Long-endurance fixed-point fixed-depth quantitative intelligent water quality sampling unmanned aerial vehicle

Abstract

The invention relates to a long-endurance fixed-point fixed-depth quantitative intelligent water quality sampling unmanned aerial vehicle which comprises an unmanned aerial vehicle body, a water sample collecting device is installed on the unmanned aerial vehicle body and comprises a roller, a water taking pipe and a plurality of sampling bottles, the water taking pipe is wound on the roller, and a roller motor is installed on the side face of the roller; the roller motor is suitable for driving the roller to rotate, one end of the water taking pipe is communicated with an inner cavity of the roller, a liquid level transmitter is installed at the other end of the water taking pipe, a connector is arranged on the side face of the roller, an extension pipe is connected to an external port of the connector and communicated with the inner cavity of the roller, and a peristaltic pump is connected to the extension pipe. And the tail end of the extension pipe is connected with a plurality of split charging pipes. According to the device, the cruising ability of the unmanned aerial vehicle is improved, and accurate fixed-point and fixed-depth collection can be realized according to water sample collection technical regulations. Water samples at multiple point positions can be collected at a time, real-time water sample collection amount information is obtained, the standardization and accuracy of water sample collection are guaranteed, and the water collection efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles and water sample collection, in particular to a long-duration fixed-point fixed-depth quantitative intelligent water quality sampling unmanned aerial vehicle. Background technique [0002] At present, the field of water quality monitoring in my country mainly relies on manual monitoring and automatic sampling. They all have their own limitations. Manual monitoring requires a lot of preparations in the early stage. The sampling period is long and the work efficiency is low. It is difficult to reach the designated sampling location, which requires a lot of manpower and material resources; unmanned ship monitoring will hinder and pollute the unmanned ship when the water surface is seriously polluted or there are a large number of floating objects, and the collection work cannot be completed; the use of drones to carry out Compared with the traditional manual sampling and automatic samp...

[0002] At present, my country's water quality monitoring field mainly relies on manual monitoring and automatic sampling methods. They all have their own limitations. Manual monitoring requires a lot of preparation in the early stage, the sampling period is long, and the work efficiency is low. It is difficult to reach the designated sampling location, which requires a lot of manpower and material resources; unmanned ship monitoring, when the water surface is seriously polluted or there are a lot of floating objects, the unmanned ship will also be hindered and polluted, and the collection work cannot be completed; Compared with traditional manual sampling and automatic sampling methods, water quality sampling not only has the advantages of high efficiency and high personnel safety, but also has a wide range of drone operations and strong mobility, which can meet the needs of large-scale inspections and can penetrate into dangerous areas. , can be sampled in complex environments or places that are difficult for people and ships to reach

[0003] Existing sampling UAVs have a short battery life, consume energy for round trips, and cannot work efficiently. The weight of the UAV itself will also increase the energy consumption of the fuselage and reduce the stability of sampling.
