Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) detection technology, specifically a multi-angle adjustable gimbal device for UAV remote sensing detection. Background Technology

[0002] In today's era of rapid technological development, UAV remote sensing technology has been widely used in many fields such as geological exploration, environmental monitoring, agricultural surveying, and disaster assessment due to its significant advantages such as high efficiency, flexibility, and wide coverage.

[0003] An existing patent (publication number: CN222040737U) discloses a high-altitude inspection drone for geological exploration, belonging to the field of drones. It includes a drone body; a drone frame mounted at the bottom of the drone body, the drone frame comprising: two vertical poles connected to the drone body, the distance between the two vertical poles gradually increasing from top to bottom; a horizontal bar positioned at the bottom of the two vertical poles; and a main unit housing positioned between the two vertical poles, one end of which is equipped with a camera, and elastic limiting members on both sides of the main unit housing for elastically pulling and retracting the two vertical poles. The beneficial effect of this application is that it provides good buffering and stress relief during landing, improving the overall durability of the drone.

[0004] However, due to the significant temperature difference between high altitudes and the ground, drones move up and down with the terrain during missions. Temperature changes at different altitudes can easily cause fogging and condensation on the camera surface. When fog forms on the camera surface, the fog adheres to the lens, severely affecting light transmission and causing a significant decrease in the clarity of the captured image. This results in poor image data quality, failing to accurately reflect the true situation of the target area, and consequently affecting subsequent data analysis and decision-making. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a multi-angle adjustable gimbal device for UAV remote sensing detection, which has advantages such as defogging and easy adjustment, and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a multi-angle adjustable gimbal device for UAV remote sensing detection, including a UAV body, a gimbal assembly at the bottom of the UAV body, a camera below the gimbal assembly, and the gimbal assembly being used to adjust the illumination area of ​​the camera.

[0007] The camera is equipped with a defogging component at its bottom. The defogging component includes a support frame, which is fixedly connected to the bottom of the camera. A storage frame is provided at the front end of the support frame. The storage frame is arranged along the length of the drone body. A rotating tube is rotatably connected to the storage frame along its length. A spray box is fixedly connected to the rotating tube. An air outlet is fixedly connected to the top of the spray box. The top of the air outlet is inclined. A heating wire module is installed inside the spray box.

[0008] The defogging assembly also includes a frame fixedly connected to the bottom of the spray box. The frame is set along the height direction of the drone body, and an adhesive strip is fixedly connected to the side of the frame close to the drone body.

[0009] Furthermore, the defogging assembly also includes a drive motor, the output end of which is fixedly connected to one end of the rotating tube.

[0010] Through the above scheme, the drive motor can provide power for the rotation of the rotating tube, enabling the frame and spray box to rotate according to the set requirements, thereby realizing the automated operation of defogging and scraping functions.

[0011] Furthermore, the defogging assembly also includes an air pump, which is fixedly connected to one side of the storage frame;

[0012] The defogging assembly also includes a set of circumferentially arranged air inlet slots on the surface of the rotating tube, an air inlet cylinder is rotatably connected to the outer surface of the rotating tube, the set of air inlet slots are all located inside the air inlet cylinder, and the output end of the air pump is fixedly connected to the air inlet cylinder.

[0013] Through the above scheme, the air pump can draw in external air and enter the rotating tube through the air inlet cylinder and air inlet slot, and finally blow it out from the air outlet pipe, providing airflow power for defogging. At the same time, it works with the heating wire module to heat the airflow, which acts on the surface of the camera lens to effectively remove fog and condensation on the lens.

[0014] Furthermore, the gimbal assembly includes a first motor, which is fixedly installed at the bottom of the drone body. A connecting rod is fixedly connected to the output end of the first motor. A second motor is installed at the bottom end of the connecting rod. An adjustment frame is fixedly connected to the output end of the second motor. Rotary shafts are rotatably connected to the two inner side walls of the adjustment frame. The camera is located between the two rotating shafts and fixedly connected to them. A third motor is installed on one side of the adjustment frame, and the output end of the third motor is fixedly connected to one end of its corresponding rotating shaft.

[0015] Through the above scheme, the first motor, the second motor and the third motor work together to enable the camera to be adjusted at multiple angles in three-dimensional space, meeting the needs of different shooting angles and directions, and improving the flexibility and accuracy of remote sensing detection.

[0016] Furthermore, the first motor is positioned along the height direction of the UAV body, and the connecting rod is positioned along the height direction of the UAV body.

[0017] With the above scheme, the first motor drives the connecting rod to rotate around the height of the drone body, thereby causing the camera below to rotate in a circle, realizing the adjustment of the shooting angle of the camera in the horizontal direction.

[0018] Furthermore, the second motor is arranged along the length of the UAV body, and the adjustment frame is also arranged along the length of the UAV body.

[0019] The above method allows the second motor to drive the adjustment frame to rotate around the length of the drone body, thereby tilting the camera and adjusting the shooting angle.

[0020] Furthermore, the third motor is arranged along the width direction of the UAV, and both rotating shafts are arranged along the width direction of the UAV body, with the two rotating shafts being coaxial.

[0021] The above scheme uses a third motor to drive the rotating shaft to rotate, which in turn causes the camera to rotate around the width of the drone body, thereby adjusting the camera's rotation around the shaft and thus its pitch angle.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This multi-angle adjustable gimbal device for UAV remote sensing detection uses a defogging component installed at the bottom of the camera connected to the gimbal assembly at the bottom of the UAV body. The defogging component uses an air pump to draw in external air, which is heated by a heating wire module and then blown onto the camera lens through an air outlet pipe. At the same time, a drive motor drives a rotating tube to rotate, causing the frame and rubber strip to scrape the lens surface. This effectively removes fog and condensation from the camera lens surface, ensuring the clarity of images captured by the camera in complex temperature environments and ensuring that the acquired image data accurately reflects the true situation of the target area.

[0024] In addition, the first, second, and third motors in the gimbal assembly work together to enable multi-angle adjustment of the camera in three-dimensional space, meeting the needs of different shooting angles and directions, and further improving the flexibility and accuracy of remote sensing detection.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Please see Figures 1-8 This embodiment of a multi-angle adjustable gimbal device for UAV remote sensing detection includes a UAV body 1, a gimbal assembly 2 at the bottom of the UAV body 1, and a camera 3 below the gimbal assembly 2. The camera 3 is a multispectral camera, specifically model MS600PRO. The gimbal assembly 2 is used to adjust the illumination area of ​​the camera 3.

[0040] The gimbal assembly 2 includes a first motor 201, which is fixedly mounted on the bottom of the UAV body 1. A connecting rod 202 is fixedly connected to the output end of the first motor 201. A second motor 203 is mounted on the bottom end of the connecting rod 202. An adjustment frame 204 is fixedly connected to the output end of the second motor 203. Rotating shafts 205 are rotatably connected to the two inner sidewalls of the adjustment frame 204. A camera 3 is located between the two rotating shafts 205 and fixedly connected to them. A third motor 206 is mounted on one side of the adjustment frame 204. The output end of the third motor 206 is fixedly connected to one end of its corresponding rotating shaft 205. The first motor 201, second motor 203, and third motor 206 cooperate to achieve multi-angle adjustment of the camera 3 in three-dimensional space, meeting the needs of different shooting angles and directions, and improving the flexibility and accuracy of remote sensing detection. The first motor 201 moves along the bottom of the UAV body 1. The drone body 1 is positioned along its height, and the connecting rod 202 is also positioned along its height. The first motor 201 drives the connecting rod 202 to rotate around the height of the drone body 1, thereby causing the camera 3 below to rotate in a circle, thus adjusting the shooting angle of the camera 3 in the horizontal direction. The second motor 203 is positioned along the length of the drone body 1, and the adjustment frame 204 is also positioned along the length of the drone body 1. The second motor 203 drives the adjustment frame 204 to rotate around the length of the drone body 1, thereby causing the camera 3 to tilt and adjust the shooting angle. The third motor 206 is positioned along the width of the drone, and both rotating shafts 205 are also positioned along the width of the drone body 1 and are coaxial. The third motor 206 drives the rotating shafts 205 to rotate, causing the camera 3 to rotate around the width of the drone body 1, thus adjusting the camera 3's rotation around the axis and adjusting its pitch angle.

[0041] A defogging component 4 is installed at the bottom of the camera 3. The defogging component 4 includes a support frame 401, which is fixedly connected to the bottom of the camera 3. A storage frame 402 is provided at the front end of the support frame 401. The storage frame 402 is set along the length of the drone body 1. The storage frame 402 is rotatably connected to a rotating tube 403, which is set along its length. The rotating tube 403 is fixedly connected to a spray box 404. An air outlet pipe 405 is fixedly connected to the top of the spray box 404. The top of the air outlet pipe 405 is inclined, and the air outlet of the air outlet pipe 405 faces the lens of the camera 3 so as to blow the heated gas onto the lens surface, effectively helping to remove fog and condensation on the lens. A heating wire module 406 is installed inside the spray box 404. The heating wire module 406 is existing technology. It generates heat by passing current through a resistance wire, which can quickly heat the gas and provide a heat source for defogging.

[0042] The defogging assembly 4 also includes a frame 407 fixedly connected to the bottom of the spray box 404. The frame 407 is set along the height direction of the drone body 1. An adhesive strip 408 is fixedly connected to the side of the frame 407 near the drone body 1. During use, when the condensation fog is severe, the frame 407 is rotated by driving the rotating tube 403 to scrape the surface of the camera lens 3, quickly removing a large amount of condensation and fog. Then, heated gas is blown out through the air outlet tube 405 to further remove residual moisture. The adhesive strip 408 is made of rubber. Due to the softness and elasticity of the adhesive strip 408, the lens surface will not be damaged when scraping the lens, while effectively removing moisture.

[0043] The defogging assembly 4 also includes a drive motor 409, the output end of which is fixedly connected to one end of the rotating tube 403. The drive motor 409 provides power for the rotation of the rotating tube 403, enabling the frame 407 and the spray box 404 to rotate according to set requirements, thus automating the defogging and wiping functions. The defogging assembly 4 also includes an air pump 410, which is fixedly connected to one side of the storage frame 402. The defogging assembly 4 also includes a set of circumferentially arranged openings on the surface of the rotating tube 403. The air inlet slot 411 is rotatably connected to the air inlet cylinder 412 on the outer surface of the rotating tube 403. A set of air inlet slots 411 are all located inside the air inlet cylinder 412. The output end of the air pump 410 is fixedly connected to the air cylinder. The air pump 410 can draw in external air and enter the rotating tube 403 through the air inlet cylinder 412 and the air inlet slot 411, and finally blow it out from the air outlet pipe 405, providing airflow power for defogging. At the same time, it works with the heating wire module 406 to heat the airflow, which acts on the surface of the camera lens 3, effectively removing fog and condensation on the lens.

[0044] The working principle of the above embodiment is as follows: When there is condensation and fog on the screen, the air pump 410 is started. The air pump 410 draws in external air, which enters the rotating tube 403 through the air inlet cylinder 412 and the air inlet slot 411. The airflow entering the rotating tube 403 continues to flow to the spray box 404. The top of the spray box 404 is fixedly connected to the air outlet pipe 405. The spray box 404 is equipped with a heating wire module 406. The heating wire module 406 generates heat by passing current through the resistance wire, which quickly heats the airflow entering the air outlet pipe 405. The heated gas is blown out at an angle from the top of the air outlet pipe 405. The air outlet of the air outlet pipe 405 faces the lens of the camera 3, blowing the heated gas toward the lens surface to help remove fog and condensation on the lens.

[0045] When condensation or fog is severe, the drive motor 409 starts, and its output end is fixedly connected to one end of the rotating tube 403. The drive motor 409 provides power for the rotation of the rotating tube 403. The rotation of the rotating tube 403 drives the frame 407 fixedly connected to the bottom of the spray box 404 to rotate. The side of the frame 407 close to the drone body 1 is fixedly connected to the adhesive strip 408. The adhesive strip 408 is made of rubber and has softness and elasticity. When condensation or fog is severe, the rotation of the frame 407 drives the adhesive strip 408 to scrape the surface of the camera lens 3, quickly removing a large amount of condensation and fog. Then, heated gas is blown out through the air outlet 405 to further remove residual moisture. The softness and elasticity of the adhesive strip 408 ensure that the lens surface will not be damaged when scraping the lens, while effectively removing moisture.
