Description
Technical field
The utility model is related to Internet of Things aquaculture field more particularly to dissolved oxygen sensors used for aquiculture.
Background technology
When water environment in-site measurement dissolved oxygen, need to use dissolved oxygen sensor, especially some aquacultures
Place, generally require in real time monitor water in dissolved oxygen.
Existing dissolved oxygen sensor is mostly molten in water directly to incude using the anode and cathode placed in the electrolytic solution
Oxygen is solved, is placed a sensor in water, water enters after the filtering of filter screen to be contacted with oxygen permeation membrane, due to often having impurity in water
It with small biology, is easy to block oxygen permeation membrane, or even damage oxygen permeation membrane, the detection of dissolved oxygen is influenced, so needing usually to saturating
Oxygen film is cleaned, but is a cumbersome process from dismounting strainer is taken out by sensor, and to interrupt monitoring, very not
It is convenient.
China Patent Publication No. CN105057248B discloses a kind of automatic washing device for dissolved oxygen sensor, packet
Include power output device, cleaning device and sensor connection protective device, it is characterised in that：The power output device includes passing
Moving axis, self-lubrication ceramic bearing, protective device-motor bin connector, magnetic coupling, motor bin and small-sized DC slow down electric
Machine scrubs dissolved oxygen sensor for providing power for cleaning device；Described sensor connection protective device one end and dissolved oxygen
Sensor threads are tightly connected, and the other end is connect with power output device thread seal, for being connected and fixed dissolved oxygen sensor
And cleaning device, realize the automatic washing of dissolved oxygen sensor.The utility model be a kind of achievable automatic washing and static seal,
And the automatic washing device for dissolved oxygen sensor with non-maintaining, self-lubricating and the characteristic having good stability.
The technical solution needs to use micro-machine and transmission shaft by the way that automatic brushing device is arranged on a sensor,
Structure is responsible for and is difficult to safeguard have much room for improvement.
Utility model content
The utility model in view of the deficiencies of the prior art, provides a kind of simple in structure, easy to disassemble and maintenance, and can
Realize the automatically cleaning dissolved oxygen sensor of hydraulic automatism cleaning oxygen permeation membrane.
To realize the utility model aim, following technical scheme is provided：A kind of automatically cleaning dissolved oxygen sensor, including circle
Tubular shell, cylinder shell bottom end oxygen permeation membrane, be rotatably connected in the protective cover of cylinder shell bottom end side wall, it is characterised in that protect
Shield bottom end seal, the left and right sides are symmetrically arranged with inlet and outlet, and the protective cover bottom end is provided with guide post, is arranged
In torsional spring, two pieces of returning face plates being articulated in guide post and one piece of fixed plate being fixed in guide post in guide post, two
Block returning face plate is connect with fixed plate by torsional spring, and returning face plate top is provided with Clean Brush for cleaning, Clean Brush for cleaning and ventilative film surface
It is in contact.
Preferably, returning face plate is both provided with the earhole hooked with torsional spring both ends with fixed plate surface.
Preferably, torsional spring is stainless steel.
It is screwed on the cooperation of the threaded hole of protective cover bottom end with corresponding open up preferably, guide post bottom end is threaded.
Preferably, returning face plate is rectangular or semicircle.
The utility model advantageous effect：The utility model is directed to guarantor of the impact flow characteristic in dissolved oxygen sensor of flow
One automatic brushing device is set in shield, can realize force direction automatic brushing downstream, and pass through itself at waterpower gap
Torsional spring effect is reversed scrub, effectively removes the impurity on oxygen permeation membrane, realizes forward and reverse scrub, substantially prolong oxygen permeation membrane
Service life, and be easily installed and dismantle.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 be guide post, returning face plate, torsional spring, Clean Brush for cleaning installation vertical view.
Specific implementation mode
Embodiment 1：A kind of automatically cleaning dissolved oxygen sensor includes the oxygen flow of cylinder shell 1,1 bottom end of cylinder shell
Film 2, is rotatably connected in the protective cover 3 of 1 bottom end side wall of cylinder shell, 3 bottom end seal of protective cover, and 3 left and right sides of protective cover is symmetrically set
Be equipped with water inlet 3.1 and water outlet 3.2,3 bottom end of the protective cover be provided with guide post 4, the torsional spring being sheathed in guide post 45,
Two pieces of returning face plates 6 being articulated in guide post 4 and one piece of fixed plate 7 being fixed in guide post 4, two pieces of returning face plates 6 with
Fixed plate 7 is connected by torsional spring 5, and 6 top of returning face plate is provided with Clean Brush for cleaning 8, and Clean Brush for cleaning 8 is in contact with 2 surface of ventilated membrane.
Returning face plate 6 is both provided with the earhole hooked with 5 both ends of torsional spring with 7 surface of fixed plate.Torsional spring 5 is stainless steel.4 bottom of guide post
End, which is threaded, to be screwed on corresponding open up with the cooperation of the threaded hole of 3 bottom end of protective cover.Returning face plate 6 is rectangular.
When the present apparatus is positioned in water body, when wave occurs in water body, the thrust of water enters from water inlet, pushes overturning
Plate is rotated around guide post, and to drive Clean Brush for cleaning forward direction to scrub, after water wave, torsional spring drives overturning sheet reset, to
It drives Clean Brush for cleaning reversely to be scrubbed, realizes the positive and negative scrub to oxygen permeation membrane.
