Description

Technical Field

[0001] The utility model belongs to the technical field of unmanned aerial vehicle mobile platforms, and specifically relates to an unmanned aerial vehicle remote sensing measurement mobile platform. Background Art

[0002] In engineering surveys, in order to obtain detailed remote sensing data of a certain area, drones are often used to collect remote sensing data of low-altitude areas. Due to the limited flight distance and control range of drones, drones are often transported to the area to be measured during actual surveys, and launched into the air using a dedicated drone launcher. The remote sensing data measured by the drone is collected through dedicated receiving equipment. Most of the drones are now transported directly by freight trucks. At present, the existing technology of drone remote sensing measurement mobile platform for engineering surveys, after transporting the drone to the area to be measured, needs to be charged because the drone is used for a long time and the battery is exhausted.

[0003] For example, Chinese utility model CN218316427U discloses a mobile platform for remote sensing measurement of unmanned aerial vehicles. The placement table is placed on the top of a vehicle, the positioning plate is placed on the bottom of the vehicle, the positioning frame is moved, and the position of the positioning frame is fixed by bolts. At this time, the card plate is against the bottom of the vehicle, and the card plate drives the spring to compress. The fixing performance is increased by the pressure of the spring, and the moving plate is moved to a suitable position. The electromagnetic suction cup is started by the control box to suck on the vehicle to fix the position of the placement table. The unmanned aerial vehicle is placed on the top of the placement table. After moving the moving frame to a suitable position, the position of the moving frame is fixed by bolts, and the motor is started to drive the connecting block to descend. The connecting block drives the fixing frame to descend. At this time, the soft pad is pressed on the pole at the bottom of the unmanned aerial vehicle to fix the position of the unmanned aerial vehicle.

[0004] Although the above-mentioned prior art can make the drone more stable when docked, when the vehicle is parked in an uneven location, the body of the vehicle will also tilt to one side, and the drone is easy to fall when docked, resulting in damage to the drone. Utility Model Content
