Scoop Seabed Surface Sampler

Abstract

The invention belongs to a shovel type seabed surface layer sampler of a seabed sampling device for sampling a seabed surface layer substrate. With adoption of the scheme that storage cavities in theback part of sampling cabins are mounted in sample cabin sleeves in a sleeving manner and the sampling cabins are detachably connected to the sample cabin sleeves; the sample cabin sleeves are hingedto a bracket; the at least three sampling cabins are arranged around the axis of the bracket; a baffle plate of a sampling port is fixedly connected to the bracket, is matched with the sampling port of each sampling cabin, and upwarps upward; a release heavy punch is mounted in a release guide tube in a sleeving manner; a release hook is hinged to the release guide tube; the upper part of the release heavy punch is connected to a release recovery rope, the lower part is connected to a sample recovery rope, and the other end of the sample recovery rope is connected to a material taking port; one end of a switch rope is connected to each sample cabin or each sample sleeve while the other end is matched with the release hook; and the upper part of the release hook is matched with the upper part of the release heavy punch and the lower part of the release hook is matched with the side face of the release heavy punch, the technical problems that the close port of an existing shovel type seabed surface layer sampler is not closed tightly, samples are lost and the hook fails are solved.

Description

technical field [0001] The invention belongs to a seabed sampling device, in particular to a shovel type seabed surface sampler. Background technique [0002] When sampling the seabed surface, clam samplers and box samplers are commonly used. In the sampling work of the existing marine surface and bottom, DDC series clam-type mud extractors and DDC series box-type samplers are widely used. Their closing ports are at the lower end of the sampler. Gravel or other particles are caught, resulting in lax closure of the closure, and particles with smaller particle sizes will be lost during the recovery process; the release device of the existing clam sampler is that the other end of the hook is equipped with a counterweight, and a recovery rope is used in the middle Connection, the hook is hung on the iron chain of the sampler. When the sampler reaches the bottom of the sea, the hook is not stressed, and the hook falls off under the action of the counterweight to complete the rel...

AI Technical Summary

Problems solved by technology

[0003] The present invention solves the technical problems of lax closure of the existing seabed surface sampler, sampling loss, and failure of the hook, and provides a shovel-type seabed surface sampler that is not easy to lose samples in the recovery process, releases, samples and recovers reliably.
