Description

FIELD OF THE INVENTION

[0001] The present application relates to the technical field of flexible support, and in particular to a floating flexible photovoltaic support structure and floating photovoltaic system. BACKGROUND

[0002] Flexible photovoltaic supports feature large spans and high clearances, capable of achieving a span of 10 to 30 meters. It only requires the installation of foundations at appropriate positions and the tensioning of prestressed steel strands or steel wires, thereby enabling more efficient use of space and increasing the installed capacity. Due to its structural characteristics, the flexible photovoltaic support can be flexibly arranged in complex marine, river, or lake environments, adapting to different terrain and water depth conditions to maximize the utilization of spatial resources in oceans, rivers, and lakes. However, floating flexible photovoltaic supports tend to drift with the waves. In addition to being affected by strong winds, they may surge and overturn when encountering large waves, resulting in poor stability and significant property losses.

[0003] Accordingly, how to improve the technical defects existing in the prior art has long been a problem to be urgently solved by those skilled in the art. SUMMARY

[0009] In some embodiments, the cable assembly further comprises a wind-resistant cable, which passes through the at least two columns and is located below the load-bearing cable; a number of the load-bearing cables is two, and a wind-resistant frame is provided between the two loadbearing cables and the wind-resistant cable.

[0010] In some embodiments, the floating flexible photovoltaic support further comprises a second counterweight assembly, which comprises a second stay cable and a second counterweight block; one end of the second stay cable is anchored to the bottom of the water, and the other end is connected to the second counterweight block; and the second counterweight assembly is arranged on the wind-resistant frame and provides a downward force.

[0011] In some embodiments, the floating flexible photovoltaic support further comprises a second pulley assembly, which comprises a second pulley and a second pulley bracket; the second pulley is located in the second pulley bracket, the second stay cable is wrapped around the second pulley, and the second pulley assembly is connected to the wind-resistant frame to set the second counterweight block on the wind-resistant frame. 2025267416   13 Nov 2025

[0012] In some embodiments, the wind-resistant frame comprises a plurality of connecting rods, each of the connecting rods comprises a main body portion and ear portions provided at both ends of the main body portion, the second pulley bracket comprises a base plate and two limiting plates located on both sides of the base plate, the second pulley is located between the two limiting plates, and the base plate is fixedly connected to the ear portions of the connecting rods by fasteners.

[0013] In some embodiments, multiple second pulley assemblies are provided, which are respectively located at end points where the wind-resistant frame is connected to the load-bearing cables.

[0014] In some embodiments, said at least two columns further comprise a second column, and the first column and the second column float on the water surface through pontoons respectively; or the second column is fixed to a ground.

[0015] In some embodiments, a number of the second columns is two, the two second columns are fixed to the ground, and top ends of the two second columns are inclined away from each other; and the two second columns are each provided with a side anchor cable on a side away from each other, one end of the side anchor cable is connected to the top end of the second column, and the other end is connected to the ground, and the side anchor cable is arranged perpendicular to the ground.

[0016] In some embodiments, the first stay cable and the second stay cable are anchored to the bottom of the water respectively through a third counterweight block; and / or the floating mechanism is a pontoon, and the first column is fixedly connected to the pontoon.

[0017] The present application also discloses a floating flexible photovoltaic system, which comprises:

[0018] photovoltaic modules and a floating flexible photovoltaic support provided in any of the above embodiments.

[0019] This application has at least one of the following beneficial effects:

[0020] 1. In the present application, a first counterweight assembly is arranged on the first column, providing a downward force to the first column. Simultaneously, a first stay cable within the first counterweight assembly is anchored to the bottom of the water, constraining the first column within a desired range and preventing it from drifting away with the wind and waves. When wind and waves approach, the first column will move up and down with the waves. When 2025267416   13 Nov 2025 the first column tends to move upward, the first counterweight block, under the action of its own gravity, provides a downward pull to the second column. Furthermore, the end of the first stay cable anchored to the bottom of the water also provides a downward pull to the first column, thereby reducing the upward displacement of the first column, thereby counteracting the impact of wind and waves, stabilizing the entire system, and thereby minimizing property damage caused by strong winds and other factors.

[0021] 2. In the present application, the first pulley bracket for fixing the first pulley comprises two fixing plates spaced-apart in an interval, the interval between the two fixing plates being less than the width of the first counterweight block. This allows the first counterweight block to be positioned. In high-wave and windy conditions, if the pulling force of the first counterweight block and the first stay cable is unable to offset the upward force of the first column, the first counterweight block slides to the first pulley bracket, where the fixing plates can mechanically brake the first counterweight block, thereby resisting the impact of strong winds and waves.

[0022] 3. In the present application, there are two first pulleys in the first pulley assembly, and the first stay cable is wrapped around the two first pulleys with a large number of wraps. In this way, when the first column rises and falls under the action of wind and waves, the first stay cable is limited by the friction between itself and the first pulley, and the sliding speed becomes slower. The more wraps the first stay cable has, the more obvious the reduction in its sliding speed. The overall structure of the floating flexible photovoltaic support is more stable, and can better cope with the impact of large waves and wind in windy weather.

[0023] 4. In the present application, there are two load-bearing cables, which can achieve stable support for photovoltaic modules with fewer components. Meanwhile, the provision of two loadbearing cables is also more conducive to the installation of wind-resistant frames, improving the stability of the overall structure of the floating flexible photovoltaic support. The present application further provides a second counterweight assembly on the wind-resistant frame. When the floating flexible photovoltaic support is affected by an uplift wind pressure, the second counterweight block in the second counterweight assembly will provide a downward pulling force for the floating flexible photovoltaic support under the action of its own gravity. Meanwhile, the end of the second stay cable anchored to the bottom of the water can also provide a downward pulling force for the floating flexible photovoltaic support, thereby improving the anti-overturning ability of the floating flexible photovoltaic support. 2025267416   13 Nov 2025 BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In the following description, specific details such as specific system structures and technologies are provided for illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may be implemented in other embodiments without these specific details.

[0039] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of various components of the present application are not absolute but relative. These descriptions are 2025267416   13 Nov 2025 applicable when these components are in the positions shown in the accompanying drawings. If the descriptions of the positions of these components are changed, these directional indications will also change accordingly.

[0040] In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0041] According to a specific embodiment provided by this application, referring to FIGS. 1-4, a floating flexible photovoltaic support 100 is disclosed, which comprises a column assembly, a beam assembly, and a cable assembly. The column assembly comprises at least two columns spaced apart; the beam assembly comprises at least two beams 190, each of which is disposed at the top of each column in a one-to-one correspondence; and the cable assembly comprises loadbearing cables 130, which are attached to the beams 190 on at least two columns and are used to support photovoltaic modules 200. The number of load-bearing cables 130 is preferably two to ensure stable support of the photovoltaic modules 200.

[0042] The floating flexible photovoltaic support 100 has the advantages of large span, high clearance, less consumables, strong wind resistance, adaptability to large inclination angles, simple installation, reduced difficulty in pile foundation construction, lower cost, etc. It does not require large-scale installation, can adapt to different terrain and water depth conditions, and is suitable for more investors.

[0043] Furthermore, referring to FIGS. 1-5, said at least two columns comprise a first column 110, which floats on the water surface 302 via a floating mechanism. Specifically, a pontoon 111 is provided on the water surface 302, and the pontoon 111 floats on the water surface 302, with one end of the first column 110 fixed to the pontoon 111. The floating flexible photovoltaic support 100 further comprises a first counterweight assembly, which comprises a first stay cable 161 and a first counterweight block 162. One end of the first stay cable 161 is anchored to the bottom of the water 302, anchoring the first column 110 within the desired range so that it will not drift away with the wind and waves. The other end of the first stay cable 161 is connected to the first counterweight block 162. The first counterweight assembly is provided on the first column 110 and is used to provide a downward force to the first column 110. In addition to the pontoon 111, the floating mechanism can also be other forms such as a floating box, a group of floating blocks, and a pull rope. 2025267416   13 Nov 2025

[0044] When wind and waves come, the first column 110 will move up and down with the fluctuations. When the first column 110 tends to move upward, the first counterweight block 162 will provide downward pulling force to the first column 110 under the action of its own gravity, thereby reducing the upward displacement of the first column 110. During this process, the end of the first stay cable 161 anchored to the bottom of the water 302 can also provide downward pulling force to the first column 110, cooperating with the first counterweight block 162 to offset the upward floating tendency of the first column 110, making the entire system stable, thereby reducing property damage caused by strong winds and other factors to the floating flexible photovoltaic support 100.

[0045] Specifically, referring to FIG. 5, the first stay cable 161 secures the first counterweight block 162 to first column 110 via a first pulley assembly 170. The first pulley assembly 170 comprises a first pulley 171 and a first pulley bracket 172. The first pulley 171 is mounted to the first column 110 via the first pulley bracket 172. The first pulley bracket 172 comprises two fixing plates 1721 spaced apart, which are welded to the sidewalls of the first column 110. The first pulley 171 is rotatably mounted between the two fixing plates 1721. The spacing between the two fixing plates 1721 is smaller than the width of the first counterweight block 162, enabling quick positioning of the first counterweight block 162. In this way, when dealing with strong waves and strong winds, once the tension of the first counterweight block 162 and the first stay cable 161 is unable to offset the force that causes the first column 110 to float, the first counterweight block 162 will slide to the first pulley bracket 172, and the fixed plate 1721 will limit the first counterweight block 162 to form a mechanical brake to resist the impact of strong winds and waves, effectively improving the ability of the floating flexible support to cope with the impact of strong waves and wind, and improving stability.

[0046] Preferably, referring to FIGS. 4 and 5, eight first pulley assemblies 170 are provided so that the floating flexible photovoltaic support 100 can better withstand the impact of wind and waves. The eight first pulley assemblies 170 are evenly spaced, which helps to evenly distribute the force on the first column 110, making it less likely to capsize due to unbalanced force and providing better stability.

[0047] In actual production, the number of first pulleys 171 in each first pulley assembly 170 can be one or more. In this embodiment, referring to FIG. 5, the number of first pulleys 171 in each pulley assembly is preferably two. The first stay cable 162 is wound around the two first pulleys 2025267416   13 Nov 2025 171, allowing for multiple turns. This arrangement provides a more balanced force distribution, and when facing large waves, the multiple windings increase the friction between the first stay cable 162 and the first pulleys 171, thereby reducing the sliding speed of the first stay cable 162. The greater the number of windings, the more pronounced the damping effect, resulting in a mechanical braking function.

[0048] Specifically, when the first column 110 rises and falls under the action of wind and waves, the first stay cable 162 can slide through the first pulley 171, and friction can be generated between the first stay cable 162 and the first pulley 171, thereby hindering the sliding of the first stay cable 162 and reducing the sliding speed of the first stay cable 162. Therefore, in this embodiment, by providing two first pulleys 171, the number of windings of the first stay cable 162 is increased, thereby slowing down the sliding speed of the first stay cable 162. As the number of windings of the first stay cable 162 increases, the degree of reduction in the sliding speed of the first stay cable 162 is more obvious, and the overall structure of the floating flexible photovoltaic support 100 is more stable, and it can better cope with the impact of large waves and wind in windy weather.

[0049] In one exemplary embodiment, said at least two columns further comprise a second column 120, and the first column 110 and the second column 120 are each floated on the water surface 302 via the pontoon 111. Preferably, there are two second columns 110, one located on either side of the first column 110. In this case, the second column 120 is also equipped with eight first pulley assemblies 170 and corresponding first stay cables 162 and first counterweight blocks 162 to withstand large wave impacts and wind forces.

[0050] Of course, in actual applications, one of the two second columns 120 may float on the water surface 302 via the pontoon 121, while the other may be fixed to the ground 301. Alternatively, referring to FIGS. 1 and 2, both second columns 120 may be fixed to the ground 301, with only the first column 110 floating on the water surface 302 via the pontoon 111. Although this arrangement sacrifices the possibility of constructing the floating flexible photovoltaic support 100 in the open sea, the overall structure is more stable. As long as it is constructed near the coast, such as near the sea or an estuary, it can significantly reduce the property losses caused by the floating flexible support when affected by typhoons and other factors. 2025267416   13 Nov 2025

[0051] Specifically, referring to FIGS. 1-3, the second columns 120 are fixed to the ground 301, and the tops of the two second columns 120 are inclined away from each other, thereby being inclined relative to the ground 301. Compared with being vertically installed on the ground 301, this configuration provides better wind resistance. In addition, the two second columns 120 are each provided with a side anchor cable 121 on the side away from each other. One end of the side anchor cable 121 is connected to the top of the second column 120, and the other end is connected to the ground 301. The side anchor cable 121 is arranged perpendicular to the ground 301, which is conducive to the stable fixation of the second column 120, thereby further improving the stability of the overall structure of the floating flexible photovoltaic support 100. The angle between the second column 120 and the load-bearing cable 130 is the same as the angle between the second column 120 and the side anchor cable 121. The second column 120 simultaneously bears the horizontal tension F1 from the load-bearing cable 130 and the vertical downward tension F2 from the side anchor cable 121. When the angle between the second column 120 and the load-bearing cable 130 is the same as the angle between the second column 120 and the side anchor cable 121, the direction of the resultant force F of the tension F1 and the tension F2 coincides with the axis of the second column 120. The second column 120 is an axially compressed member and is not affected by horizontal shear force. This allows the second column 120 to be designed without horizontal shear force. The shear-free design of this embodiment can avoid the risk of vertical column damage caused by horizontal displacement of the foundation due to excessive horizontal force, thereby reducing costs. In this embodiment, the inclination angle of the second column 120 relative to the ground 301 is preferably 45°.

[0052] Specifically, referring to FIG. 3, an inclined pile foundation 122 is installed on the ground 301. The second column 120 is fixed to the inclined pile foundation 122 by anchor bolts or welding. The inclined pile foundation 122 is coaxially arranged with the second column 120. Conversely, a side anchor support 123 is installed on the ground 301. The side anchor cable 121 is tightened to the top of the second column 120 by pulling the anchor.

[0053] In one specific embodiment, as shown in FIGS. 2, 3, 5 and 6, a beam 190 is installed at the top of each of the second column 120 and the first column 110. The beam 190 is inclined relative to the horizontal plane. In this case, the load-bearing cable 130 is threaded through the beam 190, allowing the photovoltaic module 200 to be inclined relative to the horizontal plane, thereby achieving greater power generation and improving power generation efficiency. 2025267416   13 Nov 2025

[0054] For example, the cable assembly may further comprise a wind-resistant cable 140, which passes through the first column 110 and the second column 120 and is located below the loadbearing cable 130. Specifically, one end of the load-bearing cable 130 and the wind-resistant cable 140 are respectively fixed to the beam 190 at the top of one second column 120, and the other end passes through the beam 190 at the top of the first column 110 and is fixed to the beam 190 at the top of the other second column 120. In this case, the number of load-bearing cables 130 is preferably two, and a wind-resistant frame 150 is provided between the two load-bearing cables 130 and the wind-resistant cable 140. One end of the wind-resistant frame 150 is fixedly connected to the two load-bearing cables 130, and the other end is fixedly connected to the windresistant cable 140 below. The load-bearing cables 130 and the wind-resistant cables 140 are connected by the wind-resistant frame 150, thereby increasing the stability of the flexible photovoltaic support and thus improving the wind resistance of the floating flexible support.

[0055] The wind-resistant frame 150 may be a triangular pyramid, a quadrangular pyramid, a pentagonal pyramid, or another polygonal pyramidal structure. In the present embodiment, referring to FIG. 6, the wind-resistant frame 150 is a triangular pyramidal structure. The overall framework of the triangular wind-resistant frame 150 is formed by connecting a plurality of connecting rods 151 end to end. Each connecting rod 151 comprises a main body portion and ear portions provided at both ends of the main body portion. The ear portions are integrally formed with the main body portion by bending or welding. Fasteners pass through the ear portions of adjacent connecting rods 151 to fix the connecting rods 151 together. In the present embodiment, the fasteners are eye bolts, whose threaded rod portions pass through the ear portions of the connecting rods. The load-bearing cables 130 and the wind-resistant cables 140 respectively pass through the eye portions of the corresponding eye bolts, thereby being connected to the windresistant frame 150.

[0056] In this embodiment, two load-bearing cables 130 are used, which allows for stable support of the photovoltaic module 200 with fewer components, making installation easy and cost-effective. Furthermore, the provision of two load-bearing cables 130 facilitates the installation of the wind-resistant frame 150 and improves the overall structural stability of the floating flexible photovoltaic support 100.

[0057] Preferably, referring to FIGS. 2 and 6, the floating flexible photovoltaic support 100 further comprises a second counterweight assembly, the second counterweight assembly 2025267416   13 Nov 2025 comprises a second stay cable 163 and a second counterweight block 164, one end of the second stay cable 163 is anchored to the bottom of the water 302, and the other end is connected to the second counterweight block 164. The second counterweight assembly is arranged on the windresistant frame 150 and provides a downward force.

[0058] In this embodiment, referring to FIGS. 6 and 7, the second stay cable 163 sets the second counterweight block 164 on the wind-resistant frame 150 through the second pulley assembly 180. Specifically, the wind-resistant frame 150 is provided with a second pulley assembly 180, which comprises a second pulley 181 and a second pulley bracket 182. The second pulley 181 is arranged in the second pulley bracket 182. The second stay cable 163 is wound around the second pulley 181. The second pulley bracket 182 is fixed to the ear portions of the connecting rods 151 of the wind-resistant frame 150. Furthermore, the second pulley bracket 182 comprises a base plate 1821 and limiting plates 1822 located on both sides of the base plate 1821. The two ends of the rotating shaft are respectively fixed on the two limiting plates 1822 and pass through the axis of the second pulley 181, thereby limiting the second pulley 181 between the two limiting plates 1822. The threaded rod of the eye bolt fixing the wind-resistant frame 150 passes through the ear portion of the corresponding connecting rod 151 and continues to pass through the base plate 1821, thereby fixing the second pulley assembly 180 on the wind-resistant frame 150.

[0059] In this embodiment, the second pulley assembly 180, the second stay cable 163 and the second counterweight block 164 are arranged in a one-to-one correspondence, and the number of the second pulley assembly 180, the second stay cable 163 and the second counterweight block 164 is three respectively, and the three second pulley assemblies 180 are respectively located at the end positions where the wind-resistant frame 150 is connected to the load-bearing cable 130.

[0060] When the floating flexible photovoltaic support 100 is subjected to uplift wind pressure, the second counterweight block 164 will provide a downward pulling force to the floating flexible photovoltaic support 100 under the action of its own gravity. Meanwhile, the second stay cable 163 anchored at one end of the water bottom 302 can also provide a downward pulling force to the floating flexible photovoltaic support 100, thereby improving the anti-overturning ability of the floating flexible photovoltaic support 100 to cope with strong winds.

[0061] In the above-mentioned embodiments, the first stay cable 161 and the second stay cable 163 are respectively anchored to the water bottom 302 through the third counterweight block 165, wherein the weight of the third counterweight block 165 is preferably 2 tons or more, and it can 2025267416   13 Nov 2025 sink to the bottom of the water to play a better anchoring role. Meanwhile, it can also provide a downward pulling force for the floating flexible photovoltaic support 100 under the action of its own gravity, and cooperate with the first counterweight block 162 and the second counterweight block 162 to cope with the impact of wind and waves when wind and waves come.

[0062] Specifically, during on-site assembly of the floating flexible photovoltaic support structure 100, pile driving shall be performed first. The inclined pile foundations 122 along the shore are driven into the ground at designed intervals so that their tops are aligned on a horizontal line. The pile-driving depth shall be theoretically calculated and constructed in accordance with standard specifications. Subsequently, the second columns 120 are installed. Each second column 120 is fixed onto the inclined pile foundation 122 by anchor bolts or by welding, depending on the site conditions. The installation angle of each second column 120 should be carefully controlled to ensure that the beams 190 mounted thereon maintain a uniform inclination. Next, the first column 110 is installed. The height above the water surface is measured, and after the span is determined, the third counterweight blocks 165 are submerged into the water bottom in eight directions. Before sinking, the first stay cable 162 is secured to the third counterweight block 165. Once the third counterweight block 165 is confirmed to have sunk to the bottom, the first stay cable 162 is wrapped around the first pulley 171 and secured to the first counterweight block 162 and the pontoon 111. The weight of the first counterweight block 162 must be calculated in advance. Then, the load-bearing cables 130 are installed. Each load-bearing cable 130 is tensioned across the first column 110 and the beam 190 of the second column 120 on both sides in a pulling-anchor manner, and the pretension force shall be determined through calculation. After that, the wind-resistant frame 150 is installed. The wind-resistant frame 150 is first preassembled below, and its installation position is measured. Once the position is confirmed, it is fixed to the load-bearing cables 130 by means of U-shaped locks or clamps. A steel wire rope is then tightened from below to form the wind-resistant cable 140. Subsequently, the first pulleys 171 are fixed to the wind-resistant frame 150 or to the load-bearing cables 130. The submerging positions of the third counterweight blocks 165 are then measured (the same procedure as when the upper third counterweight blocks 165 are submerged). Once determined, the third counterweight blocks 165 are submerged, and the second stay cables 163 are wound around the second pulleys 181, followed by fixing the second counterweight blocks 164. The weight of each second counterweight block 164 should also be calculated in advance. Next, the 2025267416   13 Nov 2025 side anchor cables 121 are installed. The side anchor supports 123 are fixed onto the ground 301, and the side anchor cables 121 are tensioned and secured to the beam 190 of the second column 120 in a pulling-anchor manner. It should be noted that, in this design, since the second columns 120 are installed on inclined pile foundations 122, the side anchor cables 121 must be tightened so that they extend vertically downward, forming a right angle with the ground 301. Finally, the photovoltaic modules 200 are mounted onto the load-bearing cables 130 using pressing blocks, thereby completing the assembly of the floating flexible photovoltaic support 100.

[0063] The present application further provides a floating flexible photovoltaic system suitable for offshore, lake, riverbed and other scenarios, which comprises photovoltaic modules 200 and an floating flexible photovoltaic support 100 provided by any of the above embodiments, and the photovoltaic modules 200 are arranged on the floating flexible photovoltaic support 100.

[0064] Compared to traditional rigid fixed supports, flexible photovoltaic supports have significantly larger spans and higher clearances, enabling more efficient use of space and increasing installed capacity for floating photovoltaic power stations. To address the issue of flexible photovoltaic systems drifting with the current and potentially capsizing in strong waves, the present application employs two side columns fixed to the shore and equipped with eight cable counterweight structures to prevent drifting and reduce the distance the flexible photovoltaic system floats when impacted by wind and waves, thereby minimizing property damage caused by strong winds and other factors.

[0065] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant description of other embodiments.

[0066] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of this application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications should also be considered as the scope of protection of this application.
