The present invention discloses an in situ detection system for low-temperature hot liquid area in deep sea, which comprises a hot liquid sampling and detecting device, a power supply device, a microcomputer control device and an electrode flushing and calibrating device. Wherein, a detecting electrode of the hot liquid sampling and detecting device can detect chemical compositions of the hot liquid while the hot liquid flows. A signal output terminal of the microcomputer control device is connected with an ICL coil to transmit signals to a submersible boat. The electrode flushing and calibrating device calibrates the detecting electrode in the hot liquid sampling and detecting device. The present invention relies on its batteries to realize power supply and automatically operates for long in deep sea. In addition, the present invention is provided with three operating states, such as low-temperature hot liquid detection, detecting electrode flushing and detecting electrode calibrating, which are switched by the microcomputer control device. Moreover, the present invention has functions of low-temperature hot liquid long-time detection and independent maintenance and calibration of the detecting electrode, thus greatly improving performance of the detecting electrode and accuracy of chemical quantity detecting and providing detailed and accurate data for scientific research on hot liquid in deep sea.
Description
technical field [0001] The invention relates to an in-situ detection system suitable for deep-sea low-temperature hydrothermal areas, specifically a system whose automatic operation is controlled by a microcomputer, and has the functions of long-term in-situ detection of hydrothermal fluids and self-maintenance and calibration of chemical electrodes. Background technique [0002] At present, in the exploration of marine resources, the international marine community has carried out research on the detection technology of deep-sea hydrothermal fluids. Among them, the detection of the chemical quantities of hydrothermal fluids contained in seawater in low-temperature ecological zones near hydrothermal vents is the key to understanding the relationship between these life forms and One of the keys to the ecosystem. Most of the traditional detection of low-temperature hydrothermal areas uses the method of sampling and analysis to observe the change of hydrothermal composition, whi...
