The seawater turbidity on-site monitoring sensor is put underwater through a cable, and can measure the turbidity under the control of a micromotor program, so that the long-term on-line measurement at a fixed point on the sea can be realized.
Description
Technical field
The utility model relates to ocean measuring instrument, particularly relates to a kind of optical instrument of measuring the seawater turbidity.
Background technology
The turbidity of seawater is the important parameter of marine environmental monitoring.Exist silt, suspension etc. in the seawater, make seawater present muddy opaque state, turbidimetry is exactly a muddy degree of measuring seawater.
At present, the spot sampling measuring method is mainly adopted in the monitoring of turbidity of sea water, design, determine the turbidity of sea water value by measuring seawater sample light scattering situation according to international ISO 7027 turbidimetry standards.When a branch of incident light injects in the seawater, because the existence of water suspension causes to occur the optical scattering phenomenon in the seawater, determine turbidity value, the principle of Here it is turbidimetry according to seawater scattered intensity size.Traditional sampled measurements analytical approach exists that the institute sample thief is representative poor, sample takes place easily to precipitate and optical lens is vulnerable to many drawbacks that biological attachment and pollution etc. influence measurement result in gatherer process.
Therefore, existing turbidity of sea water survey sensor can not be realized marine on-the-spot long-term fixed point on-line measurement.
Summary of the invention
Problem at existing turbidity of sea water survey sensor existence, the utility model has been released the novel turbidity transducer that is used for the seawater in-site measurement, its objective is the brusher that drives by motor internal in the external installation of sensor shell, remove biological attachment and pollutant on the sensor optics camera lens, solve the on-the-spot long-term on-line measurement problem of turbidity of sea water.
The related Turbidity Sensor on In-situ Oceanic Observation shell of the utility model is cylindrical, optical measuring system and cleaning systems are installed in the cylindrical shell, and the control circuit of optical measuring system and cleaning systems is connected with the micro computer of device waterborne with stube cable by the underwater electrical connector that the cylindrical shell rear end is provided with.
Optical measuring system comprises optical transmitting set (LED), photelectric receiver, lens, optical filter and window glass.Window glass is installed in sensor seal casinghousing front end, forms two transparent windows.The window glass of the corresponding transparent window of optical transmitting set, the window glass of corresponding another transparent window of photelectric receiver.Lens, optical filter place between its corresponding window glass of photelectric receiver.
Cleaning systems comprise motor, motor shaft, brusher, photoelectrical coupler, indicator stem.Photoelectrical coupler, motor connect with control circuit respectively.One end of motor shaft passes from the seal casinghousing of sensor front end, fixedlys connected with brusher.Brusher places the seal casinghousing outside of sensor front end, rotate under driving with motor motor rotating axle, and brush is installed in two window glass of sensor seal casinghousing front end.Indicator stem is fixed on the motor shaft, and indicator stem and brusher rotate under motor shaft drives synchronously.
Turbidity Sensor on In-situ Oceanic Observation is put in the water by cable, carries out turbidimetry by the micromotor programmed control.
When instrument was started working, motor drove brusher earlier and rotates two circles, with clean window stain on glass, prepared for beginning to measure.Brusher is being parked under the control of program on the position of shielding window glass not then.The position that brusher stops locating is determined by the interconnected of indicator stem and photoelectrical coupler.After brusher was finished clean window stain on glass, the programmed control optical transmitting set sent pulsed light immediately, and light enters in the seawater by the optical transmitting set window glass.Because the existence of suspension in the seawater produces scattered light, a part of scattered light passes lens and optical filter through the window glass of photelectric receiver, arrives photelectric receiver.Photelectric receiver converts light signal to magnitude of voltage output, and this magnitude of voltage has reflected the scattered light intensity of suspension, analyzes the turbidity that draws seawater thus.Simultaneously, use standard solution that output signal is calibrated, draw calibration curve, draw measurement result.
The utility model has been realized the on-site on-line measurement of turbidity of sea water, can use separately, also can be used on the integral instrument of seawater quality measurement aspect.
