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] The existing sampling devices for monitoring groundwater generally can only sample a specific water level each time. If the groundwater is sampled in layers, it needs to be repeatedly operated, which is inefficient. The steel wire rope of the sampling device needs to be rewound, but in the process of rewinding, the surface of the steel wire rope is easy to absorb impurities in groundwater, and at the same time, water stains will also adhere to the surface of the steel wire rope. When the water stains remain on the steel wire rope for a long time , it is easy to cause the surface of the wire rope to rust

Embodiment 1

[0032] Example 1, refer to Figure 1-7 , a layered sampling system for groundwater monitoring, including a fixing frame 1, in order to realize the winding of the wire rope 19 through the rotation of the output shaft of the servo motor 16, the outer wall of the top of the fixing frame 1 is fixedly connected with the servo motor 16 by bolts, and The output shaft of the servo motor 16 is connected with a main shaft 17 through a coupling, the outer wall of the main shaft 17 is fixedly connected with a winding roller 18, and the inner wall of the winding roller 18 is wound with a wire rope 19;

[0033] In order to fix the fixing frame 22 on the bottom of the wire rope 19, a hook 20 is connected to the outer wall of one end of the wire rope 19, and the outer wall of the hook 20 is hung with a hanging ring 21, and the outer wall of the bottom of the hanging ring 21 is welded with a fixing frame 22;

[0034] In order to describe the specific installation positions of the collecting cy...

Embodiment 2

[0037] Example 2, refer to Figure 1-2 , this embodiment is optimized on the basis of Embodiment 1, specifically:

[0038]The inner wall of the top of the fixing frame 1 is welded with a back plate 2, and the outer wall of one side of the back plate 2 is provided with a positioning mechanism 3. The positioning mechanism 3 includes a positioning wheel 31, a first gear 32, a second gear 33, a scale line 34, and an indicator arrow 35. The first gear 32 is fixedly connected to one side of the outer wall of one of the positioning wheels 31, the second gear 33 is engaged with the outer wall of the first gear 32, the scale line 34 is glued to the outer wall of the second gear 33, and the indicating arrow 35 is welded. On the bottom of one side outer wall of the back plate 2, since the wire rope 19 is located between the two positioning wheels 31, when the wire rope 19 moves downward, it will drive the two positioning wheels 31 to rotate, and one of the positioning wheels 31 will driv...

Embodiment 3

[0039] Example 3, refer to Figure 1-3 , this embodiment is optimized on the basis of Embodiment 1, specifically:

[0040] The bottom outer wall of the back plate 2 is provided with a cleaning mechanism 4, and the cleaning mechanism 4 includes a support rod 41, a mounting ring 42, and a snap ring 43. The symmetrically distributed mounting rings 42 are welded to the outer wall of one side of the support rod 41, and the snap ring 43 is bonded On the inner wall of the mounting ring 42, when the fixing frame 22 moves upward, the wire rope 19 will be continuously reeled onto the winding roller 18, and the wire rope 19 will pass through the snap ring 43 at this time. Contact, not only can clean up the stolen goods attached to the surface of the wire rope 19 to ensure the cleanliness of the wire rope 19, but also can clean up the water stains on the surface of the wire rope 19 to avoid the problem of rusting caused by excessive moisture on the surface of the wire rope 19.

Abstract

The invention belongs to the technical field of underground water monitoring, particularly relates to a layered sampling system for underground water monitoring, and aims to solve the problems that layered sampling of underground water in the background technology needs repeated operation and impurities and water stains on the surface of a steel wire rope are difficult to clean. A back plate is welded to the inner wall of the top of the fixing frame, and a positioning mechanism is arranged on the outer wall of one side of the back plate. The downward moving height of the fixing frame can be observed all the time, the specific layering position of underground water can be conveniently determined, the sealing performance of the underground water after sampling is also ensured under the mutual cooperation of a rubber sealing ring and a cover plate, dirt and water stains attached to the surface of a steel wire rope can be cleaned away due to the tight contact between a clamping ring and the steel wire rope, and the safety of underground water sampling is improved. Under the mutual cooperation of the sampling needle cylinder, the water outlet pipe and the valve, accurate sampling of underground water at different levels is realized, and convenience is provided for subsequent monitoring equipment to monitor the underground water in the sampling needle cylinder.

Description

technical field [0001] The invention relates to the technical field of groundwater monitoring, in particular to a hierarchical sampling system for groundwater monitoring. Background technique [0002] Groundwater refers to the water that occurs in the rock voids below the ground, and in a narrow sense refers to the water in the saturated aquifer below the groundwater level. In the national standard "Hydrogeological Terminology" (GB / T14157-93), groundwater refers to various forms of gravity water buried below the surface. Foreign scholars believe that there are three definitions of groundwater: First, it refers to all the water buried in groundwater that is significantly different from surface water, especially the part of the water in the saturated zone of the aquifer; saturates, and replenishes springs and wells; the third is water stored in underground rock cavities, in the voids that make up the crustal material. Groundwater is an important part of water resources. Beca...
