] At least two tripods are provided. A steel wire rope 5 is installed between the lower crossbar 4 of the angle steel on one adjacent tripod and the upper crossbar 1 of the angle steel on the other adjacent tripod. A row of C-shaped struts 13 is installed between the upper crossbar 1 of the angle steel on one adjacent tripod and the middle crossbar 3 of the angle steel on the other adjacent tripod. This design uses a planar triangular stable structure for the tripods. The tripods are reliably cross-connected by the row of C-shaped struts 13 and the steel wire rope 5. It combines rigidity and flexibility, and adopts flexible connection technology to replace the traditional rigid connection. It allows the tripods to produce a certain degree of micro-movement under wind vibration, thereby absorbing wind vibration energy, reducing the impact on photovoltaic modules, reducing the risk of module micro-cracks, and greatly enhancing the overall spatial rigidity and wind resistance performance during use.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The lower crossbar 4 of the angle steel on one of the adjacent tripods has a second through hole 42 at the top, and the upper crossbar 1 of the angle steel on the other adjacent tripod has a suspension through hole 103 at the top. The wire rope 5 is placed inside the second through hole 42 and the suspension through hole 103. This design makes it easy to suspend the wire rope 5 between the adjacent tripods by using the suspension through hole 103 and the second through hole 42, which facilitates the installation operation.

[0029] Reference Figure 2 , Figure 3 and Figure 6Fastening bolts 9 are installed between the upper horizontal bar 1 and a pair of angle steel diagonal bars 2, between the pair of angle steel diagonal bars 2 and the lower horizontal bar 4, between the pair of angle steel diagonal bars 2 and the middle horizontal bar 3, between the upper horizontal bar 1 and the vertical bar 10, between the vertical bar 10 and the middle horizontal bar 3, and between the C-shaped support rod 13 between rows and the upper horizontal bar 1 of one adjacent tripod and the middle horizontal bar 3 of the other adjacent tripod. Fastening bolts 9 are fitted with fastening nuts. Multiple adjusting holes 12 matching the fastening bolts 9 are provided on the upper horizontal bar 1, middle horizontal bar 3, lower horizontal bar 4, diagonal bar 2, vertical bar 10, and C-shaped support rod 13 between rows. This design utilizes fastening bolts... Bolt 9 passes through adjustment hole 12 and is tightened with fastening nut, facilitating rapid on-site assembly of the upper crossbar 1, a pair of diagonal crossbars 2, middle crossbar 3, lower crossbar 4, and vertical crossbar 10 of angle steel. This greatly reduces on-site welding work, shortens the construction cycle, and avoids material waste caused by material errors, resulting in high economic efficiency. The upper crossbar 1, a pair of diagonal crossbars 2, middle crossbar 3, lower crossbar 4, and vertical crossbar 10 of angle steel, as well as the C-shaped struts 13 between rows, can all be produced and processed in a standardized factory, ensuring that the quality of each component and each weld is effectively guaranteed, the parts are dimensionally accurate, and the component strength is uniform, which can greatly improve the overall assembly effect and load-bearing performance of the tripod.

[0030] Reference Figure 2 and Figure 4 A pair of first rope clips 101 are symmetrically arranged at the top of the upper crossbar 1 of the angle steel. A component cable 11 is longitudinally passed through the inside of each pair of first rope clips 101. A second rope clip 6 is arranged at the center of the bottom of the lower crossbar 4 of the angle steel. A stabilizing cable 8 is longitudinally passed through the inside of the second rope clip 6.

[0031] Reference Figure 1 The first rope clamp 101 has a first rope hole 1011 for the component cable 11 to pass through, and the second rope clamp 6 has a second rope hole 61 for the stabilizing cable 8 to pass through, which improves the rationality of the design.

[0032] Reference Figure 1 and Figure 3 An installation assembly 102 is provided between the first rope clamp 101 and the upper crossbar 1 of the angle steel, and between the second rope clamp 6 and the lower crossbar 4 of the angle steel; each rope clamp consists of one U-bolt, a ram's horn base and two sets of nuts.

[0033] The mounting assembly 102 includes a U-bolt 1021 that passes through the upper crossbar 1 or the lower crossbar 4 of the angle steel. A locking nut 1022 is provided on the U-bolt 1021. The U-bolt 1021 is connected to the first rope clamp 101 or the second rope clamp 6. This design facilitates the installation and fixation of the first rope clamp 101 on the upper crossbar 1 and the second rope clamp 6 on the lower crossbar 4 of the angle steel by using the locking nut 1022 to connect with the U-bolt 1021 on the first rope clamp 101 or the U-bolt 1021 on the second rope clamp 6. Both the upper crossbar 1 and the lower crossbar 4 of the angle steel have through holes through which the U-bolt 1021 passes. Both the first rope clamp 101 and the second rope clamp 6 are provided with U-bolts 1021.

[0034] Reference Figure 2 The bottom of the angle steel lower crossbar 4 on one of the adjacent tripods and the bottom of the angle steel lower crossbar 4 on the other adjacent tripod are both provided with a first through hole 41. Wind-resistant cables 7 pass through the first through hole 41 and the second rope hole 61 in sequence.

[0035] According to an embodiment of this application, a set of triangular frames is formed by connecting an upper horizontal bar 1, a pair of diagonal angle bars 2, a middle horizontal bar 3, a lower horizontal bar 4, and a vertical angle bar 10 using fastening bolts 9. A set of triangular frames connects two component cables 11 and one stabilizing cable 8 together using three sets of rope clamps, forming a single-row spatial triangular pyramid shape. Multiple rows of spatial triangular pyramids are then connected into an overall photovoltaic array via steel wire ropes 5, wind-resistant cables 7, and the triangular frames, collectively resisting wind loads.

[0036] Reference Figures 1-6As an embodiment of this utility model: Workers use fastening bolts 9 through adjusting holes 12 and fastening nuts to facilitate the rapid on-site assembly of the upper crossbar 1, a pair of diagonal crossbars 2, the middle crossbar 3, the lower crossbar 4, and the vertical bar 10 of the angle steel into a tripod. Then, using fastening bolts 9 through adjusting holes 12 and fastening nuts, the C-shaped support rods 13 are connected and fixed to the upper crossbar 1 of one adjacent tripod and the middle crossbar 3 of the other adjacent tripod. Next, the locking nut 1022 is connected to the U-bolt 1021 on the first rope clip 101 or the U-bolt 1021 on the second rope clip 6, thus facilitating the installation and fixing of the first rope clip 101 to the upper crossbar 1 and the second rope clip 6 to the lower crossbar 4. The suspension through hole 10... 3. The steel wire rope 5 is suspended between adjacent tripods through the second through hole 42. Finally, the component cable 11 is longitudinally passed through the first rope hole 1011, the stabilizing cable 8 is longitudinally passed through the second rope hole 61, and the wind-resistant cable 7 is transversely passed through the first through hole 41 and the second rope hole 61 to stabilize the adjacent tripods. This facilitates installation, greatly reduces on-site welding work, shortens the construction cycle, and avoids material waste caused by material errors. It is very economical. Among them, the upper horizontal bar 1, a pair of diagonal bars 2, the middle horizontal bar 3, the lower horizontal bar 4, the vertical bar 10, and the C-shaped support bar 13 between rows can all be produced and processed in the factory in a standardized manner. This ensures that the quality of each component and each weld is effectively guaranteed, the part dimensions are accurate, the component strength is uniform, and the overall assembly effect and stress performance of the tripod are greatly improved.

[0037] The tripods utilize a planar triangular stabilizing structure, with reliable cross-connections between them via rows of C-shaped struts 13 and steel wire ropes 5. This combination of rigidity and flexibility, employing flexible connection technology instead of traditional rigid connections, allows the tripods to undergo a certain degree of micro-movement under wind vibration, thereby absorbing wind vibration energy, reducing the impact on photovoltaic modules, lowering the risk of micro-cracks in the modules, and greatly enhancing the overall spatial rigidity and wind resistance during use, thus improving the practicality of this invention.
