DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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. 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.

[0032] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment.

[0033] like Figures 1 to 8As shown, the floating platform 100 includes a base 10, a plurality of upper covers 20 and a plurality of floats 30. The base 10 has a first surface 11 and a second surface 12 opposite to each other. A plurality of mounting holes 13 are arranged on the base 10. The mounting holes 13 penetrate the base 10 from the first surface 11 to the second surface 12. The plurality of upper covers 20 are arranged on the first surface 11. The upper covers 20 are opposite to the mounting holes 13. The upper covers 20 cover the mounting holes 13. The plurality of floats 30 are connected to the second surface 12. The floats 30 are opposite to the mounting holes 13. The floats 30 cover the mounting holes 13. The floats 30 are used to contact with the fluid, and the upper covers 20 are used to install photovoltaic modules.

[0034] In the embodiment of the present invention, the floating platform 100 includes a base 10, a plurality of upper covers 20 and a plurality of floats 30. The base 10 has a first surface 11 and a second surface 12 opposite to each other. The base 10 is provided with a plurality of mounting holes 13 extending from the first surface 11 to the second surface 12, and the mounting holes 13 penetrate the base 10. The arrangement of the mounting holes 13 makes the base 10 partially hollow inside, which can reduce the mass of the base 10 and enable the base 10 to float on the fluid. The upper cover 20 is arranged on the first surface 11, and the upper cover 20 is opposite to the mounting hole 13 and covers the mounting hole 13, that is, the upper cover 20 can cover the mounting hole 13, providing an installation position for the photovoltaic module, so that the photovoltaic module can be installed on the floating platform 100 through the upper cover 20. Multiple buoys 30 are connected to the second surface 12, opposite to the mounting hole 13, that is, the upper cover 20 and the buoys 30 are respectively connected to the opposite sides of the base 10, so that when the floating platform 100 is placed in the fluid, the multiple buoys 30 can be located in the fluid and provide buoyancy for the upper base 10, the upper cover 20 and the photovoltaic module. In the present application, the floating platform 100 includes a base 10, multiple upper covers 20 and multiple buoys 30, wherein the buoys 30 are located in the fluid to provide buoyancy, and mainly withstand seawater immersion corrosion; the upper cover 20 and the base 10 carry the photovoltaic module, and withstand the impact of waves, mutual collisions between the floating platforms 100, ultraviolet radiation, etc. These parts can be designed according to their different forces, and the functions of providing buoyancy and anti-collision are decomposed into different components, avoiding the problem of overall consideration of the wind resistance and buoyancy of the floating platform 100 for design, which can simplify the design and structure of the floating platform 100, reduce the difficulty of production and transportation, and the production cost of the floating platform 100.

[0035] It should be noted that the upper cover 20 covers the mounting hole 13, so that when installing the photovoltaic module, the photovoltaic module can be installed on the upper cover 20. In addition, the upper cover 20 can also provide a stepping position for the staff as an operation and maintenance channel, so that the staff can maintain and inspect the floating platform 100 or the photovoltaic module.

[0036] In addition, in the embodiment of the present invention, since there are multiple floats 30, the buoyancy is decomposed and provided by multiple floats 30, which can also avoid the problem of overall failure of the floating platform 100 caused by rupture at a certain position of the float 30. Even if one of the floats 30 is broken when subjected to external force, the fluid will enter the broken float 30, and the other floats 30 can still work normally, reducing the amount of fluid entering the floating platform 100, so that the floating platform 100 has a better bearing capacity for photovoltaic modules.

[0037] In addition, in some embodiments, Figure 7 As shown, the multiple floats 30 may include multiple groups of float members 31, and the multiple groups of float members 31 are all connected to the second surface 12. Each group of float members 31 is arranged around the center line of the base 10, and the multiple groups of float members 31 are distributed in sequence along the direction from the center to the edge of the base 10. In two adjacent groups of float members 31, the length of each float member 31 in a group of float members 31 close to the middle of the base 10 is greater than the length of each float member 31 in a group of float members 31 away from the middle of the base 10; the length of the float member 31 is: the distance between the end of the float member 31 away from the second surface 12 and the second surface 12.

[0038] The plurality of buoys 30 include a plurality of groups of buoy components 31, which are all connected to the second surface 12 and can provide buoyancy for the base 10, the upper cover 20, etc. Each group of buoy components 31 is arranged around the center line of the base 10, and the plurality of groups of buoy components 31 are sequentially distributed along the direction from the center to the edge of the base 10, that is, in the direction from the center to the edge of the base 10, a plurality of groups of buoy components 31 are arranged around the center thereof. In two adjacent groups of float members 31, each float member 31 in the group of float members 31 close to the middle of the base 10 is longer than each float member 31 in the group of float members 31 far from the middle of the base 10, so that the length of the float member 31 gradually decreases in the direction from the center to the edge of the base 10. Since the multiple groups of float members 31 are connected to the second surface 12, and the length of the float member 31 is: the distance between the end of the float member 31 facing away from the second surface 12 and the second surface 12, therefore, the ends of the multiple groups of float members 31 facing away from the second surface 12 are not flush, and the distance between the end of the float member 31 facing away from the second surface 12 and the second surface 12 gradually decreases in the direction from the center to the edge of the base 10, from The side of the floating platform 100 where the buoy 30 is arranged presents a streamlined structural layout with a high middle part and a low edge. When the floating platform 100 is placed in a fluid, the draft of the floating platform 100 gradually deepens from the edge to the center, and some of the buoy components 31 on the outer side can bear part of the force first. When the force is transmitted to the buoy component 31 in the middle, the buoy component 31 in the middle can bear less force, so that the multiple buoy components 31 at the bottom of the floating platform 100 can share the thrust applied by the fluid, which is beneficial to improving the hydrodynamic characteristics of the floating platform 100, reducing the hydrodynamic resistance in the horizontal direction, and avoiding the situation where a certain buoy component 31 (for example, the buoy component 31 at the edge) located in the fluid is subjected to a large thrust when wind and waves occur, which easily causes the floating platform 100 to capsize.

[0039] It should be noted that when the floating platform 100 is placed in the fluid, the buoy 30 is located in the fluid, and the upper cover 20 is located above the fluid. The side of the floating platform 100 provided with the buoy 30 can be called the bottom of the buoy 30, and the side of the floating platform 100 provided with the upper cover 20 can be called the top of the buoy 30. The end of the buoy member 31 away from the second surface 12 is the bottom of the buoy member 31. In this embodiment, the distances between the bottoms of multiple groups of buoy members 31 and the second surface 12 are different, so that the bottom of the floating platform 100 presents a streamlined structural layout with a high middle part and a low edge. Among them, high and low are relative to the second surface 12. Specifically, there is a distance between the bottom of the buoy member 31 and the second surface 12. The distance between the bottom of the buoy member 31 in the middle and the second surface 12 is larger. It can be considered that the middle part of the bottom of the floating platform 100 is higher, and the distance between the bottom of the buoy member 31 located at the edge position and the second surface 12 is smaller. It can be considered that the edge part of the bottom of the floating platform 100 is lower.

[0040] It should also be noted that each group of buoy members 31 is arranged around the center line of the base 10, that is, the multiple buoy members 31 in each group of buoy members 31 are arranged in a circle along the circumference of the base 10. In the same group of buoy members 31, the lengths of the buoy members 31 can be consistent. For example, in a certain floating platform 100, five circles of buoy members 31 are arranged at the bottom. The floating platform 100 includes five groups of buoy members 31, and the buoy 30 can include five kinds of buoy members 31 with different lengths. The buoy members 31 with the same length are the same group of buoy members 31. Figure 1 As shown in the figure, a structural diagram of the floating platform 100 is shown. A buoy member 31 is connected to the position opposite to the upper cover 20. The four buoy members 31 located in the middle can all be the buoy members 31 with the longest length, and the 36 buoy members 31 located at the edge can all be the buoy members 31 with the shortest length. The length of each group of buoy members 31 is consistent, and the types of different buoy members 31 required for the floating platform 100 are relatively small, which can facilitate the production of the buoys 30. Of course, in the same group of buoy members 31, the lengths of the buoy members 31 can also be inconsistent, as long as the length of the buoy member 31 closer to the center of each two adjacent buoy members 31 in the direction from the center to the edge of the base 10 is greater than the length of the buoy member 31 closer to the edge.

[0041] Among them, along the direction from the center to the edge of the base 10, in two adjacent float members 31, the length difference of the float members 31 can be about 200 mm, specifically, it can be 200mm, 180mm, 189mm, 198mm, 206mm, 210mm, etc., and this embodiment of the present invention does not make any specific limitation on this.

[0042] In addition, in the embodiment of the present invention, the upper cover 20 can have a variety of structures, and the following two methods are used as examples for explanation:

[0043] Method 1: If Figure 3 As shown, the upper cover 20 includes a cover plate 21 and a connecting member 22 . The cover plate 21 has a mounting surface 23 facing the base 10 . The connecting member 22 is connected to the mounting surface 23 and extends along the circumferential direction of the cover plate 21 . The mounting surface 23 is connected to the first surface 11 , and the connecting member 22 is embedded in the mounting hole 13 .

[0044] The upper cover 20 includes a cover plate 21 and a connecting member 22. The cover plate 21 has a mounting surface 23 facing the base 10, and the connecting member 22 is connected to the mounting surface 23. That is, the mounting surface 23 faces the base 10 and is located at the bottom of the cover plate 21. The connecting member 22 is connected to the bottom of the cover plate 21 and extends along the circumferential direction of the cover plate 21, so that the connecting member 22 can protrude from the mounting surface 23. When the upper cover 20 is connected to the base 10, the mounting surface 23 can be connected to the first surface 11, and the connecting member 22 is embedded in the mounting hole 13.

[0045] In this embodiment, the connecting member 22 is connected to the mounting surface 23 and extends along the circumferential direction of the cover plate 21. The extension form of the connecting member 22 can be various. For example, the connecting member 22 extends 360° along the circumferential direction of the cover plate 21. At this time, the connecting member 22 is arranged in a circle on the mounting surface 23; or, the connecting member 22 extends other angles along the circumferential direction of the cover plate 21, such as 180°, 200°, 300°, etc., or, the connecting member 22 may also include multiple disconnected parts, and the aforementioned multiple parts are distributed along the circumferential direction of the base 10. The specific structural form of the connecting member 22 is not specifically limited in the embodiment of the present invention.

[0046] It should be noted that the cover plate 21 is connected to the first surface 11, and the connector 22 is embedded in the mounting hole 13. It is necessary to satisfy that the size of the connector 22 is smaller than the size of the mounting hole 13, and the size of the cover plate 21 is larger than the size of the mounting hole 13, so as to avoid the problem that the cover plate 21 also passes through the mounting hole 13 and cannot provide an installation position for the photovoltaic module. The connector 22 is embedded in the mounting hole 13. On the one hand, it can provide a pre-positioning effect for the installation of the cover plate 21, which is convenient for finding the setting position of the cover plate 21. On the other hand, the hole wall of the mounting hole 13 can also play a limiting role for the cover plate 21. Even if the connection between the upper cover 20 and the base 10 is disconnected during the use of the floating platform 100, the movement of the connector 22 in the mounting hole 13 is relatively limited, which can avoid the upper cover 20 from moving too much on the base 10, and save time for subsequent maintenance. For the connecting member 22, the surface of the connecting member 22 facing the hole wall of the mounting hole 13 can abut against the hole wall of the mounting hole 13, which has a better limiting effect on the upper cover 20; of course, there can also be a certain gap between the surface of the connecting member 22 facing the hole wall of the mounting hole 13 and the hole wall of the mounting hole 13, which can allow the existence of manufacturing tolerances of the cover body, the connecting member 22, and the mounting hole 13, which is beneficial to manufacturing and installation.

[0047] Method 2: If Figure 3 , Figure 8 As shown, the upper cover 20 includes a cover plate 21 and a connecting member 22. The cover plate 21 has a mounting surface 23 facing the base 10. The connecting member 22 is connected to the mounting surface 23 and extends along the circumferential direction of the cover plate 21. The mounting surface 23 is connected to the first surface 11. The connecting member 22 is passed through the mounting hole 13, and part of the connecting member 22 is passed through the mounting hole 13 and embedded in the float 30.

[0048] The upper cover 20 includes a cover plate 21 and a connecting member 22. The cover plate 21 has a mounting surface 23 facing the base 10, and the connecting member 22 is connected to the mounting surface 23. That is, the mounting surface 23 faces the base 10 and is located at the bottom of the cover plate 21. The connecting member 22 is connected to the bottom of the cover plate 21 and extends along the circumferential direction of the cover plate 21, so that the connecting member 22 can protrude from the mounting surface 23. When the upper cover 20 is connected to the base 10, the mounting surface 23 is connected to the first surface 11, and the connecting member 22 is inserted into the mounting hole 13, so that part of the connecting member 22 is embedded in the mounting hole 13, and part of the connecting member 22 can be embedded in the buoy 30.

[0049] In this embodiment, the connecting member 22 is connected to the mounting surface 23 and extends along the circumferential direction of the cover plate 21. The connecting member 22 may also have various extension forms, specifically referring to the description in the above-mentioned method 1, and the embodiment of the present invention will not be repeated here.

[0050] It should be noted that the cover plate 21 is connected to the first surface 11, and the connector 22 is embedded in the mounting hole 13. It is necessary to satisfy that the size of the connector 22 is smaller than the size of the mounting hole 13, and the size of the cover plate 21 is larger than the size of the mounting hole 13, so as to avoid the problem that the cover plate 21 also passes through the mounting hole 13 and cannot provide an installation position for the photovoltaic module. The connector 22 is inserted into the mounting hole 13, and part of the connector 22 is embedded in the buoy 30. The matching relationship between the connector 22 and the mounting hole 13 can provide a pre-positioning effect for the installation of the cover plate 21, which is convenient for finding the setting position of the cover plate 21, and can also play a role in limiting the cover plate 21. The movement of the connector 22 in the mounting hole 13 is relatively limited. And part of the connector 22 is embedded in the buoy 30. This part of the connector 22 extends from the mounting hole 13 and extends outward from the base 10. When the buoy 30 is connected, it can play a pre-positioning effect on the buoy 30, which is convenient for finding the setting position of the buoy 30. Similarly, for the connecting member 22, the surface of the connecting member 22 facing the hole wall of the mounting hole 13 can abut against the hole wall of the mounting hole 13, or there can be a certain gap between the surface of the connecting member 22 facing the hole wall of the mounting hole 13 and the hole wall of the mounting hole 13; the part of the connecting member 22 extending into the float 30 can also abut against the inner wall of the float 30, or there can be a gap.

[0051] It should also be noted that when installing the upper cover 20 and the base 10, the connecting piece 22 can be directly embedded in the mounting hole 13, and the mounting surface 23 is abutted against the base 10. At this time, the base 10 can play a blocking and limiting role for the upper cover 20 to prevent the upper cover 20 from moving in the direction from the first surface 11 to the second surface 12; in order to make the connection between the upper cover 20 and the base 10 more stable, glue can also be applied to the part between the mounting surface 23 and the base 10.

[0052] In addition, in some embodiments, Figure 4 , Figure 5 As shown, the float 30 has an installation cavity 32 inside, and an opening 33 is also provided on the float 30. The opening 33 is connected to the installation cavity 32, and the opening of the opening 33 is connected to the second surface 12. A filler 34 can be provided in the installation cavity 32, and the density of the filler 34 is less than the density of the fluid.

[0053] The buoy 30 has an installation cavity 32 inside, and an opening 33 is also provided on the buoy 30. Since the opening 33 is connected to the installation cavity 32, a filler 34 can be placed in the installation cavity 32 through the opening 33. The opening of the opening 33 is connected to the second surface 12, and the second surface 12 of the base 10 can seal the opening of the opening 33 to prevent the fluid from entering the installation cavity 32 through the opening 33 when the floating platform 100 is placed in the fluid, thereby affecting the floating of the floating platform 100. Since the density of the filler 34 is less than the density of the fluid, the filler 34 can increase the buoyancy that the buoy 30 can provide.

[0054] A filler 34 is provided in the float 30, so that even if a float 30 is hit and cracked, when fluid flows into the float 30 through the crack, the filler 34 can also occupy part of the space of the installation cavity 32 to prevent the fluid from completely immersing the installation cavity 32. Moreover, since the density of the filler 34 is less than the density of the fluid, the setting of the filler 34 can also provide additional buoyancy for the float 30, that is, the setting of the filler 34 can ensure that even if fluid enters the installation cavity 32, the floating platform 100 can still float on the fluid, thereby avoiding the problem of failure of the float 30 after the fluid enters the installation cavity 32.

[0055] It should be noted that the filler 34 can be made of different materials with a density less than the fluid. When the fluid is water, seawater, etc., the material of the filler 34 can be polyurethane foam (PU foam), polystyrene foam (Moulded polystyrene foam for thermal insulation, EPS), foam glue, foam concrete, sealed inflatable plastic bags, cement mixed with hollow glass bubbles, etc. The density of these materials is relatively small. Even if cracks occur in the buoy 30 during the application process, causing the fluid to enter the inside of the buoy 30, the setting of the filler 34 can also enable the floating platform 100 to float on the surface of the fluid well, so that the buoy 30 can still provide support for the upper base 10, the upper cover 20, the photovoltaic module, etc. Of course, the filler 34 can also be made of other materials with a density less than the fluid, such as foam board, etc. The specific material of the filler 34 is not specifically limited in the embodiment of the present invention.

[0056] In addition, in order to achieve a better effect of the filler 34 , the density of the filler 34 may be much smaller than the density of the fluid, so that the filler 34 provides a greater buoyancy to the floating platform 100 .

[0057] In addition, in some embodiments, the buoy 30 may include a bottom plate 35 and a plurality of side plates 36, the bottom plate 35 having a mounting surface 37 facing the base 10, the plurality of side plates 36 being connected end to end in sequence, one end of the side plate 36 being connected to the mounting surface 37 and forming a mounting cavity 32 with the mounting surface 37, and the other ends of the plurality of side plates 36 forming an opening 33, the surface on which the side plates 36 are located being an inclined surface, and the inclined surface being inclined in a direction away from the axis of the bottom plate 35, such as Figure 4 , Figure 6 shown.

[0058] The buoy 30 includes a bottom plate 35 and a plurality of side plates 36, and the plurality of side plates 36 are connected end to end in sequence, so that a space with two ends open is formed between the plurality of side plates 36. The bottom plate 35 has a mounting surface 37 facing the base 10, and one end of the side plate 36 is connected to the mounting surface 37, so that the mounting surface 37 can seal an opening of the above space to form a mounting cavity 32, and the filler 34 can be placed in the space between the mounting surface 37 and the plurality of side plates 36. The other ends of the plurality of side plates 36 can form an opening 33, and the filler 34 can be placed in the mounting cavity 32 through the other ends of the side plates 36.

[0059] The surface where the side plate 36 is located is an inclined surface. Since the inclined surface is inclined in a direction away from the axis of the bottom plate 35, the side plate 36 is relatively inclined outward, so that the buoy 30 can be a conical structure with a smaller bottom and a larger top, which is convenient for realizing the stacking packaging of the buoy 30. That is, when multiple buoys 30 are to be transported or stored, the multiple buoys 30 can be stacked up, and one buoy 30 is placed in the installation cavity 32 of another buoy 30, and stacked in sequence, such as Figure 6 When the buoy 30 includes multiple groups of buoy members 31, and the length of each group of buoy members 31 is the same, the buoy members 31 may also include a bottom plate 35 and multiple side plates 36, and the surface of the side plates 36 is an inclined surface, and each group of buoy members 31 may be packed in a stacked manner.

[0060] It should be noted that, in the buoy 30, in order to realize the nested packaging of the buoy 30, the angle between the axis of the side plate 36 and the bottom plate 35 can be 3-5 degrees, specifically 3°, 3.5°, 3.7°, 4.8°, 5°, etc., and the embodiment of the present invention does not specifically limit the degree of inclination of the side plate 36. The axis of the bottom plate 35 is parallel to the direction from the top of the bottom plate 35 to the bottom plate 35, and is parallel to the plumb line.

[0061] It should also be noted that when connecting the float 30 and the base 10, glue can be applied between at least part of the side panel 36 and the base 10 to bond the float 30 and the base 10 together; or, a snap-fitting structure that can cooperate with each other can be provided on the base 10 and the float 30, such as a male buckle and a female buckle, a groove and a protrusion, etc., to snap-fit ​​the float 30 and the base 10 together. The embodiment of the present invention does not specifically limit the connection method between the float 30 and the base 10.

[0062] In addition, in some embodiments, the bottom plate 35 has a bottom surface 38 facing away from the second surface 12 , and the distance between the bottom surface 38 and the second surface 12 may gradually decrease in a direction from the middle of the bottom plate 35 to the edge of the bottom plate 35 .

[0063] The bottom plate 35 has a bottom surface 38 facing away from the second surface 12, and the mounting surface 37 faces the base 10, that is, the bottom surface 38 is opposite to the mounting surface 37. When the floating platform 100 is placed in the fluid, the bottom surface 38 is the farthest part of the buoy 30 from the base 10. Since the distance between the bottom surface 38 and the second surface 12 gradually decreases in the direction from the middle of the bottom plate 35 to the edge of the bottom plate 35, the bottom surface 38 of the buoy 30 is a conical surface, and the distance between the middle of the bottom surface 38 and the second surface 12 is large, and the distance between the edge of the bottom surface 38 and the second surface 12 is small, so that the bottom of the buoy 30 is also a streamlined structure, so that multiple positions at the bottom of the buoy 30 can share the thrust applied by the fluid, which is conducive to improving the hydrodynamic characteristics of the buoy 30 and reducing the hydrodynamic resistance in the horizontal direction.

[0064] In addition, in some embodiments, Figure 2 As shown, the base 10 may include a frame 14, a plurality of first partitions 15 extending along a first direction, and a plurality of second partitions 16 extending along a second direction, the first partition 15 and the second partition 16 are both arranged inside the frame 14, the first partition 15 and the second partition 16 are connected to each other, and both ends of the first partition 15 and the second partition 16 are connected to the inner wall of the frame 14, the upper cover 20 and the float 30 are connected to at least one of the frame 14, the first partition 15, and the second partition 16; the mounting hole 13 includes a first sub-hole 17 and a second sub-hole 18, the first sub-hole 17 is formed by adjacent first partitions 15 and adjacent second partitions 16, and the second sub-hole 18 is formed by the first partition 15, the second partition 16 and the frame 14.

[0065] The base 10 includes a frame 14, a plurality of first partitions 15 extending in a first direction, and a plurality of second partitions 16 extending in a second direction. The first partitions 15 and the second partitions 16 are both arranged inside the frame 14. Since the first partitions 15 and the second partitions 16 are connected to each other, and both ends of the first partitions 15 and the second partitions 16 are connected to the inner wall of the frame 14, the first partitions 15, the second partitions 16, and the inner wall of the frame 14 can divide the inside of the frame 14 to form a plurality of holes. Specifically, adjacent first partitions 15 and adjacent second partitions 16 can enclose a first sub-hole 17, and the first partitions 15, the second partitions 16 and the frame 14 can enclose a second sub-hole 18. The mounting hole 13 includes the first sub-hole 17 and the second sub-hole 18. The upper cover 20 can be connected to at least one of the frame 14, the first partition 15, and the second partition 16, and the float 30 can also be connected to at least one of the frame 14, the first partition 15, and the second partition 16. Part of the upper cover 20 can be inserted into the first sub-hole 17 or the second sub-hole 18, and the upper cover 20 and the float 30 can cover the first sub-hole 17 or the second sub-hole 18.

[0066] For example, at the edge of the base 10, the inner wall of the frame, the first partition 15, and the second partition 16 can be used as the hole wall of the mounting hole 13, and the upper cover 20 here abuts against the frame, the first partition 15, and the second partition 16, and the upper cover 20 can be connected to at least one of them to achieve the connection between the upper cover 20 and the base 10, and the float 30 here also abuts against the frame, the first partition 15, and the second partition 16, and the float 30 can be connected to at least one of them to achieve the connection between the float 30 and the base 10. At other positions of the base 10, two adjacent first partitions 15 and two adjacent second partitions 16 can serve as the hole walls of the mounting hole 13, and the upper cover 20 here is in contact with both the first partition 15 and the second partition 16, and the upper cover 20 can be connected to at least one of them to achieve the connection between the upper cover 20 and the base 10, and the float 30 here is also in contact with both the first partition 15 and the second partition 16, and the float 30 can be connected to at least one of them to achieve the connection between the float 30 and the base 10.

[0067] Among them, the first direction intersects with the second direction, so that the first partition 15 and the second partition 16 can be connected to each other. The first direction intersects with the second direction to form an angle, and the size of the angle can be 90°, 80°, 79°, 85°, 69°, etc. The specific angle between the first direction and the second direction is not specifically limited in the embodiment of the present application.

[0068] In addition, in some embodiments, the upper cover 20 can be any one of ultra-high performance concrete parts, high performance concrete parts, weathering steel parts, and aluminum alloy parts; the buoy 30 can be any one of high-density polyethylene parts, polyvinyl chloride parts, and metal parts.

[0069] The upper cover 20 is any one of ultra-high performance concrete parts, high performance concrete parts, weathering steel parts, and aluminum alloy parts, that is, the upper cover 20 can be made of ultra-high performance concrete, high performance concrete, weathering steel, aluminum alloy and other materials. The upper cover 20 made of these materials has greater strength, toughness and durability, can support the upper photovoltaic components, and resist the impact of typhoons and waves. In addition, it can also withstand ultraviolet radiation to avoid the problem of aging of the upper cover 20 due to ultraviolet radiation. Of course, the upper cover 20 can also be made of other materials, such as marine steel, etc. The material of the upper cover 20 is not specifically limited in the embodiment of the present invention.

[0070] The buoy 30 is any one of a high-density polyethylene part, a polyvinyl chloride part, or a metal part, that is, the buoy 30 can be made of materials such as high-density polyethylene (HDPE), polyvinyl chloride (PVC), and metal. The buoy 30 made of these materials has a relatively low density, can provide buoyancy better, and can make the buoy 30 have good toughness and strength, can resist seawater erosion, and improve the service life of the offshore photovoltaic assembly floating platform 100. In addition, the upper cover 20 on the upper part of the buoy 30 can shield ultraviolet rays, avoid direct contact between the buoy 30 and ultraviolet rays, and can also make the life of the buoy 30 longer. Of course, the buoy 30 can also be made of other materials, and the material of the buoy 30 is not specifically limited in the embodiment of the present invention.

[0071] It should be noted that the base 10 carries the upper cover 20 and the photovoltaic components, and will also be hit by the waves. When multiple floating platforms 100 are arranged on the fluid, the bases 10 of different floating platforms 100 will also collide with each other. Therefore, the base 10 also requires higher strength, and some positions not covered by the upper cover 20 will also be exposed to ultraviolet radiation. Therefore, the material of the base 10 can be the same as that of the upper cover 20, or it can be ultra-high performance concrete, high-performance concrete, weathering steel, aluminum alloy, marine steel, etc.

[0072] In the related art, all parts of the floating platform 100 are designed with the same material, but the main failure modes of the various parts of the floating platform 100 are different. For example, the failure mode of the parts above the fluid surface is mainly material aging caused by ultraviolet radiation, wave impact, collision with each other under the action of wind, waves and currents, etc. The failure mode of the parts below the fluid surface is mainly seawater immersion corrosion, surface cracks seeping into seawater, resulting in a reduction or loss of buoyancy inside the float. In the related art, parts with different failure modes are made of the same material, and different failure modes are not treated differently, which will cause functional mismatch and high cost. However, the present application adopts different materials for different parts, fully considers the failure modes of different parts, sets the materials of each part according to the function and assembles them, and gives full play to the advantages of various materials.

[0073] In the embodiment of the present invention, the floating platform 100 includes a base 10, a plurality of upper covers 20 and a plurality of floats 30. The base 10 has a first surface 11 and a second surface 12 opposite to each other. The base 10 is provided with a plurality of mounting holes 13 extending from the first surface 11 to the second surface 12, and the mounting holes 13 penetrate the base 10. The arrangement of the mounting holes 13 makes the base 10 partially hollow inside, which can reduce the mass of the base 10 and enable the base 10 to float on the fluid. The upper cover 20 is arranged on the first surface 11, and the upper cover 20 is opposite to the mounting hole 13 and covers the mounting hole 13, that is, the upper cover 20 can cover the mounting hole 13, providing an installation position for the photovoltaic module, so that the photovoltaic module can be installed on the floating platform 100 through the upper cover 20. Multiple buoys 30 are connected to the second surface 12, opposite to the mounting hole 13, that is, the upper cover 20 and the buoys 30 are respectively connected to the opposite sides of the base 10, so that when the floating platform 100 is placed in the fluid, the multiple buoys 30 can be located in the fluid and provide buoyancy for the upper base 10, the upper cover 20 and the photovoltaic module. In the present application, the floating platform 100 includes a base 10, multiple upper covers 20 and multiple buoys 30, wherein the buoys 30 are located in the fluid to provide buoyancy, and mainly withstand seawater immersion corrosion; the upper cover 20 and the base 10 carry the photovoltaic module, and withstand the impact of waves, mutual collisions between the floating platforms 100, ultraviolet radiation, etc. These parts can be designed according to their different forces, and the functions of providing buoyancy and anti-collision are decomposed into different components, avoiding the problem of overall consideration of the wind resistance and buoyancy of the floating platform 100 for design, which can simplify the design and structure of the floating platform 100, reduce the difficulty of production and transportation, and the production cost of the floating platform 100.

[0074] In addition, an embodiment of the present invention further provides a water surface floating power station, which includes a photovoltaic module and a floating platform 100 in any of the above embodiments, and the photovoltaic module is installed on an upper cover 20 .

[0075] It should be noted that the floating power station may further include a bracket, the photovoltaic components are mounted on the bracket, and the bracket is mounted on the upper cover 20 , that is, the photovoltaic components may be arranged on the upper cover 20 through the bracket, which may facilitate the connection between the photovoltaic components and the upper cover 20 .

[0076] In addition, in order to make the purpose, technical solution and beneficial effects of the present invention clearer, the assembly steps of the floating platform provided by the embodiments of the present invention are described below to further describe the present invention.

This floating platform requires 5 groups of float parts, and the 5 groups of float parts are divided into type A float parts, type B float parts, type C float parts, type D float parts, and type E float parts according to their lengths. The length of type A float parts is the largest, the length of type B float parts is the second, and the length of type E float parts is the smallest.

[0085] Step 108: After all the buoyancy components are installed, the floating platform is sent into the water pool for a buoyancy test. For the inclination of the upper surface of the floating platform caused by uneven buoyancy, local buoyancy adjustment is performed. After the horizontality of the upper surface of the floating platform meets the requirements and the overall draft depth meets the requirements, the assembly is completed.
