Problems solved by technology

The traditional way of testing after collecting water samples is difficult to accurately reflect the real-time water quality conditions in the field due to possible changes in the water samples during the process of collection, transportation and storage. Therefore, it is gradually being replaced by on-site in-situ measurement methods.
However, the device for in-situ measurement in the target sea area will drift due to the influence of sea wind and waves, and is easily damaged by environmental factors, with a short service life and can only meet the needs of short-term tasks
In addition, sensors used for water quality detection may become invalid due to the attachment of organisms and sediments when they stay in the water for a long time

Abstract

The invention provides a device for monitoring marine water quality. The device comprises a floating box and a probe, wherein the periphery of the floating box is provided with a jet port for controlling the geographical position of the floating box through air injection; the probe is provided with a sensor used for monitoring the water quality and a balloon used for controlling the depth of the probe in water. The invention also provides a method for monitoring the marine water quality by using the device. The device is compact in structure, solid and high in reliability, can be convenientlymoved to or maintained at a set position and water depth to detect the water quality, can conveniently clean the sensor to prolong the service life of the sensor, and thus is particularly suitable formarine deployment and long-term work.

Description

technical field [0001] The invention relates to the technical field of ocean water quality monitoring, in particular to a device and method for monitoring ocean water quality. Background technique [0002] Monitoring technology is the foundation of marine scientific research activities. Ocean water quality parameters, such as temperature, salinity, chlorophyll, turbidity, dissolved oxygen, pH value, etc., are important contents of monitoring. The traditional way of testing after collecting water samples is difficult to reflect the real-time and accurate water quality conditions in the field due to the possible changes in the water samples during the collection, transportation and storage process. Therefore, it is gradually being replaced by the in-situ measurement method. However, the in-situ measurement devices will drift in the target sea area due to wind and waves, and are easily damaged by environmental factors, with a short service life and can only meet the needs of s...
