Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic equipment technology, specifically, it relates to a floating flexible photovoltaic support device. Background Technology

[0002] With the acceleration of the global energy transition, photovoltaic (PV) power generation, as a crucial clean energy solution, is expanding its application from land to water. Floating PV power plants, with their advantages of not occupying land resources and utilizing the cooling effect of water to improve power generation efficiency, have become an important development direction in the PV field. However, existing technologies still face the following core challenges in practical applications:

[0003] Traditional floating photovoltaic (PV) mounting systems often employ rigid connection structures (such as floats plus metal supports), which are prone to deformation or breakage under the impact of wind and waves, leading to damage to the PV modules. Furthermore, the fixed design of rigid supports is difficult to adapt to water surface fluctuations; prolonged swaying accelerates stress concentration at the connections, increasing maintenance costs. Existing supports often use fixed-angle designs, unable to dynamically adjust according to changes in solar position or water level, resulting in reduced solar panel efficiency. Some adjustable supports rely on complex mechanical structures, which are cumbersome to operate and have low reliability. When a single float or connector fails, traditional monolithic structures require disassembly of all components, making construction difficult and costly. In addition, the complex underwater operating environment further increases maintenance risks; current impacts and buoy misalignment can easily cause the PV panel mounting base to shift, affecting the overall system stability. Some designs improve stability by adding counterweights or anchoring devices, but at the expense of equipment flexibility and economy.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a floating flexible photovoltaic support device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A floating flexible photovoltaic support device includes: L-shaped steel, buoy, locking components, clamps, fixing angle iron, and fixing frame;

[0008] The inner frame of the fixed frame is designed with cross supports. There are four L-shaped steel sections, which are respectively set on the four sides of the fixed frame. Adjacent L-shaped steel sections are fixedly connected by fixed angle irons. The upper surface of the L-shaped steel section is provided with a sliding groove. The buoy is set directly below the L-shaped steel section. The top of the buoy is fixedly connected to a locking plate. The locking member slides and engages inside the locking plate. The locking head slides and engages inside the locking member. The top of the locking head is fixedly connected to a threaded rod. The threaded rod slides and engages with the sliding groove. The upper surface of the fixed frame is provided with an installation base plate for installing photovoltaic equipment.

[0009] Optionally, the surface of the fixed frame is provided with a limiting hole, and the lower surface of the mounting base plate is fixedly connected with a limiting bolt, the limiting bolt and the limiting hole being of the same type and specification.

[0010] Optionally, the lock is U-shaped, with a slot at the top, and the inner edge of the locking plate slidably engages with the slot.

[0011] Optionally, a fastening pressure plate is movably sleeved on the surface of the threaded rod, and a locking nut is rotatably connected to the top of the fastening pressure plate. The locking nut is threaded onto the surface of the threaded rod, and a rubber pad is fixedly connected to the bottom of the fastening pressure plate, and the rubber pad abuts against the top of the locking component and the top of the clamping plate.

[0012] Optionally, the threaded rod is threaded with a second locking nut and a third locking nut. The bottom end of the third locking nut abuts against the upper surface of the L-shaped steel, and the top end of the second locking nut abuts against the lower surface of the L-shaped steel.

[0013] Optionally, a lifting ring is fixedly connected to the side of the fixed angle iron, a traction rope is fixedly connected to the lifting ring, and a positioning anchor is fixedly connected to the bottom end of the traction rope.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] The L-shaped steel section design effectively enhances the structural bending stiffness, providing a stable support platform for the photovoltaic modules. The fixed frame utilizes an inner frame cross-bracing design to optimize stress distribution, disperse the load on the photovoltaic modules, and extend the overall structural lifespan. Fixed angle irons cross-connect the four L-shaped steel sections, forming a rigid frame that significantly improves the equipment's resistance to wind and waves. The buoy uses a buoyancy adjustment system to balance buoyancy distribution at different water depths, adapting to depth changes in complex hydrological environments. The top locking plate and U-shaped locking mechanism slide and engage, enabling rapid positioning and height adjustment while providing lateral limiting to prevent lateral displacement of the buoy. The locking head and locking mechanism work together to form a self-locking mechanism, effectively preventing displacement of the threaded rod due to wave impact. (Fastening...) The rubber pad at the bottom of the pressure plate increases friction with the locking components and clamping plate, preventing loosening of the threads and adapting to long-term use in dynamic environments. The double locking structure of locking nuts two and three abuts against the upper and lower surfaces of the L-shaped steel, respectively, achieving both height fine-tuning and enhanced shear resistance. In addition, the lifting rings on the side of the fixed angle iron are connected to the positioning anchors via traction ropes, forming a multi-point anchoring system that effectively suppresses the drift of the buoy cluster and improves structural stability under extreme weather conditions. The limiting bolts on the lower surface of the mounting base plate match the limiting holes of the fixing frame, ensuring accurate positioning of the mounting base plate and avoiding displacement caused by water flow impact. The coordinated action of all components ensures the reliability and practicality of the floating flexible photovoltaic support in different environments.

Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] Please see Figure 1-6 As shown, this embodiment provides a floating flexible photovoltaic support device, including: L-shaped steel 100, buoy 200, locking component 300, clamp 400, fixing angle iron 500 and fixing frame 600;

[0035] The inner frame of the fixed frame 600 is designed with cross supports. There are four L-shaped steel sections 100, which are respectively set on the four sides of the fixed frame 600. Adjacent L-shaped steel sections 100 are fixedly connected by fixed angle irons 500. The upper surface of the L-shaped steel section 100 is provided with a sliding groove 101. The float 200 is set directly below the L-shaped steel section 100. The top of the float 200 is fixedly connected to a card plate 201. The lock 300 is slidably engaged inside the card plate 201. The card head 400 is slidably engaged inside the lock 300. The top of the card head 400 is fixedly connected to a threaded rod 401. The threaded rod 401 is slidably engaged with the sliding groove 101. The upper surface of the fixed frame 600 is provided with an installation base plate 700 for installing photovoltaic equipment.

[0036] The L-shaped steel section 100, with its L-shaped cross-section design, enhances the structural bending stiffness and provides a stable support platform for the photovoltaic modules. The buoy 200 balances the overall buoyancy distribution, adapting to different water depths and improving equipment adaptability. The sliding locking mechanism 300 enables rapid positioning and height adjustment, facilitating precise alignment during photovoltaic module installation. The locking head 400, in conjunction with the locking mechanism 300, forms a self-locking mechanism to prevent the threaded rod 401 from shifting under wave impact, enhancing system stability. The fixed angle iron 500 cross-connects the four L-shaped steel sections 100 to form a rigid frame, improving the overall wind and wave resistance. The fixed frame 600, with its cross-bracing design, optimizes the stress distribution, disperses the load on the photovoltaic modules, and extends the structural lifespan.

[0037] like Figure 1-6 As shown, in this embodiment, the surface of the fixed frame 600 is provided with a limiting hole 601, and the lower surface of the mounting base plate 700 is fixedly connected with a limiting bolt 701. The limiting bolt 701 and the limiting hole 601 are of the same model and specification. The fit between the limiting bolt 701 and the limiting hole 601 is achieved through a matching plug-in design, ensuring accurate positioning of the mounting base plate 700 and preventing displacement caused by water flow impact.

[0038] like Figure 4-5 As shown, the lock 300 in this embodiment has a U-shaped design. The top of the lock 300 has a slot 301, and the inner edge of the locking plate 201 is slidably engaged with the slot 301. The sliding engagement between the slot 301 and the locking plate 201 simplifies the installation process and provides a lateral limiting function to prevent the float 200 from shifting laterally.

[0039] like Figure 5 As shown, in this embodiment, a fastening pressure plate 402 is movably sleeved on the surface of the threaded rod 401. A locking nut 403 is rotatably connected to the top of the fastening pressure plate 402. The locking nut 403 is threaded onto the surface of the threaded rod 401. A rubber pad is fixedly connected to the bottom of the fastening pressure plate 402, and the rubber pad abuts against the top of the locking member 300 and the top of the clamping plate 201. By increasing the friction between the locking nut and the locking member 300, loosening of the threads is prevented, making it suitable for long-term use in dynamic hydrological environments.

[0040] like Figure 1-5 As shown, in this embodiment, the threaded rod 401 is threaded with a second locking nut 404 and a third locking nut 405. The bottom end of the third locking nut 405 abuts against the upper surface of the L-shaped steel 100, and the top end of the second locking nut 404 abuts against the lower surface of the L-shaped steel 100. Through the double locking mechanism of the second locking nut 404 and the third locking nut 405, the upper and lower surfaces of the L-shaped steel 100 are fixed respectively, achieving height fine-tuning and shear resistance reinforcement.

[0041] like Figure 1-3As shown, in this embodiment, a lifting ring 501 is fixedly connected to the side of the fixed angle iron 500, a traction rope 502 is fixedly connected to the lifting ring 501, and a positioning anchor 503 is fixedly connected to the bottom end of the traction rope 502. The lifting ring 501 and the positioning anchor 503 form a multi-point anchoring through the traction rope 502, which effectively suppresses the drift of the buoy cluster 200 and improves the structural stability under extreme weather conditions.
