High-precision telescopic water area stratified sampling device for water quality monitoring

Abstract

The invention discloses a high-precision telescopic water area stratified sampling device for water quality monitoring. The device comprises a floating seat, a first sampling cylinder, a second sampling cylinder, a water storage bin and a scraping blade, a driving impeller is arranged on the side surface of the floating seat, a second reel is fixed at the upper end of a rotating shaft through a bolt, and a movable plate sleeves the outer side of the upper end of the rotating shaft; and a limiting hole is formed in the side face of the movable plate, a limiting block is arranged on the outer side of the inner wall of the water storage bin, a reset spring is connected between the limiting block and the water storage bin, and a second pull rope is connected between the floating plate and thesecond winding wheel. The high-precision telescopic water area stratified sampling device for water quality monitoring is provided with the multiple telescopic first sampling cylinder and second sampling cylinder, water samples of different depths in different water areas can be quantitatively collected, the sampling efficiency and precision are high, meanwhile, a filter screen mechanism can be automatically cleaned, blockage of the sampling mechanism is avoided, and operation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a high-precision telescopic water quality monitoring water area layered sampling device. Background technique [0002] With the continuous development of science and technology and economy, the degree of industrialization is getting higher and higher, but the ensuing environmental pollution problems are becoming more and more serious, especially water pollution, which will seriously affect people's daily life and water ecology. Environmental balance, so water quality monitoring is very important. Through water quality monitoring, the type, concentration and change trend of pollutants in the corresponding waters can be accurately detected, so as to facilitate the subsequent evaluation of water quality and purification treatment. In the process of water quality monitoring It is often necessary to use a water body sampling device for sampling, but there are still so...
