Description
Technical field
The present invention relates to sediment deposit sampling equipment, and in particular to one kind can throw load-type deep-sea gravity column and sink
Product thing sampler, the acquisition for deep seafloor substrate column shaped deposit sample.
Background technology
Carry out deep-sea Oceanic Sedimentary Environments, seabed sediment acoustics, marine engineering geology, submarine geological hazard identification with
Evaluation etc. research when, only obtain a number of bottom sediment original state sample, could carry out direct grain size of sediment,
The analysis of structure, composition etc. and the measure in age, so as to obtain corresponding geological information.Therefore, column shaped deposit undisturbed
Acquisition be the association area research such as Marine Geology important prerequisite and basis.
The method for obtaining Submarine core sediment has a lot, for example, it is currently used mainly have gravity coring apparatus and shake
Piston sampler.Notification number CN2360587Y Chinese patent discloses a kind of " long core gravity pison sampler " technology,
By caused impulse force in equipment self-weight and dropping process, make to be sampled in probe tube drilling underwater sediment(s)；Notification number
CN100334436C Chinese patent discloses a kind of " single tube sediment sampler of non-boundary disturbance " technology, is primarily adapted for use in
The deposit sampling of shallow water area；Notification number CN101592562A Chinese patent discloses a kind of " Seafloor sediment sampling
Device ", by the way of gravity and vibration combine, the sampling of bottom sediment is completed, suitable for the acquisition of hardground deposit.
Gravity coring apparatus is a kind of sampler simple in construction, easy to operate, sampling quality is high, is widely used in
In the sampling of bottom sediment.The sample quality and the counterweight of sampler that gravity coring apparatus obtains are closely related, and one is well matched
Again bigger, the sample length of acquisition is bigger, quality is better.As far-reaching sea, traditional gravity are gradually moved towards in present ocean scientific research
Coring apparatus comes up against a series of problems in the use that deep-sea, the especially depth of water are more than 4000 meters of marine sites.Carry out seabed cylindrical
When deposit samples, what winch was born is that the quality of wirerope weight, sampler and counterweight, sampler are transferred to from bottom sediment
When be subject to frictional force, take sediment quality sum.Deep-sea column is being carried out using Conventional gravity column shaped deposit sampler
When deposit samples, because depth is big, discharging wirerope length accordingly increases, and the wirerope weight that geological winch is born on ship significantly increases
Greatly, so in the case where winch weight capacity is certain, it is impossible to obtain the deposit of high quality by increasing counterweight simply
Sample.When carrying out the sampling of deep-sea column shaped deposit using the poor boat-carrying geological winch of weight capacity, due to Conventional gravity post
The lead load that can be attached on shape sampler is smaller so that sampling effect is poor, or even can not get sediment sample, this limitation
Application of the Conventional gravity coring apparatus in the geological sampling of deep-sea.And if can be before sampler recovery (from seabed
Before sampler being transferred in deposit) jettisoning lead load, then it can substantially reduce geological winch when sampler is transferred to from seabed and hold
The pulling force received, influence of the sampler lead load to winch load-bearing that make that we must not contemplate allow us within the specific limits
Increase lead load, improve sampling quality.
Therefore, determined according to the ability to bear of research vessel winch, sampling requirement, required counterweight etc. from bottom sediment
Contained lead load whether is abandoned before transfering to sampler, so as to reduce the pulling force suffered by boat-carrying winch wirerope, increases gravity column
Deposit sampler meets that halmeic deposit samples demand in the scope of application and sampling effect at deep-sea, propose it is a kind of it is new can
Load-type gravity column shaped deposit sampler is thrown, is technical problem urgently to be resolved hurrily.
