AI Technical Summary

Technical Problem

Existing soil and groundwater sampling devices are prone to clogging of the water collection point with mud during drilling, which makes it impossible to effectively collect groundwater and affects the accuracy of monitoring data.

Method used

The system employs a lifting mechanism in conjunction with a soil sampling assembly. Soil samples are obtained by rotating an auger. A sleeve and locking structure are installed on the surface of the drill bit body to prevent soil from entering the sampling chamber. An electromagnet is used to control the rotation of the sleeve to open and close the water inlet hole, ensuring that groundwater can smoothly enter the sampling chamber.

Benefits of technology

This improved the accuracy of soil and groundwater monitoring data, prevented soil from clogging the inlet holes, and ensured the smooth collection of groundwater and the accuracy of monitoring data.

Abstract

The invention discloses a sampling device for soil groundwater pollution monitoring, and relates to the field of water sampling, the sampling device comprises a top plate fixedly mounted at the top of a bottom plate through two side plates, and also comprises a mounting plate arranged between the two side plates through a lifting mechanism and capable of longitudinally sliding, the lifting mechanism comprises a driving wheel and a driven wheel which are fixedly mounted at the tops of the two lead screws respectively and are driven through a belt, soil sampling assemblies are arranged at the top and the bottom of the mounting plate, each soil sampling assembly comprises an auger movably mounted at the top of an inner cavity of the sampling barrel, and a water taking assembly is fixedly arranged at the bottom of each auger. According to the equipment, the second water inlet hole is blocked by the sleeve, a large amount of soil is prevented from entering the sampling cavity during drilling and interfering with water quality monitoring data, the accuracy of monitoring numerical control is improved, meanwhile, the clamping block is clamped in the first water inlet hole, it is avoided that the soil is blocked in the first water inlet hole during drilling, and it is avoided that the first water inlet hole is blocked when underground water is collected; and underground water cannot enter the sampling cavity.
