Programmable controller 7 connects with first centrifugal submersible pumps 3 and second centrifugal submersible pumps 4 communication respectively；
The utility model, which can be realized, is rinsed cleaning to the ventilated membrane of dissolved oxygen sensor 1, and to the first filter gauze 5,
Two filter gauzes 6 have reverse flow water pre-washing function, so as to keep passing the cleaning of dissolved oxygen sensor oxygen permeation membrane, reduce dissolved oxygen sensing
The maintenance of device 1, reduce by the first filter gauze 5, the possibility that the second filter gauze 6 blocks.
The Clean cover 2 is airtight cavity, and the dissolved oxygen sensor 1 is contained in airtight cavity, on the Clean cover 2
Offer first interface 8 and second interface 9；One end of first centrifugal submersible pumps 3 connects with the first interface 8, separately
One end is connected with first filter gauze 5；One end of second centrifugal submersible pumps 4 connects with the second interface 9, separately
One end is connected with second filter gauze 6.
It should be further stated that Clean cover 2 is the heavy metal cavity of a sealing, such as the material such as copper, stainless steel
Material is made.Sensor cable line outlet 11 is offered on the Clean cover 2.
As shown in Figure 1 or 2, in the present embodiment, the dissolved oxygen sensor 1 inside Clean cover 2 is set, sensor can be passed through
O-ring seal 12 is sealed.
The first interface 8 is opened in the Clean cover 2 on the side of upper surface, and the second interface 9 is opened in
On the lower surface of the Clean cover 2.In the present embodiment, the sensor oxygen permeation membrane 10 on the dissolved oxygen sensor 1 is close to described
Second interface 9 is set.The distance in the lower end of the dissolved oxygen sensor 1 to the interior lower end face of Clean cover 2 is 1 millimeter to 3
Millimeter.Preferential 1.5 millimeters or 2 millimeters.This purpose done is dissolved oxygen sensor 1 is built in Clean cover 2, and with cleaning
Cover 2 interior lower end faces and form stenosis C；So that strengthen current washes away dynamics.Device provided by the utility model can be placed
In water body, the depth suitable with the activity in depth of the hobby such as material culture fishes and shrimps.
For the utility model is described in detail, now its operation principle is described further as follows：First centrifugal submersible pumps 3
It is small-sized DC immersible pump with second centrifugal submersible pumps 4.
It is as shown in Figure 1 self-stripping unit forward direction water flow structure schematic diagram, wherein, the direction shown in A is：Positive current side
To, in the case where second centrifugal submersible pumps 4 do not work, start the first centrifugal water pump work, draw through first filter
The water that clear net 5 filters, to the pump water of first interface 8 on the Clean cover 2, washes away dissolved oxygen sensor 1, process is narrow under current direction
Narrow place C, and produce larger water flow pressure in stenosis C and rinse sensor ventilated membrane, current play scour sensor ventilated membrane
Effect, and by water after the second interface 9 of Clean cover 2, second centrifugal submersible pumps 4 and second filter gauze 6
Stream discharge.The main function of the step is to clean sensor oxygen permeation membrane 10 using the current after the filtering of the first filter gauze 5, and is had
The effect of the second filter gauze 6 is cleaned, this effect is explained below；And provide necessary circulating water for sensor test.
Self-stripping unit reverse flow structural representation as shown in Figure 2, wherein, the direction shown in B is：Direction current side
To in the case where first centrifugal submersible pumps 3 do not work, the second centrifugal submersible pumps 4 of startup work, and draw through second
The water that filter gauze 6 filters, to the pump water of second interface 9 on the Clean cover 2, washes away dissolved oxygen sensor 1 on current direction, passes through
Stenosis C, and by water after the first interface 8 of Clean cover 2, first centrifugal submersible pumps 3 and first filter gauze 5
Discharge.The main function of the step is to utilize the current after the filtering of the second filter gauze 6 to rinse the first filter gauze 5, while to pass
Sensor test provides necessary circulating water.
With reference to above-mentioned, no matter positive or reverse flow, the equal relative clean of water in Clean cover 2.When first centrifugal
Immersible pump 3 worked after a period of time, meeting adsorption particle, pasture and water, feed, growth microorganism at the flow inlet of the first filter gauze 5
Deng the blocking of the first filter gauze 5 can be caused for a long time.When the second centrifugal water pump work, caused current are for the first filter
Clear device plays the role of inversely to clean, and is blown away equivalent to the particle for adsorbing the first filter gauze 5, so as to complete to the first filter gauze 5
Cleaning.Conversely, after the second centrifugal submersible pumps 4 work long hours, adsorb the second filtering flow inlet particle, pasture and water,
Feed, the microorganism grown etc., the current as caused by the first centrifugal submersible pumps 3, the second filter gauze of back flush 6.In addition, work as
After first centrifugal submersible pumps 3 and the second immersible pump are stopped, the water in Clean cover 2 is not exchanged with water body or slowly handed over
Change, the microorganism contained by water in Clean cover 2, killed by the heavy metal ion of Clean cover 2 (it is well known that using the copper fire hose
Head is not allowed to be also easy to produce microorganism) so as to be not easy to grow, due to the opposing seal of Clean cover 2, and bimodal current passes through filter gauze,
The chance being contaminated wherein built in sensor substantially reduces.
Immersible pump control figure is illustrated in figure 3, by power supply 13 and programmable controller 7, the first centrifugal submersible pumps 3,
Two centrifugal submersible pumps 4 form, and the purpose is to centrifugal latent according to certain the first centrifugal submersible pumps of rule control 3 and second
The unlatching and stopping of water pump 4.For example, allowing the second centrifugal submersible pumps 4 to work 10 times, the first centrifugal submersible pumps 3 work once,
So circulation.
Immersible pump control sequential figure is illustrated in figure 4, the second centrifugal submersible pumps 4 work 10 times, the first centrifugal diving
Pump 3 works once, so circulation, and user can be according to actual conditions, the work period of two immersible pumps of sets itself and duration.
It is further to note that when dive under water pump work when, in order to avoid immersible pump work interference dissolved oxygen sensor 1 work,
Selection is defined as first time collection point, second of collection point and n-th collection point after water pump stopping and before unlatching.
The utility model uses above technical scheme, can realize and be rinsed cleaning to the ventilated membrane of dissolved oxygen sensor 1, and
There is reverse flow water pre-washing function to the first filter gauze 5, the second filter gauze 6, so as to keep passing the clean of dissolved oxygen sensor oxygen permeation membrane
Only, the maintenance of dissolved oxygen sensor 1 is reduced, reduces by the first filter gauze 5, the possibility that the second filter gauze 6 blocks.In the utility model
Rinsed using filter water, pressure (hydraulic) water, heavy metal sterilization, positive and negative bimodal current, effectively inhibit the oxygen permeation membrane of dissolved oxygen sensor 1
The growth of upper microorganism, solve the filter net jam caused by unimodal current, greatly ensure that and keep continuous measurement accuracy
Generality problem.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw under enlightenment of the present utility model
Other various forms of products, however, make any change in its shape or structure, it is every that there is same as the present application or phase
Approximate technical scheme, all falls within the scope of protection of the utility model.
