海洋站温盐传感器安装方式的研究

Study on the Installation Method of Thermohaline Sensors for Ocean Stations

表层海水温度及表层海水盐度是海洋水文观测中的重要测量参数。海洋站温盐传感器的安装方式,决定了表层海水温度及表层海水盐度数据测量的准确性、连续性及温盐传感器使用的寿命。文中提出了几种温盐传感器安装方式,比较了其优缺点,海洋站可以根据现场实际情况进行选择。其中"滑轮式"安装方式具有安装简单、可靠性高、维护方便等优点。为防止温盐浮子转动而造成电缆缠绕,提出了加装阻流板的解决方法。使用加装阻流板的"滑轮式"安装方式,浮子转动小,电缆缠绕几率低,简单可靠,可在海洋站推广使用。

Sea surface temperature and salinity are important measured parameters in oceanographic hydrological observation. The installation way of thermohaline sensors in ocean stations significantly affects the accuracy and continuity of measuring surface seawater temperature and salinity, as well as the service life of thermohaline sensors. This paper proposes 6 installation methods for thermohaline sensors and compares their advantages and disadvantages. Ocean stations can adopt appropriate methods according to practical situation in marine environmental monitoring. Among these methods, the ＂pulley＂ installation mode is featured by a number of merits, like simple installation, high reliability and easy access to maintenance. In order to prevent cable winding caused by the rotation of the thermohaline sensor float, the installation of a spoiler is suggested as a solution. The ＂pulley＂ installation mode combined with spoiler results in small float turning and low probability of cable winding. This mode, both simple and reliable, is suitable for wide applications in ocean stations.
