The connecting frame 2 is made of aluminum alloy, which can be conveniently welded to the bulkhead or deck of the hull, reducing the difficulty of operation. The heat insulation component 4 is laid on the back-fire side or the fire-facing side of the connecting frame 2, forming a single-sided laying or double-sided laying, effectively avoiding the influence of heat on the connecting frame 2, and improving the overall heat insulation performance.

[0035] In one embodiment of the present invention, the fireproof component 14 includes an expandable fireproof sleeve and an expandable fireproof belt. A fireproof cavity is provided in the cable frame 1. The expandable fireproof sleeve and the expandable fireproof belt are evenly filled in the fireproof cavity to form a barrier layer, and both sides of the barrier layer are connected to the sealing layer 15.

[0036] Specifically, the cable 13 is passed through the threading hole 11 of the cable frame 1, and the expandable fireproof sleeve and the expandable fireproof belt are evenly filled in the fireproof cavity. When the expandable fireproof sleeve and the expandable fireproof belt encounter fire, they will expand to form a barrier layer to prevent the spread of flames.

[0039] In one embodiment of the present invention, the thickness of the sealing layer 15 is 10-20 mm. The sealing layer 15 is made of marine fireproof sealant. Waterproof sealing is achieved by evenly applying the marine waterproof sealant to the cable frame 1 and the gap between the cable line 13 and the cable frame 1.

[0040] Specifically, the marine waterproof sealant is evenly applied to both sides of the cable frame 1 so that the marine waterproof sealant can waterproofly seal the gap between the cable line 13 and the cable frame 1. The marine waterproof sealant is used for the cable line 13 to pass through both ends of the cable frame 1. The thickness of the sealing layer 15 is 10-20 mm, so that an excellent sealing layer 15 is formed to ensure the watertight and airtight performance of the entire device. The sealing layer 15 material has fire retardant properties and cooperates with the casing to form a fire barrier layer.

[0041] In one embodiment of the present invention, the connecting frame 2 includes a support plate 21 and a connecting plate 22. The support plate 21 is fixedly connected to the cable frame 1. The connecting plate 22 is vertically arranged on the support plate 21. The free end of the connecting plate 22 is connected to the hull aluminum frame 23.

The support plate 21 and the connecting plate 22 are both made of aluminum alloy for hull structure.

[0043] Specifically, the support plate 21 and the connecting plate 22 are welded together. After the support plate 21 is connected to the cable frame 1, the connecting plate 22 is welded together with the hull aluminum frame 23. Since the support plate 21 and the connecting plate 22 are both made of aluminum alloy for hull structure, it is preferred that they adopt general strength aluminum alloy for hull structure, and the hull aluminum frame 23 adopts core aluminum plate with a thickness of 4-8mm. The use of aluminum structure not only makes it convenient to weld the device to the bulkhead or deck of the hull, but also brings higher sailing speed and better maneuverability to the hull and increases the load capacity, thereby improving the economy and environmental friendliness of long-distance sailing.

[0044] In one embodiment of the present invention, the thickness of the support plate 21 is 6-15 mm, the thickness of the connecting plate 22 is 4-9 mm, and the thickness of the hull aluminum frame 23 is 5-10 mm.

[0045] Specifically, the use of aluminum facilitates welding the device to the bulkhead or deck of the ship. Preferably, the support plate 21 is 8 mm thick, and the connecting plate 22 is 5 mm thick. This thinness and good ductility allow for a certain amount of expansion margin when heated, ensuring the stability of the entire device and meeting the ship's protection requirements. The hull aluminum frame 23 is 6 mm thick. Using aluminum of these specifications not only ensures sealing and strength, but also ensures welding stability.

[0046] In one embodiment of the present invention, the heat insulation component 4 includes a first heat insulation plate 41 and a second heat insulation plate 43 connected to each other, the first heat insulation plate 41 is arranged on the connecting plate 22, and an avoidance groove 42 is opened on the first heat insulation plate 41, and the avoidance groove 42 is located at the connection between the connecting plate 22 and the hull aluminum frame 23, the second heat insulation plate 43 is arranged on the support plate 21, and a heat insulation baffle 44 is provided on the free end of the second heat insulation plate 43, and the heat insulation baffle 44 and the second heat insulation plate 43 are covered on the support plate 21.

[0047] Specifically, the first heat insulation plate 41 is arranged on the connecting plate 22, which can fully cover the connection between the connecting plate 22 and the hull aluminum frame 23, effectively blocking the heat. At the same time, an avoidance groove 42 is opened on the first heat insulation plate 41, and the avoidance groove 42 is located at the connection between the connecting plate 22 and the hull aluminum frame 23, so that it can be better laid on the connecting frame 2; the second heat insulation plate 43 is arranged on the support plate 21, and the heat insulation baffle 44 and the second heat insulation plate 43 are covered on the support plate 21, and a heat insulation groove 45 is formed between the two and is covered on the support plate 21, effectively avoiding the influence of heat on the support plate 21, and at the same time, the free end of the heat insulation baffle 44 extends a distance, so that it covers a distance on the sealing layer 15, thereby improving the overall heat insulation performance.

[0048] In one embodiment of the present invention, the thickness of the first heat insulation board 41, the second heat insulation board 43 and the heat insulation baffle 44 is 40-60 mm, and the first heat insulation board 41, the second heat insulation board 43 and the heat insulation baffle 44 are all made of non-combustible materials with a density of 70 kg / m 3 .

[0049] Specifically, since the connecting frame 2 and the hull aluminum frame 23 are made of aluminum alloy, which is relatively special and has a low melting point, both the bulkhead and the deck of the hull need insulation materials to face the fire. The thickness of the first insulation board 41, the second insulation board 43 and the insulation baffle 44 is 40-60 mm, which can ensure the insulation of the heat from the fire surface to prevent the aluminum alloy from melting. At the same time, the first insulation board 41, the second insulation board 43 and the insulation baffle 44 are all made of non-combustible materials with a density of 70 kg / m 3, the heat insulation component 4 can be better laid on the connecting frame 2, ensuring the reliability and safety of the sealing system.

[0050] Usage process

[0051] The cable 13 is passed through the threading hole 11 of the cable frame 1, and the expansion fireproof sleeve and the expansion fireproof belt are evenly filled in the fireproof cavity. The expansion fireproof sleeve and the expansion fireproof belt will expand to form a barrier layer when encountering fire, preventing the spread of flames, and are suitable for use in areas with high fire protection requirements; then the marine waterproof sealant is evenly applied to both sides of the cable frame 1, so that the marine waterproof sealant can waterproof and seal the gap between the cable 13 and the cable frame 1, and it is used for the cable 13 passing through both ends of the cable frame 1. The thickness of the sealing layer 15 is 10-20mm, so that it forms an excellent sealing layer 15 to ensure the watertight and airtight performance of the entire device, and the sealing layer 15 material It has fire-retardant properties and cooperates with the casing to form a fire barrier layer. The support plate 21 and the connecting plate 22 are welded together. After the support plate 21 is connected to the cable frame 1, the connecting plate 22 is welded together with the hull aluminum frame 23. Since the support plate 21 and the connecting plate 22 are made of aluminum alloy for hull structure, it is preferred that the general strength hull structure aluminum alloy is used. The hull aluminum frame 23 adopts a core aluminum plate with a thickness of 4-8mm. The use of aluminum structure not only makes it convenient to weld the device to the bulkhead or deck of the hull, but also brings a higher sailing speed and better maneuverability to the hull and increases the load capacity, thereby improving the economy and environmental friendliness of long-distance sailing.
