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...

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 sensors is located below the water surface of the well water, and the floating ball floats on the water surface of the well water. The constant change with the seasons and the uncertainty of the movement of the floating ball on the water surface are extremely easy to cause the floating ball to be stuck at a certain position on the well wall when the water level in the well rises and cannot float upward with the change of the water level. As a result, the junction box installed on the installation board was submerged below the surface of the well water for a long time and entered water, which made it impossible to transmit the groundwater quality monitoring data to the outside. When the water level rises greatly, the steel rope will often bend in a serpentine shape or even twist. In addition to its inherent gravity, the steel rope will often be pressed on the junction box and the floating ball, causing the floating ball to fail to float normally. As a result, the junction box has been submerged below the surface of the well water for a long time, resulting in the inability to transmit groundwater quality monitoring data to the outside.
