[0001] The utility model relates to the field of water samplers, and particularly relates to a portable shallow groundwater water sampler. Background Art

[0002] There is a certain amount of groundwater in the environment where we live, and groundwater is an important water resource in China. Therefore, in the work of researching, detecting, analyzing, etc. of groundwater, it is necessary to collect water samples of groundwater. Therefore, the use of a portable shallow groundwater water sampler is very important;

[0003] Chinese Patent Authorization Application No.: CN202221811859.7 provides a portable groundwater sampling device. This solution has a simple structure, low cost and strong practicability, and is suitable for assisting professional technicians to efficiently carry out groundwater sampling operations. With the above structure, the grounding wire is grounded, and the wire is released by rotating the manual crank. When the metal probe touches the water surface, the indicator light flashes and the buzzer sounds, indicating that the bailer is full of water. At this time, read the reading of the water level display, which is the buried depth of the groundwater level. The main function achieved is to measure the water level while washing the well and taking water, which is convenient for recording the water level change; the bailer can descend and ascend at a uniform speed, avoiding disturbing the groundwater environment and ensuring the homogeneity and stability of the sampling; at the same time, the wire is made of copper wire with a rubber outer skin, which is not easy to absorb water, and there is a winch for special storage of the wire, greatly avoiding the risk of cross-contamination between monitoring wells and ensuring the accuracy of groundwater environmental quality monitoring. The utility model provides a portable groundwater well washing and sampling device, which has a simple structure, low cost and strong practicability, is suitable for assisting professional technicians to carry out groundwater well washing and sampling operations, is easy to operate, has various functions, and is beneficial to standard and efficient well washing and sampling during groundwater monitoring.

[0004] There are certain drawbacks in the use of existing water samplers. First, during the sampling process of the water sampler, there may be certain garbage impurities in the groundwater being taken, and these impurity garbage are directly sampled into the water sampler. Over time, the water sampler becomes blocked, affecting the water volume of the water collection and the sampling and detection effect. For this reason, we propose a portable shallow groundwater water sampler. Content of the Utility Model

[0040] By sleeving the filter element 302 on the inner end of the water intake head 301, the groundwater taken in can be effectively filtered. And when the filter element 302 needs to be disassembled, pull a pair of clamping rods 304. The clamping rods 304 adjust their positions under the action of the spring member 308. At this time, the clamping rods 304 are separated from the clamping members 307. The clamping members 307 are adjustable clamping head structures. When the clamping rods 304 are clamped, they can be clamped with the clamping grooves 305, so that the filter element 302 is stably installed inside the water intake head 301.

There are scales on the outside of the adjusting frame 101. When the water sampler 201 at the front end performs downward sampling, the water intake depth can be conveniently observed. Adjusting and pulling the adjusting rod 202 can drive the piston 203 to move, thereby enabling the water sampler 201 to achieve convenient water sampling work.

[0049] During the water intake process, the filter element 302 is sleeved inside the water intake head 301, which can effectively filter the groundwater taken in.
