Online monitoring device of longitudinal section fixing type multi-parameter water quality

Abstract

The invention discloses an online monitoring device of a longitudinal section fixing type multi-parameter water quality, comprising a shore base station, a water bottom monitoring platform and an anchor mooring line loaded water quality monitoring device; the shore base station is built in a water source shoreside station room with stable power supply and good ventilation and radiation, and comprises a supply source and a monitoring center; the water bottom monitoring platform is in communication with the shore base station through a photoelectricity composite cable, thus the sustainable energy supply and signal collection of the underwater monitoring device and the water quality monitoring device are realized; the anchor mooring line loaded water quality monitoring device is fixed at the fixed depth in the water through an underwater anchor, and connected to the water bottom monitoring platform through a watertight cable with a fixed length, thus the sustainable power supply is completed, and the water quality monitoring device can stably run for a long term. The online monitoring device has the advantages of long-term, continuous, in-situ online monitoring of section water quality at underwater, and breaks through the disadvantage of locating at the water face or sampling in traditional method.

Description

technical field [0001] The invention relates to a fixed multi-parameter water quality online monitoring device with a longitudinal section, which is applied to the online monitoring of water quality in rivers, lakes, reservoirs, oceans and other water environment, and provides vertical, three-dimensional, in-situ fixed real-time online monitoring for the water environment . Background technique [0002] At present, water quality monitoring methods are mainly divided into three methods: manual sampling monitoring, buoy monitoring and automatic monitoring station online monitoring. Manual sampling monitoring is to manually collect and transport water samples from water sources to the laboratory for laboratory testing, which is inefficient, and the water samples are not representative after a period of storage; buoy monitoring is mainly to fix the water quality monitoring equipment under the floating body. Hang it at a depth of 0.5 meters underwater to monitor surface water qu...

Problems solved by technology

[0003] Purpose of the invention: The purpose of the present invention is to provide a method for longitudinal, cross-sectional, in-situ and fixed-depth monitoring of water sources for the problems of low efficiency, narrow monitoring area, and inability to truly and comprehensively reflect the water quality in current water quality monitoring methods. The device can run continuously for a long time at a preset specific location to ensure a more realistic and comprehensive monitoring of water quality in fixed locations
