Pre-adding self-upward-floating sediment collection body

Abstract

The invention discloses a pre-adding self-upward-floating sediment collection body, and aims to provide the pre-adding self-upward-floating sediment collection body which not only is easy to operate but also can collect sediments in a breeding sea area after a certain breeding stage in a period of time according to needs. The pre-adding self-upward-floating sediment collection body includes a balance weight base, a sediment collection device, a buoyancy device, a port sealing device and a trigger release type connecting device; the sediment collection device includes a collecting barrel and afloating flat plate arranged in the collecting barrel, the bottom surface of the collecting barrel is provided with a vertical supporting rod for supporting the collecting barrel, and the collecting barrel is supported on the upper surface of the balance weight base through the vertical supporting rod; the buoyancy device includes a buoyancy cylinder sleevedly arranged on the collecting barrel anda floating block arranged on the outer side surface of the buoyancy cylinder; the port sealing device includes a head plug column arranged in the collecting barrel and located below an upper barrel body; the trigger release type connecting device is used for connecting the buoyancy cylinder and the balance weight base.

Description

technical field [0001] The invention relates to a sediment collector, in particular to a pre-dropped self-floating sediment collector. Background technique [0002] With the development of society and economy, the scale of coastal purse-seine farming continues to expand, and ecological and environmental issues have attracted attention; this farming method inevitably brings a lot of pollution, such as residual bait, fish excrement, etc., and a large part of these wastes are deposited on the seabed , the impact on the marine bottom environment, the bottom environment presents a eutrophication trend; therefore, it is very important to collect the seabed sediments in artificially cultivated sea areas, and then analyze and study the marine bottom environment in aquaculture sea areas. [0003] The current collection of seabed sediments in artificially cultured sea areas is usually collected by using mud pickers, but the current mud pickers to collect seabed sediments are not only ...

AI Technical Summary

Problems solved by technology

[0003] The current collection of seabed sediments in artificially cultured sea areas is usually collected by using mud pickers, but the current mud pickers to collect seabed sediments are not only inconvenient to operate, but also can only collect bottom mud in general, and cannot be collected in certain cultured sea areas. Sediments over time after a culture period
