After the sampling tube and the extension tube enter the water, the rotating ring drives the first arc-shaped baffle and the second arc-shaped baffle at the bottom to rotate to the right and separate from the placement groove, so that the water flow in the water body can enter the sampling bottle through the bottle mouth to achieve sampling.

After the second motor operates, it drives the screw at the output end to rotate. When the screw rotates, the threaded sleeve is driven to move downward through the thread. When the threaded sleeve moves downward, the connecting rod is driven to open through the rotating seat. The four connecting rods push the four grippers to unfold through the rotating seat. At this time, the first motor is controlled to operate. After the first motor operates, it drives the protective cover at the output end and the second motor to rotate. The second motor drives the unfolded grippers to rotate. When the grippers rotate, the hard sludge is first stirred and crushed through their sharp ends, and then the grippers are inserted into the sludge. At this time, the second motor drives the connecting rod and the gripper to move through the screw, the threaded sleeve and the rotating seat, and shrinks inward until the four grippers are completely closed together and sealed closed by the side sealing gaskets, so that part of the sludge is grabbed and stored in the gripper when closed, thereby realizing the sampling of sludge.
[0019] Third, the present invention is provided with a water pump, a water pump pipe, a first filter screen, a bellows, a dosing pipe, a sponge board and a drug tube. The water pump is operated to draw water through the water pump pipe into the movable cover and the fixed cover. The water first passes through the first filter screen inside the movable cover for coarse filtration, and then passes through the two second filter screens in the fixed cover for fine filtration, so that the relatively clean water after filtration is sprayed out through the dosing pipe and the nozzle. The staff can control the nozzle to flush various positions on the sampling tube and the extension tube to flush away garbage impurities and sludge, so as to ensure that the sampling tube and the extension tube are neat and tidy, which is convenient for their storage. When cleaning agent needs to be added for cleaning, the cleaning agent is poured into the inside of the drug tube and sealed with a sealing cover. The cleaning agent in the drug tube slowly drips into the sponge board through the ground drip tube and soaks the sponge board. Then, the clean water flowing through the sponge board is mixed into cleaning agent water, so that when it is sprayed out through the nozzle, it has a special cleaning function and can chemically clean the pollutants remaining on the sampling tube and the extension tube.

[0026] Working principle: When the present invention is used, first determine the number and position of the sampling bottles 303 according to the depth of the water body to be sampled, and insert multiple sampling bottles 303 into the placement slots 301 at the corresponding positions according to different depth requirements. After insertion, the sampling bottles 303 are fixed to the placement slots 301, the sampling tube 1, and the extension tube 2 through the magnetic block 302. At this time, the rotating ring 307 is screwed, and the rotating ring 307 drives the first arc baffle 305 and the second arc baffle 310 at the bottom to rotate to the left and insert into the inner side of the limiting frame 306, and the bottle mouths 304 at the front ends of the multiple sampling bottles 303 and the placement slots 301 are sealed and blocked. Then the sampling device is debugged. After the staff moves with the ship to the designated sampling waters, the sampling tubes 303 are fixed to the placement slots 301 and the extension tubes 2. 1. The extension tube 2 is inserted into the water body. When it penetrates to a certain depth, the floating plate 4 can float on the water surface to enhance the stability of the sampling device. At this time, the rotating ring 307 is screwed again, and the rotating ring 307 drives the first arc baffle 305 and the second arc baffle 310 at the bottom to rotate to the right and separate from the placement groove 301. Then, the water flow in the water body can enter the sampling bottle 303 through the bottle mouth 304 to achieve sampling. After sampling, the rotating ring 307 drives the first arc baffle 305 and the second arc baffle 310 to rotate to the left to seal and cover the placement groove 301. During sampling, if it is necessary to extract silt at the bottom of the water body for testing, the second motor 604 is controlled to run. After the second motor 604 runs, it drives the screw rod 605 at the output end to rotate. The screw rod 60 When the screw sleeve 606 is rotated, the screw thread drives the thread sleeve 606 to move downward. When the screw sleeve 606 moves downward, the connecting rod 610 is driven to open through the rotating seat 609. The four connecting rods 610 push the four claws 611 to expand through the rotating seat 609. At this time, the first motor 601 is controlled to operate. After the first motor 601 operates, it drives the protective cover 603 at the output end and the second motor 604 to rotate. The second motor 604 drives the expanded claws 611 to rotate. When the claws 611 rotate, the hard sludge is first stirred and crushed by their sharp ends, and then the claws 611 are inserted into the sludge. At this time, the second motor 604 drives the connecting rod 610 and the claws 611 to move and shrink inward through the screw rod 605, the screw sleeve 606 and the rotating seat 609. Until the four grippers 611 are completely closed together and sealed by the side sealing gasket 612, so that part of the sludge is grabbed and stored in the grippers 611 when closed, and the sludge is sampled. After the sampling is completed, the sampling tube 1 and the extension tube 2 are drawn out of the water body. During the drawing process, for the placement slot 301 without the sampling bottle 303 installed, the water flow entering it falls through the drainage slot 308 on one side, and the water flows inside the multiple placement slots 301 are collected through the drainage slot 308 and finally discharged through the drain pipe 309. After the sampling tube 1 and the extension tube 2 are completely taken out, only the sample in the sampling bottle 303 exists. The sampling tube 1 and the extension tube 2 can be placed horizontally on the ground, and the first arc baffle 305 and the second arc baffle 310 are rotated to one side.The sampling bottle 303 can be directly taken out from the placement slot 301, which is convenient for taking, transferring and storing samples. At this time, the sealed shell 703 is fixed to the rear end of the sampling tube 1 through the snap block 701 and the snap frame 702, and then the sampling tube 1 is shallowly inserted into the water body so that the suction pipe 708 can contact the water flow. At this time, the water pump 704 is controlled to run after being energized by the outside. The water pump 704 runs through the suction pipe 708 to draw water into the movable cover 707 and the fixed cover 706. The water flow first passes through the first filter screen 709 inside the movable cover 707 for rough filtration, and then passes through the two second filter screens 710 in the fixed cover 706 for fine filtration, so that the relatively clean water after filtration can be filtered through the dosing The staff can control the nozzle 713 to flush various positions on the sampling tube 1 and the extension tube 2, flush away garbage impurities and sludge, etc., to ensure that the sampling tube 1 and the extension tube 2 are neat and tidy, which is convenient for their storage. When chemical cleaning agents need to be added for cleaning, the cleaning agents are poured into the inside of the reagent tube 715 and sealed with a sealing cover. The cleaning agent in the reagent tube 715 slowly drips into the sponge board 714 through the ground drip tube 716 and soaks the sponge board 714. The clean water flowing through the sponge board 714 is mixed into cleaning agent water, so that when it is sprayed out through the nozzle 713, it has a special cleaning function and can chemically clean the pollutants remaining on the sampling tube 1 and the extension tube 2.
