Problems solved by technology

The existing groundwater samplers in China are often complex in structure, large in size, and cumbersome to operate. When collecting groundwater samples, they will be in contact with the air to distort the data, and the application range is relatively limited, so one device cannot be used for multiple purposes.

Embodiment Construction

[0015] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as Figure 1-3 As shown, a multi-layer groundwater sampling system for a well based on electromagnet docking includes an inner pipe 1, an outer pipe 2 and a sampler. There are flower holes 5, and the inner pipe 1 is arranged in the inner center of the outer pipe to align with the center of the outer pipe. In the gap between the outer pipe and the inner pipe, there are several groups of water-repellent layers 6 at intervals relative to the position of the underground aquifer. Layer 6 includes two layers of water-proof materials respectively located at the top and bottom of the relative underground aquifer, and the position of the inner pipe 1 corresponding to the underground aquifer is provided with an outwardly convex conical water outlet interface 7; the sampler includes a sampling pipe 3...

Abstract

The invention provides a butt-joint one-well multilayer groundwater sampling system based on an electromagnet. The system comprises an inner tube, an outer tube and a sampler, wherein the outside of the outer tube is jointed with the well wall, a flower hole is formed in a position, corresponding to a underground aquifer, on the outer tube, the inner tube is arranged at the center in the outer tube and is aligned to the center of the outer tube, a discharged water interface is formed in a position, corresponding to the underground aquifer, on the inner tube, multiple groups of water isolation layers are arranged at positions opposite to the underground aquifer in a gap between the outer tube and the inner tube at intervals, the sampler comprises a sampling tube and a sampling joint, a sampling interface is formed in the lower side face of the sampling tube, the top of the sampling tube is connected with a sucking pump, and the sampling interface is configured with the discharged water interface. The butt-joint one-well multilayer groundwater sampling system provided by the invention is used for guaranteeing the validity of a water sample to the maximum degree, and is long in service life and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of groundwater sampling, in particular to an electromagnet-based one-well multi-layer groundwater sampling system. Background technique [0002] With the increasing water pollution, there are more and more monitoring of groundwater pollution at home and abroad. To monitor groundwater, the first thing to do is to collect groundwater samples. At present, depth-fixed samplers are mainly used for deep-layer groundwater sampling, or the method of pumping water directly into the observation hole. The water samples obtained are mostly surface water samples or mixed water samples. samples, and can only collect water samples from a single groundwater layer. For such a complex underground environment, it has strong stratification, and the layers are often separated by solid materials such as soil and rock, so it is difficult to take stratified sampling. The existing groundwater samplers in China are often complex in...
