Description

Technical Field

[0001] This application relates to the technical field of water quality sampling, and particularly to a water quality sampling mechanism. Background Art

[0002] Currently, in order to optimize the living environment, the water environment is usually monitored. The water environment refers to the environment where water is formed, distributed, and transformed in nature. The safety monitoring of the water environment is a process of monitoring and measuring the types of pollutants in the water body, the concentration of various pollutants, and their changing trends, and evaluating the water quality status. Before detecting the water quality, a water quality sampling mechanism is required to sample the water body.

[0003] In the patent document with the published publication number CN217605375U, a river water quality sampling device with adjustable depth is provided. In this published patent document, the sampling pipe is adjusted to a suitable position through a telescopic sleeve and a telescopic column, and water quality sampling can be carried out at different depth positions of the river. Moreover, the scale lines on the surface of the telescopic sleeve and the telescopic column can improve the accuracy of the water quality sampling depth, thereby improving the accuracy of the water quality measurement results, and solving the problem that the previous river water quality sampling devices are difficult to detect river water at different depths; however, this sampling device can only perform water quality sampling at one depth detection point at a time. When collecting water samples at different depths in the same water area, multiple samplings are required, and the operation is too cumbersome. Therefore, an improvement is now made to a water quality sampling mechanism. Utility Model Content
