Sampling device for river water quality detection

Abstract

The invention provides a sampling device for river water quality detection, and belongs to the technical field of environmental protection equipment, and the sampling device comprises a support bottomplate, a support vertical rod rotatably arranged at the upper part of the support bottom plate, a protection box body telescopically connected to the side wall of one end, far away from the support bottom plate, of the support vertical rod, and a sampling assembly arranged at the bottom of the protection box body; and the sampling assembly comprises a sampling cylinder, and a through hole is formed in the side wall of the sampling cylinder. According to the embodiment of the invention, after the support bottom plate is fixed, by rotating the support vertical rod, the protection box body drives the sampling assembly to move to the position above a river channel, and the sampling assembly stretches into river water; the driving assembly drives a round rod and a square rod to be away from asampling barrel through a transmission assembly, and a plug body is driven to be separated from the through hole, so that the river water can enter the sampling barrel from the through hole, and riverwater sampling is achieved. The device has the advantages of convenience in use and good sampling effect, and the accuracy and reliability of subsequent detection results are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, in particular to a sampling device for river water quality detection. Background technique [0002] The quality of river water has a crucial impact on the ecological environment of the river. At present, most of the detection of river ecology is to judge whether the river ecology is healthy by sampling the river water and analyzing its components. [0003] In the prior art, most of the sampling of river water is to directly put the sampling cylinder into the river water, and then pull the sampling cylinder back after scooping up the river water. Although this sampling method is relatively simple, it can only sample the river water on the surface of the river. , it is impossible to sample the flowing water in the depth of the river, which leads to insufficient accuracy and reliability of the subsequent detection results.
