[0029] Specifically, the water sample enters the water collector 1 from the water inlet 4. As the pressure piston 5 moves upward, the air is discharged into the air bag 6 through the exhaust port 3 and the air pipe 7, so that the air bag 6 becomes larger and wraps the outer side of the water inlet 4, so that the shallow water sample cannot enter the water collector 1 when floating, thereby improving the work efficiency of the staff and meeting the needs of users.

[0030] Reference Figure 1 and Figure 2 The lifting mechanism 2 includes a workbench 201, a rotating rod 205 is fixedly connected to the inner middle part of the workbench 201, a lifting rod 206 is rotatably connected to the middle part of the rotating rod 205, a U-shaped plate 212 is fixedly connected to the left end of the lifting rod 206, a second motor 215 is fixedly connected to the front side of the U-shaped plate 212, an output end of the second motor 215 passes through the U-shaped plate 212 and is fixedly connected to a third rotating wheel 213, a second pull rope 214 is fixedly connected to the bottom of the third rotating wheel 213, and a bottom end of the second pull rope 214 is fixedly connected to the top of the first ring 9, the workbench 201 also includes an arc plate 208, the inner middle part of the workbench 201 is fixedly connected to the arc plate 208, A groove 209 is provided on the inner side of the arc plate 208, and a moving block 207 is slidably connected inside the groove 209. The left side of the moving block 207 is fixedly connected to the right end of the lifting rod 206. The first motor 202 is fixedly connected to the right end of the bottom front side of the workbench 201. The output end of the first motor 202 passes through the workbench 201 and is fixedly connected to the first rotating wheel 203. The left end of the lower middle part of the inner side of the workbench 201 is rotatably connected to the second rotating wheel 204. The right end of the bottom of the lifting rod 206 is fixedly connected to the second ring 210. The outer wall of the second ring 210 is fixedly connected to the first pull rope 211. The end of the first pull rope 211 is fixedly connected to the middle of the first rotating wheel 203.

[0031] Specifically, the second motor 215 works to drive the third rotating wheel 213 to rotate, and pulls the second pull rope 214. At this time, the first ring 9 and the protective frame 8 rise, and the first motor 202 works to drive the first rotating wheel 203 to rotate, and pulls the first pull rope 211. At this time, the rotating rod 205 rotates, the right end of the lifting rod 206 slides downward, and the left end of the lifting rod 206 moves upward, which is convenient for recovering the sampler. Sampling at different depths can also be performed by adjusting the length of the second pull rope 214, so as to have a more comprehensive understanding of the vertical structure of the water body and the dynamics of the ecosystem.

[0032] Reference Figure 1 A counterweight 10 is fixedly connected to the middle of the protection frame 8, a switch 11 is fixedly connected to the front side of the workbench 201, and moving wheels 13 are fixedly connected to the four corners of the bottom of the workbench 201;

[0033] Specifically, the counterweight 10 can effectively allow the protection frame 8 and the water extractor 1 to sink into deep waters, and the moving wheels 13 at the bottom of the workbench 201 can make the workbench 201 easy to move.

[0034] Reference Figure 1 , the switch 11 is electrically connected to the first motor 202 and the second motor 215 respectively, and a protective cover 12 is disposed on the outer side of the first motor 202 and the second motor 215;

[0035] Specifically, the switch 11 can effectively control the operation of the first motor 202 and the second motor 215, and the protective cover 12 can effectively prevent the motors from being damaged by collision during transportation.

[0036] Working principle: When sampling deep water samples, air must be filled into the water sampler 1 first, so that the piston 5 is at one-third of the height of the water sampler 1. When the predetermined depth is reached, the water sample enters the water sampler 1 from the water inlet 4. Because the pressure piston 5 rises, the gas inside the water sampler 1 is discharged through the exhaust port 3, and the air bag 6 is inflated through the air pipe 7. The air bag 6 will swell and wrap the water inlet 4 due to inflation. At this time, when the water sampler 1 is recovered, the shallow water sample will not enter the water sampler 1, thereby improving the work efficiency of the staff and meeting the needs of users. When the sampler needs to be recovered, the second motor 215 is driven by the switch 11. The first pull rope 214 is pulled back to retract the water collector 1. The first ring 9 at the bottom of the second pull rope 214 rises, causing the water collector 1 to float on the water surface. At this time, the first motor 202 is operated to pull the first pull rope 211, driving the rotating rod 205 to rotate. At this time, the right end of the lifting rod 206 is slidably connected to the arc plate 208, and the right end of the lifting plate moves downward, so the left end of the lifting rod 206 moves upward, driving the water collector 1 below to retract. By adjusting the length of the second pull rope 214, water samples at different depths can be obtained for analysis and comparison, so as to have a more comprehensive understanding of the vertical structure of the water body and the dynamics of the ecosystem.
