[0002] In the field of wind power generation, aerial photography monitoring drones, with their flexible, efficient, and precise characteristics, have become an important technical means for wind power equipment operation and maintenance, fault detection, and field management.

[0003] The blade is one of the most vulnerable components of a wind turbine. Affected by factors such as airflow impact, lightning, and icing, it is prone to problems such as cracks, notches, wear, and coating peeling. The drone flies around the wind turbine to check for problems such as weld cracking, anti-corrosion coating peeling, bolt loosening, and lightning damage of the wind turbine, especially the detection efficiency of high-altitude parts is significantly higher than that of manual inspection.

[0004] Existing aerial photography monitoring drones often set the monitoring part below the drone, so that the monitoring part can have a wider field of view to monitor the surrounding situation. However, when the monitor is externally exposed below the drone, it is easily touched and impacted by ground stones when the drone lands, and it is extremely easy for the monitor lens to be damaged.

[0005] Based on this, an aerial photography monitoring drone is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. After the UAV takes off, the electric push rod can be remotely activated. The electric push rod drives the monitor frame to descend, and the electric push rod drives the monitor to descend, so that the monitor protrudes from the monitor hole and is located below the UAV box for aerial photography monitoring.

Detailed implementation manners

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In one embodiment, as Figures 1-8 shown, an aerial monitoring unmanned aircraft includes an unmanned aircraft box 1 and a cleaning component 5. Four brackets are arranged on the periphery of the unmanned aircraft box 1, and rotary wings are arranged on the brackets. A monitor hole 2 is opened on the lower surface of the unmanned aircraft box 1. Two symmetric electric push rods 4 are fixedly connected to the inner top wall of the unmanned aircraft box 1. The output ends of the two electric push rods 4 are jointly fixedly connected to a monitor frame 3. A monitor 6 is arranged in the monitor frame 3. The size of the monitor hole 2 is larger than the size of the monitor frame 3;

[0032] The cleaning component 5 is arranged in the unmanned aircraft box 1 and is used for cleaning the lens of the monitor 6.

[0033] After the unmanned aircraft takes off, the electric push rod 4 is started by remote control. The electric push rod 4 drives the monitor frame 3 to descend. The monitor frame 3 drives the monitor 6 to descend, so that the monitor 6 protrudes from the monitor hole 2 and is in the position below the unmanned aircraft box 1 for aerial monitoring. When the unmanned aircraft encounters an impact, the electric push rod 4 can be controlled in time by remote control to drive the monitor 6 into the unmanned aircraft box 1, avoiding the monitor 6 being exposed to the impact and being damaged. And when the unmanned aircraft lands, the monitor 6 can also be controlled to be received into the unmanned aircraft box 1 to protect the monitor 6 from being impacted by stones during the landing of the unmanned aircraft.

[0034] In one embodiment, the cleaning component 5 includes a cleaning frame 7 and a cleaning cloth 8. The bottom wall of the cleaning frame 7 is connected with two symmetrical first rotating shafts 15 through bearings. The first rotating shafts 15 are fixedly connected with driving rollers 20. The two driving rollers 20 cooperate with the cleaning cloth 8 together. The cleaning cloth 8 contacts the lens of the monitor 6.

[0035] During the process of the monitor 6 descending and extending out of the monitor hole 2 and the monitor 6 ascending and entering the drone box 1, the lens of the monitor 6 will contact the cleaning cloth 8, and the cleaning cloth 8 automatically wipes and cleans the dust on the lens of the monitor 6;

[0036] There is no need to manually wipe the lens every time it is used, which greatly reduces the workload of the staff.

[0037] In one embodiment, two mounting frames 32 are fixedly connected to the inner top wall of the drone box 1. The two mounting frames 32 are jointly connected with a third rotating shaft 21 through bearings. One end of the third rotating shaft 21 is fixedly connected with a second gear 26. A second guide rail 25 is fixedly connected to the inner top wall of the drone box 1. A second rack 24 is slidably connected in the track of the second guide rail 25. The second rack 24 is fixedly connected with the output end of one of the electric push rods 4 through a connecting frame. The second gear 26 meshes with the second rack 24. The end of the third rotating shaft 21 away from the second gear 26 is fixedly connected with a turntable 22. The side wall of the turntable 22 is rotatably connected with a first connecting rod 27 through a pin shaft. The end of the first connecting rod 27 away from the turntable 22 is rotatably connected with a second connecting rod 28 through a pin shaft. The end of the second connecting rod 28 away from the first connecting rod 27 is rotatably connected with the cleaning frame 7 through a pin shaft. A second slider 11 is fixedly connected to the lower surface of the cleaning frame 7. A first guide rail 10 is fixedly connected to the inner bottom wall of the drone box 1. The second slider 11 is slidably connected with the inner side wall of the first guide rail 10.

[0038] During the process of the electric push rod 4 driving the monitor frame 3 to rise and fall, the electric push rod 4 drives the second rack 24 to rise and fall. The second rack 24 drives the second gear 26 to rotate. The second gear 26 drives the third rotating shaft 21 to rotate. The third rotating shaft 21 drives the turntable 22 to rotate. The turntable 22 drives the cleaning frame 7 to move horizontally back and forth through the cooperation of the first connecting rod 27 and the second connecting rod 28, so that the cleaning cloth 8 wipes the lens of the monitor 6 back and forth, improving the cleaning effect on the lens of the monitor 6.

[0039] In one embodiment, first slider holes are formed in both the top wall and the bottom wall of the cleaning frame 7. First sliders 9 are slidably connected to the inner side walls of the first slider holes. A tension roller 19 is connected between the two first sliders 9 through a bearing. The tension roller 19, the two driving rollers 20 and the cleaning cloth 8 cooperate with each other. Springs are fixedly connected between the first sliders 9 and the inner walls of the first slider holes.

[0040] The tension roller 19 keeps the cleaning cloth 8 in a tensioned state all the time.

[0041] In one embodiment, the bottom end of the first rotating shaft 15 is rotatably connected to a rotating cylinder 14 through a bearing. The rotating cylinder 14 is fixedly connected to a first gear 13. A one-way card slot 30 is formed inside the rotating cylinder 14. A plurality of ratchet slots 31 are formed on the circumferential side of the first rotating shaft 15. A ratchet 29 is rotatably connected to the inner wall of the ratchet slot 31 through a pin shaft. A spring is fixedly connected between the ratchet 29 and the inner wall of the ratchet slot 31. The ratchet 29 is in one-way clamping connection with the one-way card slot 30. The inner bottom wall of the unmanned aircraft box 1 is fixedly connected to a first rack 12. The first rack 12 meshes with the first gear 13.

[0042] When the electric push rod 4 drives the cleaning frame 7 to move horizontally back and forth, the first rack 12 drives the first gear 13 to rotate. The first gear 13 drives the rotating cylinder 14 to rotate. The one-way card slot 30 of the rotating cylinder 14 cooperates with the ratchet 29, so that the first rotating shaft 15 can only rotate in one direction. That is to say, during the horizontal reciprocating movement of the cleaning frame 7, only when moving in one of the directions, the first rotating shaft 15 will rotate. The rotation of the first rotating shaft 15 drives the cleaning cloth 8 to turn over, so that each different area of the cleaning cloth 8 can contact the lens of the monitor 6. Compared with wiping with a fixed area of the cleaning cloth 8, the wiping effect is better, and the service life of the cleaning cloth 8 can be improved.

[0043] In one embodiment, the bottom wall of the cleaning frame 7 is connected to two symmetric second rotating shafts 16 through bearings. The second rotating shafts 16 are drivingly connected to the first rotating shaft 15 through a synchronous belt driving member 17. A plurality of cams 18 are fixedly connected through the second rotating shafts 16. The cams 18 abut against the cleaning cloth 8. Two symmetric ash falling grooves 23 are formed on the inner bottom wall of the cleaning frame 7. The ash falling grooves 23 are located below the cleaning cloth 8.

[0044] When the first rotating shaft 15 drives the cleaning cloth 8 to turn over, the first rotating shaft 15 drives the second rotating shafts 16 to rotate through the synchronous belt driving member 17. The second rotating shafts 16 drive a plurality of cams 18 to rotate. The protruding parts of the cams 18 continuously contact and impact the cleaning cloth 8, so that the dust on the cleaning cloth 8 is shaken off and falls into the ash falling grooves 23, realizing self-cleaning of the cleaning cloth 8, so that the cleaning cloth 8 always remains clean to clean the lens of the monitor 6, and reducing the frequency of the staff cleaning the cleaning cloth 8. While further improving the cleaning effect of the lens of the monitor 6, the cleaning task amount of the staff is reduced.

[0045] The above embodiment discloses an aerial monitoring unmanned aircraft, and its specific working principle and process are as follows:

[0046] S1: After the drone takes off, start the electric push rod 4 by remote control. The electric push rod 4 drives the monitor frame 3 to descend, and the monitor frame 3 drives the monitor 6 to descend, so that the monitor 6 protrudes from the monitor hole 2 and is located below the drone box 1 for aerial photography monitoring. When the drone encounters an impact, the electric push rod 4 can be promptly controlled by remote control to drive the monitor 6 into the drone box 1, avoiding the monitor 6 being exposed to the impact and being damaged. Also, when the drone lands, the monitor 6 can be controlled to be retracted into the drone box 1 to protect the monitor 6 from being hit by stones during the landing of the drone;

[0047] S2: During the process of the monitor 6 descending and protruding from the monitor hole 2 and the monitor 6 ascending into the drone box 1, the lens of the monitor 6 will contact the cleaning cloth 8, and the cleaning cloth 8 automatically wipes and cleans the dust on the lens of the monitor 6;

[0048] There is no need to manually wipe the lens every time it is used, greatly reducing the workload of the staff;

[0049] S3: During the process of the electric push rod 4 driving the monitor frame 3 to rise and fall, the electric push rod 4 drives the second rack 24 to rise and fall. The second rack 24 drives the second gear 26 to rotate. The second gear 26 drives the third rotating shaft 21 to rotate. The third rotating shaft 21 drives the turntable 22 to rotate. The turntable 22 drives the cleaning frame 7 to move horizontally back and forth through the cooperation of the first connecting rod 27 and the second connecting rod 28, so that the cleaning cloth 8 wipes the lens of the monitor 6 back and forth, improving the cleaning effect of the lens of the monitor 6;

[0050] S4: While the electric push rod 4 drives the cleaning frame 7 to move horizontally back and forth, the first rack 12 drives the first gear 13 to rotate. The first gear 13 drives the rotating cylinder 14 to rotate. The one-way card slot 30 of the rotating cylinder 14 cooperates with the ratchet tooth 29, so that the first rotating shaft 15 can only rotate in one direction. That is to say, during the process of the cleaning frame 7 moving horizontally back and forth, the first rotating shaft 15 will only rotate when moving in one of the directions. The rotation of the first rotating shaft 15 drives the cleaning cloth 8 to turn over, so that each different area of the cleaning cloth 8 can contact the lens of the monitor 6. Compared with wiping with a fixed area of the cleaning cloth 8, the wiping effect is better and the service life of the cleaning cloth 8 can be improved;

[0051] S5: While the first rotating shaft 15 drives the cleaning cloth 8 to turn over, the first rotating shaft 15 drives the second rotating shaft 16 to rotate through the synchronous belt driving member 17, and the second rotating shaft 16 drives a plurality of cams 18 to rotate. The protruding parts of the cams 18 continuously contact and impact the cleaning cloth 8, so that the dust on the cleaning cloth 8 is shaken off and falls into the dust collecting groove 23, realizing the self-cleaning of the cleaning cloth 8, keeping the cleaning cloth 8 always clean to clean the lens of the monitor 6, reducing the frequency of the staff cleaning the cleaning cloth 8, further improving the cleaning effect of the lens of the monitor 6 and reducing the cleaning task amount of the staff.

[0052] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
