TECHNICAL FIELD

[0002] Microplastics have small particle sizes and are easily mixed with seawater, making it difficult to collect them efficiently through conventional salvage methods. Typically, a water pump is installed on a near-shore ship to suck seawater and microplastics through a suction pipe and a conical net, and then separate them in a collecting barrel to collect microplastics in the shallow ocean. However, there are still problems to be solved in traditional microplastic collecting ships.

[0018] As Figures 1 to 9As shown, the embodiment of the present application provides a water purifier based on a folding polypropylene carbon rod filter element, which comprises a hull 1 and a floating body 2 symmetrically fixed below the hull 1, a photovoltaic panel 3 is arranged on the hull 1, a through opening 4 is provided in the hull 1, a water pump 5 is connected to the inner side of the through opening 4 through a fixing component, a motor 6 is connected to the water pump 5, a flange pipe 7 is connected to the axial end of the water pump 5, a suction pipe 8 is connected to the lower end of the flange pipe 7, a conical net 9 is fixed to the lower end of the suction pipe 8, a discharge pipe 10 is connected to the radial end of the water pump 5, a supporting plate 12 is arranged on the hull 1, a collection barrel 13 is connected to the supporting plate 12, a drain pipe 14 is connected to the rear end of the collection barrel 13, a blocking net 15 is connected to the end of the drain pipe 14, a rudder 16 is symmetrically arranged through and below the rear end of the hull 1, a propeller 17 is connected to the rear end of the floating body 2, and the water purifier further comprises: A rotating protection part is arranged through the suction pipe 8 and located outside the conical net 9, which comprises a bearing 27 connected to the outer side of the upper end of the suction pipe 8, and the bearing 27 is fixed to the flange pipe 7 through a fixing component, a turbine 19 rotatably arranged at the center line of the suction pipe 8, and a supporting rod 24 symmetrically arranged outside the suction pipe 8, a rotating wheel 25 welded to the outer side of the supporting rod 24, and the rotating shaft of the turbine 19 is connected to the supporting rod 24 through a connecting component and sealingly penetrates the suction pipe 8, so as to rotate the conical net 9 and the rotating wheel 25 by using water flow, thereby preventing blockage; A collecting part is connected to the rear of the suction pipe 8 and has an input end located behind the conical net 9, which comprises a collecting piece fixed to the rear of the suction pipe 8 and located below the through opening 4, a collecting basket 32 placed in the collecting piece, and a winding piece rotatably arranged outside the flange pipe 7 and connected to the rotating protection part; A grinding protection part is translationally and symmetrically arranged at the bottom of the hull 1 and located below the rotating wheel 25, which comprises a supporting rotating piece translationally arranged at the bottom of the hull 1, the outer contour of the supporting rotating piece is the same as the outer contour of the floating body 2 close to the supporting rotating piece, and a grinding driving piece connected to the supporting rotating piece and located below the rotating wheel 25 and cooperable with the rotating wheel 25.

[0019] Specifically, the hull 1 provides support for the float 2, which is submerged in seawater under the weight of the hull 1 and all components mounted above it. This allows the float 2 to work with the seawater to provide buoyancy for the hull 1 to float on the sea surface. The hull 1 also provides stable support for the photovoltaic panel 3, which converts light energy into electrical energy to power the microplastic collection device. The opening 4 provides installation space for the water pump 5 and flange pipe 7, and also provides a through-channel for the suction pipe 8, allowing the suction pipe 8 to support the cone mesh 9 inserted into the seawater. A fixing plate 18 is welded to the outside of the water pump 5, and the fixing plate 18 is fixed to the hull 1 within the opening 4 by fixing components. The fixed connection allows the water pump 5 to support the motor 6 under the support of the fixed plate 18. The motor 6 can drive the water pump 5 to operate using the drive end, so that the water pump 5 can suck seawater and microplastics into the water pump 5 through the cone net 9, suction pipe 8 and flange pipe 7. The discharge pipe 10 can provide a channel for the seawater and microplastics in the water pump 5 to enter the discharge port 11. The discharge port 11 can provide a channel for the seawater and microplastics to enter the collection tank 13. The collection tank 13 can provide a collection space for microplastics. The net 15 can intercept microplastics and provide a channel for seawater to enter the drain pipe 14. The drain pipe 14 can provide a channel for seawater to be discharged into the ocean.

[0020] In practical application, the operator can float the hull 1 on the nearshore ocean using the float 2, and control the propeller 17 to rotate as needed. Simultaneously, the operator can adjust the angle of the rudder 16, allowing the hull 1 to move on the ocean under the propulsion of the propeller 17 and the steering adjustment of the rudder 16. Simultaneously, the hull 1 will move the collection bucket 13 via the support plate 12, and the motor 6 and discharge pipe 10 via the water pump 5, all moving together on the ocean. The operator needs to start the motor 6 to drive the water pump 5, causing the water pump 5 to operate through the flange pipe 7, suction pipe 8, and cone screen 9. Seawater and microplastics in the shallow ocean are drawn in, allowing them to pass through the cone mesh 9 into the suction pipe 8, then through the suction pipe 8 into the flange pipe 7, and finally through the flange pipe 7 into the water pump 5. From there, they are discharged through the water pump 5 into the discharge pipe 10, and through the ribs into the discharge outlet 11. Finally, the seawater and microplastics are discharged through the discharge outlet 11 into the collection tank 13. The seawater entering the collection tank 13 then passes through the barrier net 15 into the drain pipe 14, and is discharged from the stern of the hull 1 into the ocean. The microplastics are collected and stored in the collection tank 13.

[0021] In a preferred embodiment of the present invention, the rotating part includes a connecting rotating member and a rotating driving member. The connecting rotating member is connected to the flange 28, and the rotating driving member is disposed through the suction pipe 8. The connecting rotating member includes: A flange 28 is fixed to the outside of the bearing 27, and the flange 28 is fixedly connected to the flange pipe 7 through a fixing component; The upper end of the straw 8 is connected to the inner side of the bearing 27. The shift channel 20 is symmetrically located on the outside of the straw 8; Connecting rod 21 is symmetrically fixed to the outside of the turbine shaft of turbine 19; Support plate 22 is fixed to one end of connecting rod 21 and passes through sliding track 20; The support plate 22 is fixedly connected to the strut 24.

[0022] Specifically, flange 28 provides a through passage and support for bearing 27, bearing 27 provides rotational support for suction pipe 8, suction pipe 8 provides opening space for sliding channel 20, sliding channel 20 provides a through passage and lifting movement channel for support plate 22, turbine 19 provides support for connecting rod 21 so that connecting rod 21 supports support plate 22, and support plate 22 provides support for strut 24.

[0023] Rotary drive components include: The elastic membrane 23 is fixed to the outside of the support plate 22 and is fixedly connected to the inner wall of the sliding channel 20 to cooperate with the support plate 22 to seal the sliding channel 20; Multiple water holes 26 are evenly distributed throughout the interior of the rotating wheel 25; The end of the swivel 25 away from the straw 8 has an angle of inclination toward the axis.

[0024] Specifically, the straw 8 can support the elastic membrane 23 within the channel 20. The elastic membrane 23 is elastic and can deform under external force. When the external force disappears, it will rebound, allowing the support plate 22 to push and pull the elastic membrane 23 to deform under external force. The elastic membrane 23 can cooperate with the support plate 22 to close the channel 20. The support rod 24 can provide support for the rotating wheel 25 and drive the rotating wheel 25 to rotate together. The rotating wheel 25 can provide space for the water hole 26 to be opened. The water hole 26 can provide a passage for seawater and microplastics to pass through, allowing seawater and microplastics to enter the cone net 9. The rotating wheel 25 can also intercept marine debris or seaweed above it.

[0025] In practical application, when the water pump 5 draws in seawater, the seawater flowing through the conical mesh 9 into the suction pipe 8 and into the water pump 5 drives the turbine 19 to rotate within the suction pipe 8. Driven by the water flow, the turbine 19 propels the suction pipe 8 via the connecting rod 21 and the support plate 22. The suction pipe 8 rotates with the turbine 19, supported by the flange 28, around the bearing 27. Simultaneously, the support plate 22 drives the rotating wheel 25 to rotate via the support rod 24. Seawater and microplastics, under the action of the water pump 5, flow through the water hole 26, through the rotating wheel 25, and into the conical mesh 9, passing through the conical mesh 9 and entering the suction pipe 8. The suction pipe 8, during its rotation, drives the conical mesh 9 to rotate as well. The conical mesh 9 provides a channel for seawater and microplastics to enter the suction pipe 8, intercepts larger debris and seaweed in the ocean, and continuously flings away debris and seaweed using rotational power, preventing blockage of the water hole 26 and the conical mesh 9, thus providing protection for the conical mesh 9.

[0026] In a preferred embodiment of the present invention, the collecting component includes: Support tube 29 is fixed to the outer rear side of straw 8; The cone 30 is fixed to the inner wall of one end of the support cylinder 29 and is close to the suction tube 8 and the cone mesh 9; The through-net 31 is installed at the other end of the support tube 29; The collected parts are installed above the support cylinder 29 and connected to the support plate 12.

[0027] Specifically, the straw 8 provides support for the support tube 29, which in turn provides stable support for the cone 30. The cone 30 guides the garbage and seaweed, which pass through the cone 30 and enter the collection basket 32 ​​through the opening 34. The channel of the cone 30 gradually narrows from the outside to the inside, reducing the probability of the garbage and seaweed entering the collection basket 32 ​​being discharged back into the ocean. The net 31 provides a channel for seawater to exit the support tube 29, allowing seawater to flow through the cone 30, the support tube 29, and the net 31 when the hull 1 moves together with the support tube 29.

[0028] The collected parts include: A handle 33 is fixed above the collection basket 32 ​​and near the straw 8; The connecting strap 35 is fixed at one end to the upper end of the collection basket 32 ​​and located away from the handle 33, and the other end is fixedly connected to the tray 12. The opening 34 is opened through the side of the collection basket 32 ​​near the end of the cone 30, corresponding to the output end of the cone 30; A hanging ring 50 is welded onto the pipe 10.

[0029] Specifically, the collection basket 32 ​​provides a passage for seawater and microplastics, allowing the seawater and microplastics entering the collection basket 32 ​​to pass through the collection basket 32 ​​and be discharged into the support cylinder 29, and then through the net 31 to flow to the outside. The connecting strap 35 provides support and positioning for the collection basket 32 ​​under the support of the support plate 12, and the support cylinder 29 provides support for the collection basket 32 ​​so that the through hole 34 can be aligned with the cone cylinder 30. The drain pipe 10 provides support for the hanging ring 50, which provides a passage and support positioning for the rope. The collection basket 32 ​​can stably support the handle 33, and the handle 33 provides a knot connection position for one end of the rope.

[0030] The winding component includes: Push rod 36 is fixed to the upper end of support plate 22; Friction pad 37 is fixed to the upper end of push rod 36 and located outside flange 28; The wheel 38 is rotatably connected to the outside of the flange 28 and is located above the friction pad 37; The connecting ring 39 is fixed to the inside of the spool 38.

[0031] Specifically, the support plate 22 provides stable support for the push rod 36 and can drive the push rod 36 to rotate together. The push rod 36 can stably support the friction pad 37, which is made of rubber and is relatively rough, providing greater friction. The flange 28 provides rotational support for the winding wheel 38. The winding wheel 38 provides space for the rope to wind and coil, and can stably support the connecting ring 39. The connecting ring 39 provides a knotting connection position for the other end of the rope.

[0032] In practical application, when the ship 1 is sailing in the ocean, seawater will continuously pass through the cone 30 and the opening 34 into the collection basket 32. At the same time, the garbage and seaweed in the seawater will enter the collection basket 32 ​​along with the seawater. The seawater will pass through the collection basket 32 ​​and the net 31 and be discharged from the support cylinder 29, thereby achieving random collection of garbage and seaweed in the ocean.

[0033] In a preferred embodiment of the present invention, the support member includes: Electric rods 40 are symmetrically fixed to the bottom of hull 1; The support frame 41 is fixed below the telescopic end of the electric rod 40 by a connecting component; The rotating roller 42 is symmetrically arranged through the support frame 41 and is rotatably connected to the support frame 41; The inner support component is located inside the suction pipe 8 and the flange pipe 7, and is fixedly connected to the flange pipe 7.

[0034] Specifically, the electric rod 40 can provide stable support for the support frame 41 under the support of the hull 1, and the support frame 41 can provide rotational support for the rotating roller 42.

[0035] The internal support components include: The upper end of the fixed rod 47 is symmetrically fixed to the inner wall of the flange tube 7 by a fixing component, and extends to the inner side of the suction tube 8; The cone sleeve 48 is fixed to the lower end of the fixed rod 47 and is located above the turbine 19; The lifting rod 49 has a fixed end that is fixedly connected through the cone sleeve 48, and a telescopic end that is rotatably connected to the shaft of the turbine 19.

[0036] Specifically, the flange tube 7 can provide stable support for the fixed rod 47 through the fixing component, so that the fixed rod 47 can provide support for the tapered sleeve 48, the tapered sleeve 48 can provide support for the lifting rod 49, the lifting rod 49 can provide rotational support for the turbine 19 through the telescopic end, and can drive the turbine 19 to move up and down.

[0037] After the collection work is completed, the staff needs to keep the water pump 5 running, then take the rope, pass one end of the rope through the opening 4 and tie a knot on the outside of the handle 33, and then pass the other end of the rope through the outlet 11 and tie a knot between it and the hanging ring 50, connecting it to the outside of the connecting ring 39. Then, control the telescopic end of the lifting rod 49 to retract, so that the lifting rod 49 can drive the turbine 19 to move upward with the telescopic end under the support of the cone sleeve 48. The turbine 19 can drive the support plate 22 to move upward along the sliding track 20 through the connecting rod 21, and drive the push rod 36 and the support rod 24 to move upward together during the movement. At the same time, the support plate 22 will push and pull the elastic membrane 23 to deform or bend during the movement, so that the push rod 36 can drive the friction pad 37 to move upward together under the action of external force, so that the friction pad 37 rubs against the wheel 38, thereby allowing the turbine 19 to move upward. Driven by the water flow, the connecting rod 21 and the support plate 22 drive the suction pipe 8 and the push rod 36 to rotate together. The push rod 36 can drive the friction pad 37 to rotate together. The friction pad 37 can use the rotational power and friction to drive the wheel 38 to rotate together. The wheel 38 can be pulled by the connecting ring 39 to wind the rope inside the wheel 38. During the winding process, the rope can be pulled upward by the external force under the support and positioning of the hanging ring 50. The pull handle 33 pulls the collection basket 32 ​​and the garbage and water plants collected inside it upward under the action of external force. At the same time, the collection basket 32 ​​will drive the connecting belt 35 to move into the opening 4. As the rope is wound, the connecting belt 35 of the collection basket 32 ​​is straightened, and the collection basket 32 ​​can move into the opening 4, which makes it convenient for the staff to take out the garbage and water plants collected in the collection basket 32 ​​for cleaning.

[0038] The wear-driving components include: Rotary roller 43 is installed through the rotating support frame 41; Support roller 45 is fixed to the outside of the rotating wheel 25 and the rotating roller 42; An angled wheel 44 is fixed to the outside of the rotating roller 43 and located below the rotating wheel 25; Friction belt 46 is sleeved on the outside of support roller 45 and is in close contact with support roller 45; The outer contours of the friction band 46 and the support roller 45 can fit into the contour of the float 2.

[0039] Specifically, the support frame 41 provides rotational support for the rotating roller 43 and the rotating roller 42. The rotating roller 42 and the rotating roller 43 can stably support the support roller 45. The support roller 45 can use friction to drive the friction belt 46 to move, and the support roller 45 can provide positioning and rotational support for the friction belt 46. The rotating roller 43 can provide support for the angled wheel 44. The rotating wheel 25 can use its tilt angle to fit with the angled wheel 44, and can use rotational power to drive the angled wheel 44 to rotate, so that the angled wheel 44 can drive the rotating roller 43 to rotate together, and then the rotating roller 43 can drive the support roller 45, and cooperate with the support roller 45 to drive the friction belt 46 to rotate.

[0040] In practical application, the operator can first control the electric boom 40 to retract as needed, so that the electric boom 40, supported by the hull 1, uses its telescopic end to move the support frame 41 towards the float 2. The support frame 41, through the rotating roller 43, rotating roller 42, and support roller 45, can move the friction belt 46 and the angled wheel 44 together, allowing the friction belt 46 to fit against the outer contour of the float 2 located below the hull 1. Then, while keeping the motor 6 running, the operator can control the lifting boom 49 to extend as needed, so that the lifting boom 49, supported by the cone sleeve 48, pushes the turbine 19 downwards. The turbine 19, through the connecting rod 21 and support plate 22, drives the support rod 24 and the rotating wheel 25 downwards, allowing the rotating wheel 25 to move downwards until it fits against the angled wheel 44. This allows the rotating wheel 25 to drive the angled wheel 44 to rotate using rotational power and friction. The angled wheel 44, in turn, drives the rotating roller 43 and the support roller 45 on the outside of the rotating roller 43 to rotate together under the support of the support frame 41. The support roller 45 on the outside of the rotating roller 43 can then drive the friction belt 46 to rotate in the direction of rotation using friction. At the same time, the friction belt 46, under the action of external force, uses the friction with the support roller 45 on the outside of the rotating roller 42 to drive the rotating roller 42 to rotate under the support of the support frame 41. This allows the friction belt 46 to rotate and use the rotational motion and its own friction to remove the barnacles attached to the float 2 located below the hull 1, making the barnacle cleaning work convenient and avoiding the problem of the side of the float 2 located below the hull 1 being inconvenient to clean.

[0041] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
