[0022] See also Figure 1~Figure 5 The utility model relates to an offshore photovoltaic support structure, comprising a support platform 2 for laying out and installing a photovoltaic panel 1, a barrel-shaped foundation 3 installed on the seabed, and a support pipe rack fixed on the barrel-shaped foundation 3 and providing support for the support platform 2;

[0023] Marine oil and gas platforms with suction bucket foundations are widely used in shallow waters because they usually do not require the use of large construction resources such as floating cranes. They are easy to install, low in cost, and take up little space. Especially for marginal oil and gas platforms that require simplicity, due to investment restrictions, suction bucket foundations are more widely used. The barrel-shaped foundation 3 of the utility model is a suction bucket structure, which uses the suction bucket to absorb and embed into the seabed to a certain depth, providing sufficient mooring force, and can effectively resist horizontal and vertical loads. The application technology is mature and has the advantages of easy installation, low cost, and small space. A depth mark 6 is provided on the outer shell of the suction bucket to indicate the depth of the suction bucket embedded in the seabed, which is convenient for confirming that the installation is in place during construction;

[0024] The support pipe rack comprises a main pipe column 4 whose bottom is fixed on the top of the barrel foundation 3, and a plurality of support pipes 5 arranged on the top of the main pipe column 4 and spread out in an umbrella shape. Specifically, four support pipes 5 are arranged on the top of the main pipe column 4 of this embodiment, and the top of each support pipe 5 is connected to the bottom of the support platform 2 to provide support for the support platform 2. The main pipe column 4 is combined with the support pipe 5 to provide support, which has a simple structure, is easy to manufacture, and has a low cost.

[0025] Since the support pipe rack and suction bucket foundation below the sea level occupy a small space, more support platforms 2 can be arranged in a limited sea area, thereby increasing the density of photovoltaic panels 1, improving the utilization rate of the sea area, and increasing photovoltaic power generation;

[0026] The support platform 2 comprises a field-shaped frame 7 formed by splicing a plurality of main steel sections, and a plurality of support steel sections 8 arranged in parallel in the field-shaped frame 7; the top of the support pipe 5 is connected to the main steel sections inside the field-shaped frame 7 to provide support; the photovoltaic panel 1 is installed on the top surface of the main steel sections and the support steel sections 8 through the support column 9; the support platform 2, which is spliced ​​into a frame structure, has a simple structure, good strength, high reliability and low cost;

[0027] Offshore photovoltaics do not require personnel on duty and have a single functional requirement. The utility model combines the mature technology of the suction bucket form foundation, adopts the support form of the main column 4 combined with the support pipe 5, and the frame-type support platform 2 spliced ​​by steel sections. The overall structure is simple and easy to install, which can effectively reduce the investment cost of offshore photovoltaic projects.
