[0030] Wherein, the bottom of the bottom filter plate 16 is provided with a connecting seat 17, the inside of the connecting seat 17 is provided with a funnel-shaped inclined surface, the bottom of the connecting seat 17 is provided with a first drainage opening 18, through the setting of the funnel-shaped inclined surface, the water flow is more concentrated and discharged, and the discharge speed is accelerated.

[0031] Wherein, the bottom side of the connecting rod 9 is provided with multiple cutting blades 10, through the cooperation of multiple cutting blades 10, the weeds and debris at the second drainage opening 19 of the water bottom can be broken, preventing the second drainage opening 19 from being blocked by the debris, so that the water in the drainage groove 2 is hindered when being discharged, affecting the drainage efficiency.

[0032] Wherein, the bottom of the drainage groove 2 is provided with a second drainage opening 19, and the second drainage opening 19 is correspondingly provided with the first drainage opening 18.

[0033] The working principle of the embodiment is as follows: when water accumulates in the cabin of the ship, the water flows into the water inlet of the drainage groove 2. At this time, the drainage filter plate 3 can preliminarily intercept large sundries in the water flow to prevent large sundries from entering the inside of the drainage system. The water flow that passes through the drainage filter plate 3 continues to flow downward and sequentially passes through a plurality of filter plates 16 that are arranged equidistantly from top to bottom. The filter plates 16 filter sundries in the water flow, and small sundries are blocked on the filter plates 16. The filtered water flow passes through the first drainage opening 18 at the connecting seat 17 and is finally discharged out of the ship body 1 through the second drainage opening 19. Since the connecting seat 17 is internally provided with a funnel-shaped inclined surface, the water flow is more concentrated and the discharge speed is accelerated due to the guidance of the inclined surface, so as to ensure the drainage efficiency. During the drainage process, the plurality of cutting blades 10 installed at the bottom of the connecting rod 9 continuously rotate. The connecting rod 9 is driven to rotate by the motor 8, so as to drive the cutting blades 10 to rotate and cut and break sundries such as grass and debris that may exist at the second drainage opening 19, so as to avoid that the sundries block the second drainage opening 19 and ensure the smoothness of the drainage. In order to prevent the filter plates 16 from being blocked due to the accumulation of small sand or other sundries after long-term use, when backwashing is needed, the control valve 12 installed at the water inlet of the conveying pipe 13 is opened. The water flow enters the conveying pipe 13 from the control valve 12, and then enters the connecting pipe 14 in communication with the conveying pipe 13 through the conveying pipe 13. The plurality of nozzles 15 on both sides of the connecting pipe 14 spray the water flow out to backwash the surfaces of the filter plates 16. The impact force of the water flow can wash away the sundries attached to the filter plates 16. The sundries washed away are finally discharged from the second drainage opening 19 with the water flow. The whole backwashing process does not need manual cleaning of workers, saves manpower, ensures long-term effective use of the drainage system, and improves the safety of the ship.
