[0028] In this embodiment, as a further optimization solution, please refer to Figure 1 The sampling cover 3 is slidably connected to the sliding member; the sampling cover 3 can move up and down at the sliding member, and after the support plate 7 is rotated to a horizontal state, the pull block 6 cannot move, that is, the sliding member cannot move, and the sampling cover 3 can move up and down to ensure that the bottom of the sampling cover 3 can fit with the support plate 7; and a spring is installed between the sliding member and the sampling cover 3 to provide a downward force on the sampling cover 3, so that the sampling cover 3 and the support plate 7 can fit tightly; and the sliding member can be removed from the slide groove 2, and the sampling cover 3 can be replaced; and the isolation cover 4 is also detachably connected to the handle 1, so that the isolation cover 4 can be removed for replacement.

[0029] In this embodiment, as a further optimization solution, please refer to Figure 1 The annular cover is slidably sleeved on the outside of the isolation cover 4 or the annular cover is slidably inserted into the isolation cover 4, and the annular cover is fixed with bolts; by moving the annular cover, the height of the isolation cover 4 can be changed to adapt to waters of different depths.

[0030] In this embodiment, as a further optimization solution, please refer to Figure 5 , the surface of the support plate 7 is provided with holes; so that the support plate 7 can pass through, so that during the rotation of the support plate 7, the disturbance caused by the support plate 7 to the water area is further reduced.

[0031] It should be noted that the working method of the sampling module is to hold the handle 1 and insert the isolation cover 4 vertically into the water area so that the isolation cover 4 separates the sampling area from the outside water area (the top of the isolation cover 4 is higher than the water surface); then insert the sampling cover 3 into the water area so that the sampling cover 3 enters the interior of the isolation cover 4; in the process of the isolation cover 4 moving downward, the sliding part will move downward until it contacts the pull block 6, and move the pull block 6 downward, pulling the pull rope and rotating the support plate 7 to a horizontal state, and the bottom end of the sampling cover 3 will contact the support plate 7 to seal the bottom of the sampling cover 3 (the sampling cover 3 and the support plate 7 form a device for holding water samples); then pull the handle 1 to move the isolation cover 4 and the sampling cover 3 out of the water area to complete the sampling work.

[0032] In this embodiment, as a further optimization solution, please refer to Figure 4 、 Figure 5 and Figure 6 , a groove 10 is provided on the support plate 7, a magnet part 11 is provided in the groove 10, and a magnetic metal part is provided at the bottom of the sampling cover 3 (a magnetic metal part refers to a metal part that can be magnetically adsorbed, such as iron); an annular air bag 12 is sleeved on the bottom outer side of the sampling cover 3, and a pressing air bag 13 is provided at the bottom of the sampling cover 3, which is connected to the annular air bag 12; when the bottom of the sampling cover 3 contacts the support plate 7, the bottom of the sampling cover 3 will enter the groove 10, and the magnet part 11 can adsorb the magnetic metal part to fix the sampling cover 3 on the support plate 7; and the pressing air bag 13 will contact the inside of the groove 10, squeeze the pressing air bag 13, and squeeze the air therein into the inside of the annular air bag 12, so that the annular air bag 12 is inflated and contacts the inner wall of the groove 10, and the contact area between the sampling cover 3 and the support plate 7 is sealed, so that the water sample stored in the sampling cover 3 will not leak.

[0033] In this embodiment, as a further optimization solution, please refer to Figure 4 and Figure 6 When the sampling cover 3 is in contact with the supporting plate 7, the movable member 14 is pushed toward the inside of the mounting groove, and the connecting rope is pulled to move the baffle 8 and block the top of the sampling cover 3. In the process of moving the sampling cover 3 upward with the handle 1, the water inside the sampling cover 3 will not leak accidentally. At the same time, the sample in the sampling cover 3 is separated from the outside world, so that when the sampling cover 3 is removed from the water, the water in other areas will not be exchanged again with the water inside the sampling cover 3, thereby ensuring the accuracy of the sampling cover 3.

[0034] In this embodiment, as a further optimization solution, please refer to Figure 4 and Figure 6 When the sampling cover 3 moves up, the water will press the stopper 16 downward, and due to the action of the limiter, the stopper 16 will completely seal the through hole 15, thereby ensuring the sealing effect of the baffle 8 on the top of the sampling cover 3.

[0035] In this embodiment, as a further optimization solution, please refer to Figure 1 and Figure 4 A spring member is provided between the sliding member and the slide groove 2, and a winding mechanism 5 is provided at the end of the handle 1 away from the isolation cover 4 (the winding mechanism 5 includes a box body and a winding rod rotatably installed inside the box body); a connecting rope is wound around the winding mechanism 5 (that is, the connecting rope is wound around the outer wall of the winding rod, the winding rod extends to the outside of the box body, and is fixed with a positioning bolt), and the end of the connecting rope is connected to the sliding member; loosen the fixation of the winding rod, release the connecting rope from the outer wall of the winding rod, so that the tension on the sliding member disappears, and under the action of the spring member, the sliding member will move with the sampling cover 3 toward the inside of the isolation cover 4, making it convenient to move the sampling cover 3 into the isolation cover 4.

[0036] In this embodiment, as a further optimization solution, please refer to Figure 4 and Figure 7 An annular baffle 9 is slidingly provided on the isolation cover 4 (the annular baffle 9 is slidably inserted into the isolation cover 4 or the annular baffle 9 is slidably sleeved on the outside of the isolation cover 4 or an annular groove is opened above the isolation cover 4, and the annular baffle 9 is slidably inserted into the annular groove), and a floating plate 17 is provided on the annular baffle 9 (the floating plate 17 is made of plastic foam); when the isolation cover 4 is inserted into the water area, the floating plate 17 will float on the water surface, so that the top of the annular baffle 9 is always on the water surface, ensuring that the isolation cover 4 separates the sampling area from the outside water area.

[0037] In this embodiment, as a further optimization solution, please refer to Figure 7 and Figure 8A placement groove 20 is provided on the side wall of the float 17, and an expansion plate 18 is slidably provided in the placement groove 20 (the expansion plate 18 is made of the same material as the float 17); an extrusion airbag 21 is provided in the placement groove 20, and the extrusion airbag 21 is located on the inner side of the expansion plate 18. An inflatable airbag 19 is provided on the float 17, and the inflatable airbag 19 is connected to the extrusion airbag 21; when the float 17 sinks into the water, the water will squeeze the inflatable airbag 19, and introduce the air inside it into the extrusion airbag 21, causing it to inflate and expand, pushing the expansion plate 18 outward, increasing the contact area between the expansion plate 18 and the float 17 and the water area, thereby increasing the buoyancy of the float 17, so that the top of the annular baffle 9 is always above the water surface.
