Water sampler of the present utility model is arranged in hull, together navigates by water with ship.
The specific works process of water sampler of the present utility model is as follows:
The first, the free end of pumping conduit is transferred to (degree of depth of specifying) in the waters of assigned address.
Second electromagnet of each closed water sampling device is just energized, and the second iron plate 517 is adsorbed on dividing plate 53, thus whole hydrophore 51 is adsorbed, is fixed on dividing plate.
The second, drive first piston body 3 up to move by lifting actuating unit 1, until first piston body is resisted against on annular stop projection 92, now, first piston body moves in sampling import and export, and shutoff sampling is imported and exported.
3rd, open water pump, make water in designated depth waters by the suction of pumping conduit port, and entered pumping conduit successively, water pump, connecting hose and inlet through hole enter in the inner chamber of vertical water storage cylinder 9; Then, the water in vertical water storage cylinder is upper unrestrained gradually, and is discharged by water delivering orifice 93 and drainage pipeline 10.The water of being discharged by drainage pipeline 10 can directly be expelled back into through the country.
Then get off in the process of work at water pump, pumping conduit, water pump, the water that the air in connecting hose and vertically water storage cylinder inner chamber is designated in basin is discharged completely.(in this process because hydrophore 51 adsorbs, is fixed on dividing plate by the second electromagnet, hydrophore can be avoided at buoyancy float downward)
4th, the first electromagnet energising of one of them closed water sampling device, now its first iron plate moves down under the suction of the first electromagnet, and drives the second piston body 512 to move down by connecting guide rod 513, thus the mouth of a river 511 is adopted in unlatching; Now, adopt inert gas in the water storage cavity of water drum and discharge (being full of inert gas in the water storage cavity adopting water drum), the water in vertical water storage cylinder is adopted automatically flowing in the water storage cavity of water drum.
Due to now vertically the water of water storage cylinder inner chamber also not with contacting external air, thus effectively can avoid the water sample that gathers in marine site and contacting external air and be interfered in water sampling process, thus improving authenticity, the validity that water sample analysis result represents water environment.
5th, the first electromagnet power-off of this closed water sampling device, now under the effect of Compress Spring, the second piston body up moves to and adopts in the mouth of a river, and the mouth of a river is adopted in shutoff.
6th, the second electromagnet power-off of this closed water sampling device, now the hydrophore 51 of this closed water sampling device is at buoyancy float downward, and along current successively through water delivering orifice and the drainage pipeline of vertical water storage cylinder, and discharged by the port of drainage pipeline; So far complete in the sampling process of a water sample.
7th, after completing the sampling of a water sample, water pump cuts out; And the water in vertical water storage cylinder is discharged by water through hole and lower water tube hose by opening switch valve.Because first piston body upper surface is provided with several closed water sampling devices, thus only need return the 3rd step in upper once employing and operate.
