Description

Technical Field

[0001] This utility model relates to the field of photovoltaic flexible support technology, specifically a quadrilateral cross tie rod support flexible support system. Background Technology

[0002] With the annual increase in domestic photovoltaic (PV) installations, land resources available for the construction of traditional PV power plants are becoming increasingly scarce. Against this backdrop, flexible PV support systems, as a new type of PV support structure, are receiving increasing attention from the industry. Compared to traditional PV support structures, flexible PV support systems offer advantages such as high headroom, large spans, and fewer pile foundations, making them well-suited for special environments such as fishponds, sewage treatment plants, and complex mountainous terrain.

[0003] Because flexible photovoltaic (PV) supports provide the rigidity of the entire system through prestressing, they are considered flexible systems. Compared to traditional PV supports, flexible PV supports are more sensitive to wind. They are prone to excessive vertical vibration and torsion, lateral overturning, and instability in the longitudinal direction.

[0004] To address the aforementioned technical deficiencies, this application proposes a flexible photovoltaic support system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quadrilateral cross-bracing flexible support system to solve the problems of excessive vertical amplitude and torsion and overturning instability in the longitudinal direction.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A quadrilateral cross-bracing flexible support system includes two sets of side beams and several sets of middle beams positioned between the two sets of side beams. The side beams and middle beams are welded to their respective pile foundations. Two or more rows of parallel photovoltaic arrays are installed on the side beams and middle beams. Each adjacent pair of pile foundations constitutes a span, and each row of photovoltaic arrays has more than two spans. The photovoltaic array includes a front main cable, a rear main cable, a cable-stayed system, a vertical wind-resistant system, and a longitudinal wind-resistant system. The two ends of the front and rear main cables are anchored to the two sets of side beams, and the front and rear main cables pass through the middle beams, which support them. The cable-stayed system is arranged outside the side beams, with its upper end connected to the side beams and its lower end connected to the foundation. The vertical wind-resistant system includes load-bearing cables with upward curvature and stabilizing cables with downward curvature. The system includes a cable, a stabilizing cable, a fixing clamp, and a tripod. The load-bearing cable is a continuous steel strand, with both ends anchored to the side beams. After connecting to the lower ends of multiple tripods between each span, the load-bearing cable passes through the top of the central beam, forming an upward-curving wave shape. Each span of the stabilizing cable is independent, with both ends connected to two adjacent pile foundations via stabilizing cable fixing clamps. The middle of the stabilizing cable connects sequentially to the bottom and top of multiple tripods between each span, forming a downward-curving wave shape. The front and rear main cables are connected to the upper sides of the tripods. The longitudinal wind-resistant system includes an upper connecting rod, a lower connecting rod, a tie rod one, a tie rod two, and a tie rod connector. The upper and lower connecting rods connect adjacent tripods in each row. Tie rod one and tie rod two intersect each other and are connected to two adjacent rows of tripods via tie rod connectors.

[0008] Preferably, the cable-stayed system is arranged on the outside of the two sets of side beams. The cable-stayed system includes a U-shaped connector, a connecting plate, a cable tie rod, a cable tie support, and side anchor piles. The side anchor piles are fixed to the foundation, the cable tie support is fixedly connected to the side anchor piles, and the upper U-shaped connector is connected to the side beam.

[0009] Preferably, the tripod includes a front support, a rear support, a diagonal brace, and an L-shaped connector. The two ends of the diagonal brace are connected to the front main cable and the rear main cable, respectively, and the L-shaped connector is connected to the load-bearing cable.

[0010] Preferably, the spacing between the tripods in each span is 5-10m.

[0011] Preferably, the upper connecting rod and the lower connecting rod have cross-sections of C-shaped steel, U-shaped steel, or round tubes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) Stabilizing cables can reduce the upward amplitude of the flexible support system under wind suction, while load-bearing cables can reduce the downward amplitude of the flexible support under wind pressure. The stabilizing cables and load-bearing cables work together to ensure the vertical safety of the flexible support in windy weather.

[0014] (2) The upper connecting rod, lower connecting rod, tie rod one, tie rod two, and front and rear supports work together to form a stable quadrilateral system, which mutually restrains the amplitude of adjacent rows in the longitudinal direction, thereby effectively avoiding the risks of large oscillations, torsion and overturning in the longitudinal direction of the flexible support system.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figures 1-10 A quadrilateral cross-bracing flexible support system includes two sets of side beams 1 and several sets of middle beams 2 arranged between the two sets of side beams 1. Each row of photovoltaic arrays has a pile foundation (i.e., side pile 3) under each of the left and right ends of the side beams 1, and the side beams 1 are welded to the side piles 3. Each middle beam 2 also has a pile foundation (i.e., middle pile 4) under it, and the middle beams 2 are welded to the middle piles 4. Two or more rows of parallel photovoltaic arrays are installed on the side beams 1 and middle beams 2. Each pair of adjacent pile foundations constitutes one span, that is, one span between a side beam 1 and a middle beam 2, and one span between adjacent middle beams 2. Each row of photovoltaic arrays has more than two spans.

[0040] Each row of photovoltaic arrays includes a front main cable 5, a rear main cable 6, a cable-stayed system, a vertical wind-resistant system, and a longitudinal wind-resistant system.

[0041] The front main cable 5 and the rear main cable 6 are anchored at both ends to the two sets of side beams 1. The front and rear ends of the middle beam are provided with through holes. The front main cable 5 and the rear main cable 6 pass through the through holes at both ends of the middle beam, and the front main cable 5 and the rear main cable 6 are also connected to the middle beam by U-bolts. The middle beam 2 can support the front main cable 5 and the rear main cable 6.

[0042] The cable-stayed system is arranged on the outside of the two sets of side beams 1. The cable-stayed system includes U-shaped connectors 7, connecting plates 8, cable rods 9, cable-stayed supports 10 and side anchor piles 11. There are two U-shaped connectors 7. The cable-stayed supports 10, the lower U-shaped connectors 7, the cable rods 9, and the upper U-shaped connectors 7 are connected in sequence. The side anchor piles 11 are fixed on the foundation. The cable-stayed supports 10 are fixedly connected to the side anchor piles 11. The upper U-shaped connectors 7 are connected to the side beams 1.

[0043] The vertical wind-resistant system includes upward-curved load-bearing cables 12, downward-curved stabilizing cables 13, stabilizing cable fixing clamps 14, and tripods. Multiple sets of tripods are installed between each span, with a spacing of 5-10m between each span, depending on the installation site conditions. Furthermore, the height of the tripods between each span gradually increases from both sides towards the middle. Each tripod includes a front support 15, a rear support 16, diagonal braces 17, and L-shaped connectors 18. The front support 15, rear support 16, and diagonal braces 17 are connected end-to-end, with the diagonal braces 17 located at the top. The L-shaped connectors 18 connect to the lower end of the tripod. The front main cable 5 and rear main cable 6 are connected to both ends of the diagonal brace 17 via U-bolts, ensuring that the height of the front main cable 5 is greater than the height of the rear main cable 6. Photovoltaic panels are installed on the front main cable 5 and rear main cable 6.

[0044] The load-bearing cable 12 is a continuous steel strand, with both ends anchored to the side beam 1. After being connected to the L-shaped connectors 18 at the lower end of multiple sets of triangular frames between each span, the load-bearing cable 12 passes through the top of the middle beam 2, forming an upward-curving wave shape. The load-bearing cable 12 is connected to the top of the middle beam 2 by U-bolts. The stabilizing cable 13 is independent for each span, with both ends connected to the adjacent two sets of pile foundations by stabilizing cable fixing clamps 14. The middle part of the stabilizing cable 13 is connected to the bottom and top of multiple sets of triangular frames between each span in sequence, forming a downward-curving wave shape. Specifically, the middle part of the stabilizing cable 13 is first connected to the L-shaped connector 18 of the first triangular frame, then to the diagonal bar 17 of the middle triangular frame, and finally to the L-shaped connector 18 of the tail triangular frame. The height of the first triangular frame is equal to the height of the tail triangular frame, and the height of the first and tail triangular frames is less than the height of the middle triangular frame.

[0045] The stabilizing cable 13 reduces the upward amplitude of the flexible support system under wind suction, while the load-bearing cable 12 reduces the downward amplitude of the flexible support under wind pressure. The stabilizing cable 13 and the load-bearing cable 12 work together to ensure the vertical safety of the flexible support system during windy weather.

[0046] The longitudinal wind-resistant system includes an upper connecting rod 19, a lower connecting rod 20, a first tie rod 21, a second tie rod 22, and a tie rod connector 23. The upper connecting rod 19 and the lower connecting rod 20 connect adjacent tripods in each row (front-back direction) into a single unit. The first tie rod 21 and the second tie rod 22 intersect each other and connect to the two adjacent rows of tripods via the tie rod connector 23. The cross-section of the upper connecting rod 19 and the lower connecting rod 20 is one of C-shaped steel, U-shaped steel, or round tubing.

[0047] The upper connecting rod 19, lower connecting rod 20, tie rod one 21, tie rod two 22, together with the front support 15 and the rear support 16, work together to form a stable quadrilateral system, which mutually restrains the amplitude of adjacent rows in the longitudinal direction, thereby effectively avoiding the risks of large oscillations, torsion and overturning in the longitudinal direction of the flexible support system.
