[0002] By setting up photovoltaic arrays at sea and arranging artificial fish reefs in the waters below for aquaculture, a new "photovoltaic-fishery complementary" model of "generating electricity above and raising fish below" can be formed, which not only saves energy but also improves the efficiency of aquaculture. In the case of applications at a water depth of about 30 meters, existing offshore photovoltaic platforms generally have problems such as complex structure, high construction requirements, and high investment costs. For offshore photovoltaic-fishery complementary platforms with simple requirements, the photovoltaic on the platform does not require personnel on duty, and the artificial fish reefs below the platform do not require maintenance, and the function is single. Therefore, there is an urgent need for an offshore photovoltaic-fishery complementary platform with a simple structure, convenient construction, and low investment cost. Summary of the invention

[0009] Furthermore, a plurality of support pipes that are spread out in all directions in an umbrella shape are arranged on the top of the main column; and the top of the support pipes is connected to the bottom of the upper platform.

[0010] Furthermore, the upper platform includes a plurality of straight steel pipes intersectingly arranged with a spherical node as the intersection center, and a plurality of annular steel pipes with the spherical node as the center and fixed on each straight steel pipe in a concentric circle distribution.

[0011] Furthermore, the photovoltaic panel is installed in a fan-shaped area composed of straight steel pipes and circular steel pipes.

[0023] See also Figure 1~Figure 4 The utility model relates to an offshore photovoltaic-fishing complementary platform, comprising an upper platform 2 for laying out and installing a photovoltaic panel 1, a barrel-shaped foundation 3 installed on the seabed, a support pipe rack fixed on the barrel-shaped foundation 3 and providing support for the upper platform 2, and a cylindrical artificial fish reef 4 mounted on the support pipe rack;

[0024] The upper platform 2 includes a plurality of straight steel pipes 22 intersectingly arranged with a spherical node 21 as the intersection center, and a plurality of annular steel pipes 23 with the spherical node 21 as the center and fixed on each straight steel pipe 22 in a concentric circle distribution; specifically, the upper platform 2 is spliced ​​into a single-layer frame by straight steel pipes 22 and annular steel pipes 23, and the straight steel pipes 22 and annular steel pipes 23 support each other in the horizontal direction, and the central position steel pipes alternately use a spherical node 21; the photovoltaic panel 1 is installed in a fan-shaped area composed of straight steel pipes 22 and annular steel pipes 23; the upper platform 2 is at a certain height above the sea level of the high tide level to ensure that the seawater diameter can be avoided under extreme sea conditions. The photovoltaic panel 1 is erected above the water surface, which can effectively block the water surface from absorbing solar radiation, thereby reducing the water temperature. This cooling effect is not only beneficial to aquaculture, but also can improve the power generation efficiency of solar panels, thereby providing more clean energy. In addition, the upper platform 2 is also equipped with battery energy storage facilities. The photovoltaic panels and batteries can alternately power the facilities on the platform, eliminating the need for additional power. When the sun is shining, the photovoltaic panels are used to generate electricity and charge the batteries at the same time. When there is no sun, the batteries are used to supply power, reducing the operating costs of the platform.

[0025] The barrel foundation 3 is a suction barrel structure, which is embedded into the seabed by absorption. Marine platforms with suction barrel foundation are widely used in shallow waters of 20-40m. They do not require large-scale construction resources such as floating cranes. The technology is mature, the installation is convenient, and the cost is low. Therefore, the utility model adopts a suction barrel foundation, which is embedded into the seabed to a certain depth by absorption, providing sufficient mooring force for the photovoltaic platform, which can effectively resist horizontal and vertical loads. The application technology is mature, and it has the advantages of easy installation, low cost, and small space occupation.

[0026] The supporting pipe rack comprises a main pipe column 5 whose bottom is fixed on the top of the barrel foundation 3, and a plurality of supporting pipes 7 are arranged on the top of the main pipe column 5 and spread out in an umbrella shape. The top of the supporting pipe 7 is connected to the bottom of the upper platform 2 to provide support for the upper platform 2; a supporting frame 6 is arranged on the pipe body of the main pipe column 5, and the supporting frame 6 comprises a plurality of ribs 61 evenly distributed on the vertical outer circumference of the main pipe column 5, and a plurality of ribs 62 horizontally arranged on the ribs 61 to enhance the structural strength;

[0027] The artificial fish reef 4 is a steel cylindrical structure, and a plurality of through holes 41 are opened on the cylinder wall. The hole design has a diversion effect, reduces the impact of ocean currents, increases structural stability, and facilitates the entry of marine life into the fish reef. The cylinder of the artificial fish reef 4 is sleeved on the outer ends of the ribs 61 of the support frame 6. A plurality of large-area ribs 61 are used to connect the main column 5 and the artificial fish reef 4. The large-area ribs 61 and the plurality of ribs 62 can greatly increase the effective attachment area of ​​the internal space of the fish reef, which is beneficial to fishery breeding.

[0028] The offshore photovoltaic-fishing complementary platform does not require personnel on duty and has a single functional requirement. The utility model combines the mature suction bucket form foundation with the support form of the main column 5 combined with the support pipe 7, and arranges artificial fish reefs 4 on the main column 5. The annular frame upper platform 2 spliced ​​by straight steel pipes 22 and annular steel pipes 23 has a simple overall structure and is easy to install, which can effectively reduce the investment cost of offshore photovoltaic projects.

[0029] Application case: water depth 25m, suction bucket with 5m diameter, 7m depth into the seabed; main column with 2m diameter and 50mm wall thickness; 4 support pipes are distributed at 90 degrees, with a horizontal distance of 10m between the top center of the support pipe and the center of the main column, and 0.3m diameter and 20mm wall thickness; the upper platform elevation +6m, circular plate shape, the straight steel pipes of the platform frame are cross-arranged with 325X20 circular pipes, the central node is in the form of a sphere, and the area is 450m 2 , according to 200W / m 2 The unit installed capacity of the photovoltaic panel can achieve an installed capacity of 90KW; the steel fish reef cylinder is 20m high, with a 20m diameter and 30mm wall thickness, and multiple 2m diameter through holes are opened on the cylinder wall; 6 ribs are distributed at 60 degrees, with a height of 20m, a wall thickness of 25mm, and a horizontal span of 9m. Ribs are arranged on the ribs to strengthen the ribs.
