[0001] The utility model relates to shipbuilding technical field, especially a kind of ship emergency cable arrangement system. BACKGROUND
[0002] In the process of ship design and construction, cabling is a key engineering. Especially for the cabling of cables, classification societies usually have strict requirements to ensure the safety and reliability of the ship in emergency situations. According to the regulations of classification societies, cables in non-machinery space should not pass through the machinery space to avoid the influence of machinery space fire or high temperature on the normal operation of emergency systems in the event of fire or other emergencies.
[0003] However, in some ships, such as double island type container ships or small and medium sized container ships, there is often a conflict between the location of the machinery space and the cabling requirements. In these ship types, the emergency generator room is usually located at the stern, while the superstructure is located in the middle or front of the ship, resulting in the need for cables to pass through from the stern to the bow.
[0004] In order to meet the requirements of cable cabling and machinery space separation, two solutions are usually adopted in the prior art: one is to open additional holes on the deck to route the cables along the side walkways to avoid the machinery space; the other is to set up an isolated empty cabin between the machinery space and the main deck to ensure effective separation of the cables and the machinery space. However, by opening holes on the deck, due to the limitations of stacking and safety passages, it is not possible to effectively avoid the machinery space; while by setting up an isolated empty cabin, although the isolation of cables and machinery space can be achieved, it will increase the structural complexity and weight of the ship, and still face challenges in fireproofing and insulation.

[0024] In some ships, such as twin island type container ships or small and medium-sized container ships, the emergency generator room is usually arranged at the stern, while the superstructure is located in the middle or front part of the ship, which leads to the need for cables to pass through from the stern to the bow of the ship. In order to meet the requirements of cable routing and separation from the engine room, two solutions are usually adopted in the prior art: one is to additionally open holes on the deck to route the cables along the side walkways to avoid the engine room; the other is to set up an isolated empty cabin between the engine room and the main deck to ensure the effective separation of the cables from the engine room. However, by the way of opening holes on the deck, due to the limitation of container stacking and safety passage, the engine room cannot be ideally avoided; and by the way of setting up an isolated empty cabin, although the isolation of the cables from the engine room can be achieved, the structural complexity and weight of the ship are increased.
[0025] The present embodiment provides a ship emergency cable arrangement system which can make the cables pass through smoothly without increasing new isolated cabins and can meet the safety regulations of the classification society.
[0026] Please refer to Figure 1 The ship emergency cable arrangement system 100 in the present embodiment includes a ship body 10, cables 20 and a cable isolation box 30.
[0027] The ship body 10 includes an engine room 11 arranged at the stern thereof, an emergency power generation room 13 arranged above the engine room 11, a main deck arranged at the waist of the ship body 10, a side walkway 12 located below the main deck, and a superstructure arranged on the main deck.
[0028] The cables 20 are electrically connected to the emergency power generation room 13 at one end, pass through the engine room 11 to the side walkway 12, and extend along the side walkway 12 to be electrically connected to the superstructure to provide emergency power supply to the superstructure. The cable isolation box 30 is fixed on the inner wall of the engine room 11 and separates the cables 20 passing through the engine room 11 from the engine room 11.
[0029] Specifically, the main deck of the ship body 10 is located in the middle of the ship and is the largest and most important deck on the ship. A plurality of stacked containers 40 are arranged on the main deck of the ship body 10, and the containers 40 are vertically stacked in the cargo area of the main deck. The side walkway 12 is located directly below the main deck and extends along the length direction of the ship body 10. The side walkway 12 is designed to be spacious and easy to pass through, facilitating the quick movement of the crew in emergency situations, and allowing the crew to conduct inspection, maintenance and emergency operation inside the ship body 10.
[0030] The engine room 11 is located at the stern of the ship body 10 and is arranged behind the side walkway 12. The engine room 11 is the core area of the ship power system, and the main propulsion equipment and auxiliary mechanical equipment, such as fuel propulsion system, cooling system and ventilation system, are arranged inside the engine room 11.
[0031] The emergency power room 13 is located directly above the engine room 11, and the emergency power generator 131 and the emergency power distribution system are installed in the emergency power room 13, which can provide necessary power supply for the power equipment of the superstructure of the ship when the main power generation system fails or the ship encounters an emergency.
[0032] The superstructure is a structure arranged on the main deck, which usually includes spaces such as the bridge, control room, navigation equipment, living area and communication facilities of the ship. That is, the superstructure provides the main space for the crew to work and live, and a large number of electrical equipment and control systems are arranged inside, which need to be connected with the emergency power room 13 through the cable 20 to ensure that the key equipment of the superstructure can operate normally in an emergency.
[0033] Based on the above arrangement structure of the double-island type container ship 40, the main deck is stacked with containers 40, which will cause the cable 20 of the emergency power room 13 to be unable to directly penetrate from the main deck into the side walkway 12, but needs to penetrate into the side walkway 12 through the engine room 11 and then be connected with the superstructure.
[0034] Therefore, in the embodiment, the cable isolation box 30 is directly fixed on the inner wall of the engine room 11, so that a special cabin is not needed to be arranged in the engine room 11 to isolate the emergency cable 20, thereby reducing the overall weight of the ship body 10 and helping to improve the fuel efficiency and load capacity of the ship. Moreover, the arrangement of the cable isolation box 30 can also reduce the safety hazards of the cable 20 in the engine room 11 caused by high temperature, fire or other faults, ensure the safety of the emergency power supply line, meet the relevant requirements of the classification society, and improve the emergency response capability of the ship in an emergency.
[0035] Please refer to Figure 1 In some embodiments, the ship body 10 further includes an isolation cabin 14. The isolation cabin 14 is located between the emergency power room 13 and the engine room 11, and separates the engine room 11 from the emergency power room 13.
[0036] Specifically, the isolation cabin 14 is located between the emergency power room 13 and the engine room 11, and effectively separates the engine room 11 from the emergency power room 13, so that it can effectively block the possible transmission of danger between the engine room 11 and the emergency power room 13 in an emergency. For example, when a fire or a leakage accident occurs in the engine room 11, the isolation cabin 14 can prevent the spread of fire or harmful gas to the emergency power room 13, thereby ensuring the normal operation of the emergency power system and ensuring the uninterrupted emergency power supply, so as to improve the overall safety of the ship body 10,
[0037] In some embodiments, the ship body 10 further includes a rudder cabin 15 for controlling the direction of the ship. The rudder cabin 15 is arranged at the stern of the ship body 10 and is isolated from the engine room 11 and the isolation cabin 14.
[0038] The rudder cabin 15 is mainly used for controlling the sailing direction of the ship, and is close to the propulsion system of the ship, so that the rudder can directly control the direction change of the ship. The rudder cabin 15 is separated from the engine room 11 and the isolation cabin 14, so as to prevent the high temperature, vibration or other adverse factors generated by the engine room 11 from affecting the rudder cabin 15, thereby ensuring the working reliability of the rudder system.
[0039] In some embodiments, the emergency power room 13 is provided with an emergency generator 131 and an emergency distribution board 132. The emergency generator 131 is electrically connected with the emergency distribution board 132, one end of the cable 20 is electrically connected with the emergency distribution board 132, and the other end is electrically connected with the superstructure, so as to output power to the superstructure.
[0040] The emergency distribution board 132 is electrically connected with the emergency generator 131 and the cable 20, so that the current generated by the emergency generator 131 is transmitted to the superstructure area of the ship through the circuit breaker, switch or control device on the emergency distribution board 132 and the cable 20, so as to realize emergency power supply to the superstructure.
[0041] In some embodiments, the emergency distribution board 132 can be located on one side of the emergency power room 13 close to the cable isolation box 30. That is, the emergency distribution board 132 is arranged close to the cable isolation box 30, which can shorten the length of the cable 20 from the distribution board to the cable isolation box 30, reduce the exposed part of the cable 20 in the emergency power room 13, and thereby reduce the risk of cable 20 failure caused by mechanical damage, overheating or other environmental factors.
[0042] Please refer to Figure 1 In some embodiments, the cable isolation box 30 is fixed on the top wall of the engine room 11 facing the emergency power room 13 and the side wall facing one side of the side walkway 12. The cable isolation box 30 and the top wall and the side wall of the engine room 11 form a containing cavity for accommodating the cable 20 passing through the engine room 11, so as to separate the cable 20 from the engine room 11.
[0043] Specifically, the cable isolation box 30 can be a semi-closed box structure; after the cable 20 passes through the engine room 11, the cable isolation box 30 is welded with the inner wall of the engine room 11, so that the cable isolation box 30 and the inner side wall of the engine room 11 form an integrated structure, so as to completely separate the cable 20 from the internal space of the engine room 11. It is conceivable that the specific structure of the cable isolation box 30 can be adjusted according to the inner wall of the engine room 11 or the actual environment, as long as it can form a closed containing cavity with the inner wall of the engine room 11.
[0044] In some embodiments, the top wall of the machinery room 11 is provided with a first through-hole for the cable 20 to pass into the accommodation cavity inside the cable isolation box 30. The side wall of the machinery room 11 is provided with a second through-hole, which communicates the accommodation cavity with the side walkway 12, so that the cable 20 in the accommodation cavity can pass into the side walkway 12.
[0045] Specifically, the first through-hole is provided on the top wall of the machinery room 11 and communicates the accommodation cavity of the cable isolation box 30 with the isolation cabin 14, so that the cable 20 passing through the isolation cabin 14 can pass into the accommodation cavity formed by the cable isolation box 30 and the machinery room 11. The second through-hole is provided on the side wall of the machinery room 11 close to the side walkway 12, so that the cable 20 can smoothly pass out of the accommodation cavity to the side walkway 12 and then be electrically connected with the superstructure.
[0046] In some embodiments, the distance between the first through-hole and the second through-hole can be relatively close, so that the length of the cable 20 passing through the machinery room 11 is shorter, thereby reducing the volume of the cable isolation box 30.
[0047] In some embodiments, each of the first through-hole and the second through-hole is provided with a cable penetrating piece 31, and each cable penetrating piece 31 is provided with a plurality of holes for the passage of the cable 20.
[0048] The cable penetrating piece 31 is usually made of high-strength insulating materials, such as high-temperature-resistant and corrosion-resistant rubber, plastic or composite materials. These materials can provide effective mechanical protection to prevent the cable 20 from being damaged due to wear, cutting or other environmental factors. The cable penetrating piece 31 has a plurality of holes, each of which can accommodate one or more cables 20, so that the cables 20 can be managed centrally to reduce chaos. Moreover, the plurality of holes can also allow different specifications and types of cables 20 to pass through at the same time to adapt to various complex cable 20 wiring requirements.
[0049] In some embodiments, the inner side of the accommodation cavity formed by the cable isolation box 30 and the inner wall of the machinery room 11 is provided with an insulating fireproof layer.
[0050] The insulating fireproof layer is made of high-performance fire-resistant materials, such as refractory fibers, ceramic fiber boards, aluminum silicate fibers and other specially treated composite materials, which can maintain structural stability for a long time in high-temperature environments, prevent short circuits or electrical leakage of the cable 20, and cause impact on the interior of the machinery room 11, thereby greatly enhancing the safety and reliability of the system.
[0051] Moreover, the thickness of the insulating fireproof layer can be adjusted according to the wiring requirements of the emergency cable 20 and the fireproof grade requirements of the ship to ensure that sufficient protection is still provided under extreme conditions, ensuring that the emergency cable 20 can work normally under any condition during the operation of the ship, protecting the safety of the crew and the ship.
[0052] Of course, in some other examples, an insulating fireproof layer may also be provided on the outer surface of the cable isolation box 30 to further improve the isolation protection capability of the cable isolation box 30 to meet the requirements of the shipping company.
[0053] In summary, the ship emergency cable arrangement system 100 of this embodiment, by providing a cable isolation box 30 within the engine room 11, completely isolates the emergency cable 20 passing through the engine room 11 from the space of the engine room 11. This reduces the potential safety hazards of the cable 20 within the engine room 11 due to high temperature, fire, or other failures, ensures the safety of the emergency power supply line, meets the relevant requirements of the classification society, and enhances the emergency response capability of the ship in an emergency. Furthermore, by directly fixing the cable isolation box 30 to the inner wall of the engine room 11, there is no need to provide a cabin within the hull 10, thereby reducing the overall weight of the hull 10 and helping to improve the fuel efficiency and load capacity of the ship.
[0054] While the present invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope of the appended claims. Therefore, all changes and modifications that fall within the scope of the claims or their equivalents are intended to be covered by the appended claims.
