[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 - Figure 5 As shown, in this embodiment, in order to complete the collection of groundwater samples from different depths of water layers at one time through the sampling mechanism 2 to improve the sampling efficiency of groundwater, the specific use principle of the sampling mechanism 2 is as follows:

[0022] The vertical board 1 is placed into the sampling hole drilled in the ground through the handle 3 at the top of the vertical board 1, and a number of sampling tubes 21 arranged vertically at the front end of the vertical board 1 are immersed in the groundwater source, so that each sampling tube 21 is in a water layer at a different depth. The knob 15 on the top surface of the fixed plate 4 installed at the top of the back of the vertical board 1 is rotated, and the knob 15 will drive the rotating rod 14 installed at the top of the screw 13 to rotate in the bearing 6 installed in the mounting hole 5 opened on the top surface of the fixed plate 4, and the rotating rod 14 will drive the screw 13 to rotate on the bottom surface of the fixed plate 4. During the rotation of the screw 13, because the connecting plate 11 installed at the top of the back of the movable plate 10 is threadedly connected with the screw 13 through the screw hole 12 opened on the top surface, the connecting plate 11 will be screwed through the screw hole 12 opened on the top surface. The movable plate 10 moves upward along the screw rod 13 through the screw hole 12, and the connecting plate 11 will drive the movable plate 10 to move upward on the rear end wall of the vertical plate 1. In the process of the movable plate 10 moving upward, the connecting rod 17 installed on the front end wall of the movable plate 10 will be driven to move upward synchronously in the vertical opening 7 opened on the front end wall of the vertical plate 1, and the connecting rod 17 will drive the sealing cover 16 to move upward and leave from the top surface of the sampling cylinder 21 below. When the sealing cover 16 leaves the top surface of the sampling cylinder 21, it will drive the filter cylinder 18 installed on its bottom surface to move out from the inside of the sampling cylinder 21, and when the filter cylinder 18 gradually moves out to the upper outside of the sampling cylinder 21, the water sample of the corresponding depth water layer will enter the sampling cylinder through the plurality of filter holes 19 opened on the outer wall of the filter cylinder 18. 21, and cooperate with the use of the upper filter hole 19 to prevent the silt and impurities in the water layer sample from entering the sampling cylinder 21. However, after the sealing cover 16 drives the filter cylinder 18 to move upward, the filter cylinder 18 is not completely moved out of the sampling cylinder 21. After the sampling cylinder 21 completes the water sample collection operation, the knob 15 is rotated in the opposite direction to drive the screw 13 to rotate in the opposite direction through the rotating rod 14, and the connecting plate 11 moves downward along the screw 13 through the screw hole 12 and pushes the movable plate 10 to move downward. The movable plate 10 drives the sealing cover 16 to move downward through the connecting rod 17, so that the filter cylinder 18 enters the sampling cylinder 21, and the sealing cover 16 is completely pressed on the top surface of the sampling cylinder 21, and cooperates with the sealing ring 20 installed on the outside of the filter cylinder 18 on the bottom surface of the upper sealing cover 16 to be able to enter The water sample in the sampling tube 21 is sealed step by step until the knob 15 can no longer be rotated, and the entire device is lifted from the sampling hole. During the lifting process, not only can water samples from other water layers be prevented from entering the sampling tube 21, but also the water sample in the sampling tube 21 can be prevented from spilling out, thereby ensuring the accuracy of sampling. Finally, the knob 15 is rotated again to move the sealing cover 16 upward and the sealing cover 16 drives the filter cartridge 18 on the bottom surface to be completely removed from the sampling tube 21. After the T-shaped plug block 22 at the top of the rear end of the sampling tube 21 is removed from the T-shaped slot 9 on the front end wall of the fixing block 8 installed at the front end of the vertical plate 1, the sampling tube 21 containing the water sample can be removed from the front end of the vertical plate 1 to obtain groundwater samples of water layers at different depths.Thereby, the purpose of improving the water sample collection efficiency when monitoring groundwater quality is achieved, and the operation of water sample collection is simple, convenient and fast, and the collection operation of groundwater samples of different depths of water layers can be completed at one time without repeated operations.
