Sediment capturing equipment for marine environment monitoring

Abstract

The invention provides sediment capturing equipment for marine environment monitoring. The equipment comprises an equipment body; a sealing piece is opened and closed at one end of the bottom of the equipment body; a reset spring is mounted between the sealing piece and the lower surface of the equipment body; a capturing part is arranged in the equipment body; a floating part is arranged above the capturing part; the sealing piece is used for sealing the bottom of the equipment conveniently; when sediments need to be captured, a guide rod continuously swings up and down; two hook plates whichincline leftwards are convenient to hook the sediments and then throw the sediments into the lower end of an intercepting plate and an intercepting net; when the guide rod swings downwards, the sealing piece and the guide rod are parallel to each other and do not seal the bottom of the equipment, so that seawater inrush into the equipment; when the guide rod swings upwards, the sealing piece seals the bottom of the equipment, so that the seawater inrush amount is conveniently reduced, and the seawater can be prevented from continuously inrush into the equipment while sediments are captured.

Description

technical field [0001] The invention relates to the technical field of marine environment, in particular to a sediment capture device for marine environment monitoring. Background technique [0002] The marine environment refers to the total waters of the vast and continuous seas and oceans on the earth, including seawater, substances dissolved and suspended in seawater, seabed sediments and marine organisms. It is the cradle of life and the treasure house of human resources. The scale is expanding day by day, and the marine environment has been affected and polluted by human activities. Marine sediment refers to the general term for the seabed sediments formed by various marine depositions. The substances deposited on the seabed with seawater as the medium, because these processes are often not isolated Therefore, the sediment can be regarded as a geological body produced by comprehensive action; [0003] During the capture process of the existing marine environment sedime...

AI Technical Summary

Problems solved by technology

[0003] During the capture process of the existing marine environment sediment capture equipment, when the sediment enters the equipment body, seawater also pours into the equipment at the same time, which easily makes the equipment unstable on the seabed and prone to rollover, and seawater continuously pours into the equipment It is easy to occupy the internal space of the equipment, and it is not convenient to capture sediments. Therefore, further research is needed on the basis of marine environment sediment capture equipment to provide a sediment capture equipment for marine environment monitoring.
