[0055] See also Figure 1-Figure 8 , the present invention provides a technical solution:

[0056] A signal line mounting fixture for a power distribution line comprises: a mounting device 1 and a clamping mechanism 2, wherein the mounting device 1 is fixed to the lower side of a drone 3, and the clamping mechanism 2 can be detachably suspended below the mounting device 1, wherein the clamping mechanism 2 is fixedly connected to an alligator clip 4, and the alligator clip 4 is connected to a signal line. When the signal line is mounted, the drone 3 brings the mounting device 1 and the clamping mechanism 2 to the top of the power distribution line, the clamping mechanism 2 is closed, so that the alligator clip 4 clamps the power distribution line, and the mounting device 1 is separated from the clamping mechanism 2. At this time, the signal line is mounted and the drone 3 can return with the mounting device 1 or perform the next task. After the inspection is completed, the drone 3 flies back to the clamping mechanism 2 with the mounting device 1, and the mounting device 1 is connected to the clamping mechanism 2. At this time, the clamping mechanism 2 opens, so that the alligator clip 4 releases the power distribution line, and the drone 3 returns with the mounting device 1 and the clamping mechanism 2. The power distribution line signal line mounting fixture of the present application can be remotely controlled and does not require people to climb the pole tower for mounting. The mounting efficiency is relatively high and it can still be successfully mounted in environments such as rivers and valleys. This solves the problem of the prior art of manually climbing the pole tower for mounting, which is greatly affected by the environment, has low efficiency, and poses a potential safety hazard to personnel.

[0057] The clamp mechanism 2 includes: a fixed housing 21, a power supply 22, a motor 23, a connecting rod mechanism 24 and a clamp 25; the fixed housing 21 can be detachably suspended below the mounting device 1, the fixed housing 21 is fixedly connected to the power supply 22 and the motor 23, the power supply 22 is connected to the motor 23 through a wire to supply power to the motor, a switch is arranged between the power supply 22 and the electrode 23, the switch can receive a ground remote control signal to make the motor rotate forward, rotate reversely, or stop; the connecting rod mechanism 24 is connected to the fixed housing 21, the motor 23 is connected to the connecting rod mechanism 24, the motor 23 can drive the connecting rod mechanism 24 to move, the clamp 25 is connected to the connecting rod mechanism 24, the motor 23 drives the clamp 25 to move through the connecting rod mechanism 24. The crocodile clip 4 is fixedly connected to the inner side of the clamp 25, when the clamp 25 moves toward each other, it drives the crocodile clip 4 to clamp the power distribution line, and when the clamp 25 moves in the opposite direction, it drives the crocodile clip 4 to loosen the power distribution line.

[0058] The connecting rod mechanism 24 includes: a vertical rod 241, a horizontal rod 242, a first connecting rod 243, a second connecting rod 244 and a third connecting rod 245;

[0059] The vertical rod 241 is fixedly connected to the output shaft of the motor 23. The vertical rod 241 and the output shaft of the motor 23 can be connected by a pin. The outer surface of the vertical rod 241 is provided with a thread.

[0060] An internal threaded hole is provided in the middle of the cross bar 242, and the external thread of the vertical bar 241 cooperates with the internal thread of the cross bar 242. When the output shaft of the motor 23 drives the vertical bar 241 to rotate, the cross bar 242 will move up and down. Both ends of the cross bar 242 are hinged with the first connecting rod 243, and the up and down movement of the cross bar 242 will drive the first connecting rod 243 to move.

[0061] The second connecting rod 244 is composed of a first rod 2441 and a second rod 2442. The first rod 2441 and the second rod 2442 form a V shape. The angle between the first rod 2441 and the second rod 2442 is 90°-150°. The bending portion of the second connecting rod 244 is hinged to the fixed housing 21 at the first hinge hole 211. The end of the first rod 2441 away from the bending portion is hinged to the clamping claw 25 at the third hinge hole 246. The end of the second rod 2442 away from the bending portion is hinged to the first connecting rod 243.

[0062] One end of the third connecting rod 245 is hinged to the fixed housing 21 at the second hinge hole 212, and the other end is hinged to the clamping claw 25 at the fourth hinge hole 247;

[0063] When the cross bar 242 moves downward, it drives the right first link 243 to move, and the right first link 243 drives the right second link 244 to rotate counterclockwise around the first hinge hole 211, and the right second link 244 drives the right clamping jaw 25 to move outward, so that the clamping jaw 25 is in a relaxed state. At this time, the clamping jaw mechanism 2 will be Figure 3 The status changes to Figure 4 status.

[0064] When the cross bar 242 moves upward, it drives the right first link 243 to move, and the right first link 243 drives the right second link 244 to rotate clockwise around the first hinge hole 211, and the right second link 244 drives the right clamping claw 25 to move inward, so that the clamping claw 25 is in a clamping state. At this time, the clamping claw mechanism 2 will be Figure 4 The status changes to Figure 3 status.

[0065] The number of the first connecting rod 243, the second connecting rod 244, the third connecting rod 245 and the clamping jaws 25 is 2, and they are symmetrically arranged relative to the vertical rod 241. In this way, when clamping, the two clamping jaws 25 move toward each other at the same time to clamp the power distribution line. If the number of the first connecting rod 243, the second connecting rod 244, the third connecting rod 245 and the clamping jaws 25 is 1, a fixing block needs to be arranged on the housing 21 to cooperate with the clamping jaws 25 to clamp the power distribution line.

[0066] The third connecting rod 245 has the same length as the first rod 2441. The distance L1 between the first hinge hole 211 and the second hinge hole 212 is equal to the distance L2 between the third hinge hole 246 and the fourth hinge hole 247. In this way, the third connecting rod 245, the first rod 2441, L1 and L2 form a parallelogram connecting rod mechanism, and the clockwise rotation of the right first rod 2441 will drive the clamping jaw 25 to move to the lower left, and the counterclockwise rotation of the right first rod 2441 will drive the clamping jaw 25 to move to the upper right.

[0067] The clamping jaws 25 include a clamping portion 251, which is located on the inner side of the two clamping jaws 25, and the crocodile clip 4 is fixed on the inner side of the clamping portion 251; thus, when clamping the distribution line, the crocodile clip 4 contacts the distribution line, and since the crocodile clip 4 is connected to the signal line, the signal line is connected to the distribution line.

[0068] The angle α between the clamping portion 251 and the line connecting the third hinge hole 246 and the fourth hinge hole 247 is equal to the angle β between the line connecting the first hinge hole 211 and the second hinge hole 212 and the vertical direction. Since the third connecting rod 245, the first rod 2441, L1 and L2 form a parallelogram connecting rod mechanism, and α is equal to β, the clamping portion 251 should be vertical. In this way, when clamping distribution lines of different thicknesses, the clamping portion 251 is kept vertical, so that it is convenient to adapt to distribution lines of different thicknesses, and the clamping process is more stable.

[0069] Although all drones currently used in aerial operations are equipped with cameras, operators can observe the distribution line through the cameras, but due to the relatively small distance between the clamping parts 251, it is difficult for the drone to accurately dock the gap between the clamping parts 251 and the distribution line in the air, so the clamping jaws 25 also include a guide part 252, and the guide parts 252 of the two clamping jaws 25 are in an inverted V shape. The distance between the lower ends of the guide parts of the two clamping jaws 25 is relatively large, and the drone can easily dock the guide parts to the distribution line. Under the guiding effect of the guide part 252, it is easy to accurately dock the clamping part 251 with the distribution line.

[0070] In order to facilitate the clamping mechanism 2 to be easily suspended by the mounting device 1 after completing the work, a counterweight block 253 is set at the lower end of the clamping jaw 25. In this way, after the clamping mechanism 2 clamps the distribution line, the clamping mechanism 2 can still maintain its original posture under the action of gravity, and will not be skewed or inverted, which is convenient for the mounting device 1 to suspend it and be taken away after releasing the distribution line.

[0071] A weight-reducing groove 254 is provided in the middle of the clamp 25 . The weight-reducing groove 254 can be distributed on both sides of the clamp 25 and avoid the clamping portion 251 , the guide portion 252 , the counterweight block 253 and the hinge position, thereby reducing the weight of the drone while ensuring strength.

[0072] The mounting device 1 includes an interface 11 and an electromagnet 12. The interface 11 can be detachably connected to the drone body. The structure of the interface 11 can be adaptively adjusted according to the interface shape of different drones. The electromagnet 12 is fixed on the lower side of the interface 11. The on and off of the electromagnet can be controlled to suspend or release the clamping mechanism 2. This suspension method is simple and has strong adaptability. The suction force of the electromagnet can attract objects to put the objects in the best position and angle.

[0073] In order to further ensure the suction force of the electromagnet, the clamping mechanism 2 also includes an armature 26; in order to ensure that the electromagnet can easily attract the armature 26, the armature 26 is arranged at the upper end of the clamping mechanism 2, so that the electromagnet 12 under the drone can be easily attracted to the armature 26.

[0074] The working process of one embodiment of the present invention is as follows:

[0075] The drone carries the mounting device 1 and the clamping mechanism 2 to go above the power distribution line that needs to be repaired. At this time, the clamping claw 25 is in a loose state. Figure 4 As shown, the drone moves downward, and under the guidance of the guide part 252, the drone makes the clamping parts 251 of the two clamps located on both sides of the power distribution line respectively. At this time, the motor 23 is energized, the motor 23 drives the vertical rod 241 to rotate, the vertical rod drives the horizontal rod 242 to move upward, the horizontal rod 242 drives the first connecting rod 243 to move, the right first connecting rod 243 drives the right second connecting rod 244 to rotate clockwise around the first hinge hole 211, and the right second connecting rod 244 will drive the right clamping claw 25 to move inward, so that the clamping claw 25 is in a clamped state. At this time, the clamping claw mechanism 2 will be Figure 4 The status changes to Figure 3 When the clamp 25 clamps the power distribution line, the alligator clip 4 contacts the power distribution line. Since the alligator clip 4 is connected to the signal line, the signal line is connected to the power distribution line. At this time, the electromagnet 12 of the drone mounting device 1 is powered off, the drone carrying the mounting device 1 returns, and the clamp mechanism 2 clamps on the power distribution line to perform maintenance work.

[0076] After the inspection is completed, the UAV returns to the position of the clamping mechanism 2, and the electromagnet 12 is energized. After the electromagnet 12 and the armature 26 are attracted, the motor 23 is energized, and the motor 23 drives the vertical rod 241 to rotate in the opposite direction, and the vertical rod drives the cross bar 242 to move downward, and the cross bar 242 drives the first connecting rod 243 to move, and the first connecting rod 243 on the right side drives the second connecting rod 244 on the right side to rotate counterclockwise around the first hinge hole 211, and the second connecting rod 244 on the right side will drive the right clamping claw 25 to move outward, so that the clamping claw 25 releases the power distribution line. At this time, the UAV can carry the mounting device 1 and the clamping claw mechanism 2.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
