Description

Water quality detector

technical field

The utility model relates to a water quality detector, in particular to a simple water quality detector suitable for use in villages and towns.

Background technique

With the development of industry, water pollution is becoming more and more serious. In some villages and towns, people often directly use water from wells, rivers, and lakes, and the water quality of these waters is often not up to standard. If people use it for a long time, it will seriously affect the health of humans and animals and the normal growth of crops, causing irreparable damage Loss.

At present, the structure and operation of water quality detectors are relatively complicated, and the price is very expensive, which is not suitable for use in villages and towns; at the same time, it is difficult for ordinary water quality detectors to accurately reflect the water quality of the water body because the electrode spacing of the detection sensor is below 10mm. Condition, not suitable for practical use.

Contents of the invention

The technical problem to be solved by the utility model is to provide a water quality detector, which has a simple structure, low cost, easy and accurate operation, and is suitable for use in villages and towns.

In order to solve the problems of the technologies described above, the technical solution adopted by the utility model is:

The water quality detector includes a shell, a power supply connected in series, a light bulb, an adjustable resistor and a detection sensor, wherein the power supply, the light bulb and the adjustable resistor are located inside the shell, and the detection sensor is located outside the shell, which consists of two pieces arranged in parallel composed of inert metal electrodes.

In the present invention, the distance between the two inert metal electrodes is 10-500mm.

The beneficial effects produced by adopting the above-mentioned technical scheme are: the utility model has a simple structure, and can intuitively reflect the resistivity of the water body and the turbidity of the water body through the brightness of the bulb, and qualitatively detect the water quality and water condition; the utility model is provided with an adjustable resistance , strong adjustability and wide application range; the distance between the two inert metal electrodes of the utility model is 10-500mm, which is more practical; the utility model is easy to operate and low in cost, and is very suitable for use in villages and towns.

Detailed ways

Referring to the accompanying drawings, the structure of a specific embodiment of the utility model includes a housing 5, a power supply 1 connected in series, a bulb 2, an adjustable resistor 3 and a detection sensor, wherein the power supply 1, the bulb 2 and the adjustable resistor 3 are located at Inside the housing 5, the detection sensor is located outside the housing 5, which is composed of two parallel inert metal electrodes 4, and the distance between the two inert metal electrodes 4 is 20 mm.

The working principle of the utility model is: an important index reflecting drinking water quality is the turbidity of the water body, and the resistivity of the water body can reflect its turbidity qualitatively, the higher the turbidity of the water body, the greater the resistivity, and the light bulb 2 is darker, when the resistivity reaches a certain value, the light bulb 2 will go out, indicating that the quality of drinking water is unqualified. In the process of specific use, according to the characteristics of water quality in different regions, the simple water quality detector can be calibrated by an accurate large-scale water quality detector, that is, the adjustable resistance of the utility model can be adjusted according to the measurement results of the large-scale water quality detector 3. Make the lighting and extinguishing of the light bulb 2 accurately indicate whether the water body is qualified or not.

In addition, the distance between the two inert metal electrodes 4 of the utility model can be selected between 10-500mm according to the actual situation; the power supply of the utility model can be a dry battery or a rechargeable lithium battery.

The above description is only proposed as an implementable technical solution of the present invention, and not as a single restriction on the technical solution itself.
