Description

Technical Field

[0001] This invention belongs to the field of passenger roll-on / roll-off ship technology, specifically a new energy passenger roll-on / roll-off ship for inland waterways that carries new energy vehicles. Background Technology

[0002] Preliminary market research on gasoline and new energy vehicles shows that gasoline vehicles account for 55.86% of the market, while new energy vehicles account for 44.14%, almost half of the market share. Under the guidance of national policies, the development speed of new energy vehicles will be even faster. At the same time, a survey conducted in highway service areas found that the proportion of new energy freight vehicles in all freight vehicles has reached a new high, showing a rapid development trend.

[0003] The development of various new energy vehicles on land (including pure electric vehicles, hybrid vehicles, hydrogen fuel cell vehicles, and LNG-powered vehicles) is booming; the development and actual operation of various new energy vessels for water transport are also progressing rapidly; among them, the demand for passenger ro-ro ships carrying new energy vehicles has increased significantly. Based on this, it is urgent to develop a new structure that meets safety requirements for new energy passenger ro-ro ships carrying new energy vehicles, and to provide a safe solution for such ships. New energy passenger ro-ro ships carrying new energy vehicles represent a completely new field in the historical development process, and there are no mature precedents to draw upon.

[0004] Among them, the domestic inland river and Three Gorges Reservoir area passenger ro-ro ship market, which has been developing for more than 20 years, is still in a state of flux regarding the transport of new energy vehicles. As mentioned above, how to meet the safe transport conditions for new energy vehicles on passenger ro-ro ships and help the passenger ro-ro ship market meet the growing demand for new energy vehicles to travel on passenger ro-ro ships is an inevitable direction.

[0005] In the development of inland river passenger roll-on / roll-off (Ro-Ro) ships, the framework of the upper deck above the vehicle area is generally composed of ordinary crossbeams or deck longitudinals plus strong crossbeams and deck longitudinal girder structures. In particular, the strong crossbeams and deck longitudinal girder have considerable height. These tall strong crossbeams and deck longitudinal girder form deep inverted recesses on the upper deck above the vehicle area. Assuming that new energy vehicles such as pure electric vehicles, hybrid vehicles, hydrogen fuel cell vehicles, and LNG-powered vehicles leak gas into these inverted recesses, the dense arrangement of pipes and numerous cables beneath the upper deck creates complex obstructions, making it difficult to use convenient, effective, and rapid ventilation methods to expel the gas. Furthermore, there are numerous cables beneath the upper deck, such as main cables, cables for monitoring equipment, and cables for alarm and camera equipment. In the event of a fire, if flammable gases accumulate in these inverted recesses, they may form gasbags, increasing the safety risk of fire and explosion. In addition, the numerous cables on the upper deck can also cause secondary damage if exposed to fire, further endangering the safety of the ship and the lives and property of personnel. Therefore, it is necessary to develop a structure without these inverted recesses to avoid the accumulation of flammable gases.

[0006] Furthermore, the decks above the vehicle-carrying areas of passenger roll-on / roll-off ships are all single-level decks. According to design convention, this deck is generally designed as passenger cabins and public areas, where the density of people is high, making it a key area requiring protection. In the event of a fire or explosion, the single-level deck provides limited protection against further damage to the cabins caused by the fire or explosion. Ensuring the safety of these areas requires the development of a new structure.

[0007] In addition, the Yangtze River Navigation Administration of the Ministry of Transport has issued a notice requiring passenger and roll-on / roll-off (Ro-Ro) ships on the Yangtze River and in the Three Gorges Reservoir area to meet specific requirements for the convenience and safety of loading Ro-Ro vehicles. Specifically, Ro-Ro passenger and roll-on / roll-off (Ro-Ro) ships that load cargo vehicles on inland waterways should be equipped with a large-span portal structure and should not have supporting columns in the middle.

[0008] Current regulations and standards require that when loading vehicles onto passenger roll-on / roll-off ships, there should be a 300mm longitudinal clearance between vehicles, a 700mm lateral passage between every four vehicles, and a 500mm longitudinal passage between vehicles in the left and right directions. There should also be an 850mm longitudinal passage between vehicles and the sides of the ship.

[0009] When loading new energy vehicles, frequent inspections are required. In case of fire hazards, in addition to automatic fire control, manual firefighting with portable equipment is necessary for immediate suppression. The current vehicle arrangement and passageway layout, with a width of only 300mm laterally, makes it difficult for firefighters to enter between any individual vehicles, failing to meet this essential requirement. Therefore, the vehicle arrangement and passageway layout in the new energy vehicle loading area require new standards for the longitudinal and transverse widths of the passageways in the development of passenger roll-on / roll-off ships. This is to facilitate inspections and extinguish fires in their early stages, thereby ensuring the safety of new energy passenger roll-on / roll-off ships carrying new energy vehicles and the lives and property of passengers.

[0010] In summary, existing technical solutions for adapting inland river passenger ro-ro ships (especially those on the Sichuan River and in the Three Gorges Reservoir area) to carry new energy vehicles are immature. The market in this region is still blank and there are no mature precedents to learn from, resulting in many safety and compatibility defects: the reverse indentation formed by the deck frame above the vehicle area, combined with the obstruction of dense pipelines and cables below, makes it difficult for flammable gases leaked from new energy vehicles to be discharged in time, easily accumulating and forming gasbags, increasing the risk of fire and explosion. Moreover, the cables will cause secondary damage when exposed to fire, endangering the safety of the ship and personnel; the single-layer deck above the vehicle area, as a densely populated passenger cabin and public area, has insufficient isolation and resistance to fire and explosion, and cannot effectively protect the safety of the passenger cabin; although passenger ro-ro ships on the Sichuan River and in the Three Gorges Reservoir area need to meet the requirements of large-span portal frame and no intermediate support columns, the current regulations on vehicle arrangement and passage standards cannot meet the needs of new energy vehicle inspection and initial fire fighting, making it difficult for firefighters to enter the vehicle compartment for work, and the existing structural and design standards cannot adapt to the loading needs of the rapidly developing new energy vehicles.

[0011] Furthermore, current conventional fire control measures for passenger roll-on / roll-off ships primarily rely on traditional fire extinguishing methods such as water-based fire suppression, foam fire suppression, and carbon dioxide fire suppression. However, for new energy vehicles, especially electric vehicles equipped with lithium batteries, the main cause of spontaneous combustion and deflagration is battery thermal runaway, which is difficult to extinguish using conventional fire suppression methods. Recently, the industry has developed a method for extinguishing fires in new energy vehicles using fire blankets for physical isolation, which is superior to traditional fire suppression methods.

[0012] However, in reality, the loading area of ​​passenger roll-on / roll-off ships is densely packed with vehicles, making it difficult to implement the method of manually covering the vehicles with fire blankets due to the narrow passageways. This is mainly because the cargo vehicles carrying new energy vehicles are tall, and the large size and weight of the fire blankets make it difficult to cover the entire vehicle with fire blankets for fire extinguishing, which is also difficult to do manually.

[0013] Based on this, a method is needed to automatically deliver fire blankets to new energy vehicles requiring fire control. This requires the development of specialized equipment. Summary of the Invention

[0021] In a preferred embodiment, the isolated cabin layer includes an upper deck bottom plate located at the top layer. The bottom of the upper deck bottom plate is fixed to the top plate by strong crossbeams, strong longitudinal girder and ordinary deck longitudinal ribs, thereby forming a large-span box-type sheet structure.

[0022] In a preferred embodiment, the partition top plate is made of A60 fire-resistant partition board; The lower surface of the partition roof forms the ceiling of the vehicle carrying area and adopts a complete planar structure; The height of the partition top plate must be at least 900mm; The spacing between the strong crossbeams shall not exceed 3m.

[0023] In a preferred embodiment, the corner where the large-span box-type sheet structure connects to the transition sidewall of the hull adopts a box-shaped arc structure for transition; The side transition wall and the large-span box-type sheet structure are connected by a circular arc transition to form a large-span portal structure.

[0024] In a preferred embodiment, the vehicle loading area includes a fuel vehicle loading area, a natural gas vehicle loading area, an electric vehicle loading area, and a hydrogen fuel cell vehicle loading area; Vehicle layout and passageway design in the vehicle carrying area: The vehicle width is designed to be 2.7m, with a transverse passageway of at least 1.5m at the front and rear ends; the longitudinal passageway width between vehicles in the left and right directions is at least 700mm; the transverse passageway width in the front and rear directions is at least 1000mm; the distance between the inner walls of the two sides above the main deck and the vehicles is at least 1000mm; in this way, independent longitudinal and transverse passageways are formed between all vehicles, and all passageways are connected, providing immediate access to each individual vehicle for inspection.

[0029] The present invention has the following beneficial effects: 1. The passenger roll-on / roll-off ship of this invention can be used for the safe transportation of new energy vehicles on inland waterways, effectively preventing the risk of fire or explosion during the transportation of new energy vehicles, and ensuring the safety of vehicle transportation and passenger travel; while ensuring its structural strength, it facilitates vehicle loading; at the same time, it facilitates safety inspections during subsequent vehicle transportation, and meets the relevant design specifications.

[0030] 2. This invention achieves the goal of green and environmental protection by using new energy power devices, and provides electricity by generating electricity through solar panels.

[0031] 3. This invention can generate electricity by using a single methanol fuel generator, thereby providing power to the electric motor. In addition, the use of methanol fuel has an environmental protection effect.

[0032] 4. Through the structural design of the isolated air chamber layer, the bottom of which is a flat and smooth ceiling structure, ventilation is facilitated and air circulation is facilitated, preventing the accumulation of flammable gases leaked from new energy vehicles. It can ensure that any leaked gases can be discharged in a timely manner under any circumstances, so as not to cause the risk of fire or explosion.

[0033] 5. The isolation of the empty cabin layer effectively increases the safety of the upper deck cabins and common areas. In this way, the deckhouse on the regular upper deck and the common areas at the bottom are fire-resistant separated, improving safety and providing a good explosion-proof effect.

[0034] 6. The large-span box-type sheet structure formed by setting up an isolated empty compartment layer can meet the structural strength requirements of a large span without supporting columns in the middle, thus facilitating the loading of subsequent vehicles.

[0035] 7. Box-shaped rounded transitions are used at the corners where the large-span box-type sheet structure connects to the side transition wall to eliminate corner stress.

[0036] 8. The upper deck below the upper deck is separated from the vehicle area by an A60-class partition. This ensures a safe separation between the cabins and densely packed personnel areas on the upper deck and the vehicle area.

[0037] 9. The system provides independent longitudinal and lateral passages between vehicles, all of which are interconnected, enabling immediate access to each individual vehicle for inspection and providing a solution for workers and firefighters to accurately eliminate potential hazards.

[0038] 10. By installing fireproof curtains, it is ensured that they can be quickly deployed in the event of a fire in a new energy vehicle, thereby dividing the vehicle area into multiple relatively independent zones to effectively prevent the spread of fire, thus achieving the purpose of fire suppression and ensuring safety.

[0039] 11. By setting up fireproof cover delivery tracks and equipping them with corresponding fireproof covers, it is ensured that when a local vehicle catches fire, the fireproof cover can be quickly pushed across the area to the top of the burning vehicle and cover it to prevent the spread of fire, thereby achieving the functions of fire extinguishing and fire blocking, and thus ensuring safety.

[0040] 12. By setting up a light crane and equipping it with fire blankets, it is possible to ensure that when a local vehicle catches fire, the fire blankets can be quickly moved to the burning vehicle and physically isolated, thereby achieving the effect of fire prevention and fire blocking.

[0093] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0094] Example 1: See Figure 1-31A new energy passenger roll-on / roll-off (Ro-Ro) vessel for transporting new energy vehicles includes a hull 7. The inner bottom of the hull 7 is a bilge structure, and a main deck 1 is provided on top of the bilge structure. The main deck 1 has a vehicle carrying area for loading new energy vehicles 24. An upper deck 3 is provided on top of the main deck 1, a driving deck 4 is provided on top of the upper deck 3, and a roof deck 5 is provided on top of the driving deck 4. The hull 7 is equipped with a new energy power unit for providing power. An isolation compartment layer 35 for safety protection is provided between the upper deck 3 and the lower vehicle carrying area. The isolation compartment layer 35 forms a flat and smooth ceiling without any pits above the vehicle carrying area. The top of the perforated side opening and the ceiling formed by the bottom of the isolation compartment layer 35 are in the same plane. The above-mentioned Ro-Ro vessel can be used for the safe transportation of new energy vehicles on inland waterways, effectively preventing the risk of fire or explosion during the transportation of new energy vehicles, and ensuring the safety of vehicle transportation and passenger travel. While ensuring its structural strength, it facilitates vehicle loading and subsequent safety inspections during vehicle transportation, meeting the relevant design specifications. This new energy passenger ro-ro ship achieves its green and environmentally friendly goals by adopting a new energy power unit. The structure of the isolated empty cabin layer 35, with its flat and smooth ceiling structure at the bottom, facilitates ventilation and air circulation, preventing the accumulation of flammable gases leaking from the new energy vehicle. This ensures that any leaked gases can be promptly eliminated in any situation, preventing the risk of fire or explosion.

[0095] In addition, the isolation of the empty cabin layer 35 effectively increases the safety of the upper deck cabins and common areas. In this way, the deckhouse on the conventional upper deck is separated from the common areas, achieving fire separation and improving safety.

[0096] Furthermore, the bottom structure includes a steering gear compartment 8, a fresh water compartment 10, a ballast compartment 11, a river water tank 13, a central control room 46, an engine room 14, a methanol compartment 15, a grey water compartment 16, a black water compartment 17, an empty compartment 18, a bow thruster compartment 23, a bow tip compartment 19, an anchor chain compartment 20, and a tool room 47; an isolation empty compartment 48 is provided between the methanol compartment 15 and the grey water compartment 16.

[0097] Furthermore, it also includes the battery compartment.

[0098] Furthermore, a step-changing platform 2 is provided between the main deck 1 and the upper deck 3; the main deck 1 is equipped with a cable well 25, an outdoor air conditioning unit 26, a drone platform 27, a protective equipment room 28, a methanol refueling station 29, and a reserved box-type power supply 49; through the above-mentioned structural arrangement on the main deck 1, it can meet the subsequent structural and functional requirements of the main deck.

[0099] Furthermore, the new energy power unit includes a solar panel 6 fixed to the top of the canopy deck 5. The solar panel 6 generates electricity through solar energy and supplies power to the electric motor 12. The electric motor 12 is located inside the engine room 14, and its output is connected to the propeller 9 at the stern to provide ship power. A shaft tunnel compartment 31 is provided between the engine room 14 and the steering gear compartment 8. A steering gear 32 is located inside the steering gear compartment 8, and its output is connected to the steering rudder. By adopting the above-mentioned new energy power unit, the ship can be provided with new energy power. Electricity is generated by the solar panel 6, stored in batteries, and then used to power the electric motor, thereby providing navigation power for the ship.

[0100] Furthermore, the new energy power unit also includes a generator 30 installed inside the engine compartment 14. The generator 30 is a methanol fuel generator and is connected to the methanol tank 15. The generator 30 is electrically connected to the electric motor 12 and provides electrical energy. The methanol fuel generator can generate electricity, which is then supplied to the electric motor, achieving a good environmental protection effect.

[0101] Furthermore, a plurality of fuel preparation rooms 33 are provided adjacent to the methanol tank 15; the fuel preparation rooms 33 are used to prepare for the refueling of methanol fuel.

[0102] Furthermore, the anchor chain compartment 20 is equipped with an anchor chain 21 inside. The anchor chain 21 is used for anchoring.

[0103] Furthermore, a ramp 22 is installed on the outer wall of the bow tip 19. The ramp 22 facilitates subsequent loading.

[0104] Furthermore, the isolation compartment layer 35 includes an upper deck floor 36 located at the top. The bottom of the upper deck floor 36 is fixed to the top plate 39 via strong crossbeams 37 and strong longitudinal girder 40, in conjunction with ordinary deck longitudinal ribs, thus forming a large-span box-type sheet structure. The isolation compartment layer 35 effectively isolates the vehicle area from the personnel area on the upper deck, significantly improving the safety of the personnel area and enhancing fire separation. Moreover, even in the event of a fire or explosion in the vehicle area, the isolation compartment layer 35 provides excellent isolation, buffering, and protection, ultimately ensuring the safety of the personnel area.

[0105] Furthermore, the partition top plate 39 is made of A60 fire-resistant partition board; by using fire-resistant partition board, a good fire isolation effect is achieved.

[0106] Furthermore, the lower surface of the partition top plate 39 forms the ceiling of the vehicle-carrying area and adopts a complete planar structure. This planar structure effectively prevents the accumulation of flammable gases at the bottom of the main deck when loading new energy vehicles, thereby avoiding the potential risk of subsequent explosions.

[0107] Furthermore, the height of the partition top plate 39 is at least 900mm; through the above height dimension design, the best protective isolation effect is ensured, and such a structure can meet the structural strength requirements of large spans without supporting columns in the middle.

[0108] Furthermore, the spacing between the strong crossbeams 37 does not exceed 3m. Through the structural design of the aforementioned strong crossbeams 37, the strength and reliability of the internal support structure of the isolated air chamber layer 35 are ensured.

[0109] Furthermore, the corner where the large-span box-type sheet structure connects to the transition sidewall of the hull is transitioned by a box-shaped arc structure 38; thus, stress concentration can be effectively eliminated.

[0110] Furthermore, the side transition wall 41 and the large-span box-type sheet structure are connected by an arc transition to form a large-span portal structure. This, in turn, achieves a good ventilation effect.

[0111] Furthermore, the vehicle loading area includes a fuel-powered vehicle loading area 42, a natural gas vehicle loading area 43, an electric vehicle loading area 44, and a hydrogen fuel cell vehicle loading area 45. This division of loading areas allows for the loading of different types of new energy vehicles, enhancing adaptability.

[0112] Furthermore, existing standards and regulations for roll-on / roll-off (Ro-Ro) ships stipulate that when loading vehicles, there should be a 300mm longitudinal clearance between vehicles, a 700mm lateral passage between every four vehicles, and a 500mm longitudinal passage between vehicles in the left and right directions. There should also be an 850mm longitudinal passage between vehicles and the sides of the ship.

[0113] When loading new energy vehicles, frequent inspections are required. In case of fire hazards, in addition to automatic fire control, manual firefighting with portable equipment is necessary for immediate suppression. The current vehicle arrangement and passageway layout, with a width of only 300mm laterally, makes it difficult for firefighters to enter between any individual vehicles, failing to meet this essential requirement. Therefore, the vehicle arrangement and passageway layout in the new energy vehicle loading area require new standards for the longitudinal and transverse widths of the passageways in the development of passenger roll-on / roll-off ships. This is to facilitate inspections and extinguish fires in their early stages, thereby ensuring the safety of the new energy Type II passenger roll-on / roll-off ships carrying new energy vehicles and the lives and property of passengers and property.

[0114] Based on this, the specific design for vehicle layout and access routes in the vehicle-carrying area adopts the following: vehicle width is designed to be 2.7m, with transverse passages at the front and rear ends at least 1.5m wide; longitudinal passages between vehicles in the left and right directions are at least 700mm wide; transverse passages in the front and rear directions are at least 1000mm wide; and the distance between the inner walls of both sides of the main deck above vehicle deck 1 and the vehicles is at least 1000mm. In this way, independent and interconnected longitudinal and transverse passages are formed between all vehicles, providing immediate access to each individual vehicle for inspection. This provides a solution for workers and firefighters to accurately eliminate potential hazards.

[0115] Furthermore, in order to respond quickly in the event of a fire and prevent the fire from spreading, the following plan is implemented: In a preferred embodiment, multiple sets of flexible fireproof curtains 50 are retracted and installed on the lower surface of the partition top plate 39 along the width direction of the hull 7. The fireproof curtains 50 are used to open in the event of a fire to divide the vehicle area into multiple relatively enclosed fireproof zones. The fireproof curtains 50 effectively separate and prevent the spread of fire, serving a good emergency response purpose. Furthermore, the fireproof curtains 50 are flexible structures; in normal conditions, they can be retracted to the side of the hull, without occupying hull space or affecting loading operations.

[0116] In a preferred embodiment, multiple fireproof cover delivery tracks 52 are installed on the lower surface of the partition top plate 39 along the length of the hull 7. The fireproof cover delivery tracks 52 are used to slide fireproof covers 51. When a vehicle catches fire, the fireproof cover 51 is quickly slid along the delivery tracks 52 to directly above the vehicle and lower itself to cover the burning vehicle. When not in use, the fireproof cover 51 is stored on the hull 7. Limiting blocks 53 are provided at the ends of the fireproof cover delivery tracks 52 for limiting movement. By setting up the fireproof cover 51, it is ensured that in the event of a fire, the fireproof cover 51 can be quickly moved to directly above the vehicle, thereby covering the vehicle and preventing the spread of fire, achieving a good fire prevention effect. Furthermore, the fireproof cover delivery tracks 52 located at the top facilitate the rapid delivery of the fireproof cover 51, avoiding obstacles during subsequent movement and improving the timeliness of the response.

[0117] Example 2: See Figure 1-31 This embodiment provides a 130m passenger roll-on / roll-off ship for loading new energy vehicles. Based on the traditional passenger roll-on / roll-off ship, this new energy passenger roll-on / roll-off ship was designed in accordance with the requirements of the "Announcement", "Guidelines" and "Guiding Opinions" after a preliminary risk assessment.

[0118] 1. According to the guidelines, "A risk assessment must be conducted and approved by CCS for hydrogen-powered or natural gas-powered vehicles. The risk assessment should include, but is not limited to, the following: The ventilation conditions of the premises can ensure that any leaked gas can be removed in a timely manner under any circumstances, so as not to cause the risk of fire or explosion; 2. The ship's safety design ensures that in high-risk scenarios, fires and explosions resulting from vehicle fuel leaks / spreads will not compromise the safe evacuation of passengers. To achieve the above technical objectives, the following solution is provided in this embodiment: Vehicle layout and passageway design in the loading area: The vehicle width is determined to be 2.7m. To facilitate personnel passage, operation, and inspection, the transverse passage at the front and rear ends is determined to be 1.5m. The longitudinal passage width between vehicles in the left and right directions is 700mm (when the width of the loaded vehicle is >2.7m, the principle is to ensure that the longitudinal passage between vehicles is greater than 700mm). The transverse passage width in the front and rear directions is 1000mm. The distance between the inner walls of both sides above the loading deck and the vehicles is 1000mm.

[0119] In this way, all vehicles are connected by independent longitudinal and lateral passageways, providing immediate access to each individual vehicle for inspection. This offers a solution for workers and firefighters to accurately eliminate potential hazards.

[0120] 2. Deck structure above the vehicle carrying area: 2.1. Upper deck and portal frame structure: To enhance the safety of the upper deck passenger cabins and common areas, an A60-class fire-resistant partition roof is installed below the upper deck and between the upper deck and the vehicle area to create an isolated cabin layer. This roof uses A60-class fire-resistant partitions, thus improving the fire separation between the deckhouse and common areas on the conventional upper deck and enhancing safety.

[0121] This isolation layer is designed to be 900mm high. At this height, strong transverse beams are installed at 3m intervals, and strong longitudinal girder is designed with appropriate spacing. Combined with ordinary deck longitudinals, this forms a large-span box-type sheet structure with a height of 900mm. This structure meets the structural strength requirements for a large span without supporting columns in the middle.

[0122] 2.2. The corners where the large-span box-type hull connects to the transition wall on the side of the hull are connected by a box-shaped arc transition to eliminate stress at the corners.

[0123] 2.3 The side transition wall and the large-span box-type panel are connected by a circular arc transition to form a large-span portal structure.

[0124] 2.4 The top deck below the upper deck is separated from the vehicle area by an A60-class partition. This ensures a safe separation between the cabins and densely packed personnel areas on the upper deck and the vehicle area.

[0125] Finally, the main parameters of the designed 130m passenger ro-ro ship for carrying new energy vehicles are shown in Table 1: Table 1. Main parameters of a 130m passenger ro-ro ship carrying new energy vehicles

[0126] Example 3: Fire control on conventional passenger roll-on / roll-off ships primarily relies on traditional fire extinguishing methods such as water-based fire suppression, foam fire suppression, and carbon dioxide fire suppression. However, for new energy vehicles, especially electric vehicles equipped with lithium batteries, the main cause of spontaneous combustion and explosion is battery thermal runaway, which is difficult to extinguish using conventional fire suppression methods.

[0127] Recently, the industry has developed a method for extinguishing fires in new energy vehicles by using protective blankets for physical isolation, which is superior to traditional fire extinguishing methods.

[0128] However, in reality, the loading area of ​​passenger roll-on / roll-off ships is densely packed with vehicles, making it difficult to implement the method of manually covering fire blankets due to the narrow passageways.

[0129] For cargo vehicles carrying new energy vehicles, which are tall and require fire blankets to cover the entire vehicle for fire extinguishing, the large size and weight of the fire blankets make manual covering difficult. Therefore, based on the passenger roll-on / roll-off ship example in Example 1, the following solution is further improved.

[0130] See Figure 32-50 In a preferred embodiment, an open-air area 58 without a superstructure is provided above the bow and stern of the main deck 1. The open-air area 58 is equipped with elevated walkways on all sides, serving as elevated passageways for personnel passage, escape, and fire fighting.

[0131] In a preferred embodiment, the elevated walkway is equipped with a portable crane for transporting fire blankets 55, which can be quickly activated to extinguish and isolate fires in new energy vehicles that have caught fire using physical methods with fire blankets 55; wherein, the first portable crane is a longitudinally and laterally traveling crane 56, and the traveling crane 56 is supported on the top of the crane track 57; the rear portable crane is a longitudinally fixed and laterally traveling fixed crane 54.

[0132] The following technical approach is used to lift and deliver fire blankets: Design a dedicated lightweight gantry crane. The crane adopts an electric remote control operation. The traveling trolley travels in four directions: front, back, left, and right, fully covering the area where new energy vehicles are loaded.

[0133] Another type of lightweight crane is longitudinally fixed and laterally travels to fully cover the area where new energy vehicles are loaded. The rails are arranged on a fixed gantry structure.

[0134] Furthermore, based on the dimensions of the new energy vehicles being loaded, fireproof stretch blankets were procured from a specialized factory. These fireproof blankets are five-sided, with a high-strength steel frame on top, approximately 5% larger than the dimensions of the new energy vehicles, connected to the five-sided fireproof blanket. Small magnets are densely distributed along the bottom edge of the five-sided blanket for connection. The crane uses a double hook, with a connecting arm beneath each hook. The connecting arm uses an automatic gravity release device to hook onto the eyelet of the steel frame on top of the fireproof blanket. In this way, the crane hooks are connected via the connecting arm, the automatic gravity release device, and the eyelet of the steel frame on top of the fireproof blanket.

[0135] The effective lifting and lowering height of the crane is twice the height of the new energy vehicle being carried, plus 200mm.

[0136] Before the new energy vehicles are rolled onto the ship, a crane is activated to lift the five-sided fireproof blanket with a steel frame to its highest point, creating sufficient height space for the vehicles. The new energy vehicles can then be smoothly rolled onto the designated location.

[0137] After the new energy vehicles are fully loaded, the fire blanket with a steel frame top, which was placed too high, is moved to be placed on top of any of the new energy vehicles. Utilizing the large opening at the bottom of the five-sided fire blanket with its shaped steel frame, the blanket can be easily placed on top of any new energy vehicle for storage. This storage method should ensure that the automatic gravity unhooking device is in a state of being under load but not disengaged, ready for immediate lifting.

[0138] In this way, when any new energy vehicle in the area where new energy vehicles are installed detects an alarm, a portable crane will be immediately activated to load a fire blanket onto the vehicle and lower it to fully cover the fire-stricken new energy vehicle.

[0139] The magnets at the bottom edge of the fire blanket, close to the vehicle deck, quickly and completely seal the new energy vehicle on all six sides under magnetic force, achieving complete physical isolation and controlling the fire risk to an acceptable level.

[0140] Simultaneously, the crane hook is lowered to a slack state, and the gravity automatic unhooking device disengages. The crane then completes the deployment of the fire blanket.

[0141] The number of these fire blankets can be one or more. After the crane delivers one blanket, it can continue the same process to deliver the second and third.
