[0028] like Figure 1 As shown, the drone in this embodiment includes: a drone body 10, a cutting mechanism 20, a driving mechanism 30, and a clamping mechanism 40. The cutting mechanism 20 includes a mounting plate 21, a first cutting blade 22, and a first driving member. The first driving member is disposed on the mounting plate 21, and the first driving member and the first cutting blade 22 drive each other to reciprocate on the mounting plate 21. The driving mechanism 30 includes a first connecting member 31 and a second driving member disposed on the first connecting member 31. The first connecting member 31 is connected to the drone body 10, and the second driving member drives each other with the mounting plate 21 to reciprocate on the mounting plate 21. The clamping mechanism 40 includes a second connecting member 41 and a clamping arm 42. The first end of the second connecting member 41 is rotatably connected to the drone body 10, and the clamping arm 42 is disposed at the second end of the second connecting member 41.

[0029] According to the technical solution of this invention, the drone includes a drone body 10, a cutting mechanism 20, a driving mechanism 30, and a clamping mechanism 40. The cutting mechanism 20 includes a mounting plate 21, a first cutting blade 22 reciprocally mounted on the mounting plate 21, and a first driving member, which drives the first cutting blade 22. The driving mechanism 30 includes a first connecting member 31 and a second driving member. The first connecting member 31 is connected to the drone body 10, and the second driving member is mounted on the first connecting member 31 and drives the mounting plate 21 to reciprocate on the first connecting member 31. The clamping mechanism 40 includes a second connecting member 41 and a clamping arm 42. The first end of the second connecting member 41 is rotatably connected to the drone body 10, and the clamping arm 42 is located at the second end of the second connecting member 41. With the above configuration, when the first cutting blade 22 reciprocates, it can contact the cable surface, thereby cutting the cable. The second driving component can drive the mounting plate 21 to move, which in turn drives the first cutting blade 22 to move. That is, the first cutting blade 22 can move towards the cable, thus cutting the cable and avoiding manual cable cutting by personnel. The second connecting component 41 rotates relative to the drone body 10, which can move the clamping arm 42 to different positions. The clamping arm 42 can clamp the structure near the cable, making the position of the drone body 10 more stable. Therefore, the technical solution of this application effectively solves the problem of high risk when personnel manually cut cables in related technologies.

[0030] In this embodiment, the cable is an overhead cable.

[0031] It should be noted that both the first driving component and the second driving component are first driving motors.

[0032] The structure near the cable can be other cables, or it can be a crossarm, or other structures.

[0033] The mounting plate 21 is provided with a first sliding groove, and the first cutting blade 22 is movably arranged in the first sliding groove.

[0034] The first connecting piece 31 is a first connecting plate, and the mounting plate 21 is further provided with a second sliding groove, and the first connecting plate is arranged in the second sliding groove.

[0035] As shown in the drawings, Figure 2 In this embodiment, the cutting mechanism 20 further comprises a second cutting blade 23 arranged on the mounting plate 21, and the first cutting blade 22 and the second cutting blade 23 are arranged at an acute angle. When the mounting plate 21 moves, the first cutting blade 22 and the second cutting blade 23 can be moved, and then the first cutting blade 22 and the second cutting blade 23 can cut the cable at the same time, improving the cutting efficiency.

[0036] It should be noted that the second cutting blade can also be movably arranged on the mounting plate.

[0037] The mounting plate 21 is provided with a third sliding groove, and the second cutting blade 23 is movably arranged in the third sliding groove.

[0038] The angle between the first cutting blade 22 and the second cutting blade 23 is between 30° and 60°, which can be 30°, 40°, 45°, 50° or 60°.

[0039] As shown in the drawings, Figure 2 In this embodiment, the cutting mechanism 20 further comprises a driving wheel 24 and a transmission wheel 25 engaged with the driving wheel 24, the number of teeth of the transmission wheel 25 is greater than the number of teeth of the driving wheel 24, and the driving wheel 24 and the transmission wheel 25 are rotatably arranged on the mounting plate 21. The driving wheel 24 is arranged on the rotating shaft of the first driving member, the first cutting blade 22 has a transmission tooth part, and the transmission wheel 25 is engaged with the transmission tooth part. The first driving member can drive the driving wheel 24 to rotate, the driving wheel 24 can drive the transmission wheel 25 to rotate, and the transmission wheel 25 can drive the first cutting blade 22 to move. The number of teeth of the transmission wheel 25 is greater than the number of teeth of the driving wheel 24, so that through the driving wheel 24 and the transmission wheel 25, the speed reduction effect can be achieved, and the torque can be increased to ensure that the first cutting blade 22 can smoothly cut the cable.

[0040] The transmission wheel 25 includes two coaxially arranged transmission wheels 25, one of which is in gear transmission with the first cutting blade 22, and the other is in gear transmission with the second cutting blade 23.

[0041] As shown in the drawings, Figures 3 to 5As shown, in this embodiment, the clamping arm 42 includes a first clamping member 421 and a second clamping member 422 spaced apart on the second connector 41. The first clamping member 421 has a first clamping surface, and a clamping space 423 is formed between the first clamping surface and the second clamping member 422. The shape of the first clamping surface can be changed to alter the shape of the clamping space 423. Structures near the cable can enter the clamping space, allowing the first clamping member 421 and the second clamping member 422 to clamp these structures, thus making the drone's position more stable. The shape of the first clamping surface can be changed, enabling the clamping arm 42 to clamp structures of different shapes.

[0042] The second connector 41 includes a second connecting plate, and the first clamping member 421 and the second clamping member 422 are respectively disposed at opposite ends of the second connecting plate.

[0043] The second connector 41 also includes a third connector plate connected to the middle of the second connector plate, and the drone also includes a connector arm connected to the first connector 31, with the third connector plate hinged to the connector arm.

[0044] The third drive motor is mounted on the connecting arm, and the third drive motor drives the third connecting plate to rotate relative to the connecting arm.

[0045] like Figure 3 and Figure 4 As shown, in this embodiment, the second clamping member 422 has a second clamping surface, and a clamping space 423 is formed between the first clamping surface and the second clamping surface. The shape of the second clamping surface can be changed to change the shape of the clamping space 423. The changeable shape of the second clamping surface allows the clamping arm 42 to clamp structures of different shapes.

[0046] like Figure 4As shown, in the embodiment, the first clamping piece 421 comprises a box body 4211, a plurality of clamping rods 4212 arranged in an array, and a plurality of elastic return pieces 4213. The box body 4211 has a mounting space, the plurality of clamping rods 4212 are movably arranged in the mounting space in the direction from the first clamping piece 421 to the second clamping piece 422, one side of the plurality of clamping rods 4212 towards the second clamping piece 422 forms a first clamping surface, and the plurality of elastic return pieces 4213 are arranged one by one corresponding to the plurality of clamping rods 4212. The elastic return piece 4213 is arranged between the clamping rod 4212 and the bottom of the mounting space to move the clamping rod 4212 towards the outside of the box body 4211. The box body 4211 can limit the outer periphery of the plurality of clamping rods 4212. The plurality of clamping rods 4212 are movably arranged in the mounting space in the direction from the first clamping piece 421 to the second clamping piece 422, so that when the first clamping piece 421 contacts the structure near the cable, the clamping rods 4212 at different positions can move different distances, and the shape of the first clamping surface changes, so that the first clamping piece 421 is more fitted with the structure near the cable, and the structure near the cable is clamped. The elastic return piece 4213 can apply an elastic return force to the clamping rod 4212, so that after the clamping rod 4212 is separated from the structure near the cable, the clamping rod 4212 can move towards the second clamping piece 422, and the clamping arm 42 can clamp the structure near the cable again.

[0047] It should be noted that the second clamping piece 422 has the same structure as the first clamping piece 421.

[0048] The elastic return piece 4213 is a compression spring.

[0049] The box body of the first clamping piece 421 and the box body of the second clamping piece 422 are movably connected with the second connecting piece 41, and the rotation of the box body of the first clamping piece 421 and the box body of the second clamping piece 422 is driven by the second driving motor and the straight tooth gear arranged on the rotating shaft of the second driving motor.

[0050] As Figures 3 to 6As shown, in this embodiment, the first clamping member 421 further includes multiple connecting rods 4214, each corresponding to a clamping rod 4212. Each connecting rod 4214 has an elastic reset member 4213 fitted around its outer periphery. The first end of the connecting rod 4214 is connected to the box body 4211, and the second end of the connecting rod 4214 is located inside the clamping rod 4212, which is movably disposed at the second end of the connecting rod 4214. The connecting rod 4214 facilitates the connection between the clamping rod 4212 and the box body. The connecting rod 4214 also limits the elastic reset member 4213 fitted around its outer periphery. The connecting rod 4214 also limits the clamping rod 4212, preventing it from moving outside the box body 4211 and separating from it.

[0051] like Figures 3 to 5 As shown, in this embodiment, the clamping rod 4212 includes a block 42121, which has a receiving space 421211 and a strip-shaped opening 421212 communicating with the receiving space 421211. The minimum radial dimension of the receiving space 421211 is greater than the length of the strip-shaped opening 421212. The connecting rod 4214 includes a strip-shaped rod 42141 and a shaft 42142 connected to the strip-shaped rod 42141. The strip-shaped opening 421212 allows the strip-shaped rod 42141 to pass through. The first end of the shaft 42142 is connected to the strip-shaped rod 42141, and the second end of the shaft 42142 is connected to the housing 4211. The connecting rod 4214 has an installed state and a limiting state. When the connecting rod 4214 is in the installed state, the strip-shaped rod body 42141 is correspondingly arranged with the strip-shaped opening 421212. When the connecting rod 4214 is in the limiting state, the strip-shaped rod body 42141 is located in the receiving space 421211 and is intersected with the strip-shaped opening 421212. The strip-shaped rod body 42141 can enter the receiving space 421211 through the strip-shaped opening 421212 and rotate within the receiving space 421211, so that the strip-shaped rod body 42141 and the strip-shaped opening 421212 are intersected. This allows the block 42121 to limit the strip-shaped rod body 42141, preventing the clamping rod 4212 from separating from the connecting rod 4214 when the clamping rod 4212 moves, and thus preventing the clamping rod 4212 from separating from the box body. The shaft 42142 can be connected to the housing 4211, thus allowing the connecting rod 4214 to be connected to the housing 4211. The minimum radial dimension of the accommodating space 421211 is greater than the length of the strip opening 421212, thus allowing the strip rod 42141 to rotate within the accommodating space 421211 so that the strip rod 42141 and the strip opening 421212 are arranged intersectingly.

[0052] like Figure 3 and Figure 4As shown, in this embodiment, the bottom of the box body 4211 is provided with a plurality of mounting holes 42111, and the second end of the shaft body 42142 is detachably connected with the mounting holes 42111. The shaft body 42142 can be connected with the mounting holes 42111, and then the connecting rod 4214 can be connected with the box body 4211.
