Floating anchor chain expandable settling particle trapping device

Abstract

The invention discloses a floating anchor chain expandable settling particle catching device, which comprises a floating system, an offshore warning and positioning system, an anchor chain system anda counterweight system. At least one expansion unit is connected with that anchor chain system, and the expansion unit comprises an expansion pipe arm and an expansion device. The expansion pipe arm comprises a bracket, a support ring and an annular buckle, wherein the expansion pipe arm comprises a bracket, a support ring and an annular buckle. The support comprises a hollow upright post and a support arm, wherein the upright post jacket is provided with at least one support ring, the support ring and the upright post are connected with each other through the support arm, a plurality of ringbuckles are arranged on the support ring, and the ring buckles are symmetrically arranged around the outer wall of the support ring; The expansion device is arranged on an annular buckle, and comprises a sediment capture device, an image acquisition device and a culture device, and is mainly used for sedimentation particle collection, in-situ cultivation, data acquisition and measurement, etc., and is of great significance in the research of the global marine carbon cycle and the biological pump.

Description

Technical field [0001] The invention belongs to the field of marine ecology research and relates to a floating anchor chain expandable sinking particle capture device. Background technique [0002] Currently, the commonly used floating sedimentation particle traps can only obtain a single particle sample. The disadvantage is that the equipment assembly efficiency is low, the expansion performance is poor, and other types of samples, parameters and images that match the organic carbon flux of the sedimentation particles cannot be obtained at the same time. Therefore, it cannot meet the needs of sedimentary particle samples, data parameters and scientific experiments in marine ecological research. In order to make the current floating sedimentation particle trap more convenient, have stronger expansion performance, and better meet the needs of marine ecology scientific research, we urgently need a new type that can be used for sedimentation particle capture, photography and culture...

Problems solved by technology

[0002] Currently, the commonly used floating dustfall trap can only obtain a single particle sample. The disadvantages are low equipment assembly efficiency, poor expansion performance, and the inability to simultaneously obtain other types of samples, parameters and images that match the flux of sediment organic carbon. Therefore, it cannot meet the needs of sedimentation particle samples, data parameters and scientific experiments in marine ecological research.
