Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and more particularly to an unmanned aerial vehicle (UAV) monitoring device based on intelligent control. Background Art

[0002] With the rapid development of drone technology, drones have been widely used in environmental monitoring, agriculture, surveying and mapping, search and rescue, and other fields. In particular, in environmental monitoring, drones can be equipped with various sensors to collect aerial data, providing important information support for scientific research and decision-making.

[0003] However, in outdoor environments, drone camera surfaces are inevitably susceptible to various sources of contamination. For applications requiring high-precision visual data, lens stains can severely impact mission performance. Existing drone designs often offer limited options for cleaning cameras. Some high-end models may be equipped with simple baffles or shields to reduce contamination, but these measures don't completely address the problem, especially after extended flights or when operating in harsh environments.

[0004] Existing drone sampling devices are relatively limited in functionality, typically only collecting samples for a specific type of substance (such as air or water), lacking the ability to integrate multiple functions.

DETAILED DESCRIPTION

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] Example:

[0040] like Figures 1 to 7As shown, a drone monitoring device based on intelligent control includes a drone body 1 and a camera module 2. The drone body 1 adopts an existing four-rotor drone, and the camera module 2 is set on the drone body 1.

[0041] Specifically, a camera mounting plate 11 is rotatably provided on the lower side of the drone body 1, and a pitch control mechanism 3 is provided between the camera mounting plate 11 and the drone body 1. The pitch control mechanism 3 can use an existing pitch control motor to drive the camera mounting plate 11 to perform pitch motion. A turntable 12 is rotatably provided on the upper end of the camera mounting plate 11, and the camera module 2 is fixedly provided on the turntable 12. The outer side of the turntable 12 is provided with teeth. A first motor 13 is fixedly provided on the camera mounting plate 11, and a pinion 14 that meshes with the teeth is provided on the output shaft of the first motor 13. The pinion 14 is driven to rotate by the first motor 13, thereby driving the toothed disc 12 and the camera module 2 on the toothed disc 12 to rotate, thereby achieving multi-angle shooting. Preferably, the camera module 2 adopts a visual recognition camera.

[0042] In order to prevent the camera module 2 from being stained after long-term outdoor work, a sliding rod frame 21 is horizontally arranged at the front end of the camera module 2. A vertically arranged cleaning brush 22 is slidably connected to the sliding rod frame 21. The cleaning brush 22 moves horizontally back and forth along the sliding rod frame 21 to clean the camera module 2.

[0043] To drive the reciprocating motion of the cleaning brush 22, a rotating rod 23 is rotatably mounted on the upper end of the camera module 2. A hollow column 24 is coaxially fixed to the rotating rod 23. A reciprocating cam groove 25 is provided on the hollow column 24. The upper end of the cleaning brush 22 is connected to a cam pusher 26 via a connecting bar, which engages with the reciprocating cam groove 25. Rotating the rotating rod 23 drives the hollow column 24 to rotate, which in turn drives the cleaning brush 22 along the slide frame 21 through the interaction of the reciprocating cam groove 25 and the cam pusher 26.

[0044] One end of the rotating rod 23 is connected to a first bevel gear 27. A connecting plate 15 is provided at the upper end of the camera module 2. A rotating shaft is rotatably mounted on the connecting plate 15. The lower end of the rotating shaft is fixedly connected to a second bevel gear 28 that meshes with the first bevel gear 27. The upper end of the rotating shaft is fixedly connected to a planetary gear 29. A fixing plate 16 is provided on the upper side of the camera module 2. This fixing plate 16 is fixed relative to the camera mounting plate 11. A center gear 17 that meshes with the planetary gear 29 is fixedly connected to the fixing plate 16. When the turntable 12 rotates the camera module 2, it drives the planetary gear 29 in orbit. Due to the meshing of the planetary gear 29 with the center gear 17, the planetary gear 29 rotates, which in turn drives the second bevel gear 28 to rotate, causing the first bevel gear 27, the rotating rod 23, and the hollow column 24 to rotate.

[0045] Preferably, two rotating rods 23 , two hollow columns 24 , and two cleaning brushes 22 are each provided, and the two rotating rods 23 are symmetrically arranged. One end of the two rotating rods 23 close to each other is provided with a first bevel gear 27 meshing with the second bevel gear 28 .

[0046] The drone body 1 is also provided with an air sampling device 4 and a water sampling device 5. The air sampling device 4 is used to collect air samples, and the water sampling device 5 is used to collect water samples.

[0047] Specifically, the air sampling device 4 includes a sampler 41, a sampling tube 42 and a lifter 43. The lifter 43 is arranged at the upper end of the drone body 1, and the sampling tube 42 is arranged on the lifter 43. When sampling is required, the air inlet of the sampling tube 42 is lifted to a certain height by the lifter 43 to reduce the air disturbance caused by the rotor of the drone body to the sampling area and ensure the quality of air sampling.

[0048] The lifter 43 can be a scissor-type lifter made of lightweight materials. Specifically, it includes multiple groups of scissor rods hinged in sequence, wherein a return spring 411 is provided between two support rods 410 of one or more groups of scissor rods. Through the elastic force of the return spring 411, the scissor-type lifter is in an extended state when not affected by external force.

[0049] A second motor 412 and a drum 413 are mounted on the upper end of the drone body 1. The motor shaft of the second motor 412 is connected to the drum 413. A steel wire rope 414 is wound around the drum 413, one end of which is connected to a hinge shaft 415 of one of the scissor lifts. To retract the scissor lift, the second motor 412 drives the drum 413 to rotate, pulling the steel wire rope 414 to retract the scissor lift.

[0050] The sampler 41 includes a sampling box, a first piston 44, a second piston 45, and a drive mechanism 46. Both the first and second pistons 44, 45 are slidably disposed within the sampling box. The first piston 44 is sealed against the inner wall of the sampling box, forming a sampling chamber 47 for storing sampled air. The second piston 45 is also sealed against the sampling box. Together with the first piston 44 and the sampler box, the second piston 45 forms a decontamination chamber 48, which is used to aspirate air initially present in the sampling tube 42, minimizing interference with the sampled air.

[0051] Specifically, the first piston 44 and the second piston 45 are connected by a telescopic rod 49, and the driving mechanism 46 drives the second piston 45 to move along the sampling box. The telescopic stroke of the telescopic rod 49 is smaller than the movement stroke of the second piston 45. The upper end of the sampling tube 42 is the air inlet, and the lower end of the sampling tube 42 is connected to the sampling chamber 47 and the impurity removal chamber 48 through a branch pipe.

[0052] The driving mechanism 46 first drives the second piston 45 to move, so that the volume of the impurity removal chamber 48 increases, and the air in the sampling tube 42 is sucked into the impurity removal chamber 48; when the telescopic rod 49 reaches the maximum telescopic stroke, it pulls the first piston 44 to move, so that the volume of the sampling chamber 47 increases, and the air in the sampling area is sucked into the sampling chamber 47 through the sampling tube 42, thereby realizing air sampling.

[0053] Preferably, the driving mechanism 46 is a linear motor.

[0054] In order to ensure the safety of the drone body 1 during flight, the drone should try to avoid contact with the water surface when sampling water sources. In this embodiment, the water source sampling device 5 includes a sampling barrel 51 and a water pipe 52. The sampling barrel 51 is fixedly arranged at the lower end of the drone body 1 and is used to store water samples. A gear ring 53 is rotatably provided on the upper end of the sampling barrel 51, and the water pipe 52 is arranged on the gear ring 53 and multiple water pipes 52 are arranged along the circumference of the gear ring 53; the gear ring 53 is connected to a rotary driver 54. When the gear ring 53 rotates, it drives the water pipe 52 to rotate, and then water is introduced into the sampling barrel 51 through the water pipe 52 to achieve sampling. In this way, only the lower end of the water pipe 52 needs to be in contact with the water surface, reducing the interference of the water surface on the drone.

[0055] Preferably, a ring 55 is provided at the lower end of the ring gear 53. A lifting controller 56 is provided between the ring 55 and the ring gear 53. A guide ring 57 is rotatably provided on the ring 55. A support rod I 58 is rotatably provided on the ring gear 53, and a support rod II 59 is rotatably provided on the guide ring 57. The water conduit 52 is hingedly connected to support rods I 58 and II 59, respectively. The lifting controller 56 controls the distance between the ring 55 and the ring gear 53, thereby adjusting the angle of the water conduit 52. When water sampling is not required, the water conduit 52 can be rotated upward to prevent interference with the ground when the drone body 1 lands.

[0056] Preferably, the lower end of the drone body 1 is connected to a support leg 6, a shock absorber rod 61 is hinged on the outer side of the support leg 6, a wheel is provided at the lower end of the shock absorber rod 61, and a spring damper 62 is hinged between the shock absorber rod 61 and the support leg 6. When the drone body 1 lands, the lower end of the shock absorber rod 61 contacts the ground and slides, and the impact is absorbed by the spring damper 62.

[0057] To control the drone monitoring device, it also includes a control module 7, a drive module, and a communication module. Both the drive module and the communication module are electrically connected to the control module 7. The drive module is electrically connected to the pitch control mechanism 3, the first motor 13, the air sampling device 1, and the water sampling device 5. The communication module is electrically connected to a server or terminal. The control module 7, the drive module, and the communication module are all existing modules.

[0058] The above only describes in detail the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the scope of protection of the present invention.
