Description
Technical field
The utility model relates to field of water quality detection, in particular to a kind of water quality detection sensor.
Background technique
For water quality detection, usual method is to utilize reagent.This method and step is cumbersome, is not suitable for for on-line checking.
And reagent is consumables, goes down for a long time, can make a very big consumption, will increase the burden of enterprise, also, actually detected need
The plenty of time is consumed, waiting period is long.
Utility model content
For the above defect of the existing technology, the main purpose of the utility model is to overcome the deficiencies in the prior art
Place, discloses a kind of water quality detection sensor, including handle and setting be in the first light path and the second light path,
Setting is for switching the switching switch of the first light path and the second light path on the handle；
First light path includes the first stepped shell, is arranged on first shell mutually perpendicular
First inspection door and the second inspection door, and in the first inspection door setting 300nm ultraviolet filter and to outside first shell
The 280nm light source of irradiation, the second inspection door setting ultraviolet band pass filter and the first photodiode；
Second light path includes stepped second housing, is arranged on the second housing mutually perpendicular
Third inspection door and the 4th inspection door, and in third inspection door setting 360nm narrow band filter and to outside the second housing
The 360nm light source of irradiation, the 4th inspection door setting 415-580nm bandpass filter and the second photodiode；
Further, the 280nm light source and the 360nm light source are LED light source.
The utility model obtain the utility model has the advantages that
The utility model by humic acid in Fluorometric assay water, fulvic acid, hydrophily organic acid, nucleic acid, amino acid and
The concentration of the substances such as surfactant obtains the COD value in water quality indirectly, to achieve the purpose that detect water quality.And pass through
Handle connection, facilitates operation, and switching switch is arranged, and can according to need carry out selective enumeration method.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
A kind of water quality detection sensor of the utility model, as shown in Figure 1, including handle 1 and setting in the first detection
Optical path 2 and the second light path 3, setting is switched for switch the switching of the first light path and the second light path on handle；
Switched between the first light path 2 and the second light path 3 by switching switch, so to the concentration of different impurities in water into
Row detection.Improve detection range.
As shown in Fig. 2, the first light path 2 includes the first stepped shell 21, it is arranged on the first shell 21 mutual
Perpendicular the first inspection door and the second inspection door, and in the first inspection door 300nm ultraviolet filter 22 is set and to first
Ultraviolet band pass filter 24 and the first photodiode 25 is arranged in the 280nm light source 23 of shell external exposure, the second inspection door；Its
In, 280nm light source 23 is LED light source；The light issued by the light source 23 of 280nm carries out green by 300nm ultraviolet filter 22
Light detects the light in water by ultraviolet band pass filter 24 by the first photodiode 25, detects class ammonia in water
Base acid substance concentration.
As shown in figure 3, the second light path 3 includes stepped second housing 31, it is arranged on second housing 31 mutual
Perpendicular third inspection door and the 4th inspection door, and in third inspection door 360nm narrow band filter 32 is set and to second
415-580nm bandpass filter 34 and the second photodiode is arranged in the 360nm light source 33 of shell external exposure, the 4th inspection door
35；Wherein, 360nm light source 23 is LED light source；It is right by 415-580nm bandpass filter 34 by the second photodiode 35
Light in water is detected, and humic acid and fulvic acid concentration in water are detected.
Operator holds handle 1, the first light path 2 and the second light path 3 is immersed in the water of detection, by cutting
The working condition of switching two-way light path is changed, and then detects water quality situation.
The above is only the preferred embodiments of the utility model, are not used to limit the scope of the utility model；If
The spirit and scope for not departing from the utility model, are modified or replaced equivalently the utility model, should all cover in this reality
In novel scope of protection of the claims.
