[0028] See attached Figure 1-4 As shown, an embodiment of the utility model is a groundwater detection pretreatment device, including a sampling tube 103, a plurality of sampling ports 300 are opened on the surface of the sampling tube 103, a lifting assembly for lifting the sampling tube 103 upward is arranged on the top of the sampling tube 103, a guide tube 102 is fixedly arranged on the bottom of the sampling tube 103, the inner cavity of the sampling tube 103 is connected with the inner cavity of the guide tube 102, a filter paper 501 is arranged between the sampling tube 103 and the guide tube 102, and a conical block 100 is threadedly connected to the water outlet end of the guide tube 102.

[0029] The filter plate 301 installed in the sampling port 300 blocks large particles of impurities in the water. When the sampling tube 103 is filled with groundwater, the device is pulled upward and the conical block 100 is removed to pour the groundwater in the sampling tube 103 into the container. While pouring, the filter paper 501 filters the groundwater, thereby filtering out fine impurities in the groundwater, thereby ensuring the accuracy of groundwater detection.

[0030] The lifting assembly includes a pull ring 201 fixedly installed on the top of the sampling tube 103, and a first cable 202 is connected to the surface of the pull ring 201. Through the setting of the first cable 202, it is convenient for the user to grab the first cable 202 and slowly lower the first cable 202 to the position to be detected, so that the device enters the water body.

[0031] A sealing ring 104 is slidably connected to the surface of the sampling tube 103, and fixed blocks 200 are fixedly installed on both sides of the sealing ring 104. The tops of the two groups of fixed blocks 200 are fixedly connected with second cables 206. A limiting ring 205 is fixedly sleeved on the outer surface of the sampling tube 103 near the top, and two groups of support rods 204 inclined toward the center of the sampling tube 103 are fixedly installed on the top of the limiting ring 205. A guide ring 203 is fixedly installed on the top of the two groups of support rods 204. One end of the two groups of second cables 206 extends upward from the inner cavity of the guide ring 203. The two groups of second cables 206 are limited by the setting of the guide ring 203, so that the two groups of second cables 206 can be pulled upward smoothly.

[0032] The inner cavity of the sampling port 300 is fixedly provided with a filter plate 301 . The filter plate 301 installed in the sampling port 300 blocks large impurities in the water and prevents the sampling port 300 from being blocked by the larger impurities.

[0033] The surface of the water outlet end of the sampling tube 103 is provided with an external thread 400, and the inner cavity of one end of the guide tube 102 is provided with an internal thread 401 corresponding to the external thread 400. One end of the guide tube 102 is threadedly connected to one end of the sampling tube 103. The setting of the external thread 400 and the internal thread 401 facilitates the disassembly of the guide tube 102 and the replacement of the filter paper 501.

[0034] A threaded column 402 is provided on the top of the conical block 100, and a waterproof gasket 101 is sleeved on the surface of the threaded column 402. The threaded column 402 is threadedly connected to the inner cavity of one end of the guide tube 102. The two ends of the waterproof gasket 101 are respectively tightly attached to the surface of the guide tube 102 and the conical block 100, thereby blocking the gap between the conical block 100 and the guide tube 102, thereby preventing water from flowing out of the gap between the conical block 100 and the guide tube 102.

[0035] Rubber rings 500 are respectively arranged on the upper and lower sides of the filter paper 501. The top of the rubber ring 500 located at the upper side is in close contact with the surface of the sampling tube 103, and the bottom of the rubber ring 500 located at the lower side is in close contact with the top of the inner cavity of the guide tube 102. The filter paper 501 is pressed and fixed to ensure that the filter paper 501 is in a tensioned state, thereby achieving a good filtering effect.

[0036] When using the embodiment of the utility model, the first cable 202 is lowered to the position to be detected, so that the device enters the water body, and the groundwater flows into the sampling tube 103 through the sampling port 300. The filter plate 301 installed in the sampling port 300 blocks large impurities in the water. When the sampling tube 103 is filled with groundwater, the two sets of second cables 206 are pulled upward to pull the device out of the water body, and the sealing ring 104 slides upward so that the top of the sealing ring 104 abuts against the surface of the limit ring 205, and the sampling port 300 is sealed. Closed to prevent the water in the sampling tube 103 from spilling out while moving upward. When taking it out, remove the conical block 100 to pour the groundwater in the sampling tube 103 into the container. While pouring, the filter paper 501 filters the groundwater. When the filter paper 501 needs to be replaced, threadedly remove the guide tube 102, remove the rubber ring 500 close to the guide tube 102, and then take out the filter paper 501 and replace it. Then put back the rubber ring 500, and thread the guide tube 102 and the sampling tube 103 together.
