Problems solved by technology

For example, the publication number is CN107314908A, and the patent name is "a detachable sediment sampling device", which includes a handle assembly, a lock assembly, a load box, a sampling box, a connecting rod, and two grabs. The opening and closing action of the bucket grabs the sediment on the surface of the seabed. Grab-type collectors with a two-claw structure are generally inconvenient to operate the grab, it is difficult to close the two grabs smoothly on the seabed, and the samples in the grab are easy to Slippage and other shortcomings, the sampling efficiency is low, and the sampling process takes a lot of time to collect samples that meet the requirements
[0004] In addition, the two grabs in the existing grab-type collector are articulated and closed, so that the collected samples are usually stirred and mixed, and various substances in the collected sediment are mixed and stirred together, which cannot The distribution state of each object in the sample is well preserved, which affects the subsequent accurate research and analysis, especially not suitable for deep sample collection and analysis in places where the seabed mud layer is relatively thick

Abstract

The invention discloses an automatic sampling device for seabed sediments comprising an outer cylinder, a sampling inner cylinder, a stepping driving mechanism and a guide assembly; the stepping driving mechanism is installed on an upper installation plate at the upper end of the outer cylinder, the output end of the stepping driving mechanism is connected with the top of the sampling inner cylinder, the lower end of a guide shaft in the guide assembly is connected with a guide connecting plate at the top of the sampling inner cylinder, the lower end surface of the outer cylinder is further provided with a sliding sample-holding base plate capable of horizontally moving, the sliding sample-holding base plate is connected with a sample-holding driving mechanism, the sample-holding driving mechanism comprises an installation disc, a rack, a driving gear and a driving motor, the driving motor is fixed on the installation disc through an installation bracket, the driving gear is arranged at the output shaft end of the driving motor and is meshed with the rack arranged on the sliding sample-holding base plate, the top surface of the sliding sample-holding base plate is in sliding contact with the lower end surface of the sampling inner cylinder, the bottom surface of the sliding sample-holding base plate is in sliding contact with the upper surface of the installation disc, and theinstallation disc is fixed on the lower end surface of the outer cylinder through a connecting column.

Description

technical field [0001] The invention relates to the technical field of marine sampling, in particular to an automatic sampling device for seabed sediment. Background technique [0002] In the course of ocean research, it is often necessary to collect sediments from the surface layer of the seafloor. With the improvement of marine resource research and investigation requirements, especially for the study of seabed environment changes in offshore aquaculture areas, it is necessary to collect more and more accurate sediments on the seabed surface, and it is necessary to keep the original state of the collected samples as much as possible to ensure the collection of seabed surface. Sediments are not affected by disturbances during collection. [0003] In the prior art, a grab-type collector is usually used to sample the sediment on the seabed surface. For example, the publication number is CN107314908A, and the patent name is "a detachable sediment sampling device", which incl...
