Description

Technical Field

[0001] The present invention relates to a fire extinguishing system, and particularly to an anti-fire and extinguishing system for electric vehicle parking spaces. Background Art

[0002] With the steady progress of the "dual carbon" policy and the development of the national energy transformation, electric vehicles, as an important part of energy conservation and carbon reduction, have been accepted by more and more families and enterprises in recent years with their development and maturity. Electric vehicles have many advantages such as low carbon, environmental protection, comfort, intelligence, and low use and maintenance costs, but there are also certain problems and challenges. At present, most automobile manufacturers use lithium batteries as energy storage media. Due to the physical and chemical properties of the battery pack, as the use time goes by and the battery pack ages and deforms, critical situations such as spontaneous combustion and deflagration often occur. Especially when an electric vehicle is charging, the rise and out-of-control of the battery temperature are more likely to cause spontaneous combustion and deflagration. In addition, the newly built residential communities, office buildings, etc. in cities now all have underground parking lots. Once a fire breaks out in an electric vehicle, not only is the fire difficult to control, but it will also spread rapidly to the surrounding areas. The generated gas is not only toxic but also has deflagration properties due to the influence of the enclosed space, posing a great threat to the safety of people's lives and property and imposing extremely high requirements on the evacuation and rescue time of precious people. How to control the spread of fire as much as possible and even extinguish the fire of an electric vehicle within a limited time has become an important topic in the fire prevention safety of electric vehicles. Studying an anti-fire and extinguishing system for electric vehicles that is easy to install, maintain, and popularize is of great significance for disaster prevention and reduction of electric vehicles.

[0003] Currently, for parking lots, especially underground parking lots, the rescue measures for fires are mainly designed and constructed for traditional fuel vehicles. For example, fire hydrants (water-based), fire extinguishers (foam, carbon dioxide, dry powder, etc.), sprinkler (water-based) facilities suspended above the parking spaces, etc. However, when an electric vehicle catches fire, it usually occurs in the battery pack located at the bottom of the vehicle, which instantly explodes and sprays flames, spreading rapidly. The existing measures mentioned above have limitations in preventing and extinguishing such fires. In response to this, various social forces have also conducted certain research and exploration, and formed some methods and means to reduce the harm of fires. For example, ground spray systems embedded under the parking spaces, fixed and movable spray partitions, movable ground spray devices, fire extinguishing balls installed above the parking spaces, etc. However, there are certain problems with the above fire prevention and extinguishing devices in terms of feasibility. For example, some devices require the pipelines to be embedded during the civil engineering stage or need civil engineering renovations to be implemented, which is difficult for existing buildings; some devices need to partition the parking spaces, causing inconvenience to the normal use of the parking spaces; some devices require centralized management and control, and it is difficult to effectively control distributed independently-owned parking spaces; some devices require personnel operation during a fire, especially in an enclosed space, which poses a threat to the personal safety of non-professionals and is not conducive to the early control of fires; some devices do not fully consider the fire characteristics of electric vehicles, etc. Summary of the Invention

Usually, it can charge at low peaks and discharge at high peaks to reduce the impact of the charging parking space on the power grid. In case of danger, it can be used as an emergency power supply to supply power to the system.

[0012] In a preferred example, the fire extinguishing agent storage tank can be integrated into the intelligent charging pile or set independently. The fire extinguishing agent can be water-based or other liquid fire extinguishing agents. The fire extinguishing agent storage tank is connected to the water spray port through a water pump module.

Further included is that the three-sided enclosed space can leave a fire fighting surface for rescue workers. Further included is that the four-sided enclosed space forms a fire extinguishing pool, and water is injected into it through the water injection port to submerge the battery pack to achieve the fire extinguishing effect.
