Deep sea water parameter measuring device

Abstract

The invention relates to a deep sea water parameter measuring device, and the prior device has low displacement efficiency and poor effect. The invention comprises a cabin and a sealing cover which are fixedly connected through bolts, wherein the central position of the upper end surface of the cabin is provided with a groove to form a sensor cavity; the bottom surface of the sensor cavity is an isosceles triangle surface which is parallel to the cabin end surface; the cabin is provided with two sensor installation holes; the two needle-type pH sensors are respectively arranged in the two sensor installation holes; two apopores are symmetrically arranged on the two outer side walls of the cabin to which the two base angles of the isosceles triangle directs; an inlet opening is arranged onthe outer side wall of the cabin to which the vertex angle of the isosceles triangle directs; and one inlet opening and two apopores are respectively provided with an electromagnetic valve on the opening of the outer side wall of the cabin. In the invention, the cavity shape of the sensor cavity, the quantity and distribution of the through holes are improved, thus being capable of greatly improving displacement efficiency, improving the trueness of the buffer solution or the sea water samples in the cavity after the completion of the displacement process, and being suitable for the sea watersamples of various densities.

Description

technical field [0001] The invention belongs to the technical field of deep-sea equipment and engineering equipment, and relates to a deep-sea seawater parameter measurement device. Background technique [0002] The deep-sea detector obtains the real dynamic data of seawater chemical quantity changes through long-term and continuous sampling and analysis of seawater samples, and initially detects seabed mineral deposits from the abnormal situation of seawater chemical composition. It has the advantages of light weight, simple operation and high sensitivity. At present, the sensors equipped on deep-sea detectors mainly use various electrochemical detection electrodes, and the measurement items are mainly H 2 S, H 2 , pH. my country has used Ir / IrO 2 The detection electrode is paired with the improved Ag / Agcl reference electrode, and the probe-type structure all-solid-state pH detection electrode is preliminarily developed, which is suitable for online detection of pH value...

AI Technical Summary

Problems solved by technology

The structure is simple and intuitive, easy to process and seal, but because the water inlet pipe and the water outlet pipe are designed in the center of the cylindrical cavity, there is a flow dead zone around it, which greatly reduces the gap between the buffer solution and seawater during the self-calibration process. At the same time, the actual degree of buffer and seawater samples decreased after the displacement process was completed.
