[0019] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described.

[0020] Embodiment

[0021] Please refer to Figures 1-4 , the present invention provides a technical solution: an unmanned aerial vehicle photography sampling device for environmental detection, including a photography frame 1. An auxiliary component for protecting the sampling lens is arranged outside the photography frame 1. The auxiliary component includes a positioning groove 2 arranged at the front end of the photography frame 1 for positioning the angle of the light-transmitting flexible plate 4 when passing through the photography frame 1. An annular frame 3 is arranged outside the photography frame 1. The annular frame 3 is sleeved outside the photography frame 1 to avoid obstruction when the unmanned aerial vehicle conducts environmental detection on a water source. A debris discharge hole 301 is arranged at the bottom of the annular frame 3 for discharging the impurities swept from the light-transmitting flexible plate 4 through the annular frame 3 when the cleaning tool is used. A through groove 5 is arranged inside the annular frame 3. A light-transmitting flexible plate 4 is arranged inside the through groove 5. The light-transmitting flexible plate 4 can be located at the front end of the picture sampling lens, thereby isolating the lens from the external environment and avoiding direct contact between the impurities in the external environment and the lens to protect the lens.

[0022] A plurality of cavities 6 are arranged on the inner wall of the through groove 5. Springs 601 and support plates 602 are arranged inside each of the plurality of cavities 6. The springs 601 are used to support the support plates 602 and push them out of the cavities 6 so that they extend into the through groove 5. When the light-transmitting flexible plate 4 passes and abuts against the cleaning tool and is pressed, the support plates 602 can contract to provide a space for the light-transmitting flexible plate 4 to pass through. Brushes 7, scrapers 8, and cleaning pads 9 are respectively arranged on the support plates 602 inside the plurality of cavities 6 in sequence according to the conveying path. When impurities or rain and snow adhere to the outside of the light-transmitting flexible plate 4 due to extreme environments, the light-transmitting flexible plate 4 rotates to circulate inside the annular frame 3. When the light-transmitting flexible plate 4 rotates inside the annular frame 3, the impurities attached to the light-transmitting flexible plate 4 can be cleaned by sequentially passing through the brushes 7, scrapers 8, and cleaning pads 9 to keep the light-transmitting flexible plate 4 clean and permeable.

[0023] In this embodiment, all electrical components are controlled by a conventional controller.

[0024] Embodiment, please refer to Figures 1-4, the positioning groove 2 runs through the inside of the camera stand 1, and the two ends respectively correspond to the openings of the annular frame 3. The annular frame 3 is clamped on the outer wall of the camera stand 1 and is connected to the outer wall of the camera stand 1 by bolts. A filter screen is installed on the inner wall of the impurity discharge hole 301 at the bottom of the annular frame 3 to isolate impurities below the camera stand 1. The light-transmitting flexible plate 4 runs through the annular frame 3 and is slidably connected to the through groove 5 of the annular frame 3. The positioning groove 2 is located at the front end of the image acquisition lens of the camera stand 1. When the light-transmitting flexible plate 4 in the annular frame 3 passes through the positioning groove 2, it is also in front of the acquisition lens and isolates the lens from the outside. A plurality of the cavities 6 are annularly distributed on the inner wall of the through groove 5. Both ends of the spring 601 are respectively connected to the inner wall of the cavity 6 and the support plate 602 by welding. One end of the support plate 602 is located in the cavity 6 and is slidably connected to the inner wall of the cavity 6, and the other end extends into the through groove 5 by the push of the spring 601. The brush 7, the scraper 8, and the cleaning pad 9 are respectively connected to the support plates 602 at different positions of the cavities 6 by bolts. When the light-transmitting flexible plate 4 rotates in the through groove 5, it sequentially passes through the brush 7, the scraper 8, and the cleaning pad 9. During use, first, the camera stand 1 is installed on the drone by bolts, and the drone is flown to drive the camera stand 1 to fly at the water source for environmental detection. While photographing and sampling the environment, the PLC controller is used to control the light-transmitting flexible plate 4 to continuously rotate in a cycle in the annular frame 3 and the positioning groove 2 at the front end of the camera stand 1 to isolate the sampling lens. When impurities or rain and snow adhere to the light-transmitting flexible plate 4 due to extreme environments, the area with adhered impurities is driven by the rotation of the light-transmitting flexible plate 4 into the annular frame 3, and at the same time, the cleaned area is extended to protect the lens. When the area with adhered impurities moves in the through groove 5, the spring 601 in the cavity 6 pushes the support plate 602 to extend towards the through groove 5, and the cleaning tool is pushed to abut against the light-transmitting flexible plate 4. After the light-transmitting flexible plate 4 sequentially passes through the brush 7, the scraper 8, and the cleaning pad 9, the light-transmitting flexible plate 4 is cleaned and recycled by rotation.

[0025] The working process of the utility model is as follows: When in use, first install the photography stand 1 on the drone through bolts, and drive the photography stand 1 to fly at the water source for environmental detection by the flight of the drone. While conducting photography sampling of the environment, the PLC controller is used to control the light-transmitting flexible plate 4 to continuously rotate in a cycle in the positioning groove 2 at the front ends of the annular frame 3 and the photography stand 1, and isolate the sampling lens. When impurities or rain and snow adhere to the light-transmitting flexible plate 4 due to extreme environments, the area with adhered impurities is driven by the rotation of the light-transmitting flexible plate 4 into the annular frame 3, and at the same time, the cleaned area is extended to protect the lens. When the area with adhered impurities moves in the through groove 5, the spring 601 in the cavity 6 pushes the support plate 602 to extend towards the through groove 5, and pushes the cleaning tool to abut against the light-transmitting flexible plate 4. After the light-transmitting flexible plate 4 passes through the brush 7, the scraper 8 and the cleaning pad 9 in sequence, the light-transmitting flexible plate 4 is cleaned and recycled through rotation. The utility model realizes the isolation and protection of the drone photography lens, and through the cyclic rotation of the light-transmitting plate used for isolation, cleaning is carried out while rotating, continuously maintaining a transparent effect, avoiding the lens picture being covered by impurities, and improving the imaging effect of picture sampling.
