Description

Technical Field

[0001] The present invention relates to the technical field of aerial power generation equipment, and in particular to an energy-gathering cover of a floating power generation platform and a floating power generation platform. Background Art

[0002] As the global demand for renewable energy continues to increase, high-altitude wind power has become a highly promising energy development method. High-altitude wind power systems take advantage of the more stable airflow and higher wind speed at high altitudes, which can significantly improve the efficiency and total power generation of wind power generation. However, existing floating power generation platforms mostly use wind turbines equipped with floating air bags, relying on the floating air bags to fly high in the sky to generate wind power. The wind speed obtained by the wind turbines in existing floating power generation platforms is usually the natural wind speed. Under low wind speed conditions, the power generation efficiency of the floating power generation platform is low.

[0003] That is to say, the floating power generation platform in the prior art has the problem of low power generation efficiency. Summary of the invention

[0004] The main purpose of the present invention is to provide an energy-gathering cover for a floating power generation platform and a floating power generation platform, so as to solve the problem of low power generation efficiency of the floating power generation platform in the prior art.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a floating power generation platform energy collecting cover is provided, comprising: an energy collecting frame, which is an annular structure, and the inner diameter of the energy collecting frame first decreases and then increases along a first direction; a skin, and the skin cover is arranged on the energy collecting frame.

[0006] Further, a ratio of a width C of the energy concentrating frame in the first direction to a minimum radius R of the energy concentrating frame is greater than or equal to 0.5 and less than or equal to 2.

[0007] Furthermore, the energy concentrating frame has a first end face and a second end face that are arranged opposite to each other, the inner diameter of the first end face is smaller than the inner diameter of the second end face, and the position of the minimum inner diameter of the energy concentrating frame is close to the first end face relative to the second end face.

[0008] Further, a ratio of a distance L between a position where the minimum inner diameter of the energy concentrating frame is located and the first end surface in the first direction to a width C of the energy concentrating frame in the first direction is greater than or equal to 0.15 and less than or equal to 0.3.

[0009] Furthermore, the energy focusing frame includes: a plurality of energy focusing rings, which are arranged at intervals along the first direction; and a plurality of connecting ribs, which are located between two adjacent energy focusing rings, and whose two ends are respectively connected to the two adjacent energy focusing rings.

[0010] Further, at least two energy focusing rings have different widths; and / or at least two energy focusing rings have different diameters.

[0011] Furthermore, the width of the energy focusing ring located in the middle of the multiple energy focusing rings is greater than the width of the energy focusing rings located at the edge; and / or in the first direction, the arrangement density of the energy focusing rings located in the central area is greater than the arrangement density of the energy focusing rings located in the edge areas on both sides.

[0012] Furthermore, a plurality of connecting ribs between two adjacent energy focusing rings are arranged at equal intervals.

[0013] Furthermore, the structural strength of the energy-gathering frame is greater than or equal to 1 GPa; the density of the energy-gathering frame is greater than or equal to 1.4 g / cm 3 And less than or equal to 2g / cm 3 .

[0014] According to another aspect of the present invention, there is provided a floating power generation platform, comprising the above-mentioned floating power generation platform energy collecting cover.

[0015] By applying the technical solution of the present invention, the energy-gathering cover of the floating power generation platform includes an energy-gathering frame and a skin. The energy-gathering frame is an annular structure, and the inner diameter of the energy-gathering frame first decreases and then increases along a first direction; the skin cover is arranged on the energy-gathering frame.

[0016] By setting the inner diameter of the energy-gathering frame to be not in a shape that first decreases and then increases along the first direction, this design utilizes aerodynamics. When the wind flows through the central channel of the energy-gathering frame, the wind flows will accelerate in the contraction section because the energy-gathering frame contracts first and then expands, thereby significantly increasing the wind speed when passing through the central channel. The wind turbine unit is located in the central channel, which further significantly increases the wind speed when passing through the wind turbine unit, improves the efficiency of wind power generation, and improves the utilization rate of wind energy. The increase in wind speed means that more wind energy can be captured by the wind turbine unit, especially under low wind speed conditions. This design can significantly improve the power generation efficiency and expand the operating adaptability range of the floating power generation platform.

[0017] The energy-gathering frame of the present application adopts an annular structure, and its inner diameter shows a trend of decreasing first and then increasing along the first direction. This design can effectively guide and converge wind flow. When the wind flow passes through the area where the inner diameter gradually decreases, the wind speed is accelerated, thereby increasing the wind energy density; subsequently, the wind flow gradually decelerates in the area where the inner diameter increases, which is conducive to the stable operation of the wind turbine unit and the effective conversion of energy. This unique structural design helps to significantly improve the wind energy capture rate. Compared with the traditional linear or single curvature energy-gathering cover, the present invention can maintain a high energy conversion efficiency in a wider wind speed range. This design can effectively capture and focus high-altitude wind energy, improve the efficiency of wind power generation, and is particularly suitable for areas with rich but difficult-to-use high-altitude wind resources, such as oceans and remote mountainous areas. Through this unique energy-gathering design, the wind energy capture efficiency is significantly improved, which can not only provide efficient energy solutions for areas with rich high-altitude wind energy resources such as offshore wind power stations and mountain wind power projects, but also maintain a certain power generation efficiency in an environment with low wind speeds, broadening the application scope of wind power generation.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0026] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0027] In order to solve the problem of low power generation efficiency of floating power generation platforms in the prior art, the present invention provides an energy gathering cover of a floating power generation platform and a floating power generation platform.

[0028] like Figures 1 to 3 As shown, the energy-gathering cover of the floating power generation platform includes an energy-gathering frame 10 and a skin 20 . The energy-gathering frame 10 is an annular structure, and the inner diameter of the energy-gathering frame 10 first decreases and then increases along a first direction; the skin 20 is covered on the energy-gathering frame 10 .

[0029] By setting the inner diameter of the energy-gathering frame 10 to not present a shape that first decreases and then increases along the first direction, this design utilizes aerodynamics. When the wind flow passes through the central channel of the energy-gathering frame 10, the wind flow will accelerate in the contraction section because the energy-gathering frame 10 first contracts and then expands, thereby significantly increasing the wind speed when passing through the central channel. The wind turbine unit is located in the central channel, which further significantly increases the wind speed when passing through the wind turbine unit, improves the efficiency of wind power generation, and improves the utilization rate of wind energy. The increase in wind speed means that more wind energy can be captured by the wind turbine unit, especially under low wind speed conditions. This design can significantly improve the power generation efficiency and expand the operating adaptability range of the floating power generation platform.

[0030] The energy-gathering frame 10 of the present application adopts an annular structure, and its inner diameter shows a trend of decreasing first and then increasing along the first direction. This design can effectively guide and converge wind flow. When the wind flow passes through the area where the inner diameter gradually decreases, the wind speed is accelerated, thereby increasing the wind energy density; subsequently, the wind flow gradually decelerates in the area where the inner diameter increases, which is conducive to the stable operation of the wind turbine set and the effective conversion of energy. This unique structural design helps to significantly improve the wind energy capture rate. Compared with the traditional linear or single curvature energy-gathering cover, the present invention can maintain a high energy conversion efficiency in a wider wind speed range. This design can effectively capture and focus high-altitude wind energy, improve the efficiency of wind power generation, and is particularly suitable for areas with rich but difficult-to-use high-altitude wind resources, such as oceans and remote mountainous areas. Through this unique energy-gathering design, the wind energy capture efficiency is significantly improved, which can not only provide efficient energy solutions for areas with rich high-altitude wind energy resources such as offshore wind power stations and mountain wind power projects, but also maintain a certain power generation efficiency in an environment with low wind speeds, broadening the application scope of wind power generation.

[0031] In addition, the skin 20 is covered on the energy-gathering frame 10 to cover the gaps on the energy-gathering frame 10 to prevent air leakage from the energy-gathering frame 10 and ensure that the floating power generation platform can float.

[0032] In some alternative embodiments, see Figure 2 , the ratio of the width C of the energy concentrating frame 10 in the first direction to the minimum radius R of the energy concentrating frame 10 is greater than or equal to 0.5 and less than or equal to 2. When the ratio of the width C to the minimum radius R is within the set range, the geometric shape of the energy concentrating frame 10 can more effectively guide and focus the wind flow, forming a wind energy convergence area, thereby increasing the wind speed in the central channel and significantly improving the wind energy capture efficiency. This is because the appropriate C / R ratio can reduce the diffusion of the wind flow when entering the energy concentrating cover, so that more wind energy can be concentrated on the wind wheel or other energy conversion devices, thereby enhancing the power generation capacity. The optimization of this ratio can also reduce the lateral leakage of wind energy, ensure the maximum utilization of wind power in the direction perpendicular to the wind wheel, and thereby increase the speed and output power of the wind wheel. This ratio design can ensure the stability of the energy concentrating frame 10 at different wind speeds and wind directions. The proportional relationship between the width C and the minimum radius R directly affects the wind resistance and structural rigidity of the energy concentrating frame 10. A reasonable C / R ratio can keep the energy-gathering frame 10 in good shape when subjected to high wind speeds, reduce the swing and deformation caused by wind force, and thus improve the stability and safety of the entire power generation system. In addition, the increase in width C helps to disperse the concentrated effect of wind force on the energy-gathering frame 10, avoid local overload, reduce structural fatigue, and extend the service life of the energy-gathering cover.

[0033] In addition, the size and shape of the energy-gathering frame 10 have a direct impact on the layout and efficiency of the energy conversion device (such as a generator or an electric energy transmission system) connected thereto. Controlling the C / R ratio within the above range helps to provide a more reasonable installation space for the energy conversion device while maintaining the efficient wind capture of the energy-gathering cover, reduce mechanical friction and energy loss, and improve the overall energy conversion rate. A relatively stable wind environment is formed in the energy-gathering cover, which is conducive to the smooth operation of the wind wheel, thereby improving the stability and quality of the electric energy output and providing a more reliable energy supply for the ground power system.

[0034] In some optional embodiments, such as Figures 1 to 3As shown, the energy concentrator body 10 has a first end face 11 and a second end face 12 which are arranged opposite to each other, the inner diameter of the first end face 11 is smaller than the inner diameter of the second end face 12, and the position of the minimum inner diameter of the energy concentrator body 10 is close to the first end face 11 relative to the second end face 12. The larger inner diameter at the second end face 12 provides a more stable airflow environment for the wind wheel, avoiding the direct influence of the high-altitude wind speed fluctuation. At the same time, the smaller inner diameter at the first end face 11 helps to reduce the leakage of wind energy, ensuring that more wind energy is efficiently guided to the wind wheel, thereby improving the speed and power generation efficiency of the wind wheel. The design of the energy concentrator body 10 that first decreases and then increases from the first end face 11 to the second end face 12 is similar to a wind tunnel or a trumpet-shaped structure, which can effectively gather and guide the airflow, concentrate the originally dispersed wind energy into a smaller area, thereby significantly improving the capture efficiency of wind energy. This design principle is similar to some phenomena in nature, such as the wind speed enhancement effect of valleys or canyons, and realizes the concentration and acceleration of wind energy through the contraction and expansion of physical space.

[0035] In addition, setting the minimum inner diameter of the energy-gathering frame 10 near the first end face 11 can reduce the structural stress caused by wind speed changes, which helps to improve the structural stability and safety of the entire floating power generation platform. This design can be regarded as a fluid mechanics optimization, which reduces the impact on the structure by controlling the convergence point and velocity distribution of the airflow, and achieves a smoother and continuous wind energy guidance process.

[0036] In some alternative embodiments, see Figure 2 , the ratio of the distance L between the minimum inner diameter of the energy concentrating frame 10 and the first end face 11 in the first direction to the width C of the energy concentrating frame 10 in the first direction is greater than or equal to 0.15 and less than or equal to 0.3. Controlling the L / C ratio within a specific range can optimize the wind flow dynamics inside the energy concentrating frame. When the wind flow enters the energy concentrating cover, it will experience an acceleration effect at the minimum inner diameter, and then slow down as the diameter increases, forming a geometric structure similar to a venturi tube. This design helps to efficiently converge and guide the wind flow, reduce the loss of wind energy, and ensure that the wind wheel or other energy conversion device can receive the maximum wind energy input. The acceleration and deceleration process of the wind flow not only increases the wind speed, but also improves the windward angle of the wind wheel, thereby improving the energy conversion efficiency. By accurately controlling the L / C ratio, the energy concentrating frame 10 can obtain better structural stability. In a high-altitude environment, wind power generation platforms are subject to various extreme weather conditions, such as strong winds, temperature changes, and ultraviolet radiation. A properly designed L / C ratio helps to disperse the impact of wind on the energy-gathering frame 10, reduce deformation and vibration under the action of wind, and ensure that the energy-gathering cover can still maintain its shape and function in a complex environment.

[0037] In addition, the L / C ratio is controlled between 0.15 and 0.3, so that the energy-gathering hood can better adapt to the changing wind conditions at high altitudes. This design can not only remain stable under strong wind conditions, but also maintain a high wind energy capture efficiency at lower wind speeds, ensuring the continuous and efficient operation of the power generation platform under different wind conditions. This adaptability of the energy-gathering hood is crucial to improving the overall performance and reliability of the power generation system, especially in high-altitude environments with large fluctuations in wind resources.

[0038] In some optional embodiments, such as Figure 1 and Figure 3 As shown, the energy-gathering frame 10 includes a plurality of energy-gathering rings 13 and a plurality of connecting ribs 14, wherein the plurality of energy-gathering rings 13 are arranged at intervals along the first direction; the connecting ribs 14 are located between two adjacent energy-gathering rings 13, and the two ends of the connecting ribs 14 are respectively connected to the two adjacent energy-gathering rings 13. The energy-gathering frame 10 adopts a plurality of energy-gathering rings 13 arranged at intervals along the first direction, and at the same time forms a frame with a hollow area through the connecting ribs 14, which reduces the weight of the energy-gathering frame 10 while ensuring the structural strength of the energy-gathering frame 10, thereby reducing the load of the floating power generation platform, and facilitating the floating power generation platform to float to a higher position. In addition, arranging a plurality of energy-gathering rings 13 in the first direction (i.e., the mainstream direction of the wind) in combination with the skin 20 can form a continuous wind energy convergence channel. At least one energy-gathering ring 13 reduces the cross-sectional area of ​​the airflow to a certain extent, thereby accelerating the wind speed passing therethrough, and realizing the effective gathering of wind energy. The presence of the connecting ribs 14 ensures the structural continuity and stability between the energy focusing rings 13, prevents the energy focusing rings 13 from being displaced or deformed under the action of wind, and further ensures the effect of capturing wind energy.

[0039] In addition, the design of combining multiple energy-gathering rings 13 arranged at intervals with connecting ribs 14 significantly enhances the overall structural stability of the energy-gathering frame 10. The energy-gathering rings 13 and connecting ribs 14 form a stable frame that can effectively disperse the impact of wind, reduce structural vibration and swing, and ensure the safe operation of the power generation system in a strong wind environment.

[0040] In some optional embodiments, such as Figure 1 and Figure 3 As shown, at least two energy-gathering rings 13 have different widths. This arrangement can be designed according to the different requirements for support performance at different positions of the floating power generation platform, which is conducive to improving the diversity of the structural design of the energy-gathering frame 10. A wide energy-gathering ring 13 can be used at a position with high requirements for structural strength, and a small energy-gathering ring 13 can be used at a position with low requirements for structural strength. The energy-gathering frame 10 formed in this way is lighter in weight while ensuring structural strength, which is conducive to the floating power generation platform floating to a higher position.

[0041] For example, the width of the energy focusing ring 13 in the middle of the multiple energy focusing rings 13 is greater than the width of the energy focusing rings at the edge, so as to ensure the structural strength of the energy focusing frame 10. Usually, the middle position of the energy focusing frame 10 needs to support the fan assembly, so the width of the energy focusing ring 13 in the middle is greater than the width of the energy focusing ring 13 at the edge.

[0042] By adjusting the width distribution of the energy focusing ring 13, the structural stability and strength of the energy focusing frame 10 can be enhanced while ensuring lightweight. The width of the energy focusing ring 13 located in the middle is set to be larger than the width of the energy focusing ring 13 located at the edge, which can optimize the load distribution of the entire energy focusing frame 10 and reduce the load borne by the edge energy focusing ring, thereby reducing the vibration and deformation of the entire structure and improving the wind resistance of the system. This layout can also disperse wind force to a certain extent, avoid local overload, and ensure the reliable operation of the energy focusing cover in a complex environment at high altitude.

[0043] In some optional embodiments, such as Figure 1 As shown, at least two energy focusing rings 13 have different diameters. The distribution of energy focusing rings 13 with different diameters is arranged in this way, which is conducive to the inner diameter of the central channel of the energy focusing cover of the floating power generation platform being formed to be first reduced and then increased. By adjusting the diameter difference between different energy focusing rings 13, the airflow dynamics performance can be optimized, the turbulence and resistance of the wind flow when passing through the energy focusing cover can be reduced, and the transmission efficiency of wind energy can be improved.

[0044] In some optional embodiments, in the first direction, the arrangement density of the energy focusing rings 13 located in the central area is greater than the arrangement density of the energy focusing rings 13 located in the edge areas on both sides. The high-density arrangement of the energy focusing rings 13 in the central area improves the wind resistance of the entire energy focusing cover by increasing the compactness and strength of the structure. A stable support network is formed between the dense energy focusing rings 13 and the connecting ribs 14, which can more evenly disperse the impact of wind force, reduce the vibration and deformation of the structure, and ensure the stable operation of the entire power generation system in a complex wind environment at high altitude. In addition, this design can also effectively reduce the non-uniform effect of wind force on the wind wheel and improve the overall reliability and safety of the power generation system.

[0045] In some optional embodiments, a plurality of connecting ribs 14 located between two adjacent energy focusing rings 13 are arranged at equal intervals. The connecting ribs 14 arranged at equal intervals can evenly distribute and transfer wind loads, ensure that the connection between the energy focusing rings 13 is more stable, and reduce structural deformation or damage caused by local wind changes. This uniform structural support improves the overall rigidity and stability of the energy focusing cover, enabling it to withstand more complex and stronger wind conditions at high altitudes, reducing the risk of structural failure. This evenly distributed connecting rib 14 design can ensure that the energy focusing cover maintains structural stability and efficient use of wind energy when facing wind forces from different directions, and is suitable for areas where wind direction changes frequently, such as islands, open areas, etc. In an environment where wind direction changes frequently, the evenly distributed connecting rib 14 design can enhance the overall stability of the energy focusing cover, reduce the impact of wind on the structure, and ensure the continuity and stability of wind energy conversion.

[0046] In some optional embodiments, the structural strength of the energy-gathering frame 10 is greater than or equal to 1 GPa; the density of the energy-gathering frame 10 is greater than or equal to 1.4 g / cm 3 And less than or equal to 2g / cm 3 . The optimization of structural strength ensures the stability and reliability of the energy-gathering frame in complex high-altitude environments. Under harsh conditions such as strong winds, temperature changes, and ultraviolet radiation, the energy-gathering frame with sufficient strength can resist the effects of external forces, reduce the risk of structural deformation and fracture, and ensure the continuous operation of the power generation system. At the same time, the setting of the upper limit of strength avoids the problem of excessive use of high-strength materials leading to increased costs and excessive weight, ensuring the economy and lightweight design of the structure. The density of the energy-gathering frame 10 is controlled between 1.4 and 2, aiming to achieve a balance between lightweight and high strength. The application of lightweight materials can reduce the overall weight of the floating platform, reduce the cost and energy consumption of the launch, while reducing wind resistance and improving floating efficiency. However, too low a density may result in insufficient structural strength and difficulty in withstanding the forces in the high-altitude environment. By reasonably adjusting the density range, this design ensures that the energy-gathering frame has sufficient structural strength while maintaining its lightweight, thereby enhancing its safety and economy in high-altitude operations.

[0047] In addition, the lightweight design helps reduce the energy consumption of the floating platform, while the sufficiently strong structure ensures the long life cycle and low maintenance cost of the system, thereby improving the overall energy efficiency. The lightweight and high-strength energy-gathering frame reduces the demand for buoyancy materials, reduces energy consumption, and also reduces the power loss of the platform caused by wind, thus improving the conversion efficiency of wind energy to electrical energy.

[0048] like Figure 2 and Figure 3 As shown, the minimum inner diameter of the energy-gathering frame 10 is located at different positions, that is, the curvature of the energy-gathering cover of the floating power generation platform is different, and can be designed according to actual usage requirements.

[0049] It should be noted that the skin 20 may be disposed only on the inner side of the energy concentrating frame 10, or the skin 20 may be disposed only on the inner side of the energy concentrating frame 10, or the skin 20 may be disposed on both the inner side and the outer side of the energy concentrating frame 10. The material of the skin 20 may be glass fiber or carbon fiber cloth.

[0050] In some optional embodiments, the floating power generation platform includes the above-mentioned floating power generation platform energy collection cover. By applying the above-mentioned optimized energy collection cover to the floating power generation platform, the wind energy capture and conversion efficiency of the platform can be significantly improved, providing new possibilities for the development and utilization of clean energy. This floating power generation platform can not only provide electricity for areas that are difficult to cover on the ground, but also can be used as an emergency power supply, a mobile power supply, etc., and play an important role in disaster relief, power supply for large-scale activities, etc., and has broad application prospects and market potential. In actual deployment, this floating power generation platform can not only provide timely power support for rescue work after natural disasters such as earthquakes and typhoons, but also serve as a concealed energy supply station in action to provide reliable power for front-line troops. In addition, when holding large-scale events, such as sports events, concerts, etc., the floating power generation platform can provide temporary and efficient power solutions, reduce dependence on traditional fossil energy, and promote social activities to develop in a more environmentally friendly and sustainable direction.

[0051] The floating power generation platform in this application significantly improves the efficiency of wind energy capture and conversion and enhances the stability and safety of the system through the innovative design of the high-altitude power generation floating platform energy-gathering cover.
