[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1: In the present invention, the two mounting bars move in opposite directions to twist the female head of the nickel metal internal thread connector, thereby loosening the female head of the nickel metal internal thread connector from the male head of the nickel metal external thread connector, and at the same time cooperate with the multi-stage electric telescopic rod to push the two arc-shaped plates to move away from the external RF transmitter body, thereby disconnecting the female head of the nickel metal internal thread connector from the male head of the nickel metal external thread connector, and disconnecting the antenna from the external RF transmitter body.

[0020] 2: In the present invention, a damaged antenna can be disassembled and temporarily stored in a collection tank during the flight of the UAV. The damaged antenna can be collected and temporarily stored, which is convenient for later detection and repair of the damaged antenna and detection of the cause of damage to the antenna. The damaged antenna can be disassembled during the flight of the UAV and replaced with a new spare antenna. The UAV can achieve non-stop replacement of the antenna during flight. The UAV does not need to fly to a base station for maintenance before replacing the antenna. The damaged antenna can be disassembled and replaced with a new spare antenna during the flight of the UAV, ensuring the normal operation of the external RF transmitter body of the UAV during flight.

[0021] 3: In the present invention, one of the mounting bars is used to push the nickel metal internal thread connector female head of the spare antenna to detect whether the nickel metal internal thread connector female head shakes under the push of one of the mounting bars. If the vibration sensor detects vibration, the antenna vibrates, and it is determined that the connection between the nickel metal internal thread connector female head and the nickel metal external thread connector male head is unstable, and the connection between the nickel metal external thread connector male head and the nickel metal internal thread connector female head is loose. If the vibration sensor cannot detect vibration, it is determined that the connection between the nickel metal external thread connector male head and the nickel metal internal thread connector female head is stable. This method can not only detect whether the connection is firm and stable after replacing the spare antenna, but also detect whether the installation of the antenna is stable during the flight of the drone.

[0022] 4: In the present invention, two mounting bars are used to clamp and fix the nickel metal internal thread connector female head, and the two mounting bars can also be used to provide a supporting force for the nickel metal internal thread connector female head and the antenna, so as to avoid the phenomenon that the nickel metal internal thread connector female head and the nickel metal external thread connector male head are broken due to the wind when the drone is blown by strong winds in windy weather, and the stability of the connection between the nickel metal internal thread connector female head and the nickel metal external thread connector male head can be increased.

[0023] 5: In the present invention, a wiping sponge pad is used to absorb rainwater on the outer wall of the antenna, and a wiping sponge pad is used to wipe and remove dust and impurities on the outer wall of the antenna. The rainwater on the outer wall of the antenna and the dust and impurities attached to the outer wall of the antenna can be removed to ensure the cleanliness of the antenna, thereby ensuring the normal operation of the antenna. The antenna can be cleaned and the surface of the antenna can be kept dry to prevent rainwater from corroding the antenna and affecting the normal use of the antenna.

[0041] As a technical optimization solution of the present invention, an installation groove is opened on the outer wall of the antenna 8, and a vibration sensor 17 is installed in the installation groove. The vibration sensor 17 is electrically connected to the PLC controller 4.

[0042] As a technical optimization scheme of the present invention, a storage groove 9 and a collection groove 10 are symmetrically opened on one side of the external RF transmitter body 1 close to the strip plate 3, and a fourth electric push rod 34 is installed on the inner walls of the storage groove 9 and the collection groove 10, and a mounting plate 35 is installed at the end of the piston rod of the fourth electric push rod 34, and an electromagnet 36 is installed on the side of the mounting plate 35 away from the fourth electric push rod 34, and the fourth electric push rod 34 and the electromagnet 36 are both electrically connected to the PLC controller 4.

Both the first electric gate 6 and the second electric gate 7 are electrically connected to the PLC controller 4 .

[0044] As a technical optimization solution of the present invention, a spare antenna of the external RF transmitter body 1 is loaded in the storage slot 9 .

[0045] As a technical optimization solution of the present invention, the rotating column 13 is located between the storage tank 9 and the collecting tank 10 , and the storage tank 9 and the collecting tank 10 are located between the two strip plates 3 .

[0046] As a technical optimization solution of the present invention, a mounting plate 2 is installed on the side of the external RF transmitter body 1 away from the strip plate 3, and a mounting hole is opened on the side of the mounting plate 2. The mounting hole on the side of the mounting plate 2 can facilitate the connection between the external RF transmitter body 1 and the drone.

[0047] When the present invention is in use, the device is mounted on the drone via the mounting plate 2 so that the antenna 8 and the rotating column 13 are in a mutually perpendicular state.

[0048] The collision detection sensor 5 installed on the strip plate 3 is used to detect whether the strip plate 3 collides. When the drone collides with a flying bird during flight or collides with the ground when landing, the drone vibrates, driving the external RF transmitter body 1 and the strip plate 3 to vibrate. The collision detection sensor 5 can detect the collision of the drone. At this time, the collision detection sensor 5 can be used to transmit the signal to the PLC controller 4. The PLC controller 4 controls the two first electric sliders 19 to move on the first guide rail 18, so that the rotating column 13 is between the two first electric push rods 21. The piston rods of the two first electric push rods 21 push the mounting block 22 to move, thereby moving the two mounting bars 24, so that one mounting bar 24 can be located directly above the rotating column 13, and the other mounting bar 24 can be located directly below the rotating column 13. At this time, starting the two second electric push rods 23 can make the two mounting bars 24 move closer to each other until the anti-slip rubber strips 25 on the opposite sides of the two mounting bars 24 are aligned with the anti-slip rubber strips 25 on the opposite sides of the two mounting bars 24. The outer wall of the rotating column 13 is in contact with each other. At this time, the two first electric sliders 19 are started again at the same time. The two first electric sliders 19 move in opposite directions, so that the two mounting bars 24 can move in opposite directions. Then, the two mounting bars 24 move in opposite directions to rotate the rotating column 13. The rotation of the rotating column 13 can drive the two fixing plates 14 to rotate, thereby rotating the antenna 8. The antenna 8 can be rotated until the end of the antenna 8 faces directly upward. At this time, the piston rods of the two second electric push rods 23 retract, so that the two mounting bars 24 move away from each other, so that the mounting bar 24 is out of contact with the rotating column 13. At this time, the first electric push rod 21 located at the top is started. The piston rod of the first electric push rod 21 pushes the mounting block 22 and the mounting bar 24 to move closer to the antenna 8. The mounting bar 24 contacts the antenna 8 during the movement, and as the mounting bar 24 continues to move away from the external RF transmitter body 1, the mounting bar 24 can be used to push the antenna 8 until the antenna 8 is pushed to a horizontal state and then stops.At this time, the PLC controller 4 can control the two first electric sliders 19 to move on the two first guide rails 18, and move the two mounting bars 24 to one being directly above the nickel metal internal thread connector female head 12 and the other being directly below the nickel metal internal thread connector female head 12, and the PLC controller 4 simultaneously controls the two second electric sliders 27 to move on the two second guide rails 26, so that the rotating column 13 is between the two multi-stage electric telescopic rods 28, and the rotating column 13 is between the two first electric push rods 21, the PLC controller 4 controls the piston rods of the two multi-stage electric telescopic rods 28 to extend, so that the third electric push rod 30 moves away from the external RF transmitter body 1, and starting the third electric push rod 30 can make the two arc plates 32 move closer to each other, and the antenna 8 can be clamped by the two arc plates 32, and the antenna 8 can be clamped between the two arc plates 32. At this time, the two mounting bars 24 move closer to each other. The two first electric sliders 19 move in opposite directions to contact the nickel metal internal thread connector female head 12. At this time, the two first electric sliders 19 move in opposite directions, so that the two mounting bars 24 move in opposite directions to twist the nickel metal internal thread connector female head 12, thereby loosening the nickel metal internal thread connector female head 12 from the nickel metal external thread connector male head 11, and at the same time, the multi-stage electric telescopic rod 28 pushes the two arc plates 32 to move away from the external RF transmitter body 1, thereby disconnecting the nickel metal internal thread connector female head 12 from the nickel metal external thread connector male head 11, and disconnecting the antenna 8 from the external RF transmitter body 1. When the drone collides with a flying bird or the drone collides with the ground when landing, the antenna 8 can be quickly disconnected from the external RF transmitter body 1, so as to avoid the connection between the antenna 8 and the external RF transmitter body 1 being broken and damaged due to large vibration of the drone and the external RF transmitter body 1. ;

[0049] After the vibration of the UAV and the external RF transmitter body 1 ends, the two first electric sliders 19 can be started again to move closer to each other on the first guide rail 18, so that the two mounting bars 24 can screw the nickel metal internal thread connector female head 12 again, and cooperate with the two multi-stage electric telescopic rods 28 to make the antenna 8 gradually approach the external RF transmitter body 1, and the nickel metal internal thread connector female head 12 can be screwed again to connect the nickel metal internal thread connector female head 12 with the nickel metal external thread connector male head 11 again, so that the antenna 8 is connected to the external RF transmitter body 1. When the UAV and the external RF transmitter body 1 vibrate greatly, the antenna 8 can be quickly disconnected from the external RF transmitter body 1 to avoid the connection between the antenna 8 and the external RF transmitter body 1 from being broken and damaged. After the vibration of the UAV and the external RF transmitter body 1 ends, the antenna 8 is connected to the external RF transmitter body 1 again to maintain normal use.

[0050] In addition, by utilizing the two mounting bars 24 to contact the rotating column 13 and utilizing the two mounting bars 24 to move in opposite directions, the rotating column 13 can be twisted to rotate the rotating column 13. The rotation of the rotating column 13 can drive the two fixing plates 14 to rotate, thereby changing the angle of the antenna 8. The angle of the antenna 8 can be adjusted in real time. The direction of the antenna 8 can be adjusted in real time when the UAV is flying. When the antenna 8 is rotated to face upward, the mounting bar 24 can be used to move away from the external RF transmitter body 1 to push the antenna 8. Thus, the orientation angle of the antenna 8 can be adjusted. The orientation angle of the antenna 8 can be adjusted in real time during the flight of the UAV.

[0051] Moreover, in windy weather, the orientation angle of the antenna 8 can be adjusted. The orientation angle of the antenna 8 can be adjusted along the wind direction according to the wind direction, thereby reducing the force exerted on the antenna 8 by the wind, avoiding the problem of the connection between the antenna 8 and the external RF transmitter body 1 being broken due to the shaking of the antenna 8 caused by the strong wind, thereby improving the protection of the connection between the antenna 8 and the external RF transmitter body 1, and the orientation angle of the antenna 8 along the wind direction can also reduce the wind resistance exerted on the antenna 8, thereby reducing the impact of strong winds on the antenna 8.

[0052] When it rains and dust impurities in the rain and air adhere to the antenna 8 and affect the normal use of the antenna 8, the antenna 8 can be pushed to a horizontal state by using the mounting strip 24 first, and the wiping sponge pads 33 installed on the opposite surfaces of the two arc-shaped plates 32 are used to contact the outer wall of the antenna 8 without clamping the antenna 8, that is, the antenna 8 is not subjected to force, and the two mounting strips 24 are used to move in opposite directions to twist the rotating column 13, so that the rotating column 13 drives the fixing plate 14 and the antenna 8 to rotate, while the nickel metal internal thread connector female head 12 remains stationary. At this time, The rotating antenna 8 can generate friction with the wiping sponge pad 33 during the rotation process, and the wiping sponge pad 33 is used to absorb rainwater on the outer wall of the antenna 8, and the wiping sponge pad 33 is used to wipe and remove dust and impurities on the outer wall of the antenna 8. The rainwater on the outer wall of the antenna 8 and the dust and impurities attached to the outer wall of the antenna 8 can be removed to ensure the cleanliness of the antenna 8, and then ensure the normal operation of the antenna 8. The antenna 8 can be cleaned and the surface of the antenna 8 can be kept dry to prevent rainwater from corroding the antenna 8 and affecting the normal use of the antenna 8.

[0053] When the antenna 8 is damaged during the flight of the drone, the antenna 8 can be adjusted to a horizontal state using the mounting strip 24, and then the antenna 8 can be clamped and fixed between the two arc plates 32 by using the two mounting strips 24 to move in opposite directions to twist the nickel metal internal thread connector female head 12, and the multi-stage electric telescopic rod 28 can be used to push the arc plate 32 to move away from the external RF transmitter body 1, so that the nickel metal internal thread connector female head 12 can be unscrewed from the nickel metal external thread connector male head 11, thereby making the nickel metal internal thread connector female head 11 2 is disconnected from the male connector 11 of the nickel metal external thread. At this time, the two second electric sliders 27 are started, and the two second electric sliders 27 move in the same direction, so that the antenna 8 clamped and fixed by the two arc plates 32 can follow the two second electric sliders 27 to move horizontally, so that the antenna 8 can move to the right side of the collecting tank 10, open the second electric gate 7 in the collecting tank 10, and start the fourth electric push rod 34 in the collecting tank 10. The fourth electric push rod 34 in the collecting tank 10 pushes the mounting plate 35 to move closer to the antenna 8. When the antenna 8 moves to the right side of the collecting tank 10, The nickel metal internal thread connector female head 12 follows the antenna 8 to move to the right side of the collecting tank 10, and the nickel metal internal thread connector female head 12 is located between the mounting plate 35 and the antenna 8. The electromagnet 36 on the side of the mounting plate 35 first contacts the nickel metal internal thread connector female head 12, and the electromagnet 36 is started to adsorb the nickel metal internal thread connector female head 12, and then the nickel metal internal thread connector female head 12 can be adsorbed and fixed on the electromagnet 36. At this time, the two arc plates 32 move away from each other to loosen the clamping fixation of the antenna 8, and the electromagnet 36 is used to adsorb the nickel metal internal thread connector female head 12. The antenna 8 can be fixed by adsorption. At this time, the fourth electric push rod 34 in the collecting tank 10 is started, so that the piston rod of the fourth electric push rod 34 in the collecting tank 10 is retracted, and the nickel metal internal thread connector female head 12 and the antenna 8 can be moved into the collecting tank 10. The damaged antenna 8 can be disassembled and transported to the collecting tank 10. The damaged antenna 8 can be disassembled and temporarily stored in the collecting tank 10 during the flight of the UAV. The damaged antenna 8 can be collected and temporarily stored, which is convenient for later detection and maintenance of the damaged antenna 8 and detection of the cause of damage to the antenna 8.

[0054] After the damaged antenna 8 is disassembled and transported to the collection tank 10, the two second electric sliders 27 are started again, so that the two second electric sliders 27 drive the two arc plates 32 to move to the side of the storage tank 9, open the first electric gate 6 in the storage tank 9, and start the fourth electric push rod 34 in the storage tank 9. The fourth electric push rod 34 in the storage tank 9 can push the mounting plate 35, the electromagnet 36, and the nickel metal internal thread connector female head 12 of the spare antenna adsorbed and fixed by the electromagnet 36 to move until the spare antenna is moved out of the storage tank 9, and the spare antenna moves out of the storage tank 9. The backup antenna is inserted between the two arc-shaped plates 32. When the backup antenna is completely moved out of the storage slot 9, the two arc-shaped plates 32 move closer to each other to clamp and fix the backup antenna. The electromagnet 36 in the storage slot 9 can be turned off to loosen the adsorption and fixation of the nickel metal internal thread connector female head 12 of the backup antenna, thereby loosening the fixation of the backup antenna. At this time, the two second electric sliders 27 can be used to move the backup antenna to the positive side of the nickel metal external thread connector male head 11, and the piston rod of the multi-stage electric telescopic rod 28 can be retracted to make the nickel metal internal thread connector of the backup antenna clamped and fixed by the two arc-shaped plates 32 be released. The female connector 12 approaches the nickel metal external thread connector male 11 until the nickel metal internal thread connector female 12 contacts the nickel metal external thread connector male 11 and the nickel metal internal thread connector female 12 is sleeved on the nickel metal external thread connector male 11. The two mounting strips 24 are used to twist the nickel metal internal thread connector female 12 of the backup antenna again, and the piston rod of the multi-stage electric telescopic rod 28 is retracted to make the backup antenna and the nickel metal internal thread connector female 12 of the backup antenna gradually move closer to the nickel metal external thread connector male 11, so that the nickel metal of the backup antenna can be moved closer to the nickel metal external thread connector male 11. The female internal thread connector 12 is connected to the male nickel metal external thread connector 11, and then the spare antenna is connected to the external RF transmitter body 1. The damaged antenna 8 can be disassembled and replaced with a new spare antenna during the flight of the UAV. The UAV can replace the antenna 8 without stopping during the flight. The UAV does not need to fly to the base station for maintenance before replacing the antenna 8. The damaged antenna 8 can be disassembled and replaced with a new spare antenna during the flight of the UAV, ensuring the normal operation of the external RF transmitter body 1 of the UAV during the flight.

[0055] And after the backup antenna is connected to the external RF transmitter body 1, one of the mounting bars 24 can be used to push the nickel metal internal thread connector female head 12 of the backup antenna to detect whether the nickel metal internal thread connector female head 12 shakes under the push of one of the mounting bars 24. If the vibration sensor 17 detects vibration, the antenna 8 vibrates, and it is determined that the connection between the nickel metal internal thread connector female head 12 and the nickel metal external thread connector male head 11 is unstable, and the connection between the nickel metal external thread connector male head 11 and the nickel metal internal thread connector female head 12 is loose. If the vibration sensor 17 cannot detect vibration, it is determined that the connection between the nickel metal external thread connector male head 11 and the nickel metal internal thread connector female head 12 is stable. Not only can it be detected whether the connection is firm and stable after replacing the backup antenna, but also whether the installation of the antenna 8 is stable during the flight of the drone can be detected.

[0056] Furthermore, when the UAV flies in windy weather, the two mounting strips 24 are used to clamp and fix the nickel metal internal thread connector female head 12. The two mounting strips 24 can also be used to provide a supporting force for the nickel metal internal thread connector female head 12 and the antenna 8 to avoid the phenomenon that the nickel metal internal thread connector female head 12 and the nickel metal external thread connector male head 11 are broken due to the strong wind blowing the UAV in windy weather, and the stability of the connection between the nickel metal internal thread connector female head 12 and the nickel metal external thread connector male head 11 can be increased.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
