Technical Field

[0002] Compared with traditional fuel-powered container ships, using hydrogen fuel cells as a power source for container ships not only makes the cruising range longer, but also reduces carbon dioxide emissions, thereby achieving low carbon emissions and reducing pollution; For example, the patent name disclosed in the prior art with the announcement number "CN115384746A" is "A Near-Zero Emission Logistics System for Large Container Ships", which discloses that a fuel cell cabin is provided under the superstructure, and an engine room is provided under the upper deck near the stern of the near-zero emission container ship. The ammonia fuel storage tank is arranged below the upper deck and is in the cargo hold section between the superstructure and the engine room. Moreover, the ammonia fuel storage tank is far away from the superstructure, and the impact of the dangerous area and the diffusion of toxic gases on personnel is minimized. The fuel cell cabin is arranged under the superstructure, which effectively utilizes the space under the superstructure and solves the problem of crowded engine room space. A hydrogen fuel cell module is provided in the fuel cell cabin to replace the use demand of the ship's main power station and meet the demand for large-capacity power stations of ocean-going large container ships. The fuel cell energy storage system is composed of a mobile container-type high-pressure hydrogen storage module, which occupies the container on the deck and can realize rapid loading and unloading. The gas processing cabin is arranged above the ammonia fuel storage tank, and the prior art announcement number "CN1 The patent name disclosed in "17208187A" is "A Zero Carbon Emission Container Ship", which discloses that the container ship includes a partition area on the main deck of the hull, a hydrogen fuel storage module is placed on the rear side of the partition area near the stern, and container cargo is placed on the front side. The hydrogen fuel storage module and the container cargo are separated by the partition area, which can ensure to the greatest extent that when hydrogen fuel leaks, fires and other accidents occur, the cargo in front will not be affected. The hydrogen fuel storage module is designed as a container-type design and is directly installed in the open-air area behind the partition area. When docking, the container can be directly changed, eliminating the step of refueling. At the same time, a matching hydrogen fuel preparation room and a hydrogen fuel connection place are arranged in the partition area to transport hydrogen fuel to the hydrogen fuel cell module. The ship is also provided with an electric energy storage module, which is also a container-type design to facilitate direct box change operations and is arranged at the rear side of the partition area as a supplementary power source. In addition, a number of water mist nozzles are arranged in the partition area for fire fighting to ensure safety.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0021] See also Figure 1-Figure 13 , the present invention provides the following technical solutions: Embodiment 1: The low-carbon emission hydrogen fuel cell powered container ship in this embodiment can remove impurities in the hydrogen fuel, thereby improving the reaction efficiency and service life of the hydrogen fuel cell, and also achieve the effect of low carbon emission. At the same time, it can also effectively reduce the pressure drop of the hydrogen fuel when passing through the filter assembly 18, thereby ensuring the efficient operation of the hydrogen fuel cell body 10.

[0022] The flow direction control mechanism includes a temporary storage frame 15 rotatably mounted on the left side of the filter 7. The interior of the temporary storage frame 15 is hollow. The pipeline on the right side of the conveying control mechanism 6 is inserted into the temporary storage frame 15 through rotation. A circle of diverter pipes 21 are evenly spaced on the right side of the temporary storage frame 15. The diverter pipes 21 are arranged in a "Z" shape. The right end of the diverter pipe 21 is inserted into the left side of the filter 7. A control gear 151 is installed on the outside of the temporary storage frame 15. The rear side of the control gear 151 is meshed and connected with a transmission gear 16 installed in the hull 1. The right end of the transmission gear 16 is connected to the motor installed in the hull 1. A support rod 181 is slidably connected to the inside of the right side of the filter 7 through a bracket. A connecting spring 182 is nested and connected to the outside of the right end of the support rod 181. Three groups of filter components 18 with different internal apertures are installed in sequence on the outside of the left end of the support rod 181. The outer side of the filter component 18 is arranged to fit the inner wall of the filter 7. A circle of fixed disks 20 are evenly spaced on the inner wall of the left side of the filter 7. The outer side of the shunt pipe 20 is arranged in an arc shape, a control plate 22 is fixedly connected to the outer side of the right end of the shunt pipe 21, a convex rod 221 is fixedly connected to the lower left side of the control plate 22, and a limit rod 222 is installed in the right side of the temporary storage frame 15 through an equidistant slot, and a convex rod 221 is arranged to penetrate the outer side of the limit rod 222, and a reset spring 223 is nested and connected to the outer side of the limit rod 222. The middle part of the shunt pipe 21 is made of a hose material, and the control plate 22 forms a reciprocating sliding structure through the fixed plate 20. The right side of the temporary storage frame 15 A first fixed tube 19 is fixed in the middle of the surface, and a first piston column 191 is connected to the inside of the right end of the first fixed tube 19. A support rod 181 is provided at the right end of the first piston column 191. The support rod 181 forms a left-right reciprocating sliding structure through the first piston column 191. A second fixed tube 23 is fixed through the outside of the left end of the first fixed tube 19 at equal intervals, and a second piston column 231 is fittedly connected to the inside of one end of the second fixed tube 23, and the other end of the second piston column 231 is connected to the convex rod 221.

[0023] During the travel of the hydrogen fuel cell powered container ship, the hydrogen fuel in the hydrogen storage tank 5 is transported to the filter 7 through the transport control mechanism 6. At this time, the hydrogen fuel first enters the temporary storage frame 15 rotatably connected to the left side of the filter 7, and then enters the filter 7 through multiple shunt pipes 21. At the same time, the motor on the rear side of the filter 7 is started, and the motor drives the transmission gear 16 to rotate. When the transmission gear 16 rotates, it drives the temporary storage frame 15 to rotate through the meshing control gear 151. When the temporary storage frame 15 rotates, it drives multiple "Z"-shaped shunt pipes 21 to revolve around the first fixed pipe 19 as the center of the circle. At the same time, when the control disk 22 outside the shunt pipe 21 rotates to contact and fit with the fixed disk 20, the fixed fixed disk 20 will apply an inward thrust to the control disk 22, so that The control disk 22 stretches the hose structure in the middle area of ​​the shunt tube 21, so that the control disk 22 can well drive the right end of the shunt tube 21 to move inward. At this time, the protruding rod 221 on the left side of the control disk 22 moves downward on the outside of the limit rod 222, and the reset spring 223 is squeezed and stored. When the control disk 22 rotates to separate from the fixed disk 20, as shown above, the control disk 22 is automatically reset by the stored force of the reset spring 223. This operation is repeated, so that the shunt tube 21 revolves around the center of the first fixed tube 19 while the right end of the shunt tube 21 reciprocates. Therefore, the shunt tube 21 can evenly transport the hydrogen fuel to the filter assembly 18 for filtering, thereby avoiding excessive local resistance of the filter assembly 18 and avoiding affecting the gas supply pressure of the hydrogen fuel cell.

[0024] Then the hydrogen fuel can be filtered through the filter assembly 18 to remove impurities in the hydrogen fuel, so as to prevent the impurities from damaging the catalyst and membrane electrode in the hydrogen fuel cell body 10 in the later stage, thereby achieving the effect of low carbon emission. At the same time, the convex rod 221 will drive the second piston column 231 to move inward together. At this time, the second piston column 231 squeezes part of the gas in the second fixed tube 23 and transports it to the first fixed tube 19, thereby causing the gas to automatically push the first piston column 191 to move to the right. Such repeated operations can make the first piston column 191 reciprocate left and right to push the support rod 181 intermittently to the right, and at the same time, with the use of the connecting spring 182, the filter assembly 18 can be automatically driven to move back and forth left and right, thereby making the filter assembly 18 The filter assembly 18 generates a certain shaking force, which is convenient for shaking off the impurities on the surface of the filter assembly 18 to avoid affecting the filtering operation of the filter assembly 18. Then the filtered hydrogen fuel can enter the anode of the hydrogen fuel cell body 10 through the pipeline and the connecting pipe 27. At this time, the blower 12 is started, and the blower 12 allows the outside air to enter the cathode of the hydrogen fuel cell body 10 through the air inlet pipe 4. Inside the hydrogen fuel cell body 10, hydrogen and oxygen undergo an electrochemical reaction to generate electrical energy and water. The electrical energy generated by the hydrogen fuel cell body 10 is distributed to the propulsion motor inside the right side of the hull 1 through the power management system, and then the propulsion motor drives the propeller 3 to propel the container ship to sail. Since this part is a prior art, it will not be introduced in detail here.

[0025] Embodiment 2: The low-carbon emission hydrogen fuel cell powered container ship in this embodiment, based on the embodiment 1, can not only recover the heat generated by the hydrogen fuel cell body 10, but also continue to reuse it, and at the same time can improve the preheating effect of the hydrogen fuel, and improve the overall performance and economy of the hydrogen fuel cell body 10. For the specific structure, please refer to the attached Figure 3-Figure 5 as well as Fig.11 As shown, the bottom surface of the hydrogen fuel cell body 10 is installed on the bottom plate 13 through the cooling base 11, and a preheater 8 is arranged on the bottom plate 13 between the filter 7 and the hydrogen fuel cell body 10. An insulation frame 9 is installed on the outside of the preheater 8, and the insulation frame 9 is installed on the bottom plate 13. The insulation frame 9 and the cooling base 11 are both arranged in a "U" shape and are hollow inside, which are used for water storage and waste heat recovery and reuse. A drainage pipe is installed on the bottom surface of the insulation frame 9, and a transmission vertical rod 24 is rotatably installed inside the rear side of the insulation frame 9. A water wheel mechanism 25 is fixed on the upper outer side of the transmission vertical rod 24. The middle outer side of the transmission vertical rod 24 is connected to the rear end of the transmission cross rod 26 installed in the preheater 8 through a group of bevel gear sets, and the front end of the transmission cross rod 26 is connected to a connecting pipe 27 that runs through the preheater 8 through another group of bevel gear sets. The connecting pipe 27 is rotatably connected to the pipes on the left and right sides through sealed bearings, and a drainage pipe is installed on the bottom surface of the insulation frame 9.

[0026] The water generated by the electrochemical reaction enters the hollow U-shaped cooling base 11 through a water pump to cool the hydrogen fuel cell body 10 and recover the heat at the same time. Then, the water recovered from the cooling base 11 enters the hollow U-shaped insulation frame 9 through a pipe, so that the water in the insulation frame 9 can insulate the outside of the preheater 8 to prevent the heat in the preheater 8 from diffusing outward. At the same time, the preheater 8 is turned on, and the heating wire in the preheater 8 generates a certain amount of heat to heat the inside of the connecting pipe 27. The hydrogen fuel is preheated, and the water in the insulation frame 9 is discharged through the bottom pipe later. At the same time, the water in the insulation frame 9 drives the water wheel mechanism 25 and the transmission vertical rod 24 to rotate, and then the transmission vertical rod 24 drives the transmission cross rod 26 to rotate through the bevel gear assembly, and the transmission cross rod 26 drives the connecting pipe 27 to rotate through the bevel gear assembly, so that when the connecting pipe 27 rotates, the hydrogen fuel in the connecting pipe 27 can be evenly preheated, thereby improving the preheating effect and improving the overall performance and economy of the hydrogen fuel cell body 10.

[0027] Embodiment 3: The low-carbon emission hydrogen fuel cell powered container ship in this embodiment is based on the embodiment 1, and it is convenient to separate the supporting frame 17 from the mounting frame 14, so as to facilitate the disassembly and replacement of the supporting frame 17 at a later stage. The specific structure is shown in the attached Figure 5 And attached Figure 12-13 As shown, a bidirectional screw rod 281 and a guide rod 282 are installed inside the mounting frame 14, and the outer sides of the left and right ends of the bidirectional screw rod 281 are threadedly connected with a fixing block 28 in a "7" shape structure, and a guide rod 282 is installed inside the fixing block 28. One end of the fixing block 28 is inserted into the supporting frame 17, and the bottom of the supporting frame 17 is matched with the groove on the top of the mounting frame 14. A cover plate 201 is rotatably installed inside the left side of the deck 2, and the length and width of the cover plate 201 are respectively larger than the length and width of the corresponding supporting frame 17 arranged below.

[0028] When the hydrogen fuel in the hydrogen storage tank 5 is used up and needs to be replaced, the cover plate 201 is turned to open, and then the bidirectional screw rod 281 is manually rotated. When the bidirectional screw rod 281 rotates, it drives the "7"-shaped fixed block 28 connected by the outer threads at the left and right ends to move outward, and the stable movement of the fixed block 28 is ensured by the guide rod 282. When the fixed block 28 moves to a position separated from the supporting frame 17, the rotation of the bidirectional screw rod 281 is stopped, and the pipeline on the front side of the hydrogen storage tank 5 is separated from the pipeline on the front side of the conveying control mechanism 6. Then, the supporting frame 17 can be moved upward by a crane or other equipment, so that the supporting frame 17 is separated from the mounting frame 14, and the supporting frame 17 and the hydrogen storage tank 5 are moved out of the hull 1 for replacement, which is convenient to operate.
