Description

Technical Field

[0001] The utility model relates to the field of hydrogen supply devices for ships, in particular to a safe hydrogen supply device for ships. Background Art

[0002] Hydrogen supply to ships mainly refers to the process of providing hydrogen supply to ships that use hydrogen energy as propulsion power. There are two main ways to apply hydrogen as an energy source on ships: one is to apply it to traditional internal combustion engines, including pure hydrogen internal combustion engines or mixed-burning internal combustion engines used with fuels such as ammonia / methanol; the other is to apply it to a new type of power device - fuel cells. For ships sailing on the water, using water electrolysis to produce hydrogen is a more appropriate method.

[0003] The water is purified and then electrolyzed while heated, turning water molecules into hydrogen molecules and oxygen molecules, which are then purified for use. Since hydrogen is relatively dangerous and prone to explosion, ships try to use it as soon as it is produced. When danger occurs, the power is immediately cut off and hydrogen production is stopped. However, there will still be a certain amount of hydrogen in the hydrogen transportation process, posing a major safety hazard. Utility Model Content

[0004] The main purpose of the utility model is to provide a safe hydrogen supply device for ships, which can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a safe hydrogen supply device for ships, including a hydrogen production device and a hydrogen use device, a transmission barrel is arranged between the hydrogen production device and the hydrogen use device, the transmission barrel is respectively connected to the hydrogen production device and the hydrogen use device through a transmission pipeline, an electromagnetic valve is installed at the end of the transmission pipeline, the transmission barrel is made of copper oxide, and a heating component is installed on the surface of the transmission barrel.

[0006] The heating component comprises a resistance ring, which is spirally wound on the surface of the transmission barrel. A power supply is arranged on the outside of the transmission barrel, and the power supply provides current to the resistance ring.

[0007] A plurality of support rods are arranged at the bottom of the transmission barrel, the power supply is located below the transmission barrel, an explosion-proof barrel is arranged outside the transmission barrel, and the transmission barrel, the power supply and the resistance ring are all located inside the explosion-proof barrel.

[0008] The transmission pipeline is used to output hydrogen and is arranged vertically upward.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. In the utility model, by setting a transmission barrel and a solenoid valve, when a problem occurs in the hydrogen-using device or the external use environment, the solenoid valve receives a command to close quickly, the power circuit of the hydrogen-producing device is also quickly disconnected, and the transmission barrel is heated. Since the transmission barrel is made of copper oxide, it has good thermal conductivity. When the temperature reaches a certain level, hydrogen will quickly react with copper oxide to produce non-dangerous copper metal and water, thereby ensuring the safety of the use environment.

[0011] 2. In the present invention, by setting a resistance ring and a power supply, since the resistance ring is wound around the surface of the transmission barrel, when the current passes through the resistance ring, the transmission barrel can be quickly heated. At the same time, according to the heat calculation formula: Q = I 2 RT, as the current gradually increases, the heat will increase at a square multiple, and the greater the resistance, the more heat will be generated. At this time, the time required to reach a certain heat will be reduced, so the transmission barrel can be heated quickly and the safety rate can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-4As shown, a safe hydrogen supply device for ships comprises a hydrogen production device 1 and a hydrogen using device 2. The hydrogen production device 1 selects water electrolysis to produce hydrogen, and also comprises a heating device and a river water or seawater purification device. A transmission barrel 3 is arranged between the hydrogen production device 1 and the hydrogen using device 2. The hydrogen generated by the hydrogen production device 1 first enters the interior of the transmission barrel 3, and then enters the interior of the hydrogen using device 2, so as to ensure that the hydrogen consumption of the hydrogen using device 2 can be properly adjusted. The transmission barrel 3 is respectively connected to the hydrogen production device 1 and the hydrogen using device 2 through a transmission pipeline 4. An electromagnetic valve 5 is installed at the end of the transmission pipeline 4. The electromagnetic valve 5 can be closed and opened after receiving an instruction. The transmission barrel 3 is made of copper oxide, and a heating component is installed on the surface of the transmission barrel 3.

[0019] After the hydrogen production device 1 produces hydrogen, it is transported to the interior of the transmission barrel 3 through the transmission pipeline 4, and then enters the interior of the hydrogen use device 2 for use through the transmission barrel 3 and another transmission pipeline 4. When a problem occurs in the hydrogen use device 2, or a problem occurs in the external use environment, the solenoid valve 5 receives an instruction to close quickly, the power circuit of the hydrogen production device 1 is also quickly disconnected, and the heating component is quickly started to heat the transmission barrel 3. Since the transmission barrel 3 is made of copper oxide, it itself has good thermal conductivity. When the temperature reaches a certain level, hydrogen will quickly react with copper oxide to produce non-hazardous copper metal and water, thereby ensuring the safety of the use environment.

[0020] The heating assembly includes a resistance ring 6 , which is spirally wound on the surface of the transmission barrel 3 . A power supply 7 is provided on the outside of the transmission barrel 3 , and the power supply 7 provides current to the resistance ring 6 .

[0021] Since the resistance ring 6 is wound around the surface of the transmission barrel 3, the power supply 7 is started, and when the current passes through the resistance ring 6, the entire resistance ring 6 can generate heat, and the transmission barrel 3 can be quickly heated at this time. At the same time, according to the heat calculation formula: Q = I 2 RT, as the current gradually increases, the heat will increase in multiples of the square, and the greater the resistance, the more heat will be generated. At this time, the time required to reach a certain heat will be reduced, so the rapid heating of the transmission barrel 3 can be guaranteed, and the safety rate can be improved.

[0022] A plurality of support rods 8 are provided at the bottom of the transmission barrel 3. In the present embodiment, three support rods 8 are provided, so that the transmission barrel 3 is at a certain height from the ground. The power supply 7 is located below the transmission barrel 3. An explosion-proof barrel 9 is provided outside the transmission barrel 3. The transmission barrel 3, the power supply 7 and the resistance ring 6 are all located inside the explosion-proof barrel 9. Since the hydrogen is located inside the transmission barrel 3, there is a risk of explosion. Therefore, the safety can be further improved by using the explosion-proof barrel 9.

[0023] The transmission pipeline 4 is used to output hydrogen and is arranged vertically upward. Since the density of hydrogen is much smaller than that of air, when hydrogen is produced, it will move out from above. Setting it in an upward direction can make it more convenient to collect and process the hydrogen.

[0024] It should be noted that the utility model is a safe hydrogen supply device for ships. When in use, the hydrogen produced by the hydrogen production device 1 is transported to the interior of the transmission barrel 3 through the transmission pipeline 4, and then enters the interior of the hydrogen use device 2 through the transmission barrel 3 and another transmission pipeline 4 for use. When a problem occurs in the hydrogen use device 2, or a problem occurs in the external use environment, the solenoid valve 5 receives an instruction to close quickly, the power circuit of the hydrogen production device 1 is also quickly disconnected, and the power supply 7 is started. When current passes through the resistance ring 6, the entire resistance ring 6 can generate heat, and the transmission barrel 3 can be quickly heated at this time. Since the transmission barrel 3 is made of copper oxide, it itself has good thermal conductivity. When the temperature reaches a certain level, hydrogen will quickly react with copper oxide to produce non-dangerous copper metal and water, thereby ensuring the safety of the use environment.

[0025] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
