A family-style small-scale water transparency detector is composed of a bow-shaped metal tube and a cylindrical black glass tube. One end of the bow-shaped metal tube has a metal tube handle and a photoresistor device, and the other end is a laser light device. There is a hollow cylindrical protrusion at the photoresistor and laser light assembly. The distance between the two ends of the bow-shaped metal tube is adjusted by a metal rod with a screw. The surface of the cylindrical glass tube is black and opaque, and the two ends of the cylindrical glass tube are concave and closed. There is a small cylindrical hole in the middle of the curved surface of the cylindrical glass tube to inject the water to be measured. The laser light is connected in parallel with the photoresistor, and the laser light is connected in series with the ammeter. The beam emitted by the laser light shines on the photoresistor through the water body to be measured. The size of the photoresistor is different through the difference in light intensity, and then the current in the circuit is changed. The turbidity level of the water is divided according to the size range of the current. Criteria for judging the transparency of water bodies.
Description
Technical field
The utility model relates to a kind of family small water transparency detector, is a kind of a kind of electronic device that can carry out bigness scale to the transparency of domestic water specifically.
Background technology
Because the raising of social life quality, people are also increasingly high for the requirement of domestic water.But the excellent and difference of the quality of water does not have certain judgment criteria, has brought the blindness of domestic water, has brought certain threat for people's life and health.In addition, the large-scale precision water quality testing meter that exists at present is not suitable for family owing to cost an arm and a leg, and can't carry out penetration and promotion to this.
Summary of the invention
The problem that can't pass judgment on the quality of domestic water to present people; The utility model provides a kind of family small water transparency detecting device; This instrument can be to the in addition bigness scale of the transparency of some domestic waters, and the level of transparency through the screen display water outlet.
The technical scheme that its technical matters of the utility model solution is taked is: this structure is made up of an arc metal tube and a cylindrical black glass pipe; One end of arc metal tube has a metal tube handle and photoresistance device, and the other end is a laser lamp device.The two ends of arc metal tube are on same the straight line.The cylindrical protrusions that a hollow is arranged at photoresistance and laser lamp device place.Arc metal tube is made up of the different square metal tube of two joints; Two square metal tubes are connected together by a Metallic rod that has screw; Metal tube at one end has a nut and this Metallic rod to link together outward, regulates the spacing between the arc metal tube two ends through the rotation of nut.Metal tube handle rear end is a battery case, and 3～4 joint button cells can be housed, and metal tube handle front end is a liquid crystal electron screen.Be equipped with a pushbutton switch in metal tube handle interposition.The surface of cylindrical glass tube is that black is lighttight, and the two ends of cylindrical glass tube are that spill is sealed.In the middle of the curved surface of cylindrical glass tube, a cylindrical aperture is arranged, be used for injecting water body to be measured.With a rubber plug this hole plug is prevented exposing of water body.
The ultimate principle of this detector is, laser lamp is parallelly connected with photoresistance, and laser lamp is connected with reometer.Laser lamp emission light beam sees through water body to be measured and is radiated in the photoresistance; Difference through intensity of illumination makes that the size electricity of photoresistance is different; And then the size of electric current in the change circuit, the turbidity rank of dividing water according to the magnitude range of electric current is used as the discrimination standard of water transparency.The turbidity of water is low more, and the illumination that sees through glass container is just strong more, and the resistance of photoresistance is just more little, and is just big more through the electric current of circuit, otherwise the turbidity of water is high more, just more little through the electric current of circuit.The turbidity of water is divided into 4 normative references, be respectively excellent, good, in, poor.The range of current that each normative reference is corresponding certain respectively, this will confirm according to physical circuit.Testing result through LCDs output water transparency excellent, good, in, poor.
The beneficial effect of the utility model is: this small water transparency detecting device can detect different water bodys; The water transparency result of bigness scale provides certain normative reference can for people's domestic water, and this instrumentation is simple, simple structure; Cost is lower, is easy to promote.
