Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of fire extinguishing devices, and in particular to a flame retardant fire extinguishing device for a new energy vehicle. Background Art
[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as their power source, or use conventional vehicle fuels and new vehicle power devices, and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include hybrid vehicles, pure electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and extended-range electric vehicles.
[0003] New energy vehicles are powered by electricity and do not emit exhaust gas to cause air pollution. They significantly reduce the emission of harmful gases such as carbon dioxide and play a positive role in environmental protection. Compared with traditional fuel vehicles, new energy vehicles have lower operating costs because the cost of electricity is much lower than the cost of fuel.
[0004] New energy vehicles also have the problem of being prone to fire. The main reason why new energy vehicles are prone to fire is their battery system: 1. Battery thermal runaway: Battery thermal runaway is one of the most common causes of fire in new energy vehicles; 2. Battery immersion and collision damage; 3. Charging safety issues: Safety issues during charging should not be ignored. Internal short circuits in electric vehicle charging plugs, excessive input voltage of chargers, and long charging time may all cause fires. Internal short circuits in charging plugs may cause circuits to be connected in series, causing abnormal current increases; and excessive input voltage of chargers may burn transformer coils, causing equipment damage and possibly fires; 4. Battery quality and design defects: Instability of battery cell materials and failure of the battery management system (BMS) may cause battery overheating and fire. As the brain of the battery pack, BMS is responsible for monitoring battery status, predicting failures, and taking corresponding protective measures. If the BMS fails, it may not be able to detect and handle abnormal conditions such as battery overheating in time, thereby increasing the risk of fire.
[0005] New energy vehicles are generally charged in parking lots or charging stations. In the above areas, there are no corresponding flame retardant and fire extinguishing devices installed between cars. When one of the new energy vehicles catches fire, it will soon harm and ignite nearby cars, leading to a chain reaction, causing major property losses and safety accidents. In addition, when a fire occurs in the above areas, it is necessary to manually use a handheld fire extinguisher or water pipe to put out the fire, which has a lag and cannot be controlled and eliminated immediately. Summary of the invention
[0006] In order to overcome at least one of the technical problems existing in the prior art, the present invention provides a flame retardant and fire extinguishing device for new energy vehicles, which can automatically detect fire in a timely manner through fire detection equipment; can automatically deploy fireproof cloth through an electric drive device and a lifting frame to prevent the spread of fire; and can automatically extinguish fire through fire extinguishing equipment to ensure personal and property safety.
