Embodiment

[0023] Such as figure 1 , 2 shown. The UAV pod used for environmental sample collection of the present invention includes a UAV control system and a sample collection device suspended on the UAV, and the sample collection device includes a pod housing and a load placed in the pod housing. A pressure sampler, the negative pressure sampler has a collection arm 6 extending out of the pod housing, under the negative pressure of the negative pressure sampler, the sample is sucked into the negative pressure sampling tube through the collection arm 6 .

[0024] The negative pressure sampler includes: a turntable 3, a drive mechanism of the turntable 3, a collection needle 4 arranged at the center of the turntable 3, and a plurality of negative pressure sampling tubes 2 distributed radially around the turntable 3 with the collection needle 4 as the center. The collection needle 4 is installed on the upper end of the collection arm 6; when the turntable 3 rotates a gear every time, t...

Abstract

The invention discloses an unmanned aerial vehicle pod for environmental sample collection and a collection method. The unmanned aerial vehicle pod comprises an unmanned aerial vehicle control system and a sample collection device hung on an unmanned aerial vehicle. The sample collection device comprises a pod shell and a negative pressure sampler arranged in the pod shell. The negative pressure sampler is provided with a collection arm stretching out of the pod shell. Under the negative pressure effect of the negative pressure sampler, samples are pumped into a negative pressure sampling pipe through the collection arm. The unmanned aerial vehicle pod has the advantages of being simple in structure, light, convenient and flexible to control and the like; a plurality of identical or different samples can be collected through one time of flight of the unmanned aerial vehicle; the defects that the power of an existing sampler is supplied by a sampling pump, and the existing sampler is complicated in structure and inflexible in control are overcome; mechanical faults are greatly reduced, the load borne by the unmanned aerial vehicle is lowered, and sample collection is more accurate, more economical and easier.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle sampling device, in particular to an unmanned aerial vehicle pod and an acquisition method for collecting environmental samples. Background technique [0002] With the emphasis on environmental pollution in modern society and the continuous strengthening of research on environmental pollution, the demand for environmental sample collection continues to increase. Traditional environmental sample collection is mainly divided into on-site collection and fixed-point sample collection. These two collection methods have their own advantages and disadvantages. The former has high flexibility, but the cost of manpower and time is high, and the collection accuracy is low. Although the latter has high collection accuracy, it has a large fixed investment. At the same time, this collection method requires land and continuous maintain. For ordinary scientific research teams, the cost of these two sample collecti...
