[0002] Surface phytoplankton is widely distributed in the ocean. In particular, due to global warming and industrialization and agricultural activities in coastal areas, a large amount of nutrients flow into the ocean, causing surface phytoplankton to grow rapidly in the nearshore ocean and accumulate in large quantities on the ocean surface, squeezing the living space of other marine organisms and affecting the stability of the marine ecosystem. The large accumulation of surface phytoplankton on the nearshore surface will affect the beauty of the beach, reduce the attractiveness of coastal tourism, and cause economic losses to the tourism industry in coastal cities. When surface phytoplankton gathers in large quantities on the nearshore surface, it may entangle speedboat propellers, affecting navigation safety and increasing maintenance costs. However, surface phytoplankton can also be used as a plant in food, feed, medicine and other fields. Therefore, based on the current status of offshore surface phytoplankton cleaning, there is an urgent need for a cleaning equipment that can not only clean surface phytoplankton, but also efficiently compress and dehydrate it for subsequent use.

The rollers are composed of three fan assemblies uniformly distributed along the circumference of the main shaft 5. The main shaft 5 and each fan assembly are matched through two hollow shafts 6. The hollow shaft 6 is matched with the fan assembly, and the fan assembly can move to a certain extent along the hollow shaft 6 (the fan assembly can shrink and extend axially along the direction of the hollow shaft 6 on the main shaft 5).

The housing I33 is mounted on the hull 46. A boss 34 is provided on one side of the housing I33, and a climbing conveyor belt is fixedly connected to the boss 34. A downwardly inclined discharge port is provided on the other side of the housing I33, and a feed inlet is provided above the housing I33. The motor support plate 27 is mounted on the housing I33, and the motor 28 is mounted on the motor support plate 27. Multiple gears 29 are meshed and connected in sequence and are all located outside the housing I33. The central axes of the multiple drive shafts 30 are parallel, and each gear 29 is connected to a drive shaft 30, which is inserted and connected to the interior of the housing I33. The output end of the motor 28 is connected to a gear 29. A plurality of circular gaskets 32 and a plurality of circular blades 31 are installed in the middle of the transmission shaft 30. The plurality of circular blades 31 and the plurality of circular gaskets 32 are alternately distributed on the transmission shaft 30. The circular blades 31 and the circular gaskets 32 cooperate to crush the phytoplankton on the sea surface entering the feed port when the transmission shaft 30 rotates.

[0047] like Figure 10As shown, the compression dehydration mechanism has a housing II 36 with a drainage channel 38 and a feed hopper 35, a water filter 37, a spiral shaft 40, and a spiral blade 41. The water filter 37, the spiral shaft 40, and the spiral blade 41 are all arranged inside the housing II 36. The feed hopper 35 is arranged on the side of the housing II (36) close to the crushing mechanism, and the feed hopper 35 is connected to the discharge port of the crushing mechanism; the spiral shaft 40 is provided with a spiral blade 41, the water filter 37 is arranged outside the spiral shaft 40, and the water filter 37 is provided with a plurality of water filter holes 39. The housing II A drainage channel 38 is provided inside 36, and the drainage channel 38 is located below the water filter net 37 and the spiral shaft 40. The water filter net 37 can filter the crushed sea surface phytoplankton and drain the water through the drainage channel 38; the shaft diameter of the spiral shaft 40 gradually increases in the direction away from the feed hopper 35, and the pitch of the spiral blade 41 gradually decreases, and the space for transporting sea surface phytoplankton continues to shrink, so that the seawater is squeezed out, and the spiral blade 41 can clean the sea surface phytoplankton on the water filter net 37, so that the mechanism can operate continuously and not be blocked.

[0048] like Figure 11 As shown, the collection mechanism includes a drainage trough 44, a sea surface phytoplankton collection box 43, and a seawater collection box 45; the sea surface phytoplankton collection box 43 and the seawater collection box 45 are both installed on the hull 46, and a discharge channel 42 is provided above the sea surface phytoplankton collection box 43. The sea surface phytoplankton collection box 43 is connected to the compression and dehydration mechanism through the discharge channel 42 to collect the sea surface phytoplankton that has been crushed, compressed, and dehydrated; one side of the drainage trough 44 is connected to the drainage channel 38 of the compression and dehydration mechanism, and the other side is connected to the seawater collection box 45, and surrounds the outer periphery of the sea surface phytoplankton collection box 43 and is located below the discharge channel 42. The drainage trough 44 has a certain inclination angle leading to the seawater collection box 45, which can ensure that seawater can flow smoothly into the seawater collection box 45.

[0049] The working principle of the present invention is: The main shaft 5 of the cleaning mechanism rotates to drive the drum to rotate, and the phytoplankton on the sea surface is wrapped around the retractable fan 1 provided with thorns 3; as the drum rotates, the comb teeth 10 on the combing shaft 9 with a fixed angle comb the phytoplankton on the drum.

[0050] The combed phytoplankton on the sea surface will fall onto the anti-slip corrugated conveyor belt Ⅰ15 of the straight conveyor belt. As the conveyor belt runs, the phytoplankton on the sea surface will be transported to the climbing conveyor belt Ⅱ22 and then fall into the crushing mechanism.

[0051] After the collected phytoplankton on the sea surface enters the crushing mechanism, the motor 28 drives the transmission shaft 30 to rotate. The circular blade 31 on the transmission shaft 30 and the circular gasket 32 ​​cooperate closely to crush the phytoplankton on the sea surface, and enter the compression and dehydration mechanism through the inclined discharge port.

[0052] The phytoplankton on the sea surface enters the compression and dehydration mechanism from the feed hopper 35. As the screw shaft 40 rotates, the phytoplankton on the sea surface is pushed forward by the spiral blades 41 fixed on the screw shaft 40. As the forward distance becomes farther and farther, the diameter of the screw shaft 40 continues to increase and the pitch of the spiral blades 41 continues to decrease, and the space left for the phytoplankton on the sea surface gradually becomes smaller. The seawater is squeezed into the drainage channel 38 through the water filter hole 39, and flows into the seawater collection box 45 through the drainage trough 44 with an inclined angle, while the phytoplankton on the sea surface enters the phytoplankton collection box 43 through the discharge channel 42.
