Throwing type liquid taking device based on unmanned aerial vehicle platform

Abstract

The invention provides a throwing type liquid taking device based on an unmanned aerial vehicle platform. The throwing type liquid taking device comprises an unmanned aerial vehicle and a throwing type liquid taking device. The unmanned aerial vehicle comprises an unmanned aerial vehicle main frame and a grabbing device. The grabbing device comprises a telescopic rod, a mechanical claw and a rotating rod. The throwing type liquid taking device mainly comprises a floater, an outer frame, a liquid collecting bin, a buffering balance weight bin, a wire box and other auxiliary components. Comparedwith traditional manual sampling, the device has the advantages that the labor cost of single sampling is low, and the real-time performance of samples is high; compared with an unmanned aerial vehicle sampling device for long-time hovering extraction sampling, the device has the advantages that the requirements for the balance capacity, cruising power, loading capacity and other performance of an unmanned aerial vehicle are low, the structure is simple, the device manufacturing cost is low, and the representativeness of taken samples is high. Meanwhile, according to the throwing type structural design, only the liquid taking device needs to be thrown down, the liquid taking device is clamped at a throwing point at certain intervals, the process is simple, the requirement for the performance of the unmanned aerial vehicle is not high, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a throwing-type liquid-taking device based on an unmanned aerial vehicle platform. Background technique [0002] The detection of water quality usually requires quantitative sampling in different water areas and different water depths. At present, the conventional sampling method is to carry positioning equipment and take manual sampling on water vehicles. The sampling tool is generally a portable peristaltic pump. The sampling process is cumbersome and consumes a lot of manpower and material resources. UAV sampling has the advantages of high work efficiency, strong real-time performance, and cost-saving sampling, and its application in water sample collection has attracted more and more attention. At present, the use of UAVs for water sample collection is a popular research, but most of the research is biased towards long-term hovering of UAVs to take samples, ...

AI Technical Summary

Problems solved by technology

[0006] However, the above-mentioned hovering extraction sampling device has the following defects: the UAV needs to be kept at a certain fixed height to ensure the accuracy of the sample collection height during the sampling operation, but with the accumulation of samples, the weight of the UAV It will gradually increase, so the UAV needs to constantly adjust its self-generated balance ability, which requires high control and adjustment performance of the UAV; and the fluidity of the liquid is strong. The shaking of the drone, and the drone is not easy to hover for a long time in the case of strong wind and waves on the water surface

At the same time, drones also need to carry waterproof electromagnetic equipment, which increases the load of drones and increases the cost of drone protection and maintenance.
