Description

Technical Field

[0001] The invention relates to the technical field of power supply fire extinguishing, and in particular to a fire extinguishing system based on a solid-state hydrogen storage backup power supply. Background Art

[0002] With the continuous development and application of renewable energy around the world, people's demand for clean and efficient backup power technology is increasing. In this context, solid-state hydrogen storage backup power, as an emerging technology, is receiving more and more attention and application.

[0003] Solid-state hydrogen storage backup power supplies use solid-state hydrogen storage materials to store hydrogen and generate electricity through the reaction of hydrogen and oxygen, thereby providing a stable and reliable backup power supply for critical facilities. Compared with traditional backup power supply technologies, solid-state hydrogen storage backup power supplies have many advantages. First, it has high energy density and long-term storage capacity, and can provide continuous and stable power output. Secondly, solid-state hydrogen storage technology is not affected by factors such as seasons and weather, and has high reliability and stability. In addition, there are almost no emissions during the operation of solid-state hydrogen storage backup power supplies, which has good environmental protection. However, solid-state hydrogen storage backup power supplies also face potential fire and explosion risks, which are mainly due to the flammability and explosiveness of hydrogen. Once a solid-state hydrogen storage device leaks or an accident occurs, it may cause a serious fire or even an explosion accident, causing serious damage to equipment, personnel and the environment. Therefore, effective measures must be taken to reduce the fire risk of solid-state hydrogen storage backup power supplies.

[0004] Therefore, as a clean and efficient backup power technology, solid-state hydrogen storage backup power has broad application prospects. However, in the face of potential fire and explosion risks, effective fire-fighting measures must be taken to ensure its safe and reliable operation. Through continuous research and innovation, the safety and reliability of solid-state hydrogen storage backup power can be further improved, promoting its widespread application in key facilities and emergency sites.

[0005] Most of the current inventions of fire extinguishing systems and fire warning systems are for automotive fuel cells or automotive power batteries. There are almost no fire extinguishing systems based on backup power supplies, and solid-state hydrogen storage backup power supplies are usually installed in key facilities or places, such as hospitals, communication base stations, data centers, etc., so the safety of equipment and the environment is crucial. An effective fire extinguishing system can help protect equipment from damage by fire and reduce the impact on the surrounding environment. For example, the existing scheme discloses a fire extinguishing system for vehicles, and a fire extinguishing system for vehicles. The fire extinguishing system is mainly used for vehicle-mounted fuel cell fire extinguishing. The existing scheme also discloses a long-lasting battery detector and its distributed fire warning system. The existing scheme discloses a long-lasting battery detector and is equipped with a sprinkler fire extinguishing device, but the fire extinguishing system can only cool the outer shell of the fuel cell package and cannot penetrate into the fuel cell to directly extinguish the fire.

[0006] In order to deal with the fire risk of solid-state hydrogen storage backup power supply, an effective fire extinguishing system is required. Therefore, the present invention designs a fire extinguishing system based on solid-state hydrogen storage backup power supply, which detects the working state of the backup power supply through temperature sensors and smoke sensors. When the working state of the backup power supply is abnormal, the fire extinguishing system intervenes, cuts off the hydrogen source from the solid-state hydrogen storage device, cuts off the connection with the power supply system, ensures that the fire does not spread, and then extinguishes the fire inside the backup power supply through the fire extinguishing system to ensure the safety of the backup power supply. Summary of the invention

[0007] The purpose of the present invention is to provide a fire extinguishing system based on a solid-state hydrogen storage backup power supply to solve the problems existing in the above-mentioned prior art. The fire extinguishing system can be controlled by a temperature sensor and a smoke sensor. When the temperature of the fuel cell is too high or a certain amount of smoke is generated, the fire extinguishing system is automatically started to ensure that the fire is extinguished in the early stage of the fire, thereby ensuring the safety of the backup power supply. The system can also penetrate deep into the fuel cell to extinguish the fire from the root. Even when a fire occurs, the fire can be quickly extinguished in the early stage, thereby ensuring the safety of the backup power supply and preventing the risk of fire in other equipment caused by the fire of the backup power supply.

DETAILED DESCRIPTION

[0038] 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] like Figure 1 As shown, this embodiment discloses a fire extinguishing system based on a solid-state hydrogen storage backup power supply, including: a solid-state hydrogen storage module for storing hydrogen; a backup power supply module for utilizing the stored hydrogen to power equipment that requires power; and a fire extinguishing module for extinguishing a fire inside the backup power supply module when an abnormality occurs in the working state of the backup power supply module.

[0041] The fire extinguishing module includes: an abnormal monitoring submodule for monitoring the working state of the backup power module; and a fire extinguishing submodule for extinguishing the fire inside the backup power module when the working state of the backup power module is abnormal.

[0042] The abnormality monitoring submodule includes: a temperature control sensor unit, which is used to obtain the operating temperature inside the backup power supply module, convert the operating temperature into a first electrical signal, and output the first electrical signal; a smoke monitoring sensor unit, which is used to monitor whether excessive smoke is generated inside the backup power supply, convert the amount of smoke into a second electrical signal, and output the second electrical signal; wherein, the temperature control sensor unit is installed inside the backup power supply module, and the smoke monitoring sensor unit is installed outside the backup power supply module.

[0043] The fire extinguishing submodule includes: a first fire extinguishing unit, which is used to store a fixed amount of water; a second fire extinguishing unit, which is used to set an operating temperature threshold, receive a first electrical signal, and determine whether the operating temperature in the first electrical signal is higher than the operating temperature threshold. If the operating temperature is higher than the operating temperature threshold, the hydrogen detection solenoid valve is closed, the hydrogen delivery is cut off, the power supply switch 5 is disconnected, the power supply is cut off, and the water stored in the first fire extinguishing unit is used to extinguish the fire inside the backup power supply module. If the operating temperature is lower than the operating temperature threshold, the backup power supply module works normally, the hydrogen detection solenoid valve is in an open state, and the power supply switch 5 is in a closed state.

[0044] The fire extinguishing sub-module also includes: a third fire extinguishing unit, which is used to set a smoke volume threshold, receive a second electrical signal, and determine whether the smoke volume in the second electrical signal is higher than the smoke volume threshold. If the smoke volume is higher than the smoke volume threshold, the hydrogen detection solenoid valve is closed, the hydrogen delivery is cut off, the power supply switch 5 is disconnected, the power supply is cut off, and the water stored in the first fire extinguishing unit is used to extinguish the fire inside the backup power supply module. If the smoke volume is lower than the smoke volume threshold, the backup power supply module works normally, the hydrogen detection solenoid valve is in an open state, and the power supply switch 5 is in a closed state.

[0045] The first fire extinguishing unit includes: a water storage subunit for storing a fixed amount of water; a filtering subunit for filtering water entering the water storage subunit; a fire extinguishing pipe subunit for connecting with the water storage subunit, and when the working state of the backup power module is abnormal, the water stored in the water storage subunit is transported to the inside of the backup power module for fire extinguishing; a fire extinguishing pump subunit for being arranged on the fire extinguishing pipe subunit to extract the water stored in the water storage subunit, and the above contents specifically include:

[0046] The purpose of the present invention is to overcome the existing deficiencies and provide a fire extinguishing system 1 based on a solid-state hydrogen storage backup power supply. The working state of the backup power supply 4 is detected by a temperature sensor and a smoke sensor. When the working state of the backup power supply 4 is abnormal, the fire extinguishing system 1 intervenes to cut off the hydrogen source from the solid-state hydrogen storage device and the connection with the power supply system to ensure that the fire does not spread. Subsequently, the fire is extinguished inside the backup power supply 4 through the fire extinguishing system 1 to ensure the safety of the backup power supply 4.

[0047] The fire extinguishing system based on the solid-state hydrogen storage backup power supply is composed of a fire extinguishing system 1, a solid-state hydrogen storage system 2, a hydrogen side solenoid valve 3, a backup power supply 4, and a power supply switch 5.

[0048] The fire extinguishing system 1 is composed of a filter, a water tank, a fire extinguishing pipe, a fire extinguishing pump, a temperature control sensor, a smoke detection sensor, and a control module. The filter is mainly used to filter the water entering the water tank to prevent water containing impurities from entering the fuel cell during fire extinguishing, and to protect the fuel cell as much as possible. The water tank is located on the upper part of the backup power supply 4 and is used to store a certain amount of water. When the backup power supply 4 catches fire, it is used as firefighting water. The fire extinguishing pipe is connected to the water tank to transport the water in the water tank to the backup power supply 4. In particular, the water extinguishing pipe goes deep into the backup power supply 4, so that when a fire occurs, the water in the water tank can be transported to the backup power supply 4 in the first time, and the fire can be quickly extinguished at an early stage, thereby ensuring the safety of the backup power supply 4, and then preventing the risk of fire in other equipment caused by the fire of the backup power supply 4. The fire extinguishing pump is arranged in the middle of the fire extinguishing pipe, and is used to extract water from the water tank. At the same time, it can apply pressure to the water in the fire extinguishing pipe, so as to extinguish the fire more quickly. The temperature sensor is installed inside the backup power supply 4 to obtain the operating temperature inside the backup power supply 4. When the temperature inside the backup power supply 4 is too high, it is determined that the backup power supply 4 is on fire, and the operating status of the backup power supply 4 is monitored in real time. The smoke sensor is installed on the outer surface of the backup power supply 4 to monitor whether excessive smoke is generated inside the backup power supply 4. When the backup power supply 4 generates excessive smoke, it is determined that the backup power supply 4 is on fire. The control module is used to receive the electrical signals generated by the temperature sensor and the smoke sensor and control the operation of the fire extinguishing system 1, and is provided with a threshold that can be triggered repeatedly. According to the electrical signal, a decision is made on the opening and closing of the hydrogen side solenoid valve 3 and the power switch 5, that is, when the electrical signal is within the threshold, that is, when the backup power supply 4 works normally, the hydrogen detection solenoid valve is in an open state and the power switch 5 is in a closed state. When the electrical signal is abnormal and reaches beyond the threshold, that is, when the backup power supply 4 works abnormally, the hydrogen side solenoid valve 3 is in a closed state and the power switch 5 is in a disconnected state, and the hydrogen and current are cut off in time to prevent a large amount of hydrogen in the pipeline or the backup power supply 4 when the backup power supply 4 is on fire, thereby causing an explosion. At the same time, it also prevents the fire of the backup power supply 4 from burning through the cable to the power supply facilities, thereby causing the power supply facilities to catch fire. When the electrical signals generated by the temperature sensor and the smoke sensor return to within the threshold, the fire extinguishing system 1 stops working, and when the electrical signals generated by the temperature sensor and the smoke sensor reach outside the threshold, the fire extinguishing system 1 is started again, thereby effectively preventing the backup power supply 4 from re-igniting.

[0049] The solid-state hydrogen storage system 2 is the hydrogen source of the backup power supply 4. Hydrogen is stored by using solid-state hydrogen storage technology. When the city power fails and the power supply stops, the hydrogen stored in the solid-state hydrogen storage system 2 is transported to the backup power supply 4 through the pressure reducing valve. The backup power supply 4 starts working to provide temporary power for the power supply facilities.

[0050] The hydrogen side solenoid valve 3 is mainly controlled by the fire extinguishing system 1. When the fire extinguishing system 1 is not working, that is, the backup power supply 4 is working normally, the hydrogen side solenoid valve 3 is in an open state, and the hydrogen in the solid-state hydrogen storage system 2 can be normally transported to the backup power supply 4. When the working state of the backup power supply 4 is abnormal and it is determined that the backup power supply 4 is on fire, the fire extinguishing system 1 works, and the hydrogen side solenoid valve 3 is in a closed state, cutting off the connection between the solid-state hydrogen storage system 2 and the backup power supply 4 to prevent a large amount of hydrogen in the pipeline or the backup power supply 4 when the backup power supply 4 is on fire, thereby causing an explosion.

[0051] The backup power supply 4 is a power supply device that provides power to key facilities and places when the mains power fails. It is essentially a fuel cell that generates electricity through the chemical reaction of hydrogen and oxygen, where the hydrogen comes from the hydrogen stored in the solid-state hydrogen storage system 2 and the oxygen comes from the air.

[0052] The power switch 5 is used to control the connection between the power generated by the backup power supply 4 and the power supply facilities. The power switch 5, like the hydrogen side solenoid valve 3, is controlled by the fire extinguishing system 1. When the fire extinguishing system 1 is not working, that is, the backup power supply 4 is working normally, the power switch 5 is in the open state, and the power generated by the backup power supply 4 can be transmitted to the power supply facilities. When the working state of the backup power supply 4 is abnormal and it is determined that the backup power supply 4 is on fire, the fire extinguishing system 1 works and the power switch 5 is in the closed state, cutting off the connection between the backup power supply 4 and the power supply facilities to prevent the backup power supply 4 from burning through the cable to the power supply facilities when it catches fire, thereby causing a fire in the power supply facilities.

[0053] In this embodiment, if Figure 1 As shown, the fire extinguishing system based on the solid-state hydrogen storage backup power supply of the present invention mainly includes: a fire extinguishing system 1, a solid-state hydrogen storage system 2, a hydrogen side solenoid valve 3, a backup power supply 4, and a power switch 5. When the backup power supply 4 works normally, that is, when the temperature sensor and the smoke sensor in the fire extinguishing system 1 do not detect an abnormality, the hydrogen side solenoid valve 3 and the power switch 5 are in an open state, the hydrogen in the solid-state hydrogen storage system 2 can be normally transported to the backup power supply 4, and the electricity generated by the backup power supply 4 can also be normally transported to the power supply facilities to ensure the continuity and reliability of the power supply. When the backup power supply 4 works abnormally, that is, the temperature sensor or the smoke sensor detects that the operating temperature of the backup power supply 4 or the smoke around the backup power supply 4 is abnormal, first, the hydrogen side solenoid valve 3 and the power switch 5 are automatically set to the closed state to prevent more hydrogen from entering the backup power supply 4 to cause protection and prevent the fire from burning through the cable to the power supply facilities. Then the sensor will convert the temperature signal into an electrical signal and transmit it to the fire extinguishing pump. The fire extinguishing pump starts working, and the fire extinguishing system 1 starts to pump out the water in the water tank above the backup power supply 4 and apply pressure to transport it to the inside of the backup power supply 4 to quickly extinguish the fire.

[0054] The embodiments described above are only descriptions of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
