Description

Technical Field

[0001] This invention relates to a curved tube opposing folding mechanism for a flying robot used for clearing tree obstructions along power lines, and more particularly to a flying robot suitable for quickly clearing large areas of tree obstructions, belonging to the technical field of power transmission line tree obstruction clearing devices. Background Technology

[0002] Tree obstructions pose a safety hazard to power transmission line corridors, manifesting as the continuous growth of trees within the corridors gradually threatening the operational safety of the transmission lines. Therefore, power departments at all levels invest significant manpower, resources, and funds annually in clearing and managing tree obstructions along their jurisdictions. Current tree obstruction clearing methods primarily rely on manual labor, which is inefficient and carries significant safety risks. Therefore, there is an urgent need for an automated flying robot for clearing tree obstructions along power line corridors.

[0003] Patent application CN118270235A, published on July 2, 2024, entitled "A Tree Clearing Flying Robot Using a Rigid-Flexible Hybrid Suspension Mechanism," discloses a tree clearing flying robot that uses a curved pipe to connect naturally suspended cutting tools at the bottom of a drone.

[0004] The above literature has shortcomings in its research on curved tubes for tree-clearing flying robots: using curved tubes of fixed length results in them occupying a large amount of transport space during transportation, causing great inconvenience. Summary of the Invention

[0005] The technical problem solved by this invention is: a curved tube opposing folding mechanism for a tree obstacle clearing flying robot, which connects to a cutting tool system by mounting the curved tube opposing folding mechanism on a multi-rotor flying platform, so as to achieve large-area and high-efficiency clearing of tree obstacles in the power line channel and meet the requirements of safe tree obstacle clearing operation in the power transmission line environment.

[0006] The technical solution of the present invention is as follows: a curved tube opposing folding mechanism for a tree obstacle clearing flying robot, comprising an upper curved tube connected below the flight platform, a lower curved tube connected below the upper curved tube, and the lower part of the lower curved tube being fixedly connected to the working tool; the upper curved tube and the lower curved tube are connected to each other by a locking device and a rotating joint, and its contracted form is a folded "V" shape, and its unfolded form is a hook arc shape.

[0007] Preferably, the bottom of the upper bend is provided with a locking device, and the top of the lower bend is provided with a rotating joint. The locking device can lock the rotating joint, or allow it to rotate freely.

[0008] Preferably, the locking device at the bottom of the upper bend has both limiting and position locking functions.

[0009] Preferably, the upper part of the upper bend is equipped with a rubber buffer layer to reduce collisions after folding in opposite directions during transportation; the upper bend and the lower bend have reinforcing ribs inside to enhance structural strength.

[0010] Preferably, in order to enhance structural strength and allow the lower bend to fold freely without coming loose, the locking device is in a semi-fixed mode.

[0011] The beneficial effects of the present invention are as follows: Compared with the prior art, the present invention has the following advantages:

[0012] 1) The folding mechanism greatly reduces the space required for the bent tube during transportation, effectively utilizing the transportation space;

[0013] 2) The locking device can lock the bend, forming a rigid bend structure, which enhances the flight stability of the flying robot;

[0014] 3) The locking device has a limit function to prevent the lower bend tube from exceeding the limit when the folding mechanism is unfolded. Attached Figure Description

[0024] like Figures 1-5As shown, a curved tube opposing folding mechanism for a tree obstacle clearing flying robot includes an upper curved tube 1 connected to the bottom of the flying platform 3, and a lower curved tube 2 connected to the bottom of the upper curved tube 1. The lower part of the lower curved tube 2 is fixedly connected to the working blade 4. The upper curved tube 1 and the lower curved tube 2 are connected to each other through a locking device 12 and a rotating joint 21. Its contracted form is a folded "V" shape, and its unfolded form is a hook arc shape.

[0025] Preferably, the bottom of the upper bend 1 is provided with a locking device 12, and the top of the lower bend 2 is provided with a rotating joint 21. The locking device 12 can lock the rotating joint 21, or allow it to rotate freely.

[0026] Preferably, the locking device 12 provided at the bottom of the upper bend 1 has both limiting and position locking functions.

[0027] Preferably, the upper part of the upper bend 1 is equipped with a rubber buffer layer 13 to reduce the impact after folding in opposite directions during transportation; the upper bend 1 and the lower bend 2 have reinforcing ribs 5 inside to enhance the structural strength.

[0028] Preferably, in order to enhance structural strength and allow the lower bend 2 to fold freely without coming loose, the locking device 12 is in a semi-fixed mode.

[0029] Preferably, the method of use of the present invention is as follows: when assembling the curved pipe of the flying robot, rotate the rotating joint 21 outward to the maximum angle, and then insert the locking device 12 to fix the upper curved pipe 1 and the lower curved pipe 2; after the flying robot has finished cutting, use the release button to remove the curved pipe, then remove the working tool, then loosen the locking device 12, and then rotate the rotating joint 21 inward to place the lower curved pipe 2 against the rubber buffer layer 13 on the upper curved pipe 1.
