The water sample conveying mechanism 30 is located in the barrel 10, and the water sample conveying mechanism 30 can rotate around the axis of the barrel 10. The water sample conveying mechanism 30 can convey the water sample in the barrel 10 to the test tube on the fixing assembly. The driving mechanism is used to drive the water sample conveying mechanism 30 to rotate.

[0056] In this embodiment, the test personnel pour the water sample to be tested into the cylinder 10, arrange multiple test tubes on the fixed assembly, and arrange multiple test tubes around the cylinder 10. The water sample conveying mechanism 30 conveys the water sample to the corresponding test tube in the outer circle. Then, under the drive of the driving mechanism, the water sample conveying mechanism 30 rotates to face the next test tube, and the water sample conveying mechanism 30 conveys the water sample to it, which is more labor-saving than manual operation of water sample packaging.

[0057] In one embodiment, the water sample conveying mechanism 30 includes a conveying cylinder 31 , a conveying bridge 32 , a conveying funnel 33 and a lifting mechanism 34 .

[0058] An output port 311 is provided on an outer wall of one side of the upper end of the delivery tube 31 , and the lower end of the delivery tube 31 is immersed in the water sample.

[0059] One end of the conveying bridge 32 is connected to the outer wall of the conveying cylinder 31 , and a conveying channel 321 communicating with the output port 311 is formed on the conveying bridge 32 .

[0060] The delivery funnel 33 is located above the corresponding test tube on the fixing mechanism. The delivery funnel 33 is connected to the end of the delivery bridge 32 away from the delivery cylinder 31 and communicated with the output channel.

[0064] The circular bottom plate 341 is coaxially slidably arranged in the conveying cylinder 31, and the circular bottom plate 341 is dynamically sealed with the inner wall of the conveying cylinder 31. The water-blocking assembly is arranged on the circular bottom plate 341, and the water-blocking assembly can partially block the output port 311. The multi-stage electric push rod 342 is connected to the conveying cylinder 31, and its output end is connected to the circular bottom plate 341. Specifically, the upper end of the conveying cylinder 31 is connected to a mounting plate, the multi-stage electric push rod 342 is located in the conveying cylinder 31, the multi-stage electric push rod 342 is connected to the mounting plate, and the output end of the multi-stage electric push rod 342 is downwardly connected to the circular bottom plate 341.

[0065] In this embodiment, the lower end of the conveying cylinder 31 is immersed in the water sample, and the water sample enters the conveying cylinder 31 through the input port 312, and then the multi-stage electric push rod 342 drives the circular bottom plate 341 to rise. The water retaining component is immersed in the water sample from the beginning until the water retaining component is exposed to the surface of the water sample, and the water sample above the water retaining component flows back into the cylinder body 10. The water retaining component, the circular bottom plate 341 and the inner wall of the conveying cylinder 31 together constitute a temporary storage space for the water sample until the circular bottom plate 341 moves upward to the position of the output port 311, and the water sample on the circular bottom plate 341 flows out from the output port 311. The whole process completes the lifting of the water sample.

[0066] In one embodiment, a vertical clearance hole 343 is formed at the end of the circular bottom plate 341 close to the input port 312 .
