DETAILED DESCRIPTION

[0030] In view of this, the core of the present invention is to provide a floating platform to reduce the manufacturing cost of the floating platform and shorten the construction period.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, an embodiment of the present invention discloses a floating platform, including edge pontoons 100 , a central pontoon 200 and an arched truss 300 .

[0033] Among them, there are multiple edge buoys 100, and the center points of the multiple edge buoys 100 are connected end to end in sequence to form a closed figure; the central buoy 200 is located at the center of the closed figure; the arch truss 300 includes a central support column 301, multiple edge support columns 302 and multiple connecting rods 303, the central support column 301 is arranged on the central buoy 200, and the edge support columns 302 are arranged on the corresponding edge buoys 100, and the multiple connecting rods 303 radiate outward from the center of the central support column 301 and are connected to the corresponding edge buoys 100, the connection position of the connecting rod 303 and the central support column 301 is set as the central connection position, and the connection position of the connecting rod 303 and the edge buoy 100 is set as the edge connection position, and the height of the central connection position is higher than the height of the edge connection position.

[0034] When the floating platform provided by the present invention is used, the center points of the multiple edge buoys 100 are connected end to end in sequence to form a closed figure, the central buoy 200 is located at the center of the closed figure, the central support column 301 is set on the central buoy 200, and the edge support column 302 is set on the corresponding edge buoy 100. A plurality of connecting rods 303 radiate outward from the center of the central support column 301 and are connected to the corresponding edge buoy 100, and the height of the central connection position is higher than the height of the edge connection position. Therefore, through the central support column 301, the edge support column 302 and the edge support column 303 are connected to the corresponding edge buoy 100. The support columns 302 and the connecting rods 303 can form an arched truss 300 in a three-dimensional space, and the photovoltaic panels 400 are supported by the arched truss 300, and buoyancy is provided by the edge pontoons 100 and the central pontoon 200 at the bottom of the arched truss 300. It can be seen that the floating platform provided by the present invention replaces the traditional square truss with the arched truss 300 with an arched structure in a three-dimensional space, thereby fully utilizing the spatial force transmission path and reducing the amount of steel used. As the amount of steel used is reduced, the manufacturing cost of the floating platform can be reduced and the construction period can be shortened.

[0035] It should be noted that the present invention does not impose specific restrictions on parameters such as the number and size specifications of the above-mentioned edge buoys 100. As long as the parameters can meet the buoyancy requirements of the floating platform, they are within the protection scope of the present invention; optionally, in a specific embodiment of the present invention, the number of edge buoys 100 is four, namely the first edge buoy, the second edge buoy, the third edge buoy and the fourth edge buoy, and the center points of the first edge buoy, the second edge buoy, the third edge buoy and the fourth edge buoy are connected end to end in sequence to form a square, and the center buoy 200 is located at the center of the square.

[0036] In addition, the arched truss 300 also includes an arched connecting beam 304 and a connecting support rod 305 connecting the arched connecting beam 304 and the central support column 301.

The connection position between the arched connecting beam 304 and the connecting support rod 305 is a beam connection position. The height of the beam connection position is higher than the edge connection position and lower than the height of the center connection position, so that the arched structure forms an eggshell-shaped structure in three-dimensional space, further improving the bearing capacity of the floating platform.

[0037] It should be understood that the above-mentioned arched connecting beam 304 can be an integrally formed arched structure, or an arched structure formed by connecting at least two support beams. As long as the structural form facilitates the above-mentioned arched truss 300 to form an eggshell-shaped structure in three-dimensional space, it falls within the scope of protection of the present invention.

Any structure that can meet the use requirements falls within the scope of protection of the present invention.

[0039] Furthermore, the arched truss 300 further includes support connection columns 306 , so as to connect the arched connection beams 304 and the photovoltaic panels 400 via the support connection columns 306 .

[0040] It should be understood that the present invention does not impose any specific restrictions on parameters such as the number and diameter of the supporting connecting columns 306 . As long as the parameters can meet the mechanical performance requirements, they fall within the protection scope of the present invention.

[0041] like Figures 1 to 4 As shown, in a specific embodiment of the present invention, the supporting connecting column 306 and the edge supporting column 302 are both height-fixing rods, and the top heights of the supporting connecting column 306 and the edge supporting column 302 are flush with the top height of the center supporting column 301, so as to form a horizontal mounting surface on the arch truss 300, and the photovoltaic panel 400 is installed on the horizontal mounting surface to fix the photovoltaic panel 400.

[0042] Furthermore, if Figures 5 and 6As shown, in another specific embodiment of the present invention, the support connecting column 306 and the edge support column 302 are both height-fixed rods, and the top heights of the support connecting column 306 and the edge support column 302 are both lower than the top height of the center support column 301, so as to form an inclined mounting surface on the arch truss 300, and the photovoltaic panel 400 is installed on the inclined mounting surface, so that in snowy weather, the snow on the photovoltaic panel 400 can automatically slide down under its own weight, and there is no need to manually clean the snow, thus saving manpower.

[0043] Furthermore, if Figures 7 and 8 As shown, the support connecting column 306 and the edge support column 302 are both lifting adjustment rods, so as to adjust the inclination of the inclined installation surface by adjusting the height of the support connecting column 306 and the edge support column 302, thereby facilitating the adjustment of the inclination of the photovoltaic panel 400 and expanding the scope of application of the floating platform.

[0044] It should be understood that the above-mentioned lifting adjustment rod can be a hydraulic lifting rod, a pneumatic lifting rod or an electric lifting rod, etc. As long as the type can meet the use requirements, it falls within the protection scope of the present invention.

[0046] In addition, the present invention also discloses an offshore floating photovoltaic system, including a photovoltaic panel 400 and the floating platform as described above. The photovoltaic panel 400 is arranged on the arch truss 300 of the floating platform. Since the offshore floating photovoltaic system includes the floating platform as described above, it has all the technical effects of the above-mentioned floating platform, which will not be described in detail here.
