Description
Affiliated technical field
The utility model relates to a kind of water quality sensor, and specifically a kind of water quality sensor that has ultrasonic cleaning equipment, has function of on-line cleaning is applicable to the water quality sensor of environment such as sea-farming water quality detection, environmental protection water quality detection.
Background technology
Existing water quality sensor, its structure comprises water quality sensor main body, cable and electrode surface, near its electrode surface sensor electrode is arranged, the detected water quality information of sensor electrode is sent to detected water quality information beyond the water quality sensor by sensor cable after the signal processing means processes of water quality sensor inside.
As everyone knows, water quality sensor in the water quality monitoring is owing to be immersed in the tested water for a long time, have a lot of microorganisms and calcification material thereof attached to the water quality sensor electrode surface or between sensor electrode, changed former should detected water quality information, make the detected water quality information error of water quality sensor increase.The past people solution is to change and manually clean the probe that the water quality sensor strip has electrode termly, though yet can solve the problem of the accuracy of detection variation that water quality sensor produces owing to long-term work so to a certain extent in water, but finally all be unable to do without frequent manual maintenance, be difficult to realize the full automation of water quality detection, the cost of maintenance is also than higher.In addition, the frequent dismounting of water quality sensor and cleaning to also producing certain influence its serviceable life.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of water quality sensor that has ultrasonic cleaning equipment, has function of on-line cleaning is provided.The ultrasound wave that ultrasonic generator sends acts on the sensor electrode surface, plays the effect on cleaning electrode surface, makes it to keep clean, and guarantees the detection degree of accuracy of water quality information.
It is to be provided with a ultrasonic generator in the outside of electrode surface that the utility model solves the problems of the technologies described above the technical scheme that is adopted.Ultrasonic generator comprises: ultrasonic generator housing, ultrasonic vibrator, match circuit, ultrasonic emitting body, ultrasonic generator cable, the ultrasonic generator housing is connected and fixed by web member and water quality sensor main body, and the whole ultrasonic wave producer is positioned at the downside or the oblique downside of electrode surface.
When water quality sensor normally detected water quality information, ultrasonic generator was not worked.When water quality sensor carried out cleaning operation, ultrasonic generator was to water quality sensor electrode surface emission ultrasound wave.Near the water quality sensor electrode surface water sparse, the high density state of alternation can occur under the effect of ultrasound wave sound field.And exist the small cavity or the bubble of a large amount of non-steady states in the water, under the ultrasonic acoustic field action, these cavitys rise big rapidly and bury in oblivion, and make between the water particulate tens thousand of times fiercenesses collision took place in moment, produce very large energy.Microorganism that the electrode surface of the sensor that is cleaned adheres to and calcification material thereof will be separated under this strong cavitation soon.Like this, just reach the electrode surface of cleaning water quality sensor and the purpose of assurance water quality detection degree of accuracy.
When using ultrasound wave that the sensor electrode surface is cleaned, ultrasonic waves transmitted can reflect when arriving electrode surface, the ultrasound wave and the ultrasonic waves transmitted mutual superposition of reflection can produce standing wave, and this just makes hyperacoustic vibration amplitude become the strongest or the most weak in some stationary phase place mutual superposition.It is different will causing the cavitation at diverse location water like this, and then causes the uneven phenomenon of sensor electrode surface clean.The present invention has given one's full attention to this problem, and ultrasonic transmitter is designed to tapered plane or curved surface.Because ultrasound wave is along rectilinear propagation, its reflection supersonic wave of being returned by the sensor electrode surface reflection just can not meet with the emission ultrasound wave, just can not form standing wave yet, and then avoid cleaning the generation of non-uniform phenomenon.In addition, make the ultrasound wave of reflection can directly not reflex to the ultrasonic generator surface like this, thus the damage that the ultrasound wave that can avoid reflecting causes ultrasonic generator.
The beneficial effects of the utility model are that the ultrasonic cleaning water quality sensor electrode surface that utilizes ultrasonic generator to send has guaranteed the degree of accuracy that water quality information detects.Because water quality sensor itself has online ultrasonic cleaning function, has reduced frequent manual maintenance process, has saved a large amount of maintenance costs, has prolonged the effective storage life of water quality sensor in water, has realized the full automation of water quality detection.
