Problems solved by technology

[0003] In the current marine environmental monitoring, microplastics in seawater are generally collected and detected, but for microplastics deposited on the seabed and mixed in seabed sediments, it is often difficult to monitor due to the difficulty in collecting suitable samples

specific Embodiment 1

[0041] Specific embodiment one: as figure 1 , figure 2 As shown, a bottom-sinking microplastic collector includes a bracket 1, a connecting rope 4, a vertical guide rod 2 arranged on the bracket, a vertical isolation cylinder 3 that moves up and down along the vertical guide rod, and a vertical isolation cylinder arranged on the vertical isolation cylinder. Stirring device 5, trigger mechanism 8, delay collection mechanism 6 and collection device 7 inside. One end of the connecting rope is connected with the support. The vertical guide rod is located below the bracket. In this embodiment, there are two vertical guide rods, and the two vertical guide rods are located on opposite sides of the vertical isolation cylinder. The vertical isolation cylinder is provided with a guide sleeve 3.1 that cooperates with the vertical guide rod, and the guide sleeve corresponds to the vertical guide rod one by one. The guide sleeve is located outside the vertical isolation cylinder, and...

Abstract

The invention discloses a bottom-sinking microplastic collector, aiming to provide a bottom-sinking microplastic collector capable of fixed-point sampling of microplastics deposited on the seabed and mixed in seabed sediments, and having convenient sampling operation. It includes a bracket, a vertical guide rod arranged on the bracket, a vertical isolation cylinder lifted and lowered along the vertical guide rod, an agitation device arranged in the vertical isolation cylinder, a trigger mechanism, a time-delay collection mechanism and a collection device. The vertical isolation cylinder is provided with a guide sleeve that cooperates with the vertical guide rod, and a guide rod limiter is provided on the vertical guide rod and below the guide sleeve. When going up, the position of the lower end of the vertical guide rod is higher than the position of the lower end of the vertical isolation cylinder.

Description

technical field [0001] The invention relates to the field of marine environment monitoring, in particular to a bottom-sinking microplastic collector. Background technique [0002] Due to its unique physical and chemical properties, plastics have become an indispensable substance in modern human life. However, plastics entering the environment have a persistent impact on the environment due to their refractory nature. Plastic waste entering the environment continues to decompose under long-term external forces such as solar radiation (photodegradation, embrittlement), wind, waves, and biological action, forming plastic particles or fragments with a particle size of <5 mm, which are microplastics. Since the particle size of microplastics is similar to that of many plankton foods, it is very easy to be swallowed by various aquatic organisms as bait, causing potential harm to them. At the same time, microplastics can stay in organisms for a long time, and transfer and enric...
