Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixed-point water sampling technology, and in particular to a fixed-point water sampling device for groundwater environment survey. Background Technology
[0002] The groundwater environmental survey fixed-point sampling device is an intelligent system developed and designed based on a basic groundwater sampling flowchart. The sampling pump is one component, comprising an airbag pump and a groundwater sampling pump. The airbag pump enables undisturbed and cross-contamination-free precise sampling, suitable for scenarios requiring high sampling accuracy. The groundwater sampling pump, with its flow regulation function, can be used for both well washing and sampling, suitable for scenarios with heavy workloads and tight deadlines.
[0003] Current groundwater environmental survey sampling devices do indeed face complex environmental challenges in practical use. Especially when the silt contains a significant amount of debris, this debris can clog the sampling device, affecting sampling efficiency. This debris may include particulate matter, fibers, or other impurities, which can adhere to critical parts of the sampling device, such as filters and pipes, causing poor water flow or complete blockage.
[0004] Debris can also damage the water sampling device and shorten its service life. Some sharp or hard debris may scratch or abrade the material of the water sampling device, causing its performance to deteriorate or malfunction.
[0005] When there is a lot of debris in the silt, the accuracy of water sampling will also be affected. Debris may interfere with the measurement of water quality parameters, leading to biased results. For example, water quality parameters such as color, turbidity, and colloid content can be affected by debris, thus affecting the readings of water quality analyzers. Utility Model Content

[0009] The upper end of the drill pipe is equipped with an assembly head, through which an assembled water sampling pipe is connected, thereby increasing the length of the drill pipe and increasing the drilling depth into the ground. The side wall of the assembled water sampling pipe is equipped with a handle, which makes it convenient for users to operate the assembled water sampling pipe and the drill pipe for water sampling.
[0010] The assembled water sampling pipe is connected to a connecting pipe via a connector and a connecting sleeve. A docking seat is installed at the upper end of the connecting pipe. A filter seat is installed at the upper end of the docking seat via fasteners. A secondary pipe connector is provided on the side wall of the filter seat. The secondary pipe connector is connected to a squeezing ball via a connecting hose. The filter seat has filter mesh openings. A sampling bottle is installed on the filter seat, and the squeezing ball is pressed to draw water into the sampling bottle to achieve the water sampling operation.
[0011] The lower end of the drill pipe is shovel-shaped and the drill pipe and the assembly head are designed as one piece. The side wall of the assembly head is provided with a screw hole. The assembled water intake pipe is threaded to the assembly head and bolts are inserted to achieve a tight connection between the assembled water intake pipe and the assembly head. A sealing ring is provided at the connection between the assembled water intake pipe and the assembly head.
[0012] The connector is integrated with the assembled water intake pipe. The connector is threaded to the connecting sleeve, the connecting sleeve is threaded to the connecting pipe, and the connecting pipe is inserted into the assembled water intake pipe. A sealing ring is provided at the connection between the connecting pipe and the assembled water intake pipe.
[0013] The connecting pipe and the docking seat are connected by threads, and a sealing ring is provided at the connection between the connecting pipe and the docking seat. The docking seat has a screw hole in the middle, and a filter seat is mounted on the docking seat. The filter seat has a screw hole in the middle, and a bolt is inserted into the screw hole to fix the filter seat on the docking seat.
[0014] The auxiliary pipe connector and the docking seat are designed as an integral part, and the auxiliary pipe connector is equipped with a filter sponge inside. The connecting hose and the auxiliary pipe connector are connected by threads, and a sealing ring is provided at the connection between the auxiliary pipe connector and the connecting hose.
[0015] The extrusion ball and the connecting hose are designed as a single unit. The cross-section of the extrusion ball is elliptical, and the connecting hose is a telescopic tube.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The modular design combining the sampling pipe and drill pipe allows for easy increases in drill pipe length and drilling depth, thus meeting the needs for groundwater sampling at different depths. This design not only improves sampling efficiency but also makes the device more flexible and practical. The filtration mechanism effectively removes larger impurities and particles from the water, ensuring the quality of the collected water samples.
[0018] The elliptical cross-section design of the squeeze ball makes it easier for users to operate; water can be easily drawn into the sampling bottle simply by pressing the squeeze ball. This design not only simplifies the water collection process but also improves the user experience.
[0019] The device is equipped with sealing rings at all connections to ensure a tight seal and prevent leakage. This not only guarantees the smooth progress of the water collection process but also ensures the accuracy and reliability of the collected water samples. Attached Figure Description
