[0024] like Figure 1-Figure 4 As shown, this specific embodiment adopts the following technical scheme: it comprises an outer tank body 1, a sampling tube 2, a single chip microcomputer 3 and a water quality detector 4. The upper and lower sides of the inner part of the outer tank body 1 are divided into an equipment chamber and a sampling chamber by a partition.

[0025] It also contains:

[0026] A partition frame 5, wherein the partition frame 5 is fixedly arranged in the sampling tube 2, and the interior of the sampling tube 2 is divided into several liquid storage chambers by the partition frame 5, and a detection sealing mechanism 6 is arranged in the liquid storage chamber. Several liquid through holes are arranged on the side wall of the sampling tube 2 with equal fillets, and the liquid through holes are arranged in coordination with the liquid storage chamber. A liquid outlet guide bucket 15 is arranged below the several liquid outlets arranged on the side wall of the outer tank body 1 with equal fillets and coordinated with the liquid through holes, and the liquid outlet guide bucket 15 can provide outflow guidance for the groundwater sample flowing out of the liquid through hole;

[0027] The electric push rod 7 is a plurality of electric push rods 7, which are respectively fixedly arranged in the movable grooves opened above the top walls of the plurality of liquid-passing ports. The electric push rod 7 is electrically connected to the single-chip microcomputer 3. A sealing plate 8 is movably arranged in the liquid-passing port. The upper part of the sealing plate 8 is movably arranged in the movable groove. The output end of the electric push rod 7 is connected to the sealing plate 8. Slide blocks 14 are fixedly arranged on both side walls of the sealing plate 8. The slide blocks 14 are slidably arranged in the slide grooves opened on the side walls of the movable groove. The slide blocks 14 can provide auxiliary guidance for the up and down movement of the sealing plate 8, so that the movement process of the sealing plate 8 is more stable.

[0028] A fixing frame 9, wherein the fixing frame 9 is fixedly arranged on the upper part of the sampling tube 2, a winding rod 10 is arranged in the sampling chamber at the upper position of the sampling tube 2 through a bearing, and a driving motor 11 electrically connected to the single-chip microcomputer 3 is fixedly arranged on the left side of the outer tank body 1 through bolts, and the output shaft of the driving motor 11 is connected to the winding rod 10;

[0029] A pull rope 12, the pull rope 12 is wound on the winding rod 10, and the two ends of the pull rope 12 are respectively fixedly connected to the winding rod 10 and the fixing frame 9, and auxiliary ropes 16 are wound on the left and right sides of the winding rod 10, and the two ends of the auxiliary rope 16 are respectively fixedly connected to the winding rod 10 and the fixing frame 9. The auxiliary rope 16 can be used to maintain the state of the sampling tube 2 to prevent the sampling tube 2 from rotating and causing the water quality detector 4 to be unable to detect the groundwater in the sampling tube 2. A water depth detector 13 electrically connected to the single-chip microcomputer 3 is fixedly arranged at the lower part of the sampling tube 2;

[0030] The detection sealing mechanism 6 comprises:

[0031] A detection cylinder 6-1, wherein the detection cylinder 6-1 is fixedly arranged at the top wall opening of the liquid storage cavity, and a plurality of liquid inlets 6-2 are evenly distributed on the side wall of the detection cylinder 6-1;

[0032] The spring 6-3 is fixedly arranged in the detection tube 6-1, and a sealing top plate 6-4 is fixedly arranged on the upper end of the spring 6-3, and the sealing top plate 6-4 is arranged to be in conflict with the detection head on the water quality detector 4.

[0033] When using the utility model, the outer tank body 1 is pre-fixed at the detection wellhead of the groundwater, and the driving motor 11 is started to drive the winding rod 10 to rotate, so that the winding rod 10 drives the sampling tube 2 to move slowly downward into the well through the pull rope 12 and the auxiliary rope 16, and the detection head of the water quality detector 4 is separated from the interference with the sealing top plate 6-4. At this time, the spring 6-3 pushes the sealing top plate 6-4 upward, so that the sealing top plate 6-4 seals the upper opening of the detection tube 6-1, and then the depth of the groundwater where the sampling tube 2 is located can be detected by the water depth detector 13, and the sampling tube 2 can be sampled. After the sample tube 2 moves to the specified depth, the electric push rod 7 is started by the single chip computer 3, and the electric push rod 7 is shortened to drive the sealing plate 8 to move upward into the moving groove, so that the liquid port is opened. At this time, the groundwater will flow into the liquid storage chamber through the liquid port, and then the electric push rod 7 is started again to extend it to drive the sealing plate 8 to move downward, so that the sealing plate 8 can seal the liquid port. Then, the winding rod 10 can continue to rotate to make the sampling tube 2 lowered to a deeper depth, and the remaining liquid ports can be opened and closed by the above method to achieve sampling of groundwater at different depths;

[0034] After the groundwater sampling work is completed, the winding rod 10 is driven by the driving motor 11 to rotate in the opposite direction, and the winding rod 10 reels the pull rope 12 and the auxiliary rope 16, so that the sampling tube 2 moves upward, and in this process, the auxiliary rope 16 can limit the two sides of the sampling tube 2 to prevent the sampling tube 2 from rotating. After the sampling tube 2 moves into the outer tank body 1, the detection head of the water quality detector 4 can be inserted into the detection tube 6-1, and the sealing top plate 6-4 is pushed downward to compress the spring 6-3, and the liquid storage chamber The groundwater in the liquid storage chamber will also flow into the detection tube 6-1 through the liquid inlet 6-2, so that the water quality detector 4 can detect the water quality of the groundwater in each liquid storage chamber. When the staff needs to take out the groundwater in the detection tube 6-1 and take it to the laboratory for testing, the electric push rod 7 can be started to shorten and drive the sealing plate 8 to move upward, thereby opening the liquid port, so that the groundwater in the liquid storage chamber will flow to the outside through the liquid port. After that, the staff will place the sampling bottle below the liquid outlet guide bucket 15 to collect the groundwater.

[0035] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0036] 1. Through the cooperation of the partition frame 5, the detection sealing mechanism 6, the electric push rod 7, the sealing plate 8, the fixing frame 9, the winding rod 10, the driving motor 11, the pull rope 12 and the water depth detector 13, the detection and sampling of the groundwater quality at different depths can be realized, thereby improving the detection accuracy of the groundwater;

[0037] 2. Through the cooperation of the auxiliary rope 16, the two sides of the sampling tube 2 can be restricted to prevent the sampling tube 2 from rotating and deviating, which would cause the water quality detector 4 to be unable to detect the groundwater in the sampling tube 2.

[0038] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
