Sampling detection unmanned aerial vehicle applied to open water area

Abstract

The invention belongs to the technical field of unmanned aerial vehicles, and particularly relates to a sampling detection unmanned aerial vehicle applied to an open water area, the sampling detection unmanned aerial vehicle comprises an unmanned aerial vehicle main body and a retractable module, and the retractable module is assembled on the unmanned aerial vehicle main body; a sampling module for collecting bottom mud is assembled at the lower end of the collecting and releasing module, and the collecting and releasing module is used for adjusting the position of the sampling module; the sampling module comprises a shell fixed at the lower end of the retractable module; the sampling mechanism is assembled on the shell and is used for collecting a bottom mud sample; the sample storage box is fixed to the lower end of the shell, and a plurality of partition plates are arranged in the sample storage box. According to the device, various bottom mud samples can be collected through one-time voyage, frequent return voyage of the unmanned aerial vehicle is avoided, the collection efficiency is improved, the collection cost is reduced, and after each time of sampling, the device can flush bottom mud left inside, so that the influence on subsequently collected samples is avoided, and the accuracy of sample detection results is improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a sampling and detection unmanned aerial vehicle applied to open waters. Background technique [0002] Sediment is the sediment of rivers and lakes, and is an important part of natural waters. In the process of pollution control of rivers and lakes, sediment pollution control is one of the main difficulties, and it is also a relatively common environmental problem. There is a dynamic balance of absorption and release between the water body and the sediment. When the water body is seriously polluted, some pollutants can enter the sediment through precipitation and adsorption; when the pollution caused by external sources is controlled, the accumulation in the Various organic and inorganic pollutants in the sediment re-enter the overlying water body through physical, chemical, and biological exchanges with the overlying water body, becoming a secondary ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional technology, before the treatment of vast waters such as rivers and lakes, most of them need to rely on manual boats to reach the sampling waters, and the sampling personnel dive to sample the sediment at the bottom of the waters. In the existing technology, in order to avoid the existence of However, in the existing technology, drones can only collect one type of sediment sample at a time, and frequent return flights are required. The sampling efficiency of sediment is slow, and the sampling cost is relatively high. High, based on the above problems, there is an urgent need for a sampling and detection drone used in open waters to efficiently sample sediment
