Buoy configuration: vertical profile monitoring buoy is mainly composed of buoy main structure, vertical lifting system, power supply unit, auxiliary equipment, etc. The main structure of the buoy, as the carrier of the whole buoy water quality online monitoring system, provides the necessary installation space and environmental basic platform for the instruments and equipment required for the normal operation of the whole system; The vertical lifting system provides technical support for the installation of water quality analysis instruments, including data acquisition, communication system and other control equipment; The power supply unit includes storage battery and solar panel, etc; Auxiliary equipment mainly includes anchor system, navigation lights, etc.

According to the actual situation, the configurable monitoring instruments mainly include a water quality multi parameter analyzer and related communication control equipment, which can realize the on-site real-time on-line monitoring of main water quality indicators (including water temperature, dissolved oxygen, conductivity, pH, turbidity, ammonia nitrogen, chlorophyll a, blue-green algae and other indicators) and Meteorology (temperature, humidity, wind speed, wind direction, rainfall and other indicators).

Buoy main structure: the buoy main structure is located in the middle of the buoy, which is mainly composed of the closed cabin cover and the cabin, so that the instrument room can be fully protected by the buoy itself, thus providing a sealed and waterproof space for the installation of the system host including data acquisition, communication unit, storage battery and other control equipment, The normal operation of the whole monitoring unit is ensured.

Vertical lifting system: the vertical lifting system is in direct contact with the water through the bottom stabilizer, which can balance the pressure of the buoy and keep it at an appropriate level. The connection between the vertical lifting system and the main warehouse is carried out through the watertight joint on the plate cover, and the flange installation method is adopted on the plate surface. The system is equipped with low-power vertical lifting motor to ensure long-term stable operation.
