Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a wired tethered unmanned aerial vehicle high-altitude base station and a usage method thereof. Background Art

[0002] In the field work environment or at the scene of a disaster accident, there are often situations of large-area communication, power and road interruptions. Ordinary emergency communication means cannot be quickly restored, which brings many inconveniences to field work or disaster relief operations. Therefore, currently, unmanned aerial vehicles are usually used to carry communication relay base station antennas to maintain the height and signal range of the base station and support large-scale communication work in the surrounding area. However, the payload of the unmanned aerial vehicle is small, resulting in a limited weight of the battery it can carry. Therefore, the flight time of the unmanned aerial vehicle after carrying the base station is limited, and it needs to take off and land frequently for charging or battery replacement, making it difficult to provide stable base station signal support for a long time.

[0003] The patent with the application number CN201620461102.8 discloses a tethered unmanned aerial vehicle wire hanging device and a tethered unmanned aerial vehicle, including an unmanned aerial vehicle connection part, a ball joint structure and a wire hanging part; the ball joint structure includes a ball joint and a slider. The ball joint is used to connect the unmanned aerial vehicle connection part and the slider, so that the unmanned aerial vehicle connection part and the slider can rotate in all directions; the wire hanging part is fixed on the outer side wall of the slider; a wire groove for accommodating a cable is opened on the wire hanging part, so that the cable can be connected to the unmanned aerial vehicle and the workstation along the wire groove. In the above technical solution, the ball joint and the slider in the ball joint structure are connected by a surface contact method, with the effect of multi-angle rotation, which can make the wire hanging part rotate at multiple angles relative to the connected unmanned aerial vehicle. The cable for supplying power to the unmanned aerial vehicle is placed in the wire groove of the wire hanging part, and a buffering effect is given to the cable through the multi-angle rotation effect between the wire hanging part and the unmanned aerial vehicle, reducing the impact tension caused by the sudden change of the motion state of the unmanned aerial vehicle on the cable and slowing down the damage at the joint of the cable and the unmanned aerial vehicle.

[0004] However, it only sets a buffering structure in the unmanned aerial vehicle part, and the buffering effect is relatively general. In the case of the unmanned aerial vehicle being interfered by strong winds or the like, the cable is easily subjected to an instantaneous tensile force and breaks or causes other safety accidents, and the overall reliability and safety of the equipment are relatively low. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a wired tethered unmanned aerial vehicle high-altitude base station and a usage method thereof, so as to solve the problem that the current tethered unmanned aerial vehicle only sets a buffering structure in the unmanned aerial vehicle part, the buffering effect is relatively general, in the case of the unmanned aerial vehicle being interfered by strong winds or the like, the cable is easily subjected to an instantaneous tensile force and breaks or causes other safety accidents, and the overall reliability and safety of the equipment are relatively low.

An annular rotating groove is arranged at the top end of the annular storage groove;

[0009] A rotating guide frame is fitted and rotatably arranged inside the annular rotating groove. An arc-shaped fitting groove is arranged in the middle of the rotating guide frame. An arc-shaped lead frame is fitted and slidably arranged inside the arc-shaped fitting groove. A lead sleeve is vertically arranged in the middle of the arc-shaped lead frame. An inclined rotating shaft is horizontally arranged in the middle of the lead sleeve. The lead sleeve is rotationally connected to the arc-shaped lead frame through the inclined rotating shaft. Return springs are arranged on both the front and rear sides of the arc-shaped lead frame;

[0010] An annular support frame is arranged above the rotating guide frame. The outer end of the annular support frame is fixedly arranged on the inner wall of the electrical equipment bin. A central connecting sleeve is vertically arranged at the center of the annular support frame. A central traction sleeve is nested and rotatably arranged inside the central connecting sleeve. A plurality of clamping rollers are evenly arranged around the inside of the central traction sleeve;

[0011] A tethered unmanned aerial vehicle is arranged inside the unmanned aerial vehicle storage bin. An equipment carrier is arranged above the tethered unmanned aerial vehicle. A tether traction frame is arranged at the center of the lower part of the tethered unmanned aerial vehicle. The tether cables sequentially pass through the lead sleeve and the central traction sleeve and are connected to the tethered unmanned aerial vehicle through the tether traction frame.

[0012] In some alternative embodiments, the rotating guide frame is rotationally connected to the spacer sleeve through the annular rotating groove. The vertical center line of the rotating guide frame and the vertical center line of the spacer sleeve are on the same straight line. An annular gear ring is arranged around the inside of the rotating guide frame. A winding gear is meshed inside the annular gear ring.

The central connection sleeve is connected to the fixed annular support frame through a plurality of telescopic buffer rods arranged around, forming an omnidirectional movement buffer structure. Therefore, when the drone pulls the tether cable under the action of environmental factors such as wind, the tether cable can drive the central connection sleeve to move and buffer through the central traction sleeve, so as to avoid the tether cable being broken due to excessive instantaneous tensile force. And because the telescopic buffer rods are connected to the annular support frame and the central connection sleeve through the connecting ball heads of the universal connection structure, the central connection sleeve can move and buffer in any direction around, and can also perform a certain movement buffer in the longitudinal height, so as to facilitate buffering the tether cable when the tethered drone is pulled by tensile forces in different directions and angles, which is beneficial to improving the overall reliability and safety of the equipment.

[0017] In some alternative embodiments, shielding and sealing covers are symmetrically arranged above the drone storage bin. The shielding and sealing covers are of semi-circular structure. A vertical rotating shaft is arranged at the outer end of the shielding and sealing cover. The shielding and sealing cover is rotatably connected to the mooring control base through the vertical rotating shaft. The symmetrically arranged shielding and sealing covers can rotate and close to each other through the vertical rotating shaft to completely cover and seal the drone storage bin. A rotating gear is arranged at the shaft end of the vertical rotating shaft. A driving gear is meshed on the outside of the rotating gear.

Spaced balls are rotatably embedded at the bottom surface of the semi-circular closing plate. The bottom surface of the semi-circular closing plate is slidably connected to the top surface of the shielding and sealing cover through the spaced balls. A plurality of reset tension springs are arranged around the lower side of the semi-circular connecting sleeve. An elastic sealing sleeve is arranged around the outer edge of the semi-circular closing plate.

[0019] In some alternative embodiments, a plurality of horizontal arms are arranged on the outside of the moored drone. A power motor is arranged at the outer end of the horizontal arm. A propeller is arranged at the shaft end of the power motor. An inclined folding frame is arranged on the lower side of the horizontal arm. A base station antenna is arranged in the middle of the inclined folding frame. The bottom end of the inclined folding frame is inclined towards the center of the moored drone.

[0020] In some alternative embodiments, a folding rotating shaft is arranged at the top end of the inclined folding frame.

A contact roller is arranged at the bottom end of the inclined folding frame. An arc-shaped guide plate is arranged around the edge of the horizontal takeoff and landing platform. When the moored drone descends to the drone storage bin, the inclined folding frame is in contact and guided to slide through the contact roller and the arc-shaped guide plate to push the inclined folding frame to rotate and fold inwards.

[0021] A method for using a high-altitude base station of a wired tethered unmanned aerial vehicle, comprising the following steps:

[0022] L1 Cabin Deployment: Drive the shielding and sealing cover to rotate outward through the vertical rotating shaft, so that the tethered unmanned aerial vehicle in the unmanned aerial vehicle storage compartment is completely exposed. The tethered unmanned aerial vehicle starts to rise and increase its height. At the same time, the expansion spring drives the inclined folding frame and the base station antenna to rotate outward to a fixed angle to maintain the best communication angle and range of the base station antenna;

[0023] L2 UAV Takeoff: The tethered unmanned aerial vehicle continuously increases its height. The tethered cable passes through the lead sleeve and the central traction sleeve in sequence and is connected to the tethered unmanned aerial vehicle through the tethered traction frame. The rotating guide frame rotates along the annular rotating groove to drive the lead sleeve thereon to rotate synchronously, and guides and pulls out the tethered cable conductor placed in the annular storage groove to release the tethered cable synchronously according to the climb of the tethered unmanned aerial vehicle;

[0024] L3 Constant Altitude Operation: The tethered unmanned aerial vehicle climbs to the required height. The tethered unmanned aerial vehicle provides a wide range of communication support through electronic devices such as the base antenna loaded. The tethered control base and the tethered unmanned aerial vehicle are connected through the tethered cable to provide energy and communication support for the tethered unmanned aerial vehicle and the base station;

[0025] L4 UAV Landing: The tethered unmanned aerial vehicle continuously decreases its height. The rotating guide frame rotates along the annular rotating groove to drive the lead sleeve thereon to rotate in the reverse direction, and guides and pulls the tethered cable conductor placed above into the annular storage groove to wind up the tethered cable synchronously according to the landing of the tethered unmanned aerial vehicle:

[0026] L5 Cabin Closing: When the unmanned aerial vehicle descends to the unmanned aerial vehicle storage compartment, the inclined folding frame contacts and guides and slides with the arc-shaped guide plate through the contact roller to push the inclined folding frame to rotate inward and fold, reducing the overall height of the tethered unmanned aerial vehicle for storage. Then, the shielding and sealing cover rotates through the vertical rotating shaft to close each other to completely cover and seal the unmanned aerial vehicle storage compartment to provide protection for the internal tethered unmanned aerial vehicle.

[0027] As can be seen from the above, a wired tethered unmanned aerial vehicle (UAV) high-altitude base station provided by the present invention connects the tethered UAV in the air and the tethered control base on the ground through a tether cable. The tethered UAV flying in the air can carry the antennas and electronic devices required by the base station, while the tethered control base continuously provides power and communication for the tethered UAV through the tether cable to maintain the stable endurance of the tethered UAV. The tether cable passes through the lead sleeve and the central traction sleeve in sequence and is connected to the tethered UAV through the tether traction frame. By rotating the rotary guide frame, the lead sleeve can be driven to rotate synchronously to wind and store the tether cable in the annular storage groove or release it. When the UAV is pulled by the tether cable under the action of environmental factors such as wind, the tether cable can drive the arc-shaped lead frame to slide in the arc-shaped fitting groove through the lead sleeve and buffer through the return spring, so as to avoid the tether cable from breaking due to excessive instantaneous tension and also avoid the tethered UAV from losing balance and falling due to sudden tension, which is beneficial to improving the overall reliability and safety of the equipment.

And the central traction sleeve 405 also mainly serves as an anchor point of the tether cable 204 to provide the fixing force of traction. At the same time, a plurality of clamping rollers 406 are arranged in the central traction sleeve 405, which can provide guidance for the tether cable 204 through the clamping rollers 406. And the central traction sleeve 405 is rotatably connected to the central connection sleeve 401, which is convenient for rotating at a certain angle following the movement of the tethered drone 5 and the tether cable 204, so as to avoid direct friction damage or jamming between the tether cable 204 and the central traction sleeve 405 when the tether cable 204 moves, which is beneficial to improving the smoothness and service life of the movement of the tether cable 204. The central connection sleeve 401 is connected to the fixed annular support frame 4 through a plurality of telescopic buffer rods 402 arranged around, forming an omnidirectional movement buffer structure. Therefore, when the drone pulls the tether cable 204 under the action of environmental factors such as wind, the tether cable 204 can drive the central connection sleeve 401 to move and buffer through the central traction sleeve 405, so as to avoid the tether cable 204 being broken due to excessive instantaneous tensile force. And because the telescopic buffer rod 402 is connected to the annular support frame 4 and the central connection sleeve 401 through the connecting ball heads 403 of the universal connection structure,Therefore, the central connection sleeve 401 can move and buffer in any direction around it, and can also move and buffer to a certain extent in the longitudinal height, so as to facilitate buffering for the tether cable 204 when the tethered drone 5 is subjected to tensile forces in different directions and angles, which is beneficial to improving the overall reliability and safety of the equipment.

[0056] Such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 14As shown, optionally, a traction connection ring 701 is rotatably arranged in the middle of the mooring traction frame 7. A horizontal guide rod 702 is horizontally arranged in the middle of the traction connection ring 701. A mooring traction seat 703 is arranged in the middle of the horizontal guide rod 702. A conductive slip ring 704 is arranged at the bottom of the mooring traction seat 703. The mooring cable 204 is rotatably connected to the mooring traction seat 703 through the conductive slip ring 704. A guide sliding sleeve 705 is arranged in the middle of the mooring traction seat 703. The mooring traction seat 703 is slidably connected to the horizontal guide rod 702 through the guide sliding sleeve 705. Horizontal springs 706 are arranged on both the left and right sides of the guide sliding sleeve 705. The device connects the mooring UAV 5 in the air and the mooring control base 1 on the ground through the mooring cable 204. A central traction sleeve 405 and a lead sleeve 306 are arranged on the mooring control base 1 to provide guidance and buffering for the mooring cable 204. The mooring UAV 5 is interconnected with the mooring cable 204 through the mooring traction frame 7. The mooring cable 204 is rotatably connected to the mooring traction seat 703 on the mooring traction frame 7 through the conductive slip ring 704. The conductive slip ring 704 can maintain the conduction of the connecting cables on its upper and lower sides during rotation to prevent the mooring cable 204 from being driven to rotate when the mooring UAV 5 rotates, thus avoiding the mooring cable 204 from being twisted and damaged. The mooring traction seat 703 is slidably connected to the horizontal guide rod 702 through the guide sliding sleeve 705. When the UAV is pulled by the mooring cable 204 under the action of environmental factors such as wind, the mooring traction seat 703 will move along the horizontal guide rod 702 towards the mooring cable 204 side, so that the traction point of the mooring cable 204 deviates to one side, thereby balancing the deflection and tilting force of the mooring UAV 5 and preventing the mooring UAV 5 from tilting too much under the traction of the mooring cable 204 and the action of wind and crashing. At the same time, a certain buffering force can be provided through sliding and the horizontal spring 706 to prevent the mooring cable 204 from being broken due to excessive instantaneous tension. And the greater the wind force, the greater the distance that the mooring traction seat 703 will move along the horizontal guide rod 702 towards the mooring cable 204 side, and the more the traction point of the mooring cable 204 will deviate to one side, so as to flexibly adjust and balance the deflection and tilting force of the mooring UAV 5 according to the actual situation. Moreover, the mooring traction seat 703 is interconnected with the traction connection ring 701 through the guide sliding sleeve 705 and the horizontal guide rod 702, which is convenient for adjusting the orientation of the horizontal guide rod 702 and the deflection position of the mooring traction seat 703 through the rotation of the traction connection ring 701, so that when the mooring UAV 5 is affected by wind from any direction, the mooring traction seat 703 can move in the opposite direction for balancing, making it more convenient and flexible to use.

[0057] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 15As shown, optionally, a shielding and sealing cover 8 is symmetrically arranged above the drone storage bin 101. The shielding and sealing cover 8 is of a semi-circular structure. A vertical rotating shaft 802 is arranged at the outer end of the shielding and sealing cover 8. The shielding and sealing cover 8 is rotationally connected to the mooring control base 1 through the vertical rotating shaft 802. The symmetrically arranged shielding and sealing covers 8 can rotate and close to each other through the vertical rotating shaft 802 to completely cover and seal the drone storage bin 101. A rotating gear 803 is arranged at the shaft end of the vertical rotating shaft 802. A driving gear 804 is meshed and arranged outside the rotating gear 803. A driving motor 805 is arranged at the shaft end of the driving gear 804. A circular communication port 801 is arranged in the middle of the shielding and sealing cover 8. A semi-circular closing plate 9 is arranged above the circular communication port 801. A semi-circular connecting sleeve 901 is arranged at the center of the semi-circular closing plate 9. Spaced balls 902 are rotationally and fittingly arranged on the bottom surface of the semi-circular closing plate 9. The bottom surface of the semi-circular closing plate 9 is slidably connected to the top surface of the shielding and sealing cover 8 through the spaced balls 902. A plurality of reset tension springs 903 are arranged around the lower side of the semi-circular connecting sleeve 901. An elastic sealing sleeve 904 is arranged around the outer edge of the semi-circular closing plate 9. The device is mainly divided into two parts, namely the mooring control base 1 and the moored drone 5. A drone storage bin 101 is arranged on the mooring control base 1 to park and store the moored drone 5, so as to facilitate the simultaneous movement and use of the two. The drone storage bin 101 is kept closed by the semi-circular shielding and sealing cover 8. The driving motor 805 can drive the shielding and sealing cover 8 to rotate along the vertical rotating shaft 802 through the driving gear 804 and the rotating gear 803. When the moored drone 5 is parked in the drone storage bin 101, the shielding and sealing covers 8 can rotate and close to each other through the vertical rotating shaft 802 to completely cover and seal the drone storage bin 101, thereby providing protection for the internal moored drone 5. When the moored drone 5 needs to take off, the shielding and sealing cover 8 can rotate in the reverse direction to open the drone storage bin 101, which is more convenient and fast in use. At the same time, when the moored drone 5 has completely taken off, the shielding and sealing cover 8 can be re-closed to seal the mooring control base 1 to provide protection for it. The mooring cable 204 passes through the semi-circular connecting sleeve 901, penetrates the semi-circular closing plate 9 and the shielding and sealing cover 8 to maintain the connection. When the drone deflects, the mooring cable 204 can drive the semi-circular closing plate 9 to slide on the shielding and sealing cover 8 through the semi-circular connecting sleeve 901 to flexibly adjust the position of the semi-circular connecting sleeve 901 and maintain the sealing property of the shielding and sealing cover 8 while maintaining a flexible connection.

[0058] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14As shown, optionally, a plurality of horizontal arms 501 are provided on the outer side of the tethered drone 5. A power motor 502 is provided at the outer end of the horizontal arm 501. A propeller 503 is provided at the shaft end of the power motor 502. An inclined folding frame 6 is provided on the lower side of the horizontal arm 501. A base station antenna 601 is provided in the middle of the inclined folding frame 6. The bottom end of the inclined folding frame 6 is inclined towards the center of the tethered drone 5. A folding rotating shaft 602 is provided at the top end of the inclined folding frame 6. The inclined folding frame 6 is rotatably connected to the horizontal arm 501 through the folding rotating shaft 602. An unfolding spring 603 is provided in the middle of the folding rotating shaft 602. A contact roller 604 is provided at the bottom end of the inclined folding frame 6. An arc-shaped guide plate 104 is provided around the edge of the horizontal takeoff and landing platform 102. When the tethered drone 5 descends to the drone storage bin 101, the inclined folding frame 6 is in contact and guided by the contact roller 604 and the arc-shaped guide plate 104 to slide, so as to push the inclined folding frame 6 to rotate and fold inwards. The device is mainly divided into two parts: a tethered control base 1 and a tethered drone 5. The tethered drone 5 can carry electronic devices such as antennas required by the base station, and maintain the height of the corresponding devices by flying the tethered drone 5 to provide large-range communication support. The tethered drone 5 flies by driving the propeller 503 to rotate through the power motor 502 provided on the horizontal arm 501. A base station antenna 601 is provided on each horizontal arm 501. The base station antenna 601 is connected to the horizontal arm 501 through the inclined folding frame 6 and is also slightly inclined downward with the inclined folding frame 6 to facilitate maintaining the best communication angle and range of the base station antenna 601. At the same time, when the tethered drone 5 descends to the drone storage bin 101, the inclined folding frame 6 is in contact and guided by the contact roller 604 and the arc-shaped guide plate 104 to slide, so as to push the inclined folding frame 6 to rotate and fold inwards, so that when the tethered drone 5 descends to the drone storage bin 101, the inclined folding frame 6 can drive the base station antenna 601 to rotate and fold synchronously, so as to reduce the overall height of the tethered drone 5 and facilitate its storage. When the tethered drone 5 rises, the unfolding spring 603 can drive the inclined folding frame 6 and the base station antenna 601 to rotate and unfold outwards to facilitate maintaining the best communication angle and range of the base station antenna 601, without manual disassembly and adjustment of the base station antenna 601, which is more convenient and flexible to use.

[0059] In use, first place the tether control base 1 in the required position, connect and install its corresponding pipelines and equipment. Then, drive the motor 805 to drive the vertical rotating shaft 802 to rotate through the drive gear 804 and the rotating gear 803. Further, the vertical rotating shaft 802 drives the shielding and sealing cover 8 to rotate and unfold outward, so that the tethered drone 5 in the drone storage bin 101 is completely exposed. Then, the tethered drone 5 can be started to rise and increase its height. At the same time, the unfolding spring 603 drives the inclined folding frame 6 and the base station antenna 601 to rotate and unfold outward to a fixed angle to maintain the best communication angle and range of the base station antenna 601. The tether cable 204 passes through the lead sleeve 306 and the central traction sleeve 405 in sequence and is connected to the tethered drone 5 through the tether traction frame 7. While the tethered drone 5 continuously increases its height, the winding motor 303 drives the rotating guide frame 3 to rotate along the annular rotating groove 205 through the winding gear 302 and the annular gear ring 301. The rotating guide frame 3 drives the lead sleeve 306 thereon to rotate synchronously, guiding and leading out the tether cable 204 placed in the annular storage groove 203 to release the tether cable 204 synchronously according to the climbing of the tethered drone 5. When the tethered drone 5 climbs to the required height, the tethered drone 5 can provide wide-range communication support through the electronic devices such as the base antenna loaded thereon. The tether control base 1 and the tethered drone 5 are connected through the tether cable 204 to provide energy and communication support for the tethered drone 5 and the base station. When the work is completed, the tethered drone 5 can continuously decrease its height, and the winding motor 303 drives the rotating guide frame 3 to rotate reversely along the annular rotating groove 205 through the winding gear 302 and the annular gear ring 301 to drive the lead sleeve 306 on the rotating guide frame 3 to rotate reversely, guiding and leading the tether cable 204 placed above to be stored in the annular storage groove 203 to wind up the tether cable 204 synchronously according to the landing of the tethered drone 5. When the drone descends to the drone storage bin 101, the inclined folding frame 6 contacts and slides with the arc-shaped guide plate 104 through the contact roller 604 to push the inclined folding frame 6 to rotate and fold inward, reducing the overall height of the tethered drone 5 for storage. Then, the shielding and sealing cover 8 rotates and closes through the vertical rotating shaft 802 to completely cover and seal the drone storage bin 101 to provide protection for the internal tethered drone 5.

[0060] A method for using a wired tethered drone high-altitude base station includes the following steps:

[0061] L1 Cabin Deployment: Drive the shielding and sealing cover 8 to rotate and unfold outward through the vertical rotating shaft 802, so that the tethered drone 5 in the drone storage bin 101 is completely exposed. The tethered drone 5 is started to rise and increase its height. At the same time, the unfolding spring 603 drives the inclined folding frame 6 and the base station antenna 601 to rotate and unfold outward to a fixed angle to maintain the best communication angle and range of the base station antenna 601;

[0062] L2 UAV Takeoff: The tethered UAV 5 continuously ascends. The tether cable 204 sequentially passes through the lead sleeve 306 and the central traction sleeve 405 and is connected to the tethered UAV 5 through the tether traction frame 7. The rotary guide frame 3 rotates along the annular rotating groove 205 to drive the lead sleeve 306 thereon to rotate synchronously, guiding and pulling out the conductor of the tether cable 204 placed in the annular storage groove 203 to release the tether cable 204 synchronously with the ascent of the tethered UAV 5.

[0063] L3 Constant Altitude Operation: The tethered UAV 5 ascends to the required altitude. The tethered UAV 5 provides wide-range communication support through electronic devices such as the base antenna loaded. The tether control base 1 and the tethered UAV 5 are connected through the tether cable 204 to provide energy and communication support for the tethered UAV 5 and the base station.

[0064] L4 UAV Landing: The tethered UAV 5 continuously descends. The rotary guide frame 3 rotates along the annular rotating groove 205 to drive the lead sleeve 306 thereon to rotate in the reverse direction, guiding and pulling the conductor of the tether cable 204 placed above and storing it in the annular storage groove 203 to wind up the tether cable 204 synchronously with the descent of the tethered UAV 5.

[0065] L5 Compartment Closure: When the UAV descends to the UAV storage compartment 101, the inclined folding frame 6 contacts and slides along the arc guide plate 104 through the contact roller 604 to push the inclined folding frame 6 to rotate and fold inward, reducing the overall height of the tethered UAV 5 for storage. Then, the shielding cover 8 rotates through the vertical rotating shaft 802 to close together completely to completely cover and enclose the UAV storage compartment 101, providing protection for the internal tethered UAV 5.

[0066] The tethered UAV high-altitude base station provided by the present invention connects the tethered UAV 5 in the air with the tethered control base 1 on the ground through a tether cable 204. The tethered UAV 5 flying in the air can carry the antennas and electronic devices required by the base station, while the tethered control base 1 continuously provides power and communication for the tethered UAV 5 through the tether cable 204 to maintain the stable endurance of the tethered UAV 5. The tether cable 204 is sequentially passed through the lead sleeve 306 and the central traction sleeve 405 and is connected to the tethered UAV 5 through the tether traction frame 7. By rotating the rotary guide frame 3, the lead sleeve 306 can be driven to rotate synchronously to wind and store the tether cable 204 in the annular storage groove 203 or release it. When the UAV pulls the tether cable 204 under the action of environmental factors such as wind, the tether cable 204 can drive the arc-shaped lead frame 305 to slide in the arc-shaped fitting groove 304 through the lead sleeve 306 and is buffered by the return spring 308 to avoid the tether cable 204 being broken due to excessive instantaneous tension and also avoid the tethered UAV 5 losing balance and falling due to sudden tension, which is beneficial to improving the overall reliability and safety of the equipment.
