When the threaded rod 3 rotates, the movement of the connecting block 18 can be controlled by the thread on the surface, so as to realize the up and down movement of the sampling tube 11, a sampling tube 11 is fixedly connected to one side of the connecting block 18, a connecting pipe 13 is fixedly connected to the lower end surface of the sampling tube 11 and is communicated with, a baffle 17 is rotatably connected in the connecting pipe 13, and a baffle 17 is rotatably connected in the connecting pipe 13. A baffle 17 is arranged. When the baffle 17 is in contact with the connecting tube 13, the loss of water in the sampling tube 11 can be prevented. At the same time, when the water quality needs to be obtained, the first handle 14 can be used to control the flipping of the baffle 17 so that it no longer fits the inner wall of the connecting tube 13, thereby obtaining the water quality. Grooves 5 are symmetrically provided on both sides of the support frame 1, and limiting grooves 6 are symmetrically provided on both sides of the support frame 1. The grooves 5 are connected to the limiting grooves 6. A through hole 7 is provided in the groove 5, and a plug rod 8 is slidably connected in the through hole 7. By providing the plug rod 8, when the plug rod 8 is pushed into the deep mud, the positioning of the device is achieved.

[0022] Among them, a pull rod 9 is fixedly connected to the surface of the insertion rod 8, and a limit plate 10 is rotatably connected to the surface of the insertion rod 8. The limit plate 10 is overlapped in the limit groove 6. By setting the limit plate 10 and the limit groove 6, after adjusting the height of the insertion rod 8, the staff can rotate the limit plate 10 into the limit groove 6 to achieve the positioning of the insertion rod 8.

[0023] A first handle 14 is rotatably connected to the surface of the sampling tube 11 . The first handle 14 passes through the side wall of the sampling tube 11 and is fixedly connected to one side of the baffle 17 .

After adjusting the position, the limit plate 10 can be rotated to the direction of the limit groove 6 to limit the plug rod 8. At the same time, when the second handle 4 is turned, the position between the sampling tubes 11 can be adjusted, and the position of sampling can be adjusted according to different water levels to obtain the water quality of different water layers. At this time, the staff can turn the first handle 14 to flip the baffle 17 so that the surface of the baffle 17 is no longer in contact with the inner wall of the connecting pipe 13, so that the water quality can enter the sampling tube 11. At the same time, under the action of the drain valve 12, the atmospheric pressure in the lower space can be made smaller than the gas pressure and liquid pressure in the tube, so the flow rate of the water quality in the sampling tube 11 will be increased.
