[0033] The working process of the present invention is as follows: Put the obtained biological resources into the cleaning chamber 22, and add water into the cleaning chamber 22, causing the lifting lead screw 25 to rotate, thereby driving the lifting threaded cylinder 15 to move downward, driving the fixed ring 3 to move downward, driving the cover plate 4 to move downward to cover the filter cleaning cylinder 2. Start the cleaning motor 5, which drives the cleaning rotating shaft 23 to rotate, driving the cleaning rod 24 to rotate, thereby realizing the cleaning of biological resources. The cleaning electric push rod 27 moves, driving the cleaning brush 28 to move downward close to the partition plate 6. The cleaning rod 24 rotates, driving the cleaning brush 28 to rotate to clean the biological resources near the partition plate 6, preventing sedimentation and incomplete cleaning. After passing through the filter plate 31, it enters the separation chamber 89. The filter plate 31 filters large-volume biological resources. After the cleaning is completed, start the partition motor, driving the partition gear shaft 34 to rotate, driving the partition gear 30 to rotate. The partition gear 30 meshes with the partition plate 6, causing the lower part of the cleaning chamber 22 to open, and the cleaned biological resources pass through the filter plate 31 and enter the separation chamber 89. After the cleaning and filtering are completed, pull the handle 20 to extract the baffle 19 from the extraction slot 18, and clean the biological resources filtered on the filter plate 31 through the extraction slot 18. The planktonic animals and plants and liquid after cleaning and filtering enter the separation chamber 89. Turn on the light source 55 to emit light. The light passes through the transparent partition 56 into the separation chamber 89 above the transparent partition 56. The planktonic animals are attracted by the light source and move closer to the transparent partition 56. Near the transparent partition 56, the planktonic plants are above the planktonic plant filter net 35, and the planktonic plants cannot pass through the planktonic plant filter net 35. When all the planktonic animals above the planktonic plant filter net 35 are below the planktonic plant filter net 35, start the driving motor 69, driving the driving shaft 70 to rotate, driving the driving main bevel gear 68 to rotate. The driving main bevel gear 68 meshes with the driving sub-bevel gear 67, driving the bevel gear shaft 75 to rotate, driving the driving bevel gear 74 to rotate. The driving bevel gear 74 meshes with the driven bevel gear 72, driving the closing gear shaft 45 to rotate, driving the closing gear 44 to rotate. The closing gear 44 meshes with the closing plate 65, driving the closing plate 65 to move, causing the two closing plates 65 to move together and merge, thereby realizing the separation of the upper and lower sides of the planktonic plant filter net 35, making the planktonic plants located above the planktonic plant filter net 35 and the planktonic animals located below the planktonic plant filter net 35, thus realizing the separation between planktonic animals and plants. Start the first extraction pump 13,Thus, phytoplankton and the aqueous solution enter the first extraction rack 80 through the first extraction tray 81, causing the first extraction closing lead screw 77 to rotate, thereby driving the first extraction closing plate 78 to move upward, thus opening the first extraction chamber 41, causing the first extraction lead screw 37 to rotate, thereby driving the first extraction nut block 40 to move, thus driving the first extraction chamber 41 to move, thereby driving the first extraction electric push rod 79 to move, thus driving the first extraction rack 80 to move, thereby driving the first extraction tray 81 to move into the separation chamber 89. The distance between the first extraction tray 81 and the phytoplankton filter screen 35 is adjusted through the separation chamber 89 to facilitate the extraction of the phytoplankton adsorbed on the phytoplankton filter screen 35. The phytoplankton and the aqueous solution enter the first extraction rack 80 through the first extraction tray 81, then enter the first extraction pipe 42, pass through the first extraction pipe 42 and enter the first extraction pump 13, and are discharged through the first discharge pipe 14 and enter the first collection bottle 8 for collection. The second extraction closing lead screw 83 is rotated, thereby driving the second extraction closing plate 84 to move upward, thus opening the second extraction chamber 85, causing the second extraction lead screw 47 to rotate, thereby driving the second extraction nut block 46 to move, thus driving the second moving plate 49 to move, thereby driving the second extraction electric push rod 53 to move, thus driving the second extraction rack 52 to move, thereby driving the second extraction tray 51 to move. The distance between the second extraction tray 51 and the transparent partition 56 is adjusted through the second extraction electric push rod 53 to facilitate the better extraction of zooplankton. The second extraction pump 16 is started, so that the zooplankton enters the second extraction rack 52 through the second extraction tray 51, passes through the second extraction pipe 50 and enters the second extraction pump 16, and is discharged through the second discharge pipe 17 and enters the second collection bottle 10 for collection. The cleaning closing lead screw 87 is rotated, thereby driving the cleaning closing plate 57 to move upward, thus opening the cleaning chamber 86, causing the cleaning lead screw 63 to rotate, thereby driving the cleaning nut block 64 to move, thus driving the cleaning moving plate 61 to move, thereby driving the cleaning scraper 58 to move. When the cleaning scraper 58 moves to the side close to the second extraction chamber 85, the cleaning electric push rod 60 is driven to move, thereby driving the cleaning scraper 58 to move downward and contact the surface of the transparent partition 56. The cleaning closing lead screw 87 rotates in the reverse direction, thereby driving the cleaning nut block 64 to move, thus driving the cleaning moving plate 61 to move, thereby driving the cleaning electric push rod 60 to move, thus driving the cleaning scraper 58 to move to scrape the garbage adhered to the surface of the transparent partition 56, and the garbage is discharged through the discharge channel 21, thus realizing the cleaning.
