[0002] Water quality monitoring is a series of inspections and tests on various water sources used, such as river water, lake water, well water, etc., to understand their quality and pollution status. It usually involves collecting water samples and then using various scientific methods and instruments to analyze the chemical composition, microbial content and other factors that may affect water quality in these water samples.

After the side spring pops out the limit block B202 and squeezes the limit bracket A303 to completely slide into the inner side of the limit slot 2 for engagement, the position adjustment of one of the water quality monitors 5 is completed, and the other water quality monitors 5 that need to be adjusted are adjusted in the same way. Finally, the staff places the adjustment bracket 1 on the surface of the river, so that the buoy 101 drives the mounting frame 3 to float on the water surface as a whole, and then pushes the adjustment disk 106 to drive the damping telescopic rod A107 and the outer spring to expand, and drives the limit block A108 to slide out of the limit slot A109 to release the gear 105, and then pushes the adjustment disk 106 to drive the gear 105 and a plurality of teeth 104 to engage in transmission, and drives the adjustment rod 103 to slide downward or upward on the inner side of the adjustment slot 102, so that multiple water quality monitors 5 After extending into the specified depth of the river, loosen the adjusting disk 106, so that the damping telescopic rod A107 and the outer spring contract the adjusting disk 106 to drive the limit block A108 to slide into the relative limit groove A109 to limit and fix the gear 105, the staff holds the tow rope 6, and extends the mounting frame 3 into the water, so that the monitoring head of the water quality monitor 5 contacts the water for water quality monitoring. After a period of time, take the adjusting rod 103 out of the river, and turn the limit card frame B402 to slide out of the limit groove C403 to loosen the sliding frame 401, and push the sliding frame 401 to slide on the inside of the slide groove B4, so that the damping telescopic rod C404 and the outer spring expand to loosen the limit clamp 405, loosen the water quality monitor 5 and take out the mounting frame 3 to complete the water quality monitoring process.
