step 3, at the moment, a sampling gear set is driven by a sampling motor to rotate, a sampling screw rod is driven to rotate, a sampling gasket is driven to move upwards, a water source is extracted, the water source enters a sampling vessel along a sampling hose, at the moment, a lifting shaft is driven by a lifting cylinder to move downwards along a lifting guide rod, a vessel clamp is driven to move downwards, the sampling vessel is separated from a sampling pump, at the moment, the telescopic shaft is driven by the telescopic cylinder to move telescopically along the telescopic guide rod, the front and back positions of the vessel clamp are adjusted, the sampling vessel and the sampling pump are staggered, at the moment, the lifting shaft is driven by the lifting cylinder to move upwards along the lifting guide rod, the vessel clamp is driven to move upwards, the sampling vessel is separated from the sampling hose, at the moment, the water source is blocked by a one-way valve, the phenomenon of water source sprinkling is further prevented, at the moment, the vessel conversion device works, the sampling vessel is placed in the original position, and the sampling work of the water source is further completed;
step 4, because the dish-changing device is arranged to rotate the sampling utensils, the dish-changing rotating shaft drives the dish-changing plate to rotate, and further drives the dish-changing fastener to rotate, so as to drive the sampling utensils to rotate, and further convert the sampling utensils storing the water source, and further, when the sampling unmanned aerial vehicle is not needed to sample the same water source at multiple points, the sampling unmanned aerial vehicle can sample the water source repeatedly;
step 5, after the sample was accomplished, because the water source of sample will increase the sample and prevent sinking unmanned aerial vehicle's gravity, provide ascending buoyancy by floating the board this moment, and then offset the weight at partial sample water source, and then prevent that the sample from preventing sinking unmanned aerial vehicle from appearing in the sample in-process and sinking the phenomenon.
