The invention discloses an amphibious sampling detection unmanned aerial vehicle. The amphibious sampling detection unmanned aerial vehicle comprises a central control box, a sampling box, support legs, propellers and a sampling
pipe, a plurality of support legs are extended to the periphery of the side face of the center control box in the horizontal direction, propellers are mounted on the upperparts of the support legs, the sampling box is arranged at the bottom of the central control box, the sampling box is provided with a sampling
pipe downwards, the lower end of the sampling
pipe is immersed in water during sampling, and the sampling box collects
water quality samples through the sampling pipe in a suction manner and is stored in the sampling pipe. The sampling box comprises a box,a pipe rack, a plurality of sample pipes and a joint, the pipe rack is arranged in the box, the sample pipes are arranged on the pipe rack, the sample pipes are connected with the sampling pipe through the joint, the sample pipe is initially in a
vacuum state, and the sample pipes collect
water quality samples through the sampling pipe in a vacuum suction manner. By using the vacuum of each sample pipe itself as the power during sampling, the traditional mechanical pump is not used as a
water sampling power, the weight of the unmanned aerial vehicle is greatly reduced, the flight is rapid, and the structure is simple.
