[0003] The invention patent with the notification number of CN 108608476 A discloses a sampling pipe splitter, CN210757976U discloses a sediment extraction pipe cutting device, and CN 109682633 B discloses an automatic multi-directional adjustable marine sediment core dissection Method, CN106378821B discloses a columnar sediment cutting equipment and method, these are all devices for dissecting columnar sediment sampling tubes, but the emphasis is slightly different, and the requirements for the working environment are relatively high, generally used for indoor columnar sediment Sediment dissection
[0004] In addition to being equipped with columnar sediment cutting equipment similar to that described in CN106378821B on a very small number of large-scale scientific research ships, the columnar sediment sampling tube dissecting work on the spot mainly relies on manual hand-held electric saws to operate at present, resulting in cutting the sampling tube. The sediment in the tube produces different degrees of disturbance and influence, which directly affects the subsequent analysis and test results

Abstract

The invention relates to the technical field of ocean sampling devices, in particular to a cutting device and a cutting method of a columnar sediment sampling pipe. The cutting device comprises a sampling pipe fixing mechanism and a sampling pipe cutting mechanism; the sampling pipe fixing mechanism comprises a sample loading table, a groove, a limiting rod and a fixing bracket; the groove is formed in the upper surface of the sample loading table and is used for placing the sampling pipe; the limiting rod is arranged on one side of the sample loading table and is used for fixing the front-back position of the sampling pipe; the fixing bracket is arranged at the upper end of the sample loading table and is used for fixing the up-down position of the sampling pipe; the limiting rod comprises a thread propulsion rod; one end of the thread propulsion rod is connected with a fixator through a rotary hole; and and a hand wheel capable of enabling the fixator to move back and forth along thesample loading table without rotating is mounted at the other end of the thread propulsion rod. The cutting device is convenient to carry and low in cost and operating environment requirement, firmlyfixes the sampling pipe, can precisely cut the sampling pipe with certain proportion according to the requirement without damaging an earth pillar in the sampling pipe and avoids influence to the testing result.

Description

technical field [0001] The invention relates to the technical field of marine sampling devices, in particular to a cutting device and a cutting method for a columnar sediment sampling pipe. Background technique [0002] When conducting research on marine sedimentary environment, acoustics of seabed sediments, marine engineering geology, identification and evaluation of seabed geological hazards, etc., only a certain number of undisturbed samples of seabed sediments can be obtained to conduct direct sediment particle size, structure, composition, etc. Analysis and age determination, in order to obtain the corresponding geological information. Therefore, seabed columnar sediment samples are an important prerequisite and material basis for research in marine geology and other related fields. After obtaining the columnar sediment samples, if the physical properties, sedimentary structure, color, plasticity and other tests are to be tested, the sampling tube is generally cut ope...
