Description

Technical Field

[0001] The utility model belongs to the field of fire fighting and extinguishing, and specifically relates to an electric bicycle charging fire prevention device and a fire detection and extinguishing device. Background Art

[0002] At present, the use of electric bicycles is very common. For charging the power batteries inside, most communities now use charging centralized management equipment. A charging controller controls several charging sockets installed on a long mounting pole. Each charging socket corresponds to a charging parking unit in front. Although the charging is managed on a regular basis, it is safer than charging by pulling wires without charging centralized management equipment, but the potential safety hazards have not been completely eliminated. This is mainly because when charging, each electric bicycle is placed in the position of the charging parking unit, and then the charging power socket of the charging centralized management equipment and the charging socket on the electric bicycle are connected with their own chargers for charging. Since the quality of the chargers of each vehicle is uneven and the quality of the batteries is different, many people use inferior chargers and inferior batteries for cheapness, which can easily cause overcharging of the power battery, damage the power battery in the least, and cause excessive heating of the power battery, resulting in thermal runaway short circuit and fire, causing fire. Since there is no effective isolation and timely control of the fire after the fire, and the distance between each electric bicycle is small, once a fire occurs in one vehicle, it will affect other vehicles, and a burn is often a whole area, even causing casualties and a large amount of property losses.

[0003] Therefore, it is extremely urgent for us to technically solve the problem that a fire on an electric bicycle can easily affect other vehicles, and that after an electric bicycle catches fire, timely detection and measures can be taken to effectively control and extinguish the fire.
