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 recess, and the center of the recess is provided with an open-work, and the current stabilization module is placed in the recess, the LED insertion
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 is embedding
Enter in the groove, the other end is fixed on upper shell.
Preferably, the snoot is stainless steel.
The utility model has the advantage of：
1st, power consumption is greatly reduced, have dropped 78.4%；
2nd, snoot plays preliminary condenser effect, and the heat distributed can heat to collimation lens, be atomized collimation lens
Probability reduce, atomization can influence the intensity of light.
Brief description of the drawings
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of the online turbidity meter of the utility model lower range low-power consumption.
Fig. 2 is the overall diagram of the utility model snoot.
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 are located at the top of upper shell 1；The snoot 4 is fixedly connected in upper shell 1, should
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 5 is embedded at
In snoot 4, and it is connected with the current stabilization module 9；The collimation lens 6 is correspondingly arranged at the underface of snoot 4, and positioned at survey
Measure the top in pond 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. 1-2, the snoot 4 includes a connecting portion 41 and a cover body 42, the top surface of the cover body 42 to
Lower recess forms 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 utility model works, host computer (not shown) gives upper shell 1 by cable 10
In signal processing module 3 power, light source led lamp 5 is opened, after snoot 4 carries out preliminary optically focused, then by collimation lens
After 6 secondary condensations, with vertical angular illumination into the solution to be measured in the measuring cell 21 in lower house 2, light beam passes through light beam
The scattering of turbidity standard material (formal hydrazine) in water body, light is received by the detector 7 in 90 degree of directions.The basis of detector 7
The intensity of light, on feedback voltage signal to signal processing module 3, after a series of processing and computing, it is transferred to host computer.
The light source of turbidity meter 100 needs stabilization, the problem of so as to avoid null offset and measurement fluctuation, this practicality
New measurement range is 0.001-100NTU, in low magnitude portion, is received with the light that light source is sent in 90 ° of detector 7
The signal arrived is very faint, so the stability of light intensity and the Weak Signal Processing received are quite heavy to the precision of low magnitude portion
Will, the control for light intensity, signal processing module 3 has done voltage stabilizing processing, through the burning voltage of processing to after current stabilization module 9, again
There is current stabilization processing, 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 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,
There is etch-proof effect again, and snoot 4 can play preliminary condenser effect, and also the heat distributed can give collimation lens 6
Heating, so that the probability that collimation lens 6 is atomized reduces, 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 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 theory life-span is 100,000 hours, maintenance period extends 2-3.
