The device comprises a tank body, a light emitting diode, a resistor, a light sensitive resistor, an amperemeter and a power supply, wherein the light sensitive resistor is arranged at the top of the tank body; the light emitting diode is arranged at the bottom of the tank body, and is vertical to the light sensitive resistor; the light emitting diode, a current limit resistor and the power supply form a light emitting path; and the light sensitive resistor, the amperemeter, the current limit resistor and the power supply form a detection path. In the liquid turbidity detection device, a photoelectric technology is adopted, and the liquid turbidity is tested by utilizing light penetrability and the situation that the light sensitive resistor generates resistance change when encountering light, so the device is convenient to operate and quick and practical.
Description
Technical field
The present invention relates to a kind of liquid turbidity pick-up unit, particularly water body turbidity pick-up unit, is to the innovation of liquid turbidity pick-up unit in the past, is particularly useful for the detection of waste water turbidity.
Background technology
The year the quickening of modern city process; high buildings and large mansions in blocks are rised sheer from level ground; the undue utilization exploitation in soil; produce a large amount of building waste water and sanitary wastewater; and environment caused severe contamination, along with the raising of people's environmental consciousness and the needs of protection water resource, recovery of Waste Water is also more and more paid attention to; but recycling the muddy degree that reaches after the waste water recovery, waste water all needs to monitor, with the processing mode of decision to waste water.To the detection of waste water, will take a sample earlier in the past, and take back laboratory assay then, cumbersome, consuming time, for this reason, designing a kind of device more convenient, that survey water chaotic degree efficiently becomes inevitable.
Summary of the invention
The purpose of this invention is to provide a kind of liquid turbidity pick-up unit, it adopts optical principle, causes that by the variation by the liquid luminous flux variation of electric current comes the tracer liquid turbidity, thereby makes that the muddy degree of tracer liquid can be more convenient and quick.
The technical solution used in the present invention:
A kind of liquid turbidity pick-up unit, comprise casing, light emitting diode, photo-resistor, galvanometer, power supply, it is characterized in that photo-resistor being set at the top of casing, at bottom half light emitting diode is set, light emitting diode is corresponding with the photo-resistor position, all places on the vertical line of casing middle part.Light emitting diode is connected in series with current-limiting resistance and constitutes luminous widely different road with power supply; Photo-resistor is connected in series with galvanometer, current-limiting resistance and constitutes the widely different road of detection with power supply.Calculate by the decay that current produce luminous flux by photoresistance and light emitting diode, and embody demonstration intuitively by the variation of light flux variations generation electric current.
Described casing is a seal case, reaches the black lucifuge layer that extinction is set on the top around casing, to avoid reflection of light, improves the precision that detects; Described power supply is luminous widely different road and detects the shared power supply in widely different road.Be respectively equipped with the water proof glass plate at casing inner top and bottom, so that photo-resistor and light emitting diode and detected liquid are separated.
Adopt current-limiting resistance directly to flow through in the circuit as electronic component restriction electric current.Guarantee that the magnitude of current is unlikely to excessive.
Switch is set so that detect at any time, saves the power consumption of power supply, and can conveniently detect.
During operation, switch is in off-state, the test casing is put in the liquid that need test, treat that liquid fills with after the whole box body switch opens.After the switch opens, proving installation begins to test, undertaken luminous by light emitting diode, light passes liquid, under the effect of photoresistance, the widely different road of photoresistance electric current changes the variation of corresponding current then, with the luminous flux of electric current pointed correspondence, just can learn the muddy degree of liquid.
Beneficial effect of the present invention: the present invention is simple in structure, practicality is reliable, and its photoelectric technology detects liquid turbidity, and is convenient, fast, save time.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The contrast accompanying drawing specifies its structure.
In Fig. 1, light emitting diode 1 and photo-resistor 2 are fixed on to be installed on the casing 3, and the black lucifuge layer of extinction is set around casing
To avoid the influence of reflection of light effect to the detection degree of accuracy, power supply 7 is supplied with luminous widely different roads and is detected the electricity consumption of widely different road, photo-resistor 2 and galvanometer 4, and resistance flowing resistance 5 and power supply formation detect widely different road; Light emitting diode 1, current-limiting resistance 6 constitute the widely different road of detection with power supply.When the test casing is put in the tested troubled liquor, after treating that liquid is filled whole test casing, switch 8 is opened, circuit is tested, luminous flux causes that the variation of electric current shows by the galvanometer variation, calculate by electric current and luminous flux, calculate luminous flux, and by and the luminous flux that changes of liquid between get in touch, be converted into the turbidity of liquid, just can detect the muddy degree of detected liquid, be respectively equipped with water proof glass 10, so that photo-resistor and light emitting diode and detected liquid 9 are separated at casing top and bottom.
