Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, and specifically relates to a protective cover for the suction pipe of the anti-rollover compartment of a roll-on / roll-off ship. Background Technology

[0002] Based on the design and structure of the anti-roll tank injection pipe on the PCTC roll-on / roll-off ship, a protective cover needs to be added to the injection port. Seawater is injected into the anti-roll tank via ballast pumps, or the water in the anti-roll tank is discharged via ballast pumps, necessitating the addition of a protective cover at the anti-roll tank suction port. Conventionally, after the pipeline enters the tank, a U-shaped design is used, with a suction port added to the end of the pipeline, and a circular anti-impact plate added to the structural surface. The disadvantage is that impurities can easily enter the pipeline, causing blockages and equipment damage. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a protective cover for the suction pipe of the anti-roll tank on a roll-on / roll-off ship. The installation process is simple and also facilitates crew members entering the anti-roll tank to inspect its interior.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A protective cover for the suction pipe of a roll-on / roll-off (Ro-Ro) ship's anti-roll tank is provided. The end of the suction pipe is bent vertically upward and fixedly connected to the bottom surface of the anti-roll tank. The protective cover is located inside the anti-roll tank and fixedly connected to the bottom surface of the anti-roll tank. The end port of the suction pipe is located inside the protective cover. The protective cover includes a square bracket. Filter plates are provided on the top surface and all four sides of the square bracket. At least one side of the filter plate is rotatably connected to the square bracket. At the same time, a detachable connection node is provided between the filter plate and the square bracket on one side of the rotatable connection point.

[0005] Furthermore, the upper part of one of the filter plates is rotatably connected to the square bracket via multiple hinges.

[0006] Furthermore, the square bracket is formed by multiple fixed square steel bars, including a top square frame and legs vertically positioned below the four corners of the top square frame.

[0007] Furthermore, at least one set of ear plates is provided mirror-symmetrically on the legs on both sides of the filter plate, which is rotatably connected to the square bracket. The central axis of the ear plate hole is perpendicular to the filter plate. Nuts are fixed on the ear plates, and the filter plate is detachably connected to the ear plates by bolts.

[0008] Furthermore, the ear plate is disposed on the opposite sides of the two legs, and the ear plate is located inside the filter plate.

[0009] Furthermore, the filter plate is a steel plate with uniformly distributed filter holes, and the steel plate is embedded between the top square frame and two adjacent legs.

[0010] This utility model of a protective cover for the suction pipe of the anti-heeling compartment on roll-on / roll-off (Ro-Ro) ships is increasingly being used in practice. The solution is simple to construct and convenient to maintain. From the perspective of later ship operation and maintenance, it will make it easier for crew members to carry out inspections and repairs, saving time and costs and improving efficiency.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1-3 As shown, a protective cover for the suction pipe of the anti-roll tank of a roll-on / roll-off ship is provided. The end of the suction pipe 7 is bent vertically upward and fixedly connected to the bottom surface of the anti-roll tank. The protective cover is located inside the anti-roll tank and fixedly connected to the bottom surface of the anti-roll tank. The end port of the suction pipe 7 is located inside the protective cover. The protective cover includes a square bracket 1. Filter plates 2 are provided on the top surface and all four sides of the square bracket 1. At least one side of the filter plate 2 is rotatably connected to the square bracket 1. At the same time, a detachable connection node is provided between the filter plate 2 and the square bracket 1 on one side of the rotatable connection point.

[0017] Specifically, in this embodiment, one of the four side filter plates 2 is rotatably connected to the square bracket 1 via multiple hinges 3.

[0018] The square bracket 1 is formed by multiple fixed square steel bars 11, including a top square frame and legs that are vertically arranged below the four corners of the top square frame.

[0019] Furthermore, at least one set of ear plates 4 are mirror-symmetrically arranged on the legs on both sides of the filter plate 2, which is rotatably connected to the square bracket 1. The central axis of the ear plate hole of the ear plate 4 is perpendicular to the filter plate 2. Nuts 5 are fixed on the ear plate 4. The filter plate 2 is detachably connected to the ear plate 4 by bolts 6.

[0020] To facilitate installation and ensure a clean appearance of the protective cover, the ear plate 4 is located on the opposite sides of the two legs, and the ear plate 4 is located inside the filter plate 2; the filter plate 2 is a steel plate with evenly distributed filter holes, and the steel plate is embedded between the top square frame and the two adjacent legs.
