[0042] In a further embodiment of the present invention: The motor shaft drive assembly includes a motor 321 , a shaft 322 and a right-angle reducer 323 .

[0043] The rotating shaft 322 is connected to the right-angle reducer 323; the motor 321 drives the right-angle reducer 323 to rotate through the coupling.

[0044] The ball screw drive assembly includes a ball screw 331 and a slider 332 .

[0045] The right-angle reducer 323 is connected to the ball screw 331 through a coupling; the slider 332 can move along the X-axis and the Y-axis, and the slider 332 is connected to a moving part 334. A slide groove 333 for the moving part to move along the X-axis and the Y-axis is provided at the end close to the panel assembly 312, and the moving part 334 protrudes from the surface of the panel assembly 312 to push the drone to move along the X-axis and the Y-axis.

[0046] It should be noted that the panel assembly 312 includes a large panel and a small panel that are interlocked with each other, and the small panel is interlocked in the center of the large panel. The slide grooves 333 are symmetrically arranged on the surface of the large panel; and a through hole is opened in the center of the small panel for the drone cable to pass through.

[0047] When in use, power is supplied to the motor 321, and the coupling connected to the motor shaft drives the rotating shaft 322 fixed to the right-angle reducer 323, and then the right-angle reducer 323 drives the ball screw 331 fixed to it through the coupling, so that the slider 332 matched with the ball screw 331 drives the moving part 334 fixed to it to push the drone, thereby realizing the free movement of the drone on the X and Y axes, and being able to more conveniently adjust the take-off position of the drone.

[0048] About winch cable retracting mechanism 400: See also Figure 4 The UAV cable can pass through the UAV retractable platform 300 and be connected to the winch cable retractable mechanism 400. The winch cable retractable mechanism 400 includes a winding wheel assembly, a cable arrangement assembly and an electrical control assembly. The electrical control assembly drives the winding wheel assembly to rotate, and under the continuous drive of the cable arrangement assembly, the UAV cable can be neatly arranged on the winding wheel assembly.

[0049] In a further embodiment of the present invention, the winch cable retracting and releasing mechanism 400 includes an aluminum profile frame, which is located in the accommodating space of the base 100, and the winding wheel assembly, the cable arrangement assembly and the electrical control assembly are arranged on the aluminum profile frame.

[0050] The winding wheel assembly comprises a winding wheel 411, a reciprocating screw rod 412, a sprocket wheel 413 and a chain. One end of the reciprocating screw rod 412 is connected to the winding wheel 411 through a chain, and the sprocket wheel 413 and the chain transmit power to the reciprocating screw rod 412 to drive the winding wheel 411 to rotate.

[0051] The cable arrangement assembly includes a cable arranger 421. The cable arranger 421 is connected to the end of the reciprocating screw rod 412. The cable arranger 421 guides the direction of the drone cable and maintains the tension of the drone cable under the rotation of the reciprocating screw rod 412. Ensure that the drone cables are neatly arranged on the winding wheel 411 in a predetermined order and spacing during the retraction and release process to avoid cable knotting or improper winding. At the same time, every time the winding wheel 411 rotates one circle, the drone cable will be horizontally displaced a fixed distance in the specified direction under the drive of the reciprocating screw rod 412. This design helps to evenly distribute the cables and prevent overlap and confusion. In addition, when the drone cable reaches the two side plates of the winding wheel 411, the reciprocating screw rod 412 immediately runs in the opposite direction to achieve automatic direction change.

[0052] The electrical control components include PLC431, servo 432 and servo motor 433 equipped with encoder. PLC431 is responsible for control programming to realize automatic control of the entire winch. Servo 432 receives signals from PLC431 to adjust the speed and direction of servo motor 433.
