Seabed float sludge detecting and sampling device and sampling method thereof

Abstract

The invention discloses a seabed float sludge detecting and sampling device and a sampling method thereof. The device comprises a shell part, a drainage part and a sampling part, when seabed float sludge needs to be collected, the device is used and placed in the sea, and the device sinks to the seabed under the action of gravity. The supporting frame enables the equipment to be kept upright, the supporting block sinks into float sludge, and the equipment is kept horizontal under the action of gravity. The gravity block presses the fixing nail to move downwards to fix the equipment in the float sludge, and a magnet on the lower portion of the lowering mechanism is placed in a sleeve in the middle of the upper shell. The air storage tank exhausts air into the shell main body, seawater flows out of a hole of the drainage switch sleeve, and after the seawater is completely drained, the air storage tank stops exhausting air, so that the shell main body is in a water-free state. The electromagnet pushes the sampling shell to move downwards to a designated position, and the sampling door turns over and rotates, so that the float sludge is conveyed into the sampling tank. After sampling is completed, the equipment recovers to the original state, the moving cylinder is taken out, the state of the float sludge in the sampling tank is observed, the sampling tank is taken out, and the sampled float sludge is taken out for observation.

Description

technical field [0001] The invention relates to the technical field of floating mud sampling, in particular to a seabed floating mud detection sampling device and a sampling method thereof. Background technique [0002] At present, the sea area survey and sampling are mainly the deposited bottom or seawater 0.5-1m away from the bottom, but there is no sampling research device for the floating mud and floating mud above the bottom, and this part is very important for the marine environment, marine organisms, seawater quality, ocean The construction of pasture all has bigger influence, and my country's sea area is vast, is powerful for the sampling research of seafloor floating mud and for the management of my country's ocean, therefore, the main purpose of the present invention is to collect more than the seabed stable sediment in sections to the clean seawater part It is convenient to observe the thickness of floating mud and detect its material composition.
