Description

Technical Field

[0001] This utility model relates to the field of online water quality monitoring technology, and in particular to an online water quality monitoring device that can be installed under pressure in a water supply network. Background Technology

[0002] Water supply networks are a crucial component of urban infrastructure, and the safety of their water quality directly impacts residents' health and the normal operation of the city. With accelerating urbanization and rising living standards, real-time monitoring and management of water quality in water supply networks have become increasingly important. Traditional water quality monitoring methods have many limitations, such as requiring regular manual sampling and testing, the inability to achieve real-time online monitoring, long testing cycles, and untimely data feedback, making it difficult to meet the demands of efficient management of modern urban water supply networks.

[0003] While some online water quality monitoring devices for water supply networks have emerged in the market, several problems remain. Some devices employ complex power supply methods, making stable operation difficult in remote areas or outdoor environments without mains power. Mechanical connections are inflexible, failing to meet the installation requirements of pipes of varying diameters, and the complex installation process makes pressurized installation difficult, affecting the normal water supply of the network. The protective casing is insufficient, making them susceptible to damage in complex outdoor environments. Sensor maintenance and replacement are difficult, resulting in high repair costs and time-consuming repairs, impacting the continuity of monitoring. Communication methods pose security risks, as data transmission is easily stolen or tampered with, hindering remote operation and increasing risks associated with confined space operations. The most significant problem is the flow-through installation, requiring some water samples to be discharged. For water supply pipelines, there is no space for external discharge, leading to water waste. Furthermore, water supply pipelines are underground, and water quality monitoring points are typically installed in wells, requiring personnel to descend into the wells for maintenance, which is unsafe. Therefore, developing an online water quality monitoring device for water supply networks that can be powered by DC power, has strong mechanical connection interface adaptability, good protection performance, easy sensor maintenance, can be operated and maintained under pressure, and has safe and fast communication is of great practical significance. Therefore, we propose an online water quality monitoring device for water supply networks that can be installed under pressure. Utility Model Content
