DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] See also Figure 1-Figure 8 A drone low-altitude photography device for ground survey includes a camera 11 located below a drone body 1, two brackets 2 are fixedly connected to the bottom surface of the drone body 1, the camera 11 is located between the two brackets 2, a support column 4 is fixedly connected to the bottom surface of the drone body 1, a shell 3 is fixedly connected to the bottom surface of the support column 4, a shooting port 301 is penetrated through one side of the shell 3, the camera 11 is located inside the shell 3, and the front end of the camera 11 is directly opposite to the shooting port 301, a rotating mechanism is connected to one side of the shell 3, a transparent glass ring 5 is connected to one end of the rotating mechanism close to the camera 11, the outer wall of the transparent glass ring 5 is slidably connected to the inner wall of the shooting port 301, a cleaning component is connected to the outer wall of the shell 3, the cleaning component is abutted against the outer wall of the transparent glass ring 5, and an optical glass cleanliness detection sensor 12 is fixedly connected to the side of the camera 11 close to the shooting port 301.

[0029] The low-altitude photography device of an unmanned aerial vehicle for ground survey in the utility model is similar to the structure of an existing unmanned aerial vehicle, such as a unmanned aerial vehicle disclosed in the patent with the announcement number CN216186079U. Figures 1 to 8 As shown, the drone low-altitude photography device for ground survey in the utility model is controlled to fly the drone body 1 by remote control or by setting the ground survey photography route in advance during normal use. During the flight, if dust or mosquitoes are attached to the transparent glass ring 5 of the shell 3, the optical glass cleanliness detection sensor 12 senses that the line of sight is blocked, and transmits an electrical signal to the internal processor of the drone body 1, and starts the rotating mechanism through the controller. After the rotating mechanism is started, it drives the transparent glass ring 5 to rotate inside the shell 3, so that the clean part of the transparent glass ring 5 originally located inside the shell 3 can be turned to the outside of the shell 3, and continue to cooperate with the camera 11 to perform the shooting task.

[0030] When the transparent glass ring 5 rotates, it will contact the cleaning component located at the connection between the shooting port 301 and the outer shell 3, and then the dust or mosquitoes adhering to the surface of the transparent glass ring 5 will be cleaned by the cleaning component. When the transparent glass ring 5 needs to be rotated again, the transparent glass ring 5 that is rotated again can still be clean and clear.

[0031] It is also necessary to explain that the optical glass cleanliness detection sensor 12 is a sensor capable of detecting surface cleanliness, and is usually a reflective photoelectric sensor or an infrared sensor. Its working principle is to use the light beam or infrared beam emitted by the sensor to measure the intensity of the reflected or transmitted light on the surface of the object being tested, thereby achieving the purpose of detecting the surface cleanliness.

[0032] Please refer to Figure 6 and Figure 7 The cleaning assembly includes a support plate 9 and cleaning cotton 15. The outer walls at both ends of the support plate 9 are respectively connected to the two sides of the outer wall of the shell 3. One side of the support plate 9 is fixedly connected to the cleaning cotton 15, and the other side of the cleaning cotton 15 is against the outer wall of the transparent glass ring 5.

[0033] More specifically, under normal circumstances, the transparent glass ring 5 is against the cleaning cotton 15, and when the transparent glass ring 5 rotates, the surface of the transparent glass ring 5 is against the cleaning cotton 15, so the dust or mosquitoes adhering to the surface of the transparent glass ring 5 can be wiped off, and because the cleaning cotton 15 and the support plate 9 are located below the outer shell 3, they will not affect the shooting of the camera 11.

[0034] Please refer to Figure 3-Figure 8 A water tank 7 is fixedly connected to one side of the support plate 9 away from the cleaning cotton 15 , and a pumping mechanism is connected to the inside of the water tank 7 , and an output end of the pumping mechanism is connected to the support plate 9 .

[0035] More specifically, by arranging a water tank 7 behind the support plate 9 and arranging a pumping mechanism inside the water tank 7, when the transparent glass ring 5 rotates, the cleaning liquid can be extracted from the inside of the water tank 7 by the pumping mechanism and transported to the cleaning cotton 15, thereby facilitating the cleaning of the transparent glass ring 5 by the cleaning cotton 15.

[0036] Please refer to Figure 7 The pumping mechanism includes a water pump 16 and a water pipe 17. A plurality of water outlet holes 901 are formed on one side of the support plate 9 close to the cleaning cotton 15. The outer wall of the water pump 16 is fixedly connected to the bottom surface of the inner wall of the water tank 7. The output end of the water pump 16 is fixedly connected to one end of the water pipe 17. The other end of the water pipe 17 penetrates the water tank 7 and the support plate 9 and is connected to the plurality of water outlet holes 901.

[0037] More specifically, when the optical glass cleanliness detection sensor 12 detects that dust or mosquitoes are stuck on the surface of the transparent glass ring 5, affecting the shooting clarity, the internal controller of the drone body 1 starts the rotating mechanism, and the transparent glass ring 5 rotates driven by the rotating mechanism. At the same time, the controller turns on the switch of the water pump 16. After the water pump 16 is started, water is sucked from the inside of the water tank 7 and transported from the water pipe 17 to the inside of the support plate 9. Then, the water enters the cleaning cotton 15 through a number of water outlet holes 901, thereby soaking the cleaning cotton 15, and thus the transparent glass ring 5 can be cleaned faster and more efficiently.

[0038] Please refer to Figure 3-Figure 5 A sealing cover 8 is threadedly connected to one side of the upper end of the water tank 7.

[0039] More specifically, by providing the sealing cover 8, the water filling port of the water tank 7 can be sealed.

[0040] Please refer to Figure 8 Both ends of the support plate 9 are fixedly connected with mounting blocks 18, and the two mounting blocks 18 are fixedly connected to the housing 3 by bolts.

[0041] More specifically, by setting up the mounting block 18 and connecting them through bolts, the connectivity between the support plate 9, the water tank 7 and the outer shell 3 can be increased, making it difficult for them to be separated from each other; and after the drone body 1 completes the mission and returns, the cleaning cotton 15 can also be cleaned or replaced by removing the bolts.

[0042] Please refer to Figure 5 and Figure 6 The rotating mechanism includes a rotating motor 6 and a rotating plate 10. The outer wall of the rotating motor 6 is fixedly connected to the inner wall of the outer shell 3. The output shaft of the rotating motor 6 is fixedly connected to the inner wall of the rotating plate 10. The side of the rotating plate 10 away from the rotating motor 6 is fixedly connected to one side of the transparent glass ring 5.

[0043] More specifically, when the optical glass cleanliness detection sensor 12 detects that dust or mosquitoes are stuck on the surface of the transparent glass ring 5, affecting the shooting clarity, the internal controller of the drone body 1 turns on the switch of the rotating motor 6. After the rotating motor 6 is started, it drives the rotating plate 10 to rotate, and then the transparent glass ring 5 can be driven to rotate through the rotating plate 10.

[0044] Please refer to Figure 6 A swing motor 14 is fixedly connected to the inner wall of the housing 3 away from the rotating motor 6 , and the output shaft of the swing motor 14 is fixedly connected to the outer wall of the camera 11 .

[0045] More specifically, by providing a swing motor 14, when the drone body 1 performs a shooting task, the up and down angle adjustment of the camera 11 can be achieved through the swing motor 14 to shoot a wider angle.

[0046] Please refer to Figure 6 and Figure 7 The inner wall of the housing 3 is provided with a drying chamber 302 , the inner wall of the drying chamber 302 is fixedly connected with a water-absorbing cloth 13 , and the outer wall of the water-absorbing cloth 13 abuts against the outer wall of the transparent glass ring 5 .

[0047] More specifically, by providing a drying chamber 302 and an absorbent cloth 13, after the surface of the transparent glass ring 5 is cleaned with the soaked cleaning cotton 15, the water stains can be absorbed by the absorbent cloth 13, thereby preventing water from entering the outer shell 3 and causing damage to the camera 11 inside the outer shell 3 or the optical glass cleanliness detection sensor 12.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
