Description
Technical field
The present invention relates to a kind of water sampling device is and in particular to a kind of closed seawater sampler.
Background technology
Waters water body is affected to produce layering effect by factors such as material, current, temperature, the hydrology of different water levels, physics,
The information such as chemical, biological is different, and collection analysis is in the difference of different layers position water body, is environmental science, Marine Sciences etc.
The indispensable content of subject, it is widely used in the practical fields such as water area ecological environment evaluation, contamination accident investigation.
Traditional hydrophore typically hydrophore is hung on pull rope；Then, operator passes through rope by hydrophore
Transfer to the water layer of certain depth, and water sampling is carried out to the water layer of this depth by hydrophore；Followed by operator passes through
Hydrophore is lifted by rope.Current this hydrophore needs substantial amounts of manual operations, and high labor intensive is it is difficult to meet high density
That samples is actually needed；Especially under atrocious weather environment, even more it is difficult to operate.
For example, China Patent Publication No. CN202869850U, publication date on April 10th, 2013, innovation and creation entitled

The closed seawater sampler of the present invention is arranged in hull, together navigates by water with ship.
The specific work process of the closed seawater sampler of the present invention is as follows：
First, the free end of pumping conduit is transferred to the waters of specified location（The depth specified）.
Second electromagnet of each closed water sampling device is just energized, and the second iron plate 517 is adsorbed in dividing plate 53, thus will be whole
Individual hydrophore 51 adsorbs, is fixed on dividing plate.
Second, drive first piston body 3 up to move by lifting performs device 1, until first piston body is resisted against ring
On shape spacing block set 92, now, in first piston body mobile extremely sampling import and export, and sampling import and export are blocked.
3rd, open water pump, make the water in designated depth waters by the suction of pumping conduit port, and entered drinking-water pipe successively
Road, water pump, connecting pipe and water inlet enter in the inner chamber of vertical water storage cylinder 9；Then, the water in vertical water storage cylinder is gradually gone up
Unrestrained, and discharged by delivery port 95 and drainage pipeline 10.The water discharged by drainage pipeline 10 can directly be expelled back into through the country.
During water pump then gets off work, pumping conduit, water pump, in connecting pipe and vertical water storage tube inner chamber
The water that air is designated in basin is completely exhausted out（In this process because hydrophore 51 is adsorbed, consolidates by the second electromagnet
It is scheduled on dividing plate, hydrophore can be avoided in buoyancy float downward）.
4th, the first electromagnet energising of one of closed water sampling device, now its first iron plate will be in the first electricity
Move down under the suction of magnet, and drive second piston body 512 to move down, thus opening by connection guide 513
Water acquisition mouth 511；Now, the inert gas in the water storage cavity of water acquisition cylinder is discharged（It is full of inert gas in the water storage cavity of water acquisition cylinder）,
Vertically the water in water storage cylinder is by the water storage cavity automatically flowing into water acquisition cylinder.
Due to now vertically the water of water storage tube inner chamber also not with contacting external air, thus permissible during water sampling
It is prevented effectively from marine site the water sample of collection and contacting external air and is interfered, thus improving water sample analysis result to represent waters
The authenticity of environment, validity.
5th, the first electromagnet power-off of this closed water sampling device, now in the presence of compression spring, second piston
Body up moves to water acquisition mouth, and blocks water acquisition mouth；Avoid the water body in water acquisition cylinder and contacting external air.
6th, the second electromagnet power-off of this closed water sampling device, the now hydrophore 51 of this closed water sampling device
In buoyancy float downward, and sequentially pass through delivery port and the drainage pipeline of vertical water storage cylinder along current, and by drainage pipeline
Port is discharged；So far complete in the sampling process of a water sample；Marine site can be prevented effectively from so in the sampling process of water sample
The water sample of interior collection is interfered with contacting external air, thus improving water sample analysis result to represent the true of water environment
Property, validity.
7th, after completing the sampling of a water sample, water pump cuts out；And open controlled valve by the water in vertical water storage cylinder by
Water through hole and lower water tube hose are discharged.Because first piston body upper surface is provided with several closed water sampling devices, thus under
Once operated using the 3rd step only need to be returned.
