For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] The present invention provides an offshore floating photovoltaic pontoon support with a wing plate, comprising a floating platform and a photovoltaic module, wherein the photovoltaic module is arranged on the floating platform, a pontoon mechanism is arranged at the bottom of the floating platform, and adjacent floating platforms are connected by flexible connectors, wherein the pontoon mechanism comprises a pontoon body, a pontoon body upper and lower floating adjustment device, and a pontoon body horizontal displacement adjustment device, wherein the pontoon body is arranged at the bottom of the floating platform, and the pontoon body is provided with the pontoon body upper and lower displacement adjustment device and the pontoon body horizontal displacement adjustment device, so that when the pontoon body encounters an ocean current, the pontoon body upper and lower displacement adjustment device and the pontoon body horizontal displacement adjustment device simultaneously act to generate a force opposite to the direction of the ocean current, thereby preventing the pontoon body from drifting and sinking. The present invention solves the problem of fixed connection between floating platforms, wherein the propeller and the wing plate simultaneously act to generate a force opposite to the direction of the ocean current, thereby improving the stability of the floating platform during operation, thereby preventing the floating platform from drifting and sinking.

[0024] The entire technical process is described in detail below using an offshore floating photovoltaic buoy bracket with wing plates as an example.

[0025] like Figure 1 As shown, an offshore floating photovoltaic pontoon support with wing plates includes a floating platform 1 and a photovoltaic module 7. A plurality of photovoltaic modules 7 are fixedly connected to the floating platform 1 at equal intervals. A pontoon mechanism is provided at the bottom of the floating platform 1. Furthermore, the pontoon mechanism is arranged at the center of the bottom surface of the floating platform 1. Adjacent floating platforms 1 are connected by flexible connectors 10.

[0026] like Figure 1 and Figure 2 As shown, the buoy mechanism includes a buoy body 2, a buoy body up and down adjustment device and a buoy body horizontal displacement adjustment device. The buoy body 2 is arranged at the bottom of the floating platform 1, and the buoy body up and down displacement adjustment device and the buoy body horizontal displacement adjustment device are provided on the buoy body 2, so that when the buoy body 2 encounters an ocean current, the buoy body up and down displacement adjustment device and the buoy body horizontal displacement adjustment device simultaneously act to generate a force opposite to the direction of the ocean current, thereby preventing the buoy body 2 from drifting and sinking.

[0027] like Figure 4-1 , Figure 4-2 and Figure 4-3 As shown, the buoy body up and down displacement adjustment device includes a wing plate 8 and a connecting shaft 12. The cross-section of the wing plate 8 is a double-convex airfoil. The wing plate 8 is installed on the outer wall of the buoy body 2 through the connecting shaft 12. The wing plate 8 can rotate around the connecting shaft 12.

[0028] The wing plate 8 includes a free end 8-1 and a connecting end 8-2. Figure 4-2 In the direction of the middle II plane), the thickness of the wing plate 8 gradually decreases, the cross-sectional length of the wing plate 8 gradually increases, and each wing plate 8 can move independently, and the connecting end 8-2 is installed on the outer wall of the buoy body 2 through the connecting shaft 12. Preferably, the connecting end 8-2 is arranged on the circumference of the middle upper part of the outer wall of the buoy body 2 through the connecting shaft 12.

[0029] The wing plate 8 receives the command of the control system to adjust its angle, so that the head end 8-3 of the wing plate 8 faces the ocean current at different angles. By changing the speed of the fluid flowing through the wing plate 8, an upward buoyancy or downward force is generated on the buoy body 2. At the same time, by adjusting the angles of the wing plates 8, the force size and direction of the buoy body 2 are changed, thereby adjusting the posture of the buoy body 2.

[0030] like Figure 1As shown, the buoy body horizontal displacement adjustment device is a propeller 9 arranged at the center of gravity of the buoy body 2. The propeller 9 is installed at the center of gravity of the buoy body 2, and the installation direction of the propeller 9 is consistent with the main flow direction of the ocean current. The propeller 9 can rotate forward or reverse, and each propeller 9 can act independently.

[0031] The propeller 9 and the wing plate 8 act simultaneously to generate a force opposite to the direction of the ocean current, thereby preventing the floating platform 1 from drifting and sinking and improving the stability of the floating platform 1 during operation.

[0032] like Figure 3 As shown, a plurality of flexible connectors 10 are fixedly connected between two adjacent floating platforms 1 at equal intervals, and the flexible connector 10 includes an outer spring 13, an inner spring 14, a first connector 15, and a second connector 16. The outer spring 13 is arranged outside the inner spring 14, and the head 13-1 of the outer spring is connected to the tail 14-2 of the inner spring through the first connector 15, and the tail 13-2 of the outer spring is connected to the head 14-1 of the inner spring through the second connector 16. Further, the head 13-1 of the outer spring and the first connector 15, the first connector 15 and the tail 14-2 of the inner spring, the tail 13-2 of the outer spring and the second connector 16, and the second connector 16 and the head 14-1 of the inner spring are fixed by bolts 17, respectively.

[0033] The flexible connector 10 is fixedly connected between two adjacent floating platforms 1 at equal intervals, so that the connection between the floating platforms 1 is more stable and firm. At the same time, the flexible connector 10 is a double-layer spring structure, which enhances the ability of the spring to absorb deformation and displacement.

[0034] Multiple floating platforms 1 float on the sea surface through the buoy mechanism, and the floating platforms 1 are connected by multiple flexible connectors 10. When the floating platforms 1 are displaced by waves of different frequencies, the flexible connectors 10 can absorb part of the force between the platforms through their own deformation. That is, when adjacent floating platforms 1 are close to each other, the outer spring 13 is compressed and the inner spring 14 is stretched; when adjacent floating platforms 1 are away from each other, the outer spring 13 is stretched and the inner spring 14 is compressed. When the floating platform is tilted by external force, the flexible connector 10 can enable the floating platform 1 to move the buoyancy center to achieve its self-centering effect, thereby improving the stability of the floating platform 1 during operation.

[0035] The buoy mechanism also includes a connection part and a buoy base 3. The bottom of the floating platform 1 is fixedly connected and communicated with the buoy body 2 through the connection assembly. The bottom of the buoy body 2 is fixed and communicated with the buoy base 3. The buoy base 3 is provided with an energy storage battery compartment 4 inside. The energy storage battery compartment 4 is provided with an energy storage battery. The buoy base 3 is semi-spherical. Preferably, the energy storage battery compartment 4 is arranged at the bottom inside the buoy base 3, that is, the energy storage battery is arranged in a semi-spherical position, and the gravity point moves downward, which effectively creates a suspension effect to maintain the uprightness of the buoy mechanism.

[0036] like Figure 2 As shown, the connection part includes a connection pipe 6, a first connection seat 5 and a second connection seat 11. The bottom of the floating platform 1 is fixed to the first connection seat 5. The first connection seat 5 is connected through one end of the connection pipe 6. The other end of the connection pipe 6 is fixedly connected and communicated with the second connection seat 11. The second connection seat 11 is fixedly connected and communicated with the buoy body 2. In addition, a ladder is provided in the connection pipe 6 to facilitate operators to enter the buoy body 2 and the buoy base 3 for operation.

[0037] Among them, the number of first connecting seats 5 is preferably 3, and the angle between two adjacent first connecting seats 5 is 120°, which improves the stability of the connection between the buoy body 2 and the floating platform 1, while reducing the impact of the ocean current near the sea level on the bracket, and the structure is more stable.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
