Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, in particular to a water quality sampling device for monitoring river and lake water environments. Background Art

[0002] Environmental monitoring refers to the activities of environmental monitoring agencies to monitor and measure environmental quality. Environmental monitoring is carried out by monitoring and measuring indicators that reflect environmental quality to determine the level of environmental pollution and environmental quality. The content of environmental monitoring mainly includes the monitoring of physical indicators, chemical indicators, and ecosystems. Environmental monitoring is the basis for scientific management of the environment and environmental law enforcement supervision, and is an essential basic work for environmental protection. The core goal of environmental monitoring is to provide data on the current status and changing trends of environmental quality, judge environmental quality, and evaluate current major environmental issues. Water quality testing is one of the most important projects in environmental monitoring. Through water testing, the level of environmental quality around the water source can be determined, and whether the water source is polluted.

[0003] After searching, the Chinese patent announcement number: CN214200824U discloses a water quality sampler for environmental monitoring, which relates to the field of water conservancy engineering technology. The utility model includes a support mechanism, a counterweight mechanism, a sliding mechanism, a rotating mechanism and a sampling mechanism. The counterweight mechanism is fixedly connected to the support mechanism, the counterweight mechanism is fixedly connected to the sliding mechanism, the sliding mechanism is movably connected to the rotating mechanism, and the sampling mechanism is connected to the support mechanism through a traction rope. The sliding mechanism includes a movable part and a movable groove provided on the movable part. Both ends of the movable part are provided with mounting holes, and the movable groove is provided with tooth grooves.
