本实用新型涉及海洋测量仪器装置，特别是涉及深海测量海水温度和盐度（电导率）随深度变化的仪器装置。The utility model relates to a marine surveying instrument device, in particular to an instrument device for measuring seawater temperature and salinity (electrical conductivity) in deep sea as they vary with depth.
背景技术Background technique
海水的温度和盐度（电导率）是最基本的海洋水文参数。监测海中不同深度（D）的海水温度（T）和盐度（电导率C）的状况，具有广泛的科研和应用价值。海水温度和盐度的深度变化资料在减灾预报上可以作为海洋环境数值预报和灾害性海况遥测的基本数据资料，在军事上可以用于声纳作用距离预报和舰艇航海保障的海洋环境基本实测数据，在海水养殖中可以用于预报海水环境变化规律和控制生物最佳养殖环境等。The temperature and salinity (conductivity) of seawater are the most basic ocean hydrological parameters. Monitoring the seawater temperature (T) and salinity (conductivity C) at different depths (D) in the sea has extensive scientific research and application value. The depth change data of seawater temperature and salinity can be used as basic data for marine environment numerical forecasting and disastrous sea state telemetry in disaster reduction forecasting, and can be used for sonar action distance forecasting and basic actual measurement data of marine environment for naval navigation support in military affairs , in mariculture, it can be used to predict the changing law of seawater environment and control the optimal aquaculture environment of organisms.
目前，海水温度和盐度的剖面测量以船载投放式CTD（Conductivity Temperature Depth）剖面测量仪为主，在预定站位，由调查船的钢缆绞车将仪器吊放在海水中，并以均匀稳定的速度下放，利用温度（T）、电导率（C）、压力（D）传感器，完成不同深度点的温度和盐度（电导率）的测量。测量仪器大多采用自容式方式，测量数据存储在水下的存储器内，待测量仪器回收到测量船甲板上后，再将数据回放到计算机中，以显示和存储测量到的海水剖面温盐数据。At present, the profile measurement of seawater temperature and salinity is mainly based on the ship-borne CTD (Conductivity Temperature Depth) profile measuring instrument. Lowering at a stable speed, using temperature (T), conductivity (C), pressure (D) sensors to complete the measurement of temperature and salinity (conductivity) at different depth points. Most of the measuring instruments are self-contained, and the measurement data is stored in the underwater memory. After the measuring instruments are recovered on the deck of the survey ship, the data is played back into the computer to display and store the measured seawater profile temperature and salinity data. .
温盐测量传感器链也用于进行海下温盐数据测量。温盐测量传感器链是垂直吊放于浮标下的链状测量装置，由一根拉力主电缆悬挂多组CTD传感器构成，可以在海中长时间工作，实现对海洋垂直剖面上不同深度多层温盐的长时间同步监测，测量数据可以由浮标系统通过卫星传输到地面站。The temperature and salinity measurement sensor chain is also used for sea temperature and salinity data measurement. The temperature and salinity measurement sensor chain is a chain-like measurement device vertically suspended under the buoy. It is composed of multiple groups of CTD sensors suspended by a tension main cable. Long-term synchronous monitoring, the measurement data can be transmitted by the buoy system to the ground station through the satellite.
但是，上述自容式CTD剖面仪和温盐测量传感器链用于深海测量都存在一定的问题。所述深海测量是指6000米及其以深海域水下海洋要素的测量，从海表面到6000米及其以深海洋剖面温度盐度的变化规律，对于海洋剖面大深度科学研究非常重要。However, there are certain problems in the above-mentioned self-contained CTD profiler and temperature-salinity measurement sensor chain used for deep-sea measurement. The deep-sea measurement refers to the measurement of underwater marine elements in the deep sea area of 6000 meters and below. The change law of temperature and salinity in the deep ocean profile from the sea surface to 6000 meters and below is very important for the scientific research of the large depth of the ocean profile.
温盐测量传感器链有长达数百米的拉力电缆及其悬挂的多组CTD传感器构成，存在运输、安全、测试、维修的诸多不便，而且海上布放作业也比较麻烦。同时，由于吊挂电缆及布放的限制，温盐测量传感器链多用于海表面至500米水深，深海测量存在着不可逾越的困难。The temperature and salinity measurement sensor chain is composed of hundreds of meters of tension cables and multiple groups of CTD sensors suspended therein, which has many inconveniences in transportation, safety, testing, and maintenance, and the offshore deployment operation is also more troublesome. At the same time, due to the limitation of hanging cables and layout, temperature and salinity measurement sensor chains are mostly used from the sea surface to the water depth of 500 meters, and there are insurmountable difficulties in deep sea measurement.
自容式CTD剖面仪的工作方式，要求仪器可靠性非常高，仪器在下放过程中无法知道是否工作正常，只有待仪器回收后回放数据才能知道，一旦在测量过程中出现故障或异常，则剖面测量就无数据。自容式CTD剖面仪的工作方式，不能及时阻止无效的测量，易造成船时、人力的浪费。The working method of the self-contained CTD profiler requires the reliability of the instrument to be very high. It is impossible to know whether the instrument is working normally during the process of lowering the instrument. Only after the instrument is recovered and the data is played back can it be known. Once a fault or abnormality occurs during the measurement process, the profile Measurements have no data. The working method of the self-contained CTD profiler cannot prevent invalid measurements in time, which will easily cause waste of ship time and manpower.
