Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and specifically relates to the arrangement structure of the suction pipe in the sewage well below the vehicle deck. Background Technology

[0002] With the continued boom in the Ro-Ro ship market in recent years, new technologies and innovations are emerging one after another, and shipowners' expectations and requirements for new ships are constantly increasing. Increasingly fierce competition and more stringent requirements are driving ship design to become more refined, with precise and standardized handling of the same details.

[0003] By tracking and comparing application examples of roll-on / roll-off deck sewage wells with different design routes on various types of ships, we found that flat-bottomed sewage wells are more efficient, easier to clean, and less prone to accumulating dirt and grime. The combination of a butterfly check valve and a suction filter offers superior suction performance compared to a plate check valve or a suction check valve combined with a suction filter. However, the arrangement of this butterfly check valve and suction filter combination on actual ships varies widely, with the overall problem being that the arrangement is not compact, occupies too much space, and fails to fully consider the structural integrity and the convenience of subsequent construction and maintenance. Therefore, new arrangement methods are needed to solve these problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a structural arrangement for the suction pipe in the sewage well below the vehicle deck, which is stable, efficient, and easy to install and maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An arrangement structure for a suction pipe in a sewage well below a vehicle deck includes a suction pipe and two seat plates. The suction pipe includes a straight pipe section and a curved pipe section. One end of the straight pipe section extends vertically through the side wall of the sewage well chamber into the sewage well and is connected to the curved pipe section through a check valve. The straight pipe section is fixedly connected to the side wall of the sewage well chamber at the point where it passes through the chamber. The two seat plates are spaced apart on both sides of the check valve. The seat plate closer to the straight pipe section is fixedly connected to the side wall of the sewage well chamber.

[0007] Furthermore, the check valve is a butterfly check valve, and the butterfly check valve is connected to the seat plate by bolts.

[0008] Furthermore, a sub-straight pipe section is provided between the seat plate near the bend section and the outlet end of the bend section, and one end of the sub-straight pipe section is fixedly connected to the seat plate.

[0009] Furthermore, the length of the sub-straight pipe section is not less than 80mm.

[0010] Furthermore, the distance between the top of the seat plate and the lower surface of the vehicle deck is not less than 50 mm.

[0011] Furthermore, an intake filter screen is provided on the outside of the inlet of the bend section. The intake filter screen is located at the bottom of the sewage well chamber. A reinforcing baffle is provided at the rib position and is installed in accordance with the hull profile. An arc-shaped through hole is provided on the reinforcing baffle. The two sides of the arc-shaped through hole extend to the bottom wall of the sewage well chamber through a smooth curve transition, and the lower ends of the two sides of the arc-shaped through hole are located on both sides of the intake filter screen.

[0012] Furthermore, the distance between the end of the reinforcing partition and the suction filter is not less than 50 mm.

[0013] The arrangement structure of the suction pipe in the sewage well under the vehicle deck of this utility model reduces space occupation by using a seat plate through the cabin instead of a sleeve through the cabin, uses a butterfly check valve instead of a plate check valve to reduce flow resistance and ensure stable check effect under extreme working conditions, and increases the flow area and improves suction efficiency by optimizing the bottom profile of the reinforcing baffle in the sewage well without reducing structural strength.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-2 As shown, an arrangement structure of a suction pipe in a sewage well below a vehicle deck includes a suction pipe 1 and two seat plates 2. The suction pipe 1 includes a straight pipe section 11 and a curved pipe section 12. One end of the straight pipe section 11 extends vertically through the side wall of the sewage well chamber into the sewage well and is connected to the curved pipe section 12 through a check valve. The straight pipe section 11 is fixedly connected to the side wall of the sewage well chamber at the point where it passes through the chamber. The two seat plates 2 are spaced apart on both sides of the check valve. The seat plate 2 closer to the straight pipe section 11 is fixedly connected to the side wall of the sewage well chamber.

[0019] Understandably, by using a seat plate 2 through the compartment instead of a sleeve through the compartment, the amount of welding work in the confined space on site was reduced.

[0020] Specifically, the check valve is a butterfly check valve 3, which is bolted to the seat plate 2. This configuration, using a butterfly check valve 3 instead of a plate check valve, reduces flow resistance and ensures stable check valve performance under extreme operating conditions.

[0021] To ensure stable flow through the disc of the butterfly check valve 3 and facilitate bolt removal, a sub-straight pipe section 4 is provided between the seat plate 2 near the bend section 12 and the outlet end of the bend section 12, and is coaxially arranged with the straight pipe section 11. One end of the sub-straight pipe section 4 is fixedly connected to the seat plate 2; the length of the sub-straight pipe section 4 is not less than 80mm.

[0022] Furthermore, to facilitate welding, the distance between the top of the seat plate 2 and the lower surface of the vehicle deck 5 is not less than 50mm.

[0023] Furthermore, an intake filter 6 is provided on the outside of the inlet of the bend section 12. The intake filter 6 is located at the bottom of the sewage well chamber. A reinforcing baffle 7 is provided at the rib position and is installed in conjunction with the hull profile. An arc-shaped through hole 71 is provided on the reinforcing baffle 7. The two sides of the arc-shaped through hole extend to the bottom wall of the sewage well chamber through a smooth curve transition, and the lower ends of the two sides of the arc-shaped through hole 71 are located on both sides of the intake filter 6.

[0024] This configuration optimizes the bottom profile of the reinforcing baffle 7 inside the sewage well, increasing the flow area and improving suction efficiency without reducing structural strength.

[0025] Furthermore, to ensure suction efficiency under extreme operating conditions, the distance between the end of the reinforcing baffle 7 and the suction filter 6 is not less than 50mm.

[0026] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
