Abstract
The utility model discloses a device for rapidly detecting liquid safety. The device is characterized by comprising emission sources arranged in the same direction and more than one detector, wherein the emission sources generate electromagnetic waves; partial electromagnetic waves are reflected through a first liquid surface of liquid to be detected and are received by the detectors; partial electromagnetic waves are sequentially refracted by the first liquid surface of the liquid to be detected, reflected by a second liquid surface and refracted by the first liquid surface and are received by the detectors; and an identification module is arranged in the detector. The safety of the liquid is detected by utilizing the refractive index of the liquid; and the device is safe, convenient, easy to operate, can rapidly detect the liquid in a public place and has high practicality.
Description
Technical field
The utility model relates to a kind of device that fast and safely detects for liquid.
Background technology
Along with the development of society, human social activity is frequent, and mobility of people increases, so that the fast and safely detection of public place is become particularly important.People have been developed multiple measuring method for safety detection and instrument.Wherein of a great variety because of it to the detection of liquid, complicated component is relatively more difficult thing.Simultaneously liquids in general encapsulation is enclosed in the container, is subject to the chamber wall severe jamming of unlike material.Existing liquid detecting technology is mostly based on the detection to material composition and structure, because the liquid kind is very many, the other structure of material is very complicated, and most liquid is not pure state, mix with other liquid or material, more increased complicacy and the difficulty of composition detection.Therefore development based on new detection principle be applicable to fast and safely light checkout equipment of public place, have important actual application value.
Summary of the invention
The purpose of this utility model provides a kind of device of in public places fast detecting liquid.
In order to achieve the above object, the utility model provides a kind of device that fast and safely detects for liquid, it is characterized in that, be included in emissive source and the more than one detector arranged on the same direction, emissive source generates electromagnetic waves, and the part electromagnetic wave is detected device and receives through the first liquid level reflection of testing liquid, also have the part electromagnetic wave successively through the refraction of the first liquid level, the reflection of the second liquid level, the refraction of the first liquid level of testing liquid, be detected device and receive; Be provided with identification module in the detector.
Preferably, described detector is three.
Preferably, described electromagnetic frequency is 50k-150kHz.
The utility model detects according to macroscopical optical property of liquid, because dangerous liquid is normally low weight by element, active material strong, that bandwidth is higher forms, therefore its macroscopic reflectance data that show are less, and a little less than the activity of safe liquid, bandwidth is less, and its macroscopic reflectance that shows is larger.The electromagnetic wave of emissive source emission certain frequency, electromagnetic wave is detected reflection liquid in transmission course, detect reception by detector, according to the difference of the signal relative size of a plurality of detectors, there is identification module to judge the safe coefficient of identification liquid, then provides and report to the police and prompting.Emissive source and detector are positioned at same plane, can ignore in the reflection of horizontal 90-degree direction like this, therefore can reduce or ignore the contribution of chamber wall and disturb.
The utility model utilizes the refractive index difference of two liquid levels of liquid to come the security of tracer liquid, and is safe, light, easy operating, and fast detecting liquid has very high practicality in public places.
Description of drawings
The structural representation of a kind of device that fast and safely detects for liquid that Fig. 1 provides for the utility model.Among the figure:
1, emissive source; 23, the 3rd detector; 32, the second liquid level.
21, the first detector; 3, testing liquid;
22, the second detector; 31, the first liquid level;
Embodiment
For the utility model is become apparent, hereby with preferred embodiment, and cooperate accompanying drawing to be described in detail below.
Embodiment
As shown in Figure 1, the structural representation of a kind of device that fast and safely detects for liquid that provides for the utility model is included in the emissive source 1, the first detector 21, the second detector 22 and the 3rd detector 23 that are arranged in order on the same direction.
During detection, emissive source 1 produces the 50k-150kHz electromagnetic wave; The part electromagnetic wave is through the first liquid level 31 reflections of testing liquid 3, received by the first detector 21, the second detector 22, the 3rd detector 23 respectively, also have the part electromagnetic wave successively through 31 refractions of the first liquid level, 32 reflections of the second liquid level, 31 refractions of the first liquid level of testing liquid 3, received by the first detector 21, the second detector 22, the 3rd detector 23 respectively.The first detector 21, the second detector 22, the 3rd detector 23 are provided with identification module in receiving, and by the principle that identification module is set, the refractive index of identification testing liquid 3 judges whether it is dangerous material.
