Description

Technical Field

[0001] The utility model relates to the technical field of power line arrangement, in particular to a water pollution detection test tube. Background Art

[0002] Water pollution testing is the process of determining the types of pollutants in water, their concentrations, and their changing trends, thereby evaluating water quality. Testing covers a wide range of areas, including uncontaminated and contaminated natural water (rivers, lakes, oceans, and groundwater), as well as various industrial wastewaters. Test tubes are often used during this testing process.

[0003] Publication No. CN216778861U discloses a test tube for testing, which filters particles or impurities in a solution through a filter screen, and does not require other equipment for filtering. The operation is simple and the work efficiency is effectively improved. The particles and impurities are on the upper side of the filter screen, and then the adjustment ring is adjusted upward, and the adjustment ring drives the mounting plate to move up through the support rod, and the mounting plate drives the connecting rod to move up through the sealing cover, and the connecting rod drives the filter screen to move up, and the filter screen is adjusted out of the test tube body, and the filter screen can be cleaned. The cleaning is convenient and the operation is simple. Then the adjustment ring is adjusted downward, and the adjustment ring drives the mounting plate to move down through the support rod, and the mounting plate drives the sealing cover to move down until the sealing cover is in close contact with the upper end of the test tube body. At this time, the test tube body is in a sealed state for subsequent testing. However, the existing technology still has defects:

[0004] 1. The upper end of the existing filter screen is provided with a connecting rod, a sealing cover, a support rod and a mounting plate, which not only blocks the test tube opening at the upper end of the test tube, but also cannot be disassembled, making it difficult for testers to add sewage samples and reagents into the test tube, affecting the detection efficiency.

[0005] 2. In the prior art, when the test tube body is placed inside the test tube sleeve, most of the test tube is wrapped and blocked, making it impossible for the test personnel to observe the changes of the sewage test sample in the test tube in real time, thus affecting the test effect.
