Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping unmanned aerial vehicles, in particular to an aerial photography device for geographic surveying and mapping. Background Art

[0002] Geographic surveying is the most important task in field investigation. Currently, geographic surveying is mainly carried out using drones. The remote control of the control terminal is used to remotely control the drone to fly above the destination, take aerial photos of the destination and its surrounding areas, and remotely transmit the captured images back to the control terminal to achieve the effect of geographic surveying.

[0003] At present, the camera of the existing UAV for geographic surveying and mapping is generally installed on the belly of the UAV. When adjusting the shooting angle through the gimbal, the height of the camera cannot be changed and is easily blocked by the landing gear. Therefore, it is necessary to frequently change the flight direction for surveying and mapping shooting. In addition, the landing gear needs to frequently contact the ground, resulting in rapid wear and damage of the landing gear, which can easily cause the UAV to fall to the ground and roll over, resulting in damage to the camera and loss of surveying and mapping data. Therefore, there is an urgent need for an aerial photography device for geographic surveying and mapping to solve the above problems. Utility Model Content

[0031] In this embodiment, in actual use, the second motor 14 is started to make the worm 15 drive the worm wheel 16 to rotate, and the worm wheel 16 drives the transmission shaft 8 to rotate. The transmission shaft 8 uses the transmission slider 13 to drive the transmission sleeve 9 to rotate, so that the shooting direction of the camera 7 can be adjusted.

[0032] Among them, a rotating slider 17 is fixedly connected to the side wall of the rotating part 4, and an annular groove is opened inside the lifting plate 3.
