[0001] This utility model relates to the technical field of groundwater sampling devices, and in particular to a hydrogeological groundwater sampling device. Background Technology

[0002] Groundwater sampling is crucial in fields such as hydrogeological research, environmental monitoring, and water resource management. With increasingly stringent ecological and environmental protection requirements and the growing demand for the rational development and utilization of groundwater resources, higher standards are being set for the accuracy, diversity, and timeliness of groundwater sampling. Traditional sampling devices often only obtain water samples in a single state, making it difficult to meet the needs of complex studies such as groundwater quality changes and pollution stratification.

[0003] To meet the diverse needs of modern hydrogeological work, this groundwater sampling device is designed to achieve intelligent, precise, and efficient sampling. On the one hand, the device is required to have powerful stratified filtration and multi-dimensional simultaneous sampling capabilities, enabling it to acquire water samples at different purification stages and provide abundant data for in-depth analysis of groundwater quality evolution patterns. On the other hand, the device emphasizes automated operation and modular design to ensure rapid installation, convenient use, and easy maintenance in various complex environments.

[0008] As a further embodiment of this utility model: the lower support is threadedly connected to the sampling body, and the electric diaphragm pump is connected to the bottom pipeline of the filter disc.

[0009] As a further improvement of this utility model: the filter disc is a top-opening circular disc structure, a filter layer is fixedly disposed on the inner wall of the filter disc, the filter discs are threadedly connected, and the filtration capacity of the filter layer gradually increases from bottom to top.

[0010] As a further embodiment of this utility model: a rubber tube is fitted onto the surface of the water outlet, the rubber tube engages with the sampling port, a spring shaft is movably fitted onto the inner wall of the rubber tube, and a sealing cover is movably fitted onto the other side of the spring shaft, the spring shaft causing the sealing cover to flip outward.

[0013] Compared with the prior art, this utility model provides a hydrogeological groundwater sampling device, which has the following beneficial effects:

[0014] 1. This utility model features a stepped filter disc that intercepts large particles such as sand and gravel at the bottom and precisely filters out fine suspended matter at the top. With its progressively increasing filtration capacity from bottom to top, the sampling ports are arranged in an orderly fashion, corresponding one-to-one with the filter disc outlets. During the purification process of groundwater through the filter disc, water samples from different stages can flow instantly and accurately into the corresponding sampling bottles. This design breaks through the limitations of traditional single-filtration and single-sampling methods, enabling the acquisition of water samples from different filtration stages within the same sampling process. This provides multi-dimensional and more comprehensive data support for hydrogeological research, greatly enhancing the scientific rigor and research value of the sampling.

[0015] 2. This utility model features an electric diaphragm pump built into the lower support body. After being automatically activated, the pump rapidly extracts groundwater from the inlet and delivers it to the filtration system, replacing the cumbersome and inefficient traditional manual sampling and significantly improving sampling efficiency. The extensive use of threaded connections between components gives the device a high degree of modularity. Connections between the sampling body and the lower support body, the suspension body and the sampling body, and the connecting pipe and the sampling port act like precisely meshed "intelligent interfaces," ensuring stability during installation and facilitating easy maintenance and transportation during disassembly.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

The sampling ports 4 are distributed from bottom to top and engage with the water outlet 7. A support leg 8 is fixedly mounted at the bottom of the lower support body 1, an electric diaphragm pump 9 is fixedly mounted on the inner wall of the lower support body 1, and a water inlet 10 is located at the bottom of the lower support body 1, with the electric diaphragm pump 9 connected to the water inlet 10. Inside the sampling body 2, the filter discs 6 are distributed in a stepped manner, intercepting large particles such as sand and gravel at the bottom and precisely filtering out fine suspended matter at the top. With the filtration capacity gradually increasing from bottom to top, the sampling ports 4 are arranged in an orderly manner from bottom to top, corresponding one-to-one with the water outlet 7 of the filter disc 6. During the purification process of groundwater through filter plate 6, water samples from different levels can flow instantly and accurately into the corresponding sampling bottles 5.

[0025] like Figures 1-4 As shown, the lower support is threadedly connected to the sampling body 2, and the electric diaphragm pump 9 is connected to the bottom pipe of the filter disc 6. The filter disc 6 is a disc structure with an open top. A filter layer is fixedly installed on the inner wall of the filter disc 6. The filter discs 6 are threadedly connected to each other. The filtration capacity of the filter layer gradually increases from bottom to top. A rubber tube 11 is snapped onto the surface of the outlet 7. The rubber tube 11 is snapped onto the sampling port 4. A spring shaft 12 is movably installed on the inner wall of the rubber tube 11. A sealing cover 13 is movably installed on the other side of the spring shaft 12. The spring shaft 12 drives the sealing cover 13 to flip outward.

[0026] like Figures 1-3 As shown, a connecting tube 14 is threaded at the opening of the sampling bottle 5. The connecting tube 14 is threadedly connected to the sampling port 4. A spring shaft 15 is movably installed on the opening side of the connecting tube 14. A sealing cover 16 is movably installed on the other side of the spring shaft 15. The sealing cover 16 is rotated inward by the spring shaft. The sealing cover 16 is parallel to the sealing cover 13. A lifting interface 17 is fixedly installed at the top of the suspension body 3. The suspension body 3 is threadedly connected to the sampling body 2. The lifting interface 17 at the top is compatible with various lifting equipment.

[0027] Working Principle: When using this device, firstly, with the help of the hoisting interface 17 and hoisting equipment, the device is accurately lowered to the target groundwater sampling location. The electric diaphragm pump 9 is started, and under its powerful suction, groundwater flows into the device from the inlet 10 at the bottom of the lower support 1, and then enters the filter plate 6 area of ​​the sampling body 2. Inside the filter plate 6, the groundwater passes through filter layers with increasing filtration capacity from bottom to top, intercepting and filtering large particles, fine suspended matter, etc. Simultaneously, the water samples purified by different filter plates 6 flow through their corresponding outlets 7, along the rubber tube 11, into their corresponding sampling ports 4, and finally into the sampling bottle 5. During the installation of the sampling bottle 5, the connecting tube 14 is threaded tightly into the sampling port 4, and the spring shaft 15 drives the sealing cap 16 to flip inward, tightly fitting it with the sealing cap 13, forming a double-sealed structure that effectively isolates external contamination and ensures the purity of the water sample. After sampling is completed, turn off the electric diaphragm pump 9, remove the device from the sampling point, and disassemble the sampling bottle 5 to obtain a complete sample containing water samples from different filtration stages, which can be used for subsequent professional hydrogeological analysis and testing.
