Description
Technical field
The invention belongs to marine environment engineering field, more particularly to a kind of oceanographic survey sampler and its sampling method.
Background technology
The sea joined together on the earth and total waters in ocean, including seawater, the material for dissolving and suspending in water, seabed sink
Product thing, and the biology in life Yu Haiyang.Therefore marine environment is an extremely complex system.The mankind do not live in sea
On ocean, but ocean be human consumption and production indispensable matter and energy source.With the hair of Science and Technology
Exhibition, the scale of human development marine resources is increasing, and to the degree of dependence more and more higher of ocean, while ocean is to the shadow of the mankind
Sound also increasingly increases.Scale with human development marine resources expands day by day, and ocean is influenceed and dirt by mankind's activity
Dye.
The physical-property parameter of deposit on marine-bottom surface, such as deposit natural moisture content and natural density, for Submarine Pipeline
Road, cable etc. are directly seated the design of the engineering structure of submarine surface and construction is indispensable important parameter.
The physical performance index of these deposits generally obtains in the following manner at present：1st, anchor formula deposit soil collection
Device, harvester is fallen into marine bottom by using the form cast anchor, restart towboat and sea-bottom deposit soil is pulled in into dress
Inside is put, then takes disembarkation to be transported to laboratory and is tested, but this method easily produces dehydration disturbance, causes indoor test
As a result there is deviation with actual result；2nd, using in-situ test, high accuracy in-situ tester is directly squeezed into inside warp,
Directly tested, but the sedimentary soil parameter of this method measurement is seldom, and instrument is costly, the operation to instrument will
Ask also very high.
As patent announcement CN203452779U discloses a kind of fluid pressure type sea-bottom deposit soil collecting device, including protection
Frame body, suspension hook and steel wire rope, the suspension hook are arranged on fender bracket body top, and steel wire rope is connected to above suspension hook, its feature
It is that the protection frame body is integrally cylindrical, and surrounding is welded with for protecting the round steel of fender bracket body interior equipment, institute
State hydraulic cylinder and be provided with and be divided into the first pumping chamber and the second pumping chamber, piston, liquid are separated among the first pumping chamber and the second pumping chamber
Below cylinder pressure soil sampler is sealedly connected with using screw one.The utility model has simple in construction, cheap, operating aspect etc.
Advantage, there are wide market prospects.
And for example CN203669088U discloses a kind of silt collecting box with liftable mud shuttle, belongs to city inspection shaft silt
Mud cleaning equipment technical field.Technical scheme is：Mud shuttle is located in mud shuttle movement frame, and is slided and connected with mud shuttle movement frame
Connect, the mud shuttle cover plate being engaged with mud shuttle is additionally provided with mud shuttle movement frame, mud shuttle movement frame upper end is collected with mud
Case upper end is hinged, and mud shuttle movement frame lower end is hinged by mud shuttle rotational fuel tank and silt collecting box lower end, and dumping oil cylinder is set
In silt collecting box, one end is hinged with silt collecting box casing, and the other end is hinged with silt collecting box bottom plate.Pass through mud shuttle
Motion in mud shuttle movement frame, can make desilting processing efficient, by the rotation of mud shuttle movement frame, expand inside inspection shaft
Job area.
Patent publication No. CN203452779U is identical with the technical field of the application, and the technical problem of solution is identical, open
Technical characteristic it is most, the immediate prior art of the application can be used as, but its disadvantage is as follows：1st, in hydraulic pressure to fetching earth
When device carries out pressurization and pushes it to fetch earth, because whole device does not have and the bottom surface fixation in seabed, often fetch earth
Whole device can be propped up in device insertion soil, the soil sample that can so cause to obtain is seldom or samples failure；2nd, function is single,
It can only be fetched earth, it is impossible to carry out water sampling again；3rd, the mud guard job insecurity of soil sampler, keeps off after the completion of soil sampler fetches earth
Native piece is sticked above by mud and can not accurately fallen, if the soil sample leakiness in soil sampler, often in removal process
Middle soil sample can depart from out of soil sampler, cause sampling to fail.Therefore it provides a kind of sampler of dependable performance makes to be badly in need of solution at present
Certainly the problem of.
