[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the cleaning component is driven by the driving component to move back and forth in the fresh water tank, and the microorganisms in the fresh water are captured in the first plate-shaped filter membrane and the second plate-shaped filter membrane. The first plate-shaped filter membrane swings back and forth on the horizontal plane, while the second plate-shaped filter membrane moves up and down on the vertical plane. The microorganisms in the fresh water are filtered by staggered movement. The staggered movement route can avoid the filtering effect from being affected by the water flow direction, and play a role in improving the filtering effect. Filtering out the microorganisms can avoid the contamination of the fresh water tank by microorganisms, and solve the problem of rapid reproduction of bacteria, fungi, algae and other organisms in the tank. During the movement of the second plate-shaped filter membrane, the extension plate can move along The steering plate moves in the direction of the connecting frame to ensure that the docking rod can adapt to the rectangular connecting frame. Under the push of the docking rod, the second plate-shaped filter membrane will move in the vertical plane. During the up and down movement of the second plate-shaped filter membrane, the limit plates located at both ends of the second plate-shaped filter membrane can ensure that the second plate-shaped filter membrane is always in a horizontal state, ensuring that the second plate-shaped filter membrane will not rotate under the resistance of water. During the process when the second plate-shaped filter membrane does not move up and down, the limit plates are separated from the connecting frame, so that the second plate-shaped filter membrane can rotate with the docking rod as the center, but the rotation range is still limited by the limit plates. The active state can help the second plate-shaped filter membrane expand the filtration range at the highest and lowest points.

[0020] 2. In the present invention, a trapezoidal slide groove is provided inside the steering plate, and the trapezoidal slide groove is mainly used to limit the extension plate, and determine the moving route of the extension plate while preventing the extension plate from detaching from the steering plate. Since the positioning rod and the driven gear at the top of the connecting frame are connected to the inside of the fan-shaped plate, and the steering plate is fixedly installed at the end of the gear shaft, and the gear shaft is meshed with the bevel gear, during the movement of the first plate-shaped filter plate, it will swing under the action of water resistance, so that the driven gear moves in the arc-shaped strip hole. With the use of the convex toothed belt, the driven gear can drive the bevel gear through the transmission rod, so as to achieve the purpose of driving the steering plate to rotate, and provide a power source for the up and down movement of the second plate-shaped filter membrane.

[0021] 3. In the present invention, the disc is driven by a reduction motor. During the rotation of the disc, the connecting rod in the protrusion drives the double-headed rotating rod, and the double-headed rotating rod drives the bending rod to rotate back and forth with the positioning hole as the center, so as to achieve the purpose of driving the fan-shaped plate to rotate back and forth. The rotation of the fan-shaped plate can ensure that the driven gear will move in the arc-shaped strip hole, and when the driven gear moves to the end of the arc-shaped strip hole, the rotation of the fan-shaped plate will directly drive the entire first plate-shaped filter membrane to move, so that the first plate-shaped filter plate will move in the arc direction, which can not only stir the fresh water to move irregularly and improve the filtering effect of the first plate-shaped filter plate itself, but also form an angle difference with the second plate-shaped filter membrane to improve the filtering effect of the second plate-shaped filter membrane.

Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown: a fresh water tank anti-pollution device for a deck transport ship, comprising a carrying frame 1, a movable rod 2 is slidably connected to the upper surface of the carrying frame 1, a driving component 4 is fixedly installed on the top of the movable rod 2, a cleaning component 5 is rotatably connected to the output end of the driving component 4, and a reduction motor 9 is fixedly connected to the input end of the driving component 4;

[0034] The cleaning assembly 5 includes a first plate-shaped filter membrane 51 and a second plate-shaped filter membrane 53. A connection frame 52 is fixedly connected to one side of the first plate-shaped filter membrane 51. Limiting plates 55 are fixedly installed at both ends of the second plate-shaped filter membrane 53. The limiting plates 55 are located at the edge of the connection frame 52. A docking rod 513 is slidably connected inside the second plate-shaped filter membrane 53. One end of the docking rod 513 is slidably connected to the inside of the connection frame 52. A receiving groove 54 is provided at the intersection of the connection frame 52 and the docking rod 513.

[0035] A reinforcement rod 57 is fixedly installed on the inner wall of the connecting frame 52, a support seat 517 is fixedly installed on the upper surface of the reinforcement rod 57, a gear shaft 518 is rotatably installed inside the support seat 517, one end of the gear shaft 518 is fixedly connected to a steering plate 510, an extension plate 58 is slidably connected inside the steering plate 510, and one end of the extension plate 58 is rotatably connected to the docking rod 513.

[0036] In this embodiment, the entire device mainly filters out microorganisms in fresh water by the fan-shaped back and forth movement of the first plate-shaped filter membrane 51 and the up and down movement of the second plate-shaped filter membrane 53. When in use, the entire device is fixedly installed on the top of the fresh water tank through the carrying frame 1. The length of the carrying frame 1 is smaller than the length of the fresh water tank. During the travel of the ship, under the action of inertia, the movable rod 2 can extend the direction of the carrying frame 1. During the movement, the reduction motor 9 drives the driving component 4, and the cleaning component 5 cleans the microorganisms in the fresh water. The reduction motor 9 is connected in parallel to the circuit in the ship.

[0037] The first plate-shaped filter membrane 51 is connected to the fan-shaped plate 46 in the driving assembly 4. When the driving assembly 4 directly drives the first plate-shaped filter membrane 51, the first plate-shaped filter membrane 51 will laterally filter out microorganisms in the fresh water. In the process of the first plate-shaped filter membrane 51 moving, the gear shaft 518 will be driven to rotate. When the gear shaft 518 rotates, it will drive the steering plate 510. Since the second plate-shaped filter membrane 53 is connected to the extension plate 58 in the steering plate 510 through the docking rod 513;

[0038] by Figure 2 For example, during the rotation of the steering plate 510, the extension plate 58 will push the docking rod 513 to move in the connection frame 52. The connection frame 52 is provided with a receiving groove 54 to receive the docking rod 513. When the docking rod 513 moves along the bottom horizontal side of the connection frame 52, the second plate-shaped filter membrane 53 itself can rotate with the docking rod 513 as the center of the circle. The limit plate 55 will determine the rotation range of the second plate-shaped filter membrane 53. Under the action of water resistance, the second plate-shaped filter membrane 53 swings back and forth within a certain range, thereby completing the filtration of microorganisms in fresh water.

[0039] When the docking rod 513 moves from the horizontal side at the bottom of the connecting frame 52 to the vertical side on the left, the limit plates 55 at both ends of the second plate-shaped filter membrane 53 will be placed on the connecting frame 52 to ensure that the second plate-shaped filter membrane 53 will not rotate. In the subsequent movement of the docking rod 513 along the vertical side of the connecting frame 52, the second plate-shaped filter membrane 53 will be directly driven to move upward until the docking rod 513 moves to the horizontal side at the top of the connecting frame 52 and contacts the transmission rod 515.

[0040] During the process of the disk 41 rotating from 90 to 270 degrees, the fan-shaped plate 46 will be driven to rotate in the opposite direction. At this time, the first plate-shaped filter membrane 51 will also reverse, and the gear shaft 518 will drive the steering plate 510 to rotate in the opposite direction, so that the docking rod 513 first drives the second plate-shaped filter membrane 53 to move downward, and then the docking rod 513 returns to the bottom horizontal edge and then moves to the right vertical edge. At this time, the docking rod 513 will drive the second plate-shaped filter membrane 53 upward, so that the second plate-shaped filter membrane 53 swings for a period of time, moves upward for a period of time, and moves downward for a period of time. The reverse rotation of the steering plate 510 also has the same effect.

[0041] The first plate-shaped filter membrane 51 and the connecting frame 52 are reinforced with structural strength by a reinforcement rod 57 , and a support seat 517 is provided on the upper surface of the reinforcement rod 57 to determine the position of the gear shaft 518 , thereby determining the rotation center of the steering plate 510 .

[0042] Embodiment 2: According to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, a trapezoidal slide groove 511 is provided inside the steering plate 510, and the extension plate 58 is slidably connected inside the trapezoidal slide groove 511. A limit block 512 is fixedly installed at one end of the steering plate 510, and a rectangular hole 59 is provided inside the extension plate 58. The limit block 512 is located inside the limit block 512. The steering plate 510 and the extension plate 58 are both located between the first plate-shaped filter membrane 51 and the second plate-shaped filter membrane 53. A driven gear 514 is rotatably installed on the top of the connecting frame 52, and a transmission rod 515 is fixedly connected to the bottom of the driven gear 514. The other end of the transmission rod 515 is fixedly installed with a bevel gear 5 16. The bevel gear 516 is meshedly connected with the gear of the gear shaft 518. A positioning rod 56 is fixedly installed on the top of the connecting frame 52. One end of the positioning rod 56 is rotatably connected to the inside of the fan plate 46. The driven gear 514 is movably connected to the inside of the fan plate 46. An arc-shaped strip hole 48 is opened at the intersection of the fan plate 46 and the driven gear 514. A convex tooth belt 49 is fixedly installed on the inner wall of the arc-shaped strip hole 48. The convex tooth belt 49 is meshedly connected with the driven gear 514. The positioning rod 56 is located at the corner of the connecting frame 52, and the driven gear 514 is located on the center line of the connecting frame 52.

[0043] In this embodiment, the driven gear 514 and the positioning rod 56 at the top of the connecting frame 52 are connected to the inside of the sector plate 46, wherein the position of the positioning rod 56 is fixed to determine the rotation center of the connecting frame 52. Figure 4For example, when the sector plate 46 starts to rotate five degrees clockwise, the first plate-shaped filter membrane 51 will not rotate, but the driven gear 514 will move in the arc-shaped strip hole 48. Under the interaction between the driven gear 514 and the convex toothed belt 49, the driven gear 514 will rotate, and the bevel gear 516 at the end of the transmission rod 515 drives the gear shaft 518, providing a power source for the movement of the second plate-shaped filter membrane 53.

[0044] When the driven gear 514 moves to the end of the arc-shaped strip hole 48, the fan-shaped plate 46 will continue to rotate. In this process, the fan-shaped plate 46 will directly drive the first plate-shaped filter membrane 51 to move in an arc-shaped route to filter the microorganisms in the fresh water horizontally.

[0045] A trapezoidal slide groove 511 is provided inside the steering plate 510 to accommodate the extension plate 58. A rectangular hole 59 is provided inside the extension plate 58 to be connected to a limit block 512 in the trapezoidal slide groove 511. The limit block 512 is used to prevent the extension plate 58 from being completely separated from the steering plate 510. The trapezoidal slide groove 511 can prevent the extension plate 58 from detaching from the steering plate 510 while determining the moving route of the extension plate 58.

[0046] Embodiment 3: According to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the driving assembly 4 includes a disc 41 and a double-headed rotating rod 44, the center of the disc 41 is fixedly connected to the output end of the reduction motor 9, a protrusion 42 is fixedly installed at the edge of the disc 41, a connecting rod 43 is fixedly installed inside the protrusion 42, one end of the connecting rod 43 is rotatably connected to one end of the double-headed rotating rod 44, one end of the double-headed rotating rod 44 is rotatably connected to a bending rod 45, one end of the bending rod 45 is fixedly connected to a fan-shaped plate 46, a positioning hole 47 is provided at the bending portion of the bending rod 45, the bending rod 45 is rotatably installed at the bottom of the movable rod 2 through the provided positioning hole 47, vertical rods 7 are fixedly installed at both ends of the movable rod 2, the bottom of the vertical rod 7 is slidably connected to the inside of the carrying frame 1, a guide slot 6 is provided at the junction of the carrying frame 1 and the vertical rod 7, one end of the carrying frame 1 is fixedly connected to a support plate 8, a partition plate 3 is fixedly installed on the upper surface of the movable rod 2, the reduction motor 9 is fixedly installed on the upper surface of the partition plate 3, and the disc 41 is located on the lower surface of the partition plate 3.

[0047] In this embodiment, the disc 41 in the driving assembly 4 is connected to the reduction motor 9 on the partition plate 3. When the reduction motor 9 drives the disc 41, the connecting rod 43 in the protrusion 42 at the edge of the disc 41 drives the double-headed rotating rod 44, which is mainly connected to the connecting rod 43 and the bending rod 45. Figure 4For example, when the disc 41 rotates 90 degrees clockwise, the double-headed rotating rod 44 will push the bending rod 45 to rotate clockwise with the positioning hole 47 as the center. When the disc 41 rotates between 90 degrees and 270 degrees, the double-headed rotating rod 44 will pull the bending rod 45 to rotate counterclockwise with the positioning hole 47 as the center. When the disc 41 rotates between 270 degrees and 360 degrees, the double-headed rotating rod 44 will push the bending rod 45 to rotate clockwise with the positioning hole 47 as the center. When the disc 41 continues to rotate, the bending rod 45 will swing back and forth with the positioning hole 47 as the center and drive the fan-shaped plate 46.

[0048] The movable rod 2 is connected to the guide groove 6 of the carrying frame 1 through the vertical rod 7. During the ship's travel, under the influence of inertia and the inclination of the hull, the movable rod 2 can move along the direction of the carrying frame 1, thereby changing the positions of the first plate-shaped filter membrane 51 and the second plate-shaped filter membrane 53 in the fresh water tank. The support plate 8 can ensure the structural stability of the carrying frame 1 without affecting the normal movement of the movable rod 2.

[0049] The use method and working principle of the device: the whole device is fixedly installed on the roof of the fresh water tank through the carrying frame 1, and the support plate 8 can ensure the structural stability of the carrying frame 1. During the ship's travel, under the influence of inertia and the tilt of the hull, the movable rod 2 can move along the direction of the carrying frame 1, thereby changing the position of the first plate-shaped filter membrane 51 and the second plate-shaped filter membrane 53 in the fresh water tank. In this process, the reduction motor 9 continuously drives the disc 41;

[0050] The connecting rod 43 at the edge of the disk 41 drives the double-headed rotating rod 44 to Figure 4 For example, when the disc 41 rotates ninety degrees clockwise, the double-headed rotating rod 44 will push the bending rod 45 to rotate clockwise with the positioning hole 47 as the center, and when the sector plate 46 starts to rotate five degrees clockwise, the first plate-shaped filter membrane 51 will not rotate, but the driven gear 514 will move to one end of the arc-shaped strip hole 48. Under the action of the convex toothed belt 49, the driven gear 514 will drive the gear shaft 518 through the bevel gear 516 at the end of the transmission rod 515, and the gear shaft 518 will then drive the docking rod 513 to move along the route of the connecting frame 52 through the extension plate 58 in the steering plate 510, so that the second plate-shaped filter membrane 53 moves upward;

[0051] When the disc 41 rotates between 90 and 270 degrees, the sector plate 46 rotates counterclockwise, causing the driven gear 514 to move from one end of the arc-shaped strip hole 48 to the other end. During this process, the second plate-shaped filter membrane 53 moves downward first, and then moves upward after maintaining a horizontal state for a period of time. After the driven gear 514 moves to the end of the arc-shaped strip hole 48, the sector plate 46 drives the first plate-shaped filter membrane 51, causing the first plate-shaped filter membrane 51 to move in an arc-shaped route to filter the microorganisms in the fresh water horizontally.

[0052] When the disc 41 rotates between 270 and 360 degrees, the double-headed rotating rod 44 will push the bending rod 45 to rotate clockwise around the positioning hole 47. The above steps can be repeated to clean the microorganisms in the fresh water tank.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
