An unmanned aerial vehicle for collecting water samples

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, especially a kind of unmanned aerial vehicle for collecting water samples. Aiming at the problems existing in the prior art, the following proposals are proposed, including the casing, the four corners of the casing are equipped with wings, and the four corners of the casing are equipped with wings. A controller is installed inside, a rack is installed on the bottom outer wall of the casing, and a collection cylinder is arranged under the casing, and the bottom surface of the collection cylinder is a spherical structure, the bottom inner wall of the collection cylinder is fixedly connected with an intermediate cylinder, and the side of the intermediate cylinder There are at least six annular partitions evenly distributed between the outer wall and the side inner wall of the collection cylinder, and a collection chamber is left between every two partitions. The side inner wall of the casing above the middle cylinder is provided with a The middle shell, and the inside of the middle shell is provided with a pressure-lifting mechanism. The invention prevents duckweed and other debris on the water surface from affecting the collection of water samples, and at the same time ensures that there are no large pieces of debris in the collected water samples, which 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
