Description
Technical field
The utility model relates to a kind of optical detection apparatus, the optical detection apparatus that especially convection cell detects.
Background technology
In the existing water quality inspection technique in market, a common detection cell is only furnished with a light source and a light inspection device.Materials different in fluid is different to the absorption of the light of different wave length, therefore the method that detects this material is in detection cell, to walk certain distance (being light path) with the detection light that it the most easily absorbs, by measuring by the intensity of the particular detection light of detection cell from the other end, calculate detection cell inner fluid to the consumption of light intensity (being light loss), and then calculate the concentration of this material of detection cell inner fluid.A detection cell is joined a light source and a light inspection device, has determined that a set of detection components can only rely on the parameter of a kind of light source detection of self.But a lot of situations need to detect in water two or more parameter, and this just needs two or more instruments, has greatly increased the required cost of installation and measuring instrument.Some parameter even needs the light of two kinds accurately to detect (as chemical oxygen demand COD, suitable to wavelength 600 μ m light detections in high concentration situation, suitable to wavelength 440 μ m light detections in low concentration situation), and must have severe toxicity (potassium dichromate) with detection reagent.It is few that this just requires instrument not only to consume amount of reagent, and measuring accuracy is high, and with low cost.Obviously, many instruments are measured simultaneously, these two kinds of methods of a plurality of measurement assemblies of separate unit instrument, and cost is high, reagent expends greatly, will by market, be eliminated gradually.Therefore few and can detect the detecting instrument of many kinds of parameters in the urgent need to consuming reagent.
Although instrument can be realized to the pick-up unit of such function on market, be characterized as a plurality of light sources and be fixed on a runner, by runner, rotate to realize a plurality of light sources and irradiate same detection cell.But its drawback is a plurality of light sources by Programming motor and then controls runner and do accurate rotation and realize, not only to control accurately the corner of runner, and need to remember accurately each light source position, software program is complicated, and along with using mechanical wear will inevitably make corner accuracy control, decline, cause the measuring error of instrument constantly to increase.
Summary of the invention
In order to overcome the problems referred to above, the utility model provides a kind of consumption reagent few, and can realize multiparameter and detect, the multiple light courcess cross detection device of separate unit instrument measuring multiple parameters.
The technical solution of the utility model is to provide a kind of multiple light courcess cross detection device, it comprises the holder of hollow, one detection cell is set in described holder, it is characterized in that: on described holder, be also provided with at least two light sources of aiming at described detection cell, described in each, light source correspondence arranges a light inspection device, the dead in line at the light source of each pairing and light inspection device place.
Preferably, described detection cell is right cylinder.
Preferably, the cylindrical that described holder is hollow, described detection cell is coaxial with described holder.
Preferably, the two ends of described detection cell by pipeline communication to outside described holder.
Preferably, described detection cell is spheroid.
Preferably, described detection cell is integrally formed by quartz glass.
Preferably, the wavelength of whole described light sources is differing from each other.
Multiple light courcess cross detection device of the present utility model passes through a plurality of light sources same position of cross-fire detection cell from different perspectives, the corresponding light inspection of each light source device.Like this, can pass through light sources with different wavelengths irradiating and detecting pond, thereby realize, do not change the detection that reagent can be realized multiparameter, also can realize gradation and detect different parameters, in the situation that not increasing detection cell volume, realize measuring multiple parameters, thereby greatly saved reagent, control flow and detection time.It is few that multiple light courcess cross detection device of the present utility model has the reagent of consumption, and can realize multiparameter detects, the advantages such as separate unit instrument measuring multiple parameters, and do not need complicated software control procedure not need power-equipment yet, thereby do not have the error that mechanical wear is brought.

Embodiment
Below embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 4, a kind of multiple light courcess 3 cross detection devices of the present utility model comprise the holder 1 of hollow, one detection cell 2 is set in holder 1, on holder 1, be also provided with two light sources 3 of aiming at detection cell 2, each light source 3 correspondence arranges a light inspection device 4, the dead in line at the light source 3 of each pairing and light inspection device 4 places.The light of each light source 3 transmitting different wave length, to realize the detection of difference in functionality.
In this most preferred embodiment, detection cell 2 is right cylinder.The cylindrical that holder 1 is hollow, detection cell 2 is coaxial with holder 1, the two ends of detection cell 2 by pipeline communication to holder 1.
Certainly, detection cell 2 can be also spheroid, and holder 1 can be also spheroid, can realize object of the present invention equally.
Detection cell 2 is integrally formed by quartz glass.
Certainly, detection cell 2 also can be bonded by a plurality of light transmissive materials.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
