[0035] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following is combined Figures 1 to 4 This invention describes a raft-type marine integrated platform 1000 with built-in photovoltaic power generation and wave power generation according to an embodiment of the present invention.

[0037] like Figure 1 As shown, the raft-type marine integrated platform 1000 with photovoltaic power generation and wave power generation according to an embodiment of the present invention includes multiple bamboo raft-type floating structural units 1, solar panels 2, and wave power generation devices 3. The multiple bamboo raft-type floating structural units 1 are arranged sequentially along the longitudinal direction. The solar panels 2 are mounted on the top of at least one of the multiple bamboo raft-type floating structural units 1 via supports. The wave power generation devices 3 are disposed between longitudinally adjacent bamboo raft-type floating structural units 1. The wave power generation devices 3 include hinged supports 301 and hydraulic power output devices 302. The ends of the longitudinally adjacent bamboo raft-type floating structural units 1 that are close to each other are rotatably connected by hinged supports 301. The hydraulic power output devices 302 are disposed on the top of the longitudinally adjacent bamboo raft-type floating structural units 1.

[0038] It is understood that at least two bamboo raft-type floating structure units 1 are provided. Solar panels 2 are mounted on top of at least one of the multiple bamboo raft-type floating structure units 1 via brackets; it is understood that the arrangement position and number of solar panels 2 can be set according to actual conditions, and solar panels 2 can generate electricity using solar energy to achieve self-sufficiency of the electrical energy required by the raft-type marine integrated platform 1000 of the present invention.

[0039] The wave energy generation device 3 is installed between the longitudinally adjacent bamboo raft-type floating structure units 1. Firstly, the wave energy generation device 3 can generate electricity using the wave response of the raft-type marine integrated platform 1000 of the present invention, thereby achieving self-sufficiency in the electrical energy required by the raft-type marine integrated platform 1000. Secondly, since the wave energy generation device 3 consumes energy during the power generation process, it can act as a damper, reducing the wave dynamic response of the raft-type marine integrated platform 1000, i.e., reducing the vertical motion amplitude of the bamboo raft-type floating structure unit 1 under wave load, thereby improving the stability and comfort of the raft-type marine integrated platform 1000. Finally, since the wave energy generation device 3 connected between the longitudinally adjacent bamboo raft-type floating structure units 1 can deform under wave load, it also helps to reduce the stress level of the raft-type marine integrated platform 1000.

[0040] like Figure 2 As shown, the wave energy power generation device 3 includes a hinged support 301 and a hydraulic power output device 302. The ends of the longitudinally adjacent bamboo raft-type floating structure units 1 are rotatably connected by the hinged support 301, and the hydraulic power output device 302 is disposed on the top of the longitudinally adjacent bamboo raft-type floating structure units 1. It can be understood that the hinged support 301 restricts the longitudinal displacement of the longitudinally adjacent bamboo raft-type floating structure units 1, so that the bamboo raft-type floating structure units 1 can only rotate relative to each other. When the bamboo raft-type floating structure units 1 rotate repeatedly relative to each other under the action of waves, the bamboo raft-type floating structure units 1 will drive the hydraulic power output device 302 to repeatedly extend and retract, thereby realizing the conversion of wave energy into electrical energy, and thus enabling the raft-type marine integrated platform 1000 of the present invention to achieve partial or complete self-sufficiency in electrical energy.

[0041] According to an embodiment of the present invention, the raft-type marine integrated platform 1000 with self-contained photovoltaic power generation and wave power generation, by setting solar panels 2 on the bamboo raft-type floating structure unit 1 and by setting wave power generation devices 3 between longitudinally adjacent bamboo raft-type floating structure units 1, on the one hand, the electricity generated by the wave power generation device 3 and the solar panels 2 can solve the power supply problem of the raft-type marine integrated platform 1000 of the present invention, realizing self-supply of electricity; on the other hand, the wave power generation device 3 can reduce the wave dynamic response of the raft-type marine integrated platform 1000 of the present invention through damping effect, thereby improving the stability and comfort of the raft-type marine integrated platform 1000 of the present invention, and also helping to reduce the stress level of the raft-type marine integrated platform 1000 of the present invention.

[0042] According to some embodiments of the present invention, each bamboo raft-type floating structure unit 1 includes multiple floating units 101 and multiple connecting beams 102. The multiple floating units 101 are arranged side by side in the horizontal plane and connected together by the multiple horizontally extending connecting beams 102. In this way, the formed bamboo raft-type floating structure unit 1 has the characteristics of modularity, scalability, and convenient transportation, and is highly practical.

[0043] In some embodiments, such as Figure 4 As shown, multiple connecting beams 102 are provided with multiple through holes 103 spaced apart in the transverse direction, and multiple floating units 101 are correspondingly inserted into the multiple through holes 103 on the multiple connecting beams 102. This facilitates assembly and provides a good connection effect when connecting multiple floating units 101.

[0044] Optionally, multiple connecting beams 102 extend in the transverse direction and are spaced apart in the longitudinal direction.

[0045] According to some embodiments of the present invention, such as Figure 1 As shown, each solar panel 2 is fixed to a single floating unit 101, and the width of the single solar panel 2 is smaller than the lateral dimension of the single floating unit 101. This ensures that even if adjacent floating units 101 sway or loosen, or if the distance between adjacent floating units 101 increases or decreases, the solar panel 2 will not experience stress, and there will be no collision between adjacent floating units 101, thus preventing any impact on the solar panel 2 and ensuring its long-term stable and normal operation.

[0046] According to some embodiments of the present invention, such as Figure 2As shown, the hydraulic power output device 302 includes a generator 3021, a piston 3022, and a connecting rod 3023. The generator 3021 is fixed to one of the longitudinally adjacent raft-type floating structure units 1. The piston 3022 is reciprocally connected to the generator 3021 relative to it. One end of the connecting rod 3023 is hinged to the piston 3022, and the other end of the connecting rod 3023 is hinged to the other longitudinally adjacent raft-type floating structure unit 1. It can be understood that, under the constraint of the hinged support 301, when the two raft-type floating structure units 1 rotate relative to each other under wave load, because the other end of the connecting rod 3023 is hinged to the raft-type floating structure unit 1, and the piston 3022 is hinged to one end of the connecting rod 3023, the connecting rod 3023 will drive the piston 3022 to reciprocate relative to the generator 3021 in the longitudinal direction, thereby converting wave energy into electrical energy. Specifically, the hinge axis between the hinge support 301, one end of the connecting rod 3023 and the piston 3022, and the hinge axis between the other end of the connecting rod 3023 and the raft-type floating structure unit 1 are all parallel to each other and extend laterally.

[0047] Optionally, such as Figure 2 As shown, the generator 3021 is fixed to the connecting beam 102 or floating unit 101 of one of the raft-type floating structure units 1, and the other end of the connecting rod 3023 is hinged to the connecting beam 102 or floating unit 101 of the other raft-type floating structure unit 1, which can be selected according to the actual situation. It should be noted that the hinged support 301 is connected between the ends of the two longitudinally spaced floating units 101.

[0048] According to some embodiments of the present invention, generator 3021 is a reciprocating generator.

[0049] According to some embodiments of the present invention, such as Figure 3 As shown, each floating unit 101 includes N cylinders 1011 and floating tubes 1012. The N cylinders 1011 are spliced ​​longitudinally to form a tube, where N ≥ 2. The floating tubes 1012 are disposed in the cavity of the tube. The tube formed by the N cylinders 1011 mainly serves as a load-bearing structure and is the main body. The N cylinders 1011 are spliced ​​axially in sequence to form the tube, where N ≥ 2. That is to say, the tube is formed by at least two cylinders 1011 spliced ​​axially in sequence. In practice, the number of cylinders 1011 spliced ​​axially in sequence can be determined according to the required length of the tube. Using splicing connection makes it more convenient to disassemble and replace the cylinders 1011.

[0050] According to some embodiments of the present invention, the floating pipe 1012 is a corrugated pipe sealed at both ends. Because the corrugated pipe is expandable and contractible, it facilitates production and construction, significantly reducing construction difficulty and cost.

[0051] According to some embodiments of the present invention, circuits and pipelines are laid inside the cylinder 1011. By laying circuits and pipelines inside the cylinder, the daily use needs of the raft-type marine integrated platform 1000 of the present invention can be met; on the other hand, it is also more aesthetically pleasing.

[0052] Optionally, multiple fasteners are pre-embedded on the outer surface of the cylinder 1011. It should be noted that these multiple fasteners are used for the installation of non-structural components and the mooring system. For example, the fasteners can be rivets.

[0053] Optionally, such as Figure 3 As shown, each cylinder 1011 has tongue and groove joints at both ends, and adjacent cylinders 1011 are spliced ​​together through the tongue and groove joints, which facilitates quick assembly and installation between two adjacent cylinders 1011.

[0054] According to some embodiments of the present invention, the cylinder 1011 is a concrete cylinder, which is a precast concrete component, and the pipe is a concrete pipe; the floating unit 101 further includes a carbon fiber plate 1013, which is axially inserted into the cavity of the concrete pipe and located between the concrete pipe and the floating pipe component 1012. The two ends of the carbon fiber plate 1013 are respectively fixed to the two ends of the concrete pipe after prestressing. The concrete pipe is reinforced with FRP bars. Thus, the floating unit 101 has a long service life, good corrosion resistance, and good floating effect.

[0055] In this embodiment, the bamboo raft-type floating structure unit 1 is assembled as follows: First, the corresponding concrete cylinders are assembled with the connecting beams 102, and then the corresponding concrete cylinders are assembled with each other. Next, several carbon fiber plates 1013 are arranged circumferentially along the inner wall of the concrete tubes. Tensioning the carbon fiber plates 1013 applies a pre-tightening force to the carbon fiber plates 1013 and the N concrete cylinders to secure them. Finally, a corrugated pipe is placed inside the concrete tubes, and other components are installed on the concrete tubes or connecting beams 102 as needed. The assembled bamboo raft-type floating structure unit 1 is then floated afloat and towed to a predetermined sea area by a vessel. After installing a mooring system, it is ready for service.

[0056] It's important to clarify that FRP stands for Fiber Reinforced Polymer, a high-performance material using carbon fiber, glass fiber, or other reinforcing agents and polymer resin as the matrix. It features resistance to seawater corrosion, lightweight yet high strength, and high design flexibility. Replacing the reinforcement in a concrete cylinder with FRP bars can effectively solve the problem of reinforced concrete structures still corroding and having a short service life in the ocean, significantly extending the lifespan of the concrete cylinder and reducing maintenance costs. Specifically, FRP bars can be made of glass fiber, basalt fiber, or carbon fiber.

[0057] The concrete cylinder is a precast concrete component, meaning it is manufactured in a factory and then transported to the assembly location for assembly. This improves construction efficiency and ensures good dimensional uniformity and quality for the precast concrete cylinder.

[0058] The raft-type floating structure unit 1 of this embodiment has the following advantages: First, since the concrete cylinder, floating pipe 1012, and carbon fiber plate 1013 all have excellent corrosion resistance and superior durability, the raft-type marine integrated platform 1000 of this invention has the advantage of long service life and can be used normally for a long time; Second, since the two ends of the carbon fiber plate 1013 are respectively fixed to the two ends of the concrete pipe after prestressing, the carbon fiber plate 1013 and the concrete cylinder can bear the load simultaneously, resulting in greater load-bearing strength and higher load-bearing capacity. It can be used as a load-bearing component of marine facilities, and the concrete pipe... Third, this invention adopts a tubular prefabrication and assembly construction scheme. The prefabricated concrete cylinder is assembled on-site, and can be put into service after the mooring system is installed. The structure is simple, easy to assemble, and has low construction and maintenance costs, making it well-suited for use in marine environments with poor maintenance capabilities. Fourth, due to the modular and splicing design of this invention, the floating unit 101 can be easily and quickly disassembled. When the floating unit 101 reaches its service life or is partially damaged, it can be towed back to the dock for segmented disassembly and recycling, further reducing usage costs. Therefore, the bamboo raft-type floating structure unit 1 of this embodiment has advantages such as high production efficiency, fast installation speed, modularity, scalability, and recyclability.

[0059] In a specific example, such as Figure 4 As shown, the connecting beam 102 is a long strip with a square longitudinal section. Circular holes are evenly arranged on the side of the connecting beam 102. The concrete cylinder is a circular tube. The diameter of the circular holes on the connecting beam 102 is slightly larger than the outer diameter of the concrete cylinder.

[0060] Optionally, the carbon fiber sheet 1013 is manufactured by pultrusion or vacuum induction manufacturing process. The resulting carbon fiber sheet 1013 has the advantages of high elastic modulus, high strength and corrosion resistance, and has good performance.

[0061] Optionally, the concrete cylinder can be made of lightweight aggregate concrete or fiber-reinforced lightweight aggregate concrete. This ensures both the strength of the concrete cylinder and its lightness, which is beneficial for optimizing the floating effect of the raft-type marine integrated platform 1000 of this invention.

[0062] Optionally, the cylinder 1011 is a steel cylinder, and N steel cylinders are sequentially spliced ​​axially by welding or bolting to form a steel pipe. It is understood that the steel cylinders are all treated for corrosion resistance.
