[0038] See Figures 1 to 3 The remote sensing mapping device provided in this embodiment includes a drone 100, an adjustment mechanism 200, and a mapping instrument 300.

[0039] The drone 100 has legs 110, and a mounting part 120 is located on the bottom of the drone 100, on one side of the legs 110. An adjustment mechanism 200 is located on the mounting part 120, and the adjustment mechanism 200 includes a height adjustment component and a tilting component, with the tilting component's rotation axis extending horizontally. The surveying instrument 300 is connected to the height adjustment component and the tilting component via a transmission connection. The highest point of the surveying instrument 300's bottom is above the lowest point of the legs 110, and the lowest point of the surveying instrument 300's bottom is below the lowest point of the legs 110.

[0040] In this embodiment, the mapping instrument 300 is connected to the adjustment mechanism 200 and is mounted on the mounting part 120 at the bottom of the UAV 100. The UAV 100 can carry the adjustment mechanism 200 and the mapping instrument 300 to the target area for mapping.

[0041] During the surveying process, the height adjustment component in the adjustment mechanism 200 moves the surveying instrument 300 downward, so that the surveying instrument 300 is located below the support leg 110, thus preventing the support leg 110 from blocking the lens of the surveying instrument 300. The flipping component can also be used to rotate the surveying instrument 300 vertically so that the surveying instrument 300 can achieve the best shooting angle.

[0042] After the surveying is completed, the height adjustment component in the adjustment mechanism 200 is driven again to move the surveying instrument 300 upward, so that the surveying instrument 300 is retracted above the support leg 110, thus preventing the surveying instrument 300 from colliding with the ground during landing or takeoff, thereby protecting the surveying instrument 300.

[0043] In this embodiment, the driving component is connected to the surveying instrument 300, thereby realizing the adjustment of the height and shooting angle of the surveying instrument 300, avoiding the problem of the support leg 110 obstructing the lens field of view, reducing the error of surveying data, and improving the flexibility and accuracy of surveying work.

[0046] Specifically, in this embodiment, the first driving component 220 is an electric cylinder. The top end of the electric cylinder is inserted into the insertion hole 211 and electrically connected to the drone 100. The moving end of the electric cylinder is located at the bottom end of the electric cylinder so that the moving end of the electric cylinder can drive the surveying instrument 300 to move vertically.

[0047] See Figure 6In this embodiment, the adjustment mechanism 200 further includes a first connector 230. One end of the first connector 230 is detachably connected to the driving end of the first drive member 220, and the other end of the first connector 230 extends toward the drone 100. The vertical length of the first connector 230 is less than the driving distance of the first drive member 220. A flipping assembly is disposed at the end of the first connector 230 near the drone 100, and the surveying instrument 300 is connected to the driving end of the flipping assembly.

[0048] Specifically, in this embodiment, the first connector 230 has parallel mounting plates at both ends, which are connected by a connecting plate, and the two mounting plates are respectively located on both sides of the connecting plate.

[0049] In this embodiment, both mounting plates are provided with through holes, and the moving end of the first driving member 220 is provided with bolts. The moving end of the first driving member 220 is connected to the driving end of the first driving member 220 by inserting the bolts into the through holes.

[0050] Furthermore, in this embodiment, the length of the connecting plate is less than the driving stroke of the first driving member 220, so as to ensure that the first driving member 220 can drive the surveying instrument 300 to move down to below the support leg 110.

[0051] See Figures 7 to 9 In this embodiment, the flipping assembly includes a second connector 250, a mounting member 240, and a second drive member 260. One end of the second connector 250 is detachably connected to the first connector 230. The mounting member 240 is rotatably connected to the other end of the second connector 250, and the surveying instrument 300 is mounted on the mounting member 240. The second drive member 260 is mounted on the second connector 250 and is drively connected to the mounting member 240.

[0052] Specifically, in this embodiment, a sleeve 231 is provided at the through hole of the moving end of the first driving member 220 away from the first connecting member 230, and the sleeve 231 can be easily connected to the second connecting member 250.

[0053] The second drive component 260 is disposed on the second connector 250. The drive end of the second drive component 260 is connected to the mounting component 240 to drive the mounting component 240 and the surveying instrument 300 on the mounting component 240 to perform a flipping action.

[0054] In this embodiment, the end of the second connector 250 away from the UAV 100 has a plurality of spaced-apart connecting portions 241. Each connecting portion 241 has a shaft hole, and the shaft holes on the plurality of connecting portions 241 are positioned opposite each other. The mounting member 240 has a rotating shaft, which is inserted into the shaft hole. The driving end of the second drive member 260 is connected to the rotating shaft. The rotating shaft on the mounting member 240 is inserted into the shaft hole on the connecting portion 241, thereby achieving a rotatable connection between the mounting member 240 and the second connector 250. In this structure, the rotating shaft at the driving end of the second drive member 260 is coaxially arranged with the rotating shaft on the mounting member 240, so that the second drive member 260 can drive the mounting member 240 and the surveying instrument 300 to perform a flipping action.

[0055] In this embodiment, there are two connecting parts 241. The mounting member 240 is a frame with two rotating shafts, each located on one of the two parallel outer side walls of the frame. The surveying instrument 300 is housed within the frame.

[0056] Specifically, in this embodiment, the two connecting parts 241 are spaced apart and respectively located on both sides of the mounting member 240. Correspondingly, the two rotating shafts of the mounting member 240 are also located on the outside of the mounting member 240 to realize the corresponding insertion with the shaft holes on the two connecting parts 241.

[0057] In this embodiment, the frame sidewall is provided with screw holes, and the surveyor 300 is locked to the screw holes with screws, thereby connecting the surveyor 300 and the mounting component 240. In this embodiment, the shafts on both sides of the mounting component 240 have locking holes at their centers. The cross-sectional shape of the shaft of the second drive component 260 is adapted to these locking holes, so that the shaft of the second drive component 260 can engage with the shafts on both sides of the mounting component 240, thereby achieving a transmission connection between the second drive component 260 and the mounting component 240.

[0058] In this embodiment, the mounting part 120 has a plurality of sliders 121 spaced apart. The mounting base 210 is provided with a plurality of sliding grooves 212, which are connected to the plurality of sliders 121 in a one-to-one correspondence so that the mounting base 210 and the mounting part 120 are engaged. After the mounting base 210 and the mounting part 120 are engaged, they are locked with screws.

[0059] In this embodiment, the mounting base 210 is positioned by the cooperation of the slider 121 and the slide groove 212. The mounting base 210 is connected to the drone 100 by the sliding cooperation of the slider 121 and the slide groove 212. Then, the mounting base 210 is locked on the mounting part 120 by screws, so as to realize the detachable connection of the mounting base 210 on the drone 100.

[0060] In this embodiment, there are two sliders 121. The two sliders 121 are spaced apart and arranged in parallel, forming a slide rail between them. There are two slide grooves 212, which are respectively provided on both sides of the mounting base 210. The mounting base 210 is located in the slide rail so that the sliders 121 are inserted into the slide grooves 212.

[0061] Please refer to it again. Figure 3 Specifically, in this embodiment, two L-shaped sliders 121 are spaced apart and arranged in parallel to form a slide. The two L-shaped sliders 121 are inserted into the slide groove 212 from both sides of the mounting base 210, so that the two sliders 121 can share the weight borne by the mounting base 210 and can achieve sliding cooperation between the sliders 121 and the mounting base 210.

[0062] In this embodiment, the mounting base 210 is provided with a plurality of locking screws. After the mounting base 210 is connected to the slider 121 and reaches the preset position, the position of the mounting base 210 can be fixed at the preset position by tightening the locking screws.

One end of the first drive member 220, which is located in the insertion hole 211, is electrically connected to the drone 100, and the fixing member 221 extends horizontally and is connected to the mounting base 210 by screws.

[0064] Specifically, in this embodiment, the fixing member 221 is located in the middle part of the first driving member 220. The fixing member 221 is provided with a plurality of through holes for accommodating bolts at circumferential intervals, so that the fixing seat can be detachably connected to the mounting seat 210 by means of bolt connection.

[0065] In this embodiment, there are multiple legs 110. The multiple legs 110 are arranged circumferentially along the mounting portion 120.

[0066] Specifically, in this embodiment, there are five legs 110. The five legs 110 are spaced apart and evenly arranged on the bottom surface of the drone 100 along the circumference of the mounting part 120 so that the drone 100 can maintain balance when flying and parking.
