Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a ground-based cable supply device for troubleshooting radio interference from UAVs. Background Technology
[0002] Troubleshooting radio interference in unmanned aerial vehicles (UAVs) is a critical technical task aimed at identifying, locating, and resolving sources of radio interference that affect the normal communication and navigation of UAVs. This is of great significance for ensuring the safe and stable operation of UAVs in complex environments.
[0003] However, traditional devices lack a buffer mechanism. When the cable is accidentally straightened or suddenly pulled, it is prone to severe impact, increasing the risk of cable damage. This instantaneous pulling can easily cause the cable to bend, be damaged, or loosen, affecting the continuity of normal use and testing.
[0004] Therefore, those skilled in the art have provided a ground-based cable rope device for troubleshooting radio interference from unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a ground-based cable supply device for troubleshooting radio interference from unmanned aerial vehicles (UAVs). This device is equipped with a buffer mechanism. When the cable is accidentally straightened, the second roller applies pressure to the return spring, thus buffering and absorbing the force exerted on the cable during tautness. The spring-returning roller automatically returns to its original position when the tension reaches a preset value, reducing sudden pulling and mechanical impact on the cable, protecting it from damage, and extending its service life. Furthermore, the user can adjust the pressure of the return spring by adjusting the locking nut, allowing the user to flexibly set the required straightening force according to the actual usage scenario or factors such as the cable's weight and stiffness, thereby improving the device's applicability and ease of use.
[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0014] Furthermore, the servo motor is fixedly connected to the front end inside the battery holder, and the output end of the servo motor is fixedly connected to the outer wall of the front end of the fixed shaft.
[0015] The above technical solution enables the servo motor to generate power to the fixed axis.
[0016] Furthermore, the guide rods are respectively fixedly connected to one side of the upper end of the inner wall of the placement frame, and guide grooves are provided around the outer wall of the front end of the movable seat. The guide rods are slidably connected to the guide grooves.
[0017] The above technical solution enables the movable seat to slide smoothly on the guide rod.
[0018] Furthermore, the drive sprocket is fixedly connected to the rear end of the outer wall of the fixed shaft, and the end of the chain away from the drive sprocket meshes with the auxiliary sprocket;

[0020] Furthermore, the reciprocating lead screw is rotatably connected to one side of the upper end of the inner wall of the placement frame;
[0021] The above technical solution enables the reciprocating lead screw to control the movement of the moving seat on the placement frame.
[0022] Furthermore, a control panel is fixedly connected to the front end of the upper surface of the battery storage base;

[0043] Working principle: First, connect the drone to be tested to cable 2012 and turn off the self-locking mode of servo motor 2010. When the drone rises, it pulls cable 2012, causing the take-up roller 2011 to rotate. This, combined with the meshing transmission of sprocket and chain 303, causes the reciprocating screw 304 to rotate synchronously with the take-up roller 2011, thus completing the cable unwinding operation. When the drone reaches the preset height, the self-locking mode of servo motor 2010 is activated. If the drone is accidentally straightened, the second roller 3012 moves along with the rectangular slide bar 3010, thereby squeezing the return spring 3013 to generate pressure on cable 2012. The tension on cable 2012 is buffered and absorbed. As the return spring 3013 resets, the cable 2012 is reset. The user can adjust the pressure of the return spring 3013 by turning the locking nut 3015. The adjustment force can be adjusted more precisely by pressing the threaded rod 3014 through the sensor. As the take-up roller 2011 rotates, the gear 208 rotates and moves the lever 204. Each move adjusts the value of the mechanical counter 203 to detect the length of the cable 2012. The slip ring module 202 can transmit current to the UAV through the cable 2012 via electrical connection with the conductive post 209.
