[0029] Please refer to Figures 1 - 7 , an embodiment of the present invention provides a paraglider towing device suitable for the development of regional tourism, including a fuselage 1 and a control device 7. A servo drive device 2, a winch 3, and a wire guiding device 4 are installed inside the fuselage 1. The servo drive device 2 is connected to the winch 3 through a transmission device 5. The winch 3 is connected to the wire guiding device 4 through a speed change device 6. The wire guiding device 4 includes a reciprocating shaft 43 fixedly installed inside the fuselage through a bearing 42. A wire guide 41 is movably installed on the reciprocating shaft. One end of a towing rope is fixed on the winch 3 and then reciprocally wound from one end of the winch to the other end. The indexing end of the towing rope on the winch 3 passes through the wire guide 41. The running direction of the wire guide 41 is the same as the winding direction of the indexing rope. When the present application is specifically implemented, the towing rope passes through the wire guide and is fixed to the hook of the pilot. When the drive device is started, the control device calculates the real-time tension and real-time length according to the load information to adapt to the flying speed of the paraglider. While the transmission device drives the winch to rotate, the speed change device drives the wire guide of the wire guiding device to move synchronously with the towing rope, which can ensure the smooth winding of the towing rope. Specifically, the servo drive device 2 includes a servo motor and a servo driver. The drive end of the servo motor is connected to the transmission device and is used to drive the winch to operate.

[0030] Specifically, the reciprocating shaft is a left-right reciprocating rotating shaft. Two thread grooves with the same pitch and opposite helix directions are provided on the surface of the rotating shaft, which converts the rotational motion of the servo motor, the transmission device, and the speed change device into a linear left-right reciprocating motion. It plays an important role in the structure of the present application, can achieve precise linear motion control, and has a simple structure and reasonable design.

[0031] The transmission device 5 drives a driving pulley 51 and a driven transmission pulley 52. The driving pulley 51 is fixedly installed on the drive shaft of the servo drive device 2. The driven transmission pulley 52 is fixedly installed on the rotating shaft of the winch 3. The driving pulley 51 and the driven transmission pulley 52 are connected by a synchronous belt.

[0032] Specifically, it further includes a tensioning device 10. The tensioning device 10 includes a rotating plate. One end of the rotating plate is fixedly connected to the rotating end of the tensioning rotation driving device, and the other end is equipped with a tensioning wheel for adjusting the tension of the synchronous belt.

[0033] The wire guiding device 4 includes a reciprocating shaft 43 fixedly installed in the fuselage through a bearing 42. The wire guide 41 includes a wire frame 411 that is installed in a matching manner on the reciprocating shaft 43 and reciprocates thereon. At least a pair of wire rollers 412 are installed on the wire frame 411, and a gap for the traction rope to pass through is left between the pair of wire rollers 412.

[0034] Specifically, two pairs of wire rollers are installed on the wire frame 411, and the two pairs of wire rollers are arranged perpendicular to each other. The relative gap between the two pairs of wire rollers in this application is located at the center of the wire guide, ensuring the stability of the direction when the traction rope is paying out and taking in.

[0035] The speed change device 6 includes a speed change driving wheel 61 fixedly installed on the rotating shaft of the winch 3, a speed change driven wheel 62 fixedly installed on the reciprocating shaft 43, and multiple sets of speed change wheel sets 63. The speed change driving wheel 61, the multiple sets of speed change wheel sets 63, and the speed change driven wheel 62 are connected by a transmission belt.

[0036] Specifically, two sets of speed change wheel sets are provided. The first speed change wheel set includes a first large speed change wheel 633 and a first small speed change wheel 634, and the second speed change wheel set includes a second large speed change wheel 631 and a second small speed change wheel 632. More specifically, the connection relationship is that the first large speed change wheel is connected to the second small speed change wheel by a transmission belt, and the second small speed change wheel and the first large speed change wheel are connected by a transmission belt.

[0037] A heat dissipation device 8 is also installed in the fuselage. The heat dissipation device 8 is located above the servo drive device 2.

[0038] The control device 7 includes a control panel 71 and a control handle 72. The control panel 71 is installed at the upper end of the fuselage 1. A plurality of potentiometers and a plurality of displays are installed on the control panel 71. At least one potentiometer and at least two switches are provided on the control handle 72. More specifically, the control handle includes a handle body, an accelerator push rod, a tight rope auxiliary switch, and a rope release auxiliary switch.

[0039] At least one sensor 9 is provided on the fuselage 1 corresponding to one end of the winch 3 for detecting the number of rotations of the winch.

[0040] The control device further includes an information processing component for automatically adjusting the traction speed according to the load information to adapt to the flight speed of the paraglider.

[0041] A paraglider winch take-off system includes the take-off device and control device described in any of the above. During take-off, the information processing component automatically adjusts the winch speed according to the load information through the system algorithm to match the paraglider flight speed, detects the number of rotations of the winch through a sensor, calculates the current diameter of the winch, calculates the deviation between the actual tension of the final tow rope and the throttle calibration value based on the winch diameter, and finally performs real-time correction in the control device.

[0042] The winch has 6 parameter displays, specifically including:

[0043] Among them, 'Real-time length' represents the length of the rope pulled out currently, with the unit of circle, and a proximity sensor is used to read the parameter. The length can be reset using a knob, but it cannot be set;

[0044] Among them, 'Take-off weight' represents the total mass of the pilot during take-off (including the person and equipment), with a maximum setting of 250 kg. The function of this parameter is to set the maximum given range of the throttle. For example, when the pilot's take-off weight is 120 kg, set this parameter to 120. Then, when the throttle is pushed to the full, the maximum tension of the tow rope is 120 kg. The parameter adjustment method is to rotate the potentiometer.

[0045] Among them, 'Real-time tension' represents the given value of the current throttle (the amount of throttle pushed). For example, when the operator sets the 'Take-off weight' to 200 and pushes the throttle halfway, it will be displayed as 100 here, which is only a feedback of the throttle amount given by the operator, and the display unit is kg.

[0046] Among them, 'Tension compensation' is used to balance the influence of the change in the winch diameter on the tension during the winching process and compensate for the wind resistance generated by the tow rope itself. The setting range is 0 - 100. When the winch diameter is 160 mm, when all 1600 m of 5 mm tow rope is wound onto the winch, the winch needs to rotate approximately 2250 circles, and at this time, the maximum winch diameter (about 320 mm) is reached. When the magnetic sensor detects the line being pulled out and records the value, it is possible to know how many turns the tow rope has been pulled out. Since the winch diameter is half as small when all the tow rope is on the winch compared to when all the tow rope is pulled out, and the force arm is half as small, it means that the tension on the rope will also be halved. Therefore, the set parameter and the detected number of turns need to be imported into the following formula, and the percentage of the final motor output torque to the motor rated torque is obtained through real-time calculation and converted into an analog signal to be sent to the servo system for processing. Hereinafter referred to as the motor given torque:

[0047] Motor given torque = [(1 - tension compensation ÷ 100) × (1 - real-time length ÷ 2250) + tension compensation ÷ 100] × (take-off weight ÷ 250)

[0048] At this time, the tension compensation setting of 50 can match this system because the minimum winch is 160mm and the maximum winch is 320, and exactly the minimum diameter is 50% of the maximum diameter. However, since it is possible for the customer to replace the non-original line during use, we design this parameter to be adjustable. The user can set this parameter according to the ratio of the minimum diameter ÷ the maximum diameter to ensure that the tension is not affected as much as possible. At the same time, because during the traction takeoff process, after the traction rope is pulled out, the air resistance generated by the traction rope itself is proportional to the 'actual length', so the operator can appropriately increase the 'tension compensation' from the basis of 50 to compensate for the lost tension. The parameter adjustment method is potentiometer rotation adjustment;

[0049] Among them, 'tightening rope assistance' means that after the tightening rope assistance function is turned on, the traction machine will always maintain the tension set by this parameter. The setting range of this parameter is (0 - takeoff weight), but it is usually set relatively small, only to ensure that the traction rope is not loose during the traction process, to ensure the synchronization of the glider speed and the traction machine rotation speed, and to avoid the additional risk caused by the sudden tightening of the traction rope when the throttle is closed halfway and then the throttle is applied again after the traction rope becomes loose. After turning on the tightening rope assistance, it does not affect the use of the throttle push rod. The parameter adjustment method is potentiometer rotation adjustment, and this tightening rope assistance switch is integrated on the throttle handle. Press to turn on, press again to turn off;

[0050] Among them, 'rope releasing assistance' means that after the rope releasing assistance function is turned on, the traction machine will always maintain the tension set by this parameter. The setting range is -100 - 0. Since the tension it provides is reverse, its parameter is negative, and the maximum can be set to 0. Its function is to reduce the resistance when pulling out the traction rope outward by reverse rotation during the reciprocating traction of the glider. Thus, it reduces the influence of the mechanical resistance of the traction machine on the reciprocating traction efficiency. When using this function, the throttle push rod and the system assistance are invalid. The parameter adjustment method is potentiometer rotation adjustment. The rope releasing assistance switch is integrated on the control handle. Press to turn on, lift the hand to turn off. The control handle consists of the handle body, the throttle push rod, the tightening rope assistance switch, and the rope releasing assistance switch, and is connected to the traction machine operating system through a 2m spring wire.

[0051] A method for glider traction takeoff, comprising the following steps:

[0052] 1S1. The traction rope is fixed to the pilot's hook, and the driving device of the traction machine starts to wind up the traction rope to provide the pilot with forward pulling force;

[0053] S2. During the takeoff process, adjust the traction speed to adapt to the glider flight speed;

[0054] S3. During the process of taking in the line, the glider pilot will also fly higher and higher. When the maximum unhooking angle is finally reached, the pilot separates the traction rope and performs free gliding.

[0055] More specifically, the traction speed can be adjusted by controlling the potentiometer on the control panel, or by controlling the potentiometer or switch on the control handle, and can be selected according to the actual flight situation of the pilot.

[0056] The information processing component of the present application stores parameter information, calculates the real-time pulling force and real-time length of the flight crew according to the stored parameter information to adapt to the paraglider flight speed, is applicable to a variety of flight crew, can improve the takeoff efficiency, and the takeoff system integrates and optimizes resources such as manpower, site, and power, which conforms to the resource allocation theory in "economic management". At the same time, the takeoff system is standardized, the user threshold is reduced, and it has the advantages of expanding the service scale, etc., and is suitable for the development of regional tourism.
