Description
Technical field
The utility model relates to sensor technical field, is specifically related to a kind of water quality sensor.
Background technology
Water quality monitoring monitors and measures the kind of pollutant, the concentration of each pollutant and variation tendency in water body, the process of evaluating water quality situation, the main monitoring project of water quality monitoring can be divided into two large classes: a class is the overall target of reflection water quality condition, as temperature, colourity, turbidity, pH value, conductivity, suspension, dissolved oxygen DO, chemical oxygen demand (COD) and BOD etc.; Another kind of is some noxious materials, as phenol, cyanogen, arsenic, lead, chromium, cadmium, mercury and organic agricultural chemicals etc.For the situation of objective appraisal rivers and ocean water quality, except above-mentioned monitoring project, sometimes need the mensuration of carrying out flow velocity and flow.Traditional water quality sensor, its structure comprises water quality sensor main body, cable and electrode surface, sensor electrode is had near its electrode surface, the water quality information detected, after the signal processing means processes of water quality sensor inside, is sent to beyond water quality sensor by sensor cable by the water quality information that sensor electrode detects.
The water quality sensor function ratio of prior art is more single; generally there are special pH value sensor, hardness transducer, dissolved oxygen sensor etc., and adopt between protective cover and sensor body and be threaded, in the impact of buoyancy and current; protective cover easily gets loose, and makes troubles to monitoring.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, provides the water quality sensor that a kind of structure is simple, reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is: it comprises cable, fixed mount, sensor mobile jib, electrolytic solution, anode, negative electrode, protective cover, snap fit, pH value warning device, thermistor, O-ring seal, oxygen permeation membrane, hardness warning device, probe, one end of described sensor mobile jib is connected with cable, fixed mount is provided with between cable and sensor mobile jib, the other end of sensor mobile jib is provided with probe, described probe comprises anode, negative electrode, probe upper end is disposed with hardness warning device from top to bottom, pH value warning device, thermistor, the outer cover of probe is provided with protective cover, protective cover and sensor mobile jib are by snap fit clamping, protective cover and sensor mobile jib junction are provided with O-ring seal, the end of protective cover is provided with oxygen permeation membrane, described fixed mount and protective cover adopt anti-corrosion material to form.
During the utility model operation; because the oxyty in water is subject to the impact of water temperature; thermistor can carry out the temperature compensation of uniform temperature automatically; be conducive to Accurate Analysis; simultaneously; pH value warning device and hardness warning device are monitored the pH value of water quality and hardness, and snap fit is convenient to change electrolytic solution, and protective cover can not be got loose.
After adopting said structure, the beneficial effect that the utility model produces is: the multi-functional dissolved oxygen sensor of one described in the utility model, there is pH value automatic alarm and hardness auto-alarm function, compact conformation, not slippage, easy for installation, replacing electrolytic solution is convenient, the utility model have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
