Description

Technical Field

[0001] The utility model relates to the technical field of groundwater monitoring, in particular to a groundwater salt-fresh interface change monitoring device based on the densitometer principle. Background Art

[0002] According to the retrieval of Chinese patent publication number: CN215640335U, a groundwater detection device for groundwater evaluation is disclosed, which relates to the field of groundwater detection technology. The utility model includes two side plates arranged in alignment with each other, and a built-in shaft is rotatably installed between the opposite sides of the two side plates, and a wire drum is rotatably installed on one side of the two side plates. When the water collecting tube is placed into the groundwater, the main hanging line first bears the gravity of the water collecting tube and the pressure rod, and the closing component of the pressure rod at one end of the water collecting tube closes the water collecting tube to prevent water sources at other depths from entering the water collecting tube. After the water collecting tube reaches the specified depth, the wire drum is fixed to fix the position of the water collecting tube, and the main hanging line continues to relax, so that the pressure rod releases the closing component from closing the water collecting tube, allowing the water source at this depth to enter the water collecting tube. After the collection is completed, the main hanging line pulls the pressure rod and the water collecting tube again, and after the closing component at one end of the pressure rod closes the water collecting tube again, the water collecting tube can be pulled out, thereby realizing the collection of water sources at different depths.

[0003] However, when implementing the above technical scheme, there are the following problems: the above technical scheme realizes the collection operation of water sources at different depths, but after collecting water sources at different depths, the water source cannot be detected quickly, and the water collection tube needs to be recovered. The process is relatively cumbersome and the detection efficiency is low. For this reason, the utility model provides a groundwater salt-fresh interface change monitoring device based on the principle of a density meter. Utility Model Content

[0005] To achieve the above purpose, the utility model is implemented by the following technical scheme: a groundwater salt-fresh interface change monitoring device based on the densitometer principle includes a workbench, a sampling mechanism is provided on the top of the workbench for implementing the sampling operation of groundwater, and a detection mechanism is provided inside the workbench for implementing the detection operation of the salt-fresh change of groundwater, and the detection mechanism includes:

[0015] Beneficial Effects

[0016] The utility model provides a groundwater salt-fresh interface change monitoring device based on the densitometer principle. Compared with the prior art, it has the following beneficial effects:

[0017] (1) The groundwater salt-fresh interface change monitoring device based on the density meter principle starts the driving motor to drive the driving rod, driving plate, arc block and rotating rod to rotate synchronously. The arc block slides on the inner surface of the arc groove, and the rotating rod contacts the rotating block when rotating, so that the rotating block, rotating disk, connecting rod and placement plate rotate synchronously by 90 degrees and then stop. At this time, the second sampling tube is located below the sample outlet tube. Then, the height of the sampler is adjusted by controlling the placement motor to achieve sampling of groundwater at different depths. At the same time, the staff takes out the density needle and puts it into the first sampling tube to achieve the detection operation of the saltiness of the groundwater. Driven by the driving motor, the placement plate and the sampling tube are intermittently rotated, so that multiple groups of sampling tubes stop after rotating to the bottom of the sample outlet tube, which can better collect groundwater. At the same time, when the groundwater salinity is detected, it does not affect the subsequent collection of groundwater, thereby improving work efficiency.

[0018] (2) The device for monitoring the change of salt-fresh interface of groundwater based on the principle of density meter starts the sampler motor to drive the sampler rod, rope roller and scale plate to start rotating synchronously, so that the sampler, rope and hose slide downward synchronously and immerse in the groundwater to realize sampling operation, and the height of the sampler is recorded by the scale plate, and then the sampling operation of groundwater is realized by starting the water pump, and the groundwater is introduced into the interior of the collection bottle through the sample outlet pipe. Driven by the sampler motor, the height of the sampler is flexibly adjusted, and the height of the sampler is recorded by the scale plate, so as to better perform sampling operation on groundwater at different depths.
