The operation method of this embodiment includes the following steps.
When collecting microplastics in seawater by the microplastic gradient collecting device of the present invention, the specific operation process is as follows.
First, the vertical connection rod 20 is placed in the mounting chamber 10 and moved down with each filtration collection disk 21 so that the water bottle 110 sequentially passes through the corresponding sliding vertical groove 210 on the side wall of each filtration collection disk 21. When the bottommost filtration collection disk 21 is placed in the engaging round groove 120,

Is fixed to the upper end of the mounting chamber 10.
Next, the collection box 1 is connected to the closing cover 100 by an external lifting device and placed in the sea area where collection is required, the underwater moving body 4 is activated by the controller 50, and the collecting box 1 is different using the underwater moving body 4. Move to deep waters and collect microplastics.
After that, when the collection box 1 is moved to the seabed at a fixed depth, the microplastics in the seawater are collected, and when the collection is performed, the seawater is filtered by the sieving filter screen 1100 to remove solid impurities in the seawater before entering. The water cylinder 110 enters the mounting chamber 10 and drops into the uppermost filtration collection disk 21, and the microplastics in the seawater are filtered by the plurality of overlapping filtration sheets 22 in the filtration collection disk 21, and the filtered seawater is collected. After passing through the second filtration collection disk 21, the microplastics in seawater are filtered twice by the 15 overlapping filtration sheets 22 in the second filtration collection disk 21 to separate the microplastics of the corresponding particle size. Then, the filtered seawater sequentially passes through each filtration collection disk 21 at the lower end to separate the 40, 60, and 80 mesh microplastics, and when the filtration of the seawater is completed, it may flow out from the bottom end of the mounting chamber 10.
Finally, the underwater moving body 4 moves the collection box 1 to the initial position, the external lifting device lifts the collection box 1, then the closing cover 100 is removed, and the handle 200.
The vertical connection rod 20 is lifted from the mounting chamber 10 using , Microplastics of different particle sizes are quickly collected in the corresponding primary storage box 3 via the addition port 211.

Example 2
This embodiment is substantially the same as that of Example 1 except for the following.
As shown in FIGS. 7 and 8, a receiving groove 221 is provided on each filtration sheet 22, and a filtration hole 220 is uniformly provided on the side wall of the receiving groove 221 on one side of the filtration sheet 22 close to the vertical connection rod 20. An arc-shaped seal ring 23 is provided, and a lifting ring 22 is provided on the filtration sheet 22.
2 is provided, and the seawater that has fallen on the upper side of the filtration sheet 22 is collected and filtered by the installation of the receiving groove 221. By installing an arc-shaped seal ring 23, each filtration sheet 2
The space between 2 and the vertical connection rod 20 is sealed to prevent unfiltered seawater from flowing to the bottom filtration collection disk 21 through the gap between the filtration sheet 22 and the vertical connection rod 20, and microplastics with different particle sizes. By installing the lifting ring 222, it is possible to separate the filtration sheets 22 that are in contact with each other when collecting the microplastic after being filtered, and the microplastic is added to the addition port 211. Quickly falls into the primary storage box 3 via.

Example 3
This embodiment is substantially the same as that of Example 2 except for the following.
As shown in FIG. 2, the side wall located on the outer side of the collection box 1 of the water bottle 110 has a mesh structure, and the rotary cylinder 112 is connected to the front side of the water bottle 110 via a rotation shaft.
Fifteen crushing blades 1120 are provided along the circumferential direction on the side wall, an annular holder 1121 is provided outside the rotary cylinder 112, and four serrated strips 1122 are provided along the circumferential direction on the annular holder 1121 for collection. When the box 1 moves into the seawater by the drive of the underwater moving body 4, the rotary cylinder 112 rotates due to the impact force of the seawater, and at the same time, the crushing blade 11 on the rotary cylinder 112 rotates.
Since 20 also rotates, when the plants in the water area are cut by the rotation of the crushing blade 1120, the aquatic plants are entangled or adhered on the crushing blade 1120. The rubbing of the aquatic plants on the shaped strip 1122 and the crushing blade 1120 causes the entangled aquatic plants to fall from the crushing blade 1120, ensuring normal operation of the gradient collector and causing the action of the aquatic plants to drop or damage related members. It can be avoided.

Example 4
This embodiment is substantially the same as that of Example 3 except for the following.
As shown in FIG. 1, the liquid leveling plate 213, which is the uppermost filtration collection disk 21 and is provided on the lower side of the water inlet 11, has a radius gradually increasing from the inside to the outside on the bottom surface thereof as shown in FIG. Four annular drainage ditches 2130 are uniformly provided, and a plurality of dispersion holes 2131 are uniformly provided on each annular drainage groove 2130, and as shown in FIG. 4, on the annular drainage ditches 2130 distributed from the inside to the outside. The number of dispersion holes 2131 is 21, 12, 8 and 4, respectively, and the water flow of the water inlet 11 first flows into the outermost annular drainage ditch 2130, and the outermost annular drainage ditch 2130.
If it falls from each of the corresponding dispersion holes 2131 above and the water flow is relatively large, the outer annular drainage ditch 2
Since the number of dispersion holes 2131 provided on the 130 is relatively small, it cannot be drained immediately. At this time, the water flow gradually covers the entire liquid leveling plate 213 from the outside to the inside, and the inner annular drainage groove 2130 is on the outside. Because it is larger than the number of dispersion holes 2131 provided on the annular drainage groove 2130, it can be drained quickly, and therefore, in order to balance the liquid level of the liquid leveling plate 213, a water flow flows into the inner annular drainage groove 2130. In this way, the water flow uniformly flows through the dispersion holes 2131 in the filtration collection disk 21, and the water flow falling speed in the inner annular drainage groove 2130 is high, but the filtration sheets 22 are concentrated on each other and the center is convex. Since it has an arcuate structure, when a water flow falls on each filtration sheet 22, it flows to the edge of the filtration sheet 22 along the arcuate structure, and microplastics in seawater are filtered through each filtration sheet 22 during the flow process. , It is possible to avoid a decrease in filtration collection efficiency due to water flow accumulation on the filtration collection disk 21.
