Description
Technical field
The utility model relates to monitoring water quality on line equipment technical field, in particular to one kind automatically corrects type and dissolves online
Oxygen analyzer.
Background technique
Existing online dissolved oxygen analytic instrument, all uses sensor, and dissolved oxygen sensor is that one kind exists for measuring oxygen
The sensing equipment of meltage in water, but if long-term uninterrupted use, dissolved oxygen sensor signal is easy to produce drift, needs
Manual synchronizing periodically or is irregularly carried out, timing is needed for dissolved oxygen sensor to be placed in air from taking-up in water, be tieed up
Larger workload is protected, dissolved oxygen sensor measurement error is larger if correction not in time.
Summary of the invention
The utility model be in order to solve existing online dissolved oxygen analytic instrument correction dissolved oxygen sensor and need manual synchronizing,
The big problem of maintenance workload, providing one kind can be corrected automatically, without human intervention automatically correct the online dissolved oxygen of type
Analyzer.
To achieve the goals above, the utility model uses following technical scheme, and one kind automatically correcting the online dissolved oxygen of type
Analyzer further includes kickboard, fixed frame, sleeve, stepping electricity including interior analyzer ontology, the dissolved oxygen sensor for setting relay
Machine, upper cover, pulley, slip rope, the fixed frame are fixed in kickboard, and the sleeve, stepper motor are set on fixed frame, institute
It states sleeve top and is equipped with the rope hole passed through for slip rope, the fixed frame and kickboard, which are equipped with, to be cooperated with sleeve and can hold dissolved oxygen
The through-hole that sensor passes through, the stepper motor are equipped with volume cable pulley, and the pulley is set to sleeve top, the slip rope one
End is fixedly arranged on volume cable pulley, and the slip rope other end is fixed around on the outside of pulley and across rope hole with dissolved oxygen sensor, described
Stepper motor be electrically connected with relay, the upper cover and fixed frame cooperation fix.This programme uses designed structure, floats
Plate by whole device float on measurement the water surface on, and dissolved oxygen sensor be set to measurement underwater, can on-line testing water oxygen contain
Amount, and measuring signal is passed into analyzer ontology；In order to correct dissolved oxygen sensor, a settable period, by this
After period, analyzer ontology issues correction instruction, and relay is closed after instruction issues powers to stepper motor, stepper motor rotation
Turn regulation revolution, slip rope is recycled by volume cable pulley scrolling, and enters dissolved oxygen sensor from measurement underwater pull-up by pulley
In sleeve, through after a period of time, after water flow is most, analyzer ontology is corrected dissolved oxygen sensor, after the completion of correction, point
Analyzer ontology issues instructions to stepper motor again and reversely rotates regulation revolution, and after slip rope loosens, dissolved oxygen sensor is in gravity
Effect is lowered into measurement underwater, and relay, which disconnects, stops stepper motor rotation.
Preferably, the cartridges sides are equipped with multiple ventilation holes, it is long that the length sleeve is greater than dissolved oxygen sensor
Degree.Ventilation hole is conducive to dissolved oxygen sensor surface and air-dries, and improves correction accuracy, and dissolved oxygen sensor can entirely be detached from water
Face, surface water can also be dripped by the through-hole on fixed frame and kickboard.
Preferably, the analyzer ontology is equipped with temperature sensor.It is according to environment when correcting dissolved oxygen sensor
The relationship of oxygen content is reference with the locating actual ambient temperature of dissolved oxygen sensor itself come what is corrected in temperature and air,
Most accurately correction can be carried out to dissolved oxygen sensor；At the same time it can also detect water temperature amplitude of variation in temperature sensor
When being more than 5 DEG C with a preceding timing, start zero offset capability, this corrective command can be prior to the time interval of setting
It automatically corrects, after the completion of correction, water pump start-up operation is adopted in one minute, restores normal measurement.
Preferably, the kickboard is disc.
Therefore, the utility model has the following beneficial effects: (1) can be corrected automatically, without human intervention；(2) school
Positive combination site environment temperature, it is accurate.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model.
In figure: 1, dissolved oxygen sensor 2, kickboard 3, fixed frame 4, sleeve
5, stepper motor 6, upper cover 7, pulley 8, slip rope.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, one kind automatically corrects the online dissolved oxygen analytic instrument of type, including the interior analyzer ontology for setting relay,
Dissolved oxygen sensor 1, further includes kickboard 2, fixed frame 3, sleeve 4, stepper motor 5, upper cover 6, pulley 7, slip rope 8, and fixed frame 3 is solid
It being scheduled in kickboard 2, sleeve 4, stepper motor 5 are set on fixed frame 3, and 4 top of sleeve is equipped with the rope hole passed through for slip rope 8, Gu
Determine frame 3 and kickboard 2 is equipped with and cooperates and can hold the through-hole that dissolved oxygen sensor 1 passes through with sleeve 4, stepper motor 5 is equipped with volume rope
Wheel, pulley 7 are set to 4 top of sleeve, and 8 one end of slip rope is fixedly arranged on volume cable pulley, and 8 other end of slip rope is around 7 outside of pulley and passes through
Rope hole and dissolved oxygen sensor 1 are fixed, and stepper motor 5 is electrically connected with relay, and upper cover 6 and the cooperation of fixed frame 3 are fixed；
