Description

Technical Field

[0001] This utility model relates to the field of aviation sports equipment technology, and in particular to a novel paraglider towing device. Background Technology

[0002] A paraglider towing mechanism consists of a tow line, pulleys, a tow rope, and a towing machine. The towing machine is a device that uses the pulling force generated by an engine or motor to slowly tighten the tow rope, giving the paraglider lift and allowing it to ascend into the air. A towing machine typically consists of an engine, transmission, shaft, and winding mechanism. The working principle of the paraglider towing mechanism is as follows: before takeoff, the paraglider is connected to the towing machine using the tow line, which is passed through the pulley and then wound onto the towing machine's winding mechanism. When the towing machine starts, the pulling force generated by the engine or motor slowly tightens the tow rope, gliding until lift is achieved, causing the paraglider to rise and begin flight. A paraglider towing mechanism is an important tool for enabling rapid parachute movement or personnel parachuting. It consists of a paraglider, tow line, tow rope, pulleys, and a towing machine, and ascends the paraglider into the air by retracting the tow rope. Before use, safety precautions should be taken to ensure that all parts are functioning properly to avoid unnecessary injury.

[0003] However, some traditional towing machines may have insufficient dry and wet separation design in their motor structure, posing a risk of water ingress and short circuits in humid environments such as at sea or on lakes. Furthermore, because the towing rope is greatly affected by wind forces during the towing process, tension fluctuations can occur, affecting the paraglider's stable ascent. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of insufficient dry and wet separation design in the motor structure of some existing traction mechanisms, which may pose a risk of water ingress and short circuits at sea or on lakes. Furthermore, because the traction mechanism is greatly affected by wind force during the traction process, the tension of the traction rope is prone to fluctuations, affecting the stable ascent of the paraglider. Therefore, this invention provides a novel paraglider traction device.

[0005] The purpose of this utility model is achieved through the following technical solution: a novel paraglider traction device, including an outer shell, in which a rotatable electric drum is installed. The electric drum adopts a tile-type hub direct drive system, which integrates a permanent magnet motor with the drum. The magnetic field distribution is optimized by using a specially designed "tile-type" permanent magnet layout, eliminating traditional mechanical components such as gearboxes, drive shafts, and differentials, effectively reducing transmission losses. Furthermore, the direct drive structure can effectively eliminate gear meshing noise and improve the smoothness of operation.

[0006] The electric drum is used to wind up the traction rope. A lead screw corresponding to the electric drum is installed inside the outer shell. A lead screw nut is installed on the lead screw. A slide rod corresponding to the lead screw nut is installed inside the outer shell. One end of the lead screw nut is slidably connected to the slide rod. A traction rope guiding mechanism corresponding to the electric drum is installed between the lead screw nut and the slide rod.

[0007] By replacing the traditional motor with an electric roller, the device offers excellent sealing performance, protecting the electrical components inside the roller and effectively preventing dust and water damage. This avoids the risk of water ingress and short circuits in humid environments such as at sea or on lakes, ensuring the stability of the electric roller's operation and improving equipment safety.

[0008] The main shaft inside the electric drum is connected to one end of the lead screw via a reducer. A power input socket corresponding to the electric drum is installed on one side of the outer casing. Waterproof shells are installed on the outside of both the reducer and the power input socket. By setting the main shaft inside the electric drum to be connected to one end of the lead screw via a reducer, the lead screw can be driven, causing the lead screw nut on the lead screw to move and lay the cable. The waterproof shells installed on the outside of both the reducer and the power input socket further improve the waterproof performance of the equipment and effectively extend the service life of the equipment in humid environments.

[0009] A further technical solution involves installing a tension sensor on the electric drum. This sensor detects the tension of the traction rope and is connected to a control module that controls the rotational speed of the electric drum. During the traction process, the tension sensor monitors the tension of the traction rope in real time. When the tension of the traction rope falls below a preset range, the tension sensor sends a signal to the control module that controls the rotational speed of the electric drum. The control module then controls the electric drum to increase its rotational speed, allowing the traction force of the electric drum to quickly return to the preset range. This achieves dynamic compensation of the traction force of the paraglider, ensuring the stability of the traction force of the electric drum, and thus enabling the paraglider to take off smoothly.

[0010] A further technical solution is that the traction rope guiding mechanism includes a horizontal guide roller, two rotatable vertical guide rollers are installed in the middle of the horizontal guide roller, and two sets of rotatable rollers are installed on both sides of the two vertical guide rollers. By setting the vertical guide rollers on the horizontal guide roller to cooperate with each other, the electric drum can be made to wind the traction rope more smoothly, so that the traction rope is evenly, neatly and tightly wound on the electric drum during the winding process.

[0011] A further technical solution is to install limit plates on both sides of the electric drum. By setting the limit plates, the traction rope wound on the electric drum can be limited, preventing the traction rope from falling off from both sides of the electric drum.

[0012] A further technical solution is to install mounting ears on the bottom of the housing. By setting mounting ears, the installation and disassembly of the housing can be facilitated, thereby improving the efficiency of the housing assembly and disassembly.

[0013] A further technical solution is to install a transparent observation plate on the top of the outer casing, corresponding to the electric drum. By setting up a transparent observation plate on the outer casing corresponding to the electric drum, it is convenient for staff to observe the winding of the traction rope by the electric drum and the operating status of the equipment inside the outer casing, so as to facilitate the timely detection of faults.

[0014] A further technical solution involves an electric drum connected to a controller via a power input socket. The controller is equipped with a display screen and communicates with external devices via a signal receiver. It also includes adjustment and emergency braking buttons for controlling the electric drum. The display screen shows the real-time speed and torque of the electric drum for easy monitoring. The controller connects to the electric drum's power input socket via three-phase lines and Hall effect sensors, enabling smoother, more efficient, and higher-powered three-phase system operation with greater and more constant torque. By transmitting the rotor position sequence via the Hall effect sensors, the controller can determine the current direction of rotation. To reverse the direction, simply adjust the energizing sequence of the stator windings, such as by swapping the logic of two Hall effect sensors, to change the motor's rotation direction.

[0015] This invention has the following advantages: By replacing the traditional motor with an electric roller, it has excellent sealing performance, protecting the electrical components inside the electric roller and effectively preventing dust and water damage. This avoids the risk of short circuits due to water ingress in humid environments such as at sea or on lakes, ensuring the stability of the electric roller's operation and improving the safety of the equipment. A tension sensor monitors the tension of the traction rope in real time. When the tension of the traction rope falls below a preset range, the tension sensor sends a signal to the control module that controls the speed of the electric roller. The control module then controls the electric roller to increase its speed, allowing the traction force of the electric roller to quickly return to the preset range. This achieves dynamic compensation of the paraglider's traction force, ensuring the stability of the electric roller's traction force and enabling the paraglider to take off smoothly.

[0027] like Figures 1-3 As shown, a novel paraglider traction device includes an outer shell 1, inside which a rotatable electric drum 2 is installed. The electric drum 2 is used to wind up the traction rope. The electric drum 2 uses a tile-type hub direct drive system, which integrates a permanent magnet motor with the drum. The specially designed "tile-type" permanent magnet layout optimizes the magnetic field distribution, eliminating traditional mechanical components such as gearboxes, drive shafts, and differentials, effectively reducing transmission losses. Furthermore, the direct drive structure can effectively eliminate gear meshing noise and improve the smoothness of operation.

[0028] Inside the outer casing 1, there is a lead screw 3 corresponding to the electric drum 2. A lead screw nut 4 is installed on the lead screw 3. Inside the outer casing 1, there is a slide rod 5 corresponding to the lead screw nut 4. One end of the lead screw nut 4 is slidably connected to the slide rod 5. A traction rope guiding mechanism 6 corresponding to the electric drum 2 is installed between the lead screw nut 4 and the slide rod 5.

[0029] By replacing the traditional motor with an electric roller 2, the device has excellent sealing performance, which can protect the electrical components inside the electric roller 2. This effectively prevents dust and water damage, avoids the risk of water ingress and short circuits in humid environments such as at sea or on lakes, ensures the stability of the electric roller 2's operation, and improves the safety of the equipment.

[0030] The main shaft inside the electric drum 2 is connected to one end of the lead screw 3 via a reducer 7. A power input socket 8 corresponding to the electric drum 2 is installed on one side of the outer casing 1. Waterproof shells are installed on the outside of both the reducer 7 and the power input socket 8. By setting the main shaft inside the electric drum 2 to be connected to one end of the lead screw 3 via the reducer 7, the lead screw 3 can be driven, causing the lead screw nut 4 on the lead screw 3 to move and lay the cable. The waterproof shells installed on the outside of both the reducer 7 and the power input socket 8 further improve the waterproof performance of the equipment and effectively extend the service life of the equipment in humid environments.

[0031] A tension sensor is installed on the electric drum 2. The tension sensor is used to detect the tension of the traction rope. The tension sensor is connected to the control module that controls the rotation speed of the electric drum 2. During the traction process, the tension sensor monitors the tension of the traction rope in real time. When the tension of the traction rope is lower than the preset range, the tension sensor sends a signal to the control module that controls the rotation speed of the electric drum 2. The control module controls the electric drum 2 to increase its rotation speed so that the traction force of the electric drum 2 can be restored to the preset value range as soon as possible. This achieves dynamic compensation of the traction force of the paraglider, ensures the stability of the traction force of the electric drum 2, and thus enables the paraglider to take off smoothly.

[0032] The traction rope guiding mechanism 6 includes a horizontal guide roller 601, with two rotatable vertical guide rollers 602 installed in the middle of the horizontal guide roller 601. Two sets of rotatable 603 are installed on both sides of the two vertical guide rollers 602. By setting the vertical guide rollers 602 and 603 on the horizontal guide roller 601 to cooperate, the electric drum 2 can be made to wind the traction rope more smoothly, so that the traction rope is evenly, neatly and tightly wound on the electric drum 2 during the winding process.

[0033] Limiting plates 10 are installed on both sides of the electric roller 2. By setting the limiting plates 10, the winding traction rope on the electric roller 2 can be limited to prevent the traction rope from falling off from both sides of the electric roller 2.

[0034] The bottom of the outer casing 1 is equipped with mounting ears 9. By setting the mounting ears 9, the installation and disassembly of the outer casing 1 can be facilitated, thereby improving the efficiency of the installation and disassembly of the outer casing 1.

[0035] The top of the outer casing 1 is equipped with a transparent observation plate corresponding to the electric drum 2. By setting the transparent observation plate on the outer casing 1 corresponding to the electric drum 2, it is convenient for the staff to observe the winding of the traction rope by the electric drum 2 and the operating status of the equipment inside the outer casing 1, so as to facilitate the timely detection of faults.

[0036] The electric drum 2 is connected to a controller 11 via a power input socket 8. The controller 11 is equipped with a display screen 12 and communicates with external devices via a signal receiver 13. The controller 11 is equipped with adjustment keys 14 and an emergency brake key 15 for controlling the electric drum 2. The display screen 12 is used to display the real-time speed and torque of the electric drum 2 for easy observation by the operator. The controller 11 is connected to the power input socket 8 of the electric drum 2 via three-phase lines and Hall effect lines, which enables the three-phase system to operate more smoothly, with higher efficiency, better power factor, and greater and more constant torque. The controller can determine the current direction of rotation by transmitting the rotor position sequence through the Hall effect lines. When reversal is required, the energizing sequence of the stator windings can be adjusted, such as by swapping the logic of two Hall effect signals, to change the direction of motor rotation.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
