Description

Technical Field

[0001] The present invention relates to a field of floating photovoltaic platforms, and in particular to a floating body assembly. Background Art

[0002] As an emerging solar power generation platform, floating offshore photovoltaic platforms hold enormous development potential, leveraging the vast ocean's vast expanse and abundant sunlight resources. However, due to the complex and volatile marine environment, existing, mature floating photovoltaic technologies developed for inland waters struggle to operate reliably in this environment. The key bottleneck hindering the further development of floating offshore photovoltaic technology lies in effectively reducing the construction costs of the float and mooring system while ensuring long-term operational reliability at sea. Due to these limitations, commercialization of floating offshore photovoltaics has yet to be achieved.

[0003] Existing floating offshore photovoltaic platforms primarily include semi-submersible offshore photovoltaic platforms based on buoy foundations, buoy array offshore photovoltaic platforms, multi-buoy offshore photovoltaic platforms, floating platforms with separate floats and supports, and hexagonal floating platforms. The first types of platforms with buoy foundations have buoys as their floating foundations; floating platforms with separate floats and supports have frame-like foundations, while hexagonal floating platforms have lattice-like structures.

[0004] Floating offshore photovoltaic platforms face significant challenges in wind and wave resistance. Current pontoon, frame, and lattice structures lack wave-dissipation design, which negatively impacts the platform's overall wind and wave resistance. Furthermore, these structures, including pontoon, frame, and lattice structures, comprise a variety of different components, making assembly and installation at sea cumbersome and limiting flexible reconfiguration, hindering mass production and commercialization.

[0005] Therefore, it is necessary to develop a new type of floating offshore photovoltaic platform floating body module in a targeted manner to overcome the problems of poor wind and wave resistance, inability to mass produce and flexible reconstruction in existing technologies. Summary of the Invention

[0006] Purpose of the invention: In response to the shortcomings and defects of the existing technology, the present invention provides a floating body module of a floating offshore photovoltaic platform. By optimizing the structural design, the module has the function of wave absorption and flow diversion, which can improve the platform's wind and wave resistance and ensure the stable operation of the platform in a complex marine environment. The specifications and shapes are unified and can be made into standard parts. A set of molds is used for mass production, which can reduce the difficulty of offshore construction and realize flexible reconstruction of the platform.

[0007] Technical solution: A floating offshore photovoltaic platform buoyancy module of the present invention is characterized in that it includes a wave-breaking opening, a horizontal guide groove, a connecting groove, a pin hole and a vertical guide hole; the wave-breaking opening and the horizontal guide groove are occasionally arranged in the length direction and width direction of the module, covering the entire length and width direction, and the middle part of the bottom of the module is concave as a whole; the four sides of the module are provided with connecting grooves, the pin hole is located above the connecting groove, and the vertical guide hole is arranged in the concave position in the middle of the bottom of the module.

[0008] Wherein, the assembly block is an integrally formed casting.

[0009] The block is a rectangular parallelepiped structure, which is an axisymmetric structure in two directions.

[0010] Wherein, a wave-breaking opening is provided in the horizontal direction at the bottom of the block, and a vertical guide hole is provided vertically in the middle of the block.

[0011] The connecting slots are symmetrically arranged, and are slotted inwardly on the four sides of the module for installing connecting pieces between modules.

[0012] Wherein, the pin hole is used to fix the assembly block to the connecting piece.

[0013] The pin holes are arranged in groups of two, extending from the slotted surface to the upper surface of the block, and are used for installing the pins when the blocks are connected.

[0014] Wherein, the diameter of the vertical guide hole close to the inner concave surface of the bottom of the block is larger than the diameter close to the top of the block.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages:

[0016] The wind and wave resistance of the present invention is improved: this technical solution sets wave-breaking openings and guide grooves in the horizontal direction of the module, and sets a bottom concave design and guide holes in the vertical direction, which can effectively improve the wind and wave resistance of the module. The floating foundation assembled using this module technical solution will also have a higher wind and wave resistance.

[0017] The present invention facilitates mass production: This technical solution has a regular structure and can be molded in one go using a casting method. When the product is actually supplied, if there is a demand for mass production, the same set of molds can be used to achieve mass production. Due to the structural symmetry, the mass production process has a high fault tolerance rate and a simple process.

[0018] This invention facilitates offshore installation: The modules are connected by connectors and pins, making disassembly easy. The modules can be assembled into partial modules of a floating offshore photovoltaic platform. The modules are then connected using the same connectors and pins, allowing for flexible assembly into floating photovoltaic platforms of varying sizes and shapes. When the platform needs to be disassembled, it can be flexibly disassembled into its modules by releasing the pins, facilitating repair, replacement, and emergency response.

[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The floating body module of the floating offshore photovoltaic platform of the present invention is formed by an integrated molding process and is a casting. The module is a rectangular parallelepiped structure as a whole, and has axial symmetry in two directions. A wave-breaking and diversion opening is designed in the horizontal direction at the bottom of the module, and a diversion hole is designed in the vertical direction in the middle of the module, which can effectively reduce the hydrodynamic force borne by the module and enhance the wind and wave resistance. The module is grooved inward on the four sides, with a total of 8 grooves, which are symmetrically arranged. At the slot position, the module has 2 holes, which pass through from the slot surface to the upper surface of the module, and are used to install pins when connecting the modules.

[0026] like Figure 1-4 The floating offshore photovoltaic platform module structure includes a wave-breaking opening 1, a horizontal guide groove 2, a connection slot 3, a pin hole 4, and a vertical guide hole 5. The middle part of the bottom of the module is concave as a whole. Figure 4 . The wave-breaking opening 1 and the horizontal guide groove 2 are occasionally arranged in the length direction and the width direction of the module, covering the entire length and width direction. The connecting slots 3 are slotted inward on the four sides of the module and are symmetrically arranged for the installation of connectors between modules. The pin hole 4 is connected above the slot 3 and is used to fix the module and the connector. The vertical guide hole 5 is set in the concave position in the middle of the bottom of the module. The diameter is larger near the concave surface of the bottom of the module, and the diameter is smaller near the top of the module.

[0027] The modules of this invention feature horizontal wave-absorbing openings and diversion grooves at their bases. The modules also feature indentations and vertical diversion holes at their bases, effectively buffering current and wave loads. The modules are symmetrical in length and width, creating a nearly rectangular, regular shape. In particular, the symmetrical slots for connectors along the length and width facilitate mass production and flexible assembly and disassembly at sea.

[0028] The wind and wave resistance of the present invention is improved: this technical solution sets wave-breaking openings and guide grooves in the horizontal direction of the module, and sets a bottom concave design and guide holes in the vertical direction, which can effectively improve the wind and wave resistance of the module. The floating foundation assembled using this module technical solution will also have a higher wind and wave resistance.

[0029] The present invention facilitates mass production: This technical solution has a regular structure and can be molded in one go using a casting method. When the product is actually supplied, if there is a demand for mass production, the same set of molds can be used to achieve mass production. Due to the structural symmetry, the mass production process has a high fault tolerance rate and a simple process.

[0030] This invention facilitates offshore installation: The modules are connected by connectors and pins, making disassembly easy. The modules can be assembled into partial modules of a floating offshore photovoltaic platform. The modules are then connected using the same connectors and pins, allowing for flexible assembly into floating photovoltaic platforms of varying sizes and shapes. When the platform needs to be disassembled, it can be flexibly disassembled into its modules by releasing the pins, facilitating repair, replacement, and emergency response.
