Description

Technical Field

[0001] The utility model mainly relates to the technical field of microplastic collection, and specifically relates to a marine microplastic collection device. Background Art

[0002] Microplastics refer to plastic particles with a diameter less than 5 millimeters and are a major carrier of pollution. In 2004, Thompson et al. from the University of Plymouth in the UK first proposed the concept of "microplastics" in a study on plastic debris in marine waters and sediments, defining it as plastic debris and particles with a diameter less than 5 millimeters. In fact, the particle size range of microplastics is from a few micrometers to a few millimeters, with various shapes and complex compositions. They are usually a mixture of plastic particles that are difficult to detect with the naked eye, so they are vividly called "PM2.5 in the ocean".

[0003] In order to reduce the harm of marine microplastics, many countries have started salvage and collection operations on microplastics in key areas because microplastics pose a serious threat to marine life. Many marine organisms ingest microplastics, which may lead to digestive tract blockage, limited nutrient intake, or even death. Microplastics may also adsorb toxic substances and have a profound impact on the entire marine ecosystem after entering the food chain. Moreover, microplastics are transmitted through the food chain and may ultimately enter the human diet system, posing a potential hazard to human health. Although the current research on the long-term effects of microplastics on humans is still ongoing, reducing their quantity can reduce the risk. Microplastics decompose extremely slowly and exist in the ocean for a long time, accumulating to form a greater environmental burden. By salvaging and cleaning microplastics, their long-term deposition in the ocean can be reduced, preventing more serious environmental pollution in the future.

[0004] The inventor found the following defects during the operation of specific embodiments:

[0005] During the process of salvaging and collecting microplastics, it was found that due to the different sizes of microplastics, if a net bag is used for salvage, if the mesh is too small, the water filtration will be very slow, resulting in low collection efficiency and the inability to classify and collect according to the size of microplastics. If the mesh is too large, microplastics with a smaller diameter cannot be salvaged.

[0006] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0031] Referring to the attached Figures 1-5 , a marine microplastic collection device includes a collection box 1. Water inlet holes 2 and water outlet holes are respectively opened on both sides of the collection box 1. A plurality of collection grooves 3 are opened at the top of the collection box 1. A partition plate 4 is arranged between the collection grooves 3. A plug-in groove 5 is opened in the middle of the partition plate 4. A filtering plug board 6 is slidably connected to the plug-in groove 5. A discharge port 7 is opened on the side of the collection groove 3. A closing door 8 is hinged at the top of the discharge port 7. This device can classify and collect microplastics of different sizes through the filtering plug board 6 with different sizes of filtering holes. It can not only collect microplastics of different sizes, but also prevent the low filtering efficiency caused by too small filter holes. When this device works, the marine garbage collection ship sails to the area where microplastics need to be collected, connects the water inlet hole 2 to the water pump for collecting marine microplastics. The water pump will send the seawater rich in microplastics into the collection box 1. The microplastics in the seawater will be filtered and collected layer by layer by the filtering plug board 6. After filtering and collecting for a period of time, the closing door 8 on the side can be opened to take out and collect the microplastics inside, and then the collection operation of microplastics can be completed.

[0032] The filter plug board 6 includes a support frame 61. A lifting handle 62 is connected to the top of the support frame 61. A first plugging chute 63 is formed on the side of the support frame 61. Second plugging chutes 64 are provided at both ends of the first plugging chute 63. The second plugging chutes 64 are matingly connected to support blocks 65. A filter net 66 is connected to the middle of the support blocks 65. The first plugging chute 63 is matingly connected to the filter net 66. After the filter plug board 6 works for a period of time, it needs to be replaced in time. When replacement is needed, the support frame 61 is lifted upward through the lifting handle 62, and then the support blocks 65 are taken out from the second plugging chutes 64 on the side, so that the entire filter net 66 can be taken out. Finally, a new filter net 66 is installed into the first plugging chute 63 through the support blocks 65. In order to filter and collect smaller microplastics, the filter net 66 can also be a filter membrane with a smaller pore size.

[0033] A cleaning mechanism 41 is connected to the water inlet side of the partition board 4. The cleaning mechanism 41 includes an L-shaped connecting block 42. A cleaning brush 43 is provided inside the L-shaped connecting block 42. The top two sides of the L-shaped connecting block 42 are detachably connected to the top of the collection box 1 through combining blocks 44. The cleaning brush 43 of this device is aligned with the direction of the filter net 66. When no collection operation is carried out, the filter plug board 6 can be reciprocated up and down, and then the substances attached to the filter net 66 can be initially scraped off by the cleaning brush 43, which can extend the service time of the filter net 66 and the filter plug board 6.

[0034] Sliding tracks 31 are symmetrically and spacedly formed at the top of the collection groove 3. The sliding tracks 31 are matingly connected to concave sliders 32. A discharge plate 33 is connected to the bottom of the concave sliders 32. The discharge plate 33 is slidably connected inside the collection groove 3. A rotating lead screw 34 is matingly connected to the middle of the concave sliders 32. A driving motor 35 is connected to the end of the rotating lead screw 34. The discharge plate 33 is normally located on the side away from the discharge port 7. When the closing door 8 is opened, it is necessary to discharge the microplastics collected in the collection groove 3 at intervals. At this time, the driving motor 35 rotates, and then the discharge plate 33 is moved towards the discharge port 7 through the rotating lead screw 34, facilitating the removal of the internal microplastics.

[0035] There are four collection grooves 3. The pore size of the filter net 66 gradually decreases from the water inlet hole 2 towards the water outlet hole. In this embodiment, there are four collection grooves 3. It should be noted that the actual number of collection grooves 3 can be determined according to the size and total amount of marine microplastics. The pore size of the filter net 66 can be selected and adjusted according to the situation of marine microplastics. The collection grooves 3 first filter and collect large microplastics, and then filter and collect small microplastics.

[0036] The above-described embodiments merely represent certain implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
