[0039] Various embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0040] This utility model provides a tree trimming device based on a drone, see [link to relevant documentation]. Figure 1 and Figure 2 The tree trimming device based on a drone includes: a drone 1, an installation component 3, and a trimming component 2. The installation component 3 is located at the bottom of the drone 1's body 11; the trimming component 2 is mounted on the installation component 3. The trimming component 2 includes a lifting mechanism, a fixed base 24, a rotating mechanism, a telescopic arm 26, and an electric saw 27. The lifting mechanism is fixedly connected to the installation component 3, and the fixed base 24 is connected to the lifting mechanism, which drives the fixed base 24 to move up and down. The telescopic arm 26 is rotatably connected to the fixed base 24, and the rotating mechanism is located on the fixed base 24 and connected to the telescopic arm 26, driving the telescopic arm 26 to swing up and down. The telescopic arm 26 includes an outer tube 261 and a telescopic plate 262 slidably connected within the outer tube 261. A telescopic arm drive mechanism for extending or retracting the telescopic arm 26 is provided between the outer tube 261 and the telescopic plate 262. The electric saw 27 is mounted on the telescopic plate 262 of the telescopic arm 26.

[0041] Specifically, the drone 1 includes a body 11 and several blades 12 mounted on top of the body 11 for controlling its flight. The trimming assembly 2 is mounted on the drone 1 via a mounting assembly 3. After the drone 1, carrying the trimming assembly 2, flies to the location of the tree obstruction to be trimmed, the attitude of the chainsaw 27 can be automatically adjusted via a lifting mechanism, a rotating mechanism, and a telescopic arm drive mechanism, precisely adjusting the angle and position of the chainsaw blade to ensure trimming accuracy. In this embodiment, two support frames 4 are provided at the bottom of the drone 1's body 11 for supporting the body 11. The two support frames 4 are symmetrically arranged at the bottom of the drone 1's body 11, and the mounting assembly 3 is located at the center of the bottom of the drone 1's body 11 and between the two support frames 4. Specifically, the support frame 4 has a "U"-shaped structure, and a mounting plate is provided on the top of the support frame 4. The mounting plate can be fixedly connected to the bottom of the drone 1's body 11 with screws. By setting up the support frame 4, the drone 1 can be supported when it lands on the ground. At this time, the mounting component 3 and the trimming component 2 are at a certain distance from the ground, thus allowing the tree trimming device based on the drone to be stably parked on the ground. In this embodiment, two trimming components 2 are installed on the mounting component 3, and the two trimming components 2 are symmetrically arranged on both sides of the mounting component 3. By setting up two trimming components 2, on the one hand, the drone 1 can more easily maintain balance during flight, and on the other hand, it can trim the tree obstacles in two directions simultaneously, improving trimming efficiency.

[0042] Specifically, see Figure 3 and Figure 4 The lifting mechanism includes a connecting frame 21, a lead screw 22, a guide rod 214, and a lifting drive motor 23. The connecting frame 21 has a rectangular frame structure, including two horizontal frames 211 and two vertical frames 212. A guide rod 214 is provided between the two horizontal frames 211, and the fixed seat 24 is slidably connected to the guide rod 214. The upper and lower ends of the lead screw 22 are rotatably connected to the two horizontal frames 211, respectively. The lifting drive motor 23 is located outside the bottom horizontal frame 211 of the connecting frame 21 and is connected to the lead screw 22. The lifting drive motor 23 is used to drive the lead screw 22 to rotate. The fixed seat 24 is screwed onto the lead screw 22.

[0043] In this embodiment, there are two guide rods 214, which are symmetrically arranged on the left and right sides of the lead screw 22. The cross-section of the guide rod 214 is rectangular. When the lead screw 22 drives the fixed seat 24 to move up and down, the guide rod 214 can guide the fixed seat 24, thereby improving the stability of the fixed seat 24 during movement. In other alternative embodiments, the cross-section of the guide rod 214 can be circular, and a linear sliding bearing can be provided between the guide rod 214 and the fixed seat 24 to reduce the friction when the fixed seat 24 moves and improve the smoothness of the movement. In this embodiment, the lifting drive motor 23 is a servo motor. A lifting drive motor mounting base 213 is provided at the bottom of the lower horizontal frame 211 of the connecting frame 21. The lifting drive motor 23 is mounted on the lifting drive motor mounting base 213. The output shaft of the lifting drive motor 23 is connected to the lower end of the lead screw 22. The lifting drive motor 23 drives the lead screw 22 to rotate. The rotation of the lead screw 22 drives the fixed seat 24 screwed on the lead screw 22 to move, thereby driving the electric saw 27 to rise and fall.

[0044] Further, see Figure 4 The fixed base 24 has an installation groove 241, and one end of the outer sleeve 261 is rotatably connected to the installation groove 241 of the fixed base 24. The rotating mechanism includes a rotary drive motor 251, a drive gear 252, and a driven gear 253. The rotary drive motor 251 is located on one side of the fixed base 24. The drive gear 252 is fixedly connected to the output shaft of the rotary drive motor 251. The driven gear 253 is rotatably connected to the fixed base 24, and the driven gear 253 is connected to the outer sleeve 261 through a transmission shaft. The drive gear 252 and the driven gear 253 mesh with each other.

[0045] Specifically, the width of the mounting groove 241 on the fixed base 24 matches the width of the outer sleeve 261. The end of the outer sleeve 261 is positioned within the mounting groove 241 of the fixed base 24. A drive shaft is mounted at the end of the outer sleeve 261, with both ends rotatably connected to the fixed base 24. One end of the drive shaft extends through a side wall of the fixed base 24 and is fixedly connected to the driven gear 253. The rotary drive motor 251 drives the driving gear 252 to rotate, which in turn drives the driven gear 253 meshing with it. The driven gear 253 then drives the outer sleeve 261 to rotate via the drive shaft, ultimately achieving the adjustment of the angle of the chainsaw 27. In this embodiment, the rotary drive motor 251 is also a servo motor. A rotary drive motor mounting base 242 is provided on one side of the fixed base 24, and the rotary drive motor 251 is mounted on the rotary drive motor mounting base 242.

[0046] Further, see Figure 5In this embodiment, the telescopic arm drive mechanism is an electric push rod 263. The cylinder of the electric push rod 263 is fixedly connected to the bottom of the outer sleeve 261, and the front end of the telescopic rod of the electric push rod 263 is fixedly connected to the bottom of the telescopic plate 262. Specifically, the bottom of the telescopic plate 262 is provided with an ear plate 2622, and the front end of the telescopic rod of the electric push rod 263 is fixedly connected to the ear plate 2622. The extension and retraction of the telescopic rod of the electric push rod 263 causes the telescopic plate 262 to extend or retract into the outer sleeve 261, thereby causing the electric saw 27 provided at the front end of the telescopic plate 262 to move horizontally away from or towards the body 11 of the drone 1. In this embodiment, the outer tube 261 is a rectangular tube, and the telescopic plate 262 is a rectangular plate that matches the outer tube 261. Positioning grooves 2611 are respectively provided on both sides of the outer tube 261, extending along the length of the outer tube 261. Positioning sliders 2621 are correspondingly provided on both sides of the telescopic plate 262, and each positioning slider 2621 is slidably connected to its corresponding positioning groove 2611. By providing positioning sliders 2621 on the telescopic plate 262 and positioning grooves 2611 on the outer tube 261, when the telescopic plate 262 moves within the outer tube 261, the positioning sliders 2621 on the telescopic plate 262 will move along the positioning grooves 2611 on the outer tube 261, thereby improving the stability of the telescopic plate 262 during movement.

[0047] Furthermore, a camera 28 for real-time monitoring is installed on the outer tube 261 of the telescopic arm 26. By installing the camera 28 on the telescopic arm 26, the camera 28 can monitor the pruning process in real time, thereby enabling the chainsaw 27 to cut and prune tree obstacles more accurately.

[0048] Furthermore, a transparent protective cover 5 is also provided on the outer sleeve 261 of the telescopic arm 26, which covers the outside of the camera 28. Specifically, see... Figure 8 and Figure 9The protective cover 5 has a rectangular structure with an open bottom. Auxiliary plates 52 are fixed to both sides of the outer wall of the protective cover 5. Sliding holes 521 are provided on the auxiliary plates 52. The outer sleeve 261 is provided with two sliding rods 53. The distance between the two sliding rods 53 matches the distance between the sliding holes 521 on the two auxiliary plates 52. The sliding holes 521 on the two auxiliary plates 52 of the protective cover 5 are fitted onto the two sliding rods 53. External threads are machined on the sliding rods 53, and adjusting rings 54 are screwed onto the sliding rods 53. By turning the adjusting rings 54, the auxiliary plates 52 can be locked and fixed, thereby installing and fixing the protective cover 5 onto the outer sleeve 261. The protective cover 5 is specifically a glass cover. A handle 51 is fixedly connected to the top of the protective cover 5. The handle 51 has a "U"-shaped structure, which facilitates the removal and placement of the protective cover 5. It is understood that the protective cover 5 can also be made of polycarbonate sheet or acrylic sheet. By covering the camera 28 with a transparent protective cover 5, the camera 28 can be protected by the protective cover 5, thereby preventing debris from splashing onto the camera lens during tree trimming and causing damage to the lens, thus improving the service life of the camera 28. In this embodiment, a rubber pad 55 is also fixedly connected to the lower surface of the adjusting ring 54. The diameter of the rubber pad 55 is larger than the diameter of the adjusting ring 54. The rubber pad 55 can increase the friction between the lower surface of the adjusting ring 54 and the auxiliary plate 52, so that the adjusting ring 54 can be firmly abutted against the auxiliary plate 52 with the help of the rubber pad 55.

[0049] Further, see Figure 6 and Figure 7The mounting assembly 3 includes a threaded rod 31, an adjusting plate 32, and a connecting frame 34. A limiting ring 33 is fixedly provided at the bottom of the body 11 of the drone 1, and the upper end of the threaded rod 31 is rotatably connected to the limiting ring 33. The adjusting plate 32 is an isosceles trapezoid, with its center threadedly connected to the threaded rod 31. Two symmetrical connecting grooves 321 extending along the slopes are respectively provided on the two inclined sides of the adjusting plate 32, and a connecting frame 34 is slidably connected to each of the connecting grooves 321. Two limiting rods 35 are vertically arranged at the bottom of the body 11 of the drone 1, and the two sides of the adjusting plate 32 are slidably connected to the two limiting rods 35. The connecting frame 34 has a "T"-shaped structure and includes a connecting plate 342. A sliding plate 341 is vertically connected to the middle of the connecting plate 342, and one end of the sliding plate 341 away from the connecting plate 342 is slidably connected to the connecting groove 321. A plug 343 is fixed at each of the two ends of the connecting plate 342, and the plug 343 is located on the side of the connecting plate 342 facing the adjusting plate 32. A slot 2121 matching the plug 343 is opened on the outer side of each of the two vertical frames 212 of the connecting frame 21. By rotating the threaded rod 31, the adjusting plate 32 is moved, which in turn moves the two connecting frames 34 towards each other or away, so that the plug 343 can be inserted into or removed from the slot 2121, thereby fixing or disassembling the connecting frame 21.

[0050] Specifically, the adjusting plate 32 with an isosceles trapezoid structure is arranged upside down, that is, the longer bottom side of the adjusting plate 32 faces upward and the shorter bottom side of the adjusting plate 32 faces downward. The cross-section of the connecting groove 321 on the inclined waist side of the adjusting plate 32 has a "convex" shape structure. Correspondingly, one end of the connecting plate 342 of the connecting frame 34 is provided with a T-shaped connecting head matching the connecting groove 321, and the connecting plate 342 is slidably connected in the connecting groove 321 of the adjusting plate 32 through the T-shaped connecting head at its end. Through the above settings, the connecting frame 34 can slide along the connecting groove 321 and will not be disengaged from the connecting groove 321. A central threaded hole matching the threaded rod 31 is provided at the center of the adjusting plate 32, and the central threaded hole vertically penetrates the upper and lower ends of the adjusting plate 32. The adjusting plate 32 is threadedly connected to the threaded rod 31 through the central threaded hole. One limiting plate 322 is symmetrically arranged on each side of the adjusting plate 32. The limiting plates 322 on both sides of the adjusting plate 32 can be fixedly connected to the adjusting plate 32 by welding or screw connection. The two limiting plates 322 are symmetrically arranged relative to the central threaded hole, and limiting holes are provided on the limiting plates 322. The limiting plates 322 are slidably connected to the limiting rods 35 through the limiting holes. A rotating head for conveniently screwing and rotating the threaded rod 31 is further provided at the lower end of the threaded rod 31, and a knurled pattern for increasing friction is provided on the rotating head. The connecting plate 342 and the sliding plate 341 of the connecting frame 34 can be an integral structure. Among them, a reinforcing rib 344 is further provided between the connecting plate 342 and the sliding plate 341 to enhance the connection strength between the connecting plate 342 and the sliding plate 341. To facilitate the installation of the connecting frame 21 of the trimming component 2 and the installation component 3, a partition plate 215 is further provided on the upper cross frame 211 of the connecting frame 21. An auxiliary rod 216 in an "L" shape is fixedly provided at the bottom of the fuselage 11 of the drone 1. An auxiliary hanging hole matching the cross-section of the auxiliary rod 216 is provided on the partition plate 215, and the connecting frame 21 is hung on the auxiliary rod 216 through the partition plate 215. When installing the connecting frame 21, first sleeve the partition plate 215 on the connecting frame 21 onto the auxiliary rod 216, so as to temporarily support and limit the connecting frame 21 and facilitate the next installation operation.

[0051] Furthermore, the outer wall of the limiting ring 33 is provided with a threaded hole, and a pressure rod 36 is screwed into the threaded hole. One end of the pressure rod 36 abuts against the upper end of the threaded rod 31. The threaded rod 31 can be locked and fixed by screwing the pressure rod 36. In a specific implementation, a cylindrical rotating column can be provided at the upper end of the threaded rod 31. The diameter of the rotating column is larger than the diameter of the threaded rod 31. The bottom of the limiting ring 33 is provided with a cylindrical rotating groove that matches the rotating column. The rotating column is rotatably connected in the rotating groove. A circular ring plate is fitted on the threaded rod 31. The through hole in the center of the circular ring plate is larger than the diameter of the threaded rod 31 and smaller than the diameter of the rotating column. The circular ring plate is fixedly connected to the bottom of the limiting ring 33 by welding or screw connection to limit the rotating column and prevent the rotating column from coming out of the limiting ring 33. In this embodiment, the pressure rod 36 is a hexagonal head bolt, which is screwed into the threaded hole on the limiting ring 33. After the trimming component 2 is fixed and secure, the rod end of the hexagonal head bolt can be pressed against the rotating column in the limiting ring 33 by tightening the hexagonal head bolt with a wrench, thereby locking and fixing the threaded rod 31 and preventing the trimming component 2 from shaking due to the instability of the threaded rod 31.

[0052] The method of using this drone-based tree trimming device is as follows:

[0053] When installing the trimming assembly 2, first move the connecting frame 21 and place the partition 215 on the connecting frame 21 onto the auxiliary rod 216. After the partition 215 is placed on the auxiliary rod 216 and the slot 2121 on the connecting frame 21 is aligned with the insert 343 on the adjusting plate 32, rotate the threaded rod 31 to drive the adjusting plate 32 to move upward. When the adjusting plate 32 moves, it will drive the connecting frame 34 with the help of the connecting groove 321, so that the two connecting frames 34 move towards each other at the same time. After the connecting frame 34 drives the insert 343 to insert into the slot 2121, rotate the pressure rod 36 to abut against the threaded rod 31 to complete the installation of the trimming assembly 2. When it is necessary to disassemble the trimming assembly 2, first rotate the pressure rod 36 to separate it from the threaded rod 31, release the lock on the threaded rod 31, and then rotate the threaded rod 31 in the opposite direction. The threaded rod 31 drives the adjusting plate 32 to move downward. The adjusting plate 32 drives the two connecting brackets 34 to move away from each other at the same time. When the connecting brackets 34 drive the insert block 343 to separate from the slot 2121 on the connecting frame 21, the disassembly of the trimming assembly 2 can be completed.

[0054] When pruning tree obstacles, the operator first controls the drone 1 to fly to the tree obstacle to be pruned. After the drone 1 flies to the tree obstacle, the electric push rod 263 is activated to drive the telescopic plate 262, causing the telescopic plate 262 to move away from the outer sleeve 261. The telescopic plate 262 drives the electric saw 27, and at the same time the motor is started, so that the electric saw 27 can prune the tree obstacle. The angle and height of the electric saw 27 can be adjusted, so that the electric saw 27 can prune tree obstacles at different angles. The specific steps are as follows: Start the lifting drive motor 23 to drive the lead screw 22 to rotate. The lead screw 22 drives the fixed seat 24, causing the fixed seat 24 to rise and fall. The fixed seat 24 drives the outer sleeve 261 and the telescopic plate 262 to move. The telescopic plate 262 drives the electric saw 27, thereby adjusting the height of the electric saw 27. Start the rotation drive motor 251 to drive the drive gear 252 to rotate. The drive gear 252 drives the driven gear 253 to rotate. The driven gear 253 drives the outer sleeve 261 to rotate vertically along the fixed seat 24. The outer sleeve 261 drives the telescopic plate 262 and the electric saw 27, thereby adjusting the height and angle of the electric saw 27 relative to the drone 1. After trimming is completed, start the lifting drive motor 23, the rotation drive motor 251, and the electric push rod 263 to return the electric saw 27 to its original position.

[0055] In summary, the tree trimming device based on a drone provided by this utility model can automatically adjust the chainsaw to trim trees next to power lines in different postures. The function of automatically adjusting the chainsaw posture can accurately adjust the angle and position of the saw blade according to the location and shape of the trees and the specific conditions of the power lines, thereby ensuring the accuracy of the trimming.
