Full sea depth small self-floating type straight-through impact sampling device

Abstract

The invention provides a full sea depth small self-floating type straight-through impact sampling device, which includes an upper release self-floating mechanism and a lower load rejection counterweight mechanism. The release self-floating mechanism includes a flat cylindrical buoyancy block, the circumference of which is uniformly provided with at least two sleeves extending downward vertically. A fixation seat is fixedly connected to a place below the center of the buoyancy block, the part below the fixation seat is fixedly connected to at least one clamping sleeve, and a sampling tube is connected below the clamping sleeve. A buffer spring is arranged between the sampling tube and the clamping sleeve top wall. The load rejection counterweight mechanism comprises a load rejection counterweight block, and a guide stabilizing column is arranged above the load rejection counterweight block. And a mechanical release mechanism is disposed below the center of the fixation seat. The impact sampling device provided by the invention solves the problems of difficult carrying, complex structure, expensive cost and the like in existing seafloor samplers. After sampling, the load rejection counterweight block floats upward independently, additional power and stranded cable are not needed, 2-3 people can finish the all launching and retrieval process, and the device has the characteristics of simple and reliable structure, and convenient maintenance.

Description

technical field [0001] The invention belongs to the technical field of deep-sea resource exploration and development equipment, and in particular relates to a full-sea small self-floating straight-through impact sampling device. Background technique [0002] The ocean accounts for 70.78% of the earth's total area, and the depths of the ocean are widely covered with a layer of mysterious but very research-worthy seabed sediments. Seabed sediments are very important for understanding the changes in the earth's environment, revealing the inner connection between the earth's environmental systems and predicting the future. Long-term climate change is of great significance. Sampling and in-depth research on seabed sediments can enable human beings to obtain very important scientific value in the fields of marine scientific research, marine environment research, marine resource exploration, marine engineering exploration, etc. It is of great strategic importance for human beings t...
