Unmanned aerial vehicle for water sample collection

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, particularly relates to an unmanned aerial vehicle for water sample collection, and provides the following scheme for solving the problems in the prior art: the unmanned aerial vehicle comprises a machine shell, wings are arranged at four corners of the machine shell, a controller is arranged in the machine shell, a rack is arranged on the outer wall of the bottom of the machine shell, and a collection barrel is arranged below the machine shell; the bottom face of the collection barrel is of a spherical surface structure, a middle barrel is fixedly connected to the inner wall of the bottom of the collection barrel, at least six annularly and evenly distributed partition plates are fixedly connected between the outer wall of the side face of the middle barrel and the inner wall of the side face of the collection barrel, and a collection cavity is reserved between every two partition plates. A middle shell penetrating through the machine shell is arranged on the inner wall of the side face, located on the middle cylinder, of the machine shell, and a pressure lifting mechanism is arranged in the middle shell. The unmanned aerial vehicle prevents impurities such as duckweed on the water surface from influencing water sample collection, can ensure that no large impurities exist in the collected water sample, and facilitates subsequent cleaning.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle for collecting water samples. Background technique [0002] With the rapid development of society, people pay more and more attention to environmental protection issues, and the environmental monitoring and protection of water resources is the most important among them. The collection of water samples in water areas is an important task in the monitoring of water resources and environment. In the past, it was necessary to charter a boat to drive to various locations in the water area, manually throw the water collector into the water for water sample collection, and then transport the collected water samples back to the At the shore workstation, the staff will conduct water quality testing on water samples. [0003] However, this water quality sampling method has problems such as inconvenience, low efficiency, and inaccurate sampling p...

AI Technical Summary

Problems solved by technology

[0003] However, this water quality sampling method has problems such as inconvenience, low efficiency, and inaccurate sampling positions. Therefore, in the prior art, UAVs are usually used for water sample collection. The existing collection method is usually suspended under the UAV. The sampling cylinder controls the drone to fly above the sampling point, and then controls the drone to descend and make the sampling cylinder enter the water for sampling. However, in some lakes, there are usually a large number of aquatic plants and floating discs floating on the water surface. When sampling, the sampling cylinder will not be able to enter the water for sampling due to the influence of aquatic plants and other debris, making sampling extremely inconvenient
