Underground water quality periodic change intelligent analysis system and water quality measurement device

Abstract

The invention relates to the technical field of water quality measuring devices, in particular to an underground water quality periodic change intelligent analysis system and a water quality measuring device.The underground water quality periodic change intelligent analysis system comprises a supporting frame, the supporting frame comprises two symmetrically-distributed positioning rods, and an insertion block is fixedly connected between the bottom faces of the two positioning rods; a square shaft is fixedly connected to the middle of the top surface of the inserting block, a positioning pipe is slidably connected to the outer side wall of the square shaft in a sleeving mode, a tray is rotatably connected to the bottom of the positioning pipe, and a plurality of water taking modules are fixedly connected to the outer side of the tray in an annular shape at equal angles. According to the device, a transmission shaft moves downwards to push a downward pressing rod to enable a water taking barrel to move downwards, a sliding rod drives a piston shaft and a piston to move in the water taking barrel, underground water is sucked into the water taking barrel, the downward pressing rod continues to push a square sleeve, the square sleeve is separated from a guide block, and the water taking barrel drives sample water to automatically move upwards to the water surface under the buoyancy action of a floating ball; manual repeated pulling and inserting of a water taking tool for water taking are omitted, and the water taking efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of water quality measurement devices, in particular to an intelligent analysis system for periodic changes in groundwater water quality and a water quality measurement device. Background technique [0002] When studying the periodic changes of groundwater quality, it is often necessary to use water intake tools to extract sample water from the pre-opened water intake holes for water quality testing. During the water intake process, the water intake tools need to be placed in the underground water intake holes, and then the tools containing groundwater Moved to the ground, in order to improve the accuracy of the research results, it is necessary to repeatedly take out multiple samples of water from different depths in the ground. Therefore, researchers need to pick and place water tools in the water intake holes frequently and many times. The entire water intake process is complicated, time-consuming and labor...

[0002] When studying the periodic changes in groundwater quality, it is often necessary to use water intake tools to extract sample water from pre-opened water intake holes for water quality testing. During the water intake process, it is necessary to put the water intake tools into the underground water intake holes, and then put the tools containing groundwater Moving to the ground, in order to improve the accuracy of the research results, it is necessary to repeatedly take out multiple samples of water from different depths underground. Therefore, the researchers need to frequently take and place the water-taking tools in the water-taking holes. The entire water-taking process is complicated, time-consuming, and laborious. As the depth of water intake continues to deepen, it is difficult to quickly remove the water intake tool from the ground, which further affects the efficiency of groundwater quality measurement
