Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and in particular to a reagent-free multi-parameter online water quality monitoring device. Background Technology

[0002] With rapid economic and urban development, the urban population has increased dramatically, leading to a surge in domestic water consumption. Meanwhile, water pollution remains a significant problem, and the water supply security situation is far from optimistic. Online water quality monitoring utilizes online water quality analysis instruments as its core, employing modern sensor technology, automatic measurement technology, and computer technology to form a comprehensive automatic monitoring system that enables rapid water sample collection and analysis of water quality parameters.

[0003] While existing online monitoring systems can achieve continuous monitoring of some parameters, they still have many shortcomings. On the one hand, most systems can only monitor a single water quality parameter, and their monitoring functions are incomplete, making it difficult to meet the needs of simultaneous monitoring of multiple indicators in complex aquatic environments. On the other hand, existing online monitoring equipment has a complex structure, is inconvenient to install and maintain, and has stringent requirements for the installation environment, which limits its application scope. In addition, many online monitoring systems require frequent addition of chemical reagents during the monitoring process, which not only increases operating costs but may also lead to secondary pollution. Moreover, the use of chemical reagents is contrary to the current trend of environmental protection and sustainable development. Utility Model Content

[0011] This invention provides a reagent-free, multi-parameter online water quality monitoring device, which has the following advantages:

[0012] In use, this invention utilizes a water pump to deliver the required monitoring water flow to a storage tank. A turbidity sensor simultaneously monitors multiple key parameters online, including temperature, pH, salinity conductivity, dissolved oxygen, COD, ammonia nitrogen, and turbidity. Based on electrochemical reaction principles, it can quickly and accurately detect changes in water ion concentration and related physicochemical parameters, converting the detection signals into electrical signals in real time. The turbidity sensor probe employs a reagent-free design, avoiding the use of chemical reagents in traditional monitoring systems. This reduces reagent costs and eliminates the environmental pollution risks associated with waste reagents, aligning with the development direction of green monitoring. By connecting a cleaning pipeline, the turbidity sensor achieves intermittent automatic sewage discharge and automatic probe cleaning, effectively reducing dirt adhesion on the probe surface, ensuring the accuracy and stability of monitoring data, and lowering the frequency and workload of manual maintenance. This allows for long-term unattended operation.

[0013] In addition, when the equipment needs to be moved, the bottom of the equipment is supported by rollers, making short-distance movement of the equipment easier; when the equipment is moved to the required position, the double-headed screw is rotated, which drives the movable block to move outward.
