Description

Technical Field

[0001] The present application relates to the field of hydrogen energy application, and in particular to an intelligent chassis-borne hydrogen energy power generation system. Background Art

[0002] As fossil fuel consumption continues to increase, reserves are dwindling. These resources and energy sources will eventually become depleted, creating an urgent need to find a new, abundant energy source that doesn't rely on fossil fuels. Hydrogen is precisely such a secondary energy source. Hydrogen is a gas at room temperature and pressure, but a liquid at ultra-low temperatures and high pressures, making it an ideal new energy source. Currently, hydrogen is primarily stored in high-pressure cylinders and transported through pipelines. High-pressure cylinders placed in vehicles can supply hydrogen to fuel cells, in factories to other equipment, and assembled in boxes to provide hydrogen resources for fuel cell backup power or power stations.

[0003] When high-pressure gas cylinders containing hydrogen are used to supply gas to power stacks in factories or power stations, ensuring the safety of the gas supply is crucial. If hydrogen leaks occur, they can easily lead to serious safety accidents if not promptly addressed. However, currently, when a hydrogen leak occurs, safety officers are required to enter the site to troubleshoot and address the problem. If the hydrogen concentration in the factory or power station reaches a certain level, this poses a significant safety hazard to the officers entering the site. Summary of the Invention

[0004] When hydrogen in a high-pressure gas cylinder leaks, in order to ensure the personal safety of the safety officer, the present application provides an intelligent chassis carrying a hydrogen power generation system.

[0005] This application provides an intelligent chassis-mounted hydrogen power generation system, which adopts the following technical solutions:

[0006] An intelligent chassis-mounted hydrogen power generation system includes:

[0007] Intelligent chassis carrying transport module, used to carry and transport high-pressure gas cylinders;

[0008] An intelligent navigation module, used to control the intelligent chassis carrying the transport module to travel along a preset route;

[0009] The access network connection module is used to connect the pipeline of the high-pressure gas cylinder to the gas inlet of the fuel cell stack;

[0010] A hydrogen safety monitoring module is used to monitor the hydrogen concentration in the environment in real time. When the hydrogen concentration monitored by the hydrogen safety monitoring module reaches a trigger condition, the hydrogen safety monitoring module sends a trigger signal to control the intelligent navigation module to start;

[0011] The hydrogen maintenance room is used to be set at a position that maintains a safe distance from the fuel cell stack. The hydrogen maintenance room can be used as the end point of the preset route of the intelligent navigation module.

[0012] By adopting the above technical solution, when a high-pressure gas cylinder leaks, the hydrogen concentration in the environment will continue to rise. When the hydrogen safety monitoring module detects that the hydrogen concentration in the environment has reached the trigger condition, the intelligent navigation module will be activated under the control of the trigger signal sent by the hydrogen safety monitoring module. At this time, the intelligent chassis carrying and transporting module will, under the guidance of the intelligent navigation module, move the high-pressure gas cylinder away from the fuel cell stack along the preset route to disconnect the access network connection module; finally, the intelligent chassis carrying and transporting module will automatically drive to the hydrogen maintenance room; since there is a gap between the hydrogen maintenance room and the fuel cell stack, A safe distance is maintained, which can greatly reduce the probability of the leaking high-pressure gas cylinder reacting with the fuel cell stack and causing an explosion, ensuring the personal safety of the safety officer. In addition, the safety officer does not need to enter the leakage site to repair the high-pressure gas cylinder. He only needs to wait in the hydrogen maintenance room for the intelligent chassis carrying transportation module to deliver the high-pressure gas cylinder. By removing the leaking high-pressure gas cylinder from the accident site, the continuous increase in the hydrogen concentration value at the accident site can be effectively suppressed, ensuring the safety of the accident site. The entire high-pressure gas cylinder transportation process is completed fully automatically, realizing unmanned and intelligent management, and ensuring the life safety of the safety officer.

[0013] Optionally, a high-pressure gas cylinder leakage-proof module is used to seal the cover on the outside of the high-pressure gas cylinder, and a hollow interlayer is formed between the high-pressure gas cylinder leakage-proof module and the high-pressure gas cylinder, and the hollow interlayer is filled with inert gas.

[0014] By adopting the above technical solution, when a high-pressure gas cylinder leaks hydrogen due to damage to the cylinder body, the high-pressure gas cylinder leak-proof module located outside the high-pressure gas cylinder can effectively prevent the leaked hydrogen from entering the external environment; thereby, the continuous increase in the hydrogen concentration in the environment can be suppressed, reducing the safety hazards caused by hydrogen leakage to the external environment; the leaked hydrogen will enter the hollow interlayer. Since the hollow interlayer is filled with an inert gas with relatively stable chemical properties, the inert gas is not easy to react with the hydrogen, thereby ensuring the stability of the hydrogen in the hollow interlayer.

[0015] Optionally, the hydrogen safety monitoring module is also used to monitor the air pressure value in the hollow interlayer in real time. When the hydrogen safety monitoring module monitors that the air pressure value in the hollow interlayer reaches the trigger condition, the hydrogen safety monitoring module sends a trigger signal to control the intelligent navigation module to start; a fault display module is provided on the intelligent chassis carrying and transporting module, and the fault display module is used to display the cause of the current leakage fault.

[0016] By adopting the above technical solution, when hydrogen leaks into the hollow interlayer, the air pressure value in the hollow interlayer will continue to increase; when the hydrogen safety monitoring module detects that the air pressure value in the hollow interlayer has reached the trigger condition, the hydrogen safety monitoring module will also send a trigger signal to control the start-up of the intelligent navigation module; at this time, the fault display module will display the current cause of the leakage. If the current cause of the fault is displayed as the hydrogen concentration value in the environment has reached the trigger condition, it indicates that a leak has occurred in the pipeline of the high-pressure gas cylinder; if the current cause of the fault is displayed as the air pressure value in the hollow interlayer has reached the trigger condition, it indicates that a leak has occurred in the high-pressure gas cylinder; the fault display module facilitates safety personnel to accurately and intuitively find the fault point, thereby improving the efficiency of fault handling.

[0017] Optionally, it also includes: a fuel cell operation management module, which is used to monitor the fuel cell operation data in real time. The operation data includes at least the fuel cell power generation voltage, the fuel cell power generation current, the total operation time of the fuel cell, the fuel cell temperature, and the operation information of various valves; and upload the monitored fuel cell operation data to the storage device in real time.

[0018] By adopting the above technical solution, in order to ensure that the fuel cell stack is in a normal working state, the fuel cell stack operation data is monitored in real time through the fuel cell stack operation management module, so that the safety officer can intuitively understand the working status of the fuel cell stack; and when the operation data is abnormal, the safety officer can repair the fault point in time to ensure the normal operation of the fuel cell stack; later, the safety officer can download and analyze the stored fuel cell stack operation data through the storage device.

[0019] Optional, also includes:

[0020] A maintenance alarm module, when the stack operation management module detects that any operation data of the stack is abnormal, the stack operation management module sends a corresponding fault maintenance signal to the maintenance alarm module, and the maintenance alarm module issues a corresponding alarm signal according to the received fault maintenance signal;

[0021] A fuel cell maintenance room, which is arranged at a safe distance from the hydrogen maintenance room and can also be used as the end point of a preset route for the intelligent navigation module;

[0022] The battery stack carrying and transporting module is controlled by the intelligent navigation module and is used to carry and transport the battery stack; the intelligent navigation module is controlled by the fault repair signal sent by the battery stack operation management module. After receiving the fault repair signal, the intelligent navigation module controls the battery stack carrying and transporting module to transport the battery stack to the designated battery stack maintenance room.

[0023] By adopting the above technical solution, when the stack operation management module detects that any operation data of the stack is abnormal, it indicates that a fault has occurred inside the stack. At this time, the stack operation management module will send a corresponding fault repair signal to the maintenance alarm module based on the abnormal operation data detected. The maintenance alarm module will send a corresponding alarm signal based on the received fault repair signal. At this time, the safety officer can accurately determine the operating data that has failed through the alarm signal, so that the corresponding fault point can be found more conveniently and quickly. When the intelligent navigation module receives the fault repair signal sent by the stack operation management module, the intelligent navigation module will control the stack carrying and transporting module to transport the stack to the designated stack maintenance room; thereby, the faulty stack can be separated from the high-pressure gas cylinder, reducing the occurrence of safety accidents. The safety officer only needs to wait in the stack maintenance room without entering the fault site, which also ensures the safety of the safety officer.

[0024] Optional, also includes:

[0025] The stack interface detection module is used to regularly detect various important performance data of the stack interface through detection methods including infrared detection, radiation, and ultrasonic detection; the stack interface detection module is provided with a detection information storage unit, which is used to store the detection date of the stack detection module, the cause of the stack failure, the time of the last detection, and the expected time of the next detection.

[0026] By adopting the above technical solution, since the safety and sealing of the stack interface are directly related to the normal operation of the stack, testing the important performance data of the stack interface is an important part of ensuring the normal operation of the stack; regular testing can timely identify the faulty stack interface, thereby reducing unnecessary hydrogen energy consumption and ensuring the safety of the stack; the detection information storage unit makes it convenient for safety personnel to check the detection information of the stack, and by analyzing the detection information of the stack, the service life of the stack and the stack interface can be more accurately calculated.

[0027] Optionally, the intelligent navigation module is controlled by the battery stack interface detection module. When the battery stack interface detection module detects that any performance data of the battery stack interface does not meet the standard, the battery stack interface detection module controls the intelligent navigation module to start, and the intelligent navigation module controls the battery stack carrying and transporting module to transport the battery stack to the designated battery stack maintenance room.

[0028] By adopting the above technical solution, in order to ensure the subsequent normal operation of the fuel cell stack, when the fuel cell stack interface detection module detects that the performance data of the fuel cell stack interface does not meet the standards, the fuel cell stack interface detection module will control the intelligent navigation module to start, and the intelligent navigation module will control the fuel cell stack carrying and transporting module to transport the fuel cell stack to the designated fuel cell stack maintenance room. By timely repairing the fuel cell stack interface, the danger caused by hydrogen leakage at the fuel cell stack interface can be effectively reduced.

[0029] Optional, also includes:

[0030] An automatic docking module, an automatic docking module, is used to control the automatic docking of the high-pressure gas cylinder on the intelligent chassis carrying transport module with the corresponding fuel cell stack air inlet; the automatic docking module includes a first position sensor for being arranged at the air supply port of the high-pressure gas cylinder pipeline, a second position sensor for being arranged at the fuel cell stack air inlet, and an automatic pairing unit for controlling the pairing of the first position sensor with the designated second position sensor; when the first position sensor is successfully paired with the designated second position sensor, the automatic pairing unit controls the access network connection module to automatically complete the docking of the high-pressure gas cylinder pipeline with the fuel cell stack air inlet.

[0031] By adopting the above technical solution, when the high-pressure gas cylinder needs to be reconnected to the fuel cell stack air inlet after maintenance, the intelligent chassis carrying and transporting module is controlled by the intelligent navigation module to move to the designated side of the fuel cell stack air inlet. At this time, the first position sensor will be paired with the designated second position sensor. When the first position sensor and the second position sensor are successfully paired, the automatic pairing unit will control the access network connection module to automatically complete the docking of the high-pressure gas cylinder pipeline and the fuel cell stack air inlet. The entire docking work does not require human intervention. Compared with the manual docking method, the docking accuracy is improved, and the intelligent access of the high-pressure gas cylinder to the network is realized.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] By removing the leaking high-pressure gas cylinder from the accident site, the continued rise in hydrogen concentration at the scene can be effectively suppressed, ensuring safety at the accident site. The entire high-pressure gas cylinder transportation process is completed fully automatically, achieving unmanned, intelligent management and protecting the safety of the safety officer. When the intelligent navigation module receives a fault repair signal from the fuel cell operation management module, it controls the fuel cell transport module to transport the fuel cell to a designated fuel cell maintenance room. This allows the faulty fuel cell to be separated from the high-pressure gas cylinder, reducing the risk of safety accidents. The safety officer only needs to wait in the fuel cell maintenance room, without having to enter the fault site, which also ensures the safety of the safety officer.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] In this document, the term "and / or" simply describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document, unless otherwise specified, generally indicates an "or" relationship between the related objects.

[0040] The embodiment of the present application discloses a smart chassis carrying hydrogen power generation system. Figure 1 The intelligent chassis-based hydrogen power generation system includes an intelligent chassis-based transport module 1, an intelligent navigation module 2, an access network connection module 3, a hydrogen safety monitoring module 4, a hydrogen maintenance room 5, a high-pressure gas cylinder leak prevention module 6, a fuel cell operation management module 7, a maintenance alarm module 8, a fuel cell transport module 9, a fuel cell maintenance room 90, a fuel cell interface detection module 10, and an automatic docking module 12. Each module can include a central processing unit such as a CPU or MPU, or a host system built around a CPU or MPU, including both hardware and software. Programming allows users to freely control each module, ensuring it operates as desired.

[0041] As shown in the figure, the intelligent chassis-carrying transport module 1 can be a smart mobile cart or a smart chassis vehicle. The intelligent chassis-carrying transport module 1 is used to carry and transport high-pressure gas cylinders. The intelligent navigation module 2 is used to control the intelligent chassis-carrying transport module 1 to travel along a preset route. The intelligent navigation module 2 can use satellite positioning. Satellite positioning interfaces and protocols, namely GNSS, include but are not limited to: GPS protocol, Beidou protocol, GLONASS protocol, Galileo protocol, etc., and more commonly, the NMEA-0183 standard protocol. The intelligent navigation module 2 can also use wireless positioning interfaces and protocols, including but not limited to: LBS (base station positioning) or MPS (mobile positioning), and positioning using numbered road markers.

[0042] As shown in the figure, the access network connection module 3 is used to connect the high-pressure gas cylinder pipeline to the fuel cell stack's air inlet. This module uses aviation plugs to supply gas between the high-pressure gas cylinder and the fuel cell stack. Aviation plugs are installed at the pipeline's air inlet and the fuel cell stack's air inlet, respectively. To ensure the proper connection of the aviation plugs, multiple designated pipelines of high-pressure gas cylinders located on the same intelligent chassis transport module 1 can be connected using the same aviation plug.

[0043] As shown in the figure, the hydrogen safety monitoring module 4 uses a hydrogen sensor to monitor the hydrogen concentration in the environment in real time. A preset hydrogen concentration value set by humans is set in the hydrogen safety monitoring module 4. When the hydrogen safety monitoring module 4 detects that the hydrogen concentration in the surrounding environment exceeds the preset hydrogen concentration value, the signal output end of the hydrogen safety monitoring module 4 will send a trigger signal to the intelligent navigation module 2. At this time, the intelligent navigation module 2 will control the intelligent chassis carrying and transporting module 1 to start. The intelligent chassis carrying and transporting module 1 will automatically drive to the hydrogen maintenance room 5 under the navigation of the intelligent navigation module 2. When the intelligent chassis carrying and transporting module 1 starts to move, it will automatically cut off the access network connection module 3, thereby separating the high-pressure gas cylinder pipeline from the fuel cell. The hydrogen maintenance room 5 is used to be set at a safe distance from the fuel cell. At this time, the hydrogen maintenance room 5 will be the default end point of the preset route of the intelligent navigation module 2. By removing the leaking high-pressure gas cylinder from the accident site, the continuous increase in hydrogen concentration at the accident site can be effectively suppressed, ensuring the safety of the accident site. The entire high-pressure gas cylinder transportation process is completed fully automatically, realizing unmanned and intelligent management, and ensuring the life safety of safety personnel.

[0044] As shown in the figure, the high-pressure gas cylinder leak prevention module 6 includes a sealed canister covering the exterior of the high-pressure gas cylinder. A hollow interlayer is formed between the sealed canister and the high-pressure gas cylinder. The hollow interlayer is filled with an inert gas. The inert gas must be non-reactive with hydrogen; in this embodiment, helium is used. The hydrogen safety monitoring module 4 also includes a pressure sensor for real-time monitoring of the air pressure within the hollow interlayer. A preset pressure value is set within the hydrogen safety monitoring module 4. When the pressure sensor detects that the air pressure within the hollow interlayer exceeds the preset pressure value, the hydrogen safety monitoring module 4 also transmits a trigger signal to activate the intelligent navigation module 2. At this time, the intelligent chassis carrying and transporting module 1 automatically drives to the hydrogen maintenance room 5 under the guidance of the intelligent navigation module 2. The intelligent chassis carrying and transporting module 1 is equipped with a fault display module 11. The fault display module 11 includes at least a processor for processing fault information and a display connected to the processor. The display is configured to receive the processing signal sent by the processor and display the cause of the leakage fault. The specific causes of leakage failure can be divided into: the air pressure in the hollow interlayer increases, causing leakage of the high-pressure gas cylinder; and the hydrogen concentration in the environment exceeds the standard, causing leakage of the high-pressure gas cylinder pipeline.

[0045] As shown in the figure, the stack operation management module 7 is used to monitor the stack operation data in real time. The operation data includes at least the stack generation voltage, stack generation current, total stack operation time, stack temperature, and various valve operation information. The stack operation management module 7 can upload the monitored stack operation data to a storage device in real time. When the operation data is abnormal, the safety officer can promptly inspect and repair the fault point of the stack to ensure the normal operation of the stack. Later, the safety officer can also export the stored stack operation data through the storage device to facilitate analysis of the specific data.

[0046] As shown in the figure, the maintenance alarm module 8 includes an optoelectronic integrated alarm. When the stack operation management module 7 detects that any of the operation data of the stack is abnormal, the stack operation management module 7 will send a corresponding fault maintenance signal to the maintenance alarm module 8, and the maintenance alarm module 8 will send a corresponding alarm signal based on the received fault maintenance signal. For example, when the stack operation management module 7 detects that the operation data of the stack power generation voltage is abnormal, the stack operation management module 7 will send a voltage fault maintenance signal to the maintenance alarm module 8, and then the alarm of the maintenance alarm module 8 will emit a sound and red light alarm signal. When the stack operation management module 7 detects that the operation data of the stack power generation current is abnormal, the alarm of the maintenance alarm module 8 will emit a sound and blue light alarm signal.

[0047] As shown in the figure, the stack transport module 9 is controlled by the intelligent navigation module 2 and is used to carry and transport the stack. The intelligent navigation module 2 is controlled by the fault repair signal sent by the stack operation management module 7. After receiving the fault repair signal, the intelligent navigation module 2 controls the stack transport module 9 to transport the stack to a designated stack maintenance room 90. At this time, the stack maintenance room 90 is the default destination of the preset route of the intelligent navigation module 2. The stack maintenance room 90 is designed to be located at a safe distance from the hydrogen maintenance room 5.

[0048] As shown in the figure, the stack interface detection module 10 is used to perform regular detection of various important performance data of the stack interface through detection methods including infrared detection, radiation, and ultrasonic detection. The time and cycle of regular detection can be set manually. The stack interface detection module 10 is provided with a detection information storage unit 101. The detection information storage unit 101 is used to store the historical detection date of the stack interface detection module 10, the historical stack failure cause, the time of the last detection, and the expected time of the next detection. The safety officer can export the data in the detection information storage unit 101 to facilitate the later analysis of the failure cause and the stack life.

[0049] As shown in the figure, the intelligent navigation module 2 is also controlled by the battery stack interface detection module 10. When the battery stack interface detection module 10 detects that any performance data of the battery stack interface is abnormal, the battery stack interface detection module 10 will control the intelligent navigation module 2 to start. At this time, the battery stack maintenance room 90 is used as the preset route end point of the intelligent navigation module 2 by default. The intelligent navigation module 2 will control the battery stack carrying and transporting module 9 to transport the battery stack to the designated battery stack maintenance room 90.

[0050] As shown in the figure, the automatic docking module 12 is used to control the automatic docking of the high-pressure gas cylinder on the intelligent chassis carrying and transporting module 1 with the corresponding fuel cell stack. The automatic docking module 12 includes a first position sensor 121 located at the gas inlet of the high-pressure gas cylinder pipeline, a second position sensor 122 located at the gas inlet of the fuel cell stack, and an automatic pairing unit 123 for controlling the pairing of the first position sensor 121 with the designated second position sensor 122. When the intelligent chassis carrying and transporting module 1 carrying the high-pressure gas cylinder automatically drives into the pairing range of the automatic pairing unit 123 under the guidance of the intelligent navigation module 2, the automatic pairing unit 123 will control the first position sensor 121 to wirelessly pair with the designated second position sensor 122. At this time, the automatic pairing unit 123 will transmit the accurate position signal of the second position sensor 122 to the intelligent navigation module 2. Subsequently, under the control of the intelligent navigation module 2, the intelligent chassis carrying and transporting module 1 will move directly in front of the second position sensor 122, ensuring that the first position sensor 121 and the second position sensor 122 are directly aligned. The aviation plug of the network connection module 3 can be configured as a telescopic structure controlled by a drive source, which is controlled by the automatic pairing unit 123. When the first position sensor 121 is aligned with the designated second position sensor 122, the automatic pairing unit 123 controls the drive source to automatically complete the docking of the aviation plug on the high-pressure gas cylinder pipeline with the aviation plug on the fuel cell stack air inlet.

[0051] The implementation principle of the intelligent chassis-carrying hydrogen power generation system in the embodiment of the present application is as follows: when a high-pressure gas cylinder leaks, the hydrogen concentration value in the environment will continue to rise. When the hydrogen safety monitoring module 4 detects that the hydrogen concentration value in the environment has reached the trigger condition, the intelligent navigation module 2 will start under the control of the trigger signal sent by the hydrogen safety monitoring module 4. At this time, the intelligent chassis-carrying transportation module 1 will move the high-pressure gas cylinder away from the fuel cell according to the preset route under the navigation of the intelligent navigation module 2, so as to disconnect the access network connection module. Finally, the intelligent chassis-carrying transportation module 1 will automatically drive into the hydrogen maintenance room 5. Since a safe distance is maintained between the hydrogen maintenance room 5 and the fuel cell, the probability of the leaking high-pressure gas cylinder reacting with the fuel cell and causing an explosion can be greatly reduced, thereby ensuring the personal safety of the safety officer. In addition, the safety officer does not need to enter the leak site to repair the high-pressure gas cylinder. He only needs to wait in the hydrogen maintenance room 5 for the intelligent chassis carrying and transporting module 1 to deliver the high-pressure gas cylinder. By removing the leaking high-pressure gas cylinder from the accident site, the hydrogen concentration value at the accident site can be effectively suppressed from continuing to rise, ensuring the safety of the accident site. The entire high-pressure gas cylinder transportation process is completed automatically, realizing unmanned and intelligent management, and protecting the safety of the safety officer. When the intelligent navigation module 2 receives the fault repair signal sent by the battery stack operation management module 7, the intelligent navigation module 2 will control the battery stack carrying and transporting module 9 to transport the battery stack to the designated battery stack maintenance room 90; thereby, the faulty battery stack can be separated from the high-pressure gas cylinder, reducing the occurrence of safety accidents.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
