Problems solved by technology

[0003] At present, microplastic sample collection devices in marine water bodies are mostly aimed at water bodies below 0.5m, generally in the form of trawling nets, and simple mesh bags are used to collect them, but this method depends on the voyage of the ship, and the structure of the mesh bag is single, so it can only collect particles larger than The particulate matter in the pore size of the mesh bag cannot be classified and screened, so that the staff cannot detect the content of microplastic particles in the water in time, and the collected particulate matter needs to be further separated, and there is currently no suitable device for particulate matter. Synchronous separation of substances results in low separation efficiency and is easily affected by other solid suspended solids or phytoplankton in seawater, making it difficult to collect and separate microplastics in the later stage, which affects the final quantitative results of microplastic content
During the process, it is easy to have the problem that other suspended solids in seawater are mixed with microplastics

[0043] A device for collecting microplastics in marine microsurface water, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, it includes a rotating wheel 1, a cable 2, a bracket 3, a motor 4, a fixed block 5, a rotating bar 6, a first fixed rod 7, a slide bar 8, a first floating block 9, a floating collection frame 10, a wedge bar 101, the second floating block 11, guide plate 111, flow meter 112, filter mechanism 12 and impurity removal mechanism 13, a turning wheel 1 is arranged above the ship, and a cable 2 is wound on the turning wheel 1, and the turning wheel 1 is used to turn the cable The line 2 is reeled, and a support 3 is fixedly installed on the ship. A motor 4 for driving is fixedly installed on the support 3. The output shaft of the motor 4 is fixedly connected with the rotating wheel 1. Two fixed blocks 5 are fixedly installed below the ship. A rotating bar 6 is connected in a rotating manner, a...

Embodiment 2

[0049] On the basis of Example 1, such as Figure 9 , Figure 10 , Figure 11 , Figure 14 and Figure 15 As shown, a cleaning mechanism 14 is also included. The cleaning mechanism 14 is used to clean up the algae in the fixed frame 121. The floating collection frame 10 is rotatably connected with a cleaning mechanism 14. The cleaning mechanism 14 includes a first rotating claw 141, a second Two rotating claws 142, rack 143, outer filter screen 144, gear 145, fixed plate 146, block 147 and second back-moving spring 148, the first rotating claw 141 that is connected with the rotating type on the floating collecting frame 10, the second rotating claw 142 is also rotatably connected to the floating collection frame 10. The first rotating claw 141 and the second rotating claw 142 are in contact with each other. The first rotating claw 141 and the second rotating claw 142 are used to pick up the seaweed and put it back into the ocean. The left side of 121 is fixedly connected w...

Embodiment 3

[0052] On the basis of Example 1, such as Figure 10 and Figure 11 As shown, a sloping plate 15 is also included, and the sloping plate 15 is fixedly installed on the floating collection frame 10, and the sloping plate 15 is used to separate the larger suspended particles of the micro-surface water from the ocean water body.

[0053] Larger suspended particles in the micro-surface water will enter the bottom frame 125 through the bottom of the sloping plate 15, and marine water and microplastic particles will enter the fixed frame 121 from above the sloping plate 15, thereby achieving a larger suspension of the micro-surface water The purpose of separating particulate matter and microplastic particles.

Abstract

The invention relates to the field of ecological environment detection, in particular to an ocean micro-surface water micro-plastic collecting device which comprises a rotating wheel, a cable, a support, a motor, a fixing block and the like. A rotating wheel is arranged above the ship, a cable is wound on the rotating wheel, a support is fixedly installed on the ship, a motor is fixedly installed on the support, an output shaft of the motor is fixedly connected with the rotating wheel, and two fixing blocks are fixedly installed below the ship. The marine water body is filtered through the first-stage filter screen and the second-stage filter screen, so that micro plastic particles in the marine water body are collected between the first-stage filter screen and the second-stage filter screen, and the purpose of screening the micro plastic particles with the same particle size is achieved.

Description

technical field [0001] The invention relates to the field of ecological environment detection, in particular to a device for collecting microplastics in marine microsurface water. Background technique [0002] The millimeter-thick "skin" of the ocean surface is called the ocean microsurface, which is the interface of the ocean's "water-air" exchange. Its surface tension and viscous secretions from microorganisms make it easy for tiny particles to gather in this layer. When studying the form and concentration of microplastics in microsurface water, it is necessary to collect samples of microplastic particles enriched in microsurface water according to requirements, and to detect the content of microplastics in water according to the amount of microplastic particles. Provide detection data for ecological environment protection and microplastic pollution control. [0003] At present, microplastic sample collection devices in marine water bodies are mostly aimed at water bodies...
