Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV inspection device for power grid lines. Background Technology

[0002] In power systems, regular inspections of power grid lines are necessary to ensure normal operation of power grid communication. Inspections and detections have broad application needs. However, due to the height of power lines and complex terrain, they are difficult to inspect, and the operating environment presents high-voltage risks. Therefore, using drones for power grid line inspections has become commonplace. Chinese patent application number 202010901205.2 discloses "a power grid inspection drone capable of automatically avoiding line discharge range and maintaining a safe distance based on power grid voltage conditions, comprising a frame 1, a parachute compartment 3, a flight control compartment 4, a propeller 5, a protective frame 6, and an inductor coil 13. It is safe and reliable, prevents entry into high-voltage discharge areas, protects the drone's safety, and prevents damage to power facilities."

[0003] While this comparative document can avoid damage to power facilities, it still has some limitations. When drones are inspecting power lines, they are very close to them and are susceptible to electromagnetic interference, which can cause the drones to malfunction. In addition, the drones need to transmit the detected information to the operator, which inevitably involves communication. Furthermore, drones operate at a high altitude and are difficult to control when they encounter external environmental factors such as strong winds. If left unattended, the drones may get stuck on the power lines, damaging not only the power grid but also the drones themselves. Therefore, there is a need for a drone inspection device that can adapt to different external environments. Summary of the Invention

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-8 The present invention provides a technical solution: a power grid line unmanned aerial vehicle inspection device, including a body 1, four wings 2 are fixedly installed on the outside of the body 1 by bolts, propellers 3 are respectively installed on the outer top of the four wings 2, and a high-definition camera is provided at the bottom of the body 1.

[0032] The stabilizing mechanism 4 includes a base block 41, a balance plate 42, and a movable seat 43. The base block 41 is fixedly installed at the middle of the bottom end of the machine body 1 by bolts. The balance plate 42 is fixedly installed at the bottom end of the base block 41 by bolts. The movable seat 43 is located at the bottom end of the balance plate 42.

[0033] Adjustment mechanism 5 includes operating table 51, two translation plates 52 and power block 53. Arc-shaped frames are symmetrically fixed on both sides of the top of the machine body 1 by bolts. The operating table 51 is fixedly installed in the middle of the top of the machine body 1 by snapping with the arc-shaped frames. The two translation plates 52 are respectively set on both sides of the operating table 51. The power block 53 is movably set on the top of the operating table 51.

[0034] The touch component 6 includes a swing sensor 61, which is fitted and installed on the front side of the bottom of the operating table 51. The swing sensor 61 can acquire data on the swing of the machine body 1 and make further analysis and judgment to ensure timely adjustment.

[0035] The stabilizing mechanism 4 also includes four hydraulic buffer rods 44, support rods 45, two limit rods 46, and a locking mechanism 47. The four hydraulic buffer rods 44 are divided into two groups of two. Each group of hydraulic buffer rods 44 is fixedly installed on the front and rear sides of the top of the balance plate 42 by bolts, and is located at the front and rear ends of the machine base block 41. The top of the support rod 45 is fixedly installed inside the machine base block 41 by a snap-fit. The top center of the movable seat 43 has a movable groove. The bottom of the support rod 45 has a spherical structure and is smooth. When the support rod 45 is affected by uneven ground, the bottom of the support rod 45 will generate friction with the wall of the movable seat 43 under the influence of the movable seat 43. Therefore, the spherical structure made of smooth material can enable normal operation. The bottom end of the support rod 45 is located inside the movable groove. The clasp 47 is sleeved and installed at the bottom end of the support rod 45. The cross-section of the clasp 47 is trapezoidal. The bottom end of the clasp 47 is fixedly bonded to the wall of the movable seat 43. The two limit rods 46 are respectively fixedly installed on both sides of the bottom end of the balance plate 42 by bolts. Limiting ports for accommodating the limit rods 46 are opened on both sides of the top end of the movable seat 43, so that the balance plate 42 will not affect the hydraulic buffer rod 44 due to excessive displacement. The movable seat 43 has a rectangular structure. The front and rear sides of the top end of the movable seat 43 are respectively fixedly installed with bolts to provide a certain support force for the movable seat 43.

[0036] The adjustment mechanism 5 also includes two conveyor belts 54 and a straight toothed plate 55. Rectangular fixed slots are opened on both sides of the top of the operating table 51, and an elongated elliptical placement slot is opened in the middle of the top of the operating table 51. The two conveyor belts 54 are fixedly installed in the two fixed slots through rollers distributed at both ends, and are used to convey the power block 53. The bottom end of the power block 53 is fixedly connected to the crossbeam by bolts. The bottom ends of the power block 53 are fixedly connected to the top of the conveyor belts 54 by buckles installed on the crossbeam. The straight toothed plate 55 is located inside the placement slot and is fixedly welded to the bottom wall of the crossbeam. When the power block 53 moves, it will also drive the straight toothed plate 55 to move in the same direction.

[0037] There are gaps between the two conveyor belts 54 and the walls of the operating table 51 located at the fixed slots, and there are gaps between the two straight toothed plates 55 and the walls of the operating table 51 located at the mounting slots. This ensures that the conveyor belts 54 and straight toothed plates 55 can move while avoiding them from hitting the operating table 51 and affecting normal operation. The bottom of the straight toothed plates 55 is connected to several toothed blocks arranged in a rectangular array. The rear of the top of the operating table 51 is connected to an integrally formed placement box 8. The front hinge of the placement box 8 is connected to an opening and closing door. A rotating shaft is rotatably installed inside the placement box 8. The top of the power block 53 has two horizontally arranged mounting holes. The placement box 8 is equipped with a movable and pull-out parachute with its bottom end connected to the mounting holes. In case of an accident, the parachute can be activated to achieve a self-protection function.

[0038] The adjustment mechanism 5 also includes two movable plates 56 and a sliding block 57. Two parallel guide rails 9 are fixedly installed on the front side of the bottom of the operating table 51. The inner groove of the guide rail 9 is provided with an electromagnetic plate 12 close to the wall. The bottom of the two movable plates 56 is connected to a magnetic block. The two movable plates 56 are slidably connected to the guide rails 9 through the magnetic block. The front and rear ends and opposite side walls of the two movable plates 56 are respectively equipped with guide seats 10. The guide seats 10 are threadedly fixed with a shaft 19. The sliding block 57 is movably sleeved and installed around the outside of the shaft 19. When the electromagnetic plate 12 is energized, it can cause the magnetic block to drive the movable plate 56 to move.

[0039] The adjustment mechanism 5 also includes two pull rods 58 and two wire rods 59. One end of each wire rod 59 is wound around the connecting hole of the sliding block 57, and the other end of each wire rod 59 is fixedly welded to the side wall of each of the two translation plates 52. The wire rods 59 provide tension for the movement of the translation plates 52. The bottom sides of the power block 53 and the bottom sides of the two translation plates 52 away from the power block 53 are respectively fixedly installed with a central bearing 20 and a side bearing by bolts. One end of each pull rod 58 is rotatably mounted on the central bearing 20 by a pin, and the other end of each pull rod 58 is rotatably connected to the side bearing. The two pull rods 58 act on the translation plates 52 on both sides respectively.

[0040] The trigger component 6 also includes a trigger box 62. A trigger button 22 is fixedly installed on the inner side wall of the trigger box 62 by fitting. The trigger box 62 is electrically connected to the trigger button 22. The body 1 is equipped with a core processor and a battery. A fan 11 is fixedly installed on the rear side of the bottom of the control panel 51 by a ring frame. The parachute opens immediately when it is blown by the fan 11. The output of the swing sensor 61 is electrically connected to the input of the core processor. The output of the trigger box 62 is electrically connected to the input of the core processor. The output of the fan 11 is electrically connected to the input of the trigger button 22.

[0041] The two translation plates 52 are L-shaped and are staggered at the top of the power block 53. The bottom of the straight tooth plate 55 is provided with a gear 13 that meshes with the tooth block of the straight tooth plate 55. A power roller 14 is fixedly installed between the gear 13 and the touch box 62. The end of the power roller 14 near the gear 13 is fixedly welded to the gear 13. A curved block 21 is fixedly installed at the end of the power roller 14 near the touch box 62 by bolts. The curved block 21 is located inside the touch box 62. When the power roller 14 rotates, it drives the curved block 21 to rotate and touch the touch button 22. After one rotation, the straight tooth plate 55 reaches the front end of the operating table 51 and stops.

[0042] The front end of the fuselage 1 is equipped with a protective cover made of transparent plastic. The inner wall of the fuselage 1 is wrapped with woven mesh, and aluminum foil is wrapped between the wall of the fuselage 1 and the woven mesh. Support frames are fixed to both sides of the bottom of the fuselage 1 by bolts. The wing 2 is equipped with a pressure sensor that is electrically connected to the input end of the core processor. The four propellers 3 are independently connected to four speed control modules that are electrically connected to the output end of the core processor. The output end of the electromagnetic plate 12 is electrically connected to the input end of the core processor. The woven mesh and aluminum foil can prevent electromagnetic interference and ensure good communication of the UAV.

[0043] The bottom block 41 has a threaded hole at its top. The bottom block 41 and the body 1 are fixedly installed with a fastening bracket 15 by bolts. The top center of the fastening bracket 15 has a through hole opposite to the threaded hole. The through hole of the fastening bracket 15 is threaded with a mounting shaft 16 with a curved plate. Several horizontally arranged slots 17 are symmetrically opened on both sides of the top of the fastening bracket 15 with the mounting shaft 16 as the center. Pressure rollers 18 are movably installed in the slots 17 on both sides. The bottom of the slots 17 has a limiting hole integrated with the bottom block 41. The bottom of the pressure rollers 18 is fixedly connected to a support arm that passes through the limiting hole. The bottom of the four upright columns 7 is bonded with a base with a trapezoidal cross section and a frosted bottom. The body 1 is equipped with a radar, a battery compartment, a rangefinder, and a thermal imager.

[0044] Working principle: When using this invention, the operator controls the drone for inspection. It avoids obstacles using radar and captures the location of the power grid lines using a high-definition camera, transmitting the information to the operator. When encountering severe environments such as strong winds, the drone body 1 will be affected by the wind, affecting the rotation of the propeller 3. The drone body 1 will sway and lose flight control. The sway sensor 61 measures the amplitude of the sway of the drone body 1. If the sway amplitude is small, the drone can continue to work and inspect. The sway sensor 61 transmits the obtained information data to the core processor. After analysis, the core processor controls the speed control module to make the corresponding propeller 3 respond and accelerate its rotation, so as to keep the drone as balanced as possible.

[0045] If the swing amplitude is large, the drone activates its self-protection function. Before use, when the power block 53 is close to the placement box 8 and the adjustment mechanism 5 is activated, the core processor module senses a drastic data change in the swing sensor 61, energizing the electromagnetic plate 12, which in turn drives the magnetic blocks to work. The two magnetic blocks move in opposite directions, causing the two moving plates 56 to move in opposite directions. Since the wire rod 59 is fixedly connected to the sliding block 57, and the sliding block 57 is connected to the moving plate 56 through the guide seat 10, the wire rod 59 acts as a pusher for the translation plate 52. Under the action of the wire rod 59, the two translation plates 52 move from... The initial staggered arrangement is located on both sides of the operating table 51. At the same time, the power block 53 is pushed away from the placement box 8 by the pull rod 58. The conveyor belt 54 pushes slightly to make the power block 53 move quickly and stably, opening the parachute. Since the bottom end of the power block 53 is fixedly connected to the straight tooth plate 55, the straight tooth plate 55 drives the gear 13 meshing with it to rotate as it moves. The gear 13 drives the shaft 19 to rotate, and the shaft 19 drives the curved block 21 to rotate, causing the curved block 21 to activate the touch button 22, which then turns on the fan 11 and quickly deploys the parachute. At the same time, the propeller 3 is shut down.

[0046] When it falls to the ground, it will land smoothly because the stabilizing mechanism 4 at the bottom of the machine body 1 will move inside the movable groove through the support rod 45. When the movable seat 43 is tilted, the four hydraulic buffer rods 44 will adjust according to the tilt. When the distance between the balance plate 42 and the movable seat 43 in a certain direction gradually increases, the corresponding hydraulic buffer rod 44 will be lifted up, and the balance plate 42 will always be in a balanced state. The limit rod 46 can prevent the movable seat 43 from tilting too much, causing the balance plate 42 to lose balance, and can play a certain role in stabilizing support. Adjust the pressure roller 18 to be located in the slot 17. Since the support arm passes through the limiting hole, the support arm can directly contact the bottom end of the machine base block 41, so that the support arm supports the machine base block 41, and the fastening frame 15 is aligned and pre-fixed with the machine base block 41. Then rotate the curved plate on the mounting shaft 16, and the bottom end of the mounting shaft 16 is threadedly fixed to the support rod 45.
