Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of intelligent liquid level detection sensor.
The technical solution of the utility model is as follows：A kind of intelligent liquid level detection sensor, including：Liquid level sensor ontology,
Liquid isolated tube and filter sheath, the lower end of the liquid level sensor ontology are cased with liquid isolated tube, under the liquid isolated tube
End is also cased with filter sheath；The intrinsic lower section of liquid level sensor is equipped with pressure chamber, the intrinsic pressure of liquid level sensor
It is resonant cavity above power chamber, is isolated by flexible sheet between the pressure chamber resonant cavity, is set on the outer wall of the resonant cavity
Have a laser aligner, the one end of the laser aligner far from resonant cavity is equipped with optical fiber, in resonant cavity with the laser aligner
It is additionally provided with prism on corresponding position, floating block is additionally provided in the pressure chamber below the flexible sheet.
Further, the filter sheath is solid construction, and the upper surface of filter sheath is equipped with and liquid isolated tube lower end
Corresponding groove structure, for fixing filter sheath；The filter sheath is equipped with two through-holes up and down by entad, point
Not Wei water injection hole and gas vent, be designed with nut in the water injection hole and gas vent.
Further, the liquid isolated tube uses rubber tube, between liquid isolated tube and the liquid level sensor ontology
Equipped with rubber seal.
Further, the filter sheath is plastic construction, and filter sheath bottom is additionally provided with outwardly extending anticollision haptic element.
Using the above scheme, when the utility model is used, it changes due to measuring liquid level, floating block generates flexible sheet
One pressure deformation, when measuring, the reflected light of flexible sheet changes, and by being arrived by optical fiber transmission signal after dispersion
