In an 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 is rotatable around the first hinge plate 121. When the first hinge plate 121 and the second hinge plate 122 are in the same plane, the pressurized water compartment 15 is in an opened state, and the pressurized water compartment 15 can suck or discharge seawater to adjust the center of gravity. When first hinge plate 121 and second hinge plate 122 are not in the same plane, pressurized water compartment 15 is in a closed position, where the weight of buoy 10 remains unchanged to maintain the adjusted center of gravity. The design of the sealing plate 12 improves the stability of the structure of the photovoltaic floating platform 100 with an adjustable center of gravity.
A seal (not shown) is provided on the outer edge of the second hinge plate 122 for sealing the second hinge plate 122 from the side plate 13. The material of the sealing member may be rubber, silica gel, or other corrosion-resistant materials, and the material of the sealing member is not limited herein.
Referring to fig. 1-7, in one embodiment of the invention, the first hinge plate 121 is movable in the axial direction of the buoy 10 to move toward or away from the base plate 11.
In one embodiment of the present invention, first hinge plate 121 is movable in the axial direction of buoy 10 to move closer to or further from base plate 11 to adjust the volume of pressurized water compartment 15. When the pressurized water tank 15 needs to absorb water to lower the gravity center of the photovoltaic floating platform 100 with the adjustable gravity center, the first hinge plate 121 moves in a direction away from the base plate 11 to increase the volume of the pressurized water tank 15, meanwhile, the second hinge plate 122 is opened, seawater flows into the pressurized water tank 15 through the second hinge plate 122, and after the gravity center adjustment is completed, the second hinge plate 122 is closed to maintain the gravity center of the photovoltaic floating platform 100 with the adjustable gravity center. When the pressurized water tank 15 needs to drain water to raise the center of gravity of the photovoltaic floating platform 100 with the adjustable center of gravity, the first hinge plate 121 moves towards the direction of the base plate 11 to reduce the volume of the pressurized water tank 15, meanwhile, the second hinge plate 122 is opened, the seawater in the pressurized water tank 15 is extruded out of the pressurized water tank 15 by the first hinge plate 121 due to the reduction of the volume of the pressurized water tank 15, and after the center of gravity adjustment is completed, the second hinge plate 122 is closed to maintain the center of gravity of the photovoltaic floating platform 100 with the adjustable center of gravity. The movable arrangement of the first hinge plate 121 realizes the functions of water absorption and water drainage of the pressurized water cabin 15, thereby realizing the adjustment of the gravity center of the gravity-adjustable photovoltaic floating platform 100 and improving the stability of the gravity-adjustable photovoltaic floating platform 100 in extreme environments.
Referring to fig. 1 to 7, in an embodiment of the present invention, the buoy 10 further includes a telescopic rod 14, the telescopic rod 14 is telescopically disposed in the pressurized water tank 15, the telescopic rod 14 is disposed along an axial direction of the buoy 10, one end of the telescopic rod 14 is fixed to the bottom of the base plate 11, the other end of the telescopic rod 14 is fixed to the top of the first hinge plate 121, and the telescopic rod 14 is electrically connected to the inclination sensor 20.
In an 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 tilt sensor 20 detects that the tilt of buoy 10 is above a predetermined level, telescoping rod 14 will extend and first hinge plate 121 will move away from base plate 11, thereby increasing the volume of pressurized water compartment 15 to draw in more seawater and lowering the center of gravity of center-adjustable photovoltaic floating platform 100 and increasing the stability of center-adjustable photovoltaic floating platform 100 in extreme environments. When the inclination sensor 20 detects that the inclination of the buoy 10 is lower than a preset value, the telescopic rod 14 is shortened, and the first hinge plate 121 moves towards the direction close to the base plate 11, so that the volume of the pressurized water tank 15 is reduced to discharge the seawater in the pressurized water tank 15 to the outside, and the gravity center of the gravity-center-adjustable photovoltaic floating platform 100 is raised, so that the photovoltaic system 40 in the bearing platform 30 obtains a better illumination angle.
The telescopic rod 14 is telescopically arranged, and the telescopic rod 14 can be driven to stretch and retract by means of a cylinder, a hydraulic cylinder, a motor or the like, and the driving mode of the telescopic rod is not limited.
Referring to fig. 1 to 7, in an embodiment of the present invention, the gravity center adjustable photovoltaic floating platform 100 further includes:
an anchor chain 70, wherein one end of the anchor chain 70 is fixed on the bearing platform 30; and
an anchor head (not shown) is secured to the other end of the anchor chain 70 for insertion into the seabed to secure the center of gravity adjustable photovoltaic floating platform 100.
In an embodiment of the present invention, the photovoltaic floating platform 100 with 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 adjustable center of gravity, and may be fixed to the load-bearing platform 30 or the buoy 10, and the fixing position of the anchor chain 70 is not limited. The other end of the anchor chain 70 is fixed on an anchor head, the anchor head is sunk into the sea surface and anchored on the sea bottom, so that the installation area of the photovoltaic floating platform 100 with the adjustable gravity center can be limited, and the situation that the photovoltaic floating platform 100 with the adjustable gravity center floats away from the installation area under the action of environmental load and cannot be retrieved is avoided. The provision of anchor heads and chains 70 extends the useful life and multiplexing performance of center-of-gravity adjustable photovoltaic floating platform 100.
Referring to fig. 1 to 7, in an embodiment of the present invention, the center-of-gravity adjustable photovoltaic floating platform 100 further includes an illumination sensor (not shown) electrically connected to the carrying platform 30 to open or close the installation space 33 according to the ambient illumination intensity.
In an embodiment of the present invention, the photovoltaic floating platform 100 with an adjustable center of gravity further includes an illumination sensor. The photovoltaic system 40 can stably generate power only when the illumination intensity is greater than a certain value during daytime. The illumination sensor is used for detecting the external illumination intensity, and when the illumination intensity detected by the illumination sensor is greater than a preset value, the bearing platform 30 opens the installation space 33, so that the photovoltaic system 40 in the installation space 33 generates power. When the illumination sensor detects that the illumination intensity is lower than the preset value, the photovoltaic system 40 cannot stably generate electricity in the environment such as the night, cloudy day, rainy day, etc., the bearing platform 30 closes the installation space 33 to prevent seawater from penetrating into the installation space 33 and corroding the photovoltaic system 40, thereby prolonging the service life of the photovoltaic floating platform 100 with adjustable center of gravity.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
