A Self-releasing Bottom Sludge Collecting Device Convenient for Recycling

Abstract

The invention discloses a self-release bottom mud gathering-collecting device convenient to recycle. The device has the beneficial effects that the operation is convenient, and sediments produced within a period of time in a certain cultivation stage in a cultivation sea area can be collected according to requirements. The device comprises a balance weight base, a sediment collecting device, an upper cover plate opening-closing mechanism and a trigger release type connecting device, wherein the sediment collecting device comprises a vertical guide rod, a collecting bucket, a buoyancy block, anupper cover plate and a floating panel; the vertical guide rod is arranged on the upper surface of the balance weight base, the collecting bucket can be lifted along the vertical guide rod, the upperend of the collecting bucket is opened, the buoyancy block is arranged at the upper part of the outer side surface of the collecting bucket, the upper cover plate is used for sealing and covering theopening in the upper end of the collecting bucket, and the floating panel is arranged in the collecting bucket; the upper cover plate opening-closing mechanism comprises a vertical guide sleeve, a guide sleeve connecting component and a vertical top rod; the vertical guide sleeve is arranged in the collecting bucket, the guide sleeve connecting component is used for connecting the vertical guidesleeve with the inner side surface of the collecting bucket, and the vertical top rod is arranged on the vertical guide sleeve in a sliding manner; and the trigger release type connecting device is used for connecting the collecting bucket with the balance weight base.

Description

technical field [0001] The invention relates to a sediment collecting device, in particular to a self-releasing bottom mud collecting device which is convenient for recycling. 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 ...

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
