A collection device for ecological environment monitoring in aquaculture sea area

Abstract

The invention discloses a collecting device for monitoring ecological environment in aquaculture area, and aims at providing a collecting device which is not only convenient to operate, but also can collect sediments in aquaculture area within a certain time after a certain aquaculture stage as required, and is used for monitoring ecological environment. The collecting device comprises a counterweight base, a sediment collection device, a sealing mechanism, a connecting device and a self-releasing locking device, wherein the sediment collection device comprises a collection barrel positioned on an upper-end opening above the counterweight base, a buoyancy block arranged on the upper part of the outer side surface of the collection barrel, and a floating panel arranged in the collection barrel; the sealing mechanism is used for sealing the upper-end opening of the collection barrel; the connecting device comprises a wire spool and a connecting rope, the wire spool is rotationally arranged on the bottom surface of the collection barrel through a horizontal shaft rod, the connecting rope is wound on the wire spool, the wire spool is positioned below the collection barrel, one end of the connecting rope is connected with the wire spool, and the other end of the connecting rope is connected with the counterweight base; and the self-releasing locking device is used for locking the wire spool.

Description

technical field [0001] The invention relates to a sediment collection device, in particular to a collection device for ecological environment monitoring in aquaculture sea areas. 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 picke...

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
