[0060] The storage box 211 is a rectangular hollow block for carrying the elastic diaphragm 212; the elastic diaphragm 212 is an elastic membrane made of rubber, fixed on the inner wall of the storage box 211, dividing the space inside the storage box 211 into two; the elastic diaphragm 212 divides the space inside the storage box 211 into a liquid bin 213 and an air bin 214; an inlet 215 and a suction port 216 are respectively provided on two opposite surfaces of the storage box 211, both of which are through holes; the inlet 215 is connected to the air bin 214, and the suction port 216 is connected to the liquid bin 213; a liquid inlet check valve 217 is fixed on the suction port 216, and the liquid inlet check valve 217 plays a role in ensuring that the water in the liquid bin 213 can only enter but not exit; the storage box 211 is also provided with an output hole, which is connected to the liquid bin 213 and is provided with an upper cover, which is closed under normal conditions and opened when pouring out the sample and cleaning the storage box 211.

[0072] Embodiment 2

[0073] Considering that the sampling ship sometimes needs to go to a river with a shallower water depth for sampling, in the above embodiment, due to the limitation of the structure of the sampling unit 210, the sampling unit 210 located at the bottom will generally extend into the water by 1.5 meters during the 15th to 18th sampling in a voyage. If sampling is to be carried out in waters with a water depth of less than 1.5 meters, it is necessary to reduce the number of samplings in a voyage (return to replace the sampling unit 210 after sampling about 12 times), or set up multiple sets of sampling components 200; the overall sampling process of the former method is more complicated, and the latter method is more expensive; if the sampling unit 210 is simply set to multiple rows, not only will the air path be complicated, but it will also be unfavorable for the movement of the shift pulley 234;

[0074] In view of the above problems, the embodiment of the present application optimizes and improves the structure of the storage box 211 on the basis of the above embodiment, so that the number of samplings in a single voyage and the applicability of sampling can be taken into account, specifically:

[0075] like Figure 6 and Figure 7 As shown, the storage box 211 includes a hard outer shell 270 and a built-in soft bag 275 made of rubber material fixed and tightly attached to the inner wall of the hard outer shell 270;

The first plate group 271 and the second plate group 272 are in the shape of a hollow quadrangular prism; four of the surfaces that are in close contact with each other on the first plate group 271 and the second plate group 272 are hinged together through two connecting bearing rods 273; the two connecting bearing rods 273 have the same axial direction and the same length direction as the surfaces in close contact with each other; the other surfaces in close contact with each other on the first plate group 271 and the second plate group 272 are provided with combined magnets, which are magnet sheets or magnet bars, and the combined magnets normally adsorb the first plate group 271 and the second plate group 272 together;

[0078] A plurality of hard outer shells 270 are closely attached and fixed together and arranged in a row; plate-shaped adsorption electromagnets 277 are positioned on the surfaces of the hard outer shells 270 that are closely attached to each other and fixed, and the adsorption electromagnets 277 are adsorbed together when powered.

[0079] In actual use:

[0080] When no sampling is performed, the storage box 211 is in a flat state;

[0081] When sampling is required, the shifting pulley 234 is controlled to slide along the shifting guide rail 236 to a position close to the storage box 211 where the sampling operation is to be performed; then the second quick-insertion connector 235 is controlled to be inserted into the first quick-insertion connector 218, so that the gas path is connected;

[0082] Thereafter, the pump air component 230 is controlled to pump air into the built-in soft capsule 275, so that the hard outer shell 270 is stretched open, changing from flat to square and being shaped under the magnetic force of the combined magnet; then the pump air component 230 is controlled to extract the gas in the air chamber 214 in the built-in soft capsule 275 for sampling.

[0083] Preferably, in order to facilitate the movement of the shift pulley 234, the sampling unit 210 close to the supporting column 220 is sampled first during sampling.

[0084] Preferably, in order to further ensure the accuracy of the samples taken, when the hull 100 travels to 2 to 3 meters close to the target sampling point, the sampling unit 210 to be used as a sampling container is controlled to expand and contract multiple times, thereby stirring the water flow to achieve self-cleaning.

[0085] Preferably, Figure 6 As shown, the storage box 211 is also provided with an air outlet one-way valve 237 and an air supply conduit 238. The air outlet one-way valve 237 is connected to the liquid tank 213 to ensure that the gas in the liquid tank 213 can only go out but not come in; the air supply conduit 238 guides the gas output from the air outlet one-way valve 237 to the liquid inlet one-way valve 217; in actual use, a certain amount of gas can be reserved in the liquid tank 213; when the built-in soft bag 275 expands, the gas in the liquid tank 213 is squeezed out and impacts the liquid inlet one-way valve 217, so as to achieve further cleaning.

[0086] Preferably, Fig.10 As shown, the built-in soft capsule 275 is detachably fixedly connected to the hard outer shell 270 through a combination component 276. After the sampling is completed, the built-in soft capsule 275 can be directly removed and transferred; the combination component 276 is a Velcro or a button.
