[0002] In recent years, with the rapid development of the photovoltaic industry, large-scale photovoltaic power stations have grown rapidly, especially water photovoltaic power stations, which are particularly suitable for coal mining subsidence areas, drinking water reservoirs, hydropower reservoirs, offshore waters, and various regions such as inner lakes. They have been widely recognized in terms of safety and environmental protection and have become an important development direction for the future of the photovoltaic industry.

[0003] Currently, water photovoltaic power stations are generally built on floating photovoltaic platforms. The floating body platform is assembled from multiple floating bodies, wherein the floating bodies are mainly formed by integrated blow molding process to form a hollow structure that can provide buoyancy to components such as modules on the platform. The average wall thickness of the floating body is relatively thin. However, in some special water quality, aquatic organisms in the water can cause the floating body to leak air by secreting corrosive substances and "gnawing", thereby losing buoyancy and losing the function of the floating body structure.

[0004] In view of the above, how to solve the problem of the floating body easily leaking air and losing its function has become a technical problem that needs to be solved by those skilled in the art. Practical new type content

[0059] The core of this application is to provide a floating body, a floating photovoltaic platform, and a photovoltaic power station for waterborne photovoltaics, in order to solve the problem that the floating body is prone to air leakage and loses its floating function.

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0061] Reference Figures 1-9 As shown, one embodiment of this application provides a float 1 for floating photovoltaics, which specifically includes a float shell 11 and a float body 12. The float shell 11 has a loading cavity 110 formed inside. The float body 12 is a float structure made of lightweight plastic. The float body 12 is disposed in the loading cavity 110, and the outer wall of the float body 12 fits snugly with the inner wall of the loading cavity 110, thereby ensuring the stability of the installation between the float body 10 and the float shell 11.

[0062] In practical applications, the float 1 used for floating photovoltaics is made of lightweight plastic through molding. The float body 12 is located in the loading cavity 110 of the float shell 11. The outer wall of the float body 12 fits snugly with the inner wall of the loading cavity 110. Therefore, the float shell 11 provides a protective enclosure for the float body 12, preventing direct contact between the float body 12 and corrosive substances secreted by aquatic organisms. It also prevents aquatic organisms from directly biting the float body 12, effectively ensuring the buoyancy function of the float body 12.

[0063] It is worth mentioning that the main body 12 of the float can be a filled float structure made of lightweight plastic, such as foam plastic, lightweight low-density plastic, or a structure with multiple densely packed small closed cavities, as long as it can form a lightweight low-density filled float. The processing method of the filled float structure can be, but is not limited to, molding, cutting and other forming processes. By designing the main body 12 of the float into the form of the above-mentioned filled float structure, even if the outer shell 11 of the float is corroded or torn to form a hole, the main body 12 of the float will still be intact. In fact, even if the main body 12 of the float is also corroded or torn, since the filled float structure is different from the hollow float structure, there is no need to worry about air or water leakage. Even if the filled float structure is corroded or torn to form a gap, it can still maintain the function of providing buoyancy.

[0064] It is understandable that the main body 12 of the float can also be a hollow float structure made of lightweight plastic. The hollow float structure is another structural form that is the opposite of the filled float structure. The hollow float structure can be made by processes such as blow molding, but is not limited to blow molding. Compared with the existing technology, when the first line of defense, the outer shell 11 of the float, is corroded or torn and perforated, the wall thickness of the hollow float structure itself has another line of defense. It is difficult for aquatic organisms to continue to penetrate and tear into the wall surface of the hollow float structure through the perforation on the outer shell 11. Therefore, the service life of the float under the double line of defense can also be extended. In addition, the main body 12 of the float can also be designed with one part of the structure being a filled float structure made of lightweight plastic and the other part being a hollow float structure made of lightweight plastic. For example, the middle part of the main body 12 of the float is a hollow float structure and its outer part is a filled float structure.

[0065] It should also be noted that lightweight plastics that can be used as floating structures include, but are not limited to, polyethylene (PE), polypropylene (PP) and its foam (PPF), and polystyrene (PS). Polyethylene (PE) is a lightweight, flexible plastic with good toughness and impact resistance. Floats made from this material are lightweight, easy to install and transport, and highly corrosion-resistant. Polypropylene (PP) and its foam (PPF) are lightweight, strong plastics, with polypropylene foam having even lower density and good thermal stability. Polypropylene foam also has good sound and heat insulation properties. Floats made from polypropylene are also lightweight and corrosion-resistant, making them suitable for various aquatic applications. Polystyrene (PS) is a lightweight, strong plastic commonly used in the manufacture of foam plastics. Floats made from polystyrene also have high buoyancy and are lightweight, but may not be as corrosion-resistant as polyethylene and polypropylene floats. These lightweight plastic floats share the following characteristics: they are lightweight, making them easy to install, handle, and transport, thus reducing costs; they are highly corrosion-resistant, able to withstand the erosion of various chemicals, extending their service life; and they have excellent impact resistance, able to withstand certain external impacts and are not easily damaged.

[0066] In some specific implementation plans, refer to Figures 2-6 As shown, the aforementioned float shell 11 may specifically include a loading box 111 and a sealing plate 112. The top of the loading box 111 has an open opening, and the sealing plate 112 covers the open opening to form a loading cavity 110. In actual production, the manufactured float body 12 can be loaded into the loading box 111, and then the sealing plate 112 can be placed on the open opening at the top of the loading box 111. The top two sides of the loading box 111 may be designed with first box edges 111a1, and the first box edges 111a1 may be designed with corresponding first edge holes 111a2. The corresponding edge position of the sealing plate 112 may be designed with second edge holes 1124. The connection between the sealing plate 112 and the loading box 111 can be achieved by fasteners connecting the first edge holes 111a2 and the second edge holes 1124. It should be noted that the fitting method between the sealing plate 112 and the opening can be, but is not limited to, a sealed fit. For example, a seal can be designed between the edge of the sealing plate 112 and the loading box 111, and then fixed with fasteners. Alternatively, it can be connected directly using other methods, such as waterproof adhesive. Of course, the fitting method between the sealing plate 112 and the opening can also be designed as a non-sealed fit. By designing the loading box 111 and the sealing plate 112 into a separate fitting structure, it is more convenient to install the float body 12 into the float shell 11.

[0067] It is worth mentioning that the design of the floating body shell 11 as a separate assembly of the loading box 111 and the sealing plate 112 is merely an example of an embodiment of this application. In actual applications, the floating body shell 11 can also be designed as a structure with upper and lower shells joined together, or it can be designed as described above. Figure 9 As shown, the float shell 11 is designed as an integral structure of the loading box 111 and the sealing plate 112. At least one end of the loading box 111 is designed with an opening. The float body 12 is loaded through the end opening and then sealed by the end plate. In actual application, the configuration can be selected according to actual needs and ease of processing, and no more specific limitations are made here.

[0068] In a further implementation plan, refer to Figures 2-8 The aforementioned loading box 111 may specifically include a groove-shaped main box 111a and end plates 111b disposed at both ends of the groove-shaped main box 111a. The groove-shaped main box 111a and the end plates 111b may be designed as an integrally formed structure, such as integral injection molding or molding, or they may be designed as a separate fixed connection structure. For example, the end plate 111b may be designed as a box-shaped structure, that is, the edge of the end plate 111b is provided with a second box edge 111b1 extending towards or away from the groove-shaped main box 111a. This second box edge 111b1 overlaps and fits with the end side edge of the loading box 111, and the second box edge 111b1 is provided with a third edge hole 111b2, through which the end plate 111b is fixed to the end side of the groove-shaped main box 111a by fasteners. Of course, the end plate 111b can also be fixed to the end of the slotted main box 111a in other ways, such as by waterproof adhesive. In actual application, the arrangement can be selected according to actual needs, and no more specific restrictions are made here.

[0069] It should be noted that at least one of the loading box 111 and the sealing plate 112 can be optionally designed as a corrosion-resistant plastic component. That is, only the loading box 111 can be designed as a corrosion-resistant plastic component, while the sealing plate 112 can be designed as a corrosion-resistant component of another material; or only the sealing plate 112 can be designed as a corrosion-resistant plastic component, while the loading box 111 can be designed as a corrosion-resistant component of another material; or both the loading box 111 and the sealing plate 112 can be designed as corrosion-resistant plastic components. Specifically, the corrosion-resistant plastic component can be, but is not limited to, plastics made of materials such as polyethylene (PE), polypropylene (PP) and its foam (PPF), or polystyrene (PS). By designing it in the above manner, the weight of the float shell 11 can be reduced as much as possible.

[0070] It is understandable that at least one of the aforementioned loading box 111 and sealing plate 112 can be designed as a corrosion-resistant metal component. Compared with corrosion-resistant plastic components, corrosion-resistant metal components are more stable and reliable in structure and less prone to deformation. For example, designing the sealing plate 112 as a corrosion-resistant metal component makes the sealing plate 112 more resistant to deformation and better meets the requirements of the sealing plate 112 as a maintenance walkway.

[0071] In a further implementation plan, refer to Figure 2 In conjunction with point 6, the aforementioned sealing plate 112 may specifically include a sealing plate body 1121 and transverse reinforcing ribs 1122 disposed on the top surface of the sealing plate body 1121. The number of transverse reinforcing ribs 1122 is multiple, and they are arranged at intervals on the top surface of the sealing plate body 1121, specifically arranged sequentially at intervals along the longitudinal direction. The transverse reinforcing ribs 1122 may be reinforcing ribs extending in the transverse direction, or they may be reinforcing ribs extending in a direction with a certain angle (an acute angle) to the transverse direction. Furthermore, the transverse reinforcing ribs 1122 may be integrally formed with the sealing plate 112, or they may be separately fixedly connected; no further specific limitations are made here. By designing the transverse reinforcing ribs 1122, not only can the transverse tensile and bending strength of the sealing plate 112 be enhanced, but the upper surface of the sealing plate 112 can also have a certain anti-slip effect, making it more suitable as a maintenance walkway.

[0072] In some other specific implementation schemes, refer to Figure 2 As shown, the sealing plate body 1121 may also be provided with longitudinal reinforcing ribs 1123. There are multiple longitudinal reinforcing ribs 1123, which are arranged at intervals along the transverse direction on the top surface of the sealing plate body 1121. By designing the longitudinal reinforcing ribs 1123, the longitudinal tensile and bending strength of the sealing plate 112 can be enhanced.

[0073] In a further implementation plan, refer to Figure 1 , Figure 2 and Figure 7 As shown, the aforementioned longitudinal reinforcing rib 1123 can be designed as a metal part, and the longitudinal reinforcing rib 1123 is provided with a first mounting structure 1123a and a second mounting structure 1123b. The first mounting structure 1123a is used for fixed connection with the sealing plate body 1121, and the first mounting structure 1123a can specifically include, but is not limited to, a fixing hole. The second mounting structure 1123b is used for connection with the photovoltaic bracket 2, and the second mounting structure 1123b can specifically include, but is not limited to, an embedding groove, into which the photovoltaic bracket 2 of the photovoltaic module 3 can be embedded. By designing this structural form, the installation of the photovoltaic bracket 2 becomes more convenient.

[0074] In some more specific embodiments, the outer wall of the aforementioned float hull 11 can also be provided with an antifouling coating, specifically a coating structure with anti-corrosion and microbial repellent functions. By designing this antifouling coating, the risk of corrosion and aquatic organism attack on the float hull 11 can be better reduced. The antifouling coating can specifically be a biofouling coating, an electrolytic antifouling coating, a silicate antifouling coating, a novel composite antifouling coating, or other antifouling coatings. Specifically, biofouling coatings: The development of biofouling coatings is based on the natural anti-attachment properties of marine organisms. Marine organisms such as dolphins, crabs, and sponges can secrete special chemical substances that repel or inhibit attaching organisms, or prevent other marine organisms from attaching to their bodies through their special surface morphology. Based on these mechanisms, biofouling coatings have been developed. Biological agents generally have good environmental acceptability, most can decompose naturally, do not produce permanent bioaccumulation, and are widely available. Electrolytic antifouling coatings: These coatings use a weak current to electrolyze seawater to produce substances with antifouling effects, such as hypochlorous acid ions. Silicate antifouling coatings, primarily composed of soluble silicates, form a long-term, stable, highly alkaline coating on the surface of floating bodies, making it difficult for marine organisms to survive. A novel composite antifouling coating, synthesized using sol-gel technology and combining amphiphilic telomeres, zirconium oxide sol, and other materials, exhibits superior mechanical properties and significant antibacterial efficacy. Its self-cleaning and antifouling capabilities are particularly outstanding, and its high transparency makes it a promising candidate for applications in marine facilities and other fields. Other antifouling coatings include nano-sized cuprous oxide antifouling coatings: cuprous oxide is made into nano-sized particles and combined with effective biocides and algaecides to create the antifouling coating. The nano-sized particles are encapsulated within the antifouling coating's base material, preventing leakage but allowing for the slow release of ions, thus providing long-lasting antifouling protection. Another example is microencapsulation technology antifouling coatings: microencapsulation treatment improves the exudation performance of biocides, extends the antifouling period, and increases formulation flexibility. The coating method involves depositing polymer materials onto a central core or active substance. By changing the type of polymer material and the thickness of the deposit, the actual release rate of the biocide can be adjusted. Another example is flocked non-toxic antifouling materials: fibrous, fluffy materials are applied to the surface of a float. Because the fibers move continuously under the impact of seawater, marine organisms find it difficult to attach to this unstable material, thus achieving an antifouling effect. Yet another example is antifouling self-cleaning coatings: such as ZS-533 marine antifouling self-cleaning coating, which uses specific resins and grafting technology to form a thin, dissolving layer several micrometers thick on the coating surface, which can repel and dissolve marine organisms and plants for a long time. This coating has good anti-corrosion properties, is resistant to acid and alkali corrosion, and does not contain heavy metals or toxic materials, making it safe and environmentally friendly. Therefore, for the need to prevent corrosion from seawater microbial secretions and repel microorganisms, there are various coating technologies and materials available. In practical applications, selection and optimization should be based on the specific usage environment and requirements.

[0075] In some specific implementations, the loading cavity 110 can be designed to have multiple loading areas, with multiple float bodies 12 corresponding to and adapted to each loading area. By designing this structure, the processing difficulty of the float bodies 12 can be reduced, and handling and assembly can be made more convenient.

[0076] Another embodiment of this application provides a floating photovoltaic platform, including a float 1. The floats 1 are connected by connecting components to form a floating platform. Photovoltaic modules 3 are installed on the floating platform via photovoltaic brackets 2. At least a portion of the float 1 is the float 1 for waterborne photovoltaics described in any of the above embodiments. Since the aforementioned float 1 has the aforementioned technical effects, the floating photovoltaic platform having the aforementioned float 1 should also have corresponding technical effects, which will not be elaborated further here.

[0077] Furthermore, another embodiment of this application provides a photovoltaic power station, including a floating photovoltaic platform, wherein the floating photovoltaic platform is the floating photovoltaic platform described in the above-described scheme. Since the floating photovoltaic platform has the aforementioned technical effects, the photovoltaic power station with the floating photovoltaic platform should also have corresponding technical effects, which will not be elaborated further here.
