Description
Technical field
The present invention relates to a kind of submarine exploration sampler and its sampling methods, belong to building exploratory techniques field.
Background technique
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 usually obtains in the following manner at present: 1, anchor formula deposit soil collection
Sea-bottom deposit soil is pulled in dress in starting towboat by the way that acquisition device is fallen into marine bottom using by way of casting anchor by device
Inside is set, then takes disembarkation to be transported to laboratory and is tested, but this method easily generates dehydration disturbance, causes indoor test
As a result there is deviation with actual result；2, using in-situ test, high accuracy in-situ test equipment is directly squeezed into inside warp,
It is directly tested, but the sedimentary soil parameter of this method measurement is seldom, and instrument is costly, wants to the operation of instrument
Ask also very high.
If a publication No. is that CN105547752A discloses a kind of oceanographic survey sampler, it is characterised in that: including main frame,
The main outer frame wall surrounding is uniformly equipped with device for fetching water, and master gear is mounted on the top of main frame, pendulum is equipped on the master gear
Swing arm, pinch roller are connected at the top of swing arm, and the master gear side is engaged with the pinion that motor one drives rotation, the main frame
Inside is equipped with silt dredging device；Compared with the prior art, the advantages of the present invention are as follows: 1, it is hydraulic to soil sampler carry out pressurization make
When its pushing takes soil, the bottom surface fixation in whole device seabed, it can be ensured that sample successfully；2, in addition to carry out soil sampling it
Outside, moreover it is possible to carry out water sampling again, function is increased；3, mud guard the operation is stable of soil sampler passes through spring automatic rebounding, gear
Firmly soil sampler.
For another example a publication No. is to adopt as patent announcement CN203452779U discloses a kind of fluid pressure type sea-bottom deposit soil
Acquisition means, including protection frame body, suspension hook and wirerope, the suspension hook are arranged in fender bracket body top, and wirerope is connected to
Above suspension hook, characterized in that the protection frame body is integrally cylindrical, and surrounding is welded with for protecting in frame body to protect
The round steel of portion's equipment, the hydraulic cylinder, which is equipped with, is divided into the first pumping chamber and the second pumping chamber, the first pumping chamber and the second pumping chamber
Centre is separated with piston, and hydraulic cylinder lower section is sealedly connected with soil sampler using screw one.It is simple with structure, cheap, operation
The advantages that aspect, has a vast market foreground.
The technical field of patent publication No. CN105547752A and CN203452779U the application is identical, and the technology of solution is asked
Inscribe identical, technical characteristic disclosed in CN105547752A is most, can be used as the immediate prior art of the application, but it has
Disadvantage is as follows: soil sample is detached from using flapper 13 soil sampler in order to prevent in sampling process, and this design method makes
It will appear inc situation with flapper 13 in the process, while the sampling structure of CN105547752A is excessively complicated, simultaneously
The decline resistance of the sampler is very big.Therefore, the present invention proposes another technical solution to provide a kind of taking for reliable performance
Sample device makes current urgent problem.
