Description

Technical Field

[0001] The utility model belongs to the technical field related to unmanned aerial vehicle wing detection, and specifically relates to a unmanned aerial vehicle wing surface detection device. Background Art

[0002] Drones, also often referred to as unmanned aerial vehicles or unmanned aerial systems, are aircraft that do not require a human pilot on board. Drones can be operated by remote control, preset flight paths or autonomous flight systems. They are widely used in military, civilian and commercial fields.

[0003] The drone wing is an important component of the drone, responsible for providing lift and horizontal straight force to enable the drone to fly. Drone wing surface inspection is an important maintenance task aimed at ensuring the safety and performance of the drone in flight.

[0004] Although the existing detection device can detect protrusions or depressions on the surface of the drone when in use, it is unable to mark the defective position in time after detecting the defective position, and cannot effectively and intuitively enable the staff to observe the defective position. Moreover, most of the inspections on the surface of the drone wings are carried out by visual inspection. When the staff work for a long time, their eyes will become tired, which will reduce the accuracy of the inspection of the rear wing. Therefore, a drone wing surface detection device is proposed.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model drives the rotating shaft to rotate through the rotation of the motor, and the rotation of the rotating shaft drives the connecting sleeve to rotate. The rotation of the connecting sleeve drives the slider to slide on the surface of the moving rod through the transmission rod. At the same time, due to the movement of the belt and the two sets of pulleys, the moving rod can drive the first slide bar to slide inside the first triangular block during the movement. When the first slide bar moves horizontally inside the first triangular block, the moving rod can drive the detection sleeve inside the installation bin to detect the pits or protrusions on the surface of the wing, which can improve the detection result. At the same time, when the rotating shaft rotates, the cam pushes the piston rod to slide inside the piston cylinder, which can clean the surface of the wing, improve the detection quality, and effectively assist the staff in friction observation.

[0017] 2. The utility model drives the second slide bar to slide inside the second triangular block through the moving rod. The second slide bar can push the connecting rod under the pressure rod to move. The movement of the connecting rod can push the pressure frame to limit the surroundings of the wing, thereby improving the stability during detection.

[0018] 3. The utility model contacts the wing surface through the detection sleeve. When the wing surface encounters a bulge or depression, the detection sleeve moves up and down to drive the wedge block to move. The movement of the wedge block can push the inclined rod to slide inside the conveying column, and can push the conveying column to move up and down. The pigment inside the liquid storage tank can flow to the defective position through the through hole opened on the surface of the detection sleeve and mark it. This not only enables the staff to know the defective position effectively and intuitively, but also avoids the problem of eye fatigue caused by long-term work of the staff, which reduces the problem of detection quality.

DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 , the utility model provides a technical solution: a UAV wing surface detection device, comprising a housing 1, wherein a detection mechanism for detecting the surface of the UAV wing is arranged inside the housing 1;

[0028] In order to facilitate the inspection of the surface of the wing, and to effectively reduce the labor intensity of the staff and improve the inspection quality, the inspection mechanism includes a motor 2, the motor 2 is fixedly connected to the housing 1, the output end of the motor 2 is fixedly connected to the rotating shaft 3, one end of the rotating shaft 3 is fixedly connected to the connecting sleeve 5, the surface of the rotating shaft 3 is connected to the belt 4 through a pulley transmission, the other end of the connecting sleeve 5 is rotatably connected to the transmission rod 6, one end of the transmission rod 6 is rotatably connected to the slider 7, one side of the slider 7 is slidably connected to the moving rod 8, and the lower part of the moving rod 8 is fixedly connected to the installation bin 11;

[0029] Furthermore, in order to facilitate marking of the detected defect positions and improve the work quality of the staff, several groups of liquid storage tanks 12 are installed above the installation bin 11, and several groups of detection sleeves 21 are slidably connected inside the installation bin 11. The inside of the moving rod 8 is rotatably connected with the first slide bar 9 and the second slide bar 17. One end of the first slide bar 9 is slidably provided with a first triangular block 10, and one end of the second slide bar 17 is slidably provided with a second triangular block 18.

[0030] Furthermore, in order to facilitate improving the stability of the wing during the inspection process and improve its inspection quality, the second triangular block 18 is internally slidably connected with a pressure rod 26, a connecting rod 19 is fixedly connected below the pressure rod 26, a pressure frame 20 is fixedly connected below the connecting rod 19, and a sponge pad is provided at the bottom of the pressure frame 20.

[0031] In order to facilitate marking of the detected concave or convex positions, two groups of wedge blocks 25 are fixedly connected inside the detection sleeve 21. The wedge blocks 25 are provided with inclined rods 24 through inclined sliding surfaces. The surface of the inclined rods 24 is slidably connected with a conveying column 22. A plurality of through holes are opened above the conveying column 22, and the conveying column 22 is connected to the inside of the liquid storage tank 12.

[0032] In order to facilitate the application of paint to the defective position and facilitate observation and processing by the staff, the first triangular block 10 and the second triangular block 18 are fixedly connected to the outer shell 1, a plurality of baffles 23 are fixedly connected above the conveying column 22, a plurality of through holes are provided at the connecting position between the liquid storage tank 12 and the conveying column 22, and the inclined surfaces of the wedge block 25 are arranged in opposite directions.

[0033] Furthermore, in order to improve the marking effect and effectively improve the stability of the detection, a spring column is arranged between the detection sleeve 21 and the conveying column 22, a plurality of drainage holes are opened inside the detection sleeve 21, and a reset element is arranged between the pressure frame 20 and the outer shell 1. The first triangular block 10 and the second triangular block 18 are the same size, but the second slide bar 17 and the first slide bar 9 have different diameters.

[0034] Furthermore, in order to improve the accuracy of detection and effectively increase the speed of paint drying, a cam 13 is fixedly connected to the surface of the rotating shaft 3, a piston rod 14 is slidably arranged below the cam 13, a piston cylinder 15 is slidably connected to the surface of the piston rod 14, and an air outlet pipe 16 is fixedly passed through the bottom of the piston cylinder 15.

[0035] In order to improve the effect of high-pressure gas on impurities removal, the surface of the outlet pipe 16 is fixedly connected with multiple groups of jets, the outlet pipe 16 is fixedly connected to the shell 1, and the jets are inclined at a certain angle on the surface of the outlet pipe 16.

[0036] The working principle and use process of the utility model are as follows: after the utility model is installed, the wing to be inspected is first placed inside the shell 1, and then the pigment is added into the liquid storage tank 12, and then the motor 2 is started to rotate to drive the rotating shaft 3 to rotate, and when the rotating shaft 3 rotates, the connecting sleeve 5 is driven to rotate, and when the connecting sleeve 5 is driven, the transmission rod 6 is driven to rotate, and the transmission rod 6 rotates while driving the slider 7 to slide on the surface of the moving rod 8. At this time, the slider 7 can push and drive the moving rod 8 to move, and at the same time, the movement of the moving rod 8 will drive the first slide bar 9 to slide inside the first triangular block 10, so that the movement trajectory of the moving rod 8 is the same as the movement trajectory of the first slide bar 9. Because the belt 4 is driven to rotate by the pulley when the rotating shaft 3 rotates, the rotation of the belt 4 will drive another set of pulleys, so that the slider 7 can slide smoothly on the surface of the moving rod 8, thereby starting the work of pushing the moving rod 8 upward, so that the moving rod 8 drives the detection sleeve 21 inside the lower mounting bin 11 to detect the pits and protrusions on the wing surface.

[0037] When the moving rod 8 moves to drive the first slide bar 9 to move horizontally inside the first triangular block 10, the wing is inspected through the detection sleeve 21. At the same time, the movement of the moving rod 8 drives the second slide bar 17 to make the same movement inside the second triangular block 18. When the second slide bar 17 also moves horizontally inside the second triangular block 18, the second slide bar 17 will press the pressure rod 26 downward. When the pressure rod 26 moves, it will push the pressure frame 20 to move downward inside the shell 1 through the connecting rod 19, so that the wing can be simply limited around and the stability of the wing surface can be improved.

[0038] When the moving rod 8 drives the installation bin 11 to move horizontally, the installation bin 11 drives the detection sleeve 21 to slide on the surface of the wing. When encountering a protrusion, the detection sleeve 21 moves upward inside the installation bin 11. The movement of the detection sleeve 21 pushes the inclined rod 24 through the wedge block 25. At this time, the movement of the inclined rod 24 through the inclined surface pushes the conveying column 22 to move upward. When the conveying column 22 moves to the specified position, the pigment inside the liquid storage tank 12 flows from the surface of the conveying column 22 to the through hole set below the detection sleeve 21, thereby detecting the surface of the defective position. On the contrary, when the detection sleeve 21 encounters a concave position, the conveying column 22 will be driven to move downward again through the sliding of the inclined rod 24. At this time, the spring column releases the top force on the conveying column 22, so that the conveying column 22 will move downward. The movement of the conveying column 22 will drive the multiple groups of baffles 23 to move inside the liquid storage tank 12, so that the pigment inside the liquid storage tank 12 can flow from the inside of the conveying column 22 to the through hole of the detection sleeve 21 below for marking, which can not only effectively improve the efficiency of detection, but also enable the staff to quickly and accurately determine the location of the defect, and the work efficiency is high;

[0039] When the rotating shaft 3 rotates, it will drive the cam 13 to rotate. The rotation of the cam 13 can push the piston rod 14 to slide inside the piston cylinder 15, and the high-pressure gas can be sprayed onto the surface of the wing to be inspected through multiple groups of jet nozzles arranged on the surface of the outlet pipe 16. On the one hand, it can clean the impurities adhering to the surface of the wing and improve the accuracy of the detection. On the other hand, it can speed up the drying efficiency of the paint applied to the defective position, and the work efficiency is high.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
