DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-6 The embodiment provided by the present application: a natural gas pipeline daily inspection unmanned aerial vehicle, comprising an unmanned aerial vehicle body 1, one side of the bottom of the unmanned aerial vehicle body 1 is provided with a marking assembly 3.

[0026] The marking component 3 includes a storage bin 31, a second limiting rod 32, a baffle 33, a conical head 34, an electric push rod 35, an inclined surface cover plate 36, a pin 37, a counterweight 38, a push plate 39, a second spring 310, a fluorescent rod 311, an installation bin 312, a third spring 313 and a discharge port 314. The storage bin 31 is located on one side of the bottom of the UAV body 1. On one side inside the storage bin 31, multiple groups of second springs 310 are evenly arranged. On one side of the multiple groups of second springs 310, there is a push plate 39. At the bottom of the storage bin 31, there is an inclined surface cover plate 36. There is a through groove at the bottom of the storage bin 31, and the inclined surface cover plate 36 is located inside the through groove. On both sides of the inclined surface cover plate 36, connecting plates are symmetrically arranged, and the connecting plates are connected to the storage bin 31 through bolts, which is convenient for filling the counterweight 38, the inclined surface cover plate 36 and the fluorescent rod 311. On the top of the inclined surface cover plate 36, multiple groups of pins 37 are slidably connected. On the top of the pins 37, there is a counterweight 38. On the top of the counterweight 38, there is a fluorescent rod 311. At the top of one side of the storage bin 31, there is an electric push rod 35. At the top of one side of the storage bin 31, there is an extended bin, and the electric push rod 35 is located inside the extended bin, which is convenient for installation. The output end of the electric push rod 35 is provided with a conical head 34. On one side of the conical head 34, there is a second limiting rod 32. On one side of both ends of the storage bin 31, installation bins 312 are symmetrically arranged. Inside the installation bins 312, multiple groups of third springs 313 are arranged. One end of the third spring 313 is provided with a baffle 33. On one side of the bottom of the storage bin 31, there is a discharge port 314. During the inspection process, if the UAV finds cracks in the pipeline, it can directly mark the nearby positions, which is convenient for subsequent maintenance personnel to locate the cracked positions, avoiding the maintenance personnel from searching for positions for a long time and improving the convenience of maintenance;

[0027] On the other side of the bottom of the UAV body 1, there is an installation frame 4. Inside the installation frame 4, there is a camera 6. At the bottom of the camera 6, there is a high-resolution infrared thermal imager 5. On the outer wall of the UAV body 1, multiple groups of folding propeller assemblies 2 are arranged;

[0028] The folding propeller assembly 2 includes a connecting frame 21, a first spring 22, a plug rod 23, a propeller 24, a propeller drive motor 25, a guide groove 26, a fixing hole 27, a hinge rod 28, a first limit rod 29, a locking hole 210, and a locking bolt 211. The connecting frame 21 is located on both sides of the UAV body 1. The hinge rod 28 is hinged inside the connecting frame 21. A fixing hole 27 is provided on one side of the top of the hinge rod 28. A plug rod 23 is provided on one side of the top of the connecting frame 21. The plug rod 23 is located inside the plug hole, allowing the plug rod 23 to move in a straight line. The bottom of the plug rod 23 extends into the interior of the fixing hole 27. The outer side of the plug rod 23 is provided with... The device includes a first spring 22, a limiting plate at the bottom of the insertion rod 23, and the first spring 22 located at the top of the limiting plate. As the insertion rod 23 moves upward, it can compress the first spring 22. A guide groove 26 is provided on one side of the top of the hinge rod 28. A first limiting rod 29 is slidably connected inside the guide groove 26. A propeller drive motor 25 is provided at the top of the first limiting rod 29. A propeller 24 is provided at the output end of the propeller drive motor 25. A locking hole 210 is provided at one end of the first limiting rod 29, and a locking bolt 211 is provided at one end of the hinge rod 28. This device can fold the drone, thereby reducing its size and allowing it to be stored in the inspection vehicle, improving storage convenience.

[0029] Working principle: Before the drone inspection process, firstly, the insertion rod 23 is pulled upward, then the hinge rod 28 is flipped. After flipping to the designated position, the insertion rod 23 is released. At this time, the first spring 22 resets and pushes the insertion rod 23 downward, so that the insertion rod 23 is inserted into the fixed insertion hole 27, thereby limiting the hinge rod 28. Then, the propeller drive motor 25 and the propeller 24 are pulled outward. After being pulled to the limit position, the locking bolt 211 is rotated, so that the locking bolt 211 enters the locking hole 210, thereby locking the first limit rod 29, completing the fixation of the propeller drive motor 25 and the propeller 24, and completing the drone deployment. At this time, the drone body 1, propeller drive motor 25, high-resolution infrared thermal imager 5 and camera 6 are started, so that the drone can inspect according to the pre-set route. Due to the temperature gradient formed between the cracked area and the intact area due to the difference in heat conduction, the high-resolution infrared thermal imager 5 captures the temperature distribution on the pipe surface, and then combines the heat conduction characteristics to identify crack defects.

[0030] During the inspection process, if the drone discovers any excavation above or near the pipeline, camera 6 will promptly take photos and record the information, and send an alarm to the backend computer. If there are any illegally encroaching devices on the nearby road, camera 6 will record the image and send an alarm to the backend computer. Furthermore, if the drone's battery is low during the inspection, it will promptly fly back to recharge.

[0031] When a crack is detected, the electric push rod 35 is activated, which then pushes the conical head 34 and the second limit rod 32 to move. During the movement, the conical head 34 pushes the two sets of baffles 33 to separate, so that the baffles 33 no longer block the counterweight 38. At this time, the second spring 310 resets and pushes the push plate 39 to move. Then the push plate 39 pushes multiple sets of counterweights 38, inclined cover plates 36 and glow sticks 311 to move together, so that the foremost counterweight 38, pin 37 and glow stick 311 fall from the height along the outlet 314. During the fall, affected by the center of gravity, the position of the pin 37 is downward, and then the pin 37 is inserted into the surrounding soil to mark the position.

[0032] After the frontmost counterweight 38, inclined cover plate 36, and glow stick 311 fall, the second limiting rod 32 will move along with the conical head 34, thus preventing the glow stick 311 at the rear from moving and avoiding the counterweight 38, inclined cover plate 36, and glow stick 311 falling out together. When the electric push rod 35 drives the conical head 34 and the second limiting rod 32 back to their initial positions, the second limiting rod 32 will no longer restrict the glow stick 311. At this time, the counterweight 38, inclined cover plate 36, and glow stick 311 will fill the position of the baffle 33.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
