Description

Technical Field

[0001] This utility model relates to the technical field of truss-type intermediate beam structures, and in particular to a photovoltaic flexible support cable truss-type intermediate beam structure. Background Technology

[0002] With the development of photovoltaic construction, the application of flexible photovoltaic supports is gradually increasing, and the application scenarios are also becoming more diverse. At the same time, due to the scarcity of land resources, the amount of land available for photovoltaic construction is decreasing. Therefore, the issue of land utilization efficiency in photovoltaic construction has become a concern for photovoltaic builders.

[0003] Existing flexible photovoltaic (PV) support systems typically have two module cables running east-west, with PV panels arranged parallel to these cables. To prevent shading between rows, a certain distance must be maintained between each row of PV panels in the north-south direction. In the middle of the PV array, excluding the side beams, truss-type intermediate beams are placed at certain intervals in the east-west direction. These intermediate beams are supported by intermediate piles. Typically, two or three rows of modules share one truss-type intermediate beam in the north-south direction. To reduce the number of piles, each pair of truss-type intermediate beams usually shares an intermediate pile. Despite this, the number of intermediate piles still accounts for a large proportion of the entire PV system, resulting in high PV construction costs.

[0004] Therefore, for the existing flexible photovoltaic supports, the number of intermediate piles still accounts for a large proportion of the entire photovoltaic system, resulting in high photovoltaic construction costs. A flexible photovoltaic support cable truss intermediate beam structure can be designed. By optimizing the cable truss and connection relationship, increasing the span of the north-south truss intermediate beam, reducing the number of pile foundations, and lowering photovoltaic construction costs, the above problems can be easily solved.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1-5 As shown, a photovoltaic flexible support cable truss type intermediate beam structure includes a truss type intermediate beam 1, which includes two sets of cable truss side supports 101. The two sets of cable truss side supports 101 are arranged at intervals along the north-south direction. Side beams 2 for fixing the truss type intermediate beam 1 are provided at both the east and west ends of the truss type intermediate beam 1. Multiple sets of triangular trusses 3 that provide point support are evenly arranged between the truss type intermediate beam 1 and the side beams 2. Multiple sets of component cable mechanisms for connecting the truss type intermediate beam 1, the triangular trusses 3 and the side beams 2 are arranged along the north-south direction between the truss type intermediate beam 1, the triangular trusses 3 and the side beams 2.

[0024] The cable truss side support 101 includes two sets of side support crossbeams 1011, and two sets of support longitudinal beams are symmetrically arranged between the two sets of side support crossbeams 1011. The side support crossbeams 1011 and the side support longitudinal beams 1012 are connected end to end to form a quadrilateral frame. Four sets of side support side beams 1013 are evenly arranged at the upper end of the connection between the side support crossbeams 1011 and the side support longitudinal beams 1012. The bottom of the side support side beams 1013 is connected to the four vertices of the quadrilateral formed by the side support crossbeams 1011 and the side support longitudinal beams 1012. The tops of the four sets of side support side beams 1013 intersect at one point. The quadrilateral frame is formed by the connection between the side support crossbeams 1011 and the side support longitudinal beams 1012. The bottom of the side support side beams 1013 is connected to the four vertices of the quadrilateral, and the tops intersect at one point. This structure makes the cable truss side support 101 form a stable three-dimensional frame, which enhances the overall structural stability and wind and earthquake resistance.

[0025] The cable truss side support 101 also includes four sets of side support short cross braces 1016. These four sets of short cross braces 1016 are located above two sets of side support crossbeams 1011 and two sets of support longitudinal beams, respectively. Both ends of the four sets of side support crossbeams 1011 are connected to the four sets of side support side beams 1013. The four sets of side support short cross braces 1016 are matched with two sets of front diagonal braces 1014 and two sets of rear diagonal braces 1015. One end of the two sets of front diagonal braces 1014 is connected to the connection point between one end of the two sets of side support crossbeams 1011 and one of the two sets of side support side beams 1013. The other end of the two sets of front diagonal braces 1014... The end is connected to the connection point of one end of two sets of short cross braces 1016 of the side brackets and the side beams 1013 of the other two sets of side brackets. The two sets of rear diagonal braces 1015 of the side brackets and the two sets of front diagonal braces 1014 of the side brackets are set opposite to each other. Through the combination of the front diagonal braces 1014, the rear diagonal braces 1015 and the short cross braces 1016 of the side brackets, a triangular stable structure is formed, which enhances the bracket's ability to resist lateral and torsional forces, so that the bracket can remain stable in complex environments, ensure the long-term stable operation of the photovoltaic system, reduce maintenance costs caused by structural damage, and is more conducive to reducing the setting of intermediate piles and reducing construction costs.

[0026] Between the two sets of cable truss side supports 101, there are bottom left truss cable 102, bottom right truss cable 103, and top truss cable 104 respectively. The two ends of the bottom left truss cable 102 and bottom right truss cable 103 are respectively connected to the near ends of the side support longitudinal beams 1012 of the two sets of cable truss side supports 101. The two ends of the top truss cable 104 are respectively connected to the top of the two sets of cable truss side supports 101. The core force system of the truss-type intermediate beam 1 is constructed by the bottom left truss cable 102, bottom right truss cable 103, and top truss cable 104. It can effectively transfer and disperse the load generated by the photovoltaic module, distribute the force evenly to the entire structure, avoid excessive local stress, improve the load-bearing capacity of the structure, and enable the truss-type intermediate beam 1 to work normally under a larger span. It reduces the dependence on intermediate piles and reduces the number of pile foundations and construction costs.

[0027] Multiple sets of bottom support rods 105 are evenly arranged on the bottom left truss cable 102 and bottom right truss cable 103. A bottom diagonal support rod 108 is provided between every two sets of bottom support rods 105. The two ends of the bottom diagonal support rod 108 are diagonally connected to the ends of the two sets of bottom support rods 105. Multiple sets of left side support rods 107 and multiple sets of right side support rods 106 are matched at both ends of the multiple sets of bottom support rods 105. The upper ends of the left side support rods 107 and right side support rods 106 are fixedly connected, and the lower ends of the left side support rods 107 and right side support rods 106 are respectively connected to the two ends of the bottom support rods 105. The bottom diagonal support rods 108 connect the bottom support rods 105 to form a stable triangular structure. The left side support rods 107 and right side support rods 106 cooperate with each other to enhance the integrity and stability of the bottom structure, effectively improve the ability of the truss-type intermediate beam 1 to resist vertical and horizontal loads, provide strong support for increasing the span of the truss-type intermediate beam 1 and reducing the number of intermediate piles, and at the same time ensure the stable installation and operation of photovoltaic modules and reduce maintenance costs.

[0028] Multiple sets of left diagonal braces 110 are provided between multiple sets of left-side support rods 107. One end of the left diagonal brace 110 is connected to the bottom of the left-side support rod 107, and the other end of the left diagonal brace 110 is connected to the top of the adjacent left-side support rod 107. Multiple sets of right diagonal braces 109 are provided between multiple sets of right-side support rods 106. One end of the right diagonal brace 109 is connected to the bottom of the right-side support rod 106, and the other end of the right diagonal brace 109 is connected to the top of the adjacent right-side support rod 106. Through the cooperation of the left diagonal braces 110 and the right diagonal braces 109, the support structure on the side of the truss-type intermediate beam 1 is optimized, the rigidity and stability of the side are enhanced, the ability of the structure to resist wind loads and other horizontal forces is improved, and the safe operation of the photovoltaic system is ensured under severe weather conditions.

[0029] The component cable mechanism includes a high component cable 4, with a corresponding main load-bearing cable 6 on one side of the high component cable 4. The high component cable 4 and the main load-bearing cable 6 are connected to the top of the side beam 2, the triangular truss 3, and the truss-type intermediate beam 1, respectively. Below the high component cable 4, there is a low component cable 5, with a corresponding secondary load-bearing cable 7 on one side of the low component cable 5. The low component cable 5 and the secondary load-bearing cable 7 are connected to the bottom of the side beam 2, the triangular truss 3, and the truss-type intermediate beam 1, respectively. The high component cable 4 and the low component cable 5 provide a direct mounting carrier for the photovoltaic equipment. Through the combination of the two with the main load-bearing cable 6 and the secondary load-bearing cable 7, a layered load-bearing system is formed. The high component cable 4 and the main load-bearing cable 6 bear the main load, while the low component cable 5 and the secondary load-bearing cable 7 provide auxiliary load-bearing, which reasonably distributes the weight of the photovoltaic equipment and the external load, making the entire structure more evenly stressed.

[0030] Four sets of beam foundations 8 are provided below each of the two sets of cable truss side supports 101. The top of the four sets of beam foundations 8 is welded to the connection points of the two sets of side support crossbeams 1011 and the two sets of side support longitudinal beams 1012. The beam foundations 8 provide a stable foundation support for the truss-type intermediate beam 1, ensuring reliable force transmission between the truss-type intermediate beam 1 and the beam foundations 8. This allows the entire structure to stably bear the photovoltaic equipment and external loads after the photovoltaic equipment is installed, enhancing the integrity and stability of the structure, reducing the risk of structural damage caused by the instability of the beam foundations 8, helping to reduce the number of intermediate piles, reducing construction costs, and facilitating construction and installation, thus improving construction efficiency.

[0031] During the operation, firstly, side beams 2 are installed at appropriate positions at the east and west ends of the photovoltaic array. The side beams 2 are then firmly fixed to the foundation using embedded parts. Next, the truss-type intermediate beam 1 is assembled. Two sets of cable truss side supports 101 are installed at a distance of 50 meters between them in the north and south directions. They are connected to the ground through four sets of beam foundations 8. The beam foundations 8 are made of reinforced concrete to ensure their stability. The top of the beam foundation 8 is fixed to the side support crossbeam 1011 and side support longitudinal beam 1012 by welding to form a stable foundation support.

[0032] After the two sets of cable truss side supports 101 are installed, the bottom left truss cable 102, the bottom right truss cable 103 and the top truss cable 104 are installed in sequence, and their two ends are accurately connected to the cable truss side supports 101 respectively. Subsequently, multiple sets of bottom support rods 105, bottom diagonal support rods 108, left support rods 107, right support rods 106, left diagonal support rods 110, and right diagonal support rods 109 are installed to complete the bottom and side support structure of the truss-type intermediate beam 1. Next, a set of triangular trusses 3 is installed every 8 meters between the truss-type intermediate beam 1 and the side beam 2 to enhance the point support effect. Finally, the component cable mechanism is installed to connect the high component cable 4, the main load-bearing cable 6 to the side beam 2, the triangular trusses 3, and the top of the truss-type intermediate beam 1, and the low component cable 5, the secondary load-bearing cable 7 to the side beam 2, the triangular trusses 3, and the bottom of the truss-type intermediate beam 1, forming a complete photovoltaic flexible support cable truss-type intermediate beam 1 structure. Photovoltaic panels can then be installed on the high component cable 4 and the low component cable 5.

[0033] Its working principle is as follows: after the photovoltaic panels are installed and put into use, the various loads such as the photovoltaic panels' own weight, wind load, and snow load are first transferred to the main load-bearing cable 6 and the secondary load-bearing cable 7 through the high component cable 4 and the low component cable 5. Since the component cable mechanism forms a layered load-bearing system, the high component cable 4 and the main load-bearing cable 6 bear the main load, while the low component cable 5 and the secondary load-bearing cable 7 provide auxiliary load-bearing, so that the load can be reasonably distributed.

[0034] The main load-bearing cable 6 and the secondary load-bearing cable 7 further transfer the load to the truss-type intermediate beam 1 and the triangular truss 3. The bottom left truss cable 102, the bottom right truss cable 103, and the top truss cable 104 of the truss-type intermediate beam 1 form the core force-bearing system, which can effectively transfer and distribute the load. The stable triangular structure formed by the bottom diagonal brace 108, the left diagonal brace 110, and the right diagonal brace 109 evenly distributes the force to the entire structure, avoiding excessive local stress. The three-dimensional frame structure of the cable truss side support 101 and the triangular stable structure formed by the front diagonal brace 1014, the rear diagonal brace 1015, and the short horizontal brace 1016 of the side support enhance the ability to resist lateral forces, torsional forces, and vertical loads, so that the entire structure can stably transfer the load to the beam foundation 8, and finally from the beam foundation 8 to the ground, ensuring the stable operation of the photovoltaic system.

[0035] Its beneficial effects are significant. By combining the connection relationships between the truss-type intermediate beam 1, triangular truss 3, side beam 2, and component cable mechanism, the span of the north-south truss-type intermediate beam 1 is increased, and the number of intermediate piles is reduced. At the same time, combined with the stable and convenient installation method of the four sets of beam foundations 8 and the simplified construction process, the cost of intermediate pile materials and construction is reduced, thereby reducing the overall cost of photovoltaic construction. Through the three-dimensional frame structure of the cable truss side support 101, which consists of two sets of side support crossbeams 1011, two sets of support longitudinal beams, and four sets of side support side beams 1013, and the two sets of side support front diagonal braces 1014, two sets of side support rear diagonal braces 1015, and four sets of side support short The combination of the triangular stable structure formed by the horizontal bracing 1016 enhances the ability to resist lateral and torsional forces. Combined with the combination of the bottom and side triangular support structures consisting of multiple sets of bottom bracing rods 105, bottom diagonal bracing rods 108, left side bracing rods 107, right side bracing rods 106, left diagonal bracing rods 110 and right diagonal bracing rods 109, the ability to resist vertical and horizontal loads is improved, ensuring the stable operation of the photovoltaic system. By increasing the span of the truss-type intermediate beam 1 and optimizing the arrangement of photovoltaic panels on the high-module cable 4 and low-module cable 5, more photovoltaic panels can be arranged on the same land area, effectively improving land use efficiency and adapting to the current situation of scarce land resources.
