Description

Technical Field

[0001] The utility model belongs to the technical field of hydrological monitoring, and more specifically, particularly relates to a water quality monitoring sampling device. Background Art

[0002] When conducting hydrogeological surveys, it is often necessary to sample and test water sources such as rivers and lakes. When sampling existing water sources, testers usually put a sampling bottle into the water. After the sampling is completed, the sample water is tested to analyze the chemical composition of the water source.

[0003] The existing application number is: CN201821209195.0 The utility model relates to a water quality monitoring sampling device, which belongs to the field of environmental monitoring technology. The counterweight is installed at the bottom of the bracket, the bracket is a rectangular frame, and the screw mouth of the screw sampling bag faces upward; a pair of pull rings are provided at the top of the bracket for connecting the cable, a pair of upper clamps are also installed at the top of the bracket frame, a lower clamp is provided at the bottom of the bracket frame, a screw clamp is provided at the middle position of the upper frame of the bracket, and the screw clamp is composed of two half rings, and a small bracket is also provided at the top of the bracket. A through hole is provided in the center of the small bracket, and a pull rod is vertically movably installed in the through hole. The lower end of the pull rod is connected to a lid, and the lid covers the screw mouth of the screw sampling bag; the top of the pull rod is connected to the pull rope through a ring buckle. The water quality monitoring sampling device provided by the utility model installs the screw mouth sampling bag in the bracket and directly puts it into the water for sampling. During the process of retracting and releasing the sampling device, the screw mouth of the screw mouth sampling bag is covered with the lid.
