AI Technical Summary

Technical Problem

The existing sampling tubes cannot be replaced or cleaned after sampling, resulting in water retention in different non-monitored watersheds and affecting the water quality monitoring effect.

Method used

A mobile water quality sampling device for irrigation water quality monitoring was designed, including a buoyancy mechanism, a sampler, and a sampling cylinder. The sampling mechanism, which uses a central wheel, a toothed block, and a gear meshing, enables the vertical movement of the partition plate and the flow of water. The inner wall of the sampling cylinder is cleaned by a fan blade and a circular scraper, ensuring the accuracy of water quality monitoring.

Benefits of technology

This allows for the circulation and cleaning of water within the sampling tube, avoiding any impact on water quality monitoring after sampling and ensuring the accuracy and reliability of water quality monitoring.

Abstract

The invention provides an irrigation water quality monitoring and flowing water quality sampling device, and relates to the technical field of water quality monitoring and sampling, the irrigation water quality monitoring and flowing water quality sampling device comprises a snorkeling mechanism, and a sampler is fixedly mounted on the snorkeling mechanism; a plurality of sampling barrels are fixedly mounted at the bottom in the sampler, and sampling mechanisms are arranged in the plurality of sampling barrels. Through rotation of the two fan blade scrapers, buoys (moss), weeds and the like on the outer surface of the sampling barrel can be scraped and cleaned, water flow on the peripheral side of the sampling barrel can be promoted to flow when the two fan blade scrapers rotate, the sampling barrel is prevented from being blocked, meanwhile, the round scrapers can clean the inner wall of the sampling barrel before the partition plate descends for sampling, and the sampling efficiency is improved. Water below the round scraper in the sampling barrel circulates around the sampling barrel, so that the water quality monitoring effect is prevented from being influenced by water staying at the bottom in the sampling barrel for a long time. The partition plate fixedly connected with the bottom of the sampling rod is driven to descend firstly and then ascend, so that the partition plate does vertical movement of descending firstly and then ascending, and water quality sampling of the sampling barrel is achieved.
