Organic matter sampling device in underground water

Abstract

The invention discloses an organic matter sampling device in underground water. The organic matter sampling device comprises a sampling tank, a water inlet, a collection box, an absorption device anda drain pipe, wherein the collection box is arranged at the top of the sampling tank, a movable plate is arranged in the sampling tank, a guide pipe is arranged on an upper surface of the movable plate, a sleeve is fixedly connected to the upper surface of the movable plate, a screw rod is arranged in the sleeve, a motor is fixedly connected to a right side wall of the sampling tank, a driving shaft is fixedly connected to a shaft extension end of the motor, a first bevel gear and a second bevel gear sleeve an upper end of the screw rod, a half-conical gear sleeves a left end of the driving shaft, and a lower end of a telescopic hose extends to the underground water. The moving plate is driven to move upwards and downwards by the motor, and the underground water is constantly pumped into the sampling tank; and meanwhile, large particle impurity in the underground water is filtered by a sieving plate, organic matter constituent in the underground water is absorbed by the absorption device, the underground water is stirred by stirring blades, the releasing of the organic matter constituent in the underground water is facilitated, and the sampling efficiency is improved.

Description

technical field [0001] The invention relates to an environmental monitoring device, in particular to a sampling device for organic matter in groundwater. Background technique [0002] Groundwater refers to the water that exists in the rock voids below the ground. In a narrow sense, it refers to the water in the saturated aquifer below the groundwater surface. Foreign scholars believe that there are three definitions of groundwater: one refers to all the water buried in groundwater that is significantly different from surface water, especially the water in the saturated zone of the aquifer; the other is downward flow or infiltration, which makes soil and rock The water that saturates and replenishes springs and wells; the third is the water stored in underground rock cavities and in the interstices of the material that makes up the earth's crust. Groundwater is an important part of water resources. Due to the stable water quantity and good water quality, it is one of the imp...

Problems solved by technology

However, under certain conditions, changes in groundwater can also cause unfavorable natural phenomena such as swamps, salinization, landslides, and land subsidence.

[0003] With the increasingly serious environmental pollution, there are more and more organic components in groundwater in many areas. The existing organic sampling devices in groundwater are difficult to achieve continuous sampling, and the sampling efficiency is low.
