Stratified water quality sampling device facilitating detection of water areas of different sections

Abstract

The invention discloses a stratified water quality sampling device facilitating detection of water areas of different sections. The stratified water quality sampling device comprises a water quality sampling box, a vertical electric telescopic rod, a propeller and a motor, three sampling lattices remain inside the water quality sampling box, the vertical electric telescopic rod is fixed to the upper portion of the water quality sampling box, the upper portion of the vertical electric telescopic rod is connected to a horizontal electric telescopic rod through a connection shaft, the inner sideof the propeller is connected to the water quality sampling box through a rotary shaft, the motor is rotatably connected to the outer side of the propeller, and a paddle is installed at the outer endof the propeller. In the stratified water quality sampling device facilitating the detection of the water areas of the different sections, the independent sampling lattices are arranged in the water quality sampling box, water quality which is sampled three times can be collected at one time, mutual infection among different kinds of water quality can be avoided, at the same time, the water areasat different positions and at the same height can be sampled three times at one time, then data of three-time sampling is analyzed and compared, and accordingly the precision of water quality detection is improved.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a water quality layered sampling device for convenient detection of water areas in different sections. Background technique [0002] Environmental monitoring is an important basis for environmental protection and management. Nowadays, more and more people are concerned about the quality of their environment. Therefore, environmental monitoring is particularly important. Environmental monitoring mainly includes air testing, soil testing and water quality. There are three major aspects of detection. With the improvement of industrial level, a large amount of sewage is discharged randomly, which has caused great pollution to water quality. If people eat these polluted water by mistake, it will cause great harm to the body. Therefore, water quality detection It is imminent, but the existing water quality testing is not convenient for three-dimensional movement of the...

Problems solved by technology

[0003] The purpose of the present invention is to provide a water quality layered sampling device that is convenient for detecting waters in different sections, so as to solve the problem that the existing water quality detection in the above background technology is not convenient for three-dimensional movement of the water quality sampling box during the detection process, and most of the sampling The device only samples the same water area once, which reduces the diversity of sampling. At the same time, when stratified sampling is performed on the same water area, the sampled water quality cannot be well separated, resulting in mutual infection between the sampled water quality, thus The problem of reducing the accuracy of water quality testing
