[0002] Solar energy, with its abundant resources, widespread distribution, renewable nature, and pollution-free nature, is an ideal clean energy source. While the photovoltaic power generation industry is rapidly developing, land resources are increasingly limiting traditional land-based photovoltaic power plants. Consequently, floating photovoltaic power generation has emerged as a new form of photovoltaic power generation.

[0003] Floating photovoltaic power generation refers to the construction of floating photovoltaic systems in water environments such as ponds, reservoirs, lakes and sea surfaces. It can effectively and comprehensively utilize water bodies and solve the shortcomings of traditional photovoltaic power generation that it occupies a large area.

[0034] In addition, the terms "first", "second", etc. are only used to distinguish in description and have no special meaning.

[0035] See also Figures 1 to 4 As shown, this embodiment provides a floating photovoltaic system, including a floating base 1, a photovoltaic bracket 2 and a photovoltaic module 3, wherein:

[0036] The floating body base 1 includes a plurality of floating body groups 11 distributed in rows. Each floating body group 11 includes a plurality of floating body units 111 distributed in columns. The floating body units 111 are cylindrical. The floating body units 111 of two adjacent rows of floating body groups 11 are connected to each other at their ends.

[0037] The photovoltaic support 2 is installed on one or more floating body groups 11. The photovoltaic support 2 includes a base frame 21. The base frame 21 is mounted on at least two floating body units 111 in one floating body group 11. The base frame 21 is provided with a clamp 22 for clamping the contacting floating body units 111.

[0038] Several photovoltaic modules 3 are installed on the photovoltaic support 2 .

[0039] Therefore, the floating photovoltaic system is designed with a cylindrical floating unit 111 and the assembly structure of the floating unit 111 and the photovoltaic module 3 is optimized, which not only achieves the purpose of effectively dispersing the impact force of the waves, but also ensures the reliable installation of the photovoltaic module 3, thereby improving the stability and impact resistance of the overall structure to cope with various water environment influences and ensure the normal operation of the floating photovoltaic system.

[0040] Specifically, in this embodiment, six floating unit elements 111 are arranged in two rows and three columns as an example to form two floating body groups 11. A photovoltaic bracket 2 is installed on each floating body group 11. A photovoltaic bracket 2 includes two base frames 21. The two base frames 21 are simultaneously erected on the three floating unit elements 111 in a row. Four photovoltaic modules 3 are installed on one photovoltaic bracket 2, thereby ensuring the laying of eight photovoltaic modules 3.

[0041] On this basis, the area of ​​the floating base 1 can be infinitely expanded, and the number of photovoltaic brackets 2 and the contact position with the floating base 1 can also be adjusted according to the laying requirements and stability requirements of the photovoltaic components 3.

[0042] Optionally, the floating unit 111 includes a floating tube 1111, and the two ends of the floating tube 1111 are respectively connected to a hemispherical adapter 1112. A connecting piece 12 is provided between the adapter 1112 of one floating unit 111 and the adapter 1112 of another floating unit 111 to ensure reliable connection between adjacent floating body groups 11.

[0043] Specifically, the connector 12 includes a connecting ring 121. Each adapter 1112 is provided with a connecting ring 121. The connecting rings 121 of two opposing floating unit elements 111 engage with each other. The connecting rings 121 should be capable of quick assembly and disassembly to meet the connection requirements between the floating unit elements 111. However, this connection is not limited to this type of connection; other connectors 12 may also be used.

[0044] Furthermore, the connecting ring 121 is provided with a screw portion 122 that screws into the adapter 1112. The screw portions 122 of the two connecting rings 121 of each floating unit 111 are connected by a cable 123, which ensures that the adapters 1112 at both ends are tightly pressed against the floating tube 1111. In addition, the floating tube 1111 and the adapter 1112 are designed to be plug-in and snap-fit. The presence of the cable 123 prevents the original fitting of the floating tube 1111 and the adapter 1112 from disassembling, thus further stabilizing the structure of the floating unit 111.

[0045] Furthermore, the outer cover of the connector 12 is provided with an anti-collision block 13, which abuts against the adapter 1112 at both ends, thereby forming a buffer between the two floating unit components 111, avoiding violent collisions between the floating unit components 111 when the wind and waves are strong, extending the service life of the connector 12, and ensuring the structural stability of the floating base 1.

[0046] Optionally, according to the shape of the floating unit 111, which is the shape of the floating tube 1111 here, the clamp 22 is U-shaped, the curved portion of the clamp 22 fits the surface of the floating tube 1111, and the two ends of the clamp 22 are respectively fixed to the base frame 21 by bolts, thereby reliably fixing the floating unit 111 and the base frame 21 as a whole.

[0047] Optionally, a limiting groove 1113 is provided on the surface of the floating unit 111 corresponding to the installation position of the base frame 21, which effectively prevents the floating unit 111 from rotating after being bound to the base frame 21, thereby further improving the stability of the floating base 1 and the photovoltaic bracket 2 after assembly.

[0048] Optionally, the photovoltaic bracket 2 also includes a column 23 arranged on the base frame 21, a diagonal brace 24 is arranged between the column 23 and the base frame 21, a side pressure block 25 is arranged on the top of the column 23, and a bottom support block 26 is arranged on the base frame 21. One side of the photovoltaic component 3 is supported by the bottom support block 26, and the other side of the photovoltaic component 3 is pressed by the side pressure block 25, so that the photovoltaic component 3 is fixed on the photovoltaic bracket 2 at an angle.

[0049] Specifically, a slot is provided on the top edge of the base frame 21, and an undercut 261 is provided on the bottom support block 26. This undercut 261 prevents the bottom support block 26 from slipping out or moving once inserted into the slot. During installation, after securing the uprights 23, the position of the bottom support block 26 is determined based on the size and tilt angle of the photovoltaic module 3, and the bottom support block 26 is pressed into the slot.

[0050] Furthermore, the bottom support block 26 is provided with a bearing portion 262, a side stop 263, and an upper pressing portion 264, which are exposed from the slot. The bearing portion 262 abuts against the lower edge surface of the photovoltaic module 3, the side stop 263 abuts against the side edge surface of the photovoltaic module 3, and the upper pressing portion 264 abuts against the upper edge surface of the photovoltaic module 3. The side stop 263 and the upper pressing portion 264 are integrally bent from the bearing portion 262. In particular, the side stop 263 and the upper pressing portion 264 have a certain degree of elastic deformation to facilitate the installation of the photovoltaic module 3 and absorb some impact force.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments 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.
