Description

Technical Field

[0001] The utility model relates to the technical field of water sample detection, in particular to a water body total phosphorus detection device. Background Art

[0002] When testing water for total phosphorus, reagents need to be added to the water sample, then vibrated and mixed, and then the total phosphorus test can be performed after the mixing is completed.

[0003] The Chinese patent with publication number CN116242980A discloses a total phosphorus detection device for water bodies, which relates to the field of water sample detection technology, including a driving chamber, the top of which is fixedly connected to an operating chamber, the top of which is fixedly connected to a containing chamber, one side of which is connected to a water inlet pipe, and the water inlet pipe is located at the top of the operating chamber, and the other side of which is connected to a water outlet pipe, and the water outlet pipe is located at the bottom of the operating chamber. The present invention starts a servo motor through a vibration mechanism, drives a driving column to rotate, and drives multiple cams to rotate around the driving column at the same time. Under the action of the cam, the guide rod performs longitudinal reciprocating motion to drive the support rod at the top of the guide rod to vibrate, and then drives the vibration pad to vibrate. Since the surface of the vibration pad is made of soft material, it is conducive to promoting the mixing of the sample solution and the reagent inside the test tube, so that the substance containing phosphorus in the sample solution is decomposed, thereby facilitating a more accurate detection of the total phosphorus in the sample solution.

[0004] The above-mentioned total phosphorus detection device for water body starts the servo motor to drive the driving column to rotate, so as to drive multiple cams to rotate around the driving column at the same time. Under the action of the cam, the guide rod performs longitudinal reciprocating motion to drive the support rod at the top of the guide rod to vibrate, thereby driving the vibration pad to vibrate and mix the test tube. However, this vibration method requires that each test tube must be equipped with a cam, a guide rod, a support rod and a vibration pad, which makes the manufacturing cost high. At the same time, the water in the water pipe is easy to spill out during vibration, and there is a lack of effective sealing structure for sealing. Utility Model Content
