Simple paleomagnetic study sampling device for ocean sediments

Abstract

The invention discloses a simple paleomagnetic study sampling device for ocean sediments. The simple paleomagnetic study sampling device comprises a rack and a control device, wherein the rack comprises two support plates, a beam and two bases; the two support plates are connected with the two bases respectively; the beam is connected with the two support plate in a longitudinal sliding manner; a drive device is arranged at the upper part of the beam and is connected with the control device; a fixed hole and a locking device are arranged at the bottom of each support plate separately; each locking device is connected with the control device; each locking device is connected with the corresponding fixed hole; each locking device comprises a small air cylinder and a locking rod; and locking holes corresponding to the locking rod are formed in two ends of the beam. Through design and interaction of the locking devices and the locking holes, the stability of the beam in the extraction process of a sample is ensured and the extraction accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of clay extraction, in particular to a simple sample dividing device for paleomagnetic research of marine sediments. Background technique [0002] Archeology is a very cumbersome work, which requires very high accuracy. Generally, it is to ingest and study the items left over from history. Generally, archaeological items are distributed on the surface or deep in the ocean, and drilled from the seabed The retrieved columnar core samples need to be divided into two half cylinders along the diameter, and then the seabed sediments are divided into samples and loaded into the sample box for magnetic parameter measurement. Generally, what needs to be studied is that the seabed sediment is mainly silt, and its main component is clay. The sedimentation process is very slow and undergoes complex biological and chemical actions. Due to its very low deposition rate, the sedimentation process is affected by the geomagne...

Problems solved by technology

Generally, what needs to be studied is that the seabed sediment is mainly silt, and its main component is clay. The sedimentation process is very slow and undergoes complex biological and chemical actions. Due to its very low deposition rate, the sedimentation process is affected by the geomagnetic field. The magnetic poles drift with time, and even reverse. The sediments at different times record the strength and direction of the geomagnetic field at the corresponding time. Through the measurement of magnetic parameters, the change of magnetic declination with time can be determined, and the reversal of the geomagnetic field can be inferred. The geological age and paleoclimate changes, so the sample extraction process needs to be very careful, and it needs to be extracted very accurately. In the prior art, manual measurement and extraction are generally used. Such an operation There are many deficiencies, such as manual observation with the naked eye, there will be certain errors, manual measurement and sampling may lead to incomplete product extraction, which will affect the later experimental data, and the whole process is very labor-intensive. The invention proposes a brand-new solution to the above problems
