Line will not change direction when propagating；If have suspended particulate, light beam when running into particle will the side's of change body (not tube particle it is transparent with
It is no), this just forms so-called scattering light, and the scattering of particle the more (turbidity is higher) light is just more serious, and turbidity is with a kind of referred to as turbid
Spend the instrument of meter come what is determined, nephelometer emits beam, and is passed through one section of sample, and from on direction of the incident light in 90 °
Detect that how many light is scattered by the particulate matter in water, according to thunder come scattering law, liquid is calculated by the scattered light intensity received
Turbidity.Turbidity is one of the parameter for reflecting liquid physical behavior, size, the shape of concentration, particle with suspended substance in liquid
Etc. relevant, such as in water quality detection, turbidity is to judge the very important index whether water quality pollutes.
In existing traditional online transmissometer, sensing arrangement include setting photosignal transmitter unit after the lens and
Photosignal receiving unit；In use, lens outer surface easily adheres to impurity, and then the normal propagation of interference light,
Make the light that receives smaller than actual light intensity, adhere to impurities accumulation, light attenuation is increasingly severe, so that Instrument measuring precision
It is more and more lower.

Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model provides a kind of light channel structure of scattering method on-line measurement liquid turbidity, including it is clear
Wash unit 1, sapphire lens 3, photosignal transmitter unit 2 and photosignal receiving unit 4；The sapphire lens 3 are set
In on the transmitting opticpath of the photosignal transmitter unit 2；The sapphire lens 3 are also provided at the photosignal and connect
On the reception opticpath for receiving unit 4；The wiper mechanism of the cleaning unit 1 acts on the sapphire lens 3 and measurement liquid
The contact surface of body.Angle is fixed between the photosignal transmitter unit 2 and photosignal receiving unit 4, preferably 60 degree.This
Utility model eliminates the interference of lens surface attachment impurity using cleaning mechanism, makes measurement result accurate, and saturating by sapphire
The cooperation of mirror 3 and cleaning mechanism, solves the effect of cut interference measurement results.Meanwhile by photosignal transmitter unit 2 and photoelectricity
Angle is fixed as 60 degree between signal receiving unit 4, helps to solve because the material refractive index of sapphire lens 3 influences testing liquid
The problem of 5 reflection, ensure 90 ° of refraction effects of testing liquid 5.
Specifically, the light channel structure of the present embodiment also includes fixed seat 6, and inner chamber is provided with the fixed seat 6, described
Photosignal transmitter unit 2 and photosignal receiving unit 4 are arranged on the interior intracavitary, described in the insertion of sapphire lens 3
The opening of the inner chamber and surface of the sapphire lens 3 is concordant with the lumen openings edge.Have two in fixed seat 6 shown in Fig. 1
The inclined hole (i.e. above-mentioned inner chamber) that individual fixed angle penetrates, two sapphire lens 3 are each passed through inclined hole and fixed, sapphire lens 3
One end face is perpendicular to the axis in hole, and other end is parallel with fixed seat 6 and micro- protrusion, so as to the outer surface of sapphire lens 3 with
The cleaning mechanism fitting of cleaning unit 1 is close, obtains more preferable cleaning effect.Photosignal transmitter unit 2 and photosignal connect
