Description

Technical Field

[0001] This invention belongs to the field of clean energy technology, specifically relating to a levitation device and a high-altitude wind power generation system. Background Technology

[0002] Wind energy, as a clean and renewable energy source, has the advantages of large resource reserves, wide distribution, and high development potential, and has become an important part of the global energy structure transformation.

[0003] The wind power generation technologies in related fields mainly consist of ground-based or near-ground horizontal-axis and vertical-axis wind turbine generators. Their power generation efficiency is largely limited by unfavorable factors such as low wind speeds, strong turbulence, and frequent wind direction changes near the ground. Especially in complex terrain or areas with limited land resources, the site selection and large-scale deployment of wind turbine generators in these technologies face significant limitations. Although some related technologies also explore the development of high-altitude wind energy resources, the controllability of high-altitude equipment is insufficient, making it difficult to ensure system safety and controllability. Summary of the Invention

[0004] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0005] The inventors recognized that wind speed typically increases significantly with altitude, and that mid-to-high-altitude wind fields are characterized by good continuity, directional stability (horizontal direction), and high energy density. Therefore, developing mid-to-high-altitude wind energy resources is considered an important way to improve wind energy utilization efficiency. Consequently, various high-altitude wind power generation technologies have emerged in recent years. These technologies utilize kites, paragliders, rotors, or floating platforms to deploy power generation or power-generating devices in high-altitude wind fields, connecting them to ground equipment via cables to achieve energy transmission or attitude control.

[0006] The inventors also recognized that some existing high-altitude wind power generation equipment uses rotating impellers or high-speed moving parts as the main form of energy harvesting. These systems are complex in structure and difficult to control, and are prone to drastic attitude changes under strong winds or sudden wind direction changes, increasing system fatigue loads and operational risks. Furthermore, some high-altitude wind power systems based on lift or periodic trajectory motion often involve significant vertical heave or large-amplitude spatial movement during their power generation process, resulting in a low effective power generation time ratio, discontinuous energy output, and higher safety and durability requirements for cables and ground equipment.

[0007] The inventors also recognized that current technologies for controlling high-altitude equipment primarily focus on adjusting the overall windward attitude, lacking precise methods for regulating internal airflow paths and pressure distribution. This makes it difficult to achieve stable power output primarily driven by horizontal traction under different wind conditions, thus limiting the efficient conversion of high-altitude wind energy into ground-based mechanical and electrical energy. At the engineering application level, how to reduce ineffective motion and improve the continuity and stability of traction power output while ensuring system safety and controllability remains a pressing technical challenge in the field of high-altitude wind power generation.

[0032] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] See Figures 1 to 9 The levitation device 100 of this embodiment includes a platform body 1, a float 2, and an airflow regulating assembly. The platform body 1 has an airflow channel 11 in its middle, which has a first end and a second end. External airflow can flow into the airflow channel 11 from the first end and out of the airflow channel 11 from the second end. The float 2 is connected to the outside of the platform body 1. The airflow regulating assembly is disposed within the airflow channel 11 and / or on the float 2 to adjust the attitude of the platform body 1.

[0034] When the suspension device 100 is in a mid-to-high altitude environment, airflow can pass through the airflow channel 11. When an airflow regulating component is arranged inside the airflow channel 11, the flow area of ​​different sections within the airflow channel 11 can be adjusted by the airflow regulating component, so that a controllable airflow space is formed within the airflow channel 11. This allows for the adjustment of the air pressure difference in the front-to-back direction of the platform body 1, enabling the entire device to generate a more stable horizontal aerodynamic component under the action of high-altitude winds. The hollow design of the airflow channel 11 can also reduce the weight of the platform body 1.

[0035] When the airflow regulation component is installed on the float 2, the airflow on the surface of the float 2 can be disturbed, thereby adjusting the lift, drag and directional force.

[0036] In this embodiment, airflow adjustment components can be arranged simultaneously on the airflow channel 11 and the floating wing 2. Through the coordinated action of the airflow adjustment components, the performance of the overall structure in terms of windward angle, yaw angle, aerodynamic stability and other aspects can be controlled. Based on the airflow adjustment in the airflow channel 11, the suspension device 100 can be moved along the general horizontal direction to provide a more stable horizontal component and effectively suppress vertical heave or violent swaying in the vertical direction, thereby improving the stability of the system and ensuring that the suspension device 100 can always maintain a motion state dominated by horizontal traction under different wind conditions.

[0037] The suspension device 100 of this embodiment of the invention regulates the airflow near the airflow channel 11 and the wing surface of the floating wing 2 through the airflow regulation component, thereby achieving the regulation of lift, drag and directional force. Through the reasonable design and coordinated control of the airflow regulation component, the platform body 1 and the floating wing 2, it can generate stable horizontal traction force in mid-to-high altitude wind fields and transfer energy to the ground power generation device in a simple and controllable manner, thereby improving the utilization efficiency of high-altitude wind energy and the engineering applicability of the system.

[0038] See Figures 2 to 4 As shown, in some embodiments, the airflow regulating component includes a first airflow regulating component 3, which is disposed within the airflow channel 11 and connected to the platform body 1. The first airflow regulating component 3 is used to regulate the flow area of ​​a corresponding section within the airflow channel 11. By adjusting the flow area at its location, the first airflow regulating component 3 regulates the air pressure difference between the inlet and outlet sides of the airflow regulating component 3, thereby optimizing the magnitude of the horizontal force component of the platform body 1 under the action of wind and improving the stability of the equipment.

[0039] Furthermore, there are multiple first airflow regulating components 3, which are arranged spaced apart from each other along the axial direction of the airflow channel 11. Each of the multiple first airflow regulating components 3 is used to adjust the flow area of ​​a corresponding section in the airflow channel 11, and the multiple first airflow regulating components 3 can operate independently. In this embodiment, the multiple first airflow regulating components 3 can operate independently, thereby dividing the airflow channel 11 into multiple sections. By controlling the air pressure of different sections, the stability of the platform body 1 in the face of complex airflow environment at high altitude is improved, making its controllability higher.

[0040] This embodiment achieves coordinated control of the airflow in the airflow channel 11 by adjusting the flow area at the locations of multiple first airflow adjustment components 3. This enables active adjustment of the attitude of the platform body 1 based on airflow, resulting in strong active control capability, good practicality, and the ability to provide more stable power output, thereby improving the stability and service life of the platform body 1 and the connected traction device 5.

[0041] In some embodiments, the first airflow regulating component 3 includes a first shaft, a first plate 31 and a first driver. Multiple first shafts are arranged side by side and connected to the platform body 1. The first plate 31 is disposed on the first shaft. The first driver is used to drive the first plate 31 to rotate around the axis of the first shaft to adjust the flow gap between the first plates 31 on two adjacent first shafts.

[0042] The first shaft can be rotatably connected to the platform body 1. Multiple first shafts are arranged side by side. The direction of the side-by-side arrangement of the multiple first shafts can be perpendicular to the axis of the airflow channel 11. After the multiple first plates 31 are fixed on the first shaft, they can form a structure similar to louvers. When the first driver drives the first shaft to rotate, the first plate 31 located on the first shaft rotates around the first shaft, thereby making the flow gap between the first plate 31 and the adjacent first plate 31 larger or smaller, realizing the adjustment of the flow area of ​​the airflow.

[0043] At the same time, the airflow will flow along the flow gap between two adjacent first plates 31. The first plate 31 also adjusts the flow direction of the airflow within a small range. The airflow can apply a certain directional force to the first plate 31 so as to adjust the attitude of the platform body 1 by combining the air pressure difference in different sections of the platform body 1 and the directional force acting on the first plate 31.

[0044] There are multiple first actuators, each corresponding to a first shaft, and each first actuator can operate independently. In this embodiment, not only can the multiple first airflow regulating components 3 operate independently, but the multiple first plates 31 located in the same first airflow regulating component 3 can also operate independently, thereby generating more regulating modes, increasing the flexibility of regulation, which is beneficial for dealing with more complex airflow environments and has good practicality.

[0045] The first driver in this embodiment can be a motor, cylinder, or the like, and can be driven by pneumatic force.

[0046] See Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, the airflow adjustment component includes a second airflow adjustment component 4, which is disposed on the float 2. The second airflow adjustment component 4 is used to adjust the airflow direction on the surface of the float 2. The float 2 can generate lift under the action of airflow, and at the same time has a significant impact on the overall stability and maneuverability of the platform body 1. In this embodiment, by setting the second airflow adjustment component 4 on the float 2, the airflow on the surface can be disturbed to obtain and adjust lift, drag and directional force, and actively adjust the stability of the suspension device 100.

[0047] In this embodiment, the first airflow regulating component 3 and the second airflow regulating component 4 can be coordinated to make the suspension device 100 move in a generally horizontal direction.

[0048] The second airflow regulating component 4 can be installed on one side of the wing surface of the float 2, or it can be installed on each wing surface of the float 2. Figure 5 A schematic diagram is shown of the second airflow regulating component 4 disposed on one side of the wing surface of the float 2. Figure 6 A schematic diagram is shown showing the second airflow regulating assembly 4 disposed on the wing surfaces on opposite sides of the float 2.

[0049] Furthermore, there are multiple second airflow regulating components 4. The wing surface of the floating wing 2 includes an upper wing surface and a lower wing surface. Some of the multiple second airflow regulating components 4 are located on the upper wing surface, and another part of the multiple second airflow regulating components 4 is located on the lower wing surface. The multiple airflow regulating components can operate independently.

[0050] The float 2 is generally flat and plate-shaped. Multiple second airflow regulating components 4 are provided on both the upper and lower surfaces of the float 2, thereby enabling the disturbance of airflow on the upper and lower surfaces of the float 2 and allowing for more precise control of the force exerted by the airflow on the float 2.

[0051] In this embodiment, multiple second airflow adjustment components 4 can be distributed at different positions on the wing surface and can operate independently. By actively adjusting the airflow at different positions on the wing surface, the stability of the floating wing 2 under force can be ensured, the shape retention is better, and problems such as local stress concentration and bending deformation can be avoided.

[0052] In some embodiments, the second airflow regulating assembly 4 includes a second shaft, a second plate 41, and a second driver. A plurality of second shafts are connected to the float 2, the second plate 41 is connected to the second shaft, and the second driver is used to drive the second plate 41 to rotate about the axis of the second shaft to adjust the tilt angle of the second plate 41 relative to the float 2.

[0053] The second shaft can be rotatably connected to the float 2. The second plate 41 is fixed on the second shaft. The second driver is used to drive the second shaft to rotate and drive the second plate 41 to rotate. This allows the second plate 41 to be in contact with and roughly parallel to the wing surface of the float 2, or to make the second plate 41 and the wing surface of the float 2 form a preset angle. The angle between the second plate 41 and the wing surface of the float 2 can be from 0 degrees to 90 degrees, adjusting the airflow state at the corresponding position, changing the force on the float 2, so as to cope with changes in the surrounding environment and ensure the overall stability of the suspension device 100.

[0054] In this embodiment, the second driver can be a motor, cylinder, etc., while the first driver can be driven by pneumatic force.

[0055] Furthermore, multiple second airflow regulating components 4 located on the same wing surface of the float 2 are arranged spaced apart from each other in a direction away from the platform body 1. The second plate 41 can be generally elongated. In the initial state, the multiple second plates 41 can be arranged in a generally parallel manner, and the length direction of the second plate 41 can be arranged at an angle to the front-rear direction of the platform body 1. One side of the width direction of the second plate 41 can be rotatably connected to the float 2. In this embodiment, by designing the arrangement of the second plates 41, the airflow on the wing surface can be better regulated and finely disturbed, reducing the impact of unstable airflow on the stability of the suspension device 100.

[0056] like Figure 7 As shown, in some embodiments, a portion of the plurality of second airflow regulating components 4 are located on the outside of the platform body 1, and the plurality of second airflow regulating components 4 are arranged circumferentially on the platform body 1. For example, a plurality of second airflow regulating components 4 are arranged along the front-back direction on the upper surface of the platform body 1, and a plurality of second airflow regulating components 4 can also be arranged along the front-back direction on the lower surface of the platform body 1.

[0057] Of course, a second airflow regulating component 4 can also be arranged on the left and right sides of the platform body 1 according to the actual application.

[0058] This embodiment can flexibly control the movement direction of the suspension device 100 by controlling the swing angle of different airflow adjustment components. The suspension device 100 can move in the front-back direction, or in the left-right direction, or in the up-down direction, or from the left front to the right rear, or from the top front to the bottom rear, etc. This embodiment has higher adjustment flexibility for the suspension device 100 and better controllability of its movement trajectory.

[0059] In some embodiments, the platform body 1 is columnar or spindle-shaped, and the airflow channel 11 is located in the middle of the platform body 1. The axial direction of the airflow channel 11 is parallel to the horizontal direction, or the axial direction of the airflow channel 11 is at a preset angle to the horizontal direction.

[0060] The platform body 1 can be roughly cylindrical, and the airflow channel 11 in the middle of the platform body 1 can also be roughly cylindrical.

[0061] Alternatively, the platform body 1 may be generally spindle-shaped, and the cross-sectional area of ​​the two ends of the platform body 1 that are orthogonal to the axial direction of the platform body 1 is smaller than that of the middle part of the platform body 1. In this case, the airflow channel 11 in the middle of the platform body may also be generally cylindrical.

[0062] The overall axial length of the platform body 1 in this embodiment can be determined according to the design power and the usage height. The axial direction of the platform body 1 is roughly parallel to the horizontal plane. When the axial direction of the airflow channel 11 is at a preset angle to the horizontal direction, the preset angle can be 5 degrees, 10 degrees, 15 degrees, etc. By reasonably controlling the angle between the airflow channel 11 and the horizontal direction, the attitude of the suspension device 100 can be better controlled, and the work efficiency can be improved.

[0063] Optionally, the platform body 1 and the floating wing 2 are inflatable airbags. A support ring 12 is provided on the side wall of the airflow channel 11. The airflow regulating component located in the airflow channel 11 is connected to the support ring 12. The support ring 12 can improve the structural stability of the airflow channel 11 and provide support for the airflow regulating component, facilitating its fixation, making assembly convenient and improving stability. After inflation, the levitation device 100 can easily rise and levitate. The volume of the platform body 1 and the floating wing 2 can be determined according to the power generation capacity to provide greater traction under the action of medium and high airflow.

[0064] Optionally, there are multiple floating wings 2, which are arranged around the circumference of the platform body 1. When there are two floating wings 2, they are arranged in a generally horizontal manner, and the two floating wings 2 can be arranged on opposite left and right sides of the platform body 1.

[0065] In this embodiment, the platform body 1 is provided with a plurality of traction parts 13. The traction parts 13 are used to connect with ground equipment. The traction parts 13 can be arranged at intervals along the axial direction of the platform body 1. The traction parts 13 can be hooks and loops, which facilitate connection with the traction rope of the traction device 5.

[0066] The inventors recognized that existing wind power generation technologies mainly focus on the development of ground-level or near-ground wind resources, and are limited in overall energy utilization efficiency due to factors such as low wind speed, strong turbulence, and frequent changes in wind direction. Although various high-altitude wind power generation technologies have attempted to utilize mid-to-high-altitude wind fields, existing solutions generally suffer from problems such as complex structures, insufficient operational stability, and high control difficulty. Furthermore, in actual operation, they are often accompanied by significant vertical heave or irregular spatial movements, resulting in a low effective work time ratio, discontinuous energy output, and significant dynamic loads and safety hazards on the traction cable 51 and ground equipment. In addition, existing high-altitude wind power generation systems rely heavily on overall attitude or trajectory changes to obtain energy, lacking effective control over the airflow path and pressure distribution within the high-altitude dynamic structure. This makes it difficult to stably generate work output primarily based on horizontal traction force under different wind conditions, thus limiting the efficient and controllable conversion of high-altitude wind energy into ground mechanical and electrical energy.

[0067] See Figure 8 and Figure 9As shown, the high-altitude wind power generation system 200 of this embodiment includes a suspension device 100, ground equipment, and a traction device 5. The suspension device 100 is any of the suspension devices described above, and the traction device 5 is located between the suspension device 100 and the ground equipment. The ground equipment includes a mechanical winch 6, a generator 7, a controller 8, and an energy storage device 9 connected to each other. The controller 8 is electrically connected to the mechanical winch 6, the generator 7, and the energy storage device 9, thereby controlling the mechanical winch 6, the generator 7, and the energy storage device 9 to work together. The mechanical winch 6 is connected to the traction device 5 and the generator 7, and can transmit the force exerted by the traction device 5 on the mechanical winch 6 to the generator 7 to generate electricity. The energy storage device 9 can store and redistribute electricity.

[0068] In this embodiment of the invention, the suspension device 100 is connected to ground equipment such as the generator 7 and mechanical winch 6 on the ground by a traction device 5 such as a cable 51. Through aerodynamic modulation and traction conversion of high-altitude wind energy, efficient and stable wind power generation is achieved.

[0069] The platform body 1 has one or more sets of controllable first airflow adjustment components 3 installed in the hollow cylindrical airflow channel 11. These components are used to adjust the flow area and pressure distribution of different sections of the internal airflow channel 11, so that the platform body 1 can generate aerodynamic output mainly in the horizontal direction under the action of high-altitude wind. The floating wing 2 has an aerodynamic shape similar to an aircraft wing, and adjustable plate-shaped second airflow adjustment components 4 are installed on its surface. By changing the opening angle of the second plate 41 and the combination of multiple second plates 41, the overall windward angle, motion direction and aerodynamic stability can be adjusted. The components work together with the first airflow adjustment components 3 to form a controllable and continuous traction work state.

[0070] During system operation, the suspension device 100 mainly moves in an orderly manner along the horizontal direction in the mid-to-high altitude wind field. The resulting traction force is transmitted to the ground power generation and mechanical equipment through the traction cable 51, driving the mechanical transmission mechanism and generator 7 to achieve power output.

[0071] like Figure 8 As shown, the traction cable 51 of the traction device is connected to the middle of the platform body 1 of the suspension device 100. Multiple traction units can be arranged on the platform body 1, so that there are multiple connection points between the traction cable 51 and the platform body 1.

[0072] like Figure 9 As shown, the traction cable 51 of the traction device is connected to the front end of the platform body 1 of the suspension device 100. A connection point can be provided between the traction cable 51 and the platform body.

[0073] In some embodiments, the high-altitude wind power generation system 200 includes a monitoring component and a control component. The monitoring component is used to acquire environmental information and operating status information of the suspension device 100, ground equipment and traction device 5. The control component is used to adjust the attitude of the suspension device 100 and the operating parameters of the ground equipment based on the environmental information and operating status information.

[0074] The monitoring and control components coordinate and control the levitation device and ground equipment based on real-time wind conditions, traction force changes, and structural attitude information. This ensures the system maintains stable operation under varying wind speeds and directions, effectively suppressing ineffective movements such as vertical heave and violent swaying. Through the comprehensive design of the above structure and control methods, this invention realizes the conversion of high-altitude wind energy from unstable airflow into controllable traction energy, improving the utilization efficiency of high-altitude wind energy and the reliability of system operation. It has good engineering adaptability and application value.

[0075] The embodiments of the present invention can reduce ineffective vertical motion and drastic attitude changes while ensuring system safety and controllability, thereby achieving stable traction work and continuous power generation of high-altitude wind energy.

[0076] The cable in this embodiment of the invention can be made of high-strength, low-elongation composite materials, such as aramid fiber, ultra-high molecular weight polyethylene fiber, or their composite structure, possessing both load-bearing capacity and fatigue resistance. One end of the cable is connected to the traction part (main force-bearing node) of the suspension device, and the other end of the cable is connected to the ground mechanical winch, used to transmit horizontal traction force and control the system's height and range of motion.

[0077] The ground equipment also includes transmission components and energy buffering and braking devices. When the suspension device generates horizontal traction under the influence of high-altitude winds, the traction cable drives the mechanical winch to rotate. The mechanical winch, through the transmission components, drives the generator to generate electricity, realizing the conversion of mechanical energy into electrical energy. The mechanical winch can be extended and retracted according to the system control strategy to maintain continuous and stable energy output. The energy buffering and braking devices ensure the stability and continuity of the overall power transmission and conversion, improving the system's stability.

[0078] The monitoring data of the monitoring component in this embodiment includes: high-altitude wind speed, wind direction, tension of traction cable, attitude of suspension device, internal pressure of airbag, and operating status of ground equipment.

[0079] The control logic of the control component is to coordinate and control the following components based on real-time monitoring data: The opening angles of multiple first plates in multiple first airflow regulating components, the deflection angles of multiple second plates in multiple second airflow regulating components, the take-up and release speed and braking torque of the ground mechanical winch, etc., through the above control methods, enable the suspension device to always maintain a state of operation that mainly performs horizontal traction work under different wind conditions, effectively suppressing vertical heave and violent swaying, and improving system stability.

[0080] During system operation, the levitation device is raised to a set height and enters a stable wind field. Under the control of the control system, the first and second airflow regulation components form a coordinated aerodynamic state, enabling the structure to generate a stable horizontal traction force under the influence of high-altitude winds. This traction force is transmitted to the ground mechanical winch via a traction cable, driving the generator to produce electricity. By continuously adjusting the operating strategies of the first and second airflow regulation components and the mechanical winch, the system can maintain continuous and stable energy output under different wind speeds and directions.

[0081] Compared to solutions in related technologies, this invention, by setting the platform body as an inflatable bladder and arranging a first airflow regulating component within the airflow channel, can adjust the internal airflow channel and air pressure distribution under the influence of high-altitude winds, ensuring that the levitation device primarily generates horizontal aerodynamic components during operation. Compared to existing high-altitude wind power systems that rely mainly on rotating impellers or periodic trajectory motion, this invention can significantly reduce ineffective vertical heave motion of the structure, reducing the vertical dynamic load amplitude by approximately 30% to 50%, which is beneficial for reducing fatigue damage to the traction cable and improving the long-term operational reliability of the system.

[0082] Secondly, the floating wing and the second airflow adjustment component in this embodiment of the invention achieve active control over the overall structural attitude and traction direction by changing the angle of attack and aerodynamic characteristics. Compared with existing technologies that rely solely on overall attitude or passive aerodynamic stabilization, this structure can maintain a more stable traction direction under changing wind conditions, significantly reducing the fluctuation amplitude of traction cable tension. Especially under moderate turbulent wind conditions, the instantaneous fluctuation amplitude of traction force can be reduced to within ±15% to 25% of the average traction force, thereby contributing to the stable operation of ground equipment.

[0083] Furthermore, this embodiment of the invention employs a cable-mechanical winch-generator energy conversion method to transform high-altitude wind energy into controllable mechanical energy output on the ground. Compared to a scheme that directly places the generator at high altitude, this effectively reduces high-altitude load and structural complexity, and minimizes the risk of failure of high-altitude electrical equipment. Under the same rated power conditions, the structural weight of the high-altitude portion of the system can theoretically be reduced by 20% to 40%, which is beneficial for increasing the system's altitude and the range of applicable wind fields.

[0084] Furthermore, through the coordinated control of the operating states of the first airflow regulation component, the second airflow regulation component, and the mechanical winch by the control and monitoring components, this invention can dynamically adjust the working state according to changes in wind speed and direction, enabling the system to maintain stable operation over a wide wind speed range. The effective working wind speed range of this system can be extended to 5–25 m / s, significantly improving the proportion of continuous and stable working time compared to some existing high-altitude wind power solutions.

[0085] Finally, the overall structure of this invention adopts an inflatable lightweight configuration and modular design, with a clear force path and simple structural form. This not only helps to reduce manufacturing and maintenance costs, but also facilitates large-scale deployment and power level expansion. It is suitable for various terrains and application scenarios and has good engineering promotion value.
