Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and specifically to a magnetic attraction structure for UAV landing gear used for power tower maintenance. Background Technology

[0002] A quadcopter, also known as a quadcopter aircraft or quadcopter helicopter, is a type of multi-rotor aircraft. Its four propellers are directly connected to motors and are arranged in a cross shape. By changing the speed of the motors, the force that rotates the fuselage is obtained, thereby adjusting its own attitude. The landing gear on the drone plays a role in supporting and stabilizing the drone, cushioning and shock absorption, protecting the fuselage, and assisting in takeoff and landing.

[0003] For example, Chinese patent CN222179817U proposes a landing gear structure for a drone. This patent achieves aerodynamic shock absorption through the cooperation of a lifting rod and a buffer chamber. Compared with traditional solutions, it solves the defect that the drone cannot quickly come to a stop due to the rebound of spring shock absorption. This avoids the phenomenon of the drone shaking or even falling over due to spring rebound. The setting of the adjusting plug can automatically adjust the air flow rate in the pressure relief groove according to the potential energy of the drone during descent, so that the air pressure inside the buffer chamber can be maintained within a corresponding range. At the same time, the setting of the magnetic block makes it easy to remove the supporting components from the mounting plate and the drone, which facilitates the storage of the drone and the landing gear. However, in this solution, the drone lands on the top of the tower for tower maintenance work, including cleaning, rust removal and replacement and repair. The drone in this solution is only landed on the top of the tower by the landing gear. During maintenance work, the drone body is prone to movement or shaking, which affects the maintenance of the power tower. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a magnetic attraction structure for the landing gear of a drone used for power tower maintenance. This solves the problem that, due to the inevitable wear and tear on drone parts after long-term flight, which necessitates irregular maintenance, the drone is only supported by the landing gear when it lands on the top of the tower. This can easily cause the drone to move or sway during maintenance work, making maintenance inconvenient.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A magnetic structure for the landing gear of a drone used for power tower maintenance includes: a drone body, with first brackets on both sides of the drone body, a magnetic disk assembly on the bottom surface of the first brackets, a second bracket fixedly mounted on the bottom surface of the first brackets, two protective sleeves fixedly fitted onto the outer circular wall of the second brackets, two fixing posts fixedly mounted on the outer circular wall of the second brackets, a fixing block fixedly mounted at one end of each of the two fixing posts, an mounting block fixedly mounted on the bottom surface of the fixing block, an iron core fixedly mounted on the bottom surface of the mounting block, a coil on the outer circular wall of the iron core, an outer disk on the outer circular wall of the coil, and a magnetic block fixedly mounted on the bottom surface of the outer disk.

[0007] In order to perform precise operations while the drone is in flight, the magnetic attraction structure of the drone landing gear for power tower maintenance according to this utility model preferably has a mounting plate on the bottom surface of the drone body, a connecting column fixedly mounted on the bottom surface of the mounting plate, a mounting plate fixedly mounted on the bottom surface of the connecting column, and a robotic arm fixedly mounted on the bottom surface of the mounting plate.

[0008] In order to disassemble the robotic arm, the magnetic attraction structure of the drone landing gear for power tower maintenance of this utility model is preferably provided with a number of threaded holes on the bottom surface of the drone body and the bottom surface of the mounting plate, and the inner circular wall of the threaded holes is threaded with threaded rods.

[0009] In order to capture real-time images of the area while the drone is in flight, preferably, a camera is installed at the bottom of the drone body as part of the magnetic attraction structure of the drone landing gear for power tower maintenance according to this utility model.

[0010] In order to enable the drone to operate at night or in low-light environments, as a magnetic attraction structure for the drone landing gear used for power tower maintenance according to this utility model, preferably, two connecting blocks are fixedly installed on the outer circular wall of the mounting plate, and a searchlight is fixedly installed at one end of each connecting block.

[0011] In order to insulate the coil from the iron core, as the magnetic attraction structure of the UAV landing gear for power tower maintenance of this utility model, preferably, the outer circular wall of the iron core is fixedly sleeved with an insulating layer.

[0012] In summary, the present invention has the following main advantages:

[0013] By setting up an electromagnet component, the coil inside the outer disk can be energized. After the coil is energized, a magnetic field is generated according to Ampere's law. The iron core is magnetized to form a strong magnetic field, which allows the magnetic block to be electromagnetically attracted to the top of the tower. Then, the mechanical arm on the drone can perform maintenance work on the power tower. After maintenance, the current to the coil is cut off, causing the magnetism of the iron core to disappear quickly, releasing the magnetic block from the top of the tower. The power tower maintenance work is then completed, improving the stability of the drone during maintenance. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A magnetic attraction structure for the landing gear of a drone used for power tower maintenance includes: a drone body 1, with first supports 2 on both sides of the drone body 1, a magnetic disk assembly 4 on the bottom surface of the first supports 2, a second support 21 fixedly mounted on the bottom surface of the first supports 2, two protective sleeves 22 fixedly sleeved on the outer circular wall of the second support 21, two fixed posts 3 fixedly mounted on the outer circular wall of the second support 21, a fixed block 5 fixedly mounted at one end of each of the two fixed posts 3, an mounting block 7 fixedly mounted on the bottom surface of the fixed block 5, an iron core 8 fixedly mounted on the bottom surface of the mounting block 7, a coil 10 on the outer circular wall of the iron core 8, an outer disk 6 on the outer circular wall of the coil 10, and a magnetic attraction block 11 fixedly mounted on the bottom surface of the outer disk 6. By setting up the magnetic disk assembly 4, when power tower maintenance is required, the drone body 1 can be landed on the top of the tower using the support of the first supports 2 and the fixed posts 3. The protective sleeves 22 on the second support 21... The sheath 22 can provide cushioning and shock absorption, thereby isolating the fuselage from contact with the ground and preventing friction damage to the fuselage. The UAV mainly consists of a flight platform: fuselage frame, power system, control system, navigation system, communication system, mission payload, and power system, which is the existing structure. The battery in the power system is electrically connected to the coil 10. During maintenance, the battery in the UAV power system can be used to energize the coil 10 in the power disk assembly 4. After the coil 10 is energized, a magnetic field is generated according to Ampere's law. The iron core 8 is magnetized to form a strong magnetic field, which allows the magnetic block 11 to be electromagnetically attracted to the top of the tower. Then, the UAV body 1 can be used to maintain the power tower. After the maintenance is completed, the current in the coil 10 is cut off, causing the magnetism of the iron core 8 to disappear quickly, releasing the attraction between the magnetic block 11 and the top of the tower. This completes the maintenance work on the power tower and improves the stability of the UAV body 1 during maintenance. Example

[0021] Based on the above embodiment 1, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The drone body 1 has a mounting plate 12 on its bottom surface. A connecting column 13 is fixedly mounted on the bottom surface of the mounting plate 12. A mounting plate 14 is fixedly mounted on the bottom surface of the connecting column 13. A robotic arm 19 is fixedly mounted on the bottom surface of the mounting plate 14. The robotic arm 19 can perform precise operations, including gripping tools to inspect power lines during tower maintenance, routinely checking the tower's appearance, coating, and bolt tightness, performing regular maintenance and cleaning, rust removal, and coating repair. Several threaded holes 15 are respectively opened on the bottom surface of the drone body 1 and the bottom surface of the mounting plate 12. Threaded rods 16 are threadedly connected to the inner circular wall of the threaded holes 15. By setting the threaded rods 16, in case the robotic arm 19 malfunctions or is damaged, the threaded rods 16 can be pulled out of the threaded holes 15. The internal screw-out allows for the disassembly of the robotic arm 19, facilitating its maintenance. A camera 20 is installed at the bottom of the drone body 1, enabling real-time capture of the area during drone flight. Two connecting blocks 17 are fixedly mounted on the outer circular wall of the mounting plate 14, with a searchlight 18 fixedly mounted at one end of each block. The searchlight 18 allows the drone body 1 to operate at night or in low-light conditions. An insulating layer 9 is fixedly fitted onto the outer circular wall of the iron core 8, providing insulation between the coil 10 and the iron core 8, ensuring that current flows only within the coil 10. Simultaneously, the iron core 8 guides the magnetic field to concentrate on the magnetic block 11.

[0022] Working principle: Please refer to Figures 1-4 As shown, by setting up the electromagnet component 4, when it is necessary to land on the top of the power tower, the coil 10 inside the outer disk 6 can be energized. After the coil 10 is energized, a magnetic field is generated according to Ampere's law. The iron core 8 is magnetized to form a strong magnetic field, so that the magnetic block 11 can be electromagnetically attracted to the top of the tower. Then, the mechanical arm 19 on the drone body 1 can be used to maintain the power tower. The mechanical arm 19 can perform precise operations and play a role in grasping tools and inspecting lines during the power tower maintenance work. After the maintenance is completed, the current of the coil 10 is cut off, so that the magnetism of the iron core 8 disappears quickly, releasing the attraction between the magnetic block 11 and the top of the tower. Then the maintenance work of the power tower is completed, improving the stability of the drone body 1 during maintenance.
