Description

Technical Field

[0001] This specification relates to the field of wind power generation technology, specifically to a power generation device accompanying a flying wind turbine and the flying wind turbine itself. Background Technology

[0002] High-altitude wind energy is considered an important direction for future wind energy development, possessing enormous potential. High-altitude wind energy resources are abundant and stable; effective development and utilization will greatly improve the efficiency and scale of wind energy utilization.

[0003] Chinese Patent Publication No. CN118757313B discloses a flying saucer-shaped wind power generation system that enables continuous power generation at mid-to-high altitudes, such as... Figures 1-3 As shown in the figure, 1-Helium balloon; 3-Kite flying saucer assembly; 4-Parachute cable; 5-Power generation facility; 11-Main winding cable; 12-Fixed pulley; 13-Main winding cable winch; 14-Slip ring; 31-Powering umbrella; 41-Limit block; 42-Swivel tray; 43-Tensioning mechanism; 51-Motor A; 52-Motor B; 53-Drum A; 54-Drum B; 55-Generator; 311-Flying saucer piece; 312-Encircling ring; 313-Opening and closing saucer pull rope; 314-Support rod; 315-Winder; 316-Battery; 317-Vertical axis wind turbine; 318-Side wing. The power generation system includes a helium balloon, two sets of kite-shaped flying saucer assemblies, parachute cables, and power generation facilities. The helium balloon provides the altitude for the two sets of kite-shaped flying saucer assemblies to generate wind power. The helium balloon is connected to the power generation facilities via the parachute cables. The two sets of kite-shaped flying saucer assemblies are fixedly connected to the parachute cables. The two sets of kite-shaped flying saucer assemblies are located on opposite sides of the helium balloon. Each set of kite-shaped flying saucer assemblies includes at least one power parachute. The power parachute in one set of kite-shaped flying saucer assemblies opens like louvers, while the power parachute in the other set closes like louvers, causing the parachute cables to shift and enabling continuous power generation. The power parachute also includes a winch, a battery, and a vertical axis wind turbine. The vertical axis wind turbine is fixedly connected to a limit block. The battery connects the winch and the vertical axis wind turbine. The winch is wound with a cable for opening and closing the flying saucer discs.

[0004] The aforementioned patent utilizes a vertical axis wind turbine to charge a battery, which in turn powers a winch. The winch pulls the cable connecting the opening and closing discs, thus enabling continuous power generation. However, the power generation of the vertical wind turbine is affected by various factors, such as wind speed and direction. If the vertical wind turbine malfunctions or its output is insufficient, the discs will be unable to switch states, causing the system to degrade into single-unit operation, losing its continuous power generation capability and entering an intermittent power generation mode.

[0025] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0026] like Figures 4-7 As shown, a power generation device accompanying a flying wind turbine is disclosed. The flying wind turbine includes a flying power-generating device 1400 and a tethering cable 1200. The flying power-generating device 1400 includes a flying connection assembly 1410, a flight control device 1420, and a flying component 1430. The flying power-generating device 1400 can reciprocate along the tethering cable 1200. The accompanying power generation device 4000 is disposed within the flying connection assembly 1410 and includes: The transmission mechanism includes a gear 4100, and a rack 4200 that meshes with the gear 4100 is provided on the tether cable 1200. The gear 4100 is fixedly installed on the flight connection assembly 1410. The generator 4300 is connected to the gear 4100 and is driven by the gear 4100 to rotate and generate electricity; When the flight power device 1400 reciprocates along the mooring cable 1200, the gear 4100 and rack 4200 mesh together, driving the generator 4300 to generate electricity to power the flight control device 1420.

[0027] Through the meshing motion of gears 4100 and rack 4200, the accompanying power generation device 4000 can continuously generate electricity throughout the reciprocating motion of the flight power unit 1400. This provides a stable and reliable power source for the flight control device 1420, ensuring the continuous operation and safety of the flying wind turbine. The design of the accompanying power generation device 4000 fully utilizes the mechanical energy generated during the reciprocating motion of the flight power unit 1400, efficiently converting it into electrical energy through the gear 4100 and rack 4200 mechanism. Because the accompanying power generation device 4000 can self-sufficiently power the flight control device 1420, the flying wind turbine reduces its dependence on external power sources during operation, enhancing the system's independence and reliability.

[0028] like Figures 4-6 As shown, in some embodiments, the gear 4100 and the generator 4300 are coaxially directly connected, and the generator 4300 is a multi-pole DC generator 4300.

[0029] In the aforementioned flying wind turbine accompanying power generation device 4000, the gear 4100 and the generator 4300 are designed with a coaxial direct connection, and the generator 4300 is selected as a multi-pole DC generator 4300. The specific working principle is as follows: Gear 4100 and generator 4300 are directly connected via the same shaft, ensuring synchronized rotational motion and no relative slippage between them. When gear 4100 rolls on rack 4200, its rotational motion is directly transmitted to generator 4300, driving the rotor inside generator 4300 to rotate. The multi-pole DC generator 4300 has multiple magnetic pole pairs, each generating a fixed magnetic field. When the rotor (the rotating part of generator 4300) rotates within these magnetic fields, it cuts magnetic field lines, inducing an electromotive force in the rotor coils, thus generating direct current. The multi-pole design increases the frequency of magnetic field changes inside generator 4300, enabling it to generate higher voltage and greater current at the same rotational speed, thereby improving power generation efficiency.

[0030] The coaxial direct-drive design reduces energy loss during transmission, ensuring efficient transmission of the rotational motion of gear 4100, enabling generator 4300 to fully receive and utilize mechanical energy for power generation. The multi-pole DC generator 4300 increases the energy conversion efficiency per unit time by increasing the frequency of magnetic field changes, allowing it to output more electrical energy under the same conditions. The high integration, small size, and light weight of the multi-pole DC generator 4300 help reduce the overall weight of the flying wind turbine, improving its flight performance and energy utilization efficiency. The combined design of coaxial direct drive and multi-pole DC generator 4300 offers strong adaptability, capable of meeting power generation needs under different wind speeds and flight conditions.

[0031] like Figure 7 As shown, in some embodiments, the gear 4100 is connected to the generator 4300 via a set of gears 4100. The set of gears 4100 consists of multiple gears 4100 of different sizes. Through the meshing transmission of these gears 4100, the speed and torque can be changed between the input shaft (connected to the gear 4100 in the flight connection assembly 1410) and the output shaft (connected to the generator 4300).

[0032] like Figure 4 and Figures 6-7 As shown, in some embodiments, the tethering cable 1200 includes a rack segment and a flexible cable segment, the rack segment being disposed within the reciprocating stroke range of the flight power device 1400, and the flexible cable segment being connected to the end of the rack segment.

[0033] The rack segment is positioned within the reciprocating stroke range of the flight power device 1400, and its surface is machined with a rack 4200 structure. When the flight power device 1400 reciprocates up and down along the tether cable 1200, the gear 4100 within the flight connection assembly 1410 meshes with the rack 4200 structure of the rack segment. As the flight component 1430 reciprocates, the gear 4100 rolls on the rack 4200, thereby converting the linear motion of the flight component 1430 into the rotational motion of the gear 4100.

[0034] The meshing design of the rack segment and gear 4100 provides a stable mechanical energy conversion path, ensuring that the reciprocating motion of the flight component 1430 can be efficiently converted into the rotational motion of the gear 4100, thereby driving the generator 4300 to generate electricity. Through the accompanying power generation device 4000, the flying wind turbine can continuously and stably generate electricity during flight, providing reliable power support for the flight control device 1420 and ensuring the smooth progress of the flight mission.

[0035] like Figures 6-7 As shown, in some embodiments, the rack 4200 is an embedded rack 4200, disposed within or on a surface groove of the tether 1200. The embedded rack 4200 is disposed within or on a surface groove of the tether 1200. This design, through the manufacturing process of the tether 1200, embeds the rack 4200 structure into a groove at a specific location within or on the surface of the tether 1200, making the rack 4200 and the tether 1200 a single unit. When the flight power unit 1400 reciprocates along the tether 1200, the gear 4100 within the flight connection assembly 1410 meshes with the rack 4200 embedded in the tether 1200. Since the rack 4200 is fixed (relative to the tether 1200), the rotational motion of the gear 4100 is driven by the linear motion of the rack 4200, thereby driving the generator 4300 connected to the gear 4100 to generate electricity. In some other embodiments, the tether cable 1200 is directly machined into a rack 4200 on the side near the gear 4100. In this embodiment, the tether cable 1200 is directly machined into a rack 4200 structure on the side near the gear 4100. The rack 4200 and the tether cable 1200 are integral structures made of the same material, without the need for additional embedding or assembly steps.

[0036] In some embodiments, the device further includes an energy storage device electrically connected to the generator 4300 and the flight control device 1420, for storing electrical energy and supplying power to the flight control device 1420 when power generation is insufficient.

[0037] Due to the unstable and intermittent nature of wind power, the output power of generator 4300 fluctuates with changes in wind speed. The presence of an energy storage device can effectively smooth out these power fluctuations, storing excess energy when power generation is sufficient and releasing energy when power generation is insufficient, providing a continuous and stable power supply to flight control device 1420. This prevents flight control device 1420 from malfunctioning due to insufficient power generation, thereby ensuring the stable operation of the entire wind turbine unit.

[0038] In some embodiments, the device further includes a DC-DC converter disposed between the energy storage device and the power supply port for stabilizing the output voltage.

[0039] During the operation of the wind turbine, the output voltage of the energy storage device may fluctuate due to various factors, such as the charging and discharging state of the energy storage device and changes in load. The DC-DC converter can convert these unstable DC voltages into stable DC voltages, providing high-quality power to the power supply port and ensuring that the equipment connected to the power supply port (such as the flight control device 1420) can work normally in a stable voltage environment, avoiding equipment performance degradation, damage or even failure due to voltage fluctuations.

[0040] like Figures 6-7 As shown, in some embodiments, the device further includes a limiting mechanism and a positioning pulley 4400. The limiting mechanism is used to limit the meshing position of the gear 4100 and the rack 4200 to prevent disengagement, and the positioning pulley 4400 is used to maintain the meshing pressure of the gear 4100 and the rack 4200.

[0041] The limiting mechanism typically consists of components such as a stop or a limiting rod fixed to the mooring cable 1200 or related structures. During the normal meshing motion of gear 4100 and rack 4200, gear 4100 reciprocates linearly along rack 4200. When gear 4100 reaches a preset limit position, the stop or limiting rod on the limiting mechanism will mechanically contact a specific part of gear 4100 (such as the edge or shaft of gear 4100), preventing gear 4100 from continuing to move in that direction, thus limiting the meshing position of gear 4100 and rack 4200. During the operation of the flying wind turbine, due to factors such as the instability of wind power and the motion inertia of the flying power unit 1400, gear 4100 and rack 4200 may experience excessive displacement, leading to disengagement. The limiting mechanism effectively limits the range of motion of gear 4100, ensuring that gear 4100 always maintains the correct meshing state with rack 4200, improving the stability and reliability of the entire transmission system.

[0042] The positioning pulley 4400 applies appropriate meshing pressure to the rack 4200, ensuring full contact between the tooth surfaces of the gear 4100 and the rack 4200, reducing slippage and backlash between the tooth surfaces, thereby improving transmission efficiency. By maintaining the meshing pressure between the gear 4100 and the rack 4200, the positioning pulley 4400 reduces energy loss during transmission, allowing more energy to be effectively transferred to the generator 4300, thus improving power generation efficiency.

[0043] Please see Figures 4-7 Based on the same inventive concept, this specification provides a flying wind turbine unit, comprising: The tether cable 1200 is fixed to the ground at one end and connected to the levitation device 1100 at the other end, limiting its flight range and also serving as a guide track for the reciprocating motion of the flight power device 1400. Under the action of wind, the flight power device 1400 can perform regular reciprocating motion along the tether cable 1200, ensuring the stability and controllability of the motion; The flight power device 1400 includes a flight connection assembly 1410, a flight control device 1420, and a flight component 1430. The flight control device 1420 is connected to the flight component 1430 through multiple parachute lines 1431. The flight power device 1400 can reciprocate along the mooring line 1200. The ground power generation device 3000 includes a cable-wheel generator 3100 installed on the ground, and a flight power-generating device 1400 connected to the cable-wheel generator 3100 via a transmission cable 1300, which converts the reciprocating motion of the flight power-generating device 1400 into electrical energy. And a power generation device 4000 as described above, disposed within the flight connection assembly 1410, for continuously supplying power to the flight control device 1420. The power generation device 4000, disposed within the flight connection assembly 1410, operates based on a specific energy conversion mechanism (such as the gear 4100 and rack 4200 transmission, energy storage device, etc. mentioned above). During the movement of the flight power device 1400, the power generation device 4000 utilizes its internal mechanical structure and energy conversion elements to convert part of the mechanical energy of the flight power device 1400 into electrical energy, which, after voltage stabilization and regulation, continuously supplies power to the flight control device 1420, ensuring that the flight control device 1420 can operate normally at all times.

[0044] In practice, the flight component 1430 is an openable power parachute. The flight control device 1420 adjusts the attitude of the power parachute through multiple parachute lines 1431 to change the flight state. Through the precise adjustment of the power parachute's attitude by the flight control device 1420, stable flight of the flight power device 1400 can be achieved. The flight control device 1420 can optimize the trajectory of the power parachute based on wind speed, wind direction, and the motion state of the flight power device 1400.
