Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of unmanned aerial vehicle (UAV) technology, and more specifically, to a surveying UAV. Background Technology

[0002] Due to terrain factors and with the advancement of technology, drones are now used for aerial surveying. Drone aerial surveying is a powerful supplement to traditional aerial photogrammetry. Drones equipped with cameras take aerial photos at high altitudes and transmit the captured images to a computer via wireless transmission devices. The computer then uses software and hardware to generate a 3D view of the photographed objects. Drone aerial surveying is accomplished through cameras.

[0003] When existing surveying drones are used for surveying in cold winters, the low outside temperature and the heat generated by the drones themselves can cause the cameras to be affected by temperature differences.

[0045] like Figures 1-4As shown, this invention discloses a surveying drone according to one embodiment, including a drone body 1, a camera 2 mounted on the bottom of the drone body 1, and further including: a connecting box 3, a protective cover 4, a defogging mechanism, and a cleaning rod 5. The side of the cleaning rod 5 that contacts the protective cover 4 is made of rubber, and the protective cover 4 is made of transparent glass. The connecting box 3 is fixedly connected to the bottom of the drone body 1, the camera 2 is mounted on the bottom of the connecting box 3, and the protective cover 4 is fixedly connected to the bottom of the connecting box 3. The camera 2 is located inside the protective cover 4, which can protect the camera 2. Through the cooperation between the connecting box 3, the protective cover 4, the defogging mechanism, the rotating mechanism, and the cleaning rod 5, it is easy to eliminate fog on the camera 2, greatly reducing the impact of fog on the camera 2, and can clean fog and impurities on the outer surface of the transparent cover, thereby improving the efficiency and effect of surveying.

[0046] The defogging mechanism is located inside the connecting box 3 and can disperse fog on the protective cover 4 and camera 2. The defogging mechanism includes: an air inlet cylinder 6, an air intake fan 7, a heating component, and an air outlet component. The connecting box 3 has two air inlets, and the air inlet cylinder 6 is fixedly connected to the two air inlets. The air intake fan 7 is installed at the bottom of the air inlet cylinder 6, and the output end of the air intake fan 7 faces inward towards the protective cover 4, enabling it to deliver outside air into the protective cover 4. The heating component is located inside the air inlet cylinder 6 and can heat the air entering the air inlet cylinder 6. The air outlet component is located inside the connecting box. Inside 3, hot air inside the protective cover 4 can be discharged. The heating component includes: heater 8 and heating wire 9. An installation rod 15 is fixedly connected inside the air inlet cylinder 6. The heater 8 is installed on one side of the installation rod 15 and at one end of the air inlet cylinder 6. The heating wire 9 is connected to the heater 8. The air outlet component includes: air outlet pipe 10 and air outlet fan 11. Two air outlet holes are opened on the connecting box 3. The air outlet pipe 10 is fixedly connected to the two air outlet holes. The air outlet fan 11 is installed at one end of the air outlet pipe 10. The output end of the air outlet fan 11 faces outward from the connecting box 3.

[0047] The heater 8 installed inside the air intake 6 controls the heating wire 9 to heat the air entering the air intake 6. The heated air is then blown into the protective cover 4 by the air intake fan 7 installed inside the air intake duct, changing the temperature of the protective cover 4 and the camera 2, thereby eliminating the fog inside the protective cover 4 and on the camera 2. Then, the hot air inside the protective cover 4 is discharged through the air outlet fan 11 installed inside the air outlet pipe. This cycle ensures the temperature inside the protective cover 4 and improves the clarity of the camera 2.

[0048] The cleaning rod 5 is mounted at the bottom of the connecting box 3 via a rotating mechanism for cleaning the outer surface of the protective cover 4. The rotating mechanism includes a gear ring 12 and a drive assembly. The gear ring 12 is rotatably connected to the bottom of the connecting box 3, and the cleaning rod 5 is fixedly connected to the bottom of the gear ring 12. The cleaning rod 5 contacts the outer surface of the protective cover 4. The drive assembly is located at the bottom of the connecting box 3 and can drive the gear ring 12 to rotate. The drive assembly includes a drive gear 13 and a first motor 14. A mounting bracket 16 is fixedly connected to one side of the connecting box 3. The first motor 14 is mounted at the bottom of the mounting bracket 16. The drive gear 13 is located at the bottom of the connecting box 3 and meshes with the gear ring 12. The output end of the first motor 14 is fixedly connected to the drive gear 13.

[0049] The first motor 14 drives the drive gear 13 to rotate. When the drive gear 13 rotates, it drives the gear ring 12 to rotate. When the gear ring 12 rotates, it drives the cleaning rod 5 to rotate on the surface of the protective cover 4, thereby scraping off and cleaning the fog and impurities on the surface of the protective cover 4.

[0050] The working principle is as follows: During flight mapping in cold winter, the heater 8 installed inside the air intake 6 controls the heating wire 9 to heat the air entering the air intake 6. The heated air is then blown into the protective cover 4 by the air intake fan 7 installed inside the air intake duct, changing the temperature of the protective cover 4 and the camera 2, thereby eliminating fog inside the protective cover 4 and on the camera 2. Then, the hot air inside the protective cover 4 is discharged through the air outlet fan 11 installed inside the air outlet pipe. This cycle ensures the temperature inside the protective cover 4 and improves the clarity of the camera 2. At the same time, the first motor 14 drives the drive gear 13 to rotate. When the drive gear 13 rotates, it drives the gear ring 12 to rotate. When the gear ring 12 rotates, it drives the cleaning rod 5 to rotate on the surface of the protective cover 4, thereby scraping off and cleaning the fog and impurities on the surface of the protective cover 4, thus improving the efficiency and effectiveness of flight mapping.
