Abstract

The invention relates to a deep water body sampling device for water quality monitoring, and effectively solves the problems that 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 housing and an inner housing which are sleeved. A pressure spring is mounted at the bottom of the inner housing; a through hole is formed in the upper side wall of the outer housing; the inner housing is internally divided into a plurality of water storage chambers which are circumferentially distributed; awater inlet hole is formed in the top of each water storage chamber; a plurality of vertical plungers in one-to-one correspondence with the water inlet holes are fixed at the top end of the inner wall of the outer housing; an annular groove is formed in each plunger; the annular grooves in the multiple plungers are different in height, and the heights of the multiple annular grooves are distributed in an arithmetic progression; elastic blocks capable of popping up leftwards are installed on the right side wall of the outer housing; a plurality of clamping grooves which are vertically and evenly distributed are formed in the outer wall of the right side of the inner housing; and the right ends of the elastic blocks can be popped into the clamping grooves. The sampling operation frequency is greatly reduced, electromagnetic valve control is not needed, timely sealing can be achieved after sampling, and the problem of mixing of water samples in different depths is solved.

Description

technical field [0001] The invention relates to the field of water quality monitoring, in particular to a deep water body sampling device for water quality monitoring. Background technique [0002] Water quality sampling is an important part of water quality monitoring, and 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 designated depth, and the water intake container is provided with a cover plate that can be opened and closed in one direction, which is opened during the lowering process and closed during the lifting process, so as to realize the sampling work. There are many disadvantages in this method: First, every Only one depth sample can be taken at a time, and the container needs to be lowered multiple times for sampling...
