Abstract
Description
Technical Field
[0001] The utility model relates to a foam fire sprinkler system, in particular to a field space fire sprinkler technology that is configured through the structure of a co-pipeline and functions such as high-density fine mist foam liquid generation. Background Art
[0002] In recent years, with the significant technological breakthroughs in lithium batteries and other battery technologies, electric vehicles, charging stations, electric parking lots with charging piles, and battery energy storage sites (such as electric energy storage cabinets or electric energy storage stations) have sprung up and are everywhere. Furthermore, lithium battery energy storage has brought hot investment opportunities to the world. However, the risk of thermal runaway of lithium batteries has brought hidden dangers to investment and construction in photovoltaics, energy storage, charging piles and parking lots. Fires caused by thermal runaway of lithium batteries continue to occur around the world and have caused constant disputes between investors and residents. In addition, scholars and experts have found that the cause of thermal runaway of lithium batteries is roughly the electrochemical reaction caused by the melting of crystal dendrites and breathable membranes, which leads to the compatibility of positive and negative electrolytes. When the temperature rises rapidly at 125 to 135 degrees, the bulge triggers an electrochemical spontaneous combustion chain reaction. When a fire accident occurs, until now, scholars and experts around the world have not found a truly effective fire extinguishing technology to suppress lithium battery fires.
[0003] Generally speaking, due to the internal structure of lithium batteries, after the fire is extinguished, thermal runaway and re-ignition will occur again due to electrochemical reactions, which increases the difficulty of fire fighting and disaster relief. If a fire occurs in an electric vehicle, it will be even more difficult to extinguish the fire directly from the outside because the vehicle's power lithium battery pack is installed on the chassis of the electric vehicle and is covered with a sealed metal box. The fire caused by thermal runaway of the lithium battery will instantly explode (hydrogen explosion). The high temperature flame (about 2500 degrees) is caused to burn upward, resulting in the lithium battery pack covering the melting, causing the decoration inside the car to burn, thus causing the two side windows and the front and rear windshields to break, so that a fire extinguishing channel can be created, and thus about tens of tons of water are needed to achieve the purpose of fire extinguishing. According to statistics, this water consumption is about 10 times the water consumption of ordinary car fires, and the fire extinguishing time is more than 10 times that of ordinary car fires. Therefore, how to solve the fire risk caused by thermal runaway of lithium batteries has become a technical issue that the industry in the relevant technical field is eager to solve and challenge.
[0004] As far as we know, the patent cases related to this utility model are as follows:
[0005] 1. Taiwan Invention Announcement No. I794073, "Plane-type electric vehicle fire extinguishing facility", has a peripheral wall, a water mist fire extinguishing device and a waterproof door assembly, wherein the peripheral wall extends upward from the ground and surrounds the parking space, an entrance and exit are formed on the peripheral wall, the water mist fire extinguishing device can spray water mist toward the parking space, the waterproof door assembly is installed near the entrance and exit, and has an automatically retractable waterproof door, which can close the entrance and exit. Although the patent has the function of electric vehicle fire extinguishing, it does not have a co-pipeline structure configuration and high-density fine mist foam liquid generation and other functional settings, so that it cannot be customized according to different field spaces, resulting in poor fire extinguishing efficiency, slow fire extinguishing speed, and slow fire scene cooling.
[0006] 2. Taiwan Invention Announcement No. I803316 “Fire Fighting System” includes a fluid unit, a sensing unit and a control unit. The fluid unit is adjacent to the lower part of the parking area. The fluid unit is bent upward from the bottom surface of the lower part into an L shape, and is correspondingly arranged at the bottom of the front or rear of the electric vehicle; the sensing unit senses the ambient temperature of the parking area and generates temperature information. When the temperature information is greater than or equal to the first critical temperature, the control unit controls the fluid unit to output fluid to the lower part of the parking area and the bottom of the electric vehicle. Although this patent has the function of extinguishing fires in electric vehicles, it also does not have the function of co-pipeline structure configuration and high-density fine mist foam liquid generation, so that it is impossible to perform exclusive customized configuration according to different field spaces, resulting in poor fire extinguishing efficiency, slow fire extinguishing speed, and slow fire scene cooling.
