Description
Technical field
The utility model relates to dissolved oxygen sensor field, particularly relates to one and possesses cleaning function dissolved oxygen sensor.
Background technology
When water environment in-site measurement dissolved oxygen DO, need to use dissolved oxygen sensor, the place of particularly some aquacultures, often need the dissolved oxygen DO in Real-Time Monitoring water.
Mostly existing dissolved oxygen sensor is to adopt places anode in the electrolytic solution and negative electrode and directly responds to dissolved oxygen DO in water, sensor is placed in water, water enters and contacts with oxygen permeation membrane after the filtration of filter screen, owing to often having impurity and little biology in water, easily oxygen permeation membrane is blocked, even damage oxygen permeation membrane, affect the detection of dissolved oxygen DO, so need usually to clean oxygen permeation membrane, but by sensor, from taking out, to remove filter screen be a loaded down with trivial details process, and monitoring will be interrupted, very inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide one and possesses cleaning function dissolved oxygen sensor, and structure is simple, carries the cleaning structure of oxygen permeation membrane, is not interrupting cleaning oxygen permeation membrane under the prerequisite of monitoring, is ensureing the long-term normal work of sensor.
The utility model solves the technical scheme that its technical matters adopts: provide one to possess cleaning function dissolved oxygen sensor, comprise shell, filter screen and anode, described shell is the right cylinder of inner hollow, detachably filter screen is installed bottom it, the top of this filter screen is provided with oxygen permeation membrane, inner chamber and the oxygen permeation membrane of described shell surround electrolyte cavities, vertically anode is installed in the middle part of this electrolyte cavities, the lower end of this anode is furnished with negative electrode, the side of this anode is vertically furnished with thermistor, the upper end of described electrolyte cavities is the water-proof sealing block being embedded into enclosure, the top of described shell is embedded with the waterproof plug that lower end and water-proof sealing block withstand between two parties, described anode, the electric wire that negative electrode is connected with the upper end of thermistor is by being connected with the external world through waterproof plug after water-proof sealing block again, the middle part of described filter screen is vertically installed with rotating shaft, the lower end of this rotating shaft is connected with the power blade of outer side, the upper end of this rotating shaft has one end of purge block to be connected with horizontally disposed, the upside of this purge block contacts with the lower surface of oxygen permeation membrane all the time.
As a kind of preferred version of the present utility model, described power blade to be evenly arranged around rotating shaft by several one piece blades and to form.
Supplement as one of the present utility model, described anode is helical structure.
Supplement as another kind of the present utility model, ringwise, its side is connected with water-proof sealing block by straight line pole described negative electrode.
Further, the sidewall of described shell has electrolytic solution inlet.
Further, the outside of described waterproof plug is densely covered with protruding ring, improves the waterproof effect of waterproof plug.
The utility model structure is simple, carry the cleaning structure of oxygen permeation membrane, utilize the movement of sensor in water that power blade is rotated dexterously, thus cleaning structure work is cleaned oxygen permeation membrane, do not interrupting cleaning oxygen permeation membrane under the prerequisite of monitoring, also utilize waterproof plug and water-proof sealing block to carry out dual waterproof, ensure the long-term normal work of sensor.
