Description

Technical Field

[0001] The utility model relates to a sampling device, in particular to a groundwater sampling device. Background Art

[0002] Groundwater refers to water stored in the pores of rocks below the ground. In a narrow sense, it refers to water in saturated aquifers below the groundwater surface. Groundwater is an important component of water resources. Due to its stable water volume and good water quality, it is one of the important water sources for agricultural irrigation, industry, mining and cities.

[0003] Before groundwater is exploited and used, it is necessary to test the groundwater to see whether it meets the use standards. When testing the groundwater, it is necessary to sample the groundwater for testing, so a groundwater sampling device is needed.

[0004] The existing groundwater sampling device needs to be fixed on the ground and then the water sampling component is extended into the ground for sampling. However, for more accurate detection, it is necessary to sample different positions in the same area. When the existing sampling device needs to be changed for sampling, it is necessary to release the device from the ground and move the entire device before fixing it for use. Therefore, it is not convenient and flexible to sample different underground positions. Utility Model Content

[0027] The working principle of the utility model is as follows: the fixed frame 2 is moved to the sampling top where sampling is required by the pulley 4, and then several rocking wheels 28 are rotated respectively to make the fixed screw 26 rotate and drive the fixed cone 27 to descend, and the fixed cone 27 is inserted into the ground to fix the fixed frame 1 for use, and then the two transmission rods 8 can be driven to rotate by the double-axis motor 7, so that the two first bevel gears 9 rotate and drive the two second bevel gears 10 to rotate, so that the two lifting screws 4 rotate at the same time, so that the lifting plate 6 slides and descends on the limit rods 5 on both sides, so that the sampling rod 20 descends and extends into the ground. At this time, the groundwater will enter the water collection chamber 21 through the water inlet 22, and the water quality will be filtered through the filter screen 23. After the sampling is completed, the output ends of the double-axis motor 7 at both ends are Reverse the rotation to raise the lifting plate 6 to take out the sampling rod 20, and then unscrew the bottom cover 24 to remove the water in the water collecting chamber 21 for testing. However, when it is necessary to sample groundwater at different positions in this area, according to the sampling position required, the servo motor 14 drives the translation screw 11 to rotate, so that the slide plate 13 slides left and right on the slide bar 12, thereby moving the translation plate 15 to adjust the sampling rod 20 left and right. At the same time, the servo motor 2 19 can drive the translation screw 2 16 to rotate, so that the slide plate 2 18 slides back and forth on the slide bar 2 17, so that the sampling rod 20 can be moved back and forth for adjustment.
