The frame includes an upper base plate and a lower base plate fixedly connected to the upper base plate. A driving rod is fixedly arranged on the mounting plate, and the driving rod is spline-connected to the guide cylinder. An electromagnetic block 1 is arranged on the top of the guide cylinder, and an electromagnetic block 2 adapted to the electromagnetic block 1 is arranged in the driving rod. The drone realizes stable traction of the cable by controlling the expansion range of the movable cantilever 1 and the movable cantilever 2. However, the drone still has the following problems: 1.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0029] Embodiment 1: In some embodiments, please refer to the drawings of the specification Figure 1-Figure 7 , a UAV for cable construction, comprising a UAV body 1; The lower end of the drone body 1 is provided with a wire-hanging mechanism 4, which includes a wire-winding assembly 41, a wire-fixing assembly 42 and a sway-eliminating assembly 43.

The adjustable planetary rotating mechanism 3 drives the communication antenna 2 to continuously rotate and revolve to search for signal sources in a wide range; A resistance-wire folding support structure 5 is provided at the lower end of the drone body 1 , and the resistance-wire folding support structure 5 is used to support the drone body 1 on the ground and prevent the cable from being pulled by wind and colliding with the rotor of the drone body 1 .

[0030] In the present invention, the drone body 1 stands on the ground through the line-blocking folding support structure 5. The operator fixes the end of the cable to be towed on the winding assembly 41 through the wire fixing assembly 42, and then starts the winding assembly 41 to reel in the wire. After the wire arrangement is completed, the operator controls the drone body 1 to fly to the set position. When the drone body 1 is started or stopped, the winding assembly 41 is controlled to swing with the swing of the towed cable through the anti-sway assembly 43, so as to assist the drone in quickly eliminating the swing of the cable, so that the drone body 1 can be kept stable in a short time, reducing the risk of the drone body 1 losing control due to uneven distribution of the center of gravity, effectively increasing the controllability of the drone body 1, and improving the efficiency of cable construction. After the drone body 1 hovers at the set position, the cable winding assembly 41 slowly unwinds the cable to cooperate with the cable installation operation. After the cable is completely released, the locking effect of the cable end is released by the cable fixing assembly 42, thereby smoothly releasing the cable. During the flight of the drone body 1, the adjustable planetary rotating mechanism 3 drives the communication antenna 2 to continuously rotate and revolve, and the communication antenna 2 can always search for signal sources in a large range, thereby effectively improving the signal stability of the drone body 1 when the drone body 1 works in remote areas.

The lower end of the claw 425 is hinged to the right end of the winding roller 416, and the annular slider 424 is connected to the roller shaft 414 through a key, so that the annular slider 424 rotates synchronously with the roller shaft 414 and the annular slider 424 can move axially along the roller shaft 414; the lower end of the claw 425 is hinged to the right end of the winding roller 416, and the two ends of the connecting rod 426 are respectively hinged to the claw 425 and the annular slider 424; The push block 422 is rotatably connected to the annular slider 424 through a bearing, the first electric push rod 421 is fixedly connected to the side support plate 412, and the output end of the first electric push rod 421 is fixedly connected to the push block 422; one end of the guide slide 423 is fixedly connected to the push block 422, and the other end of the annular slider 424 is limitedly slidably connected to the side support plate 412; The anti-sway assembly 43 includes a second electric push rod 431 and a cross bar 432, the cross bar 432 is fixedly installed between the side support plates 412, the shell of the second electric push rod 431 is hinged to the drone body 1 through a connecting piece, and the output end of the second electric push rod 431 is hinged to the cross bar 432 through a connecting piece; In the present invention, the first electric push rod 421 can drive the push block 422 to slide axially along the winding roller 416 under the limiting action of the guide slide rod 423, and push the annular slider 424 in the direction of the winding roller 416. The annular slider 424 closes the claw 425 through the connecting rod 426, and the end of the cable is locked on the winding roller 416. Then, the servo motor 415 drives the winding roller 416 to rotate to perform the cable winding operation. When the drone body 1 starts or stops, the cable swings greatly due to the drastic change in acceleration. At this time, the second electric push rod 431 pushes the bracket 411 through the cross bar 432 to control the winding roller 416 to swing around the rotating shaft 413, so that the winding roller 416 and the cable swing synchronously, thereby achieving rapid swing elimination.

The two communication antennas 2 cooperate to maintain a good communication effect between the drone body 1 and the operator. By pulling out the pull rod 395 to separate the fixed gear block 393 and the adjusting gear block 394, the inclination angle of the adjusting platform 38 can be adjusted to meet the communication requirements of the drone body 1 under different working conditions, effectively increasing the scope of application of the present application.
