A remote control water sample collection device for monitoring polluted water bodies

Abstract

The invention discloses a remote control type water sample collecting device for monitoring contaminated water. The device comprises a mainframe box. A plurality of independent monitoring chambers areformed inside the mainframe box through partition plates, a power battery is fixedly installed inside the middle monitoring chamber, a plurality of independent USB electric interfaces are arranged onthe power battery, a remote control system and a sampling control system are arranged inside the monitoring chambers on the two sides, and the two ends of the mainframe box are each fixedly providedwith a retractable stabilizing device; a propeller is installed on the side face of the mainframe box through a driving plate, the bottom of the mainframe box is in an inverted concave shape, a vertical landing gear for water sampling is fixedly installed at the inverted concave shape, and the edges of the bottom of the mainframe are each provided with a water inflation air bag; remote control canbe achieved, the device is applicable to various water regions, sampling can be performed for different water depths, the device is provided with various fixed point structures, and meanwhile the device has the capabilities of fixed point sampling and movable sampling.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a remote control water sample collection device for monitoring polluted water bodies. Background technique [0002] As an important part of environmental monitoring, water quality monitoring refers to the programmed process of sampling, measuring, recording or sending out signals for various characteristic indicators of water in order to grasp the water environment quality and the dynamic changes of pollutants in the water system. The accuracy of water quality monitoring largely depends on water quality monitoring sampling. The quality of sampling depends largely on the sampling location and sampling method. [0003] As we all know, even in the same water area, different sampling points and sampling methods will eventually obtain different sampling results, and even large deviations will occur. Moreover, for some special monitoring projects, it is necessary to ...

AI Technical Summary

Problems solved by technology

[0006] (1) Existing sampling devices often take samples directly, and then analyze the samples later in the laboratory to obtain parameters. However, for some conventional parameters such as the number of bacteria, pH value, etc., the parameters will change in a closed container, affecting Final monitoring results;

[0007] (2) There are defects in the layout of the monitoring system, which cannot be directly controlled remotely, and cannot take into account fixed-point monitoring and mobile monitoring at the same time when laying out, and there are also major defects in the depth sampling of water areas, which cannot satisfy sampling at any depth ;

[0008] (3) There are certain requirements for the water environment. For waters where aquatic plants multiply or other pollutants, because it will affect the normal operation of the drive mechanism and sampling device, the remote sampling device will no longer be applicable, and it can only be collected manually, and artificially go deep into the water. Direct sampling will also cause the above problems;

[0009] (4) The existing floating-point monitoring stations cannot be fixed at the same location for a long time, and are easily affected by various factors on the water surface, which will eventually affect the monitoring results at the same location. As a result, its accuracy is not up to the requirement
