Description

Technical Field

[0001] The invention relates to the technical field of tree barrier clearing devices, and in particular to a device for clearing high-altitude tree barriers and a working method thereof. Background Art

[0002] In the fields of forestry, gardening, and urban greening, the treatment of high-altitude tree obstacles has always been an important and thorny issue. Traditional treatment methods mainly rely on manual climbing or pruning with long-handled tools, which are not only inefficient but also have extremely high safety risks. With the rapid development of drone technology, using drones to carry tools for high-altitude operations has become a trend.

[0003] At present, some tree barrier clearing equipment based on drones have appeared on the market, such as a tree barrier clearing flying robot with a scissor-fork type hanging tool disclosed in CN112498719A, which includes a flying platform, a hanging mechanism connected to the bottom of the flying platform, and a tool system connected to the bottom of the hanging mechanism; the hanging mechanism includes a horizontally arranged I-shaped frame, a telescopic device hung under the I-shaped frame, and a lower connecting seat connected to the lower end of the telescopic device and docked with the tool system; the tool system is an array combination of M (M≥1) electric saw components arranged in a left-right geometric symmetry or mass symmetry manner; a decoupling device is provided between the hanging mechanism and the tool system to connect or separate the two; the device carries the pruning tool by the drone, and uses the mechanical arm to control the tool to prune the tree barrier; however, the device has the following shortcomings: first, the design of the pruning tool is relatively simple and it is difficult to adapt to the complex and changeable tree barrier forms; second, the control accuracy and flexibility of the mechanical arm need to be improved to ensure the accuracy and safety of pruning; third, the weight and volume of the entire device are large, which puts forward high requirements on the flight performance and load capacity of the drone.

[0004] In addition, there are some cutting devices based on the chain saw principle that are used in clearing tree obstacles at high altitudes. For example, CN109287308A discloses a flying branch pruning device, comprising a chain saw platform (1) towed by an unmanned aerial vehicle, the bottom of the chain saw platform (1) is provided with a translation support mechanism (2) capable of linearly moving relative to the chain saw platform (1) and a fixedly arranged chain saw mechanism (3), the translation support mechanism (2) is provided with a clamping mechanism (4) capable of clamping a tree trunk, and the clamping mechanism (4) is provided with a translation drive mechanism (5) capable of driving the chain saw platform (1) to move closer to or away from the clamping mechanism (4), the driving part of the translation drive mechanism (5) is fixedly arranged on the clamping mechanism (4), and the clamping mechanism (4) and the translation support mechanism (3) are connected to each other. The spacing between the mechanisms (2) is constant, and the translation drive mechanism (5) pulls or pushes the chain saw platform (1) toward or away from the clamping mechanism (4) by changing the positional relationship between the translation support mechanism (2) and the chain saw platform (1); the device uses a drone to carry a chain saw, and utilizes the high-speed rotation of the chain saw to cut tree obstacles; however, the device also exposes some problems in actual application: first, the driving and control methods of the chain saw are relatively complex, requiring a special control system and power source; second, the cutting efficiency and cutting quality of the chain saw are affected by many factors, such as the tension of the chain, the rotation speed, and the cutting angle; third, the vibration and noise generated by the chain saw during the cutting process are relatively large, which has a certain impact on the stability of the drone and the comfort of the operator.

[0005] In summary, the existing UAV-based tree obstacle clearing equipment still has many shortcomings in tool design, robotic arm control, device weight and volume, chain saw drive and control, cutting efficiency and cutting quality; therefore, it is necessary to improve and optimize the existing high-altitude tree obstacle clearing equipment to improve its work efficiency, safety and applicability.

[0044] In summary, the present invention provides a device for clearing high-altitude tree obstacles and a working method thereof, which realizes the clearing of high-altitude tree obstacles in different environments through the cooperation of the designed locking mechanism, tree obstacle clearing mechanism and control system; the present invention combines drone technology with the cutting function of an electric saw to realize the mechanized processing of high-altitude tree obstacles, which provides a new solution based on the traditional manual use of high-branch saws for tree obstacle clearing; through the integrated design of the locking mechanism, tree obstacle clearing mechanism and control system, the entire device can be stably mounted on the drone and can perform accurate tree obstacle cutting in the air. This integrated design concept is not common in previous tree obstacle clearing tools; it also uses hollow aluminum material to make the first support frame 4 and the connecting plate, which not only reduces the weight of the equipment, but also ensures sufficient strength and stability; the design of the locking mechanism drives the rotating arm 18 through the servo 12 to drive the intermediate connecting rod 17 and then push the locking rod 15 to lock the hook 16 ring firmly on the hook 16, This design not only achieves stable mounting of the equipment, but also facilitates quick disassembly when needed, reflecting a high degree of creativity; the tree obstacle clearing mechanism uses the support frame 4 as the supporting skeleton, and drives the saw blade 14 to rotate through the joint action of the pulley 8 and the gear. This design makes the cutting process more efficient and stable, while also reducing the difficulty and risk factor of operation; the introduction of the control system enables the working state of the entire equipment to be controlled in real time, including the start and stop of the drive motor 1, the start and stop of the locking mechanism, etc. This intelligent control method greatly improves the flexibility and practicality of the equipment; the present invention has exquisite design, good safety, wide applicability, and high work efficiency. It has important practical guiding value for the application of drones and tree obstacle clearing tools in high-altitude operations, and has good economic and social benefits; in addition, the equipment also has good environmental adaptability, and can operate stably in complex and changeable high-altitude environments, effectively solving many problems encountered in traditional tree obstacle clearing methods, and injecting new vitality into the development of the power industry.
