Description
Technical field
The invention belongs to benthonic sampling equipment field, ocean, deep-sea, sea, a kind of deep-sea based on ROV platform
End grab sample device.
Background technology
Produce and in scientific research and testing at ROV (unmanned remotely controlled submersible vehicle) actual ocean scientific investigation, subsea construction operations, according to
The difference of job task, is required to use some can bear the high performance tools of deep sea pressure.At present, it is possible to bear deep-sea
The high performance tools of pressure can be roughly classified into two classes: a class has been conventional underwater performance task, can match some more
Standard, general power tool.These instruments the most all have an interface of standard, commercially available also can develop voluntarily.Another kind of it is
Complete the sample collecting of some specific job tasks, such as various uses, due to sampling object vary, characteristic different,
So mostly needing the corresponding sampling tool of special development, and need the expertise of related discipline, thus there is higher difficulty
Degree.Such sampling tool used at present is such as: cleaning brush, abrasive cutoff saw, impact brill, clipper, clamper, impact spanner, punching
Wash rifle etc. and be substantially Engineering work, the most few for the instrument of sample；Meanwhile, it is currently used for submarine sampling
General sampler such as: box take mud, TV grab bucket etc., due to the mechanical connection location existed between ROV, circuit, oil circuit
The problems such as docking, cause cannot using on ROV, and additionally its bigger volume and deadweight largely limit existing equipment
Necessity of transformation.The needs of substantial amounts of bottom sample are obtained for satisfied use ROV, little in the urgent need to a kind of new structure of exploitation
It is convenient to dock with ROV ingeniously, can meet the sampler of deep ocean work simultaneously.
