Abstract

The invention relates to a seabed cruising type classification sampling device in the continental shelf area and its use method, comprising: a floating plate, several light source parts and a sleeve suspended at the center of the floating plate; the floating plate is divided into several sectors along the circumferential direction , several light source parts are respectively installed at the bottom of the fan surface, and the beams of light projected by the light source parts on several fan surfaces form several light source areas, which are respectively recorded as the first light source area, the second light source area, the third light source area...the Nth light source area There is at least one receiver connected to the arc-shaped edges of several fans through extension rods, and the receiver is electrically connected to the light source; the light source can emit light sources of different wavelengths, and the receiver receives The light source signal identifies seabed organisms; a sampling piece is arranged on the top of the floating plate, and when different seabed organisms are identified, classified sampling can be performed through the sampling piece.

Description

technical field

[0001] The invention relates to a seabed cruising type classification sampling device in the continental shelf area, in particular to a seabed cruising type classification sampling device in the continental shelf area and a using method thereof. Background technique

[0002] Studies have found that different sea creatures have different reactions to light of different wavelengths or colors. By changing the wavelength of the light source or projecting different light sources to the bottom of the sea, different marine creatures can be attracted to achieve classification and regional aggregation of marine creatures. So as to carry out classified sampling, but when the light enters the water, its intensity drops rapidly, and the color changes, referred to as attenuation. Attenuation will cause the scattering and absorption of the light source. The scattering of light is caused by particles or other small objects suspended in the water. Particles The more, the mor...
