Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tree barrier pruning, and in particular to a UAV pruning device. BACKGROUND

[0002] The line-tree contradiction has been the biggest hidden danger affecting the safe and reliable operation of the distribution network line. Currently, the tree barrier problem is usually solved by manual cutting, but there are problems such as high cost, low efficiency, and great danger. Especially in mountainous areas, it is difficult to clean up, and the line-tree contradiction problem is becoming more and more prominent, which brings great hidden danger to the safe and stable operation of the distribution network line. Currently, there are high-altitude pruning devices on the market, but they are not convenient to operate. They cannot cut thick branches, cannot reach high places, and are affected by lower branches, so manual pruning cannot be performed in many places.

[0003] The patent document with publication number CN108934532A discloses a UAV airborne tree barrier pruning device, which comprises a multi-rotor UAV, a power system, a control system, an insulating support rod, a transmission shaft, a reversing transmission device, a UAV connecting frame, and a cutter head. The power system is fixedly arranged at one end of the insulating support rod, and the reversing transmission device is fixedly arranged at the other end of the insulating support rod. The multi-rotor UAV is fixed to the end of the insulating support rod close to the power system through the UAV connecting frame, and a multi-rotor UAV bracket is arranged on the multi-rotor UAV. The transmission shaft penetrates the inside of the insulating support rod, and one end of the transmission shaft is connected with the power system, and the other end is connected with the reversing transmission device. The cutter head is connected below the reversing transmission device. The control system is electrically connected with the power system, and the power system is also used to drive the multi-rotor UAV. The multi-rotor UAV is used to carry a customized electric saw to the high-altitude tree barrier position, and the power system drives the cutter head to quickly remove the tree barrier or prune the super-high trees.

[0004] The above structure has the problem that the power system cannot adapt to the pruning of branches in different states when driving the cutter head to quickly remove the tree barrier, and the angle adjustment of the cutter head is not flexible enough, resulting in low pruning efficiency.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] like Figures 1-5 As shown, this embodiment of the invention provides a drone trimming device, including a drone body 1 and a trimming mechanism 2. The drone body 1 is used to lift the trimming mechanism 2 into the air and enable it to hover, facilitating the trimming mechanism 2 to trim tree branches. The trimming mechanism 2 includes a clamping assembly 21, a lifting assembly 22, a swinging assembly 23, and a translating trimming assembly 24. The clamping assembly 21 can be clamped onto the UAV body 1; one end of the lifting assembly 22 is fixedly connected to the clamping assembly 21; the swing assembly 23 includes a swing seat 231, a swing drive 232, and a swing rod 233. The swing seat 231 is located at the other end of the lifting assembly 22, and the swing rod 233 is rotatably located on the swing seat 231. The swing drive 232 can drive the swing rod 233 to swing relative to the swing seat 231; the translation and trimming assembly 24 includes a translation member 241 and a trimming member 242. The translation member 241 is connected to the end of the swing member away from the swing seat 231, and the trimming member 242 is connected to the translation member 241. The translation member 241 can drive the trimming member 242 to translate. When the swing rod 233 swings relative to the swing seat 231, the swing rod 233 drives the trimming member 242 to swing around the swing seat 231 through the translation member 241, so that the trimming member 242 can trim tree obstacles at multiple angles. The pruning component 242 is a circular saw, which is equipped with a circular saw blade. The circular saw can drive the circular saw blade to rotate to cut and prune branches.

[0035] In this drone trimming device, after the drone body 1 takes off, it floats horizontally in the air. The swing drive component 232 can drive the swing rod 233 to swing between vertical and horizontal states around the swing seat 231, and can hover at any angle between vertical and horizontal states. Then, through the translation component 241, the trimming component 242 can be driven to trim tree obstacles at different angles between the horizontal and vertical directions. When the swing rod 233 is hovered, the translation component 241 can also drive the trimming component 242 to slide, so that after hovering at any angle, the trimming component 242 can move to the required position of the branch for trimming according to actual needs, without having to adjust the position of the drone body 1, which greatly improves the trimming efficiency. In addition, the lifting component 22 can simultaneously lift and lower the trimming component 242 when lifting and lowering, further improving flexibility when the drone body 1 is stationary.

[0036] Optionally, the drone trimming device further includes a rotary drive 25. A translation component 241 is connected to the end of the swing rod 233 away from the swing base 231 via the rotary drive 25. The rotary drive 25 is fixedly connected to the swing rod 233. The translation component 241 is located at the output end of the rotary drive 25. The rotary drive 25 can drive the translation component 241 to rotate around the axis of the swing rod 233, further adjusting the position and orientation of the trimming component 242, making branch trimming more convenient. The rotary drive 25 is a rotary displacement motor.

[0037] Optionally, such as Figure 3 As shown, the translation component 241 includes a translation connecting frame, a first motor 2411, a rotating lead screw 2412, and a translation seat 2413. The translation connecting frame is connected to the swing rod 233 via a rotating drive component 25, meaning the rotating drive component 25 can drive the translation connecting frame to rotate. The rotating lead screw 2412 is rotatably connected to the translation connecting frame. The translation seat 2413 is threadedly connected to the rotating lead screw 2412. The trimming component 242 is fixedly connected to the translation seat 2413. The first motor 2411 can drive the rotating lead screw 2412 to rotate, thereby driving the translation seat 2413 to move the trimming component 242.

[0038] When the swing rod 233 is in a vertical state, the rotating screw 2412 is parallel to the horizontal direction. When the swing rod 233 is in a horizontal state, the rotating screw 2412 is parallel to the vertical direction. That is, when the swing rod 233 switches between the horizontal and vertical states, it can drive the trimming part 242 to swing and adjust at different angles between the horizontal and vertical directions.

[0039] Furthermore, the translational connecting frame includes an intermediate connecting seat 2414, two lateral connecting rods 2415, and two mounting bases 2416. The intermediate connecting seat 2414 is connected to the swing rod 233 via a rotary drive component 25. One end of each of the two lateral connecting rods 2415 is connected to both ends of the intermediate connecting seat 2414, and the two mounting bases 2416 are connected to the other ends of the two lateral connecting rods 2415. The first motor 2411 is fixedly mounted on one mounting base 2416. One end of the rotating lead screw 2412 is fixedly connected to the output shaft of the first motor 2411 via a coupling, and the other end is rotatably connected to the other mounting base 2416. This structure is reasonably designed, making the assembly and installation of the first motor 2411 and the rotating lead screw 2412 more convenient.

[0040] Optionally, such as Figure 4 As shown, a reinforcing shaft 2412a is provided at the end of the rotating lead screw 2412 that is away from the first motor 2411, and the rotating lead screw 2412 is connected to the mounting base 2416 through the reinforcing shaft 2412a.

[0041] Furthermore, refer to Figure 3The translation connecting frame also includes two limiting stops 2417, with each end of the two limiting stops 2417 connected to two mounting bases 2416 respectively. The two limiting stops 2417 are spaced apart, and the rotating lead screw 2412 is located between the two limiting stops 2417. The translation seat 2413 is threadedly connected to the rotating lead screw 2412 and located between the two limiting stops 2417. In this structure, when the first motor 2411 drives the rotating lead screw 2412 to rotate, the two limiting stops 2417 can prevent the translation seat 2413 from rotating and allow it to translate along the axis of the rotating lead screw 2412.

[0042] Preferably, to prevent branches from getting stuck in the pruning member 242, the translational pruning assembly 24 further includes a clamping member 243, which is disposed on a mounting base 2416. The clamping member 243 is used to clamp the branch when the pruning member 242 prunes the branch, which not only improves the pruning efficiency but also effectively prevents the branch from getting stuck in the pruning member 242.

[0043] Specifically, the clamping member 243 includes a first electric telescopic rod 2431 and an electric clamping arm 2432. The first electric telescopic rod 2431 is fixedly mounted on a mounting base 2416, and the electric clamping arm 2432 can clamp branches. The first electric telescopic rod 2431 can drive the electric clamping arm 2432 to extend or retract. When it is necessary to prune branches, the first electric telescopic rod 2431 drives the electric clamping arm 2432 to extend towards the branch, clamping the branch. The first motor 2411 drives the rotating screw 2412 to rotate, so that the translation seat 2413 moves to the position where the branch needs to be pruned. The first electric telescopic rod 2431 drives the electric clamping arm 2432 to retract and abut against the pruning member 242, which then activates to prune the branch. This structure not only makes branch pruning more convenient but also prevents the pruning member 242 from getting stuck during branch pruning.

[0044] like Figures 1-2 As shown, the swing drive 232 includes a second motor 2321, a winding controller 2322, and a suspension cable 2323. Both the second motor 2321 and the winding controller 2322 are fixedly mounted on the swing base 231. One end of the suspension cable 2323 is connected to the winding end of the winding controller 2322, and the other end is connected to the swing rod 233. The second motor 2321 can control the winding controller 2322 to wind or unwind the suspension cable 2323. When the winding controller 2322 is fully unwound, the rotating screw 2412 is parallel to the horizontal direction; when the winding controller 2322 is fully wound, the rotating screw 2412 is parallel to the vertical direction. The use of the suspension cable 2323 in this structure makes the structure more stable, effectively avoiding insufficient support strength of the output shaft of the second motor 2321, and ensuring stable operation.

[0045] likeFigure 5 As shown, the clamping assembly 21 includes a clamping control base 211, two sets of elastic retractable rods 212, and two clamping blocks 213. The two sets of elastic retractable rods 212 are elastically and telescopically disposed at both ends of the clamping control base 211, and the two clamping blocks 213 are respectively disposed at the two ends of the two sets of elastic retractable rods 212 away from the clamping control base 211. Under the elastic force of the two sets of elastic retractable rods 212, the two clamping blocks 213 can be clamped onto the drone body 1. In use, the clamping assembly can be stretched backward along the axial direction of the elastic retractable rods 212, and then the drone body 1 can be placed between the two clamping blocks 213 and the clamping blocks 213 can be released. The two clamping blocks 213 clamp the drone body 1 under the elastic action of the two sets of elastic retractable rods 212, making the operation very convenient.

[0046] To further improve the connection strength between the clamping assembly 21 and the drone body 1, a vacuum generator 2131 and a vacuum suction cup 2132 are provided on the clamping block 213. The clamping block 213 is provided with a suction cup hole, and the vacuum suction cup 2132 is connected to the suction cup hole. When the two clamping blocks 213 are clamped on the smooth side walls on both sides of the drone body 1, the vacuum generator 2131 can be connected to the air circuit system to make the vacuum generator 2131 work. The vacuum generator 2131 draws air from the vacuum suction cup 2132 through the suction cup hole to generate negative pressure, so that the vacuum suction cup 2132 is firmly attached to the drone body 1.

[0047] The lifting assembly 22 includes a second electric telescopic rod 221 and an L-shaped connecting rod 222. The second electric telescopic rod 221 is vertically fixedly connected to the clamping control seat 211. The L-shaped connecting rod 222 includes a first connecting rod and a second connecting rod that are perpendicularly connected to each other. The end of the first connecting rod opposite to the second connecting rod is connected to the second electric telescopic rod 221, and the end of the second connecting rod opposite to the first connecting rod is fixedly connected to the swing seat 231. The second electric telescopic rod 221 can drive the L-shaped connecting rod 222 to lift and lower. The L-shaped connecting rod 222 can extend the trimmer 242 toward the outside of the UAV body 1 to facilitate the trimming of tree branches.

[0048] Example 2

[0049] The drone trimming device provided in this embodiment has a structure that is basically the same as that in Embodiment 1. For convenience, only the differences are described here. The differences are as follows:

[0050] The swing drive 232 includes a second motor 2321, a first gear and a second gear. The second motor 2321 is fixedly mounted on the swing base 231. The first gear is mounted on the output shaft of the second motor 2321. The second gear is mounted on the swing rod 233 at one end near the swing base 231. The first gear and the second gear mesh. When the second motor 2321 drives the first gear to rotate, it can drive the second gear to rotate at the same time, thereby realizing the swing of the swing rod 233.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
