Description

Technical Field

[0001] This invention relates to the field of flexible photovoltaic support technology, and more specifically, to a flexible photovoltaic support with automatic orientation correction function. Background Technology

[0002] Flexible photovoltaic (PV) supports are a new type of PV support structure that uses prestressed steel cables instead of traditional rigid purlins. They can span ditches and slopes, adapting to scenarios such as fishponds and sewage treatment plants, with minimal disruption to the original terrain. Flexible PV supports offer advantages such as flexibility, sparse spacing, height, large span, tolerance for slight deformation, and reliance on prestressing for tension. Compared to traditional supports, they can save approximately 25% of land use and 20-30% of steel consumption, and their large span characteristics reduce the number of pile foundations, shortening the construction period.

[0003] Flexible photovoltaic (PV) support structures are mainly composed of steel cables and flexible PV panels. The flexible PV panels are rigidly fixed to the outer ends of the steel cables by clamps. Flexible PV support structures that cross mountains, riverbanks, and seas, as well as those with high wind pressure year-round, are subject to significant wind pressure. This wind pressure causes the steel cables to twist, and temperature differences also cause the steel cables to expand and contract, leading to deformation. The clamps have no space for buffering, yielding, or stress relief, so all the stress is concentrated on the clamps. As stress accumulates, it causes the clamps to deform and crack. This not only causes the flexible PV panels to detach from the steel cables but also causes the installation position of the flexible PV panels to shift, increasing the swaying amplitude of both the steel cables and the flexible PV panels.

[0004] Therefore, this application proposes a flexible photovoltaic support with automatic orientation correction function to solve the above problems. Summary of the Invention

[0015] A flexible hose is installed between the left and right air cylinders, and the two ends of the hose are respectively connected to the air inlet chamber and the air outlet chamber.

[0016] Air holes are provided on the outer sides of the left and right air cylinders, and the air holes are connected to the air outlet chamber.

[0017] In a new embodiment, a limiting ring is fixedly connected to the outer side of the connecting plate. The limiting ring is arc-shaped, and the connecting rod and the limiting ring are concentrically arranged.

[0030] In a new embodiment, sliding columns are symmetrically fixedly connected to the bottom of the subframe;

[0031] Two sliding columns are provided on each side, and the sliding columns are slidably connected to the A steel cable.

[0032] Beneficial effects: Compared with the prior art, the advantages of this invention are:

[0033] 1. When the top and bottom surfaces of the flexible photovoltaic panel are subjected to wind pressure, the two A-cables bend. During this process, the rotating rod rotates outside the connecting rod. At the same time, the limiting ring and clamping rod control the rotating rod to rotate within ±5°, preventing the two A-cables from always being taut. Meanwhile, the torque generated by the torsion spring controls the deformation range of the two A-cables, relieving the force on the A-cables and preventing them from breaking due to wind pressure exceeding the limit. It also prevents the flexible photovoltaic panel from shifting to the outside of the two A-cables due to bending. 2. When the side of the flexible photovoltaic panel is subjected to wind pressure, the distance between the two A-cables will increase or decrease due to wind pressure. At this time, the slide slides at the bottom of the bracket. Through the compression and release of the spring between the slide and the connecting column, the wind pressure on the side of the flexible photovoltaic panel is offset, allowing the distance between the two A-cables to change slightly. This prevents wind pressure from concentrating at the clamping position used to fix the flexible photovoltaic panel, thereby preventing the clamps from breaking or being damaged, which would cause the flexible photovoltaic panel to shift between the two A-cables. 3. When the sides of the central frame and the sub-frame are subjected to wind pressure, the carriage moves towards the connecting column along the direction of the wind pressure. The elastic force generated by the compression and release of the spring relieves the wind pressure and corrects the deviation. The spring has a limited buffering effect on the two A steel cables. When the left side of the central frame is subjected to wind pressure, the airflow enters the air inlet chamber of the left air cylinder. The airflow in the air inlet chamber enters the air outlet chamber of the right air cylinder through the hose. The airflow impacts the right air cylinder, causing it to generate a reverse thrust. The thrust of the left air cylinder under wind pressure and the thrust of the right air cylinder under airflow cancel each other out. Together with the spring, they improve the correction strength of the central frame and the sub-frame, improve the stability of the two A steel cables and the flexible photovoltaic panel at the top, reduce the deviation of the flexible photovoltaic panel, and realize the automatic correction of the flexible photovoltaic panel.

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] This application provides a flexible photovoltaic support with automatic orientation correction function, which solves the problem in the prior art where the flexible photovoltaic support is rigidly fixed to the outside of the steel cable by clamps. When the flexible photovoltaic panel is subjected to wind pressure, the stress generated by the wind pressure is concentrated at the clamp position. As the wind pressure stress continues to increase, the clamps break and slip, causing the flexible photovoltaic panel to shift to the outside of the steel cable.

[0055] Example 1: Please refer to Figures 1-7 A flexible photovoltaic support with automatic orientation correction function includes a connecting frame assembly 1 and a crossbar 2 installed on its outer side. An upward orientation correction mechanism 3 is symmetrically installed on the outer side of the crossbar 2.

[0056] The upward correction mechanism 3 includes a connecting plate 31 symmetrically fixedly connected to the outside of the crossbar 2. A connecting rod 32 is fixedly connected to the outside of the connecting plate 31. A rotating rod 33 is rotatably connected to the outside of the connecting rod 32. A torsion spring 34 is fixedly connected between the connecting rod 32 and the rotating rod 33. A steel cable 35 is installed on the outside of the rotating rod 33.

[0057] A central frame 4 is installed between two steel cables 35. Sub-frames 5 are installed on both sides of the central frame 4. Flexible photovoltaic panels are installed on the top of both the central frame 4 and the sub-frames 5.

[0058] Specifically, the working principle of the upward-facing correction mechanism 3 is as follows:

[0059] When the top and bottom surfaces of the flexible photovoltaic panel are subjected to wind pressure, the central frame 4 and the sub-frame 5 cause the two A steel cables 35 to bend longitudinally. The bent A steel cables 35 cause the rotating rod 33 mounted on the outside of the rotating rod 33 to rotate around the connecting rod 32 on the outside of the connecting plate 31. During this process, the torsion spring 34 generates torque. After the wind pressure decreases, the torsion spring 34 drives the rotating rod 33 to rotate and return to its original position. The torsion spring 34 prevents the bending amplitude of the A steel cables 35 from being too large and allows the A steel cables 35 to float within the rated range, avoiding the two A steel cables 35 from remaining taut for a long time under wind pressure. This prevents permanent deformation or even breakage of the A steel cable 35, and also avoids the stress generated by wind pressure on the flexible photovoltaic panel from concentrating at the sliding column 18 at the bottom of the subframe 5, preventing the sliding column 18 from bearing stress beyond the range, which would cause the sliding column 18 to break. This would cause the center frame 4 and the subframe 5 to shift between the two A steel cables 35. In addition, when crossing mountains or the sea, the temperature difference between day and night is large, which would also cause the A steel cable 35 to deform due to the temperature difference. The rotatable rotating rod 33 controls the deformation range of the A steel cable 35 when it stretches or shortens due to the temperature difference.

[0060] A side correction mechanism 6 is installed at the bottom of the center frame 4. The side correction mechanism 6 includes a bracket 61 symmetrically fixedly connected to the bottom of the center frame 4. A slide 62 is slidably connected to the outside of the bracket 61. A connecting column 63 is fixedly connected to the bottom of the center frame 4. Side rods 64 are fixedly connected to both sides of the connecting column 63. The side rods 64 and the slide 62 are slidably connected. A spring 65 is fixedly connected between the slide 62 and the connecting column 63.

[0061] A sleeve post 66 is installed on the outside of steel cable 35, and a diagonal bar 67 is rotatably connected between the slide 62 and the sleeve post 66.

[0062] Specifically, the working principle of the side correction mechanism 6 is as follows:

[0063] When the sides of the central frame 4 and the sub-frame 5 are subjected to wind pressure, the distance between the two A steel cables 35 changes due to the wind pressure. During this process, due to the change in the distance between the two A steel cables 35, the distance between the two sleeve posts 66 that connect the two A steel cables 35 increases or decreases. At this time, the included angle between the two diagonal rods 67 connected to the outside of the slide 62 increases or decreases. At the same time, the slide 62 slides at the position of the side rod 64 outside the connecting post 63. When the included angle between the two diagonal rods 67 increases, the spring 65 is compressed. When the included angle between the two diagonal rods 67 decreases, the spring 65 is extended. When the wind pressure decreases, the elastic force generated by the release of the spring 65 offsets part of the wind pressure, reduces the wind pressure on the two A steel cables 35, and prevents the wind pressure on one side of the central frame 4 and the sub-frame 5 from continuously accumulating, causing the central frame 4 and the sub-frame 5 to shift to one side of the two A steel cables 35.

[0064] Please see Figures 6-9 As a preferred embodiment of the present invention, an auxiliary center frame 4 and a sub-frame 5 are installed on the outer side of the carriage 62 to provide a pressure relief mechanism 7 for correction.

[0065] The four diagonal braces 67 are arranged in a diamond shape;

[0066] The four diagonal braces 67 arranged in a diamond shape can relieve pressure on the two sides of the central frame 4 and the sub-frame 5 respectively;

[0067] The pressure relief mechanism 7 includes a left air cylinder 71 and a right air cylinder 72, which are respectively fixedly connected to the outside of the two slides 62;

[0068] The interiors of the left air cylinder 71 and the right air cylinder 72 are divided into an air inlet chamber 73 and an air outlet chamber 74 by a partition. The air inlet end of the air inlet chamber 73 is funnel-shaped.

[0069] A flexible hose 75 is installed between the left air cylinder 71 and the right air cylinder 72, and the two ends of the flexible hose 75 are connected to the air inlet chamber 73 and the air outlet chamber 74, respectively.

[0070] Air holes 76 are provided on the outer sides of the left air cylinder 71 and the right air cylinder 72, and the air holes 76 are connected to the air outlet chamber 74;

[0071] Specifically, the working principle of the pressure relief mechanism 7 is as follows:

[0072] When the left side of the center frame 4 and the sub-frame 5 is subjected to wind pressure, the left slide 62 slides at the bracket 61 on the left side of the center frame 4, and the left spring 65 is in a compressed state. The release of the spring 65 generates a reverse force to offset part of the force generated by the wind pressure on the left side. At the same time, part of the airflow enters the air inlet chamber 73 inside the left air cylinder 71. The airflow enters the air outlet chamber 74 inside the right air cylinder 72 from the air inlet chamber 73 of the left air cylinder 71 along the output end of the hose 75. The airflow impacts the air outlet chamber 74 inside the right air cylinder 72 and generates a reverse force to the left. The reaction force pushes the right slide 62 to slide to the left at the bracket 61 on the right side of the bottom of the center frame 4. The left spring 65 is compressed and released to generate a left elastic force. The right force generated by the wind pressure on the left side and the left force of the airflow are mostly offset. In this process, together with the right elastic force generated by the release of the left spring 65, part of the wind pressure on the left side of the center frame 4 and the sub-frame 5 is offset.

[0073] When the right side of the central frame 4 and the sub-frame 5 is subjected to wind pressure, the right slide 62 slides at the bracket 61 on the right side of the central frame 4, and the right spring 65 is in a compressed state. The release of the spring 65 generates a reverse force to offset part of the force generated by the wind pressure on the right side. At the same time, part of the airflow enters the air inlet chamber 73 inside the right air cylinder 72. The airflow enters the air outlet chamber 74 inside the left air cylinder 71 from the air inlet chamber 73 of the right air cylinder 72 along the output end of the hose 75. The airflow impacts the air outlet chamber 74 inside the left air cylinder 71 and generates a reverse force to the right. The reaction force pushes the left slide 62 to slide to the right at the bracket 61 on the left side of the bottom of the central frame 4. The right spring 65 is compressed and released to generate a right elastic force. The force to the left generated by the wind pressure on the right side and the force to the right generated by the airflow are mostly offset. In this process, the release of the right spring 65 generates a left elastic force to offset part of the wind pressure on the right side of the central frame 4 and the sub-frame 5.

[0074] The two opposing forces cancel each other out and work together with the elastic force generated by the spring 65 to improve the stability of the central frame 4 and the sub-frame 5 between the two A steel cables 35. The force generated by the spring 65 and the reverse airflow has a certain corrective effect on the central frame 4 and the sub-frame 5, and also prevents the wind pressure on one side of the central frame 4 and the sub-frame 5 from being too high, which would cause the wind pressure stress to concentrate at the sliding column 18 at the bottom of the sub-frame 5, thereby avoiding the breakage of the sliding column 18 and the slippage of the central frame 4 and the sub-frame 5 on the outside of the two A steel cables 35.

[0075] Please see Figures 4-5 As a preferred embodiment of the present invention, a limiting ring 8 is fixedly connected to the outer side of the connecting plate 31. The limiting ring 8 is arc-shaped, and the connecting rod 32 and the limiting ring 8 are concentrically arranged.

[0076] A clamping rod 9 is fixedly connected to the outside of the rotating rod 33. The clamping rod 9 is L-shaped.

[0077] The angle between the side end of the limiting ring 8 and the clamping rod 9 is 5°.

[0078] In this embodiment, during the process of wind pressure on both sides of the central frame 4, the sub-frame 5 and the flexible photovoltaic panel installed on its top, the two A steel cables 35 bend longitudinally. At the same time, the rotating rod 33 rotates inside the limiting ring 8. As the airflow direction changes, and the angle between the side end of the limiting ring 8 and the clamping rod 9 is 5°, the rotating rod 33 is controlled to deflect within the limiting ring 8 within a range of ±5°, preventing the bending amplitude of the two A steel cables 35 from being too large.

[0079] Example 2: Please refer to Figures 1-3 and Figure 10 Based on Embodiment 1, this embodiment provides a flexible photovoltaic support technical solution with automatic orientation correction function: a tripod 10 is fixedly connected to the outside of the crossbar 2, two connecting plates 31 are installed on the inside of the tripod 10, and a pulley group 11 is fixedly connected to the inside of the tripod 10, with two rollers inside the pulley group 11.

[0080] A steel cable 35 passes between the two rollers;

[0081] A B steel cable 12 is fixedly connected between the two tripods 10, and the connecting post 63 is connected to the B steel cable 12;

[0082] Two steel cables, A (35) and B (12), are arranged in an isosceles triangle.

[0083] In this embodiment, steel cable 35 is installed between two rollers forming a pulley group 11 to prevent the two steel cables 35 from bending under wind pressure when the top or bottom surfaces of the center frame 4 and the sub-frame 5 are subjected to wind pressure, which would cause the steel cables 35 to fall off between the pulley group 11.

[0084] The B steel cable 12, which is arranged in a triangle with the two A steel cables 35, improves the stability of the connection between the central frame 4, the two A steel cables 35, and the B steel cable 12.

[0085] Please see Figures 2-3 As a preferred embodiment of the present invention, a connecting plate 13 is fixedly connected to the center position of one side of the crossbar 2;

[0086] The connecting frame assembly 1 includes an assembly plate 101 rotatably connected to the outside of the connecting plate 13. The outer side of the assembly plate 101 is provided with a positioning groove 102, and the included angle of the positioning groove 102 is 80°.

[0087] A positioning bolt 103 is fixedly connected to the outside of the connecting plate 13. The positioning bolt 103 is installed inside the positioning groove 102, and a positioning nut 104 is threadedly connected to the outside of the positioning bolt 103.

[0088] Specifically, the working principle of the pressure relief mechanism 7 is as follows:

[0089] For flexible photovoltaic panels installed in mountainous areas and across the sea, the tilt angle of the flexible photovoltaic panels needs to be determined before installation based on the annual wind direction and sunlight angle of the installation location.

[0090] Before installation, according to the required tilt angle of the flexible photovoltaic panel, the connecting plate 13 on the outside of the assembly panel 101 is rotated, so that the tilt angle of the crossbar 2 is deflected. At this time, the two steel cables A 35 and B 12 rotate synchronously.

[0091] During the rotation of the connecting plate 13, the positioning bolt 103 on the outside of the connecting plate 13 moves in the positioning groove 102 on the outside of the assembly plate 101. The included angle of the positioning groove 102 is 80°, which allows the flexible photovoltaic panel to deflect between 0° and 40° in both directions. After the flexible photovoltaic panel is adjusted to a suitable tilt angle, the positioning nut 104 is used to fix the position of the positioning bolt 103 inside the positioning groove 102, thereby fixing the angle of the crossbar 2. Only one adjustment is needed before installation. During later maintenance, when the tilt angle of the flexible photovoltaic panel needs to be changed, it is convenient to adjust the tilt angle of the crossbar 2.

[0092] Please see Figure 1 As a preferred embodiment of the present invention, the bottom of the assembly plate 101 is fixedly connected to a column 14;

[0093] A connecting plate 15 is symmetrically fixedly connected to the top of the assembly plate 101, and a cable 16 is installed on the outside of the connecting plate 15.

[0094] In this embodiment, the column 14 is used to install the assembly plate 101 on both sides of the mountain or river / sea location. The connecting plate 15 and the outer inclined cable 16 provide support for the column 14, preventing the two A steel cables 35 from bending and deforming when the central frame 4 and the sub-frame 5 are subjected to wind pressure, causing the column 14 to tilt and lean due to the tension of the A steel cables 35, which in turn causes the central frame 4 and the sub-frame 5 to slide on the outside of the two A steel cables 35.

[0095] Please see Figures 11-12 As a preferred embodiment of the present invention, a spring piece 17 is symmetrically and fixedly connected between the central frame 4 and the sub-frame 5, and the spring piece 17 is V-shaped.

[0096] In this embodiment, when the central frame 4 and the sub-frame 5 are subjected to wind pressure, the V-shaped elastic piece 17 between the central frame 4 and the sub-frame 5 also has the effect of wind pressure relief through the elastic force generated by the contraction and release.

[0097] Please see Figure 6 As a preferred embodiment of the present invention, the bottom of the subframe 5 is symmetrically and fixedly connected with sliding columns 18;

[0098] Two sliding posts 18 are provided on each side, and the sliding posts 18 are slidably connected to the steel cable 35.

[0099] In this embodiment, the sliding post 18 provided at the bottom of the subframe 5 allows the subframe 5 to slide between the two A steel cables 35, allowing the subframe 5 to slide slightly between the two A steel cables 35. The sliding post 18 and the A steel cables 35 are not connected by a rigid clamping method, which prevents the stress generated by the deformation of the A steel cables 35 from concentrating in the sliding post 18, thereby avoiding the breakage of the sliding post 18 and causing the center frame 4 and the subframe 5 to shift to the outside of the A steel cables 35.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
