Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a groundwater sampler. Background Art

[0002] Groundwater is a vital component of water resources. Due to its stable flow and high quality, it is widely used as a key water source for agricultural irrigation, industrial and mining industries, and urban areas. To promote environmental protection and sustainable development, groundwater testing is often necessary. Groundwater sampling helps improve the accuracy and temporal resolution of environmental monitoring, providing timely insights into the quality and contamination of groundwater resources.

[0003] Groundwater sampling is usually carried out in deep wells, groundwater wells, or other groundwater sources. These water sources have complex environments and may contain a large amount of impurities such as silt. During the groundwater sampling process, silt from the groundwater mixes into the sampler, which may affect the physical, chemical, and biological properties of the water sample, thereby affecting the results of water quality analysis. In addition, silt and other impurities may clog the sampling equipment or analytical instruments, affecting the normal operation and service life of the equipment. Therefore, we propose a groundwater sampler to solve the above-mentioned problems. Utility Model Content

The water storage pipe 6 is threadedly connected to the water pump pipe 3. In this embodiment, the pump 501 drives the turbine 502 to rotate, thereby sucking groundwater from the outside of the filter pipe 1. The groundwater passes through the filter component 2, the water pump component 5, and the conical rubber valve 7 in sequence, and then enters the water storage pipe 6.

[0026] The air outlet component 8 includes an air outlet pipe 801, an air outlet 802 is provided at the bottom of the air outlet pipe 801, a spring 803 is provided at the end of the air outlet pipe 801 away from the water storage pipe 6, the air outlet pipe 801 is fixedly connected to the water storage pipe 6, and a pneumatic pin 804 is provided at the end of the spring 803 near the air outlet 802.

[0029] Working principle: Put the groundwater sampler into the groundwater source, the pump 501 drives the turbine 502 to rotate, and then sucks in groundwater. The groundwater passes through the filter plate 102 to prevent larger foreign matter from entering the filter tube 1 and damaging the filter component 2. The groundwater then passes through the mud guide slope 203 on the top of the filter port 202, and the mud and sand and other impurities in the groundwater are filtered and concentrated in the sliding filter box 204. Then it passes through the water pump component 5, passes through multiple conical rubber sheets 702, and enters the water storage pipe 6. At this time, a large amount of groundwater enters the water storage pipe 6, causing the air pressure to increase. The air pressure passes through the air guide slope 805, pushing the pneumatic pin 804, causing the spring 803 to compress, and then the pressure is released through the air outlet 802. After the groundwater sampling is completed, open the rotating card plate 402, pull out the sliding filter box 204, clean the internal mud and sand impurities, and then rotate the water storage pipe 6 to pour out the collected groundwater.
