Stratified sampling device for detecting water quality and producing and sampling methods for stratified sampling device

Abstract

The invention relates to a stratified sampling device for detecting the water quality and aims at providing the stratified sampling device for detecting the water quality, which has high detection accuracy and detection efficiency and can carry out sampling detection on water with different depths. For solving the technical problem, the invention provides the stratified sampling device for detecting the water quality; the stratified sampling device comprises a sampling box, separation boards, springs, baffles, connecting rods, rotating shafts, a stay wire, a pulley and the like, wherein the pulley is arranged at the middle of the top of the sampling box; a reel is arranged at the right end of the top of the sampling box; a hand crank is arranged on the front side of the reel; the stay wireis wound on the reel; at least two separation boards are arranged in the sampling box at uniform intervals; the sampling box is divided into at least three cavities by the separation boards. The stratified sampling device disclosed by the invention samples the water with the different depths and has high sampling efficiency; manual operation is adopted and a large amount of labor force and material resources are saved.

Description

technical field [0001] The invention relates to a layered sampling device for water quality detection, in particular to a layered sampling device for water quality detection and its manufacturing and sampling methods. Background technique [0002] Water is the source of life. Human beings cannot do without water in their daily life and production activities. The quality of drinking water is closely related to human health. With the development of society and economy, the progress of science and the improvement of people's living standards, people's requirements for the quality of drinking water have been continuously improved, and the standards for drinking water quality have also been continuously developed and improved accordingly. Since the establishment of drinking water quality standards is related to many factors such as people's living habits, culture, economic conditions, scientific and technological development level, water resources and their water quality status, ...
