Description

Technical Field

[0001] This invention relates to the field of mounting devices, and more specifically, to a mounting device for unmanned aerial vehicles (UAVs) used for flaw detection of power transmission lines. Background Technology

[0002] The transmission line flaw detection drone is a comprehensive inspection tool that integrates high-tech flaw detection equipment and drone technology. It is specifically designed for flaw detection tasks of transmission lines. By carrying X-ray flaw detection equipment or other non-destructive testing instruments, the transmission line flaw detection drone can inspect the internal structure and potential defects of key components (such as tension clamps, crimped pipes, etc.) in the transmission line without interrupting power transmission. At the same time, the transmission line flaw detection drone provides transportation tools and auxiliary equipment for maintenance personnel during the flaw detection process.

[0003] In the prior art, such as in document CN216186103U, a fastening mounting device for a power transmission line inspection drone is specifically disclosed. While this device can assist in transporting the drone to Wuping, when the drone stops, the mounting device contacts the ground first, preventing the drone's bottom feet from making contact with the ground and causing the drone to be unable to stop stably. Therefore, we propose a mounting device for a power transmission line flaw detection drone. Summary of the Invention

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a drone mounting device for power transmission line flaw detection. The connecting frame is fixed to the bottom of the drone with bolts. When the drone is stopped, two electric push rods push the connecting plate to move. The connecting plate drives the support legs to slide along the inner wall of the moving hole on the fixed frame, so that the bottom of multiple support legs extends to below the half frame, thereby providing stable support for the drone.

[0005] To address the aforementioned technical problems, this invention proposes a UAV mounting device for power transmission line flaw detection, comprising a material support assembly for securing materials. A connecting frame is fixedly connected to the top of the material support assembly, and two connecting holes are formed at the top of the connecting frame.

A connecting plate is fixedly connected between two support legs on the same side. Fixing plates are fixedly connected to the outer walls of both fixing frames, and electric push rods are fixedly connected to the inner walls of both fixing plates. The output ends of the two electric push rods are respectively fixedly connected to the corresponding connecting plates.

[0006] Preferably, the material support assembly includes a half-frame and a frame door. The top of the half-frame is fixedly connected to the connecting frame. Two support blocks are fixedly connected to the ends of the half-frame. A rotating shaft is rotatably connected to the inner wall of each of the two support blocks. A torsion spring is sleeved on the outer circumference of each of the two rotating shafts. A limit sleeve is fixedly connected to the ends of each of the two rotating shafts. The two sides of the frame door are fixedly connected to the rotating shafts respectively. A second weight reduction hole is opened on the outer wall of the frame door.

[0007] Preferably, one end of the torsion spring is fixedly connected to the limiting sleeve, and the other end of the torsion spring is fixedly connected to the support block.

Two first slots are provided at the bottom of the frame door, and the ends of the two positioning rods pass through the corresponding first slots and extend to their outer sides.

[0009] Preferably, the outer wall of the frame door is fixedly connected to two limiting blocks. Each limiting block has a sliding hole at its top, a sliding groove on the inner wall of each sliding hole, and a connecting rod slidably connected to the inner wall of each sliding hole. Each connecting rod has a limiting plate fixedly connected to its outer wall, and the limiting plates are slidably connected to the sliding grooves. Each connecting rod has a first spring sleeved on its outer circumference, a fixing sleeve fixedly connected to its outer circumference, and a retaining sleeve fixedly connected to its bottom. Each retaining sleeve engages with a corresponding second retaining groove. Each limiting plate has a first pull ring fixedly connected to its outer wall.

[0010] Preferably, one end of the first spring is fixedly connected to the fixed sleeve, and the other end of the first spring is fixedly connected to the limiting block.

[0011] Preferably, it also includes two trays, with multiple sealing plates fixedly connected to the inner walls of the two trays, and multiple first weight-reducing holes opened on the outer wall of the half frame, with the multiple sealing plates slidably connected to the inner walls of the corresponding first weight-reducing holes.

[0012] Preferably, a first support plate is fixedly connected to each side of the half frame, and two second support plates are fixedly connected between the two support plates. The outer walls of the two first support plates are provided with grooves, and the inner walls of the grooves are fixedly connected with connecting shafts. The outer walls of the connecting shafts are fitted with fixing rods, and the outer walls of the fixing rods are provided with mounting holes. The inner walls of the mounting holes are fixedly connected with sliding rods, and the outer walls of the sliding rods are fitted with second springs.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this invention, the connecting frame is fixed to the bottom of the drone by bolts. When the drone is stopped, two electric push rods push the connecting plate to move. The connecting plate drives the support legs to slide along the inner wall of the moving hole on the fixed frame, so that the bottom of multiple support legs extends to the bottom of the half frame, thereby providing stable support for the drone.

[0017] 2. In this invention, by pressing down multiple second pull rings, the locking rod is moved out of the third slot on the second support plate. By rotating the second pull ring, the second pull ring drives the locking rod to rotate through the fixing rod, moving the locking rod out of the second support plate. After the frame door is opened, by pulling the tray horizontally, multiple sealing plates can be moved out of the half frame, thereby effectively reducing the weight of the half frame. Whether to install sealing plates can be selected according to the size of the items to be transported. Attached Figure Description

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 8As shown, the UAV mounting device for power transmission line flaw detection includes a material support assembly for fixing materials.

Each positioning rod 12 has a second slot 13 on its outer wall. Two first slots 11 are opened at the bottom of the frame door 9. The ends of the two positioning rods 12 pass through the corresponding first slots 11 and extend to their outer sides. Two limiting blocks 14 are fixedly connected to the outer wall of the frame door 9. Each limiting block 14 has a sliding hole 15 at its top. Each sliding hole 15 has a sliding groove 16 on its inner wall. Connecting rods 17 are slidably connected to the inner walls of each sliding hole 15. Limiting plates 20 are fixedly connected to the outer walls of each connecting rod 17. The two limiting plates 20 are slidably connected to the sliding grooves 16. First springs 1 are sleeved on the outer circumference of each connecting rod 17. 9. Fixing sleeves 18 are fixedly connected to the outer circumference of both connecting rods 17, and clips 22 are fixedly connected to the bottom of both connecting rods 17. The two clips 22 are respectively engaged with the corresponding second clips 13. First pull rings 21 are fixedly connected to the outer walls of both limiting plates 20. One end of the first spring 19 is fixedly connected to the fixing sleeve 18, and the other end of the first spring 19 is fixedly connected to the limiting block 14. By simply pulling the two first pull rings 21 upward, the frame door 9 can be unlocked and opened without complicated tools or steps, which greatly improves the convenience of use. This design allows users to quickly and easily open and close the frame door 9, improving work efficiency and user experience.

[0035] like Figure 2 and Figure 3 As shown, it also includes two support plates 3, and multiple sealing plates 4 are fixedly connected to the inner walls of the two support plates 3. Multiple first weight reduction holes 2 are opened on the outer wall of the half frame 1, and the multiple sealing plates 4 are slidably connected to the inner walls of the corresponding first weight reduction holes 2.

[0036] like Figure 9 , Figure 10 and Figure 11 As shown, a first support plate 31 is fixedly connected to both sides of the half frame 1. Two second support plates 33 are fixedly connected between the two support plates 3. The outer wall of each of the two first support plates 31 is provided with a groove 32. The inner wall of each groove 32 is fixedly connected with a connecting shaft 36. The outer wall of each connecting shaft 36 is fitted with a fixing rod 37. The outer wall of each fixing rod 37 is provided with a mounting hole 38. The inner wall of each mounting hole 38 is fixedly connected with a sliding rod 39. The outer wall of each sliding rod 39 is fitted with a second spring 40. The end of each sliding rod 39 passes through the connecting shaft 36 and is slidably connected to it. One end of the second spring 40 is fixedly connected to the connecting shaft 36, and the other end of the second spring 40 is fixedly connected to the inner wall of the fixing rod 37.

The locking rod 41 engages with the corresponding third locking groove 34.

[0037] Working principle: The connecting frame 23 is fixed to the bottom of the drone with bolts. When the drone stops, the two electric push rods 30 push the connecting plate 28 to move. The connecting plate 28 drives the support leg 27 to slide along the inner wall of the moving hole 26 on the fixed frame 25, so that the bottom of the multiple support legs 27 extends to below the half frame 1, thereby providing stable support for the drone.

[0038] By pulling the two first pull rings 21 upward, the first pull rings 21 drive the connecting rod 17 to slide upward along the inner wall of the sliding hole 15 in the limiting block 14 through the limiting plate 20. The connecting rod 17 drives the limiting plate 20 to slide upward along the inner wall of the sliding groove 16. The connecting rod 17 drives the sleeve 22 to move upward. Through the limiting effect of the limiting plate 20, the sleeve 22 can be prevented from rotating. When the connecting rod 17 moves upward, it can compress the first spring 19 until the sleeve 22 moves out of the second slot 13 on the positioning rod 12. At this time, by returning the frame door 9, the frame door 9 is rotated around the pivot 6, so that the frame door 9 can be opened and an object can be placed inside the half frame 1. After placement, the frame door 9 is closed. Under the elastic force of the first spring 19, the connecting rod 17 pushes the sleeve 22 downward and engages with the inner wall of the second slot 13 on the positioning rod 12.

[0039] By pressing down multiple second pull rings 42, the locking rod 41 is moved out of the third slot 34 on the second support plate 33. By rotating the second pull ring 42, the second pull ring 42 drives the locking rod 41 to rotate through the fixing rod 37, moving the locking rod 41 out of the second support plate 33. After opening the frame door 9, by pulling the tray 3 laterally, multiple sealing plates 4 can be moved out of the half frame 1, thereby effectively reducing the weight of the half frame 1. The size of the items to be transported can be selected for whether to install sealing plates 4.
