Description

Technical Field

[0001] This invention relates to the field of marine photovoltaics, and particularly to a floating array of buoys resistant to wind and waves. Background Technology

[0002] Solar energy is a clean energy source. Using photovoltaic (PV) power plants to directly convert solar energy into electricity is a highly efficient way to utilize solar energy. Floating PV refers to building PV power plants on idle water surfaces. Floating PV power plants have many advantages, such as not occupying land resources, reducing water evaporation, and avoiding algae growth, and have broad development prospects.

[0003] One type of floating photovoltaic (PV) power station uses a floating array of solar panels. Currently, these PV power stations are mostly built on inland waters such as lakes and rivers. However, the complex marine environment, with its frequent large waves, causes significant surface fluctuations. Even in nearshore waters, the floating hulls of the PV array are constantly impacted by waves, affecting the overall stability of the array. Currently, the available inland water surfaces suitable for PV power station construction are gradually decreasing. Utilizing the vast open seas, both nearshore and offshore, to build PV power stations, providing clean energy, reducing carbon emissions, and contributing to carbon peaking and carbon balance, is a crucial future development direction in this field. Therefore, there is an urgent need for a floating array capable of withstanding strong winds and waves. Summary of the Invention

[0008] As described above, the floating array of buoys includes outwardly extending wing plates on both sides of the buoyancy device.

[0009] As described above, in the floating array of floats, the wing plates are inclinedly disposed on the buoyancy device, making it more difficult for the buoyancy device to enter the water and easier to float from the water.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the following detailed description, reference can be made to the accompanying drawings, which form part of this application and illustrate specific embodiments of the present application. In the drawings, similar reference numerals describe substantially similar components in different figures. Specific embodiments of the present application are described in sufficient detail below to enable those skilled in the art to implement the technical solutions of the present application. It should be understood that other embodiments may also be utilized, or structural, logical, or electrical changes may be made to the embodiments of the present application.

[0021] This application discloses a novel wind and wave resistant floating array that can reduce the impact of wind and waves on the floating array, prevent damage to the floating array, make the structure of the floating array more stable, and better adapt to the harsh natural environment at sea.

[0022] The technical solution of this application will be further illustrated below through specific implementation methods. Those skilled in the art should understand that the following description is merely for the convenience of understanding the technical solution of this application and should not be used to limit the scope of protection of this application.

[0023] Figures 1A-1C This is a schematic diagram of a wave-resistant floating array according to an embodiment of this application; wherein, Figure 1A This is a top view of the floating body array. Figure 1B and Figure 1C This is a side view of the floating body array.

[0024] As shown in the figure, the wave-resistant floating array (hereinafter referred to as "wave-resistant floating array") 100 includes: multiple floats 110, anchoring devices 120, and multiple buoyancy devices 130. The multiple floats 110 are interconnected to form the floating array 10, which can be used to support solar panels to form a photovoltaic power station, or to support cables or other electrical equipment, or auxiliary facilities such as fences. The anchoring devices 120 can be used to anchor the floating array 10 and also allow the floating array 10 to change position with the waves. In some embodiments, the anchoring devices 120 can be arranged around the perimeter of the floating array. When the floating array changes position with the waves, at least one anchoring device on one side of the floating array 10 is stressed, allowing the floating array to change position with the waves. In some embodiments, the anchoring devices can be multiple anchor blocks 121 disposed on the seabed.

[0025] Multiple buoyancy devices 130 are positioned between the anchoring device 120 and the floating array 10 and float on the water surface. The buoyancy of these devices can buffer the impact of wind and waves. When the floating array 10 changes position due to wind and waves, one or more of the buoyancy devices may partially or completely submerge underwater, using buoyancy to buffer the impact of wind and waves on the floating array and alleviate some of the impact force. When the submerged buoyancy devices 130 float back to the surface, the floating array 10 can be driven back to its original position by the re-floating buoyancy devices 130, thus preventing excessive displacement of the floating array and allowing it to automatically reset, buffering the impact of wind, waves, and water level changes on the floating array. In some embodiments, the buoyancy device can be a float, a buoy box, a float, etc. In some embodiments, examples of the buoyancy device can also be metal boxes, containers, cargo containers, or scrap containers, ships, foam buoys, buoy barrels, floating bridge modules, floating dock units, etc.

[0026] refer to Figure 1B and Figure 1C , Figure 1B The floating body array moves horizontally with the wind and waves (solid line represents the state before displacement, dashed line represents the state after displacement), and the buoyancy device is completely or partially submerged underwater. When the wind and waves subside, the buoyancy device will float back to the surface of the water, and at the same time drive the floating body array to reset. Figure 1C The floating body array moves vertically with the wind and waves (solid line represents the state before displacement, dashed line represents the state after displacement), with all or part of the buoyancy device submerged underwater. After the wind and waves subside, the buoyancy device floats back to the surface, simultaneously causing the floating body array to reset. Compared to traditional floating body arrays, the floating body array of this application can mitigate the impact of wind and waves, prevent excessive displacement, automatically reset the array, and has a more stable structure, capable of withstanding higher levels of wind and waves, thus adapting to harsher marine environments.

[0027] In some embodiments, the anchoring device 120 and the float array 10 may include one or more anchor lines 101, the connection point of the anchor line 101 and the anchoring device 120 being located underwater, and the buoyancy device 130 may be disposed on the anchor line. In some embodiments, the anchor line 101 may also be part of the anchoring device 120. In some embodiments, one anchor line may include one or more buoyancy devices. According to a preferred embodiment of this application, one anchor line may include three buoyancy devices. In some embodiments, one anchor line may also have other numbers of buoyancy devices, such as two, four or more.

[0028] In some embodiments, the buoyancy device 130 is disposed on the anchor line 101 near the float array, which can facilitate buffering the impact of wind and waves on the float array and also protect the float array from water ingress at its edges. In some embodiments, multiple buoyancy devices on the same anchor line can be arranged at unequal intervals, with the spacing between the buoyancy devices 130 decreasing as they approach the float array, thereby gradually increasing the resistance of the buoyancy device and thus gradually increasing the resistance to buffering the impact of wind and waves. In some embodiments, the multiple buoyancy devices on the same anchor line can have different volumes, with the buoyancy device closer to the float array having a larger volume, thereby gradually increasing the resistance of the buoyancy device and thus gradually increasing the resistance to buffering the impact of wind and waves.

[0029] This application also proposes other solutions for buffering the impact of wind and waves, which will be further described below.

[0030] Figure 2A and Figure 2B This is a schematic diagram of a buoyancy device according to an embodiment of this application.

[0031] As shown in the figure, the buoyancy device 200 includes a main body 210 and wing plates 220. The wing plates 220 can be disposed on the main body 210 and extend to both sides of the main body 210, which can further increase the buoyancy of the buoyancy device and enhance its ability to buffer the impact of wind and waves. In some embodiments, the main body 210 and the wing plates 220 can be integrally formed, improving the overall strength and stability of the buoyancy device.

[0032] In some embodiments, the wing plate 220 is inclinedly disposed on the main body 210, which makes it more difficult for the buoyancy device to enter the water and easier for it to float, thereby increasing the difficulty of the buoyancy device entering the water and increasing the buoyancy of the buoyancy device, which can further improve the buffering effect against wind and waves and facilitate the repositioning of the float array. In some embodiments, the wing plate 220 may be disposed perpendicular to the anchor line direction. In some embodiments, the wing plate 220 may also include multiple reinforcing structures (not shown in the figure), such as reinforcing ribs, reinforcing plates, and reinforcing stiffeners. This can improve the strength of the wing plate and prevent wind and waves from damaging the wing plate or the buoyancy device.

[0033] In some embodiments, the wing plate 220 and the main body 210 can be movably connected, thereby buffering the impact of wind and waves on the wing plate or buoyancy device, improving the toughness of the buoyancy device and the effect of buffering the impact of wind and waves. In some embodiments, the wing plate 220 may also include multiple parts that are movably connected to each other, similar to the "wings" of a bird, which can further improve the toughness of the buoyancy device and the effect of buffering the impact of wind and waves.

[0034] In some embodiments, other methods to increase the buoyancy of the buoyancy device may also be included. For example, a buoyancy device with a specially designed structure can increase its buoyancy, thereby increasing the resistance to the buoyancy device entering the water and further improving its ability to buffer the impact of wind and waves. In some embodiments, the upper surface of at least a portion of the buoyancy device on the same anchor line (e.g., the buoyancy device away from the float array) may be inclined perpendicular to the anchor line direction, increasing the difficulty of the buoyancy device entering the water and facilitating its exit from the water.

[0035] In some embodiments, the buoyancy device 200 may further include a connecting portion (not shown in the figure), which may be disposed on both sides of the main body 210 and adjacent to the side of the main body where the wing plate is located, and may be used to connect the buoyancy device to the anchor rope and / or the float array. In some embodiments, the connecting portion may be a connecting ring, clamp, etc.

[0036] Figure 3 This is a schematic diagram of a wave-resistant floating array according to another embodiment of this application.

[0037] As shown in the figure, the wave-resistant floating array (hereinafter referred to as "wave-resistant floating array") 300 includes: multiple floats 310, anchoring devices 320, and multiple elastic elements 330. The multiple floats 310 are interconnected to form the floating array 30, which can be used to support solar panels to form a photovoltaic power station, or to support cables or other electrical equipment, or auxiliary facilities such as fences. The anchoring devices 320 can be used to anchor the floating array 30 and also allow the floating array 30 to change position with the waves. In some embodiments, the anchoring devices 320 can be arranged around the floating array. When the floating array changes position with the waves, the anchoring devices on at least one side of the floating array 30 are stressed, allowing the floating array to change position with the waves. In some embodiments, the anchoring devices can be multiple anchor blocks 321 disposed on the seabed.

[0038] Multiple elastic elements 330 are connected between the anchoring device 320 and the floating array 30, and can be used to buffer the impact force (especially instantaneous impact force) of wind and waves on the floating array. When the floating array 30 changes position due to the impact of wind and waves, the elastic elements 330 stretch to reduce the speed and magnitude of the position change. When the multiple elastic elements 330 recover using their elastic force, the floating array can be driven back to its original position. Specifically, when the floating array is impacted by wind and waves, the elastic elements can be gradually stretched to buffer the impact force on the floating array and reduce the possibility of the floating array being torn apart instantly. When the elastic elements are stretched to their limit, they can act as rigidity, cooperating with the anchoring device to anchor the floating array. When the floating array is no longer subjected to impact force, it can elastically return to its original state, thereby also driving the floating array to its reset position. In some embodiments, the elastic elements can be elastic dampers, such as spring dampers. In some embodiments, the elastic elements can also be springs, elastic ropes, etc. The following uses a spring damper as an example to illustrate the technical solution of this application.

[0039] In some embodiments, the anchoring device 320 and the floating array 30 may include one or more anchor lines 301, the connection point of the anchor line 301 and the anchoring device 320 being located underwater, and spring dampers may be disposed on the anchor lines. In some embodiments, the anchor line 301 may also be part of the anchoring device 320. In some embodiments, one anchor line may include one or more spring dampers. According to one embodiment of this application, one anchor line may include two spring dampers. In some embodiments, one anchor line may also have other numbers of spring dampers, such as one, three, four or more. In some embodiments, the specifications of the spring dampers on the same anchor line may be different, thereby adapting to different levels of wind and waves, buffering different wind and waves, and also buffering the same level of wind and waves in stages, thereby improving the buffering effect.

[0040] In some embodiments, the buoyancy device and the elastic element of this application can be used in combination to further enhance the protection and cushioning effect on the floating array. According to a preferred embodiment of this application, when the buoyancy device and the elastic element are used in combination, the buoyancy device is closer to the floating array than the elastic element. Therefore, when waves come, the elastic element can be used for pre-buffering, and the closer proximity of the buoyancy device to the floating array can prevent the edges of the floating array from entering the water.

[0041] The floating array proposed in this application can greatly buffer the impact of wind and waves on the floating array, thereby reducing the impact of wind and waves on the floating array to a certain extent, protecting the floating array, preventing damage to the floating array, making the structure of the floating array more stable, and better able to adapt to the harsh natural environment at sea.

[0042] The above embodiments are for illustrative purposes only and are not intended to limit the invention. Those skilled in the art can make various changes and modifications without departing from the scope of the invention. Therefore, all equivalent technical solutions should also fall within the scope of the invention.
