[0056] Reference Figures 1 to 7 The present invention provides a photovoltaic floating platform 100 with an adjustable center of gravity, comprising:

[0057] buoy 10;

[0058] The tilt sensor 20 is provided on the top of the buoy 10 and is used to detect the tilt of the buoy 10;

[0059] a carrying platform 30, which is sleeved on the outer circumferential surface of the pontoon 10 and can be raised and lowered in the axial direction of the pontoon 10; an installation space 33 is formed inside the carrying platform 30; the side of the carrying platform 30 facing the inclination sensor 20 can be opened or closed to connect or separate the installation space 33 from the outside; the inclination sensor 20 is connected to the carrying platform 30 to open, close, and raise or lower the carrying platform 30 in the axial direction of the pontoon 10 according to the indication of the inclination sensor 20; and

[0060] The photovoltaic system 40 is installed in the installation space 33 .

[0061] The adjustable-center-of-gravity photovoltaic floating platform 100 of the present invention comprises a buoy 10, an inclination sensor 20, a supporting platform 30, and a photovoltaic system 40. When environmental loads such as wind, waves, and currents significantly impact the adjustable-center-of-gravity photovoltaic floating platform 100, the inclination sensor 20 detects significant swaying of the adjustable-center-of-gravity photovoltaic floating platform 100. The supporting platform 30 then closes the installation space 33, isolating the photovoltaic system 40 within the installation space 33 from the outside world, protecting the photovoltaic system 40 from extreme loads and extending its service life. Simultaneously, the supporting platform 30 descends relative to the buoy 10, lowering the center of gravity of the adjustable-center-of-gravity photovoltaic floating platform 100 and improving its stability. When the inclination sensor 20 detects less swaying of the adjustable-center-of-gravity photovoltaic floating platform 100, the supporting platform 30 ascends relative to the buoy 10 and opens, connecting the photovoltaic system 40 to the outside world and enabling power generation.

[0062] The buoy 10 provides buoyancy for the photovoltaic floating platform 100 with an adjustable center of gravity, allowing it to float on the sea surface. A tilt sensor 20 is located on top of the buoy 10 and is used to detect the tilt of the buoy 10 in real time. When the buoy 10 on the sea surface is subjected to environmental loads such as wind, waves, and currents, these loads exert external forces on the buoy 10, causing it to tilt. This in turn causes the entire photovoltaic floating platform 100 to tilt, leading to instability. If the tilt angle is too large, the photovoltaic floating platform 100 is at risk of capsizing. The tilt sensor 20 is used to detect the tilt of the buoy 10 in real time. The larger the tilt angle, the greater the environmental loads the buoy 10 is experiencing. When the inclination sensor 20 detects that the inclination of the buoy 10 is greater than a preset value, the supporting platform 30 closes the installation space 33 to prevent seawater from flowing into the installation space 33 due to excessive environmental loads and corroding the photovoltaic system 40. Closing the installation space 33 can extend the service life of the photovoltaic system 40 in extreme environments. After closing the installation space 33, the supporting platform 30 descends along the axial direction of the buoy 10 to lower the overall center of gravity of the adjustable photovoltaic floating platform 100. This allows the portion of the structure of the adjustable photovoltaic floating platform 100 that floats on the sea surface to sink below the sea surface. This reduces the impact and influence of environmental loads on the adjustable photovoltaic floating platform 100 in extreme environments, further extending the service life of the adjustable photovoltaic floating platform 100. Furthermore, as the center of gravity of the adjustable photovoltaic floating platform 100 is lowered, its stability is increased. When the tilt sensor 20 detects that the tilt of the buoy 10 is below a preset value, indicating that the environment has returned to normal after the extreme environment, the supporting platform 30 rises along the axial direction of the buoy 10 to raise the center of gravity of the photovoltaic floating platform 100 with adjustable center of gravity, allowing the supporting platform 30 to float above the sea surface and obtain sufficient sunlight for the photovoltaic system 40 to generate electricity. After the supporting platform 30 floats above the sea surface, the installation space 33 opens, connecting the photovoltaic system 40 within the installation space 33 with the outside world, enabling the photovoltaic system 40 to generate electricity. The tilt sensor 20 dynamically adjusts the center of gravity of the photovoltaic floating platform 100 based on the measured tilt of the buoy 10, allowing the photovoltaic floating platform 100 to adjust its center of gravity according to changes in environmental loads, thereby extending the service life of the photovoltaic floating platform 100 with adjustable center of gravity in extreme environments and improving its stability.

[0063] When the environmental load is too large and causes the photovoltaic floating platform 100 with adjustable center of gravity to overturn as a whole, the tilt sensor 20 will detect that the photovoltaic floating platform 100 with adjustable center of gravity is in a flipped state and alarm, so that the staff can promptly maintain the flipped photovoltaic floating platform 100 with adjustable center of gravity to make it work normally.

[0064] Reference Figures 1 to 7In one embodiment of the present invention, the carrying platform 30 includes:

[0065] A supporting seat 31 is movably mounted on the outer peripheral surface of the buoy 10 , and a side of the supporting seat 31 facing the tilt sensor 20 is inwardly recessed to form a sinking platform 314 , and the photovoltaic system 40 is disposed on the surface of the sinking platform 314 ; and

[0066] a retractable top plate 32 , the retractable top plate 32 being retractably disposed on a side wall of the sunken platform 314 , and being used to close the sunken platform 314 to form the installation space 33 , or to open the installation space 33 to enable the photovoltaic system 40 to generate electricity;

[0067] The telescopic top plate 32 and the supporting base 31 are electrically connected to the tilt sensor 20 respectively.

[0068] In the technical solution of one embodiment of the present invention, the supporting seat 31 can be raised and lowered along the axial direction of the buoy 10. A sinking platform 314 is formed in the supporting seat 31, and the telescopic top plate 32 is telescopically arranged on the side wall of the supporting seat 31. When the telescopic top plate 32 extends above the sinking platform 314, the sinking platform 314 can be closed and enclosed with the sinking platform 314 to form an installation space 33. At this time, the installation space 33 is isolated from the outside world, and the photovoltaic system 40 located in the installation space 33 can prevent seawater from seeping into the installation space 33 and being corroded.

[0069] The retractable top plate 32 and the supporting base 31 are each electrically connected to the inclination sensor 20. When the inclination sensor 20 detects that the inclination angle of the buoy 10 is greater than a preset value, the retractable top plate 32 seals the sunken platform 314, isolating the installation space 33 from the outside world. Simultaneously, the supporting base 31 descends along the axial direction of the buoy 10 to lower the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity. When the inclination sensor 20 detects that the inclination angle of the buoy 10 is less than a preset value, the supporting base 31 ascends along the axial direction of the buoy 10 to raise the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity, allowing the supporting base 31 to float above the sea surface. The retractable top plate 32 then retracts to open the installation space 33, connecting it to the outside world, thereby enabling the photovoltaic system 40 to generate electricity. Based on the measured value of the buoy 10, the inclination sensor 20 sends a signal to the retractable roof 32 to open or close the installation space 33, preventing seawater from infiltrating the installation space 33 and corroding the photovoltaic system 40 due to excessive environmental loads. When the environmental load is excessive, the inclination sensor 20 lowers the height of the support base 31, thereby lowering the center of gravity of the adjustable photovoltaic floating platform 100, preventing instability and improving the stability of the adjustable photovoltaic floating platform 100.

[0070] Reference Figures 1 to 7 In one embodiment of the present invention, the supporting seat 31 includes:

[0071] a sleeve 311 , the sleeve 311 being raised and lowered on the outer surface of the buoy 10 , and the sleeve 311 being electrically connected to the tilt sensor 20 ;

[0072] a bottom plate 312 , the bottom plate 312 extending from the outside of the sleeve 311 in a direction away from the buoy 10 , the photovoltaic system 40 being disposed on a side of the bottom plate 312 facing the tilt sensor 20 ; and

[0073] The enclosing plate 313 is provided on a side of the bottom plate 312 away from the sleeve 311 and is enclosed with the bottom plate 312 and the sleeve 311 to form the sinking platform 314. The telescopic top plate 32 is telescopically provided on the enclosing plate 313;

[0074] When the sink 314 is closed, the telescopic top plate 32 abuts against the sleeve 311;

[0075] When the sunken platform 314 is opened, the telescopic top plate 32 retracts to the enclosure plate 313 .

[0076] In the technical solution of one embodiment of the present invention, the supporting seat 31 includes a sleeve 311, a bottom plate 312 and a surrounding plate 313. The photovoltaic system 40 is installed on the bottom plate 312, and the photovoltaic panels of the photovoltaic system 40 are arranged toward the top of the sinking platform 314 to obtain sufficient light. The bottom plate 312 can be raised and lowered along the axial direction of the buoy 10 with the sleeve 311. The surrounding plate 313 is arranged opposite to the sleeve 311. The retractable top plate 32 provided on the surrounding plate 313 can extend toward the sleeve 311 and abut against the outer wall of the sleeve 311 to close the sinking platform 314, or retract from the outer wall of the sleeve 311 to the surrounding plate 313 to open the sinking platform 314. The retractable setting of the retractable top plate 32 can form an installation space 33 separated from the outside world, thereby preventing seawater from seeping into the installation space 33 and extending the service life of the photovoltaic system 40 in the installation space 33.

[0077] Reference Figures 1 to 7 In one embodiment of the present invention, the photovoltaic floating platform 100 with adjustable center of gravity further comprises:

[0078] a guide rail 50 provided on the outer peripheral surface of the buoy 10 and extending along the axial direction of the buoy 10; and

[0079] a sliding member 60 , the sliding member 60 being disposed on the guide rail 50 and movable along the length direction of the guide rail 50 , the sliding member 60 being fixedly connected to the inner side of the sleeve 311 ; and

[0080] A driving member (not shown) is transmission-connected to the sliding member 60 , and is electrically connected to the tilt sensor 20 .

[0081] In the technical solution of one embodiment of the present invention, a guide rail 50 is further provided on the outer wall of the buoy 10. A sliding member 60 is disposed on the guide rail 50 and is movable along the length of the guide rail 50. The sliding member 60 is fixedly connected to the sleeve 311, thereby driving the support platform 30 to rise and fall along the axial direction of the buoy 10. The driving member can be a motor, or a device such as a cylinder, a hydraulic cylinder, or a telescopic rod 14, and the type of driving member is not limited herein. The driving member can drive the sliding member 60 to move along the length of the guide rail 50, thereby achieving the lifting and lowering of the support platform 30 along the axial direction of the buoy 10, thereby adjusting the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity and improving the stability of the photovoltaic floating platform 100 with an adjustable center of gravity.

[0082] Reference Figures 1 to 7 In one embodiment of the present invention, the buoy 10 includes:

[0083] A substrate 11, wherein the tilt sensor 20 is provided on the substrate 11;

[0084] a sealing plate 12 , the sealing plate 12 being located below the substrate 11 and arranged opposite to the substrate 11 ; and

[0085] The side panels 13 are connected to the base plate 11 and the sealing plate 12 at their top and bottom, respectively, to form a pressurized water compartment 15 . The carrying platform 30 is sleeved on the outside of the side panels 13 .

[0086] The sealing plate 12 is electrically connected to the tilt sensor 20 , and the sealing plate 12 can be opened or closed to open or close the pressure water chamber 15 .

[0087] In the technical solution of one embodiment of the present invention, a buoy 10 includes a base plate 11, a sealing plate 12, and side plates 13. A ballast tank 15 is formed within buoy 10. The sealing plate 12 can open the ballast tank 15 to allow it to draw in seawater, thereby increasing the overall weight of the adjustable-center-of-gravity photovoltaic floating platform 100, lowering its center of gravity, and improving its stability in extreme environments. When the extreme environment returns to normal and the environmental load decreases, the sealing plate 12 can open the ballast tank 15 and discharge the seawater, thereby reducing the overall weight of the adjustable-center-of-gravity photovoltaic floating platform 100 and raising its center of gravity above the sea surface, thereby obtaining a better angle of illumination for power generation by the photovoltaic system 40. The tilt sensor 20 determines the magnitude of the external environmental load by detecting the tilt of the buoy 10. When the tilt sensor 20 detects that the tilt angle is greater than a preset value, the sealing plate 12 opens and causes the ballast tank 15 to draw in seawater to lower the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity. After the center of gravity adjustment is completed, the sealing plate 12 closes the ballast tank 15 to maintain the adjusted center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity. When the tilt sensor 20 detects that the tilt angle is less than a preset value, the sealing plate 12 opens again and causes the ballast tank 15 to discharge seawater to raise the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity. After the center of gravity adjustment is completed, the sealing plate 12 closes the ballast tank 15 to maintain the adjusted center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity.

[0088] A water level monitor (not shown) may also be provided in the buoy 10 to monitor the water level in the ballast tank 15. When the ballast tank 15 is fully loaded, if the inclination sensor 20 still detects that the inclination of the buoy 10 is greater than a preset value, an alarm will be activated to prompt the staff to perform maintenance.

[0089] Reference Figures 1 to 7 In one embodiment of the present invention, the sealing plate 12 includes:

[0090] a first hinge plate 121 , which is disposed opposite to the base plate 11 and located at the bottom of the side plate 13 ; and

[0091] A second hinge plate 122 rotatably connected to the first hinge plate 121 ;

[0092] When the first hinge plate 121 and the second hinge plate 122 are in the same plane, the pressure tank 15 is closed;

[0093] When the first hinge plate 121 and the second hinge plate 122 are not in the same plane, the pressure chamber 15 is opened.

[0094] In the technical solution of one embodiment of the present invention, the sealing plate 12 includes a first hinge plate 121 and a second hinge plate 122, and the second hinge plate 122 can rotate around the first hinge plate 121. When the first hinge plate 121 and the second hinge plate 122 are in the same plane, the ballast tank 15 is in an open state, and the ballast tank 15 can suck in or discharge seawater to adjust the center of gravity. When the first hinge plate 121 and the second hinge plate 122 are not in the same plane, the ballast tank 15 is in a closed state. At this time, the weight of the buoy 10 remains unchanged to maintain the adjusted center of gravity. The design of the sealing plate 12 improves the stability of the photovoltaic floating platform 100 with an adjustable center of gravity.

[0095] A sealing member (not shown) is provided on the rotating outer edge of the second hinge plate 122 to seal the second hinge plate 122 and the side plate 13. The material of the sealing member can be rubber, silicone, or other corrosion-resistant materials, and the material of the sealing member is not limited here.

[0096] Reference Figures 1 to 7 In one embodiment of the present invention, the first hinge plate 121 can move along the axial direction of the float 10 to approach or move away from the base plate 11.

[0097] In the technical solution of one embodiment of the present invention, the first hinge plate 121 can move along the axial direction of the buoy 10 to move closer to or away from the base plate 11, thereby adjusting the volume of the ballast tank 15. When the ballast tank 15 needs to absorb water to lower the center of gravity of the photovoltaic floating platform 100 with adjustable center of gravity, the first hinge plate 121 moves away from the base plate 11 to increase the volume of the ballast tank 15. At the same time, the second hinge plate 122 opens, allowing seawater to flow into the ballast tank 15 through the second hinge plate 122. When the center of gravity is adjusted, the second hinge plate 122 closes to maintain the adjusted center of gravity of the photovoltaic floating platform 100 with adjustable center of gravity. When the ballast tank 15 needs to be drained to raise the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity, the first hinge plate 121 moves toward the base plate 11 to reduce the volume of the ballast tank 15. Simultaneously, the second hinge plate 122 opens, and the seawater within the ballast tank 15 is squeezed out of the ballast tank 15 by the first hinge plate 121 due to the reduced volume of the ballast tank 15. Once the center of gravity is adjusted, the second hinge plate 122 closes to maintain the adjusted center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity. The movable arrangement of the first hinge plate 121 enables the ballast tank 15 to absorb and drain water, thereby adjusting the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity and improving its stability in extreme environments.

[0098] Reference Figures 1 to 7In one embodiment of the present invention, the pontoon 10 further includes a telescopic rod 14, which is telescopically arranged in the pressure tank 15. The telescopic rod 14 is arranged along the axial direction of the pontoon 10, and one end of the telescopic rod 14 is fixed to the bottom of the base plate 11, and the other end of the telescopic rod 14 is fixed to the top of the first hinge plate 121. The telescopic rod 14 is electrically connected to the inclination sensor 20.

[0099] In the technical solution of one embodiment of the present invention, one end of the telescopic rod 14 is connected to the base plate 11, and the other end is connected to the first hinge plate 121. When the tilt sensor 20 detects that the tilt angle of the buoy 10 is higher than a preset value, the telescopic rod 14 extends, and the first hinge plate 121 moves away from the base plate 11, thereby increasing the volume of the ballast tank 15 to absorb more seawater, lowering the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity, and improving the stability of the photovoltaic floating platform 100 with an adjustable center of gravity in extreme environments. When the tilt sensor 20 detects that the tilt angle of the buoy 10 is lower than a preset value, the telescopic rod 14 shortens, and the first hinge plate 121 moves toward the base plate 11, thereby reducing the volume of the ballast tank 15 to discharge the seawater inside the ballast tank 15, and raising the center of gravity of the photovoltaic floating platform 100 with an adjustable center of gravity, so that the photovoltaic system 40 on the supporting platform 30 can obtain a better angle of illumination.

[0100] The telescopic rod 14 can be telescopically arranged and can be driven to extend and retract by a cylinder, a hydraulic cylinder or a motor, etc. The driving method of the telescopic rod is not limited here.

[0101] Reference Figures 1 to 7 In one embodiment of the present invention, the photovoltaic floating platform 100 with adjustable center of gravity further comprises:

[0102] An anchor chain 70, one end of which is fixed to the carrying platform 30; and

[0103] An anchor head (not shown) is fixed to the other end of the anchor chain 70 and is used to be inserted into the seabed to fix the photovoltaic floating platform 100 with adjustable center of gravity.

[0104] In the technical solution of one embodiment of the present invention, the photovoltaic floating platform 100 with an adjustable center of gravity further includes an anchor head and an anchor chain 70, wherein one end of the anchor chain 70 is fixed to the surface of the photovoltaic floating platform 100 with an adjustable center of gravity. It can be fixed to the support platform 30 or the buoy 10, and the fixed position of the anchor chain 70 is not limited herein. The other end of the anchor chain 70 is fixed to the anchor head, which sinks into the sea surface and anchors to the seabed, thereby defining the installation area of the photovoltaic floating platform 100 with an adjustable center of gravity and preventing the photovoltaic floating platform 100 from drifting away from the installation area due to environmental loads, making it impossible to recover. The provision of the anchor head and anchor chain 70 extends the service life and reusability of the photovoltaic floating platform 100 with an adjustable center of gravity.

[0105] Reference Figures 1 to 7 In one embodiment of the present invention, the photovoltaic floating platform 100 with adjustable center of gravity further includes a light sensor (not shown), which is electrically connected to the carrying platform 30 to open or close the installation space 33 according to the ambient light intensity.

[0106] In the technical solution of one embodiment of the present invention, the photovoltaic floating platform 100 with an adjustable center of gravity also includes a light sensor. The photovoltaic system 40 can only generate electricity stably during the day when the light intensity is greater than a certain value. The light sensor is used to detect the external light intensity. When the light sensor detects that the light intensity is greater than a preset value, the carrier platform 30 opens the installation space 33, allowing the photovoltaic system 40 in the installation space 33 to generate electricity. When the light sensor detects that the light intensity is lower than the preset value, which is usually at night or on cloudy or rainy days, the photovoltaic system 40 can no longer generate electricity stably. The carrier platform 30 closes the installation space 33 to prevent seawater from infiltrating the installation space 33 and corroding the photovoltaic system 40, thereby extending the service life of the photovoltaic floating platform 100 with an adjustable center of gravity.
