Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, and in particular to an offshore annular floating photovoltaic bracket that can be used for fish farming. Background Art

[0002] Currently, existing offshore floating supports are composed of floats and steel components, and are used for photovoltaic power generation. This structure of the support can improve the wind and wave resistance of the offshore part of the support structure. However, when combined with fish farming cages, the connection between the network cable and the steel component is easily worn under the action of wind and waves, and the service life is relatively short. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an offshore annular floating photovoltaic bracket that can be used for fish farming and has the effect of resisting sea waves.

[0004] An offshore annular floating photovoltaic support that can be used for fish farming includes a central float, a rigid inner ring, a flexible outer ring, several connecting cables, a supporting float, a mounting frame, and a cage. The central float is connected to the rigid inner ring by connecting cables, which are arranged radially. The supporting float and the mounting frame are respectively mounted on the connecting cables. The mounting frame is used to install photovoltaic panels. The rigid inner ring and the flexible outer ring are connected by a connector. The flexible outer ring is mounted with a cage, which is used for fish farming.

[0005] Preferably, the central floating body includes a buoy, a rigid ring is installed on the buoy, a plurality of connecting rope fixing rings are installed on the rigid ring, the connecting rope fixing rings are evenly distributed on the rigid ring, the number of the connecting rope fixing rings is consistent with the number of the connecting ropes, and the connecting rope fixing rings are used to fix the connecting ropes.

[0006] Preferably, the rigid ring includes an upper ring and a lower ring, and the upper ring and the lower ring are connected by a plurality of columns. The columns are evenly distributed on the upper ring or the lower ring, and two connecting rope fixing rings are installed on each column.

[0007] Preferably, the connecting cables are in groups of two, and each group of connecting cables is arranged in parallel. One end of each group of connecting cables is fixed to the central float, and the other end is fixed to the rigid inner ring. A number of supporting floats and a number of mounting frames are evenly installed on each group of connecting cables. The mounting frames include a first supporting purlin and a second supporting purlin. The first supporting purlin and the second supporting purlin are arranged in parallel between the two connecting cables. A longitudinal support rod is installed on the second supporting purlin, and a photovoltaic panel is installed between the first supporting purlin and the longitudinal support rod.

[0008] Preferably, a handrail column is installed on the connecting piece, and a circular handrail is installed on the handrail column.

[0009] Preferably, the connecting rope is a steel rope.

[0010] Preferably, the supporting float is fixedly connected to the two connecting ropes in each group through two U-shaped connecting pieces.

[0011] The beneficial effects of the utility model are:

[0012] 1. The bracket adopts a double-ring structure with a rigid inner ring and a flexible outer ring. The double-ring structure is connected to the central floating body by prestressed steel cables. The outer ring is a flexible structure, and the inner central floating body is a rigid structure. The structural technology of combining rigidity and flexibility enables the entire ring to achieve sufficient rigidity to withstand sea waves.

[0013] 2. The cables are supported by multiple buoyant supports along the tensioning direction. The buoyancy of these supports keeps the cables above sea level. Once the PV panels are installed on the cables, the entire array is above sea level. The cables are radially spaced at designated intervals throughout the PV array. Once the panels are installed, a gap is created between adjacent spans to mitigate the impact of waves.

[0014] 3. The fish farming area is located below the sea level in the photovoltaic zone, fully utilizing the site's footprint. The gaps between the photovoltaic panels in the photovoltaic zone leave ample space for various operations in the fish farming area, creating a complementary model of power generation above sea level and fish farming below sea level, effectively and efficiently utilizing space resources.
