DETAILED DESCRIPTION

[0029] The specific embodiments of the present application will be further described in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0030] The "target" referred to in the examples refers to a tree barrier that needs to be pruned, and the tree barrier includes tree branches.

[0031] As Figures 1 to 7As shown, the obstacle removing unmanned aerial vehicle of the present application comprises an unmanned aerial vehicle assembly 1, a cutting device 2 and a power source, the power source comprises a first driving device, a second driving device and a third driving device, the cutting device 2 comprises a lower clamping component 21, an upper clamping support 23 and a cutting tool 22, the lower clamping component 21 comprises a lower clamping support 212, the lower clamping support 212 and the upper clamping support 23 are rotationally connected, the third driving device drives the upper clamping support 23 to rotate to clamp the target, the lower clamping support 212 and the cutting tool 22 are rotationally connected, the second driving device drives the cutting tool 22 to rotate to cut the target, the unmanned aerial vehicle assembly 1 and the lower clamping component 21 are rotationally connected, and the first driving device drives the lower clamping component 21 to rotate to adjust the working position of the cutting device 2.

[0032] Based on the above technical solution, the unmanned aerial vehicle assembly 1 comprises an unmanned aerial vehicle body 11, and the unmanned aerial vehicle body 11 at least comprises a general unmanned aerial vehicle with general functions on the market. Such an unmanned aerial vehicle is an unmanned aerial vehicle device capable of independent flight, independent power supply, navigation, wireless control, image recognition, image transmission and other conventional functions in the field. The cutting tool 22 is a device that can at least realize the function of cutting the target. Specifically, it can be a device for cutting, including a chain saw, a wheel cutter, an electric control clamp, etc. The power source is a device for driving two rotationally connected components to rotate on the structure, and all have the functions of braking and locking. When the power source rotates the two components to a specified relative position, the power source can brake and lock the relative position of the two components. The power source can all be motors. The power source comprises a first driving device, a second driving device, …, an Nth driving device, where the serial number is used to distinguish the driving devices arranged between different rotationally connected components. When components A and B are in the following state: A and B are rotationally connected, the power source drives A or B to rotate. The connection relationship of the power source can be: the power source and A are fixedly connected, and the power source and B are transmissionally connected to rotate B. The power source and B are fixedly connected, and the power source and A are transmissionally connected to rotate A.

[0033] The second driving device drives the cutting tool 22 to rotate to reduce the included angle between the lower clamping support 212 and the cutting tool 22. When the included angle between the lower clamping support 212 and the cutting tool 22 is reduced to a certain angle, the target is cut. The third driving device drives the upper clamping support 23 to rotate to reduce the included angle between the lower clamping support 212 and the upper clamping support 23. When the included angle between the lower clamping support 212 and the upper clamping support 23 is reduced to a certain angle, the target is clamped. Clamping the target before cutting can improve the stability and safety of the cutting operation.

[0034] Further, the lower clamping support 212, the upper clamping support 23 and the cutting tool 22 are arranged staggered.

[0035] The staggered arrangement of the lower clamping support 212, the upper clamping support 23 and the cutting tool 22 allows the upper clamping support 23 and the cutting tool 22 to rotate 360°, making the clamping and cutting actions more flexible, preventing the lower clamping support 212, the upper clamping support 23 and the cutting tool 22 from touching each other and being damaged, and facilitating the hiding and storage of the lower clamping support 212, the upper clamping support 23 and the cutting tool 22 in a non-working state by minimizing the included angle between the lower clamping support 212, the upper clamping support 23 and the cutting tool 22 and making the profile shapes of the three in the axial direction of the rotating shaft overlap as much as possible.

[0036] Further, the lower clamping member 21 further comprises a horizontal rotating frame 211, the unmanned aerial vehicle assembly 1 and the horizontal rotating frame 211 are rotationally connected, the first driving device drives the horizontal rotating frame 211 to rotate to adjust the working position of the cutting device 2, the power source further comprises a fourth driving device, the horizontal rotating frame 211 and the lower clamping support 212 are rotationally connected, and the fourth driving device drives the lower clamping support 212 to rotate to adjust the working position of the cutting device 2, the rotating surfaces of the horizontal rotating frame 211 and the lower clamping support 212 and the rotating surfaces of the horizontal rotating frame 211 and the unmanned aerial vehicle assembly 1 are arranged at an included angle greater than 0.

[0037] The horizontal rotating frame 211 allows the cutting device 2 to rotate in a direction perpendicular to the rotating plane of the unmanned aerial vehicle assembly 1 and the cutting device 2, thereby expanding the working position of the cutting device 2 and expanding the dimension of the rotating position of the cutting device 2. Taking the XYZ coordinate system as an example (the included angle between the X axis, the Y axis and the Z axis is greater than 0, but not necessarily 90°), the rotating shaft of the rotationally connected unmanned aerial vehicle assembly 1 and horizontal rotating frame 211 is set as the Z axis, the first driving device drives the horizontal rotating frame 211 to rotate to adjust the working position of the cutting device 2 only in the position of rotating around the Z axis, and because the rotating surfaces of the horizontal rotating frame 211 and the lower clamping support 212 and the rotating surfaces of the horizontal rotating frame 211 and the unmanned aerial vehicle assembly 1 are arranged at an included angle greater than 0, the fourth driving device drives the lower clamping support 212 to rotate to adjust the working position of the cutting device 2 in the position of rotating around the X axis or the Y axis.

[0038] Further, the lower clamping support 212 and / or the upper clamping support 23 is fixedly provided with a plurality of clamping protrusions 24 to enhance the stability of the lower clamping support 212 and the upper clamping support 23 clamping the target. The upper clamping support 23 is rotatably connected to the lower clamping support 212 at one end, which is the upper clamping start end. The upper clamping support 23 is rotatably connected to the lower clamping support 212 at the other end, which is the upper clamping end. The protrusion height of the clamping protrusions 24 and the interval distance between the clamping protrusions 24 increase from the upper clamping start end to the upper clamping end.

[0039] When the clamping action is performed, the clamping protrusions 24 are inserted into and embedded in the target to increase the stability of clamping and prevent unstable clamping. The clamping protrusions 24 are provided with sharp parts to better embed in the target. The upper end surface and the lower end surface of the lower clamping support 212 and the upper clamping support 23 can be provided with clamping protrusions 24 to enable the upper clamping support 23 to perform counterclockwise clamping and clockwise clamping. The lower clamping support 212 and the upper clamping support 23 can be provided with a plurality of clamping protrusions 24 along the length direction to increase the area that can be stably clamped.

[0040] When the target is closer to the clamping start end for clamping, the target has a smaller contour, and the clamping protrusions 24 with a smaller protrusion height and a smaller interval distance are more easily embedded in the target, making the clamping more stable. When the target is closer to the clamping end for clamping, the target has a larger contour, and the clamping protrusions 24 with a larger protrusion height and a larger interval distance are more easily embedded in the target, making the clamping more stable.

[0041] Further, the cutting tool 22 includes a guide plate 222 and a sawtooth 221. The lower clamping support 212 is rotatably connected to the guide plate 222. The second driving device drives the guide plate 222 to rotate to approach the target. The sawtooth 221 is movably arranged around the edge of the guide plate 222. The power source further includes a fifth driving device. The fifth driving device drives the sawtooth 221 to rotate around the guide plate 222 to cut the target.

[0042] The cutting tool 22 can be a chain saw blade.

[0043] Further, the lower clamping support 212 is provided with a plurality of cutting tools 22. The plurality of cutting tools 22 are respectively arranged on both sides of the upper clamping support 23. Each second driving device independently drives one cutting tool 22.

[0044] The plurality of cutting tools 22 are respectively driven by independent second driving devices and arranged on both sides of the upper clamping support 23 to facilitate cutting of the target on either side individually; since after cutting, the cut branches are likely to hit the UAV itself, other objects or people, the cutting device 2 will only cut the branches close to the side of the trunk to ensure that no branches will fall immediately after cutting, and then the cut and clamped branches on the cutting device 2 are moved to a suitable position, and the branches are released; the plurality of cutting tools 22 arranged on both sides of the upper clamping support 23 are to improve the flexibility of cutting work, without considering the left and right positions of the UAV relative to the tree before clamping.

[0045] Further, the UAV assembly 1 is provided with a receiving groove 13, the receiving groove 13 and the cutting device 2 are matched in shape, and the first driving device drives the cutting device 2 to rotate to receive the cutting device 2 into the receiving groove 13 or rotate out of the receiving groove 13 and adjust the working position of the cutting device 2.

[0046] The receiving groove 13 is used to receive the cutting device 2 to improve the compactness and safety of the UAV in the non-working state.

[0047] Further, the rotation connection center of the UAV assembly 1 and the cutting device 2 is arranged on the receiving groove 13.

[0048] The rotation connection center arranged on the receiving groove 13 can further improve the compactness of the UAV structure, avoiding the protrusion of parts outside the UAV assembly 1 in the receiving state.

[0049] Further, the cutting device 2 is in an overall arc structure in the receiving state, and further, the lower clamping part 21, the upper clamping support 23 and the cutting tool 22 are all arc structures.

[0050] The arc structure can reduce the complexity of the UAV assembly 1 designed to receive the cutting device 2, and the longer the cutting device 2 is, the more serious the problem is, and it will reduce the compactness of the UAV assembly 1, making it bloated; when the cutting device 2 is in an arc structure, the outer side of the UAV assembly 1 designed as a ring-shaped body to reduce the volume and increase the structural compactness can be provided with a receiving groove 13 matched with the shape of the cutting device 2 along its outer shape; the arc structure of the cutting device 2 can also increase the contact area of the upper clamping support 23 and the lower clamping support 212 with the target during clamping to increase the stability of clamping and cutting work.

[0051] Further, the unmanned aerial vehicle assembly 1 further comprises an unmanned aerial vehicle body 11 and a rotating bracket 12, the rotating bracket 12 and the cutting device 2 are rotationally connected, the first driving device is used for driving the cutting device 2 to rotate, the power source further comprises a sixth driving device, the rotating bracket 12 is covered outside the unmanned aerial vehicle body 11, the unmanned aerial vehicle body 11 and the rotating bracket 12 are rotationally connected, and the sixth driving device rotates the rotating bracket 12 to adjust the working position of the cutting device 2.

[0052] The rotating bracket 12 is used for expanding the adjustable working position of the cutting device 2; the rotationally connected position of the rotating bracket 12 and the cutting device 2 is located close to the outside of the unmanned aerial vehicle assembly 1, so that the cutting range of the cutting device 2 extends outwardly with the rotationally connected position of the rotating bracket 12 and the cutting device 2 as the center, and has certain limitations; the rotationally connected position of the rotating bracket 12 and the cutting device 2 and the unmanned aerial vehicle body 11 are changed by the rotationally connected position of the unmanned aerial vehicle body 11 and the rotating bracket 12, so that the working position of the cutting device 2 can reach more places to cover more positions in the working range, and the function of expanding the adjustable working position of the cutting device 2 to expand the working range of the cutting device 2 is realized.
