Description

Technical Field

[0001] This invention relates to the field of high-altitude wind energy, and more specifically, to a winch-type umbrella-shaped wind energy opening and closing method, conversion device, and power generation system. Background Technology

[0002] High-altitude wind energy is a widely distributed and abundant renewable and clean energy source. Studies indicate that wind energy at high altitudes is directly proportional to the cube of wind speed; generally, a doubling of wind speed results in an eightfold increase in wind energy. Therefore, high-altitude wind energy can be tens, even hundreds or thousands of times greater than ground-based wind energy. In ideal high-altitude locations, theoretical high-altitude wind power generation can reach 95% of the year, with annual power generation exceeding 8200 hours. Even a small-capacity 10-megawatt high-altitude wind power system generates over 5000 hours of electricity annually. Therefore, high-altitude wind power generation offers advantages such as high average energy density, wide geographical distribution, high stability, and low unit cost.

[0003] A common high-altitude wind power generation system includes an umbrella-shaped wind energy conversion device (or a high-altitude kite), a main cable, a winch, and a generator. The umbrella-shaped wind energy conversion device opens and remains stable in the air. Under the influence of high-altitude winds, it rises and pulls the main cable. The upward pull of the main cable drives the winch on the ground, which in turn drives the generator to produce electricity, thus converting wind energy into mechanical energy, and mechanical energy into electrical energy. After reaching its final height, the umbrella-shaped wind energy conversion device needs to close. The winch then winds up the main cable, pulling the umbrella-shaped wind energy conversion device back to its starting height, and then reopens in the air for the next power generation cycle, repeating this process. For details, please refer to Chinese Patent CN102220938B - Umbrella-shaped Wind Power Device and Wind Power System.

[0004] Umbrella-type wind energy conversion devices require repeated opening and closing, making a simple, efficient, and reliable opening and closing method particularly important. Chinese Patent CN106523273B – A dual-drive umbrella-type wind energy conversion device and its opening and closing method – describes a device comprising: a cable; a stop fixed to the cable; an umbrella body with its top center sleeved on the cable; a first actuator connected to the top center of the umbrella body; a second actuator located between the stop and the first actuator; the second actuator is connected to the umbrella body via an umbrella cable, and the umbrella cable is connected to the edge of the umbrella body; the second actuator and / or the stop are provided with a locking mechanism capable of locking the second actuator and the stop. This solution primarily uses two actuators moving back and forth on the cable to achieve the opening and closing of the umbrella-type wind energy conversion device. The opening and closing process requires only a few movements, and the use of wind power during the process greatly reduces the energy consumption of the actuators. A similar example is Chinese Patent CN106523274B – A single-drive umbrella-type wind energy conversion device and its opening and closing method. Since the actuator in the above scheme needs to move back and forth on the cable and remain fixed, the reliability requirements of the actuator structure and the strength and wear resistance requirements of the cable are relatively high. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of at least one of the above-mentioned prior art, and provides a winch-type umbrella-shaped wind energy opening and closing method, conversion device and power generation system, to solve the opening and closing problem of umbrella-shaped wind energy conversion device, and achieve the effect of simplicity, efficiency and reliability.

[0006] The technical solution adopted in this invention is a winch-type umbrella-shaped wind energy opening and closing method, wherein one end of a first cable is wound onto a first drum, and the other end is tied to the edge of the umbrella canopy; one end of a second cable is wound onto a second drum, and the other end is tied to the top of the umbrella canopy; the method includes the following stages:

[0007] During the ascent phase, the high-altitude wind energy drives the power parachute to rise. The first and second cables are released, the first cable pulls the first drum to rotate, and the second cable pulls the second drum to rotate. The power parachute stops rising after reaching a certain height.

[0008] During the closing phase, the working umbrella continues to rise to the first height, the first cable continues to release the rope, the second cable stops releasing the rope, the edge of the working umbrella continues to rise and folds upward, and the working umbrella closes.

[0009] During the descent phase, the motor drives the first drum and the second drum to rotate simultaneously, and the first cable and the second cable are wound up. The first drum winds up the first cable, and the second drum winds up the second cable. The first cable and the second cable pull the power parachute down. The power parachute stops after descending to a certain height.

[0010] During the opening phase, the power parachute continues to descend to the second altitude, the first cable continues to be wound up, the second cable stops being wound up, the edge of the power parachute continues to descend and folds downward, and the power parachute opens.

[0011] The first cable can only be released after it has been unlocked.

[0012] The winch-type umbrella-type wind power opening and closing method of this scheme is applicable to the above-mentioned high-altitude wind power generation system of ground power generation type. The first drum, the second drum, and the motor are all fixed to the main cable. The working umbrella is opened and closed by the traction control of the first and second cables. After the working umbrella completes its opening in the air and remains stable, it can pull the main cable upward, thereby driving the ground generator to generate electricity. The opening and closing method of this scheme specifically includes the following stages:

[0013] During the ascent phase, wind power drives the parachute upwards, releasing the first cable and pulling it up along both cables. The first cable rotates the first drum, and the second cable rotates the second drum. Once the parachute reaches a certain height, the first cable is locked, tightening the parachute and stopping its ascent. At this point, the parachute has completed its deployment and remains stable in the air, allowing it to signal the completion of deployment.

[0014] During the closing phase, upon receiving the closing signal, the first cable is unlocked and released, allowing the wind-driven parachute to continue rising to the first height. The second drum stops rotating, the second cable stops releasing rope and tightens the top of the parachute canopy; the wind-driven edge of the parachute canopy continues to rise and fold upwards, the first cable continues releasing rope, and the first drum continues rotating until the parachute is fully closed. After the parachute is closed, the first cable is locked and released rope is stopped.

[0015] During the descent phase, the motor starts and drives the first and second drums to rotate simultaneously. The first drum winds up the first cable, and the second drum winds up the second cable. The first and second cables simultaneously pull the closed parachute downwards. After the parachute reaches a certain height, the motor shuts off, the first and second cables stop winding, and the parachute stops descending. At this point, the parachute has closed in mid-air and can send a signal indicating that it has closed.

[0016] During the opening phase, upon receiving the opening signal, the motor restarts, and the first and second cables simultaneously pull the closed parachute down to the second height. The second drum stops rotating, the second cable stops winding, and wind power drives the top of the parachute canopy upwards; simultaneously, the motor continues to drive the first drum to rotate, the first cable continues winding, and pulls the edge of the parachute canopy downwards, folding it down, thus completing the opening of the parachute. After the parachute opens, the motor shuts off, the first drum stops rotating, and the first cable stops winding.

[0017] This solution utilizes a combination of a traditional drum and a motor to differentiate the timing of rope retraction and release between the first cable located at the edge of the umbrella canopy and the second cable located at the top of the umbrella canopy, enabling the working umbrella to open and close with the help of wind power. By locking the release of the first cable at appropriate times, the working umbrella can be kept in an open or closed state. This solves the problem of opening and closing umbrella-type wind energy conversion devices, achieving a simple, efficient, and reliable result.

[0018] Preferably, the system also includes a locking mechanism. In the locked state, the first cable can only be wound up; in the unlocked state, the first cable can be wound up and unwound. This solution ensures that the first cable can only be unwound after the locking state is lifted. As can be seen from the four stages described above, the first cable only needs to be locked to prevent unwinding, not to prevent winding up. Therefore, the locking mechanism can be designed as a one-way locking mechanism, meaning that in the locked state, winding up is allowed while winding up is locked, and in the unlocked state, both winding up and unwinding are allowed. Compared to a two-way locking mechanism, when the first cable is wound up, the locking mechanism does not require energy to unlock, thus reducing the power generation system's own losses and improving its power generation efficiency.

[0019] Furthermore, the locking mechanism is located between the power umbrella and the first drum, and the first cable is wound onto the first drum after being connected in series with the locking mechanism. In this design, wind power drives the power umbrella to rise, and the first cable transmits tension to pull the main cable upward to generate electricity. For large power umbrellas, in order to reliably lock the first cable and transmit greater tension, the locking mechanism needs to be separately installed between the power umbrella and the first drum. After the first cable is connected to the edge of the umbrella canopy, it first passes through the locking mechanism and then is wound onto the first drum.

[0020] Preferably, the edge of the umbrella canopy is attached to the first cable; one point is connected to the main cable via a roller, allowing the umbrella to rise and fall along the main cable. In this design, the edge of the umbrella canopy is fixedly connected to the first cable, while one point is movably connected to the main cable. This design restricts the movement of the umbrella along the main cable, maintaining a better aerial posture; it also allows the umbrella to rotate around the main cable under wind force when opening and closing, making opening and closing easier, more efficient, and more reliable. Using a roller for the movable connection reduces wear between the edge of the umbrella canopy and the main cable.

[0021] This solution also provides a winch-type umbrella-shaped wind energy conversion device, which is fixed to the main cable and uses the above-mentioned winch-type umbrella-shaped wind energy opening and closing method to open and close the umbrella; including a double-cylinder cable winch device.

[0022] The double-drum cable winch includes a winch body and a first drum, a second drum, a winch shaft, and a switching assembly mounted on the winch body. The first drum, the switching assembly, and the second drum are sequentially arranged side-by-side on the winch shaft. When the switching assembly is switched to a first state, the first drum rotates synchronously with the winch shaft. When the switching assembly is switched to a second state, the second drum rotates synchronously with the winch shaft. When the switching assembly is switched to an intermediate state, the first drum, the second drum, and the winch shaft rotate synchronously. The winch shaft is connected to the motor.

[0023] Preferably, the switching assembly includes a first gear, a second gear, a third gear, a gear ring, a shift fork, and a linear drive; the first gear is fixed to one side of the first drum, the second gear is fixed to one side of the second drum, the third gear is fixed to the middle of the winch shaft, and the gear ring is sleeved on the outside of the third gear; the linear drive pushes the shift fork to move the gear ring, so that the first gear, gear ring, and third gear mesh with each other, or the second gear, gear ring, and third gear mesh with each other, or the first gear, second gear, gear ring, and third gear mesh with each other.

[0024] Furthermore, the linear drive includes a switching motor and a linkage mechanism; the switching motor is fixed to the winch body; the linkage mechanism connects the switching motor and the shift fork, and the linkage mechanism is used to convert the rotational motion of the switching motor into the linear motion of the shift fork.

[0025] This solution also provides another type of winch-type umbrella-shaped wind energy conversion device, which is fixed to the main cable and uses the above-mentioned winch-type umbrella-shaped wind energy opening and closing method to open and close the umbrella; it includes a rope ladder and a rope ladder locking device; the rope ladder locking device is the locking mechanism; the first cable is wound onto the first drum after being connected to the rope ladder locking device in series with the rope ladder.

[0026] The rope ladder locking device includes a locking body and a rope ladder channel, a locking pin assembly, a locking tongue assembly, and a driving assembly installed on the locking body. The top of the locking pin assembly extends into the rope ladder between the steps of the rope ladder in the rope ladder channel. The driving assembly drives the locking tongue assembly to lock and unlock the locking pin assembly. In the locked state, the locking pin assembly can only swing in one direction, and the rope ladder can only pass through the rope ladder channel in one direction. In the unlocked state, the locking pin assembly can swing in both directions, and the rope ladder can pass through the rope ladder channel in both directions.

[0027] Preferably, the locking pin assembly includes a locking pin and a locking support; the locking support is installed on one side of the rope ladder channel; the root of the locking pin is hinged to the locking support, and the top of the locking pin extends between the steps of the rope ladder, allowing the locking pin to swing freely on the locking support; the locking tongue assembly includes a locking tongue and a guide groove; the guide groove is located on one side of the rope ladder channel, and the locking tongue is installed in the guide groove and can extend and retract; when the locking tongue extends out of the guide groove, it can unidirectionally block the swing of the locking pin.

[0028] This solution also provides a winch-type umbrella-shaped wind power generation system, including a main cable, a lifting guide body, a ground winch, a ground generator set, and the aforementioned winch-type umbrella-shaped wind energy conversion device. After the winch-type umbrella-shaped wind energy conversion device opens, it pulls the main cable upward, and the main cable pulls the ground winch to rotate, thereby driving the ground generator set to generate electricity.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] This solution utilizes a combination of a traditional drum and a motor to differentiate the timing of rope retraction and release between the first cable located at the edge of the umbrella canopy and the second cable located at the top of the umbrella canopy, enabling the working umbrella to open and close with the help of wind power. By locking the release of the first cable at appropriate times, the working umbrella can be kept in an open or closed state. This solves the problem of opening and closing umbrella-type wind energy conversion devices, achieving a simple, efficient, and reliable result.

[0031] This solution uses a first drum and a second drum to hold two cables respectively. When the switching component switches states, the first drum and the second drum are dynamically coupled to the winch shaft in a timely manner, so that the first drum and the second drum can wind up and unwind their respective cables separately or simultaneously.

[0032] This solution achieves a stable and reliable locking effect by using the shape matching between the locking pin assembly and the rope ladder steps, as well as the unidirectional restriction of the locking pin assembly's swing by the locking tongue assembly, to ensure that the rope ladder can be locked in one direction.

Detailed Implementation

[0052] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0053] like Figures 1 to 6 As shown, this technical solution is a winch-type umbrella-shaped wind energy opening and closing method, wherein one end of the first cable 21 is wound onto the first drum 120, and the other end is tied to the edge of the umbrella surface of the working umbrella 10; one end of the second cable 22 is wound onto the second drum 130, and the other end is tied to the top of the umbrella surface of the working umbrella 10; including the following stages:

[0054] During the ascent phase, the high-altitude wind energy drives the power parachute 10 to rise, the first cable 21 and the second cable 22 are released, the first cable 21 pulls the first drum 120 to rotate, and the second cable 22 pulls the second drum 130 to rotate; the power parachute 10 stops after rising to a certain height.

[0055] During the closing phase, the working umbrella 10 continues to rise to the first height H1, the first cable 21 continues to release the cable, the second cable 22 stops releasing the cable, the edge of the canopy of the working umbrella 10 continues to rise and folds upward, and the working umbrella 10 closes.

[0056] During the descent phase, the motor drives the first drum 120 and the second drum 130 to rotate simultaneously, and the first cable 21 and the second cable 22 are wound up. The first drum 120 winds up the first cable 21, and the second drum 130 winds up the second cable 22. The first cable 21 and the second cable 22 pull the power umbrella 10 down; the power umbrella 10 stops after descending to a certain height.

[0057] During the opening phase, the power umbrella 10 continues to descend to the second height H2. The first cable 21 continues to be wound up, while the second cable 22 stops being wound up. The edge of the canopy of the power umbrella 10 continues to descend and folds downward, and the power umbrella 10 opens.

[0058] The first cable 21 can only be released after it has been unlocked.

[0059] The winch-type umbrella-shaped wind power opening and closing method of this scheme is applicable to the above-mentioned high-altitude wind power generation system of ground power generation type. The first drum 120, the second drum 130, and the motor are all fixed to the main cable 20. The working umbrella 10 is opened and closed by the traction control of the first cable 21 and the second cable 22. After the working umbrella 10 completes its opening in the air and remains stable, it can pull the main cable 20 upward, thereby driving the ground generator to generate electricity. The opening and closing method of this scheme specifically includes the following stages:

[0060] During the ascent phase, wind power drives the parachute 10 upwards, unlocking the first cable 21 to release it. The parachute 10 then pulls the first cable 21 and the second cable 22 upwards. The first cable 21 pulls the first drum 120 to rotate, and the second cable 22 pulls the second drum 130 to rotate. After the parachute 10 reaches a certain height, the first cable 21 is locked, releasing the remaining cable and tightening the parachute 10, stopping its ascent. At this point, the parachute 10 has completed its deployment in the air and remains stable, allowing it to send a signal indicating that deployment is complete.

[0061] During the closing phase, upon receiving the closing signal, the first cable 21 is unlocked and released, allowing the wind-driven power parachute 10 to continue rising to the first height H1. The second drum 130 stops rotating, the second cable 22 stops releasing and tightens the top of the parachute 10's canopy; the wind-driven edge of the parachute 10's canopy continues to rise and folds upwards, the first cable 21 continues releasing, and the first drum 120 continues rotating until the parachute 10 is fully closed. After the parachute 10 is closed, the first cable 21 is locked and released.

[0062] During the descent phase, the motor starts and drives the first drum 120 and the second drum 130 to rotate simultaneously. The first drum 120 winds up the first cable 21, and the second drum 130 winds up the second cable 22. The first cable 21 and the second cable 22 simultaneously pull the closed parachute 10 downwards. After the parachute 10 descends to a certain height, the motor shuts off, the first cable 21 and the second cable 22 stop winding, and the parachute 10 stops descending. At this point, the parachute 10 has closed in the air and can send a signal indicating that it has closed.

[0063] During the opening phase, upon receiving the opening signal, the motor restarts, and the first cable 21 and the second cable 22 simultaneously pull the closed parachute 10 to continue descending to the second height H2. The second drum 130 stops rotating, the second cable 22 stops winding, and wind power drives the top of the parachute 10 upwards; simultaneously, the motor continues to drive the first drum 120 to rotate, the first cable 21 continues winding and pulls the edge of the parachute 10 downwards, folding it down, thus completing the opening of the parachute 10. After the parachute 10 opens, the motor shuts off, the first drum 120 stops rotating, and the first cable 21 stops winding.

[0064] This solution utilizes the differentiated timing of rope retraction and release between the first cable 21 located at the edge of the umbrella surface and the second cable 22 located at the top of the umbrella surface. By employing a traditional combination of drum and motor, the working umbrella 10 is opened and closed using wind power. Furthermore, by locking the release of the first cable 21 at appropriate times, the working umbrella 10 can maintain its open and closed state. This solution solves the opening and closing problem of the umbrella-type wind energy conversion device, achieving a simple, efficient, and reliable result.

[0065] Preferably, the system also includes a locking mechanism 50. In the locked state, the first cable 21 can only be wound up; in the unlocked state, the first cable 21 can be wound up and unwound. This solution ensures that the first cable 21 can only be unwound after the locking mechanism 50 is released. As can be seen from the four stages described above, the first cable 21 only needs to be locked to prevent unwinding, not to prevent winding up. Therefore, the locking mechanism 50 can be designed as a one-way locking mechanism, meaning that in the locked state, winding up is allowed while winding up is locked; in the unlocked state, both winding up and unwinding are allowed. Compared to a two-way locking mechanism, when the first cable 21 is wound up, the locking mechanism 50 does not require energy to unlock, thus reducing the power generation system's own losses and improving its power generation efficiency.

[0066] Furthermore, the locking mechanism 50 is located between the power umbrella 10 and the first drum 120, and the first cable 21 is connected in series with the locking mechanism 50 and then wound onto the first drum 120. In this scheme, wind power drives the power umbrella 10 to rise, and the first cable 21 transmits tension to pull the main cable 20 to rise and generate electricity. For large power umbrellas 10, in order to reliably lock the first cable 21 and transmit greater tension, the locking mechanism 50 needs to be separately set between the power umbrella 10 and the first drum 120. After the first cable 21 is connected to the edge of the umbrella surface of the power umbrella 10, it first passes through the locking mechanism 50 and then is wound onto the first drum 120.

[0067] Preferably, the edge of the umbrella canopy 10 is attached to the first cable 21; one point is connected to the main cable 20 via a roller 30, allowing the umbrella 10 to rise and fall along the main cable 20. In this design, the edge of the umbrella canopy is fixedly connected to the first cable 21, while one point is movably connected to the main cable 20. This restricts the movement of the umbrella 10 along the main cable 20, maintaining a better aerial posture; it also allows the umbrella 10 to rotate around the main cable 20 under wind force when opening and closing, making opening and closing easier, more efficient, and more reliable. Using the roller 30 for the movable connection reduces wear between the edge of the umbrella canopy 10 and the main cable 20.

[0068] In some embodiments, the locking mechanism is located on the shaft of the first drum. In the locked state, the first drum can only rotate in one direction and can only wind up the first cable. In the unlocked state, the first drum can rotate in both directions and can wind up and unwind the first cable. Specifically, the locking mechanism may be a ratchet mechanism.

[0069] In some embodiments, one end of the first cable is connected to the edge of the umbrella canopy via multiple thin ropes. The center of the top of the umbrella canopy is connected to the main cable via a roller or sleeve, and the umbrella rises and falls along the main cable.

[0070] Example 1

[0071] like Figures 7 to 12 As shown, this embodiment is a double-drum cable winch device, including a winch body 110 and a first drum 120, a second drum 130, a winch shaft 140, and a switching assembly 150 mounted on the winch body 110. The first drum 120, the switching assembly 150, and the second drum 130 are sequentially arranged side by side on the winch shaft 140. When the switching assembly 150 is switched to a first state, the first drum 120 and the winch shaft 140 rotate synchronously. When the switching assembly 150 is switched to a second state, the second drum 130 and the winch shaft 140 rotate synchronously. When the switching assembly 150 is switched to an intermediate state, the first drum 120, the second drum 130, and the winch shaft 140 rotate synchronously.

[0072] In this design, the first drum 120 and the second drum 130 can each rotate freely on the hoisting shaft 140. The switching component 150 has three states: In the first state, the switching component 150 is connected to the first drum 120, so the first drum 120 rotates synchronously with the hoisting shaft 140, and the first drum 120 independently winds up and unwinds the first cable; In the second state, the switching component 150 is connected to the second drum 130, so the second drum 130 rotates synchronously with the hoisting shaft 140, and the second drum 130 independently winds up and unwinds the second cable; In the intermediate state, the switching component 150 is connected to both the first drum 120 and the second drum 130, so the first drum 120 and the second drum 130 rotate synchronously with the hoisting shaft 140, and the first drum 120 and the second drum 130 simultaneously wind up and unwind the first and second cables. This solution uses a first drum 120 and a second drum 130 to accommodate two cables respectively. When the switching component 150 switches states, the first drum 120 and the second drum 130 are dynamically coupled with the winch shaft 140 in a timely manner, so that the first drum 120 and the second drum 130 can wind up and unwind their respective cables separately or simultaneously.

[0073] like Figures 9 to 11 As shown, preferably, the switching assembly 150 includes a first gear 151, a second gear 152, a third gear 153, a gear ring 154, a shift fork 155, and a linear drive; the first gear 151 is fixed to one side of the first drum 120, the second gear 152 is fixed to one side of the second drum 130, the third gear 153 is fixed to the middle of the winch shaft 140, and the gear ring 154 is sleeved on the outside of the third gear 153; the linear drive pushes the shift fork 155 to move the gear ring 154, so that the first gear 151, gear ring 154, and third gear 153 mesh with each other, or the second gear 152, gear ring 154, and third gear 153 mesh with each other, or the first gear 151, second gear 152, gear ring 154, and third gear 153 mesh with each other.

[0074] In this design, the first gear 151 rotates synchronously with the first drum 120, the second gear 152 rotates synchronously with the second drum 130, and the third gear 153 rotates synchronously with the hoist shaft 140. The gear ring 154 can mesh with the first gear 151, the second gear 152, or the third gear 153. When the shift fork 155 moves the gear ring 154 to the first position, the first gear 151, the gear ring 154, and the third gear 153 mesh with each other, causing the first drum 120 to rotate synchronously with the hoist shaft 140. When the shift fork 155 moves the gear ring 154 to the second position, the second gear 152, the gear ring 154, and the third gear 153 mesh with each other, causing the second drum 130 to rotate synchronously with the hoist shaft 140. When the shift fork 155 moves the gear ring 154 to the middle position, the first gear 151, the second gear 152, the gear ring 154, and the third gear 153 mesh with each other, causing the first drum 120, the second drum 130, and the hoisting shaft 140 to rotate synchronously. The switching assembly 150 in this design achieves power coupling between the first drum 120, the second drum 130, and the hoisting shaft 140 through the shift fork 155 and gear meshing, offering advantages such as high reliability and high transmission efficiency.

[0075] In some embodiments, the switching component may also be an existing multi-plate electronically controlled clutch, with multiple shaft ends connected to the first drum, the second drum, and the winch shaft, respectively.

[0076] Furthermore, the linear drive component includes a switching motor 156 and a linkage mechanism 157; the switching motor 156 is fixed to the winch body 110; the linkage mechanism 157 connects the switching motor 156 and the shift fork 155, and the linkage mechanism 157 is used to convert the rotational motion of the switching motor 156 into the linear motion of the shift fork 155. The switching motor 156 is preferably a stepper motor to achieve precise position control of the shift fork 155. The linkage mechanism 157 is a crank-slider mechanism.

[0077] In some embodiments, the linear drive can also be an existing linear motor or electric cylinder, whose output shaft is directly connected to the shift fork.

[0078] Furthermore, the surface of the toothed ring 154 is provided with an annular groove, the shape of which is adapted to the shape of the shift fork 155. The shift fork 155 moves the toothed ring 154 between a first position, an intermediate position, and a second position through the annular groove.

[0079] Preferably, the system also includes a motor 160 and a transmission assembly 170; the motor 160 is fixed to one side of the winch body 110; the transmission assembly 170 is installed at one end of the winch shaft 140, and the transmission assembly 170 connects the motor 160 and the winch shaft 140.

[0080] Furthermore, the transmission assembly 170 includes a fourth gear 171 and a fifth gear 172 that mesh with each other. The fourth gear 171 is connected to one end of the winch shaft 140, and the fifth gear 172 is connected to one end of the motor 160. The fourth gear 171 has a greater number of teeth than the fifth gear 172. By designing different numbers of teeth, the transmission assembly 170 in this solution can reduce the rotational speed of one end of the winch shaft 140 and increase the torque during the cable winding stage, thereby providing a slow but powerful winding force.

[0081] In some embodiments, the transmission component may also be a belt drive or a chain drive that includes a transmission ratio.

[0082] Optionally, a guide assembly 180 is also included. The guide assembly 180 is installed on the hoist body 110 at the cable entry and exit positions. The guide assembly 180 is used to guide and correct the attitude of the cable during winding and unwinding of the first drum 120 or the second drum 130. The guide assembly 180 is particularly suitable for cases where the cable is a flat strip. After the cable is unwound, it is easy to twist around its own axis under the interference of tangential external force. If it is directly wound into the drum, the cable will be messy and overlapping, increasing the space after the drum is wound; at the same time, it will also cause the cable to bend and entangle, reducing its service life. The addition of the guide assembly 180 can first straighten the cable, so that the cable is wound and unwound in the same attitude (front or back).

[0083] Preferably, the hoist body 110 is a box body, including a first inner cavity, a middle inner cavity and a second inner cavity arranged in parallel; the first drum 120 is located in the first inner cavity, the switching component 150 is located in the middle inner cavity, and the second drum 130 is located in the second inner cavity.

[0084] Optionally, the hoist body 110 is also provided with a power cover or a transmission cover. The power cover is installed around the motor 160 to protect the motor 160; the transmission cover is installed around the transmission assembly 170 to protect the transmission assembly 170.

[0085] In this embodiment, the winch body 110 is assembled from aluminum alloy sheets using fasteners to form a housing, achieving a lightweight effect. The winch shaft 140 is centrally mounted on the axis of the winch body 110 via bearings, allowing it to rotate freely and transmit power. The first drum 120 and the second drum 130 are also respectively mounted on the winch shaft 140 via bearings, distributed in the first and second inner cavities of the winch body 110.

[0086] In this embodiment, the first gear 151, the second gear 152, the third gear 153, and the gear ring 154 all have the same number of teeth and module. The first gear 151 is located on the side of the first drum 120 near the central cavity, the second gear 152 is located on the side of the second drum 130 near the central cavity, and the third gear 153 is located between the central cavity and the first gear 151 and the second gear 152. The shift fork 155 is located on one side of the gear ring 154, and one end of the shift fork 155 is inserted into the annular groove of the gear ring 154. The switching motor 156 is mounted on the wall of the central cavity, and the linkage mechanism 157 connects the switching motor 156 and the shift fork 155.

[0087] In this embodiment, the motor 160 is mounted on an extension plate on one side of the winch body 110. The fourth gear 171 and the fifth gear 172 are located on the same side.

[0088] In this embodiment, the guide assembly 180 consists of vertical rollers 181 and horizontal rollers 182 arranged in a "U" shape. The spacing between the vertical rollers 181 is slightly larger than the width of the cable, and the spacing between the horizontal rollers 182 is slightly larger than the thickness of the cable. The guide assembly 180 has two sets, located on the first inner cavity surface and the second inner cavity surface of the hoist body 110, respectively.

[0089] Example 2

[0090] like Figures 13 to 16 As shown, this embodiment is a rope ladder locking device, including a locking body 210 and a rope ladder channel 220, a locking pin assembly 230, a locking tongue assembly 240, and a driving assembly 250 installed on the locking body 210. The top of the locking pin assembly 230 extends into the rope ladder between the steps of the rope ladder within the rope ladder channel 220. The driving assembly 250 drives the locking tongue assembly 240 to lock and unlock the locking pin assembly 230. In the locked state, the locking pin assembly 230 can only swing in one direction, and the rope ladder can only pass through the rope ladder channel 220 in one direction. In the unlocked state, the locking pin assembly 230 can swing in both directions, and the rope ladder can pass through the rope ladder channel 220 in both directions.

[0091] In this design, the locking pin assembly 230 can swing freely around its base, and its top extends into the rope ladder channel 220. The locking tongue assembly 240 can unidirectionally restrict the swing of the locking pin assembly 230. When the rope ladder enters the rope ladder channel 220, the two steps on the rope ladder are locked by the top of the locking pin assembly 230. Continuing to drag the rope ladder in one direction will cause the rope ladder steps to swing in sequence, allowing the rope ladder to pass through the rope ladder channel 220. In the locked state, the locking tongue assembly 240 restricts the locking pin assembly 230 to swing only in one direction, so the rope ladder can only be dragged through the rope ladder channel 220 in one direction. In the unlocked state, the locking pin assembly 230 resumes bidirectional swing, so the rope ladder can be dragged through the rope ladder channel 220 in both directions. This solution achieves a stable and reliable locking effect by using the shape matching between the locking pin assembly 230 and the rope ladder steps, and by using the locking tongue assembly 240 to unidirectionally restrict the swing of the locking pin assembly 230.

[0092] Specifically, the locking post assembly 230 includes a locking post 231 and a locking support 232; the locking support 232 is installed on one side of the rope ladder channel 220; the root of the locking post 231 is hinged to the locking support 232, the top of the locking post 231 extends between the steps of the rope ladder, and the locking post 231 can swing freely on the locking support 232.

[0093] Specifically, the locking tongue assembly 240 includes a locking tongue 241 and a guide groove 242. The guide groove 242 is located on one side of the rope ladder channel 220, and the locking tongue 241 is installed within the guide groove 242 and can extend and retract. When the locking tongue 241 extends out of the guide groove 242, it can unidirectionally block the swing of the locking pin 231. When the locking tongue 241 retracts into the guide groove 242, it moves away from the locking pin 231. The locking tongue 241 is equivalent to a stop within the swing range of the locking pin 231, preventing the locking pin 231 from swinging in a certain direction, thereby achieving the aforementioned unidirectional restriction. The locking tongue 241 can be located at the root, top, or hinge axis of the locking pin 231. The guide groove 242 is used to support and guide the extension and retraction of the locking tongue 241.

[0094] In some embodiments, the latch assembly may also be an electronically controlled one-way clutch, installed at the root of the lock pin assembly, and the drive assembly is the corresponding control circuit.

[0095] Preferably, the locking support 232 and the guide groove 242 are located on both sides of the rope ladder channel 220, and the axis of the locking pin 231 and the axis of the guide groove 242 are both perpendicular to the rope ladder channel 220. When the locking tongue 241 extends out of the guide groove 242, it enters the rope ladder channel 220 and abuts against one side of the top of the locking pin 231. When the locking tongue 241 retracts into the guide groove 242, it leaves the rope ladder channel 220 and moves away from the locking pin 231. The pin assembly 230 and the tongue assembly 240 are distributed along both sides of the rope ladder channel 220, which helps to balance the weight on both sides of the rope ladder channel and avoid one side of the device being unbalanced. The perpendicular arrangement of the axes of the locking pin 231 and the guide groove 242 helps to maximize the locking force of the rope ladder.

[0096] In some embodiments, the locking pin assembly and the locking tongue assembly may also be arranged on the same side, as long as the locking tongue can provide unidirectional obstruction to the locking pin. Furthermore, when the locking tongue is retracted into the guide groove (unlocked state), it should avoid interfering with the rope ladder passing through the rope ladder channel.

[0097] Specifically, the drive assembly 250 includes a power component 251 and a connecting rod 252; the connecting rod 252 has a first inclined surface that abuts against the bottom of the locking tongue 241; the power component 251 pushes the connecting rod 252 to move, and the first inclined surface pushes the locking tongue 241 to extend or retract into the guide groove 242. This solution utilizes inclined surface transmission to amplify the thrust output by the power component 251 and convert the thrust direction to the extension and retraction direction of the locking tongue 241, thereby reducing the size of the power component 251 and reducing the layout restrictions of the drive assembly 250 on the locking body 210.

[0098] Furthermore, a roller 243 is provided at the bottom of the locking tongue 241. The first inclined surface pushes the locking tongue 241 out of or retract into the guide groove 242 via the roller 243. The roller 243 is used to reduce the frictional force between the first inclined surface and the locking tongue 241, thereby reducing surface wear.

[0099] Furthermore, the drive assembly 250 also includes a slider 253 and a guide rail 254. The slider 253 is connected to one side of the connecting rod 252, and the guide rail 254 is mounted on the locking body 210. The slider 253 is sleeved on the guide rail 254 and moves with the connecting rod 252. The slider 253 and the guide rail 254 provide support for the connecting rod 252, transmitting the force on the connecting rod 252 to the locking body 210, thus improving the force distribution on the power component 251. They also provide guidance for the connecting rod 252, preventing positional deviation during movement.

[0100] Preferably, the locking post assembly 230 further includes a first spring 233, which is disposed at the root of the locking post 231. The first spring 233 is used to automatically reset the locking post 231 after swinging. The locking tongue assembly 240 further includes a second spring 244, which is disposed at the bottom of the guide groove 242. The second spring 244 is used to automatically reset the locking tongue 241 after the connecting rod 252 is disengaged.

[0101] Preferably, the rope ladder channel 220 includes two sets of C-shaped tracks 221 with openings facing each other and a sheath 222, with the sheath 222 located at both ends of the C-shaped tracks 221; the two sides of the rope ladder are guided through the C-shaped tracks 221 via the sheath 222. The sheath 222 is made of a material with wear resistance and a low coefficient of friction. The sheath 222 guides the rope ladder, reducing the friction between the rope ladder and the C-shaped tracks 221, and reducing wear on both the rope ladder and the C-shaped tracks 221.

[0102] Furthermore, the C-shaped track 221 has an inwardly rolled edge 223 on the open side. The inwardly rolled edge 223 partially blocks the two sides of the rope ladder, preventing the rope ladder from shifting laterally and leaving the rope ladder channel 220 when passing through.

[0103] Optionally, a guide block 224 is provided on the open side of the C-shaped track 221, extending between the steps of the rope ladder. The guide block 224 allows the steps of the rope ladder to move freely as it passes through the C-shaped track 221. The guide block 224 is deeper than the inwardly rolled edge 223, providing better blocking and preventing the rope ladder from shifting laterally or leaving the rope ladder channel 220. Simultaneously, the swingable design of the guide block 224 allows the rope ladder steps to move freely, enabling the rope ladder to pass freely through the C-shaped track 221.

[0104] Optionally, the guide block 224 is equipped with a counting sensor to obtain the number of times the guide block 224 swings when the rope ladder passes by. When the rope ladder passes by, each rope ladder step causes the guide block 224 to swing once, and the interval between the rope ladder steps is a fixed length. Therefore, the length of the rope ladder passing through the rope ladder channel = the interval between the steps × the number of swings.

[0105] In this embodiment, the locking pin 231 of the locking pin assembly 230 is a cylinder with rounded corners at its top edge to allow the rope ladder steps to move more smoothly. The locking support 232 is a double support, mounted on the locking body 210, and hinged to the locking pin 231 from both sides. The first spring 233 is a compression spring, connecting the root of the locking pin 231 to the locking support 232.

[0106] In this embodiment, the top of the locking tongue 241 of the locking tongue assembly 240 is provided with an arc-shaped side surface, so that when the locking tongue 241 is extended, it makes arc-shaped contact with the top side surface of the locking pin 231, thereby improving the stress distribution. Rollers 243 are respectively provided at both ends of the bottom of the locking tongue 241. The second spring 244 is a compression spring and is disposed in the guide groove 242 at the bottom of the locking tongue 241.

[0107] In this embodiment, the power component 251 of the drive assembly 250 is an electric cylinder, mounted on the locking body 210, located on the same side of the latch assembly 240. The connecting rod 252 is a double-fork rod, one end of which is hinged to the power component 251, and the other end is provided with two separate first inclined surfaces. The position of the first inclined surfaces corresponds to the position of the roller 243. Correspondingly, the slider 253 and the guide rail 254 are also configured in two sets. The first inclined surfaces face away from the rope ladder channel 220.

[0108] In this embodiment, the locking body 210 is a frame made of aluminum alloy sheet using fasteners to achieve a lightweight effect. The guide block 224 of the rope ladder channel 220 is a cross block or a straight block, the diameter or length of which is slightly equal to the opening width of the C-shaped track 221. The counting sensor is installed at the rotating end of the straight block.

[0109] The working process of this embodiment is as follows: The rope ladder locking device is in the locked state by default. The locking tongue 241 extends out of the guide groove 242 under the push of the second spring 244, enters the rope ladder channel 220, and abuts against one side of the top of the locking post 231, blocking the swing of the locking post 231 in one direction. The rope ladder can only pass through the rope ladder channel 220 in one direction. After receiving the unlocking signal, the power component 251 pushes the connecting rod to move. The two first inclined surfaces at one end of the connecting rod simultaneously push the locking tongue 241 back into the guide groove 242 through the roller 243. After the locking tongue 241 leaves the rope ladder channel 220 and moves away from the locking post 231, the locking post 231 can swing in both directions, and the rope ladder can pass through the rope ladder channel 220 in both directions.

[0110] Example 3

[0111] like Figures 1 to 16 As shown, this embodiment is a winch-type umbrella-shaped wind power generation system, including a main cable 20, a lifting guide body 40, a ground winch 60, a ground generator set, and a winch-type umbrella-shaped wind energy conversion device using embodiments 1 and 2. After the winch-type umbrella-shaped wind energy conversion device opens, it pulls the main cable 20 upward, and the main cable 20 pulls the ground winch 60 to rotate, thereby driving the ground generator set to generate electricity.

[0112] The winch-type umbrella-shaped wind energy conversion device is fixed on the main cable 20 and includes a rope ladder 23, a rope ladder locking device, and a double-drum cable winch device; the rope ladder locking device is the locking mechanism 50.

[0113] One end of the main cable 20 is wound onto a ground winch 60, and the other end is suspended in the air via a lift guide 40. The ground winch 60 is connected to a ground generator set. The lift guide 40 provides lift to the main cable 20 and the equipment fixed to it. One edge of the umbrella canopy of the working umbrella 10 is connected to the main cable 20 via a roller 30, while the remaining edge is attached to the first cable 21; the top of the umbrella canopy is attached to the second cable 22. A short section of the first cable 21 is connected to a rope ladder 23, which passes through the rope ladder channel 220 of the rope ladder locking device. The first cable 21 is wound onto the first drum 120 of the double-drum cable winch. The second cable 22 is wound onto the second drum 130 of the double-drum cable winch. The double-drum cable winch, the rope ladder locking device, and the working umbrella 10 are arranged sequentially from bottom to top on the main cable 20.

[0114] Optionally, multiple winch-type umbrella-shaped wind energy conversion devices are sequentially installed on the main cable from bottom to top.

[0115] In some embodiments, the first cable is a rope ladder, and the first drum is wider to accommodate winding up the rope ladder.

[0116] The working process of this embodiment is as follows:

[0117] During the ascent phase, high-altitude wind energy drives the power umbrella 10 to rise. The drive assembly 250 pushes the locking tongue assembly 240 via the inclined plane to unlock the locking column assembly 230. The power umbrella 10 pulls the first cable 21 and the second cable 22 to rise, and the rope ladder 23 passes through the rope ladder channel 220. The first cable 21 pulls the first drum 120 to rotate, and the second cable 22 pulls the second drum 130 to rotate. After the power umbrella 10 rises to a certain height, the drive assembly 250 disengages from the locking tongue assembly 240 to lock the locking column assembly 230. The rope ladder 23 is then engaged within the rope ladder channel 220, and the first cable 21 tightens the power umbrella 10, stopping its ascent. At this point, the power umbrella 10 has completed its opening in the air and remains stable. The winch-type umbrella-shaped wind energy conversion device sends a signal to the controller indicating that the opening is complete.

[0118] During the power generation phase, the main cable 20 is released, and the high-altitude wind energy drives the power umbrella 10 to continue rising. The power umbrella 10 transmits tension to the main cable 20 through the first cable 21, the rope ladder 23, and the ladder rope locking device. The main cable 20 pulls the ground winch 60 to rotate, thereby driving the ground generator to generate electricity. When the power umbrella 10 rises to the third height H3, the main cable 20 reaches the release limit, the ground winch 60 stops rotating, and the controller sends a closing signal to the winch-type umbrella-type wind energy conversion device.

[0119] During the umbrella-closing phase, upon receiving the umbrella-closing signal, the drive assembly 250 unlocks the rope ladder 23, the first cable 21 releases its rope, and the high-altitude wind energy drives the working umbrella 10 to continue rising to the first height H1. The switching assembly 150 switches to either the first or second state, and the first drum 120 and the second drum 130 rotate independently. When the second cable 22 reaches its release limit, the second drum 130 stops rotating, the second cable 22 stops releasing its rope, and tightens the top of the working umbrella 10's canopy. The edge of the working umbrella 10's canopy continues to rise and folds upwards, the first cable 21 continues releasing its rope, and the first drum 120 continues rotating until the working umbrella 10 is fully closed. After the working umbrella 10 is closed, the drive assembly 250 locks the rope ladder 23, the first cable 21 also reaches its release limit, and the first cable 21 stops releasing its rope.

[0120] During the descent phase, the switching component 150 switches to the intermediate state, the motor 160 starts, and drives the winch shaft 140 to rotate via the transmission component 170. The first drum 120, the second drum 130, and the winch shaft 140 rotate simultaneously. The first drum 120 winds up the first cable 21, and the second drum 130 winds up the second cable 22; the first cable 21 and the second cable 22 simultaneously pull the closed parachute 10 downwards. After the parachute 10 descends to a certain height, the motor 160 shuts off, the first cable 21 and the second cable 22 stop winding, and the parachute 10 stops descending. At this point, the parachute 10 closes in mid-air, and the winch-type umbrella-type wind energy conversion device sends a signal to the controller indicating that the parachute closure is complete.

[0121] During the recovery phase, the main cable 20 is wound up, and the ground winch 60 starts and winds up the main cable 20. The main cable 20 pulls the closed power umbrella 10 down. When the power umbrella 10 descends to the fourth height H4, the main cable 20 reaches the winding limit, the ground winch 60 stops rotating, and the controller sends an opening signal to the winch-type umbrella wind energy conversion device.

[0122] During the opening phase, upon receiving the opening signal, the winch-type umbrella-shaped wind energy conversion device restarts the motor 160, and the first cable 21 and the second cable 22 simultaneously pull the closed working umbrella 10 to continue descending to the second height H2. The switching component 150 switches to the first state. When the second cable 22 reaches the winding limit, the second drum 130 stops rotating, and the second cable 22 stops winding. High-altitude wind energy drives the top of the umbrella surface of the working umbrella 10 to move upward; simultaneously, the motor 160 continues to drive the first drum 120 to rotate, the first cable 21 continues to wind and pulls the edge of the umbrella surface of the working umbrella 10 to continue descending and folding downward, thus completing the opening of the working umbrella 10. After the working umbrella 10 is opened, the motor 160 shuts off, the first cable 21 reaches the winding limit, the first drum 120 stops rotating, and the first cable 21 stops winding.
