Description

Technical Field

[0001] This specification relates to the field of wind power generation technology, specifically to an airship, an airship air operation control system, and a wind power generation device. Background Technology

[0002] Against the backdrop of continuously growing energy demand and increasingly stringent environmental protection requirements, the development and utilization of renewable and clean energy has become a key development direction in the global energy sector. Wind energy, as a renewable energy source with abundant reserves, wide distribution, and no pollution, has received much attention and achieved significant development in recent years.

[0003] Currently, tower wind power technology is one of the mainstream methods for wind energy utilization, but this technology has significant limitations. It can only effectively utilize wind resources within a height range of 0-200 meters above the ground, and this height limitation results in a relatively limited total amount of wind energy that can be captured. Actual operational data shows that the annual equivalent full-load hours of a wind farm are only about 2200 hours, indicating that there is still considerable room for improvement in the wind energy conversion efficiency of existing tower wind power technology.

[0004] Furthermore, existing wind power technology has multifaceted impacts on the power grid system. Regarding system stability, the intermittent and fluctuating nature of wind energy leads to unstable wind power output, posing challenges to the stable operation of the power grid. In terms of power quality, frequent fluctuations in wind power can cause voltage deviations and frequency fluctuations, affecting power quality. Regarding dispatch and management, the unpredictability of wind power increases the difficulty of grid dispatch. Due to the combined effects of these factors, many wind farms experience "wind curtailment," meaning that due to insufficient grid absorption capacity or dispatch restrictions, some wind turbines have to stop generating electricity, further limiting the actual utilization rate of wind energy.

[0005] In power systems, a stable supply of baseload is crucial. Currently, coal-fired power units remain the primary source of baseload. These units offer advantages such as stable operation and high adjustability; after considering peak-shaving factors, their annual equivalent load time can reach 4000-5000 hours, effectively meeting baseload demands. In contrast, existing wind power technology, due to the aforementioned limitations, is unable to shoulder the heavy responsibility of baseload and thus struggles to play a more critical role in the power system.

[0006] Meanwhile, high-altitude wind energy is considered a crucial direction for future wind energy development, possessing enormous potential. High-altitude wind energy resources are abundant and stable; effective development and utilization would significantly improve wind energy efficiency and scale. However, current high-altitude wind energy technology research and development faces numerous technical bottlenecks with its aerostats. Firstly, most existing aerostats are fixed structures, unable to flexibly adjust their attitude to the direction of least resistance based on real-time wind direction changes. This makes it difficult for aerostats to maintain optimal operating conditions in complex and variable wind environments, thus affecting their efficiency in capturing high-altitude wind energy. Secondly, the lift performance of an aerostat is closely related to its size. To ensure sufficient lift to support related equipment and stably levitate at high altitudes, a larger size is often required. However, increased size not only increases manufacturing complexity but also leads to significant increases in material costs and operation and maintenance costs, severely hindering the commercialization and application of high-altitude wind energy technology.

[0027] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0028] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0029] like Figures 1-2 As shown, an airship includes: The floating body 1 has a streamlined design, with a large end 101 and a small end 102 formed at its two ends respectively. A steering part 2 is disposed below the buoy 1, and the buoy 1 can rotate around the steering part 2 as the wind direction changes; The lift adjustment unit 3 is disposed above the buoy 1. The position of the lift adjustment unit 3 changes with the change of wind direction, and always exerts an upward pulling force on the buoy 1.

[0030] The air-supported body 1 adopts a streamlined design, with a large end 101 and a small end 102 at each end. When airflow acts on the air-supported body 1, this streamlined structure allows the airflow to flow more smoothly over the surface of the air-supported body 1, while the streamlined design significantly reduces drag. Specifically, the airflow gradually accelerates and smoothly transitions as it flows through the large end 101, reaching a relatively high and stable velocity at the small end 102, reducing the occurrence of airflow separation.

[0031] The steering section 2 is located below the buoy 1, serving as the rotation center of the buoy 1. When the wind direction changes, the buoy 1 experiences wind forces from different directions, generating a torque. Since the buoy 1 can rotate around the steering section 2, under the influence of this torque, the buoy 1 can automatically adjust its attitude, ensuring that its larger end 101 always faces the wind direction, thus maintaining the buoy 1 in a state of minimum resistance when interacting with the wind. For example, when the wind direction changes from left to right, the wind force on the right will generate a clockwise torque on the buoy 1, causing it to rotate clockwise around the steering section 2 until the larger end 101 is facing the wind direction again.

[0032] The lift adjustment unit 3 is located above the air-supported body 1. It can change its position according to the change of wind direction and always apply an upward pull to the air-supported body 1, thereby obtaining additional lift without increasing the volume of the air-supported body 1 (volume is the cost).

[0033] The lift adjustment unit 3 can adjust the tension on the aerostat 1 in real time according to changes in wind strength and direction, ensuring that the aerostat 1 maintains a stable height and attitude. Simultaneously, the steering unit 2 allows the aerostat 1 to flexibly respond to changes in wind direction, preventing swaying or tilting caused by sudden changes in wind direction. This dual adjustment mechanism enables the aerostat to operate stably in complex and variable wind environments, reducing equipment damage and malfunctions caused by environmental factors, and improving the reliability and service life of the aerostat.

[0034] like Figure 2 As shown, in some embodiments, the lift adjustment part 3 includes a lift adjustment umbrella 301 and a connecting rope 302. The lift adjustment umbrella 301 is connected to the buoy 1 via the connecting rope 302. The lift adjustment part 3 is a cover with a trapezoidal cross-section. The size of the lift adjustment part 3 gradually decreases along the direction away from the buoy 1.

[0035] The lift regulating parachute 301 is connected to the aerostat 1 via a connecting rope 302. The connecting rope 302 serves to transmit lift and stabilize the position of the lift regulating parachute 301. It has a certain strength and elasticity, ensuring a stable and reliable connection between the lift regulating parachute 301 and the aerostat 1 under different wind conditions. Furthermore, the length and angle of the connecting rope 302 can be adjusted according to actual conditions to optimize the working state of the lift regulating parachute 301 and achieve the best lift effect for the aerostat 1.

[0036] The design of the canopy not only enhances lift but also plays a crucial role in the stability of the aerostat 1. It reduces interference from external airflow on the lift regulating chute 301, making its operation more stable. Simultaneously, by dynamically adjusting lift, the aerostat 1 can better cope with sudden changes in wind force, avoiding swaying or tilting caused by insufficient or excessive lift. This stability is essential for the long-term operation of the aerostat in complex environments, reducing equipment failure rates and improving system reliability.

[0037] Because the lift adjustment unit 3 possesses excellent lift adjustment capability and stability, this aerostat can adapt to a wider range of wind conditions. Whether in light or strong wind environments, the lift adjustment unit 3 can adjust the lift according to the actual situation, maintaining the aerostat 1 at a suitable height and attitude. This allows the aerostat to be applied in more regions and scenarios, improving the utilization efficiency of wind energy resources and expanding the application scope of the aerostat. like Figure 2 As shown, in some embodiments, the lift regulating parachute 301 has several jet outlets 303 on its sides and / or top surface. During operation, the wind force is constantly changing. The jet outlets 303 on the lift regulating parachute 301 enable the system to achieve a relative equilibrium under dynamically changing wind conditions. When the wind force increases, the airflow diverted through the jet outlets 303 increases, preventing a sharp increase in lift generated by the lift regulating parachute 301; when the wind force decreases, the jet outlets 303 ensure a certain amount of airflow enters, preventing a rapid decrease in lift. This dynamic equilibrium mechanism allows the aerostat 1 to float more stably in the air, adapting to wind environments of varying intensities.

[0038] The jet outlet 303 significantly improves the stability of the aerostat 1 in the air. In situations with significant wind fluctuations, without the jet outlet 303, the lift generated by the lift regulating parachute 301 would fluctuate wildly with rapid wind changes, causing the aerostat 1 to sway, tilt, or even become uncontrollable. The jet outlet 303, by regulating airflow and pressure differences, allows for relatively smooth changes in lift, reducing the aerostat 1's violent movements and greatly enhancing its stability in complex wind environments. For example, when encountering gusts, the jet outlet 303 can quickly divert excess airflow, preventing the aerostat 1 from rising too high due to a sudden increase in lift; after the gusts subside, it can promptly restore appropriate lift, maintaining the aerostat 1 at a stable altitude.

[0039] like Figure 2 As shown, in some embodiments, the jet outlets 303 are rectangular, and several of the jet outlets 303 are symmetrically distributed around the corner lines of the lift regulating umbrella 301. Because the jet outlets 303 are rectangular and symmetrically distributed around the corner lines, the lift regulating umbrella 301 is more stable when adjusting lift. During wind changes, the symmetrical airflow and pressure difference regulation mechanism can prevent the aerostat 1 from experiencing violent swaying or tilting. For example, when encountering gusts, the airflow enters the umbrella evenly through the jet outlets 303, making the change in lift smoother, and the aerostat 1 can maintain a relatively stable height and attitude. At the same time, the symmetrical distribution of the rectangular jet outlets 303 around the corner lines effectively optimizes the stress situation of the umbrella structure, reducing local stress concentration and lowering the risk of damage to the umbrella structure.

[0040] like Figure 1 As shown, in some embodiments, the steering part 2 includes a bearing 201 and a mounting base 202. The bearing 201 is mounted on the mounting base 202 and is connected to the buoy 1. When the wind direction changes, the buoy 1 can drive the inner ring of the bearing 201 to rotate, which is equivalent to the mounting base 202.

[0041] When the wind direction changes, the aerostat 1 can quickly adjust its orientation by rotating the inner ring of the bearing 201 to adapt to the new wind environment. This adaptive capability enables the aerostat 1 to remain stable under complex and changeable weather conditions, reducing the risk of flight loss of control or deviation from the predetermined position due to wind changes.

[0042] like Figures 1-2As shown, in some embodiments, the small end 102 of the airship 1 is provided with a plurality of steering tail fins 6, which are evenly distributed on the small end 102 of the airship 1. The even distribution of the steering tail fins 6 helps to enhance the stability of the airship 1 during flight. When subjected to external disturbances (such as gusts, airflow fluctuations, etc.), each steering tail fin 6 can work together to counteract the disturbance by adjusting the aerodynamic forces, thus maintaining the balance of the airship 1. For example, when one side is impacted by a strong gust of wind, the steering tail fin 6 on that side will generate a corresponding reaction force to prevent the airship 1 from tilting excessively to one side, thereby improving the airship 1's anti-interference capability and flight stability.

[0043] Example 1 like Figures 1-3 As shown, based on the same inventive concept, this specification provides an airship aerial operation control system, including multiple airships as described above. The multiple airships are arranged in at least two parallel rows. Adjacent turning parts 2 in the same row are connected by a first fixing rope 10. The turning parts 2 are connected to two adjacent turning parts 2 in different rows by two sets of second fixing ropes 11.

[0044] In practice, the steering sections 2 of adjacent aerostats in the same row are connected by a first fixing rope 10. When an aerostat is affected by wind and its attitude changes or its position shifts, the first fixing rope 10 will restrain and pull it. For example, if an aerostat tilts to one side under the action of wind, the pull of the first fixing rope 10 will pull the aerostat back to a relatively stable position. At the same time, this pull will also be transmitted to adjacent aerostats, so that the aerostats in the same row maintain a relatively consistent attitude and position in the lateral direction and work together to cope with changes in wind force.

[0045] The steering unit 2 is connected to two adjacent steering units 2 in different rows via two sets of second fixed ropes 11. This connection method establishes communication between airships in different rows. When a device in one row is impacted by wind, its motion is transmitted to the devices in the adjacent rows via the second fixed ropes 11. For example, if a device in the front row swings forward under strong winds, the second fixed ropes 11 will transmit this swinging force to the adjacent devices in the rear row, allowing the rear devices to make corresponding adjustments in advance, such as adjusting the attitude of the airship or the position of the flight power device 7, to better adapt to changes in wind force and maintain the stability of the entire system.

[0046] Through the mesh-like connection structure formed by the first fixed rope 10 and the second fixed rope 11, the entire airship's aerial operation control system forms an organic whole. When abnormal changes occur in the wind force in a local area, these changes are quickly transmitted to the entire system via the fixed ropes. Each device automatically adjusts its operating state based on the received force and motion information, achieving coordinated and stable operation. For example, in windy weather, the devices in the system will work together to disperse the impact force of the wind through the interaction of the fixed ropes, preventing any device from being damaged due to excessive force and ensuring that the entire system can continuously and stably generate electricity.

[0047] Example 2 like Figures 1-2 and Figure 4 As shown, based on the same inventive concept, this specification provides an airship aerial operation control system, including multiple airships as described above. The multiple airships are distributed in a polygonal pattern. Adjacent turning parts 2 are connected by a third fixing rope 12. Each of the multiple turning parts 2 is connected to a fourth fixing rope 13, and the multiple fourth fixing ropes 13 have at least one common connection point.

[0048] In practice, the airborne operation control system of this aerostat consists of multiple aerostats arranged in a polygonal layout. Initially, each aerostat is fixed to a specific position by tethering ropes 4, and the steering section 2 is in a relatively stable state. Adjacent steering sections 2 are connected by third fixing ropes 12, forming a polygonal frame structure. Simultaneously, fourth fixing ropes 13 connected to multiple steering sections 2 converge at at least one common connection point. This common connection point can be a fixed anchor point on the ground or a stable structure at a specific location in the air, providing additional stability support and constraints for the entire system.

[0049] Adjacent aerostats are interconnected via a third anchoring rope 12. When one device experiences a change in attitude or position due to wind, the third anchoring rope 12 immediately generates a change in tension or strain. For example, if an aerostat tilts to one side under strong winds, the third anchoring rope 12 will pull it in the opposite direction. Simultaneously, this tension is transmitted to adjacent devices, causing them to adjust accordingly to maintain the stability of the entire polygonal structure. This lateral coordination quickly balances the effects of localized wind changes, preventing damage to individual devices due to excessive stress.

[0050] The fourth fixed ropes 13 connected to multiple steering units 2 converge at a common connection point, forming a longitudinal connection system from the device group to the fixed point. When the system is subjected to large-scale wind impact or complex airflow, the common connection point can provide a stable reference point. Each device transmits the force and motion information it receives to the common connection point through the fourth fixed ropes 13, and the common connection point then coordinates and balances the entire system based on this information.

[0051] Example 3 like Figures 1-2 and Figure 5 As shown, based on the same inventive concept, this specification provides an airship aerial operation control system, including multiple airships as described above. The multiple airships are distributed in a polygonal pattern. Adjacent turning parts 2 are connected by a fifth fixing rope 14. Each of the multiple turning parts 2 is connected to a sixth fixing rope 15. The multiple sixth fixing ropes 15 are interconnected to form a regular polygonal structure 16.

[0052] In practice, when an aerostat tilts or moves to one side due to wind, adjacent aerostats exert opposing tensions via the fifth fixed rope 14. For example, if aerostat A shifts to the right under wind, the adjacent aerostat B will pull aerostat A to the left via the fifth fixed rope 14, while aerostat A will also pull aerostat B to the right via the fifth fixed rope 14. However, aerostat A experiences a greater tension, thus returning it to a relatively stable position. This lateral force balancing action can quickly suppress unstable movement of local devices and prevent damage to individual devices due to uneven force distribution.

[0053] The regular polygonal structure 16 formed by the sixth fixing rope 15 provides a stable geometric framework for the entire system. When the system is subjected to large-scale wind impacts or complex airflow, the regular polygonal structure 16 can evenly distribute the stress generated by the wind, preventing stress concentration on one or a few devices. For example, in strong winds, the force of the wind on the system is transmitted through the sixth fixing rope 15 to each vertex (i.e., each turning part 2) of the entire regular polygonal structure 16, so that each device bears a portion of the stress, thereby enhancing the overall wind resistance of the system.

[0054] like Figures 1-5 As shown, based on the same inventive concept, this specification provides a wind power generation device, including a tether rope 4, a pulley block 5, a transmission rope 8, a flight power device 7, and an airship air operation control system as described in any of the above. The two ends of the tether rope 4 are respectively connected to the steering part 2 and the fixed base structure. The pulley block 5 is installed on the tether rope 4. The transmission rope 8 passes around the pulley block 5. The flight power device 7 is fixed on the transmission rope 8. The flight power-generating device 7 is configured to move along the tethering rope 4 when subjected to wind force, thereby driving the transmission rope 8 to move and perform work on the transmission rope 8.

[0055] In practice, the aerostat can ascend to higher altitudes where wind resources are typically more abundant and stable. Compared to traditional ground-based wind power generation devices, this device can fully utilize high-altitude wind energy, avoiding obstruction and interference from ground obstacles, and improving wind energy capture efficiency. Driven by the aerostat, the flying power unit 7 can more effectively capture energy under wind power and convert it into the motion of the drive rope 8, providing a sufficient energy source for subsequent power generation.

[0056] Driven by wind, the flying power device 7 moves along the direction of the tethering rope 4. As it moves, it drives the transmission rope 8, which is fixedly connected to it, to move as well. Because the transmission rope 8 passes through the pulley system 5, the rolling friction of the pulley system 5 allows the transmission rope 8 to move relatively smoothly. When the flying power device 7 moves in one direction, the transmission rope 8, guided by the pulley system 5, will move accordingly on the other side. The flying power device 7 driving the transmission rope 8 is essentially doing work on it. From an energy conversion perspective, the wind gives the flying power device 7 kinetic energy, which it then transfers to the transmission rope 8, causing it to move. The movement of the transmission rope 8 can be further connected to other energy conversion devices 9, such as a generator. When the transmission rope 8 drives the generator rotor to rotate, mechanical energy is converted into electrical energy, realizing the wind power generation process. For example, in some practical applications, the transmission rope 8 can be connected to a gear transmission system, where the meshing of the gears converts the linear motion of the transmission rope 8 into rotational motion, thereby driving the generator to generate electricity. Throughout the process, the flight power-generating device 7, as a component for capturing and initially converting wind energy, transmits the energy to the subsequent power generation equipment via the transmission rope 8.

[0057] The overall structure of this wind power generation device is relatively simple, mainly composed of several key components such as tethering rope 4, pulley system 5, transmission rope 8, flight power generation device 7, and aerostat. The connections and transmission methods between these components are clear and straightforward, reducing potential malfunctions and maintenance costs associated with complex mechanical structures. The use of pulley system 5 reduces frictional resistance during transmission, improves energy transfer efficiency, and enhances the reliability of the device. Furthermore, the aerostat is designed for stability and durability, enabling long-term operation under harsh weather conditions and ensuring the stable operation of the entire power generation device. Because the aerostat is suspended in the air, this wind power generation device does not require a large amount of ground space, reducing damage to the ground ecosystem and interference with human activities. Compared to traditional ground-based wind farms, it can be deployed in various terrain conditions, including urban areas, farmland, and mountainous regions, offering a wider range of applications.
