Description

Technical Field

[0001] The present application relates to the technical field of ship drainage, and specifically to a ship drainage structure. Background Art

[0002] In addition to deck water, ships also need centralized drainage for domestic sewage and air conditioning condensate. With the increasing number of water-using appliances in ship cabins, drainage needs are also increasing. With increasingly stringent regulations, this type of wastewater cannot be discharged directly into the sea or river.

[0003] Therefore, ships are usually equipped with special water tanks for collecting domestic sewage, and before discharge, chemical substances are generally used to decompose organic matter before being discharged into the sea, or filtering devices are used to remove solid particles before being discharged into the sea.

[0004] However, when using a filter device to filter solid particles, since some particles are sticky, such as grease, colloid, etc., they easily adhere to the surface of the filter device to form a layer of sticky substance, blocking the flow of liquid, resulting in poor filtration effect, thereby affecting drainage efficiency. Therefore, it is necessary to provide a ship drainage structure to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the Invention

[0012] A scraping mechanism is provided above the filter screen, the scraping mechanism comprising a fixed pipe connected to the drain pipe, a piston slidably connected to the interior of the fixed pipe, a scraper fixedly mounted on the lower end of the piston, and an end surface of the scraper affixed to the surface of the filter screen;

[0013] A driving mechanism is provided on both sides of the upper end of the piston, and is used for driving the piston to move up and down in the fixed tube.

[0014] Furthermore, the driving mechanism has a base fixedly mounted on the outside of the fixed pipe, the base is located at the upper end of the drain pipe, a rack ring is fixedly mounted on the upper end of the base, a fixed frame is fixedly mounted on one side of the rack ring, the upper end of the fixed frame is rotatably connected to a rotating shaft, and the rotating shaft is located at the center of the rack ring.

[0015] Furthermore, a drive motor is fixedly mounted on the outer side of the fixed frame, the output shaft of the drive motor is fixed on the rotating shaft, the inner side of the rack ring is meshed with a gear, a connecting rod is rotatably connected to the center of the gear, and the other end of the connecting rod is fixedly mounted on the rotating shaft.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0032] like Figure 1As shown, the present application provides a ship drainage structure, including a water tank 1, a support bracket 11 is fixedly installed at the lower end of the water tank 1, and a plurality of connecting pipes 12 are connected to the upper end of the water tank 1. The connecting pipes 12 are used to connect to the sewage pipes in the ship's cabin room;

[0033] In addition, a drain pipe 13 is connected to one side of the bottom end of the water tank 1. The drain pipe 13 is used to discharge all the waste water and particulate matter in the water tank 1. It should be noted that the drain pipe 13 will only be opened for discharge when the ship arrives at the port or sewage treatment plant.

[0034] At the same time, the other side of the water tank 1 is connected to a drain pipe 14. The height of the drain pipe 14 is higher than that of the sewage pipe 13. Therefore, the sewage entering the water tank 1 will first be precipitated and separated. When there is a lot of sewage, the drain pipe 14 will be opened for drainage. At this time, most of the fixed particulate matter will settle at the bottom of the water tank 1 to prevent the fixed particulate matter from completely blocking the drain pipe 14.

[0035] like Figure 2-Figure 3 As shown, a filter 15 is fixedly installed inside the drain pipe 14, and the filter 15 blocks fixed particles from entering the water tank 1. In order to prevent sticky particles such as grease and colloid from adhering to the surface of the filter 15, a scraping mechanism 2 is provided above the filter 15, and the scraping mechanism 2 is used to scrape the surface of the filter 15;

[0036] The scraping mechanism 2 includes a fixed pipe 21 connected to the top of the drain pipe 14 through a pipe. A piston 22 is slidably connected to the interior of the fixed pipe 21, and a scraper 23 is fixedly mounted on the lower end of the piston 22. The end surface of the scraper 23 is attached to the surface of the filter 15. At the same time, a driving mechanism 3 is provided on both sides of the upper end of the piston 22. The driving mechanism 3 is used to drive the piston 22 to move up and down in the fixed pipe 21, thereby driving the scraper 23 to move up and down on the surface of the filter 15.

[0037] The driving mechanism 3 has a base 31 fixedly mounted on the outside of the fixed pipe 21. The base 31 is located at the upper end of the drain pipe 14. A rack ring 32 is fixedly mounted on the upper end of the base 31. At the same time, a fixing frame 34 is fixedly mounted on one side of the rack ring 32. The upper end of the fixing frame 34 is rotatably connected to a rotating shaft 35. The rotating shaft 35 is located at the center of the rack ring 32. A driving motor 37 is also fixedly mounted on the outer side of the fixing frame 34. The output shaft of the driving motor 37 is fixed to the rotating shaft 35. Therefore, when the driving motor 37 is started, the rotating shaft 35 can be driven to rotate.

[0038] At the same time, the inner side of the rack ring 32 is meshed with a gear 33, and the center of the gear 33 is rotatably connected to a connecting rod 36, and the other end of the connecting rod 36 is fixedly mounted on the rotating shaft 35. Therefore, when the rotating shaft 35 rotates, it drives the gear 33 to perform a circular motion inside the rack ring 32;

[0039] In addition, the other side of the gear 33 is rotatably connected to a driving rod 38, and the other end of the driving rod 38 is hinged to the upper end of the piston 22. Therefore, starting the drive motor 37 can cause the rotating shaft 35 to drive the gear 33 to perform a circular motion, and the driving rod 38 moves at the same time. During this process, the driving rod 38 will push the piston 22 to slide up and down in the fixed tube 21, and drive the scraper 23 to scrape the surface of the filter screen 15, thereby preventing sticky particles such as grease and colloid from adhering to the surface of the filter screen 15 and preventing the filter screen 15 from being blocked.

[0040] like Figure 4 As shown, the connecting pipe 12 has a vertical pipe 121 connected to the water tank 1, and one side of the vertical pipe 121 is connected to a horizontal pipe 122. At the same time, a floating rod 124 is slidably connected to the upper end surface of the vertical pipe 121, and a floating plate 123 is fixedly installed at the lower end of the floating rod 124. When sewage enters the horizontal pipe 122, the floating plate 123 moves upward due to the buoyancy, thereby opening the vertical pipe 121, allowing the sewage to enter the water tank 1 through the vertical pipe 121;

[0041] In the present application, the floating plate 123 is initially located at the connection between the horizontal pipe 122 and the vertical pipe 121 and closes the vertical pipe 121, thereby blocking the vertical pipe 121 when there is no sewage flowing, preventing the odor in the water tank 1 from floating upward.

[0042] In summary, when it is necessary to discharge the sewage in the water tank 1, the drain pipe 14 is opened and the drive motor 37 is started at the same time, so that the sewage in the water tank 1 is discharged outward through the drain pipe 14, and the filter 15 will filter the fixed particles floating in the sewage;

[0043] At the same time, the driving motor 37 drives the gear 33 to perform circular motion, and moves the piston 22 up and down, driving the scraper 23 to move up and down on the filter screen 15, thereby scraping off the fixed particles on the filter screen 15 to prevent them from adhering to the surface of the filter screen 15 and blocking the flow of liquid, thereby ensuring the filtering effect and improving the drainage efficiency.

[0044] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
