[0026] A sample storage assembly is also provided on the top of the mounting plate 1, and the sample storage assembly includes a placement plate 8 rotatably mounted on the top of the mounting plate 1, the placement plate 8 is located on the outside of the fixing rod 2, and a plurality of groups of limiting openings 9 are opened on the surface of the placement plate 8, and sample tubes 10 are placed inside the limiting openings 9.

[0027] Among them, through the placement tray 8, multiple sample tubes 10 can be placed on the placement tray 8, the position of the sample tube 10 can be adjusted by rotating the placement tray 8, and the connecting tube 7 can be docked with the sample tube 10 by moving the limit plate 5, so that the water quality of multiple positions can be sampled and put into different sample tubes 10 during one working process through the sampling component, thereby greatly improving the efficiency of water quality monitoring sampling.

[0028] In addition, the opening and closing of the corresponding water inlet pipe 22 can be controlled by controlling the switch of the solenoid valve 21, and the number of sample tubes 10 in the same row is two, that is, it is convenient to conduct comparative experiments when sampling water quality at different positions at the same depth.

[0029] Also, see Figure 2 and Figure 3 A limiting assembly for limiting the limiting disk 5 is also provided on the surface of the fixed rod 2. The limiting assembly includes a first magnetic ring 12 and a second magnetic ring 11 fixedly mounted on the surface of the fixed rod 2. The limiting disk 5 is located between the first magnetic ring 12 and the second magnetic ring 11. Magnetic blocks 13 are fixedly mounted on the top and bottom of the limiting disk 5. The two magnetic blocks 13 are embedded in the inner wall of the limiting disk 5. The magnetic force of the first magnetic ring 12 and the upper magnetic block 13 attracts each other, and the magnetic force of the second magnetic ring 11 and the lower magnetic block 13 attracts each other.

[0030] Among them, by providing the first magnetic ring 12, the two magnetic blocks 13 and the second magnetic ring 11, it is convenient to limit the limiting plate 5, thereby facilitating the removal and adjustment of the sample tube 10, thereby improving the convenience of the new type.

[0031] See also Figure 3 In this embodiment, the top of the water inlet pipe 22 is flush with the inner bottom wall of the diverter box 4, and the solenoid valve 21 is embedded in the inner bottom wall of the diverter box 4.

[0032] Among them, through the above-mentioned arrangement, the water inside the diverter box 4 can completely enter the inside of the water inlet pipe 22.

[0033] In this embodiment, the limiting openings 9 are evenly distributed on the surface of the placement plate 8, and the number of each group of limiting openings 9 is two.

[0034] It should be noted that during the water quality monitoring process, in order to facilitate comparative experiments, the number of limit ports 9 in the present device is preferably two per group.

[0039] Among them, the starting motor 15 drives the winding drum to rotate so as to adjust the length of the second hose 18, and the sampling head 20 is placed in the water to be sampled. Under the action of the counterweight block 19, the sampling head 20 will sink, and after reaching the specified position, the water pump 16 is started to sample the water quality.

[0040] When the present embodiment is in use, the sample tube 10 is placed inside the placement tray 8, and the limit plate 5 is slid. When the magnetic block 13 below is magnetically connected to the second magnetic ring 12, the two connecting tubes 7 are docked with the sample tube 10 below them, and the motor 15 is started to drive the winding drum to rotate so as to adjust the length of the second hose 18. The sampling head 20 is placed in the water to be sampled. Under the action of the counterweight block 19, the sampling head 20 will sink. After reaching the specified position, the water pump 16 is started to sample the water. The water will pass through the second hose 18, the sampling tube 17, the diversion box 4, the water inlet pipe 22, the first hose 6 and the connecting pipe 7 in sequence. Enter the interior of the sample tube 10 to complete the sampling; when sampling is required at another position, slide the limit plate 5 upward so that the upper magnetic block 13 is adsorbed and connected with the first magnetic ring 11. At this time, the limit plate 5 is limited, and then the placement plate 8 is rotated to adjust the position of other sample tubes 10 to below the connecting tube 7. Repeat the above operation to sample at other positions. At the same time, the opening and closing of the corresponding water inlet pipe 22 can be controlled by controlling the switch of the solenoid valve 21. The number of sample tubes 10 in the same row is two, that is, it is convenient to conduct comparative experiments when sampling water quality at different positions at the same depth, thereby greatly improving the efficiency of water quality monitoring sampling.
