Technical Field
The invention relates to a sampling device, in particular to a device for collecting marine plastics.
Background
The plastic produced in the production process can be decomposed into tiny plastic particles to be discharged, and the tiny plastic can be mixed in the seawater. Can adopt sampling device to sample when examining the little plastics in the sea water, current sampling device utilizes the structure of gathering box and string bag, and the sea water is gathered by the input process of gathering the box, reachs the string bag by the output discharge again and gathers. The two sides of the collecting box can be fixed with the buoyancy fins through bolts or rivets, and the collecting box floats on the water surface of seawater to collect when the buoyancy of the buoyancy fins in the seawater is utilized. However, the buoyancy fins and the collecting box are fixedly connected, and the plane where the buoyancy fins are located is parallel to the axis of the collecting box, so that the buoyancy fins cannot ensure that the collecting box is driven by the buoyancy fins to float all the time, but a part of the buoyancy fins is submerged in seawater. Although the material of the buoyancy fin of the existing collection device can be replaced, so that the proper material can be conveniently replaced according to the buoyancy of the seawater, the operation is inconvenient.
Disclosure of Invention
The invention mainly aims at the problems and provides a device for collecting marine plastics. The invention aims to effectively and automatically adjust the position of the collection box on the surface of the seawater according to the disordered fluctuation of the seawater, ensure that the collection box is always positioned on the surface of the seawater and still have a part capable of sinking into the seawater.
The invention aims to be realized mainly by the following scheme: the utility model provides a gather device of marine plastics, is including the collection box that has input and output and set up the string bag at collection box output, the both sides of collection box all be provided with floating fin. The collection box is used for collecting seawater samples, and seawater with micro-plastics enters the net bag through the collection box for sampling and collection. Gather the both sides of box and all set up floating fin, floating fin not only can follow the fluctuation of sea water and float, can float for gathering the box moreover, can follow the floating of sea water and float for gathering the box for fixed buoyancy fin. Whole device has utilized the swing joint mode of floating fin and collection box, makes floating fin can float for gathering the box, and the high frequency fluctuation of rational utilization sea water self makes floating fin can float for the sea water surface as the power supply, can make the lower part of gathering the box simultaneously sink into the sea water and gather.
