[0022] Please see Figure 1-5 The present invention provides the following technical solution: a portable stratified sampling device for water quality testing, including a mounting plate 1, an electric push rod 14 at the bottom of the mounting plate 1, an output end of the electric push rod 14 connected to a mounting frame 9, a plurality of water pumps 10 (up to four) mounted on one side of the mounting frame 9, the plurality of water pumps 10 being arranged vertically, an outlet pipe 11 connected to the output end of the water pump 10, a connecting pipe 8 connected to the input end of the water pump 10, a sampling cylinder 6 connected to one end of the connecting pipe 8, and the sampling cylinder 6 corresponding to the water pump 10, a switch operation plate 3 on one side of the top of the mounting plate 1, and the switch operation plate 3 being electrically connected to the water pump 10, a handle 2 on the top of the mounting plate 1, and four corresponding grooves 13 respectively opened on the other side of the mounting frame 9, a connecting square post 16 mounted on the surface of the sampling cylinder 6, and the connecting square post 16 being located inside the groove 13, a threaded post 18 at one end of the connecting square post 16, and a hexagonal ring 17 threadedly connected to the surface of the threaded post 18.

[0023] In this embodiment: a connecting cylinder 5 is provided on the top of the mounting bracket 9, and a bolt 12 is provided on one side of the connecting cylinder 5. One end of the bolt 12 passes through the connecting cylinder 5 and is threaded to a nut 4. By setting the bolt 12, the connecting cylinder 5 and the nut 4, the mounting bracket 9 is connected and fixed, thereby increasing the convenience of its installation.

[0024] In this embodiment: a limiting plate 15 is provided on the surface of the connecting square column 16, and the limiting plate 15 is located inside the mounting bracket 9.

[0025] In this embodiment, a threaded plug 21 is threadedly connected to the bottom of the sampling cylinder 6. A through hole 22 is provided at the bottom of the threaded plug 21, and the through hole 22 extends into the interior of the sampling cylinder 6. The threaded plug 21 is threadedly connected to the sampling cylinder 6, thereby increasing the sealing of the connection. When it is necessary to remove the sampled water inside the sampling cylinder 6, the threaded plug 21 is separated from the sampling cylinder 6, thereby facilitating the removal of the sampled water and increasing the convenience of use.

[0026] In this embodiment, a second connecting ring 19 is threadedly connected to the surface of the sampling cylinder 6. A protective filter cover 20 is provided at the bottom of the second connecting ring 19, and the protective filter cover 20 is located outside the threaded plug 21.

The second connecting ring 19 is threadedly connected to the sampling cylinder 6, thereby increasing the stability of the connection, making it easier to disassemble and clean, and increasing the convenience of later maintenance.

[0027] In this embodiment: a semi-circular rubber sheet 23 (two pieces that are in contact) is installed inside the through hole 22, and the semi-circular rubber sheets 23 are in contact with each other. By means of the semi-circular rubber sheets 23, the contact position is deformed by the suction force, allowing water to enter.

[0028] In this embodiment: a first connecting ring 7 is provided at the top of the sampling cylinder 6, and the first connecting ring 7 is threadedly connected to the connecting pipe 8.

[0029] In this embodiment: by setting a connecting square post 16, the connecting square post 16 is located inside the groove 13, thereby restricting and fixing the sampling cylinder 6 and increasing the stability of the installation. By setting a limiting plate 15 and rotating the hexagonal ring 17, the hexagonal ring 17 moves on the surface of the threaded post 18, thereby moving closer to the limiting plate 15 and driving it to move, so that the limiting plate 15 and the hexagonal ring 17 are in close contact with the mounting frame 9, thereby fixing the sampling cylinder 6 and increasing the stability of the installation.

[0030] The working principle and usage process of this utility model are as follows: After installation, the device is positioned at the sampling location, and the electric push rod 14 is activated, causing the mounting frame 9 to move downwards. Once in the water, the water pump 10 is controlled via the switch control panel 3 to draw water through the through hole 22 at the bottom of the threaded plug 21 into the sampling cylinder 6. The semi-circular rubber sheet 23, through suction, deforms at the contact point, allowing water to enter. When not in operation, the contact between the semi-circular rubber sheets 23 seals the water, preventing leakage and enhancing the sampling effect. Four sets of sampling cylinders 6 and water pumps 10 are configured to operate at different depths, allowing for water quality sampling at different depths and further improving the sampling effect. All electrical equipment in this device is powered by batteries, and all electric push rods are connected and controlled via a PLC control system.
