Unmanned aerial vehicle water body fixed-point sampling device

Abstract

The invention discloses an unmanned aerial vehicle water body fixed-point sampling device, and belongs to the technical field of water quality monitoring. The unmanned aerial vehicle water body fixed-point sampling device comprises an unmanned aerial vehicle body and a sampler, wherein the sampler comprises a sampling bottle and a bottle sleeve, the bottle sleeve is connected with the unmanned aerial vehicle body through a traction rope, a bottle cap pulled by a floating ball is arranged at the bottle opening of the sampling bottle, the floating ball is connected with the bottle cap through aconnecting wire, the length of the connecting wire is equal to the sampling depth of the sampling bottle, a reset mechanism is further installed on the bottle cap, and the bottle cap covers the bottleopening through the reset mechanism after the sampling bottle is filled. According to the invention, the floating ball pulls the bottle cap of the sampling bottle to be opened, so that the sampling bottle can start to contain water; the connecting wire of the floating ball is the sampling depth, so that fixed-point sampling is achieved; and the bottle cap is provided with the reset mechanism, andafter a water sample is taken, the reset mechanism can cover with the bottle cap, so that the water in the sampling bottle cannot be mixed with water in other areas, and the sampling accuracy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to an unmanned aerial vehicle water body fixed-point sampling device. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. The scope of monitoring is very wide, including unpolluted and polluted natural water (river, river, lake, sea and groundwater) and various industrial drainage. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, chromaticity, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand and biochemical oxygen demand etc.; the other category is some toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury and organ...
