Underground water quality monitoring and sampling device and use method thereof

Abstract

The invention discloses an underground water quality monitoring and sampling device and a use method thereof. The device comprises an operation round disc and a positioning circular ring, wherein thebottom of the operation round disc is connected with the positioning circular ring through a connecting rod, three hanging rings are arranged on a lifting round disc at the bottom of the operation round disc and are fixedly connected with one end of a steel wire rope, the other end of the steel wire rope bypasses a lifting pulley and a transition pulley and is fixedly connected with an automatic paying-off coiling block, and the bottom of the lifting round disc is connected with a sampling cylinder body through a support rod; an inner cavity of the sampling cylinder body is divided into multiple sampling inner cavities by a plurality of separation layers fixedly arranged in the sampling cylinder body, water inlets are annularly formed in the tops, below the sampling inner cavities, of theseparation layers, and a filtering net is arranged on the water inlets; and a sampling pipe is arranged in each sampling inner cavity. According to the underground water quality monitoring and sampling device, underground well water at different depths can be collected and sampled once, so that the sampling diversity is realized, and the time and the labor are saved.

Description

technical field [0001] The invention belongs to the technical field of groundwater quality sampling, and in particular relates to a groundwater quality testing and sampling device, and also relates to a method for using the groundwater quality testing and sampling device. Background technique [0002] In order to make rational use of groundwater resources for a long time, groundwater sampling technology plays an important role in groundwater pollution and prevention, groundwater environmental monitoring, and research on groundwater hydrogeochemical characteristics. The accuracy and accuracy of groundwater test results largely depend on the obtained Quality of groundwater samples. Therefore, whether the in-situ groundwater samples of the target section can be collected is the key to the success of groundwater monitoring and control and the correctness of groundwater cycle analysis. In order to successfully obtain representative groundwater samples, developed countries have co...

Problems solved by technology

[0003] Among them, sampling equipment such as conventional samplers, sampling pumps, and fixed-depth samplers are often used for well water sampling. Although these sampling equipment have the characteristics of lightness, flexibility, and high sampling quality, they cannot meet the one-time stratification of underground well water. Sampling, collecting and sampling underground well water at different depths, making sampling troublesome, inconvenient to operate, and time-consuming and labor-intensive
