Shortcoming have that power consumption is high, caloric value is big, light source maintenance is big.
The content of the invention
The technical problem to be solved in the present invention, is to provide a kind of online turbidity meter of lower range low-power consumption.
What the present invention was realized in：A kind of online turbidity meter of lower range low-power consumption, including upper shell, lower casing
Body, signal processing module, snoot, LED, collimation lens and detector；There is a measuring cell, the letter in the lower house
Number processing module is located at the top of upper shell；The snoot is fixedly connected in upper shell, steady provided with one inside the snoot
Flow module, the current stabilization module is connected with signal processing module；The LED is embedded in snoot, and with the current stabilization mould
Block is connected；The collimation lens is correspondingly arranged at the underface of snoot, and positioned at the top of measuring cell；The bottom of the detector
Insert in measuring cell, upper shell is anchored at the top of the detector, and the detector is connected with signal processing module.
Preferably, in addition to a support；The snoot includes a connecting portion and a cover body, and the top surface of the cover body is downward
Depression forms ground recess, and the center of the recess is provided with an open-work, and the current stabilization module is placed in the recess, and the LED is embedding
Enter open-work；The connecting portion and cover body are detachably connected, and the outer wall of the connecting portion is equipped with a groove；One end of the support
In the embedded groove, the other end is fixed on upper shell.
Preferably, the snoot is stainless steel.
The advantage of the invention is that：
1st, power consumption is greatly reduced, 78.4% is have dropped；
2nd, snoot plays preliminary optically focused effect, and the heat distributed can be heated to collimation lens, be atomized collimation lens
Probability reduction, atomization can influence the intensity of light.
Brief description of the drawings
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of the online turbidity meter of lower range low-power consumption of the present invention.
Fig. 2 is the structural representation of snoot of the present invention.
Embodiment
Refer to shown in Fig. 1, a kind of online turbidity meter 100 of lower range low-power consumption, including upper shell 1, lower house
2nd, signal processing module 3, snoot 4, LED 5, collimation lens 6, the support 8 of detector 7 and one；Have one in the lower house 2
Measuring cell 21, the signal processing module 3 is located at the top of upper shell 1；The snoot 4 is fixedly connected in upper shell 1,
The inside of snoot 4 is provided with a current stabilization module 9, and the current stabilization module 9 is connected with signal processing module 3；The LED lamps 5 are embedding
It is connected in snoot 4, and with the current stabilization module 9；The collimation lens 6 is correspondingly arranged at the underface of snoot 4, and position
In the top of measuring cell 21；In the bottom insertion measuring cell 21 of the detector 7, the top of the detector 7 is anchored on upper shell
1, and the detector 7 is connected with signal processing module 3.
Referring again to Fig. 2, the snoot 4 includes a connecting portion 41 and a cover body 42, and the top surface of the cover body 42 is downward
Depression forms ground recess 421, and the center of the recess 421 is provided with an open-work 422, and the current stabilization module 9 is placed in the recess 421
Interior, the LED 5 is embedded in open-work 422；The connecting portion 41 and cover body 42 are detachably connected, the outer wall ring of the connecting portion 41
Provided with a groove 411；One end of the support 8 is embedded in the groove 411, and the other end is fixed on upper shell 1.The snoot
4 be stainless steel.
Referring again to Fig. 1, when application present invention work, host computer (not shown) is given in upper shell 1 by cable 10
Signal processing module 3 is powered, and light source led lamp 5 is opened, after snoot 4 carries out preliminary optically focused, then by collimation lens 6 two
After secondary optically focused, light beam is with vertical angular illumination into the solution to be measured in the measuring cell 21 in lower house 2, and light beam passes through water body
In turbidity standard material (formal hydrazine) scattering, light is received by the detector 7 in 90 degree of directions.Detector 7 is according to light
On intensity, feedback voltage signal to signal processing module 3, after a series of processing and computing, host computer is transferred to.
The light source of turbidity meter 100 needs stabilization, so that the problem of avoiding null offset and measurement fluctuation, the present invention
Measurement range be 0.001-100NTU, in low magnitude portion, the light sent with light source is received in 90 ° of detector 7
Signal is very faint, so the stability of light intensity and the Weak Signal Processing received are quite important to the precision of low magnitude portion, it is right
In the control of light intensity, signal processing module 3 has done voltage stabilizing processing, after the burning voltage through processing to current stabilization module 9, there is steady again
Stream process, after voltage stabilization and current stabilization is handled, influence of the light source in terms of driving has carried out maximum suppression.Light source is LED
Lamp 5 has heat and distributed in itself, and temperature has an impact to LED, and snoot 4 is stainless steel, both ensure that cooling requirements, has again
Etch-proof effect, and snoot 4 can play preliminary optically focused effect, and also the heat distributed can be heated to collimation lens 6,
So that the probability reduction that collimation lens 6 is atomized, atomization can influence the intensity of light.
The turbidity meter 100 of existing tungsten lamp needs 15W power consumption, and the power consumption of LED only needs to 2W, power consumption drop
To original 21.6%, 78.4% have dropped.According to the service life of different use environment tungsten lamps on 6 months to a 1 year left sides
It is right.And the LED theoretical life-span is 100,000 hours, maintenance period extension 2-3.
