Description

Technical Field

[0001] The present invention relates to the field of high-altitude wind energy, and more particularly to a method and device for opening and closing a dual-drive high-altitude wind energy parachute. Background Art

[0002] High-altitude wind energy is a renewable energy technology that harnesses wind power from 100 to several thousand meters above the ground. Compared to traditional ground-based wind power, high-altitude wind energy offers significant advantages: faster wind speeds, up to 5-10 times those at ground level, more stable winds, and higher energy density. High-altitude wind energy is captured by aircraft, floating platforms, or rotorcraft, and converted into electricity through mechanical transmission or onboard generators. This energy is then transmitted to the ground power grid via cables or wirelessly.

[0003] Chinese invention patent application number 201611246832.7 discloses a dual-drive umbrella-type wind energy conversion device and its opening and closing method, including: a cable; a block fixed to the cable; an umbrella body with its top center sleeved on the cable; two actuators sleeved on the cable and capable of moving back and forth on the cable, including: a first actuator connected to the top center of the umbrella body; a second actuator located between the block and the first actuator; the second actuator is connected to the umbrella body through an umbrella rope, and the umbrella rope is connected to the edge of the umbrella body; the second actuator and / or the block are provided with a locking mechanism that can lock the second actuator and the block. The device structure of this scheme is too simple and has many problems: first, the position of the second drive is uncertain after closing the parachute. If the first drive and the second drive descend at the same time, when they descend to the stop position of the second drive, the position of the first drive is uncertain. At the same time, the distance the first drive climbs up also becomes an uncertain value. Due to the uncertainty of the descending stop position of the first drive, the action of the first drive is quite blind; second, after closing the parachute, the parachute cloth is directly placed on the main cable, and when the parachute is opened, the first drive climbs up and it is very easy to roll up the thin parachute cloth, causing damage to the parachute body; third, when the horizontal angle of the parachute body is large, the first drive slides down to the position of the second drive, which is also likely to cause the parachute rope and parachute cloth to be tangled together, making it impossible to start opening the parachute again; fourth, when the first drive is climbing up, if If the parachute suddenly opens, the parachute will drive the first drive to climb up quickly, pushing the drive motor in reverse and causing damage to the motor structure. Fifth, the second drive is ejected at the moment the parachute is closed. If a generator is installed to convert it into electrical energy, the instantaneous power is extremely large and uncertain, which can easily cause damage to the circuit or generator. Sixth, the energy sources of the drive are solar energy, wind energy, and energy generated by the parachute above it. However, due to the limited size of the drive, solar panels cannot be arranged on a large area of ​​the drive. If a wind energy device is installed on the drive, it will easily increase the load on the drive during back and forth movement, and the wind energy device will easily interfere with the parachute and parachute ropes, and even break the parachute ropes and parachute cloth. Directly using the energy generated by the parachute is unstable due to large fluctuations. Therefore, the energy source of the drive also needs to be improved during use.

[0004] During application, the opening and closing method of the dual-drive umbrella-type wind energy conversion device has the following problems: the dual drive cannot determine the moving position, resulting in blind crawling and wasting energy; the lower drive is prone to collision with the upper drive when moving upward, causing damage to the drive and the entire umbrella to be unable to continue operating; the upper drive is prone to rolling the parachute into the drive when moving upward, causing damage to the parachute; the upper drive is easily affected by the parachute and pushed back, and the lower drive is easily affected by unlocking and ejected, causing damage to the motor; the energy source of the dual drive is unstable, resulting in low energy consumption efficiency. Summary of the Invention

[0005] The present invention aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provides a dual-drive high-altitude wind energy parachute opening and closing method and device, which is used to solve the problems that the dual drives cannot determine the moving position, resulting in blind crawling and wasting energy; the lower drive is prone to collide with the upper drive when moving upward, resulting in damage to the drive and the entire parachute cannot continue to operate; the upper drive rolls the parachute into the drive when moving upward, resulting in damage to the parachute; after the parachute is folded, the light weight of the umbrella cloth is easily rolled into the upper drive, resulting in the inability to perform the parachute opening action, the parachute fails to fold, and thus affects the work efficiency of the parachute; the upper drive is easily affected by the parachute and pushed back, and the lower drive is easily ejected due to the unlocking, resulting in damage to the motor; the energy source of the dual drives is unstable, resulting in low energy replenishment efficiency.

[0006] The technical solution adopted by the present invention is a dual-drive high-altitude wind energy parachute opening and closing method, which includes: a cable; a parachute body including parachute lines and parachute cloth; an upper driver and a lower driver sleeved on the cable and capable of moving back and forth on the cable, the parachute cloth is connected to the upper driver, and the parachute lines are connected to the lower driver; a locking assembly is arranged on the cable below the lower driver, for locking or unlocking with the lower driver; an origin position is set on the cable between the upper driver and the lower driver, and a set position is set on the cable above the origin position; the cyclic action of the parachute body from the open state to the closed state and then to the open state includes:

[0007] S1. The parachute is in an open state, the lower drive and the locking assembly are locked, the upper drive is in a set position, the lower drive and the locking assembly are unlocked, the damping in the lower drive is activated, and the lower drive moves passively upward along the cable;

[0008] S2. When the stroke difference between the lower and upper actuators reaches a critical value, both the lower and upper actuators actively move downward along the cable. When the stroke difference between the lower and upper actuators does not reach the critical value, the upper actuator actively moves downward along the cable until the stroke difference reaches the critical value.

[0009] S3. The lower drive line to the locking assembly, and the locking assembly is locked, the upper drive line to the origin position, the umbrella is closed;

[0010] S4. The upper actuator actively moves upward along the cable from the origin until it reaches the set position and the parachute is fully opened.

[0011] Through the above-mentioned parachute opening and closing method, the movement of the dual actuators on the cables is no longer blind. The original position and the set position are coordinated to achieve precise displacement control of the upper actuator and the lower actuator, shortening the crawling distance of the upper actuator during the parachute opening and closing process, thereby saving the crawling energy consumption of the upper actuator. At the same time, a controlled spacing is maintained between the upper actuator and the lower actuator, which not only avoids entanglement between the parachute and the dual actuators, but also helps to shorten the parachute opening and closing time, improve the work efficiency of the parachute, and avoid the possibility of collision between the dual actuators.

[0012] Furthermore, step S2 includes the following steps:

[0013] S21. Feedback of the moving distance d1 by the encoder in the upper drive;

[0014] S22 feedback through the encoder in the lower drive moving distance d2;

[0015] S23. Calculate the travel difference D = d2-d1;

[0016] S24. The radius of the parachute is R. Determine whether the stroke difference reaches the critical value:

[0017] When D ≥ R, the stroke difference reaches the critical value;

[0018] When D<R and the encoder speed in the lower driver is 0, the upper driver moves downward so that the stroke difference reaches a critical value, D=R.

[0019] The encoder precisely controls the distance difference between the upper and lower actuators when the parachute is ready to close, ensuring that there is always a gap between the two during movement, preventing the parachute from being drawn into the actuators.

[0020] Furthermore, in step S2, the upper driver first actively moves upward along the cable. If the stroke difference of the upper driver or the lower driver does not reach the critical value due to low wind speed, the upper driver is then actively moved downward along the cable.

[0021] By actively controlling the movement direction of the upper drive and its movement distance, the movement position of the lower drive is reduced, the energy consumption of the dual drives on the cable is reduced, and the working time of the dual drives when converting wind energy at high altitude is extended.

[0022] Furthermore, the origin position is the sensing position, the set position is the calculated position, and the distance traveled by the upper driver to reach the set position in step S4 is calculated based on the number of turns set by the encoder.

[0023] By adopting a fixed sensing method for the origin position, an absolute position reference is provided for the encoders in the upper and lower drives, ensuring that the encoders can quickly and accurately calibrate the initial position when position drift may occur during long-term operation or when starting and resetting, thereby avoiding cumulative errors; by calculating the set position, the precise position of the upper and lower drives on the cable can be controlled.

[0024] Furthermore, after the upper driver reaches the set position in step S4, the following steps are further included: starting the damping in the upper driver to lock the upper driver at the set position, wherein the damping is set with a critical threshold.

[0025] The upper drive is locked in the set position through damping, so that the parachute is in an expanded state, which is convenient for improving the work efficiency of the parachute; the force applied to the upper drive is distinguished by a set critical threshold, ensuring that when the force applied to the upper drive exceeds the critical threshold, it can be restored to the set position in time. At the same time, the damping setting replaces the traditional hook lock, reducing the wear and damage of the hook lock to the cable.

[0026] Furthermore, when the lower drive and the locking component are in a locked state, the lower drive is in an energizing state; when the lower drive and the locking component are in an unlocked state, the energizing state of the lower drive stops; except for the upper drive moving to the origin and stopping energizing in step S2, the upper drive is always in an energizing state at other times.

[0027] By replenishing the energy of the upper and lower drives, the parachute can work continuously, extending the service life of the dual drives, improving the working efficiency of the parachute, and avoiding the problem of insufficient drive energy requiring the parachute to be retracted and returned to the ground for charging.

[0028] A dual-drive high-altitude wind energy parachute opening and closing device, according to a dual-drive high-altitude wind energy parachute opening and closing method, comprising:

[0029] Cables;

[0030] The parachute body at the top center is connected to the cable, including the parachute cloth and parachute rope;

[0031] Two actuators are sleeved on the cable and can move back and forth on the cable, including: an upper actuator connected to the top center of the parachute cloth; a lower actuator connected to the center of the parachute rope;

[0032] The locking component controls the opening and closing state of the parachute by connecting or disconnecting with the lower drive;

[0033] The displacement control component comprises an induction ring and an encoder. The induction ring is arranged at an origin position, and the encoder controls the displacement of the driver on the cable.

[0034] The transmission of high-altitude wind energy is achieved through cables; a kite-like folding and releasing cycle is achieved through the parachute and the parachute rope, thereby capturing high-altitude wind energy; the rapid opening and closing of the parachute is achieved through two drives, thereby achieving efficient conversion of the parachute's work capacity; the opening and closing states of the parachute are switched by unlocking and locking the locking component; the precise movement distance of the two drives is controlled by the displacement control component, thereby reducing excessive movement of the drives and saving drive energy consumption. The absolute position information is reflected by the induction ring, and high-resolution position feedback is provided by the encoder, so that the upper and lower drives use the absolute position information of the induction ring as the reference, and achieve the set circle value of the encoder as the set position, thereby achieving precise control of the moving distance, thereby shortening the blind movement distance and saving drive energy consumption.

[0035] Furthermore, it also includes an isolation assembly fixed on the cable, the isolation assembly includes an isolation piece and a universal joint, the isolation piece is used to isolate the umbrella body from the upper drive and the cable when the umbrella body is folded, and the universal joint is connected between the isolation piece and the upper drive, and is used to compensate for the dynamic angle of the umbrella body when the umbrella body is switched to be opened or closed, and when the wind speed and wind direction change.

[0036] The parachute body is isolated from the upper drive by the isolator, and the dynamic angle compensation is performed by the universal joint along the floating parachute rope to prevent the parachute rope from being entangled in the drive; the anti-roll effect is achieved by the isolation component, thereby avoiding affecting the opening and closing efficiency and work efficiency of the parachute body.

[0037] Furthermore, it also includes at least one energy replenishment component, which is fixed on the cable and is used to replenish energy of the upper drive and / or the lower drive; the energy replenishment component includes a first energy replenishment component for replenishing energy for the upper drive, a second energy replenishment component for replenishing energy for the lower drive, a magnetic component and a telescopic cable, the first energy replenishment component is connected to the upper drive through the telescopic cable and the magnetic component, and the second energy replenishment component is connected to the lower drive through a locking component.

[0038] By arranging the energy charging component on the cable and connecting it to the driver, it is avoided that the energy charging component is directly installed on the driver, which increases the load of the driver and interferes with the parachute rope and the parachute body, thereby achieving stable replenishment of the driver's energy source and improving the driver's energy consumption efficiency; by using two energy charging components to respectively supply energy to the two drivers, stable energy replenishment of the two drivers without interfering with or affecting each other is achieved; by using a magnetic suction component and a telescopic cable, the transmission efficiency of the first energy charging component to the upper driver is enhanced, thereby avoiding the problem that the upper driver cannot align with the interface of the first energy charging component during movement, thereby further improving the energy collection and conversion efficiency.

[0039] Furthermore, the lower drive is provided with a battery, a rotating assembly, a crawling assembly, a switching clutch assembly, a damping assembly and a communication assembly:

[0040] The rotating assembly is used to cooperate with the rotation of the parachute rope;

[0041] The crawling assembly provides power for the crawling of the lower drive;

[0042] The switching clutch assembly is used to switch damping and power;

[0043] The damping component is used to consume the instantaneous energy when the parachute is folded;

[0044] The communication component is used for communication with the upper drive, the locking component and the energy replenishing component.

[0045] Rotation is achieved through the cooperation of the rotating component on the lower drive with the parachute rope; the crawling component provides power for the crawling of the lower drive itself; the switching of the motor and the damping is achieved by switching the clutch component, and the energy generated at the moment of closing the parachute is consumed by the damping component to prevent the lower drive from colliding with the upper drive; the communication component is used to achieve communication between the lower drive and the ground, the upper drive, the locking component, and the energy replenishment component.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1) The displacement control assembly enables precise control of the movement distance of the upper and lower actuators, avoiding blind crawling and wasting energy. It also shortens the crawling distance of the upper actuator and saves the energy consumption of the actuator. At the same time, it also avoids collision between the upper and lower actuators during movement and prevents the parachute from being drawn into the actuators.

[0048] 2) The isolation component prevents the parachute from being drawn into the actuator, thereby improving the parachute opening and closing efficiency and the energy conversion efficiency of the parachute during work;

[0049] 3) Prevent the motor in the driver from burning out by setting the damping component in the driver;

[0050] 4) Capture and transmit wind energy when the parachute is folded through telescopic cables;

[0051] 5) The energy supply of the two drivers is stably supplemented by the energy replenishment component, and the energy supply can be increased or decreased according to the actual energy consumption of the parachute, so that the parachute is in a working state for a long time, avoiding the problem of the drivers needing to be pulled back to the ground for charging due to insufficient power supply, thereby improving the efficiency of the drivers.

DETAILED DESCRIPTION

[0062] The accompanying drawings are for illustrative purposes only and are not to be construed as limiting the present invention. To better illustrate the following embodiments, some components in the accompanying drawings may be omitted, enlarged, or reduced in size, and do not represent actual product dimensions. Those skilled in the art will appreciate that some well-known structures and their descriptions may be omitted from the accompanying drawings.

[0063] Example 1

[0064] like Figure 1-9As shown, this embodiment provides a dual-drive high-altitude wind energy parachute opening and closing method, which includes: a cable 1; a parachute including parachute lines 81 and parachute cloth 82; an upper actuator 7 and a lower actuator 5 sleeved on the cable 1 and capable of moving back and forth on the cable 1, the parachute cloth 82 being connected to the upper actuator 7, and the parachute lines 81 being connected to the lower actuator 5; a locking assembly disposed on the cable 1 below the lower actuator 5 for locking or unlocking the lower actuator 5; an origin position is disposed on the cable 1 between the upper actuator 7 and the lower actuator 5, and a set position is disposed on the cable 1 above the origin position; the cyclic movement of the parachute from the open state to the closed state and then to the open state includes:

[0065] S1. The parachute is in an open state, the lower drive 5 is locked with the locking assembly, the upper drive 7 is in a set position, the lower drive 5 and the locking assembly are unlocked, the damping in the lower drive 5 is activated, and the lower drive 5 is passively moved upward along the cable 1;

[0066] S2. When the stroke difference between the lower drive 5 and the upper drive 7 reaches a critical value, the lower drive 5 and the upper drive 7 are actively moved downward along the cable 1. When the stroke difference between the lower drive 5 and the upper drive 7 does not reach the critical value, the upper drive 7 actively moves downward along the cable 1 so that the stroke difference reaches the critical value;

[0067] S3. The lower drive 5 goes to the locking assembly, and the locking assembly is locked, the upper drive 7 goes to the origin position, the umbrella is closed;

[0068] S4. The upper driver 7 actively moves upward from the origin position along the cable 1 until it reaches the set position and the parachute is fully opened.

[0069] The opening and closing method of this embodiment is specifically as follows: in the open state of the umbrella, the lower actuator 5 is locked with the locking assembly, one end of the parachute cord 81 is centrally connected to the locking assembly and maintained taut, and the other end of the parachute cord 81 provides uniform tension to the edges of the umbrella fabric 82, keeping the umbrella fabric 82 open at high altitude under the action of wind. One end of the upper actuator 7 is located at the top center of the umbrella fabric 82, the induction ring 5 is located between the upper actuator 7 and the lower actuator 5, and the upper actuator 7 is maintained at a predetermined distance from the origin. When the umbrella changes from the open state to the closed state, the lower actuator 5 is unlocked from the locking assembly, and the lower actuator 5 is ejected upward along the cable 1 under the action of wind. After the upper actuator 7 actively moves upward along the cable 1 by a distance at least one times the radius of the umbrella fabric 82, the lower actuator 5 begins to move downward along the cable 1, and the upper actuator 7 simultaneously begins to move downward along the cable 1 until the lower actuator 5 and the locking assembly are locked again, and the upper actuator 7 is at the origin. When the umbrella changes from a closed state to an open state: the lower driver 5 and the locking assembly remain locked, and the upper driver 7 actively moves upward along the cable 1 until it reaches the set position of the number of turns set by the encoder. At this time, driven by the upper driver 7, the parachute rope 81 is tightened step by step, so that the umbrella cloth 82 is fully opened.

[0070] Step S2 includes the following steps:

[0071] S21. Feedback of the moving distance d1 by the encoder on the upper drive 7;

[0072] S22 feedback through the encoder of the lower drive 5 moving distance d2;

[0073] S23. Calculate the travel difference D = d2-d1;

[0074] S24. The radius of the parachute is R. Determine whether the stroke difference reaches the critical value:

[0075] When D ≥ R, the stroke difference reaches the critical value;

[0076] When D<R and the encoder speed in the lower driver is 0, the upper driver moves downward so that the stroke difference reaches a critical value, D=R.

[0077] In step S2 , the upper driver 7 first actively moves upward along the cable 1 . If the stroke difference of the upper driver or the lower driver does not reach the critical value due to low wind speed, the upper driver 7 is then actively moved downward along the cable 1 .

[0078] In this embodiment, after the lower driver 5 is unlocked from the locking assembly, the lower driver 5 passively moves upward along the cable 1, and the upper driver 7 actively moves upward along the cable 1, the umbrella rope 81 and the umbrella cloth 82 are in a relaxed state. In order to prevent the umbrella rope 81 and the umbrella cloth 82 from being entangled in the two drivers, it is necessary to use the encoders in the two drivers to respectively feedback the accurate moving distance, and ensure that the stroke difference between the two is always greater than or equal to 1 times the radius of the umbrella cloth 82.

[0079] The origin position is the sensing position, the set position is the calculated position, and the distance traveled to reach the set position in step S4 is calculated by the number of turns set by the encoder.

[0080] In this embodiment, when the upper driver 7 returns to the origin position, the sensing information is transmitted to the encoder therein, so that the encoder has a zero point reference. When the upper driver 7 is in motion, the encoder in the upper driver 7 emits pulses to calculate the displacement from the zero point. When the number of circles in the encoder reaches the set N circles, it indicates that the upper driver 7 has moved to the set position.

[0081] After the upper driver 7 reaches the set position in step S4, the following steps are also included: starting the damping in the upper driver 7 to lock the upper driver 7 at the set position, and the damping is set with a critical threshold.

[0082] In this embodiment, the damping is activated after reaching a critical threshold value, so that the upper driver 7 is maintained in the set position, thereby ensuring the stability of the parachute when it is in the open state, thereby improving the work efficiency of the parachute. At the same time, the damping set in the upper driver 7 makes it possible to fix the upper driver 7 on the cable 1 without relying on a traditional hook lock, thereby avoiding the upper driver 7 being locked on the cable 1 and causing damage to the cable 1.

[0083] When the lower driver 5 and the locking component are in a locked state, the lower driver 5 is in an energizing state; when the lower driver 5 and the locking component are in an unlocked state, the energizing state of the lower driver 5 stops; except for the upper drive moving to the origin and stopping energizing in step S2, the upper driver 7 is always in an energizing state at other times.

[0084] In this embodiment, the lower actuator 5 only recharges energy when locked with the locking assembly. The upper actuator 7 cannot recharge energy when it reaches the origin position, but can recharge energy while in motion on the cable 1 or when it reaches the set position. When the upper actuator 7 actively moves downward along the cable 1 in step S2, the upper actuator 7 is in the recharge state. When it continues to move to the origin position, the recharge state of the upper actuator 7 ceases. When the upper actuator 7 actively moves upward along the cable 1 from the set position in step S1, and when it actively moves upward along the cable 1 to the set position in step S4, the upper actuator 7 remains in the recharge state. Both actuators can maintain continuous operation for long periods of time in the recharged state, improving the operating efficiency of the parachute.

[0085] Example 2

[0086] This embodiment provides a dual-drive high-altitude wind energy parachute opening and closing device, according to a dual-drive high-altitude wind energy parachute opening and closing method, which includes:

[0087] Cable 1;

[0088] The parachute body is sleeved on the cable 1 at the top center, including the parachute cloth 82 and the parachute rope 81;

[0089] Two actuators are sleeved on the cable 1 and can move back and forth on the cable 1, including: an upper actuator 7 connected to the top center of the umbrella cloth 82; a lower actuator 5 connected to the center of the umbrella rope 81;

[0090] The locking assembly controls the opening and closing state of the parachute by connecting or disconnecting with the lower drive 5;

[0091] The displacement control component includes an induction ring and an encoder. The induction ring is set at the origin position, and the encoder controls the displacement of the driver on the cable 1.

[0092] In this embodiment, a cable 1 passes through the center of the umbrella fabric 82 and is connected in series with other components to capture and transmit high-altitude wind energy. Two actuators are located along the cable 1, one on the upper and one on the lower sides of the umbrella. The upper actuator 7 is located on the upper side, and the lower actuator 5 is located on the lower side. When the umbrella changes from an open state to a closed state, the lower actuator 5 must first be unlocked and then locked with the locking assembly. Under the guidance of the displacement control assembly, the upper actuator 7 descends along the cable 1 to the origin position, while the lower actuator 5 descends along the cable 1 to the locking position of the locking assembly under the guidance of the displacement control assembly. When the umbrella changes from a closed state to an open state, the lower actuator 5 remains locked with the locking assembly, and the upper actuator 7 ascends along the cable 1 to a set position under the guidance of the displacement control assembly. The locking assembly includes a lock buckle 3 and a lock head 4, which are interchangeable. It also includes components or components such as a locking assembly, a motor, a control circuit, and a position detection switch.

[0093] In this embodiment, the displacement control assembly includes an induction ring 5 and an encoder. The induction ring 5 is positioned between the upper and lower actuators 7, and is used to set the origin of the upper actuator 7. The encoder is coaxial with the induction ring 5 and includes two encoders, one in each actuator, to provide position feedback for the upper and lower actuators 7 and 5. The induction ring 5 establishes a zero position for the upper and lower actuators 7 and 5. The distance calculated based on the set number of revolutions on the encoder is the distance traveled by the upper actuator 7 to reach the set position. The induction ring 5 and the encoder work together to precisely control the movement of the upper actuator 7 to the set position or origin. Furthermore, the displacement of the upper and lower actuators 7 and 5 can be used to reflect the opening and closing status of the parachute, and this status can be fed back to a ground monitoring system. The lower actuator 5 is equipped with a position detection proximity switch. The induction ring 5 is made of a suitable material, preferably a magnetically conductive material, depending on the type of proximity switch.

[0094] In this embodiment, the cable 1 includes a load-bearing core 101 and a braided protective sheath 102, and the induction ring 5 is disposed between the load-bearing core 101 and the braided protective sheath 102, or the induction ring 5 is disposed outside the braided protective sheath 102. The induction ring 5 is located between the load-bearing core 101 and the braided protective sheath 102, and when the length of the parachute cord 81 is greater than 2.5 times the radius of the parachute cloth 82, the induction ring 5 can be fixed outside the braided protective sheath 102.

[0095] It also includes an isolation assembly fixed to the cable 1, the isolation assembly includes an isolation piece 10 and a universal joint 9, the isolation piece 10 is used to isolate the umbrella body from the upper drive 7 and the cable 1 when the umbrella body is closed, and the universal joint 9 is connected between the isolation piece 10 and the upper drive 7, and is used to compensate for the dynamic angle of the umbrella body when the umbrella body is opened or closed and when the wind speed and direction change.

[0096] In this embodiment, the spacer 10 is used to support the closed umbrella, preventing the fabric 82 from becoming entangled in the upper drive 7. The spacer 10 and upper drive 7 are connected via a universal joint 9, to which are connected several lines 81. When the upper drive 7 ascends or descends, the fabric 82 rotates due to wind force, causing the lines 81 to deflect. The universal joint 9 compensates for the dynamic angle of deflection of the lines 81, preventing the lines 81 from becoming entangled in the upper drive 7. The spacer 10, wrapped around the cable 1, is elongated and cylindrical, with a length greater than or equal to the radius of the fabric 82. This ensures that the fabric 82 is fully supported when it flips and lands on the spacer 10.

[0097] It also includes at least one energy replenishment component, which includes a first energy replenishment component 22 for replenishing energy for the upper drive 7, a second energy replenishment component 21 for replenishing energy for the lower drive 5, a magnetic component 11 and a telescopic cable 12. The first energy replenishment component 22 is connected to the upper drive through the telescopic cable and the magnetic component, and the second energy replenishment component 21 is connected to the lower drive through a locking component.

[0098] In this embodiment, a single first energy-replenishing assembly 22, or multiple components connected in series, replenishes energy for the upper driver 7. A single second energy-replenishing assembly 21, or multiple components connected in series, replenishes energy for the lower driver 5. The energy replenishment states of the first energy-replenishing assembly 22 and the second energy-replenishing assembly 21 do not interfere with each other. The energy-replenishing assembly comprises a combination of one or more photovoltaic generators, wind turbines, batteries, and control panels, enabling a variety of energy replenishment solutions.

[0099] In this embodiment, the photovoltaic generator includes a cable 1, a photovoltaic generator fixing ring 201, and photovoltaic panels 202. The photovoltaic panels 202 surround a hexagonal prism. Except for one downward-facing face, all seven faces are equipped with photovoltaic panels 202. The photovoltaic generator fixing ring 201 secures the hexagonal prism to the cable 1. One or more hexagonal prisms can be fixed as needed to supply power to the upper driver 7 or the lower driver 5. If multiple hexagonal prisms are used, only the topmost hexagonal prism has an upper end face.

[0100] In this embodiment, the wind turbine generator includes a combination of multiple wind turbine generators or a central cable-threaded wind turbine generator.

[0101] In this embodiment, the plurality of wind turbines comprises a cable 1, a bracket 203, and six individual wind turbines 204. The six individual wind turbines 204 are evenly distributed on the bracket 203, which is fixed to the cable 1. To reduce the torque transmitted to the cable 1, each wind turbine 204 is equipped with six blades, three of which rotate clockwise and three rotate counterclockwise.

[0102] In this embodiment, the central cable-through wind turbine generator includes a cable 1, a generator 205, a blade angle adjustment device 206, blades 207, and a central cable-through wind turbine fixing ring 208. The central cable-through wind turbine fixing ring 208 secures the entire generator to the cable 1. Central cable-through wind turbines are typically installed in pairs, passing through and fixed to the cable 1 to reduce the torque transferred to the cable 1. Blades 207 adjust the power generation angle based on wind speed or the angle of the cable 1. Compared to a combination of multiple wind turbines, the blades 207 of a central cable-through wind turbine generator have a larger windward area and greater power.

[0103] In this embodiment, a telescopic cable 12 is disposed between the upper driver 7 and the first energy-charging assembly 22. One end of the telescopic cable 12 is connected to the magnetic assembly 11, and the other end is connected to the first energy-charging assembly 22. The magnetic assembly 11 allows the telescopic cable 12 to extend and contract. This allows the first energy-charging assembly 22 to align with the charging port of the upper driver 7 even when the upper driver 7 is spaced from the first energy-charging assembly 22 during movement, ensuring stable charging of the upper driver 7 during operation and avoiding impacting the operating efficiency of the upper driver 7. The telescopic cable 12 can also be disposed between the isolator 10 and the first energy-charging assembly 22, with one end of the isolator 10 connected to the upper driver 7 and the other end connected to the magnetic assembly 11.

[0106] The crawling assembly provides power for the crawling of the lower drive 5;

[0107] The switching clutch assembly is used to switch damping and power;

[0108] The damping component is used to consume the instantaneous energy when the parachute is folded;

[0109] The communication component is used for communication with the upper drive 7, the locking component, and the energy replenishment component.

[0110] In this embodiment, the lower actuator 5 includes a rotation assembly connected to the parachute lines 81, a position detection proximity switch, a creeping assembly, a switching clutch assembly, a damping assembly, and a communication assembly. The position detection proximity switch is used to detect the position of the lower actuator 5, the lock buckle 3, and the lock head 4. The rotation assembly coordinates the rotation of the parachute lines 81. The creeping assembly provides power for the creeping movement of the lower actuator 5. The switching clutch assembly is used to switch between damping and power. The damping assembly is used to dissipate instantaneous energy when the parachute is closed. The communication assembly is used to communicate with the upper actuator 7, the locking assembly, and the energy charging assembly.
