Description

Technical Field

[0001] This disclosure relates to the field of high-altitude wind energy technology, specifically to a drive device and a high-altitude wind energy power generation system. Background Technology

[0002] High-altitude wind energy generally refers to wind energy at altitudes above 300 meters. The average wind speed increases with altitude. As a clean and renewable energy source, high-altitude wind energy is gaining increasing attention from various countries due to its high stability and low power generation costs. High-altitude wind energy conversion systems are key equipment for utilizing high-altitude wind energy.

[0003] The umbrella-shaped high-altitude wind energy system described in patent application number 200910190150.2 includes a main cable guided by a helium balloon or similar device. At least one working umbrella is mounted on the main cable, and each umbrella comprises two actuators, one upper and one lower, capable of moving freely along the main cable. The upper actuator moves the umbrella top up and down along the main cable. The umbrella's circumference is connected to the lower actuator via several parachute lines. The lower actuator is associated with a ferrule fixed to the main cable and can be controlled to connect and disconnect from the ferrule. When the umbrella opens, the lower actuator connects to the ferrule, and the high-altitude wind force on the umbrella surface is transmitted to the lower actuator via the parachute lines, then to the main cable via the ferrule, which in turn pulls the ground system to perform work or generate electricity. When the aerial system reaches its maximum altitude, the system controls the umbrella to close. At this point, the lower actuator separates from the ferrule and quickly ascends a short distance. The working umbrella then folds due to the wind, while the upper actuator descends and pushes the lower actuator to reconnect with the ferrule. The ground system then lowers the aerial module to its minimum altitude. Next, the upper drive ascends along the main cable to the predetermined position, and the system opens the parachute again.

[0004] In the umbrella-ladder combined high-altitude wind power generation technology, the upper and lower drives are quite heavy and need to repeatedly and rapidly move along the main cable to accurately reach and stop at predetermined positions. Therefore, climbing-belt or friction-based walking methods are generally used. These drive and walking methods not only consume a lot of energy, posing a significant challenge to the system's endurance, but also cause considerable wear and tear on the main cable, affecting the long-term reliability of the system. Utility Model Content

[0005] The purpose of this disclosure is to solve at least one of the above-mentioned technical problems.

[0006] Based on this, the following technical solution is adopted in this disclosure:

[0007] A driving device for driving a power umbrella in a high-altitude wind energy power system includes a first driver, a second driver, a first walking mechanism, a second walking mechanism, and a driving rope.

[0008] The first driver and the second driver are fixedly mounted on the main cable, which passes through the top of the working umbrella and is connected at one end to the air guidance and balancing module and at the other end to the ground module.

[0009] The first driver and the second driver jointly pull a drive rope parallel to the main cable, and the drive rope is equipped with a traction element;

[0010] The first walking mechanism is located at the top of the umbrella and can move up and down along the main cable; the second walking mechanism is connected to the circumference of the working umbrella through several umbrella circumference ropes and can move up and down along the main cable.

[0011] The main cable is also provided with a limiting mechanism for restricting the movement of the second traveling mechanism.

[0012] The first driver and the second driver are respectively provided with a winding and releasing mechanism for winding and releasing the driving rope. When the driving rope is pulled, the traction member drives the first walking mechanism or the second walking mechanism to walk along the main cable under the pull of the driving rope.

[0013] Preferably, the top of the working umbrella is connected to the first walking mechanism via several umbrella top ropes.

[0014] Preferably, the first walking mechanism and the second walking mechanism are respectively mounted on the main cable, and the first walking mechanism and the second walking mechanism include a sliding walking part for walking along the main cable.

[0015] More preferably, the first walking mechanism and the second walking mechanism further include a circumferential rotating mechanism, which is capable of rotating around the circumference of the first walking mechanism and the second walking mechanism;

[0016] The umbrella top cords are connected to the circumferential rotation mechanism of the first walking mechanism, and the umbrella circumferential cords are connected to the circumferential rotation mechanism of the second walking mechanism.

[0017] Preferably, the limiting mechanism restricts the movement of the second walking mechanism by means of a card.

[0018] Preferably, the traction member includes a first stop and a second stop, the first stop being located above the first traveling mechanism, and the second stop being located between the first traveling mechanism and the second traveling mechanism; or

[0019] The traction component includes a first stop, a second stop, and a third stop. The first stop is located above the first traveling mechanism, the second stop is located between the first traveling mechanism and the second traveling mechanism, and the third stop is located between the second stop and the first traveling mechanism.

[0020] More preferably, the first stop, the second stop, and the third stop can slide freely relative to the main cable under the pull of the drive rope;

[0021] The first stop and the third stop push the first walking mechanism to slide freely along the main cable, and the second stop pushes the second walking mechanism to slide freely along the main cable.

[0022] More preferably, the drive rope located between the first stop and the second stop is replaced by a sliding tube, which is fitted over the main cable, allowing the first traveling mechanism to slide along the sliding tube; one end of the sliding tube is connected to the first stop, and the other end is connected to the second stop; when the third stop is provided, the third stop is fixedly disposed on the outside of the sliding tube; or

[0023] The drive rope located between the first stop and the second stop is replaced by a rope cage, which includes a plurality of single ropes. Each single rope is evenly distributed around the main cable and passes through the first traveling mechanism. One end of each single rope is connected to the first stop and the other end is connected to the second stop. When the third stop is provided, the third stop is fixedly installed on the rope cage.

[0024] This disclosure also provides the following technical solutions:

[0025] A high-altitude wind energy utilization system, the system comprising the drive device described in any of the preceding descriptions.

[0026] Preferably, the system includes a plurality of the power umbrellas and a drive device that cooperates with each of the power umbrellas.

[0027] The technical solution claimed in this disclosure achieves the following beneficial effects:

[0028] 1) Two actuators are fixedly mounted on the main cable, and the drive cable is pulled by the actuators. Then, the walking mechanism is driven to walk on the main cable by the traction member fixed on the drive cable. The necessary walking part and the fixed part of the air control system are separated, which can effectively reduce the weight of the walking device and reduce the driving energy consumption.

[0029] Furthermore, since the energy-consuming devices are fixed relative to the main cable and do not move with the traveling mechanism, it is easier to achieve recharging and extended operation. For example, small wind turbines or solar power devices fixed to the main cable near the traction mechanism can be used to recharge the drive and other electrical equipment to meet the requirements of long-term operation.

[0030] 2) By adopting a free-sliding walking mechanism instead of a climbing or friction-based walking mechanism, wear on the main cable can be greatly reduced, extending the cable's service life while enhancing safety and reliability. Furthermore, the system structure is simplified and easier to control and maintain by using a drive rope to control the sliding blocks that propel the walking mechanism.

[0031] 3) By installing multiple sets of working umbrellas on the main cable and a dual drive mechanism that works in conjunction with them, the effect of an umbrella ladder can be achieved. The number of working umbrellas that open can be freely controlled according to the wind conditions in the air and the needs of ground work or power generation, so as to achieve the multiplication and flexible adjustment of output power.

[0032] 4) The drive rope between the first and second stops can be replaced with a slide tube or a rope cage depending on the actual working conditions. The slide tube maintains a stable fit between the stop and the traveling mechanism in both open and closed umbrella modes, significantly eliminating the tilting effect caused by unilateral force on the stop. It also effectively reduces the risk of entanglement between the drive rope and the main cable. Furthermore, because the elastic deformation of the slide tube is less than that of the drive rope, using a slide tube helps reduce the actual traction control length and control error of the actuator. In addition to the advantages of the slide tube, the rope cage offers better flexibility, making it more suitable for operation during the ascent phase. Moreover, its lighter weight results in lower system drive energy consumption. Attached Figure Description

Detailed Implementation

[0047] To make the objectives, technical solutions, and beneficial effects of the embodiments in this disclosure clearer, the technical solutions in 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, not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0048] Example 1

[0049] This embodiment provides a driving device for driving the power umbrella in a high-altitude wind power system.

[0050] The driving device in this embodiment includes a first driver, a second driver, a first walking mechanism, a second walking mechanism, and a driving rope. The first driver and the second driver are fixedly mounted on the main cable, which passes through the top of the working umbrella and is connected at one end to the air guidance and balancing module and at the other end to the ground module. The first driver and the second driver jointly pull a driving rope parallel to the main cable, and the driving rope is equipped with a traction element.

[0051] The first walking mechanism is located at the top of the umbrella and can move up and down along the main cable. The second walking mechanism is connected to the circumference of the working umbrella through several circumferential cables and can also move up and down along the main cable. The main cable is also equipped with a limiting mechanism to restrict the movement of the second walking mechanism.

[0052] The first and second drivers are respectively equipped with mechanisms for winding and releasing the drive rope. When the drive rope is pulled, the traction member drives the first or second traveling mechanism to travel along the main cable under the pull of the drive rope. In a preferred embodiment, the traction member includes a first stop and a second stop; the first stop is located above the first traveling mechanism, and the second stop is located between the first and second traveling mechanisms.

[0053] In a more preferred embodiment, a third stop can be provided on the drive rope, located between the second stop and the first traveling mechanism. The first, second, and third stops can slide freely along the main cable under the pull of the drive rope, thereby propelling either the first or second traveling mechanism to slide freely along the main cable. Specifically, the first and third stops propel the first traveling mechanism to slide freely along the main cable, while the second stop propels the second traveling mechanism to slide freely along the main cable.

[0054] In a preferred embodiment, the top of the working umbrella is connected to the first traveling mechanism via several umbrella top lines. The first and second traveling mechanisms are respectively mounted on the main cable, and both mechanisms include sliding travel sections for traveling along the main cable.

[0055] The first and second traveling mechanisms also include a circumferential rotating mechanism, which can rotate around the circumference of both mechanisms. The umbrella top cords are connected to the circumferential rotating mechanism of the first traveling mechanism, and the umbrella circumference cords are connected to the circumferential rotating mechanism of the second traveling mechanism.

[0056] In the preferred embodiment, the limiting mechanism restricts the movement of the second walking mechanism by means of a card.

[0057] In a more preferred embodiment, the drive rope located between the first and second stops is replaced by a sliding tube, which is fitted over the main cable, allowing the first traveling mechanism to slide along it. One end of the sliding tube is connected to the first stop, and the other end is connected to the second stop. When a third stop is provided, it is fixedly mounted on the outside of the sliding tube. Alternatively, the drive rope located between the first and second stops is replaced by a rope cage, which comprises several individual ropes evenly distributed around the main cable and passing through the first traveling mechanism. One end of each individual rope is connected to the first stop, and the other end is connected to the second stop. When a third stop is provided, it is mounted on the rope cage.

[0058] Example 2

[0059] Reference Appendix Figures 1 to 5 This embodiment provides a high-altitude wind energy power generation system that includes the drive device in Embodiment 1.

[0060] The high-altitude wind power generation system in this embodiment mainly consists of a ground module, a main cable 200, and a power generation umbrella 600. One end of the main cable 200 is connected to the aerial guidance and balancing module 100, and the other end is connected to the ground module, such as a ground power generation or power generation device.

[0061] The aerial guidance and balancing module 100 can be composed of devices such as helium balloons, airships, or balancing parachutes, with the main traction cable 200 at its lower part. The main functions of the aerial guidance and balancing module 100 are: to provide initial lift during the initial stage of system ascent; and to guide the aerial system to maintain a suitable angle of attack during subsequent operational phases. The main traction cable 200 serves as the mounting carrier for all other aerial equipment. When stressed, the main traction cable 200 pulls ground equipment to perform work or generate electricity. In recovery or reset mode, the main traction cable 200 uses a ground winch to pull the aerial system back to the ground or to a preset lower altitude.

[0062] The main cable 200 passes through the top opening of the working umbrella 600. Several top parachute ropes (not shown in the attached diagram) are evenly attached to the edge of the top opening of the working umbrella 600. The other end of the top parachute ropes is connected to the first traveling mechanism 500. The first traveling mechanism 500 can slide freely up and down along the main cable 200, meaning it can drive the top of the working umbrella 600 to move along the main cable 200. The circumference of the working umbrella 600 is connected to the second traveling mechanism 510 via several circumferential parachute ropes 610. The second traveling mechanism 510 can slide freely up and down along the main cable 200. The main cable 200 is also equipped with a limiting mechanism to restrict the movement of the second traveling mechanism 510.

[0063] At appropriate positions on the main cable 200, a first driver 300 and a second driver 310 are fixedly installed, with the second driver 310 installed below the first driver 300. The first driver 300 and the second driver 310 work together to pull a drive rope 700 arranged parallel to the main cable 200. The drive rope 700 is equipped with a traction member, and the first driver 300 and the second driver 310 are respectively equipped with a winding and unwinding mechanism (such as a small winch) for winding and unwinding the drive rope 700. When the drive rope 700 is pulled, the traction member drives the first traveling mechanism 500 or the second traveling mechanism 510 to slide along the main cable 200 under the pull of the drive rope 700.

[0064] In a preferred embodiment, a first stop block 400, a third stop block 420, and a second stop block 410 are fixedly installed at appropriate positions on the drive rope 700, from top to bottom, as traction components. The first stop block 400 is located above the first traveling mechanism 500, the second stop block 410 is located between the first and second traveling mechanisms 500, and the third stop block 420 is located between the second stop block 410 and the first traveling mechanism 500. All three stops can slide freely up and down synchronously along the main cable 200 under the traction of the drive rope 700. The first traveling mechanism 500, pushed by the first stop block 400 or the third stop block 420, can slide freely down or up along the main cable 200, while the second traveling mechanism 510, pushed by the second stop block 410, can slide downwards.

[0065] In a preferred embodiment, the first traveling mechanism 500 and the second traveling mechanism 510 are respectively mounted on the main cable 200. Each traveling mechanism includes a sliding traveling section and a circumferential rotating mechanism. The sliding traveling section is used to travel along the main cable 200. The top paracord of the working umbrella 600 is evenly attached to the circumferential rotating mechanism of the first traveling mechanism 500, while the perimeter paracords 610 are evenly attached to the circumferential rotating mechanism of the second traveling mechanism 510. Simultaneously, the drive rope 700 passes through the non-rotating portions inside both the first and second traveling mechanisms 500. This preferred design completely avoids the problem of the drive rope 700 entangled with the top and perimeter paracords 610.

[0066] In a preferred embodiment, the limiting mechanism restricts the movement of the second walking mechanism 510 by means of a locking mechanism. In an exemplary structure, a locking sleeve 800 is fixedly installed on the main cable 200 at an appropriate position above the second drive 310, and a locking head is provided below the second walking mechanism 510, which can be controlled to connect or disconnect from the locking sleeve 800.

[0067] In this embodiment, when the umbrella is open, the locking head and the locking sleeve 800 below the second walking mechanism 510 are connected. The working umbrella 600, acting as the windward side, captures the immense wind force and transmits it to the second walking mechanism 510 via the umbrella lines 610. This force is then transmitted to the main cable 200 through the locking head and locking sleeve 800 connector, causing the main cable 200 to drive ground equipment to perform work or generate electricity. For specific details, please refer to... Figure 1 As shown.

[0068] When the air-guided balancing module 100 reaches the preset altitude limit, the system will switch to parachute-closed mode. In parachute-closed mode, the clasp 800 receives the parachute-close command from the ground module and immediately disconnects the mechanical connection with the clasp of the second travel mechanism 510. The second travel mechanism 510 will rapidly ascend under the tension of the parachute lines, reaching the position of the second stop 410. At the same time, the working parachute 600, no longer restrained by the parachute lines 610, will rapidly fold under the influence of the wind, thus losing its wind-catching ability. (Reference to the state at the moment of parachute closure completion) Figure 2 As shown.

[0069] Next, the system switches to reset mode. In reset mode, the first actuator 300 and the second actuator 310 work together to pull down the drive rope 700 according to the reset command. The first actuator 300 is in release mode, and the second actuator 310 is in retraction mode. At this time, the first stop block 400 slides down the main cable 200 following the drive rope 700, pushing the first traveling mechanism 500 to move the umbrella top down synchronously on the main cable 200. Simultaneously, the second stop block 410 also pushes the second traveling mechanism 510 down the main cable 200 until the second traveling mechanism 510 reaches the position of the retaining sleeve 800 and reconnects and locks with it. The reset process is then complete.

[0070] Figure 3 The diagram illustrates the reset process. Throughout the reset, the canopy of the power parachute 600 remains folded, allowing the second actuator 310 to reset the second traveling mechanism 510 with minimal power consumption. In reset mode, the ground winch mechanism, with the parachute closed, consumes only a small amount of energy to simultaneously pull the entire aerial system back to the preset lower altitude limit.

[0071] Next, the system will switch back to the parachute opening mode. In this mode, the first actuator 300 and the second actuator 310 work together to pull the drive rope 700 upwards according to the opening command. The first actuator 300 is in rope-retracting mode, and the second actuator 310 is in rope-releasing mode. At this time, the third stop 420 will slide upwards on the main cable 200 following the drive rope 700, and after sliding a certain distance, it will push the first traveling mechanism 500 to move the parachute top upwards synchronously on the main cable 200. As the parachute top rises, the working parachute 600 will gradually return from its folded state to its normal state, creating a certain windward space inside. Then, driven by the wind, the working parachute will quickly open, assisting in pushing the parachute top to the designated opening position. The opening process is now complete. Figure 4 The diagram shows the opening process. Next, the working umbrella 600 will capture the wind force in the air again and transmit it to the main cable 200 through the umbrella ropes 610, the second walking mechanism 510, and the ferrule 800. The main cable 200 will then pull the ground equipment to perform work or generate electricity.

[0072] In the preferred embodiment, to increase output power, the windward area of ​​the canopy can be increased as much as possible while ensuring the material strength of the canopy fabric and ropes and the driving capability of the actuator. At the same wind speed, the system output power is directly proportional to the effective windward area of ​​the canopy.

[0073] In a more optimized design, to increase and flexibly adjust the system's output power, multiple sets of power umbrellas and their corresponding drive devices can be installed on the main cable 200, forming a parachute ladder assembly. Each power umbrella in the ladder assembly can be flexibly opened and closed according to wind conditions and ground-based power generation / work demands, achieving a multiplication and flexible adjustment of output power. An example of the parachute ladder assembly built using this design is provided for reference. Figure 5 As shown, two or more drive and power umbrella modules are installed at appropriate intervals on the main cable 200.

[0074] In addition, the aerial portion of the power-generating system in this embodiment also includes necessary sensor modules, wireless signal transceiver modules, and wind and / or solar energy storage modules. The sensor modules and wireless signal transceiver modules are connected to the ground module. The sensor modules are used to transmit information such as the position and attitude of the power parachute and the high-altitude environment (e.g., altitude, wind speed, wind direction). The energy storage modules provide power to at least the first driver 300 and the second driver 310. The sensor modules, wireless signal transceiver modules, and wind and / or solar energy storage modules are fixedly installed on the main cable 200 near the first driver 300 and / or the second driver 310. The specific installation can be achieved using any existing method, which will not be elaborated here.

[0075] In this embodiment, two actuators are fixedly mounted on the main cable. The actuators pull the drive cable, which in turn drives the walking mechanism to move along the main cable via a traction member fixed to the drive cable. This separates the necessary walking parts and the fixed parts of the aerial control system, effectively reducing the weight of the walking device and lowering drive energy consumption. Furthermore, since the energy-consuming devices are fixed relative to the main cable and do not move with the walking mechanism, it is easier to achieve recharging for extended operation. For example, small wind turbines or solar panels fixed to the main cable near the traction mechanism can be used to recharge the actuators and other electrical equipment, meeting the requirements for long-endurance operation.

[0076] Furthermore, replacing the climbing or friction-based traveling mechanism with a free-sliding traveling mechanism significantly reduces wear on the main cable, extends its service life, and enhances safety and reliability. Moreover, the method of using a drive rope to control stops and propel the traveling mechanism simplifies the system structure, making it easier to control and maintain.

[0077] Example 3

[0078] This embodiment provides a high-altitude wind energy utilization system. The difference between this embodiment and Embodiment 2 is the removal of the third stop 420; the rest of the structure is the same as in Embodiment 2. Different operating states of the high-altitude wind energy utilization system in this embodiment can be found in the appendix. Figures 5 to 9 .

[0079] In the open state, the locking head and locking sleeve 800 below the second traveling mechanism 510 are connected. The working umbrella 600, acting as the windward side, captures the immense wind force and transmits it to the second traveling mechanism 510 via the umbrella lines 610, and then to the main cable 200 via the locking head and locking sleeve 800 connector. The main cable 200, under this force, drives ground equipment to perform work or generate electricity. For specific details, please refer to [reference needed]. Figure 6 As shown.

[0080] When the air-guided balancing module 100 reaches the preset altitude limit, the system will switch to the parachute-closing mode. In parachute-closing mode, the ferrule 800 receives the parachute-closing command and immediately disconnects the mechanical connection with the ferrule of the second travel mechanism 510. The second travel mechanism 510 will rapidly ascend under the tension of the parachute lines, reaching the position of the second stop 410. At the same time, the working parachute 600, no longer restrained by the parachute lines 610, will rapidly fold under the influence of the wind, thus losing its wind-catching ability. (Reference to the state at the moment of parachute closure completion) Figure 7 As shown.

[0081] Next, the system will switch to reset mode. In reset mode, the first actuator 300 and the second actuator 310 cooperate to pull down the drive rope 700 according to the reset command. The first actuator 300 is in release mode, and the second actuator 310 is in retraction mode. At this time, the first stop 400 will slide down the main cable 200 following the drive rope 700, and push the first traveling mechanism 500 to drive the umbrella top to slide down the main cable 200 synchronously. The reset process is now complete.

[0082] Figure 8 The diagram shows the reset process. Throughout the reset, the canopy of the power parachute 600 remains folded, allowing the second actuator 310 to reset the second traveling mechanism 510 with minimal power consumption. In reset mode, the ground winch mechanism consumes only a small amount of energy while the parachute is closed, simultaneously pulling the entire aerial system back to the preset lower altitude limit.

[0083] Next, the system will switch back to the parachute opening mode. In this mode, the first actuator 300 and the second actuator 310 work together to pull the drive rope 700 upwards according to the opening command, with the first actuator 300 in retracting mode and the second actuator 310 in releasing mode. At this time, the second stop 410 will slide upwards on the main cable 200 following the drive rope 700, and after sliding a certain distance, it will push the first traveling mechanism 500 to move the parachute top upwards synchronously on the main cable 200. As the parachute top rises, the working parachute 600 will gradually return from its folded state to its normal state, creating a certain windward space inside. Then, driven by the wind, the working parachute will quickly open, assisting in pushing the parachute top to the designated opening position. The opening process is now complete. Figure 9 The diagram shows the opening process. Next, the working umbrella 600 will capture the wind force in the air again and transmit it to the main cable 200 through the umbrella ropes 610, the second walking mechanism 510, and the ferrule 800. The main cable 200 will then pull the ground equipment to perform work or generate electricity.

[0084] In the preferred embodiment, to increase output power, the windward area of ​​the canopy can be increased as much as possible while ensuring the material strength of the canopy fabric and ropes and the driving capability of the actuator. At the same wind speed, the system output power is directly proportional to the effective windward area of ​​the canopy.

[0085] In a more optimized design, to increase system output power and allow for flexible adjustment, multiple sets of power umbrellas and their corresponding drive systems can be installed on the main cable 200, forming a parachute ladder assembly. Each power umbrella in the ladder assembly can be flexibly opened and closed according to wind conditions and ground-based power / power generation needs. An example of the parachute ladder assembly built using this design is available for reference. Figure 5As shown, two or more drive and power umbrella modules are installed at appropriate intervals on the main cable 200.

[0086] Compared to Embodiment 2, this embodiment achieves the same operational effect. However, this embodiment reduces the third stop 420, resulting in a simpler structure. Furthermore, due to the appropriate upward shift of the second stop 410's mounting position on the main cable 200, the upward deceleration distance of the second traveling mechanism 510 is longer during umbrella closing. Under the same closing wind speed, the potential impact of the second traveling mechanism 510 on the second stop 410 is smaller, thus making it easier to maintain system structural safety when using a larger working umbrella. However, in this embodiment, the first driver 300 and the second driver 310 also drag the driving rope 700 a longer distance, which may slightly increase drive power consumption. Therefore, Embodiment 2 or this embodiment can be flexibly adopted according to the actual application scenario requirements.

[0087] Example 4

[0088] This embodiment provides a high-altitude wind energy utilization system. The difference between this system and those in embodiment 2 or 3 is that the drive rope 700 between the first stop 400 and the second stop 410 is replaced with a sliding tube 900 (e.g., Figure 10 As shown), or rope cage 910 (as shown). Figure 11 (As shown), the remaining structures can be referred to in Embodiment 2 or Embodiment 3. The different operating states of the high-altitude wind energy system in this embodiment can also be referred to in Appendix 2. Figures 1 to 5 .

[0089] In one exemplary scheme, such as Figure 10 As shown, compared to Embodiment 2, the drive rope 700 is divided into two sections. The two ends of the first section are connected to the take-up and release mechanism of the first driver 300 and the first stop 400, respectively. The two ends of the second section are connected to the take-up and release mechanism of the second driver 310 and the second stop 410, respectively. The lower end of the first stop 400 and the upper end of the second stop 410 are respectively installed on the upper and lower ends of the slide tube 900. The first stop 400, the second stop 410, and the slide tube 900 are all fitted onto the main cable 200 and can slide freely up and down along the main cable 200 under the traction of the drive rope 700. The third stop 420 (if present, as in Embodiment 3) is directly fitted onto the appropriate position on the outside of the slide tube 900. The non-rotating part inside the first traveling mechanism 500 is directly fitted onto the outside of the slide tube 900 and can slide freely up and down along the slide tube 900.

[0090] Compared to Embodiments 2 and 3, replacing a section of drive rope 700 between the first stop 400 and the second stop 410 with a slide tube 900 has the following advantages: First, it helps maintain a stable fit between the stop and the first traveling mechanism 500 and / or the second traveling mechanism 510 in recovery mode and re-opening mode, significantly eliminating the tilting effect caused by unilateral force on the stop; Second, since the slide tube 900 itself will not entangle with the main cable 200, replacing the drive rope between the first stop 400 and the second stop 410 with the slide tube 900 can significantly reduce the distribution length of the drive rope 700 on the main cable 200, further eliminating the risk of entanglement of the drive rope 700 on the main cable 200; Third, since the elastic deformation of the slide tube is generally smaller than that of the drive rope 700, using the slide tube 900 helps reduce the actual traction control length and control error of the first actuator 300 and the second actuator 310. However, since the slide tube 900 may be heavier than the drive rope 700 that it replaces, it will slightly increase the drive energy consumption of the first drive 300 and the second drive 310.

[0091] In another exemplary structure, such as Figure 11 As shown, the drive rope 700 between the first stop 400 and the second stop 410 can also be replaced with a rope cage 910 uniformly surrounding the main cable 200. The rope cage 910 can be composed of four or more single ropes evenly arranged circumferentially. The upper end of each single rope is uniformly connected to the lower end of the first stop 400, then passes down through the non-rotating part inside the first traveling mechanism 500, and then passes through the third stop 420 (if present, embodiment 3) fixedly installed on the rope cage. The ends of all the single ropes in the rope cage are uniformly connected to the upper end of the second stop 410. Compared with the sliding tube scheme, the rope cage scheme not only has all the advantages of the sliding tube scheme, but also, because the rope cage 910 is more flexible than the sliding tube 900, it is more conducive to operation during the ascent phase. Moreover, because the rope cage is lighter than the sliding tube, it helps to reduce the driving energy consumption of the first driver 300 and the second driver 310. The actual driving energy consumption may be basically equivalent to that of embodiment 2 or embodiment 3.

[0092] In addition, in order to take into account the advantages of the slide tube 900 and the rope cage 910, the drive structure between the first stop 400 and the second stop 410 can also be designed as a combination of the slide tube 900 and the rope cage 910. For example, the slide tube 900 can be used between the first stop 400 and the third stop 420, and the rope cage 910 can be used between the third stop 420 and the second stop 410, etc., which will not be elaborated here.
