[0002] In recent years, environmental pollution and ecological and human health risks caused by microplastics have attracted great attention at home and abroad, becoming a new type of global environmental pollutant. Microplastics refer to plastic particles with a particle size of less than 5 mm. Microplastics have the characteristics of small particle size, large quantity, continuous enrichment in the water environment, and can serve as a carrier for the transfer of various pollutants. They can also enter the human body through food, drinking water and other channels, threatening human health.

[0003] The devices and methods for collecting microplastics in water bodies have not yet been standardized and normalized. Microplastic samples in water bodies are generally collected using trawls or buckets. In the existing technology, they are generally collected manually on the shore by pulling the trawls with ropes, which is time-consuming and labor-intensive, and is greatly affected by the environment on both sides of the river, making it inconvenient to collect. In addition, the trawls are inconvenient to assemble and disassemble, affecting the use effect. Utility Model Content

[0024] Example:

[0025] Reference Figure 1-Figure 5A microplastic collection device for urban rivers includes a collecting tube 1 and a trawl 2. A plurality of grooves 101 are provided on the outer wall of the collecting tube 1. The grooves 101 are provided with two to six groups. Here, we prefer two groups. One end of the trawl 2 is fixed in the groove 101 through an elastic band 5, that is, the mouth of the trawl 2 is sleeved on the outer wall of the collecting tube 1, and then the elastic band 5 is sleeved in the groove 101 to fix the trawl 2 on the collecting tube 1. The assembly and disassembly is convenient and the fixing effect is reliable. Here, a clamp can also be used. The clamp can be sleeved in the groove 101 to fix the trawl 2 on the collecting tube 1. In addition, multiple groups of support rings 3 are fixedly arranged in the trawl net 2, and the support rings 3 are arranged in two to six groups. Here, we prefer four groups, and the four groups of support rings 3 are equidistantly distributed along the axial direction of the trawl net 2, and the diameters of the four groups of support rings 3 are successively reduced along the feeding direction of the trawl net 2. When in use, by fixing the support rings 3 in the trawl net 2, the trawl net 2 can be supported to a certain extent, assisting its unfolding, reducing adhesion, and improving the use effect; hulls 103 are fixedly arranged on both sides of the collecting barrel 1, propellers are arranged in the tails of the two groups of hulls 103, and motors for driving the two groups of propellers to rotate respectively are fixedly arranged in the two groups of hulls 103, and solar panels are fixedly arranged on the two groups of hulls 103, which can provide emergency power supply for the motor and improve its endurance. When in use, the collecting barrel 1 is moved in the river channel for collection by the hull 103. On the one hand, it can save time and effort, reduce manual labor intensity, and improve collection efficiency. On the other hand, it is less affected by the environment on both sides of the river channel, which can reduce collection dead angles and improve collection quality.

[0026] When in use, the collection tube 1 is moved in the river channel with the hull 103 for collection. On the one hand, it can save time and effort, reduce labor intensity, and improve collection efficiency. On the other hand, it is less affected by the environment on both sides of the river channel, which can reduce collection dead angles and improve collection quality. By opening a groove 101 on the outer wall of the collection tube 1 and using an elastic belt 5 to fix the trawl net 2 in the groove 101, the fixing effect is reliable, and it is easy to assemble and disassemble, thereby improving the use effect.

[0027] Reference Figure 4 A protrusion 102 is fixedly provided at the inner bottom of the groove 101. The protrusion 102 is evenly distributed along the circumference of the inner bottom of the groove 101, and the protrusion 102 has a hemispherical structure. When in use, by fixing the protrusion 102 at the inner bottom of the groove 101, the fixing effect of the trawl net 2 can be increased to prevent the trawl net 2 from slipping out of the groove 101 and affecting normal use.

[0028] Reference Figure 1 and Figure 3A mounting frame 4 is threadedly connected to the end of the collecting cylinder 1 away from the trawl net 2, and a filter screen 401 is fixedly arranged in the mounting frame 4. When in use, the mounting frame 4 is threadedly connected to the collecting cylinder 1, and the filter screen 401 is fixedly arranged on the mounting frame 4. On the one hand, it can reduce the entry of other larger garbage into the trawl net 2, such as branches, glass bottles, etc., thereby improving the collection effect of microplastics and preventing the trawl net 2 from being damaged. On the other hand, the mounting frame 4 is easy to assemble and disassemble, which is convenient for cleaning or replacing the filter screen 401, thereby improving the use effect.

[0029] Reference Figure 3 and Figure 5 , isolation pads 301 are fixedly arranged on the inner walls of the multiple groups of support rings 3, and multiple dividing lines are fixedly arranged on the isolation pads 301. The dividing lines can be one to eight. Here, we prefer three, and the angles between the three are equal. The multiple groups of dividing lines extend from the outer wall circumference of the two isolation pads 301 at the axis of the isolation pads 301, but do not extend to the outer wall circumference, and stop extending after a certain distance from the outer wall of the isolation pads 301; and the multiple groups of dividing lines are parallel to the radial lines, at this time, the isolation pads 301 are toward the trawl 2 The isolation pad 301 extends inside the trawl 2, and the material of the isolation pad 301 is rubber or silicone, preferably rubber. When in use, when the hull 103 carries the collecting tube 1 to collect microplastics in the river, when the water flows into the trawl 2, the isolation pad 301 can be unfolded along the dividing line and extended into the trawl 2, which makes it convenient for the microplastics to enter the trawl 2. However, when the collection is stopped, the isolation pad 301 is closed to prevent the microplastics collected in the trawl 2 from coming out of the trawl 2 and affecting the collection effect. The function of the isolation pad 301 is similar to a one-way valve.

[0030] Reference Figure 1-Figure 3 A discharge pipe 201 is fixedly provided at the other end of the trawl net 2, and a valve is fixedly provided on the discharge pipe 201. When in use, the microplastics collected in the trawl net 2 can be discharged by buckling the valve on the discharge pipe 201, which is convenient for subsequent use and improves the collection efficiency.
