[0002] Photovoltaic is the abbreviation of solar photovoltaic power generation system. It is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to convert solar radiation energy into electrical energy. With the development of society, solar energy as a new type of clean energy has gradually attracted people's attention and achieved good development results. Compared with ground photovoltaic power stations, water power stations avoid land restrictions and also play a certain protective role in the ecological environment of water, such as reducing water evaporation and inhibiting the reproduction of algae. In addition, they can be combined with aquaculture to truly realize the comprehensive utilization of resources. Among them, floating power stations on the water are the most important application form of water power stations, which were developed earlier abroad. There are two modes of water photovoltaic brackets: pile foundation fixed and water surface floating, but offshore photovoltaic brackets can only be floating. Basically, they are fixed and floated on the water by floating tubes or buoys combined with steel structure bases and brackets.

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0029] A photovoltaic support for sea surface in this embodiment relates to the technical field of photovoltaic support, and the floating frame 100 of the photovoltaic support is streamlined so that the floating support is less susceptible to impact and fluctuation. An elastic member 320 is provided between the floating ball 200 and the floating frame 100, which can effectively buffer and dampen the movement of the floating ball 200, prevent the solar panel 220 from being shaken violently, enhance the overall ability of the photovoltaic support to resist wind and waves, and protect the photovoltaic support and the solar panel 220 from damage.

[0030] See also Figures 1 to 5In this embodiment, a photovoltaic support for the sea surface includes: a floating frame 100, a floating ball 200 and a connecting assembly 300. The floating frame 100 can be set directly facing the surge, so that the effective area is smaller and the overall fluctuation of the floating frame is smaller. The floating ball 200 can make the solar panel 220 float on the sea surface in the form of a small module, which is convenient for the staff to install, maintain or replace. The connecting assembly 300 can make the floating ball 200 maintain an elastic connection with the floating frame 100, and buffer and reduce vibration of the floating ball 200.

[0031] The floating frame 100 includes a frame body 110 and a tail plate 120. The frame body 110 is streamlined. The streamlined shape can effectively reduce the vortex effect of surges or avoid the formation of vortices, thereby greatly reducing the resistance of waves to the floating frame 100, thereby avoiding the floating frame 100 from violent ups and downs under the action of resistance, and forming a relatively stable installation area inside the floating frame 100.

[0032] The buoy 200 includes a sphere 210 floating on the sea surface and a solar panel 220. The solar panel 220 is arranged on the top of the sphere 210 and is fixedly connected to the sphere 210. The solar panel 220 is divided into smaller modules. Each solar panel 220 can cooperate with a buoy 200, thereby achieving the effect of reducing the area of ​​the solar panel 220. When a surge acts on the solar panel 220, the smaller the area, the smaller the force, and the smaller the relative shaking and fluctuation. The solar panel 220 is connected to the top of the sphere 210, so that it is not easily impacted and damaged by waves, and can receive solar radiation to the maximum extent.

[0033] The connection assembly 300 includes a plurality of connectors 310 and an elastic member 320. The connectors 310 are arranged across the frame 110. The two ends of the connectors 310 are respectively fixedly connected to the two sides of the frame 110. The connectors 310 are located in the installation area. The two ends of the elastic member 320 are respectively connected to the connector 310 and the bottom of the sphere 210. The elastic member 320 can pull the sphere 210 so that the sphere 210 is always subjected to downward traction, keeping the sphere 210 relatively stable, preventing the solar panel 220 from being violently shaken, enhancing the overall ability of the photovoltaic bracket to resist wind and waves, and protecting the photovoltaic bracket and the solar panel 220 from damage.

[0034] In some embodiments, see Figure 4 and Figure 5The sphere 210 is hollow inside, and part of the sphere 210 is filled with a weighted liquid. A filling hole and a hole plug are provided on the sphere 210. The filling amount of the weighted liquid can be adjusted as needed, and the weight and buoyancy of the sphere 210 can be adjusted to control the floating depth of the sphere 210 in the water. By reasonably adjusting the amount of the weighted liquid, the system can maintain a suitable floating depth under different conditions to adapt to different sea conditions and lighting conditions. In addition, filling the sphere 210 with weighted liquid can increase the weight of the system, thereby increasing the stability of the system on the water surface. Moreover, the mass of the weighted liquid can increase the inertia of the sphere 210, making it more resistant to the impact of waves, thereby reducing the influence of external forces on the solar panel 220 and improving its ability to resist wind and waves.

[0035] As a further implementation, see Figure 4 The sphere 210 is gradually expanded from bottom to top and is relatively smooth. The smooth surface design of the sphere 210 helps to improve the fluid dynamics, reduce the resistance and pressure when the waves hit, and thus reduce the risk of damage to the bracket. This design helps the bracket to better adapt to the marine environment and improves the durability and reliability of the system. The gradually expanding sphere 210 design can increase the bottom width of the sphere 210, thereby increasing the stability of the entire buoy 200 system. The design with a larger bottom width helps to reduce the roll and shaking of the bracket under the action of waves, thereby improving the stability of the bracket.

[0036] In the specific implementation process, the solar panel 220 is installed on the installation plane 211 on the top of the sphere 210, and it is ensured that the plane is vertically aligned with the central axis of the sphere 210. The solar panel 220 is installed on the installation plane 211 on the top of the sphere 210 to ensure that the panel can receive sunlight to the maximum extent. Because the sun's trajectory is usually oblique from the zenith to the horizon, and the central axis of the sphere 210 is perpendicular to the horizon, the installation plane 211 can be better perpendicular to the sunlight, so that the panel can receive the maximum light intensity, thereby improving the power generation efficiency.

[0037] In addition, the solar panel 220 is installed on the plane of the top of the sphere 210, and the surface is smoother, which reduces the resistance to wind, reduces the impact of wind on the entire photovoltaic system, and further improves the stability and durability of the system.

[0038] In some embodiments, please refer to Figure 4The solar panel 220 is a regular hexagon, and the mounting plane 211 is a circle. When the regular hexagonal solar panel 220 is cut and manufactured, the material of the solar panel 220 can be used to the maximum extent, avoiding the appearance of fertilizers and improving the utilization rate of materials. Since the circumscribed circle of the regular hexagon is the same as the inner diameter of the mounting plane 211, each side of the solar panel 220 can make full use of the space of the mounting plane 211, thereby improving the light energy collection efficiency of the photovoltaic system. In addition, the solar panel 220 is completely embedded in the mounting plane 211, and there is no part of the solar panel 220 protruding from the mounting plane 211, which can reduce the roll and swing of the system under the impact of waves, reduce the risk of damage, and improve the stability of the system.

[0039] In the specific implementation process, the elastic member 320 is designed as an elastic rope or a spring, and is relatively stretched. The relatively stretched setting of the elastic member 320 can play a buffering role under the impact of waves. When the waves impact the bracket, the elastic rope or spring can stretch or compress, absorb part of the impact energy, slow down the impact force on the sphere 210, reduce the risk of damage to the system, and protect the bracket and the solar panel 220. The setting of the elastic member 320 can reduce the direct impact of the stress point of the system, reduce the wear of the bracket and the connecting member 310, and thus extend the service life of the entire system.

[0040] In some embodiments, see Figure 3 , both ends of the connector 310 are detachably connected to the frame 110, and the connector 310 is a rigid part. Both ends of the connector 310 are connected to the frame 110 by bolts. The detachable design of the connector 310 makes the installation and maintenance of the bracket more convenient. The connector 310 can be quickly disassembled when necessary to adjust, maintain or replace parts of the system without large-scale dismantling and reinstallation, saving time and labor costs. The connector is a rigid part, which can provide good support and fixing effects and enhance the stability of the entire system. The rigid connector 310 can effectively transmit force and withstand pressure, ensure the stability of the elastic member 320 and the buoy 200 in the offshore environment, and reduce the risk of damage.

[0041] In some embodiments, see Figure 3 and Figure 4 A detachable connecting unit is provided between the elastic member 320 and the connecting member 310. The connecting unit may be a buckle, a cable tie or a connecting rope, etc. The floating balls 200 may be disassembled and assembled as needed to change the spacing between the floating balls 200.

[0042] In addition, during transportation, the float 200 can be separated from the bracket, reducing the transportation volume and weight; during installation, the bracket can be installed first, and then the float 200 and the bracket can be connected through a detachable connection unit, reducing the complexity and risk of installation.

[0043] In some embodiments, the frame 110 is relatively hollow, and the frame 110 itself can float on the sea surface and protrude from the sea surface to shield the internal buoy 200 from wind and waves. An anchor cable is arranged below the frame 110, and an anchor cable is arranged below the frame 110. The two ends of the anchor cable are respectively connected to the frame 110 and the seabed. The anchor cable can fix the photovoltaic bracket in a certain sea area to prevent the photovoltaic bracket from drifting.

[0044] Workflow: First, use the anchor cable to fix the frame 110 in the predetermined sea area. The surge can act on the tail plate 120, which can guide the frame 110 to face the surge. The streamlined frame 110 can reduce the action area between the frame 110 and the waves, making the overall fluctuation of the floating frame smaller, and forming a relatively stable installation area in the frame 110. The buoy 200 is installed on the frame 110 through the elastic member 320. The elastic member 320 can pull the sphere 210 so that the sphere 210 is always subjected to downward traction, keeping the sphere 210 relatively stable, reducing the impact of the surge on the sphere 210, preventing the solar panel 220 from being violently shaken, enhancing the overall ability of the photovoltaic bracket to resist wind and waves, and protecting the photovoltaic bracket and the solar panel 220 from damage.

[0045] The above description is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be covered by the present invention.
