When in labor hours, sea water sample is injected from the intake into the colorimetric flow cell at a constant flow rate, and after the colorimetric flow cell is full, the excess water sample flow into the liquid storing cup. The light transmitter transmits light under the control of program, and the light wave is sent through water sample in the colorimetric flow cell to the photoelectronic receiver which then transforms light signals into magnitudes of voltage to export, wherein the magnitudes of voltage reflect the light absorption intensity of sea water sample, thereby obtaining the nutrient salt content of sea water sample.

Description
Technical field
The utility model relates to ocean measuring instrument, specifically is a kind of optical instrument of Measuring Oceanic tincture.
Background technology
Nutrients in sea water is the important parameter of marine eco-environment monitoring, and the eutrophication of seawater and appropriate nutrition salt structure are one of principal elements that causes red tide.
At present, the monitoring of nutrients in sea water is mainly still prolonged with the traditional spot sampling and the method for lab analysis.This traditional lab analysis measuring method exists that the institute sample thief is representative poor, sample vulnerable to pollution and sample nutritive salt in storage and transport can lose and many drawbacks such as variation in collection and pre-service.
The research of the on-the-spot automatic measurer of nutrients in sea water is also at the startup, and the method for employing is a micro chemical laboratory method.The ultimate principle of the method is an absorption photometry, according to seawater sample the optical transmission situation is determined the content of its nutritive salt therefore, in the seawater sample bubble can not be arranged, in order to avoid influence measurement accuracy.The on-the-spot automatic analyzer of existing a kind of nutrients in sea water adopts the photometric optical measuring device of pump suction type, has defectives such as being easy to generate bubble, chemical-resistant reagent corrosion difference.
Summary of the invention
At measuring the problem that the nutrients in sea water prior art exists, the utility model has been released the optical measurement flow cell that is used for the on-the-spot automatic analyzer of nutrients in sea water, its objective is the unitized construction that adopts colorimetric flow cell and optical transmitting set and the photelectric receiver of bringing the mouth of a river and water delivering orifice into, automatically measure the content of the seawater sample nutritive salt of containing in the colorimetric flow cell, to solve the on-the-spot problems of measurement automatically of nutrients in sea water.
The related optical measurement flow cell of the utility model is made up of optical transmitting set, photelectric receiver, colorimetric flow cell and liquid storing cup.The colorimetric flow cell is a tubular structure, and two ends are connected with photelectric receiver with optical transmitting set by the window glass of sealing respectively.Optical transmitting set is made up of semiconductor light sources, balsaming lens and window glass, semiconductor light sources is sent the monochromatic optical wave that a hot spot is big, the angle of divergence is bigger, this Shu Guangbo is integrated into the light wave of diameter less than 3mm through balsaming lens, through window glass, enters the colorimetric flow cell.Semiconductor light sources luminous by control circuit and software control.Photelectric receiver is placed on the other end of colorimetric flow cell, and is relative with optical transmitting set, and optical transmitting set, colorimetric flow cell and photelectric receiver are coaxial.
There is water delivering orifice colorimetric flow cell top, and there is water inlet the below, and water inlet and water delivering orifice are the thin conduit type, and water inlet, water delivering orifice and colorimetric flow cell light path become " Z " font, to reduce the delay of bubble in light path.Colorimetric flow cell housing is selected the black PVC material for use, reduces the scattering in the light wave propagation process, improves the corrosivity of chemical-resistant reagent.
Liquid storing cup is settled in the water delivering orifice upper end, and the liquid storing cup lower end communicates with water delivering orifice, and the upper end communicates with outside air, plays the effect of getting rid of air in the water sample.The water inlet lower end is installed into water swivel.
During instrument work, seawater sample injects the colorimetric flow cell with constant flow rate by water inlet, and after the colorimetric flow cell filled with water sample, unnecessary water sample flowed into liquid storing cup.Optical transmitting set issues out light beam in programmed control, light wave is by water sample in the colorimetric flow cell, pass to photelectric receiver, photelectric receiver is with light signal, convert magnitude of voltage output to, this photoelectricity voltage value has reflected the degree of absorption of seawater sample to light wave, analyzes the nutrient concentrations that draws seawater sample thus.Simultaneously,, the photoelectricity voltage signal is revised the measuring error of bringing with the instability of eliminating light source according to the stability of light source output signal.
The utility model has been realized the on-site rapid measurement of nutrients in sea water, also can be used for metric measurement sewater chemistry oxygen utilization, sulfide, prussiate etc.
