Description

Technical Field

[0001] This invention belongs to the field of UAV maintenance technology, specifically relating to a UAV inspection and maintenance device. Background Technology

[0002] Whether the drone is being assembled and debugged in the indoor field or tested in the outdoor field, it needs to be inspected and maintained regularly. The drone's landing gear is low. In order to facilitate the maintenance personnel's maintenance and increase the drone's height relative to the ground, maintenance brackets or workbenches are provided to raise the drone's fuselage to a suitable height for maintenance.

[0003] During testing, the drone needs to be placed on a test stand. To ensure stability, the drone's body is fixed to the test stand using fasteners such as external bolts, as the drone needs to be adjusted for movement. While multi-point fixing with bolts is secure, the fixing process is cumbersome and inconvenient to disassemble and assemble. Furthermore, since drones are mostly used for outdoor work, a lot of dust and dirt will remain on their bodies and propellers, as well as dirt that has been eroded by rainwater, which affects their appearance and also makes maintenance inconvenient.

[0004] To address the aforementioned issues, this application proposes a drone inspection and maintenance device. Summary of the Invention

[0040] like Figure 1-10 As shown;

[0041] A drone inspection and maintenance device includes a workbench 1 and a frame 2 installed on the top of the workbench 1. A slip ring mechanism 4 and a camera 7 are sequentially installed on the surface of the crossbeam of the frame 2. An I-beam 6 is hinged to the side of the slip ring mechanism 4 away from the frame 2. A mounting mechanism 5 and a counterweight mechanism 8 are respectively installed at both ends of the I-beam 6. An mounting bracket 51 is installed at the bottom of the mounting mechanism 5.

[0042] In this implementation plan: the drone is placed on the mounting frame 51. At this time, the counterweight mechanism 8 can provide auxiliary counterweight to ensure the stability of the I-beam frame 6 and assist the operator in weighing and testing the drone. The camera 7 is used to monitor the operation process in real time to ensure that the drone maintenance work is fully visible. The camera 7 is equipped with a signal transmission module to upload the captured data to a database or terminal for easy tracing or playback by maintenance personnel later. However, since the drone needs to be adjusted for movement, in order to ensure stability, the drone body will be fixed to the frame with fasteners, such as external bolts. Although the multi-point fixing method with bolts is strong, the fixing process is cumbersome and inconvenient to disassemble and assemble. In addition, since the drone is mostly used for outdoor work, a lot of dust will remain on its body and propellers, as well as dirt attached by rainwater erosion, which affects the appearance and also brings inconvenience to maintenance.

[0043] It should be noted that: the slip ring mechanism 4 includes a conductive slip ring, an anti-rotation shaft, a rhomboid bearing, a fixed shaft, aluminum profiles, and corner pieces. The aluminum profiles are interconnected by the corner pieces to form a support. The rhomboid bearing connects to the top aluminum profile. One end of the anti-rotation shaft is connected to the rhomboid bearing, and the other end passes through a hole in the anti-rotation plate of the conductive slip ring. The inner hole of the conductive slip ring connects to the fixed shaft, and the other end of the fixed shaft is connected to the cantilever aluminum profile through the corner pieces. The counterweight mechanism 8 includes a suspension component, corner pieces, thin plates, and U-shaped connectors. The suspension component connects to the cantilever aluminum profile. Two corner pieces connect to the cantilever aluminum profile and abut against the suspension component from both sides. Two thin plates connect to the suspension component, and the U-shaped connector connects to the thin plates, allowing counterweight plates to be placed on the thin plates. The mounting mechanism 5 includes corner pieces, a suspension component, a three-dimensional force sensor, a rotating body connector, a torque sensor, a bearing connector, a vertical bearing, a carbon fiber rod, and an I-beam frame. The suspension component connects to the cantilever aluminum profile, and two corner pieces connect to the cantilever aluminum profile. The component is connected to the cantilever aluminum profile and abuts against the suspension component from both sides. The three-dimensional force sensor is connected to the suspension component. The rotating body connector connects the three-dimensional force sensor and the torque sensor. The torque sensor is connected to the torque sensor and two vertical bearings through the bearing connector. The carbon fiber rod connects to four vertical bearings. The two outer vertical bearings are connected to the I-beam frame. During the detection operation, when measuring the drone's motion data, the drone is fixed on the mounting mechanism 5. The drone obtains pitch freedom through the mounting mechanism 5. By controlling the throttle and pitch joystick of the drone remote controller, the drone drives the mounting mechanism 5 to perform a 360° rotation, converting the drone's straight forward flight motion into circular motion. The counterweight mechanism 8 balances the weight of the mounting mechanism 5 at the other end. The slip ring mechanism 4 connects the rotating sensor signal line and the fixed instrument line to measure the drone's pull, torque, attitude angle, and rotor speed at different flight speeds. When measuring static data of the drone, the drone is fixed on the mounting mechanism 5. Pushing the throttle stick of the drone remote controller and keeping it stationary, the three-dimensional force sensor is read to measure the maximum pull of the drone; pushing the yaw stick of the drone remote controller, the maximum torque of the drone is measured.

[0044] The drone inspection and maintenance device also includes a maintenance mechanism 3 installed on the mounting mechanism 5;

[0045] The maintenance mechanism 3 includes a cleaning component 31, a rotating component 32, and a fixing component 33. The cleaning component 31 is installed opposite to each other on both sides of the mounting mechanism 5. The rotating component 32 is installed between the mounting mechanism 5 and the mounting frame 51, and the rotating component 32 is rotatably connected to the mounting frame 51. The fixing component 33 is installed on the side of the mounting frame 51 away from the mounting mechanism 5, and the drone is placed inside the fixing component 33.

[0046] In this implementation plan: the cleaning component 31 performs dust removal and dehumidification operations on the drone while achieving multi-angle cleaning, and the rotating component 32 can rotate the drone as a whole, thereby increasing the cleaning range. Furthermore, the fixing component 33 can quickly install and remove the drone during operation, simplifying the installation and removal steps and making it convenient for operators to use.

[0047] It should be noted that all electrical equipment involved in this product is powered by an external power source.

[0048] In an optional embodiment, the cleaning assembly 31 includes connecting rods 312 fixedly mounted on both sides of the mounting mechanism 5 and a drive motor A311 fastened to one side of the surface of the connecting rods 312 by bolts. A turntable 313 is fixedly mounted at one end of the output shaft of the drive motor A311 inserted into the connecting rod 312. A hinge plate 314 is rotatably connected to one side of the surface of the turntable 313 by a pin. A rack A315 is rotatably connected to one side of the hinge plate 314 away from the turntable 313 by a pin. A half gear 316 is connected to one side of the surface of the rack A315 by tooth meshing. The half gear 316 is installed in a groove opened on one side of the surface of the connecting rod 312, and a connecting frame 317 is welded to one side of the half gear 316 extending out of the surface of the connecting rod 312. A plurality of nozzles 318 are fixedly mounted on the side of the connecting frame 317 away from the half gear 316 in a horizontally equidistant manner.

[0049] In this embodiment: When the cleaning component 31 is working, the electric turntable 313 rotates, causing the turntable 313 to push the rack A315 to reciprocate through the hinge plate 314. At the same time, the rack A315 can push the half gear 316 to drive the nozzle 318 to reciprocate through the connecting frame 317, thereby increasing the working range of the nozzle 318 and facilitating the cleaning operation of the drone.

[0050] It should be noted that the nozzle 318 needs to be connected to an external pipeline for conveying airflow.

[0051] In an optional embodiment, a T-groove is provided on the side of the rack A315 away from the half gear 316, and a limiting block 3151 is slidably connected in the T-groove. The limiting block 3151 extends out of the T-groove and is fixedly connected to the inner wall of the connecting rod 312.

[0052] In this embodiment: This design is used to limit the movement of the rack A315, ensuring the stability of the rack A315 during its movement.

[0053] In an optional embodiment, the side of the connecting frame 317 facing the connecting rod 312 has a semi-arc structure, and the connecting frame 317 has a hollow structure. A through pipe is fixedly provided on the surface of the connecting frame 317 on the side of the nozzle 318.

[0054] In this embodiment, the semi-arc-shaped connecting frame 317 can reduce the contact area with the connecting rod 312, ensure the rotation range of the connecting frame 317, and deliver gas to the nozzle 318 by connecting the through pipe to the external pipeline, thereby performing dust removal and dehumidification operations.

[0055] It should be noted that nozzle 318 can deliver gas through external pipelines to remove dust from the surface of the drone. After the drone has been pre-cleaned, hot air can be delivered to nozzle 318 through pipelines to accelerate the evaporation of moisture on the surface of the drone and achieve dehumidification.

[0056] In an optional embodiment, both ends of the shaft of the half gear 316 are rotatably connected to sliders 3161, and sliders 3161 are slidably connected in the slots opened in the inner wall of the connecting rod 312. A movable block 3162 is inserted into the slider 3161. A spring rod 3163 is fixedly provided on the side of the movable block 3162 inserted into the slider 3161, and the end of the spring rod 3163 away from the movable block 3162 is fixedly connected to the inner wall of the slider 3161. A rectangular protrusion 3164 is welded on the side of the slider 3161 away from the movable block 3162, and the protrusion 3164 is inserted into the corresponding slots opened in the inner wall of the connecting rod 312.

[0057] In this embodiment: Pulling the connecting frame 317 causes the half gear 316 to move the slider 3161 downwards, while the movable block 3162 retracts into the slider 3161 and pushes the half gear 316 to a suitable position. At this time, the connecting frame 317 is released, and the spring rod 3163 rebounds under force, pushing the movable block 3162 out of the slider 3161 and abutting against the groove of the connecting rod 312. At the same time, the protrusion 3164 is engaged in the corresponding slot, and the half gear 316 meshes with the gear A315, completing the adjustment of the position of the nozzle 318 and further increasing the working range of the nozzle 318.

[0058] In an optional embodiment, the rotary assembly 32 includes a drive motor B321 fixedly disposed in a mounting groove on the surface of the mounting mechanism 5. One end of the output shaft of the drive motor B321, which passes through the surface of the mounting mechanism 5, is fixedly provided with a connecting shaft 323. A gear B324 is fixedly sleeved on one side of the surface of the connecting shaft 323, and a gear C325 is meshed on one side of the surface of the gear B324. One end of the gear C325 is rotatably connected to the surface of the mounting mechanism 5, and the other end of the gear C325 is fixedly connected to the surface of the mounting bracket 51.

[0059] In this embodiment: In conjunction with the above, when the drive motor B321 drives the gear B324 to rotate through the connecting shaft 323 during operation, the gear B324 can be synchronously rotated by the fixed drone lowered by the gear C325, thereby assisting the operator to clean the drone through the nozzle 318.

[0060] In an optional embodiment, a movable groove A is formed on the surface of the connecting shaft 323 on one side of the gear B324, and a slide rod A3221 is welded into the movable groove A. A sliding sleeve A3223 and a spring A3222 are slidably fitted onto the surface of the slide rod A3221 in sequence. The sliding sleeve A3223 is fixedly connected to the connecting shaft 323 by the spring A3222. A gear A322 is welded to one side of the sliding sleeve A3223 extending out of the movable groove A, and one side of the gear A322 is connected to the gear B324. The surfaces of the gear A322 are in contact with each other. One side of the surface of the gear A322 has a groove, and a slide rod B3263 is welded in the groove. A spring B3261 and a slide sleeve B3262 are slidably mounted on the surface of the slide rod B3263 in sequence. The slide sleeve B3262 is fixedly connected to the gear A322 through the spring B3261. An L-shaped push block 326 is welded to one side of the slide sleeve B3262 extending out of the surface of the gear A322. One side of the push block 326 is inserted into the socket opened on the surface of the gear B324.

[0061] In this embodiment: the push gear A322 is moved to a suitable position along the slide rod A3221 via the sliding sleeve A3223. At this time, the spring B3261 is pushed back by the force and pushes the push block 326 to move through the sliding sleeve B3262 until the push block 326 is inserted into the socket of the gear B324, thus fixing the gears A322 and B324. This assists the operator in rotating the drone and makes it easier for the operator to clean the drone. After pulling the push block 326 to separate it from the gear B324, the gear A322 is pushed down and then the push block 326 is released. The spring A3222 is pushed back by the force and drives the gear A322 to reset through the sliding sleeve A3223, so that the gear B324 can drive the gear C325 to rotate intermittently, assisting the operator in intermittently cleaning the drone.

[0062] It should be noted that the bottom of gear B324 has an inclined surface corresponding to the push block 326, and is adapted to the inclined surface of push block 326, so as to provide motion guidance for push block 326 when pushing gear A322 to move.

[0063] In an optional embodiment, the fixing component 33 includes a drive motor C331 fixedly mounted on the surface of the mounting bracket 51. A gear D332 is welded to one end of the output shaft of the drive motor C331 inserted into the mounting bracket 51. Both sides of the gear D332 are meshed with racks B333. A connecting block 334 is welded to one side of the surface of the rack B333. A guide block 335 is welded to the connecting block 334 at the position facing the through groove on the surface of the mounting bracket 51, and the guide block 335 is slidably connected in the through groove. A connecting plate 336 is welded to the side of the guide block 335 extending out of the through groove, and a baffle 337 is welded to the surface of the connecting plate 336.

[0064] In this embodiment: When the drive motor C331 is in operation, it drives the gear D332 to rotate, so that the rack B333 drives the connecting plate 336 to move relative to each other through the guide block 335, thereby clamping the frame of the drone through the baffle 337, assisting the operator in fixing the drone, simplifying the disassembly and assembly steps, and ensuring operation efficiency.

[0065] In an optional embodiment, a pressure plate 338 is provided between the connecting plates 336 and on one side of the baffle 337. A hinge rod 3382 is hinged in the mounting groove on both sides of the pressure plate 338. The side of the hinge rod 3382 away from the pressure plate 338 is hinged to the surface of the corresponding connecting plate 336. A hollow pad 3381 is welded to the side of the pressure plate 338 facing the baffle 337. A sleeve rod 339 is fixedly provided on the side of the surface of the pressure plate 338 away from the pad 3381. The end of the sleeve rod 339 away from the pressure plate 338 is fixedly connected to the mounting bracket 51.

[0066] In this embodiment: In conjunction with the above, while the connecting plate 336 moves, the connecting plate 336 can push the pressure plate 338 downward through the hinge rod 3382, so that the pressure plate 338 contacts the drone through the pad plate 3381, further ensuring the stability of the drone.

[0067] It should be noted that the sleeve 339 is a telescopic structure used to limit the movement of the pressure plate 338 and ensure the stability of the pressure plate 338 during movement.

[0068] In an optional embodiment, airbags B3385 are fixedly provided on both sides of the opening surface of the pad 3381, and an elastic band 3383 is fixedly provided between the airbags B3385. The side surface of the pad 3381 away from the pressure plate 338 has a number of air holes, and an airbag A3384 is fixedly provided on the surface of the pad 3381 outside the through hole.

[0069] In this embodiment: As described above, while the pressure plate 338 moves, it contacts the drone through the airbag A3384 and continues to press, so that the airbag A3384 is compressed and gas is delivered to the airbag B3385 through the pad plate 3381 to reduce the pressure on the drone. After the drone is removed, the elastic band 3383 is compressed and pulls the airbag B3385 back to its original position, while the other parts spring back into the airbag A3384 for easy use next time.

[0070] The working principle and usage process of this invention: During operation, the drive motor C331 drives the gear D332 to rotate, causing the rack B333 to move relative to the connecting plate 336 via the guide block 335. This, in turn, clamps the drone's frame via the baffle 337. Simultaneously, the connecting plate 336 can push the pressure plate 338 downwards via the hinge rod 3382, causing the pressure plate 338 to contact the drone via the pad 3381 and continue pressing. This compresses the airbag A3384 while simultaneously delivering gas through the pad 3381 to the airbag B3. Within 385, to reduce the pressure on the drone, the connecting bracket 317 is pulled, causing the half gear 316 to move the slider 3161 downwards. At the same time, the movable block 3162 retracts into the slider 3161 and pushes the half gear 316 to the appropriate position. At this time, the connecting bracket 317 is released, and the spring rod 3163 rebounds, pushing the movable block 3162 out of the slider 3161 and abutting against the groove of the connecting rod 312. Simultaneously, the protrusion 3164 engages in the corresponding slot, and the half gear 316 meshes with the gear A315, completing the adjustment of the nozzle 318 position. The pusher gear A322 moves along the slide bar A3221 to a suitable position via the sliding sleeve A3223. At this time, the spring B3261 is forced back and pushes the pusher block 326 through the sliding sleeve B3262 until the pusher block 326 is inserted into the socket of the gear B324, thus fixing gears A322 and B324. This assists the operator in rotating the drone and facilitates cleaning. After pulling the pusher block 326 to separate it from gear B324, the gear A322 is pushed downwards, and then the pusher block 326 is released. The force rebound of 3222 drives the gear A322 to reset through the sliding sleeve A3223, so that the gear B324 can drive the gear C325 to rotate intermittently, assisting the operator in performing intermittent cleaning operations on the drone. When the cleaning component 31 is in operation, the electric turntable 313 rotates, so that the turntable 313 pushes the rack A315 to reciprocate through the hinge plate 314. At the same time, the rack A315 can push the half gear 316 to drive the nozzle 318 to reciprocate and rotate through the connecting frame 317, thereby increasing the working range of the nozzle 318 and facilitating the dust cleaning operation on the drone.
