DETAILED DESCRIPTION

[0034] The following description will be made in conjunction with the accompanying drawings. Figure 1 - The accompanying drawings Figure 11 The present application will be further described in detail.

[0035] First lifting control embodiment:

[0036] Reference Figure 1 , Figure 2 A paragliding parachute traction unmanned aerial vehicle, comprising an unmanned frame 1, a take-up and pay-off assembly 2 is installed on the unmanned frame 1, a traction rope 21 is wound on the take-up and pay-off assembly 2, a plurality of wings 3 are installed on the unmanned frame 1, a landing gear 4 is installed on the lower side of the unmanned frame 1, a pair of axial flow fans 5 are installed on the landing gear 4, a pay-off tube 6 is rotatably installed on the unmanned frame 1, the traction rope 21 passes through the pay-off tube 6, a transmission 7 is installed at one end of the pay-off tube 6 and the unmanned frame 1, the transmission 7 is electrically connected with the wings 3, the transmission 7 is used to control the rotating speed of the wings 3 to control the unmanned aerial vehicle to ascend and descend, so that the paragliding parachute automatically controls the unmanned aerial vehicle to ascend with the change of height in the process of taking off, thereby reducing manual operation, simplifying the take-off process, and enabling the pilot to focus more on the flight itself;

[0037] When the unmanned aerial vehicle is in the process of controlling the glider to rise, the unmanned aerial vehicle, the staff and the glider form a V-shaped structure, the staff and the experimenter are located at the lowest end of the V-shaped structure, and the pulling force of the unmanned aerial vehicle and the pulling force of the glider generate a resultant force to make the staff and the experimenter rise in height. A detachable connector 9 is mounted at the end of the traction rope 21 away from the take-up and pay-off assembly 2, the detachable connector 9 includes a safety belt 91 worn on the body of the flight personnel, a carabiner 92 mounted on the safety belt 91, and a locking assembly 93 mounted on the traction rope 21, and the locking assembly 93 cooperates with the carabiner 92 to realize the separation and connection of the safety belt 91 and the traction rope 21;

[0038] In the process of using the glider-pulled unmanned aerial vehicle, the safety belt 91 is first worn on the staff or experimenter, the unmanned aerial vehicle tilts upward and flies, pulls the staff and experimenter to move, the glider generates upward lift under the action of the airflow, and the staff and experimenter are suspended in the air under the action of the resultant force of the lift of the glider and the lift of the unmanned aerial vehicle. The unmanned aerial vehicle continues to rise, the glider continues to rise under the action of the airflow, when it rises to a designated height, there is enough airflow in the air, the locking assembly 93 is separated from the carabiner 92, at this time the staff controls the glider to experience the joy of flying in the air with the experimenter;

[0039] In the process of flying, if an emergency occurs, the staff can separate the safety belt 91 from the locking assembly 93 by manually operating the carabiner 92, thereby improving the safety factor of flight;

[0040] In the process of being pulled by the unmanned aerial vehicle, the axial flow fan 5 can provide lateral wind force for the unmanned aerial vehicle, and the wing 3 provides vertical upward force for the unmanned aerial vehicle, so as to generate a tilted upward resultant force under the action of the lateral wind force and the vertical lift force. Under the action of the pulling of the unmanned aerial vehicle, the glider also generates a tilted upward pulling force, and the pulling force of the glider and the pulling force of the unmanned aerial vehicle generate a resultant force, so as to better pull the staff upward. Under the continuous pulling of the unmanned aerial vehicle, the glider, the staff and the experimenter continue to rise, so that take-off can be completed without relying on the condition of a barrier-free and windward slope, and the terrain restriction is completely eliminated: true flat take-off is realized, and the glider movement is expanded to vast plains, deserts, beaches, urban suburbs and other mountain-free areas, thereby expanding the accessibility of glider movement;

[0041] Enhanced take-off safety: provides stable and controllable acceleration and climbing process, eliminates common risks such as falling down when running on steep slopes, wing collapse, and loss of control caused by wind shear in traditional take-off.

[0042] Greatly reduce the dependence on weather: create take-off conditions through active pulling, significantly relax the harsh requirements on natural wind direction and wind speed, effectively extend the flyable days, and improve the site utilization rate;

[0043] Under the action of axial flow fan 5 unmanned aerial vehicle can produce enough tilt up traction force, traction staff, experience personnel move up;

[0044] When fly to the specified height can be separated after the connection can quickly separate the staff and traction rope 21, when ensuring that in the predetermined conditions or emergency can achieve timely, reliable separation, minimize the risk of separation accident.

[0045] "at the end of the release pipe 6 and unmanned aerial vehicle frame 1 installed with transmission 7, transmission 7 and wing 3 electric connection, transmission 7 for controlling the rotation speed of wing 3 control unmanned aerial vehicle lift" when the glider rises to the moving height, there is enough airflow in the high altitude can make the glider rise, at this time the release pipe 6 will be turned up, at this time under the action of transmission 7 makes the wing 3 has higher speed, makes the unmanned aerial vehicle move up, can make the glider, staff and experience personnel faster to reach the specified height.

[0046] Referring to Figure 1 , Figure 2 , Figure 3 , release pipe 6 includes inner tube 61, the outer tube 62 is set on the inner tube 61, the inner tube 61 and outer tube 62 sliding connection, the inner tube 61 is internally mounted with friction piece 63, the friction piece 63 is set on the traction rope 21, the traction rope 21 controls the release pipe 6 to lengthen and shorten; release pipe 6 is used for preventing the traction rope 21 from contacting with the wing 3; when the unmanned aerial vehicle takes off, the traction rope 21 is released, the inner tube 61 slides relative to the outer tube 62 under the action of the friction force of the friction piece 63 (rubber ring or ring structure fixed on the inner tube 61, the inner side is provided with brush) and the traction rope 21, so that the length of the release pipe 6 increases, when the release pipe 6 turns up, it can be extended to the side away from the fuselage of the wing 3, so that when the height of the unmanned aerial vehicle is lower than the height of the staff, the traction rope 21 can be prevented from contacting with the wing 3;

[0047] In special airflow weather conditions, the glider continues to rise, the unmanned aerial vehicle can be controlled to pull the glider, staff and experience personnel, fly obliquely downward, control the flight height of the glider, effectively prevent the glider from flying too high to bring danger to the staff and experience personnel, in this process, the unmanned aerial vehicle is located obliquely below the staff, the unmanned aerial vehicle, the staff and the glider are a diagonal line from top to bottom, because when the release pipe 6 is lengthened and turned to extend to the side away from the fuselage of the wing 3, the traction rope 21 can be prevented from contacting with the wing 3.

[0048] The paraglider rises to a certain height, and the connecting piece 9 separates the traction rope 21 from the staff, the traction rope 21 is retracted by the take-up and pay-off assembly 2, the inner tube 61 is retracted in the outer tube 62 under the action of friction, so that the pay-off tube 6 is shortened, and when the traction rope 21 is retracted, the pay-off tube 6 is completely shortened and the length is less than the height of the landing gear 4, so that the pay-off tube 6 can effectively prevent the unmanned aerial vehicle from landing.

[0049] With reference to Figure 2 and Figure 3 A limiting sliding ring 64 is installed at one end of the inner tube 61 close to the outer tube 62, a anti-off ring 65 is installed at one end of the outer tube 62 away from the unmanned aerial vehicle frame 1, a limiting spring 66 is sleeved on the inner tube 61, and the limiting spring 66 is located between the limiting sliding ring 64 and the anti-off ring 65, so that the inner tube 61 can be effectively prevented from being separated from the outer tube 62 under the action of the anti-off ring 65 and the limiting sliding ring 64; the limiting spring 66 is arranged between the limiting sliding ring 64 and the anti-off ring 65, so that the overlapping length of the inner tube 61 and the outer tube 62 can be increased, and the pay-off tube 6 can be effectively prevented from being broken or jammed.

[0050] With reference to Figure 1 and Figure 4 A limiting piece 8 is installed on the landing gear 4, and the limiting piece 8 is used to limit the overturning angle of the pay-off tube 6; the pay-off tube 6 can be effectively prevented from being overturned too much, so that the traction rope 21 contacts the wing 3 and affects the flight of the unmanned aerial vehicle.

[0051] The second lifting control embodiment:

[0052] With reference to Figure 1 and Figure 4 A swing traction motor 11 is installed on the unmanned aerial vehicle frame 1, the swing traction motor 11 is used to control the pay-off tube 6 to swing up and down in the limiting piece 8, and the limiting piece 8 controls the paraglider to rise;

[0053] When the unmanned aerial vehicle rises to a certain height, the pay-off tube 6 is controlled to swing up and down in the limiting piece 8 by the swing traction motor 11, the take-up and pay-off assembly 2 does not pay off when the pay-off tube 6 swings downward, and the take-up and pay-off assembly 2 pays off when the pay-off tube 6 swings upward, so that the paraglider can quickly rise to a specified height.

[0054] With reference to Figure 5, the landing gear 4 is provided with a control telescopic rod 41 for controlling the blowing direction of the axial flow fan 5; the telescopic end of the control telescopic rod 41 is rotatably installed on the axial flow fan 5, and the control telescopic rod 41 is rotatably installed on the landing gear 4; the axial flow fans 5 are fixed side by side, and the control telescopic rod 41 is installed on the upper and lower sides of the axial flow fan 5 in a symmetrical structure; one end of the control telescopic rod 41 away from the axial flow fan 5 is hinged to the landing gear 4, and the control telescopic rod 41 is used for controlling the up-down overturning of the axial flow fan 5; during the flight of the unmanned aerial vehicle, there are totally two groups of control telescopic rods 41, one group is installed on the upper side of the axial flow fan 5, and the other group is installed on the lower side of the axial flow fan 5; the control telescopic rod 41 on the upper side of the axial flow fan 5 is shortened, and the control telescopic rod 41 on the lower side of the axial flow fan 5 is lengthened, at this time, the axial flow fan 5 is overturned upward; the control telescopic rod 41 on the upper side of the axial flow fan 5 is lengthened, and the control telescopic rod 41 on the lower side of the axial flow fan 5 is shortened, at this time, the axial flow fan 5 is overturned downward; by controlling the lengthening and shortening of the control telescopic rod 41, the inclination angle of the axial flow fan 5 can be controlled, so that the resultant force between the thrust generated by the wind direction of the axial flow fan 5 and the lift of the wing 3 is generated, and the direction of the resultant force is close to the direction of the pay-off tube 6, so that the traction force can be better utilized; by controlling the inclination angle of the axial flow fan 5, the direction of the resultant force of the axial flow fan 5 and the wing 3 can be close to the direction of the pay-off tube 6, so that the balance of the unmanned aerial vehicle can be better maintained, and the flight of the unmanned aerial vehicle is more stable.

[0055] With reference to Figure 5 , the limiting piece 8 comprises a lower limiting rod 81 fixed transversely on the lower side of the landing gear 4, an upper limiting rod 82 fixed transversely on the landing gear 4, the lower limiting rod 81 and the upper limiting rod 82 are parallel to each other, and a pair of inclined limiting rods 83 are fixed on the lower limiting rod 81 and the upper limiting rod 82; the pay-off tube 6 is arranged between the inclined limiting rods 83; the lower limiting rod 81 limits the downward overturning angle of the pay-off tube 6, the upper limiting rod 82 limits the upward overturning angle of the pay-off tube 6, and the inclined limiting rod 83 is used for limiting the horizontal deflection of the pay-off tube 6; under the action of the lower limiting rod 81 and the upper limiting rod 82, the pay-off tube 6 is always inclined downward, so that the pay-off tube 6 can be effectively prevented from overturning excessively, and the traction rope 21 can be prevented from contacting the wing 3; after the pay-off tube 6 is lengthened, the pay-off tube 6 is contacted with the upper limiting rod 82 after being overturned upward, the pay-off tube 6 supports the traction rope 21, and the traction rope 21 can be further prevented from contacting the wing 3; at the same time, a protective cover is installed on the wing 3, which can effectively prevent the traction rope 21 from contacting the wing 3 and affecting the flight of the unmanned aerial vehicle.

[0056] With reference to Figure 1 , Figure 6The unmanned aerial vehicle frame 1 is provided with a control center 10, a gyroscope 12, and a camera 13 installed on the side of the unmanned aerial vehicle frame 1 close to the axial flow fan 5; the control center 10 comprises a storage module 101, a data processing module 102, and a radio module 103; the gyroscope 12, the transmission 7, the adjustable telescopic rod 41, the swing traction motor 11, the wing 3, and the axial flow fan 5 are electrically connected to the data processing module 102; two batteries are installed on the unmanned aerial vehicle frame 1, which supply power to the wing 3, the axial flow fan 5, and the control center; one of the two batteries is a working battery, and the other is a standby battery; when the unmanned aerial vehicle flies, the gyroscope 12 senses the change in the attitude of the unmanned aerial vehicle and transmits data to the data processing module 102; the data processing module 102 controls the wing 3 to rotate according to the data of the gyroscope 12, thereby maintaining the balance of the unmanned aerial vehicle.

[0057] When the unmanned aerial vehicle is towing a worker, an experience person, and a paraglider, the paraglider causes the angle of the pay-off pipe 6 to shift up and down during the ascending process; the pay-off pipe 6 is fixed on both sides of the end connected to the transmission 7, and the shaft is rotationally connected to the unmanned aerial vehicle frame 1; the pay-off pipe 6 drives the shaft to rotate during the overturning process; the shaft controls the transmission 7 to act; the transmission 7 transmits relevant data to the data processing module 102; the data processing module 102 controls the wing 3 to generate a vertical upward force; the data processing module 102 controls the adjustable telescopic rod 41 to adjust the angle of the axial flow fan 5, so that the resultant force of the wing 3 and the axial flow fan 5 is the same as the direction of the traction force on the pay-off pipe 6, thereby maximizing the traction force and facilitating the balance of the unmanned aerial vehicle.

[0058] In order to make the paraglider reach the specified height faster, the swing traction motor 11 drives the angle of the pay-off pipe 6 to swing up and down, and the data processing module 102 controls the pay-off and take-up assembly 2 to pay off the line; the pay-off pipe 6 stops paying off the line during the downward swinging process, and pays off the line during the upward swinging process, thereby making the paraglider reach the specified height faster; (in this process, the transmission 7 stops working).

[0059] When the paraglider reaches the specified height, the data processing module 102 controls the separable connecting piece 9 to act through the radio module 103 (WiFi signal or electromagnetic wave signal) to separate the traction rope 21 from the worker, or sends a separation instruction through the remote controller, transmits the instruction to the data processing module 102 through the radio, and controls the separable connecting piece 9 to act through the radio module 103.
