Description

Technical Field

[0001] The invention belongs to the field of unmanned aerial vehicle applications, and in particular relates to a buffer-type high-altitude fault elimination device based on an unmanned aerial vehicle. Background Art

[0002] At present, unmanned aircraft is referred to as "drone", abbreviated as "UAV" in English. It is an unmanned aircraft controlled by radio remote control equipment and self-contained program control devices. Drones are actually a general term for unmanned aerial vehicles. Drones are used to inspect various power equipment for power transmission, so that power regulatory departments can find problems and maintain them in time to ensure the normal operation of the power transmission network. The drone inspection method has the advantages of high efficiency, fast, reliable, low cost, and no geographical influence.

[0003] Not only as mentioned above, the existing "UAV saw blade cutting obstacle removal and transformer oil detection device" disclosed in patent application CN105356374 adopts the method of "the first camera 6 observes the cutting process of the saw blade 7 on the obstacle from multiple positions, thereby reducing the possibility of the UAV saw blade cutting obstacle removal and transformer oil detection device damaging the wires" to use a drone to remove the fault location in the power system.

[0004] However, since the drone is in the air and carries many devices such as cameras and ultrasonic waves, it will cause a large degree of vibration when removing the fault location, making it difficult for ground personnel to operate. Summary of the invention

[0005] In view of the problem of vibration caused by UAV cutting at the fault location in the prior art, the present invention provides a buffer-type high-altitude fault elimination device based on a UAV, which can form a buffer structure between the cutter head and the cutter disc, thereby reducing the impact of vibration.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a buffered high-altitude fault elimination device based on a drone, comprising a drone, a bracket arranged on the drone, a cutter head assembly arranged at the end of the bracket, and a camera assembly arranged on the bracket and located between the drone and the cutter head assembly, wherein the cutter head in the cutter head assembly is embedded in a groove on the cutter disc, and the vibration generated by the cutter head during cutting is buffered by the side wall of the cutter disc groove.

[0007] Among them, the cutter head assembly includes a cutter head, a cutter disc, a motor and a fixing cap; the cutter disc is evenly distributed with grooves for placing the cutter head; the motor is arranged on the bracket through a motor seat; the cutter disc is arranged on the output end of the motor and the cutter disc and the output end of the motor are fixed together through a fixing cap.

[0008] Beneficial effect: The cutter head of the present invention is arranged in the cutter disc, and the cutter disc is made of carbon fiber, which has a certain elasticity. When the cutter head rotates at high speed for cutting, the side wall of the cutter disc can cushion the cutter head, thereby reducing vibration. The present invention has a simple structure and good shock absorption effect, improves the stability of the UAV, and is convenient for operators to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] like Figures 1-2 The buffer-type high-altitude fault elimination device based on a drone comprises a drone 1, a bracket 2 arranged on the drone 1, a cutter head assembly 3 arranged at the end of the bracket 2, and a camera assembly 4 arranged on the bracket 2 and located between the drone 1 and the cutter head assembly 3. The cutter head 301 in the cutter head assembly 3 is embedded in a groove on a cutter disc 302, and the vibration formed by the cutter head 301 during cutting is buffered by the side wall of the groove of the cutter disc 302.

[0016] The camera assembly 4 is arranged on the bracket 2 through the fixing seat 5; the camera assembly 4 includes a high-definition aerial camera and an airborne LB2 image transmission system. The drone 1 is tied with a 12v lithium battery LiP0 for power supply, and the camera assembly 4 transmits image data in real time when working, which is convenient for operators to handle defects.

[0017] Specific implementation I, such as Figure 3 The cutter head assembly 3 includes a cutter head 301, a cutter disc 302, a motor 303 and a fixing cap 304; wherein the cutter disc 302 is evenly distributed with grooves 302A for placing the cutter head 301; the motor 303 is arranged on the bracket 2 through the motor seat 4; the cutter disc 302 is arranged on the output end of the motor 303 and the cutter disc 302 and the output end of the motor 303 are fixed together through the fixing cap 304.

[0018] To facilitate connection, an elliptical piece 3031 is coaxially welded on the output end of the motor 303; a stud is welded to one end of the elliptical piece 3031 that is connected to the fixing cap 304; an internal thread is provided in the fixing cap 304; an elliptical mounting hole that matches the elliptical piece 3031 is provided on the cutter disc 302; and, in order to ensure reliable connection, a threaded hole is also provided on the cutter disc 302; the threaded hole can be used to fix the end face of the elliptical piece 3031, making the connection between the cutter disc 302 and the elliptical piece 3031 more reliable.

[0019] During the application process, the cutter head 301 is set in the groove 302A on the cutter disc 302 by bolts. In order to ensure reliability, the side walls on both sides of the groove 302A that are in contact with the cutter head 301 are provided with protrusions 3021, and the two protrusions are staggered to prevent the cutter head 301 from falling out during cutting. However, since both side walls of the groove 302A are in contact with the cutter head 301, when the cutter head 301 is working, the side wall of the groove 302A will be continuously squeezed, resulting in continuous deformation of the side wall of the groove 302A. After the continuous deformation is formed, the side wall of the groove 302A will be damaged, and over time, the cutter head 301 cannot be fixed.

[0020] Specific implementation II, such as Figure 4 In order to solve the problem in specific embodiment I, the width of the groove 302A is widened, and then protrusions 3021 are provided on the side walls on both sides where the groove 302A contacts the cutter head 301, and the two protrusions are staggered to fix the cutter head 301 when the cutter head 301 is cutting.

[0021] In this embodiment, two staggered protrusions 3021 are used to fix the cutter head 301, and when the cutter head 301 is working, the protrusions 3021 can provide a buffer force for the cutter head 301. However, since the protrusions 3021 are only provided on both sides of the contact of the cutter head 301, it is equivalent to providing a line contact between the cutter head 301 and the side wall of the groove 302A, and the contact area is too small, and the protrusions 3021 are easily deformed and damaged.

[0022] Specific implementation III, such as Figure 5 In order to solve the problem in specific embodiment II, a plurality of buffer protrusions 3022 are provided on the side walls on both sides where the groove 302A contacts the cutter head 301; the buffer protrusions 3022 are arranged at equal distances.

[0023] In this embodiment, multiple buffering protrusions 3022 are used to simultaneously support the cutter head 301. When the cutter head 301 is working, when the cutter head 301 is cutting, a process is required for the force on the cutter head 301 to be transferred from the tip of the cutter to the side wall of the groove 302A. In this process, since multiple buffering protrusions 3022 are arranged on the side wall of the groove 302A, the cutter head 301 is buffered step by step, so that the force between the cutter head 301 and the groove 302A will not increase in an instant, and the effect of buffering and shock absorption is achieved; moreover, since multiple buffering protrusions 3022 are arranged at equal intervals, even if one of the multiple buffering protrusions 3022 is deformed, it will not cause squeezing of the adjacent protrusions, thereby preventing deformation and improving the service life.

[0024] It should be clarified that the material of the blade disc 302 can be carbon fiber.

[0025] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily change or replace the above within the technical scope disclosed by the present invention, which belongs to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
