Description

Technical Field

[0001] This disclosure relates to the technical field of power generation equipment, specifically to a high-altitude wind power generation system. Background Technology

[0002] Utilizing high-altitude wind energy for power generation is a common approach in wind power technology. Currently, the solution for high-altitude wind power generation involves constructing ground-based power stations and installing corresponding components such as winch mechanisms, energy conversion devices, and central control systems. However, this current approach to constructing high-altitude wind power systems suffers from problems such as long construction periods and poor flexibility, making it difficult to meet the diverse needs that may arise in actual operating conditions. Summary of the Invention

[0003] In view of this, the present disclosure aims to provide a high-altitude wind power generation system to solve the problems of long deployment and construction cycles and poor flexibility of current high-altitude wind power generation equipment.

[0004] This disclosure provides a high-altitude wind power generation system, including: The supporting base is an independent and transportable installation foundation; The hoisting mechanism includes a winch fixedly connected to the bearing base and a cable wound on the drum of the winch; An energy harvesting mechanism, connected to the cable, drives the cable to be released from the drum under the action of wind energy, thereby driving the drum to rotate. The energy conversion mechanism includes a motor connected to the drum of the winch, the motor being used to generate electrical energy under the drive of the drum and to drive the drum to rotate; An energy storage mechanism, electrically connected to the energy conversion mechanism, is used to store the electrical energy generated by the energy conversion mechanism; A converter, electrically connected to the energy storage mechanism, is used to perform mode conversion on the electrical energy flowing into and out of the energy storage mechanism; A constant tension winch, mounted on the supporting base, is used to transfer the cable between the drum and the constant tension winch at a set tension.

[0005] By setting the supporting base as an independent installation foundation for transportation, when using the power generation system, it is only necessary to transport the power generation system to a specific location. There is no longer a need to build fixed factory buildings or other structures at various locations. The power generation system can be put into operation simply by transporting it to the appropriate location and performing basic modulation work, achieving rapid deployment. Furthermore, by integrating the power generation system into the supporting base, the system can be transported as a whole to the required location, no longer relying on fixed sites. This is particularly beneficial for areas where traditional power grids are difficult to cover and construction costs are high, such as remote mountainous areas, islands, and disaster emergency sites. The power generation system using this embodiment can be conveniently deployed and used in these areas.

[0006] This solution fundamentally eliminates the need for on-site foundation pouring, installation of fixed bases, and complex connections between various subsystems. This allows the entire power generation system to be transported and positioned as a modular unit, thereby reducing the deployment cycle from several days or weeks in traditional solutions to hours. It also enables the system to be easily moved from one location to another, effectively solving the fundamental technical defects of traditional high-altitude wind power generation systems, which rely on permanent fixed infrastructure and suffer from inflexible deployment, inability to relocate, and limited applicability.

[0007] In one specific feasible implementation, the supporting base includes at least two sub-frame units, and a connection structure is provided between the sub-frame units, which are detachably connected through the connection structure. Each subframe unit carries at least a portion of the hoisting mechanism, energy capture mechanism, energy conversion mechanism, energy storage mechanism, converter, and constant tension winch.

[0008] In one specific feasible implementation, the subframe unit includes an installation platform and reinforcing columns fixedly connected to the installation platform; Interlocking connectors are provided between the reinforcing columns of different sub-frame units, and adjacent sub-frame units are connected by plugging in the connectors.

[0009] In one specific implementation scheme, the connector includes a plug-in post and a plug-in sleeve that fit together, the plug-in post and the plug-in sleeve being fixedly connected to the reinforcing column of the adjacent sub-frame unit respectively; The connector also includes bolts and fasteners for securing the plug pins and plug sleeves.

[0010] In one specific implementation, the connector further includes a connection terminal fixed to the plug post and the plug sleeve, and plugging in when the plug post and the plug sleeve are fixedly connected; The mechanisms installed on each sub-frame unit are electrically connected to the connection terminals on the sub-frame unit.

[0011] In one specific implementation scheme, the winch mechanism further includes a mounting frame, which is a frame structure and fixedly connected to a supporting frame. The winch is disposed within the mounting frame. The power generation system also includes a rope routing assembly disposed on the mounting frame. The rope routing assembly has a limiting channel for the cable to pass through. The limiting channel is configured to slide relative to the winch to adjust the position of the cable relative to the winch. The sliding direction of the limiting channel is parallel to the drum axis of the winch.

[0012] In one specific implementation, the rope assembly includes a limiting member slidably connected to the mounting frame and a driving member connected between the limiting member and the mounting frame, with a limiting channel located on the limiting member; The driving component causes the limiting component to slide relative to the mounting bracket.

[0013] In one specific implementation scheme, it also includes a universal pulley, which includes a base fixed relative to the support base, a bracket rotatably connected to the base, and a pulley rotatably connected to the bracket. The pulley is provided with a groove for winding the cable and preventing the cable from disengaging from the pulley.

[0014] In one specific implementation scheme, a lifting platform is provided on the upper side of the mounting frame, and the universal pulley is fixedly connected to the lifting platform; The lifting platform is equipped with guide pulleys on its lower side, which are used to guide the cable between the universal pulley and the rope assembly.

[0015] In one specific implementation scheme, a central control system is also included, which is connected to the hoisting mechanism, energy capture mechanism, energy conversion mechanism, energy storage mechanism, converter, and constant tension winch, and is used to receive data from each mechanism and control the actions of each mechanism.

Detailed Implementation

[0022] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure are within the scope of protection of this disclosure.

[0023] Current high-altitude wind power systems typically employ a fixed ground-based power station design. This approach requires extensive civil engineering work at a selected site, including foundation construction and power plant building. Core functional subsystems, such as the winch mechanism, energy conversion device, and central control system, are then permanently and dispersed across these fixed infrastructures. These subsystems are interconnected via pipelines laid on-site, forming an integrated system dependent on the specific site.

[0024] Because the aforementioned solutions inherently rely on permanent fixed installations and complex on-site construction, their deployment inevitably suffers from long cycles and poor flexibility. Once completed, the entire system is difficult to relocate to other locations for reuse. This makes it difficult for high-altitude wind power systems in related technologies to meet the demands for rapid deployment and mobile applications. Therefore, how to achieve rapid deployment and flexible relocation of high-altitude wind power systems, and significantly reduce their dependence on fixed infrastructure, has become a specific technical problem that urgently needs to be solved in this field.

[0025] To overcome the above problems, this disclosure provides a high-altitude wind power generation system that achieves flexible deployment of the power generation system by setting up a mobile, transportable independent unit as the installation base. The following detailed description, in conjunction with specific drawings and embodiments, further illustrates this system.

[0026] refer to Figure 1 and Figure 2 This illustration shows the main structure of a high-altitude wind power generation system provided in this embodiment, including a support base 10, a winch mechanism 20, an energy capture mechanism 30, an energy conversion mechanism 40, and an energy storage mechanism 50. The support base 10 is a transportable and transferable independent unit, serving as the rigid installation foundation for the power generation system. Exemplarily, in this embodiment, the support base 10 is a transportable steel frame; in other embodiments, the support base 10 may be a container-type frame. The winch mechanism 20, energy capture mechanism 30, energy conversion mechanism 40, and energy storage mechanism 50 are all fixedly connected to the support base, enabling the power generation system to function as a movable and transferable whole.

[0027] The power generation system of this disclosure generates electricity by capturing wind energy at high altitudes and converting it into electrical energy. The hoisting mechanism 20, energy capture mechanism 30, energy conversion mechanism 40, and energy storage mechanism 50 are integrated and mounted on the supporting base 10. The supporting base 10 is a transportable independent unit, so that the power generation system can be transported as a whole.

[0028] The energy harvesting mechanism 30 is connected to the hoisting mechanism 20. The hoisting mechanism 20 lifts the energy harvesting mechanism 30 to a high altitude and retracts it to the ground. Under the influence of wind energy at high altitudes, the energy harvesting mechanism 30 moves, which in turn rotates the winding structure of the hoisting mechanism 20. The energy conversion mechanism 40 is connected to the winding structure of the hoisting mechanism 20, converting the mechanical energy of the rotating hoisting mechanism 20 into electrical energy. The electrical energy generated by the energy conversion mechanism 40 is then transmitted to the energy storage mechanism 50 for storage.

[0029] In addition, the energy storage mechanism 50 is electrically connected to a converter 51, which performs mode conversion on the current input to and output from the energy storage mechanism 50. Specifically, the converter 51 has two sets of connection paths. One set of connection paths is used to transmit the electrical energy generated by the energy conversion mechanism 40 to the energy storage mechanism 50 for storage via the converter 51. The other set of connection paths is used to transmit the electrical energy stored in the energy storage mechanism 50 to electrical devices or upload it to the power grid. Specifically, when electrical energy is input into the energy storage mechanism 50, the converter 51 converts AC to DC. When electrical energy is output from the energy storage mechanism 50, the converter 51 converts DC to AC.

[0030] When using this power generation system, it is only necessary to transport it to a specific location, eliminating the need to build fixed factories or other structures at various locations. The system can be put into operation after simple modulation, enabling rapid deployment. Furthermore, by integrating the power generation system into the supporting substrate 10, it can be transported as a whole to the required location, no longer relying on fixed sites. This is particularly beneficial for areas where traditional power grids are difficult to cover and construction costs are high, such as remote mountainous areas, islands, and disaster emergency sites. The power generation system of this embodiment can be conveniently deployed and used in these areas.

[0031] This solution fundamentally eliminates the need for on-site foundation pouring, installation of fixed bases, and complex connections between various subsystems. This allows the entire power generation system to be transported and positioned as a modular unit, thereby reducing the deployment cycle from several days or weeks in traditional solutions to hours. It also enables the system to be easily moved from one location to another, effectively solving the fundamental technical defects of traditional high-altitude wind power generation systems, which rely on permanent fixed infrastructure and suffer from inflexible deployment, inability to relocate, and limited applicability.

[0032] The load-bearing base 10 can be constructed by welding or bolting high-strength steel sections (such as I-beams, channel steel, or square tubing) to form a three-dimensional frame structure with sufficient rigidity and load-bearing capacity. The bottom of this frame can be equipped with multiple support legs and leveling mechanisms (not shown in the figure), such as height-adjustable anchor bolts or hydraulic outriggers, to adapt to the flatness requirements of different sites. For ease of transportation, the bottom of the load-bearing base 10 can also integrate or have pre-reserved interfaces compatible with standard transport vehicles (such as flatbed trailers or container trailers), such as standard twist lock bases or tow pin holes.

[0033] refer to Figure 3 The supporting base 10 includes at least two sub-frame units 11, and a connection structure is provided between the different sub-frame units 11 to achieve a detachable and fixed connection between the different sub-frame units 11. Each sub-frame unit 11 carries at least a portion of the following structures: hoisting mechanism 20, energy capture mechanism 30, energy conversion mechanism 40, and energy storage mechanism 50.

[0034] In actual setup, the different mechanisms can be installed on corresponding sub-frame units 11 according to the tightness of their connection. For example, the hoisting mechanism 20 and the energy conversion mechanism 40 need to be directly connected to achieve energy conversion, and the connection between them is relatively complex; therefore, the hoisting mechanism 20 and the energy conversion mechanism 40 are fixed on the same sub-frame unit 11. Energy transmission between the energy storage mechanism 50 and the energy conversion mechanism 40 is more conveniently achieved through connections using transmission cables or similar devices; therefore, the energy storage mechanism 50 and the energy conversion mechanism 40 can be fixedly connected to different sub-frame units 11.

[0035] Thus, when the power generation system is transported to a specific location for wind energy capture and power generation, the multiple mechanisms on the same sub-frame unit 11 remain connected and do not need to be reconnected. It can be put into use directly by simply fixing the multiple sub-frame units 11 and connecting the mechanisms on different sub-frame units 11, which improves convenience.

[0036] refer to Figure 1 and Figure 3 The sub-frame unit 11 includes a mounting platform 111 and reinforcing columns 112. The reinforcing columns 112 are fixedly connected to the mounting platform 111. Exemplarily, the reinforcing columns 112 are located on the back of the mounting platform 111 to avoid occupying the mounting space on the mounting platform 111. The support base 10 also includes connectors 12, which are connected between the reinforcing columns 112 of different sub-frame units 11, so that different sub-frame units 11 are connected by plugging in the connectors 12.

[0037] Specifically, the connector 12 includes a plug-in post 121 and a plug-in sleeve 122, which are plugged into each other. The plug-in post 121 and the plug-in sleeve 122 are respectively fixedly connected to the reinforcing post 112 of the adjacent sub-frame unit 11. The connection of the reinforcing post 112, i.e. the sub-frame unit 11, is realized through the plug-in engagement of the plug-in post 121 and the plug-in sleeve 122.

[0038] In addition, the connector 12 also includes bolt fasteners, which are used to fix the connector post 121 and the connector sleeve 122, thereby improving the firmness of the fixed connection of the subframe unit 11.

[0039] For example, the plug-in post 121 and the plug-in tube 122 are both fixed on the side wall at the end of the corresponding reinforcing post 112. When the sub-frame unit 11 is fixedly connected, the plug-in post 121 is inserted into the plug-in tube 122 and fixed by bolt fasteners 123. At this time, the reinforcing post 112 is in the connected state.

[0040] In other embodiments, the plug-in post 121 and the plug-in tube 122 may be fixedly connected to the end wall of the corresponding reinforcing post 112.

[0041] refer to Figure 4 The plug-in post 121 and plug-in cylinder 122 are provided with connection terminals 13. The connection terminals 13 are electrically connected to the mechanisms fixedly connected to each sub-frame unit 11. When multiple sub-frame units 11 are fixedly connected, the connection terminals 13 on adjacent sub-frame units 11 are plugged into each other, thereby realizing the electrical connection and signal transmission of the various mechanisms on different sub-frame units 11. It should be noted that the connection terminals 13 on the plug-in post 121 and plug-in cylinder 122 are plugged into each other. The specific structure can be referred to the female plug conventionally used in related fields. The specific structure will not be described in detail in this embodiment.

[0042] By using the connection terminals 13, each mechanism is first electrically connected to the connection terminals 13 on its respective sub-frame unit 11, forming a modular structure for the entire power generation system, which facilitates subsequent assembly. After transporting the sub-frame units 11 to the workplace, only the individual sub-frame units 11 need to be fixedly connected. Simultaneously with fixing the sub-frame units 11, the connection terminals 13 are plugged in, achieving electrical connection between multiple mechanisms. This eliminates the need for on-site connection operations for multiple mechanisms, significantly improving the efficiency of assembling the power generation system at the workplace.

[0043] refer to Figure 1 and Figure 2 The hoisting mechanism 20 is fixedly connected to the supporting base 10, and the energy capture mechanism 30 is connected to the hoisting mechanism 20. In the process of collecting wind energy in the high altitude for power generation, the energy capture mechanism 30 needs to be released to the high altitude to collect wind energy in the high altitude. The energy capture mechanism 30 is released or recovered through the hoisting mechanism 20.

[0044] The energy conversion mechanism 40 is connected to the hoisting mechanism 20. The energy capture mechanism 30 collects wind energy at high altitude and converts the collected wind energy into kinetic energy through the energy capture mechanism 30 and the hoisting mechanism 20. The energy conversion mechanism 40 is connected to the hoisting mechanism 20 and converts the kinetic energy of the hoisting mechanism 20 into electrical energy.

[0045] For example, refer to Figure 1 and Figure 2 The winch mechanism 20 includes a winch 21 fixedly connected to the supporting base 10 and a cable 22 wound around the winch 21. An energy harvesting mechanism 30 is connected to the cable 22. During operation, the energy harvesting mechanism 30 is positioned within a certain altitude range at high altitudes. Under the influence of wind energy, it drives the cable 22 to move, which in turn drives the winch 21 to capture wind energy at high altitudes and convert it into the mechanical energy of the winch 21.

[0046] For example, the energy capture mechanism 30 includes a buoyancy carrier 31 and a capture umbrella 32 connected to the cable 22. The buoyancy carrier 31 is fixedly connected to the free end of the cable 22, and the buoyancy generated by the buoyancy carrier 31 drives the free end of the cable 22 and the capture umbrella 32 fixed to the cable 22 to rise. Optionally, the buoyancy carrier 31 is a helium balloon.

[0047] Multiple capture umbrellas 32 are provided and fixed at intervals along the length of the cable 22. Each capture umbrella 32 is equipped with a power element 33, which drives the capture umbrella 32 to switch between two states: an unfolded state and a retracted state.

[0048] The specific process of the energy capture mechanism 30 capturing high-altitude wind energy is as follows: The cable 22 is wound around the winch 21, and the buoyancy carrier 31 is fixedly connected to the free end of the cable 22. Under the buoyancy of the buoyancy carrier 31, the cable 22 is pulled out from the winch 21, and as the cable 22 is pulled out, multiple capture umbrellas 32 are sequentially fixed to the pulled-out cable 22. Alternatively, the cable 22 can be pulled out from the winch 21 to a certain length at the beginning, and then the buoyancy carrier 31 and multiple capture umbrellas 32 are fixed to the cable 22.

[0049] Then, the buoyancy of the buoyancy carrier 31 drives the cable 22 and the capture umbrella 32 to rise until they reach a predetermined altitude range, exemplarily between 500 meters and 2000 meters, preferably between 1000 meters and 2000 meters. This altitude range is an area with high wind energy density at high altitudes, and avoids low-altitude turbulence, ensuring the wind speed in the area. However, if the altitude is too high, the cable 22 will become too heavy, increasing cost and control difficulty.

[0050] After the buoyancy carrier 31 drives the cable 22 and the capture umbrella 32 to a height of 1000 meters, the control power element 33 opens the capture umbrella 32. In this way, the wind energy acts on the capture umbrella 32, which in turn drives the cable 22 to continue to be released from the winch 21. Through the rotation of the shaft of the winch 21, the wind energy at high altitude is captured and converted into the mechanical energy of the winch 21.

[0051] In addition, the power generation system also includes a constant tension winch 80, which is fixedly connected to the support base 10 and used to transfer the cable 22 between the winch 21 and the constant tension winch 80 at a set tension. Specifically, the cable 22 is wound around the constant tension winch 80, and the cable 22 is transferred to the winch 21, or the cable 22 wound on the winch 21 is transferred to the constant tension winch 80. In this way, the constant tension winch 80 ensures that the cable 22 wound on the winch 21 maintains a set and constant tension, thus avoiding the problem of the cable 22 becoming tangled on the winch 21.

[0052] With the converter 51 and constant tension winch 80 provided, each subframe unit 11 carries at least a portion of the hoisting mechanism 20, energy capture mechanism 30, energy conversion mechanism 40, energy storage mechanism 50, converter 51, and constant tension winch 80.

[0053] refer to Figure 1 and 2 The energy conversion mechanism 40 includes a motor 41, which is connected to the shaft of the winch 21. Exemplarily, the shafts of the motor 41 and the winch 21 are connected via a gear set. During power generation, the motor 41 acts as a generator, and the cable 22 drives the shaft of the winch 21 to rotate, thereby driving the motor 41 to operate and generate electricity. During the cable 22 retraction phase, the motor 41 acts as a motor, driving the winch 21 to operate and retract the cable 22.

[0054] Furthermore, the energy storage mechanism 50 is electrically connected to the motor 41, and the electrical energy generated by the motor 41 is stored in the energy storage mechanism 50. The energy storage mechanism 50 is used for the storage, buffering, and smooth release of electrical energy to cope with fluctuating power generation and load demands. Its specific type can be flexibly selected or combined according to the application scenario: lithium-ion battery packs (such as lithium iron phosphate batteries) with high energy density and suitable for medium- and long-term energy storage; supercapacitor arrays with extremely high power density and extremely fast response speed, which are good at smoothing second-level power fluctuations; and flywheel energy storage devices that store energy in the form of kinetic energy and are suitable for high-frequency cycling. In addition, long-term energy storage systems such as hydrogen energy storage can also be configured. These energy storage devices are centrally controlled by the central control system 60 and can be used individually or in combination to ensure the continuity and stability of power supply in off-grid, weak grid, or emergency scenarios.

[0055] refer to Figure 1 and Figure 5 The power generation system also includes a central control system 60, which is responsible for monitoring and adjusting the operating status of the entire power generation system, including parameters such as cable tension, cable release length, motor speed, and voltage and current output by motor 41 to energy storage mechanism 50, so as to achieve a stable power generation process.

[0056] In one embodiment of this disclosure, the central control system 60 is responsible for coordinating all automated operations of the entire power generation system. It is responsible for data acquisition, status monitoring, and generating advanced control commands (such as starting and stopping power generation cycles and managing energy dispatch), and, based on these commands, directly controls the precise movements of actuators such as the winch 21 and the energy conversion mechanism 40.

[0057] Specifically, the central control system 60 is signal-connected to the winch 21 to control the speed and length of the release cable 22; in addition, in order to detect the tension of the cable 22, a series tension sensor can be connected to the force path of the cable 22 and signal-connected to the central control system 60, so as to realize the detection of the tension of the cable 22.

[0058] Furthermore, the power element 33 is also connected to the central control system 60 to obtain the opening angle of the capture umbrella 32 controlled by the power element 33. It can control the power element 33 to open or close the capture umbrella 32, and adjust the opening angle of the capture umbrella 32 to ensure efficient wind energy capture and reduce the phenomenon of excessive tension on the cable 22 caused by excessive wind energy acting on the capture umbrella 32, thus reducing the problem of damage due to excessive cable tension. In addition, adjusting the opening angle of the capture umbrella 32 can improve the stability of wind energy capture efficiency, which is beneficial to ensuring the stability of subsequent power generation by the winch 21 driving the motor 41.

[0059] For example, converter 51 is signal-connected to central control system 60 so that central control system 60 controls converter 51 to convert current. Constant tension winch 80 is signal-connected to central control system 60 so that central control system 60 adjusts the power of constant tension winch 80 according to the tension of cable 22 between constant tension winch 80 and winch 21 to maintain stable tension of cable 22 between constant tension winch 80 and winch 21.

[0060] It should be noted that, in actual configuration, the central control system 60 can also be connected to other components via signals according to actual needs, so that the central control system 60 can obtain relevant information and control the corresponding components to perform corresponding actions based on the obtained information. This will not be described in detail in this embodiment.

[0061] refer to Figure 1 and Figure 2 The power generation system also includes an adjustment mechanism 70, which is used to adjust the attitude of the cable 22. Specifically, the adjustment mechanism 70 includes a universal pulley 71 for guiding the outgoing direction of the cable 22. The universal pulley 71 includes a base 711, a bracket 712, and a pulley 713. The base 711 is fixedly connected to the supporting base 10, the bracket 712 is rotatably connected to the base 711, and the pulley 713 is rotatably connected to the bracket 712.

[0062] For example, the energy conversion mechanism 40 also includes a mounting frame 42, a motor 41 fixedly connected inside the mounting frame 42, the mounting frame 42 and the support base 10 fixedly connected, and a base 711 fixedly connected to the mounting frame 42.

[0063] The portion of cable 22 released from winch 21 passes through pulley 713 and extends into the air. During the operation of the power generation system, the supporting base 10 remains fixed, while the energy capture mechanism 30 may tilt in different directions depending on the wind direction. Specifically, when determining the placement position and angle of the supporting base 10, the influence of wind direction is considered, and the angle of the supporting base 10 is chosen to facilitate the release of cable 22. During subsequent continuous power generation, factors such as changes in wind direction and differences in wind direction at low and high altitudes may cause certain changes in the direction of cable 22. The universal pulley 71 can accommodate different release directions of cable 22, ensuring smooth cable retrieval and release.

[0064] refer to Figure 1 and Figure 2 The winch mechanism 20 also includes a mounting frame 23, which, exemplarily, is a frame structure welded from structural steel. The winch 21 is installed inside the mounting frame 23, and the drum of the winch 21 is rotatably connected to the mounting frame 23. The adjustment mechanism 70 also includes a rope arrangement assembly 72, which is disposed on the mounting frame 23 and located above the winch 21.

[0065] The rope winding assembly 72 includes a limiting member 721 and a driving member 722. The limiting member 721 is slidably connected to the mounting frame 23, and the direction of sliding of the limiting member 721 relative to the mounting frame 23 is parallel to the axis of the drum of the winch 21. The driving member 722 is connected between the mounting frame 23 and the limiting member 721, and drives the limiting member 721 to slide relative to the mounting frame 23. The limiting member 721 is provided with a limiting channel through which the cable 22 passes. During the process of winding the cable 22 onto the drum and releasing it from the drum, the relative position of the cable 22 and the drum is adjusted as the limiting member 721 slides. This ensures that the cable 22 is tightly and orderly wound in layers on the drum of the winch 21, preventing problems such as tangled ropes and overlapping.

[0066] refer to Figure 5 The drive component 722 can also be connected to the central control system 60 via signal connection, so that the position of the limit component 721 can be adjusted in real time through the central control system 60.

[0067] For example, the limiting member 721 is a fixed pulley, and the driving member 722 is a screw-slider structure. The driving member 722 includes a screw rotatably connected to the mounting frame 23 and a slider threadedly connected to the screw, with the limiting member 721 fixedly connected to the slider. Additionally, the slider is slidably connected to the mounting frame 23, restricting its rotation relative to the mounting frame 23. Specifically, a guide rod is fixedly connected to the mounting frame 23, and a through hole is provided on the slider for the guide rod to pass through. The guide rod passes through the through hole to achieve a slidable connection with the slider, the guide rod, and the mounting frame 23. Furthermore, the driving member 722 also includes a servo motor fixedly connected to the mounting frame 23. The output shaft of the servo motor is connected to the screw, driving the screw to rotate, thereby causing the slider to slide relative to the mounting frame 23, adjusting the position of the limiting member 721, and thus adjusting the position of the cable 22 wound on the winch 21 to ensure the neatness of the cable 22 wound on the winch 21.

[0068] In other embodiments, the drive element 722 may be configured as a linear drive structure such as a cylinder, electric actuator, or hydraulic cylinder. Furthermore, refer to... Figure 2 A lifting platform 43 is mounted on the mounting frame 23, and universal casters 71 are fixedly mounted on the lifting platform 43. Exemplarily, interlocking guide cylinders are provided between the lifting platform 43 and the mounting frame 42 to limit the sliding direction of the lifting platform 43 relative to the mounting frame 42, ensuring the stability of the sliding of the lifting platform 43 relative to the mounting frame 42. In addition, an electric push rod is fixedly connected to the mounting frame 42, and the telescopic end of the electric push rod is fixedly connected to the lifting platform 43 to realize the function of raising and lowering the lifting platform 43 by extending and retracting the electric push rod.

[0069] In addition, a guide pulley 25 is installed on the lower side of the lifting platform 43. The guide pulley 25 is used to guide the cable between the universal pulley 71 and the rope arrangement assembly 72. Specifically, the lifting platform 43 has a through hole for the cable 22 to pass through. The cable 22 passes through the through hole, with one side extending through the universal pulley 71 and the other side extending through the rope arrangement assembly 72, thereby guiding the section of the cable 22 between the universal pulley 71 and the rope arrangement assembly 72.

[0070] The position of the omnidirectional pulley 71 can be adjusted by the lifting platform 43. Operators can then control the lifting platform 43 and observe the suspension status and angle of the cable 22 in real time to adjust the rope exit point of the omnidirectional pulley 71 to the optimal matching height with the position of the winch mechanism's 20 rows of ropes and the expected flight direction of the aerial equipment. This fundamentally reduces the requirement for absolute flatness of the site and eliminates complex initial positioning calculations, shortening deployment and commissioning time from several hours to tens of minutes.

[0071] During operation, the direction of force on cable 22 and the wrap angle between cable 22 and omnidirectional pulley 71 will dynamically change with the flight altitude of the aerial equipment (i.e., energy harvesting mechanism 30) and wind direction. If the height of omnidirectional pulley 71 is fixed, it may lead to accelerated wear of cable 22 or the risk of cable detachment under certain working conditions.

[0072] A universal pulley 71 is installed on the lifting platform 43. The height of the universal pulley 71 can be fine-tuned by the central control system 60 based on real-time operating data (such as cable tension and the angle at which the cable exits through the universal pulley), thereby dynamically optimizing the guide angle and wrap angle of the cable 22. This effectively reduces abnormal wear between the cable and the universal pulley 71, ensuring that the cable 22 always maintains a stable fit with the universal pulley 71, and improving the reliability, safety, and service life of the transmission system.

[0073] Furthermore, after transportation, the power generation system may experience minor stress deformation or settlement in structures such as the mounting frame 42, and the deployment site may be uneven or non-ideal ground. If the universal pulley 71 is fixed, it can easily cause the cable 22 to deviate. By setting up a lifting platform 43 to adjust the height of the universal pulley 71, installation errors caused by slight deformation of the mounting frame 42 or uneven ground can be compensated for, ensuring the accuracy of cable 22 guidance. This allows the power generation system to adapt to different working environments and achieves higher operational stability.

[0074] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications or equivalent substitutions made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
