Technical field
The utility model relates to a kind of automatic ship ballast water sampler.
Background technology
The ballast for cruising water sampling is meant certain device or the means of adopting, and obtains the biology of different size in the certain volume ballast water body.Existing various Ballast Water sampling technique mostly adopts manual or uses micro pump to obtain water sample, and then water body is filtered by the filter screen of different size; The sampler that perhaps will have filter screen places ballast tank, reclaims with certain speed then and carries out filtering and sampling.Ballast Water sampling guide rule G2 then requires: in whole discharge of ballast water process, sampler should be able to be collected the Ballast Water of the processing of certain volume, to be used for the inspection that meets of harbour state automatically certain moment at least three times.The Ballast Water sampler that can satisfy the requirement of sampling guide rule is not also arranged at present.
Summary of the invention
Can not in same water body, carry out continuously in order to overcome existing sampler, regularly, the deficiency of quantitative sampling, the utility model provides a kind of automatic ship ballast water sampler, this device can be installed in the discharge of ballast water pipeline easily, can easily obtain the Ballast Water of certain volume amount in some particular moment automatically, and finish then in same water body the filtration of two kinds of different size biologies is collected.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of automatic ship ballast water sampler, this device is by solenoid valve 1, Electromagnetic Flow 2, flow quantity control instrument 3, the PLC Programmable Logic Controller 4 of band liquid crystal display, water container 5, filtrator 6, solenoid directional control valve 7, filtrator 8, sample connection 9 and sampling line 10 are formed, the standard sample connection reserved in advance on stopple coupon 10 and the ship 9 is connected by flange, one end of solenoid valve 1 is connected with stopple coupon 10, the other end of solenoid valve 1 is connected with the import of electromagnetic flowmeter 2, the outlet of electromagnetic flowmeter 2 links to each other with water container 5, the control end of solenoid valve 1 links to each other with the PLC controller 4 of band liquid crystal display, the signal output part of electromagnetic flowmeter 2 is connected with flow quantity control instrument 3, the last limited signal of flow quantity control instrument 3 is connected with the PLC controller 4 of band liquid crystal display with reset signal, water container 5 is connected with filtrator 6, the lower end of filtrator 6 is connected by the entrance point of polyvinyl chloride pipe with solenoid directional control valve 7, a road of solenoid directional control valve 7 is output as the sampling passage, be connected with filtrator 8, another road is output as free passing away, and the control end of solenoid directional control valve 7 links to each other with the PLC Programmable Logic Controller 4 of band liquid crystal display.Water container 5 is a cone, and material is a Polyvinylchloride, is 1m highly, and the lower end has pipe thread.Filtrator 8 is a column type, and long is 100mm, and diameter is 60mm, the Polyvinylchloride material, and two ends are pipe thread.50 micron screen are equipped with in the lower end of filtrator 6, and 10 microns filter screen is equipped with in the lower end of filtrator 8.Filter screen can screw on and screw off easily, thereby changes.Water container 5, filtrator 6, solenoid directional control valve 7 and filtrator 8 can be connected in aggregates by pipe thread, and fix with quadra.Solenoid valve 1, electromagnetic flowmeter 2, the PLC Programmable Logic Controller 4 of flow quantity control instrument 3 and band liquid crystal display can be formed the sampling monitoring unit with placing in the square box.
The beneficial effects of the utility model are: can filter when collecting the certain volume water sample automatically, not only guaranteed to carry out at same water body the filtration collection of different size biosome, also the sample time that can save greatly, made things convenient for harbour state to meet inspection.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, solenoid valve, 2, electromagnetic flowmeter, 3, flow quantity control instrument, 4, the PLC Programmable Logic Controller of band liquid crystal display, 5, water container, 6, filtrator, 7, solenoid directional control valve, 8, filtrator, 9: sample connection, 10, sampling line.
Embodiment
In certain setting moment of discharge of ballast water, the PLC Programmable Logic Controller 4 of band liquid crystal display is controlled foremost solenoid valve 1 and is opened, the sampling beginning, electromagnetic flowmeter 2 begins to measure instantaneous delivery simultaneously, and measured value delivered to flow quantity control instrument 3, when flow quantity control instrument 3 is exported limited signal after accurately being accumulated to higher limit 100mL, the PLC Programmable Logic Controller 4 of band liquid crystal display is received the sampling passage that can close terminal solenoid directional control valve 7 behind the signal, the sampling water last sampler of can not flowing through, then the free passing away of flowing through.When integrated flow reaches another higher limit 1m
3The time, another goes up limited signal flow quantity control instrument 3 output, and the PLC Programmable Logic Controller 4 of band liquid crystal display is received the solenoid valve that can close behind this signal foremost, this sub-sampling end.The PLC Programmable Logic Controller 4 of band liquid crystal display can be exported reset signal simultaneously, with the flux cumulating value zero clearing of secondary flow quantity control instrument 3, prepares sub-sampling down.Sampling divides three times, respectively discharging Ballast Water total amount 10%, 50% and 80% o'clock, get two samples at every turn.
