Technical Field

The utility model relates to the field of water quality monitoring, in particular to a water sample collection device for water quality monitoring.

Background

The water quality monitoring is a process of monitoring and measuring the types of pollutants in the water body, the concentrations and the variation trends of various pollutants and evaluating the water quality condition. The water quality monitoring range is very wide, including uncontaminated and contaminated rivers, lakes, seas, underground water and the like, and water quality needs to be detected by using equipment of a detection room, so that a sampling bottle needs to be used for sampling before detection. In order to improve the accuracy of detection, it is usually necessary to sample from a position far from the bank of rivers, lakes, seas or underground water.

For sampling, a sampling person needs to sit on a ship far away from the shore, and sampling is difficult in a remote place without the ship. And the nearer to the middle part of river, lake, sea or groundwater, the degree of depth of surface of water is great, has certain danger when the personnel of taking a sample keep away from the bank, in order to improve the security, generally needs two at least people on the ship, and when taking a sample, when one of them takes a sample, another person need control the ship, avoids the ship out of control, so the personnel of taking a sample that need are also more.
