Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection, in particular to a sampling device for water quality detection. Background Art

[0002] Water quality testing mainly involves sampling water resources in order to better understand the situation in the area. Generally, water samples from the area are extracted through sampling devices. There are differences between sampling devices according to the different samples. Most water quality testing sampling devices are water samplers or sampling cylinders. However, these two sampling devices have certain limitations. Sampling cylinders and samplers are not convenient to adjust according to the depth of the water source. They need to be sampled first and then stored. They are cumbersome to use and not convenient to carry.

[0003] After searching, it was found that the publication number is CN220322833U, and the name is a water quality sampling device for water quality detection. The application proposed a water quality sampling device for outdoor carrying with patent number CN201721687431.5 in the prior art. However, due to the different components of some water at different depths, the device can only sample water samples at a specific depth, which is not convenient for adjusting the sampling depth of the device according to the actual situation, and it is not convenient to better protect the sample storage bottle during carrying, which is inconvenient to carry and use. By embedding it in the sampling place during use, the same Water at different depths at one location can be sampled simultaneously, and the sampling depth of the device can be adjusted by adjusting the overall length of the device according to actual conditions. It has high flexibility and is more convenient for subsequent testing. At the same time, after the sampling is completed, the liquid storage cylinder can be stored inside the outer frame, and the top plate and the sealing plate can simultaneously seal the upper and lower ends of the outer frame to achieve hidden protection for the liquid storage cylinder, which is more convenient to carry and use. However, the sampling interval height of the application interval is a fixed value, and it is difficult to flexibly adjust the sampling spacing, resulting in difficulty in adjusting the sampling level height and difficulty in increasing or decreasing the number of samples at a time. It is not flexible and convenient to use, and further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content
