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] In the process of pollution control of groundwater, it is necessary to collect samples of groundwater, that is, water body sampling, but the existing sampling devices cannot perform more accurate sampling of groundwater at a special depth. Therefore, a groundwater Sampling device for detection to solve the above technical problems

Embodiment 1

[0023] see Figure 1-4 , a sampling device for groundwater detection, comprising a support leg 1, a support frame 2 is fixed on the support leg 1, a hand wheel 8 is mounted on the support frame 2, and a hand wheel 8 is mounted on the support frame 2, and a transmission connection is arranged on the support frame 2 The coiling mechanism inside is provided with a steel wire rope 16, and the coiling mechanism is connected with a marking mechanism for marking the length of the steel wire rope 16. The bottom of the steel wire rope 16 is fixed with a connecting stud 27, A settling tube 15 is threadedly installed on the connecting stud 27, and a sampling mechanism is fixed inside the settling tube 15, and an anti-bottoming mechanism is fixed vertically on the bottom of the settling tube 15.

[0024] The coiling mechanism provided in the device lays down the wire rope 16, adjusts the sinking depth of the settling cylinder 15 into the groundwater through the wire rope 16, and then real...

Embodiment 2

[0030] On the basis of Embodiment 1, in addition, the sampling mechanism of this device comprises the sampling conical cylinder 29 that is fixed on the settling cylinder 15, and the bottom of the sampling conical cylinder 29 communicates with and is installed with the vertical pipe 31 that vertically runs through the settling cylinder 15, described In the vertical pipe 31, a piston column 28 is vertically sealed and slidably installed, and the piston column 28 is provided with a flow diversion channel 30 that enables the sampling cone 29 to communicate with the vertical pipe 31. The sampling cone 29 is vertically fixed with a An upright post 26 for the sliding sleeve of the piston rod 28 , and an adjustment spring 25 is fixed between the upright post 26 and the sampling cone 29 . The sampling mechanism also includes a limit plate 17 fixed on the vertical pipe 31, the limit plate 17 is rotatably equipped with an adjustment sleeve 34 threaded on the column 26, and the bottom of t...

Abstract

The invention discloses a sampling device for underground water detection, and relates to the technical field of water body sampling; the sampling device comprises support legs; a support frame is fixed on the support legs; a marking mechanism for marking the placing length of a steel wire rope is in transmission connection with a winding mechanism, and an anti-grounding mechanism is vertically and fixedly mounted at the bottom of a settling barrel; the steel wire rope can be placed through the winding mechanism, so that a sampling mechanism can go deep into an underground water body to perform convenient water body sampling operation; a pointer in the arranged marking mechanism can point to the graduated scale by degrees, and an operator can flexibly and accurately adjust and control the submergence depth of the sampling mechanism, and the sampling accuracy is effectively improved; a piston column in the arranged sampling mechanism can achieve vertical sliding adjustment before sampling, the adjusting effect of the initial pre-tightening force of an adjusting spring is achieved, the piston column can adapt to upward jacking force borne by the piston column at different depths, and the effect of flexibly adjusting water taking at different depths is achieved.

Description

technical field [0001] The invention relates to the technical field of water body sampling, in particular to a sampling device for groundwater detection. 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. In national standards, groundwater refers to various forms of gravity water buried below the 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...
