Unmanned aerial vehicle loaded automatic water sampling device

Abstract

The invention relates to an unmanned aerial vehicle loaded automatic water sampling device. The unmanned aerial vehicle loaded automatic water sampling device consists of a sampling device frame, a sample collecting and storage box, a water pump, a water quality detector and a system controller, wherein a camera capable of rotating circularly is arranged on the bottom of the sampling device frame;the sample collecting and storing box consists of a stepping motor a, a reel, a reeling rope, a sample storing bottle, a deionized water box, a sampling bottle and a pressure sensor; the stepping motor a controls the reel to rotate, and drags the reeling rope to control the falling height of the sampling bottle; after the sampling bottle enters water, the sampling depth is fed back by the pressure sensor; during layered sampling, the sampling bottle is placed in water at first until water depth displayed by the pressure sensor is not changed, the water of the lower layer is sampled while thewater depth is recorded, and the sampling depths of the upper layer and the middle layer are determined according to the water depth, and samples of the corresponding layers are collected. Compared with the prior art, the unmanned aerial vehicle loaded automatic water sampling device has the advantages that samples can be collected in a layered manner at multiple points in a large range.

Description

technical field [0001] The invention relates to the field of water quality sampling equipment, in particular to an automatic water quality sampler carried by an unmanned aerial vehicle. Background technique [0002] With the rapid economic development and the improvement of people's living standards, the pollution of water resources is becoming more and more serious. Water pollution control and water ecological restoration are imminent. Water sample collection and investigation are the premise and key of pollution control and ecological restoration. At present, there are mainly two methods for water quality sampling: (1) Manual sampling, using simple sampling bottles for manual sampling. This method requires samplers to take boats to the water body for sampling. The sampling efficiency is low and there are certain risks; (2) Sampling by automatic sampling equipment generally takes sampling at fixed monitoring stations. Although this method can perform stratified sampling, it...

At present, there are mainly two methods for water quality sampling: (1) Manual sampling, using simple sampling bottles for manual sampling. This method requires samplers to take boats to the water body for sampling. The sampling efficiency is low and there are certain risks; (2) Sampling by automatic sampling equipment generally takes sampling at fixed monitoring stations. Although this method can perform layered sampling, it can only sample one point and cannot satisfy large-scale multi-point sampling

After searching the Chinese patent literature, the application number: 201710877883.8 announced a water quality automatic sampler, which provides a sampler with a simple structure and multiple samples, but the sampling bottle has no cover plate, and it is easy to be polluted during deep sampling, which affects the quality of the sample. Accuracy; and there is no sampling depth perception function, it is impossible to accurately locate the sampling depth

In addition, the existing water quality samplers do not have the functions of water quality detection and real-time transmission
