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 sink-to-bottom type microplastic collector, and aims to provide a sink-to-bottom type microplastic collector that can perform fixed-point sampling on microplastics depositedon the sea floor and mixed in the sea bottom sediment, and has convenient sampling operation. The sink-to-bottom type microplastic collector comprises a support, a vertical guide rod arranged on the support, a vertical isolation cylinder lifting along the vertical guide rod, an agitation device disposed in the vertical isolation cylinder, a trigger mechanism, a time delay collection mechanism anda collection device, wherein a guide sleeve matching with the vertical guide rod is provided on the vertical isolation cylinder, a guide rod limit block is provided on the vertical guide rod and located below the guide sleeve, and when the guide rod limit block supports against the lower end surface of the guide sleeve, 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...
