Description

Technical Field

[0001] This invention relates to the field of aerial equipment power replenishment technology, and more specifically, to an aerial equipment power replenishment system. Background Technology

[0002] High-altitude wind energy is a clean and renewable energy source with great development potential. Compared with near-surface wind energy, high-altitude wind energy has the advantages of higher energy density and stronger wind speed stability, making it an important research direction in the field of new energy technology. In high-altitude wind power generation systems, supplementary power equipment is the core guarantee for providing stable power supply to various electrical devices in the air. The quality of the supplementary power solution directly affects the operational reliability and economy of the entire power generation system.

[0003] Existing high-altitude wind energy systems mostly employ in-flight self-generation supplementation schemes, powering equipment by mounting photovoltaic or small wind turbine devices in the air. However, this approach suffers from low power generation efficiency, heavy aerial loads, and poor environmental adaptability. Because airborne power generation devices cannot actively adjust their attitude according to sunlight angle and wind direction, the conversion efficiency between photovoltaic and wind energy is low, and it is also constrained by day / night cycles and weather conditions, making it impossible to achieve stable all-weather power supply. Secondly, a complete airborne power generation system includes multiple components such as power generation modules, mounting brackets, and control circuits, increasing the aerial load and requiring an upgrade in the lift specifications of the floating support structure, thus raising the system's construction and maintenance costs. Furthermore, suspending numerous supplementation devices on cables increases cable load, affecting the parachute's working efficiency and resulting in low cable power generation efficiency.

[0004] In summary, existing aerial self-generated power replenishment schemes suffer from low replenishment efficiency, large aerial equipment weight, and poor environmental adaptability, resulting in high weight, high cost, and insufficient operational stability of high-altitude wind power generation systems. There is an urgent need for an aerial equipment replenishment system with centralized ground power supply to solve the above-mentioned technical defects. Summary of the Invention

[0005] The present invention aims to overcome at least one of the defects of the prior art and provide an aerial equipment power replenishment system to solve the problems of low power replenishment efficiency, large weight of aerial equipment and poor environmental adaptability of existing aerial self-generated power replenishment schemes.

[0006] The technical solution adopted by this invention is an aerial equipment recharging system, comprising a ground recharging device and an aerial power generation device; the ground recharging device includes a power supply device and a conductive transfer device; the aerial power generation device includes a power supply cable structure, a power umbrella, and a power umbrella recharging device, the power umbrella recharging device being disposed on the power supply cable structure, and the power umbrella being connected to the power umbrella recharging device; the power supply cable structure is electrically connected to the conductive transfer device, and the conductive transfer device transmits the electrical energy provided by the power supply device to the power umbrella recharging device through the power supply cable structure.

[0007] The ground-based power replenishment device includes power supply equipment and conductive transfer equipment. The power supply equipment comprises a power source, an energy storage module, and a voltage booster module. The power source transmits electrical energy to the energy storage module, and then the voltage booster module performs high-voltage transmission. High-voltage transmission effectively reduces the diameter and weight of the power cable structure while minimizing energy loss. The power source can be selectively connected to various power sources such as wind power, photovoltaic power, or plant power, and is unaffected by environmental factors such as high-altitude sunlight angle, day-night cycle, and wind direction changes, enabling a stable all-weather power supply. The energy storage module has a capacity of at least three times the total energy required by the aerial power generation device. The voltage booster module increases the voltage, allowing for efficient transmission of electrical energy to the aerial power generation device. The conductive transfer equipment, through its automatic telescopic and rotatable design, flexibly connects to the power cable structure, achieving stable high-voltage power transmission. By relocating the power generation, energy storage, and voltage boosting processes to the ground, the ground-based power replenishment device reduces the overall weight of the aerial power generation components, mounting brackets, and control circuits.

[0008] The aerial power generation unit includes a power cable structure, a power parachute, and a power parachute recharging device. Electrical energy is directly transmitted to the power parachute recharging device via the power cable structure. The power parachute recharging device not only moves in tandem with the power parachute but also charges the connection between the recharging device and the power parachute. Recharging efficiency is unaffected by high-altitude environmental fluctuations, reducing the need for additional aerial power generation equipment and improving the operational stability and overall economy of the aerial power generation unit. The reduced aerial load also decreases the size requirements of the aerostat, lowering the demands on aerostat materials and manufacturing processes, further reducing costs. Simultaneously, fewer devices are suspended on the power cable structure, and the curvature of the cable is reduced, which is beneficial for improving power generation efficiency and wind energy conversion rate. When the aerial power generation unit needs recharging, it is lowered to a reasonable operational height. A conductive transfer device transmits the electrical energy provided by the power supply equipment to the power parachute recharging device via the power cable structure. Once recharging is complete, the conductive transfer device disconnects from the power cable structure.

[0009] Furthermore, the conductive adapter includes a conductive cable, a base, and a universal joint. The base supports the universal joint, and the universal joint enables the cable rope structure to rotate in the horizontal and vertical planes. The conductive cable starts from the power supply equipment, passes through the base and the universal joint, and then connects to the cable rope structure.

[0010] During the power replenishment process, the conductive transfer device transmits the electrical energy provided by the power supply equipment to the power supply umbrella power replenishment device through the power cable rope structure. At this time, the conductive cable is electrically connected to the power supply cable rope. The electrical energy output by the power supply equipment is transmitted to the power supply cable rope structure through the conductive cable. The power supply cable rope structure will deflect horizontally with changes in wind direction and adjust its vertical tilt angle with changes in wind speed. The posture of the power supply cable rope structure is always in a dynamic state of change. The base provides a stable ground support foundation for the entire conductive transfer device, and the universal joint adapts to the two-dimensional angle changes of the power supply cable rope structure, allowing the internal conductive cable to rotate synchronously with the power supply cable rope structure, avoiding the conductive cable from twisting, pulling, or even breaking due to the deflection of the power supply cable rope structure. The conductive transfer design, which can adaptively rotate at multiple angles, not only ensures the continuity of the power transmission path from the ground to the air, but also reduces the damage to the conductive cable caused by the turning of the power supply cable rope structure, improving the operational reliability and service life of the power supply link.

[0011] Furthermore, the universal joint includes a first conductive ring, a base, and a rotating seat. The first conductive ring connects the base and the base, and the rotating seat is connected to the base via a transverse rotating shaft. The first conductive ring enables the base to rotate on the base, and the conductive cable passes from the base through the first conductive ring and the base. The transverse rotating shaft enables the rotating seat to rotate on the base, and the conductive cable passes from the base through the rotating seat.

[0012] The first conductive ring provides an uninterrupted rotating conductive path for the horizontal rotation of the base, allowing the base to freely rotate 360° in the horizontal direction of the cable, maintaining continuous circuit conduction throughout the process. The lateral pivot supports the rotating seat to complete the vertical pitch swing, adapting to the tilt angle adjustment of the power supply cable structure due to wind speed changes. Through the two-dimensional degree of freedom design of horizontal and pitch rotation, the universal joint can change with the real-time posture of the power supply cable structure, ensuring that the conductive cable maintains a stable connection with the power supply cable structure under any wind direction and tilt angle. This avoids the problems of cable twisting, knotting, and bending fatigue, as well as the risk of power outage during rotation, ensuring the continuity and stability of high-altitude power replenishment operations.

[0013] Furthermore, the universal joint also includes an automatic telescopic cable reel assembly, which is disposed on the rotating base. The automatic telescopic cable reel assembly includes at least a second conductive ring and a winding roller. The conductive cable passes from the rotating base through the second conductive ring and the winding roller and is then connected to the cable supply rope structure.

[0014] Dynamic changes in wind speed cause tension fluctuations and elastic deformation in the power supply cable structure. If the length of the conductive cable is fixed, the cable is easily damaged or broken during the power replenishment process due to the stretching of the electrical connection between the cable and the power supply cable structure. Conversely, the cable is prone to loosening and tangling with the equipment during the contraction of the power supply cable structure, leading to frictional damage. The second conductive ring ensures continuous circuitry during the cable winding and unwinding process. Optionally, the winding roller, in conjunction with a built-in tensioning device, can automatically wind and unwind the cable, matching the real-time expansion and contraction of the power supply cable structure to maintain appropriate tension in the conductive cable. The automatic telescopic reel assembly counteracts the dynamic expansion and contraction of the power supply cable structure, preventing damage to the conductive cable due to sudden tension changes. It also ensures that the conductive cable never comes into contact with non-rotating equipment, reducing frictional losses and safety hazards. This further enhances the conductive cable's adaptability to complex wind conditions, extends its service life, and ensures a stable and continuous electrical connection between the conductive cable and the power supply cable structure during power replenishment.

[0015] Furthermore, the power umbrella charging device includes an upper drive charging system, an upper driver, a lower driver, and a lower drive charging system arranged sequentially along the power cable structure; the upper drive charging system and the lower drive charging system are spaced apart and fixed to the power cable structure, and the upper drive charging system and the lower drive charging system are charged by transmitting electrical energy through the power cable structure; the upper driver and the lower driver are connected to the power umbrella, and the upper driver and the lower driver move in coordination with the power umbrella; the upper driver is charged when connected to the upper drive charging system, and the lower driver is charged when connected to the lower drive charging system.

[0016] Both the upper and lower drive power supply systems integrate a step-down module, a charging module, and an energy storage battery. A photovoltaic power supply system can be added to the casing for auxiliary power supply. The step-down module converts the high-voltage power transmitted via the conductive cable into a working voltage matching the energy storage battery. The energy storage battery stores energy for at least one operating cycle; its capacity can be calculated based on the local wind speed intervals. The charging module connects to the upper and lower drive systems to control charging and transmit power. The upper and lower drive systems, as the motion actuators for the power umbrella, are equipped with small-capacity batteries. These batteries have a capacity no less than twice the energy consumption of a single umbrella opening / closing cycle. Under extreme conditions, only a single umbrella opening / closing action is required, eliminating the need for a large-capacity energy storage battery to cover the entire operating cycle. During operation, the lower drive system automatically connects to the charging circuit when it reaches the lower drive power supply system position. Except during umbrella closing, it remains connected to the lower drive power supply system. The upper drive system maintains a continuous connection with the upper drive power supply system during power generation, fully charging its battery after each power umbrella cycle. The fixed upper and lower drive power supply system, along with the coordinated movement of the upper and lower actuators, achieves functional and physical separation between the energy storage battery and the device battery. This reduces the weight of the upper and lower actuators, lowers motion energy consumption, and consequently reduces the capacity requirements of the device battery, further reducing the weight of the aerial power generation device. The separate power supply design ensures stable power supply throughout the entire operation cycle of the power parachute, while also reducing system operating energy consumption through lightweight moving parts. Furthermore, the photovoltaic power supply design on the system's casing allows for on-site utilization of solar energy to supplement power, further enhancing the system's power supply efficiency and environmental adaptability.

[0017] Further, the cable supply rope structure includes a multi-strand cable, a composite cable, and a connector; the multi-strand cable includes a parallel transmission trunk and a multi-strand load-bearing bundle, the transmission trunk being fixedly disposed around the multi-strand load-bearing bundle; the composite cable has a coaxial layered structure with a hollow conductive cavity inside, the transmission trunk passing through the hollow conductive cavity; the connector includes a housing and a hollow fixing member, the hollow fixing member being disposed within the housing; the transmission trunk branches off at least one transmission branch at the location of at least one connector, the transmission branch extending forward along the connector... Extending backward or simultaneously forward and backward, and fixed side-by-side to the periphery of the multi-strand cable or composite cable; the multi-strand cable is divided into two groups: a first multi-strand cable and a second multi-strand cable. The first multi-strand cable and the second multi-strand cable are connected in series with multiple groups of composite cables via the connector. The number of groups of the power umbrella energy replenishment device is the same as the number of groups of the composite cable. The power umbrella energy replenishment device is mounted on the composite cable. The transmission trunk of the composite cable is electrically connected to the power umbrella energy replenishment device via the transmission branch. The transmission trunk of the first multi-strand cable is electrically connected to the conductive adapter.

[0018] Multi-strand cables are laid out in parallel with the load-bearing bundle, while composite cables embed the transmission trunk within a hollow conductive cavity. Compared to the traditional method of independently binding the power transmission cable to the outside of the load-bearing cable, this reduces the overall outer diameter and weight of the cables, lowers wind resistance during high-altitude operation, and avoids aging caused by wind and friction after the cable is exposed, thus improving the service life and operational reliability of the cables in harsh high-altitude environments. The connectors adopt a hollow structural design, balancing the dual requirements of load-bearing connection and power transmission continuity. On the one hand, the hollow fasteners can achieve a stable mechanical connection between multi-strand cables and composite cables, as well as between adjacent composite cables, ensuring the axial load-bearing strength of the cables and meeting the high-load suspension requirements of high-altitude parachute ladder systems. On the other hand, the hollow fasteners provide a continuous passage for the transmission trunk, supporting long-distance power transmission from the ground end to the high-altitude end, adapting to efficient power replenishment systems for ground-based voltage boosting and high-voltage transmission, and reducing the diameter and weight of the cables. The transmission trunk line can flexibly branch off into transmission branches at the connector location and extend forward, backward, or bidirectionally along the perimeter of the cable. This allows for precise matching of aerial electrical equipment at different heights, enabling distributed power supply distribution. It solves the shortcomings of existing high-altitude cables that cannot flexibly deploy power supply branches and are difficult to adapt to multiple equipment power replenishment. It provides structural support for ground-based centralized power replenishment solutions, eliminating the need to carry additional self-generating devices in the air and fundamentally reducing the overall load on the aerial system.

[0019] The system employs a modular, series-connected architecture with multi-strand cables at both ends and multiple sets of composite cables in the middle. The multi-strand cables at both ends can be adapted to connect to the ground-based and high-altitude top ends respectively, directly interfacing with ground-based power replenishment devices and aerobatic equipment. This solves the weight problem associated with adding small power generation devices for power supply in traditional cables. The multiple sets of composite cables in the middle correspond to the deployment sections of each aerial equipment segment, with each composite cable segment corresponding to a set of power parachutes and their power replenishment equipment. This modular structure allows for flexible adjustment of the number of composite cable sets in series based on the total length of the ladder and the number of power parachutes, adapting to power generation systems of different installed capacities. It possesses strong versatility and scalability, facilitating standardized production and on-site assembly and commissioning.

[0020] The transmission trunk of the composite cable is electrically connected to the power umbrella power supply device through the transmission branch. The transmission branch can be flexibly divided according to the deployment position of the power umbrella, so as to provide power to the power umbrella power supply device at the corresponding position. This solves the problem of the difficulty of single-path connection and branch deployment of traditional cables and is suitable for high-altitude parachute power generation layout with multiple umbrellas connected in series. The transmission trunk of the first multi-strand cable is electrically connected to the conductive adapter. During power supply, the electrical energy of the conductive cable is transmitted to the power supply cable structure through the electrical connection with the transmission trunk. The conductive cable and the transmission trunk of the first multi-strand cable are connected by an aviation plug. After power supply is completed, the plug can be unplugged. The power supply operation is simple and convenient, improving the efficiency of power supply work.

[0021] Furthermore, the transmission trunk line passes through the hollow fixing member of the connector from the periphery of the first multi-strand cable and enters the hollow conductive cavity of the composite cable, then passes through the hollow conductive cavity of the previous composite cable, through the hollow fixing member of the next connector, and enters the hollow conductive cavity of the next composite cable. After passing through multiple sets of composite cables, the transmission trunk line passes through the hollow conductive cavity of the last set of composite cables, through the hollow fixing member of the connector, and then passes through the periphery of the second multi-strand cable.

[0022] The transmission trunk line runs sequentially along the cable axis, connecting all the connected cable segments to form a continuous and complete high-voltage transmission trunk line. This continuous layout ensures stable long-distance power transmission from the ground to the highest point in the sky, reduces power loss, and is well-suited for power replenishment schemes after ground-based voltage boosting. This effectively reduces line losses in long-distance power transmission, thereby allowing for a reduction in cable diameter and overall weight. Furthermore, the transmission trunk line is embedded within or integrated with load-bearing structures throughout, preventing cable fatigue damage caused by high-altitude wind vibration and improving the stability and reliability of long-distance power transmission.

[0023] Furthermore, the composite cable is configured in two parts, namely a first composite cable and a second composite cable. The first multi-strand cable, the first composite cable, the second composite cable and the second multi-strand cable are connected in series via connectors. The transmission trunk line extends from the position of the connector between the first multi-strand cable and the first composite cable, the second composite cable and the second multi-strand cable to form one branch respectively. The transmission trunk line extends from the position of the connector between the first composite cable and the second composite cable to form two branches.

[0024] Two sets of composite cables are installed with power supply branches at three connector locations to accommodate two sets of aerial parachute devices. Each connector at both ends branches out a branch, which can respectively meet the power supply needs of the ground-based energy replenishment system and the lift guide body. The middle connector branches out two bidirectional branches, which can simultaneously supply power to the energy replenishment equipment on both the upper and lower sides. This precisely matches the distributed power supply layout, optimizes the integration of the cables, and enables a single main line to supply power to multiple sets of aerial equipment at the same time. This supports the implementation of ground-based energy replenishment solutions, replaces the traditional aerial self-generated energy replenishment mode, and effectively reduces the overall weight of the aerial system.

[0025] Furthermore, an aviation plug is provided inside the hollow fixing component, and the transmission trunk line forms a transmission branch line through the aviation plug; multiple protrusions are provided on the two ends of the outer wall of the hollow fixing component, and a fixing groove is formed between adjacent protrusions.

[0026] An aviation plug is integrated inside the hollow fixing component as a power transmission branch node. The aviation plug enables a fast and reliable electrical connection between the main transmission line and its branches, ensuring the contact stability and insulation protection performance of high-voltage power transmission. It also facilitates the segmented modular assembly of the cable and subsequent maintenance. The aviation plug and branches of the main transmission line are housed within the hollow cavity of the connector, preventing exposure to the high-altitude environment and effectively resisting external environmental factors. This also prevents the branch structure of the main transmission line from protruding from the cable surface, increasing wind resistance, or becoming entangled with foreign objects, thus protecting the power transmission node and extending the cable's service life. A protrusion forming a fixing groove is provided on the outer wall of the hollow fixing component for the attachment and fixing of multi-strand cables and / or composite cables. The multi-strand load-bearing bundles can be embedded in the fixing groove for limiting their position, and the protrusion provides lateral obstruction to the multi-strand load-bearing bundles, preventing them from slipping off the sides under stress. This structure evenly transfers the axial tension of the cable to the hollow fixing component body through the fixing groove. The mechanical transmission path is clear and reliable. The multiple load-bearing bundles form a continuous contact surface with the fixing groove, increasing the stress-bearing area. Compared with the traditional single cable load-bearing method, the hollow fixing component improves the load-bearing capacity and structural stability. The protrusions are arranged on the outer wall of the hollow fixing component, without occupying internal power transmission installation space. This achieves spatial isolation between the mechanical load-bearing function and the power transmission branch function, avoiding mutual interference and ensuring the independent and stable operation of both functions.

[0027] Furthermore, the composite cable also includes an isolation layer and a protective layer. The isolation layer wraps around the transmission trunk line, and multiple load-bearing bundles are coaxially arranged outside the isolation layer. The protective layer wraps around the multiple load-bearing bundles. The multiple load-bearing bundles of the multi-strand cable and / or composite cable are equally divided and woven into a pipa-shaped hanging ring. The shape of the fixing groove matches the hanging ring, and the hanging ring is fixedly embedded in the fixing groove.

[0028] The composite cable adopts a coaxial, layered structure, consisting of, from the inside out, the transmission trunk, an isolation layer, multiple load-bearing bundles, and a protective layer. The isolation layer encases the transmission trunk, ensuring reliable electrical insulation between it and the outer multiple load-bearing bundles, preventing leakage or breakdown risks in high-voltage transmission, and buffering the compression damage to the transmission trunk caused by the deformation of the multiple load-bearing bundles. The multiple load-bearing bundles are evenly distributed coaxially along the circumference, evenly bearing the axial tensile force of the cable and ensuring its overall load-bearing strength. The outermost protective layer isolates the cable from external environmental influences and reduces frictional losses during operation, providing comprehensive protection for the internal load-bearing structure and transmission lines, thus improving the service life and operational safety of the composite cable in harsh high-altitude environments.

[0029] Multiple load-bearing bundles are equally divided and braided into pipa-shaped hooks, which are then embedded into matching fixing grooves to complete the connection. The pipa-shaped braided hook structure can evenly distribute the axial tension of the cable, avoiding stress concentration and breakage in a single strand, and improving the mechanical connection strength and fatigue resistance of the connector. This makes it suitable for high-load and long-term reciprocating stress applications in high-altitude wind energy systems. The embedded fit between the hooks and the fixing grooves allows for precise positioning of the multiple load-bearing bundles and the hollow fixing components. No additional complex fasteners are required during assembly, making installation convenient and the connection stable. At the same time, the multiple load-bearing bundles are evenly distributed along the circumference of the fixing groove, forming a continuous contact surface, increasing the stress area, and improving the cable's load-bearing capacity and structural stability. Furthermore, it does not occupy internal power transmission channel space, achieving non-interference and coordinated operation between the load-bearing structure and the power transmission structure.

[0030] Compared with existing technologies, the advantages of this invention are as follows: Ground-based centralized power supply is achieved through a ground-based energy replenishment device, replacing the traditional aerial self-generation scheme. This fundamentally reduces the weight of the aerial power generation device. The energy replenishment process is not constrained by environmental factors, enabling stable power supply around the clock. Simultaneously, it reduces the size and manufacturing requirements of the aerostat, lowering construction and maintenance costs. Furthermore, the use of a conductive transfer device with two-dimensional rotation and automatic extension / retraction functions allows the conductive cable to adaptively adjust to the wind direction and deformation of the power cable, preventing twisting, pulling, and slack damage, thus ensuring the continuous conduction and operation of long-distance high-voltage transmission paths. It boasts high reliability and adapts to the energy replenishment needs under complex wind conditions at high altitudes. The separate energy replenishment design fixes the energy storage battery to the power supply cable structure, with only small-capacity batteries configured for the upper and lower drives, reducing the weight of moving parts and lowering operating energy consumption, thus ensuring the stability of power supply throughout the entire operation cycle of the power umbrella. The integrated load-bearing and power transmission power supply cable structure effectively reduces the diameter and weight of the power supply cable structure. The connectors combine load-bearing connection and power supply branching functions, allowing for flexible branching to adapt to multiple equipment energy replenishment. The modular series architecture can adapt to power generation systems of different installed capacities, offering strong versatility and scalability. Attached Figure Description

Detailed Implementation

[0043] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

These terms are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Example 1 like Figure 1 As shown, this embodiment is an aerial equipment power supply system, including a ground power supply device and an aerial power generation device. The ground power supply device undertakes the functions of power supply, energy storage and voltage regulation and power transmission and transfer. The aerial power generation device realizes power generation through high-altitude wind energy and receives the power transmitted from the ground through the power cable structure 3 to complete the power supply of its own equipment.

[0046] The ground-based power replenishment device includes power supply equipment 1 and conductive transfer equipment 2.

[0047] The power supply equipment 1 includes a power source 11, an energy storage module 12, and a boost module 13. The power source 11 transmits electrical energy to the energy storage module 12, and then the boost module 13 transmits it at high voltage. High-voltage transmission can effectively reduce the diameter and weight of the power cable structure 3, while reducing energy loss. The power source 11 can be selectively connected to various power sources such as wind power, photovoltaic power, or plant power, and is not restricted by environmental factors such as the angle of high-altitude illumination, day and night alternation, and wind direction changes, enabling a stable all-weather power supply. The capacity of the energy storage module 12 is not less than three times the total energy required by the aerial power generation device, and can be calculated based on the interval between the cut-in wind speed and the cut-out wind speed of local wind resources. The boost module 13 can increase the voltage, so that electrical energy can be efficiently transmitted to the aerial power generation device. Under the same transmission power, the higher the voltage, the smaller the line current, which can effectively reduce the conductor cross-sectional area of ​​the transmission cable, thereby reducing the weight of the cable itself and adapting to the design requirements of lightweight high-altitude applications.

[0048] like Figure 2 As shown, the conductive adapter 2 includes a conductive cable 21, a base 22, a universal joint 23, and an automatic telescopic cable reel assembly 234, which performs the functions of fixed support, two-dimensional steering conductivity, and telescopic tensioning. The base 22 is made of heavy-duty cast steel and is fixed to the ground with anchor bolts, providing a stable support foundation for the universal joint 23 and preventing the equipment from shifting or tipping over due to changes in tension.

[0049] The universal joint 23 is mounted above the base 22 and includes a first conductive ring 231, a base 232, a rotating seat 233, and an automatic telescopic cable reel assembly 234. The universal joint 23 can achieve 360° rotation in the horizontal plane and two-dimensional freedom of pitch and oscillation in the vertical plane, adapting to the attitude changes of the cable rope structure 3 caused by wind direction and wind speed. The first conductive ring 231 is an electric slip ring structure that connects the base 22 and the base 232. It consists of a stationary stator and a rotating rotor, ensuring that the circuit remains continuously conductive during the horizontal rotation of the base 232, preventing the conductive cable 21 from twisting, knotting, or being damaged. Two transverse pivot supports are symmetrically arranged on the upper part of the base 232. The rotating seat 233 is hinged between the two supports through the transverse pivot and can swing in the vertical plane from 45° to 90° around the transverse pivot to adapt to different inclination angles of the cable. Optionally, an arc-shaped limiting groove is opened on the rotating seat 233 and a limiting rod matching the width of the limiting groove is provided on the base 232. When the rotating seat 233 swings relative to the base 232 in the pitch angle, the limiting groove moves relative to the limiting rod.

[0050] The automatic telescopic cable reel assembly 234 is fixedly installed on the upper part of the rotating base 233, and rotates horizontally and tilts synchronously with the rotating base 233. It includes a second conductive ring, a winding roller, and a tensioning device. The winding roller has an I-beam structure, and the conductive cable 21 is wound orderly within the groove of the winding roller. The second conductive ring maintains continuous circuit continuity during the winding of the conductive cable 21, preventing the conductive cable 21 from twisting as the winding roller rotates. The tensioning device can adopt a constant torque spring structure, connected to the shaft of the winding roller, ensuring that the output conductive cable 21 always maintains a stable tension. When the cable supply rope structure 3 is stretched due to increased wind speed, the tensioning device drives the winding roller to release the cable, automatically releasing the length of the conductive cable 21. When the wind speed decreases and the cable supply rope structure 3 contracts, the tensioning device drives the winding roller to automatically retract the cable, recovering the excess length of the conductive cable 21, always maintaining a reasonable tension on the conductive cable 21, and preventing the conductive cable 21 from breaking due to overstretching or becoming loose and rubbing against or entangled with other equipment. The retraction and extension stroke of the automatic telescopic cable reel assembly 234 is designed according to the maximum extension and retraction of the cable, which can cover the elastic deformation range of the cable under normal wind conditions.

[0051] The conductive cable 21 starts from the power supply equipment 1, passes through the base 22, the first conductive ring 231, the base 232, the rotating seat 233, the second conductive ring, and the winding roller, and then connects to the power supply cable rope structure 3. The conductive cable 21 and the power supply cable rope structure 3 can be electrically connected via an aviation plug 7. The aviation plug 7 includes a male and a female connector, which can withstand a certain axial tensile force to prevent the aviation plug 7 from loosening during the power replenishment process. When the air-based power generation device is replenishing power, the male and female connectors are connected, and the conductive cable 21 transmits the electrical energy provided by the power supply equipment 1 to the power supply umbrella replenishment device 5 on the power supply cable rope structure 3 through the conductive transfer device 2. After charging is completed, the male and female connectors are disconnected, making the power replenishment operation convenient and quick.

[0052] The aerial power generation device includes a power cable structure 3, a power parachute 4, a power parachute refueling device 5, and a buoyancy device 6. The power parachute refueling device 5 is mounted on the power cable structure 3, and the power parachute 4 is connected to the power parachute refueling device 5. The power parachute 4 can be replaced by a balancing parachute, a balloon, or other wind energy conversion equipment. The power cable structure 3 is both the load-bearing structure that supports the weight of the entire aerial power generation device and the transmission carrier for transmitting electrical energy. The power parachute 4 is the core component for wind energy capture and conversion into power generation. The power parachute refueling device 5 is responsible for receiving the electrical energy transmitted by the power cable structure 3 and powering the drive equipment of the power parachute 4.

[0053] like Figure 3 As shown, the cable rope structure 3 includes multi-strand cables 31, composite cables 32, and connectors 35. The multi-strand cables 31 are configured in two groups, with multiple groups of composite cables 32 connected in series between the two groups of multi-strand cables 31. The multi-strand cables 31 and composite cables 32, and the composite cables 32 themselves, are connected via connectors 35. In practical engineering applications, the number of series-connected groups of composite cables 32 can be flexibly adjusted according to the installed capacity of the aerial power generation device, the number of power umbrellas 4, and the total deployment height. Each group of composite cables 32 corresponds to one set of power umbrella 4 equipment. When the system is expanded and the number of power umbrella 4 equipment groups is increased, the number of composite cables 32 and connectors 35 can be increased accordingly. This embodiment takes the most commonly used dual-set power umbrella 4 layout in high-altitude wind energy systems as an example. Two sets of composite cables 32 are set up, namely the first composite cable 323 and the second composite cable 324. These are connected in series with the multi-strand cables 31 at both ends via three connectors 35, which can meet the power supply requirements of the two sets of power umbrellas 4. The power cable structure 3 has an overall long cable-like structure, and from top to bottom includes the second multi-strand cable 312, the third connector 355, the second composite cable 324, the second connector 354, the first composite cable 323, the first connector 353, and the first multi-strand cable 311.

[0054] like Figure 4As shown, the transmission trunk line 33 is continuously arranged along the entire power cable structure 3, serving as the main channel for high-voltage power transmission. For multi-strand cables 31, the transmission trunk line 33 is located on the periphery of the multi-strand cables 31 and is arranged parallel to the multi-strand load-bearing bundles 34. For composite cables 32, the transmission trunk line 33 is arranged through the axial center of the composite cables 32. The transmission trunk line 33 starts from the periphery of the first multi-strand cable 311, passes sequentially from the center through the first connector 353, the first composite cable 323, the second connector 354, the second composite cable 324, and the third connector 355, and finally extends to the periphery of the second multi-strand cable 312. The transmission trunk line 33 of the first multi-strand cable 311 is electrically connected to the conductive cable 21 via an aviation plug 7, and the transmission trunk line 33 of the second multi-strand cable 312 is also electrically connected to the aerostat 6 via an aviation plug 7. The aerostat 6 can be a balloon or an airship. Transmission trunk line 33 adopts a high-voltage direct current transmission design, which can be used in conjunction with a ground-based power supply system to transmit power over long distances to high altitudes, effectively reducing line losses and allowing for a reduction in wire diameter to control the overall weight of the cable.

[0055] At the three connectors 35, the transmission trunk line 33 branches off into transmission branches 331 to supply power to the power umbrella charging device 5. The transmission branches 331 extend parallel to each other along the outer wall of the composite cable 32, and extend forward, backward, or both forward and backward along the connectors 35. Specifically, at the first connector 353, the transmission trunk line 33 branches off into an upward-extending transmission branch 331 to charge the adjacent lower drive charging system 54; at the second connector 354, the transmission trunk line 33 branches off into two transmission branches 331, one extending upward and the other downward, connecting the adjacent upper drive charging system 51 and lower drive charging system 54 respectively; at the third connector 355, the transmission trunk line 33 branches off into a downward-extending transmission branch 331 to charge the adjacent upper drive charging system 51. By using a main line with multiple branches, the upper drive power supply system 51 and the lower drive power supply system 54 of each set of power umbrella power supply equipment 5 can be accurately matched without the need to install additional independent power supply cables, which is suitable for the needs of high-altitude lightweighting.

[0056] The power supply cable structure 3 and the power umbrella power supply device 5 of the present invention can also charge other electrical equipment installed on the power supply cable structure 3, simply by adding a transmission branch 331 and connecting it to the electrical equipment.

[0057] The multi-strand cable 31 includes a transmission trunk line 33 and a multi-strand load-bearing bundle 34 arranged in parallel, with the transmission trunk line 33 fixedly arranged around the multi-strand load-bearing bundle 34. For example... Figure 5As shown, the composite cable 32 has a coaxial layered structure, which includes a transmission trunk 33, an isolation layer 321, a multi-strand load-bearing bundle 34, and a protective layer 322 from the inside out. Each layer is coaxially and tightly fitted, and the whole has a circular cross-section. The size ratio of each layer can be adjusted according to the tensile force and power transmission. The cross-sectional area of ​​the multi-strand load-bearing bundle 34 accounts for no less than 60% to ensure sufficient load-bearing capacity.

[0058] The transmission trunk 33 is located at the center of the composite cable 32, forming the core of the hollow conductive cavity. The transmission trunk 33 can use multi-stranded alloy wires to stably transmit DC high voltage, meeting the power transmission needs from the ground to altitudes of several thousand meters. The insulating layer 321 tightly wraps around the outside of the transmission trunk 33, forming a hollow conductive cavity. Using insulating material, it ensures reliable electrical isolation between the transmission trunk 33 and the multi-strand load-bearing bundle 34, preventing leakage or breakdown faults in high-voltage transmission, while also buffering the deformation of the multi-strand load-bearing bundle 34 from compressing the transmission trunk 33. The multi-strand load-bearing bundle 34 is coaxially arranged on the outside of the insulating layer 321 and is the main load-bearing structure of the composite cable 32. It is composed of 12 to 24 high-strength load-bearing bundles evenly woven circumferentially, made of lightweight, high-strength materials. The evenly distributed structure of the multi-strand load-bearing bundle 34 ensures uniform distribution of tensile force circumferentially, improving overall load-bearing capacity and fatigue life. The protective layer 322, woven from high-strength polyester fibers, wraps around the outermost part of the multi-strand load-bearing bundle 34. On one hand, the protective layer 322 provides physical protection to the interior, blocking erosion from high-altitude sandstorms or rain and snow, and reducing wear caused by friction between the composite cable 32 and the connector 35. On the other hand, it constrains the position of the multi-strand load-bearing bundle 34, maintaining the stability of the cross-sectional shape of the composite cable 32, while also reducing the surface drag coefficient.

[0059] like Figure 6 and 7 As shown, the connector 35 comprises two parts: a hollow fixing component 352 and a housing 351, with an internal aviation plug 7. The hollow fixing component 352 is an integrated metal structure made of high-strength aviation aluminum alloy or stainless steel. It has a rotating structure that is narrow at both ends and wide in the middle. The middle part is a cylindrical hollow cylinder 3523, with symmetrical hollow frustum sections 3524 at both ends, forming an internal installation space to accommodate the aviation plug 7 and the wiring taper. The taper of the hollow frustum section 3524 is 1:3 to 1:5 to prevent right-angle bending of the multiple load-bearing bundles 34 at the connection end. The housing 351 comprises two symmetrically arranged hollow frustum-shaped shells. The large-diameter end faces of the two shells fit together and are locked in place by circumferentially arranged fastening screws. The inner wall curved surface of the housing fits into the outer contour of the protrusion 3522 of the hollow fastener 352. After assembly, it can press the multi-strand load-bearing bundle 34 in the fixing groove from the outside to further prevent the hook ring 341 from falling out. At the same time, it forms a fully enclosed protective cavity to protect the internal power transmission components.

[0060] Multiple protrusions 3522 are circumferentially spaced at equal intervals along the outer edge of the hollow frustum sections 3524 at both ends, forming a fixing groove between adjacent protrusions 3522. In this embodiment, eight fixing grooves are provided at each end, corresponding one-to-one with the eight sets of load-bearing bundles of the composite cable 32. The width of the fixing groove matches the diameter of the multi-strand load-bearing bundles 34, and the groove depth is not less than 1.5 times the diameter of the load-bearing bundle. The pipa-shaped hook 341 woven from the multi-strand load-bearing bundles 34 can be embedded in the fixing groove. The protrusions 3522 on both sides form lateral restraints to prevent the multi-strand load-bearing bundles 34 from slipping off under force, ensuring reliable transmission of tension.

[0061] The aviation plug 7 is fixedly installed in the central cylindrical body of the hollow fixing part 352. It includes a male and a female connector that are connected to each other. The male and female connectors are respectively connected to the transmission trunk 33 of the two cable sections to realize the continuous connection of the trunk. The aviation plug 7 is provided with a branch terminal, which can lead out one or more transmission branches 331 to realize the one-in-multiple-out branching function.

[0062] The connection between the multi-strand cable 31 and the composite cable 32 is mainly used at the lower and upper ends of the parachute ladder. The multi-strand load-bearing bundle 34 of the multi-strand cable 31 has the same material and number of strands as the multi-strand load-bearing bundle 34 of the composite cable 32. The multi-strand cable 31 is mainly used to connect with the ground-based energy replenishment device and the aerostat 6, and connects to the generator set for wind power generation during power generation. The external transmission trunk line 33 facilitates connection operations with the conductive cable 21 and the aerostat 6 lines, adapting to the installation and maintenance scenarios at the ends.

[0063] like Figure 8 As shown, when connecting the multi-strand cable 31 and the composite cable 32, the ends of the two cables are first processed separately. The multi-strand load-bearing bundle 34 at the end of the multi-strand cable 31 is divided into 8 equal groups and woven into a pipa-shaped hanging ring 341. Similarly, the multi-strand load-bearing bundle 34 at the end of the composite cable 32 is divided into 8 equal groups and woven into pipa-shaped hanging rings 341 of the same size. The two sets of hanging rings 341 are then inserted into the corresponding fixing grooves at both ends of the hollow fixing member 352. The transmission trunk 33 of the multi-strand cable 31 is then passed through the hollow fixing member 352 and connected to the aviation plug 7. The transmission trunk 33 of the composite cable 32 is then passed through the hollow fixing member 352 from the other end and connected to the aviation plug 7, thus achieving the continuity of the transmission trunk 33. At the same time, a transmission branch 331 is led out from the branch end of the aviation plug 7 and passes through the preset outlet hole on the side wall of the hollow fixing member 352. After the wiring is completed, the two outer shells 351 are fastened together from both sides to the outside of the hollow fixing piece 352, and the fastening screws are tightened to complete the assembly.

[0064] like Figure 9As shown, the connection method of composite cables 32 is applied to the segmented connection of cables between two adjacent sets of working umbrellas 4 or power-consuming equipment in the middle of the umbrella ladder. During connection, the multi-strand load-bearing bundles 34 of the two composite cable sections 32 are divided into 8 groups and woven into pipa-shaped hanging rings 341. The hanging rings 341 of the two composite cable sections 32 are respectively inserted into the corresponding fixing grooves from both ends of the hollow fixing member 352. The transmission trunks 33 of the two composite cable sections 32 are respectively passed through both ends of the hollow fixing member 352 and connected to the internal aviation plug 7 to achieve continuous transmission trunks 33. At the same time, two transmission branches 331 are led out from the branch ends of the aviation plug 7, one extending downward to supply power to the adjacent upper drive power supply system 51, and the other extending upward to supply power to the adjacent lower drive power supply system 54.

[0065] Each composite cable 32 corresponds to a set of power umbrellas 4 and power umbrella energy replenishment devices 5. In this embodiment, the first composite cable 323 and the second composite cable 324 are respectively equipped with a set of power umbrellas 4 and power umbrella energy replenishment devices 5.

[0066] like Figure 10 As shown, the power umbrella energy replenishment device 5 includes an upper drive energy replenishment system 51, an upper driver 52, a lower driver 53, and a lower drive energy replenishment system 54, which are sequentially arranged along the composite cable 32. The lower drive energy replenishment system 54 and the upper drive energy replenishment system 51 are fixedly installed on the composite cable 32, and a set distance is maintained between them, which is the working stroke of the power umbrella 4. Both the lower driver 53 and the upper driver 52 can slide back and forth along the axial direction of the composite cable 32. The power umbrella 4 includes umbrella lines and an umbrella body. The center of the umbrella body is fixedly connected to the upper driver 52, and the umbrella lines are fixedly connected to the lower driver 53. The power umbrella 4 realizes the opening and closing action of the umbrella body through the movement of the upper driver 52 and the lower driver 53 and wind energy.

[0067] Both the upper drive energy replenishment system 51 and the lower drive energy replenishment system 54 integrate a step-down module, a charging module, and an energy storage battery. A photovoltaic energy replenishment system can be added to the outer casing 351 to provide auxiliary power. The step-down module converts the high-voltage power supply 11 transmitted by the conductive cable 21 into a working voltage matching the energy storage battery. The energy storage battery stores electrical energy for at least one operating cycle, and its capacity can be calculated based on the local wind speed intervals. The charging module is responsible for connecting to the upper drive 52 and the lower drive 53 to complete charging control and power transmission. The upper drive 52 and the lower drive 53, as the motion actuators of the working umbrella 4, are equipped with small-capacity batteries. The battery capacity is not less than twice the energy consumption of a single umbrella opening and closing operation. Under extreme conditions, only a single umbrella opening and closing operation needs to be maintained, eliminating the need for a large-capacity energy storage battery to cover the entire operating cycle.

[0068] During operation, the lower actuator 53 automatically connects to the charging circuit when it moves to the position of the lower drive power supply system 54, and remains connected to the lower drive power supply system 54 at all times except when the umbrella is closed. The upper actuator 52 remains continuously connected to the upper drive power supply system 51 during power generation, and the device battery is fully charged after each cycle of the working umbrella 4. Specifically, when the umbrella changes from an open state to a closed state: the lower actuator 53 is locked to the lower drive power supply system 54 through a locking mechanism, the umbrella ropes are tightened under the action of the wind, and the umbrella is in an open state; after the lower actuator 53 releases the lock between itself and the lower drive power supply system 54, the umbrella moves upward under the action of the wind; the umbrella ropes change from a taut state to a relaxed state, and the umbrella flips under the action of the wind, changing to a closed state. The umbrella changes from a closed state to an open state: the lower actuator 53 and the lower drive power supply system 54 are in a locked state, the parachute ropes are in a relaxed state, and the umbrella flips to a closed state; the upper actuator 52 and the lower actuator 53 move downward together along the composite cable 32, and the lower actuator 53 moves downward to the lower drive power supply system 54 and is locked by the locking mechanism; the upper actuator 52 moves upward along the composite cable 32, and the umbrella gradually opens under the action of wind, driving the upper actuator 52 to continue to move upward; after the umbrella is fully opened, the upper actuator 52 stops moving upward, the lower actuator 53 is locked to the lower drive power supply system 54 through the locking mechanism, and the umbrella is in an open state.

[0069] like Figure 11 As shown, the specific energy replenishment operation steps are as follows: For the upper drive power supply system 51 and the lower drive power supply system 54: the power supply cable structure 3 is retrieved by a ground winch. The first multi-strand cable 311 and the conductor cable are respectively equipped with aviation male and female connectors. The male or female connector at the upper end of the first multi-strand cable 311 is lowered to a height that can be connected to the male or female connector of the conductor cable. The aviation male and female connectors are connected. The corresponding switches are closed according to the steps to connect the conductive cable 21 and the transmission trunk 33. The ground power supply device transmits the boosted electrical energy to the transmission trunk 33 through the conductive cable 21. The electrical energy in the transmission trunk 33 passes through the transmission branches 331 at each connector 35, and then passes through the upper drive power supply system 51 and the lower drive power supply system 54 to step down the voltage. The stepped-down electrical energy is then transmitted to the upper drive 52 and the lower drive 53 for charging. After confirming that all upper drive power supply systems 51 and lower drive power supply systems 54 are fully charged, disconnect the power supply switch, confirm that the line is de-energized, unlock and disconnect the aviation plug 7; then start the ground winch to slowly release the power cable structure 3 to the working height and restore normal power generation operation.

[0070] For the upper driver 52 and the lower driver 53: Both the upper driver 52 and the lower driver 53 are equipped with small-capacity device batteries. When the upper driver 52 moves to and connects to the upper drive power supply system 51, the energy storage battery of the upper drive power supply system 51 charges the device battery of the upper driver 52. When the lower driver 53 moves to and connects to the lower drive power supply system 54, the energy storage battery of the lower drive power supply system 54 charges the device battery of the lower driver 53. Each cycle of the power umbrella 4 will fully charge the device battery.

[0071] If the number of power umbrella 4 equipment sets needs to be increased, simply remove the second multi-strand cable 312 or the first composite cable 323 on the existing basis, add the corresponding number of composite cables 32 and connectors 35, and then reconnect them. The adjustment is simple. If the installation height of the equipment needs to be adjusted, the lead-out length and fixed position of the transmission branch 331 can be adjusted accordingly to adapt to different equipment layout schemes. At the same time, the output voltage of the boost module 13 and the configuration capacity of the energy storage module 12 can be adjusted according to the changes in the total length of the power cable structure 3 and the total aerial load. When the cable length increases and the transmission distance becomes longer, the transmission voltage is appropriately increased to further reduce line loss. When the number of aerial equipment increases and the total power consumption increases, the energy storage capacity of the ground energy storage module 12 is increased accordingly to ensure the ability to replenish power and continue operation.

[0072] Based on the experimental data of this invention, and considering regional differences, the annual power generation hours range from 2000 to 4000 hours, calculated according to the cut-out / cut-in wind speeds. Generally, as long as the airborne power generation device is charged when the wind speed is lower than the cut-in wind speed or higher than the cut-out wind speed, it is sufficient to achieve power generation operation as long as the wind speed is higher than the cut-in wind speed.

[0073] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solutions of the present invention, and are not intended to limit the specific implementation of the present invention.
