Description

Technical Field

[0001] This invention relates to a multi-functional hydrogen-powered emergency rescue and disaster relief power generation vessel. Background Technology

[0002] Water rescue vessels used in emergency rescue and disaster relief are important equipment for protecting people's lives and property and responding to sudden natural disasters.

[0003] Currently, the main type of vessel used for emergency rescue in China is the traditional diesel-powered rescue vessel, which uses a diesel engine as its power source and propels a propeller through an internal combustion engine. These vessels have revealed the following technical shortcomings in long-term use:

[0004] First, the reliance on fossil fuels poses environmental pollution problems. Diesel-powered rescue vessels generate large amounts of harmful emissions such as carbon dioxide and nitrogen oxides during operation, which threaten the health of rescuers and trapped individuals in the enclosed or semi-enclosed environments of disaster areas, while also increasing secondary pollution of the disaster area. With increasingly stringent environmental protection requirements, the use of such vessels is being restricted.

[0005] Secondly, the operating noise is relatively high. Diesel engines are noisy, which can easily generate significant noise during water search and rescue operations. This is detrimental to precise operations in environments where quiet is required, such as during post-disaster search and rescue of trapped personnel. The noise can interfere with acoustic detection and voice communication, as well as disrupt rescue command communications.

[0006] Third, power supply capacity is limited. The existing rescue ships are mainly focused on personnel transportation and limited material transfer, lacking the ability to provide large-scale emergency power to the shore. Even if a few ships are equipped with generator sets, their power supply capacity is insufficient to meet the power needs of multiple points of operation in the disaster area, such as communication base stations, temporary medical points, and lighting systems.

[0007] Fourth, the disaster relief functions are limited and the integration is low. Most existing rescue ships are designed for a single function and lack the comprehensive response capability to meet the multi-scenario needs of disaster relief. They cannot simultaneously meet the needs of multiple tasks such as personnel search and rescue, emergency power supply, communication relay, and command of disaster relief operations on a single ship.

[0008] Therefore, a new technical solution is needed to address the technical problems of existing water rescue vessels, such as environmental pollution, noise interference, insufficient power supply, and low functional integration. Summary of the Invention

[0009] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hydrogen-powered emergency rescue and disaster relief power generation multi-functional vessel to solve the following technical problems existing in the prior art:

[0010] The power system relies on fossil fuels and generates a large amount of harmful emissions such as carbon dioxide and nitrogen oxides during operation. In the closed or semi-closed environment of the disaster area, it poses a threat to people's health and causes secondary environmental pollution.

[0011] Diesel engines are noisy, which is not conducive to delicate operations that require a quiet environment, such as disaster relief and rescue of trapped people.

[0012] The existing rescue ships have limited power supply capacity, which is insufficient to meet the power needs of high-power loads at multiple locations such as communication base stations, temporary medical points, and lighting systems in the disaster area.

[0013] The disaster relief function is limited and the integration is low, making it impossible to simultaneously meet the needs of multiple tasks such as personnel search and rescue, emergency power supply, communication relay, and command of rescue operations on a single vessel.

[0014] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] A hydrogen-powered emergency rescue and disaster relief power generation multi-functional vessel includes a vessel body, a hydrogen containment system, a power generation, distribution and transmission system, a box-type battery delivery system, a lifting operation system, living quarters and a search and rescue system, wherein the vessel body includes a vessel structure and a propulsion system;

[0016] The hydrogen containment system includes a tubular hydrogen storage tank and a hydrogen supply pipeline, wherein the tubular hydrogen storage tank is installed within the ship structure.

[0017] The power generation, distribution and transmission system includes a hydrogen fuel cell stack, an energy bridge, a distribution cabinet and a box-type power supply. The hydrogen fuel cell stack is connected to the hydrogen supply pipeline. The hydrogen fuel cell stack and the box-type power supply are respectively electrically connected to the energy bridge. The energy bridge is electrically connected to the distribution cabinet. The distribution cabinet is electrically connected to the propulsion system.

[0018] The box-type battery delivery system includes a gantry-type lifting device, a delivery track, and an electric delivery trolley. The gantry-type lifting device is installed on the stern main deck of the ship. The delivery track is laid on the main deck and extends longitudinally along the ship. The electric delivery trolley is installed on the delivery track. The gantry-type lifting device includes a clamp, which is detachably connected to the box-type power supply. The electric delivery trolley is used to carry the box-type power supply and move along the delivery track.

[0019] The lifting operation system includes a full-slewing crane, which is installed on the main deck in the bow area of ​​the ship's hull; the living quarters are located in the deckroom of the ship's structure; the search and rescue system includes an underwater topographic detection device.

[0020] Furthermore, the ship structure includes a main hull, which is divided into several functional compartments by bulkheads. The functional compartments include a left hydrogen cylinder storage compartment, a right hydrogen cylinder storage compartment, and an empty compartment located between the two. The tubular hydrogen storage tanks are respectively installed in the left hydrogen cylinder storage compartment and the right hydrogen cylinder storage compartment. The empty compartment is used to isolate the left hydrogen cylinder storage compartment and the right hydrogen cylinder storage compartment.

[0021] Furthermore, the ship structure also includes a deckhouse, which is divided into a lower deckhouse and an upper deckhouse by the living quarters. The lower deckhouse is further divided into a left section and a right section. The left section includes a left fuel cell compartment and a left power distribution compartment, and the right section includes a right fuel cell compartment and a right power distribution compartment. The hydrogen fuel cell stacks are respectively located in the left fuel cell compartment and the right fuel cell compartment, and the energy bridge and the power distribution cabinet are respectively located in the left power distribution compartment and the right power distribution compartment.

[0022] Furthermore, the gantry hoisting device includes a base, a gantry, a winch, clamps, and a hydraulic system. The base is fixedly connected to the main deck, the gantry is mounted on the base, the winch is installed on the top of the gantry, the clamps are raised and lowered by the winch, and the hydraulic system drives the gantry to swing.

[0023] Furthermore, the power generation, distribution and transmission system also includes a combiner cabinet and a cable winch. The combiner cabinet is electrically connected to the distribution cabinet and is used to manage the charging and discharging circuits of the box-type power supply. The cable winch is installed on the main deck and is used to supply power to the outside.

[0024] Furthermore, the power generation, distribution, and transmission system has navigation and propulsion modes, external power supply modes, emergency rescue and disaster relief modes, and shore power charging modes. In the navigation and propulsion mode, the electrical energy generated by the hydrogen fuel cell stack is supplied to the propulsion system through the distribution cabinet. In the external power supply mode, the electrical energy of the box-type power supply is supplied to the outside through the distribution cabinet.

[0025] Furthermore, the hydrogen containment system also includes a hydrogen refueling pipeline and a hydrogen refueling station. The hydrogen refueling station is located on the main deck and above the tubular hydrogen storage tank. The hydrogen refueling pipeline connects the hydrogen refueling station and the tubular hydrogen storage tank.

[0026] Furthermore, the lifting operation system also includes a crane operator's cab and a ladder. The crane operator's cab integrates a driving system that enables manned operation on board and remote control operation from shore. The ladder connects the main deck to the crane operator's cab.

[0027] Furthermore, the living quarters include a crew living area and a temporary resettlement area for disaster victims, which are divided into sections within the deck interior.

[0028] Furthermore, the propulsion system includes a propulsion motor, a gearbox, a shaft system, and a propeller. The propulsion motor is housed in a propulsion motor compartment within the ship's structure. The propulsion motor is connected to the shaft system via the gearbox, and the propeller is located at the end of the shaft system. The underwater terrain detection device is housed in a spare parts and tool compartment within the ship's structure. The search and rescue system also includes a searchlight system and a loudspeaker system, which are located on the roof deck of the ship's structure.

[0029] Compared with the prior art, the beneficial effects of the present invention are: the present invention uses hydrogen fuel cell stack as the main power source, and only emits water during operation, avoiding harmful emissions such as carbon dioxide, nitrogen oxides, and particulate matter. It has low operating noise, reduces acoustic interference in rescue operations, improves the environmental quality of water areas in disaster areas, and is conducive to refined operations in search and rescue scenarios that require a quiet environment.

[0030] Hydrogen fuel cell stacks directly convert chemical energy into electrical energy without the need for combustion, and their energy conversion efficiency is far higher than that of internal combustion engines. Furthermore, this invention utilizes the dual functions of hydrogen fuel cell stacks for both driving and power generation. In the case of external power supply, more than 300 kilowatts of AC power can be transmitted to the shore via cable winch, which can meet the power needs of multiple scenarios such as communication, medical care, lighting, and rescue equipment in disaster areas, and fill the technological gap of the limited power supply capacity of existing water rescue vessels.

[0031] Through modular integrated design, this invention integrates multiple functions such as personnel search and rescue, emergency power supply, material loading and unloading, and personnel resettlement on a single vessel, which can quickly respond to the rescue needs of different types of disasters and greatly improve the efficiency of disaster relief.

[0032] Hydrogen fuel cell systems have high energy density and a range of no less than 200 kilometers under rated operating conditions, which can meet the long-distance sailing needs from the nearest port to distant disaster areas and overcome the shortcomings of insufficient range of pure lithium battery ships.

[0033] The hydrogen fuel cell stack adopts a modular distributed design, with one set on each of the port and starboard sides, and each set is independently backed up. The box-type power supply can be flexibly loaded and unloaded through the box-type battery delivery system to achieve rapid energy replenishment. The hydrogen containment system adopts two independently arranged sets, which improves system reliability and effectively ensures the safe operation of the ship in complex disaster environments.

Detailed Implementation

[0041] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0042] Example 1

[0043] Please refer to Figure 1-6 A hydrogen-powered emergency rescue and disaster relief multi-functional vessel includes a ship body 1, a hydrogen containment system 3, a power generation, distribution and transmission system 4, a box-type battery delivery system 2, a lifting operation system 5, living quarters 6, and a search and rescue system 7. The ship body 1 includes a ship structure 11 and a propulsion system 12. The ship structure 11 is made of steel or aluminum and is divided into a main hull 111, a deckhouse 112, a main deck 113, a living deck 114, and a roof deck 115. The main hull 111 is the area of ​​the ship structure 11 below the main deck 113, which is divided into several functional compartments by bulkheads, including the port stern ballast water tank 1111P, the starboard stern ballast water tank 1111S, the steering gear room 1112, the propulsion motor room 1113, the port hydrogen cylinder storage tank 1114P, the starboard hydrogen cylinder storage tank 1114S, the empty compartment 1114C, the port ballast water tank 1115P, the starboard ballast water tank 1115S, the spare parts and tools compartment 1115C, the port bow tip ballast water tank 1116P, and the starboard bow tip ballast water tank 1116S. The port hydrogen cylinder storage compartment 1114P and the starboard hydrogen cylinder storage compartment 1114S are located on opposite sides of the midship section of the hull and are used to store the bundled hydrogen storage tanks 31. An empty compartment 1114C is located between the port and starboard hydrogen cylinder storage compartments 1114P and 1114S, serving as a safety isolation compartment. The isolation provided by the empty compartment 1114C effectively reduces the safety risk in the event of hydrogen leakage. The port stern ballast water tanks 1111P and 1111S are located on opposite sides of the stern section of the hull and are used to adjust the trim and list at the stern. The port ballast water tanks 1115P and 1115S are located on opposite sides of the mid-forward section of the hull and are used to adjust the list. The port bow ballast water tanks 1116P and 1116S are located on opposite sides of the foremost section of the hull and are used to adjust the trim and list at the bow. By adjusting the aforementioned ballast water tanks, the ship's stability can be maintained during the loading and unloading of the box-type power supply 8 and under different operating conditions. The steering gear compartment 1112 is located in the center of the stern and houses the steering mechanism 141; the propulsion motor compartment 1113 is located in front of the steering gear compartment 1112 and houses the propulsion motor 121; the spare parts and tools compartment 1115C is located between the port ballast water tank 1115P and the starboard ballast water tank 1115S and is used to store spare parts, tools, and the underwater topography detection device 71.

[0044] Deckhouse 112 is the area of ​​the ship's structure 11 above the main deck 113, divided into lower deckhouse 1121 and upper deckhouse 1122 by the living deck 114. Lower deckhouse 1121 is further divided into the port section 1121P and the starboard section 1121S. The port section 1121P includes the port engine room stairwell 11211P, the port fuel cell room 11212P, and the port electrical equipment room 11213P. The starboard section 1121S includes the starboard engine room stairwell 11211S, the starboard fuel cell room 11212S, and the starboard electrical equipment room 11213S. This symmetrical arrangement on both sides allows for redundancy of the power and electrical systems, improving system reliability. Upper deckhouse 1122 is used entirely as living quarters 6. The propulsion system 12 includes a propulsion motor 121, a gearbox 122, a shaft system 123, and a propeller 124. The propulsion motor 121 is installed in the propulsion motor nacelle 1113 and is connected to the shaft system 123 through the gearbox 122. The propeller 124 is located at the end of the shaft system 123, underwater at the stern of the hull, and is driven by the propulsion motor 121 to generate thrust. The ship body 1 also includes anchoring and mooring equipment 13 and steering equipment 14. The anchoring and mooring equipment 13 includes bollards 131, electric winches 132, cable guides 133, cable guide rollers 134, cable guides 135, short anchor chains 136, anchors 137, anchor frames 138, and wire cables 139, distributed at the bow, stern, and both sides of the main deck 113, for anchoring, berthing, and mooring operations of the ship. The steering equipment 14 includes a steering mechanism 141 and a rudder blade 142. The steering mechanism 141 is installed in the steering gear compartment 1112 and drives the rudder blade 142 to rotate through a transmission mechanism to achieve the heading control of the ship.

[0045] The hydrogen containment system 3 includes a bundled hydrogen storage tank 31, a hydrogen refueling pipeline 32, a hydrogen supply pipeline 33, and a hydrogen refueling station 34. Two sets of the hydrogen containment system 3 are installed on the ship, one on each side. The two bundled hydrogen storage tanks 31 are respectively located in the port hydrogen cylinder storage tank 1114P and the starboard hydrogen cylinder storage tank 1114S. The two hydrogen refueling stations 34 are respectively located on the port and starboard sides of the main deck 113, directly above the port hydrogen cylinder storage tanks 1114P and 1114S. The hydrogen refueling pipeline 32 connects the hydrogen refueling station 34 to the bundled hydrogen storage tanks 31. This arrangement minimizes the length of the hydrogen refueling pipeline 32, reduces safety risks, and facilitates rapid hydrogen refueling. Hydrogen fuel is stored in a tubular hydrogen storage tank 31 via hydrogen refueling station 34 and hydrogen refueling pipeline 32, and then transported to the hydrogen fuel cell stack 41 via hydrogen supply pipeline 33. The hydrogen containment system 3 is equipped with comprehensive safety protection measures, including hydrogen leak detection sensors, an alarm linkage system, and an emergency shut-off valve. Hydrogen leak detection sensors are distributed around the left hydrogen cylinder storage compartment 1114P, the right hydrogen cylinder storage compartment 1114S, the hydrogen refueling station 34, and at key locations along the hydrogen supply pipeline 33, for real-time monitoring of hydrogen concentration. When a hydrogen leak is detected, the alarm linkage system immediately activates an audible and visual alarm and notifies the driving system 91. Simultaneously, the emergency shut-off valve automatically closes the hydrogen supply pipeline 33, cutting off the hydrogen supply and preventing the leak from escalating. Furthermore, both the left hydrogen cylinder storage compartment 1114P and the right hydrogen cylinder storage compartment 1114S are equipped with forced ventilation systems to ensure air circulation within the compartments and reduce the risk of hydrogen accumulation.

[0046] The power generation, distribution, and transmission system 4 includes hydrogen fuel cell stacks 41, energy bridges 42, distribution cabinets 43, box-type power supplies 8, combiner cabinets 47, and cable winches 48. One set of the power generation, distribution, and transmission system 4 is installed on each of the port and starboard sides. Two sets of hydrogen fuel cell stacks 41 are located in the port fuel cell compartment 11212P and the starboard fuel cell compartment 11212S, respectively. Two sets of energy bridges 42, two sets of distribution cabinets 43, and two sets of combiner cabinets 47 are located in the port power distribution compartment 11213P and the starboard power distribution compartment 11213S, respectively. Two cable winches 48 are located on the main deck 113 near the power distribution compartments. The hydrogen fuel cell stacks 41 are connected to the hydrogen supply pipeline 33, converting hydrogen energy into electrical energy. The hydrogen fuel cell stacks 41 and the box-type power supply 8 are electrically connected to the energy bridges 42, the energy bridges 42 are electrically connected to the distribution cabinets 43, and the distribution cabinets 43 are electrically connected to the propulsion system 12. The electricity generated by the hydrogen fuel cell stack 41 and the electrical energy from the box-type power supply 8 are transmitted through transmission lines to the energy bridge 42 for peak shaving and valley filling to generate a stable current, which is then fed into the distribution cabinet 43 to provide unified distribution for the power required by the entire ship and the power output to external devices. The combiner cabinet 47 is electrically connected to the distribution cabinet 43 and is used to manage the charging and discharging circuits of the box-type power supply 8, and to realize functions such as power distribution, external wiring harness connection, human-machine interface display, alarm prompts, buzzer prompts, and emergency stop control. The cable winch 48 is used to supply power to the outside, which can transmit electrical energy to shore or external electrical equipment. The power generation, distribution and transmission system 4 has four operating modes: navigation and propulsion mode, external power supply mode, disaster relief mode, and shore power charging mode. In the navigation and propulsion mode, the electrical energy generated by the hydrogen fuel cell stack 41 is prioritized to meet the needs of the propulsion system 12 and daily loads through the distribution cabinet 43, and the excess electrical energy is stored in the box-type power supply 8 for peak shaving. In external power supply mode, when the ship is anchored or moored, the power from the containerized power supply 8 is supplied to the outside through the distribution cabinet 43. When the power level of the containerized power supply 8 falls below 20% of its total capacity, the hydrogen fuel cell stack 41 starts to charge the containerized power supply 8. In disaster relief mode, the power generated by the hydrogen fuel cell stack 41 and the power from the containerized power supply 8 are combined to supply power to the lifting operation system 5 through the distribution cabinet 43. In shore power charging mode, shore power charges the containerized power supply 8 through the combiner cabinet 47. This multi-mode design enables flexible energy allocation and improves the system's adaptability.

[0047] The box-type battery delivery system 2 includes a gantry-type lifting device 21, a delivery track 22, and an electric delivery trolley 23. The gantry-type lifting device 21 is installed on the stern main deck 113 of the ship's hull 1. The delivery track 22 is laid on the main deck 113 and extends longitudinally along the ship. The electric delivery trolley 23 is installed on the delivery track 22. The gantry-type lifting device 21 includes a base 211, a gantry 212, a winch 213, a clamp 214, and a hydraulic system 215. The base 211 is fixed to the main deck 113. The gantry 212 is installed on the base 211. The winch 213 is installed on top of the gantry 212. The clamp 214 is raised and lowered by the winch 213, and the hydraulic system 215 drives the gantry 212 to swing. This gantry structure design allows the box-type power supply 8 to be lifted from outside the ship onto the ship or from the ship onto the outside along an arc-shaped trajectory, enabling rapid loading and unloading operations. The gantry crane 21 is welded to the ship's hull 1 via a base 211 and fixed to the stern main deck 113. A winch 213 is mounted on top of the gantry 212 and is used to raise and lower the clamp 214. The gantry 212 is driven by a hydraulic system 215 to swing its arm towards the stern or into the ship. The clamp 214 is detachably connected to the box-type power supply 8 and is used to grab and release the box-type power supply 8. A conveyor track 22 is laid on the mid-to-aft main deck 113 of the ship's hull 1, arranged longitudinally along the ship, and is used to carry and guide the electric conveyor trolley 23, and can supply power to the electric conveyor trolley 23. The electric conveyor trolley 23 carries the box-type power supply 8 and moves along the conveyor track 22. It is connected and fixed to the box-type power supply 8 via a standard container stacking cone and has a braking and locking function to prevent the box-type power supply 8 from shifting during navigation. During the loading operation of the box-type power supply 8, the gantry 212 swings its arm towards the stern via the hydraulic system 215, the clamp 214 grabs the box-type power supply 8, and then swings its arm forward to above the stern deck before slowly lowering it to place the box-type power supply 8 onto the electric conveyor trolley 23. The electric conveyor trolley 23 then transports the box-type power supply 8 towards the bow to the designated position via the conveyor rail 22 before braking and locking. During the unloading operation of the box-type power supply 8, the electric conveyor trolley 23 releases its brake and transports the box-type power supply 8 towards the stern via the conveyor rail 22 to the stern of the main deck 113. The clamp 214 grabs the box-type power supply 8 and lifts it up, while the gantry 212 swings its arm towards the stern to lift the box-type power supply 8 off the hull.

[0048] The lifting operation system 5 includes a full-slewing crane 51, a crane operator's cab 52, and a ladder 53. The full-slewing crane 51 is located on the main deck 113 at the bow of the vessel hull 1, enabling 360-degree full-slewing operation for loading and unloading disaster relief supplies and on-site emergency rescue operations. The crane operator's cab 52 integrates a driving system 91, which can operate in both manned onboard and shore-based remote control modes. This integrated design combines the ship's bridge and the crane operator's cab into one, reducing the complexity of the superstructure and providing the operator with optimal visibility of the lifting operations at the bow while controlling the vessel. The ladder 53 connects the main deck 113 to the crane operator's cab 52, providing access to the crane operator's cab 52 for operators or drivers. A material storage area 54 is located on the main deck 113 aft of the full-slewing crane 51 for storing rescue supplies and emergency equipment. The shore-based remote control navigation function of the navigation system 91 is realized through satellite communication or 4G / 5G communication links. Control commands are transmitted from the shore-based command center to the ship through the communication link. After receiving the commands, the navigation system 91 controls the propulsion system 12 and the steering equipment 14 to perform corresponding actions. When remote control communication is lost, the navigation system 91 automatically switches to safety mode, the ship decelerates and maintains the current course, and waits for communication to be restored or for manual takeover.

[0049] The living quarters 6 are located within the deckhouse 112 of the ship's structure 11, specifically within the upper deckhouse 1122. Living quarters 6 includes a crew living area 61 and a temporary disaster relief area 62, which are separated within the deckhouse 112. This zoning design clearly demarcates the activity areas for rescue personnel and those being rescued, facilitating management. Living quarters 6 also includes a men's toilet 63, a women's toilet 64, a men's bathroom 65, a women's bathroom 66, an office 67, a kitchen 68, and a dining hall 69. The crew living area 61 is for the daily living of rescue crew members; the temporary disaster relief area 62 is for accommodating rescued disaster victims; the men's toilet 63, women's toilet 64, men's bathroom 65, and women's bathroom 66 provide basic sanitation facilities; the office 67 is used for rescue command and administration; and the kitchen 68 and dining hall 69 provide catering services for crew members and disaster victims. Living quarters 6 are located in the upper deckhouse 1122, which is isolated from the machinery area of ​​the lower deckhouse 1121, ensuring living comfort and safety.

[0050] The search and rescue system 7 includes an underwater topography detection device 71, a searchlight system 72, and a loudspeaker system 73. The underwater topography detection device 71 is located in the spare parts and tool compartment 1115C within the ship's structure 11. It utilizes multibeam echo sounders, side-scan sonar, or underwater 3D scanning sonar to detect the underwater topography of the disaster area, providing underwater environmental information for rescue operations. The searchlight system 72 and the loudspeaker system 73 are located on the roof deck 115 of the ship's structure 11. The searchlight system 72 illuminates the search and rescue area at night or in low visibility conditions, while the loudspeaker system 73 is used to issue calls or commands to the surface and shore to assist in the search and rescue of affected people. The ship also has other systems 9, including a navigation system 91 and a satellite positioning system 92. The navigation system 91 is integrated into the crane operator's compartment 52, enabling both manned onboard navigation and shore-based remote control navigation modes, improving the ship's adaptability in complex disaster environments. The satellite positioning system 92 is used for real-time positioning of the ship, providing precise location information for rescue operations. Its antenna and related equipment are installed above the roof deck 115.

[0051] Implementation Principle: When using this multi-functional emergency rescue vessel for rescue missions, the vessel is first navigated to the disaster area waters via the navigation system 91. In propulsion mode, the electrical energy generated by the hydrogen fuel cell stack 41 is supplied to the propulsion system 12 through the energy bridge 42 and the distribution cabinet 43. The propulsion motor 121 drives the propeller 124 to rotate, generating thrust, and the steering mechanism 141 controls the rudder blades 142 to rotate, achieving course adjustment. Excess electrical energy is stored in the box-type power supply 8 for peak shaving. Upon arrival in the disaster area, the vessel switches to the appropriate operating mode according to rescue needs. If external power supply is required, the vessel enters the external power supply mode. The electrical energy from the box-type power supply 8 is managed through the distribution cabinet 43 and the combiner cabinet 47, and then transmitted to the shore via the cable winch 48, providing over 300 kilowatts of AC power to meet the power needs of communication, medical care, and lighting in the disaster area. When the power level of the box-type power supply 8 falls below 20% of its total capacity, the hydrogen fuel cell stack 41 automatically starts to recharge it. If material loading / unloading or on-site emergency rescue operations are required, the ship enters the disaster relief and rescue mode. The hydrogen fuel cell stack 41 and the box-type power supply 8 jointly power the lifting operation system 5, and the full-rotation crane 51 performs a 360-degree full-rotation operation to complete the material lifting. If the box-type power supply 8 needs to be replenished, it is quickly loaded and unloaded through the box-type battery conveying system 2: the gantry 212 of the gantry lifting device 21 swings its arm towards the stern, the clamp 214 grabs the box-type power supply 8 and then swings its arm forward to above the stern deck, slowly lowering it onto the electric conveyor trolley 23, which transports it to the designated location along the conveyor track 22. The underwater terrain detection device 71 of the search and rescue system 7 detects the underwater environment, and the searchlight system 72 and the loudspeaker system 73 assist in nighttime search and rescue. The living quarters 6 provide accommodation and living support for the crew and rescued disaster victims. Through the coordinated work of various systems, a multi-functional integrated emergency rescue capability with zero emissions, low noise, and large-capacity power supply is achieved.
