A marine hydrological observation device

Abstract

The present application relates to a kind of marine hydrographic observation devices, it includes four observation instruments (31) and floating box body (1), the top of floating box body (1) is fixedly connected with four fixed long crosspieces (2), observation instrument (31) is above the end of fixed long crosspiece (2), setting four observation instruments (31) realizes 360 ° no dead angle monitoring;Observation instrument (31) is equipped with fine adjustment rotating cylinder (20) and floating cylinder (23) between fixed long crosspiece (2), when working, by increasing or reducing the internal water volume of fine adjustment rotating cylinder (20), floating cylinder (23) makes its internal pressure increase or decrease, drives observation instrument (31) small range forward rotation or reverse rotation, and the angle of observation instrument (31) is adjusted more comprehensively;The internal pressure of fine adjustment rotating cylinder (20) and floating cylinder (23) increases or decreases, to maintain the draught of floating box body (1), the whole device keeps the draught unchanged, does not affect the precision of observation instrument adjustment.
