However, the complex and ever-changing marine environment, often facing challenges such as strong winds and waves, corrosion from high-salt spray, and the attachment of marine organisms, poses a serious challenge to the stable operation of offshore PV power generation systems. While breakwaters can provide some protection, they are costly to construct and occupy a large amount of space, and wave-damping blocks are sometimes ineffective. Although air curtain wave-damping technology has been applied in ports and other fields, it has not yet formed an energy loop with PV power generation. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "joining" should be interpreted broadly, for example, they can refer to fixed connections, detachable connections, or integral connections; those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" can explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0028] This application provides an embodiment of a nearshore photovoltaic power generation protection system based on air curtain wave attenuation. An air curtain wave attenuation device is cleverly arranged around the photovoltaic panel, fully leveraging the synergistic effect of the two. The photovoltaic panel, based on the photovoltaic effect at the semiconductor interface, can efficiently convert light energy directly into electrical energy, which is then stored in solar cells. These solar cells continuously supply the air curtain wave attenuation device with the power required for its operation, thus establishing a good model for the internal recycling of renewable energy.

[0029] Reference Figures 1 to 6 The nearshore photovoltaic power generation protection system based on air curtain wave facilitation in this application embodiment includes a photovoltaic power generation energy storage device 1 and eight air curtain wave facilitation devices 2 disposed around the periphery of the photovoltaic power generation energy storage device 1. It should be noted that the number of air curtain wave facilitation devices 2 can also be seven or nine, etc., depending on the actual working conditions, and is not limited here.

[0030] The photovoltaic power generation and energy storage device 1 includes a photovoltaic panel 11 mounted on the mounting structure 3 and solar cells 12 electrically connected to the photovoltaic panel 11. The photovoltaic panel 11 uses the photovoltaic effect to convert solar energy into electrical energy, and the solar cells 12 are used to store the generated electrical energy and provide a continuous energy supply for the air curtain wave-damping device 2. The mounting structure 3 is a seawall or water surface structure.

[0031] Reference Figures 1 to 3 The top surface of the mounting structure 3 is circular, and there are sixteen photovoltaic panels 11 arranged in a 4×4 rectangular array. The photovoltaic panels 11 in the first row and the first and fourth columns of the fourth row are all quarter-circular panels. There are sixteen solar cells 12, which are respectively installed under the corresponding photovoltaic panels 11.

[0032] Reference Figures 4 to 6 The air curtain wave-damping device 2 includes an air compressor 21, an exhaust pipe 22, and fifteen counterweights 23. Similarly, the number of counterweights 23 can be determined according to the actual working conditions, and is not limited here.

[0033] Air compressor 21 is mounted on mounting structure 3 and located outside photovoltaic power generation and energy storage device 1. Air compressor 21 is electrically connected to solar cell 12, which provides power to air compressor 21. Exhaust pipe 22 is laid in the underwater area outside solar cell 12, with its inlet end connected to air compressor 21. The laying direction of exhaust pipe 22 is determined according to the direction of wave arrival and seabed topography to ensure that it can cope with wave impacts from different directions in all directions. Specifically, in areas where waves often impact at an oblique angle, exhaust pipe 22 can be placed at a slight angle to make the angle between the formed air curtain and the wave more reasonable, more efficiently changing the wave propagation path and reducing energy, while avoiding the exhaust pipe's own stability and impact on the photovoltaic structure foundation due to unreasonable stress, thus ensuring the structural safety of the entire near-shore photovoltaic power generation system.

[0034] The exhaust pipe 22 can be made of high-strength, corrosion-resistant materials, such as high-quality stainless steel or special engineering plastics. These materials can maintain good structural integrity in harsh marine environments where the pipe is immersed in seawater for a long time and is subjected to water flow impact and pressure changes. They are not prone to damage, corrosion and perforation, ensuring the stable formation of the air curtain and thus providing reliable protection for the photovoltaic power generation and energy storage device 1.

[0035] The exhaust pipe 22 is provided with multiple exhaust holes 24. The exhaust holes 24 are used to release gas to form an air curtain to reduce the impact of waves on the photovoltaic panel 11. In some embodiments, the exhaust holes 24 are equidistantly arranged along the axial direction of the exhaust pipe 22, and each exhaust hole 24 is located between two adjacent counterweights 23. It should be noted that the layout and number of exhaust holes 24 are designed according to actual needs to ensure the continuity and uniformity of the air curtain, and are not limited here.

[0036] Each vent 24 is positioned between two adjacent counterweights 23 with appropriate spacing. This allows the gas discharged from the vent 24 to form an air curtain evenly and orderly, maximizing the wave-damping effect. When waves surge towards the area where the photovoltaic panel is located, the air curtain formed by the gas released through the vent vents of the vent pipe interacts with the waves, altering the original water flow structure and energy transfer path, effectively reducing the wave height and energy contained within, and significantly reducing the impact of the waves on the photovoltaic panel, thus achieving comprehensive and efficient protection for the photovoltaic power generation device.

[0037] To ensure the exhaust pipe 22 remains fixed underwater, fifteen counterweights 23 are installed on the exhaust pipe 22. The fifteen counterweights 23 are equidistantly arranged along the axial direction of the exhaust pipe 22 to ensure that the exhaust pipe will not be displaced by water flow or waves.

[0038] The counterweight 23 is usually made of high-density, stable and corrosion-resistant materials, such as cast iron or concrete encasing a metal frame. Its shape can be designed in various styles such as block or ring according to the shape of the exhaust pipe 22 and the installation requirements, so as to better fit the exhaust pipe 22, achieve a stable connection, and ensure that the exhaust pipe 22 will not be easily moved by the waves on the seabed, thereby stably supporting the entire air curtain wave-damping device 2 and indirectly protecting the photovoltaic power generation and energy storage device 1 from the impact of waves.

[0039] Based on the length and diameter of the exhaust pipe 22, as well as the wave intensity of the sea area, the distribution spacing and quantity of the counterweights should be scientifically planned. In areas with high wave impact, the counterweights should be appropriately denser to ensure that all parts of the exhaust pipe are subjected to uniform and balanced forces, maintain a stable structural state, and prevent problems such as deformation or displacement of the exhaust pipe due to excessive local forces.

[0040] The exhaust pipe 22 and the counterweight 23 are connected to the support and foundation structure of the photovoltaic panel 11 via flexible or buffered connectors. For example, the support and foundation structure of the photovoltaic panel 11 are connected via specially designed rubber connectors or retractable metal structures. In this way, even if the air curtain wave-damping device 2 is subjected to a large external impact under wave action, the transmission of impact force to the photovoltaic panel 11 can be reduced through these flexible or buffered connection structures, avoiding damage to the photovoltaic structure that may be caused by rigid connections, and ensuring the stability and durability of the entire nearshore photovoltaic power generation and energy storage device 1.

[0041] The usage process of this application embodiment is as follows:

[0042] The first step is to install the photovoltaic panels 11 on the seawall or water surface structure to ensure that they can absorb solar energy to the maximum extent.

[0043] The second step is to connect the photovoltaic panel 11 to the solar cell 12 so as to store the converted electrical energy.

[0044] The third step is to deploy an air curtain wave-damping device 2 around the photovoltaic panel 11, including laying an exhaust pipe 22 along the outer side of the photovoltaic panel 11 in the underwater area, and evenly arranging counterweights 23 on the exhaust pipe 22 to fix its position.

[0045] Step 4: Activate the air curtain wave-damping device 2. Use the electrical energy stored in the solar cell 12 to drive the exhaust port 24 to release gas and form an air curtain. Adjust the layout and exhaust volume of the exhaust port 24 according to the direction and intensity of the waves to achieve the best wave-damping effect.

[0046] Fifth, regularly monitor the operating status of the device and adjust the working mode of the photovoltaic panel 11 and the wave-damping device according to environmental changes to ensure the continuous and stable operation of the device, thereby effectively protecting the photovoltaic power generation device from wave impact and realizing the efficient utilization of green energy.

[0047] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
