[0002] At present, floating photovoltaic platforms are indispensable structures for building water-based photovoltaic power stations. In order to improve the wind and wave resistance of floating photovoltaic platforms under harsh working conditions, more and more floating photovoltaic platforms are adopting floating structures. The floating structures in the existing technology are required to ensure a certain structural strength because they have to cope with the harsh marine environment. Usually, the overall structural material of the floating photovoltaic platform is the same as the material of the outermost layer of the floating photovoltaic platform. Generally, a floating body made of high-performance concrete is used to ensure the overall stability and reliability of the floating photovoltaic platform. However, this also leads to an increase in production costs. Therefore, it is urgent to design a floating photovoltaic platform that can significantly reduce production costs while ensuring overall stability. Utility Model Content

[0011] The present invention provides a floating photovoltaic platform, comprising a first floating platform structure, a second floating platform structure, and a third floating platform structure. The first floating platform structure has a lower structural strength than the second floating platform structure, which is lower than the third floating platform structure.

[0023] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.
[0024] like Figures 1 to 4 As shown, this embodiment provides a floating photovoltaic platform, which includes a first floating platform structure 1, a second floating platform structure 2, and a third floating platform structure 3. The second floating platform structure 2 is disposed around the periphery of the first floating platform structure 1; the third floating platform structure 3 is disposed around the periphery of the second floating platform structure 2 and connected to the second floating platform structure 2; the top surfaces of the first floating platform structure 1, the second floating platform structure 2, and the third floating platform structure 3 are all capable of mounting photovoltaic panels, and the structural strength of the first floating platform structure 1 is less than that of the second floating platform structure 2, which is less than that of the third floating platform structure 3.
[0025] With the floating photovoltaic platform of the present invention, since the third floating platform structure 3 is in the outermost layer, such a configuration can ensure that the structural strength of the third floating platform structure 3 is high, thereby being able to resist the impact of larger waves. Subsequently, the structural strength of the second floating platform structure 2 can be made smaller than that of the third floating platform structure 3, thereby ensuring the overall structural strength of the second floating platform structure 2 while also being able to resist smaller waves. Similarly, the structural strength of the first floating platform structure 1 can be made smaller than that of the second floating platform structure 2, thereby also being able to ensure the overall structural strength of the first floating platform structure 1 while also being able to resist smaller waves, thereby ensuring the overall reliability and stability of the floating photovoltaic platform, thereby ensuring the stable operation of the photovoltaic panels. Since the higher the structural strength, the higher the cost, compared to the prior art, the present invention can gradually reduce the structural strength of the floating platform structure, thereby effectively reducing the production cost and effectively solving the problem of high production cost of floating photovoltaic platforms in the prior art.
[0026] In some embodiments, the wave-resistant height of the first floating platform structure 1 is H1, H1≤1m; the wave-resistant height of the second floating platform structure 2 is H2, 1m<H2≤2m; and the wave-resistant height of the third floating platform structure 3 is H3, 3m≤H3≤5m. The wave-resistant height H3 of the third floating platform structure 3 can be limited within the aforementioned numerical range, thereby ensuring that the third floating platform structure 3 can withstand greater wave impact forces. At the same time, limiting the wave-resistant height H2 of the second floating platform structure 2 within the aforementioned numerical range can reduce the production cost of the second floating platform structure 2 while ensuring the structural strength of the second floating platform structure 2. Similarly, since the first floating platform structure 1 is located in the innermost layer and its wave impact force is relatively small, limiting the wave-resistant height H1 of the first floating platform structure 1 within the aforementioned numerical range can reduce the production cost of the first floating structure 1 while ensuring the structural strength of the first floating platform structure 1.
[0027] It should be noted that wave resistance refers to the maximum wave height that a ship, pontoon, offshore platform or other water-based structure can withstand while maintaining stability. It is one of the indicators that measure the ability of water-based structures to resist wave attacks.
[0028] In this embodiment, if Figure 1 and Figure 4 As shown, the first floating platform structure 1 includes a plurality of first floating platform units 11 arranged side by side along a first direction. Each first floating platform unit 11 includes a plurality of first floating bodies 111 and a plurality of connectors 112. Two adjacent first floating bodies 111 are connected by a connector 112. Simultaneously, the plurality of connectors 112 are sequentially connected along a second direction to connect the plurality of first floating bodies 111. The first direction and the second direction are perpendicular. This arrangement forms a generally rectangular shape formed by the plurality of first floating platform units 11 arranged side by side along the first direction.
[0029] Optionally, the connecting member 112 includes a first connecting block, a second connecting block, a first connecting rod, a second connecting rod and a third connecting rod, one end of the first connecting block is connected to one end of the second connecting block through the first connecting rod, the second connecting rod is connected to the other end of the first connecting block, the second connecting rod passes through a first floating body 111 to connect a first floating body 111 to the first connecting block, the third connecting rod is connected to the other end of the second connecting block, and the third connecting rod passes through an adjacent first floating body 111 to connect an adjacent first floating body 111 to the second connecting block.
[0030] Specifically, the first float 111 is a roto-molded float made of linear polyethylene resin. Thus, the first float 111 is configured as a roto-molded float, which can significantly reduce the production cost of the first float 111 while ensuring structural strength.
[0031] Roto-molded floats are manufactured using a rotational molding process and are primarily used for various water operations and buoyancy support. They are typically roto-molded from linear polyethylene resin and then treated with polyurethane foam. They offer lightweight, high buoyancy, and resistance to impact, acid, and alkali.
[0032] In some embodiments, the second floating platform structure 2 includes multiple second floating platform units 21. Each second floating platform unit 21 defines a first protection zone 22. The multiple second floating platform units 21 are sequentially arranged along the periphery of the first protection zone 22, with the first floating platform unit 11 located within the first protection zone 22. This arrangement ensures that the first floating platform unit 11 is protected from all four directions, and an appropriate number of second floating platform units 21 can be selected based on actual site needs.
[0033] Specifically, the second floating platform unit 21 includes a second floating body 211, a third floating body 212, a fourth floating body 213, and a fifth floating body 214, connected end to end. The second floating body 211 and the fourth floating body 213 are parallel, while the third floating body 212 and the fifth floating body 214 are parallel. The second floating body 211, the third floating body 212, the fourth floating body 213, and the fifth floating body 214 enclose the first protection area 22. In the present invention, the second floating platform unit 21 is rectangular in shape.
[0034] In the present invention, the second floating platform unit 21 is made of fiber polymer. This configuration can reduce the production cost of the second floating platform unit 21 while ensuring the structural strength of the second floating platform unit 21. Fiber polymer is an advanced composite material with high strength and low density.
[0035] In this embodiment, the third floating platform structure 3 includes a plurality of third floating platform units 31. Each of the third floating platform units 31 has a second protection area 32. The plurality of third floating platform units 31 are sequentially arranged along the periphery of the second protection area 32. The first floating platform unit 11 and the second floating platform unit 21 are both located within the second protection area 32. This arrangement provides comprehensive protection for the first floating platform unit 11 and the second floating platform unit 21.
[0036] Specifically, the third floating platform unit 31 is made of UHPC. This ensures the structural strength of the third floating platform unit 31 while reducing its production costs. UHPC stands for Ultra High Performance Concrete, a special type of concrete with exceptional strength, durability, low porosity, and strong corrosion resistance.
[0037] This embodiment also provides a photovoltaic system, including the floating photovoltaic platform in the above-mentioned scheme. With the photovoltaic system of the present invention, since the third floating platform structure 3 is at the outermost layer, such a configuration can ensure that the structural strength of the third floating platform structure 3 is high, thereby being able to resist the impact of larger waves. Subsequently, the structural strength of the second floating platform structure 2 can be made smaller than that of the third floating platform structure 3. While ensuring the overall structural strength of the second floating platform structure 2, it can also resist smaller wave impacts. Similarly, the structural strength of the first floating platform structure 1 can be made smaller than that of the second floating platform structure 2. In this way, while ensuring the overall structural strength of the first floating platform structure 1, it can also resist smaller wave impacts, thereby ensuring the overall reliability and stability of the floating photovoltaic platform, thereby ensuring the stable operation of the photovoltaic panels. Since the higher the structural strength, the higher the cost, compared with the prior art, the present invention can gradually reduce the structural strength of the floating platform structure, thereby effectively reducing the production cost and effectively solving the problem of high production cost of floating photovoltaic platforms in the prior art.

Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
