A control pipe 2 is fixedly connected to the lower center of the floating box 1. An air pump 3 is fixedly installed at the center of the interior of the floating box 1, which can effectively create a pressure difference between the left and right ends of the pressure chamber 10, reducing sampling time. A main pipe 4 is fixedly connected to the input end of the air pump 3. A first branch pipe 5 is fixedly connected to the upper left end of the main pipe 4. A manual control valve 6 is fixedly installed on the first branch pipe 5, which can make the pressure at the right end of the pressure chamber 10 consistent with the atmospheric pressure.

Several second branch pipes 8 are fixedly connected to the right side of the control pipe 2. The right side of the second branch pipes 8 passes through the left side of the main pipe 4 and communicates with the interior of the main pipe 4.
[0020] Specifically, several partition plates 9 are fixedly connected inside the control pipe 2, forming a pressure chamber 10 between the inside of the control pipe 2 and the adjacent partition plates 9. Several water inlet pipes 11 are fixedly connected to the left side of the control pipe 2, which can effectively flow into water bodies of various depths. A first solenoid valve 12 is fixedly installed at the left end of the water inlet pipe 11. A sampling bottle 13 is threadedly connected to the lower right end of the water inlet pipe 11 to sample water bodies of different depths. A slide plate 14 is slidably connected to the left side of the inside of the control pipe 2. The right side of the slide plate 14 is slidably connected to the left side of the partition plate 9. Several connecting holes 15 are opened through the right side of the slide plate 14. The left end of the connecting hole 15 is connected to the inside of the water inlet pipe 11. The front end of the slide plate 14 passes through the inside of the control pipe 2 and is fixedly connected to a handle 16 for easy installation and removal of the slide plate 14.
[0021] Specifically, a pressure control plate 17 is slidably connected inside the pressure chamber 10. A rubber gasket 18 is fixedly connected to the left side of the pressure control plate 17 to prevent water from flowing to the right side of the pressure control plate 17. A telescopic rod 19 is fixedly connected to the center of the right side of the pressure control plate 17. The right side of the telescopic rod 19 is fixedly connected to the right side of the inside of the control pipe 2. A spring 20 is sleeved on the surface of the telescopic rod 19. The left end of the spring 20 is fixedly connected to the right side of the pressure control plate 17, and the right end of the spring 20 is fixedly connected to the inner wall of the right side of the control pipe 2.

[0022] Working principle: Place the float box 1 at the sampling position. After the control tube 2 is submerged in the water, open the first solenoid valve 12 and start the air pump 3. At this time, the manual control valve 6 and the second solenoid valve 22 are closed. The pressure at the right end of the pressure chamber 10 decreases, and the pressure control plate 17 moves to the right. Correspondingly, water at various depths accelerates into the inlet pipe 11 and flows into the sampling bottle 13. After the sampling bottle 13 completes sample collection, close the air pump 3 and the first solenoid valve 12, remove the float box 1 and the control tube 2 from the water, disassemble each sampling bottle 13 to complete sample collection, remove the fixing bolt 24, remove the slide plate 14, and open the manual control valve 6 and the second solenoid valve 22 at the same time. The pressure on both sides of the pressure control plate 17 returns to atmospheric pressure. Under the elastic force of the spring 20, the pressure control plate 17 returns to the left end of the pressure chamber 10. Part of the water accumulated inside the control tube 2 is discharged from the installation position of the slide plate 14, and part of it flows to the bottom of the control tube 2 and is discharged from the drain pipe 21.
