Embodiment
Embodiment 1:
As Fig. 1, the utility model design has the bulk container of three stainless steels, is respectively the preservation liquid container 3 that Klorvess Liquid is housed, the disinfectant container 15 that sodium hypochlorite or calcium hypochlorite thimerosal are housed, and the pure water container 16 that pure water is housed.The top of each bulk container all is equipped with a liquid injection port 1 and a vent port 2.The bottom design of these three containers becomes " pyramidal structure ", and connects solenoid valve 4 respectively.Utilize the PPR flexible pipe to connect between each solenoid valve and the integrated container 7.Various water quality sensors 6 are installed in the integrated container 7.The first half caliber of integrated container 7 is bigger, has the pipeline of four perforations, and wherein three link to each other with disinfectant container 15, pure water container 16 and the solenoid valve 4 of preserving liquid container 3 with the PPR flexible pipe respectively, and another is connected with water inlet peristaltic pump 10.The bottom of integrated container 7 is designed to " pyramidal structure " equally, adopts the PPR flexible pipe to be connected with water outlet peristaltic pump 9 equally.Elongated vent port 5 of the top design of integrated container 7, inside is equipped with level electrode 8.Water outlet peristaltic pump 9 and water inlet peristaltic pump 10 all are connected with rising pipe 11 and water inlet pipe 12.All peristaltic pumps 9,10 and solenoid valve 4 and each water quality sensor 6 all are connected on the acquisition controller 13 by cable 14, and this acquisition controller 13 adopts existing 8051F020 single-chip microcomputer to control peripheral components as CPU.
Preserving liquid container 3, disinfectant container 15 and pure water container 16 these three containers will try one's best greatly, to satisfy the needs of splendid attire liquid as much as possible, what adopt here is the cuboid container of 500mm * 400mm * 210mm, liquid capacity surpasses 50L under the situation of filled with fluid, prolongs whole device service time to greatest extent.The latter half unification of three bulk containers is designed to one " pyramidal structure ", adopts this design, can make things convenient for flowing of liquid, and no matter under which kind of situation, the liquid in the container can fully flow only.The tapered bottom end of each bulk container all connects a solenoid valve 4, under the control of solenoid valve 4, relies on self gravitation, and Klorvess Liquid, pure water, thimerosal are that the PPR of 10mm manages smoothly in the integrated container 7 of flow sensor via caliber all.All there is elongated tubular vent port 2 upper end of three bulk containers, communicates with atmosphere with assurance, and liquid can be flowed in the integrated container 7 smoothly.When high focal plane buoy is rocking in the process, such design is unlikely to again liquid is overflowed.Each container has a liquid injection port 1 again, can conveniently inject liquid, above with screwed lid sealing.
In the integrated container 7 various water quality sensors 6, for example pH sensor, conductivity sensor, dissolved oxygen sensor or the like can be installed.Can make full use of thimerosal (thimerosal can be selected sodium hypochlorite or calcium hypochlorite for use) like this, the working time of extension fixture, meet the reality of buoy work under bad environment, maintain and replace difficulty.Each sensor is parallel to each other, is vertically fixed on by screw thread on the upper end cover at integrated container 7 tops.
In integrated container 7 level electrode 8 is housed, whether the liquid that is used for testing in the integrated container 7 is filled with or emptying.In order to guarantee reliability, two level electrodes 8 are installed in integrated container 7 at least, if one of them goes wrong, remaining fluid potential electrode 8 can work on.
Embodiment 2: the anti-adhesion device using method of the utility model
The utility model is in order to prolong the afloat life cycle of various water quality sensors, reduce the maintenance cost of offshore set-up, do not adopt the conventional detection method that sensor is placed directly in the water, but underwater sensor is installed in the integrated container 7 of the above appropriate location of waterline, just touch seawater when having only measurement data.Under the control of acquisition controller 13, seawater is extracted in the integrated container 7 that various water quality sensors 6 are housed by water inlet peristaltic pump 10; Acquisition controller 13 sends startup command to various water quality sensors 6, gathers the various water quality datas of seawater; After collection is finished, with each data storage.Whole sampling finishes, and starts water outlet peristaltic pump 9, and the seawater in the integrated container 7 is extracted out; The situation that level electrode 8 is arranged light with seawater feeds back to acquisition controller 13, and acquisition controller 13 is opened the solenoid valve 4 of disinfectant container 15 then, and thimerosal is injected integrated container 7, and water quality sensor 6 is washed, soaks; Adopt sodium hypochlorite as thimerosal.According to its disinfection principle, after this chemical substance is decomposed environment is had no to pollute, therefore used thimerosal directly can be discharged in the seawater, needn't do any processing.
After the emptying thimerosal; Acquisition controller 13 is opened the solenoid valve 4 of the pure water container 16 that pure water is housed, and pure water is injected integrated container 7, and whole integrated container 7 and water quality sensor 6 flushings are soaked.This process mainly is that integrated container 7 and water quality sensor 6 are cleaned once more, prevents the last residual thimerosal that has of integrated container 7 inwalls and water quality sensor 6 probes, avoids the corrosion of residual disinfectancy liquid.It is found time with pure water at last.Finish to this flush cycle.But, it should be noted that owing to the sensor that obtains seawater pH value can not be exposed in the air, must be immersed in the neutral solution, guarantee its probe stable performance.After flushing finishes, need open the solenoid valve 4 of the preservation liquid container 3 that Klorvess Liquid is housed so, Klorvess Liquid is filled with integrated container 7.Before sampling beginning next time, earlier Klorvess Liquid to be found time, and then inject seawater and measure.
By the contrast experiment, use device of the present utility model after five months, sensor surface has only the sea life of minute quantity to adhere to, to not influence of measuring accuracy.And instruments such as existing current meter, thermohaline sensor, turbidity chlorophyll instrument, in the long equally time, a large amount of sea life of growth on the sensor surface, measuring accuracy descends significantly.
The utility model only just is immersed in sensor in the seawater when measuring water quality data, and sampling end back sensor enters the cleaning and dipping environment, can reduce the time of water quality sensor 6 in seawater greatly like this, thereby also reduce the growth time of marine growth on sensor; Antiseptic solution immersion sensor by fresh water and the growth of inhibition marine growth also can will kill attached to the marine growth on the sensor, thereby has cleaned the probe of sensor, the life cycle that can effectively prolong all kinds of underwater sensors.
