Technical Field

[0002] A drone is an aircraft with a power system, a flight control system, and a communication system. The flight control system allows the drone to maintain a stable posture in the air and fly according to a preset route. The communication system is responsible for receiving and sending signals so that the operator can remotely control the drone from the ground. An anti-electromagnetic interference drone is a drone that can resist electromagnetic interference. The following methods are usually used to achieve anti-electromagnetic interference: electromagnetic shielding, using metal shielding materials or electromagnetic protection nets to wrap the key components of the drone, optimizing antenna design, and adopting a reasonable antenna design and layout, such as directional antennas, using a multi-source navigation system, and using fiber optic control. Drones that use fiber optic control usually have to hang a fiber optic tube of a similar size to the size of the drone. Current fiber optic tubes are usually cylindrical, have a large flight resistance, and are disposable items that cannot be quickly replaced. At the same time, the optical fiber cannot be recycled. Because the hanging fiber optic tube is large, the drone usually requires a specific platform support or a longer tripod to support the drone to take off normally.

The windshield 32 reduces the wind resistance of the UAV body 1 during flight. The retracting frame 33 limits the space when the optical fiber is released, so that the optical fiber maintains a stable release state when released. The containing frame 31 is flat, which reduces the height of the UAV body 1 without reducing the containing body size, which is beneficial to improving the passability of the UAV in a narrow ring.

[0032] The optical fiber release device 3 also includes: a fixed rod 310, a sliding frame 311 and a connecting plate 312, the fixed rod 310 is fixedly installed on the middle side of the wind shield 32, the sliding frame 311 is slidably connected to the fixed rod 310, and the connecting plate 312 is fixedly installed on the left side of the sliding frame 311.

[0034] The rapid deployment device 2 includes: a special-shaped shell 21, a limiting rod 22, a sliding column 23 and a second tension spring 24.

[0035] The sliding column 23 of the rapid deployment device 2 moves upward smoothly under the restriction of the restriction rod 22, and at this time the second tension spring 24 is elastically deformed and stretched, and the second tension spring 24 is used to provide tension for the sliding column 23 to return to its initial state.

[0036] The rapid deployment device 2 also includes: a gear 25, a support rod 26 and a foot pad 27. The four gears 25 are arranged in a circular array in the special-shaped shell 21 with the central axis of the special-shaped shell 21 as the center. The gear 25 is rotatably connected in the special-shaped shell 21 through a rotating shaft. The support rod 26 is fixedly installed on the side wall of the gear 25. The foot pad 27 is fixedly installed on the end of the support rod 26 away from the gear 25. The gear 25 and the multiple teeth on the side wall of the sliding column 23 are meshed with each other.

[0037] The sliding column 23 moves upward steadily to drive the gear 25 to rotate, and the rotation of the gear 25 drives the support rod 26 and the foot pad 27 to rotate quickly, which is conducive to the synchronous rotation and deployment of multiple support rods 26. At this time, the drone with optical fiber can be quickly deployed in one step, and there is no need to increase the platform height to accommodate the problem of the optical fiber tube being too large, so that the drone body 1 can adapt to a variety of take-off environments.

[0038] The quick deployment device 2 also includes: a rotating plate 28, a T-shaped plate 29 and a third hand screw 210.

[0040] Embodiment 2: In some embodiments, Figure 1-Figure 8 As shown, as a preferred embodiment of the present invention, the optical fiber recovery device 4 includes: a base support frame 41, a rotating pedal 42, a connecting rod 43, a rocker arm 44 and a winding drum 45, the base support frame 41 is arranged on the right side of the UAV body 1, the rotating pedal 42 is rotatably connected to the middle side of the base support frame 41 through a rotating shaft, one end of the connecting rod 43 is rotatably connected to the rear side of the rotating pedal 42 through a rotating shaft, the rocker arm 44 is rotatably connected to the upper side of the base support frame 41, the end of the connecting rod 43 away from the rotating pedal 42 is rotatably connected to the rocker arm 44, and the winding drum 45 is clamped on the left side of the rocker arm 44.

[0041] The two feet are respectively stepped on the two ends of the rotating pedal 42 of the optical fiber recovery device 4, and the left and right feet step on the rotating pedal 42 alternately. The rotating pedal 42 rotates to drive the connecting rod 43 to move, and the movement of the connecting rod 43 drives the rocking arm 44 to rotate continuously.

The other end of the optical fiber connecting line 48 is wound on the sliding frame 311 and then plugged into the interface of the drone body 1. The limiting tube 46 is used to limit the range of movement of the optical fiber connecting line 48 and also plays a protective role to prevent the optical fiber connecting line 48 from being excessively scratched when winding.

[0043] After the drone body 1 returns, the optical fiber cable 48 is removed from the optical fiber module 47. After the optical fiber cable 48 is wound on the winding reel 45, the winding reel 45 continuously rotates to drive the optical fiber cable 48 to be continuously wound on the winding reel 45 to recover the optical fiber cable 48. When the optical fiber cable 48 is scratched on a tree or other place during the flight of the drone body 1, the optical fiber cable 48 cannot be completely recovered.

A torque sensor can be provided at the connection between the winding reel 45 and the rocker arm 44. The torque sensor is used to detect the torque when the winding reel 45 is wound. When the torque reaches a preset value, the operator is reminded to cut the optical fiber cable 48. The information transmitted through the optical fiber cable 48 makes the information transmission of the drone body 1 not easily interfered with by electromagnetic interference, which greatly improves the anti-electromagnetic interference function of the drone body 1.

After the drone body 1 returns from operation, the optical fiber connecting line 48 is removed from the optical fiber module 47. After the optical fiber connecting line 48 is wound on the winding drum 45, the left and right feet step on the rotating pedal 42 alternately. The rotating pedal 42 rotates to drive the connecting rod 43 to move. The movement of the connecting rod 43 drives the rocker arm 44 to rotate continuously. The continuous rotation of the rocker arm 44 drives the winding drum 45 to rotate continuously. The continuous rotation of the winding drum 45 drives the optical fiber connecting line 48 to be continuously wound on the winding drum 45, and the optical fiber connecting line 48 is recovered; Step 3: When the drone body 1 needs to be used again or a new optical fiber connecting line 48 is replaced, loosen the first hand-tightening screw 37, pull out the folding frame 33 from the accommodating frame 31, and the folding frame 33 moves to the right, driving the insertion rod 35 to move to the right. The first tension spring 36 is elastically deformed and stretched. At this time, the folding frame 33 is removed, and the second hand-tightening screw 39 is unscrewed from the connecting plate 312, and the sliding frame 311 is pulled out. The new optical fiber connecting line 48 is inserted into the fixed rod 310 through the sliding frame 311, and the second hand-tightening screw 39 is tightened on the connecting plate 312, and the optical fiber connecting line 48 is pulled out through the extension tube 313 and pulled out, and then penetrates the limiting tube 46 and is plugged into the optical fiber module 47, and then the folding frame 33 is inserted back into the connecting seat 34 through the insertion rod 35, and the first hand-tightening screw 37 is tightened. The replacement of the optical fiber connecting line 48 is completed.
