Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) equipment, and in particular to an electromagnetic adsorption device based on a UAV. Background Art

[0002] Unmanned aerial vehicles (UAVs), also known as "drones," are unmanned aircraft controlled by radio remote control and self-contained program control devices, or operated completely or intermittently autonomously by an onboard computer. Compared to manned aircraft, drones are often more suitable for tasks that are too "dull, dirty, or dangerous." High-voltage power line maintenance requires climbing, which requires tools. First, a traction tool must be suspended on the high-voltage line, which is impossible with a traditional ladder. In these cases, a drone is generally needed to assist in climbing. To facilitate grasping and cutting the tool, a mechanical claw is generally used. However, mechanical claws are difficult to position during grasping. Therefore, a drone-based electromagnetic adsorption device is now provided. This uses magnetic adsorption to complete grasping and release, thus eliminating the disadvantage of the mechanical claw requiring docking. Summary of the Invention

DETAILED DESCRIPTION

[0021] Example 1

[0022] See also Figures 1-4In an embodiment of the present invention, an electromagnetic adsorption device based on a drone includes a drone body 11 and an array of telescopic rods 24 distributed on the outside thereof. A brushless motor 21 is provided at the outer end of each telescopic rod 24. A blade 22 is provided at the output end of the brushless motor 21. A protective ring 23 for protection is provided on the outer side of the blade 22. The protective ring 23 is connected and fixed to the outer side of the brushless motor 21 through a connecting rod. A leg member is provided at the lower end of each brushless motor 21. An electromagnetic block 15 for adsorbing climbing tools is provided below the drone body 11. A wire assembly 13 for transmitting electrical signals is provided between the electromagnetic block 15 and the drone body 11. The outer side of the electromagnetic block 15 A protective shell 16 is provided for protection, and a plurality of traction links 17 are rotatably provided on the outer side of the protective shell 16. The number and position of the traction links 17 correspond to the telescopic rod 24. The outer end of each traction link 17 is rotatably connected to the outer side of the brushless motor 21. In this way, when flying, the telescopic rod 24 is extended, and the traction link 17 and the telescopic rod 24 are close to each other, reducing the wind resistance generated during flight. The drone body 11 is provided with a battery for power supply. The drone body 11 is also provided with a controller electrically connected to the electromagnetic block 15, the telescopic rod 24, the brushless motor 21 and the wire assembly 13. The controller is electrically connected to a wireless module for wireless interaction with the control terminal.

[0023] The wire assembly 13 includes a storage chamber 29 arranged inside the drone body 11, and a fixed rotating shaft 30 is rotatably provided inside the storage chamber 29. A winding roller 28 for winding the wire 26 is provided on the fixed rotating shaft 30. The left end of the fixed rotating shaft 30 is connected and fixed to the inner wall of the storage chamber 29 by a coil spring 25. The lower end of the wire 26 is electrically connected to the input end of the electromagnetic block 15. A through-hole is provided on the lower side of the storage chamber 29 to facilitate the wire 26 to pass through. A reciprocating swinging member is provided at the through-hole position to facilitate the wire 26 to be evenly wound around the winding roller 28. In actual use, when the electromagnetic block 15 moves downward, the traction force generated by the gravity of the electromagnetic block 15 will drive the winding roller 28 to rotate, and the wire 26 on the winding roller 28 will be automatically released. When the electromagnetic block 15 moves upward, the coil spring 25 will assist the winding roller 28 to rotate, thereby realizing the winding of a single wire 26;

[0024] The reciprocating swinging member includes a guide ring 33 slidably set at the penetration position, the guide ring 33 is provided with a circular hole for the wire 26 to pass through, the outer side of the guide ring 33 is provided with a sliding groove, the sliding groove is slidably matched with the penetration position, a guide rod 32 is provided on one side of the guide ring 33, and a guide column is provided on the upper end of the guide rod 32, the guide column is slidably matched with the rotary groove 31 on the winding roller 28, when the winding roller 28 rotates, the rotary groove 31 will generate a force on the guide column, so that the guide ring 33 slides back and forth at the penetration position, thereby ensuring that the wire 26 is evenly wound on the winding roller 28, and the rotary groove 31 is staggered with the winding position of the wire 26;

[0025] An isolation ring is provided on the winding roller 28 between the rotary groove 31 and the winding position of the conductor 26;

[0026] The telescopic rod 24 includes a main arm fixedly connected to the outside of the drone body 11, a secondary arm is slidably fitted at the outer end of the main arm, a sealing ring is provided between the inner end of the secondary arm and the inner wall of the main arm, and adjacent secondary arms are also slidably sealed, and the air vents at the inner end of each main wall are connected to the cache box 12 inside the drone body 11 through an air duct, the air inlet end of the cache box 12 is connected to an air pump for inflating air therein, and the exhaust end of the cache box 12 is provided with an exhaust pump for discharging the gas therein. When the air pump inflates the cache box 12, each telescopic rod 24 extends outward, and when the telescopic rod 24 extends, the end of the traction link 17 will be pulled, so that the electromagnetic block 15 is close to the bottom of the drone body 11 for storage;

[0027] On the contrary, when the exhaust pump removes the gas inside the buffer box 12, the secondary arm will be retracted into the main arm under the action of negative pressure. At this time, the inner end of the traction link 17 will move downward, thereby causing the electromagnetic block 15 to extend downward to absorb the tool.

[0028] This storage structure can effectively prevent the wires between the electromagnetic block 15 and the drone body 11 from being damaged;

[0029] The lower end of the drone body 11 is provided with a protective frame 14 for accommodating the electromagnetic block 15, so that the electromagnetic block 15 can be stored inside it when not in use. The outer side of the protective frame 14 is provided with a notch corresponding to the traction link 17;

[0030] The support leg member includes a fixed sleeve 20 provided at the lower end of the brushless motor 21, a telescopic leg 19 is slidably provided at the lower end of the fixed sleeve 20, the upper end of the telescopic leg 19 is connected to the top of the inner cavity of the fixed sleeve 20 via a buffer spring, and a support foot 18 is provided at the lower end of the telescopic leg 19 for increasing the support area. In this way, when the wind turbine lands, the support foot 18 contacts the ground, and the buffer spring can play a buffering effect, thereby reducing the impact force caused by landing;

[0031] In order to facilitate folding, the traction link 17 can be replaced with a first link connected to the protective shell 16. A first connecting sleeve is slidingly provided at the end of the first link, and a locking knob is provided on the outside of the first connecting sleeve for locking its position with the first link. The other end of the first connecting sleeve is rotatably connected to the brushless motor 21, so that the first connecting rod and the first connecting sleeve can be folded at a later stage, thereby reducing the space occupied by the entire device.

[0032] The working principle of the present invention is as follows: in actual use, the blades 22 are first controlled to work and the drone body 11 is lifted into the air. When the climbing tool needs to be lifted, the electromagnetic block 15 is first energized to generate magnetism, and then the drone body 11 is adjusted to fly above the climbing tool so that the electromagnetic block 15 adsorbs the tool, and then the drone body 11 is lifted above the high-voltage line. When the climbing tool is released, the gas inside the buffer box 12 is extracted by the exhaust pump. Under the action of negative pressure, the secondary arm will be retracted into the main arm. At this time, the inner end of the traction link 17 will move downward, thereby causing the electromagnetic block 15 to extend downward, so that the climbing tool is suspended on the high-voltage line. Then, the power of the electromagnetic block 15 is disconnected, and the magnetism disappears, thereby completing the rapid suspension. In the later stage, it is only necessary to fly the drone body 11 to the climbing tool position, and then make the electromagnetic block 15 close to the tool adsorption surface, and then energize to complete the adsorption. Then, the climbing tool is removed from the high-voltage line. When releasing, the electromagnetic block 15 is set away from the drone body 11, so that the drone body 11 is as far away from the high-voltage line as possible, thereby improving the safety of operation.
