Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a manhole cable pipe and a ship. Background Art

[0002] In the later stage of ship construction and commissioning, some equipment will be added according to the equipment interface or the needs of the shipowner, and it is inevitable to add cables at this time. However, in the later stage of ship construction, the cable holes have been completed and sealed and solidified, and the original cable holes cannot be used. At this time, the only way is to add cable penetrations by opening holes in the hull structure. Opening holes in the hull structure using fire operations will damage the original hull paint, increase polishing, secondary paint beautification and other work, and cause rework. At the same time, the dust and smoke generated during the polishing and painting construction process will cause varying degrees of damage to the environment and the debugged electronic equipment. In order to solve the above problems, some cable holes can be reserved in advance to meet the needs of adding equipment later. However, if cable holes are reserved in the open deck area, after the cable is installed later, due to the gap between the cable and the cable hole, rainwater will flow into the hull through the cable hole in rainy weather, thereby causing damage to the hull and equipment.

[0003] Therefore, a manhole cable pipe and a ship are needed to solve the above problems. Utility Model Content

[0033] During the shipbuilding process, in order to facilitate the synchronous arrangement of cables when adding equipment later, and to meet the waterproof requirements, water should not enter through the reserved cable holes to cause damage to the hull and equipment. Figure 1-Figure 2 As shown, the utility model provides a manhole cable pipe. The manhole cable pipe comprises a manhole cover plate 1, a connecting pipe 2 and a waterproof curved pipe 3.

[0034] Among them, a through hole 11 is opened on the manhole cover 1, and the manhole cover 1 is configured to be installed at the cable hole of the open deck, and the through hole 11 is connected to the cable hole. The connecting pipe 2 is arranged in the vertical direction, and one end of the connecting pipe 2 is connected to the manhole cover 1, and the connecting pipe 2 is connected to the through hole 11. Specifically, the connecting pipe 2 is penetrated in the through hole 11, and the connecting pipe 2 is welded to the wall of the through hole 11. The waterproof elbow 3 is in an arc shape, and one end of the waterproof elbow 3 is fixedly connected to the end of the connecting pipe 2 away from the manhole cover 1, the waterproof elbow 3 and the connecting pipe 2 are connected to each other, and the outlet end of the waterproof elbow 3 faces the open deck.

[0035] Through the above arrangement, a passage for installing cables is formed by using the through hole 11, the connecting pipe 2 and the waterproof elbow 3, which is convenient for arranging cables according to actual needs. The outlet end of the waterproof elbow 3 is arranged downward, so as to prevent water from entering the hull through the waterproof elbow 3, meet the waterproof requirements, and avoid water from causing damage to the hull and equipment.

[0036] Furthermore, a connecting assembly is provided on the manhole cover plate 1, and the manhole cover plate 1 can be connected to the open deck through the connecting assembly. By providing the connecting assembly, it is convenient for the manhole cover plate 1 to be installed and fixed on the open deck.

[0037] Furthermore, the connection assembly includes a plurality of bolts, and a plurality of connection holes 12 are provided at intervals along the circumference of the manhole cover plate 1, and the plurality of bolts are arranged in a one-to-one correspondence with the plurality of connection holes 12, and the bolts pass through the connection holes 12 and are screwed to the threaded holes on the open deck. Specifically, a plurality of threaded holes are provided at intervals along the circumference of the cable hole on the open deck, and the threaded holes are provided in a one-to-one correspondence with the connection holes 12, and the bolts pass through the connection holes 12 and are screwed to the threaded holes, so that the manhole cover plate 1 can be quickly installed on the open deck. During the construction process, if the installation of the manhole cable pipe occupies space and causes inconvenience in construction, a manhole sealing plate can be installed at the cable hole, and the manhole sealing plate can be removed and the manhole cable pipe can be installed when the cable is subsequently arranged. The bolt connection method is adopted to facilitate the installation and removal of the manhole cable pipe. In other embodiments, a clamping or riveting method can also be adopted, and the manhole cover plate 1 can also be directly welded to the open deck, and no excessive restrictions are made here.

[0038] Furthermore, a sealing ring 6 is provided on the side of the manhole cover plate 1 facing away from the connecting pipe 2. By providing the sealing ring 6, when the manhole cover plate 1 is installed on the open deck, the elastic deformation of the sealing ring 6 can be used to seal the gap between the open deck and the manhole cover plate 1, thereby further improving the sealing performance and eliminating the risk of water entering the hull through the gap between the open deck and the manhole cover plate 1.

[0039] Furthermore, a mounting groove is provided on the side of the manhole cover plate 1 away from the connecting pipe 2, and the sealing ring 6 is embedded in the mounting groove, and the sealing ring 6 protrudes relative to the mounting groove. The mounting groove is provided to facilitate the installation and positioning of the sealing ring 6.

[0040] Furthermore, a reinforcing structure 5 is provided between the manhole cover plate 1 and the connecting pipe 2, and the reinforcing structure 5 is used to improve the connection strength between the manhole cover plate 1 and the connecting pipe 2.

By providing the reinforcing elbow plate 51, the connection strength between the manhole cover plate 1 and the connecting pipe 2 can be improved, so that the connecting pipe 2 can be effectively fixed to prevent the connecting pipe 2 from being separated from the manhole cover plate 1 under the action of external force.

[0041] Furthermore, the manhole cable pipe also includes a blocking cover 4, which is arranged at the outlet end of the waterproof elbow 3. When the cable is not laid, the waterproof elbow 3 is blocked by the blocking cover 4, so that the water tightness of the manhole cable pipe can be further improved. When laying the cable, the blocking cover 4 only needs to be removed.

[0042] Furthermore, the materials of the manhole cover plate 1, the connecting pipe 2 and the waterproof elbow 3 are all stainless steel. Since the operating environment of the ship is relatively harsh, metal is easily corroded. By using stainless steel to manufacture the manhole cable pipe, the manhole cable pipe can be prevented from rusting, thereby increasing the service life of the manhole cable pipe. In other embodiments, anti-rust paint can also be applied on the surface of the manhole cable pipe, and no excessive restrictions are made here.

[0043] Further, a handle 13 is provided on the manhole cover plate 1, and the handle 13 is in a "X" shape, and the handle 13 can rotate relative to the manhole cover plate 1. By providing the handle 13, when the manhole cover plate 1 is installed, it is convenient to carry the manhole cover plate 1.

[0044] This embodiment also provides a ship, including a hull and the above manhole cable pipe, the manhole cable pipe is installed on the open deck of the hull, which is convenient for adding cables and can meet the waterproof requirements to prevent water from damaging the hull and equipment.
