Description

TECHNICAL FIELD

[0001] The application relates to the technical field of container ships, in particular to a hydrogen fuel emission reduction type container ship. BACKGROUND

[0002] Ship transportation is an important pillar of global trade, and the carbon emissions of the global shipping industry account for 3% of the total global carbon emissions. Hydrogen fuel is used as a power source to control the propulsion device in the ship, so that the ship can reduce greenhouse gas emissions when driving and avoid polluting the environment.

[0003] For example, the patent with the patent name "zero-carbon emission container ship" disclosed in the prior art with the publication number "CN117208187A" discloses that the hydrogen fuel storage module and the container cargo are separated by a separation area, which can maximize the guarantee that the hydrogen fuel will not affect the front cargo in the event of leakage, fire and other accidents. The hydrogen fuel storage module is designed as a container type and is directly installed in the open area behind the separation area. When the ship is in port, it can directly perform the box changing operation, saving the fuel filling step. At the same time, a matching hydrogen fuel preparation room and hydrogen fuel joint place are arranged in the separation area to deliver hydrogen fuel to the hydrogen fuel cell module. The ship is also provided with an electric energy storage module, which is also designed as a container type, facilitating direct box changing operation and being arranged behind the separation area as a supplementary power source. The patent with the patent name "hydrogen energy ship" disclosed in the prior art with the publication number "CN115009497A" discloses that a hydrogen pressure sensing element is used to detect the pressure value of hydrogen in the fuel cell and transmit it to the control chip. When the detected hydrogen pressure value is lower than the preset range value, the control chip sends an alarm signal through the alarm device and closes the above-mentioned electromagnetic valve. In this way, the hydrogen pressure value in the hydrogen pipeline can be avoided to be too low or too high, so that the operator cannot discover and take corresponding measures in time, thereby causing the delivered hydrogen to fail to meet the demand as fuel and causing the risk of fuel cell rupture. The air compressor and hydrogen tank can respectively provide air and hydrogen for the fuel cell to generate electric energy, and then the electric system can supply power to the control system and the storage battery of the ship body, thereby driving the ship to travel, realizing the mode of driving the ship by hydrogen as energy, and avoiding the situation that the exhaust emission of the ship does not meet the standard requirements.

[0004] The hydrogen fuel emission reduction type container ship in the prior art is directly supplied with external air by an air compressor to generate electric energy by the hydrogen fuel cell body, but the temperature of the air after passing through the air compressor is about 150 DEG C, and if the air with high temperature is directly supplied to the hydrogen fuel cell body, the thermal load of the hydrogen fuel cell body is increased, thereby affecting the oxygen concentration and reaction efficiency of the hydrogen fuel cell body, and thus affecting the propulsion operation of the ship in the later period.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the application.

[0036] Please refer to Figures 1-13 The application provides the following technical solutions: ​

[0037] Example 1: In this example, the hydrogen fuel cell container ship with reduced emissions utilizes a cold source to lower the temperature of the bottom plate 7 itself and its surrounding area. This low temperature on the surface and around the bottom plate 7 pre-cools the air entering the hydrogen fuel cell body 8, reducing the heat load on the hydrogen fuel cell body 8, increasing the oxygen concentration and reaction efficiency, and preventing any impact on subsequent ship propulsion operations. The specific structure is shown in the attached diagram. Figures 1-6 As shown, the vessel includes a hull 1 and a deck 2 installed inside it for placing containers. A propeller 3 is installed on the left side of the bottom of the hull 1. An air inlet pipe 4 connected to a blower is installed through the front side of the hull 1. A bottom plate 7 is installed inside the hull 1. A lithium battery pack 9, a hydrogen fuel cell body 8, a delivery control mechanism 6, a hydrogen storage tank assembly 5, and a shielding and sealing assembly are installed on the top of the bottom plate 7 from left to right. A processing chamber 72 is opened in the bottom plate 7 below the hydrogen storage tank assembly 5. One end of a first air supply pipe 41 connected to the other end of the blower is inserted into the processing chamber 72. A second air supply pipe 10 is connected through the rear side of the processing chamber 72 and connected to the hydrogen fuel cell body 8. A cover plate 201 is rotatably installed inside the deck 2 via a rotating rod 202. Two sets of connecting ropes 2 are symmetrically wound around the outside of the rotating rod 202. 03. Inside the processing chamber 72, a W-shaped guide plate 13 is installed, and four sets of staggered guide holes 131 are opened inside the guide plate 13. The pipe on the outside of the hydrogen storage tank assembly 5 is connected to the delivery control mechanism 6 through the connecting pipe 61. The delivery control mechanism 6 is connected to the hydrogen fuel cell body 8 through the pipe. A cold source is installed on the inner wall of the shielding and sealing assembly. The shielding and sealing assembly with a U-shaped structure is sleeved on the outside of the hydrogen storage tank assembly 5. The bottom surface of the shielding and sealing assembly is in close contact with the U-shaped storage groove 71 opened on the upper surface of the bottom plate 7. Four sets of guide rods 17 are symmetrically installed in the storage groove 71. A return spring 171 is nested and connected to the outside of the guide rod 17. One end of the guide rod 17 is slidably connected to the inside of the side protective plate 11. The top surface of the shielding and sealing assembly is in close contact with the bottom surface of the cover plate 201.

[0038] The cold source installed on the inner side of one of the corner guards 12 of the shielding and sealing assembly is started first. The cold source can be a refrigerating machine. The cold source generates and releases a certain amount of cold air. This not only keeps the periphery of the hydrogen storage tank assembly 5 inside the shielding and sealing assembly at a low temperature, thereby improving the safety of the hydrogen storage tank assembly 5 during use, but also lowers the temperature of the bottom plate 7 and the periphery of the bottom plate 7. The shielding and sealing assembly shields the periphery of the hydrogen storage tank assembly 5, preventing the cold air from spreading outward, thereby facilitating the use of the hydrogen storage tank assembly 5. Then the hydrogen fuel in the hydrogen storage tank assembly 5 is delivered to the anode of the hydrogen fuel cell body 8 through the connecting pipe 61 and the delivery control mechanism 6. The front end of the air inlet pipe 4 is connected to the air compressor and the dehumidifier outside. Then the air blower above the bottom plate 7 is started. The outside air is first dehumidified by the dehumidifier and then enters the air compressor. The air is compressed by the air compressor. This dehumidifies the air first and then compresses it, which can reduce the generation of condensed water and reduce the subsequent drying load. At this time, the temperature of the compressed air may rise to about 150°. (At this time, the compressed high-temperature air cannot be directly delivered to the hydrogen fuel cell body 8 to avoid affecting the performance and efficiency of the hydrogen fuel cell body 8.) Then the compressed air enters the air blower through the air inlet pipe 4. The air enters the first air supply pipe 41 above the bottom plate 7 through the air blower. Then the air in the first air supply pipe 41 enters the processing cavity 72 inside the bottom plate 7. At this time, the cold air generated by the cold source inside the shielding and sealing assembly also makes the temperature of the surface of the bottom plate 7 and the surrounding temperature relatively low. Then the low temperature of the surface of the bottom plate 7 automatically pre-cools the air in the processing cavity 72. The material of the corresponding part of the bottom plate 7 above the processing cavity 72 can be copper, which can improve the heat conduction efficiency. The "W"-shaped flow guide plate 13 and the flow guide hole 131 installed in the processing cavity 72 cooperate to make the air flow in a "W" shape in the processing cavity 72, which can prolong the flow path of the air in the processing cavity 72, thereby further improving the efficiency and quality of the air pre-cooling. (Since the dehumidifier has been used to remove the moisture in the air, and the temperature of the surface of the bottom plate 7 is not extremely low, the air in the processing cavity 72 will not freeze and affect the transmission efficiency of the oxygen.) Then the pre-cooled air enters the cathode of the hydrogen fuel cell body 8 through the second air supply pipe 10 and the air flow control mechanism, thereby avoiding increasing the thermal load of the hydrogen fuel cell body 8. (The air flow control mechanism can well control the air supply amount to avoid insufficient air supply, which affects the electrochemical reaction efficiency, and also avoids excessive air supply, which increases energy consumption. Since the air flow control mechanism is prior art, it will not be described in detail here.) Then the hydrogen and oxygen in the hydrogen fuel cell body 8 undergoes electrochemical reaction to generate electricity and water. The water is discharged through the pipeline at the bottom of the ship body 1 later.The electric energy generated by the hydrogen fuel cell body 8 is distributed to the propelling motor on the right side of the ship body 1 through the power management system, and then the propelling motor drives the propeller 3 to propel the container ship to sail, so that the main power source composed of two hydrogen fuel cell bodies 8 and lithium battery groups 9 provides power for the container ship and domestic electricity, and since this part is prior art, it is not described in detail here.

[0039] At the same time, multiple water spraying pipes and hydrogen detectors can be installed on the inner side of the corner protection plate 12 in the shielding and sealing assembly. When the hydrogen detector detects that the hydrogen concentration in the shielding and sealing assembly reaches a certain value, it means that hydrogen leakage has occurred. This signal can be transmitted to the central processing module, and the central processing module controls the alarm to issue an alarm. At this time, the staff can handle the leaked hydrogen. When a fire occurs, the water spraying pipe can spray water to extinguish the fire. Since this part is prior art, it is not described in detail here.

[0040] Example two: The hydrogen fuel emission reduction type container ship in this embodiment is based on example one, which is convenient for automatically expanding the shielding and sealing assembly outward, thereby avoiding affecting the later hoisting and replacement operation of the hydrogen storage tank assembly 5. For specific structure, please refer to the drawings Figures 7-12 At the same time, the hydrogen storage tank assembly 5 and the mounting frame 15 can also be automatically disassembled and separated, which further facilitates the hoisting and replacement operation of the hydrogen storage tank assembly 5, and can shorten the time spent on replacement. For specific structure, please refer to the drawings Figures 4-5 and the drawings Figure 12 and the drawings Figure 13As shown, the shielding sealing assembly is composed of four groups of edge protection plates 11 and corner protection plates 12, the cold source is installed on the inner side of one of the corner protection plates 12 in the shielding sealing assembly, the outer side of both ends of the corner protection plate 12 is provided with a "T"-shaped clamping groove 121, the clamping groove 121 is internally provided with a connecting spring 122, the inner side wall of the edge protection plate 11 is symmetrically provided with a clamping block 111 which is clamped and slidingly connected with the clamping groove 121, and one side surface of the clamping block 111 is connected with the connecting spring 122, the edge protection plate 11 and the clamping block 111 are both provided in a "T" shape, the corner protection plate 12 is provided in an "L" shape, four groups of vertical rods 14 are internally and correspondingly installed in the bottom plate 7 below the corner protection plate 12, and the outer side of the vertical rod 14 is provided with an expansion control plate 141 which is arranged in a groove in the bottom plate 7, the outer side of the fan-shaped expansion control plate 141 is correspondingly provided with the corner protection plate 12, the corner protection plate 12 forms a sliding structure through the expansion control plate 141, the lower ends of the two connecting ropes 203 are internally and correspondingly installed in the bottom plate 7, and then are connected with the two vertical rods 14 on the right side through a guide wheel, a transmission structure is formed between the vertical rod 14 on the left side and the vertical rod 14 on the right side through a sprocket assembly 142, the outer sides of the two vertical rods 14 on the right side are both nested with a spiral spring 143, the upper end of the spiral spring 143 is connected with the bottom surface of the bottom plate 7, the inner sides of the two edge protection plates 11 on the left and right sides are fixedly provided with a connecting plate 16, the inner side of the connecting plate 16 is fixedly provided with a protruding rod 161, the mounting bracket 15 above the bottom plate 7 is connected with the bottom surface of the hydrogen storage tank assembly 5 in a concave-convex matching manner, and one end of the protruding rod 161 is inserted into the hole internally and correspondingly arranged in the mounting bracket 15 and the hydrogen storage tank assembly 5 on the left and right sides.

[0041] When it is necessary to hoist and replace the hydrogen storage tank assembly 5 inside the container ship, manually rotate the cover plate 201 by 180° to open it at this time. At this time, the cover plate 201 drives the rotating rod 202 to rotate. When the rotating rod 202 rotates, it pulls and winds one end of the connecting rope 203. Then, the lower end of the connecting rope 203 automatically drives the corresponding vertical rod 14 to rotate. When the vertical rod 14 rotates, it drives the corresponding vertical rod 14 to rotate through the sprocket assembly 142. Thus, the four vertical rods 14 rotate simultaneously. At this time, the four vertical rods 14 simultaneously drive the four expansion control plates 141 to rotate 180°. When the fan-shaped expansion control plate 141 rotates, it will exert an outward thrust on the corner protection plate 12 at the corresponding position. Then, while the corner protection plate 12 slides with the side protection plate 11, it带动边部防护板11一同向外移动,此时边部防护板11内侧的呈“T”形的卡接块111在角部防护板12外侧的卡接槽121内滑动,同时对连接弹簧122挤压蓄力,同时边部防护板11在导向杆17的外侧滑动,对复位弹簧171挤压蓄力,因此使得四组边部防护板11和角部防护板12组成的呈“回”字形结构的遮挡密封组件在储存凹槽71内向外移动扩张展开,继而使得遮挡密封组件的长度和宽度均变大,因此使得遮挡密封组件的内侧与氢气存储罐组件5之间的间距增大,同时左右两侧的边部防护板11向外移动时会带动连接板16和凸杆161一同向外移动,使得凸杆161从安装架15的左右两侧内的孔洞内向外拔出,从而解除安装架15与氢气存储罐组件5的安装结构,接着将氢气存储罐组件5外侧的管道与连接管61分离,然后便可通过吊装机构将氢气存储罐组件5从遮挡密封组件内快速的吊装出来进行更换了,从而完成一系列工作。

It should be noted that there seems to be some garbled text in the original Chinese for the part "带动边部防护板11一同向外移动" which is translated as "带动边部防护板11一同向外移动" in the English translation. It might need to be corrected in the original Chinese text for a more accurate translation.
