For floating offshore photovoltaics, they are easily affected by the fluctuations of waves, resulting in low conversion efficiency of photovoltaic panels. In addition, when maintenance personnel need to board the floating platform to repair photovoltaic panels, due to the high installation height of the photovoltaic panels, maintenance personnel need to climb, which makes maintenance troublesome.

[0040] like Figure 1-Figure 2As shown, in this embodiment, the floating photovoltaic device includes a floating base 1, a frame 2, a photovoltaic panel 3, a rotating member 4, a telescopic assembly 5, and a detection assembly. The floating base 1 floats on the sea surface, the frame 2 is located above the floating base 1, the photovoltaic panel 3 is mounted on the frame 2, the rotating member 4 is disposed on the frame 2, the fixed end of the telescopic assembly 5 is disposed on the floating base 1, and the telescopic end of the telescopic assembly 5 is connected to the rotating member 4. The detection assembly includes a detection sensor 6 and a control circuit board electrically connected to the detection sensor 6. The detection sensor 6 is mounted on the frame 2 and is used to detect changes in light and sea waves. The control circuit board is used to control the opening or closing of the telescopic assembly 5 and the rotating member 4. Specifically, the floating base 1 is made of a lightweight material with a low density and high porosity, allowing the floating base 1 to float on the sea surface. Floating base 1 is equipped with a telescopic assembly 5, which is an electric telescopic rod 52. Telescopic assembly 5 is located between frame 2 and floating base 1. The telescopic end of telescopic assembly 5 is connected to a rotating member 4, which can be configured as a steering motor or steering gear, and is electrically rotated for angle adjustment. Rotating member 4 is mounted on the bottom of frame 2 and is used to drive the angle rotation of frame 2. Telescopic assembly 5 is used to drive frame 2 to rise and fall vertically relative to floating base 1. Frame 2 is used to fix photovoltaic panels 3, which can adjust their height and inclination angle under the action of rotating member 4 and telescopic assembly 5. Detection sensor 6 integrates multiple sensors, such as wave sensors, human body sensors, and light intensity sensors.

[0041] The operating principle of this floating photovoltaic system is as follows: When the detection sensor 6 detects changes in the solar angle and real-time fluctuations in the ocean waves, it generates a high level signal to the control circuit board, which controls the opening of the rotating member 4. Driven by the rotating member 4, the frame 2 rotates and adjusts its angle, allowing the photovoltaic panel 3 to adjust to the sunlight angle and ocean wave fluctuations, thereby ensuring photovoltaic conversion efficiency. When the detection sensor 6 detects that the solar angle and ocean wave fluctuations remain unchanged, it generates a high level signal to the control circuit board, which controls the closing of the rotating member 4, fixing the angle of the frame 2 and keeping the photovoltaic panel 3 relatively stationary. The detection sensor 6 detects whether a person is on the floating base 1. When the detection sensor 6 detects a person, it generates a high level signal to the control circuit board, which controls the opening of the telescopic assembly 5. Driven by the telescopic assembly 5, the frame 2 rises vertically relative to the floating base 1, allowing inspection personnel to pass smoothly under the photovoltaic panel 3 and facilitate maintenance. When the detection sensor 6 does not detect a person, the detection sensor 6 sends a low level to the control circuit board, and the control circuit board can control the telescopic component 5 to open. Under the driving action of the telescopic component 5, the frame 2 can be lowered to a lower height relative to the floating base 1 in the vertical height direction, reducing the impact of the suction load on the floating photovoltaic device. At the same time, the center of gravity of the entire floating photovoltaic device is lowered, making the entire device more stable under the action of wind and wave flow loads.

[0042] Further, continue to refer to Figure 1-Figure 2 The frame 2 includes a longitudinal beam 21 and a plurality of transverse beams 22. The transverse beams 22 are arranged in parallel and at intervals. The transverse beams 22 are used to mount the photovoltaic panels 3. The longitudinal beams 21 are sequentially connected to the bottoms of the plurality of transverse beams 22. Specifically, the transverse beams 22 and the longitudinal beams 21 can both be configured as slats. The longitudinal beams 21 and the plurality of transverse beams 22 constitute the frame 2 for securing the plurality of photovoltaic panels 3, providing a stable structure. Optionally, there are multiple longitudinal beams 21. The plurality of longitudinal beams 21 are arranged in parallel and at intervals along the length of the transverse beams 22, allowing the frame 2 to extend in the same direction to secure a larger number of photovoltaic panels 3.

[0043] Further, continue to refer to Figure 1-Figure 2The telescopic assembly 5 includes a fixed column 51 and an electric telescopic rod 52. The fixed column 51 is mounted on the floating base 1. The fixed end of the electric telescopic rod 52 is connected to the fixed column 51, and the telescopic end of the electric telescopic rod 52 is connected to the rotating member 4. Specifically, the fixed column 51 is fixedly mounted in the mounting hole of the floating base 1 and secured by bolts. When the detection sensor 6 detects a person, the detection sensor 6 generates a high level signal to the control circuit board, which controls the electric telescopic rod 52 to open, allowing the frame 2 to vertically rise relative to the floating base 1 to allow inspection personnel to pass smoothly under the photovoltaic panels 3, facilitating maintenance. When the detection sensor 6 does not detect a person, the detection sensor 6 generates a low level signal to the control circuit board, which controls the electric telescopic rod 52 to open, allowing the frame 2 to vertically descend relative to the floating base 1 to a lower height, thereby reducing the impact of wind loads on the floating photovoltaic system.

[0044] Further, continue to refer to Figure 1-Figure 2 The floating base 1 includes a plurality of floating plates 11 and connectors 12. The plurality of floating plates 11 are sequentially connected along a first direction, with each adjacent floating plate 11 connected via a connector 12. Specifically, the first direction is the AB direction. The connector 12 is configured as a rigid connector and includes a first fixing portion and a second fixing portion. The first fixing portion is fixedly connected to one of the adjacent floating plates 11, and the second fixing portion is fixedly connected to the other adjacent floating plate 11. The first fixing portion and the second fixing portion are welded together, that is, the adjacent floating plates 11 are connected via the first fixing portion and the second fixing portion. This allows the floating base 1 to better float on the sea surface while supporting the frame 2 and the photovoltaic panel 3, preventing wind and waves from blowing the floating base 1 apart. Preferably, there are multiple connectors 12, and the multiple connectors 12 are spaced apart along a second direction, which is perpendicular to the first direction and is the CD direction. The adjacent floating plates 11 are connected via the multiple connectors 12 spaced apart along the second direction, providing a more stable connection and preventing the floating plates 11 from detaching and affecting the normal use of the photovoltaic panel 3.

[0045] Further, continue to refer to Figure 1-Figure 2 The floating photovoltaic system also includes a hydrogen production system 7 and an oxygen production system 8, both of which are mounted on the floating base 1 and electrically connected to the photovoltaic panels 3. Specifically, the photovoltaic panels 3 convert solar energy into electrical energy and store it. The hydrogen production system 7, the oxygen production system 8, and the photovoltaic panels 3 then generate electricity to electrolyze seawater to produce hydrogen and oxygen.

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.
