[0002] Groundwater sampling refers to the collection of water samples from underground aquifers for purposes such as water quality analysis, groundwater environment monitoring, and hydrogeological research. Through sampling and analysis, we can understand the chemical composition, physical properties, and microbial characteristics of groundwater, providing a scientific basis for the development, utilization, and protection of groundwater resources.
[0003] Most existing stratified sampling devices for groundwater testing directly store groundwater samples inside a storage device. If the temperature inside the storage device fluctuates, it may cause the groundwater to deteriorate or undergo chemical reactions.
[0004] To address this issue, the present invention provides a stratified sampling device for groundwater testing, in order to solve the aforementioned problems. Utility Model Content

[0012] Beneficial effects
[0013] This invention provides a stratified sampling device for groundwater detection and testing. Compared with the prior art, it has the following advantages:
[0014] (1) In this stratified sampling device for groundwater testing, the operator moves the gantry to the groundwater location to be sampled, starts the motor, and the motor drives the winding roller to rotate. When the winding roller rotates, it drives the preservative storage tank to press down into the groundwater for sampling through the connecting line. The location of the storage tank can be monitored in real time through the positioning device. When the preservative storage tank drives the storage tank to press down to the groundwater location to be sampled, the first annular slide rail is activated. The first annular slide rail drives the test tube to rotate to the bottom of the water delivery pipe through the rotating block and suction cup. The suction cup can be used to adsorb and fix the test tube to prevent the liquid inside the test tube from shaking when the storage tank moves. The system sprays water, starts the water pump, and draws groundwater through the pumping chamber and injects it into the test tube through the water delivery pipe to complete the sampling. At the same time, the cooperation of the first annular slide rail, multiple rotating blocks, and multiple test tubes allows groundwater samples to be taken from different depths and stored separately. When the test tube is injected with the sampling water, the first annular slide rail moves the test tube to the bottom of the delivery pipe through the rotating blocks, opens the solenoid valve, and the preservative in the preservative storage tank drips into the test tube through the delivery pipe under the influence of gravity, extending the storage time of the sampled water as much as possible. The temperature control plate is activated, and the temperature control plate maintains the temperature inside the storage chamber at four degrees, further extending the storage time of the sampled water.
[0015] (2) When the preservative is injected into the test tube, the first annular slide rail drives the test tube to rotate to the bottom of the extrusion plate through the rotating block. The bottle stopper inside the bottle stopper storage box falls into the extrusion plate under the influence of gravity. The extrusion plate clamps the bottle stopper and extends to the bottom of the extrusion plate. The extrusion plate is activated and extends to insert the bottle stopper into the test tube for sealing, so as to avoid the water sampled inside the test tube from spilling.
