Air holding sampler for lower layer seabed sediment

摘要: The utility model belongs to a sampling device. Particularly sampler for lower layer seabed sediments. comprises sleeve pipe, wherein lining pipe capable of sliding along the inner wall is arranged in pipe. upper end can be connected with release device; provided cutter head; middle part two sealed ball valve at intervals; switch and hydraulic drive Since takes device driven mode, closing valves has high degree automatization reliability. In addition, since least one locking on samples piecewise preserved; lamellar structure sediments better known.
