However, in actual use, water on the deck may carry impurities or debris with it. These impurities and debris can affect the operation of the discharge structure, as well as the check valves and one-way valves used for backflow prevention, leading to backflow failure. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] Please see Figures 1-2 This utility model discloses a flow-guiding and backflow-preventing ship drainage structure, including a deck 1, a baffle plate 10 installed on one side of the deck 1, a connecting pipe 11 provided at the lower part of the baffle plate 10, a connecting pipe 13 connected at the lower part of the connecting pipe 11, a collection pipe 14 connected at one end of the connecting pipe 13, and an anti-backflow component 2 provided at the lower part of the collection pipe 14, wherein:

[0023] The anti-backflow assembly 2 includes a cleaning chamber 200 and a turbine fan 201. The cleaning chamber 200 is installed at the bottom of the collection pipe 14. A filter plate 207 is slidably connected to the inner wall of the cleaning chamber 200. The turbine fan 201 is located on the inner wall of the collection pipe 14. A transmission rod 204 is connected to the inner wall of the turbine fan 201. An installation plate 205 is installed on the bottom surface of the transmission rod 204. A brush 206 is provided on the bottom surface of the installation plate 205.

[0024] A coarse screen 12 is installed on the inner wall of the connecting pipe 11. A bearing 203 is provided on the outer surface of the transmission rod 204. A support plate 202 is installed on the outer surface of the bearing 203. A door 208 is installed on one side of the cleaning chamber 200. A pump 209 is connected to the lower part of the cleaning chamber 200. A one-way valve 210 is provided at the lower part of the pump 209.

[0025] There are eight baffles 10, with four baffles 10 forming a group. Two groups of baffles 10 are equidistantly arranged on both sides of the deck 1. Each baffle 10 has a connecting pipe 11 at its lower part, which is connected to the top surface of the deck 1. The baffles 10 are used to intercept large impurities. Each connecting pipe 11 has a coarse screen 12 on its inner wall. The coarse screen 12 is detachable. There are two connecting pipes 13, which are equidistantly arranged on both sides of the lower part of the deck 1.

[0026] As water flows through the main pipe 14, the turbine fan 201 rotates due to the impact of the water flow, driving the transmission rod 204 to rotate. The transmission rod 204 is fixed by the bearing 203 and the support plate 202 to reduce friction. The mounting plate 205 rotates with the transmission rod 204, driving the brush 206 to clean the surface of the filter plate 207 and prevent debris accumulation. The water flow further filters fine particles through the filter plate 207, ensuring the cleanliness of the discharged water. The one-way valve 210 allows water to flow out in only one direction to prevent seawater backflow. Example 2

[0027] Based on the above embodiment 1, please refer to Figures 3-5 Each connecting pipe 13 is fixedly connected to its corresponding upper connecting pipe 11. The inner wall of the connecting pipe 13 is in communication with the inner wall of the connecting pipe 11. The top ends of two connecting pipes 13 and a summing pipe 14 are fixedly connected to each other. The inner wall of the summing pipe 14 is in communication with the inner wall of the connecting pipe 13.

[0028] A one-way valve 210 is located in the middle of the inner wall of the collection pipe 14. The bottom inner wall of the one-way valve 210 is fixedly connected to the upper outer surface of the transmission rod 204. The lower inner wall of the collection pipe 14 is fixedly connected to the outer surface of the support plate 202. The inner wall of the support plate 202 is fixedly connected to the outer surface of the bearing 203. The inner wall of the bearing 203 is fixedly connected to the outer surface of the transmission rod 204.

[0029] The bottom surface of the collection pipe 14 is fixedly connected to the top surface of the cleaning chamber 200, the inner wall of the collection pipe 14 is connected to the inner wall of the cleaning chamber 200, the bottom surface of the transmission rod 204 is fixedly connected to the top surface of the mounting plate 205, and several brushes 206 are equidistantly installed on the bottom surface of the mounting plate 205.

[0030] The inner wall of the cleaning chamber 200 has two filter plates 207 that are slidably connected. The filter plates 207 are located below the brush 206. A chamber door 208 for sealing is rotatably connected to one side of the cleaning chamber 200. A pump 209 is connected to the lower part of the cleaning chamber 200 through a pipe. A one-way valve 210 is connected to the lower part of the pump 209 through a pipe.

[0031] When natural drainage is insufficient, such as during heavy rain or when excessive water accumulates on the deck, pump 209 is activated. Pump 209 draws water from the cleaning chamber 200 through pipes, accelerating the drainage process. The one-way valve 210 downstream of pump 209 remains closed to prevent seawater backflow.

[0032] The working principle and usage process of this utility model are as follows: Water accumulated on deck 1 is guided to the inlet of connecting pipe 11 through baffle plate 10. Baffle plate 10 intercepts large impurities (such as floating objects, leaves, etc.). When the water enters connecting pipe 11, coarse screen 12 further filters large particles to prevent blockage of subsequent pipes. The filtered water flows into connecting pipe 13 through connecting pipe 11, and the two connecting pipes 13 converge the water flow into the main pipe 14.

[0033] Backflow prevention and self-cleaning stage: When water flows through the main pipe 14, the turbine fan 201 rotates due to the impact of the water flow, driving the transmission rod 204 to rotate. The transmission rod 204 is fixed by the bearing 203 and the support plate 202 to reduce friction. The mounting plate 205 rotates with the transmission rod 204, driving the brush 206 to clean the surface of the filter plate 207 and prevent debris accumulation. The water flow further filters fine particles through the filter plate 207 to ensure the cleanliness of the discharged water. The one-way valve 210 allows water to flow out in only one direction to prevent seawater backflow.

[0034] Pump-assisted drainage stage: When natural drainage cannot meet the demand, such as during heavy rain or when there is excessive water accumulation on the deck, pump 209 is activated. Pump 209 draws water from the cleaning chamber 200 through the pipeline, accelerating the drainage speed. The one-way valve 210 downstream of pump 209 remains closed to prevent seawater backflow.

[0035] Maintenance and Cleaning: Open the chamber door 208, remove the filter plate 207 and clean away any debris. Disassemble the removable coarse screen 12, and clean or replace it. Ensure that the one-way valve 210 is free from jamming and has a good seal.
