Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic power generation, and in particular relates to a floating photovoltaic platform for photovoltaic panel power generation and a photovoltaic power generation system. Background Art

[0002] As the global demand for renewable energy continues to increase, photovoltaic power generation, as a clean and renewable energy form, has received widespread attention and application. However, traditional ground photovoltaic power stations and rooftop photovoltaic power stations require a large amount of land resources, which is particularly prominent in areas with tight land resources. Therefore, floating photovoltaic platforms came into being. Floating photovoltaic platforms are an innovative photovoltaic power generation technology that uses floating bodies or platforms on the water to float photovoltaic modules, inverters and other power generation equipment on the water surface for power generation. It not only solves the problem of tight land resources, but also makes full use of the vast water space and realizes the diversified application of photovoltaic power generation.

[0003] However, the existing floating photovoltaic platforms are difficult to produce and install due to their complex structures, resulting in a long processing cycle and timeliness that cannot meet the requirements of photovoltaic power generation projects. Secondly, in terms of material costs, the material costs used in existing floating production platforms are relatively high. Due to the large number of photovoltaic modules installed on a single platform, the volume of a single platform is large, which increases production costs. Summary of the invention

[0004] The purpose of the present invention is to provide a floating photovoltaic platform and a photovoltaic power generation system for photovoltaic panel power generation, so as to solve the technical defects in the prior art that the existing floating photovoltaic platforms are complex in structure, difficult to produce and install, resulting in a long processing cycle and timeliness that cannot meet the requirements of photovoltaic power generation projects; secondly, in terms of material cost, the material cost used in the existing floating production platforms is relatively high. Since a large number of photovoltaic modules are installed on a single platform, the volume of a single platform is large, which leads to increased production costs.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, a floating photovoltaic platform for photovoltaic panel power generation is provided, comprising: A plurality of carrying devices are connected to each other through a cutting assembly, and a power generation assembly is provided in each carrying device; A limiting device is arranged around the carrying device, and its end extends to the seabed; Wherein, the bearing device comprises a bearing block, the bearing block is made of concrete, and a cavity is formed on the bearing block; A polymer pipe is arranged in the cavity, and the polymer pipe is filled with foaming material.

[0006] Furthermore, the top of the bearing block has an opening, the power generation component is arranged in the opening, and two adjacent bearing blocks are connected through the reduction component.

[0007] Furthermore, the cutting assembly includes a first cutting unit and a second cutting unit, the first cutting unit is arranged between two adjacent bearing blocks, and the second cutting unit is arranged on two opposite sides of the first cutting unit.

[0008] Further, the first abatement unit and the second abatement unit overlap axially; Wherein, the first reduction unit is used to reduce the tension between two adjacent bearing blocks; The second reduction unit is used to reduce the load between two adjacent bearing blocks.

[0009] Furthermore, the first reduction unit and the bearing block are riveted together.

[0010] Furthermore, the first abatement unit comprises a abatement plate, the abatement plate is filled with rubber material, and an inner hoop is arranged on the abatement plate.

[0011] Furthermore, the abatement plate is an annular structure, and the inner hoop is arranged at the center of the abatement plate.

[0012] Furthermore, the second reduction unit is a flexible limiter.

[0013] Furthermore, the power generation component is a photovoltaic component.

[0014] In a second aspect, a photovoltaic panel power generation system is provided, comprising a photovoltaic panel power generation system body, wherein the photovoltaic panel power generation system body is installed on the floating photovoltaic platform for photovoltaic panel power generation as described above.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The bearing device adopts a bearing block made of concrete, which has high strength and durability, and can resist external forces such as buoyancy in water, wind and waves, to ensure the stable floating of the power generation components on the water surface. At the same time, the cost of concrete materials is relatively low, which is conducive to reducing the overall construction cost. Secondly, a polymer pipe is provided in the cavity of the bearing block, and the polymer pipe is filled with foaming material, which not only increases the buoyancy of the bearing block, but also improves its impact resistance. The foaming material has good buffering properties, which can effectively absorb and disperse external force impacts and protect the internal power generation components from damage.

[0016] 2. The design of the opening on the top of the bearing block allows the power generation components to be easily installed and disassembled, which greatly simplifies the assembly process of the photovoltaic platform. At the same time, the connection between the bearing block and the power generation component has become more flexible and convenient, which is conducive to the rapid deployment and expansion of the photovoltaic platform. Secondly, the adjacent bearing blocks are connected by eliminating components. This connection method not only enhances the overall stability of the photovoltaic platform, but also reduces mutual collision and friction caused by factors such as wind and waves.

[0017] 3. The first reduction unit is directly connected to the adjacent bearing blocks, which can effectively absorb and disperse the horizontal impact and vibration caused by external forces such as wind, waves, and water flow. The setting of the second reduction unit further enhances the buffering capacity in the vertical direction, forming a three-dimensional shock absorption system, so that the photovoltaic platform can maintain higher stability and durability when facing complex and changeable water environments.

[0018] 4. Since the first reduction unit and the second reduction unit overlap axially, they can share the same spatial position, thereby significantly improving the space utilization of the photovoltaic platform. This compact design helps to reduce the use of materials, reduce costs, and increase the overall aesthetics of the photovoltaic platform. Secondly, the axial overlap design reduces the connection points between the reduction components and simplifies the overall structure of the photovoltaic platform, which not only improves the stability of the structure, but also reduces the potential risks caused by failure of the connector.

[0019] 5. Riveting, as a mechanical connection method, can provide reliable connection strength. Riveting between the first reduction unit and the bearing block can ensure a firm connection between the two, which is not easy to loosen or fall off, forming a whole, thereby improving the overall structural stability of the photovoltaic platform; at the same time, the riveted connection is relatively simple and easy to operate. During the installation of the photovoltaic platform, the use of riveting can greatly simplify the installation steps and improve the installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0025] In the description of the embodiments of the present invention, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use, it is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0026] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0027] As the global demand for renewable energy continues to increase, photovoltaic power generation, as a clean and renewable energy form, has received widespread attention and application. However, traditional ground photovoltaic power stations and rooftop photovoltaic power stations require a large amount of land resources, which is particularly prominent in areas with tight land resources. Therefore, floating photovoltaic platforms came into being. Floating photovoltaic platforms are an innovative photovoltaic power generation technology that uses floating bodies or platforms on the water to float photovoltaic modules, inverters and other power generation equipment on the water surface for power generation. It not only solves the problem of tight land resources, but also makes full use of the vast water space and realizes the diversified application of photovoltaic power generation.

[0028] However, the existing floating photovoltaic platforms are difficult to produce and install due to their complex structures, resulting in a long processing cycle and timeliness that cannot meet the requirements of photovoltaic power generation projects. Secondly, in terms of material costs, the material costs used in existing floating production platforms are relatively high. Due to the large number of photovoltaic modules installed on a single platform, the volume of a single platform is large, which increases production costs.

[0029] In order to solve the above technical defects, the inventor provides a floating photovoltaic platform and a photovoltaic power generation system for photovoltaic panel power generation.

[0030] The present invention is further described in detail below in conjunction with the accompanying drawings: like Figure 1-5As shown, in a first aspect of an embodiment of the present invention, a floating photovoltaic platform for photovoltaic panel power generation is provided, comprising a plurality of supporting devices 1, wherein the plurality of supporting devices 1 are connected to each other via a reduction assembly 3 to form a floating photovoltaic platform, wherein a power generation assembly 2 is arranged in the supporting device 1, and the power generation assembly 2 is a photovoltaic assembly; the plurality of supporting devices 1 are connected via the reduction assembly 3, and this connection method can reduce mutual collision and friction caused by factors such as wind and waves, reduce energy loss, and thus improve the power generation efficiency of the entire photovoltaic platform; at the same time, since the photovoltaic platform adopts a modular design, the supporting device 1 and the power generation assembly 2 therein can be flexibly combined and expanded, so that the photovoltaic platform can be scaled according to actual needs to meet the needs of different waters and power generation. The limiting device is arranged around the bearing device 1, and its end extends to the seabed, and is used to fix the bearing device 1. The limiting device specifically includes a mooring rope 6 installed around the bearing device 1, and a gravity anchor 7 is installed at its end; wherein the bearing device 1 includes a bearing block 101, and the bearing block 101 is made of concrete, and a cavity is opened on the bearing block 101; a polymer pipe 102 is arranged in the cavity, and the polymer pipe 102 is filled with a foaming material 103, and the foaming material 103 is a low-density foaming material. The bearing block 101 made of concrete in the bearing device 1 has high strength and durability, and can resist external forces such as buoyancy, wind and waves in the water, and ensure the stable floating of the power generation component 2 on the water surface. At the same time, the cost of concrete materials is relatively low, which is conducive to reducing the overall construction cost. Secondly, a polymer pipe 102 is provided in the cavity of the bearing block 101, and the polymer pipe 102 is filled with a foam material 103, which not only increases the buoyancy of the bearing block 101, but also improves its impact resistance. The foam material 103 has good buffering performance, can effectively absorb and disperse external force impact, and protect the internal power generation component 2 from damage. Figure 1 and Figure 2 As shown, the top of the carrier block 101 has an opening 5, the power generation component 2 is arranged in the opening 5, and two adjacent carrier blocks 101 are connected by the reduction component 3; the design of the opening 5 on the top of the carrier block 101 allows the power generation component 2 to be easily installed and disassembled, which greatly simplifies the assembly process of the photovoltaic platform. At the same time, the connection between the carrier block 101 and the power generation component 2 also becomes more flexible and convenient, which is conducive to the rapid deployment and expansion of the photovoltaic platform. The adjacent carrier blocks 101 are connected by the reduction component 3, which not only enhances the overall stability of the photovoltaic platform, but also reduces the mutual collision and friction caused by factors such as wind and waves. The design of the reduction component 3 takes into account the fluctuation of the water surface and the influence of wind, and can effectively absorb and disperse these external forces to protect the photovoltaic platform from damage. Figure 1-Figure 3As shown, the reduction component 3 includes a first reduction unit 301 and a second reduction unit 302. The first reduction unit 301 is arranged between two adjacent bearing blocks 101, and the second reduction unit 302 is arranged on the opposite sides of the first reduction unit 301. The second reduction unit 302 is preferably a flexible stopper. The first reduction unit 301 is directly connected to the adjacent bearing blocks 101, and can effectively absorb and disperse the impact and vibration in the horizontal direction caused by external forces such as wind, waves, and water flow. The setting of the second reduction unit 302 further enhances the buffering capacity in the vertical direction, forming a three-dimensional shock absorption system, so that the photovoltaic platform can maintain higher stability and durability when facing complex and changeable water environments. Secondly, since the reduction component 3 adopts a sub-unit design, each unit can be independently adjusted and optimized according to actual needs to adapt to the wave characteristics, water flow speed, and relative displacement between the bearing blocks 101 in different waters. This flexibility enables the photovoltaic platform to be more widely used in various water environments, improving its adaptability and application range. In addition, overall, the reduction component 3 as a whole can play an effective buffering and shock absorbing role, reducing the relative movement between the bearing block 101 and the power generation component 2 caused by external force impact, thereby reducing energy loss, helping to improve the overall power generation efficiency of the photovoltaic platform, and ensuring the stability and reliability of power output; and by reducing the impact and vibration of external forces on the bearing block 101 and the power generation component 2, the reduction component 3 also helps to extend the service life of these components, not only reducing maintenance costs, but also improving the long-term economic benefits of the photovoltaic platform. Finally, the modular design of the reduction component 3 makes its replacement and maintenance more convenient. When a unit fails or is damaged, it can be replaced separately without affecting the operation of the entire photovoltaic platform, improving maintenance efficiency and reducing downtime.

[0031] Furthermore, the first reduction unit 301 and the second reduction unit 302 overlap axially and can share the same spatial position, thereby significantly improving the space utilization of the photovoltaic platform, reducing the use of materials, reducing costs, and increasing the overall aesthetics of the photovoltaic platform. The first reduction unit 301 is riveted 4 to the bearing block 101. The first reduction unit 301 is used to reduce the tension between two adjacent bearing blocks 101. When two adjacent bearing devices 1 are relatively far apart, the first reduction unit 301 can reduce the tension to avoid damage to the bearing device 1 and the power generation component 2; the second reduction unit 302 is used to reduce the load between two adjacent bearing blocks 101 to prevent the two adjacent bearing devices 1 from colliding when they are close to each other.

[0032] like Figure 4As shown, the first reduction unit 301 includes a reduction plate 3011, and the reduction plate 3011 is filled with a rubber material 3012. The rubber material 3012 is preferably a high-strength, polymer material. As a high-strength, polymer material, the rubber material 3012 has excellent elasticity and shock-absorbing properties. When the photovoltaic platform is subjected to external forces such as wind, waves, and water flow, the rubber material 3012 can absorb and disperse these energies, reduce the impact and vibration on the bearing block 101, improve the overall structural strength of the photovoltaic platform, and extend its service life. An inner hoop 3013 is provided on the reduction plate 3011. Specifically, the reduction plate 3011 is an annular structure, and the inner hoop 3013 is arranged at the center of the reduction plate 3011; the reduction plate 3011 adopts an annular structure, which not only increases its structural strength, but also enables the rubber material 3012 to be more evenly distributed in the plate, thereby improving the shock absorption effect. The annular structure can also better adapt to the relative displacement between the bearing blocks 101 and maintain the stability of the structure; the inner hoop 3013 is arranged at the center of the reduction plate 3011, which plays a reinforcing role. It can effectively prevent the rubber material 3012 from deformation or rupture after being subjected to stress for a long time, and further improve the structural stability and durability of the first reduction unit 301.

[0033] In the second aspect, this embodiment provides a photovoltaic panel power generation system, including a photovoltaic panel power generation system body, and the photovoltaic panel power generation system body is installed on the floating photovoltaic platform for photovoltaic panel power generation as described above. By installing the photovoltaic panel power generation system on the floating photovoltaic platform described above, the photovoltaic panel can receive more uniform and sufficient light, which helps to improve the power generation efficiency of the photovoltaic panel and ensure the stability of power output. Secondly, the environment on the sea or water surface is relatively cool, which helps to reduce the temperature of the photovoltaic panel, thereby reducing the heat loss caused by high temperature, further improving the power generation efficiency of the photovoltaic panel, so that the entire photovoltaic panel power generation system can generate more electricity, and does not need to occupy a large amount of land resources. For areas with tight land resources, it is a very effective way of energy utilization. In terms of installation, the installation and operation and maintenance costs of the floating photovoltaic platform are relatively low, and it is easy to maintain, which can reduce the operation and maintenance costs, improve the overall economic benefits, and can also play a certain role in ecological protection; for example, the photovoltaic panel can block sunlight, reduce the growth of algae on the water surface, and prevent problems such as eutrophication of water bodies. Finally, since the structure of the floating photovoltaic platform is relatively simple and easy to adjust, it can be expanded or reduced according to actual needs, which helps to improve the flexibility and adaptability of the photovoltaic panel power generation system and meet different energy needs. In summary, the use of floating photovoltaic platforms to generate electricity using clean energy reduces dependence on fossil energy, thereby reducing greenhouse gas emissions and environmental pollution, and helps promote sustainable development and achieve green energy transformation.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit its protection scope. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the field should understand that after reading the present invention, those skilled in the art can still make various changes, modifications or equivalent substitutions to the specific implementation methods of the invention, but these changes, modifications or equivalent substitutions are all within the protection scope of the pending claims of the invention.
