Description

Technical Field

[0001] The present invention relates to the technical field of container ships, and specifically to a hydrogen fuel emission reduction type container ship. Background Art

[0002] Shipping is an important pillar of global trade. The carbon emissions of the global shipping industry account for 3% of the global total carbon emissions. Using hydrogen fuel as a power source to control the propulsion device on the ship can reduce greenhouse gas emissions during ship operation and avoid environmental pollution. For example, in the prior art, the patent with the publication number "CN117208187A" and the patent name "A zero-carbon emission container ship" discloses that the hydrogen fuel storage module and the container cargo are separated by a partition area, which can ensure to the greatest extent that in the event of accidents such as hydrogen fuel leakage and fire, the goods in front will not be affected. The hydrogen fuel storage module is designed in a container form and is directly installed in the open area behind the partition area. When docking at the port, the container can be directly replaced, eliminating the step of refueling. At the same time, a supporting hydrogen fuel preparation room and a hydrogen fuel connection point are arranged in the partition area to transport hydrogen fuel to the hydrogen fuel cell module. This ship is also provided with an electric energy storage module, which is also designed in a container form for convenient direct container replacement operation and is arranged behind the partition area as a supplementary power source. And in the prior art, the patent with the publication number "CN115009497A" and the patent name "A hydrogen energy ship" discloses that a hydrogen pressure sensing element is used to detect the hydrogen pressure value in the fuel cell stack 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 solenoid valve, so as to avoid the situation that the hydrogen pressure value in the hydrogen pipeline is too low or too high and the operator cannot detect it in time and take corresponding measures, resulting in the hydrogen delivered not meeting the fuel demand and the risk of fuel cell stack rupture. Air and hydrogen can be provided to the fuel cell stack by an air compressor and a hydrogen tank respectively to generate electric energy by the fuel cell stack, and then the electric energy system supplies power to the control system and battery of the ship hull, and then drives the ship to sail, realizing the method of driving the ship with hydrogen as the energy source and avoiding the situation that the exhaust emissions of the ship do not meet the standard requirements.

[0003] When the hydrogen fuel emission reduction type container ship in the above-mentioned prior art is in use, the air outside is directly transported to the hydrogen fuel cell body through an air compressor to facilitate the generation of electric energy by the hydrogen fuel cell body in the later stage. However, when the air passes through the air compressor, the temperature will rise to about 150 °C. If the air with a higher temperature is directly transported to the hydrogen fuel cell body, this will increase the thermal load of the hydrogen fuel cell body, and then affect the oxygen concentration and reaction efficiency of the hydrogen fuel cell body. Therefore, it will affect the propulsion operation of the ship in the later stage. So we propose a hydrogen fuel emission reduction type container ship to solve the problems raised above. Summary of the Invention

[0004] The purpose of the present invention is to provide a hydrogen fuel emission reduction type container ship to solve the problem in the above background technology that when the container ship on the current market directly transports the air with a higher temperature to the hydrogen fuel cell body, this will increase the thermal load of the hydrogen fuel cell body, and then affect the oxygen concentration and reaction efficiency of the hydrogen fuel cell body, so it will affect the propulsion operation of the ship in the later stage.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A hydrogen fuel emission reduction type container ship includes a hull and a deck installed above it for placing containers inside. And a propeller is installed on the left bottom surface of the hull. Moreover, an air inlet pipe connected to the blower inside it penetrates through the front side surface of the hull. A bottom plate is installed inside the hull. Above the bottom plate, a lithium battery pack, a hydrogen fuel cell body, a conveying control mechanism, a hydrogen storage tank assembly and a shielding and sealing assembly are installed in sequence from left to right. And a processing chamber is opened in the bottom plate corresponding to the lower part of the hydrogen storage tank assembly. One end of the first air supply pipe connected to the other end of the blower penetrates and inserts into the processing chamber. The second air supply pipe connected to the rear side inside of the processing chamber is connected to the hydrogen fuel cell body. A cold source is installed on the inner side wall of the shielding and sealing assembly.

[0006] Preferably, a cover plate is rotatably installed inside the deck through a rotating rod, and two groups of connecting ropes are symmetrically wound around the outside of the rotating rod.

[0007] Preferably, a "W"-shaped flow guide plate is installed inside the processing chamber, and four groups of staggered flow guide holes are opened in the flow guide plate.

[0008] Preferably, the pipeline outside the hydrogen storage tank assembly is connected to the conveying control mechanism through a connecting pipe, and the conveying control mechanism is connected to the hydrogen fuel cell body through a pipeline.

[0009] Preferably, the shielding and sealing assembly in a "hui" character structure is sleeved outside the hydrogen storage tank assembly, and the bottom surface of the shielding and sealing assembly is in close contact with the storage groove in a "hui" character structure formed on the upper surface of the bottom plate. Four groups of guide rods are symmetrically installed in the storage groove, a return spring is nested and connected to the outside of the guide rod, and one end of the guide rod is slidably connected through the interior of the side protection plate.

[0010] Preferably, the shielding and sealing assembly is composed of four groups of side protection plates and a corner protection plate. The cold source is installed on the inner side surface of one of the corner protection plates inside the shielding and sealing assembly. "T"-shaped clamping grooves are formed on the outer side surfaces at both ends of the corner protection plate. A connecting spring is installed inside the clamping groove. Clamping blocks that are in clamping and sliding connection with the clamping groove are symmetrically installed on the inner side wall of the side protection plate, and one side surface of the clamping block is connected to the connecting spring. The top surface of the shielding and sealing assembly is in close contact with the bottom surface of the cover plate.

[0011] Preferably, the side protection plate and the clamping block are both in a "T" shape, and the corner protection plate is in an "L" shape.

[0012] Preferably, four groups of vertical rods are installed through the bottom plate corresponding to the lower part of the corner protection plate. An expansion control plate is installed on the outside of the vertical rod and is arranged in a groove inside the bottom plate. A corner protection plate is correspondingly arranged on the outside of the fan-shaped expansion control plate. The corner protection plate forms a sliding structure through the expansion control plate.

[0013] Preferably, the lower ends of the two connecting ropes both penetrate through the interior of the bottom plate and are then wound and connected to the two vertical rods on the right side through guide wheels. A transmission structure is formed between one vertical rod on the left side and one vertical rod on the right side through a sprocket assembly. Return springs are nested and connected to the outside of the two vertical rods on the right side, and the upper ends of the return springs are connected to the bottom surface of the bottom plate.

[0014] Preferably, connecting plates are fixed to the inner sides of the two side protection plates on the left and right sides. A convex rod is fixed to the inner side of the connecting plate. The mounting frame above the bottom plate is in concave-convex fit connection with the bottom surface of the hydrogen storage tank assembly, and one end of the convex rod is inserted into the holes formed in the left and right side surfaces of the mounting frame and the hydrogen storage tank assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This hydrogen fuel emission reduction type container ship can increase the oxygen concentration and reaction efficiency of the hydrogen fuel cell body, thereby improving the electrochemical efficiency of the hydrogen fuel cell body, reducing the heat load of the hydrogen fuel cell body, and avoiding affecting the later propulsion operation of the ship. The specific content is as follows: (1) Air from the outside is transported into the processing chamber through the first air supply pipe, facilitating the use of a cold source to lower the temperature of the bottom plate itself and its periphery. This enables pre-cooling of the air in the processing chamber through the low temperature on the surface and periphery of the bottom plate, so that the low-temperature air can increase the oxygen concentration and reaction efficiency of the hydrogen fuel cell body, thereby enhancing the electrochemical efficiency of the hydrogen fuel cell body, reducing the heat load of the hydrogen fuel cell body, and preventing it from affecting the later propulsion operation of the ship. Further, through the combined use of the flow guide plate in a "W" shape and the flow guide holes, the air in the processing chamber flows in a "W" shape, which can extend the flow path of the air in the processing chamber, and then further improve the efficiency and quality of air pre-cooling. (2) The shielding and sealing component can well shield and seal the periphery of the hydrogen storage tank component, reducing the loss of cold air around the hydrogen storage tank component, so that the hydrogen storage tank component can be placed and used well. At the same time, through the setting of the connecting rope, when the cover plate is opened, the vertical rod and the expansion control plate can be automatically driven to rotate. Thus, when the four fan-shaped expansion control plates rotate, they drive the four corner protection plates to move outward at the same time, and then the corner protection plates drive the four side protection plates to move outward, so that the shielding and sealing component composed of the side protection plates and the corner protection plates expands and unfolds well outward around the perimeter, facilitating increasing the distance between the hydrogen storage tank component and the shielding and sealing component later, and facilitating the later hoisting and replacement operation of the hydrogen storage tank component. (3) When the side protection plates on the left and right sides drive the connecting plate and the convex rod to move outward together, the convex rod is separated from the hole in the mounting frame, facilitating the automatic separation of the mounting frame from the hydrogen storage tank component, so as to facilitate the later hoisting and replacement operation of the hydrogen storage tank component. There is no need for staff to manually disassemble the hydrogen storage tank component, the operation is convenient, and the later replacement time is shortened. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 13 , the present invention provides the following technical solutions: Embodiment 1: In the hydrogen fuel emission reduction type container ship in this embodiment, a cold source can be used to lower the temperature of the bottom plate 7 itself and the periphery of the bottom plate 7, so that the air entering the hydrogen fuel cell body 8 is pre-cooled by the low temperature on the surface and periphery of the bottom plate 7. This can reduce the heat load of the hydrogen fuel cell body 8, improve the oxygen concentration and reaction efficiency of the hydrogen fuel cell body 8, and avoid affecting the later propulsion operation of the ship. The specific structure is referred to in the appendix Figures 1 - 6As shown in the figure, it includes a hull 1 and a deck 2 installed inside above it for placing containers. A thruster 3 is installed on the left bottom surface of the hull 1. An air inlet pipe 4 connected to the blower inside the hull 1 penetrates through the front side surface of the hull 1. A bottom plate 7 is installed inside the hull 1. Above the bottom plate 7, a lithium battery pack 9, a hydrogen fuel cell body 8, a conveying control mechanism 6, a hydrogen storage tank assembly 5, and a shielding and sealing assembly are installed in sequence from left to right. A treatment chamber 72 is opened in the bottom plate 7 corresponding to the lower part of the hydrogen storage tank assembly 5. One end of a first air supply pipe 41 connected to the other end of the blower penetrates and is inserted into the treatment chamber 72. A second air supply pipe 10 connected to the rear side inside of the treatment chamber 72 is connected to the hydrogen fuel cell body 8. A cover plate 201 is rotatably installed inside the deck 2 through a rotating rod 202. Two groups of connecting ropes 203 are symmetrically wound around the outer side of the rotating rod 202. A guide plate 13 in a "W" shape is installed inside the treatment chamber 72, and four groups of staggered diversion holes 131 are opened in the guide plate 13. The pipeline outside the hydrogen storage tank assembly 5 is connected to the conveying control mechanism 6 through a connecting pipe 61, and the conveying control mechanism 6 is connected to the hydrogen fuel cell body 8 through a pipeline. A cold source is installed on the inner side wall of the shielding and sealing assembly. The shielding and sealing assembly in a "hui" - shaped structure is sleeved outside the hydrogen storage tank assembly 5. The bottom surface of the shielding and sealing assembly is in close contact with a storage groove 71 in a "hui" - shaped structure opened on the upper surface of the bottom plate 7. Four groups of guide rods 17 are symmetrically installed in the storage groove 71. A return spring 171 is nested on the outer side of the guide rod 17. One end of the guide rod 17 penetrates and slides inside the side protection plate 11. The top surface of the shielding and sealing assembly is in close contact with the bottom surface of the cover plate 201.

[0020] First, start the cold source (which can be a refrigerating machine) installed on the inner side of one of the corner protection plates 12 within the shielding and sealing assembly. At this time, the cold source generates and emits 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, facilitating the improvement of the safety during the use of the hydrogen storage tank assembly 5, but also reduces the temperature of the bottom plate 7 itself and the periphery of the bottom plate 7. At the same time, the shielding and sealing assembly shields the periphery of the hydrogen storage tank assembly 5, preventing the cold air from diffusing outward and facilitating the good use of the hydrogen storage tank assembly 5. Then, the hydrogen fuel in the hydrogen storage tank assembly 5 is transported to the anode in the hydrogen fuel cell body 8 through the connecting pipe 61 and the conveying control mechanism 6. At the same time, the front end of the air inlet pipe 4 is connected to an external air compressor and dehumidifier. Then, start the blower above the bottom plate 7, so that the external air is first dehumidified by the dehumidifier and then enters the air compressor. By compressing the air with the air compressor, dehumidifying the air first and then compressing it can reduce the generation of condensed water and lower 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 transported into 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 blower through the air inlet pipe 4. The air passes through the blower and enters the first air supply pipe 41 above the bottom plate 7. Then, the air in the first air supply pipe 41 enters the processing chamber 72 opened 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 its periphery relatively low. Then, the air in the processing chamber 72 is automatically pre-cooled by the low temperature on the surface of the bottom plate 7. The material of the corresponding part of the bottom plate 7 above the processing chamber 72 can be copper material, so as to improve the heat conduction efficiency. At the same time, through the cooperation of the flow guide plate 13 in the shape of "W" and the flow guide holes 131 installed in the processing chamber 72, the air flows in a "W" shaped trajectory in the processing chamber 72, which can extend the flow path of the air in the processing chamber 72, and then further improve the efficiency and quality of the air pre-cooling. (Since the moisture in the air has been removed by the dehumidifier in the above process and the temperature of the surface of the bottom plate 7 is not extremely low, the air in the processing chamber 72 will not condense into ice and affect the oxygen transmission efficiency). Then, the pre-cooled air enters the cathode in the hydrogen fuel cell body 8 through the second air supply pipe 10 and the air flow rate control mechanism, avoiding increasing the heat load of the hydrogen fuel cell body 8. (The air flow rate control mechanism can well control the air supply volume, avoiding insufficient air supply volume resulting in insufficient oxygen in the hydrogen fuel cell body 8 and affecting the electrochemical reaction efficiency, and also avoiding excessive air supply volume increasing the energy consumption. Since the air flow rate control mechanism is a prior art, it will not be introduced in detail here). Then, the hydrogen and oxygen in the hydrogen fuel cell body 8 undergo an electrochemical reaction to generate electric energy and water. Later, the water is discharged through the pipeline at the bottom of the hull 1.The electric energy generated by the hydrogen fuel cell body 8 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 push the container ship to sail. Therefore, the main power supply is jointly composed of two hydrogen fuel cell bodies 8 and the lithium battery pack 9 to provide power and domestic electricity for the container ship. Since this part is prior art, no detailed introduction will be given here.

[0021] Meanwhile, a plurality of water spray pipes and hydrogen detectors can be installed inside 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 indicates that hydrogen leakage has occurred. This signal can be transmitted to the central processing module, and the central processing module controls the alarm to sound an alarm. At this time, the staff can deal with the leaked hydrogen. When a fire breaks out, the water spray pipes can spray water to extinguish the fire. Since this part is prior art, no detailed introduction will be given here.

[0022] Embodiment 2: In the hydrogen fuel emission reduction type container ship of this embodiment, on the basis of Embodiment 1, it is convenient to automatically unfold the shielding and sealing assembly outward, so as to avoid affecting the later hoisting and replacement operation of the hydrogen storage tank assembly 5. The specific structure is referred to in the attached Figures 7 - 12 figure. Meanwhile, the hydrogen storage tank assembly 5 and the mounting frame 15 can 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. The specific structure is referred to in the attached Figures 4 - 5 and the attached Figure 12 and the attached Figure 13As shown in the figure, the shielding and sealing assembly is composed of four groups of side protection plates 11 and corner protection plates 12. The cold source is installed on the inner side surface of one of the corner protection plates 12 inside the shielding and sealing assembly. On the outer side surfaces at both ends of the corner protection plate 12, "T"-shaped clamping grooves 121 are provided. Inside the clamping grooves 121, connecting springs 122 are installed. On the inner side walls of the side protection plates 11, clamping blocks 111 that are engaged and slidably connected with the clamping grooves 121 are symmetrically installed. One side surface of the clamping block 111 is connected to the connecting spring 122. The side protection plates 11 and the clamping blocks 111 are both arranged in a "T" shape, and the corner protection plate 12 is arranged in an "L" shape. Four groups of vertical rods 14 are installed through the bottom plate 7 corresponding to the lower part of the corner protection plate 12. On the outer side of the vertical rods 14, expansion control plates 141 arranged in the grooves inside the bottom plate 7 are installed. The outer side of the fan-shaped expansion control plate 141 corresponds to 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 both penetrate through the inside of the bottom plate 7 and are then wound around the two vertical rods 14 on the right side through guide wheels. Between one vertical rod 14 on the left side and one vertical rod 14 on the right side, a transmission structure is formed through a sprocket assembly 142. And on the outer sides of the two vertical rods 14 on the right side, scroll springs 143 are nested and connected. The upper ends of the scroll springs 143 are connected to the bottom surface of the bottom plate 7. On the inner sides of the two side protection plates 11 on the left and right sides, connecting plates 16 are fixed. On the inner sides of the connecting plates 16, convex rods 161 are fixed. The mounting frame 15 above the bottom plate 7 is in concave-convex fit connection with the bottom surface of the hydrogen storage tank assembly 5. And one end of the convex rod 161 is inserted into the holes opened in the left and right side surfaces of the mounting frame 15 and the hydrogen storage tank assembly 5.

[0023] When it is necessary to lift 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. Subsequently, 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 by 180°. When the fan-shaped expansion control plate 141 rotates, it exerts 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 drives the side protection plate 11 to move outward together. At this time, the "T"-shaped clamping block 111 on the inner side of the side protection plate 11 slides in the clamping groove 121 on the outer side of the corner protection plate 12, and simultaneously squeezes and stores energy in the connecting spring 122. At the same time, the side protection plate 11 slides on the outer side of the guide rod 17, and squeezes and stores energy in the return spring 171. Therefore, the shielding and sealing assembly in the shape of a "hui" character composed of the four side protection plates 11 and the corner protection plate 12 moves outward and expands in the storage groove 71. Subsequently, the length and width of the shielding and sealing assembly both increase. Therefore, the distance between the inner side of the shielding and sealing assembly and the hydrogen storage tank assembly 5 increases. At the same time, when the side protection plates 11 on the left and right sides move outward, they will drive the connecting plate 16 and the convex rod 161 to move outward together, so that the convex rod 161 is pulled out from the holes inside the left and right sides of the mounting frame 15, thereby releasing the mounting structure between the mounting frame 15 and the hydrogen storage tank assembly 5. Then, separate the pipeline outside the hydrogen storage tank assembly 5 from the connecting pipe 61. Then, the hydrogen storage tank assembly 5 can be quickly lifted out from the shielding and sealing assembly by the lifting mechanism for replacement, thus completing a series of work.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
