Abstract

The invention discloses a one-time layering sampling a plurality of unmixed groundwater samples device and a method. The one-time layering sampling the plurality of unmixed groundwater samples device comprises a cable, a counterweight, a control module and a water sampling device. The water sampling device comprises a stepping motor, an inner layer sleeve and an outer layer sleeve. The control module is connected with the stepping motor through the cable. The outer layer sleeve is fixedly connected with a stator of the stepping motor. The inner layer sleeve is fixedly connected with a rotor of the stepping motor. The outer layer sleeve is arranged outside the inner layer sleeve in a sleeved mode. The inner layer sleeve can rotate relative to the outer layer sleeve under the effect of the rotor of the stepping motor. The counterweight is fixed on the bottom portion of the outer layer sleeve. The one-time layering sampling the plurality of unmixed groundwater samples device is simple in structure, novel in style and strong in sealing performance. The one-time layering sampling the plurality of unmixed groundwater samples device can sample a plurality of water samples in a layering mode in one time, and the sampled water samples are unmixed water samples.

Description

technical field [0001] The invention relates to a device and method for collecting groundwater samples, in particular to a device and method for collecting multiple unmixed groundwater samples in layers at one time. Background technique [0002] In recent years, a large number of reservoir dams have been built in my country, but most of the reservoirs have leakage problems; the ocean has a great impact on coastal cities, and more and more researches on the marine environment; with the development of industry, lakes The study of water quality is related to the sustainable development of our country, and these problems all involve the study of water samples, so the collection devices and methods of water samples are particularly important. The water collection device in the prior art is relatively simple, and when collecting water samples, only one water sample of a certain water layer can be taken at a time, and most of the water samples collected are mixed water samples, whic...
