The upper partition 18 is fixedly connected to the interior of the upper float 15.

[0029] Specifically, the control panel 3 is used to control the operation of the peristaltic pump 4 and the drive motor 11, which is convenient for users to perform remote control. The peristaltic pump 4 is used to extract water samples from the water intake pipe 2 into the inside of the body 1, and can accurately control the sampling metering. Two sets of limit balls 5 are used to control the sampling range. The lower float 6 and the upper float 15 can make the water intake pipe 2 float in the water, thereby controlling the sampling depth. The external thread 7 and the internal thread 17 are threaded to connect the lower float 6 and the upper float 15. The fixed block 10 is used to locate the position of the drive motor 11, which is convenient for accurate installation and disassembly. The drive motor 11 can drive the roller 12 to rotate by rotating, thereby adjusting the position of the water intake pipe 2 by rotating the roller 12, thereby achieving the effect of adjusting the different sampling depths of the water intake pipe 2.

[0030] Reference Figure 1-3 , fixed blocks 19 are provided on both sides of the drive motor 11, and a snap ring 20 is provided on the top of the drive motor 11. The snap ring 20 is clamped on the top of the fixed block 19, and the fixed block 19 is fixedly connected to the top of the lower partition 9. The drive motor 11 is electrically connected to the remote controller 13 through a wire, and the remote controller 13 is connected to the control panel 3 through an electrical signal. A protective cover 21 is fixedly installed on the top of the remote controller 13, and a rubber sealing ring 23 is provided on the surface of the lower float 6 and the upper float 15. The thickness of the rubber sealing ring 23 is two millimeters, and the peristaltic pump 4 is electrically connected to the control panel 3 through a wire.

[0031] Specifically, the snap ring 20 can be connected to the fixed block 19 to fix the drive motor 11. At the same time, the snap connection facilitates installation and disassembly. The remote controller 13 is connected to the control panel 3 by electrical signals, which can facilitate the user to control the drive motor 11 at a remote distance, thereby facilitating the adjustment of the sampling depth. The protective cover 21 is used to protect the remote controller 13, and the rubber sealing ring 23 is used to improve the sealing of the connection position between the upper float 15 and the lower float 6.

[0032] Reference Figure 2-4 The external thread 7 is threadedly connected to the internal thread 17, and through grooves 22 are opened on both sides of the surface of the through pipe 8. One side of the surface of the roller 12 passes through the through groove 22 and is located inside the through pipe 1 8. The through pipe 1 8 is connected to the through pipe 2 16. The water intake pipe 2 is set inside the through pipe 1 8 and the through pipe 2 16. The lower float 6 and the upper float 15 are both located between the two groups of limit balls 5.

[0033] Specifically, the external thread 7 and the internal thread 17 are threadedly connected, which makes it easy for users to assemble the upper float 15 and the lower float 6, thereby improving the convenience of installation. The roller 12 is connected to the water intake pipe 2 by a through groove 22 passing through one side of the surface of the roller 12 and located inside the through pipe 8, so that the roller 12 can be in contact with the water intake pipe 2, thereby facilitating the adjustment of the sampling depth of the water intake pipe 2. The upper float 15 and the lower float 6 are both located between the two groups of limit balls 5, which are used to control the range of the sampling depth of the water intake pipe 2.

[0034] Working principle: When in use, first place one end of the water intake pipe 2 into the water area where sampling is required. The lower float 6 and the upper float 15 use buoyancy to keep the sampling end of the water intake pipe 2 at a certain depth in the water body. Then operate the control panel 3 to start the peristaltic pump 4. When the peristaltic pump 4 is running, it continuously squeezes the water intake pipe 2. The water intake pipe 2 extracts water samples from the water area into the body 1 for storage. When it is necessary to extract water samples of different depths, operate the control panel 3 to start the drive motor 11. The control panel 3 will output a signal to the remote controller 13. Then the remote controller 13 controls the drive motor 11 to rotate. When the drive motor 11 rotates, it also drives the roller 12 to rotate. When the roller 12 rotates, it contacts the water intake pipe 2, thereby moving the water intake pipe 2 along the direction of rotation of the roller 12 inside the through pipe 1 8 and the through pipe 2 16. At this time, the water intake end of the water intake pipe 2 is adjusted in the water body, and the distance between the two sets of limit balls 5 is moved to change the range of the sampling depth of the water intake pipe 2.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
