Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power generation and agricultural facilities technology, and particularly relates to a double-layer suspension flexible photovoltaic support with irrigation function. Background Technology

[0002] With the deep integration of the new energy industry and modern agriculture, composite utilization models such as "agricultural-solar complementarity" and "fishery-solar complementarity" have been widely promoted. Flexible photovoltaic supports, with their advantages of large span, strong terrain adaptability, and convenient construction, have been widely used in complex scenarios such as mountains, tidal flats, and farmland. These supports typically adopt a double-layer suspension structure design, with the main cable supporting the photovoltaic modules and the stabilizing cable ensuring the overall structural balance, thus achieving efficient and synergistic utilization of photovoltaic power generation and land resources.

[0003] However, existing double-layer suspension flexible photovoltaic supports still face two major technical challenges in practical applications: First, the design for wind-resistant stability is limited. Current lateral stabilization structures for these supports are mainly divided into two categories. One type uses rigid struts, which, while providing some support stiffness, are bulky, have high transportation and installation costs, and poor adaptability to terrain, making them unsuitable for large-span deployments. The other type uses pure cable structures (such as wind-resistant cables and steel strands), which, while lightweight, require significant prestress to suppress wind-induced vibrations (including flutter and vortex-induced vibrations), and lack effective damping energy dissipation mechanisms. Over long-term use, these structures are prone to fatigue damage due to vibration, affecting the service life and reliability of the supports.

[0004] Secondly, the single function leads to waste of resources and construction. The existing support structure's lateral connecting components only serve the function of structural stability. However, in the "agricultural-solar complementary" scenario, irrigation pipelines need to be laid separately for crop irrigation. This not only increases material costs but also requires additional construction procedures such as pipeline excavation, laying, and fixing, resulting in repetitive work and land occupation. This not only increases the initial investment of the project but also brings inconvenience to subsequent operation and maintenance.

[0005] Therefore, developing an integrated structure that can take into account lateral stability, damping and vibration reduction, and agricultural irrigation functions, and solving the problems of insufficient wind resistance, single function, construction and material waste of existing supports, has become an urgent technical need to be addressed in this field. It is of great significance to promoting the quality and efficiency of photovoltaic and agricultural integrated utilization models. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a double-layer suspension flexible photovoltaic support with irrigation function.

[0007] To achieve the above objectives, the present invention provides a double-layer suspension flexible photovoltaic support with irrigation function, comprising: Multiple photovoltaic support units are arranged side by side. Each photovoltaic support unit includes multiple bases arranged side by side. The bases are vertically fixed to the ground. The multiple bases are connected in series by stabilizing cables. A main cable is connected to the top of the stabilizing cables by a triangular support bracket. The main cable is used to install photovoltaic modules. Multiple flexible water pipes are arranged in parallel; the flexible water pipes are suspended below the stabilizing cables, and the multiple stabilizing cables are connected in series; the flexible water pipes are tensioned and anchored to the ground at both ends; the multiple flexible water pipes are connected to a water source through a main water pipe; and spray components are spaced apart on the flexible water pipes.

[0008] Optionally, the flexible water pipe is connected to the bottom of the triangular support bracket.

[0009] Optionally, the triangular support bracket is made of three hollow round steel pipes hinged together in an inverted triangle configuration, with the stabilizing cable connected at the bottom hinge point and the main cable connected at the top hinge point.

[0010] Optionally, the two hollow round steel pipes at the bottom are hinged together by a central frame, and ear plates extend from both sides of the central frame. The two hollow round steel pipes at the bottom are bolted to the two ear plates respectively. A central hole is opened in the middle of the central frame, and the stabilizing cable passes through the central hole.

[0011] Optionally, the flexible water pipe is fixed to the bottom of the central frame by two arc-shaped clamps. The flexible water pipe is clamped between the two arc-shaped clamps. The top of the two arc-shaped clamps is bolted to the bottom of the central frame, and the bottom of the two arc-shaped clamps is fastened together by bolts.

[0012] Optionally, the stabilizing cable is mounted on the base in the middle and fixed to the ground at both ends.

[0013] Optionally, the flexible water pipe is a high-density polyethylene pipe or a reinforced PVC pipe, and the inner wall of the flexible water pipe is embedded with a high-strength steel wire or polyester fiber braided layer.

[0014] Optionally, the spray assembly includes a spray head that is connected to the flexible water pipe and has an adjustable angle.

[0015] Optionally, the spray head integrates a valve.

[0016] Optionally, the spray assembly further includes a stator base and a rotor. The stator base has a two-half structure and is clamped to the flexible water pipe by bolts. The rotor is rotatably connected to the outside of the stator base. A dynamic rotating sealing ring assembly is installed in the groove between the stator base and the rotor. An annular dynamic sealing water channel is formed between the stator base and the rotor and communicates with the flexible water pipe. The spray head is fixed to the rotor and communicates with the annular dynamic sealing water channel.

[0017] Compared with the prior art, the present invention has the following advantages and technical effects: By organically combining multiple photovoltaic support units arranged side by side with multiple parallel, tensioned, and ground-anchored flexible water pipes, this system offers multiple advantages, including structural stability, functional versatility, and application adaptability. Each photovoltaic support unit includes a base arranged side by side and vertically fixed to the ground. Multiple bases are connected in series by stabilizing cables. Above the stabilizing cables, a triangular support bracket connects to the main cable used for installing photovoltaic modules. The combination of double-layer suspension cables and triangular support brackets gives the support system strong terrain adaptability and large-span deployment capability, flexibly adapting to various application scenarios such as mountainous agricultural-photovoltaic integration. The flexible water pipes serve as lateral connecting components, connecting the stabilizing cables. When tensioned, they provide reliable lateral stiffness to the support system. Combined with the mass damping effect formed by the water inside the pipes, they effectively suppress wind-induced vibrations, improving wind resistance stability without the need for large prestresses, thus replacing the single wind-resistant function of traditional rigid struts or pure cable structures. Meanwhile, the flexible water pipe connects to the water source through the main water pipe, and together with the sprinkler components set at intervals on it, it can directly realize precise irrigation of the farmland below the support without the need to lay separate irrigation pipelines, avoiding repeated construction and material waste. It achieves an integrated design of structural stability components and irrigation function components, which has the dual benefits of photovoltaic power generation and agricultural irrigation. Moreover, the overall structure is lightweight and easy to install, which significantly reduces the initial investment and operation and maintenance costs of the project. Attached Figure Description

[0020] 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.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figures 1 to 5 As shown, this embodiment provides a double-layer suspension flexible photovoltaic support with irrigation function, including: Multiple photovoltaic support units are arranged side by side. Each photovoltaic support unit includes multiple bases 1 arranged side by side. The bases 1 are vertically fixed to the ground. The multiple bases 1 are connected in series by stabilizing cables 2. A main cable 4 is connected above the stabilizing cables 2 by a triangular support bracket 3. The main cable 4 is used to install photovoltaic modules 5. Multiple flexible water pipes 6 are arranged in parallel; the flexible water pipes 6 are suspended below the stabilizing cables 2 and the multiple stabilizing cables 2 are connected in series; the flexible water pipes 6 are tensioned and anchored to the ground at both ends; the multiple flexible water pipes 6 are connected to the water source through the main water pipe 7; and spray components 8 are installed at intervals on the flexible water pipes 6.

[0023] By organically combining multiple photovoltaic support units arranged side by side with multiple parallel, tensioned, and ground-anchored flexible water pipes 6, the system possesses multiple advantages, including structural stability, functional versatility, and application adaptability. Each photovoltaic support unit includes a base 1 arranged side by side and vertically fixed to the ground. Multiple bases 1 are connected in series by stabilizing cables 2. Above the stabilizing cables 2, a main cable 4 for installing photovoltaic modules 5 is connected via a triangular support bracket 3. The combination of double-layer suspension cables and triangular support brackets 3 gives the support system strong terrain adaptability and large-span deployment capability, allowing for flexible adaptation to various application scenarios such as mountainous agricultural-photovoltaic integration. The flexible water pipes 6 serve as lateral connecting components connecting the stabilizing cables 2. When tensioned, they provide reliable lateral stiffness to the support system. Combined with the mass damping effect formed by the water inside the pipes, they can effectively suppress wind-induced vibrations, improving wind resistance stability without the need for large prestressing, thus replacing the single wind-resistant function of traditional rigid struts or pure cable structures. Meanwhile, the flexible water pipe 6 connects to the water source through the main water pipe 7, and together with the sprinkler components 8 set at intervals on it, it can directly realize precise irrigation of the farmland below the support without the need to lay irrigation pipelines separately, avoiding repeated construction and material waste. It achieves an integrated design of structurally stable components and irrigation functional components, with the dual benefits of photovoltaic power generation and agricultural irrigation. Moreover, the overall structure is lightweight and easy to install, which significantly reduces the initial investment and operation and maintenance costs of the project.

[0024] In some alternative implementations, the flexible water pipe 6 is connected to the bottom of the triangular support bracket 3.

[0025] In some alternative implementations, the triangular support 3 is made of three hollow round steel pipes hinged together in an inverted triangle configuration, with the stabilizing cable 2 connected at the bottom hinge point and the main cable 4 connected at the top hinge point.

[0026] The triangular support bracket 3 is constructed from three hollow round steel tubes hinged together in an inverted triangular arrangement. This structural design effectively reduces the bracket's weight while ensuring support strength. The top hinge point of the triangular support bracket 3 connects to the main cable 4, which serves as the load-bearing carrier for the photovoltaic module 5. The stable connection at the top hinge point enables the horizontal installation of the photovoltaic module 5. The bottom hinge point of the triangular support bracket 3 is specifically used to connect the stabilizing cable 2, which connects multiple parallel bases 1 in series, forming a laterally balanced support system that provides vertical stiffness and lateral stability for the entire support system. High-strength hinges are used at the joints of the three hollow round steel tubes to ensure that they do not loosen or deform under complex outdoor environments and wind loads.

[0027] In some alternative implementations, the two hollow round steel pipes at the bottom are hinged together by the central frame 9, and ear plates extend from both sides of the central frame 9. The two hollow round steel pipes at the bottom are bolted to the two ear plates respectively. A central hole is opened in the middle of the central frame 9, and the stabilizing cable 2 passes through the central hole.

[0028] To ensure reliable hinged connection of the two hollow round steel pipes at the bottom and through-connection of the stabilizing cable 2, a central frame 9 is provided at the bottom hinge point of the triangular support bracket 3 in this embodiment. The central frame 9 is a one-piece steel structure with symmetrically extending ear plates on both sides. Bolt holes are pre-set on the ear plates. The ends of the two hollow round steel pipes at the bottom are fastened to the ear plates on the corresponding sides by bolts, realizing the hinged connection between the two and ensuring the structural integrity and adjustability of the triangular support bracket 3. At the same time, a through-hole is opened in the middle of the central frame 9 along the longitudinal direction. The stabilizing cable 2 passes through the central hole, which not only achieves precise positioning of the stabilizing cable 2 and the triangular support bracket 3, but also limits the stabilizing cable 2 through the hole wall, preventing lateral displacement of the stabilizing cable 2 during the stress process and ensuring the consistency of stress after multiple bases 1 are connected in series by the stabilizing cable 2.

[0029] In some alternative implementations, the flexible water pipe 6 is fixed to the bottom of the central frame 9 by two arc-shaped clamps 10. The flexible water pipe 6 is clamped between the two arc-shaped clamps 10. The top of the two arc-shaped clamps 10 is bolted to the bottom of the central frame 9, and the bottom of the two arc-shaped clamps 10 is fastened together by bolts.

[0030] The flexible water pipe 6, as a core component combining lateral stability and irrigation functions, is connected to the triangular support bracket 3 via two arc-shaped clamps 10. The specific connection method is as follows: the arc-shaped clamps 10 adopt an arc-shaped structure adapted to the outer wall of the flexible water pipe 6, and the two clamps are arranged opposite each other to form a cavity for enclosing the flexible water pipe 6. During assembly, the flexible water pipe 6 is first placed in the cavity formed by the two arc-shaped clamps 10, ensuring that the outer wall of the water pipe is tightly fitted to the inner wall of the clamps; then, the tops of the two arc-shaped clamps 10 are fastened to the bottom of the central frame 9 using bolts, thus fixing the clamps to the triangular support bracket 3; finally, the bolts are inserted into the corresponding holes at the bottom of the two arc-shaped clamps 10 and the nuts are tightened, using radial clamping force to firmly hold the flexible water pipe 6, completing the fixation of the flexible water pipe 6 to the bottom of the triangular support bracket 3.

[0031] During assembly, it is necessary to ensure that the clamping force of the arc-shaped clamping plate 10 on the flexible water pipe 6 is evenly distributed to avoid excessive local pressure that could damage the pipe wall. At the same time, it is necessary to ensure that the flexible water pipe 6 is firmly connected to the central frame 9 under tension and does not undergo relative displacement, so that the flexible water pipe 6 can effectively play a lateral restraint role and resist the lateral vibration and displacement of the support system.

[0032] In some alternative implementations, the stabilizing cable 2 is mounted on the base 1 in the middle and fixed to the ground at both ends.

[0033] The structure of the stabilizing cable 2, which is erected in the middle of the base 1 and fixed to the ground at both ends, provides multi-point support and fixation for the stabilizing cable 2, preventing sagging caused by large spans, ensuring uniform tension distribution, and improving the support stiffness and flatness of the support unit. The combined fixing method forms a stable force-bearing system, enhancing the tensile strength and displacement resistance of the stabilizing cable 2, suppressing swaying deformation under external forces such as wind loads, and reducing the impact on other components. At the same time, it disperses local stress, avoids stress concentration losses, extends the service life of the stabilizing cable 2, provides a stable foundation for the suspension and series connection of the flexible water pipe 6, ensures that the flexible water pipe 6 remains taut to fully exert its lateral stability and irrigation functions, and improves the reliability and stability of the entire support system.

[0034] In some alternative implementations, the flexible water pipe 6 is a high-density polyethylene pipe or a reinforced PVC pipe, and the inner wall of the flexible water pipe 6 is embedded with a high-strength steel wire or polyester fiber braided layer.

[0035] The flexible water pipe 6 uses high-density polyethylene or reinforced PVC pipe, with a structure incorporating high-strength steel wire or polyester fiber braided layers inside the pipe wall. This structure fully utilizes the excellent weather resistance and corrosion resistance of the two basic pipe materials, enabling long-term stable operation in complex outdoor environments. The embedded reinforcement layer significantly enhances the tensile strength of the water pipe, ensuring stable lateral tensile force under tension, preventing deformation or breakage that could affect the lateral stability of the support system. Simultaneously, its excellent flexibility facilitates adaptation to the layout and installation of the support system, reliably meeting the dual requirements of serving as a structural connection component and a water supply and irrigation component. This extends its service life, reduces maintenance frequency, and ensures the long-term stable operation of the support system, providing both photovoltaic power generation and agricultural irrigation benefits.

[0036] In some alternative implementations, the spray assembly 8 includes a spray head 81 connected to the flexible water pipe 6, and the spray head 81 is angle-adjustable.

[0037] In some alternative implementations, the spray head 81 integrates a valve.

[0038] In some alternative embodiments, the spray assembly 8 further includes a stator base 82 and a rotor 83. The stator base 82 has a two-part structure and is clamped to the flexible water pipe 6 by bolts. The rotor 83 is rotatably connected to the outside of the stator base 82. A dynamic rotating sealing ring assembly 84 is installed in the groove between the stator base 82 and the rotor 83. An annular dynamic sealing water channel 85 is formed between the stator base 82 and the rotor 83 and communicates with the flexible water pipe 6. The spray head 81 is fixed to the rotor 83 and communicates with the annular dynamic sealing water channel 85.

[0039] The sprinkler assembly 8 mainly consists of a stator base 82, a rotor 83, a dynamic rotating sealing ring assembly 84, and a sprinkler head 81. These components work together to achieve stable water delivery and flexible irrigation. The stator base 82 adopts a two-half symmetrical structure, with its inner wall curvature adapted to the outer wall of the flexible water pipe 6. During assembly, the two halves of the stator base 82 are respectively attached to the two sides of the pre-set installation position of the flexible water pipe 6, forming a complete annular clamping structure. Then, bolts passing through both sides of the stator base 82 are tightened to ensure that the stator base 82 is firmly clamped onto the flexible water pipe 6, guaranteeing connection reliability and avoiding damage to the pipe wall. Simultaneously, a pre-set water passage inside the stator base 82 precisely connects to the internal cavity of the flexible water pipe 6, providing a transmission path for the irrigation water flow.

[0040] The rotor 83 adopts an annular structure and is fitted onto the outside of the stator base 82. The two are connected by a precise fit to form a rotatable relationship. The rotational damping of the rotor 83 can be preset according to actual needs, ensuring that the angle can be flexibly adjusted and that it can maintain stable positioning at any angle. A dynamic rotating sealing ring assembly 84 is installed in the annular groove where the stator base 82 and the rotor 83 fit together. This sealing ring assembly adopts a multi-layer sealing structure and is tightly fitted to the inner wall of the groove and the inner wall of the rotor 83. During the relative rotation of the stator base 82 and the rotor 83, it always maintains a sealed state, effectively preventing water from leaking from the gap between the two. This forms a closed annular dynamic sealing water channel 85 between the stator base 82 and the rotor 83, realizing stable water transmission.

[0041] The sprinkler head 81 is fixedly connected to the rotor 83, and its water inlet is precisely aligned with the annular dynamic seal water channel 85. This ensures that the water flowing from the flexible water pipe 6 through the water passage of the stator seat 82 and the annular dynamic seal water channel 85 flows smoothly into the sprinkler head 81. Simultaneously, the sprinkler head 81 integrates an independent valve, which is integrally formed with the sprinkler head 81. By rotating the valve knob, the opening and closing of the sprinkler head 81 and the water flow rate can be directly controlled. This allows for individual adjustment of the sprinkler head 81's operating status based on the water requirements of different crops, soil moisture, and other factors, thus avoiding water waste.

[0042] Since the rotor 83 and stator base 82 are rotatably connected, and the sprinkler head 81 is fixed to the rotor 83, rotating the rotor 83 will drive the sprinkler head 81 to rotate synchronously, thus achieving flexible adjustment of the irrigation angle. During the adjustment process, the spray direction of the sprinkler head 81 can be adjusted vertically or rotated 360 degrees horizontally according to the needs of crop growth height, planting density, etc., so that the irrigation water can be precisely applied to the crop roots or leaf areas. This is suitable for crops such as wheat and corn that require large-area spraying, greatly improving irrigation adaptability and water resource utilization.

[0043] Furthermore, depending on the needs of the crop, such as planting strawberries or leafy vegetables, the sprinkler head 81 can be replaced with a drip arrow or drip irrigation tape.

[0044] Through the above structural design, the sprinkler assembly 8 achieves a stable connection with the flexible water pipe 6 and smooth water flow. The rotatable rotor 83, in conjunction with the sprinkler head 81, meets the angle adjustment requirements in different scenarios. The integrated independent valve gives the irrigation system refined control capabilities, while the dynamic rotating sealing ring assembly 84 ensures the reliability of the seal during rotation. The synergistic effect of each component makes the entire irrigation function flexible, efficient, stable, and durable, complementing the structural stability of the flexible water pipe 6 and further enhancing the comprehensive application benefits of "photovoltaics + agriculture".
