A deep-sea sampling anti-mis-trigger shock absorber

Abstract

The invention relates to a deep sea sampling vibration absorber capable of preventing false triggering. The deep sea sampling vibration absorber is arranged between a supporting ballast device of a sampler and a sampling detector, and comprises a shaft extension piston rod and a cylinder block, wherein the head part of the shaft extension piston rod is connected with the supporting ballast device; the tail part of the cylinder block is connected with the sampling detector; the other end of the shaft extension piston rod is connected with a piston arranged inside the cylinder block; a check valve is arranged at the bottom of the cylinder block; a damping hole is formed in the side, close to the bottom, of the cylinder block. The deep sea sampling vibration absorber disclosed by the invention has the benefits that the vibration absorber can effectively relieve asynchronous vibration when the supporting ballast device of the sampler and the sampling detector are resonated, prevents the joint coupling switch from false triggering, improves the sampling reliability, and further improves the sampling efficiency.

Description

technical field [0001] The invention relates to the field of marine environment detection and sampling instruments, in particular to a deep-sea sampling anti-false trigger damper. Background technique [0002] At present, most deep-sea samplers are sampled by mechanical triggering. The principle is: when the sampler touches the bottom, the sampling detection device touches the bottom and stops, the supporting ballast device is still going down, the connection and the coupling coupling switch between them receive their relative close displacement, and the sampling is opened when the relative close displacement reaches the set distance The switch, through a series of associated mechanical actions, completes the collection of seabed mud samples and water samples. A steel cable is suspended from the upper part of the sampler, and the winch on the ship lowers the steel cable, and the sampler is then lowered to several thousand meters of seabed. This method is basically adopted ...

If this happens, the sampling efficiency will be very low, and even the investigation task cannot be completed.

It takes a huge amount of money and a high time cost for experts and professors organized by the state to conduct ocean expeditions or expeditions to the North and South Poles. The overall cost per working hour is millions of dollars.
