Description

Technical Field

[0001] This invention relates to the field of flying wind energy, and in particular to a flying wind turbine generator set, a flying power generation device, a flight control device, a flight connection assembly, and a flight control method. Background Technology

[0002] Energy is a crucial material foundation for economic and social development, and also the primary source of carbon emissions. To address global warming caused by carbon emissions, the United Nations General Assembly adopted the United Nations Framework Convention on Climate Change in 1992. Wind energy, as a renewable and clean energy source, has seen development in recent years. However, existing tower wind power technology can only utilize wind resources at a height of 0-200 meters above ground, resulting in an annual equivalent full-load operating time of only about 2200 hours for wind farms. Due to its impact on grid system stability, power quality, and dispatch management, many wind farms experience curtailment, further limiting wind energy utilization. Currently, coal-fired power units still bear the base load, with an annual equivalent load time of 4000-5000 hours after peak shaving considerations. Existing wind power technology is not yet capable of handling the heavy burden of base load.

[0003] In addition, the construction of existing tower wind farms has a significant impact on the ecological environment, and the wind turbines generate a lot of noise. Moreover, wind farms are often far from electricity consumption areas (such as coastal cities), requiring long-distance (e.g., thousands of kilometers) power transmission.

[0004] Studies have shown that the relationship between wind energy and wind speed is as shown in the following formula (1): (1) in: E: indicates wind energy (unit: joule or watt-hour); ρ: represents air density (unit: kg / m³); A: Represents the swept area of ​​the wind turbine or the cross-sectional area through which the airflow passes (unit: square meters); V: indicates wind speed (unit: meters per second).

[0005] As can be seen from the above formula, wind energy is directly proportional to the cube of wind speed. For example, when the wind speed doubles, the wind energy will increase eightfold.

[0006] Due to the influence of the Earth's surface shape, especially in urban areas, the wind speed below 200 meters is much lower than the wind speed above 200 meters due to the obstruction effect of buildings. Therefore, ground wind energy is much lower than high-altitude wind energy.

[0007] The wind energy density and total amount stored in the air above 300 meters are high, and the higher the altitude, the stronger and more stable the wind. At an altitude of 500 meters, the available wind energy density is twice that at ground level 95% of the time; at an altitude of 1000 meters, the wind energy density is about five times that at ground level; and at an altitude of 10,000 meters, the maximum wind energy density is about 100 times that at ground level. The wind energy density of the upper-level jet stream in the Jiangsu, Zhejiang, and Shandong regions of China is about 30 times that of the wind energy density at ground level.

[0008] The duration of wind resources in the 300-2000 meter airspace is twice that of wind resources in the 0-200 meter airspace. The annual equivalent full-load hours of new wind power technologies utilizing wind resources in the 300-2000 meter airspace can reach more than 4400 hours, or even more than 6500 hours, which can be used as a base load.

[0009] To utilize wind energy at greater altitudes, existing wind power technologies require taller structures and more wind-resistant, reliable ground foundations. A 5-megawatt wind turbine weighs hundreds of tons, demanding high foundation strength; a 5-megawatt offshore wind power platform weighs thousands of tons. Significantly increasing the height of existing tower wind turbines faces problems such as soaring costs, increased construction difficulty, and exacerbated environmental impacts.

[0010] Furthermore, wind turbines need to avoid areas swept by typhoons / hurricanes, making them unsuitable for deployment in coastal cities. Coastal cities, on the other hand, possess abundant marine and high-altitude resources.

[0011] Both domestic and international research and development in the field of high-altitude wind energy has been carried out, but an effective technical solution has not yet been formed, especially a land-based wind energy technology that can continuously utilize high-altitude wind energy to do work (such as power generation) under any wind direction.

[0012] Therefore, there is an urgent need to develop a land-based wind energy technology that can continuously utilize high-altitude wind energy to perform work (such as generating electricity) under any wind direction. Summary of the Invention

[0041] It should also be noted that, in order to avoid obscuring the present invention by including unnecessary details, only the structures and / or processing steps closely related to the technical solution of the present invention are shown in the accompanying drawings, while other details that are not closely related to the technical solution of the present invention are omitted.

[0042] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, step, or component, but does not exclude the presence or addition of one or more other features, elements, steps, or components.

[0043] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0044] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0045] Figure 1 This is a schematic diagram of a flying wind turbine generator set 1000 according to an embodiment of the present invention. The flying wind turbine generator set 1000 can continuously convert wind energy in the air into mechanical work through unpowered flight technology and transmit it to the ground / fixed foundation structure.

[0046] like Figure 1 As shown, the flying wind turbine equipment 1000 includes a buoyancy device 1100 and a first mooring cable 1200-1 and a second mooring cable 1200-2. The buoyancy device 1100 can be a device capable of providing buoyancy in the air, such as a helium balloon, to lift the flying wind turbine equipment 1000 to a predetermined altitude, such as 500 meters or higher. The buoyancy device 1100 is connected to the ground or other fixed foundation structure 2000 (e.g., roof, offshore floating platform, etc.) via the first mooring cable 1200-1 and the second mooring cable 1200-2.

[0047] The first mooring cable 1200-1 and the second mooring cable 1200-2 can be made of ropes of the same material and can be set symmetrically or asymmetrically (with different inclination angles relative to the ground. For example, the mooring cable 1200 closer to the windward side has a smaller inclination angle relative to the ground, while the mooring cable 1200 farther from the windward side has a larger inclination angle relative to the ground).

[0048] Figure 1 The diagram shows the upper ends of the first mooring cable 1200-1 and the second mooring cable 1200-2 intersecting at a point on the levitation device 1100. This is for illustrative purposes only. In actual implementation, the upper ends of the two cables can be connected to the levitation device 1100 at a certain distance apart.

[0049] Figure 1 The diagram shows that there is one first mooring cable 1200-1 and one second mooring cable 1200-2, which is only for illustration. In actual implementation, there can be multiple first mooring cables 1200-1 and second mooring cables 1200-2.

[0050] Figure 1The diagram shows that the first mooring cable 1200-1 and the second mooring cable 1200-2 are directly connected to the ground or other fixed foundation structure 2000. In a specific implementation, the first mooring cable 1200-1 and the second mooring cable 1200-2 can also be connected to a ring-shaped slide rail set on the ground or other fixed foundation structure 2000 via rollers or the like, so that the lower ends of the first mooring cable 1200-1 and the second mooring cable 1200-2 can roll along the ring-shaped slide rail, thereby adjusting the orientation of the entire flying wind turbine equipment 1000. For example, preferably, the plane formed by the first mooring cable 1200-1 and the second mooring cable 1200-2 can be substantially parallel to the wind direction plane to improve the overall working efficiency of the flying wind turbine equipment 1000. Alternatively, when the wind intensity exceeds a predetermined value, appropriate adjustments can be made so that the plane formed by the first mooring cable 1200-1 and the second mooring cable 1200-2 forms an angle with the wind direction plane, thereby reducing the overall work efficiency of the flying wind turbine equipment 1000.

[0051] The flying wind turbine equipment 1000 also includes a transmission cable 1300 and a first flight power device 1400-1 and a second flight power device 1400-2 connected to the transmission cable 1300.

[0052] Figure 1 The image shows a flight power device 1400 on each of the left and right sides. This is just an example. In actual implementation, multiple flight power devices 1400 can be set on the left and right sides at equal or unequal intervals.

[0053] A first upper pulley 1500-1 and a first lower pulley 1500-2 are provided on the first mooring cable 1200-1, and a second upper pulley 1500-3 and a second lower pulley 1500-4 are provided on the second mooring cable 1200-2. A transmission cable 1300 surrounds the first upper pulley 1500-1, the first lower pulley 1500-2, the second upper pulley 1500-3, and the second lower pulley 1500-4, and is connected to a ground-based working device 3000. The ground-based working device 3000 may be, for example, a generator.

[0054] The flight power device 1400 is fixedly connected to the transmission cable 1300 and movable relative to the tether cable 1200. By adjusting the attitude of its flight components, it can be driven by the wind to fly up and down alternately, thereby driving the transmission cable 1300 to reciprocate. The transmission cable 1300 further drives the ground power device 3000 to perform work.

[0055] The ground-based power-operating device 3000 may include a power ring 3100 and an output unit (e.g., a generator) connected to the power ring 3100. The power ring 3100 may be a rotating structure, for example. For instance, a transmission cable 1300 may be connected to the power ring 3100 of the ground-based power-operating device 3000 to convert the linear reciprocating motion of the transmission cable 1300 into the rotational motion of the power ring 3100, which further drives the output unit of the ground-based power-operating device 3000 to generate output. For example, the transmission cable 1300 may be connected to the power ring 3100 by winding or by other mechanisms (e.g., a crank mechanism) to convert the reciprocating motion of the transmission cable 1300 into the rotational motion of the power ring 3100.

[0056] Figure 2A and 2B The example illustrates the principle by which the flight power device 1400 changes the direction of wind-driven flight by adjusting the attitude of its flight components, thereby achieving alternating up-and-down flight.

[0057] like Figure 2A As shown, in response to the incoming wind 4000, the first flight power device 1400-1 adjusts the attitude of its flight components to tilt upwards. The overall force exerted by the incoming wind 4000 on the flight components is shown in Figure F1. The component F2 of this force F1 along the direction of the transmission cable 1300 pushes the first flight power device 1400-1 to fly upwards along the direction of the transmission cable 1300. Simultaneously, the second flight power device 1400-2 adjusts the attitude of its flight components to tilt downwards. The overall force exerted by the incoming wind 4000 on the flight components is shown in Figure F3. The component F4 of this force F3 along the direction of the transmission cable 1300 pushes the second flight power device 1400-2 to fly downwards along the direction of the transmission cable 1300. Thus, the upward flight of the first flight power device 1400-1 and the downward flight of the second flight power device 1400-2 together drive the transmission cable 1300 to move clockwise.

[0058] When the first flight power device 1400-1 reaches the upper limit (or enters a predetermined distance range of the upper limit, such as 5 meters or 10 meters) and the second flight power device 1400-2 reaches the lower limit (or enters a predetermined distance range of the lower limit, such as 5 meters or 10 meters), they respectively adjust the attitude of their flight components. Figure 2BAs shown, the first flight power device 1400-1 adjusts the attitude of its flight components to tilt downwards. The force exerted by the incoming wind 4000 on the flight components is shown in Figure F5. The component F6 of this force F5 along the direction of the transmission cable 1300 pushes the first flight power device 1400-1 downwards along the direction of the transmission cable 1300. Simultaneously, the second flight power device 1400-2 adjusts the attitude of its flight components to tilt upwards. The force exerted by the incoming wind 4000 on the flight components is shown in Figure F7. The component F8 of this force F7 along the direction of the transmission cable 1300 pushes the second flight power device 1400-2 upwards along the direction of the transmission cable 1300. Thus, the downward flight of the first flight power device 1400-1 and the upward flight of the second flight power device 1400-2 cause the transmission cable 1300 to move counterclockwise.

[0059] When the first flight power unit 1400-1 reaches the lower limit (or enters a predetermined distance range of the lower limit, such as 5 meters or 10 meters) and the second flight power unit 1400-2 reaches the upper limit (or enters a predetermined distance range of the upper limit, such as 5 meters or 10 meters), each adjusts the attitude of its flight components again, changing its flight direction. This cycle repeats, driving the transmission cable 1300 to continuously reciprocate, thereby driving the ground power unit 3000 to continuously output power.

[0060] The above reference Figure 1 and Figure 2A , 2B The structure, configuration, and reciprocating flight principle of the flying wind turbine generator set 1000 are described. The flying wind turbine generator set 1000 according to this invention is not limited to... Figure 1 The structure and composition shown are acceptable as long as they possess the necessary basic structure and can be implemented. Figure 2A , 2B Any form of the reciprocating flight principle shown falls within the protection scope of this invention.

[0061] For example, Figures 3 to 8 Several variations of the 1000-type flying wind turbine unit are shown.

[0062] Figure 3 This example illustrates the first variant of the 1000-unit flying wind turbine. (And...) Figure 1 Compared to the structure shown, the middle section of the mooring cable 1200 is omitted, retaining only the connection structures 1200-3 and 1200-4 between the first upper pulley 1500-1, the second upper pulley 1500-3 and the levitation device 1100, and the connection structures 1200-1 and 1200-2 between the first lower pulley 1500-2, the second lower pulley 1500-4 and the ground or fixed foundation structure 2000. According to the structure of the first variant, the flying wind turbine equipment 1000 can achieve continuous power output while significantly reducing its weight.

[0063] Figure 4 This example illustrates a second variant of the 1000-unit flying wind turbine. (Compared to...) Figure 3 Compared to the structure shown, one upper pulley is reduced, and the connection structure between the upper pulley and the levitation device 1100 is also simpler.

[0064] Figure 5 This example illustrates the third variant of the 1000-unit flying wind turbine. (And...) Figure 1 Compared to the structure shown, only one mooring cable 1200 is retained, one upper and one lower pulley are reduced, and the size of the lower pulley 1500-2 is increased. It is combined with the working ring 3100 of the ground working device 3000 into one, which can be connected to the output of the ground working device 3000. The structure of the flying wind turbine equipment 1000 according to the third variant is greatly simplified, and the overall weight is significantly reduced.

[0065] Figure 6 This example illustrates the fourth variant of the 1000-unit flying wind turbine. (And...) Figure 5 Compared to the structure shown, the two upper pulleys 1500-1 and 1500-3 are retained. The distance between the two upper pulleys 1500-1 and 1500-3 can be appropriately set to avoid interference between the flight power device 1400 and the transmission cable 1300, which helps to increase the flight stroke of the flight power device 1400.

[0066] Figure 7 This example illustrates the fifth variant of the 1000-unit flying wind turbine. (And...) Figure 5 Compared to the structure shown, the mooring cable 1200 is omitted, and only the connection structure 1200-1 between the upper pulley 1500-1 and the buoyancy device 1100 and the connection structure 1200-2 between the lower pulley 1500-2 (work ring 3100) and the ground or fixed foundation structure 2000 are retained. Compared to the third variant, the structure of the flying wind turbine equipment 1000 according to the fourth variant is further simplified, the overall weight is further reduced, and the equipment deployment is easier.

[0067] Figure 8 This example illustrates the sixth variant of the 1000-unit flying wind turbine. (And...) Figure 7 Compared to the structure shown, the two upper pulleys 1500-1 and 1500-3 are retained. The distance between the two upper pulleys 1500-1 and 1500-3 can be appropriately set to avoid interference between the flight power device 1400 and the transmission cable 1300, which helps to increase the flight stroke of the flight power device 1400.

[0068] also, Figure 1Only one ground-based working device 3000 is shown in the diagram. In a practical implementation, two ground-based working devices 3000 can be provided, with the left and right transmission cables 1300 each connected to one ground-based working device 3000, as shown below. Figure 9 As shown. Figure 3 and Figure 4 The first and second variations shown also apply here.

[0069] In addition, as mentioned above Figure 1 As described in the specifications of the flying wind turbine unit 1000, the orientation of the flying wind turbine unit 1000 can be adjusted by setting a suitable rolling mechanism. This also applies to... Figure 3 , 4 The first and second variations are shown. For Figure 5-8 In the third to sixth variations shown, a rotatable platform can be installed on the ground or on a fixed foundation structure 2000, and the lower end of the flying wind turbine unit 1000 can be connected to the rotatable platform.

[0070] The following reference Figures 10 to 13 The composition of the flight power-generating device 1400 is described in detail to further understand the principle that the flight wind turbine equipment 1000 can continuously perform reciprocating work.

[0071] Figure 10 and Figure 11 These are, respectively, perspective and planar schematic diagrams illustrating the structure of a flight power device 1400 according to an embodiment of the present invention.

[0072] like Figure 10 and Figure 11 As shown, the flight power device 1400 includes a flight connection assembly 1410, a flight control device 1420, and a flight component 1430.

[0073] The flight connection assembly 1410 has an overall inner and outer double-layer structure. The outer and inner layers can be connected, for example, via bearings, allowing the outer layer to rotate relative to the inner layer. See below for further details. Figures 12 to 14 The structure of the flight connection assembly 1410 is described in detail.

[0074] The flight control unit 1420 is fixedly mounted to the flight connection assembly 1410. The flight connection assembly 1410 is fixedly connected to the transmission cable 1300, and allows the tether cable 1200 to pass through it and be movable relative to the tether cable 1200.

[0075] Flight component 1430 can be, for example, as... Figure 10The illustrated hollow truncated pyramid structure of the paraglider has a small bottom and a large opening. It is connected to a flight control device 1420 via multiple (e.g., four) flexible parachute cables 1431. The flight control device 1420 can adjust the attitude of the flight component 1430 by adjusting the length of the parachute cables 1431, changing its angle of attack and frontal area, thereby altering the wind force it receives and causing it to fly upwards or downwards along the direction of the tether cable 1200 or the drive cable 1300. The flight component 1430 drives the flight connection assembly 1410 via the parachute cables 1431, which in turn drives the drive cable 1300, which is fixedly connected to the flight connection assembly 1410. In this way, the drive cable 1300 converts wind energy in the air into mechanical work and transmits it to the ground-based work-generating device 3000.

[0076] It should be noted that the flight component 1430 can also be other shapes, such as sail-shaped or wing-shaped, and it can be connected to the flight control device 1420 through a rigid or elastic and / or telescopic rod structure. The flight control device 1420 can change the attitude of the flight component 1430 by adjusting the direction of the rigid or elastic rod structure, thereby changing its angle of attack and frontal area, thus changing the wind force it receives, and causing it to fly upward or downward along the mooring cable 1200.

[0077] Figure 12 This is a perspective view showing the main structure of a flight connection assembly 1410 according to an embodiment of the present invention. Figure 13 This is a cross-sectional view along the "AA" direction. Figure 14 It is a cross-sectional view along the "BB" direction.

[0078] The flight connection assembly 1410 is a key component of the flight power device 1400, used to realize the connection and relative movement between multiple components, and to realize the "internal-external" electrical connection function.

[0079] As shown in the figure, the flight connection assembly 1410 can generally include an inner structure 1411 and an outer structure 1412. The inner structure 1411 and the outer structure 1412 can be cylindrical or partially cylindrical. For example, the inner structure 1411 can be cylindrical at both ends and connected in the middle by multiple columns to facilitate the assembly of various internal components. The inner structure 1411 and the outer structure 1412 are connected at both ends by bearings 1413-1 and 1413-2. In this way, the outer structure 1412 can rotate relative to the inner structure 1411.

[0080] The drive cable 1300 is fixedly connected to both ends of the inner structure 1411. The tether cable 1200 can pass through the inner structure 1411. In this way, the flight connection assembly 1410 can be displaced together with the drive cable 1300 and can move relative to the tether cable 1200.

[0081] To supply power to the flight control unit 1420, the flight connection assembly 1410 also includes first and second "inner-outer" conductive connection structures 1414-1 and 1414-2, extending from the inner structure 1411 to the outer structure 1412. The first and second "inner-outer" conductive connection structures 1414-1 and 1414-2 have the same structure and are used to connect positive and negative electricity, respectively.

[0082] Figure 14 This is a schematic diagram illustrating an "inner-outer" conductive connection structure 1414 according to an embodiment of the present invention.

[0083] As shown in the figure, the "inner-outer" conductive connection structure 1414 may include an inner electrode 14141, an insulating ring 14142, a conductive ring 14143, a brush 14144, and an outer electrode 14145. The inner electrode 14141 passes through a through-hole in the inner layer structure 1411 and the insulating ring 14142, making electrical contact with the conductive ring 14143, and is wired to a power supply structure connected to the inner layer structure 1411 (not shown). An insulating layer is provided between the inner electrode 14141 and the through-hole in the inner layer structure 1411. The insulating ring 14142 surrounds the inner layer structure 1411, providing electrical isolation between the conductive ring 14143 and the inner layer structure 1411. The conductive ring 14143 surrounds the insulating ring 14142. The brush 14144 includes a spring and a smooth, wear-resistant conductor (e.g., graphite), which makes tight electrical contact with the conductive ring 14143 under spring pressure. The external electrode 14145 is electrically connected to the brush 14144 and passes through a through hole in the outer layer structure 1412. An insulating layer is provided between the external electrode 14145 and the through hole in the outer layer structure 1412.

[0084] In this way, with the outer structure 1412 rotatable relative to the inner structure 1411, a stable electrical connection is achieved from the inner structure 1411 to the outer structure 1412, thereby providing power to the flight control device 1420 mounted on the outer structure 1412.

[0085] The following reference Figures 15 to 17 The power supply to the flight power unit 1400 is explained via a contact cable arranged parallel to the mooring cable 1200.

[0086] For example Figure 1 The illustrated embodiments, such as Figure 15 As shown, positive and negative contact cables 1600-1 and 1600-2 can be arranged parallel to the mooring cable 1200. The positive and negative contact cables 1600-1 and 1600-2 can be connected to the mooring cable 1200, for example, through a "Y"-shaped insulating bracket 1700.

[0087] Figure 16The diagram illustrates how power is drawn via the pantograph 1800 along a direction perpendicular to the cable. A Y-shaped pantograph 1800 (installation relationship not shown) is installed within the inner structure 1411 of the flight connection assembly 1410. The pantograph 1800 consists of positive and negative receiving sections 1810 and 1820, electrically isolated from each other by an insulator 1830, and electrically connected to the first inner electrode 14141-1 and the second inner electrode 14141-2 respectively disposed on the inner structure 1411. For clarity, gaps exist between the positive and negative receiving sections 1810 and 1820 and the intermediate insulator 1830; in reality, the three are tightly joined together to form a single unit. The pantograph 1800 presses the positive and negative contact cables 1600-1 and 1600-2 under the action of a spring (not shown). For example, the positive and negative contact cables 1600-1 and 1600-2 can be powered by a DC power source installed on the ground or on the fixed foundation structure 2000, or by a DC power source (e.g., a photovoltaic cell) installed on the aerostat 1100. This achieves power supply to the flight power unit 1400, and particularly to the flight control unit 1420.

[0088] The connection between the contact cable 1600 and the mooring rope 1200 is not limited to the methods described above. For example, as... Figure 17 As shown, the positive and negative contact cables 1600 can be arranged close to and parallel to the mooring cable 1200, which serves as an insulator, via retaining rings. Accordingly, the "Y"-shaped pantograph 1800 can be changed to a "U"-shaped shape.

[0089] The tether cable 1200 can also be made of a conductor material. For example, in Figure 1 Two mooring cables 1200 can be installed on each side, and these two mooring cables 1200 can be separated by an insulating bracket. In this way, the mooring cables 1200 can also serve as contact cables 1600.

[0090] It can also be powered by a contact cable arranged in parallel with the transmission cable 1300.

[0091] For example, refer to Figure 17In the structure shown, the positive and negative cables 1600-1 and 1600-2 can be arranged parallel to the transmission cable 1300 (which serves as an insulator) via retainers, and are fixedly connected together with the transmission cable 1300 to the inner structure 1411 of the flight connection assembly 1410. They are also electrically connected to the positive and negative inner electrodes 14141-1 and 14141-2 via wires, respectively. On the ground or other fixed base structure 2000 side or the aerostat 1100 side, a U-shaped power supply pantograph with the same structure as the aforementioned U-shaped pantograph 1800 can be installed to make electrical contact with the contact cable 1600, thereby supplying the DC power from the ground or other fixed base structure 2000 or the aerostat 1100 to the contact cable 1600, and then to the flight power-operating device 1400, especially the flight control device 1420. For clarity of illustration, there are gaps between the positive and negative power receiving parts 1810 and 1820 and the intermediate insulator 1830. In reality, the three are tightly joined together to form a single integral component.

[0092] The transmission cable 1300 can also be made of a conductor material. In this case, two transmission cables 1300 can be arranged in parallel to serve as contact cables 1600. Accordingly, materials such as... Figure 18 The diagram shows a double-grooved pulley 1500 separated by an insulator. The double-grooved pulley 1500 includes a left half 1510 and a right half 1520 made of conductors, and an insulator 1530 electrically isolating the two. For clarity, gaps exist between the left half 1510, 1520 and the intermediate insulator 1530; in reality, the three are tightly joined together to form a single unit. Two drive cables 1300 are wound into the grooves of the left half 1510 and the right half 1520, respectively, and are fixedly connected to the inner structure 1411 of the flight connection assembly 1410, and electrically connected to the positive and negative inner electrodes 14141-1 and 14141-2, respectively, via wires. The left half 1510 and the right half 1520 of the double-grooved pulley 1500 are electrically connected to the positive and negative terminals of a DC power supply located on the ground or other fixed foundation structure 2000 or the aerostat 1100. This allows for the supply of power to the flight power unit 1400, and especially the flight control unit 1420.

[0093] Below, refer to Figure 19 The configuration and function of a flight control device 1420 according to an embodiment of the present invention will be described.

[0094] like Figure 19 As shown, the flight control device 1420 may include a control unit 1421, a position / travel detection unit 1422, and multiple attitude adjustment mechanisms 1425-1, 1425-2, 1425-3, and 1425-4.

[0095] The position / travel detection unit 1422 can detect the position and / or distance traveled of the flight work device 1400 relative to a base point (e.g., upper or lower limit), or the distance relative to the base point.

[0096] The control unit 1421 can compare the position / travel or distance data detected by the position / travel detection unit 1422 with a preset threshold. When it is determined that the flight power device 1400 is approaching the upper or lower limit (for example, the distance to the upper or lower limit is less than 5 meters or 10 meters), the control unit 1421 generates an attitude adjustment signal and sends the attitude adjustment signal to the attitude adjustment mechanism 1425.

[0097] The attitude adjustment mechanism 1425 changes the attitude (angle of attack, frontal area) of the flight component 1430 based on the received attitude adjustment signal, for example, by adjusting the length of the parachute lines 1431, thereby changing its flight speed. This ensures that when the upper or lower limit is reached, the speed of the flight power device 1400 is reduced to approximately zero, and the attitude of the flight component 1430 is further adjusted to reverse its flight direction. For example, the attitude adjustment mechanism 1425 can be a digital motor.

[0098] Optionally, the flight control device 1420 may further include a flight speed detection unit 1423. The flight speed detection unit 1423 can detect the flight speed of the flight power device 1400. For example, when the control unit 1421 determines that attitude adjustment is needed based on the detected position / travel data, it can instruct the flight speed detection unit 1423 to detect the real-time flight speed of the flight power device 1400 and generate an attitude adjustment signal based on the detected real-time flight speed to more smoothly control the flight of the flight power device 1400.

[0099] Optionally, the flight control unit 1420 may also include a wind force / direction detection unit 1424. The wind force / direction detection unit 1424 can detect wind force and / or wind direction for the control unit 1421 to generate attitude adjustment signal reference.

[0100] Although not shown in the figure, the flight control unit 1420 may also include a wireless communication unit for communication with each other or with a ground control center. For example, the wind force / direction detection unit 1424 may not be located in the flight control unit 1420. The flight control unit 1420 can receive wind force and / or wind direction data detected by wind force / direction detection devices installed on the ground or other fixed infrastructure 2000 or aerostat 1100 via the wireless communication unit and provide it to the control unit 1421. The functions of the position / travel detection unit 1422 and the flight speed detection unit 1423 can also be implemented at other locations on the flying wind turbine equipment 1000, transmitting data via the wireless communication unit of the flight control unit 1420.

[0101] Below, refer to Figure 20 The flowchart shown describes a flight control method 5000 executed by the flight control device 1420 in a flying wind turbine 1000 according to an embodiment of the present invention.

[0102] As shown in the figure, flight control method 5000 includes: Step S5100: Receive position / travel data of the flight power device (1400) detected by the position / travel detection unit 1422; Step S5200: Based on the received position / travel data and a preset threshold, determine whether the flight working device 1400 has entered a predetermined range from the upper or lower limit (e.g., 5 meters or 10 meters from the upper or lower limit), i.e., whether the flight working device 1400 needs to be adjusted. If the determination result is "yes", proceed to step S5300; if the determination result is "no", return to step S5100. Step S5300: Generate an attitude adjustment signal and send the generated attitude adjustment signal to the attitude adjustment mechanism 1425 so that the attitude adjustment mechanism 1425 adjusts the flight attitude of the flight component 1430 (e.g., angle of attack, frontal area, etc.) based on the received attitude adjustment signal, thereby changing the flight speed of the flight power device 1400.

[0103] Optionally, the flight control method 5000 may also include the following steps: S5400: Command flight speed detection unit 1423 detects the flight speed of flight work unit 1400 and receives the detected flight speed data; and / or S5500: Commands the wind force / direction detection unit 1424 to detect wind force and / or wind direction and receives the detected wind force and / or wind direction data.

[0104] Thus, in step S5300, the flight speed data received in step S5400 and the wind force and / or wind direction data received in step S5500 can be further referenced to generate an attitude adjustment signal, so as to perform more stable control on the flight power device 1400. The control unit 1421 can also generate an attitude adjustment signal independently based on the received flight speed data and wind force and / or wind direction data.

[0105] This application also includes program code for implementing the above-described flight control method 5000 and a computer storage medium containing the program code.
