Description
Technical field
The invention belongs to marine environment engineering field, particularly a kind of oceanographic survey sampler and sampling method thereof.
Background technology
Total waters in the sea that the earth joins together and ocean, the material, the marine bottom sediment that comprise seawater, dissolve and suspend in water, and move in the biology in ocean.Therefore marine environment is a very complicated system.The mankind do not live on ocean, but ocean be human consumption and produce the source of indispensable matter and energy.Along with the development of Science and Technology, the scale of human development ocean resources is increasing, more and more higher to the degree of dependence of ocean, and the impact of ocean on the mankind simultaneously also increases day by day.Along with the scale expanding day of human development ocean resources, ocean has been subject to impact and the pollution of mankind's activity.
The physical-property parameter of deposit on marine-bottom surface, as sediment natural moisture content and natural density, the design and the construction that submarine pipeline, cable etc. are directly seated to the engineering structure of submarine surface are indispensable important parameters.
These sedimental physical performance indexs obtain usually in the following manner at present: 1, anchor formula sediment soil collecting device, by utilizing the form of casting anchor, harvester is fallen into marine bottom, at startup towboat, thalassogenic sedimentation soil drawn-back device is inner, get disembarkation to be again transported to laboratory and to test, but this method very easily produces dehydration disturbance, indoor test result and actual result is caused to occur deviation; 2, adopt in-situ test, high accuracy in-situ testing tool is directly squeezed into warp inside, directly tests, but the sedimentary soil parameter that this method is measured is little, and instrument is costly, also very high to the operation requirements of instrument.
As patent announcement CN203452779U discloses a kind of fluid pressure type thalassogenic sedimentation soil collecting device; comprise fender bracket main body; suspension hook and wire rope; described suspension hook is arranged on fender bracket body top; wire rope is connected to above suspension hook; it is characterized in that; described fender bracket entire body is cylindric; surrounding is welded with the round steel for protecting fender bracket body interior equipment; described hydraulic cylinder is provided with and is divided into the first pumping chamber and the second pumping chamber; be separated with piston in the middle of first pumping chamber and the second pumping chamber, below hydraulic cylinder, utilize screw one to be sealedly connected with soil sample barrel.It is simple that the utility model has structure, and cheap, the advantages such as operating aspect, have wide market outlook.
And for example CN203669088U discloses a kind of silt collecting box with liftable mud shuttle, belongs to city inspection shaft mud cleaning equipment technical field.Technical scheme is: mud shuttle (7) is located in mud shuttle movement frame (11), and be slidably connected with mud shuttle movement frame (11), the mud shuttle cover plate (9) matched with mud shuttle (7) is also provided with in mud shuttle movement frame (11), mud shuttle movement frame (11) upper end and silt collecting box (1) upper end thereof, mud shuttle movement frame (11) lower end is hinged by mud shuttle rotational fuel tank (5) and silt collecting box (1) lower end, dumping oil cylinder (2) is located in silt collecting box (1), one end and silt collecting box (1) casing hinged, the other end and silt collecting box base plate (4) hinged.By the motion of mud shuttle in mud shuttle movement frame, desilting processing efficient can be made, by the rotation of mud shuttle movement frame, expand the scope of work of inspection shaft inside.
Patent publication No. CN203452779U is identical with the technical field of the application, the technical matters solved is identical, disclosed technical characteristic is maximum, can be used as the immediate prior art of the application, but its shortcoming had is as follows: 1, when hydraulic pressure to pressurize to soil sample barrel and makes it press down to fetch earth, due to whole device not and the bottom surface fixation in seabed, often soil sample barrel inserts in earth and whole device can be propped up, and the soil sample that obtains can be caused so little or sample unsuccessfully; 2, function singleness, can only fetch earth, and can not carry out water sampling again; 3, the mud guard job insecurity of soil sample barrel, be subject to mud and stick above at the soil sample barrel backstop soil sheet that fetched earth and can not accurately fall, if the soil sample leakiness in soil sample barrel, often in removal process, soil sample can depart from soil sample barrel, causes sampling unsuccessfully.Therefore, a kind of sampler of dependable performance is provided to make current urgent problem.
