Description

TECHNICAL FIELD

[0001] The utility model relates to water quality detection technical field, concretely is a compact folding mechanism for saving space. BACKGROUND

[0002] Water quality detection is an important means of water resource protection and pollution control, which involves using various equipment and technology to analyze the content of chemical substances, microorganisms and other pollutants in water. These devices can quickly provide water quality data on site, and they are usually designed to be easy to carry and simple to operate for on-site workers. Water quality detection may include multiple indicators such as TDS (total dissolved solids), pH value, hardness, microbial content, etc.

[0003] Chinese patent (authorized announcement number: CN215004464U, authorized announcement date: 2021.12.03) proposes a water quality detection collection mechanism, which puts the collection pipe and the water inlet pipe into the water area downward, and makes the vertical foot A and the vertical foot B of the collection pipe inserted into the soil surface outside the river channel. At this time, hold the rotating disc and rotate the I-shaped shaft. Under the action of the rotating force of the rotating I-shaped shaft, the rotating shaft drives the spiral auger to stir the water body entering the water inlet pipe upward. Under the spiral force of the spiral auger, the water body carries the top end of the collection pipe outward from the water outlet pipe. This kind of manual water quality collection mechanism can be moved conveniently without power.

[0004] The existing water quality detection collection mechanism is large and heavy in actual use, not easy to carry, and can only repeatedly collect water sources of different depths, cannot collect water sources of different depths at one time, wastes unnecessary time, and since the same collector is used to collect water sources of different depths, the precision may be affected.
