The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] A laser felling device based on an air-based platform, such as Figure 1-Figure 5 As shown, it includes an air-based platform, a scanning module 2 for identifying various parts of a felled object is arranged on the air-based platform, a support mechanism 3 for supporting the felled object is arranged on the air-based platform, a driver is arranged on the output part of the driver, a support mechanism 5 is arranged on the support mechanism 5, a laser feller 6 is arranged on the support mechanism 5, the driver is used to drive the support mechanism 5 to move, and a balancing mechanism 7 for counterweight is arranged on the air-based platform;

[0027] Specifically, the air-based platform is a drone 1, a scanning module 2 for identifying various parts of a felled object is arranged in the middle of the drone 1, a leg mechanism 3 for supporting the drone 1 is arranged on the side of the drone 1, a driver is arranged on the lower side of the drone 1, the driver is an electric slide rail 4, a support mechanism 5 is arranged on the output part of the electric slide rail 4, a laser feller 6 is arranged on the support mechanism 5, the electric slide rail 4 is used to drive the support mechanism 5 to move, and a balancing mechanism 7 for counterweight is arranged on the side of the drone 1 close to the electric slide rail 4;

[0028] When it is necessary to cut down trees, the operator can start the UAV 1 and make the UAV 1 fly to the trees that need to be cut down, and then control the scanning module 2 through the ground control station to scan the specific shape of the tree and determine the position to be cut down. After determining, the UAV 1 is flown to a position convenient for cutting and hovered there. After hovering at a good position, the operator can control the supporting mechanism 5 to accurately adjust the angle of the laser cutter 6, and can operate the electric slide 4 to accurately adjust the position of the laser cutter 6. The specific operation of adjusting the laser cutter 6 on the electric slide 4 is that the operator starts the electric slide 4 through the ground control station, and the electric slide 4 drives the supporting mechanism 5 to move, and the supporting mechanism 5 drives the laser cutter 6 to move. When the angle of the laser cutter 6 is also accurately adjusted and the position is also accurately adjusted, the operator can start the laser cutter 6 through the ground control station, and the laser cutter 6 cuts the tree. When the electric slide 4 drives the supporting mechanism 5 to move and adjust the position of the laser cutter 6, the balancing mechanism 7 can make the UAV 1 in a balanced state.

[0029] like Figure 4-Figure 5As shown, the balancing mechanism 7 includes a guide rail 71 arranged on the air-based platform, a counterweight 73 slidably connected to the guide rail 71, and two groups of pulling components 72 for pulling the counterweight 73 to move. The pulling component 72 includes a bracket 721 fixedly connected to the guide rail 71, a winding wheel 722 arranged on the bracket 721, and a pull rope 723. One end of the pull rope 723 is connected to the counterweight 73 and the other end is connected to the supporting mechanism 5 by passing through the winding wheel 722. When the supporting mechanism 5 moves, the counterweight 73 is moved in the opposite direction of the supporting mechanism 5 through the pulling component 72; the air-based platform is the drone 1; the driver is the electric slide rail 4.

[0030] Specifically, a guide rail 71 is provided on one side of the air-based platform close to the electric slide rail 4, and a counterweight 73 is slidably connected to the guide rail 71. The balancing mechanism 7 also includes two groups of pulling components 72 for pulling the counterweight 73 to move. The two groups of pulling components 72 are symmetrically arranged. The pulling component 72 includes a bracket 721 fixedly connected to the guide rail 71, a pull rope 723, and a winding wheel 722 arranged on the bracket 721. One end of the pull rope 723 is connected to the counterweight 73 and the other end is connected to the support mechanism 5 by passing through the winding wheel 722. When the support mechanism 5 moves, the counterweight 73 is moved in the opposite direction of the support mechanism 5 through the pulling component 72.

[0031] When the electric slide 4 drives the supporting mechanism 5 to move and adjust the position of the laser cutter 6, if the electric slide 4 drives the supporting mechanism 5 and the laser cutter 6 to move to the left, the supporting mechanism 5 will loosen the pull rope 723 on the left and pull the pull rope 723 on the right. The pull rope 723 on the right pulls the counterweight 73 to move to the right. Therefore, when the supporting mechanism 5 and the laser cutter 6 move to the left side of the drone 1, the counterweight 73 will move to the right side of the drone 1. The weight of the counterweight 73 matches the weight of the supporting mechanism 5 and the laser cutter 6, so the balance of the drone 1 can be ensured, so that the drone 1 can stably hover in one place. On the contrary, when the electric slide 4 drives the supporting mechanism 5 and the laser cutter 6 to move to the right, the pull rope 723 on the left will pull the counterweight 73 to move to the left to achieve balance.

[0032] In summary, the device utilizes the laser cutter 6 and drone 1 technology to perform firebreak operations more quickly and efficiently. The laser cutter 6 based on the air-based platform has a higher operating speed and accuracy, and can quickly cut branches in the firebreak to reduce the risk of fire spread. At the same time, the device uses the drone 1 platform for operation, and the drone 1 has the advantage of flexibility and mobility. By carrying the laser cutter 6, the drone 1 can quickly cover a large area of ​​firebreaks and operate in high-risk areas for fire spread, reducing the risk exposure of personnel;

[0033] Secondly, the UAV 1 platform also has a remote control function, and the operation of the device can be monitored and adjusted in real time through the ground control station. The operator can adjust the parameters of the laser feller 6 according to the actual situation to adapt to different trees and terrain conditions, and improve the operation effect and safety;

[0034] In addition, the device is provided with a balancing mechanism 7. When the electric slide rail 4 drives the supporting mechanism 5 to move and adjust the position of the laser cutter 6, the counterweight block 73 will move in the opposite direction, thereby ensuring the balance of the drone 1 and placing the drone 1 in a stable hovering state.

[0035] The scanning module 2 includes a laser radar module, an infrared thermal imaging module and a high-resolution image processing module. The laser radar module is used to obtain the three-dimensional structural information of the cut object, the infrared thermal imaging module is used to obtain the thermal radiation of the cut object, and the high-resolution image processing module is used to obtain the shape, texture and color information of the cut object.

[0036] Among them, scanning module 2 mainly uses technologies such as laser radar module, infrared thermal imaging module, and high-resolution image processing module. The laser radar module obtains the three-dimensional structural information of trees by emitting laser beams and measuring their return time, which can provide high-precision distance measurement and point cloud data, and can effectively capture the shape and outline of trees; the high-resolution image processing module technology uses aerial photography or remote sensing images to obtain information such as the shape, texture and color of tree crowns and trunks. Through image processing algorithms, the characteristics of trees can be extracted and recognized and classified; the infrared thermal imaging module technology can detect the thermal radiation of trees, and identify parts such as tree crowns, trunks and branches based on the thermal differences between trees and the surrounding environment, which is very advantageous for tree recognition at night or in low light conditions.

[0037] like Figure 2 As shown, the support leg mechanism 3 includes four groups of support legs 31 and two groups of drive components 32, two groups of support legs 31 are arranged on one side of the drone 1, and the other two groups of support legs 31 are arranged on the other side of the drone 1, and one group of drive components 32 is arranged between the two groups of support legs 31 on the same side, the support mechanism 5 includes a support block 311 fixedly connected to the drone 1 and a rocker 312 rotatably connected to the support block 311, the drive component 32 includes a mounting seat 321 fixedly connected to the drone 1 and a dual-axis motor 322 connected to the mounting seat 321, the output shafts of the dual-axis motor 322 are fixedly connected to the first rotating shaft 323, and the first rotating shaft 323 is fixedly connected to the rocker 312.

[0038] After the UAV 1 takes off, the operator can control the dual-axis motor 322 through the ground control station. The dual-axis motor 322 starts to drive the first rotating shaft 323 to rotate. The rotation of the first rotating shaft 323 drives the swing arm 312 to rotate, so that the swing arm 312 rotates to be horizontal with the UAV 1. Therefore, after the support mechanism 5 adjusts the angle of the laser cutter 6, the laser cutter 6 is started, and the swing arm 312 will not block it. When the UAV 1 needs to land, the operator can start the dual-axis motor 322 again. The dual-axis motor 322 drives the first rotating shaft 323 to rotate. The rotation of the first rotating shaft 323 drives the swing arm 312 to be horizontal. Therefore, when the UAV 1 falls, the swing arm 312 props up the entire UAV 1, so that the UAV 1 lands smoothly.

[0039] like Figure 2 As shown, a buffer pad 33 is provided on the end of the swing rod 312 .

[0040] Among them, through the effect of the buffer pad 33, when the drone 1 lands, the buffer pad 33 contacts the bottom surface, and the buffer pad 33 can buffer a part of the inertia generated when the drone 1 falls, so that the drone 1 lands more smoothly.

[0041] like Figure 3 As shown, the support mechanism 5 includes a fixed seat 51 fixedly connected to the output member of the electric slide rail 4 and a first driving member arranged on the fixed seat 51, a rotating frame 53 is connected to the output shaft of the first driving member, a second driving member and a second rotating shaft 55 rotatably connected are arranged on the rotating frame 53, a laser cutter 6 is arranged between the second rotating shaft 55 and the output shaft of the second driving member, and the first driving member and the second driving member are a first motor 52 and a second motor 54 respectively.

[0042] When the operator needs to precisely adjust the angle of the laser cutter 6, the operator can control the first motor 52 through the ground control station. The first motor 52 drives the rotating frame 53 to rotate. The rotation of the rotating frame 53 drives the laser cutter 6 to rotate left and right. The operator can also control the second motor 54 through the ground control station. The second motor 54 starts and drives the laser cutter 6 to rotate up and down, thereby achieving precise adjustment of the angle of the laser cutter 6.
