Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water quality rapid detection tube. Background Art

[0002] Water quality testing is the process of monitoring and measuring the types of pollutants in water, the concentrations of various pollutants and their changing trends, and evaluating the water quality. The monitoring scope is very wide, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage.

[0003] After searching, the patent (application number: 202322016812.2) discloses "a water quality rapid detection cylinder". The device can pour a certain amount of sewage into the beaker, and then the hydraulic cylinder can push the beaker to rise and fall, so that the detection probe set by the water quality detector can be inserted into the beaker to detect the sewage. The beaker can be easily fixed on the storage rack and easily disassembled and assembled, so that it is easy to replace different beakers for multiple tests, thereby improving the detection efficiency and accuracy. However, the device has the following problems in actual operation:

[0004] First, in the process of testing water quality in this device, the operator needs to pay attention to the water quality testing at all times, and the operator needs to cooperate in placing different beakers on the storage rack, which is more dependent on manual operation and affects the detection efficiency;

[0005] In addition, the device does not have a structure for cleaning the detection probe. The detection probe cannot be cleaned in time after each detection. In the subsequent detection process, the original liquid remaining on the detection probe will mix with other water quality, causing inaccurate water quality detection results. Utility Model Content
