Description

Technical Field

[0001] This utility model relates to the field of floating photovoltaic power generation technology, and in particular to a detachable floating photovoltaic power station. Background Technology

[0002] Floating photovoltaic (PV) systems are a renewable energy generation technology that installs photovoltaic modules on the water surface. The system uses pontoons or floating frames to support the PV panels, effectively utilizing water space and reducing land occupation. The floating design reduces the temperature of the PV modules, improving power generation efficiency while minimizing water evaporation and algae growth. Suitable for reservoirs, lakes, offshore areas, and industrial pools, this system offers advantages such as environmental friendliness, energy conservation, and emission reduction, and is gradually becoming an important development direction for global photovoltaic power generation.

[0003] Common classifications of floating photovoltaic systems can be based on structural characteristics (rigid, flexible, and hybrid rigid-flexible floating bodies), applicable water areas (inland still water, nearshore shallow water, and deep sea), anchoring methods (pile foundation fixing, multi-point mooring, and dynamic tension), and functional integration (single power generation, multi-energy complementarity, and ecological integration) to adapt to different environments and needs. Among them, rigid floating bodies dominate nearshore areas, flexible systems break through deep sea areas, and multi-energy synergy and intelligent anchoring are the future trends.

[0004] However, the floating bodies used in current photovoltaic floating power stations have high transportation and storage costs. Due to the large size of the existing floating bodies, the space utilization rate during transportation is low, resulting in a significant increase in logistics costs. Moreover, during storage, the floating bodies are difficult to stack and require a large area of ​​space.

[0005] Therefore, there is an urgent need for a detachable photovoltaic floating power station that is not only easy to install and dismantle, but also allows the floating bodies to be stacked for storage or transportation. Utility Model Content

[0031] 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.

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1-10 This utility model discloses a detachable photovoltaic floating power station, including multiple floating components 1 arranged in parallel with each other. Multiple photovoltaic components 3 are arranged between two adjacent floating components 1. Each photovoltaic component 3 is arranged between two adjacent floating components 1 through multiple support components 2. The photovoltaic component 3 (also known as a solar panel) is the core component of the solar power generation system, responsible for directly converting solar energy into electrical energy. The photovoltaic component 3 includes battery cells, interconnecting strips, busbars, junction boxes, glass back panels, cables, frames, sealant, back panels, frames, etc.

[0034] Floating Component 1 is a floating platform supporting Photovoltaic Component 3. It mainly adopts a modular design of high-density polyethylene (HDPE) or composite materials, forming an array through rigid / flexible connections. Its core characteristics include: environmental resistance: it must meet the requirements of wind and wave resistance (wave height ≥ 1.5 meters), salt spray corrosion resistance, and prevention of biofouling; structural adaptability: in shallow water areas, the floating pontoons are fixed with pile foundations, while in deep water areas, flexible floating bodies + dynamic anchoring (such as tension legs) are used; economic and ecological balance: HDPE floating bodies are low in cost but have a short lifespan (about 15 years), while steel floating bodies are durable (30 years) but cost 30% more and require a coating to prevent pollution; functional integration: some floating bodies integrate cleaning channels or ecological bases.

[0035] The floating assembly 1 includes multiple floating bodies, and two adjacent floating bodies are detachably connected. Each floating body includes an upper floating body 11, and the upper floating body 11 is detachably connected to a lower floating body 14 via multiple snap-fit ​​parts 17. The top surface of the upper floating body 11 is detachably connected to the support assembly 2. The snap-fit ​​parts 17 adopt mortise and tenon joints or elastic buckles.

[0036] The floating body is made of high-density polyethylene (HDPE) or other polymers, featuring low density, corrosion resistance, UV resistance, and environmental friendliness. The floating body employs a pontoon structure, allowing for flexible size adjustment based on water depth and level changes.

[0037] The floating body adopts a split structure design of upper floating body 11 and lower floating body 14, and achieves rapid assembly and disassembly through standardized interfaces (such as mortise and tenon joints or elastic buckles), which significantly optimizes transportation and installation efficiency.

[0038] Multiple upper floating bodies 11 and multiple lower floating bodies 14 can be stacked during storage and transportation.

[0039] By stacking the upper float 11 and the lower float 14, transportation costs can be reduced and space can be compressed. After stacking, the volume of the upper float 11 and the lower float 14 is reduced by more than 40%, and high-density stacked transportation is supported, reducing logistics costs by 30%.

[0040] The upper float 11 and the lower float 14 are made of HDPE material, which allows the decommissioned upper float 11 and lower float 14 to be disassembled and recycled separately. The HDPE material has a recycling rate of 95%, reducing the environmental impact and achieving ecologically compatible maintenance.

[0041] Taking a 10MW floating power station as an example, multiple upper floats 11 and multiple lower floats 14 are stacked vertically to form standard modules of 2m×1.5m. This reduces the transportation space of the stacked standard modules by 45% compared to traditional integrated floats. During installation, the modules are connected by bidirectional locking pins with limit function, allowing for ±8mm deformation displacement. The lower floats 14 are filled with flame-retardant EPS foam (oxygen index ≥32) and a leakage sensor is integrated to enable rapid location and replacement of faulty units.

[0042] The photovoltaic module 3 of this utility model is installed on the floating module 1 through the support module 2, which facilitates on-site installation and disassembly. At the same time, the upper floating body 11 and the lower floating body 14 are detachably connected by multiple snap-fit ​​parts 17, so that multiple upper floating bodies 11 and multiple lower floating bodies 14 can be stacked during storage and transportation, which not only improves the space utilization during transportation, but also effectively reduces the floor space occupied during storage.

[0043] In a further optimized design, a first positioning groove 12 is symmetrically provided at the end of the upper float 11 away from the lower float 14, and a first limiting groove 13 is provided on the top surface of the first positioning groove 12 for limiting the support component 2. This allows the support component 2 to be effectively installed in the first limiting groove 13.

[0044] In a further optimized design, the depth of the first positioning groove 12 is greater than the thickness of the upper float 11. This allows one end of the first positioning groove 12 extending out of the bottom of the upper float 11 to protrude from the bottom of the upper float 11, and the end of the upper positioning groove 12 protruding from the bottom of the upper float 11 to be inserted into the lower positioning groove 12, enabling multiple upper floats 11 to be effectively stacked.

[0045] To further optimize the design, a second limiting groove 15 is provided on the top surface of the lower float 14, and a positioning post 16 is fixedly connected to the bottom surface of the lower float 14. The positioning post 16 penetrates the bottom surface of the lower float 14 and extends into the second limiting groove 15.

[0046] The second limiting groove 15 is filled with a cushioning material, which is a lightweight material with a certain cushioning capacity, such as EPS foam. After the lower float 14 is installed in the designated position and before the upper float 11 is installed, the cushioning material is filled into the second limiting groove 15 in the lower float 14; after the upper float 11 is installed on the lower float 14, the upper float 11, the lower float 14 and the cushioning material form a whole.

[0047] In a further optimized design, a third limiting groove is provided at one end of the positioning post 16 on the bottom surface of the lower float 14. By inserting the lower positioning post 16 into the third limiting groove at the bottom of the upper positioning post 16, multiple lower floats 14 can be effectively stacked.

[0048] The design is further optimized by positioning the end of the positioning post 16 flush with the bottom surface of the lower float 14. This ensures that the bottom surface of the lower float 14 is flush, allowing the lower float 14 at the bottom to remain stable in a horizontal position without swaying, and enabling the lower floats 14 to be effectively stacked.

[0049] The design is further optimized so that the distance between the end of the positioning post 16 that extends into the second limiting groove 15 and the top surface of the lower float 14 is matched with the length of the first positioning groove 12 extending out of the bottom surface of the upper float 11. This allows the upper lower float 14 to be effectively stacked on top of the lower lower float 14.

[0050] The design was further optimized so that both the positioning post 16 and the third limiting groove are tapered. This allows the positioning post 16 to effectively extend into the third limiting groove.

[0051] Connecting plates are fixedly connected to both ends of the lower float 14. The two connecting plates are staggered vertically so that the two connecting plates on opposite sides of the two adjacent lower floats 14 can be effectively staggered vertically, and the two connecting plates are connected by multiple first bolts.

[0052] Further optimizing the design, the support component 2 includes a crossbeam 21. One end of the crossbeam 21 extends into the first limiting groove 13 and is detachably connected to the first limiting groove 13. A front bracket 22 is symmetrically arranged on the top surface of the crossbeam 21, and the front bracket 22 is detachably connected to the photovoltaic module 3. The crossbeam 21 is installed in the first limiting groove 13 by multiple second bolts; and the front bracket 22 facilitates the installation and removal of the photovoltaic module 3.

[0053] The crossbeam 21 is made of metal rods or non-metallic polymer rods.

[0054] In a further optimized design, the photovoltaic module 3 includes symmetrically arranged photovoltaic panels 31. The opposite ends of the two photovoltaic panels 31 are connected by multiple intermediate supports 32, and the end of the photovoltaic panel 31 away from the intermediate supports 32 is detachably connected to the front support 22. The two photovoltaic panels 31 are arranged at an angle, with the opposite ends of the two photovoltaic panels 31 at a higher position.

[0055] The front bracket 22 has a first through hole 23 at one end facing the photovoltaic panel 31. A second bolt is installed in the first through hole 23. The photovoltaic panel 31 is installed on the front bracket 22 by passing the second bolt through the first through hole 23.

[0056] The front bracket 22 has multiple second through holes 24 at one end facing the crossbeam 21. A third bolt is installed in the second through hole 24. The front bracket 22 is installed on the crossbeam 21 by passing the third bolt through the second through hole 24.

[0057] The central support 32 is set in an I-shape. The two wing plates on both sides of the central support 32 are adapted to the tilt angle of the photovoltaic panel 31, so that the photovoltaic panel 31 can be effectively positioned between the two wing plates on the same side. A third through hole 33 is opened on the lower wing plate. A fourth bolt is installed in the third through hole 33. The photovoltaic panel 31 is installed between the two wing plates on the same side by passing through the third through hole with the fourth bolt.

[0058] Work process:

[0059] By stacking multiple upper floats 11 and multiple lower floats 14 one on top of the other, transportation can be carried out effectively.

[0060] At the installation site, a modular assembly platform is built and the floating component 1 is pre-assembled. A modular lifting platform is built in the shallow water area near the shore to assemble the floating body. Buffer material is filled into the second limiting groove 15, and then the upper floating body 11 is installed on the lower floating body 14.

[0061] The support component 2 and photovoltaic component 3 are installed in a coordinated manner, and the installation is assisted by a robot. The installation sequence is as follows: the two ends of the crossbeam 21 are respectively installed in the first limiting groove 13 of the two upper floating bodies 11 by the second bolts, and then the front bracket 22 is installed on the crossbeam 21 by the third bolt through the second through hole 24. Then the photovoltaic panel 31 is installed on the front bracket 22 by the second bolt through the first through hole 23, and then the photovoltaic panel 31 is installed between the two wing plates on the same side by the fourth bolt through the third through hole.

[0062] Inverter and cable integration deployment:

[0063] The installation sequence of the floating moisture-proof chamber and the self-floating cable system is as follows: floating moisture-proof sealing -> inverter installation -> cable pre-insertion into segmented HDPE buoyancy pipe -> cable laying.

[0064] This invention facilitates installation and transportation by disassembling the various components, and effectively improves the utilization rate of transportation space by stacking the upper float 11 and the lower float 14 respectively.

[0065] It can be installed in the forward direction as a photovoltaic float, or in the reverse direction as a ship.

[0066] The present invention features stress control and ease of installation. Flexible buffer gaps (such as EPDM rubber pads) are reserved between modules to eliminate residual assembly stress. After pre-assembly on shore, the whole unit is towed to the water, shortening the installation cycle by 50%.

[0067] The innovative design for damage resistance and safety features an independent sealed compartment structure for the second limiting groove 15 of each floating body. Damage to a single compartment only results in localized failure, mitigating the risk of overall sinking. Key load-bearing areas incorporate closed-cell EPS foam core material (density ≥ 15 kg / m³). 3 It provides redundant buoyancy and enhances impact resistance, with a buoyancy loss rate of <5% after damage.

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
