Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a sealing structure of a tubular cable penetration sealing type. Background Art

[0002] The ship's cables run through the entire ship, providing power and control signals for the equipment on board. When the cables pass through the decks and bulkheads, it is inevitable to open holes for the cables to pass through. Due to the high fire protection requirements of ships, when ship cables pass through bulkheads, decks and other structures, in order to prevent the spread of flames and seal the openings, fire-resistant plugging materials are conventionally used to seal the cable penetrations. This solution is to mix powder and auxiliary liquid in a certain ratio before use. If the workers do not mix the proportions properly, there is a high possibility that the plugging materials in the penetrations will crack in the later stage. After the plugging materials are poured, the plugging materials in the cable penetrations will harden. When there is a need to replace or add cables in the later stage, the corresponding cable penetration plugging materials must be manually chiseled open, which is time-consuming and labor-intensive. Any improper operation during the process can easily cause cable damage. Utility Model Content

[0003] The utility model aims to provide a sealing structure of a tubular cable penetration sealing type in view of the defects and shortcomings of the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a sealing structure of a tubular cable penetration sealing type, the innovation of which lies in: comprising a cable penetration piece, the cable penetration piece is a hollow structure, and is arranged through a bulkhead or a deck, a plurality of cables are arranged inside the cable penetration piece, a plurality of fireproof cable sleeves are arranged inside the cable penetration piece, the fireproof cable sleeves are split in the middle and are wrapped around the cables in the cable penetration piece, and the left and right openings of the cable penetration piece are filled with fireproof sealant.

[0005] Furthermore, the shape of the cable penetration piece includes round, square, and oval, and the length is 250 mm.

[0006] Furthermore, a plurality of spare cable sleeves are pre-buried inside the cable penetration piece.

[0007] After adopting the above structure, the utility model has the following beneficial effects:

[0008] 1. The utility model has a simple design and follows the design standard of the cable penetration parts of the shipyard. The cable penetration parts are easy to select and the shipyard can make them by itself, saving the cost of shipbuilding. At the same time, it is not necessary to arrange the cables of each cable penetration part in advance.

[0009] 2. The utility model is more convenient and quick to add or replace cables in the later stage. Partial replacement will not affect the structure of the cable penetration parts and other cables. It is easy to operate and easy to construct. It can be learned immediately without complicated operation training for workers.

[0010] 3. The utility model adopts the combined action of fireproof cable casing and fireproof sealant to form a heat-insulating fireproof layer, which can effectively prevent heat conduction and thus play a fireproof role. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] 1 cable penetration, 2 bulkhead or deck, 3 cable, 4 fireproof cable casing, 5 fireproof sealant, 6 spare cable casing. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and are not used to limit the utility model.

[0016] See also Figure 1 A sealing structure of a tubular cable penetration sealing type includes a cable penetration piece 1. The cable penetration piece 1 is a hollow structure and is set through a bulkhead or a deck 2. A plurality of cables 3 are set through the cable penetration piece 1. A plurality of fireproof cable sleeves 4 are set inside the cable penetration piece 1. The fireproof cable sleeves 4 are split in the middle and wrapped around the cables 3 in the cable penetration piece. The left and right openings of the cable penetration piece 1 are filled with fireproof sealant 5. Specifically, the utility model adopts a fireproof cable sleeve 4 and a fireproof sealant 5 to seal the cable of the cable penetration; the fireproof cable sleeve 4 is about 210mm long and is split in the middle. When in use, it is wrapped around the cable in the penetration. The sleeve of appropriate diameter can be selected according to the outer diameter of the cable to ensure that the sleeve can completely wrap the cable; the fireproof sealant 5 is used to seal the two ends of the cable penetration 1, and each end can be about 20mm thick. Under the combined action of the fireproof sleeve and the fireproof sealant, a heat-insulating and fire-proof layer is formed, which can effectively prevent heat conduction and thus play a fire-proof role; when adding or replacing cables at a later stage, it is only necessary to partially remove the fireproof sealant 5 to achieve the addition or replacement, which is convenient and quick to operate, and the partial replacement will not affect the structure of the cable penetration and other cables, and the operation is simple.

[0017] In this embodiment, the cable penetration piece 1 has a shape including round, square, and oval, and a length of 250 mm. The cable penetration piece 1 adopts a conventional type of self-made penetration piece of the shipyard, which is simple and convenient to manufacture and has low cost; its shape is roughly divided into round, square, and oval, but it is not limited to the above three shapes, and can be selected according to the needs of each site; the length of the penetration piece is consistent with the shipyard standard, and a length of 250 mm can be manufactured.

[0018] In this embodiment, a plurality of spare cable sleeves 6 are pre-buried inside the cable penetration piece 1, which can be used when needed, which is convenient and quick; the gaps in the cable penetration piece 1 are filled with spare cable sleeves 6 to fill the cable penetration piece 1.

[0019] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
