When the displacement frame 29 moves reciprocally, the linkage push rod 34 will also move synchronously, and when the linkage push rod 34 moves reciprocally, it will drive the pressurizing disc 32 to move reciprocally in the pressurizing cylinder 28, and when the pressurizing disc 32 moves reversely, it will suck the sewage in the sewer pipe 8 into the pressurizing cylinder 28, and when the pressurizing disc 32 moves forward, it will quickly press the sewage in the pressurizing cylinder 28 out, so that the sewage can be quickly pressurized and pushed, thereby exerting a pushing force on the sewage from right to left (as shown in the drawings), so that the sewage is more easily pushed into the drainage pipe 4, thereby effectively accelerating the drainage efficiency of the sewage in the drainage pipe 4.

[0051] The greater the water volume of the sewage, the faster the driving roller 11 rotates, and the reciprocating speed of the pressurizing disc 32 also increases synchronously, and the speed of the pressure exerted on the sewage also increases synchronously, thereby providing a more rapid pushing force on the sewage, that is, the greater the water volume of the sewage, the faster the pushing efficiency, and the faster the drainage efficiency, so that the drainage efficiency of the sewage can be adaptively adjusted according to the water volume of the sewage. ​

[0052] The specific working principle of the present drainage device is as follows: the sewage on the deck of the ship falls into the water collecting frame 1, the large impurities in the water collecting frame 1 are filtered and removed through the impurity removing grid plate 3, the sewage continues to fall after being filtered through the impurity removing grid plate 3 and then contacts the filtering blocking rod 7, at this time, the small impurities in the sewage are blocked by the filtering blocking rod 7, thereby realizing secondary filtration of the impurities in the sewage.

[0053] The sewage continues to fall after passing through the filtering blocking rod 7 and then falls into the water collecting box 10 and then falls into the sewer pipe 8 through the water collecting box 10, the sewage in the sewer pipe 8 is then discharged through the drain pipe 4, thereby completing automatic discharge of the sewage on the deck of the ship, the sewage flows downward after entering the sewer pipe 8, the sewage contacts the runner blade 12 in the sewer pipe 8 when falling, at this time, the runner blade 12 rotates under the action of gravity and impact of the sewage, thereby driving the driving roller 11 to rotate synchronously.

[0054] The driving roller 11 drives the translation frame 18 to move reciprocally on the fixed frame 6 under the cooperation of the linkage assembly when rotating, the translation frame 18 drives the plurality of sleeved cleaning rings 26 and the plurality of middle cleaning rods 27 to move synchronously when moving, the plurality of sleeved cleaning rings 26 clean and scrape off the impurities attached to the filtering blocking rod 7 when moving, the plurality of middle cleaning rods 27 scrape off the impurities blocked between two filtering blocking rods 7 when moving, so that the impurities cannot accumulate on the filtering blocking rod 7. The translation frame 18 drives the bearing box 23 below the translation frame 18 to move synchronously when moving, the bearing box 23 synchronously collects the impurities cleaned and scraped off by the sleeved cleaning rings 26 and the middle cleaning rods 27, so that the impurities cannot fall into the sewer pipe 8 when being cleaned, the impurities collected in the bearing box 23 fall into the impurity collecting box 13 under the cooperation of the impact of the sewage and gravity when the translation frame 18 moves to the leftmost side, thereby completing automatic cleaning and collection of the impurities, avoiding the impurities entering the sewage to cause blockage.

[0055] When the water volume is large, the driving roller 11 rotates at a higher speed, the driving roller 11 drives the locking disc 30 to rotate synchronously under the cooperation of the synchronous assembly, the locking disc 30 drives the displacement frame 29 to move horizontally reciprocally under the cooperation of the reciprocating assembly when rotating, the displacement frame 29 drives the linkage push rod 34 to move reciprocally synchronously when moving reciprocally, the linkage push rod 34 drives the pressurizing disc 32 to move reciprocally in the pressurizing cylinder 28 when moving reciprocally, the pressurizing disc 32 sucks the sewage in the sewer pipe 8 into the pressurizing cylinder 28 when moving reversely, and the pressurizing disc 32 rapidly discharges the sewage in the pressurizing cylinder 28 when moving forward, thereby realizing rapid pressurization and displacement of the sewage through reciprocation, thereby exerting a pushing force on the sewage from right to left, so that the sewage is more easily discharged into the drain pipe 4, thereby effectively accelerating the discharge efficiency of the sewage in the drain pipe 4.

[0056] The above merely provides the preferred embodiment of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art, according to the technical range disclosed by the present application and the inventive concept thereof, can make equivalent replacements or changes, and all of them should be covered in the protection scope of the present application.
