Description
The invention belongs to a kind of instrument of measuring water turbidities such as tap water, process water and rivers and lakes water, be specially adapted to high turbidity water quality or turbidity variation water quality greatly and carry out continuous monitoring.Simultaneously, the present invention also can be used for hydrology department monitoring silt charge in river water content under the situation that changes formula.
Domestic and international existing turbidimeter, it is measured in the light path system partly and all adopts constant light source, promptly use a specified standard light source, this can only be used for the measurement of water quality in certain turbidity scope, and can not be with the bigger variation of water turbidity conversion measurement range thereupon.In addition, the light source convex lens in light path system, when lens or photoelectric cell superficial dust, constant standard sources can not adapt.
Existing turbidimeter uses reflective measurement structure on light path principle both at home and abroad, be that the light that light source sends is measured through the reflection of the tested water surface, along with the rising of tested water turbidity, measuring system just can enter saturated very soon and can not adapt to the measurement requirement that turbidity raises.
Have turbidimeter now and be integral structure on forming, i.e. measurement part and computing machine partly connect together and become an integral body, thereby the installation and maintenance difficulty, the high and selection installation environment of erected cost.Simultaneously, integral structure is owing to needing longer conduit pipe, so the data of surveying easily are offset worn-out ends such as actual value.
Domestic existing turbidimeter does not have the microcomputer product, though the turbidimeter of microcomputer product is abroad arranged, existing both at home and abroad turbidimeter all can not carry out the wide range turbidity value and measure.
Because the destruction of ecologic environment, the rivers sediment charge constantly increases, and particularly the high water systems of water turbidity such as China the Yellow River, the Changjiang river and Jia Lingjiang River fail to solve ultra's problems of measurement for many years always.
How to solve turbidimeter and in long-term the use, need not manually adjust or demarcate light source, and make it change automatic transformation light source accurately to measure with water turbidity, particularly to the measurement of still indeterminable high turbidity value water quality both at home and abroad at present, make it be easy to installation and maintenance, easy and simple to handle, energy-conservation and measuring accuracy height is the purpose that the present invention will reach
Through China Science Technology intelligence Institute ChongQing Branch's hand inspection and international online retrieval, adopt structural principle of the present invention, can reach the turbidimeter that 40000 mg/litre high turbidity water qualities are measured, still there is not this precedent (the search report book of seeing Appendix) at present both at home and abroad.
The present invention is by measuring partly and computing machine is partly formed two style structure promptly to measure part be one (comprising water circuit system and light path system), and computer system is another body.Measure partial structure shown in accompanying drawing (1), its water circuit system has: dirty sheet (5) wiped by operating motor (1), suction water vat 2 pull bars (3), light path frame (4), ox-hide and rectangle water jacket (6) is formed.Its light path system has: light source (7), convex lens (8), lens (9), optical attenuation plate (10), photoelectric cell (11) and electric contact thermometer (12) are formed.
Computing machine partly as accompanying drawing (2) block diagram shown in, comprising: Z80 single card microcomputer, 16 row (band single-chip microcomputer) mini-printers, 14 A/D, 12 D/A(current modes of two-way), execution switching value interface and 1 " composition such as nixie display.
Measure partly this body and adopt floating drum installations of bubbling through the water column, also can be install suction pipe additional bottom it, directly draw tested water without floating drum.Computing machine partly this body then is placed in the pulpit, connects with signal cable between two bodies.Connect with the mains, press computer power switch, this turbidimeter can enter duty.
Principle of work is as follows: during the water circuit system suction, operating motor 1 turns clockwise, upstroke in the suction water vat (2), pull bar (3), light path frame (4) and ox-hide are wiped all risings simultaneously of dirty sheet (5) at this moment, tested water is sucked in the rectangle water jacket (6), partly carry out turbidimetry for light path system and computing machine.During the water circuit system draining, the rotation of operating motor (1) inhour, suction water vat (2) inner carrier is descending, this moment pull bar (3), light path frame (4) and ox-hide wipe dirty sheet (5) all the while descending, tested water is discharged rectangle water jacket (6) like this, ox-hide is wiped dirty sheet (5) and just the lens in the light path system (9) is wiped dirt once, and the center of light path frame (4) just in time is parked on the center line of lens (9), and the path of a light is provided for the automatic adjusting light source.
The measurement water layer thickness that rectangle water jacket (6) in the water circuit system is controlled is 30 ± 0.10mm, and inner plane requires smooth bright and clean.
The electric contact thermometer of light path system (12) is the control circuit heating element, make photoelectric cell (11) constant temperature in the working temperature of 45C to improve the stability of photoelectric cell (11).
The power of light source is done dynamically control by the 0-10mA current signal of computing machine and output, and it is divided into two kinds of duties:
The demarcation of A turbidity light source when 5000 mg/litre are following.
When light path frame (4) fell and overlaps with the center of lens (9), computing machine was adjusted light source by detecting the current value of photoelectric cell (11), makes light source (11) adjust to standard value automatically.
The demarcation and the measurement of B turbidity light source when 5000 mg/litre are above.
When light source can not satisfy that water turbidity raises and when surpassing 5000 milliliters/liter measurement, this moment, light source must strengthen, and after the light source of the demarcating enhancing, if no high turbidity water quality's blocks, light source after the enhancing can burn photoelectric cell (11), when demarcating light source, computing machine sends instruction and earlier optical attenuation plate (10) is moved on to photoelectric cell (11) front end, begins to demarcate light source then for this reason.During measurement, earlier tested water is sucked rectangle water jacket (6), optical attenuation plate (10) is removed just entered turbidimetry then.All measuring processes all are to be handled by computing machine, and it is exported as calculated and draws after the machine linearization process, and so good linearity, error is little, and can be directly and Other Instruments and the supporting use of computing machine carry out continuous monitoring and print record or automatic control.
The computing machine partly course of work is seen accompanying drawing (3) block diagram.
From accompanying drawing (3) block diagram, can find out that the adjustment of light source and the measurement of turbidity value all are dynamically to realize overall process.Block diagram was measured by 15 minutes and is once worked out in the accompanying drawing (3), also can program by different Measuring Time as requested.
The present invention structurally adopts double-body bike to compare with the integral type of prior art, install simple, overcritical installation environment, erected cost is low, need not install water-transmission line additional, complete machine is water consumption type not fully, than conventional turbidimeter year economizing on water more than 3000 cubic metres.Simultaneous computer is loaded on the indoor Operation and Maintenance of being convenient to.
This is the another significant feature that is different from the constant light source that domestic and international prior art adopts to adopt full-automatic dynamic light source in light path system.Existing turbidimeter all is to use the specified standard light source, and demarcation light source of the present invention is the dynamic light source that thereupon changes with the variation of environmental working condition.When the survey water turbidity bigger variation takes place or at convex lens (8), lens (9), photoelectric cell (11) superficial dust during to the constant light source incompatibility of standard, dynamic light source is with automatic conversion calibration value, accurately measuring, thereby need not in using all the year round, light path system and water circuit system are artificially being cleaned and cleaning.Simultaneously, complete machine of the present invention is realized the gamut automatic measurement, and can realize the measurement of the insurmountable high turbidity value of prior art is also mainly realized by the dynamic light source principle.
Light path system of the present invention has adopted Nonopaque type measurement structure (be light that light source sends pass tested water layer detect to photoelectric cell (11)) to compare with the reflective measurement structure that prior art is adopted, improve the degree of accuracy of measuring greatly, also improved the measurement range of turbidity value simultaneously greatly.
The present invention has adopted rectangle water jacket (6) to replace the design of garden shape water jacket in the prior art in water circuit system, and this also helps the raising of measuring accuracy to have thickeied the measurement water layer simultaneously.
Range ability of the present invention is wide, can carry out full-automatic range and measure in turbidity 0-40000 mg/litre scope.It is CD-1 type (0-40000PPM) turbidimeter that the present invention can not be with mini-printer, and also can be with 16 row mini-printers is CD-1A type (0-40000PPM) turbidimeter.The present invention also can connect with other microcomputer and register instrument, and there is 0-10mA output signal (linearization) the cabinet back and takes advantage of 10 switching value signals output, and when taking advantage of 10 signals to be high level, electric current is on duty 10, direct-reading current value during for low level.The present invention considers the cost problem, so with 12 D/A outputs, add and take advantage of 10 signals, also can adopt 16D/A to remove and take advantage of 10 signals, and gamut just can directly have been read the 0-10mA value.
