Embodiment Construction

[0011] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] by Figure 1 to Figure 5 Given that the present invention includes an outer shell 1 and an inner shell 2. The outer shell 1 and the inner shell 2 are both vertical quadrangular prism structures, and the inner shell 2 is installed in the outer shell 1 and can be in the outer shell 1. Sliding up and down, the inner shell 2 is attached to the outer shell 1, a first compression spring 3 is installed between the bottom of the inner shell 2 and the outer shell 1, and the top of the outer shell 1 is provided with a first through hole 4 and connected with a hanging rope 5 There is a first water inlet 6 on the left side wall of the outer shell 1, and the inner shell 2 is divided into a plurality of water storage chambers 8 by a plurality of horizontal partitions 7 evenly distributed up and down. There is a second water inlet 9 on the t...

Abstract

The invention relates to a stratified sampling device for water quality monitoring, and effectively solves the problems that the stratified sampling of a water body needs multiple operations, and a water sample is easy to mix. According to the technical scheme, the device comprises an outer shell and an inner shell, the inner shell is mounted in the outer shell and can slide up and down in the outer shell, and a first pressure spring is arranged between the bottoms of the inner shell and the outer shell; a first water inlet is formed on the left side wall of the outer shell, the interior of the inner shell is divided into a plurality of water storage chambers by a plurality of horizontal partition plates which are uniformly distributed up and down, and a second water inlet is formed at thetop of the left side wall of each water storage chamber; an elastic block capable of popping up inwards is installed on the right side wall of the outer shell, a vertical sliding groove is formed onthe right side wall of each water storage chamber, the depths of the multiple sliding grooves are decreased progressively from top to bottom according to an arithmetic progression, and the inner end of the elastic block can extend into the sliding grooves. According to the present invention, the sampling operation frequency is greatly reduced, the electromagnetic valve control is not needed, the timely sealing can be achieved after sampling, and the problem of the mixing of the water samples with different depths is solved.

Description

Technical field [0001] The invention relates to the field of water quality monitoring, in particular to a layered sampling device for water quality monitoring. Background technique [0002] Water quality sampling is an important part of water quality monitoring. It is required to accurately extract water samples at specific time and spatial locations; when sampling deep water, it is often necessary to sample multiple depths according to the depth gradient. Currently, when performing stratified sampling, Generally, a water intake container is lowered to a specified depth, and a cover plate that can be opened and closed in one direction is provided on the water intake container. It is opened during lowering and closed during lifting, so as to realize sampling work. This method has many drawbacks: Only one depth of sample can be taken at a time. When stratified sampling, the container needs to be lowered for sampling; second, the cover is opened during the lower process, water enter...
