A sampling and detection UAV for open water

Abstract

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, comprising an unmanned aerial vehicle main body and a retractable and unwinding module, wherein the retracting and unwinding module is assembled on the unmanned aerial vehicle main body; The lower end of the group is equipped with a sampling module for collecting bottom mud, and the retractable module is used to adjust the position of the sampling module; the sampling module includes: a casing, which is fixed on the lower end of the retractable module; a sampling mechanism is assembled in the The casing is used for collecting sediment samples; the sample storage box is fixed on the lower end of the casing, and a plurality of partition plates are arranged inside the sample storage box. The present invention enables the device to collect a variety of sediment samples in one trip, avoids the frequent return of the drone, improves the collection efficiency, and reduces the collection cost, and the device can collect the remaining sediment samples after each sampling is completed. Rinse is performed to avoid affecting the samples collected subsequently, and the accuracy of the 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 it 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 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, they accumulate in the sediment. Various organic and inorganic pollutants in the sediment re-enter the overlying water through the physical, chemical and biological exchange with the overlying water, becoming a secondary pollutio...

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
