The invention discloses a cold-proof device suitable for a surface seawater sampling system, which comprises a shell, the inlet end of the shell is connected with one end of a first seawater connecting pipe, the outlet end of the shell is connected with one end of a second seawater connecting pipe, an ice filter screen is arranged in the shell, and the ice filter screen is arranged around the inner cavity of the shell to form a cylindrical shape; the ice filtering net is arranged between the first seawater connecting pipe and the second seawater connecting pipe, a disturbance structure used for disturbing seawater is arranged in a cylinder formed by the ice filtering net, the shell is connected and communicated with one end of the ice discharging pipe, and the connecting position is located at the top of the exterior of the shell or close to the top; and openings are respectively formed in the ice filtering net at the positions of the ice discharging pipe and the first seawater connecting pipe. According to the invention, a physical disturbance mode is adopted to destroy the blocking condition of ice crystals and ice floccules so as to prevent the ice crystals and the ice floccules from forming a complete and continuous ice film. In the ice region environment, the method adopts a seawater disturbance mode, so that the data authenticity of the sample can be protected, and the sampling continuity of the surface seawater cannot be influenced.
本发明公开了一种适用于表层海水采样系统的防寒装置,包括壳体,壳体进口端连接第一海水接管一端,壳体出口端连接第二海水接管一端,壳体内设有滤冰网,滤冰网环绕壳体内部腔体一周布置,形成圆筒状,滤冰网设于第一海水接管和第二海水接管之间,滤冰网形成的圆筒内设有用于扰动海水的扰动结构,壳体与排冰管一端连接并接通,且连接处位于壳体外部的顶部或靠近顶部位置;滤冰网上位于排冰管和第一海水接管位置分别设有一个开口。本发明通过用物理扰动的方式,破坏冰晶和冰絮板结成块的条件,阻止其形成完整连续的冰膜。在冰区环境下,本发明由于采用的是扰动海水的方式,所以不仅可以保护样本的数据真实性,还不会影响表层海水采样的连续性。
