Water Quality Monitoring Buoy: Empowering Pollution Control with Instant Data

The Water Quality Monitoring Buoy is an unattended field device that integrates multiple water quality monitoring sensors onto a buoy, which is deployed in water bodies requiring monitoring. It enables real-time online water quality monitoring. By leveraging technologies such as on-site sensor monitoring, solar-powered autonomous energy supply, modern wireless communication, data acquisition, and cloud platform monitoring, combined with mature field operation and maintenance experience, it stands as an advanced and modern water body monitoring tool.

Such monitoring stations are fixed in water via anchor chains, allowing for direct in-situ water quality measurement. They conduct 24/7 continuous, fixed-point tracking of water quality changes and can transmit monitoring data to the central station in real time. With these capabilities, staff can quickly grasp the current water quality status and variation patterns at the monitoring section, detect environmental pollution issues promptly, and provide robust data support for river basin water quality assessment, pollution prevention and control decision-making, and comprehensive remediation efforts.

Key components include the buoyant body, power supply unit, data acquisition and transmission unit, mooring unit, analysis unit, and auxiliary unit. The analysis unit adopts physical monitoring methods and can be equipped with various electrochemical or optical detection instruments for parameters such as water temperature, pH value, dissolved oxygen, turbidity, conductivity, chlorophyll-a, cyanobacteria, ammonia, and COD. The data acquisition and transmission unit features multiple digital and analog interfaces, enabling simultaneous connection to multiple digital water quality devices. It also has a large memory capacity, ensuring that stored data is not lost even in the event of a power outage. The auxiliary unit is an optional configuration, including equipment such as alarm lights and GPS positioning.

It enables in-situ monitoring, eliminating the need for pipeline transportation of the water sample to be tested, so measurements are not interfered with by intermediate links. The buoyant body is lightweight yet highly buoyant, with excellent wave-following performance. It also boasts a simple structure, high stability, and strong load-bearing capacity, facilitating deployment, retrieval, position adjustment, and movement. Additionally, the buoyant body is equipped with anti-collision self-protection functionality: it will not damage contacting objects such as ships upon collision, and even if it itself is damaged, it will not take on water and sink, thus effectively protecting the internal measurement instruments. Constructed from high-molecular polyethylene material and filled with foam inside, the buoyant body exhibits strong corrosion resistance, prevents the attachment and growth of aquatic organisms, and has excellent impact resistance. Furthermore, it has a low center of gravity, offering superior wind and wave resistance. No additional paint application is required, ensuring no pollution to the surrounding environment.
