Online monitoring device for groundwater quality

Abstract

The invention discloses an online monitoring device for groundwater quality. The online monitoring device comprises a buoyancy device, wherein the buoyancy device comprises a hollow through structure;a sensor is arranged in the through structure; the bottom of the buoyancy device downward extends to form a hollow-out body. The online monitoring device for the groundwater quality has low equipmentexpenses and high working efficiency, and can perform long-term dynamic monitoring for groundwater.

Description

technical field [0001] The invention belongs to groundwater monitoring technology, in particular to a groundwater quality on-line monitoring device and a groundwater quality on-line monitoring system. Background technique [0002] With the rapid development of industrial production, the problem of groundwater pollution in my country has become increasingly prominent, and the impact of groundwater pollution on the environment and economic development has also become increasingly apparent. [0003] At present, developed countries have invested a lot of manpower and material resources to restore the polluted areas. Groundwater quality monitoring is an indispensable key technology. In order to ensure the safety of the ecological environment system and the sustainable use of groundwater, groundwater must be effectively monitored. Sampling barrels and inertial pumps are mostly used in China to collect groundwater samples, but this method has high equipment costs and may cause seco...

AI Technical Summary

Problems solved by technology

In China, sampling barrels and inertial pumps are mostly used to collect groundwater samples, but this method has high equipment costs and may cause secondary pollution to the liquid to be tested, making it impossible to perform long-term dynamic monitoring of groundwater quality.

[0004] And for underground water quality monitoring, Chinese patent a kind of underground water quality monitoring system downhole data acquisition device (authorized announcement number CN205175953U) discloses a kind of device that carries out data acquisition to underground water quality in underground, and its groundwater quality monitoring sensor is installed on the fixed plate On the top, and the fixed plate and the protective cover are fixed to each other to make the groundwater quality monitoring sensor go deep into the protective cover, and there is a floating ball above the protective cover, and a mounting plate for installing a junction box is further arranged above the floating ball. The entire data The acquisition device is finally hoisted down the well by steel ropes, etc., and the protective cover equipped with groundwater quality monitoring se
